[0022] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] An embodiment of the present utility model discloses a sling removal device for a suspension bridge.

[0024] Referring to Figures 1-3 , a sling removal device for a suspension bridge includes a base 1 and a first housing 2. The first housing 2 is fixedly arranged on one side of the upper surface of the base 1. A second housing 3 is fixedly arranged on one side of the first housing 2. A slide block 4 is slidably arranged inside the first housing 2. One side of the slide block 4 away from the second housing 3 is fixedly provided with a first spring 12, and the other end of the first spring 12 is fixedly connected to the inner wall of the first housing 2. The longitudinal sections of the slide block 4 and the first housing 2 are both rectangular, so that the slide block 4 cannot rotate, that is, it can slide stably. One side of the slide block 4 away from the spring is fixedly provided with a movable rod 5. One end of the movable rod 5 extends to the outside of the second housing 3. One end of the movable rod 5 away from the stopper 18 is fixedly provided with a first mounting plate 15. One side of the first mounting plate 15 abuts against a second mounting plate 16. One side of the second mounting plate 16 away from the first mounting plate 15 is fixedly provided with a knocking rod 14. A vertical rod 10 is fixedly arranged on the upper side of the first housing 2. The upper end of the vertical rod 10 is fixedly provided with a handle 11, which is convenient for holding the device.

[0025] Referring to Figures 1-3, a transmission mechanism for driving the movement of the movable rod 5 is arranged inside the second housing 3. The transmission mechanism includes a rack 6 and an incomplete gear 8. The rack 6 is fixedly arranged on the upper side of the movable rod 5. A rotating rod 7 is rotatably arranged on the upper side inside the second housing 3. A cam 9 is fixedly sleeved on the rod wall of the rotating rod 7. The incomplete gear 8 is fixedly arranged on the lower side of the cam 9. The incomplete gear 8 is meshed and connected with the cam 9. A motor 13 is fixedly arranged on the front side of the second housing 3. The output end of the motor 13 is fixedly connected with one end of the rotating rod 7.

[0026] Referring to Figures 1-3 , a connecting mechanism is arranged between the first mounting plate 15 and the second mounting plate 16. The first mounting plate 15 and the second mounting plate 16 are fixedly connected through the connecting mechanism. The connecting mechanism includes a stop block 18 and a clamping block 20. Insertion holes are opened at both ends of the first mounting plate 15. Plug rods 17 are fixedly arranged at both ends of the side of the second mounting plate 16 close to the first mounting plate 15. Both side plug rods 17 are inserted into the corresponding insertion holes. A cavity is opened inside one end of the plug rod 17 away from the second mounting plate 16. The stop block 18 is slidably arranged inside the cavity. The clamping block 20 is fixedly arranged on one side of the stop block 18. One end of the clamping block 20 extends to the outside of the cavity. The outer end of the clamping block 20 abuts against the side of the first mounting plate 15 away from the second mounting plate 16. A second spring 19 is fixedly arranged on the side of the stop block 18 away from the clamping block 20. The other end of the second spring 19 is fixedly connected with the inner wall of the cavity. The cross sections of the stop block 18 and the cavity are both rectangular, so that the stop block 18 cannot rotate, that is, it can slide stably.

[0027] In the present utility model, during use, the motor 13 drives the cam 9 to rotate, so that the incomplete gear 8 rotates. The incomplete gear 8 drives the rack 6 to move, that is, the slider 4 compresses the first spring 12. When the incomplete gear 8 is separated from the rack 6, the elastic force of the first spring 12 is released, pushing the movable rod 5 to quickly reset, that is, the knocking rod 14 quickly knocks the pin of the sling. By repeating the above actions, the pins of the sling can be automatically removed, which can save manpower and improve work efficiency. When removing pins of different sizes, the clamping block 20 is pushed into the cavity, that is, the limit between the plug rod 17 and the insertion hole can be released, and the first mounting plate 15 and the second mounting plate 16 can be separated, which is convenient for replacing the knocking rod 14 with different diameters.

[0028] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
