[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figs. 1-3 In this embodiment of the utility model, an elevator maintenance anti-fall bar includes an anti-fall railing assembly 1 placed inside the elevator entrance 3 of a building. The anti-fall railing assembly 1 intercepts the entrance of the elevator entrance 3. The anti-fall railing assembly 1 includes a concave frame 101, a front stop 102, and a vertical pole 103. The front stop 102 is symmetrically fixed on both sides of the concave frame 101. Multiple sets of concave frames 101 and front stop 102 are arranged vertically. The vertical pole 103 is fixed between two adjacent concave frames 101.

[0027] The concave frame 101 has square slots 104 on both sides, and a fixing seat 105 is fixed in the middle of the concave frame 101. The concave frame 101 is equipped with a fastening component 2 through the square slots 104 and the fixing seat 105. The fastening component 2 includes a pressing unit and a locking unit. The pressing unit is used to press against the inner wall of the building elevator opening 3 of different widths to realize the installation and fixing of the anti-fall railing component 1. The locking unit is used to lock the pressing state of the pressing unit.

[0028] The clamping unit includes a square moving rod, a clamping plate 202, a two-way screw 203, and a knob 204;

[0029] Two square movable rods are symmetrically distributed on both sides of the concave frame 101 and are horizontally slidably connected to the square slot 104. The clamping plate 202 is fixed to the side of the square movable rod away from the concave frame 101.

[0030] The bidirectional screw 203 is rotatably connected to the fixed base 105 and extends to the inside of the two square moving rods. The fixed base 105 has a through hole 106 for the bidirectional screw 203 to pass through. The bidirectional screw 203 is threadedly connected to the square moving rods. The knob 204 is symmetrically fixed to the outside of the bidirectional screw 203 with the fixed base 105 as the center and fits against the side of the fixed base 105.

[0031] The two outer walls of the bidirectional screw 203 are formed with two external threads in opposite directions. The two square moving rods are formed with internal thread holes that match the external threads of the bidirectional screw 203. The bidirectional screw 203 is rotated by the knob 204 to move the two clamping plates 202 away from or closer to each other. The clamping plates 202 are tightly fitted to the inner wall of the building elevator entrance 3 to fix the anti-fall railing assembly 1.

[0032] The locking unit includes a positioning hole 205 and a U-lock 206;

[0033] Multiple positioning holes 205 are evenly arranged in a ring around the bidirectional screw 203, and the multiple positioning holes 205 completely penetrate from one side of the knob 204 to the other side of the knob 204.

[0034] A locking hole 107 is provided on the side of the fixing base 105 below the through hole 106, and the locking hole 107 completely extends to the other side of the fixing base 105.

[0035] When a positioning hole 205 is aligned with a locking hole 107, a U-lock 206 passes through the positioning hole 205 and the locking hole 107 in sequence and locks it to achieve rotational locking of the bidirectional screw 203.

[0036] In this embodiment, the method of using this elevator maintenance fall arrestor is as follows:

[0037] First, move the entire device to the elevator entrance 3 of the building to be protected, and place the entire anti-fall railing assembly 1 inside the elevator entrance 3, with its front guard 102 attached to the outer wall of the elevator entrance 3 (it should be noted that at this time, the two clamping plates 202 of the fastening assembly 2 are close to each other, and the distance between the two clamping plates 202 is less than the width of the elevator entrance 3, which will not affect the placement of the anti-fall railing assembly 1).

[0038] Then, manually rotate the knob 204. The knob 204 drives the bidirectional screw 203 to rotate, so that the two square moving rods 201 move away from each other synchronously. Finally, the two clamping plates 202 are tightly attached to the inner wall of the building elevator entrance 3. Through the friction between the clamping plates 202 and the inner wall of the building elevator entrance 3, the relative fixation of the fall arrest railing assembly 1 and the building elevator entrance 3 can be achieved.

[0039] It should be noted that: a rubber layer is bonded to the side of the clamping plate 202 near the inner wall of the building elevator entrance 3. The rubber layer has a certain shrinkage space and a sufficiently large frictional resistance to ensure the stability of the anti-fall railing assembly 1.

[0040] When the clamping plate 202 is tightly fitted to the inner wall of the building elevator entrance 3, observe whether one of the positioning holes 205 is aligned with the locking hole 107. If they are not aligned, the knob 204 can be finely adjusted (it should be noted that this fine adjustment is a tightening fine adjustment, and the shrinkage performance of the rubber layer can accommodate this fine adjustment) to make one of the positioning holes 205 aligned with the locking hole 107. Then, the U-lock 206 passes through the positioning hole 205, the locking hole 107 and completely through the two knobs 204. After locking the U-lock 206, the rotation of the bidirectional screw 203 can be locked. This not only locks the clamping plate 202 to a state of tight fit with the inner wall of the building elevator entrance 3, but also prevents non-maintenance personnel from disassembling it.

[0041] By using the anti-fall railing assembly 1 to intercept and protect the inside of the building elevator entrance 3, it is possible to effectively prevent non-maintenance personnel from accidentally entering the elevator entrance during elevator maintenance and causing a fall into the shaft, thereby further improving the safety protection effect during elevator maintenance.

[0042] Please refer to this carefully. Figs. 1-3 The square slot 104, the fixing seat 105, and the fastening assembly 2 are arranged in multiple sets along the vertical direction.

[0043] In this embodiment, the connection between the fall arrestor railing assembly 1 and the inner wall of the building elevator entrance 3 can be further improved by the structure of multiple fastening components 2, thereby ensuring the stability of the protective effect.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
