Displacement is not easy to the working condition that detection maintenance personnel understands compensator in real time without intuitive display.
A kind of device of 104677466 measuring compensator axial displacements of Chinese patent CN discloses underwater robot compensation
Device displacement detecting sensor and its detection method, the present invention relates to underwater robot compensator displacement detecting sensor, including work
Plug, movable support and fixing bracket, watertight socket, stainless steel cylinder and its internal circuit board set；One end of piston is fixed on
In compensator on movable end cover, the other end is fixed with movable support；The fixation set on stainless steel cylinder one end and compensator housing
Stent is fixedly connected, and the other end is placed in movable support；The watertight socket and host computer that circuit board passes through stainless steel cylinder end
Connection.Its method is calibration adjustable potentiometer resistance value；When the movable end cover movement of compensator, band piston and movable support
On magnet ring movement, the signal end of some Hall element in stainless steel cylinder in magnet ring magnetic field range leads with power supply ground terminal
Logical, for detection circuit output detection voltage to host computer, host computer obtains corresponding compensator displacement according to the voltage.Present invention knot
Structure is simple, and autgmentability is strong, and reliability is high, is suitable for oily compensator displacement or the oil mass detection of various underwater equipments.
Although the technical solution of the patent shows the deformation of nose balance product to go a step further, but there are the following problems：
1）Axial displacement can only be measured, it is impossible to measure lateral displacement deformation, above-mentioned technical proposal lacks universal adaptability；2）Measurement structure
Complexity, installation are inconvenient.
Utility model content
The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art provides a kind of compound drawing of measurement
The device of rod-type expansion joint lateral displacement, it is simple in structure, versatile, measure accurate, wide range of measurement, prison in real time can be achieved
It surveys.
In order to solve the above technical problems, the utility model provides a kind of compound pull rod type expansion joint lateral displacement of measurement
Device, compound pull rod type expansion joint include at least two expansion joints, and tested compound pull rod is mounted on including 90 ° at least with phase angle
A pair of of sensory package on type expansion joint, a pair of of sensory package contain equal to compound pull rod type expansion joint axial line distance respectively
First and second displacement sensors, sensory package further include two sensings that outer end is separately fixed on two pipe nipple of FlexbleJoint
Device mounting bracket, the inner end of two sensors mounting bracket are hinged respectively with corresponding displacement sensor both ends by flexural pivot head, and displacement passes
The extending direction of sensor is parallel with the initial axis of compound pull rod type expansion joint.The transducing signal output termination object of displacement sensor
The signal input part of networking monitoring system.
The technical solution that the utility model further limits is：
Further, the first and second displacement sensors are mounted on any one place's ripple compensation of compound pull rod type expansion joint
On device.
