[0002] A winch, also known as a hoist, is a lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. A winch can lift vertically, pull horizontally or tilt heavy objects. It can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used due to its simple operation, large rope winding capacity and convenient relocation. It is mainly used for lifting or flat towing materials in construction, water conservancy projects, forestry, mining, docks, etc.

[0003] Large-tonnage winches are mainly used for hoisting and unloading heavy objects. After long-term use, the motor connecting shaft of the winch is prone to wear and other damages. The damaged motor connecting shaft needs to be repaired, but due to the large size and weight of the overall winch, the overall equipment transportation and maintenance costs are high, and the repair cycle of the motor connecting shaft is prolonged, so further improvements are needed.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] Embodiment 1:

[0037] The present application embodiment discloses a large winch motor connecting shaft repair mechanism, referring to Figure 1 , including a winch body 1, a processing frame 2 disposed on the winch body 1, a processing tool table 3 slidably connected to the processing frame 2, and an adjustment component 4 for adjusting the sliding position of the processing tool table 3. The winch body 1 is provided with a mounting plate 11 located below the motor connecting shaft, and the axial direction of the motor connecting shaft is parallel to the plate surface of the mounting plate 11. In this embodiment, the mounting plate 11 is fixedly connected to the winch body 1, and the winch body 1 is fixedly connected with a bracket 12 for supporting the mounting plate 11. The processing frame 2 is detachably connected to the mounting plate 11, and specifically, the processing frame 2 is locked to the mounting plate 11 by bolts.

[0038] Reference Figure 2 , both sides of the upper end surface of the processing frame 2 are fixedly connected with fixed plates 21, and the two fixed plates 21 are distributed along the axial direction of the motor connecting shaft. Two guide rods 22 are fixedly connected between the two fixed plates 21, and the axial direction of the guide rod 22 is parallel to the axial direction of the motor connecting shaft, and the processing tool table 3 is slidably sleeved on the guide rod 22. The adjustment component 4 includes an adjustment screw 41 and a handwheel 42 rotatably connected to the fixed plate 21, and the axial direction of the adjustment screw 41 is parallel to the axial direction of the guide rod 22. The adjustment screw 41 is located between the two guide rods 22, and the adjustment screw 41 is threadedly penetrated in the processing tool table 3. The outer diameter of the handwheel 42 is larger than the outer diameter of the adjustment screw 41, and the handwheel 42 is coaxially fixedly connected to the end of the adjustment screw 41 away from the winch body 1. In other embodiments, a motor can also be used to directly drive the adjustment screw 41 to rotate.

[0039] Reference Figure 1 A machining tool 31 for turning the motor connecting shaft of the winch body 1 is provided on the machining tool stand 3. Specifically, the machining tool 31 is fixedly connected to the machining tool stand 3 by bolts.

[0040] The implementation principle of a large winch motor connecting shaft repair mechanism in the embodiment of the present application is as follows: the processing frame 2 is directly arranged on the winch body 1. When the motor connecting shaft on the winch body 1 is damaged and needs to be repaired, the motor on the winch body 1 is started to drive the motor connecting shaft to rotate. At the same time, the staff drives the adjusting screw 41 to rotate by turning the hand wheel 42, thereby adjusting the sliding position of the processing tool table 3, so that the processing tool 31 abuts against the outer wall of the motor connecting shaft to perform turning repair operations on the motor connecting shaft. The motor connecting shaft is directly processed and repaired on the winch site without the need to transfer and transport the winch, which greatly saves transportation costs and improves processing and repair efficiency.

[0041] Embodiment 2:

[0042] The difference from Example 1 is that, referring to Figure 3 The mounting plate 11 is vertically slidably connected to the outer wall of the winch body 1, and the winch body 1 is provided with a lifting drive member for driving the mounting plate 11 to rise and fall. Specifically, the lifting drive member is a lifting cylinder 13 located below the mounting plate 11, the cylinder body of the lifting cylinder 13 is fixedly connected to the base of the winch body 1, and the piston rod of the lifting cylinder 13 is fixedly connected to the lower end surface of the mounting plate 11. The lifting and sliding movement of the mounting plate 11 is realized by the extension and retraction of the piston rod of the lifting cylinder 13, thereby adjusting the height position of the machining tool 31.

[0043] Embodiment 3:

[0044] The difference from Example 1 is that, referring to Figure 4 One end of the processing frame 2 is fixedly connected with a hinge shaft 23, and the hinge shaft 23 is rotatably connected to the side wall of the winch body 1, so that the processing frame 2 is hinged to the winch body 1, and the winch body 1 is provided with a swing driving member for driving the free end of the processing frame 2 to rotate. Specifically, the swing driving member is a swing cylinder 14, the cylinder body of the swing cylinder 14 is hinged to the lower side wall of the winch body 1, and the piston rod of the swing cylinder 14 is hinged to the free end of the processing frame 2.

[0045] Under normal circumstances, the piston rod of the swing cylinder 14 is in a retracted state, so that the processing frame 2 is in a vertical state, reducing the space occupied by the processing frame 2. When the motor connecting shaft needs to be repaired, the piston rod of the swing cylinder 14 is extended to drive the free end of the processing frame 2 to rotate upward so that the processing frame 2 is in a horizontal state. Finally, the sliding position of the processing tool table 3 is adjusted by the adjustment component 4, so that the processing tool 31 abuts against the outer wall of the motor connecting shaft to perform turning repair operations on the motor connecting shaft.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
