[0026] Adjusting assembly 2, the adjusting assembly 2 includes a movable sleeve 201. The top of the movable sleeve 201 is fixedly connected to the bottom of the cage body 1. An extension plate 202 is movably connected inside the movable sleeve 201. One side of the extension plate 202 away from the cage body 1 is fixedly connected to an extension arm 203. A threaded rod 204 is connected inside the extension plate 202 by thread. One section of the threaded rod 204 without thread is movably connected by a bearing to a first limit seat 205. One end of the threaded rod 204 close to the first limit seat 205 is fixedly connected to a first bevel gear 206. The first bevel gear 206 is connected by meshing transmission to a second bevel gear 207. One side of the second bevel gear 207 is fixedly connected to an adjusting shaft 209. The side surface of the adjusting shaft 209 is movably connected by a bearing to a second limit seat 208. The bottoms of the second limit seat 208 and the first limit seat 205 are both fixedly connected to the bottom inner wall of the movable sleeve 201;

[0027] Compensation assembly 3, the compensation assembly 3 includes a first clamping plate 301. One side of the first clamping plate 301 is fixedly connected to a connecting rod 302. A pulley 305 is movably sleeved on the side surface of the connecting rod 302 by a bearing. The side surface of the connecting rod 302 is movably sleeved with a second clamping plate 303. An avoidance groove 304 is provided on one side of the second clamping plate 303 away from the pulley 305. A threaded section of the connecting rod 302 is threadedly connected with a nut that restricts the movement of the connecting rod 302;

[0028] Fixing assembly 4, the fixing assembly 4 includes a bolt 401. The end of the bolt 401 is fixedly connected to a pin shaft 402. The bolt 401 is threadedly connected to the extension arm 203. The two pin shafts 402 are respectively rotatably connected to the notches in the middle of the first clamping plate 301 and the second clamping plate 303. An inclined threaded hole 405 is provided at the end of the extension arm 203. An internal hexagonal screw 403 is threadedly connected in the inclined threaded hole 405. The end of the internal hexagonal screw 403 abuts against a bottom plate 404. One side of the bottom plate 404 is fixedly connected to the side of the first clamping plate 301 away from the connecting rod 302.

[0029] In this embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, the two pulleys 305 are movably connected to the side surface of the slide rail 5. The two ends of the slide rail 5 are fixedly connected to a fixing frame 6 together.

[0030] In this embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, there are two adjusting assemblies 2, and the two adjusting assemblies 2 are symmetrically distributed. There are two extension arms 203 on one side of the extension plate 202.

[0031] In this embodiment, as Figure 3 、 Figure 4 and Figure 5As shown, the side surface of the pulley 305 fits with the side surface of the slide rail 5. In each fixing component 4, the first clamping plate 301 and the connecting rod 302 are inclined. During assembly, first, the hoist is used to lift the cage main body 1 by a certain height to facilitate manual assembly and fixation. Then, the adjusting shaft 209 is rotated by an inner hexagon wrench to move the extension plate 202 outwards on both sides. After that, the extension arm 203 is assembled with screws. After the assembly of the extension arm 203 is completed, the second clamping plate 303 is assembled through the connecting rod 302 and the nut on the first clamping plate 301. Then, the compensation component 3 is assembled through the bolt 401 and the pin shaft 402. After the installation of the compensation component 3 is completed, at this time, the compensation component 3 rotates around the center of the pin shaft 402. Then, it is abutted against the bottom plate 404 through the inner hexagon screw 403, so as to rotate the compensation component 3 until the two pulleys 305 are attached to the slide rail 5. Repeat the above operations to complete the installation of multiple compensation components 3. Through the compensation component 3 and the fixing component 4, the compensation component 3 can be inclined. By changing the inclination angle, the pulley 305 can be effectively attached to the slide rail 5, avoiding gaps between structures and causing the cage main body 1 to shake. At the same time, by changing the angle of the compensation component 3, the contact gap between the cage main body 1 and the fixing frame 6 is eliminated, and the gap is compensated, thereby reducing the assembly accuracy. At the same time, the inclination angle of the compensation component 3 and the position of the extension plate 202 can be adjusted after the assembly is completed, achieving the effect of adjusting after assembly, improving the flexibility of assembly, reducing the requirement for assembly accuracy, and facilitating manual assembly. Through the adjusting component 2 and the fixing component 4, when installing the cage main body 1, there is no need for tight assembly requirements and the production requirements of structural parts. By the adjusting component 2, the extension plate 202 supporting the cage main body 1 extends outwards on both sides, thereby reducing the size requirements for the fixing frame 6, enabling the cage main body 1 to be assembled in the fixing frame 6 with a certain interval size, and thus improving the compatibility.

[0032] In this embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, the top hook of the cage main body 1 is used to hang the traction end of the hoist, and metal nets 7 for protection are fixedly connected to both sides of the cage main body 1.

[0033] In this embodiment, as Figure 3 、 Figure 4 and Figure 5 shown, the end of the adjusting shaft 209 passes through and is movably connected to the movable sleeve 201, and one end of the adjusting shaft 209 passing through the movable sleeve 201 rotates the adjusting shaft 209 through a hexagonal plate.

[0034] The usage method and advantages of the present invention: For this adjustable cage mechanism of the construction hoist, during use, the working process is as follows:

[0035] As Figure 1 、Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , during assembly, first use a winch to lift the main body 1 of the cage to a certain height to facilitate manual assembly and fixation. Then, use an Allen wrench to rotate the adjustment shaft 209 to move the extension plate 202 outwards on both sides. After that, assemble the extension arm 203 with screws. After the extension arm 203 is assembled, assemble the second clamping plate 303 through the connecting rod 302 and nut on the first clamping plate 301. Then, assemble the compensation assembly 3 with bolts 401 and pin shafts 402. After the compensation assembly 3 is installed, at this time, the compensation assembly 3 rotates around the center of the pin shaft 402. Then, use an Allen screw 403 to abut against the bottom plate 404, so as to rotate the compensation assembly 3 until the two pulleys 305 are attached to the slide rail 5. Repeat the above operations to complete the installation of multiple compensation assemblies 3.
