Description

The approach switch pick-up unit of a kind of energy stable operation

Technical field

The utility model relates to a kind of approach switch pick-up unit by approach switch checkout equipment position, belongs to approach switch checkout equipment technical field.

Background technology

In rolled steel rod is produced, often need to utilize the position of approach switch checkout equipment.

Usual way is directly to weld buting iron on the mechanical position of equipment, buting iron is followed equipment moving, lay a plurality of approach switchs at the circuit of equipment operation simultaneously, when equipment and buting iron move to certain approach switch, buting iron triggers this approach switch, send signal, reach the purpose of being come the position of judgment device by the position of approach switch detection buting iron.This detection mode defective is:

1, because buting iron directly is welded on the equipment, the stable operation of equipment is had relatively high expectations, when equipment running status changes, detect distance between buting iron and the approach switch and change, it is unstable to cross detection signal far away, crosses nearly buting iron and can damage approach switch.

2, approach switch is affected by environment larger, steel mill's general environment is all more abominable, and such as high temperature, water, iron scale etc., collection volume regional temperature can reach more than 80 degree, as adopting high temperature resistant approach switch expense higher, site environment has water also can cause the interface short circuit simultaneously.

For fear of the situation of damaging approach switch owing to the unstable buting iron that causes of equipment operation, the technician improves above-mentioned detection device, wire rope and pulley gear between equipment and buting iron, have been installed additional, use the equipment haulage cable, the motion of wire rope pulling buting iron, pulley is at wire rope constraint and the steering-effecting of playing in service.This improved advantage is: at first, the fluctuation of service state of equipment is dissolved by wire rope, and wire rope is in the constraint of pulley and turn and pull back the buting iron even running, can not cause damage to approach switch.Secondly, approach switch can be moved to preferably position of environment, reduce as far as possible on-the-spot rugged surroundings to the impact of approach switch, can adopt common approach switch, and be convenient to safeguard.But this device is Shortcomings still, mainly is that on-the-spot Yin Gaowen, iron scale are more, occurs sometimes that pulley does not turn, the phenomenon of wire rope derailing, simultaneously, pulley is installed is limited in some special positions and can't uses.

The utility model content

Technical problem to be solved in the utility model provides the approach switch pick-up unit of a kind of energy stable operation, this device can adapt to the rugged surroundings at wire production scene, avoid because the unstable approach switch that causes in the equipment moving detects the uncertain of distance, and then cause the error of detection signal and the damage of electrical equipment.

The technical scheme that solves the problems of the technologies described above is:

The approach switch pick-up unit of a kind of energy stable operation, it is comprised of detection buting iron, brake cable wire rope, one end of brake cable wire rope is connected with driving arrangement, the other end is connected with the detection buting iron, in the detection course that detects buting iron guide rail is arranged, the bottom of detecting buting iron is embedded on the guide rail, detects buting iron and guide rail for being slidingly connected.

The approach switch pick-up unit of above-mentioned energy stable operation, be installed with locating ring on the detection course of described detection buting iron, locating ring is enclosed within on the brake cable wire rope, and locating ring is positioned at the place ahead with the nearest approach switch of driving arrangement, and the locating ring axis overlaps with guide rail.

The beneficial effects of the utility model are:

Hydraulic cylinder drive driving arrangement advances, backward movement, and the brake cable wire rope that is connected with driving arrangement directly drives the detection buting iron and is synchronized with the movement, and a plurality of approach switchs are by the physical location of the position judgment driving arrangement of detection buting iron.The utlity model has following advantage:

1, adopts the brake cable wire rope to substitute original wire rope, pulley blocks need not be installed, approach switch can be caused preferably position of any one environment, guarantee approach switch stable operation;

2, the brake cable wire rope is flexible tractive, is subjected to mechanical influence less, plant equipment rock the signal that can not lead to errors;

3, owing to not having pulley that wire rope is turned to and retraining, the drawbacks such as wire rope derailing and pulley fault have been avoided;

4, not affected by environment, failure rate is extremely low, reduces equipment maintenance cost, reduces the plant maintenance workload.

The utility model will be reduced to minimum degree because plant issue causes detecting the error signal fault, reduce failure rate, reduce equipment maintenance cost, save enterprise cost.

Description of drawings

Fig. 1 is structure of the present utility model and working state schematic representation;

Fig. 2 is another working state figure of the present utility model.

Mark is as follows among the figure: hydraulic cylinder 1, driving arrangement 2, brake cable wire rope 3, detection buting iron 4, approach switch 5, locating ring 6.

Embodiment

The utility model forms by detecting buting iron 4, brake cable wire rope 3, locating ring 6 and guide rail.

The utility model adopts brake cable wire rope 3 to substitute original wire rope, wire rope is turned to and retrains without pulley, has avoided the drawbacks such as wire rope derailing and pulley fault, and the oil sealing waterproof has been arranged, high lubricating effect in the brake cable wire rope.But the brake cable wire rope on the market is generally 2.5mm2, and is partially thin, therefore needs the brake cable wire rope of special use customized.

Show among the figure, for brake cable wire rope 3 can accurately be moved along detecting route, be installed with locating ring 6 in the detection course that detects buting iron 4, locating ring 6 is enclosed within on the brake cable wire rope 3, locating ring 6 is positioned at the place ahead with the nearest approach switch 5 of driving arrangement, locating ring 6 axis overlap with guide rail, and constraint brake cable wire rope 3 moves along guide rail.

In actual testing process, hydraulic cylinder 1 drive driving arrangement 2 advances, backward movement, the brake cable wire rope 3 that is connected with driving arrangement 2 directly drives detection buting iron 4 and is synchronized with the movement, and a plurality of approach switchs 5 are by the physical location of the position judgment driving arrangement 2 of detection buting iron 4.
