Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses a hoist for hoisting sprocket.

The first embodiment is as follows:

referring to fig. 1 and 2, the chain wheel 2 is included, and the chain wheel 2 is provided with a hanger 1, and the hanger 1 is mutually hooked with a hook lock on a hoisting device.

Referring to fig. 1 and 2, hanger 1 includes two jibs 3 and connects connecting rod 4 of two jibs 3, and two jibs 3 and connecting rod 4 integrated into one piece, and two jibs 3 all are vertical setting, the shaping of all buckling of one end that two jibs 3 deviate from connecting rod 4 has hook rod 31, the length direction of hook rod 31 perpendicular to jib 3's length direction, and hook rod 31 is close to a side of connecting rod 4 and the downside butt of the support floor 22 of sprocket 2, the shaping has rings 41 on the intermediate position of connecting rod 4, and rings 41 collude with hoisting equipment's hook lock and link to each other. The worker passes the hook rod 31 through the fan-shaped hole 21 of the chain wheel 2, so that the hook rod 31 is abutted to the support rib plate 22 of the chain wheel 2, and then the lifting ring 41 on the connecting rod 4 is hooked with the hook lock of the lifting device, so that the lifting operation is carried out.

Referring to fig. 1 and 2, the two hook levers 31 are bent in a direction to approach each other, and an abutment plane 32 is formed on one side surface of the two hook levers 31 that approaches the connecting link 4. The hook lever 31 is fitted into the sector hole 21 of the sprocket 2, and the abutment plane 32 of the hook lever 31 abuts against the support rib 22 of the sprocket 2, thereby allowing the hanger 1 to stably hoist the sprocket 2.

The implementation principle of the lifting appliance for lifting the chain wheel 2 in the embodiment of the application is as follows: in actual work, a worker hooks the hook rod 31 at the lower end of the boom 3 with the support rib plate 22 on the sprocket 2, so that the abutment plane 32 on the hook rod 31 abuts against the support rib plate 22; then, the worker hooks the hanging ring 41 on the connecting rod 4 and the hook lock of the hoisting device to perform the hoisting operation of the sprocket 2.

Example two:

the difference from the first embodiment is that: referring to fig. 1, a telescopic assembly 5 for adjusting the distance between two booms 3 is provided on a hanger 1.

Referring to fig. 4 and 5, the telescopic assembly 5 includes a guide tube 51 and a slide rod 52, the suspension ring 41 is fixed at a middle position of the guide tube 51, the slide rod 52 is fixed at one end of the suspension rod 3 away from the hook rod 31, a length direction of the slide rod 52 is perpendicular to a length direction of the suspension rod 3, the slide rods 52 correspond to the two suspension rods 3 one by one, and both the slide rods 52 are slidably connected in the guide tube 51. The worker can adapt the hanger 1 to sprockets 2 of different sizes by pulling the slide bar 52 so that the distance between the two booms 3 is changed. A spring 6 is fixedly connected between the two sliding rods 52, and the spring 6 is positioned in the middle of the guide pipe 51. After the guide rod is loosened by the worker, the spring 6 can reset the guide rod, so that the worker can conveniently use the hanging bracket 1.

Referring to fig. 4 and 5, the end of the hook rod 31 away from the boom 3 is formed with a retaining rod 7, the end of the retaining rod 7 away from the boom 3 faces the guide tube 51, and the length direction of the retaining rod 7 is parallel to the length direction of the boom 3. The anti-dropping rod 7 can stably hook the hanger 1 and the chain wheel 2. A cushion 8 is adhered and fixed on one side surface of the hook rod 31 close to the chain wheel 2. The cushion 8 reduces the risk of damage to the support ribs 22 of the sprocket wheel 2 caused by the hook bar 31.

The implementation principle of the lifting appliance for lifting the chain wheel in the embodiment of the application is as follows: in actual work, a worker pulls the two suspenders 3, so that the distance between the two suspenders 3 is adjusted; then, the hook rod 31 and the anti-drop rod 7 are passed through the fan-shaped hole 21 of the chain wheel 2, so that the hook rod 31 and the anti-drop rod 7 are mutually hooked with the support rib plate 22 of the chain wheel 2; finally, the worker hooks the hanging ring 41 on the connecting rod 4 and the hook lock of the hoisting device, so as to hoist the chain wheel 2.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
