Description

Technical Field

[0001] The utility model relates to the technical field of rail rerailing tools, in particular to an automatic rail rerailing device for mining. Background Art

[0002] The main functions of coal mine cars and tracks are to transport coal, ore and other bulk materials, as well as to transport personnel and dangerous goods in mines. Coal mine cars are narrow-gauge railway transport vehicles used to transport bulk materials such as coal, ore and waste rock in mines. They usually require locomotives or winches to be towed to adapt to the narrow conditions of underground tunnels. They have compact dimensions. In underground rail transportation in coal mines, due to factors such as tunnel floor deformation, substandard track quality and improper operation of personnel, mine car derailment accidents occur from time to time. In the past, cranes or track lifters were usually used to deal with mine car derailment. Not only was the rerailing efficiency low and the track was severely damaged, but the safety was poor and it was easy for mine car rollover accidents to occur. When using a rerailer to rerail, a large impact force is easily generated, which will affect the service life of the rerailer. In addition, the track clamps are greatly worn and need to be cut off when replaced and then re-welded and fixed for use, which is more cumbersome. Utility Model Content

The rerailer effectively solves the disadvantages of manual rerailing of mine cars, such as long time consumption, low efficiency, insufficient safety protection, and easy damage to the track, and reduces the labor intensity of employees to a certain extent, improves transportation efficiency, and provides a strong guarantee for safe production in mines.

[0004] In a first aspect of the present disclosure, an automatic rerailer for mining is provided, specifically comprising: a rerailer body; the rerailer body is an inclined right-angled triangle structure, a guide ridge is welded on the outer side of the rerailer body, and the inner side of the rerailer body is connected to the rail clamp via a connecting plate; a force-bearing structure; the force-bearing structure is installed at the bottom of the rerailer body, the force-bearing structure is made of a harder composite rubber material, three force-bearing grooves are opened on the side of the force-bearing structure, the side of the force-bearing groove is an arc-shaped structure, and the interior of the force-bearing groove is a V-shaped structure.

[0005] In at least some embodiments, a rerailing support plate is welded and fixed to the bottom of the rerailing device body, the rerailing support plate is arranged at an angle, the rear of the rerailing support plate is in contact with the force-bearing structure, and two connecting head assemblies are welded and fixed to the bottom of the rerailing support plate, and the upper and lower sides of the connecting head assembly of the T-shaped structure are inclined structures; a connecting plate of a rectangular structure is welded and fixed to the inner side of the rerailing device body, and the connecting plate is provided with three connecting holes, and the track clamp is a U-shaped structure and is erected above the track; a side groove is provided on the side of the track clamp, and three connecting bolts are fixed inside the side groove, and the connecting bolts are inserted into the connecting holes of the connecting plate.

[0006] In at least some embodiments, the front end of the force-bearing structure is an inclined structure, and two connecting grooves are provided at the front end of the force-bearing structure, and a connecting head assembly is inserted into the inside of the connecting groove; the rear of the force-bearing structure is bonded and fixed to the bonding plate structure, and the inner side of the bonding plate structure is provided with evenly arranged anti-slip grooves, the anti-slip grooves of the wedge-shaped structure and the bonding plate structure are in contact with the sleepers, and a U-shaped top plate structure is welded and fixed to the top of the bonding plate structure, and the top plate structure is in contact with the top of the sleeper; an L-shaped side plate structure is welded and fixed on both sides of the bonding plate structure, and evenly arranged anti-slip teeth are fixed on the side edges of the side plate structure, and the anti-slip teeth of the pyramidal structure are inclined, and the anti-slip teeth are in contact with the sleepers.

[0007] The utility model provides an automatic track retracking device for mining, which has the following beneficial effects:

[0008] When a mine car derails, the rail clamp is controlled to connect to the track and is limited by the rerailing support plate on one side of the sleeper. Under the traction of the electric locomotive or winch, the driving wheels are guided by the guide ridges and the rerailing support plate and tilted toward the track, giving a certain centripetal force to the rerailing, forcing the wheels to move laterally to rerail when the mine car reaches the highest point along the inclined surface under the action of the guide ridges.

It also reduces the labor intensity of employees to a certain extent, improves transportation efficiency, and provides a strong guarantee for safe production in mines.

[0009] When the rerailer body is installed, the force-bearing structure is installed and used together. After the mine car wheels come into contact with the rerailer body, the force-bearing structure is squeezed through the rerailing support plate, so that the force-bearing structure eliminates the collision force and impact force through the force groove and its own material, effectively offsetting the impact effect.

[0010] After the track clamp has been used many times and is worn out, it needs to be replaced. At this time, the nuts of the connecting bolts can be loosened so that the connecting plate can be detached from the inside of the side groove, making it easy to detach the track clamp from the fixed connection with the track clamp body, making it convenient to replace the track clamp separately without cutting and then re-welding, which effectively improves maintenance efficiency.
