Abstract
The utility model relates to a device for determining range and opening of arch gate and protecting deflection. The technical problem to solve of the utility model is to provide a device for determining range and opening of arch gate and protecting deflection which is simple and reasonable in construction, stable in performance and fine in repetitive definition and effectively avoids axis downward deflection and being disturbed for wind blowing, water flotage and other environmental conditions when a hydraulic cylinder detects a big range so as to obtain accurate detection signal. The technical proposal for the problem is that the device for determining range and opening of arch gate and protecting deflection is provided with a detected movable part which is characterized in that the detected movable part is connected with a sleeve pulled rod formed by an inner rod and an outer rod, the inner rod and the outer rod can flex relatively via a fixed bracket and the other end of the inner rod is pivoted with the measured movable part. The utility model can be applied to the range detection of QHLY series hydraulic headstock gear in water conservancy and water and electricity works and the opening detection of arch gate and can prevent axis down deflection due to the self-weight of the hydraulic cylinder when being tilted, etc.
Description
Technical field
The utility model relates to a kind of stroke and arc gate opening detects and the anti-device of scratching.Be applicable to the stroke detection of Hydraulic and Hydro-Power Engineering QHLY Series Hydraulic headstock gear, Segment gate aperture detected, prevented that hydraulic cylinder from causing because of deadweight when tilting axis downwarp etc.
Background technology
QHLY Series Hydraulic headstock gear is to be widely used in the Hydraulic and Hydro-Power Engineering and the great a kind of type of quantity, be the double-cylinder hydraulic headstock gear, the most employing of the hydraulic cylinder travel detection wire rope transmission external opening self-detective instrument 4 of home equipment ', as shown in Figure 3, this aperture instrument adopts mechanical code-disc or photoelectric code disk as sensor, by wire rope 3 ' and constant force spring or weight driven rotary, delivery stroke detection signal continuously.QHLY Series Hydraulic headstock gear hydraulic cylinder 1 ' for being in tilted layout, when gate 6 ' complete shut-down, piston rod 2 ' whole process is overhanging, and the hydraulic cylinder deadweight can cause the hydraulic cylinder axis downwarp, the at present normal anti-measure of adopting of scratching be gate pier abutment wall corresponding positions install a block 5 '.This scheme exists weak point to be: 1), wire rope transmission external opening self-detective instrument is because wire rope is thinner, very easily be subjected to the interference of ambient conditions such as wind and influence the correctness of detection signal, when stroke very big and during as the twin-tub synchronous detection signal more very; 2), when adopting establish block as shown in Figure 3 anti-to scratch measure, the shortcoming of the difficulty of regulating is arranged, and when floater is trapped in block above the time, can cause the hydraulic cylinder axis arch to be out of shape.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of stroke and arc gate opening to detect and the anti-device of scratching, this apparatus structure advantages of simple, stable performance, repeatable accuracy are splendid, when carrying out big stroke detection, hydraulic cylinder can effectively prevent the axis downwarp, be not subjected to ambient conditions, as the interference of wind, floater, detection signal is correct.
The technical scheme that the utility model adopted is: stroke and arc gate opening detect and the anti-device of scratching, has tested movable part, its design feature above tested movable part by fixed bearing connect one by two sections interior bars that can stretch relatively with outside the telescopic tension member formed of bar, the other end of interior bar is connected with tested movable part in hinged way.
A cover magnetostriction linear transducer is equipped with in the inside of described telescopic tension member.
Described fixed bearing is a hydraulic cylinder supporting hinge embedded part.It also can be gate fixed hinged seat basis.
Described tested movable part is a hydraulic cylinder, and the other end of interior bar is connected with hydraulic cylinder in hinged way.Described tested movable part also can be Segment gate, and the other end of interior bar is connected with the arc support arm of door in hinged way.
The beneficial effects of the utility model are: can effectively improve equipment control and the reliability of controlling far away automatically, concerning the synchronous closed-loop control of twin-tub, develop a kind of stable performance, the detection sensing device that repeatable accuracy is splendid; Using need not increase miscellaneous part behind this device and can solve the anti-problem of scratching of hydraulic cylinder axis.This apparatus structure advantages of simple, be not subjected to environmental influence, detection signal correct.
