[0024] The following embodiments are described in detail, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numbers in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following embodiments are not intended to represent all possible implementations consistent with the present application. They are merely examples of systems and methods consistent with certain aspects of the present application, as detailed in the claims.
[0025] An underground flatbed truck is a type of equipment specifically used for transportation in underground mines and underground tunnels. It is a rail-type transport vehicle. Underground flatbed trucks are mainly used to carry large amounts of materials and equipment, such as coal, rock, and ore in coal mines, as well as stone, building materials, and hydraulic supports in underground tunnels. Loading these materials on a flatbed truck allows them to be quickly and safely transported from underground or in underground tunnels to designated locations, thereby improving production efficiency and work effectiveness. When an underground flatbed truck transports heavy materials to an intersection or an intersection with a large curve, the underground flatbed truck is difficult to pass due to the large volume of the heavy materials. It is necessary to lift the underground flatbed truck with a crane and then manually adjust the direction of the flatbed truck to allow it to pass through the intersection or the intersection with a large curve. This can be dangerous, and the transportation efficiency of underground flatbed trucks is low.
[0026] To solve the problem of low transportation efficiency of underground flatbed trucks, see Figure 1 and Figure 2 , Figure 1 This is a front view of the underground rotatable flatbed vehicle provided in an embodiment of the present application. Figure 2 This is a top view of an underground rotatable flatbed truck provided in an embodiment of the present application. The embodiment of the present application provides an underground rotatable flatbed truck, including: a car body 1 and wheels 4 arranged at the bottom of the car body 1; the car body 1 is rotatably connected to the upper flatbed 2 through a connecting shaft 7; the connecting shaft 7 includes an upper connecting shaft 71 and a lower connecting shaft 72, the upper connecting shaft 71 is connected to the upper flatbed 2, the lower connecting shaft 72 is connected to the car body 1, and the upper connecting shaft 71 is rotatably connected to the lower connecting shaft 72; the car body 1 is provided with a connecting column 8, and the connecting column 8 abuts against the upper flatbed 2.
[0027] Among them, Figure 3 As shown, the vehicle body 1 and the upper flat plate 2 are rectangular structures, and the vehicle body 1 and the upper flat plate 2 are connected together by the connecting shaft 7. Since the connecting shaft 7 is divided into the upper connecting shaft 71 and the lower connecting shaft 72, and the upper connecting shaft 71 and the lower connecting shaft 72 are rotatably connected, the upper flat plate 2 can be rotated. When the underground rotatable flatbed vehicle moves to a curve, if the material carried by the upper flat plate 2 is large, it is not easy to pass through the curve. By rotating the upper flat plate 2, the angle between the upper flat plate 2 and the vehicle body 1 can be adjusted, so that the underground rotatable flatbed vehicle can pass through the curve more easily, thereby improving the transportation efficiency of the underground rotatable flatbed vehicle.
[0028] At the same time, the connecting column 8 is provided on the vehicle body 1 , and the connecting column 8 can provide support for the upper plate 2 , so that when more materials are placed on the upper plate 2 , the upper plate 2 is not easily deformed.
[0029] In some embodiments, the rotation angle range of the upper connecting shaft 71 and the lower connecting shaft 72 is 0-360 degrees. The upper connecting shaft 71 is sleeved with the lower connecting shaft 72, and the upper connecting shaft 71 and the lower connecting shaft 72 are coaxial, that is, the upper connecting shaft 71 can rotate, and the rotation angle range is 0-360 degrees, so that the upper plate 2 can rotate freely in the horizontal direction. During the process of transporting materials by the underground rotatable flatbed vehicle, when the underground rotatable flatbed vehicle is difficult to pass through a curve, the upper plate 2 can be rotated to change the position of the materials on the upper plate 2 to facilitate passing through the curve.
[0030] In some embodiments, a fixing pin 6 is further included, and the connecting column 8 is a hollow cylinder; a through hole is provided at the joint between the upper plate 2 and the connecting column 8, and the fixing pin 6 passes through the through hole to connect with the connecting column 8.
[0031] Among them, the fixing pin 6 is used to fix the upper plate 2 and the vehicle body 1 so that the upper plate 2 cannot rotate. When the upper plate 2 needs to be rotated, the fixing pin 6 can be pulled out from the through hole and then the upper plate 2 is rotated. When the upper plate 2 is rotated to the target position, the fixing pin 6 can be inserted into the through hole to fix the upper plate 2 and the vehicle body 1 together again.
[0032] In some embodiments, tie rods 9 are symmetrically provided at both ends of the upper flat plate 2, and a limit block 91 is provided at one end of the tie rod 9 away from the body 1 of the upper flat plate 2. The tie rods 9 are connected to the upper flat plate 2 by welding, and when the material carried by the upper flat plate 2 needs to be fixed, the tie rods 9 can provide a support point for the rope. The tie rods 9 can be used to fix the material on the upper flat plate 2 to prevent the material from sliding or tipping over during transportation. At the same time, the tie rods 9 can also increase the stability of the material, reduce vibration and bumps during transportation, and ensure smooth transportation. At the same time, the provision of the tie rods 9 can also enable the upper flat plate 2 to carry more cargo, and when the underground rotatable flatbed vehicle is in emergency braking or turning, the tie rods 9 can also prevent the cargo from sliding or tipping over.
[0033] A limit block 91 is provided on the side of the tether rod 9 away from the upper plate 2. The diameter of the limit block 91 is larger than the diameter of the tether rod 9. When the rope is wrapped around the tether rod 9, the limit block 91 can play a limiting role, so that the rope is not easy to fall off the tether rod 9.
[0034] In some embodiments, the upper plate 2 is disposed parallel to the vehicle body 1 and has the same shape as the vehicle body 1. The upper plate 2 is a rectangular plate made of a high-strength material with excellent compression and wear resistance. A non-slip coating on its surface can reduce the risk of materials placed on the upper plate 2 slipping during movement of the underground rotatable flatbed vehicle.
[0035] In some embodiments, as Figure 2 As shown, the underground rotatable flatbed vehicle further includes a turntable 5 and a transmission assembly, and the turntable 5 is connected to the upper connecting shaft 71 via the transmission assembly. By providing the turntable 5 and the transmission assembly, when it is difficult to push the upper plate 2, the turntable 5 can be rotated to cause the transmission assembly to drive the upper connecting shaft 71 to rotate, thereby driving the upper plate 2 to rotate, so as to facilitate the rotation of the upper plate 2. At the same time, when the turntable 5 is rotated to control the rotation of the upper plate 2, the rotation angle of the upper plate 2 can be accurately controlled according to the number of turns of the turntable 5.
[0036] When the upper plate 2 is used to carry materials, if the weight of the materials is large, the upper plate 2 is easily deformed and damaged. Therefore, in some embodiments, the upper plate 2 is provided with reinforcing ribs on the side close to the vehicle body 1. By providing reinforcing ribs on the side close to the vehicle body 1, the strength of the upper plate 2 can be improved. At the same time, the side of the upper plate 2 close to the vehicle body 1 is provided with reinforcing ribs, and the side of the upper plate 2 away from the vehicle body 1 has a flat surface, which is convenient for placing materials, so that materials can be stably placed on the upper plate 2.
[0037] It is understandable that in order to improve the overall strength of the underground rotatable flatbed vehicle, reinforcing ribs may be provided on the vehicle body 1 , the upper connecting shaft 71 and the lower connecting shaft 72 .
[0038] In some embodiments, bumpers 3 are provided at both ends of the vehicle body 1 and are fixedly connected to the vehicle body 1. The bumpers 3 are provided with connection holes, through which the bumpers 3 can be connected to a traction device, which drives the underground rotatable flatbed vehicle. Due to the narrow passages underground, the bumpers 3 are provided at both ends of the vehicle body 1 so that they can be connected to a traction device to drive the vehicle body 1 forward or backward.
[0039] In order to reduce the possibility of the bumper 3 falling off during use, the bumper 3 can be fixedly connected to the vehicle body 1. For example, the bumper 3 can be connected to the vehicle body 1 by welding, or the bumper 3 and the vehicle body 1 can be integrally formed so that there is no connection gap between the bumper 3 and the vehicle body 1, thereby increasing the connection strength between the bumper 3 and the vehicle body 1.
[0040] As can be seen from the above technical solutions, the present application provides an underground rotatable flatbed truck, comprising: a vehicle body 1 and wheels 4 arranged at the bottom of the vehicle body 1; the vehicle body 1 is rotatably connected to the upper flatbed 2 via a connecting shaft 7; the connecting shaft 7 comprises an upper connecting shaft 71 and a lower connecting shaft 72, the upper connecting shaft 71 is connected to the upper flatbed 2, the lower connecting shaft 72 is connected to the vehicle body 1, and the upper connecting shaft 71 is rotatably connected to the lower connecting shaft 72; the vehicle body 1 is provided with a connecting column 8, and the connecting column 8 abuts against the upper flatbed 2. When the upper flatbed 2 carries a heavy object and travels to a bend, the upper flatbed 2 can be rotated to adjust the angle between the upper flatbed 2 and the vehicle body 1, so that the underground rotatable flatbed truck can pass through the bend, thereby improving the transportation efficiency of the underground flatbed truck.

For those skilled in the art, any other implementation methods expanded based on the scheme of this application without expending creative work shall fall within the scope of protection of this application.
