[0022] The utility model provides Figure 1-4 The hoisting mechanism for installing mining machinery and equipment shown in the figure includes a trapezoidal support column A1 and a trapezoidal support column B2 symmetrically arranged on the left side of the trapezoidal support column A1. A hoisting gantry 8 is arranged between the top of the trapezoidal support column A1 and the top of the trapezoidal support column B2. A horizontal displacement machine base 13 is arranged on the outside of the hoisting gantry 8. A cable drum box 10 is arranged at the bottom of the horizontal displacement machine base 13. An inlet and outlet 6 is arranged at the bottom of the cable drum box 10. A cable retracting shaft is fixed laterally inside the center of the cable drum box 10.

Cable 5, the bottom end of the lifting cable 5 passes through the inlet and outlet 6, the bottom end of the lifting cable 5 is fixed with a hook 4, the bottom ends of the trapezoidal support column A1 and the trapezoidal support column B2 are welded with a placement base 3, and the bottom end of the placement base 3 can be directly installed with a moving wheel, the trapezoidal support column A1 and the trapezoidal support column B2 are provided with a vertical reinforcement column 16 at the center, and the upper and lower ends of the vertical reinforcement column 16 are fixedly connected to the inner walls of the upper and lower ends of the trapezoidal support column A1 and the trapezoidal support column B2 by welding, the trapezoidal support column A1 and the trapezoidal support column B2 and The vertical reinforcement pillars 16 inside it provide stable support for the entire lifting mechanism, and the placement of the base 3 and the moving wheels allows the lifting mechanism to be easily moved to different working positions. Metal fixing covers 7 are provided on the left and right ends of the lifting gantry 8. The two metal fixing covers 7 are respectively placed on the top of the trapezoidal support column A1 and the trapezoidal support column B2, and the trapezoidal support column A1 and the trapezoidal support column B2 are fixedly connected to the metal fixing covers 7 by multiple screws.

The driving wheel is located inside the I-shaped groove at the front end of the lifting gantry 8. The horizontal displacement motor 11 can drive the horizontal displacement machine base 13 to move left and right on the lifting gantry 8 through the driving wheel. The lifting gantry 8 provides a moving track for the horizontal displacement machine base 13. The horizontal displacement machine base 13 moves left and right on the lifting gantry 8 through the horizontal displacement motor 11 and the driving wheel, thereby realizing the horizontal displacement of the lifting equipment.
[0023] like Figure 1 and Figure 2As shown, a brake 9 is provided at the left end of the cable drum box 10, a reducer 14 is provided at the right end of the cable drum box 10, and a cable motor 15 is provided at the right end of the reducer 14.

When the mining machinery and equipment reaches above the designated position, slowly loosen the lifting cable 5 and place the equipment steadily in the predetermined position, thereby completing the lifting operation of the large-scale mining machinery and equipment.
[0024] like Figure 1 、 Figure 3 and Figure 4As shown, the cable drum box 10 and the horizontal displacement machine base 13 are externally connected with an overload reinforcement device 12, and the overload reinforcement device 12 includes a U-shaped metal sleeve A17, a U-shaped metal sleeve B18, a metal support top plate 19 and a reinforcement support block 20. The U-shaped metal sleeve A17 and the U-shaped metal sleeve B18 are respectively sleeved on the left and right sides of the center of the cable drum box 10 and the horizontal displacement machine base 13, and the U-shaped opening directions of the U-shaped metal sleeve A17 and the U-shaped metal sleeve B18 are both facing upward. The top ends of the U-shaped metal sleeve A17 and the U-shaped metal sleeve B18 are connected to the metal support top plate 19 by welding. The metal support top plate 19 is located on the upper side of the horizontal displacement machine base 13. Reinforcement support blocks 20 are provided on the bottom of the left and right ends of the metal support top plate 19. The U-shaped metal sleeve A17 and the U-shaped metal sleeve B18 are respectively sleeved on the left and right sides of the center of the cable drum box 10 and the horizontal displacement machine base 13. It is connected to the metal support top plate 19 by welding to form a stable frame structure. This structure can effectively enhance the connection strength between the cable drum box 10 and the horizontal displacement machine base 13, and improve the structural stability of the entire lifting mechanism. The length of the metal support top plate 19 is greater than the length of the horizontal displacement machine base 13. The two reinforcement support blocks 20 are respectively located on the left and right sides of the top of the horizontal displacement machine base 13, so that the load can be evenly distributed to avoid local excessive force causing structural deformation or damage. The bottom ends of the U-shaped metal sleeve A17 and the U-shaped metal sleeve B18 are fixedly connected to the bottom end of the cable drum box 10 by multiple screws. The bottom ends of the U-shaped metal sleeve A17 and the U-shaped metal sleeve B18 are fixedly connected to the bottom end of the cable drum box 10 by multiple screws, which is convenient for installation and disassembly. When maintenance or replacement is required, the overload reinforcement device 12 can be quickly removed from the lifting mechanism, thereby improving maintenance efficiency.
[0025] like Figure 1 、 Figure 3 and Figure 4As shown, the overload reinforcement device 12 also includes ball holes 21 and displacement reinforcement balls 22. A plurality of ball holes 21 are equidistantly arranged inside the two reinforcement support blocks 20, and the bottom ends of the plurality of ball holes 21 are all open. Displacement reinforcement balls 22 are arranged inside the plurality of ball holes 21, and the displacement reinforcement balls 22 are made of alloy steel. The cross-sectional shape of the ball holes 21 is three-quarter circular, and a quarter of the bottom end of the displacement reinforcement ball 22 is exposed outside the bottom end of the reinforcement support block 20, and the bottom end of the displacement reinforcement ball 22 is attached to the outer wall of the top end of the lifting gantry 8. The displacement reinforcement ball 22 can rotate universally in the ball holes 21. When the horizontal displacement machine base 13 drives the cable drum box 10 to move left and right on the lifting gantry 8, the displacement reinforcement ball 22 rotates universally in the ball holes 21 to ensure that the overload reinforcement device 12 can move normally and synchronously, avoiding the horizontal displacement machine The seat 13 feels blocked during movement, which ensures the smoothness of the horizontal displacement of the lifting mechanism. This design allows the overload reinforcement device 12 to perfectly cooperate with the horizontal displacement machine seat 13 during the lifting process, even in the face of different movement requirements and complex working conditions, without affecting the efficiency and accuracy of the lifting operation. On the other hand, since the bottom end of the displacement reinforcement ball 22 is supported on the outer wall of the top of the lifting gantry 8, it provides a stable support for the metal support top plate 19, and the metal support top plate 19 is connected to the cable drum box 10 through two U-shaped metal sleeves, so that the metal support top plate 19 can provide overload reinforcement for the cable drum box 10. In the case of overload when lifting heavy objects, this support and reinforcement can effectively share the load and prevent the cable drum box 10 from being damaged due to overload, greatly improving the safety and reliability of the lifting mechanism.
