Abstract
The utility model relates to a jack stroke position detection sensor, which is composed of a U-shaped clamping block, a draw rod, two permanent magnetic supporting seats, a clamping plate, an outer cylinder, micro switches, etc. The micros switches are fixed between two clamping plates with strip-shaped long slots and are arranged in an inner cavity of the outer cylinder. The clamping plates are connected with the outer cylinder through an adjusting block. Rolling wheels of the micro switches pass through a waist hole on the outer cylinder and are extended out of the outer cylinder. The external cylinder is fixed to an oil cylinder of a jack by the permanent magnetic supporting seats which are arranged on both ends of the outer cylinder. A slide sleeve is sheathed on the outer cylinder and is connected with one end of the draw rod and can be freely slid on the outer cylinder. The other end of the draw rod is connected with the U-shaped clamping block which is clamped on a piston head of a main jack. A pin of each micro switch is respectively connected with each wire connecting column of a wire connecting terminal by lead wires.
Description
The utility model relates to a kind of sensor that detects the hydraulic jack travel position.
Micro-switch or shape journey switch that tradition is used to detect jack are to adopt exposed dispersion to install, and neither attractive in appearancely can not prevent dust effectively again, and very easily by accident collision, form the false judgment of control system, cause the lifting potential safety hazard; Its setting accuracy also is difficult for guaranteeing that check point also is difficult for adjusting; Secondly, micro-switch disperses to install, disperses wiring very easily to make a mistake, and has reduced reliability; In addition, the mounting hole of processing on oil cylinder, mounting plane can reduce the intensity of oil cylinder.
The purpose of this utility model be to provide a kind of simple in structure, reliability is high, jack travel position detecting sensor easy to adjust is installed.
For reaching above-mentioned purpose, jack travel position detecting sensor of the present utility model is by the U-shaped fixture block, pull bar, the permanent magnetism bearing, clamping plate, urceolus, a plurality of micro-switchs, slide cover, adjust piece, lead and connection terminal form a whole, each micro-switch is fixed by bolts in the middle of two clamping plate that have a bar shaped elongated slot, place the inner chamber of urceolus, clamping plate link to each other with urceolus by adjusting piece, have corresponding strip shape waist hole on the urceolus, each micro-switch roller passes this hole and stretches out outside the tube, the permanent magnetism bearing that is positioned at the urceolus two ends is fixed on urceolus on the oil cylinder of main jack by the magnetic mode of closing, the condom that slides that the aperture is slightly larger than the urceolus external diameter links to each other with pull bar one end on urceolus, and can on urceolus, be free to slide, the pull bar other end links to each other with the U-shaped fixture block by screw, the U-shaped fixture block is stuck in the piston crown of main jack, and lead links to each other each micro-switch pin respectively with each binding post of connection terminal.
Working process is as follows:
When piston drives the operation of U-shaped fixture block, slide the roller that cover is depressed the micro-switch that slides the cover position successively, control system detects the signal of relevant position thus, reaches the purpose of detection.Adjust piece and can adjust the radial position of micro-switch in urceolus by screw, assurance is slided cover and is contacted with the effective of micro-switch roller, bar shaped elongated slot on urceolus and the clamping plate can be adjusted the axial dimension of micro-switch with respect to urceolus, reaches the purpose of adjusting the check point spacing.The jack travel position detecting sensor of the utility model not only can detect the signal of jack position stroke on the diverse location, also is applicable to the lifting jack that detects different strokes.
The jack travel position detecting sensor of the utility model concentrates on a plurality of micro-switchs in the osed top tube and installs, not only attractive in appearance, dustproof, and prevented the misoperation that the accident collision because of the external world produces to a great extent, improved the reliability of device widely, and installation dimension precision height; The permanent magnetism bearing that adopts permanent magnet to make links to each other with oil cylinder, installs, adjusts very convenient, and because of needn't be at oil cylinder surface working mounting hole, assurance oil cylinder intensity reduce.
Below, the architectural feature to the jack travel position detecting sensor of the utility model is described further in conjunction with the accompanying drawings and embodiments.
