Detailed Implementation

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figures 1-4 As shown, a wheeled tractor rear axle maintenance bracket includes a displacement bracket and a tabletop 5 fixedly connected to the displacement bracket. Two parallel tightening mechanisms are fixedly connected to the upper side of the tabletop 5. Each of the two tightening mechanisms is fixedly connected to a restraining strap 9. The portion of the restraining strap 9 away from the tightening mechanism is detachably fixedly connected to the tabletop 5.

[0020] At this time, when using it, place the rear axle 17 of the tractor to be repaired on the upper side of the tabletop 5, and then pass the two restraint straps 9 around the upper side of the rear axle 17 of the tractor to be repaired and fix them to the tabletop 5. This can fix one end of the restraint straps 9. Then, tighten the other end of the restraint straps 9 through the tightening mechanism to fix the other end of the restraint straps 9. In this way, the rear axle 17 of the tractor to be repaired can be fixed stably on the upper side of the tabletop 5 in a relatively simple way.

[0021] Among them, such as Figures 2-3 As shown, the tightening mechanism includes a housing 6 fixedly connected to the upper side of the tabletop 5. A first screw 7 is rotatably connected inside the housing 6. A movable plate 8 is threadedly connected to the outer side of the first screw 7. The movable plate 8 is vertically slidably connected inside the housing 6, and one end of the movable plate 8 is fixedly connected to the restraint strap 9. By rotating the first screw 7, the movable plate 8 can be moved, which can move the end of the restraint strap 9 to adjust the tightness of the restraint strap 9. The adjustment method is relatively simple, and it has a self-locking function after adjustment.

[0022] like Figures 2-3 As shown, one method of fixing the restraint strap 9 is disclosed here. In this technical solution, a fixing block 11 is installed on the upper side of the tabletop 5. A protruding locking tongue 12 is fixedly connected to the side of the fixing block 11 away from the outer shell 6. The restraint strap 9 has multiple locking grooves 10. The protruding locking tongue 12 can be engaged in any of the locking grooves 10. At this time, the tension of the restraint strap 9 can be adjusted by engaging the protruding locking tongue 12 in the corresponding locking groove 10. Then, by rotating the first screw 7 for fine adjustment, the rear axle 17 of the tractor to be repaired can be fixed relatively easily by the restraint strap 9.

[0023] Specifically, the restraint strap 9 can be a chain, and the locking groove 10 is an opening on the chain.

[0024] like Figures 2-4 As shown, in order to be applicable to different models of tractor rear axles 17 to be repaired, this technical solution has a sliding groove on the tabletop 5, and a slider 15 is slidably connected inside the sliding groove. A fixing block 11 is fixedly connected to the upper side of the slider 15. A second screw 14 is also rotatably connected to the tabletop 5. The second screw 14 and the slider 15 are threadedly connected. By rotating the second screw 14, the slider 15 can be moved to adjust the distance between the fixing block 11 and the outer shell 6 to adapt to the width of different tractor rear axles 17 to be repaired.

[0025] The upper side of the tabletop 5 is also slidably connected to a slide block 16 located between the fixing block 11 and the outer shell 6. By placing the rear axle 17 of the tractor to be repaired on the slide block 16, the tractor rear axle 17 to be repaired can be better fixed with the restraint strap 9.

[0026] Multiple rubber pads 13 are fixedly connected to the lower side of the restraint belt 9. The setting of multiple rubber pads 13 can reduce the wear of the restraint belt 9 on the rear axle 17 of the tractor to be repaired.

[0027] like Figures 1-3 As shown, the displacement bracket includes a base frame 1 and a lower frame 2. Multiple movable wheels 3 that can move inside the base frame 1 are fixedly connected to the lower side of the lower frame 2. Multiple electric telescopic rods 4 are fixedly connected to the upper side of the movable wheels 3. The piston rods of the multiple electric telescopic rods 4 are all fixedly connected to the tabletop 5. The horizontal position of the rear axle 17 of the tractor to be repaired can be adjusted by sliding the lower frame 2. The height of the rear axle 17 of the tractor to be repaired can be adjusted by activating the electric telescopic rods 4, thus making it relatively easy to adjust the position of the rear axle 17 of the tractor to be repaired.

[0028] like Figure 1 , Figure 3 As shown, L-shaped brackets 20 are fixedly connected to both sides of the lower frame 2. Screws 18 are threadedly connected to the outer side of the L-shaped brackets 20. Multiple threaded holes 19 are opened on the base frame 1. The screws 18 are threadedly connected to one of the threaded holes 19. When in use, when the moving wheel 3 drives the device to a suitable position, the moving wheel 3 can be locked by rotating the screws 18 and engaging with the threaded holes 19.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
