Short-distance mobile device and method for drilling rig along track

technical field

The invention relates to a heavy machinery moving device and a moving method, in particular to a device for short-distance movement of a drilling machine along a track and a method for short-distance movement along the track.

Background technique

The occurrence conditions of coal seams in my country are complex, high gas and coal and gas outburst mines account for about 1/3, and the prevention and control of coal mine gas accidents is always the top priority of safe production. The use of boreholes for gas extraction (release) is an important method of gas control and the basis for comprehensive utilization of gas (coal bed methane).

However, at present, the overall gas drainage effect of my country's coal mines is not good, and the specific performance is that the gas drainage rate is low. The lack of drilling engineering is the main reason for the low gas drainage efficiency. The main factor of hole engineering quantity. Because crawler drilling rigs have relatively high requirements for tunnels, fully hydraulic tunnel drilling rigs are currently used more commonly. Nine products of 5 types from MK-2 to MK-6 developed by the Xi'an Branch of the Coal Research Institute can adapt to the domestic coal seam conditions and have become the main products of coal mine underground drilling equipment.

MK drilling rigs are generally composed of three parts: the main engine, the pump station, and the console. Downhole relocation requires dismantling the pipeline, dismantling the drilling rig into parts, and reassembling after transporting to the place. This method is more convenient for MK-2 to MK4 drilling rigs, but for medium-deep hole and deep hole MKD-5 and MK-6 drilling rigs, the volume and quality of the whole and parts are large, and it is very difficult to move and relocate, and it consumes a lot of energy. For a long time, the labor intensity of workers is high. As the drilling speed of drilling rigs becomes faster and the relocation becomes more and more frequent, the auxiliary time used for relocation and stabilizing the drilling rig has a great impact on the production progress. And need to move two to three times a day. It increases the labor intensity of workers and reduces the efficiency of gas extraction.

Contents of the invention

The object of the present invention is to provide a new short-distance moving device for drilling rig along the track and its use method, so as to improve the movement stability and speed of the drilling rig, and reduce the labor intensity of workers at the same time.

The sliding shoe includes a support seat and a support plate for supporting the drill, and a liner is provided under the support seat to prevent sparks due to friction , the support plate is connected with a fixing mechanism for fixing the drilling rig; the traction mechanism includes the main body of the column return device, the end of the main body of the column return device is equipped with a lifting ring, and the tail has pins; the clamping rail includes a terminal that can be clamped on the track , Rotate the eccentric connecting rod connected on one side of the end, the end is provided with a bayonet for clamping the track, the bayonet is provided with a splint connected with the end, one end of the eccentric connecting rod is in contact with the splint, the splint and the end There is a recovery mechanism between the heads, and the other end of the eccentric connecting rod is connected with the traction mechanism through a shackle.

The recovery mechanism includes a screw with one end connected to the end head and a spring passing through the screw, the splint is located between the spring and the inner side of the end head, and the spring presses against the splint.

The splint is provided with a counterbore, and the ends of the spring and the screw are located in the counterbore.

The two ends of the support seat of the slide shoe are skid-shaped.

The splint is limited by a pin shaft connected to the lowermost end inside the bayonet socket of the end.

The tail of the eccentric connecting rod is an eccentric circle.

One end of the terminal is provided with a rotary shaft, and the eccentric connecting rod is connected in rotation with the rotary shaft.

The pad is copper pad or high-strength plastic or high-strength nylon.

The method for short-distance movement of the drilling rig along the track using the above-mentioned short-distance moving device for the drilling rig comprises the following steps:

The first step is to put the sliding boots on the track and the sleepers. The pads are welded at the contact between the sliding boots and the track. The drilling machine is installed on the sliding boots. There are fixing holes on the inner side of the supporting plate of the sliding boots. The fixing seat of the fixing mechanism Installed on the support plate, when using the fixed sliding shoe bolts, different round holes should be selected according to the position of the drilling rig, and at the same time adjust the advancing amount of the fixing drilling rig bolts in the fixing seat to fix the drilling rig;

The second step is to place the clamping rail in front of the drilling rig according to the primary traction amount of the traction mechanism. The end of the clamping rail is placed on the track. The front end is connected to the steel wire rope covering the base of the drilling rig through the lifting ring;

The third step is to shake the traction mechanism by hand to provide power for the movement of the drilling rig and the slide shoe. At this time, the traction mechanism drives the eccentric connecting rod of the clip rail to push the splint, so that the clamping track provides a fulcrum for the movement of the drilling rig; as the traction mechanism is shaken by hand, The drilling rig moves forward gradually, and when it reaches the required position, the traction mechanism stops working;

In the fourth step, if it is necessary to move the drilling rig further forward, the clamping rail needs to be removed from the track; the method is: first loosen the wire rope wound on the gear mechanism, and then apply an external force on the front end of the eccentric connecting rod along the moving direction of the drilling rig, Make the eccentric connecting rod no longer push the splint, and at this time, the splint returns to the initial position under the push of the return mechanism; the second and third steps can be repeated to make the drill reach the expected position; if the third step has made the drill reach the predetermined position, cancel the fourth step;

The fifth step, after completing the required amount of drilling rig forward movement, remove the clamping rail, and place the clamping rail in a suitable position again so as to move the drilling rig next time.

When the eccentric connecting rod is not stressed, the recovery mechanism of the clamping rail can return the splint to the initial position.

The invention discloses a short-distance moving device and method for a drilling machine along a track. The device comprises a sliding shoe supporting the drilling machine, a fixing mechanism for fixing the drilling machine, a clamping rail providing a fulcrum for moving the drilling machine, and a traction mechanism providing power. The slide shoe includes a support seat, a support plate, a support rib and a liner. The pads rub against the track to prevent sparks as the shoe moves on the track and are replaceable when worn. The contact area between the drilling rig and the sleepers is increased by the sliding boots to prevent the drilling rig from deflecting when moving, and the two ends of the sliding boots are skid-shaped to prevent the sliding boots from damaging the sleepers when moving on the sleepers. The clamping rail pushes the splint to clamp the track through the eccentric connecting rod, thereby providing a fulcrum for the movement of the drilling rig, and the clamping rail is withdrawn from the track to facilitate the movement of the drilling rig. In order to make the clamping rail retreat smoothly from the track, a return mechanism is provided in the end and the splint: when the eccentric link is stressed, the spring of the return mechanism is in a compressed state, and when the eccentric link is not stressed, the spring lifts the splint. The clip rail just can be taken off from the track.

The tail of the eccentric connecting rod is an eccentric circle, which can not only ensure the forward movement of the splint but also realize eccentric self-locking.

Among them, the rotary shaft of the clip rail must be able to withstand the shear force given by the eccentric connecting rod. When the eccentric connecting rod is not stressed, the clip rail recovery mechanism can return the splint to the initial position. The splint will not wear out too quickly in contact with the track, and it is easy to replace as a wearing part.

The traction mechanism pulls the drilling rig and the slide shoe through the wire rope, and the forward movement of the drilling rig can be realized by shaking the handle of the traction mechanism. The end of the traction mechanism is equipped with suspension rings and pins at the tail, and the other parts are basically the same in structure as the existing column return device, such as containing handles and gear mechanisms. The clamp rail and traction mechanism are light in weight, easy to move and easy to carry.

By using the device and method for short-distance movement of the drilling rig along the track of the present invention, the moving speed of the drainage drilling rig along the track can be greatly improved, while the labor intensity of workers can be reduced, and the efficiency of gas drilling and extraction can be improved. The invention is reasonable in design, simple in structure, safe and reliable, greatly improves the moving speed of the drilling rig, reduces the labor intensity of workers, improves work efficiency, and is worthy of popularization and application in coal mining enterprises.
