In the invention, steel materials with the thickness of 40-60mm are selected as the bottom plate 3 and the side plate 4 of the carrying mine car, in some specific embodiments, the bottom plate 3 of the carriage of the mine car provided by the invention is selected from rectangular steel plates, the lengths of the side plate I4-1 and the side plate II 4-2 are equal to the width of the rectangular steel plates, and the lengths of the side plate III 4-3 and the side plate IV 4-4 are equal to the length of the rectangular steel plates. In some more specific embodiments, side panels I4-1 and II 4-2 are 1.5m-2m in length and side panels III 4-3 and IV 4-4 are 2.5m-4m in length.
As shown in fig. 5, two hydraulic jacks 7 are symmetrically arranged on a side plate II 4-2 of the carrying mine car, and the carriage bottom plate 3 and the ground form a certain inclination angle by adjusting the supporting force action of the hydraulic jacks 7 and the ground. The base of the hydraulic jack 7 is fixed on the outer side wall of the rear side plate 4-2, and the top bracket of the hydraulic jack 7 vertically contacts with the ground downwards, so that the stability of the carrying mine car is improved.
As shown in fig. 2, a clamping groove 5 is correspondingly formed at the connection position of the adjacent side plates 4 in the carriage 1, and two ends of the L-shaped limiting plate 6 are respectively clamped in the clamping groove 5, so that the side plates i 4-1, ii 4-2, iii 4-3 and iv 4-4 can be relatively fixed to form the carriage 1 with an upward opening and capable of accommodating cargoes. In some embodiments, the L-shaped limiting plate 6 may be movably connected to the side plate 4 for convenience, for example, a chain may be used to hang the L-shaped limiting plate 6 on the side plate 4.
As shown in fig. 3, a mounting hole 9 for fixing the lifting oil cylinder 8 is formed in the side plate I4-1, and the side plate II 4-2 is similar; the lifting cylinder 8 is fixed on the inner walls of the side plate I4-1 and the side plate II 4-2 through the mounting holes 9, for example, fixed by fixing pins and the like. The base of the lifting oil cylinder 8 is fixed on the side plate I4-1 and the side plate II 4-2, and the power output end of the lifting oil cylinder 8 faces the interior of the carriage 1. When large equipment or irregular material accessories are required to be carried into a carriage of the mine car, the power output end of the lifting cylinder 8 is adjusted through the control system to adjust the length and the height of the power output end, after the power output end is adjusted to the loading position of the goods, the lifting hook of the power output end is fixed with the goods, and the telescopic length of the power output end is controlled to lift the goods to be lifted to the appointed position in the carriage, so that the lifting and carrying functions of the heavy goods in a narrow space of the carrying mine car are realized, the operation is simple, and the safety coefficient is high.

As shown in fig. 4, the direction in which the reinforcing bead 10 extends is perpendicular to the directions of the side plates i 4-1 and ii 4-2.
If equipment faults, damages and other conditions occur on the fully mechanized mining face and the like, the carrying mine car is loaded at a storage place of a part fitting and the like, the L-shaped limiting plate 6 on the side plate 4 (for example, the side plate III 4-3) close to one side of the loading place is taken out from the clamping groove 5, the bottom edge of the side plate III 4-3 is hinged with the bottom plate 3, the height of the side plate III 4-3 is larger than the distance between the bottom plate 3 and the ground, and after the L-shaped limiting plate 6 is taken down, the side plate III 4-3 can turn to the outer side of the axial carriage 1 by taking the hinge shaft as a rotation axis to be in contact with the ground. After the side plate III 4-3 is contacted with the ground, a small inclined plane with a certain angle is formed between the bottom plate 3 and the ground, and an operator can lift or slide goods through the inclined plane, so that the labor intensity of the operator in the loading process is reduced.
Meanwhile, the operator can press the hydraulic jack 7 close to the side plate iv 4-4 in the above process, and as the top bracket of the hydraulic jack 7 collides with the ground and the supporting force between the top bracket of the hydraulic jack 7 and the ground increases gradually in the pressing process, the side plate iv 4-4 is lifted upwards relative to the side plate iii 4-3, so that the bottom plate 3 forms a "large inclined plane" with the ground after being inclined to the loading place. The goods such as the parts and accessories to be carried are carried under the combined actions of the small inclined plane and the large inclined plane, so that the labor intensity in the carrying process is further reduced, and the carrying working efficiency is further improved.
After the parts to be carried are carried to the mine car, the supporting pressure between the top base of the hydraulic jack 7 and the ground is restored to zero, and the original state is restored to complete the loading work. Then, the side plate III 4-3 is turned around the hinge shaft as the inner side of the rotary axial carriage 1 until the side plate III 4-3 is close to the side plates I4-1 and II 4-2, and the L-shaped limiting plate 6 is clamped in the corresponding clamping grooves 5 of the side plates I4-1 and III 4-3 and the side plates II 4-2 and III 4-3. Finally, the carrying mine car adopts the original rail transportation, and the goods such as the parts fittings and the like are transported to the appointed place of the fully mechanized mining face. In the same way, in the unloading process of the goods such as the parts and accessories, the goods can be unloaded by means of the angles of the large inclined plane and the small inclined plane, so that the labor intensity in the carrying process is reduced.
When heavy objects or irregular goods need to be carried or unloaded, the control system of the lifting oil cylinder 8 is controlled to adjust the length and the height of the power output end, the lifting hook at the power output end is close to the goods and fixes the goods with the lifting hook, and the lifting hook is lifted to a designated position by adjusting the telescopic length of the power output end.
Although the present invention has been described in terms of the specific embodiments thereof, the present invention is not limited thereto, and the embodiments are merely illustrative of the present invention. Any person skilled in the art can make any modification and variation in form and detail without departing from the spirit and scope of the present disclosure, but the scope of the present disclosure is still subject to the scope of the appended claims.
