[0024] Further, the upper surface of the vertical section of L-shaped adjusting block 103 is fixedly connected with a lubricating support frame 105, and the upper surface of the lubricating support frame 105 is symmetrically slidably provided with two extrusion support plates 106. The two extrusion support plates 106 are fixedly installed with a lubricating capsule therebetween. The lubricating capsule is made of elastic material. Lubricant is stored in the lubricating capsule. The lubricating capsule and the hollow end of the L-shaped adjusting block 103 are connected by a hose.

[0025] Further, a hoisting support assembly 2 is arranged below the lifting control assembly 1. The hoisting support assembly 2 comprises two auxiliary wheels 201 and a lifting cable 202. The two ends of the lifting cable 202 are fixedly connected to the circumferential side surfaces of the two lifting control rollers 102, respectively. The lifting cable 202 sequentially passes through the adjusting through -hole 104, the hoisting through -hole, and the auxiliary wheel 201. By controlling the length of the lifting cable 202 between the auxiliary wheel 201 and the exposed hoisting through -hole, the position height of the hoisting support assembly 2 can be adjusted.

[0026] The operation process of the embodiment is as follows: during the hoisting operation, the lifting control rollers 102 are synchronously rotated. The lifting cable 202 wound around the circumferential side surfaces of the lifting control rollers 102 is gradually released. The lifting cable 202 passes through the adjusting through -hole 104 and the hoisting through -hole and is then transmitted out. In this process, the extrusion support plates 106 are synchronously horizontally moved and approach each other, thereby pressurizing the lubricating capsule. The lubricant in the lubricating capsule flows to the hollow end of the L-shaped adjusting block 103 through the extrusion and the hose. When the lifting cable 202 passes through the adjusting through -hole 104, the lubricant flows out through the lubricating ports, thereby lubricating the passing lifting cable 202. The length of the lifting cable 202 between the auxiliary wheel 201 and the exposed hoisting through -hole is gradually increased, thereby causing the hoisting support assembly 2 to gradually descend, until the position of the object to be hoisted and the hoisting support assembly 2 is limited. The two lifting control rollers 102 are controlled to be reversely rotated, thereby winding the lifting cable 202. The length of the lifting cable 202 between the auxiliary wheel 201 and the exposed hoisting through -hole is gradually decreased. The hoisting support assembly 2 drives the object to be hoisted to synchronously move upward, thereby completing the hoisting operation of the object. Embodiment two
