Self-locking and self-unlocking type hanging hook device for replacing fan-shaped section

Abstract

The invention discloses a self-locking and self-unlocking type hanging hook device for replacing a fan-shaped section. The self-locking and self-unlocking type hanging hook device comprises a hanging hook, a self-locking hydraulic cylinder, a self-locking pushing block, an ejection hydraulic cylinder, a connecting rod mechanism and a pushing wheel, wherein the self-locking hydraulic cylinder is fixed above a hook opening of the hanging hook; the self-locking pushing block is connected with a piston rod of the self-locking hydraulic cylinder; the ejection hydraulic cylinder is fixed on the side surface of the hanging hook; one end of the connecting rod mechanism is connected with a piston rod of the ejection hydraulic cylinder, and the other end of the connecting rod mechanism is connected with the pushing wheel; the connecting rod mechanism is connected with the hanging hook; the self-locking hydraulic cylinder and the ejection hydraulic cylinder are connected with a control system; and the piston rods of the self-locking hydraulic cylinder and the ejection hydraulic cylinder are controlled by the control system to extend and shrink. The self-locking and self-unlocking type hanging hook device has the beneficial effects that the automation degree and reliability of the fan-shaped section of a continuous casting machine in the replacement process are improved; the dangerousness of manual operation is reduced, a potential safety hazard is avoided, the hoisting time is shortened, the replacement period of the fan-shaped section is shortened, the production cost is reduced, and the production efficiency is improved; the self-locking hydraulic cylinder and the ejection hydraulic cylinder can be remotely regulated; and the self-locking and self-unlocking type hanging hook device is simple and compact in structure, and convenient to control.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, in particular to a segment replacement device for a slab continuous casting machine. Background technique [0002] The segment is the key equipment of the continuous casting machine, and the segment is one of the equipment that needs to be replaced more frequently in the continuous casting machine. Therefore, each continuous casting machine needs to be equipped with a special segment replacement device, so that the segment can be replaced conveniently and quickly, so as to shorten the maintenance cycle of the continuous casting machine, improve production efficiency, and increase the output of slabs. [0003] The segment replacement of the traditional continuous casting machine is to replace the segment by means of the workshop crane and the replacement guide rail of the segment. The shortcomings of the traditional replacement method are: manual operation is required when lifting and unhoo...

AI Technical Summary

Problems solved by technology

The shortcomings of the traditional replacement method are: manual operation is required when lifting and unhooking, and the hook has no self-locking function during the lifting process, which has certain potential safety hazards; since the fan section is located under the platform of the continuous casting machine, it belongs to the crane workers in the workshop. Blind area of ​​vision, high risk and low work efficiency

If the existing continuous casting machine is to be modified, due to the height limitation of the original plant, the crane will not be able to lift and replace the segment

[0004] In order to solve the shortcomings of the traditional technology, the patented technology named "Sector Replacement Tool for Automatic Conversion Constraints for Continuous Casting Machine" (application number ZL201120568248.X) provides a segment replacement tool. The shortcoming of this patent technology is that the structure Complex, light lifting weight, and manual operation of the locking mechanism, unable to remotely control the self-locking and opening of the hook
