[0002] The elevator pit is an important part of the elevator system. It is located at the bottom of the elevator shaft and provides support and shock absorption for the elevator equipment. In order to ensure the normal operation of the elevator and the safety of the passengers, it is very important to perform regular maintenance on the elevator pit.

[0003] With the improvement of national safety awareness, people have attached great importance to the safety performance of elevator pits. During long-term use, the elevator pit needs to be maintained to ensure that the support and shock-absorbing components inside the pit can work normally. However, common elevator pits lack temporary buffering and anti-seismic functions during maintenance, which poses certain risks. However, if anti-seismic components are simply added, it may affect the normal operation of the original anti-seismic components inside the elevator pit, thereby causing certain inconveniences to the maintenance work.

[0025] The utility model provides the following technical solutions: Embodiment 1

[0026] Combination Figures 1 to 4 , a buffer device for elevator pit maintenance, comprising a fixed box 1, an adjusting mechanism 3 is arranged inside the fixed box 1, a support platform 5 is arranged on the top of the adjusting mechanism 3, a buffer 2 is fixedly connected to the top of the support platform 5, and a load-bearing mechanism 4 is arranged on the bottom of the support platform 5;

[0027] The adjusting mechanism 3 includes a threaded rod 31, which is rotatably connected to the inner wall of the fixed box 1, a worm wheel 32 is fixedly connected to the outer wall of the threaded rod 31, a worm 33 is meshed with the outer ring of the worm wheel 32, a connecting frame 34 is threadedly connected to the outer wall of the threaded rod 31, a slider 35 is fixedly connected to the outer side of the connecting frame 34, and a fixing groove 36 is fixedly connected to the inner wall of the fixed box 1.

[0028] Furthermore, the worm 33 is rotatably connected to the left side of the inner wall of the fixed box 1, and the right end of the worm 33 is fixedly connected to a hand wheel 1, so that the worm 33 can be rotated by shaking the hand wheel 1.

[0029] Furthermore, a rotating hole is opened on the right side of the fixed box 1, and the worm 33 is rotatably connected to the inner wall of the rotating hole, thereby achieving the purpose of stably supporting the worm 33.

[0030] Furthermore, the outer shape of the slider 35 matches the inner wall shape of the fixing groove 36 , and the slider 35 is slidably connected to the inner wall of the fixing groove 36 , so as to achieve stable limiting.

[0031] Furthermore, a rectangular opening is opened on the top of the fixed box 1, and the connecting frame 34 passes through the opened rectangular opening. The support platform 5 is fixedly connected to the top of the connecting frame 34, so that the connecting frame 34 can move through the rectangular opening. Embodiment 2

[0032] See also Figures 1 to 4 On the basis of the first embodiment, the load-bearing mechanism 4 further comprises a support block 46, the support block 46 is fixedly connected to the bottom of the support platform 5, the bottom of the support block 46 is fixedly connected to a fixed block 41, the fixed block 41 is rotatably connected to a threaded rod 42 inside, the outer wall of the threaded rod 42 is threadedly connected to a threaded block 43, one side of the threaded block 43 is fixedly connected to a long block 44, and the left side of the fixed box 1 is fixedly connected to a load-bearing block 45, which further improves the stability of the support of the buffer 2.

[0033] Furthermore, a moving opening is opened inside the support block 46 , and the long block 44 passes through the moving opening and moves, so that the long block 44 can move through the moving opening.

[0034] Furthermore, the right end of the second threaded rod 42 is fixedly connected to the second hand wheel, and a rectangular opening is opened on one side of the load-bearing block 45 so that the long block 44 can be inserted into the inner wall of the rectangular opening.

[0035] The worm 33 and the worm wheel 32 are meshed, so that the worm wheel 32 drives the threaded rod 31 to rotate. Since the threaded rod 31 and the connecting frame 34 are threadedly connected, the rotational motion of the threaded rod 31 is converted into the linear motion of the connecting frame 34. The connecting frame 34 can drive the support platform 5 to rise, and the support platform 5 can drive the buffer 2 to rise. At the same time, the slider 35 can slide and limit on the inner wall of the fixed groove 36, so that the working height of the buffer 2 is higher than the height of the original anti-seismic components inside the elevator pit, and the working height of the buffer 2 is also higher than the height of the maintenance personnel. In this way, when the elevator car body falls downward, the buffer 2 can play the role of buffering, reduce the existing safety hazards, and ensure that the components inside the elevator pit can work normally, thereby further improving the safety performance of the device.

[0036] When the support platform 5 drives the buffer 2 to rise, the support block 46 will be driven to move upward. When the height adjustment of the buffer 2 is completed, the long block 44 and the rectangular opening opened by the load-bearing block 45 are in an aligned position. At this time, shaking the hand wheel 2 can drive the threaded rod 2 42 to rotate. Since the threaded rod 2 42 and the threaded block 43 are threadedly connected, the threaded block 43 will drive the long block 44 to be inserted into the rectangular opening of the load-bearing block 45. When the elevator car body falls to the top of the buffer 2, since the long block 44 is inserted into the inside of the load-bearing block 45, the load-bearing block 45, the long block 44 and the load-bearing block 45 can withstand part of the impact force under the cooperation of each other, thereby reducing the situation where the connecting frame 34 is damaged due to excessive impact force, further ensuring the stability of the device during use, and enhancing the practicality of the device.
