Vertical roller cardan shaft safety device and using method

Abstract

The invention provides a vertical roller cardan shaft safety device and a using method, after a cardan shaft is supported by a bracket, safe locking protection of the cardan shaft bracket is achieved through an interlocking mode of components such as an electric cylinder, a proximity switch and an electric mortise lock, potential safety hazards caused by oil leakage and pressure loss of a hydraulic cylinder are avoided, the safety of operators in operation is ensured, due to the introduction of an electric control mode, the process of manually climbing to install a safety clamping plate is omitted, and the danger of high-place operation is reduced.

Description

technical field [0001] The present application relates to the technical field of safety devices for metallurgical equipment, in particular to a safety device for a vertical roll cardan shaft and a method of use thereof. Background technique [0002] In the bar and wire processing production line, the vertical rolling mill is commonly used equipment. In order to ensure the quality and rolling efficiency of the rolled piece, it is necessary to replace the roll when the roll is damaged. The transmission of the vertical roll is mainly connected by the cardan shaft. In the process of replacing the roll, the roll needs to be separated from the cardan shaft, and the cardan shaft needs to be supported by a hydraulic bracket to prevent it from falling. In the prior art, there is also a bracket that is blocked by a safety clamp to prevent it from falling. [0003] However, in long-term use, it has been found that the traditional vertical rolling mill cardan shaft bracket, due to the...

Problems solved by technology

[0003] However, in long-term use, it has been found that the traditional vertical rolling mill cardan shaft bracket, due to the leakage of the hydraulic system during the roll change process of the traditional vertical rolling mill, will cause insufficient pressure in the hydraulic cylinder, and the loss of pressure in the hydraulic cylinder during the operation will cause the bracket to be damaged. Open, causing the cardan shaft to fall, causing a safety accident

And the safety card board also has the situation that it is difficult to buckle the bracket during the pressure loss process due to the low radian and dimensional accuracy.

Moreover, due to the high height of the vertical rolling mill, when installing the safety clamp, it is necessary to perform climbing operations, which puts the operators in a dangerous situation

[0004] It can be seen that the use of the traditional vertical rolling mill cardan shaft bracket faces many risks, which affects the smooth progress of production, and equipment accidents may occur, and may cause injuries to operators at the same time
