Abstract
The utility model relates to a length and stroke position combined sensor, which comprises a bracket and an oil cylinder working cylinder. The length and stroke position combined sensor is characterized in that a full-extension limit switch and a nearly-full-extension limit switch are installed at the front part of the bracket, the nearly-full-extension limit switch is positioned on the inner side of the full-extension limit switch, a nearly-full-retraction limit switch and a full-retraction limit switch are installed at the rear part of the bracket, the nearly-full-retraction limit switch is positioned on the inner side of the full-retraction limit switch, a guy wire sensor is installed at the front top end of the bracket, a guy hook positioning plate is fixed at the top end of the oil cylinder working cylinder, a guy wire is led out by the guy wire sensor to be connected with the guy hook positioning plate, and an arc limit stop dog is installed at the top part of the oil cylinder working cylinder and corresponds to the full-extension limit switch, the nearly-full-extension limit switch, the nearly-full-retraction limit switch and the full-extension limit switch during the full stroke of the oil cylinder working cylinder. The length and stroke position combined sensor provided by the utility model has the advantages of simple structure, simplicity of manufacture, good reliability, convenience in adjustment and maintenance, and high accuracy in stroke length measurement, and can meet special requirements for building displacement; and accurate positioning can be controlled through a computer during the displacement and be displayed in digital straightforwardly.
Description
Technical field
The utility model relates to a kind of stroke sensor, particularly a kind of multiple spot position transducer of setting in length of stroke and the process that detects.
Background technology
In the modern building fabric installation work, use the load-bearing of cluster steel strand wires, computer control to organize the synchronous lift technique of hydraulic pressure punching oil cylinder more and be applied.In promoting operation, former use detects the sensor of hydraulic pressure punching oil cylinder working cylinder travel position, only need to detect the position of all stretching out with whole withdrawals, can realize stretching entirely and draw pine ground tackle up and down when full reduced by working cylinder, finish load transfer between the ground tackle up and down, thereby synchronous lifting operation is carried out continuously.
As the former installing and locating point of heavy construction structure, because of special circumstances must drop to new installing and locating point from former installing and locating point.So just building structure must be descended synchronously, band carried lifting when promptly crude oil cylinder working cylinder stretched out, unloaded withdrawal, and existing operating mode is that the working cylinder band carries withdrawal decline, zero load is stretched out.For still needing to draw the pine purpose of ground tackle realization load transfer up and down by working cylinder, the working cylinder band carries the withdrawal foot that can not contract, zero load is stretched out and can not be stretched foot, must leave the segment distance, thus must increase the working cylinder stroke on the sensor stretch two anchor points of (not stretching foot) closely full reduced (foot does not contract) closely entirely.Original sensor can't satisfy the requirement of realization, and all there are defective in the element quality of former stroke sensor and design in addition, the element failure rate height, and maintenance is inconvenient, not energy measurement oil cylinder working cylinder stroke work attitude actual numerical value.
Summary of the invention
The utility model purpose is to solve the existing existing problem of stroke sensing, and a kind of simple in structure, combination sensor that expanded function can satisfy the buildings displacement request is provided.The utility model design length and travel position combination sensor, comprise support, the oil cylinder working cylinder, it is characterized in that: be equipped with one in the front portion of support and stretch limit switch and one entirely and stretch limit switch closely entirely, stretching limit switch closely entirely is positioned at and stretches the limit switch inboard entirely, a nearly full reduced limit switch and a full reduced limit switch are installed at the rear portion of support, nearly full reduced limit switch is positioned at full reduced limit switch inboard, the backguy sensor is installed in the preceding top of support, the guy hook location-plate is fixed on the top of oil cylinder working cylinder, backguy is drawn by the backguy sensor and is connected the guy hook location-plate, at oil cylinder working cylinder top the spacing collision block of arc is installed, the spacing collision block of arc in the total travel of oil cylinder working cylinder with stretch limit switch entirely, stretch limit switch and nearly full reduced limit switch closely entirely, full reduced limit switch correspondence is characterized in that: stretch limit switch entirely, stretch limit switch and nearly full reduced limit switch closely entirely, full reduced limit switch is roller plunger type microswitch.The utility model has the advantages that simple in structure, make simple and easy, good reliability, easy to maintenance, the length of stroke measuring accuracy height of adjustment, can satisfy the specific (special) requirements of buildings displacement and can be when displacement by accurately location and intuitively numeral demonstration of computer control.
Description of drawings
Accompanying drawing is a section of structure of the present utility model.
Embodiment
Comprise support 1 among the figure, oil cylinder working cylinder 10, it is characterized in that: be equipped with one in the front portion of support and stretch limit switch 5 and one entirely and stretch limit switch 4 closely entirely, stretching limit switch closely entirely is positioned at and stretches the limit switch inboard entirely, a nearly full reduced limit switch 3 and a full reduced limit switch 2 are installed at the rear portion of support, nearly full reduced limit switch is positioned at full reduced limit switch inboard, backguy sensor 6 is installed in the preceding top of support, guy hook location-plate 8 is fixed on the top of oil cylinder working cylinder, backguy 7 is drawn by the backguy sensor and is connected the guy hook location-plate, the spacing collision block 9 of arc is installed at oil cylinder working cylinder top, the spacing collision block of arc in the total travel of oil cylinder working cylinder with stretch limit switch entirely, stretch limit switch and nearly full reduced limit switch closely entirely, full reduced limit switch correspondence is characterized in that: stretch limit switch entirely, stretch limit switch and nearly full reduced limit switch closely entirely, full reduced limit switch is roller plunger type microswitch.
During making, on support according to oil cylinder working cylinder length of stroke bore full reduced when stretching entirely two pilot holes, again apart from full reduced stretch entirely bore between the pilot hole closely full reduced, stretch pilot hole closely entirely.4 roller plunger type microswitches are installed in 4 holes of support, support 1 is installed on the support of hydraulic jack, the spacing collision block of arc is installed on oil cylinder working cylinder top, with the correspondence position of oil cylinder working cylinder in full reduced position be full reduced limit switch, correspondence position is for stretching limit switch full when stretching out entirely with the oil cylinder working cylinder, on full reduced limit switch top is nearly full reduced limit switch, stretching the limit switch bottom entirely for stretching limit switch closely entirely, when the oil cylinder working cylinder stretched out, the stroke limit collision block can collide 4 limit switches successively and make its action output signal.
The backguy sensor is positioned on the support, and the guy hook location-plate is fixed on oil cylinder working cylinder top, and the oil cylinder working cylinder stretches out or during indentation, the backguy synchronization telescope of backguy sensor, output services cylinder length of stroke signal
This practical length and travel position combination sensor can satisfy implements heavy construction framework thing precise displacement and the required accuracy requirement of special operation condition displacement when computer control.
