Description
Technical field
The utility model relates to a kind of built-in lasting high accuracy displacement sensor.
Background technology
At present, a kind of jaw opening sensor that in power station and hydrographic survey, uses, on the hanger that jaw opening sensor is installed in hydraulic cylinder links to each other, comprise a cord winder in the jaw opening sensor, this cord winder has formations such as flange bracket, reel, spring housing, spring, scrambler, wiring unit, reel and wiring unit are installed in the support by axle, and spring housing's (spring is installed in the spring housing) and scrambler are installed in two ends of spool shaft, are positioned at the hanger outside.This cord winder can only carry out one deck serving winding operation, if carry out multiple wraps when operation, because more than two layers during serving, the uncertainty that rope is arranged, its winding precision reduces greatly after the second layer; In order to improve measuring accuracy, generally be that the diameter that amplifies reel increases measurement range, cause the cord winder volume big, inconvenience is installed, increased installing space, influenced the bulk strength of hanger.
Summary of the invention
The purpose of this utility model: it is little to design a kind of volume, the built-in lasting high accuracy displacement sensor that measuring accuracy is high.
The technical scheme that its technical matters that solves the utility model adopts is:
Built-in lasting high accuracy displacement sensor, comprise part hanger, rope drum, spring, scrambler, pressure rope wiring unit, measurement wheel, displacement rope, soft connection, the hanger below is connected with hydraulic cylinder and piston, one cavity body is arranged on hanger, spring is connected the outside of the transmission shaft of rope drum, rope drum is installed on hanger cavity body top, series arrangement is equipped with the measurement wheel of rope drum parallel axes and presses the rope wiring unit below rope drum, is connected with scrambler at an end of measurement wheel axial line.
Displacement rope one end is fixed on the piston, by being connected with the holding with rope drum of flute profile of pressing rope wiring unit, measurement wheel and pressure rope wiring unit, by the pulling force of spring, realizes that the displacement rope is solid on rope drum in the multiple wraps on the rope drum and the other end.Wherein measurement wheel can endwisely slip along direction of axis line, presses the rope wiring unit also can endwisely slip along direction of axis line,
In the such scheme, the effect of rope drum is can multilaminate coiled displacement rope, the effect of measurement wheel is the straight-line displacement of rotating metering piston, when the displacement rope is wound up on the rope drum through overvoltage rope wiring unit, measurement wheel, press the rope wiring unit that the displacement rope is close on the measurement wheel flute profile, increase the cornerite of displacement rope and measurement wheel, rope drum displacement rope in the process of serving must pass through measurement wheel, on rope drum, can twine multilayer displacement rope, on the rope drum of equal volume, increased considerably measurement length, have the spring of reset response to be installed in the hanger outside, dwindled the volume of rope drum greatly, the displacement rope of process measurement wheel is definite value always, the stroke of energy high-acruracy survey piston, volume is little, and the measuring accuracy height has reached the purpose of this utility model.
Beneficial effect is, can realize multiple wraps displacement rope on the basis that guarantees measuring accuracy on rope drum, increased the length of the throw of poston that will measure greatly, the measuring accuracy height, and volume is little, and is simple in structure, do not influence the intensity of hanger.
Below in conjunction with Figure of description the utility model is described in detail.
Description of drawings
Fig. 1 is the structural drawing of built-in lasting high accuracy displacement sensor.
Fig. 2 is built-in lasting high accuracy displacement sensor displacement cord circuit line chart
In the accompanying drawing: 1-piston, 2-hydraulic cylinder, 3-pressure rope wiring unit, 4-measurement wheel, 5-spring, 6-rope drum, 7-hanger, 8-displacement rope, 9-scrambler, 10-soft connection.
Embodiment
In the instructions shown in the accompanying drawing, this built-in lasting high accuracy displacement sensor, rope drum 6, spring 5, scrambler 9 are arranged, press rope wiring unit 3, measurement wheel 4, displacement rope 8, hanger 7 belows to be connected with hydraulic cylinder 2 and piston 1, one cavity is arranged on hanger 7, spring 5 is connected rope drum 6 outsides, rope drum 6 is positioned at the top, order has measurement wheel 4 and presses rope wiring unit 3 below rope drum 6, end at the axle of measurement wheel 4 is connected with scrambler 9, and displacement rope 8 is by rope drum 6, measurement wheel 4 and press rope wiring unit 3 to be connected with piston 1.
The course of work of this built-in lasting high accuracy displacement sensor: this device is installed in the hanger 7 of hydraulic jack 2 upper ends, and communicate with hydraulic cylinder 2, displacement rope 8 one ends that detect piston 1 are wrapped on the rope drum 6, and the other end is connected with piston 1, displacement rope 8 and piston 1 one body runnings.When piston 1 was descending, the displacement rope 8 that connects with piston 1 drives measurement wheels 4 and rope drum 6 is rotated in the forward, and by the rotation of rope drum 6 rope drum 6 interior springs 5 was tightened up.When piston 1 is up, spring 5 relies on its restoring force to make measurement wheel 4 and rope drum 6 do reverse rotation, tension displacement rope 8, and make displacement rope 8 since press rope wiring unit 3 and measurement wheel 4 flute profile the location with endwisely slip, realize the multiple wraps of displacement rope 8 on rope drum 6, reached the increase of measuring length.
In this process, scrambler 9 is followed measurement wheel 4 and is rotated synchronously under the drive of measurement wheel 4, the displacement that can draw piston 1 thus according to the size and scrambler 9 rotating cycles of measurement wheel 4 diameters, this displacement converts digital signal to by scrambler 9, be sent to the control instrument of hydraulic jack 2 detection systems, can demonstrate the displacement data of hydraulic cylinder piston 1 on the one hand by control instrument, on the other hand, reach robotization control and digital management by the displacement numerical information that detects to hydraulic system.
