[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1

[0030] like Figures 1-5 As shown, this embodiment proposes a cable winch traction machine, including a base plate 1, casters 2 fixedly connected to the top of the base plate 1, a pusher frame 3 fixedly connected to the side of the base plate 1, and a traction device 4 provided on the top of the base plate 1.

[0031] The traction device 4 includes a motor 41, which is mounted above the base plate 1. A support plate 42 is fixedly connected to the top of the motor 41, and the side of the motor 41 is fixedly connected to the side of the support plate 42. A rotating shaft 43 is fixedly connected to the output shaft of the motor 41, and a winch 44 is fixedly connected to the circumferential surface of the rotating shaft 43.

[0032] An extension groove 45 is provided on the top of the base plate 1. A roller 46 is rotatably connected inside the extension groove 45. This design helps to reduce the friction between the cable and the extension groove 45 through the roller 46.

[0033] A limit frame 47 is fixedly connected to the side of the base plate 1. A limit groove 48 is opened on the side of the limit frame 47. A buffer plate 49 is slidably connected to the inner wall of the limit groove 48. This design helps to prevent the traction machine from being damaged by a collision when passing through the buffer plate 49.

[0034] A spring hole 410 is provided on the side of the base plate 1. A spring 411 is fixedly connected to the inner wall of the spring hole 410. The end of the spring 411 away from the spring hole 410 is fixedly connected to the side of the buffer plate 49. This design is conducive to resetting the buffer plate 49 by means of the spring 411.

[0035] The number of rollers 46 is set to several and arranged in a linear array on the inner wall of the extension groove 45. The side of the buffer plate 49 is elastically connected to the inner wall of the spring hole 410 by spring 411. This design is beneficial to reduce the friction between the cable and the extension groove 45 when multiple rollers 46 are used.

[0036] In this embodiment, when cable traction is required, one end of the cable is first wound around the winch 44, and then the motor 41 is started. When the motor 41 starts, the shaft 43 on the output shaft of the motor 41 rotates clockwise. When the shaft 43 rotates clockwise, the winch 44 on the shaft 43 rotates clockwise. When the winch 44 rotates clockwise, the cable on the winch 44 is pulled from left to right. The friction between the cable and the extension groove 45 is reduced by the roller 46. When the shaft 43 rotates counterclockwise, the winch 44 on the shaft 43 rotates counterclockwise. When the winch 44 rotates counterclockwise, the cable on the winch 44 cannot be pulled.

[0037] Example 2

[0038] like Figures 1-5 As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. A fixing device 5 is provided inside the base plate 1. The fixing device 5 includes a support block 51, the bottom of which is fixedly connected to the top of the base plate 1. A rotating shaft 52 is rotatably connected inside the support block 51. A first sprocket 53 is fixedly passed through the circumferential surface of the rotating shaft 53, and a second sprocket 54 is fixedly passed through the circumferential surface of the rotating shaft 52. A chain 55 is provided above the base plate 1. The inner side of the chain 55 meshes with the circumferential surface of the first sprocket 53. The bottom plate 1 has a rack groove 56 on the top of the base plate 1, and a gear 57 is fixedly inserted through the circumference of the rotating shaft 52. A rack 58 is slidably connected to the inner wall of the rack groove 56. The circumference of the gear 57 meshes with the side of the rack 58. A fixing plate 59 is fixedly connected to the bottom of the rack 58. This design is conducive to the rotation of the rotating shaft 52 when the rotating shaft 43 rotates through the transmission of the chain 55. When the rotating shaft 52 rotates, the rack 58 moves through the meshing of the gear 57 and the rack 58, causing the fixing plate 59 to collide with the ground for fixation.

[0039] The bottom of the fixing plate 59 is fixedly connected to the anti-slip plate 510, and the bottom of the anti-slip plate 510 is provided with an anti-slip groove 511. This design helps to prevent the fixing plate 59 from sliding when fixed on a wet ground by using the anti-slip groove 511.

[0040] A fixing bracket 512 is fixedly connected to the side of the base plate 1. A fixing groove 513 is provided on the side of the fixing bracket 512. A fixing block 514 is slidably connected inside the fixing groove 513. This design is conducive to fixing the caster 2 through the fixing block 514 and preventing the caster 2 from moving when it is fixed.

[0041] The number of support blocks 51, rotating shafts 52, chains 55, gears 57, racks 58 and fixing plates 59 is set to two groups, and they are symmetrical to each other along the vertical central axis of the bottom plate 1, which is beneficial to increase the fixing effect through the two groups of fixing plates 59.

[0042] The number of fixing frames 512 and fixing blocks 514 is set to two groups, and they are symmetrical to each other along the vertical central axis of the bottom plate 1, and the fixing blocks 514 are located above the casters 2, which is beneficial to fix the casters 2 through the two groups of fixing blocks 514 to prevent the bottom plate 1 from moving during fixing.

[0043] In the embodiment, when traction is performed, the traction machine needs to be fixed to prevent uneven traction force caused by movement or shaking, which may cause damage to the equipment. First, the motor 41 is started, and when the motor 41 is started, the rotating shaft 43 on the output shaft of the motor 41 rotates clockwise, and when the rotating shaft 43 rotates clockwise, the rotating shaft 43 drives the rotating shaft 52 to rotate clockwise through the transmission of the chain 55, and when the rotating shaft 52 rotates clockwise, the rotating shaft 52 drives the rack 58 to move horizontally downward through the meshing of the gear 57 and the rack 58, and when the rack 58 moves horizontally downward, the fixing plate 59 at the bottom of the rack 58 collides with the ground to fix the traction machine. When it is not necessary to be fixed, the rotating shaft 43 rotates counterclockwise, and when the rotating shaft 43 rotates counterclockwise, the rotating shaft 43 drives the rotating shaft 52 to rotate counterclockwise through the transmission of the chain 55, and when the rotating shaft 52 rotates counterclockwise, the rotating shaft 52 drives the rack 58 to move horizontally upward through the meshing of the gear 57 and the rack 58, and when the rack 58 moves horizontally upward, the fixing plate 59 at the bottom of the rack 58 is away from the ground, and at this time, it cannot be fixed.

[0044] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
