Abstract

Purpose

The purpose of this paper is to implement a glass-curtain-wall cleaning robot driven by a double flexible rope, so as to replace manual cleaning. The glass-curtain-wall, because of its excellent daylighting performance, damp-proofing characteristics, heat insulation properties and aesthetics, is widely used in modern city buildings. For glass-curtain-wall buildings, regular cleaning of the glass-curtain-wall is necessary to ensure that the surface of the building appears clean and tidy, which in turn contributes toward preserving the overall aesthetic appearance of the city. Currently, the primary method of cleaning glass curtain walls is manual cleaning by workers on a suspended platform.

Design/methodology/approach

The mechanical structure of the proposed glass-curtain-wall cleaning robot driven by a double flexible rope is inspired by the way a spider moves by pulling its silk draglines in the air. For self-locking protection and increased rope friction, the robot’s moving section includes a worm reducer and multislot master–slave roller. The cleaning section comprises a water tank, control valve, shower nozzle and brush. The wall adsorbing section is realized by a double rotor. The workspace of the robot is analyzed. Flexible rope winding and unreeling control of the cleaning robot is deduced. The force of the cleaning robot when the double rotor is working is analyzed and calculated. The prototype of the glass-curtain-wall cleaning robot model driven by a double flexible rope is established, and experiments wherein the robot moves along a preset track, as well as cleaning experiments, are performed.

Findings

The prototype of the glass-curtain-wall cleaning robot model driven by a double flexible rope can move along the preset track, satisfy the design functions and clean effectively. The experimental results verify the validity and practicality of the robot.

Research limitations/implications

The implication of this research is that a glass-curtain-wall cleaning robot model driven by a double flexible rope fulfills the movement strategy and drive-type requirements for cleaning glass curtain walls. The limitation of this research is that it is difficult to implement rapid cleaning.

Originality/value

The traditional method of manual cleaning by workers on a suspended platform will be changed after the glass-curtain-wall cleaning robot is manufactured, and the advent of this cleaning robot for the low- and mid-rise buildings will reduce the cost of cleaning buildings, improve the working environment and enhance production efficiency.

Abstract

Purpose

The purpose of this paper is to comprehensively examine the influence of formal and informal institutional differences on enterprise investment margin, mode and result.

Design/methodology/approach

This paper is based on 2,440 micro samples of large-scale outbound investment from 609 Chinese enterprises from the years 2005 to 2016.

Findings

The study has found that formal institutional differences have little impact on investment scale, but significantly affect investment diversification. In order to avoid the management risks brought by formal institutional differences, enterprises tend to a full ownership structure. However, the choice between greenfield investment and cross-border mergers and acquisitions is not affected by formal institutional differences. In contrast, the impact of informal institutional differences is more extensive. Both formal and informal institutional differences significantly increase the probability of investment failure. Further research found that the Belt and Road Initiative (BRI) bridges the formal institutional differences.

Originality/value

The study concludes that developing the BRI, especially cultural exchanges with countries alongside the Belt and Road, will help enterprises to “go global” faster and better.

Abstract

Purpose

This paper explores the challenges of using cable-driven parallel robots on high-altitude, large-span facades, where redundancy in multicable systems and the elastic deformation of the cables are significant issues. This study aims to improve the accuracy and stability of the work platform through enhanced control strategies. These strategies address the redundancy in multicable systems and reduce the risks associated with cable deformation and mechanical failures during large-span movements.

Design/methodology/approach

The paper proposes a dynamic model for a four-rope parallel robot designed explicitly for large-span applications. The study introduces a position–force control strategy incorporating kinematic inverse solutions and a rope dynamics model to account for rope elasticity and its effects. This approach increases the number of system equations to match the unknowns, effectively solving the redundancy problem inherent in multicable systems. In addition, the tension changes of ropes and the stability of the working platform are examined under different motion distances (X = 50 m and X = 100 m) and varying Young’s modulus values (K = 5000 MPa and K = 8000 MPa).

Findings

This study’s large-span rope force–position control strategy successfully resolves the typical nonlinear characteristics and external disturbances in multicable parallel systems. By continuously monitoring and adjusting cable tension and end positions, this strategy ensures precise control over each cable’s tension, optimizes the distribution of cable tensions and maintains the system’s stability and response speed. The analysis in this paper indicates that this control strategy significantly improves the motion accuracy of robots operating on large-span high-altitude facades.

Practical implications

Industry adoption: The design and control strategies developed for the four-cable-driven parallel robot can be adopted by companies specializing in facade maintenance, construction or inspection. This could lead to safer, more efficient and cost-effective operations, especially in challenging environments like high-rise buildings. Innovation in robotic solutions: The research can inspire innovation within the field of robotics, particularly in developing robots for specific applications such as large surface maintenance. It showcases how adaptive control and stability can be achieved in complex operational scenarios. Safety improvements: By demonstrating a more stable and precise control mechanism for navigating large facades, the study could contribute to significant safety improvements, reducing the risk of accidents associated with manual facade maintenance and inspection tasks.

Originality/value

This paper combines the force/position hybrid control method with actual robotic applications, offering a novel solution to the complex issue of controlling cable-driven parallel robots in challenging environments. Thus, it contributes to the field. The proposed method significantly enhances the precision and stability of such systems and provides robust technical support for high-precision tasks in complex mechanical settings.

Abstract

Purpose

The Belt and Road Initiative (BRI) is the most comprehensive and substantial international cooperation platform, creating a new market influenced by economic and political factors. In this paper, the authors aim to examine whether and how the BRI impacts the Chinese enterprises' corporate environmental responsibility (CER).

Design/methodology/approach

Based on China's listed firms' database from 2011 to 2018, the authors use the PSM-DID method, an econometrics method combined with propensity score matching (PSM) and difference-in-differences (DID), to conduct causal inference between the BRI and Chinese enterprises' CER and conduct a series of robustness analyses. Moreover, the authors explore the mechanisms underlying the main effect from both market and non-market perspectives.

Findings

The results suggest that the BRI significantly increases Chinese enterprises' CER. Further analyses show that market competition and government support are two possible mechanisms through which the BRI has an effect on the enterprises' CER.

Originality/value

The research study supplements existing work on the environmental effects of the BRI at a microlevel and adds to the literature on the drivers of CER. The findings offer valuable insights into governments and scholars by demonstrating that CER is a crucial tool for Chinese enterprises to gain a competitive advantage in the increasingly competitive markets along the BRI.
