[0023] As Figures 1 to 4 shown, a base of a crane hoisting mechanism with an auxiliary structure provided by the present utility model includes a base 1, a double-rail trolley 2, and a hoisting mechanism 3. The base 1 is located at the bottom of the double-rail trolley 2. The hoisting mechanism 3 includes a fixing plate 31, and the fixing plate 31 is fixedly installed on the left and right sides of the bottom of the base 1. A servo motor 32 is fixedly installed on one side of the fixing plate 31 close to the right side of the base 1. The output end of the servo motor 32 penetrates through the fixing plate 31 and is fixedly connected to a winch wheel 33. The output end of the servo motor 32 is movably connected to the fixing plate 31. The other end of the winch wheel 33 is movably connected to the fixing plate 31 through a bearing. A steel cable 34 is wound around the surface of the winch wheel 33, and the other end of the steel cable 34 is fixedly connected to a hook 35. Positioning grooves 4 are provided on both the left and right sides of the double-rail trolley 2. A movable plate 5 is movably connected to the inner wall of the positioning groove 4. A connecting mechanism 6 is fixedly connected to the outside of the movable plate 5. A limiting mechanism 7 is provided inside the base 1.

[0024] Referring to Figure 3 , the connecting mechanism 6 includes a first connecting rod 61. The other end of the first connecting rod 61 is fixedly connected to a connecting plate 62. The bottom of the inner side of the connecting plate 62 is fixedly connected to a second connecting rod 63. The other end of the second connecting rod 63 penetrates through the base 1 and extends into the inside of the base 1. The second connecting rod 63 is movably connected to the base 1.

[0025] As a technical optimization solution of the present utility model, by providing the connecting mechanism 6, pulling the connecting plate 62 to move away from the double-rail trolley 2 can drive the first connecting rod 61 to move. The movement of the first connecting rod 61 can drive the movable plate 5 to move and disengage from the positioning groove 4. At the same time, the second connecting rod 63 can play a guiding role in the moving connecting plate 62, thereby improving the stability of the movement of the connecting plate 62 and the first connecting rod 61.

[0026] Referring to Figure 4 , the limiting mechanism 7 includes a movable groove 71. A limiting ring 72 is movably connected to the inner wall of the movable groove 71. The inner wall of the limiting ring 72 is fixedly connected to the surface of the second connecting rod 63. A limiting spring 73 is fixedly connected to the outside of the limiting ring 72. The other end of the limiting spring 73 is fixedly connected to the outer side of the inner wall of the movable groove 71. The inner wall of the limiting spring 73 is movably connected to the surface of the second connecting rod 63.

[0027] As a technical optimization solution of the present utility model, by providing a limiting mechanism 7, the movable groove 71 can perform movable limiting on the limiting ring 72 and the second connecting rod 63, thereby preventing the second connecting rod 63 from detaching from the base 1. The thrust of the limiting spring 73 on the limiting ring 72 can prevent the movable plate 5 from moving inside the positioning groove 4 without human intervention.

[0028] Reference Figure 2 and Figure 3 , a sliding plate 8 is fixedly connected to the bottom of the movable plate 5, and sliding grooves 9 are respectively formed at the bottoms of the inner walls of the positioning groove 4 on the left and right sides of the top of the base 1. The surface of the sliding plate 8 is slidably connected to the inner wall of the sliding groove 9.

[0029] As a technical optimization solution of the present utility model, by providing the sliding plate 8 and the sliding groove 9, the sliding groove 9 can perform upper-lower, front-back limiting on the sliding plate 8, and the upper-lower, front-back limiting of the sliding plate 8 can perform upper-lower, front-back limiting on the movable plate 5, thereby improving the stability of the movement of the movable plate 5.

[0030] Reference Figure 3 , support plates 10 are fixedly connected to the left and right sides of the base 1 respectively, and four guiding holes 11 are formed on the outer sides of the support plates 10. The inner walls of the four guiding holes 11 are movably connected to the surfaces of the first connecting rod 61 and the second connecting rod 63.

[0031] As a technical optimization solution of the present utility model, by providing the support plates 10 and the guiding holes 11, the guiding holes 11 can enable the support plates 10 to support the first connecting rod 61 and the second connecting rod 63, thereby reducing the pressure transmitted from the base 1 to the second connecting rod 63, the connecting plate 62, and the first connecting rod 61.

[0032] Reference Figure 2 , a reinforcing plate 12 is fixedly connected to the top of the movable plate 5, the inner sides of the reinforcing plate 12 are in contact with the left and right sides of the double-track trolley 2, and a groove 13 is formed on the top of the base 1. The bottom of the inner wall of the groove 13 is in contact with the bottom of the double-track trolley 2.

[0033] As a technical optimization solution of the present utility model, by providing the reinforcing plate 12 and the groove 13, the reinforcing plate 12 can improve the stability of the movable plate 5 during movement, and can also improve the stability of the left and right sides of the movable plate 5. The groove 13 can improve the stability between the double-track trolley 2 and the base 1.

[0034] Working principle and usage process of the present utility model: When in use, first hang the hoisting material on the hook 35, and then start the servo motor 32 to drive the winch 33 to rotate through the output end of the servo motor 32. As the winch 33 winds up the steel cable 34, the hoisting material can be driven to move upward. When it is necessary to repair or replace components such as the winch 33 and the steel cable 34, first pull the connecting plate 62, which can drive the first connecting rod 61 and the second connecting rod 63 to move away from the double-rail trolley 2 at the same time. The movement of the first connecting rod 61 can drive the movable plate 5 to move. When the movable plate 5 disengages from the inside of the positioning groove 4, the user can take out the base 1 from the bottom of the double-rail trolley 2, and the disassembly and separation are relatively convenient. After the repair is completed, the user then pulls the connecting plate 62 to drive the movable plate 5 to move away from the groove 13. At the same time, the second connecting rod 63 drives the limiting ring 72 to move. At this time, the limiting ring 72 squeezes the limiting spring 73 to make it contract. Then, by moving the base 1, the inner wall of the groove 13 is attached to the bottom of the double-rail trolley 2. Then release the connecting plate 62. At this time, the rebounding of the limiting spring 73 can sequentially push the limiting ring 72, the second connecting rod 63, the connecting plate 62, the first connecting rod 61 and the movable plate 5 to move. When the movable plate 5 enters the inside of the positioning groove 4, the base 1 can be repositioned at the bottom of the double-rail trolley 2 to complete the installation. At the same time, the support plate 10 and the reinforcement plate 12 can improve the stability of the movement of the first connecting rod 61, the second connecting rod 63 and the movable plate 5.

[0035] In summary: For the base of the hoisting mechanism of a crane with an auxiliary structure, by setting the positioning groove 4 and the movable plate 5, the positioning groove 4 can perform movable limit on the movable plate 5 and the base 1. By moving the movable plate 5 to disengage it from the positioning groove 4, it is convenient for the user to disassemble the base 1, solving the problem that the existing hoisting mechanism usually needs to use bolts to fixedly install the base at the bottom of the double-rail trolley. In actual use, components such as the winch and the steel cable need to be regularly replaced due to large wear. Repeatedly disassembling and installing the bolts is likely to cause the threads to slip, which is likely to cause the base to be insecurely installed and pose a greater risk.
