Description

A device for automatically moving the head of a loader

technical field

The invention belongs to the technical field of coal mining machinery, and particularly relates to a device for automatically moving the head of a loader.

Background technique

The full name of the loader is the scraper loader for troughs, also known as the scraper conveyor. Conveying equipment that plays an important role in connecting the three machines. The loader consists of three parts: the nose, the middle and the tail. Its working principle is to use the open chute as a bearing part for coal, gangue or materials, etc., and fix the scraper on the chain (compose a scraper chain) , as the traction member. When the machine head transmission part is started, the sprocket on the machine head shaft is driven to rotate, so that the scraper chain runs circularly and drives the material to move along the chute until it is unloaded at the machine head, and the scraper chain bypasses the sprocket for a stepless closed cycle operation. , to complete the material delivery. In the current coal mining face, the function of the scraper conveyor is not only to transport coal and materials, but also the running track of the shearer, so it has become an indispensable main equipment in the modern coal mining process. The scraper conveyor can keep running continuously, and the production can be carried out normally, otherwise the entire coal mining face will be in a shutdown state, which will interrupt the entire production.

When working, one end is connected to the conveyor on the working surface, and the other end is connected to the tail of the belt conveyor. The loader is adjusted as a whole with the advancing step of the working face conveyor. The coal is transported out by the working face conveyor, and then transferred to the retractable belt conveyor after being raised from the tunnel floor by the bridge loader.

However, when the head of the loader is overlapped with the tail of the conveyor, it is necessary to consider the support and movement of the head of the loader. The loader needs to manually shrink the belt and extend the scraper to operate, which is labor-intensive, time-consuming, and runs continuously. Poor performance, resulting in low work efficiency; in addition, the car will be frequently choked and delayed, which has a large potential safety hazard, wastes a lot of materials, and requires a large amount of maintenance.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a device for automatically pushing the head of the loader to move the loader into place conveniently and quickly.

A device for automatically pushing the head of a loader, comprising a support seat and a rail, characterized in that the support seat includes a beam, the bottom of the beam is provided with a bottom-lifting cylinder, and both ends of the beam are bent downwards, Both ends of the beam are provided with connectors, the connectors are all "Π" shaped, the middle of the connector is connected to the end of the beam, both ends of the connector are connected to support legs, the The support leg is provided with a support leg cylinder, the two sides of the bottom of the support leg are provided with rollers matching the track, the track is provided with a push cylinder, and the two ends of the push cylinder are respectively hinged with the track and the support leg.

Further, there are four groups of the support legs, convex side plates are arranged on both sides of the support legs, the side plates are connected by two groups of connecting plates, the top of the support legs is a cover plate, and the cover The bottom of the plate is fixedly connected with the cylinder of the supporting leg, and the side plates are provided with a plurality of groups of reinforcing ribs.

Further, the bottom of the bottom-lifting cylinder is provided with a bearing block, and the bearing block is square.

The beneficial effects of the present invention are:

After the device is used, the lap joint of the loader and the rear conveyor is realized, and the maintenance cost of using the turning belt conveyor is saved.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

A device for automatically pushing the head of a loader, comprising a support seat and a rail 2, characterized in that the support seat includes a beam 1, a bottom-lifting cylinder 3 is provided at the bottom of the beam 1, and both ends of the beam 1 are Bend down, both ends of the beam 1 are provided with connectors 4, the connectors 4 are all "Π" shape, the middle of the connector 4 is connected with the end of the beam 1, the connector 4 is Both ends of 4 are connected to support legs 5, and the support legs 5 are provided with support leg cylinders 6, and both sides of the bottom of the support legs 5 are provided with rollers 7 that match the track 2, and the track 2 is provided with a pusher Cylinder 8, two ends of the push cylinder 8 are hinged with the rail 2 and the support leg 5 respectively.

The device for automatically pushing the head of a loader according to claim 1, wherein the support legs 5 are in four groups, and two sides of the support legs 5 are provided with convex side plates 51. The side plates 51 They are connected by two sets of connecting plates 52 . The top of the support leg 51 is a cover plate 53 , and the bottom of the cover plate 53 is fixedly connected to the support leg cylinder 6 . The side plate 51 is provided with a plurality of groups of reinforcing ribs 54 .

A device for automatically moving the head of a loader according to claim 1, wherein the bottom of the bottom-lifting cylinder 3 is provided with a bearing block 31, and the bearing block 31 is square.

When the machine head is pushed, the rollers 7 at the bottom of the support legs are attached to the track 2, slide on the track, and the push cylinder 8 is extended; Start, retract the support leg cylinder 6 to separate the support leg 5 from the rail 2, and then retract the push cylinder 8. At this time, the runway moves forward under the action of the push cylinder 8, and moves alternately in the above-mentioned manner to realize the movement of the loader. step.
