Abstract
The invention relates to a hydraulic starting and stopping limit device protecting device. The hydraulic starting and stopping limit device protecting device is used for controlling limit position devices starting and stopping the pendulum angle of an oil cylinder. The hydraulic starting and stopping limit device protecting device comprises a frame, an oil cylinder bearing shaft, a sensing needle, a sensing support and proximity switches. Both sides of the top of the frame are respectively provided with a support seat; the two support seats are rotatably connected with the oil cylinder through the bearing shaft; one side of the outer edge of the frame is provided with the sensing support, the sensing support is provided with two proximity switches; the end surface of the cylinder body bearing shaft, which is positioned on the side of the frame where the sensing support is mounted, is provided with the sensing needle. The hydraulic starting and stopping limit device protecting device achieves a good limit control function and meanwhile is easy to manufacture, free from influence of dust, long in service life, compact in structure, capable of effectively solving the problem of accidents caused by errors generated during the operating process of the oil cylinder and improving the safety performance of the hydraulic oil cylinder, and relatively low in cost.
Description
Technical field
The present invention relates to hydraulic hoist proterctive equipment technical field, especially a kind of hydraulic hoist extreme position protective device.
Background technology
The separately protected device of existing deep-outiet radial gate oil cylinder of hydraulic headstock gear did not also have, all only has the height limiting device adopting and one gate is set on gate, and the device of this form, although be determined by the stroke of headstock gear hydraulic cylinder, hydraulic cylinder itself realized, but on the one hand, because oil cylinder exists certain error in installation process, when oil cylinder is connected with gate lifting eye, have deviation, on the other hand, because gate is in running, produce lateral displacement sometimes, then can not control oil cylinder pendulum angle well, thus can better the open and close of regulating gate.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve in prior art in oil cylinder of hydraulic headstock gear running produce error and cause fortuitous event produced problem; improve the security performance of hydraulic jack, structure is simple and cost is lower, the hydraulic hoist extreme position protective device with good spacing controlling functions of long service life.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hydraulic hoist extreme position protective device, for controlling the extreme position device of headstock gear oil cylinder pendulum angle, comprise frame, two bearings, oil cylinder bolster, induction support, induction pointer and proximity switch, described frame top bilateral symmetry arranges two bearings, described oil cylinder bolster is rotatably supported between two bearings, described induction support is fixedly mounted on the outward flange of frame side, described induction support is arranged two proximity switches, described two proximity switches are arranged on two extreme position during cylinder efficient respectively, described induction pointer is arranged on the end face of close induction support one end of oil cylinder bolster.
A self-lubricating knuckle bearing is respectively provided with in the bearing hole of described two bearings, described self-lubricating knuckle bearing and oil cylinder bolster are rotationally connected, described self-lubricating knuckle bearing is fixed on two bearings by baffle plate, assembles a spacer between the shaft shoulder of described oil cylinder bolster and self-lubricating knuckle bearing.
The invention has the beneficial effects as follows, the pendulum angle of oil cylinder can be ensured at hydraulic hoist operation, compared to prior art, when oil cylinder is provided with error, adjustment that can be suitable, makes the operation of oil cylinder safer, the present invention simultaneously has good spacing controlling functions, its structure is simple, low cost of manufacture, long service life.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The specific embodiment of the hydraulic hoist extreme position protective device of the present invention as shown in Fig. 1 ~ 7, comprise frame 1, oil cylinder bolster 2, induction support 3 and induction pointer 4, both sides, described frame 1 top are respectively provided with a bearing 6, be rotationally connected by self-lubricating bearing 7 with oil cylinder bolster 2 between described two bearings 6, one end of self-lubricating bearing 7 arranges a baffle plate 8, for fixing self-lubricating bearing 7, a spacer 9 is assembled between the shaft shoulder of oil cylinder bolster 2 and self-lubricating bearing 7, for the protection of the wearing and tearing of oil cylinder bolster 2, be positioned at oil cylinder bolster 2 side and the induction pointer 4 that can control oil cylinder pendulum angle is set, the frame arranged outside energy Perceived control being positioned at the homonymy installing induction pointer 4 answers the proximity switch of pointer 4 pendulum angle, this proximity switch is then arranged in the holes of induction support, the extreme position of completely open and close time setting angle is set as cylinder efficient.
Operating position exactly time the form that the present invention adopts proximity switch to control oil cylinder pendulum angle can ensure cylinder efficient, compared to prior art, when oil cylinder is provided with error, adjustment that can be suitable, makes the operation of oil cylinder safer.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on manual, must determine its technical scope according to right.
