Embodiment Construction

[0045] Figure 1 is a structural sectional schematic diagram of Embodiment 1 of a hydraulic cylinder displacement sensor placed in the lifting lug of the present invention;

[0046] The hydraulic cylinder includes a hydraulic cylinder body 1 , a lifting lug 8 , a piston 18 and a displacement sensor; the lifting lug 8 is fixed at one end of the hydraulic cylinder 1 .

[0047] The displacement sensor includes a displacement sensor rotation assembly, a displacement sensor measurement assembly and a spring 14 .

[0048] The displacement sensor rotating assembly is connected with the piston 18, and the spring controls the movement of the piston through the matching connection with the displacement sensor rotating assembly. The displacement sensor measuring assembly cooperates with the displacement sensor rotating assembly to measure the displacement stroke of the piston 18.

[0049] The displacement sensor rotating assembly also includes a rotor 9, a rotating main shaft 6 and a cabl...

Abstract

The invention relates to a displacement sensing device for measuring the piston strokes within hydraulic cylinders, and it particularly relates to a built-in displacement sensing device of hydraulic cylinders with lifting eyes. The said displacement sensor comprises displacement rotation components for sensors, measuring components for displacement sensors and springs. The displacement sensor components mate with springs to control the movement of the piston, and they also mate with displacement sensor measuring components to measure the displacement strokes of the pistons, with the displacement sensor rotation components connected with pistons. The inventions is meant to solve the technical issues like the those caused by the external displacement sensor, and also the defect of lacking built-in opening checkup devices of those hydraulic cylinders with lifting eyes. With this structure, the invention has high precision of measurement and convenient way for installation and maintenance.

Description

Technical field: [0001] The invention relates to a displacement sensing device for measuring the stroke of a piston in a hydraulic cylinder, in particular to a built-in displacement sensor in a hydraulic cylinder containing lifting lugs, which is used in conjunction with the hydraulic cylinder and detects its operation control device. Background technique: [0002] With the continuous development of water conservancy, in various hydraulic structures of water conservancy and hydropower projects, various gates with different performances and types are installed according to functional requirements to meet the needs of various operating conditions. Among them, the operation reliability of emergency gates and working gates in buildings such as flood discharge, power generation and water diversion, and navigation are directly related to the safety and efficiency of the project, and the equipment for opening and closing gates is extremely demanding; on the other hand, these emerge...
