The above-mentioned scheme solves the problem in the prior art that if a maintenance worker causes a fall, the safety rope wrapped around the maintenance worker provides safety protection, but at the same time, the impact force generated when the maintenance worker falls can be converted into a pulling force when the maintenance worker is pulled by the safety rope when falling, thereby causing personal injury to the maintenance worker. It can be understood that the above-mentioned scheme can be used in the case where it is necessary to buffer the impact force generated when falling.

[0023] In this embodiment, the support rod 102 is arranged between the two mounting frames 101. The maintenance personnel can wrap one end of the safety rope around the center of the support rod 102 and wrap the other end of the safety rope around themselves. At the same time, the mounting frame 101 is fixed at the elevator entrance, thereby facilitating the maintenance personnel to go down to the elevator shaft to perform maintenance work.

[0024] The fixing frame 103 is fixedly connected to the mounting frame 101 and is located on one side of the mounting frame 101. The connecting slider 104 is slidably connected to the fixing frame 103 and is fixedly connected to the support rod 102 and is located on a side of the fixing frame 103 close to the support rod 102. The damping connecting rod 105 is respectively connected to the fixing frame 103 and the connecting slider 104 and is located on a side of the fixing frame 103 close to the connecting slider 104. The buffer spring 106 is respectively connected to the fixing frame 103 and the connecting slider 104 through the connecting member. The buffer spring 106 is located on a side of the fixing frame 103 close to the connecting slider 104. The connecting member is arranged on the fixing frame 103. The fixing frame 103 and the connecting slider 104 are connected to the buffer spring 106. The fixing member is arranged on the mounting frame 101. There are two fixing frames 103. The two fixing frames 103 are welded to the corresponding two mounting frames 101. The connection support of the fixing frame 103 is realized by the mounting frame 101. There are two connecting sliders 104. The two connecting sliders 104 are slidably connected in the slide grooves of the corresponding two fixing frames 103. The fixing frame 103 can connect, support and directional limit the sliding of the connecting slider 104. There are two damping connecting rods 105.

There are two buffer springs 106. The two buffer springs 106 are connected and fixed between the fixing frame 103 and the connecting slider 104 through the connecting member. The elastic deformation capacity of the buffer springs 106 can buffer the impact force received by the adjusting slider 110. The connecting member is arranged on the fixing frame 103 and the connecting slider 104 and is connected to the buffer springs 106. The two ends of the buffer springs 106 can be connected and fixed to the connecting slider 104 and the fixing frame 103 through the connecting member. The fixing member is arranged on the mounting frame 101. The mounting member can be fixed to the fixing frame 101 through the fixing member.

At the same time, the impact force generated by the maintenance personnel falling can be transmitted to the connecting slider 104 through the safety rope and the support rod 102, so that the connecting slider 104 moves downward rapidly. The rapid downward movement of the connecting slider 104 compresses the damping connecting rod 105 and the buffer spring 106, so that the impact force transmitted by the safety rope and the support rod 102 can be buffered by the damping characteristics of the damping connecting rod 105 and the elastic deformation capacity of the buffer spring 106, thereby preventing the impact force from directly acting on the maintenance personnel around whom the other end of the safety rope is wrapped.This prevents the maintenance personnel from being injured by the tension caused by the safety rope when they are falling.

[0025] Secondly, the first connecting seat 108 is fixedly connected to the fixing frame 103 and the buffer spring 106 respectively, and the first connecting seat 108 is located on the side of the fixing frame 103 close to the buffer spring 106; the second connecting seat 109 is fixedly connected to the connecting slider 104 and the buffer spring 106 respectively, and the second connecting seat 109 is located on the side of the connecting slider 104 close to the buffer spring 106.

There are two second connecting seats 109, and the two second connecting seats 109 are welded on the other end of the corresponding two connecting sliders 104 and the corresponding two buffer springs 106, and the other end of the buffer spring 106 can be connected and fixed to the connecting slider 104 through the second connecting seat 109.

[0026] At the same time, the adjusting slider 110 is slidably connected to the mounting frame 101 and is located on one side of the mounting frame 101; the first abutting plate 111 is fixedly connected to the adjusting slider 110 and is located on one side of the adjusting slider 110; the second abutting plate 112 is fixedly connected to the first abutting plate 111 and is located on one side of the first abutting plate 111. There are two adjusting sliders 110, and the two adjusting sliders 110 are slidably connected in the corresponding two mounting frames 101. The mounting frame 101 has a slide groove, and there are two first abutting plates 111. The first abutment plates 111 are welded to the corresponding two adjusting sliders 110, and there are two second abutment plates 112. The two second abutment plates 112 are welded to the corresponding two first abutment plates 111. By adjusting and sliding the adjusting slider 110, the operator can adjust the positions of the first abutment plates 111 and the second abutment plates 112 according to the size of the elevator door frame, so as to facilitate the abutment and fixation of the first abutment plates 111 and the second abutment plates 112 on both sides of the elevator entrance, so that the entire device can be abutted and fixed at the elevator entrance.

The blocking frames 107 can limit and block the left and right movement of the safety rope wrapped around the two support rods 102, thereby preventing the winding position of the safety rope from deviating from the center position of the support rod 102 and affecting the buffering effect of the two buffer springs 106 and the two damping connecting rods 105.

[0028] When using the elevator maintenance anti-fall device of the present embodiment, if the maintenance personnel falls, the safety rope wrapped around the maintenance personnel provides safety protection. At the same time, the impact force generated when the maintenance personnel falls can be transmitted to the connecting slider 104 through the safety rope and the support rod 102, so that the connecting slider 104 moves downward rapidly. The rapid downward movement of the connecting slider 104 compresses the damping connecting rod 105 and the buffer spring 106, so that the impact force transmitted by the safety rope and the support rod 102 can be buffered by the damping characteristics of the damping connecting rod 105 and the elastic deformation ability of the buffer spring 106, thereby avoiding the impact force directly acting on the maintenance personnel wrapped around the other end of the safety rope, thereby avoiding the maintenance personnel from being injured by the pulling force when the maintenance personnel is pulled by the safety rope when falling.
