Device for preventing mine car from derailing and sliding through electromagnetic driving

Abstract

The invention discloses a device for preventing a mine car from derailing and sliding through electromagnetic driving. A supporting frame is welded at the bottom of the mine car; an action lever is arranged at the bottom end of the supporting frame through a movable pin shaft; the bottom end of a return tension spring is welded at the left end of the action lever; the top end of the return tensionspring is welded at the bottom of the mine car; a derailing and sliding preventing assembly is fixedly arranged at the left end of the action lever; a lever soft iron block is welded at the right endof the action lever; a lever driving electromagnet core is fixedly arranged at the bottom of the mine car over the lever soft iron block; a driving electromagnetic coil is wound on the lever drivingelectromagnet core; the action lever acts by an electromagnetic force generated by the lever driving electromagnet core after the driving electromagnetic coil is switched on; sliding and derailing arerealized through the derailing and sliding preventing assembly; and the device is scientific and reasonable in design, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a device for preventing derailment and rolling of a mine car by using electromagnetic drive, and belongs to the technical field of mine car auxiliary machinery. Background technique [0002] The mine car is a commonly used means of transportation in the underground roadway of the coal mine. There is a track for the mine car to run on the ground of the roadway, and the mine car runs along the track under the traction of the traction equipment. On the one hand, due to large changes in geological conditions, especially in roadways with large floor height changes, roadways with floor drums affected by mining, and inclined roadway transportation, derailment accidents are prone to occur in the existing mine car rail wheel transportation. It not only affects safe and effective transportation, but also is not conducive to safe and effective underground production. In the prior art, it is usually at the derailment place or the place wh...

Problems solved by technology

On the one hand, due to large changes in geological conditions, especially in roadways with large floor height changes, roadways with floor drums affected by mining, and inclined roadway transportation, derailment accidents are prone to occur in the existing mine car rail wheel transportation. Not only affects safe and effective transportation, but also is not conducive to safe and effective underground production

In the prior art, it is usually at the derailment place or the place where derailment is easy to occur, manually using steel pipes, wooden sticks and other supports to move the derailed bucket car back to the track or hold the mine car that is about to derail, and put sleepers under the mine wheel , and adjust the direction of the wheels of the mine car to prevent it from slipping off the rails; The mine carts squeezed each other, derailed the mine carts, and caused safety accidents

[0003] In view of the above problems, Chinese patent CN201320414336.3 discloses an anti-derailment device for coal mine cars, which can effectively reduce the problem of derailment of mine cars in practical applications, thereby reducing the workload of underground workers. The disadvantage is that it is not equipped with rails The hoop cannot adjust the fitting degree with the rail during use, and cannot effectively prevent the derailment of the mine car; Chinese patent CN201720381723.X discloses an anti-derailment device for a mine car. On the angle iron frame, there is a detachment ring in front of the angle iron frame, the detachment ring is connected with the drag ring cover, the rail hoop is connected with the hub, and the hub is provided with a bearing , the bearing is provided with fixing bolts, the bottom plate of the mine car is fixed above the wheel hub, the handle is fixedly connected with the coal mine car body, and the rail hoop includes a rail sleeve frame, a swing rod, and a regulating valve , hub protection plate, positioning nut, reinforcing rib, sleeve frame adjuster, connecting block, hydraulic cylinder, the rail sleeve frame is arranged under the swing rod, the swing rod is connected with the regulating valve, and the adjustment There is a hub protection plate on the left side of the valve, and a reinforcement rib is fixed on the hub protection plate, and a sleeve frame regulator is provided on the left side of the reinforcement rib, and the sleeve frame regulator is connected with the connecting block. There is a hydraulic cylinder on the right side of the connecting block

[0004] Both the above-mentioned anti-derailment device and the anti-crash car slipping device can only prevent the derailment or rolling of the mine car, and cannot realize the derailment and rolling of the mine car at the same time. At present, the existing technical solutions need to adopt two kinds of mechanical structures or device to realize the derailment and rolling of the mine car, which greatly increases the complexity of the technical solution, resulting in an increase in the weight of the mine car. The failure rate of the minecart during operation
