[0024] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0025] An underground flatbed truck is a type of equipment specially used for transportation in underground mines and underground tunnels, and is a rail-type transport vehicle. Among them, underground flatbed trucks are mainly used to carry a large amount 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. By loading these materials on the flatbed truck, they can be quickly and safely transported from the underground or underground tunnel to the designated location, thereby improving production efficiency and work benefits. When an underground flatbed truck transports heavy materials to an intersection or an intersection with a large curvature, the underground flatbed truck is not easy 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 make the flatbed truck pass through the intersection or the intersection with a large curvature, which is prone to danger, 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 A front view of an underground rotatable flatbed vehicle provided in an embodiment of the present application, Figure 2 This is a top view of an underground rotatable flatbed vehicle provided in an embodiment of the present application. The embodiment of the present application provides an underground rotatable flatbed vehicle, 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.

[0027] Among them, Figure 3 As shown, the vehicle body 1 and the upper plate 2 are rectangular structures, and the vehicle body 1 and the upper 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 plate 2 can be rotated. When the underground rotatable flatbed vehicle moves to a curve, if the material carried by the upper plate 2 is large, it is not easy to pass through the curve. By rotating the upper plate 2, the angle between the upper 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 arranged 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°. 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°, so that the upper flat plate 2 can rotate freely in the horizontal direction. In 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 flat plate 2 can be rotated to change the position of the material on the upper flat plate 2 to facilitate passing through the curve.

[0030] In some embodiments, a fixing pin 6 is also 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 be connected to 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 rod 9 is 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 rod 9 can provide a support point for the rope. The tie rod 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 rod 9 can also increase the stability of the material, reduce vibration and bumps during transportation, and ensure smooth transportation. At the same time, the setting of the tie rod 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 rod 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 wound 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 arranged parallel to the vehicle body 1, and the upper plate 2 has the same shape as the vehicle body 1. The upper plate 2 is a rectangular plate, and the upper plate 2 is made of high-strength material, and has good compression resistance and wear resistance. A layer of anti-skid material is coated on its surface, so that when the material is placed on the upper plate 2, the material can be reduced from sliding during the movement of the underground rotatable flatbed vehicle.

[0035] In some embodiments, 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 through the transmission assembly. By setting the turntable 5 and the transmission assembly, when it is difficult to push the upper flat plate 2, the turntable 5 can be rotated to make the transmission assembly drive the upper connecting shaft 71 to rotate, and then drive the upper flat plate 2 to rotate, so as to rotate the upper flat plate 2. At the same time, when the turntable 5 is rotated to control the rotation of the upper flat plate 2, the rotation angle of the upper flat 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, when the weight of the materials is large, the upper plate 2 is easily deformed and damaged. Therefore, in some embodiments, a reinforcing rib is provided on the side of the upper plate 2 close to the vehicle body 1. The strength of the upper plate 2 can be improved by providing the reinforcing rib on the side of the upper plate 2 close to the vehicle body 1. At the same time, the reinforcing rib is provided on the side of the upper plate 2 close to the vehicle body 1, and the surface of the side of the upper plate 2 away from the vehicle body 1 is flat, which is convenient for placing materials, so that the materials can be stably placed on the upper plate 2.

[0037] It can be understood 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, the two ends of the vehicle body 1 are provided with bumpers 3, and the bumpers 3 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, and the traction device can be used to drive the underground rotatable flatbed vehicle to move. Due to the narrow underground passage, the bumpers 3 are provided at both ends of the vehicle body 1, and the traction device can be connected 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 can be integrally formed with the vehicle body 1, 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] It can be seen from the above technical scheme that the present application provides an underground rotatable flatbed vehicle, 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 as to facilitate the underground rotatable flatbed vehicle to pass through the bend, so as to improve the transportation efficiency of the underground flatbed vehicle.
