Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to a special hoisting tool for a waste hopper. Background Art

[0002] The headless rolling process is a technological breakthrough in the production of traditional hot-rolled strip steel. It refers to a technology in which the slab after rough rolling is welded on the intermediate roller and continuously passes through the finishing mill. Compared with the traditional production method, the strip steel is rolled under constant tension conditions because the strip steel threading and tail swinging links in the finishing mill are reduced. Therefore, the geometric accuracy of the head and tail of the strip steel and the proportion of poor plate shape are greatly reduced, the mechanical properties are more uniform, the yield rate is improved, the labor productivity of the unit is improved, and ultra-thin strip steel can be produced in large quantities and stably.

[0003] The pickling and leveling line based on headless rolling hot-rolled raw materials is a continuously running unit. During the production process, it is necessary to cut off the welds and the parts of the head and tail that do not meet the needs of customers. The cut waste slides into the waste hopper through the guide plate. Usually, the waste hopper is arranged in the area near the shearing transmission side of the unit. Since the waste hopper cannot be directly switched and transported by rail, it needs to be replaced by a crane. The weight of the waste hopper is large, and usually two 20-ton steel wire ropes are hung on the waste hopper lifting lugs for lifting. Before lifting, it is necessary to manually enter the waste hopper pit to assist in hanging the steel wire rope, and cooperate with the crane hook to rise, so that the steel wire rope can be securely hung on the waste hopper lifting lug.

[0004] However, the pit space is narrow, and there is a risk of the waste bucket shaking and the hoisting personnel being squeezed. In addition, the waste falls freely when it falls into the waste bucket, and the waste is relatively messy in the waste bucket. The center of gravity of the waste bucket filled with waste is not on the center of gravity of the waste bucket; at the same time, the wire rope and the hook position are connected by sliding, and the horizontal height of the four wire rope hooks cannot be guaranteed to be consistent. This causes the waste bucket to shake during the crane's reverse transportation, and there is also a risk of the wire rope hanging on the crane hook position sliding, resulting in the risk of the waste bucket tipping over and falling during the lifting process. Utility Model Content

[0005] In view of the dangers of the waste hopper during loading and the risk of sliding during transportation in the prior art, the utility model provides a special hoist for the waste hopper to solve the above problems.

[0006] A special sling for a waste hopper comprises a crossbeam; longitudinal beams are arranged at both ends of the crossbeam, the longitudinal beams are arranged horizontally and perpendicular to the crossbeam; longitudinal beam lifting ears are arranged at both ends of the two longitudinal beams; the longitudinal beam lifting ears are connected to the cantilever through a pin shaft; a hook is arranged at one end of the cantilever opposite to the longitudinal beam lifting ear; a hanging arm is arranged at the midpoint of the crossbeam, and a sling lifting ear is arranged at one end of the hanging arm opposite to the crossbeam.

[0007] Furthermore, the cantilever and the hook are integrally formed.

[0008] Furthermore, reinforcing ribs are provided at the connection between the cross beam and the longitudinal beam, which can increase the overall strength of the sling and stabilize the center of gravity of the sling.

[0009] Furthermore, the special sling for the waste hopper is made of Q355B material.

[0010] Furthermore, the cross beam is welded to the longitudinal beam; and the cross beam is welded to the suspension arm.

[0011] Furthermore, the length of the cross beam is 1600 mm; the length of the longitudinal beam is 1700 mm; and the total length of the cantilever and the hook is 1320 mm.

[0012] The working principle of the utility model is as follows: first hang the sling on the crane hook through the sling ear, and the four cantilevers of the sling are freely hanging down. By moving the position of the crane, the four cantilevers fall to both sides of the waste bucket, and the hook under the cantilever faces the ear of the waste bucket. The center point of the hook is 100-150mm below the cantilever ear, and the horizontal distance is 50-100mm; by moving the position of the crane, the special sling is moved 120-150mm along the length direction of the waste bucket close to the ear of the waste bucket, and the cantilever leans against the ear of the waste bucket and forms a certain angle of 5°-10°; continue to operate the crane to make the sling rise slowly, and the cantilever hook of the sling is hung firmly with the ear of the waste bucket by gravity; then continue to operate the crane to move the waste bucket to a position where the waste truck can be pulled and transported, and then use the same method to move the empty waste bucket to the storage position of the waste bucket in the pit. The special sling is disconnected from the waste bucket by the opposite operation.

[0013] The beneficial effects of the utility model are:

[0014] The utility model provides a special hoist for waste hopper, which is a special hoist for hanging by a crane hook. The waste hopper can be hoisted out by moving the crane position. It is convenient and safe. The four cantilever lengths are stable and there is no possibility of movement during the hoisting process. The operator no longer needs to enter the pit to assist in the hooking, which effectively improves the working efficiency and greatly reduces the safety risk. BRIEF DESCRIPTION OF THE DRAWINGS
