Description

Technical Field

[0001] The invention relates to a device and a method for laying a fully-mechanized mining track in a coal mine, and belongs to the field of coal mine equipment. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip off the surface soil layer to mine coal. This is an open-pit coal mine.

[0003] At present, most coal mine fully mechanized mining tracks are transported to the vicinity of the track laying location by traction vehicles, and then manually carried to the laying location. This method is not only unstable but also labor-intensive.

[0004] For example: The Chinese invention patent / utility model patent (application number: CN202120778848.2) discloses a "tractor-assisted track laying device for coal mining". Its specification discloses: The track laying equipment currently used in coal mining, when in use, most of the track laying is to transport the track beams to the track laying site by a tractor. The track beams are manually lifted to the placement site, or the placement ground has bumps of different heights that make it impossible to place the track beams stably on the ground. For this reason, technicians in this field have proposed a tractor-assisted track laying device for coal mining; the above patent can prove the defects of the existing technology.

[0005] Therefore, we have made improvements to this and proposed a coal mine fully mechanized mining track laying device and method. Summary of the Invention

By setting the laying mechanism, when the base moves under the drive mechanism, the rails in the holding rack can fall at the preset positions of the rails in turn, and are not prone to offset under the action of the limiting mechanism.

[0012] In which, the laying mechanism also includes a rectangular hole opened at the bottom of one side of the holding rack, the bottom of the front and rear sides of the holding rack are both provided with grooves connected to the rectangular hole, and the top and bottom of one side of the groove are both provided with a slide groove, and a first connecting wheel and a second connecting wheel are provided inside the rectangular hole, and the middle parts of the first connecting wheel and the second connecting wheel are respectively connected to the adjacent slide grooves through a circular shaft, and the circumferential side of the third connecting wheel is provided with a first arc groove and a second arc groove adapted to the first connecting wheel and the second connecting wheel. By arranging the second connecting wheel and the first connecting wheel, the third connecting wheel cooperates with the first arc groove and the second arc groove during rotation, so that the first connecting wheel and the second connecting wheel can move, and when the second connecting wheel moves to both sides, the track placed between the two second connecting wheels can fall from the inside of the holding rack to the ground, and at this time the two first connecting wheels move closer to the middle, so that the other tracks in the holding rack cannot fall, thereby completing the process of the tracks falling in sequence.

[0013] Wherein, both ends of the circular shaft on the first connecting wheel are fixedly connected with a first spring, one end of the first spring is fixedly connected with a connecting block, and one end of the connecting block is fixedly connected to one side of the groove.

By setting a limiting mechanism, the track can be restricted by the limiting plates when it falls between the two limiting plates, so that the track is not easily laid crooked. In the process of the track falling, the track line contacts the auxiliary wheel in the vertical direction, so that the auxiliary wheel moves and pulls the third spring to play a buffering role on the track. When the auxiliary wheel rotates to the horizontal direction, the rotating auxiliary wheel drives the track to move to the bottom of the holding rack, so that the third connecting wheel rotates to move the track to the inside of the holding rack.

[0017] Among them, the interior of the limiting plate is connected to a worm through a bearing, and a third motor for driving the worm to rotate is fixedly installed on one side of the limiting plate.

[0018] The method for laying a fully-mechanized mining track device in a coal mine comprises the following steps:

[0019] Step 1, laying: put multiple tracks into two holding racks respectively, control the first motor to work, and under the drive of the first sprocket, the second sprocket and the chain, the round wheel rotates accordingly. When the base moves to the designated laying position, control the second motor to drive the third connecting wheel to rotate. When the second arc groove on the third connecting wheel rotates to the second connecting wheel, the second connecting wheel moves to the inside of the second arc groove under the action of the second spring. When the second connecting wheel moves to both sides, the track placed between the two second connecting wheels can fall from the inside of the holding rack to the ground. At this time, the two first connecting wheels move closer to the middle, so that the other tracks in the holding rack can be laid on the ground. The track cannot fall. When the third connecting wheel continues to rotate, the second arc-shaped groove separates from the second connecting wheel, the first arc-shaped groove rotates to the first connecting wheel, the first connecting wheel enters the first arc-shaped groove, and the two first connecting wheels separate from each other. At this time, the two second connecting wheels move closer to the middle under the pressure of the third connecting wheel. The track falls from the middle of the two first connecting wheels and is placed on the two second connecting wheels. When it is necessary to continue laying, the third connecting wheel is rotated in the opposite direction to separate the first connecting wheel from the first arc-shaped groove, and the second connecting wheel enters the second arc-shaped groove. By controlling the intermittent forward and reverse rotation of the third connecting wheel, multiple tracks are controlled to fall one by one.

[0020] Step 2: Recycling: Pull the movable plate to separate the insert block from the slot, adjust the position of the third connecting wheel so that the third connecting wheel is placed at the bottom of the base and enters between the two limit plates, loosen the movable plate to insert the insert block into the slot. During the adjustment process, the connecting shaft can rotate accordingly, and then adjust the position of the rotating block, adjust the state of the second spring so that the second connecting wheel can be pulled toward the inside of the holding rack by the second spring, pull the two fourth connecting rods toward the middle to separate the fourth connecting rods from the first slot, rotate the auxiliary wheel to make the auxiliary wheel horizontal, loosen the fourth connecting rod, insert one end of the two fourth connecting rods into the third slot and the second slot, insert the square rod into the square slot, control the third motor to drive the worm gear and the auxiliary wheel to rotate, so that the track between the two limit plates moves under the action of the auxiliary wheel. When the track reaches the bottom of the holding rack, during the movement, the track contacts the third connecting wheel and drives the third connecting wheel and the second connecting rod to fold, and the track smoothly enters the bottom of the holding rack. Under the action of the coil spring, the two third connecting wheels contact the two ends of the track to control the rotation of the third connecting wheel. Under the action of static friction, the two third connecting wheels drive the track to move upward. During the movement, the track pushes the two third connecting wheels to move to both sides, and the second connecting rod gradually folds. When the track is above the two third connecting wheels and enters the interior of the holding rack, the second connecting rod gradually returns to its original shape under the action of the coil spring. The track enters the interior of the holding rack, pushes the two second connecting wheels to stretch the second spring. As the track continues to enter, the track accumulates inside the holding rack and eventually slides down into the frame under the guide of the guide plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The method for laying a fully-mechanized mining track device in a coal mine comprises the following steps:

[0053] Step 1, laying: put multiple tracks into the two holding racks 202 respectively, control the first motor 301 to work, and under the transmission of the first sprocket 302, the second sprocket 304 and the chain 305, the round wheel 303 rotates accordingly. When the base 1 moves to the designated laying position, control the second motor 415 to drive the third connecting wheel 416 to rotate. When the second arc groove 418 on the third connecting wheel 416 rotates to the second connecting wheel 405, the second connecting wheel 405 moves to the inside of the second arc groove 418 under the action of the second spring 408.

When it is necessary to continue laying, the third connecting wheel 416 is rotated in the opposite direction to separate the first connecting wheel 404 from the first arc groove 417, and the second connecting wheel 405 enters the second arc groove 418. By controlling the intermittent forward and reverse rotation of the third connecting wheel 416, multiple tracks are controlled to fall one by one;
