Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgical installation, in particular to a trolley device for disassembling and assembling bending blocks of a plate coil rolling mill. Background Art
[0002] At present, in order to improve the rolling function, the plate and coil rolling mill needs to transform and upgrade the bending blocks of the rolling mill's working rolls. With the development of the metallurgical industry and the construction of repair and reconstruction projects, the disassembly and assembly of the on-site rolling mill's working roll bending blocks is the focus of the construction. The disassembly and assembly cycle directly determines the length of time the rolling mill will be shut down, and indirectly affects the production efficiency of the rolling mill.
[0003] Since the bending and shifting roll device components are inside the rolling mill, when disassembling and assembling, the old components need to be transported to the outside of the rolling mill and the new components need to be transported to the inside of the rolling mill, or the defects of the old components need to be processed and then put back into the rolling mill. Since the internal space of the rolling mill is small and the components are heavy, they cannot be moved manually. The existing technology often uses a hand winch or other lifting machinery to gradually transport the roll bending and shifting blocks back and forth. The transportation process is very cumbersome and time-consuming, the labor intensity of the workers is increased, and the transportation process is prone to tilting, resulting in unsafe transportation.

[0006] Furthermore, there are at least two bases, the multiple bases are kept parallel, located on a straight line, and symmetrically distributed around the center of the vehicle floor, and each of the bases is fixedly connected to a fixing bracket column.
[0007] Furthermore, the fixed support column adopts a 200×200H-shaped steel fixed support column.
[0008] Furthermore, the bending block is fixed to the fixed column by bundling with a flat belt.
[0009] Furthermore, the vehicle floor and the base are both made of steel plates.

A trolley with fixed bracket columns is fixed on the vehicle bottom plate through a base, which can be moved on the rolling mill track, and can conveniently transport the tooling roll bending blocks to be disassembled and installed. The utility model is suitable for the disassembly and assembly and reverse transportation of the bending blocks of medium-sized rolling mills with a width of 1000-2500. When in use, it is only necessary to push the trolley into the rolling mill, place the disassembled roll bending blocks on the trolley and then transport them out of the track, and then place the roll bending blocks to be installed on the trolley, and reversely transport them to the rolling mill for installation and replacement by the trolley, thereby replacing the previous cumbersome and unsafe reverse transportation method, simplifying the disassembly and assembly and reverse transportation process of the tooling roll bending blocks of the rolling mill, saving reverse transportation and replacement time, and improving the disassembly and reverse transportation efficiency.

[0022] The present invention will be further described in detail below in conjunction with specific embodiments and drawings, which are intended to explain the present invention rather than to limit it.
[0023] like Figure 1 , Figure 2 As shown in the figure, the plate coil rolling mill bending block disassembly and assembly trolley device of the utility model comprises a vehicle bottom plate 1, wheels 2, a base 3 and a fixed bracket column 4 for fixing the bending block. The vehicle bottom plate 1 and the base 3 are both made of steel plates. The design size of the vehicle bottom plate 1 is 4240mm×1600mm×20mm. The vehicle bottom plate 1 is parallel to the rolling mill track. The wheels 2 are installed at the bottom of the vehicle bottom plate 1. The design size of the wheels 2 is a wheel surface width of 60mm and a diameter of 140mm. There are at least 6 wheels 2. The wheels 2 are adapted to the rolling mill track. The wheels 2 roll along the axial direction of the rolling mill track to drive the vehicle bottom plate 1 to move so as to transport the bending block; the base is fixedly installed on the upper end surface of the vehicle bottom plate 1 3. The design size of the base 3 is 400mm×400mm×25mm. The base 3 is vertically connected with the fixed support column 4. Specifically, there are at least two bases 3, and the multiple bases 3 are kept parallel, located in a straight line, and symmetrically distributed with the center of the vehicle bottom plate 1. Each of the bases 3 is fixedly connected with a fixed support column 4. The fixed support column 4 adopts a 200×200H-shaped steel fixed support column. The 200×200H-shaped steel fixed support column is made of high-quality steel, which can easily withstand a large amount of load and pressure, ensure stability and safety, and is suitable for the disassembly and assembly of the bending block of a medium-sized rolling mill with a width of 1000-2500. Figure 3 , Figure 4 , Figure 5 As shown in Figure 3 The direction of the middle arrow indicates the rolling direction on the entrance side. The wheel 2 drives the vehicle floor 1 to move along the rolling mill track to the bending blocks that need to be disassembled and assembled, such as the entrance side bending block A and the exit side bending block B. Taking the entrance side bending block A as an example, the entrance side bending block A is placed on the vehicle floor 1 for transportation. During transportation, the bending block is securely tied to the fixed bracket column 4 with a flat belt 5 with a width of 30 mm to ensure that it will not tip over during transportation, thereby ensuring the stability and safety of transportation.
[0024] Working principle: When the utility model is in use, the trolley is pushed into the rolling mill track, and the wheels 2 move along the rolling mill track, driving the bottom plate 1 to move to the disassembled roll bending block, and the disassembled roll bending block is placed on the bottom plate 1, and the disassembled roll bending block is tied and fixed on the fixed bracket column 4 with a 30mm flat belt 5 to ensure safe and stable transportation. The disassembled roll bending block is then transported out by the trolley, the flat belt 5 is untied to remove the roll bending block, and the roll bending block to be installed is placed on the bottom plate 1 of the trolley, and fixedly tied to the fixed bracket column 4 with the flat belt 5, and then transported to the installation site by the trolley for installation and replacement, replacing the previous cumbersome, high-intensity, and unsafe transportation method, simplifying the disassembly, assembly and transportation process of the rolling mill tooling roll bending block, saving transportation and replacement time, improving the disassembly and transportation efficiency, and the transportation process is safe and stable.
