Description

Folding anti-slip baffle for coal transportation carriage Technical Field The invention belongs to the technical field of coal transportation equipment, and particularly relates to a folding anti-slip baffle for a coal transportation carriage. Background Coal transportation is used as a key link in an energy logistics system and carries an important task of efficiently and safely conveying coal from a mining place to consumption ends of power plants, steel plants, chemical enterprises and the like. In China, railways become a main mode of coal transportation due to the advantages of large transportation capacity, low cost, suitability for long-distance transportation and the like. As core equipment for railway coal transportation, the structural design of a transportation carriage is directly related to the overall performance, loading and unloading efficiency, transportation safety and environmental protection performance. At present, widely used coal transportation carriages adopt a rectangular box body structure, the top is open, the side wall is a fixed wallboard, and the bottom is designed to be a plane or provided with a certain gradient. In order to prevent coal from scattering in the transportation process, tarpaulin is covered on the top of a carriage in a manual or mechanical mode, and the mode is complex in operation and restricts the improvement of loading and unloading efficiency. In order to further reduce coal sliding, a part of carriages are additionally provided with fixed anti-skid baffles at the top, but the structure is difficult to adapt to diversified transportation conditions and loading and unloading requirements For example, chinese patent publication No. CN222388983U discloses a lifting and transporting device for inclined drifts of coal mines, which is provided with a fixed baffle plate at one side of the top of the loading box, and can prevent coal from falling to a track to a certain extent by matching with a protection plate and an inclined sliding plate at two sides of the base. However, the baffle is of a fixed structure, cannot be folded or rotated, lacks adaptability to complex transportation scenes (for example, loading and unloading coal), and has the problems of single function, limited use and the like. In order to overcome the defects of unadjustable baffle plates, limited application range and the like in the prior art, the invention provides a folding anti-slip baffle plate for a coal transportation carriage, so as to improve the functionality and scene adaptation capability of the baffle plate. Disclosure of Invention In order to solve the problems in the prior art, the invention provides the folding type anti-skid baffle for the coal transportation carriage, which has the characteristics of convenient use, easy adjustment and wide application range. In order to achieve the aim, the invention provides the technical scheme that the folding anti-slip baffle of the coal transportation carriage comprises a baffle main body and a connecting component, wherein the baffle main body is arranged at the top of the side wall of the coal transportation carriage, and the connecting component is used for connecting the baffle main body to the coal transportation carriage; The connecting assembly comprises a lower fixed beam and an upper fixed beam which can rotate relatively, the lower fixed beam is fixedly connected to the side wall of the coal transportation carriage, and the upper fixed beam is rotatably connected with the baffle main body; A first locking mechanism is arranged between the lower fixed beam and the upper fixed beam and used for fixing the upper fixed beam which can rotate relative to the lower fixed beam. The baffle main bodies are at least two and are sequentially hinged in the vertical direction; the upper fixed beam is rotationally connected with the baffle main body positioned at the bottom layer. The first locking mechanism comprises a first positioning block; The first positioning block is fixedly arranged at the top of the lower fixed beam and used for limiting the rotation position of the upper fixed beam. The upper fixing beam is provided with a positioning groove corresponding to the first positioning block, and when the upper fixing beam rotates to be positioned on the same vertical plane with the lower fixing beam, the first positioning block is matched with the positioning groove so that the upper fixing beam is fixed relative to the lower fixing beam; The first locking mechanism further comprises a first bolt, and the first bolt penetrates through the first positioning block to be in threaded connection with the upper fixing beam. The second locking mechanism is used for fixing the baffle main body in the vertical state to the upper fixing beam; The second locking mechanism comprises a second positioning block and a second bolt, the two second positioning blocks are symmetrically fixed at two ends of the upper fixed beam, and the second bolt penet
