Description

Technical Field

[0001] This utility model relates to the field of window cleaning machine technology, and in particular to a roof track-type movable platform. Background Technology

[0002] Roof rails are a type of track system installed on the roof structure of buildings or structures, typically used to support, guide, or move rooftop work equipment. For the exterior facades and skylights of high-rise buildings, exterior wall cleaning, repair, glass replacement, and curtain wall maintenance all require specialized equipment to ensure the safety and stability of workers operating at heights. Among these, window cleaning machines have become a standard piece of specialized equipment for the maintenance of high-rise building exteriors.

[0003] Track-mounted window cleaning machines are widely used due to their mature structure, stable operation, and high safety. These machines typically mount a trolley on a roof track, allowing it to move stably along the track for cleaning or maintenance.

[0004] However, the following shortcomings still exist in existing rooftop track-mounted mobile devices: Some devices rely on electronic limit switches to stop the machine. If the limit switch fails or the control circuit malfunctions, the platform may run off the track or collide with the end structure, resulting in insufficient safety redundancy.

[0005] The platform is prone to tilting or shifting under crosswinds, eccentric loads, or local deformation of the track, which is detrimental to the safety of high-altitude operations.

[0006] In addition, there is a potential danger that the door may open outwards if people accidentally touch it when entering or exiting the platform. Summary of the Invention

[0007] Therefore, this utility model provides a roof-mounted track-type movable platform, which ensures stable platform movement and prevents it from surging off the end due to inertia or misoperation through electrical limiting, mechanical limiting and anti-tipping design.

[0008] To solve the above-mentioned technical problems, this utility model provides a roof-mounted track-type movable platform, connected to a track, comprising: Platform basketball hoop; The walking mechanism is connected to the platform basket. The walking mechanism includes a walking wheel that rolls in contact with the top surface of the track, anti-tilt wheels that are close to the two sides of the track, and a drive device that drives the walking wheel to rotate. A travel limit switch is connected to the travel mechanism; A limit stop bar is installed on the track, and the travel limit switch can contact the limit stop bar when the platform basket moves; A stop mechanism is provided on the track, and the platform basket can contact the stop mechanism when it moves.

[0009] In one embodiment of this utility model, the track is provided with two parallel tracks, and the walking mechanism is provided with two sets at both ends of the bottom of the platform basket along the length direction. The walking limit switches on the two sets of walking mechanisms are respectively provided on both sides of the platform basket along the width direction.

[0010] In one embodiment of this utility model, the walking mechanism includes connecting seats respectively connected to both ends of the platform basket in the width direction and a bracket connected to each connecting seat. The walking wheel is rotatably connected to the connecting seat. The driving device is connected to the connecting seat and its driving end is connected to the walking wheel. Two anti-tilt wheels are connected to the bracket. The axis of the anti-tilt wheel is perpendicular to the axis of the walking wheel.

[0011] In one embodiment of this utility model, the walking limit switch is connected to the bracket.

[0012] In one embodiment of this utility model, the walking limit switch is disposed on the side of the track, and the stop mechanism is disposed at the outer end of the top surface of the track and is away from the platform basket relative to the walking limit switch.

[0013] In one embodiment of this utility model, the stop mechanism includes a buffer rubber block.

[0014] In one embodiment of this utility model, the driving device includes a geared motor.

[0015] In one embodiment of this utility model, a motor tail shaft for manual operation is provided at the rear end of the geared motor.

[0016] In one embodiment of this utility model, the platform basket includes a platform base plate and platform side baskets, two sets of opposing platform main baskets, and a door assembly respectively surrounding and installed on the platform base plate. The platform side baskets and the door assembly are arranged opposite to each other. One end of the door assembly is hinged to one set of the platform main baskets, and the other end can be locked to the other set of the platform main baskets by a locking pin assembly.

[0017] In one embodiment of this utility model, a hinge is provided between one end of the door assembly and the side end of one of the main basket pieces of the platform, and the hinge limits the opening direction of the door assembly to opening from the outside to the inside.

[0018] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: This utility model discloses a roof-mounted track-type movable platform. The walking mechanism is equipped with both traveling wheels and anti-tilt wheels. The former rolls in contact with the top surface of the track, while the latter rests against the side of the track, providing bidirectional limiting support during platform movement and significantly improving safety and anti-tipping performance. By installing limit bumpers and stop mechanisms on the track, and configuring travel limit switches on the walking mechanism, the travel limit switches can promptly trigger a stop when the platform basket moves to the end position. Even if the travel limit switches or control circuitry fail, the stop mechanism at the track end can still prevent the platform from going off the track, thus avoiding the risk of derailment and improving overall operational reliability. Dual redundancy of electrical and mechanical limits can be achieved, ensuring that the platform will not overshoot the end due to inertia or misoperation. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0028] In this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0029] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0030] Reference Figure 1 As shown, this utility model discloses a roof-mounted track-type movable platform connected to track 6, comprising: Platform basket 1; The walking mechanism 2 is connected to the platform basket 1. The walking mechanism 2 includes a walking wheel 21 that rolls in contact with the top surface of the track 6, an anti-tilt wheel 22 that is close to the two sides of the track 6, and a driving device 23 that drives the walking wheel 21 to rotate. The travel limit switch 3 is connected to the travel mechanism 2; A limit stop bar 4 is installed on the track 6, and the walking limit switch 3 can contact the limit stop bar 4 when it moves with the platform basket 1; A stop mechanism 5 is provided on the track 6, and the platform basket 1 can contact the stop mechanism 5 when it moves.

[0031] By setting a limit stop bar 4 and a stop mechanism 5 on the track 6, and configuring a travel limit switch 3 on the travel mechanism 2, the travel limit switch 3 can trigger the stop in time when the platform basket 1 moves to the end position; even if the travel limit switch 3 or the control circuit fails, the stop mechanism 5 at the end of the track 6 can still prevent the platform from going off the track 6, thereby avoiding the risk of derailment and improving the overall operational reliability.

[0032] In one embodiment, refer to Figure 5 As shown, the track 6 has two parallel lines, and the walking mechanism 2 has two sets at both ends of the bottom length direction of the platform basket 1. The walking limit switches 3 on the two sets of walking mechanisms 2 are respectively set on both sides of the platform basket 1 along the width direction.

[0033] In one embodiment, refer to Figure 2 , Figure 3 As shown, the walking mechanism 2 includes connecting seats 24 connected to both ends of the platform basket 1 in the width direction and brackets 25 connected to each connecting seat 24. The walking wheel 21 is rotatably connected to the connecting seat 24. The driving device 23 is connected to the connecting seat 24 and its driving end is connected to the walking wheel 21. Two anti-tilt wheels 22 are connected to the brackets 25. The axis of the anti-tilt wheel 22 is perpendicular to the axis of the walking wheel 21, forming a stable three-dimensional anti-overturning structure, so that the platform can still maintain stable operation under wind disturbance, off-center load or local stress.

[0034] Specifically, the walking limit switch 3 is connected to the bracket 25.

[0035] Specifically, the walking limit switch 3 is disposed on the side of the track 6, and the stop mechanism 5 is disposed at the outer end of the top surface of the track 6 and is away from the platform basket 1 relative to the walking limit switch 3.

[0036] In one embodiment, the stop mechanism 5 includes a buffer rubber block.

[0037] The travel limit switches 3 are located on both sides of the platform in the width direction, corresponding to the limit bumpers 4 on the track 6. They can trigger a stop signal in time when the platform approaches the end on either side. Combined with the rigid stop at the end of the track 6, dual redundancy of electrical and mechanical limits can be achieved to ensure that the platform will not rush out of the end due to inertia or misoperation.

[0038] In one embodiment, refer to Figure 3 As shown, the drive device 23 includes a geared motor 231.

[0039] In addition, a motor tail shaft 232 is installed at the rear end of the geared motor 231. In the event of a power outage or other emergency, the operator can manually drive the mobile platform to a safe position by rotating the motor tail shaft 232 with a handwheel or wrench, ensuring the safety of the equipment and personnel.

[0040] In one embodiment, refer to Figure 1 , Figure 2 As shown, the platform basket 1 includes a platform base plate 11, platform side baskets 12, two sets of opposing platform main baskets 13, and a door assembly 14, all mounted on the platform base plate 11. The platform side baskets 12 and the door assembly 14 are arranged opposite each other. One end of the door assembly 14 is hinged to one set of platform main baskets 13, and the other end can be locked to the other set of platform main baskets 13 by a locking pin assembly 15. The platform side baskets 12, platform main baskets 13, platform base plate 11, and door assembly 14 are assembled by bolts. The platform basket 1 is made entirely of aluminum alloy, which is lightweight, corrosion-resistant, and high-strength, thus reducing the stress on the walking mechanism 2 and the track 6.

[0041] In one embodiment, refer to Figure 1 As shown, a hinge 16 is provided between one end of the door assembly 14 and the side end of one of the main platform baskets 13. The hinge 16 limits the opening direction of the door assembly 14 to opening from the outside to the inside. By limiting the opening direction of the door assembly 14 to opening from the outside to the inside, it can effectively prevent the door from opening outwards due to workers accidentally pressing their bodies against the guardrail during operation, thereby avoiding safety accidents.

[0042] During installation, the track 6 is mounted on the roof structural beam of the building or structure. Limiting rods 4 and stop mechanisms 5 are installed on the track 6 to limit the travel range of the mobile platform and improve operational safety. The traveling mechanism 2 is installed above the track 6, and a travel limit switch 3 is installed on the traveling mechanism 2 to trigger a stop signal when it reaches the extreme position. The platform basket 1 spans the two tracks 6, and its ends are connected to the crossbeams of each traveling mechanism 2 by bolts. Each traveling mechanism 2 corresponding to each track 6 is equipped with a geared motor 231 for synchronous drive.

[0043] During operation, the operator enters the mobile platform from the side of the platform basket 1 through the door assembly 14. The operator controls two geared motors 231 to run synchronously via the control box, driving the platform basket 1 to move smoothly along the track 6. When the platform basket 1 moves close to the end of the track 6, the travel limit switch 3 touches the limit stop bar 4, and the mobile platform control system receives a stop signal accordingly, stopping the platform from continuing to move towards the end of the track 6.

[0044] If the travel limit switch 3 or the control circuit malfunctions, causing the limit switch to touch the limit stop rod 4 and still fail to stop the operation, the stop mechanism 5 at the end of the track 6 can effectively prevent the platform basket 1 from going off the track 6, avoiding a derailment accident. At the same time, the rubber block set on the stop mechanism 5 can provide a buffering effect, reducing rigid collisions and preventing equipment damage.

[0045] In the event of a power outage or other emergency, the operator can manually drive the mobile platform to a safe position by rotating the motor tail shaft 232 with a handwheel or wrench, ensuring the safety of the equipment and personnel.

[0046] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
