A hand-cranked rotary C-shaped track cross turntable system

Abstract

This application relates to a hand-cranked rotary C-shaped track cross turntable system, comprising a cross track, a mounting frame fixed to a building, a rotating track rotatably connected below the mounting frame, and a limiting component for limiting the position of the rotating track. A clearance groove is provided at the intersection of the cross tracks to disconnect them. The mounting frame is disposed within the clearance groove. Both ends of the rotating track can respectively abut against the parallel sidewalls of the clearance grooves of the cross tracks. The limiting component is disposed on the rotating track and can be connected to the mounting frame to limit the position of the rotating track. When a track change is required, the gondola can be moved onto the rotating track. Then, the limiting component no longer limits the rotation of the rotating track, allowing the rotating track to rotate 90 degrees until it aligns with another track of the cross track. The rotating component then limits the rotation of the rotating track, allowing the gondola to be moved back onto the cross track for continued operation.

Description

Technical Field

[0001] This application relates to the technical field of window cleaning machines, and in particular to a hand-cranked rotary C-track cross turntable system. Background Technology

[0002] When cleaning the glass of high-rise buildings, window cleaning machines are usually used. Currently, fixed tracks are usually installed on the building so that the gondola can move on the tracks, which facilitates the continuous cleaning of the glass.

[0003] However, buildings usually have multiple facades, so each facade has a track at the top for the gondola to move on. The tracks are usually straight, and there is an angle between the tracks of adjacent facades, usually 90 degrees. The gondola cannot be transferred to another track by passing through the angle between adjacent tracks, so a gondola needs to be installed on each track, which results in a higher overall cost.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] To enable the gondola to be moved on different tracks, this application provides a hand-cranked rotary C-type track cross turntable system.

[0006] This application provides a hand-cranked rotary C-type track cross turntable system, which adopts the following technical solution:

[0007] A hand-cranked rotary C-shaped track turntable system includes a cross track fixed to a building, a mounting frame fixed to the building, a rotating track rotatably connected to the mounting frame, and a limiting component for limiting the position of the rotating track. The cross track has a clearance groove at its intersection to separate it. The mounting frame is disposed within the clearance groove. Both ends of the rotating track can abut against the parallel sidewalls of the clearance groove of the cross track. The limiting component is disposed on the rotating track and can be connected to the mounting frame to limit the position of the rotating track.

[0008] By adopting the above technical solution, when a track change is required, the gondola can be moved to the rotating track. Then, the limiting component no longer limits the rotation of the rotating track, and the rotating track is rotated 90 degrees to align with the other track of the cross track. Then, the rotating component limits the rotation of the rotating track, and the gondola can be moved to the cross track to continue working.

[0009] Optionally: The limiting component includes a limiting rod that is slidably disposed on the rotating track and an elastic element that pushes the limiting rod toward the mounting frame. The mounting frame is provided with a mounting plate, the axis of the mounting plate coincides with the rotation axis of the rotating track, and the mounting plate is provided with a plurality of limiting holes in the circumferential direction. The upper end of the limiting rod can be inserted into the limiting holes so that the rotating track is aligned with the cross track.

[0010] By adopting the above technical solution, the relative rotation between the rotating track and the mounting plate is limited by the cooperation of the limiting rod and the limiting hole on the mounting plate, so that the relative position between the rotating track and the mounting plate is not easily changed. When the rotating track needs to be rotated, the limiting rod can be pulled out from the limiting hole to allow the rotating track to rotate. The limiting and releasing process of the rotating track is more convenient, and the switching process of the gondola on the track is more convenient.

[0011] Optionally, the rotating track is further provided with a drive assembly for rotating it. The drive assembly includes a rotating shaft rotatably connected to the rotating track, a gear coaxially fixed to the rotating shaft, and an internal gear ring coaxially fixed below the mounting plate. The axis of the rotating shaft is parallel to the rotation axis of the rotating track, and the internal gear ring meshes with the gear.

[0012] By adopting the above technical solution, when the rotating track needs to be rotated, the rotating shaft can be rotated to drive the rotating track to rotate. The number of rotations can be used to determine whether the rotating track is aligned with the opening of the clearance groove on the cross track, making it easier to determine the stopping position of the rotating track and making the rotation of the rotating track more convenient.

[0013] Optionally: the limiting rod passes through the rotating shaft and slides with the rotating shaft, and the cross section of the limiting rod perpendicular to the rotating shaft is polygonal.

[0014] By adopting the above technical solution, after the limit rod is moved downward, the rotation of the limit rod can drive the rotation of the rotating shaft, so that both releasing the limit and driving the rotation of the rotating track can be done by moving the limit rod, making the rotation of the rotating track more convenient.

[0015] Optionally: The lower end of the limiting rod is provided with a hanging ring, and a rotating rod is detachably connected to the hanging ring.

[0016] By adopting the above technical solution, the force is transmitted to the limit rod through the rotating rod, thereby driving the rotating shaft to rotate. When applying force, one can stand directly on the gondola to drive the rotating shaft to rotate, making the switching of the gondola's track more convenient.

[0017] Optionally: A hook is provided at the upper end of the rotating rod, and the hook is attached to the hanging ring.

[0018] By adopting the above technical solution, when it is necessary to drive the rotating shaft to rotate, the hook can be connected to the hanging ring, thereby driving the rotating shaft to rotate through the rotating rod. After the adjustment of the rotating track is completed, the force can be divided between the rotating rod and the rotating shaft, so that the rotating rod will not affect the movement of the gondola.

[0019] Optionally: A limiting ring is provided at the lower end of the mounting plate, and the end faces of the cross rails near the clearance groove are all inserted into the limiting ring.

[0020] By adopting the above technical solution, the position of the cross track near the relief groove is limited by the limiting ring, so that the position of the cross track is not easy to wobble. Therefore, after the rotating track rotates, the positions of the two ends of the rotating track are easier to align with the cross track.

[0021] Optionally, the end of the hook away from the rotating rod is also provided with a friction plate, and the hook can be inserted into the cross track and the friction plate can abut against the inner cavity of the cross track.

[0022] By adopting the above technical solution, when it is necessary to move the gondola relative to the cross track or the rotating track, the hook can be inserted into the cross track or the rotating track, and then the gondola can be moved by applying force to the hook.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When a track change is required, the gondola can be moved to the rotating track. Then, the limiting component will no longer limit the rotation of the rotating track. The rotating track will be rotated 90 degrees and aligned with the other track of the cross track. Then, the rotating component will limit the rotation of the rotating track. After that, the gondola can be moved to the cross track to continue working.

[0025] 2. When the rotating track needs to be rotated, the rotating shaft can be rotated to drive the rotating track to rotate. The number of rotations can be used to determine whether the rotating track is aligned with the opening of the clearance groove on the cross track, making it easier to determine the stopping position of the rotating track and making the rotation of the rotating track more convenient.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a hand-cranked rotary C-shaped track cross turntable system, such as Figure 1 and Figure 2 As shown, the system includes a cross track 1 fixed to a building, a mounting frame 2 fixed to the building, a rotating track 3 rotatably connected below the mounting frame 2, and a limiting component 4 for limiting the position of the rotating track 3. Both the cross track 1 and the rotating track 3 are horizontally arranged, and their vertical cross-sections are identical, allowing the gondola to move within them. The cross track 1 has a cross-shaped arrangement, with a clearance groove 11 at the intersection to separate it, resulting in four mutually split tracks. The rotating track 3 is positioned between the four mutually distant tracks of the cross track 1, and it can connect and abut two tracks on the cross track 1 that are aligned in a straight line.

[0032] The mounting bracket 2 is vertically arranged, and a mounting plate 21 is coaxially mounted on its lower end. A drive assembly 5 for rotating the rotating track 3 is located at the lower end of the mounting plate 21. The drive assembly 5 includes a rotating shaft 51 rotatably connected to one side of the rotating track 3, an internal gear ring 52 coaxially fixed to the lower part of the mounting plate 21, and a gear 53 coaxially fixed to the rotating shaft 51. A connecting ring 31 is mounted and fixed on the rotating track 3, with its axis coinciding with the rotating shaft 51. The connecting ring 31 is rotatably connected to the lower part of the mounting plate 21 via a rotating support. The rotating shaft 51 is rotatably connected to the side wall of the rotating track 3 via a bearing. The gear 53 is mounted on the upper end of the rotating shaft 51 and can mesh with the internal gear ring 52. Therefore, when the rotating shaft 51 is rotated, the gear 53 can move along the internal gear ring 52, thereby driving the rotating track 3 to rotate.

[0033] A limiting ring 12 is coaxially mounted on the lower end of the mounting plate 21. The drive assembly 5 is set inside the limiting ring 12. The four rails of the cross rail 1 are threaded through the limiting ring 12 and fixed to the limiting ring 12 at one end near the relief groove 11. This limits the position of the cross rail 1 near the relief groove 11, making it easier for the rotating rail 3 to align the cross rail 1 after rotation.

[0034] like Figure 2 and Figure 3 As shown, the drive assembly 5 is also equipped with a limiting assembly 4 that limits the rotation of the rotating track 3. The limiting assembly 4 includes a limiting rod 41 passing through the rotating shaft 51 and an elastic element 42 that pushes the limiting rod 41 toward the mounting frame 2. The limiting rod 41 is arranged parallel to the axis of the mounting frame 2, and the horizontal cross section of the limiting rod 41 is rectangular. The limiting rod 41 can slide along the axis of the rotating shaft 51 and can also drive the rotating shaft 51 to rotate. Four limiting holes 211 are circumferentially penetrating the upper end surface of the mounting plate 21. The upper end of the limiting rod 41 can be inserted into the limiting holes 211, so that the rotating track 3 can be aligned with the opening at the clearance groove 11 of the cross track 1, so that the gondola can slide from the cross track 1 onto the rotating track 3, or move from the rotating track 3 onto the cross track 1. In this embodiment, the elastic element 42 is a spring. The elastic element 42 is sleeved on the limiting rod 41. The upper end of the gear 53 is coaxially provided with a receiving groove 531. The lower end of the elastic element 42 abuts against the bottom surface of the receiving groove 531. A retaining ring 411 is also coaxially provided on the limiting rod 41. The upper end of the elastic element 42 abuts against the lower end of the retaining ring 411, thereby pushing the limiting rod 41 into the limiting hole 211.

[0035] To facilitate the rotation of the rotating shaft 51, a hanging ring 511 is installed at the lower end of the rotating shaft 51. A rotating rod 54 for driving the rotating ring 511 is connected to the hanging ring 511. A hook 541 is installed at the upper end of the rotating rod 54, which can be hooked onto the hanging ring 511. When standing on the gondola, by connecting the hook 541 to the hanging ring 511, the rotation of the rotating rod 54 can correspondingly drive the rotating shaft 51 to rotate, thereby driving the rotating track 3 to rotate.

[0036] To facilitate the movement of the gondola on the track, a friction plate 542 is provided at the end of the hook 541 away from the rotating rod 54. When it is necessary to move the gondola relative to the rotating track 3 or the cross track 1, the hook 541 can be inserted into the inner cavity of the rotating track 3 or the cross track 1, so that the hook 541 abuts against the bottom wall of the inner cavity of the rotating track 3 or the cross track 1. By applying force to the rotating rod, the gondola can be moved without the hook 541 moving.

[0037] The implementation principle of this embodiment is as follows: When it is necessary to change the track of the gondola, the gondola is lifted upward and brought close to the cross track 1. The hook 541 is inserted into the cross track 1 to drive the gondola to move, so that the gondola is completely moved below the rotating track 3. The hook 541 is hooked onto the hanging ring 511, and pulled downward to make the limiting rod 41 disengage from the limiting hole 211 on the mounting plate 21. Then, the rotating rod 54 drives the rotating shaft 51 to rotate, and the rotating shaft 51 drives the gear 53 to rotate, thereby driving the rotating track 3 and the gondola to rotate. After the rotating track 3 rotates 90 degrees, it is determined whether the rotating track 3 is aligned with the cross track 1. After alignment, the limiting rod 41 is no longer pulled, and the limiting rod 41 moves upward under the push of the elastic member 42 and inserts into the limiting hole 211. If the limiting rod 41 does not move upward, the position of the rotating track 3 is adjusted again until the limiting rod 41 can be inserted into the limiting hole 211. Then, the hook 541 is disengaged from the hanging ring 511, and the gondola is moved to the cross track 1 to work.

[0038] 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.
