Description

Technical Field

[0001] The utility model belongs to the field of coal mine track periphery, in particular to an adjustable turnout pull rod special for coal mines. Background Art

[0002] Mine cars are special vehicles for mine rail transportation. In order to adapt to the narrow conditions of underground tunnels, the size is compact. There are trucks, man-carriages, material cars, etc. Mine cars are narrow-gauge railway transport vehicles for transporting bulk materials such as coal, ore and waste rock in mines, and generally need to be towed by locomotives or winches.

[0003] At present, the mine car lane change is mainly achieved by using hydraulic or pneumatic devices to push the mine car from one track to another. This will cause certain damage to the wheels of the mine car. In addition, due to the frequent accumulation of coal slag on the mine car track, the path of pushing the track change will be blocked, resulting in the failure of the track change device. After a long period of actual use, the existing mine track uses a turnout pull rod. The connecting bolts at both ends of the pull rod and the pull rod itself will loosen and deform to varying degrees. During the operation of the vehicle, if the pull rod is not tightened or tightened, there is a possibility of falling off the track during the lane change. Although this deformation is very small, it cannot be ignored for coal mine transportation. Utility Model Content

[0004] The utility model aims to provide an adjustable turnout pull rod specially used in coal mines, so as to solve the problem of potential safety hazards in changing lanes of mine cars caused by deformation of the turnout pull rod.

[0005] The utility model adopts the following technical scheme: an adjustable turnout pull rod for coal mines, comprising:

[0006] The first turnout tie rod has a right end connected to the pneumatic turnout box and a left end disposed close to the track and extending toward the track; the first turnout tie rod is in a "z" shape;

[0007] The second turnout rod has a left end fixedly connected to the track and a right end disposed close to the first turnout rod;

[0008] A connecting sleeve, the right end of which is sleeved on the left end of the first turnout rod and threadedly connected to the left end of the first turnout rod, and the left end of which is sleeved on the right end of the second turnout rod and threadedly connected to the right end of the second turnout rod; used to offset the deformation of the first turnout rod and the second turnout rod by changing the length of the first turnout rod and the second turnout rod extending into the connecting sleeve;

[0009] The reinforcement mechanism is sleeved on the first turnout pull rod and the second turnout pull rod, and is used to assist the connection sleeve to maintain the distance between the first turnout pull rod and the second turnout pull rod, so as to facilitate accurate track changing.

[0010] Furthermore, the reinforcement mechanism comprises:

[0011] The first pull rod ring is sleeved on the first pull rod of the turnout and is threadedly connected with the first pull rod of the turnout;

[0012] The second pull rod ring is sleeved on the second pull rod of the turnout and is threadedly connected with the second pull rod of the turnout;

[0013] A first reinforced arc-shaped plate, the right end of which is fixedly connected to the left side of the first sleeve ring of the pull rod;

[0014] The second reinforced arc-shaped plate has a left end fixedly connected to the right side of the second sleeve ring of the pull rod, and a fixing groove is opened from right to left at the right end of the plate, the fixing groove is arc-shaped and is used for the left end of the first reinforced arc-shaped plate to extend therein;

[0015] A plurality of reinforcing screws are used to pass through the outer wall of the reinforced second arc plate and extend into the fixed groove to abut against the left end of the reinforced first arc plate, thereby clamping the reinforced first arc plate to prevent the reinforced first arc plate from loosening, thereby ensuring the distance between the first turnout pull rod and the second turnout pull rod, facilitating accurate track changing.

[0016] The beneficial effects of the utility model are:

[0017] The utility model adjusts and tightens the first turnout pull rod and the second turnout pull rod by setting a connecting sleeve, and then tightens the first turnout pull rod and the second turnout pull rod by a reinforcement mechanism, which provides double insurance and avoids safety hazards caused by deformation of the turnout pull rod when the mine car changes lanes.

[0018] The utility model is easy to adjust, and the deformation of the first turnout pull rod and the second turnout pull rod can be offset by adjusting the length of the first turnout pull rod and the second turnout pull rod extending into the connecting sleeve. It is simpler and more practical in use and maintenance, and can reduce the number of times the pull rods are replaced and reduce maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
