Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting machines, in particular to a fork head device for rapid disassembly and assembly of a segment of a continuous casting machine. Background Art

[0002] A slab continuous casting machine mainly relies on the connection between segments of the segment to achieve multi-point bending and multi-point straightening, ensuring continuous productivity, shaping of the cast slab, cold cutting of the cast slab, and improvement of internal quality.

[0003] The segment is divided into upper and lower parts (the upper part is the inner arc frame and the lower part is the outer arc frame), and the hydraulic cylinder provides a force to cause the upper part (inner arc) to move, giving a downward force to the cast slab to prevent the cast slab from bulging, avoiding internal looseness of the cast slab, and ensuring the quality of the cast slab.

[0004] The segment is used in a harsh environment with high temperature, high humidity, and high-intensity force. Especially when the segment is put into soft reduction, the downward pressure on the upper part (inner arc) is relatively large. The fork head is the "bridge" connecting the upper and lower parts (the installation position is as shown), and both the hydraulic cylinder force and the reaction force are directly transmitted through the fork head, with relatively high strength requirements. Figure 1 As shown), and both the hydraulic cylinder force and the reaction force are directly transmitted through the fork head, with relatively high strength requirements.

[0005] Due to the fact that the original fork head design did not consider the harsh on-site use environment, it often becomes severely rusted after being used for a period of time. The fork head and the cylinder head are stuck together due to rust and cannot be disassembled. If the cylinder needs to be replaced, the disassembly difficulty is very high. The fork head can only be cut off little by little. Such work not only has low efficiency, but also causes damage to the installation teeth of the cylinder, increasing the construction difficulty and the workload, and the efficiency cannot be guaranteed. Summary of the Invention

[0006] The purpose of the utility model is to solve the above problems and provide a fork head device for rapid disassembly and assembly of a segment of a continuous casting machine. This fork head device can not only be firmly connected to the segment, has high use strength, but also can be quickly disassembled and assembled, ensuring that the utility model can be reused repeatedly, reducing the manual labor intensity, saving spare part costs, and improving work efficiency.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] A fork head device for rapid disassembly and assembly of a segment of a continuous casting machine, comprising a first connecting part and a second connecting part. One end of the first connecting part is integrally formed with one side of the second connecting part. The end of the first connecting part far from the second connecting part is connected to an oil cylinder on the inner arc frame of the segment. A through groove communicating with the oil cylinder push rod is formed on one side of the first connecting part, and the opening size of the through groove is 25 - 28 mm. A groove penetrating through the second connecting part and extending to the first connecting part is formed on the second connecting part, and the second connecting part is connected to the outer arc frame of the segment through a connecting plate inserted into the groove.

[0009] In the present utility model, further, the first connecting part is a trapezoid-like body, and the second connecting part is a semi-cylinder-like body.

[0010] In the present utility model, further, a counterbore through hole penetrating the through groove is formed on the trapezoid-like body to tighten the trapezoid-like body through a screw inserted into the counterbore through hole.

[0011] In the present utility model, further, the diameter of the counterbore through hole is 26 mm.

[0012] In the present utility model, further, a first oil injection hole is formed at one end of the trapezoid-like body close to the semi-cylinder-like body.

[0013] In the present utility model, further, the diameter of the first oil injection hole is 20 mm.

[0014] In the present utility model, further, a second oil injection hole is formed at one end of the trapezoid-like body far from the semi-cylinder-like body.

[0015] In the present utility model, further, the diameter of the second oil injection hole is 16 mm.

[0016] Due to the adoption of the above technical solution, the present utility model has the following beneficial effects:
