A reinforcing block 19 is arranged at the contact position between the beam frame 4 and the lifting column 3, and the reinforcing block 19 is welded to the lifting column 3 and the beam frame 4;

[0028] An installation groove 5, which is arranged in the middle part of the beam frame 4. A moving seat 6 is arranged inside the installation groove 5. There are two moving seats 6, and the moving seat 6 is movably connected to the beam frame 4. A winch assembly 7 is arranged above both moving seats 6, and the winch assembly 7 is fixedly connected to the moving seat 6. Hooks 8 are arranged below both moving seats 6, and the hooks 8 are integrally connected to the winch assembly 7.

[0029] During use: Move the device to the hoisting area, move the two moving seats 6 according to the hoisting requirements, lower the two hooks 8 to connect with the equipment to be hoisted. At the same time, start the two winch assemblies 7 and control the running speed. Hoisting is achieved through the winch assemblies 7 and the hooks 8. Using two hoisting mechanisms can balance the force, reduce the stress condition of the hoisting rope, perform hoisting more smoothly, and can also prevent the danger of the hoisting rope breaking in single-hoisting-rope hoisting.

[0030] Please refer to Figure 1 , Figure 3 and Figure 4 , sliding grooves 18 are arranged on the inner wall of the installation groove 5. There are two sliding grooves 18. Connecting blocks 16 are arranged inside both sliding grooves 18, and the connecting blocks 16 are slidably connected to the beam frame 4. The connecting blocks 16 are arranged on both sides of the moving seat 6, and the connecting blocks 16 are fixedly connected to the moving seat 6. By sliding the connecting blocks 16 along the sliding grooves 18, the moving seat 6 can be driven to translate, realizing the position movement adjustment of the hoisting mechanism, and can perform hoisting operations on objects of different sizes.

[0031] Please refer to Figure 1 and Figure 4, on both sides of the beam frame 4, a first motor 9 and a second motor 10 are respectively arranged, and both the first motor 9 and the second motor 10 are connected to the beam frame 4 by screws. Inside both of the two chutes 18, a ball screw 17 is arranged, and one end of the ball screw 17 is respectively connected to the output ends of the first motor 9 and the second motor 10. The ball screw 17 is arranged through the connecting block 16, and the ball screw 17 is in threaded connection with the connecting block 16. By driving the ball screw 17 to rotate through the first motor 9 and the second motor 10, and driving the connecting block 16 to move as the ball screw 17 rotates, the translation of the two moving seats 6 can be separated and realized.

[0032] Please refer to Figure 2 , inside the telescopic cavity 15, a hydraulic cylinder 14 is arranged, and both ends of the hydraulic cylinder 14 are respectively fixedly connected to the support seat 1 and the lifting column 3. By driving the lifting column 3 to lift and lower through the hydraulic cylinder 14, the height of the hoisting device is changed.

[0033] Please refer to Figure 2 , on the inner wall of the telescopic cavity 15, balls 13 are arranged, and the balls 13 are in rolling connection with the support seat 1. The balls 13 are arranged on both sides of the lifting column 3, and the balls 13 are in contact with the lifting column 3.

There are four traveling wheel mechanisms 2, and the traveling wheel mechanisms 2 are connected to the support seat 1 by screws. Through the traveling wheel mechanisms 2, the hoisting device can walk, and the hoisting device can be moved and used.

[0036] Working principle: The hoisting device is moved by means of the walking wheel mechanism 2 and moved to the hoisting area. According to the hoisting requirements, the hydraulic cylinder 14 is driven to drive the lifting column 3 to rise and fall, changing the height of the hoisting device. After the height of the hoisting device is adjusted, the telescopic end of the electric push rod 11 is inserted into the limit hole 12 to limit the lifting column 3; the first motor 9 and the second motor 10 are started to drive the ball screw 17 to rotate. As the ball screw 17 rotates, the connecting block 16 is driven to move, and then the two moving seats 6 are driven to translate, moving the lifting mechanism to a suitable position. The two lifting hooks 8 are lowered and connected to the equipment to be hoisted. The winch assembly 7 is started to pull the lifting hook 8, and the running speed of the winch assembly 7 is controlled. Hoisting is achieved through the winch assembly 7 and the lifting hook 8.
