Abstract
Description
Technical Field
[0001] This utility model relates to a device for quickly changing the layer cold roller conveyor, belonging to the technical field of layer cold roller conveyors in hot-rolled strip steel production lines in the metallurgical industry. Background Technology
[0002] There are two ways to replace the layer cooling roller conveyor in a hot-rolled strip steel production line: The first is to directly hoist it within the travel range of the overhead crane, which takes about 20 minutes; the second is to move it outside the travel range of the overhead crane. Since the layer cooling roller conveyor is located below the instrument room, a fixed manual or electric mechanical hoist is needed to lift the layer cooling roller conveyor and move it within the travel range of the overhead crane. Due to the limited space below the instrument room, it is impossible to expand the working surface, which takes a long time, requiring 4-5 hours. This seriously affects production time and output, and increases production costs. There is an urgent need for equipment to solve this problem. Utility Model Content
[0003] The purpose of this invention is to provide a device for quickly replacing the cooling roller conveyor, which can conveniently and quickly replace the cooling roller conveyor outside the travel range of the overhead crane, reduce downtime, improve production efficiency, and solve the problems existing in the background technology.
[0004] The technical solution of this utility model is:
[0005] A device for quickly changing a layered cooling roller conveyor includes a counterweight, a fixed lifting lug A, a steel wire rope A, an adjusting lifting lug, a crossbeam, a fixed lifting lug B, and a steel wire rope B. The counterweight and the fixed lifting lug A are fixed at one end of the crossbeam, the fixed lifting lug B is fixed at the other end of the crossbeam, and the adjusting lifting lug is fixed in the middle of the crossbeam. There are two adjusting lifting lugs, which are symmetrically arranged on the upper and lower end faces of the crossbeam. The fixed lifting lug A and the upper adjusting lifting lug are connected by the steel wire rope A, and the lower adjusting lifting lug and the fixed lifting lug B are connected to both ends of the layered cooling roller conveyor by the steel wire rope B.
[0006] Furthermore, the adjusting lug is provided with several lifting holes. The lifting holes of the upper adjusting lug are matched with the wire rope A, and the lifting holes of the lower adjusting lug are matched with the wire rope B.
[0007] Furthermore, the fixed lifting lug A is located above the crossbeam, and the fixed lifting lug B is located below the crossbeam.
[0008] Furthermore, the fixed lifting lug A is provided with several lifting holes.
[0009] The beneficial effects of this utility model are: it enables convenient and quick replacement of the cooling roller conveyor outside the travel range of the overhead crane, reducing downtime and improving production efficiency. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the present invention;
[0012] In the diagram: counterweight 1, fixed lifting lug A2, wire rope A3, adjusting lifting lug 4, crossbeam 5, fixed lifting lug B6, layer cooling roller conveyor 7, motor 8, wire rope B9, lifting hole one 10, lifting hole two 11, ear plate 12. Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings and examples.
[0014] See attached document Figure 1-2 A device for quickly changing a layer-cooling roller conveyor includes a counterweight 1, a fixed lifting lug A2, a steel wire rope A3, an adjusting lifting lug 4, a crossbeam 5, a fixed lifting lug B6, and a steel wire rope B9. The counterweight 1 and the fixed lifting lug A2 are fixed to one end of the crossbeam 5. The fixed lifting lug A2 is fixed to the upper end face of the crossbeam 5. The fixed lifting lug B6 is fixed to the lower end face of the other end of the crossbeam 5. The adjusting lifting lug 4 is fixed in the middle of the crossbeam 5. There are two adjusting lifting lugs 4, which are symmetrically arranged on the upper and lower end faces of the crossbeam 5, respectively. The fixed lifting lug A2 and the upper adjusting lifting lug 4 are connected by the steel wire rope A3. The lower adjusting lifting lug 4 and the fixed lifting lug B6 are respectively connected to the two ends of the layer-cooling roller conveyor 7 by the steel wire rope B9.
[0015] The adjusting lug 4 has several lifting holes 10. The upper adjusting lug 4 has several lifting holes 10 that engage with wire rope A3, while the lower adjusting lug 4 has several lifting holes 10 that engage with wire rope B9. By adjusting the position of wire rope A3 at the corresponding lifting holes 10 of the upper adjusting lug 4, the lifting point of the overhead crane can be varied. By adjusting the position of wire rope B9 at the corresponding lifting holes 10 of the lower adjusting lug 4, different lengths of chilled roller conveyors can be lifted.
[0016] The upper adjusting lug 4 has several lifting holes 10 with matching ear plates 12. The position of the ear plates 12 can be adjusted for connection with the wire rope A3.
[0017] The fixed lifting lug A2 is provided with several lifting holes 11 for adjusting the position of the wire rope A3.
[0018] In this example, refer to the appendix. Figure 1-2The device includes a counterweight 1, fixed lifting lugs A2, wire ropes 3, adjusting lifting lugs 4, a crossbeam 5, and fixed lifting lugs B6. The crossbeam 5 has a total length of 4.65 meters, and the counterweight 1 weighs approximately 0.8 tons, used to ensure the roller conveyor is in a horizontal position during the lifting process. Fixed lifting lugs A2 are welded to the top of the crossbeam 5, and fixed lifting lugs B6 are welded to the bottom of the crossbeam 5. There are two adjusting lifting lugs 4, symmetrically arranged on the upper and lower ends of the crossbeam 5.
