Steel ladle sliding plate hydraulic cylinder driver with positioning function

Abstract

The invention discloses a steel ladle sliding plate hydraulic cylinder driver with a positioning function, and relates to the field of steelmaking equipment. The steel ladle sliding plate hydraulic cylinder driver with the positioning function comprises a rack, a lower moving frame connected to the bottom of the rack in a sliding mode, a heat insulation sliding plate connected with the bottom of the lower moving frame and a hydraulic cylinder used for driving the lower moving frame to move along the rack, and further comprises a driver body. A hydraulic rod of the hydraulic cylinder penetrates through the driver in a sliding mode and then is connected with the lower moving frame, a positioning block is arranged on the hydraulic rod in a protruding mode, limiting blocks located on the moving track of the positioning block are arranged at the two ends of the inner wall of the driver respectively, a lower reference check block is connected to the bottom of the driver, and the bottom of the lower reference check block extends to be located on the same horizontal plane with the heat insulation sliding plate. According to the steel ladle sliding plate hydraulic cylinder driver with the positioning function, an operator can conveniently confirm the position of the heat insulation sliding plate, and potential safety hazards caused by separation of the hydraulic cylinder and the driver after long-time operation are prevented.

Description

technical field [0001] The present application relates to the field of steelmaking equipment, in particular, to a hydraulic cylinder driver for a ladle slide plate with a positioning function. Background technique [0002] As the main component of ladle flow control, the ladle sliding plate mechanism plays an important role in the safe operation of the ladle. The ladle sliding plate mechanism mainly includes a frame, a lower moving frame slidably connected to the bottom of the frame, a heat insulation slide connected to the bottom of the lower moving frame, and The hydraulic cylinder is used to drive the lower moving frame to move along the frame. The frame is fixedly connected to the bottom sandwich panel of the ladle. The hydraulic cylinder drives the lower moving frame to slide along the frame to drive the heat-insulating slide to move and control the flow.

Problems solved by technology

[0003] As a functional component of ladle flow control, the heat insulation slide plate plays an important role in the safe operation of the ladle machinery. When the ladle cannot be opened by itself, it will be forced to generate oxygen drainage. When the oxygen drainage is driven by the hydraulic cylinder, the frame will be moved In order to control the flow with the heat insulation slide plate moving in place, it is required that the drainage personnel communicate with the slide plate operator in place. At this time, the operator has to confirm with the slide plate switch personnel whether the heat insulation slide plate is fully open in an environment with fast production rhythm and psychological stress. There is a phenomenon that the heat insulation slide is burnt when the heat insulation slide is not fully turned on to burn oxygen. After the heat insulation slide burns through, the flow control of the slide will lose its function, which will eventually lead to safety accidents; the tonnage of the ladle depends on the ladle slide mechanism frequently. The hydraulic cylinder and the driver rely on hard connections, and frequent switching may easily cause the hydraulic cylinder and the driver to slip, which may easily lead to production interruption and safety accidents.
