Description

Technical Field

[0001] This application relates to the technical field of window cleaning machines, and in particular to a slewing bearing type walking drive device. Background Technology

[0002] Window cleaning machines are typically used for cleaning and maintaining the curtain walls of high-rise buildings. During operation, the machine's base moves along a pre-installed track on the building's roof, allowing it to be moved to the desired cleaning location. However, because building facades come in various shapes, the track must be adapted to the facade's shape during installation. This can lead to issues with insufficient bending angles at turns. Currently, the rollers on the base of most window cleaning machines are fixed, requiring a larger bending radius for proper movement. Insufficient bending radius makes it difficult for the machine's base to pass through smoothly, thus affecting its usability.

[0003] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0004] In order to enable the base of the window cleaning machine to move through guide rails with different turning angles and thus enhance the application range of the window cleaning machine, this application provides a slewing bearing type walking drive device.

[0005] This application provides a slewing bearing-type travel drive device, which adopts the following technical solution:

[0006] A slewing bearing type walking drive device includes a running box, a drive assembly connected to the running box for moving the running box, and a slewing bearing disposed on the running box. One end of the slewing bearing is fixed to the running box, and the other end of the slewing bearing is fixed to the base of the window cleaning machine.

[0007] By adopting the above technical solution, the running box can rotate relative to the base of the window cleaning machine. Thus, when the track has an angle, the running box can rotate as the track angle changes, allowing the window cleaning machine to pass through tracks with smaller angles, making the window cleaning machine more convenient to operate.

[0008] Optionally: The drive assembly includes a traveling wheel rotatably connected to the running box and a drive component that drives the traveling wheel to rotate. The output end of the drive component is connected to the traveling wheel, and the lower end of the traveling wheel abuts against the track.

[0009] By adopting the above technical solution, the driving component drives the traveling wheels to rotate, and the traveling wheels abut against the track and move on the track, driving the base of the window cleaning machine to move along the track. Furthermore, each traveling box is equipped with a driving component, so that each traveling box can move freely.

[0010] Optionally, the running box is also provided with several sets of anti-tipping components. The anti-tipping components are respectively set on both sides of the track. The anti-tipping components include a mounting plate set on the running box and a guide wheel rotatably connected to the mounting plate. The guide wheel abuts against the side wall of the track and rolls with the track.

[0011] By adopting the above technical solution, the guide wheels abut against the side wall of the guide rail, thereby restricting the running box to move only along the length of the rail. When the running box is installed on the base of the window cleaning machine, the base of the window cleaning machine usually has four or six running boxes installed, so the traveling wheels can be stably abutted against the rail, and the guide wheels can also be stably abutted against the rail, so that the window cleaning machine can be stably on the rail.

[0012] Optionally: the guide wheel located near the drive member abuts against the side wall at the upper end of the track, and the guide wheel located away from the drive member abuts against the side wall in the middle of the track.

[0013] By adopting the above technical solution, when it is necessary to enhance the structural strength of the track, a reinforcing rib can be set in the middle of the track, while the guide wheel located on one side directly abuts against the upper side wall of the track. There will be no contact between the guide wheel and the reinforcing rib, so that the movement of the guide wheel against the guide rail is not easily affected.

[0014] Optionally: The guide wheels are all located on the same side of the track, with the mounting plates close to each other, and the mounting plates cover the guide wheels on the side facing the length direction of the track.

[0015] By adopting the above technical solution, when the guide wheel moves along the track, the position of the guide wheel facing the direction of movement is blocked by the mounting plate, so that the debris can only come into contact with the mounting plate and not directly contact the guide wheel. This makes it less likely for the guide wheel to get tangled with debris when it rolls, and makes it less likely for the rotation of the guide wheel to be affected. At the same time, it also makes it less likely for debris to enter between the guide wheel and the track, and makes it less likely for the guide wheel to be stuck by debris and unable to rotate.

[0016] Optionally: A gap is left between the mounting plate and the upper surface of the track.

[0017] By adopting the above technical solution, the mounting plate is used to shield the wheels. When the wheels move on the track, the mounting plate pushes away any debris left on the track, making it difficult for debris to enter between the wheels and the track and obstruct the rotation of the wheels. This allows the wheels to move stably on the track.

[0018] Optional: Each mounting plate is provided with several fastening bolts, which are threaded into the running box.

[0019] By adopting the above technical solution, the mounting plate and the running box can be detachably connected. After the guide wheel wears out, the mounting plate can be directly removed and replaced, which also facilitates the initial installation and subsequent maintenance.

[0020] Optionally: Several heavy-duty anti-shear pins are jointly installed on the mounting plate and the running box, and the heavy-duty anti-shear pins are spaced apart from the fastening bolts.

[0021] By adopting the above technical solution, the connection strength between the mounting plate and the running box is enhanced by using heavy-duty anti-shear pins, making it less likely for the running box and the mounting plate to have relative positions, thereby reducing the shear force on the fastening bolts and making the fastening bolts less likely to break. At the same time, it can also be positioned when the mounting plate is connected to the running box, making the installation of the mounting plate more convenient.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The running box can rotate relative to the base of the window cleaning machine, so that when the track has an angle, the running box can rotate with the change of the track angle, allowing the window cleaning machine to pass through the track with a smaller angle, thus making the window cleaning machine more convenient to operate.

[0024] 2. By abutting against the side wall of the guide rail, the running box can only move along the length of the rail. When the running box is installed on the base of the window cleaning machine, the base of the window cleaning machine usually has four or six running boxes installed. Therefore, the traveling wheels can stably abut against the rail, and the guide wheels can also stably abut against the rail, so that the window cleaning machine can be stably on the rail.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a slewing bearing type travel drive device, such as... Figure 1 As shown, it includes a running housing 1, a drive assembly 2 mounted on the running housing 1 for moving the running housing 1, and a slewing bearing 3 mounted on the running housing 1. One end of the slewing bearing 3 is fixedly mounted to the upper end face of the running housing 1, and the other end of the slewing bearing 3 is fixedly mounted to the base of the window cleaning machine. Thus, during the operation of the base of the window cleaning machine, the running housing 1 can rotate relative to the window cleaning machine, making the movement of the window cleaning machine on the track smoother.

[0030] like Figure 1 and Figure 2 As shown, the drive assembly 2 includes a traveling wheel 21 rotatably connected to the running housing 1 and a drive component 22 that drives the traveling wheel 21 to rotate. In this embodiment, the drive component 22 is a motor. The running housing 1 has a lower opening, and the traveling wheel 21 is disposed in the lower opening of the running housing 1, with the lower end of the traveling wheel 21 lower than the running housing 1. The lower end of the traveling wheel 21 can abut against the H-shaped track. The drive component 22 is mounted on the side wall of the running housing 1 parallel to the track. The free end of the drive component 22 is connected to the traveling wheel 21 through a coupling, thereby driving the traveling wheel 21 to rotate. After the traveling wheel 21 rotates, it can drive the running housing 1 to move on the track.

[0031] The running housing 1 is also equipped with several anti-tipping components 4 to prevent it from tipping over. In this embodiment, there are four sets of anti-tipping components 4, two in each pair located on one side of the guide rail. Each anti-tipping component 4 includes a mounting plate 41 installed on the running housing 1 and a guide wheel 42 rotatably connected to the mounting plate 41. The mounting plates 41 are respectively installed on the side wall of the running housing 1 perpendicular to the length of the rail by fastening bolts 43. The fastening bolts 43 pass through the mounting plates 41 and are threaded into the running housing 1, thereby achieving a stable connection between the mounting plates 41 and the running housing 1. When the guide wheels 42 wear out, the mounting plates 41 can be directly disassembled and replaced.

[0032] Guide wheels 42 are mounted on the side walls of two mounting plates 41 located on the same side of the track. The guide wheel 42 located closer to the drive member 22 abuts against the vertical side wall of the upper end of the guide rail, while the guide wheel 42 located away from the drive member 22 abuts against the vertical side wall of the guide rail in the middle. Thus, even after adding reinforcing ribs to one side of the guide rail, the guide wheel 42 can still stably abut against the guide rail, thereby maintaining the stable movement of the running box 1.

[0033] To ensure the mounting plate 41 is stably and accurately positioned on the operating housing 1 during installation, several heavy-duty shear pins 44 are also installed on the operating housing 1. The ends of the heavy-duty shear pins 44 furthest from the operating housing 1 pass through the mounting plate 41, thus defining the position of the mounting plate 41. The heavy-duty shear pins 44 are spaced apart from the fastening bolts 43, and are all positioned between adjacent fastening bolts 43. The heavy-duty shear pins 44 further enhance the stability of the fastening bolts 43, preventing them from breaking due to excessive shear force, thus ensuring the mounting plate 41 is stably installed on the operating housing 1.

[0034] When the traveling wheel 21 moves on the track, debris can still fall onto the track. When this debris enters between the traveling wheel 21 and the track, it can cause slippage, affecting the driving force of the traveling wheel 21 on the running box 1. Therefore, the mounting plate 41 extends towards the upper surface of the guide rail, creating a gap between the mounting plate 41 and the upper surface of the guide rail. This allows the mounting plate 41 to pass over the guide rail, pushing away large pieces of debris that could affect the traveling wheel 21, preventing debris from easily entering between the traveling wheel 21 and the track, thus minimizing the impact on the movement of the running box 1.

[0035] To prevent the guide wheels 42 from being affected by debris during movement, the guide wheels 42 on the same side of the guide rail are all positioned between two adjacent mounting plates 41. The mounting plates 41 block the guide wheels 42 from facing the length direction of the rail. As the guide wheels 42 move on the rail, the mounting plates 41 can scrape away debris on the rail, preventing debris from directly contacting the guide wheels 42 and making the movement of the guide wheels 42 on the rail less affected.

[0036] The implementation principle of this embodiment is as follows: When the base of the window cleaning machine moves on the track, the orientation of the running box 1 can rotate relative to the base of the window cleaning machine as the angle of the track changes, so that the running box 1 can still move stably on the track while maintaining connection with the base of the window cleaning machine. When the base of the window cleaning machine tilts, the guide wheels 42 provided on the base of the window cleaning machine can maintain contact with the middle and upper part of the track, so that the running box 1 will not detach from the track, thereby enabling the running box 1 to work and move stably.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
