[0001] The present invention relates to the field of single column transportation in coal mines, and in particular to a single column advance and portable transportation slideway vehicle for fully mechanized mining working faces. Background Art

[0002] According to the coal mining design specifications, the Carboniferous system is affected by the air-prone goaf, and the advance support distance must be maintained at least 100 meters. The current single column diameter of the chute support is 110 mm, the support height is 4.5 meters, and each single column weighs 220 kilograms. Based on the calculation of advancing 6 meters per day, two people must work together to carry 220 kilograms for 2400-2800 meters. The workers who carry out the advance support at the tail of the fully mechanized mining face have a huge workload and heavy tasks. Work-related injuries occur frequently, affecting production efficiency. During the years of heavy labor, support workers often suffer from diseases such as lumbar muscle strain and lumbar disc herniation. In order to reduce the labor intensity of workers, reduce work-related injuries, and improve work efficiency, it is necessary to improve the existing single column transportation method. Summary of the Invention

[0003] In order to solve the problem of huge workload and heavy tasks for workers in the existing transportation of single columns, which easily leads to work-related injuries and affects production efficiency, the present invention provides an advanced and lightweight single-column transportation slide car for comprehensive mining working faces. This slide car changes the existing transportation method and is a new type of transportation tool.

[0004] The present invention is realized through the following technical scheme: a single-column slide vehicle for advanced and portable transportation of a comprehensive mining working face, comprising a slide, multiple bases and multiple pulleys; the slide is formed by connecting multiple slide main beams, and adjacent slide main beams are connected by slide connection assemblies; the connection between adjacent slide main beams is supported by a base, and the pulley is arranged on the slide main beam. The slideway main beam includes two opposing L-shaped rails, which are connected as a whole by a plurality of rail crossbeams. The two ends of the two L-shaped rails are connected by two connecting plates, and the connecting plates have two bolt holes for connecting to the slideway connecting assembly. The slideway connecting assembly includes an upper mounting plate, a lower mounting plate, and two angle irons, the two angle irons facing each other, the upper mounting plate and the lower mounting plate connected between the two angle irons, and a gap is left between the upper mounting plate and the lower mounting plate for inserting the connecting plate. The upper mounting plate and the lower mounting plate each have two pairs of bolt holes, and the bolt holes are matched with the bolt holes on the adjacent slideway main beam connecting plates. The upper mounting plate and the lower mounting plate are connected to the connecting plate by bolts. The base includes a cross fixing seat and a support column, the support column is vertically fixed at the center of the cross fixing seat, and the top of the support column is fixedly connected to the bottom surface of the lower mounting plate. The cam is secured to the chassis and has an L-shaped track, and the cam is secured to the chassis by means of a lever, and the cam is secured to the chassis by means of a lever, and the cam is secured to the chassis by means of a lever.

[0005] The present invention provides a single-column advance and lightweight transport slide vehicle for a fully-mechanized mining working face. It is mainly an improvement on the transportation method of single columns. A slide is set up on the fully-mechanized mining working face, which is similar to a track. After the single column is placed on a special pulley, it is moved along the slide to the installation location of the single column. The slide vehicle mainly includes a slide, multiple bases and multiple pulleys; the pulley is used to place the single column and is set on the slide main beam; the base is used to support the slide, and the slide is the track for the pulley to run. The slide is connected by multiple slide main beams, and adjacent slide main beams are connected by slide connection components; the connection between adjacent slide main beams is supported by the base. The slideway main beam includes two opposing L-shaped rails, each made of long angle iron. The two L-shaped rails are connected as a whole by multiple rail crossbeams. The rail crossbeams not only serve as a connection but also serve to strengthen the entire slideway main beam. The two ends of the two L-shaped rails are connected by two connecting plates. The two connecting plates are used to insert into the slideway connecting assembly to complete the connection with the adjacent slideway main beam. The connecting plates are provided with two bolt holes for connecting to the slideway connecting assembly, which are used to be bolted to the slideway connecting assembly. The slideway connecting assembly includes an upper mounting plate, a lower mounting plate and two angle irons. The two angle irons are opposite each other. The upper mounting plate and the lower mounting plate are connected between the two angle irons, and a gap is left between the two to allow the connecting plate to be inserted. The upper mounting plate and the lower mounting plate each have two pairs of bolt holes. The bolt holes match the bolt holes on the connecting plates of the two adjacent slideway main beams. When the connecting plates are inserted, the connecting plates on both sides can be bolted to the upper and lower mounting plates as a whole, thereby connecting the adjacent slideway main beams. The base includes a cross-mounted base and a support column. The cross-mounted base acts as a base stabilization mechanism. The support column is vertically fixed at the center of the cross-mounted base. The top of the support column is fixedly connected to the bottom surface of the lower mounting plate and supported at the connection point of the adjacent slide main beams. The base as a whole elevates the slide, allowing it to be transported away from the ground. The pulley mainly includes a moving plate and a moving wheel assembly. The moving plate is rectangular in shape, with two sets of single-column support frames evenly distributed in the middle for accommodating the single columns. Two or three pulleys can be used to accommodate the entire single column. A set of moving wheels is installed at the bottom of each of the four corners of the moving plate. Each set of moving wheels includes a main sliding wheel and a side guide wheel. The main sliding wheel has a horizontal axis and moves along the extension direction of the slide, providing support and movement. The main sliding wheel rolls along the horizontal portion of the L-shaped track when the pulley moves. The side guide wheels have an axis perpendicular to the ground and move along the extension direction of the slide, providing guidance. The side guide wheels roll against the vertical side walls of the L-shaped track when the pulley moves, making this structure easy to slide.

[0006] The specific operation of the present invention is as follows: first, lay the slide, from the starting point to the single column installation point, insert multiple slide main beams into the upper and lower mounting plates of the slide connection assembly through the connecting plates on both sides, align the corresponding bolt holes, and tighten them with bolts. Since the support columns of the base are fixed to the bottom surface of the lower mounting plate, after the adjacent slide main beams are assembled, the base fixes the slide main beams at a certain height; when it is necessary to transport the single column, place multiple pulleys on the slide, and then place the head and tail of the single column on the single column support frames corresponding to the multiple pulleys, and use multiple pulleys to transport the single column; then use manual traction pulleys to move the single column along the slide, and the side guide wheels are used for guidance. The main sliding wheel moves the movable plate until it moves into place, and then it is transported down from the pulley.

[0007] Preferably, the support frame includes two symmetrical support steel plates, which are fixed on the movable plate, and a concave position space for placing the single column is formed between the two symmetrical support steel plates; generally, each single column is transported by 2 to 3 pulleys.

[0008] Preferably, the main sliding wheel and the side guide wheel both use deep groove ball bearings and are equipped with dustproof rings to prevent dust.

[0009] Preferably, the overall height of the slide vehicle is 300 mm, in order to lower the center of gravity as much as possible and maintain stability after loading the single column.

[0010] Compared with the prior art, the present invention has the following beneficial effects: the light-weight slideway for transporting single columns in advance of the comprehensive mining working face provided by the present invention has the characteristics of being detachable, assembling, light in weight and high in strength; it is simple to manufacture, low in cost, high in strength, easy to slide, stable in sliding, simple to operate, and has a long life cycle of dustproof bearings, and other parts can also be replaced; it completely changes the previous method of manually carrying and transporting single columns by relying on great strength, while fully considering the height of the single column lifted and lowered by the operators and the firmness of the slideway, changing from manual carrying to sliding, saving time and effort, and being safe and efficient. After the present invention is put into use, the labor intensity of the workers will be greatly reduced, and the support task that was previously barely completed by six people can be easily completed by four people, saving 2,000 yuan in support labor costs per day, and at the same time, personnel can be drawn out to supplement standardization construction and improve the level of on-site management; it improves production efficiency; and has broad prospects for use.
