Abstract
Description
Technical Field
[0001] This invention relates to the field of blast furnace ironmaking equipment, and more specifically, to a wire rope tensioning device for a material car. Background Technology
[0002] In blast furnace ironmaking, hoists and charging cars are usually used for charging. The charging car is a key piece of equipment. If the charging car malfunctions, it can cause the blast furnace to stop charging and production, or even lead to a safety accident.
[0003] In existing technologies, the traction device for material carts generally uses double steel wire rope traction to increase the safety factor, such as... Figure 1 As shown, the wire rope (C) is directly connected to the crossbeam (A) through the tie rod (B). However, the total length of the wire rope (C) of the material cart is nearly 200 meters. There are errors in the normal installation, which causes the tension of the two wire ropes (C) to be inconsistent. In actual use, only one wire rope (C) is under force. Over time, this will not only affect the life of the wire rope (C) but also reduce the traction safety factor of the wire rope (C), causing the material cart to deviate. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art. The purpose of the present invention is to provide a wire rope tensioning device for a material cart that can automatically adjust the tension of two wire ropes.

Between the first and third balance plates, the first fork-shaped component is located between the second and fourth balance plates, and the first and second fork-shaped components are located close to each other. One end of the first and third balance plates is rotatably connected to the first and second connecting plates via a fourth pin. The middle part of the first and third balance plates is rotatably connected to the first and second crossbeams via a third pin. The other end of the first and third balance plates is rotatably connected to one end of the second fork-shaped component. One end of the second and fourth balance plates is rotatably connected to the first and second connecting plates via a first pin. The middle part of the second and fourth balance plates is rotatably connected to the first and second crossbeams via a second pin. The other end of the second and fourth balance plates is rotatably connected to one end of the first fork-shaped component.

[0011] Beneficial effects
[0012] Compared with the prior art, the advantages of this invention are as follows:
[0013] This invention achieves automatic adjustment of the tension of two steel wire ropes by installing two triangular balance plates, thus avoiding the situation where only one steel wire rope is under force due to inconsistent tension between the two steel wire ropes.
[0014] The wire rope is automatically tensioned, which improves the safety factor of the wire rope.
[0015] When the two steel wire ropes are evenly stressed, the problem of the material car running off-center due to unbalanced traction is avoided. Attached Figure Description

[0029] Working principle:
[0030] During operation, when the second wire rope 62 is slack, the first wire rope 61 experiences greater force. The first wire rope 61 drives the first pull rod 51 and the first fork-shaped member 41 to move to the left. The first fork-shaped member 41 drives the second balance plate 22 and the fourth balance plate 24 to rotate counterclockwise. The second balance plate 22 and the fourth balance plate 24 then drive the first connecting plate 31 and the second connecting plate 32 to move downward. At the same time, the first connecting plate 31 and the second connecting plate 32 drive the first balance plate 21 and the third balance plate 23 to rotate counterclockwise, thereby driving the second fork-shaped member 42, the second pull rod 52, and the second wire rope 62 to move to the right, tightening the second wire rope 62, thus realizing the automatic tensioning function of the wire rope.
