Description

Technical Field

[0001] The utility model relates to the field of elevator maintenance, in particular to an elevator maintenance anti-closing bracket. Background Art

[0002] Elevators are a general term for vertical transportation tools within buildings. They can be divided into escalators and elevators according to the driving method. They are a type of transportation tool that transports pedestrians in the form of a conveyor belt. To ensure safety, people need to maintain the elevators regularly. During maintenance, to avoid sudden start-up of the elevator, the elevator doors need to be limited to ensure safety.

[0003] At present, maintenance personnel usually need to turn off the elevator power first, and then use a support rod to hold the inside of the elevator door to prevent the elevator door from suddenly starting and closing. However, this method is relatively dangerous. When the elevator door suddenly starts and closes, the support rod is easy to break, and the safety is low.

[0004] In summary, there is an urgent need for an elevator maintenance anti-closing bracket with higher safety to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will now be described more fully below with reference to the accompanying drawings, in which the present invention is shown in its currently preferred embodiments. However, the present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0025] Embodiment: An elevator maintenance anti-closing bracket, see Figure 1-Figure 7 As shown, it includes a support frame 1, a rotating rod 2, a first gear 21, a second gear 22, a movable plate 3, a rotating disk 4, an anti-skid ring 5, a stop plate 6, a connecting piece 7, a plastic pad 8, a fixed plate 9, a stabilizing plate frame 10, a damping block 11, a connecting block 12, a limit plate 13 and a connecting rod 14. The number of support frames 1 is two. By placing the support frames 1, the elevator door can be prevented from closing. The support frame 1 is rotatably provided with a rotating rod 2 inside, a first gear 21 is welded at the lower part of the rotating rod 2, and the first gear 21 is rotatably connected to the adjacent support frame 1. The support frame 1 is rotatably provided with a rotating disk 4 outside, a second gear 22 is connected to the inner side of the rotating disk 4, the second gear 22 is rotatably connected to the adjacent support frame 1, and the second gear 22 is meshed with the first gear 21. A movable plate 3 is threadedly provided on the rotating rod 2, and the movable plate 3 is slidably connected to the adjacent support frame 1. The handle of the rotating disk 4 is provided with an anti-skid ring 5. The upper part of the movable plate 3 is provided with a screw thread. A butt plate 6 is installed through the connecting piece 7. The butt plate 6 is U-shaped. The butt plate 6 can move upward to resist the top of the elevator door to support the support frame 1. A plastic pad 8 is connected to the butt plate 6. Fixed plates 9 are welded on both sides of the front and rear of the bottom of the support frame 1. A stabilizing plate frame 10 is rotatably arranged between the two corresponding front and rear fixing plates 9. The stabilizing plate frame 10 is used to further firmly support the support frame 1. A damping block 11 is symmetrically connected between the outer wall of the stabilizing plate frame 10 and the adjacent fixing plates 9. The damping block 11 is a circular ring. Connecting blocks 12 are symmetrically welded to the outsides of the two support frames 1. A limiting plate 13 is rotatably arranged on the connecting block 12 on the left support frame 1. The limiting plate 13 is parallel to the connecting block 12 on the right support frame 1. The limiting plate 13 can clamp the two support frames 1 for easy transportation. A connecting rod 14 is threadedly arranged between the connecting block 12 on the right support frame 1 and the adjacent limiting plate 13.

[0026] When the device needs to be used, the maintenance personnel first turn off the power of the elevator, and then rotate the connecting rod 14, so that the connecting rod 14 moves outward to loosen the limit plate 13 and the support frame 1, and then rotate the limit plate 13 downward so that it no longer jams the two support frames 1, and then place the two support frames 1 on the inner sides of the elevator door respectively. The stabilizing plate frame 10 can stably support the support frame 1. At this time, the maintenance personnel can rotate the rotating disk 4, and the rotation of the rotating disk 4 drives the second gear 22 to rotate, and the rotation of the second gear 22 drives the first gear 21 to rotate, and the rotation of the first gear 21 drives the rotating rod 2 to rotate, and the rotation of the rotating rod 2 drives the moving plate 3 and the resisting plate 6 to move upward, so that the elevator can be resisted by the resisting plate 6. The top of the door further supports the support frame 1, and the plastic pad 8 plays a protective role, so as to achieve the purpose of preventing the elevator door from closing and avoiding the elevator door from suddenly starting and closing. The safety is relatively high. After being placed, the maintenance personnel can repair the elevator. When the device is not needed, the rotating disk 4 is reversed to drive the second gear 22 to reverse. The reversal of the second gear 22 drives the first gear 21 and the rotating rod 2 to reverse. The reversal of the rotating rod 2 drives the moving plate 3 and the abutment plate 6 to move downward and reset, and then the two support frames 1 are merged together, and the limit plate 13 is rotated upward and fixed by the connecting rod 14, and then the stabilizing plate frame 10 is rotated upward and retracted, so as to facilitate the storage and transportation of the device.
