Device and method for measuring levelness of piston of gas chamber

Abstract

The invention relates to a device for measuring the levelness of a piston of a gas chamber. The device comprises four contactless measuring instruments, four reflection plates and one set of PLC (Programmable Logic Controller) control device, wherein the four contactless measuring instruments are arranged at the top surface of the gas chamber at equal intervals and are connected to the PLC control device; distances between the four contactless measuring instruments and the top surface of the gas chamber are equal; and the four reflection plates are arranged on the piston and are arranged corresponding to the four contactless measuring instruments. The invention further relates to a method for measuring the levelness of a piston of a gas chamber. The four contactless measuring instruments are arranged at the top surface of the gas chamber at equal intervals,; therefore, the defect that a signal cable needs to be laid inside the gas chamber in a conventional measuring method is effectively solved, and the positive functions of reducing the accident rate, saving the construction investment and increasing the labor productivity are achieved; and meanwhile, the levelness of the piston of the gas chamber can be determined only through the PLC control device, and the device is simple in structure and convenient to operate and control.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for the levelness of a gas cabinet piston, which are applied to gas technology. Background technique [0002] At present, the measurement of the levelness of the gas cabinet piston is an important means to ensure the normal and safe production and operation of the gas cabinet. [0003] For coke ovens or blast furnace gas holders with thin oil seals, the piston level measurement method is to install four sets of liquid level measuring instruments at equal intervals on the oil grooves around the pistons to measure the oil level heights in the piston oil grooves respectively. Calculate the oil level height difference of the piston oil groove measured by the two liquid level measuring instruments installed symmetrically with the center of the cabinet body, so as to determine the levelness of the gas cabinet piston. [0004] For converter gas cabinets with rubber membrane seals, the piston ...

AI Technical Summary

Problems solved by technology

However, when the piston rises or falls, the cable may be entangled, knotted, or even torn off, seriously affecting the normal and safe production and operation of the gas cabinet.

In addition, laying signal cables inside the cabinet and setting up cable storage boxes also increase the difficulty and workload of construction and increase the cost of installation and construction.
