Description

Technical Field

[0001] The utility model relates to the technical field of lifting lugs, and specifically relates to a lifting lug structure of a scrap steel chute. Background Technique

[0002] In the scrap steel processing and transportation industry, the scrap steel chute is a commonly used device for containing and transferring scrap steel. In order to facilitate the lifting operation of the scrap steel chute, a lifting lug structure is usually provided on the chute. The traditional lifting lug structure generally adopts an integral design, that is, the lifting lug plate is directly welded to the chute, and the through-hole on the lifting lug plate is used to connect the lifting equipment.

[0003] However, in the actual use process, the through-hole part of the lifting lug structure is prone to wear and damage due to the long-term friction and pulling force of the lifting equipment. Especially when the scrap steel chute frequently lifts heavy scrap steel, the wear speed at the through-hole will be faster. Once the through-hole is severely worn, the entire lifting lug structure will be affected and may even not be able to be used normally. At this time, the traditional method is to replace the entire lifting lug plate, which not only requires a lot of time and manpower, but also increases the maintenance cost, because replacing the entire lifting lug plate often means removing and re-welding larger components, which will also have a certain impact on the normal use of the scrap steel chute.

[0004] In addition, although the traditional lifting lug structure will consider a certain connection firmness in design and installation, it often lacks further optimization of the connection strength between the lifting lug plate and the chute, as well as the consideration of convenient replacement when local damage occurs to the lifting lug structure. Therefore, it is of great practical significance to develop a lifting lug structure for a scrap steel chute that can conveniently replace locally worn components, improve the connection firmness, and reduce the maintenance cost. Content of the Utility Model

[0005] The purpose of the utility model is to provide a lifting lug structure of a scrap steel chute to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A lifting lug structure of a scrap steel chute, including a lifting lug plate welded on the surface of the scrap steel chute. A through-hole is opened on the surface of the lifting lug plate. A reserved groove is opened at one end of the through-hole. A splicing plate is inserted into the reserved groove. A wear-resistant sleeve is fixed at the inner ring opening of the splicing plate. A screw rod is inserted into the surface of the splicing plate. One end of the screw rod is fixed on the surface of the reserved groove, and the other end of the screw rod is sleeved and screwed with a nut.

[0007] Preferably, the reserved groove is a "convex" - shaped round hole, the splicing plate is a "T" - shaped circular ring plate, the inner ring diameter of the splicing plate is equal to the diameter of the through - hole, and a rubber pad is fixed on the surface of the reserved groove, and the rubber pad is clamped between the reserved groove and the splicing plate.

[0008] Preferably, the thickness of the assembly plate is less than the depth of the reserved groove, and a rubber sealing plate is fixed to one end of the reserved groove on the outer ring surface. The rubber sealing plate is in the form of a circular ring plate, and the inner ring diameter of the rubber sealing plate is equal to the outer ring diameter of the wear-resistant sleeve.

[0009] Preferably, the surface of the assembly plate has multiple through holes, and the screw and the through hole correspond one-to-one. The screw passes through the through hole, the length of the screw is greater than the thickness of the assembly plate, and the length of the screw is less than the depth of the reserved groove.

[0010] Preferably, the length of the wear-resistant sleeve is equal to the depth of the perforation.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The lifting lug structure of this utility model for scrap steel troughs features a pre-reserved slot at one end of the lifting lug plate, into which an assembly plate with a wear-resistant sleeve is inserted. When the wear-resistant sleeve is severely damaged, simply remove the assembly plate from the pre-reserved slot and replace it with a new wear-resistant sleeve or assembly plate; there is no need to replace the entire lifting lug plate. This design significantly reduces maintenance costs, as replacing a partial component is much more economical than replacing the entire lifting lug plate, while also minimizing maintenance time and disruption to the normal operation of the scrap steel trough.

[0013] A rubber pad is fixed to the surface of the pre-drilled slot. When the assembly plate is inserted into the pre-drilled slot and secured by screws and nuts, the pre-drilled slot compresses the rubber pad, clamping it between the slot and the assembly plate. The elasticity of the rubber pad provides cushioning and prevents loosening, effectively preventing the screws and nuts from loosening due to vibration during hoisting, ensuring the stable fixation of the assembly plate, and thus ensuring the reliability of the entire lifting lug structure.

[0024] The usage method of the lifting lug structure of the scrap steel chute:

[0025] The bottom end of the lifting lug 1 is welded to the top surface of the side plate of the scrap steel trough. At this time, the connecting pieces 11 on both sides of the lifting lug 1 rest against the sides of the side plate of the scrap steel trough. The connecting pieces 11 and the side plate of the scrap steel trough are welded together to strengthen the connection between the lifting lug 1 and the scrap steel trough. During operation, the rubber sealing sheet 10 is first lifted, and the assembly plate 4 is inserted into the reserved slot 3. At this time, the wear-resistant sleeve 5 fixed in the inner ring of the assembly plate 4 is inside the through-hole 2. Since the assembly plate 4 is a "T"-shaped circular plate and the reserved slot 3 is a "convex" shaped circular opening, and the inner ring diameter of the assembly plate 4 is equal to the diameter of the through-hole 2, the assembly plate 4 can be smoothly inserted and fit into the reserved slot 3.
