Split type oil cylinder connecting device

Abstract

The utility model relates to the field of slab continuous casting machine equipment, in particular to a split type oil cylinder connecting device. The device comprises an oil cylinder support, and a pin shaft is arranged on the oil cylinder support. The oil cylinder support is of a split structure and comprises two upper covers and a lower base, and each upper cover is fixed to the lower base through an upper countersunk bolt and a lower countersunk bolt. The upper cover is provided with a boss and is provided with a groove corresponding to the lower seat, so that a concave-convex joint surface is formed when the upper cover and the lower seat are assembled. During point inspection, the pin shaft and the four bolts shielded by the flat head can be subjected to point inspection and maintenance only by detaching the four bolts on the upper cover and taking down the upper cover, so that the point inspection and maintenance time is greatly shortened, equipment accidents are avoided, the structure is reasonable, and stable operation of slab continuous casting machine pendulum shear equipment is ensured.

Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plate blank continuous casting machine equipment, namely split type oil cylinder connecting device. BACKGROUND

[0002] In the prior art, the steel plant steelmaking plate blank continuous casting machine swing shear balance oil cylinder support is integrally designed, four bolts are used to fasten the support on the swing shear blade, the balance oil cylinder flat head is connected with the support through a pin shaft, the four fastening bolts are completely blocked by the oil cylinder flat head, the pin shaft needs to be disassembled, the oil cylinder flat head is shifted, and then the bolts can be checked, the pin shaft, the flat head and the support are assembled with interference, and it takes about 10 hours to disassemble and reassemble, under the condition that the production rhythm is tense, there is no time to disassemble the pin shaft and check the bolts, during the long-time operation of the swing shear, the bolts are loose and even worn, resulting in a gap between the support and the shear blade connection part, the four bolts are broken under stress during the shearing process of the swing shear, and the plate blank production is affected. SUMMARY

[0003] The utility model aims at the above-mentioned insufficient and provides a split type oil cylinder connecting device which is reasonable in structure, convenient to disassemble and improves the point inspection and maintenance efficiency of the bolts and the pin shaft.

[0004] The technical solution of the utility model is as follows: a split type oil cylinder connecting device, comprising an oil cylinder support, wherein a pin shaft is arranged on the oil cylinder support.

[0005] Two lifting rings are arranged on the lower seat.

[0006] The utility model has the advantages that the original integral oil cylinder support is cancelled, the split type oil cylinder connecting device is redesigned and manufactured, the main body is divided into two parts, that is, two upper covers and a lower seat, four high-strength countersunk head bolts are used to fix the two upper covers on the lower seat, the lower seat is connected with the shear blade through four high-strength countersunk head bolts, during the point inspection, the four bolts of the upper cover are disassembled, the upper cover is removed, the pin shaft and the four bolts blocked by the flat head can be inspected and maintained, the inspection and maintenance time is greatly shortened, equipment accidents are avoided, and the structure is reasonable and convenient to disassemble.

[0007] The embodiments of the utility model will be further described in detail below with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0014] Referring to Figures 1-5 , split oil cylinder connecting device, oil cylinder support adopts split structure, that is two upper covers 1 and lower seat 2, each upper cover 1 is fixed on lower seat 2 by two countersunk bolts 4 in upper and lower positions; upper cover 1 is in the form of boss, corresponding lower seat 2 is with groove, so that upper cover 1 and lower seat 2 form concave-convex joint surface when assembling, which is well matched and ensures the assembly stability. Two lifting rings 3 are installed on lower seat 2, which facilitates hoisting.

[0015] Two upper covers 1 are fixed on lower seat 2 by four high-strength countersunk bolts 4, pin shaft 5 is fixed in split oil cylinder connecting device together with flat head 7, oil cylinder flat head 7 blocks four fastening countersunk bolts 6, upper cover 1 and lower seat 2 are assembled to form pin hole 9 and concave-convex joint surface 8. During maintenance, only four countersunk bolts 4 need to be removed to displace pin shaft 5 and flat head 7, then fastening countersunk bolt 6 and pin shaft 5 are checked and replaced, and the disassembly and assembly only need 0.2 hours, which greatly shortens the time of point inspection and maintenance, avoids equipment accidents, has reasonable structure, is convenient to disassemble and assemble, and ensures stable operation of the plate blank shearing equipment. The split oil cylinder connecting device is made of Q345 material, has the characteristics of high toughness and high tensile strength.

[0016] The above description is only a specific embodiment of the utility model, and various examples do not constitute limitation on the essential content of the utility model.
