[0002] At present, in the process of coal mining, a large number of operations are completed underground. There are vertical shafts and inclined shafts underground. When mining, equipment needs to be moved through the tunnels. For example, equipment for hydraulic support, detection instruments, etc., all need to be moved underground. With the large-scale promotion and application of comprehensive mechanized mining and excavation working faces in coal mines, the mechanization level of comprehensive mining and comprehensive excavation has been continuously improved, and the corresponding auxiliary transportation tasks have also increased significantly. In addition, with the continuous improvement of the level of comprehensive mechanized equipment in coal mines, coal mining equipment has developed in the direction of heavy load and large-scale. Especially for large mining height working faces, high-power coal mining machines and comprehensive mining hydraulic supports used for support are large in size and heavy in weight.

[0003] Now underground transportation in coal mines mainly uses the transportation mode of wire rope traction railcar to realize the transportation of underground equipment. Underground transportation vehicle in coal mines is a commonly used means of transportation in underground tunnels in coal mines. The track for the operation of a mine car is provided on the tunnel surface, and the mine car runs along the track under the traction of a traction device. Existing rail transportation equipment is mainly divided into a single track type and a double track type. Usually, an anti-derailing slide plate is installed at the bottom of the rail vehicle, extending to the ground track. When the vehicle is offset, the anti-derailing slide plate will contact the inner side of the track to prevent the track from derailing. However, traditional transportation equipment is very easy to wear between the rail wheel and the rail during use, thereby causing derailment in transportation, and the safety performance is insufficient, and the applicability is relatively limited. Summary of the invention

[0004] In order to overcome the defects of traditional transportation equipment in the prior art that the track wheels and the rails are very easy to wear during use, thereby causing derailment during transportation and insufficient safety performance, the present invention provides an anti-falling track transportation equipment for transporting materials in underground coal mines.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an anti-falling track transportation equipment for underground material transportation in a coal mine, comprising symmetrically arranged track beams and a transportation device, wherein the upper surface of each track beam is fixedly installed with a rail, the transportation device is installed on the rail, and anti-derail components are fixedly installed at the bottom ends of both sides of the transportation device, the anti-derail components comprising a fixed shaft, the outer surface of the fixed shaft is sleeved with a mobile pressing block, one end of the fixed shaft away from the mobile pressing block is fixedly installed with a connecting seat, the outer wall of the fixed shaft between the mobile pressing block and the connecting seat is sleeved with a reset spring, the reset spring is fixedly connected to the mobile pressing block, both sides of the connecting seat are rotatably connected with pressure rods, the inner surface of the pressure rod is provided with a movable groove, both sides of the mobile pressing block are rotatably connected with connecting rods, one end of the connecting rod away from the mobile pressing block is rotatably connected with the pressure rod, the lower surface of the pressure rod end is fixedly connected with a connecting column, and the lower surface of the connecting column is rotatably connected with a roller.

[0006] As a further improvement of the present invention, the transport device includes a base plate, a transport vehicle is fixedly mounted on the upper surface of the base plate, moving components are symmetrically arranged on the lower surface of the base plate, and a side surface of the base plate is fixedly connected to the fixed shaft.

[0007] As a further improvement of the present invention, the moving assembly includes symmetrically arranged cross beams, the inner sides of the symmetrically arranged cross beams are rotatably connected to two connecting shafts, and both sides of each connecting shaft are actively rotatably connected to track wheels.

[0008] As a further improvement of the present invention, a shock absorbing assembly is fixedly installed on the inner side of the symmetrically arranged cross beams.

[0009] As a further improvement of the present invention, the shock absorbing assembly includes a shock absorbing base, a pressure column is fixedly mounted on the bottom surface of the shock absorbing base, and a shock absorbing spring is sleeved on the outer surface of the pressure column.

[0010] As a further improvement of the present invention, towing hooks are fixedly installed on both the front and rear sides of the bottom plate.

DETAILED DESCRIPTION

[0020] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] Embodiment 1: Reference Figure 1 and Figure 2 In order to prevent a transport vehicle 4 from derailing during the material transportation process, the present invention discloses an anti-falling rail transport device for transporting materials in underground coal mines, comprising a symmetrically arranged rail beam 1 and a transport device, wherein a steel rail 2 is fixedly mounted on the upper surface of each rail beam 1, the transport device is mounted on the steel rail 2, and anti-derail components are fixedly mounted on the bottom ends of both sides of the transport device, the anti-derail components comprising a fixed shaft 14, a movable pressing block 15 is sleeved on the outer surface of the fixed shaft 14, and a connecting seat 1 is fixedly mounted on one end of the fixed shaft 14 away from the movable pressing block 15 7. A return spring 16 is sleeved on the outer wall of the fixed shaft 14 between the movable pressure block 15 and the connecting seat 17. The return spring 16 is fixedly connected to the movable pressure block 15. Pressure rods 19 are rotatably connected to both sides of the connecting seat 17. A movable groove 20 is provided on the inner surface of the pressure rod 19. Connecting rods 18 are rotatably connected to both sides of the movable pressure block 15. One end of the connecting rod 18 away from the movable pressure block 15 is rotatably connected to the pressure rod 19. A connecting column 21 is fixedly connected to the lower surface of the end of the pressure rod 19. A roller 22 is rotatably connected to the lower surface of the connecting column 21. By pressing the roller 22 against the outer side of the track beam 1 by the pressure rod 19 and making contact with it, the edge of the track wheel 7 can be prevented from excessively rubbing against the rail 2 and causing derailment. When the transport vehicle 4 deviates, the angle between the transport vehicle 4 and the track beam 1 will deviate. The rebound force of the reset spring 16 can increase the squeezing force of the roller 22 on the track beam 1, which can correct and reset the transport vehicle 4. It can effectively prevent the transport vehicle 4 from derailing accidents caused by uneven tracks, overspeeding, etc. during transportation, thereby protecting the safety of operators and transported materials. Reducing accidents and wear helps to extend the service life of the track and the transport vehicle 4 and reduce long-term operating costs.

[0022] Embodiment 2: Reference Figure 3 and Figure 4, on the basis of the first embodiment, in order to realize the shock absorption of the transport vehicle 4 in the process of transporting materials, the transport device includes a bottom plate 3, the upper surface of the bottom plate 3 is fixedly mounted with the transport vehicle 4, the lower surface of the bottom plate 3 is symmetrically provided with a moving assembly, and the side surface of the bottom plate 3 is fixedly connected to the fixed shaft 14. The moving assembly includes a symmetrically arranged crossbeam 8, the inner side of the symmetrically arranged crossbeam 8 is rotatably connected with two connecting shafts 6, and the two sides of each connecting shaft 6 are actively rotatably connected with track wheels 7. The inner side of the symmetrically arranged crossbeam 8 is fixedly mounted with a shock absorbing assembly. The transport device includes a bottom plate 3, the upper surface of the bottom plate 3 is fixedly mounted with the transport vehicle 4, the lower surface of the bottom plate 3 is symmetrically provided with a moving assembly, and the side surface of the bottom plate 3 is fixedly connected to the fixed shaft 14. The moving assembly includes a symmetrically arranged crossbeam 8, the inner side of the symmetrically arranged crossbeam 8 is rotatably connected with two connecting shafts 6, and the two sides of each connecting shaft 6 are actively rotatably connected with track wheels 7. The inner side of the symmetrically arranged crossbeam 8 is fixedly mounted with a shock absorbing assembly. When the transport vehicle 4 passes through an uneven track or there are stones on the track, the shock-absorbing base 11 presses down the pressure column 12, driving the shock-absorbing spring 13 on the pressure column 12. Through the rebound performance of the shock-absorbing spring 13, the crossbeam 8 is buffered and shock-absorbed, thereby reducing the wear on the track wheel 7 and increasing the service life.

[0023] Working principle: When using this device, first of all, in order to prevent the transport vehicle 4 from derailing during the material transportation process, the roller 22 is attached to the outer side of the track beam 1 through the pressure rod 19 to contact it, which can prevent the edge of the track wheel 7 from excessively rubbing against the rail 2 and causing derailment. When the transport vehicle 4 deviates, the angle between the transport vehicle 4 and the track beam 1 will deviate. The rebound force of the reset spring 16 can increase the squeezing force of the roller 22 on the track beam 1, which can correct the deviation and reset the transport vehicle 4, and can effectively prevent the transport vehicle 4 from being derailed due to uneven tracks, overspeeding, etc. during transportation. Derailment accidents caused by the reasons can be prevented, thereby protecting the safety of operators and transported materials, and reducing accidents and wear helps to extend the service life of the track and the transport vehicle 4, and reduce long-term operating costs. Secondly, in order to achieve shock absorption of the transport vehicle 4 in the process of transporting materials and improve its service life, when the transport vehicle 4 passes through an uneven track or there are stones on the track, the shock-absorbing base 11 presses down the pressure column 12, driving the shock-absorbing spring 13 on the pressure column 12, and through the rebound performance of the shock-absorbing spring 13, the crossbeam 8 is buffered and damped, thereby reducing the wear on the track wheel 7 and improving the service life.

[0024] Towing hooks 5 are fixedly installed on both the front and rear sides of the bottom plate 3 for easy hooking of the trailer. A steering device 9 acting on the track wheel 7 is arranged on the side surface of the cross beam 8. The steering device 9 can be used to adjust the direction of the track wheel 7 so that the track wheel 7 fits the rail 2 closely. A brake pad 10 is arranged on the outside of the track wheel 7 for timely and effective braking in case of an emergency.
