When this emergency stop alarm threshold is reached, the displacement sensor 7 will send an emergency stop signal to the elevator car, triggering the emergency stop operation of the elevator car). When the external force is released, the linkage detection part 71 will be restored to the horizontal horizontal position due to the action of the reset pad. The reset pad can be made of elastic rubber and other materials (it can meet the elasticity to cope with the up and down movement. After the external force drive is released, the reset pad can make the linkage detection part 71 return to the horizontal horizontal position. Materials that meet the above conditions can be used to manufacture the reset pad).

[0028] like Figure 1 As shown, the defect detection and protection device 40 includes a fixed beam 1 and an L-shaped rotating arm 2. The first end of the L-shaped rotating arm 2 (according to Figure 1 The first end of the L-shaped rotating arm 2 is the left end of the L-shaped rotating arm 2) and is rotatably connected to the first end of the fixed beam 1 (according to Figure 1The first end of the fixed beam 1 is the left end of the fixed beam 1), and the second end of the L-shaped rotating arm 2 (according to Figure 1 The second end of the L-shaped arm 2 is the right end of the L-shaped arm 2) and a roller assembly 10 is rotatably mounted at the bottom. A spring 3 is connected between the top side of the L-shaped arm 2 and the bottom side of the fixed beam 1. The top of the second end of the L-shaped arm 2 is connected to a collision bow mounting column 4. The displacement sensor 7 is fixed to the second end of the fixed beam 1 (according to Figure 1 The second end of the fixed beam 1 is the right end of the fixed beam 1), a trigger 6 is installed at the end of the linkage detection part 71, and a striker assembly 5 corresponding to the trigger 6 is installed on the striker mounting column 4.

[0029] like Figure 1 As shown, the striking bow assembly 5 includes two striking bow units (the striking bow assembly 5 may include only one or more striking bow units, one striking bow unit may be arranged above or below the trigger 6, and multiple striking bow units are arranged around the trigger 6; of course, when the striking bow assembly 5 is a single striking bow unit, the striking bow unit has a clamp-type striking bow 51 corresponding to the trigger 6), the two striking bow units are connected to the striking bow mounting column 4 up and down, and the trigger 6 is cooperatively located between the two striking bow units. Preferably, each striking bow unit has a striking bow 51 corresponding to the trigger 6.

[0031] like Figure 1 As shown, the L-shaped arm 2 is composed of a vertical portion and a transverse portion to form an "L" shape. The vertical portion of the L-shaped arm 2 is rotatably connected to the first end of the fixed beam 1 through a rotating shaft 211, and the transverse portion of the L-shaped arm 2 is located parallel to and below the fixed beam 1. The spring 3 is connected between the fixed beam 1 and the transverse portion of the L-shaped arm 2.

The roller assembly 10 includes a wheel axle 101 and a travel roller 102, and the travel roller 102 is rotatably mounted on the roller mounting frame 221 through the wheel axle 101.

[0033] like Figure 1 As shown, a limit screw 8 is installed on the fixed beam 1, and the spring 3 is assembled outside the limit screw 8, see Figure 1 , the bottom end of the limit screw 8 is at a certain distance from the spring seat 9, and the distance is a limiting distance, which limits the maximum upward rotation distance of the L-shaped rotating arm 2. Figure 5As shown, the limit screw 8 passes through the fixed beam 1, and the limit screw 8 can be threaded up and down to adjust the limit distance of the end of the limit screw 8; a spring seat 9 matched with the spring 3 is fixed on the L-shaped rotating arm 2.

[0034] The utility model is applicable to a traction-type inclined elevator and is used for detecting in advance the missing or displacement of the main rail or the auxiliary rail of the inclined elevator. When in use, the running roller 102 of the defect detection and protection device 40 runs synchronously on the elevator guide rail. When there is a missing or displaced defect on the elevator guide rail, the running roller 102 will rise or fall, and the collision bow installation column 4 will rise or fall synchronously. The various collision bow units of the collision bow assembly 5 will drive the trigger 6 to rise or fall, and then drive the connecting part 71 to rise or fall, and the displacement sensor 7 of the defect detection and protection device 40 will detect it, and send an emergency stop signal to the elevator car 20 and trigger the elevator emergency stop operation, thereby stopping the elevator car 20 within the effective and safe guide rail range.

[0035] When in use, the device is respectively arranged on the front and rear sides of the elevator car 20 and corresponding to the main rail or the auxiliary rail, that is, one elevator car 20 can correspond to four sets of the device. In the daily working state of the elevator, the running roller 102 of the roller assembly 10 slides normally on the main rail or the auxiliary rail. At this time, the second end of the L-shaped rotating arm 2 is arranged parallel to the second end of the fixed beam 1, the spring 3 is in a natural state, the trigger 6 is horizontally centered between the upper and lower striker units of the striker assembly 5, and no striker unit applies force to the trigger 6.

[0036] Once the main rail or auxiliary rail of the elevator is missing or displaced during the forward movement, the running roller 102 of the roller assembly 10 will sink or lift up, thereby driving the L-shaped rotating arm 2 to rotate around the fixed beam 1. At this time, the impact bow 51 of the impact bow unit on the upper or lower side of the impact bow assembly 5 will touch the trigger 6, and the trigger 6, the connecting part 61, and the linkage detection part 71 will move upward or downward synchronously. The displacement sensor 7 will detect the movement state and movement displacement (the displacement sensor 7 can be set to detect the emergency stop alarm threshold of the displacement size of the up and down movement. When this emergency stop alarm threshold is reached, the displacement sensor 7 will send an emergency stop signal to the elevator car, triggering the emergency stop operation of the elevator car), and at the same time send a signal to the elevator control box to stop the elevator. The function of the spring 3 is to limit the position during the rotation of the L-shaped rotating arm 2, and to reset the L-shaped rotating arm 2 in time after stopping the elevator and solving the guide rail problem.
