A strain-type displacement sensor comprises a measuring rod, a sealing sleeve, a cylindrical outer shell, an amplifier plate, a strain gage plate, a push cone, a spring, a main support, and an output cable. The sensor of the utility model can be installed in the central position of a rear cover plate of an elevator brake through screw threads. The optimal installation position of the sensor can be determined by adjusting the screw thread screwing-in length. Amplified signals can be outputted directly through the amplifier plate. The sensor is characterized by small size, high precision, convenient installation, and the like, and is universally practical.
Description
Technical field
The utility model displacement transducer mainly is applicable to measurement and the monitoring of Mine Hoist Brake brake clearance, mine, belongs to engineering machinery field.
Background technology
At present, there are demand widely in real-time monitoring and measurement to various displacements in plant equipment, especially real-time monitoring and the measurement of mine Mine Hoist Brake brake clearance.For example " safety regulations in coal mine " regulation must check mine hoist and detent routine test, and the test-based examination content comprises retro-speed, damping force, brake clearance etc.Wherein, the 427th regulation: lifting gear must be installed the brake clearance protective device, when brake clearance surpasses the value of regulation, and can automatic alarm or auto-breaking.And regulation: brake shoe and the gap between brake disc of disc type brake should be not more than 2mm.At present, brake clearance is measured sensor used and mostly is the modes such as inductance type, Hall element, the equal volume of these modes is large, non-linear and disturb large, and can only be arranged between brake shell and brake shoe, this installation site is unreasonable, the data that can not truly reflect brake clearance, thereby measuring error is larger, is difficult to meet the requirement of test.
The utility model content
The purpose of this utility model is according to the weak point existed in prior art, provide a kind of easy for installation, simple in structure, measuring accuracy is high, antijamming capability is strong, be convenient to the novel displacement measurement sensor of safeguarding.
Strain-type sensor of the present utility model comprises sounding rod 1, sealing shroud 2, cylinder blanket 3, amplifier-chain plate 4, foil gauge plate 5, pushes away cone 6, spring 7, main body rack 8 and signal output cable 9, wherein at main body rack 8 front ends, sealing shroud 2 is installed, sounding rod 1 through sealing shroud 2 by displacement by spring 7, push away cone 6 and act on foil gauge plate 5, the strain signal that foil gauge plate 5 produces amplifies by 9 outputs of signal output cable through amplifier-chain plate 4.The sounding rod of sensor of the present utility model is pressing closer the stay-bolt in brake for lifting machine under the effect of spring, and along with the brake shoe seat moves together, sounding rod by spring, push away cone and act on the foil gauge plate, the foil gauge plate produces different strain signals along with pressure is different, this signal is directly proportional to displacement, the strain signal produced is output current or voltage signal after the amplifier plate amplifies, by detecting and process the variation that this signal can obtain displacement.
Preferably, the conehead that pushes away cone 6 is inserted in the hole at foil gauge plate 5 centers, adopts pin, pore structure to float and coordinates, and foil gauge plate 5 is arranged in the cell body of main body rack 8 bottoms, forms floating type installation and connects.This method of attachment can be eliminated the impact of extraneous stress, thereby guarantees that this sensor can accurately reflect the variation of displacement.
In addition, the appearance of cylinder blanket 3 is processed into threaded body, make sensor can be arranged on Mine Hoist Brake back shroud centre, sounding rod is pressing closer the stay-bolt in brake for lifting machine, can regulate screw thread precession length and determine the sensor optimum fixation position.
The utility model provides a kind of brake for lifting machine in addition, comprise brake shoe 14, back shroud 13, stay-bolt 12 and dish spring 11, it is characterized in that, above-mentioned strain-type sensor 10 is installed in the centre of back shroud, and the sounding rod of wherein said strain-type sensor is pressing closer the stay-bolt in brake for lifting machine.
Beneficial effect: strain-type sensor of the present utility model mainly is applicable to monitoring and the measurement of Mine Hoist Brake brake clearance, mine.This sensor construction is small and exquisite, easy for installation, measuring accuracy is high, antijamming capability is strong, has practicality widely.
