[0025] The following is combined with Figure 1 -Attached Figure 2 The utility model is described in further detail.

[0026] The embodiment of the utility model discloses a hydraulically controlled reversing device. Figure 1 The hydraulically controlled reversing device includes a crossbeam 1, a sling 2 slidably connected to the crossbeam 1, a hoist 3 detachably connected to the sling 2, and a driving mechanism 4 for driving the sling 2 to move back and forth.

[0027] Reference Figure 1 and Figure 2 The crossbeam 1 can be made of an I-steel structure and is fixedly installed on the top of the mine. The sling 2 includes a support plate 20, a roller 21 and a lifting ring 22. Two support plates 20 are vertically provided and are located on both sides of the crossbeam 1 respectively. Two groups of rollers 21 are provided and rotatably connected between the two support plates 20. Each group includes two rollers 21, one group of rollers 21 is rollingly supported on the top surface of the crossbeam 1, and the other group of rollers 21 is rollingly supported on the bottom surface of the crossbeam 1. The lifting ring 22 is fixed to the bottom ends of the two support plates 20. The lifting hoist 3 is hooked on the lifting ring 22. The lifting hoist 3 in this embodiment is a hand chain hoist.

[0028] Reference Figure 1 and Figure 2 In order to facilitate the installation of the roller 21, two sliding holes 200 are vertically arranged in parallel on the support plate 20. The roller 21 includes a fixed shaft 210 that passes through the sliding holes 200 corresponding to each other in the two support plates 20. A wheel sleeve 211 for rolling contact with the crossbeam 1 is rotatably sleeved on the fixed shaft 210. Both ends of the fixed shaft 210 are fixed to the support plate 20 by positioning nuts 212. A retaining ring 213 is also sleeved on the fixed shaft 210. The diameter of the retaining ring 213 is larger than the diameter of the wheel sleeve 211. The retaining ring 213 is fixed to the end of the wheel sleeve 211 and is located between the crossbeam 1 and the support plate 20.

[0029] Reference Figure 1 and Figure 2Two brushes 23 for cleaning the top surface of the beam 1 are installed between the tops of the two support plates 20, and the two rollers 21 located on the top surface of the beam 1 are located between the two brushes 23. The driving mechanism 4 includes a hydraulic motor 40 installed on the top surface of one end of the beam 1. The hydraulic motor 40 is used in conjunction with a hydraulic pump and an operating valve group. A driving sprocket 41 is installed on the output shaft of the hydraulic motor 40. A mounting seat 42 is provided on the top surface of the other end of the beam 1. A driven sprocket 43 is rotatably connected to the mounting seat 42. A chain 44 is installed in meshing relationship between the driving sprocket 41 and the driven sprocket 43. The chain 44 is connected to one of the support plates 20. When the chain 44 moves, it can drive the sling 2 to move.

[0030] Reference Figure 1 and Figure 2 To facilitate adjustment of the tension of the chain 44, a tensioning mechanism 5 is provided on the side of the mounting base 42 facing away from the hydraulic motor 40. A slideway 10 is provided along the length of the top surface of the crossbeam 1, and a slider is fixed to the bottom of the mounting base 42 for sliding engagement with the slideway 10. The tensioning mechanism 5 comprises a fixing plate 50 vertically fixed to the top surface of the crossbeam 1. A screw 51 is threaded transversely through the fixing plate 50. The end of the screw 51 is connected to a connecting block 52, which can be connected to the mounting base 42 by any existing connection method, such as a bearing. A fastening nut 53 is also threaded onto the screw 51 to secure it.

[0031] The hydraulically controlled reversing device of this embodiment works as follows: a crossbeam 1 spans between a 600mm-gauge mine car and a 900mm-gauge mine car. Before use, the spacing between the upper and lower sets of rollers 21 is adjusted according to the height of the crossbeam 1, while the tension of the chain 44 is adjusted by turning the screw 51. During use, the material on the mine car is tied up using the hoist 3, ensuring that no one is within the range of the spreader 2. The hoist 3, along with the material, is then hoisted onto the spreader 2.

[0032] The sling 2 is driven to move along the beam 1 by the hydraulic motor 40, the driving sprocket 41, the driven sprocket 43 and the chain 44. During the movement, the brush 23 cleans the possible debris on the top surface of the beam 1 in advance to avoid affecting the normal movement of the sling 2. When the sling 2 moves to the designated position, the hydraulic pump is turned off, and the hoist 3 and the material can be unloaded to the designated mine car, completing a material reversing operation.

[0033] The hydraulically controlled reversing device of the embodiment of the utility model is simple to operate, saves manpower, has a high safety factor, avoids industrial accidents when unloading materials on the mine car, and controls the source of harm to the operator, thereby ensuring safe operation.

[0034] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
