Description

Technical Field

[0001] The utility model relates to the field of transportation equipment, and more specifically to an easily replaceable lifting structure for a scrap steel chute. Background Art

[0002] The existing scrap steel chute lifting structure usually directly welds the trunnion on the outer wall of the scrap steel chute. The trunnion is the main load-bearing component connected to the hook. During long-term use, the part connected to the hook is easily worn, so it needs to be frequently inspected and replaced. However, the trunnion welded on the scrap steel chute will cause difficulty in disassembly during later replacement and maintenance, and the installation accuracy is not high. Moreover, the thermal stress generated by the welding part cannot be eliminated in time, which is prone to hidden dangers such as weld cracking. In addition, although the initial manufacturing cost of the welding structure is low, the later user use, maintenance and repair costs are high.

[0003] Therefore, how to provide a scrap steel chute lifting structure that is easy to disassemble and has a long service life is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0030] See also Figure 1 According to the embodiment of the utility model, the scrap steel chute easy-to-change lifting structure includes:

[0031] A suspension shaft seat 2 is fixed to the outer side wall of the side plate 3 of the scrap steel chute, and a conical mounting hole 21 axially perpendicular to the side plate 3 is provided on the suspension shaft seat 2;

[0032] The hanging shaft 1 includes a conical connecting portion 11 and a hanging portion 12 which are integrally connected. The conical connecting portion 11 is adapted to be inserted into the conical mounting hole 21 so that a conical self-locking structure is formed between the hanging shaft seat 2 and the conical connecting portion 11. The hanging portion 12 is fixed on the side of the conical connecting portion 11 away from the side plate so as to be connected to the hook.

[0033] A long cone self-locking structure is formed between the conical mounting hole 21 of the suspension shaft seat 2 and the conical connecting portion 11, so as to realize a tight connection between the suspension shaft seat 2 and the suspension shaft 1, and further realize a detachable connection between the suspension shaft 1 and the scrap steel chute. The suspension shaft 1 is easy to disassemble and assemble, and is convenient for later maintenance and repair.

[0034] In a specific example, the inner diameter of the tapered mounting hole 21 and the outer diameter of the tapered connecting portion 11 gradually decrease toward the end close to the side plate 3. Thus, a long tapered self-locking structure is formed between the suspension shaft 1 and the suspension shaft seat 2, thereby strengthening the firmness of the connection between the suspension shaft 1 and the suspension shaft seat 2.

[0035] Specifically, the taper of the tapered mounting hole 21 and the tapered connecting portion 11 is 1: 200. Thus, a long tapered self-locking structure is formed between the suspension shaft 1 and the suspension shaft seat 2, thereby strengthening the firmness of the connection between the suspension shaft 1 and the suspension shaft seat 2.

[0036] In some specific examples, an anti-slip baffle 4 is also included, a through hole is opened on the side plate 3 corresponding to the conical mounting hole 21, and one end of the conical connecting portion 11 close to the side plate 3 passes through the mounting hole and extends into the through hole, and a threaded blind hole 111 is provided on its end surface; the anti-slip baffle 4 can abut against the inner side wall of the side plate 3, and is threadedly connected to the threaded blind hole 111 on the end surface of the conical connecting portion 11 through the anti-loosening bolt 5. In this way, the firmness of the connection between the hanging shaft 1 and the scrap steel chute is further strengthened to prevent the hanging shaft from slipping out.

[0037] Specifically, the anti-slip baffle 4 includes an integrally connected plug-in portion 41 and a stop ring 42. One end of the plug-in portion 41 is plugged into the through hole. A threaded hole is provided on the plug-in portion 41 corresponding to the threaded blind hole 111, and the anti-loosening bolt can be threadedly connected with the threaded hole. The stop ring 42 is fixed to the outer wall of the other end of the plug-in portion 41, and its annular surface close to the plug-in portion 41 can abut against the inner wall of the side plate 3. In this way, the installation tightness of the anti-slip baffle 4 is enhanced to prevent it from moving in the radial and axial directions.

[0038] More specifically, a chamfer is provided on one side of the limiting ring 42 away from the plug-in portion 41. This helps the scrap steel to slide smoothly in the scrap steel chute.

[0039] In some specific examples, there are multiple anti-loosening bolts 5, multiple threaded blind holes 111 are evenly spaced circumferentially along the end surface of the conical connecting portion 11 close to the scrap steel chute, multiple threaded holes correspond to multiple threaded blind holes 111, multiple anti-loosening bolts 5 correspond to multiple threaded holes, and their tail ends pass through the threaded holes and are threadedly connected to the threaded blind holes 111. The hanging shaft 1 and the anti-slip baffle 4 are detachably connected, which is convenient for disassembly and assembly.

[0040] Specifically, the threaded hole is a countersunk hole, thereby protecting the anti-loosening bolt 5 and effectively preventing the anti-loosening bolt 5 from being hit or damaged when the scrap steel is loaded.

[0041] In some specific examples, an axial end baffle 6 is further included, and the axial end baffle 6 is fixed to the side of the hanging part 12 away from the tapered connecting part 11. Thus, the hook is prevented from moving along the axial direction of the hanging part 12, the stability during hoisting is improved, and the hoisting safety is ensured.

[0042] Working principle: The suspension shaft 1 and the suspension shaft seat 2 adopt a 1:200 long cone self-locking anti-drop structure, which is easy to disassemble and assemble, and is convenient for daily repair, maintenance and replacement. The shaft end baffle 6 is welded on the suspension shaft 1. The shaft end baffle 6 can prevent the hook from lateral displacement and causing the hook to be unhooked during the lifting process of the scrap steel chute body. The suspension shaft seat 2 is connected to the scrap steel chute body by welding. After the suspension shaft 1 and the suspension shaft seat 2 are installed and matched, they are connected to the scrap steel chute side plate 3 through the anti-drop baffle 4 and the anti-loosening bolt 5 to strengthen the tightness of the connection between the suspension shaft 1 and the scrap steel chute. The design of the countersunk hole on the anti-drop baffle 4 can effectively prevent the anti-loosening bolt 5 from being smashed and damaged when the scrap steel is loaded. When the suspension shaft 1 needs to be replaced or maintained, it is only necessary to remove the anti-drop baffle 4 and the anti-loosening bolt 5 to reversely pressurize and remove the suspension shaft 1 for replacement or steering.
