Description

Technical Field

[0001] The present invention relates to the technical fields of building facade operation and maintenance and intelligent equipment, and more specifically to the technical field of a building facade operation and maintenance mechanism with a bionic structure and a construction method. Background Art

[0002] At present, the operation and maintenance of building facades (cleaning, demolition, repair, etc.) mainly rely on high-altitude work by spider men, which poses a risk of falling objects from a height.

[0003] The patent with the publication number CN115142657A and the patent name "An intelligent climbing construction operation platform system for the facade of existing buildings and its operation method" discloses the following content: An intelligent climbing construction operation platform system for the facade of existing buildings and its operation method. Belonging to the technical field of the renovation construction of existing buildings in urban old communities, it includes an intelligent climbing system and a construction operation platform system; the C-shaped steel column of the intelligent climbing system is nested on the upper side of the parapet wall, so that the intelligent climbing construction operation platform system for the facade of existing buildings can be attached to the facade of existing buildings. The universal wheels arranged around the bottom of the installation box of the intelligent climbing system, the detachable support structure, and the support rod fixedly arranged on the front side of the C-shaped steel column can increase the overall safety and stability of the system; the intelligent climbing construction operation platform system for the facade of existing buildings and its operation method provided by the present invention solve the problems of difficult construction noise treatment and inability to arbitrarily adjust the horizontal and vertical construction operation platform areas according to the characteristics of existing buildings, and can be repeatedly disassembled and installed for the renovation construction of the facades of existing buildings in urban old communities without damaging the existing buildings. However, this patent cannot achieve a seamless connection between the construction platform and the building facade, and cannot prevent the risk of materials falling through the gap between the wall and the universal wheels during the operation.

[0004] The patent with the publication number CN112141340A and the patent name "A building facade repair device based on UAV technology" discloses the following content: A building facade repair device based on UAV technology. Aiming at the problem that existing UAVs are often used to repair building facades, and since modern buildings are getting taller and taller, it is very dangerous for workers to perform high-altitude operations when there is peeling on the facades of these high-rise buildings. The following solution is proposed. It includes a central processor, a UAV body, an image acquisition module, and a wall. The UAV body includes a main control module, a wireless transmission module, and a power module. In the present invention, the central processor issues commands to control the main control module to perform corresponding operations. The position of the UAV body is adjusted through the real-time transmitted images of the image acquisition module until the manipulator is in a horizontal state with the position on the wall that needs to be repaired. Then, the wall is repaired through the repair component, and the excess repair material is scraped off through the smoothing component. This is not only convenient for next use but also more beautiful, with a simple structure and convenient operation. However, the UAV in this patent needs to maintain a certain distance from the building, and the spraying equipment is also at a relatively far distance from the building facade. The UAV is greatly affected by the wind. While in this patent, during operation, it is adsorbed on the facade, and there is no shaking caused by wind vibration, which may lead to a reduction in the quality of the repair effect.

[0005] The equipment disclosed in the above patent can reduce the labor intensity of workers to a certain extent, but has a low degree of intelligence and low bionic degree. With the rapid development of intelligent construction equipment, a building facade operation and maintenance equipment with a bionic structure is proposed. Summary of the Invention

[0006] The purpose of the present invention is: To solve the above technical problems, the present invention provides a building facade operation and maintenance mechanism with a bionic structure.

[0007] The present invention specifically adopts the following technical solutions to achieve the above purpose:

[0008] One aspect of the present invention provides a building facade operation and maintenance mechanism with a bionic structure, including a wall-climbing robot crawling and adsorption part that crawls and adsorbs on the building facade through negative pressure, and an operation and maintenance operation part. The operation and maintenance operation part has a crawling and adsorption part with a negative pressure adsorption type octopus tentacle suction cup and a steel wire lifting connection part similar to spider silk.

[0009] The wall-climbing robot crawling and adsorption part includes a housing, a large negative pressure adsorption disk arranged at the bottom of the housing, multiple pairs of movable crawling and adsorption arms symmetrically arranged on the housing, a steel wire cable winch arranged inside the housing, a steel wire cable wound around the steel wire cable winch, a tension sensor arranged on the steel wire cable winch, a cable outlet arranged at the bottom of the housing, and one end of the steel wire cable winch passes through the cable outlet and is connected to the operation and maintenance operation part;

[0010] Each movable crawling adsorption arm can move 0°-30° on the horizontal plane of the large negative pressure adsorption plate, and 0°-15° on the vertical plane of the large negative pressure adsorption plate. Each movable crawling adsorption arm can be set in two modes: locking angle and unlocking angle.

[0011] Specifically, the bionic structure of this device is primarily inspired by the suction cups of an octopus's multi-clawed tentacles, which crawl along building facades through negative pressure. It also draws inspiration from the vertical mobility of spiders, which rapidly descend from their attachment points through silk. Based on these biological characteristics, a bionic structure for building facade maintenance has been developed.

[0012] In one embodiment, the number of the movable crawling adsorption arms is three pairs, and each pair of movable crawling adsorption arms is symmetrically arranged on the left and right sides of the shell.

[0013] Specifically, the three pairs of crawling adsorption arms fully meet the adsorption capacity of the crawling adsorption part of the wall-climbing robot when there is no load (no hanging) in the operation and maintenance operation part. When the large negative pressure adsorption plate is working, it can meet the load requirements of the operation and maintenance operation part under full load.

[0014] In one embodiment, each movable crawling adsorption arm is a two-section structure, and each movable crawling adsorption arm includes a first section arm hinged to the inside of the shell, a second section arm movably connected to the end of the first section arm, and a hinged structure is provided between the first section arm and the second section arm, and the adsorption arm has a negative pressure adsorption disk.

[0015] In one embodiment, the first section of the boom is a telescopic boom.

[0016] Specifically, the crawling arm has a two-section structure. The first section of the arm can be telescopically adjusted in length, and the first section and the second section of the arm can be rotated and moved, and have a good ability to climb over obstacles.

[0017] In one embodiment, the operation and maintenance operation unit includes an operation and maintenance material frame, power batteries of the operation and maintenance operation unit arranged on the left and right sides of the operation and maintenance material frame, a lifting structure connected to the wire rope cable arranged in the middle of the operation and maintenance material frame, and a detachable multifunctional operation robot arm installed in the middle of the operation and maintenance material frame. At least two rows of maintenance negative pressure adsorption plates are arranged on the outer wall inside the operation and maintenance material frame.

[0018] Specifically, the operation and maintenance department includes two rows of maintenance negative pressure adsorption plates on the left and right sides, power battery layers on the left and right sides, a lifting structure connected to the wire rope cable, and a detachable multifunctional operating robotic arm (including: special equipment for cleaning, special equipment for demolition, special equipment for spraying, etc.).

[0019] A second aspect of the present invention provides a method for installing a bionic structure building facade operation and maintenance mechanism, which uses the above-mentioned bionic structure building facade operation and maintenance mechanism, comprising the following steps:

[0020] S1. The climbing robot's crawling and adsorption part is adsorbed on the bottom of the building facade:

[0021] When the wall-climbing robot's crawling suction part adheres to the bottom of the building's facade, the three pairs of movable crawling suction arms' suction arm negative pressure suction plates are opened to stably adhere to the building's facade. At the same time, the unlocked wire cable winch is opened to ensure that the wire cable of the wall-climbing robot's crawling suction part can freely extend due to gravity during the crawling process.

[0022] S3, the wall-climbing robot's crawling adsorption unit strongly adsorbs the designated position:

[0023] The wall-climbing robot's crawling and adsorption part can achieve rapid movement like a spider by crawling upward, adsorbing, and locking through three pairs of movable crawling and adsorption arms on the left and right. When it reaches the designated position, the large negative pressure suction cup of the crawling and adsorption part of the wall-climbing robot will perform adsorption.

[0024] S4, wall-climbing robot crawling adsorption unit operation and maintenance department:

[0025] According to the maintenance requirements of the building facade, the designated robotic arm is replaced on the operation and maintenance operation unit; the crawling and adsorption part of the wall-climbing robot begins to retract the coiled wire cable, and the operation and maintenance operation unit can quickly rise to the designated area where operations are required; the two rows of negative pressure suction cups on the left and right sides of the operation and maintenance operation unit begin to work, making the operation and maintenance operation unit completely fit the building facade, preventing materials / construction waste in traditional equipment from falling from high altitude through the gap between the equipment and the building facade; at this point, the robotic arm begins to operate according to the operation situation.

[0026] S5. Replacement of turnover materials in the wall-climbing robot operation and maintenance department:

[0027] If it is a demolition robot arm, during the loading process of construction waste after the building facade is demolished, when the tension sensor reaches the limit load of the large negative pressure adsorption plate, the lowering wire cable is released to quickly lift the operation and maintenance unit to the ground for construction waste removal;

[0028] If it is a cleaning or spraying robot arm, after the cleaning agent and spray material in the operation and maintenance operation part are used up, the descending wire cable is released to quickly lift the operation and maintenance operation part to the ground for refilling of materials.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The adsorption capacity of existing crawling equipment is fixed. Excessive adsorption force will cause slower movement, and too little adsorption force will cause unstable adsorption and low safety. This solution adjusts the adsorption capacity according to different load conditions, which can achieve efficient operation. That is, the movement and adsorption of the crawling adsorption part of the wall-climbing robot can be guaranteed by the crawling adsorption arm, and the large negative pressure adsorption plate can realize the lifting of the full-load operation and maintenance operation part. This application separately establishes the adsorption capacity during crawling and the adsorption capacity during operation, achieving the effect of fast crawling and stable adsorption force during operation.

[0031] 2. The vertical and horizontal moving angles of the crawling arm, the articulation between the two arms, and the extension of the main arm can achieve a good ability to climb over obstacles (decorative lines on the facade of the building), which is basically not available in existing equipment.

[0032] 3. Compared with traditional crawling robots that rely on wheels or tracks for walking, this solution relies on the suction of part of the crawling arm to absorb the suction of the negative pressure suction plate during walking, while the other part crawls and absorbs at a higher position. The crawling arm can achieve a spider-like crawling effect by extending and contracting on the plane, vertical surface and rods;

[0033] 4. The working part passes through the crawling adsorption part which has been adsorbed to the designated position, and is lifted and lowered by the steel wire to quickly reach the designated position. At the same time, it adsorbs the surface to improve the stability of the operation.

[0034] 5. During the operation, the existing operation and maintenance work section can achieve complete adsorption and adhesion with the wall, without any gaps between the wall and the work section, thus preventing materials from falling during the demolition operation.
