[0010] The utility model has the following beneficial technical effects:
[0011] 1. When fixing the elevator, the staff inserts the insertion plate at the bottom of the mounting seat into the card hole of the elevator, and rotates the worm through the turning handle connected to the worm, and drives the bidirectional lead screw to rotate through the transmission of the worm and the worm wheel. Since the connecting plate is threadedly connected to the bidirectional lead screw, and the connecting plate is restricted to move in the left and right directions by the square through hole, the rotating bidirectional lead screw can drive the two connecting plates to move in the opposite direction synchronously, and then drive the clamping plate connected to the connecting plate to move in the opposite direction, so that the two closed clamping plates clamp the elevator guide rail, thereby fixing the elevator, which is easy to operate. Due to the structural characteristics of the worm and worm wheel, the worm is usually used as the active part, and the worm wheel is difficult to drive the worm to rotate. Therefore, after completing the fixing operation, the positions of the two clamping plates are relatively stable and the fixing effect is good.
[0012] 2. The locking assembly limits the rotation ability of the gear, thereby limiting the rotation ability of the bidirectional lead screw or worm connected to the gear, avoiding the movement of the clamping plate caused by the rotation of the bidirectional lead screw and the transmission of the connecting plate, thereby stabilizing the position of the two clamping plates after the fixing operation is completed, and further ensuring the fixing effect.
[0013] 3. The insertion plate and the bottom of the mounting base are detachably connected, which makes it convenient for the staff to replace the damaged insertion plate and allow the mounting base to be smoothly connected to the top of the elevator. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Example:
[0023] like Figures 1 to 5As shown, this embodiment provides a special elevator maintenance and anti-falling fixing fixture, including a mounting seat 1, a bidirectional screw 2 is rotatably connected along the left and right directions in the mounting seat 1, a pair of connecting plates 3 are symmetrically arranged on the bidirectional screw 2, and a threaded cavity 4 is provided on the connecting plate 3 which is threadedly connected to the bidirectional screw 2. A square through hole 5 along the left and right directions is provided on the front side of the mounting seat 1 for the front end of the connecting plate 3 to pass through the mounting seat 1, a clamping plate 6 is provided at the front end of the connecting plate 3, a worm gear 7 is provided in the middle of the bidirectional screw 2, a worm 8 is rotatably connected in the mounting seat 1, the worm 8 is meshed with the worm gear 7, the rotating shaft ends of the bidirectional screw 2 and the worm 8 pass through the mounting seat 1, a turning handle 9 is coaxially connected to the rear end of the rotating shaft of the worm 8, and gears 10 are sleeved on the outer parts of the rotating shaft ends of the bidirectional screw 2 and the worm 8, a locking assembly 11 is provided on the top of the mounting seat 1, and the locking assembly 11 can lock the gears 10 on the rotating shaft ends of the bidirectional screw 2 and the worm 8, and an insertion plate 12 is detachably connected to the bottom of the mounting seat 1.
[0024] When fixing the elevator, the staff inserts the insertion plate 12 at the bottom of the mounting seat 1 into the card hole of the elevator, and rotates the worm 8 through the turning handle 9 connected to the worm 8, and drives the bidirectional screw 2 to rotate through the transmission of the worm 8 and the worm wheel 7. Since the connecting plate 3 is threadedly connected to the bidirectional screw 2, and the connecting plate 3 is restricted by the square through hole 5 to move in the left and right directions, the rotating bidirectional screw 2 can drive the two connecting plates 3 to move in the opposite direction synchronously, and then drive the clamping plate 6 connected to the connecting plate 3 to move in the opposite direction, so that the two closed clamping plates 6 clamp the elevator guide rail, thereby fixing the elevator, which is easy to operate. Due to the structural characteristics of the worm 8 and the worm wheel 7, the worm 8 is usually used as the active part, and the worm wheel 7 is difficult to drive the worm 8 to rotate. Therefore, after completing the fixing operation, the positions of the two clamping plates 6 are relatively stable and the fixing effect is good. The locking assembly 11 limits the rotational capacity of the gear 10, thereby limiting the rotational capacity of the bidirectional screw 2 or the worm 8 connected to the gear 10, avoiding the movement of the clamping plate 6 caused by the rotation of the bidirectional screw 2 and the transmission of the connecting plate 3, thereby stabilizing the positions of the two clamping plates 6 after the fixing operation is completed, further ensuring the fixing effect. The insertion plate 12 is detachably connected to the bottom of the mounting seat 1, which is convenient for the staff to replace the damaged insertion plate 12, so that the mounting seat 1 can be smoothly connected to the top of the elevator.
[0025] Furthermore, the locking assembly 11 includes a turning handle 9, a threaded rod 13, a rotating groove 14, a rotating block 15, an L-shaped plate 16 and a locking block 17. A threaded groove 18 is provided at the top of the mounting seat 1 in the vertical direction. The threaded groove 18 is threadedly connected with the threaded rod 13. The top of the threaded rod 13 is coaxially connected with the rotating groove 14. The rotating block 15 is rotatably connected to the rotating groove 14. The side wall of the rotating block 15 is connected with an L-shaped plate 16. The end of the horizontal part of the L-shaped plate 16 is connected to the rotating block 15. The end of the vertical part of the L-shaped plate 16 is provided with a locking block 17. The side wall of the mounting seat 1 is provided with a limiting groove 26 in the vertical direction pointing to each gear 10 respectively. The vertical part of the L-shaped plate 16 is inserted into the limiting groove 26. The vertical part of the L-shaped plate 16 can move along the limiting groove 26. Each locking block 17 can be synchronously clamped on the corresponding gear 10. The top of the rotating groove 14 is coaxially connected with the turning handle 9.
[0026] The staff member turns the rotating groove 14 connected to the rotating handle 9 and the threaded rod 13 connected to the rotating groove 14 through the rotating handle 9, and the rotating threaded rod 13 moves up and down along the threaded groove 18, and the rotating groove 14 on the threaded rod 13 also moves up and down accordingly, and the height of the L-shaped plate 16 connected to the rotating groove 14 also changes, thereby changing the height of the locking block 17 located at the end of the vertical part of the L-shaped plate 16. By changing the height of the locking block 17, it is controlled whether the locking block 17 is stuck on its corresponding gear 10 to limit the rotation ability of the gear 10.
[0027] Furthermore, a slider A19 is provided at the rear end of the connecting plate 3, a slideway A20 is provided along the left-right direction on the rear inner wall of the mounting seat 1, the slider A19 is slidably connected to the slideway A20, a slider B21 is provided at the end of the clamping plate 6 facing the mounting seat 1 away from the connection of the connecting plate 3, a slideway B22 is provided along the left-right direction on the front of the mounting seat 1, and the slider B21 is slidably connected to the slideway B22. The slider A19 and the slideway A20, the slider B21 and the slideway B22 improve the stability of the translational movement of the clamping plate 6 and the connecting plate 3.
[0028] Furthermore, an anti-skid layer 23 is provided on the facing surfaces of the two clamping plates 6. The anti-skid layer 23 increases the friction between the clamping plates 6 and the elevator guide rails, thereby improving the fixing effect on the elevator.
[0029] Furthermore, the number of the insertion plates 12 is three, and corresponding screw holes 24 are provided at the bottom of the insertion plates 12 and the mounting seat 1 . The detachable connection between the insertion plates 12 and the bottom of the mounting seat 1 is achieved by screwing fixing screws 25 into the overlapping screw holes 24 .
[0030] The working principle and use process of this utility model:
[0031] When the elevator needs to be fixed, the staff first inserts the insertion plate 12 into the clamping hole on the top of the elevator, places the elevator guide rail between the two clamping plates 6, and turns the turning handle 9 connected to the worm 8. After the transmission of the worm 8, the worm wheel 7, the two-way screw 2, and the connecting plate 3, the two clamping plates 6 move toward each other to clamp the elevator guide rail. The staff then turns the turning handle 9 connected to the rotating groove 14, and lets each locking block 17 drop to the corresponding gear 10 on the clamp, restricting the rotation ability of the two-way screw 2 and the worm 8, and completing the elevator fixation. When the elevator needs to be released, the staff first raises each locking block 17 to release the restriction on the gear 10, and then lets the two clamping plates 6 move away from each other to unlock the clamping of the elevator guide rail, thereby releasing the fixation of the elevator, and finally pulls the insertion plate 12 out of the clamping hole on the top of the elevator.

Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
