Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in figures 1, 2 and 3, the anti-falling device for the mine underground side-dumping mine car chute comprises a rail 1 and a mounting plate 2, wherein the rail 1 is attached to the mounting plate 2, a towing mechanism 3 for fixing a mine car is arranged on the rail 1, a hole groove 4 corresponding to a well mouth is formed in the mounting plate 2, an anti-falling mechanism 5 is also arranged on the mounting plate 2 and used for resisting the mine car to fall down, in some embodiments, the anti-falling mechanism 5 is arranged for resisting the coming and going mine cars, so that the condition that the mine cars fall into the mine well to cause casualties and damage of the mine cars is avoided when the mine cars slide down, meanwhile, when the mine cars stop at the well mouths of the mine, the mine cars can be fixed at the moment by the action of the towing mechanism 3 to avoid overturning and causing accidents, and meanwhile, the problem that the existing anti-falling device only utilizes the action of railings to block the side-tipping mine cars to avoid falling events, but because the bearing capacity of railing is limited, can't play fine anti-falling effect to heavier mine car, more specifically be, when the mine car goes to well head limit on track 1, the anti-falling mechanism 5 on the accessible mounting panel 2 blocks the mine car and contradicts, has avoided the mine car to slide the car upset and has leaded to it to fall into the well, and when the mine car stopped at well head limit, the staff can drive to drag 3 hooks of hitch constructs and hang on the mine car to this avoids the mine car when getting in good, leads to the condition of empting to the well because the mine car is overweight.

As shown in fig. 1, in some embodiments, the towing mechanism 3 includes a straight rod 31 vertically fixed on the rail 1, and the end of the straight rod 31 far from the rail 1 is fixed with a loop 32 through a support rod, and a steel wire rope 33 is fixedly sleeved on the loop 32, and the end of the steel wire rope 33 far from the loop 32 is fixed with a hook 34, and the hook 34 is used for hooking on the mine car, more specifically, when the mine car runs to a certain position on the rail 1, the steel wire rope 33 wound on the straight rod 31 can be firstly taken off, and then the hook 34 on the steel wire rope 33 can be used for hooking on the mine car, thereby avoiding the situation that the mine car rolls over at the well opening side and causes the falling of the mine car.

As shown in fig. 1, 2 and 3, in some embodiments, the anti-falling mechanism 5 includes sliding grooves 51 symmetrically formed on the mounting plate 2, and sliding blocks 52 are slidably connected inside the two sliding grooves 51, and one end of each of the two sliding blocks 52 away from the sliding groove 51 is fixedly connected with a U-shaped plate 53, and a U-shaped plate 54 corresponding to the U-shaped plate 53 is also fixedly arranged on the mounting plate 2, and the U-shaped plate 53 is connected with the U-shaped plate 54 through two springs 55, and further includes a protection mechanism 56 arranged on the mounting plate 2 and used for protecting a mine car, more specifically, it should be noted that, when the mine car falls down to a wellhead, the U-shaped plate 54 is firstly contacted, and when the U-shaped plate 54 is impacted by the mine car, the sliding blocks 52 thereon are driven to slide along the length of the sliding grooves 51, and when the U-shaped plate 53 slides to a certain position, the U-shaped plate 53 abuts against the U-shaped plate 53 on the mounting plate 2, therefore, the toppled mine car is supported, and the situation of falling into the well is avoided, wherein it needs to be described that the mine car toppled over on the U-shaped plate I53 can be buffered to a certain extent through the action of the two springs 55, so that the instant impact force of toppling over of the mine car is weakened, and finally, it is possible that the toppled mine car cannot be supported by the U-shaped plate I53 and the U-shaped plate II 54 under the situation that the coal mine loaded in the mine car is too heavy and toppled over occurs, the mine car can be secondarily supported by the protection mechanism 56 at the moment, and the occurrence of the event that the overweight mine car topples into the well is avoided.

As shown in fig. 2, in some embodiments, a plurality of through holes 6 are formed in the mounting plate 2 along the periphery of the thickness direction thereof, and bolts 7 are slidably connected to the inside of the through holes 6, and the bolts 7 are used for penetrating through the through holes 6 and being inserted into the ground, more specifically, when the mounting plate 2 is placed on the ground corresponding to the wellhead, the bolts 7 penetrate through the through holes 6 and are inserted into slots reserved on the ground in advance, so that the mounting plate 2 can be integrally fixed on the ground.

As shown in fig. 1 and 2, in some embodiments, the straight rod 31 is provided with the circular rings 8 arranged along the length direction thereof, and both the circular rings 8 are fixed on the straight rod 31, and the circular rings 8 are used for fixing the wire rope 33 wound on the straight rod 31, more specifically, when the wire rope 33 is wound on the straight rod 31, the two circular rings 8 protruding from the straight rod 31 can be used to prevent the wire rope 33 wound on the upper end of the straight rod 31 from sliding down to the lower end of the straight rod 31, so that the wire rope 33 wound on the straight rod 31 is accumulated on the lower end thereof, which may cause the wire rope 33 to be wound on the straight rod 31 between the wire ropes 33 to be disordered, and the straight rod 31 cannot be used properly.

As shown in fig. 1, 2 and 3, in some embodiments, the protection mechanism 56 includes a guide rod 561 fixed on the U-shaped plate 53 and configured to slidably penetrate through the U-shaped plate 54, and a through hole 562 is vertically formed at an end of the guide rod 561 away from the U-shaped plate 53, and a roller 563 is rotatably disposed inside the through hole 562 through a round rod, and a circular hole for the guide rod 561 to pass through is further formed on the U-shaped plate 54, and further includes a contact plate 564 hinged on the mounting plate 2, and the contact plate 564 is provided with a rolling groove 565 adapted to the roller 563 along a height direction thereof, more specifically, when the tramcar contacts the U-shaped plate 53 in a dumping manner, the guide rod 561 thereon is also driven to slide in the circular hole formed on the U-shaped plate 54 by movement of the U-shaped plate 53, and the roller 563 at the through hole 562 is driven while the guide rod slides, so that the contact plate 564 rotates around the hinge point thereof and forms an inclined state, therefore, the side-turned mine car can be supported for the second time, the mine car is prevented from falling into a well, and it needs to be explained here that when the roller 563 drives the contact plate 564, the roller 563 slides along the length of the rolling groove 565 formed in the contact plate 564, so that the guide rod 561 can drive the contact plate 564 to rotate around the hinge point under the condition that the angle of the guide rod 561 is not changed, and the rotated contact plate 564 abuts against the U-shaped plate 54.
