[0028] The present utility model provides a hoisting device based on a pulley block as shown in Figure 1 the figure, which includes a fixing frame 1 and further includes:

[0029] Two installation mechanisms 2 are provided, which are respectively arranged at both ends of the inner top of the fixing frame 1 and are used for installing and fixing the pulley block;

[0030] A suspension mechanism 3 is arranged at the bottom of the two installation mechanisms 2 and is used for suspending and hoisting the equipment.

[0031] In order to conveniently install and disassemble the suspension mechanism 3, as shown in Figure 1-2 and Figure 4 the figure, the installation mechanism 2 includes adjusting screws 202. The two adjusting screws 202 are respectively arranged on the inner walls at both ends of the inner top of the fixing frame 1. Installation seats 203 are threadedly sleeved on the outer sides of the two adjusting screws 202. Fastening screws 205 are arranged on the inner walls of both sides of the bottom of the installation seats 203. Clamping plates 206 are threadedly sleeved on the outer sides of the two fastening screws 205. Rotating the adjusting screw 202 can adjust the position of the installation seat 203, and further can adjust the installation position of the suspension mechanism 3. Rotating the fastening screw 205 can adjust the position of the clamping plate 206, so that the installation seat 203 can conveniently install and disassemble the rotating buckle 301.

[0032] In order to conveniently hoist and repair the equipment in the wind farm, as shown inFigure 1-2 and Figure 5 As shown in Figure 5 , the suspension mechanism 3 includes two rotating buckles 301 and a movable pulley 303. The two rotating buckles 301 are respectively sleeved on the outer sides of the two clamping plates 206 at both ends. A fixed pulley 302 is fixedly installed at the bottom of one of the rotating buckles 301. A nylon rope 305 bypasses the bottom of the driven pulley 303 and passes through the top of the fixed pulley 302. A hanging ring 304 is fixedly installed at the outer bottom of the movable pulley 303. The fixed pulley 302 and the nylon rope 305 can be fixed through the rotating buckle 301, and the equipment to be repaired can be lifted through the hanging ring 304. Furthermore, through the arrangement of the fixed pulley 302 and the movable pulley 303, the staff can conveniently lift and repair the equipment.

[0033] To make the mounting seat 203 stable during movement, as Figure 1-3 shown in Figure 1-3 , the mounting mechanism 2 includes mounting grooves 201. There are two mounting grooves 201, which are respectively opened on the inner walls at both ends of the top of the inner side of the fixing frame 1. The inner walls of the two mounting grooves 201 are respectively rotatably connected to two adjusting screws 202, and the inner walls of the two mounting grooves 201 are respectively movably connected to the outer walls of the tops of the two mounting seats 203. Moving grooves 204 are opened on the inner walls of both sides at the bottom of the two mounting seats 203. The mounting grooves 201 can limit the movement of the mounting seats 203, so that the mounting seats 203 remain stable during movement, and further, the mounting position of the suspension mechanism 3 can be adjusted stably.

[0034] To make the clamping plate 206 stably install and fix the rotating buckle 301, as Figure 2 and Figure 4-5 shown in Figure 2 and Figure 4-5 , the inner wall of the moving groove 204 is rotatably connected to the adjacent fastening screw 205, and the inner wall of the moving groove 204 is movably connected to the outer wall of the top of the adjacent clamping plate 206. The left vertical cross-section of the clamping plate 206 is set as an L-shaped structure. The common width dimension of the horizontal parts of the two clamping plates 206 is the same as the width dimension of the rotating buckle 301. The moving groove 204 can limit the movement of the clamping plate 206, so that the clamping plate 206 remains stable during movement, and further, the two clamping plates 206 at the same end can stably install and fix the adjacent rotating buckle 301.

[0035] To make the suspension mechanism 3 stably lift and repair the equipment, as Figure 2 and Figure 5 shown in Figure 2 and Figure 5 , the diameter dimension of the fixed pulley 302 is the same as the diameter dimension of the movable pulley 303. The movable pulley 303 is arranged at the gap between the two rotating buckles 301. Through the combination of the fixed pulley 302 and the movable pulley 303, the suspension mechanism 3 can conveniently lift and repair the equipment of the wind farm.

[0036] When repairing the equipment of a wind farm, two swivels 301 are respectively fixed to the bottoms of two mounting seats 203. Then, by rotating the two fastening screws 205 at the same end, the distance between the two clamping plates 206 at the same end can be adjusted, so that the two clamping plates 206 at the same end can clamp and fix the adjacent swivels 301. At the same time, the movable groove 204 can limit the movement of the clamping plate 206, so that the clamping plate 206 remains stable during the movement. Then, by rotating the two adjusting screws 202, the two mounting seats 203 move along the inner walls of the adjacent mounting grooves 201 on their outer sides, and then the positions of the two swivels 301 can be adjusted. Then, one end of the nylon rope 305 is fixedly connected to one of the swivels 301, and at the same time, the fixed pulley 302 is installed at the bottom of the other swivel 301. Then, the nylon rope 305 can bypass the bottom of the movable pulley 303 and then wind out from the top of the fixed pulley 302 and be stretched by the staff. Then, the equipment to be lifted and repaired can be connected through the hanging ring 304 at the bottom of the movable pulley 303. Then, by the staff pulling the nylon rope 305, through the action of the fixed pulley 302 and the movable pulley 303, the equipment can be conveniently lifted, which is convenient for the staff to repair the equipment. This embodiment specifically solves the problems in the prior art that it is impossible to conveniently adjust the installation position of the pulley block according to requirements, and at the same time, it is impossible to conveniently install and disassemble the pulley block, which will affect the maintenance efficiency of the wind farm equipment.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
