Abstract

The utility model relates to a tractor steel wire rope protecting device. The technical scheme is as follows: a piece of angle iron is horizontally fixed on the gear speed reducer of a tractor and positioned above two steel wire rope pulleys, a vertical plate is fixed under the angle iron and is close to the gear speed reducer but out of touch with the gear speed reducer, a proximity switch is fixed on the vertical plate, two horizontal bolts on the angle iron passes an unthreaded hole, flat iron is hoisted at the lower part of the angle iron through a bolt, and a compressing spring is mounted on the bolt in a penetrating manner and positioned between the flat iron and the angle iron; the proximity switch is added to control a loop on the basis of the conventional controlling loop of the tractor, the coils of a relay KA is in series connection in the loop controlled by the proximity switch, and the normally-closed contacts of the relay KA is in series connection in the conventional controlling loop of the tractor; when the steel wire rope bounces, the flat iron is sprung by the steel wire rope to move upwards, the flat iron triggers the proximity switch, the coils of the relay KA are powered on, the contacts of the relay KA are normally closed, and the tractor stops.

Description

Car pusher protecting device for wire rope

Technical field

The utility model relates to a kind of car pusher, especially a kind of car pusher protecting device for wire rope.

Background technique

The car pusher wire rope of coal washery is often beated at rope sheave place, very easily causes and squeezes rope, disconnected rope phenomenon, and security incident occurs, change a wire rope and be worth approximately 30,000 yuan, not only consuming time but also effort had increased maintenance man's workload, had also caused the consumption of material, and had had a strong impact on car loading operation.Therefore, designing a kind of car pusher protecting device for wire rope, is the current technical issues that need to address.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of car pusher protecting device for wire rope.

The technical scheme in the invention for solving the technical problem is:

Car pusher protecting device for wire rope, on the gear reduction unit body of car pusher, be laterally fixed with angle bar, angle bar is above two wire rope pulleys, below angle bar, be fixed with riser, riser is near gear reduction unit body but do not contact with gear reduction unit body, on riser, be fixed with approach switch, on angle bar, there are two cross bolts to pass through unthreaded hole, bottom at angle bar is lifted with band iron by bolt, on bolt, be coated with Compress Spring, Compress Spring is between band iron and angle bar, on the original control loop of car pusher basis, increase an approach switch control loop, the coil of SRE KA in approach switch control loop, SRE KA normally-closed contact in former car pusher control loop, in the time that wire rope is beated, on wire rope springing band iron, move, band iron triggers approach switch, the coil of the coil of relay K A obtains electric, relay K A normally-closed contact, car pusher stops.

As a kind of preferred version of the present utility model, on band iron, be welded with approach switch triggering block.

As a kind of preferred version of the present utility model, the gear reduction unit of described car pusher is Double shaft-extension speed reducer, be provided with car pusher protecting device for wire rope in the left and right sides of the gear reduction unit body of car pusher, described wire rope pulley divide left wire rope pulley and right wire rope pulley (, described approach switch divides left approach switch and right approach switch, left approach switch and right approach switch are relation in parallel, when wire rope on left wire rope pulley is beated, left approach switch triggers, when wire rope on right wire rope pulley is beated, right approach switch triggers, left approach switch or right approach switch trigger, the coil of the coil of relay K A all electric, relay K A normally-closed contact, car pusher stops.

As a kind of preferred version of the present utility model, described relay K A is 24v relay.

Compared with prior art, the utility model, after car pusher is installed and used, has all disconnected Electric Machine Control while there is wire rope rope skipping phenomenon timely and effectively, has played the effect of protection wire rope, has obtained good effect.The utility model, after car pusher is installed and used, not only avoids the security incident of resolving rope to occur, and has reduced maintenance man's maintenance, and has relatively saved materials consumption.
