Referring to fig. 1 in combination with fig. 2, a vehicle frame of the transportation vehicle provided by the embodiment of the present invention is mainly suitable for transporting round coiled materials such as coiled steel and coiled aluminum, and the vehicle frame of the transportation vehicle can also be used as a semitrailer frame, and the vehicle frame of the transportation vehicle mainly includes a longitudinal beam 1, a cross beam 2 and a supporting device.

The longitudinal beams 1 are arranged in two numbers, the longitudinal beams 1 extend in the front-back direction, and the two longitudinal beams 1 are arranged in a left-right parallel interval mode.

The crossbeam 2 sets up perpendicularly between two longerons 1, and the both ends of crossbeam 2 are respectively with a longeron 1 fixed connection.

In some embodiments, the top surface of the cross beam 2 is flush with the top surface of the longitudinal beam 1, so as to form a relatively flat supporting surface on the top surfaces of the cross beam 2 and the longitudinal beam 1, so as to place the articles to be transported.

The cross beams 2 are provided in plurality, and the cross beams 2 are arranged at intervals in the front-back direction along the extending direction of the longitudinal beam 1. The plurality of cross beams 2 connect the longitudinal beams 1, so that the stability of the overall structure of the frame can be enhanced.

Referring to fig. 1 and 2, a supporting device is arranged on the longitudinal beam 1, and the supporting device is used for placing and fixing the circular coiled material.

The supporting device is arranged in the interval between two adjacent cross beams 2; two ends of the supporting device are respectively connected and fixed with a longitudinal beam 1; the support means is recessed downwardly with a support groove 32.

In some embodiments, the supporting device may include two lateral supports 31, the two lateral supports 31 being spaced back and forth along the extending direction of the longitudinal beam 1; the transverse supporting member 31 is vertically arranged between the two longitudinal beams 1, and two ends of the transverse supporting member 31 are respectively connected and fixed with one longitudinal beam 1.

Referring to fig. 4 in conjunction with fig. 1 and 2, the top surface of the transverse supporting member 31 is recessed downward to form a supporting groove 32. The supporting groove 32 is used for supporting a circular coil such as a coil steel, an aluminum coil, etc., and the coil steel can be stably placed on the supporting groove 32 which is concavely arranged.

Referring to fig. 1 and 2, in the supporting device, two transverse supporting members 31 are used as a group to stably support the front end and the rear end of the coil steel. The number of the transverse supporting pieces 31 can be one, or a plurality of the transverse supporting pieces 31 can be arranged, and the plurality of the transverse supporting pieces 31 are arranged at intervals in the front and back direction and support the corresponding coil steel together, so that the support stability of the coil steel is further improved.

The height of the bottom surface of the support groove 32 is lower than that of the top surface of the cross beam 2. Therefore, when the coil steel is placed on the support groove 32, the center of the coil steel can be lowered to improve the safety and stability of the transportation of the coil steel.

The transverse supports 31 and the transverse beams 2 are arranged at intervals on the longitudinal beams 1. The transverse support member 31 and the transverse beam 2 can be connected and fixed with the longitudinal beams 1 on the left and right sides, so that the transverse support member 31 has the function of the transverse beam 2 and can be used as the transverse beam 2. An increase in the number of transverse supports 31 may correspond to a decrease in the number of cross members 2 in the frame. In addition, it should be noted that the supporting groove 32 is formed on the top surface of the cross beam 2 in a downward concave manner, and can be equivalent to a transverse supporting member 31.

Still referring to fig. 1 and 2, in some embodiments, a cross beam 2 is provided in spaced relation to each of the front and rear sides of each coil support. Because the top surface of the cross beam 2 is higher than the bottom surface of the supporting groove 32, when the coil steel is placed on the supporting groove 32 of the supporting device, the cross beam 2 at the front side and the rear side of the supporting device can limit the coil steel on the supporting groove 32 in the supporting device in the front and back directions, and the coil steel is prevented from separating from the supporting groove 32 on the supporting device and even from the frame when the vehicle is accelerated or decelerated suddenly, thereby effectively improving and ensuring the safety of coil steel transportation.

In some embodiments, a stop 4 is also provided on the frame corresponding to the front side of each coil support. The stop member 4 is correspondingly arranged on the cross beam 2 at the front side of the supporting device, and the stop member 4 protrudes from the top surface of the cross beam 2 and extends upwards. The stop part 4 can further improve the limiting effect of the frame on the coil steel on the supporting device, namely, the stop area of the frame and the coil steel is improved by utilizing the stop part 4. When the vehicle brakes suddenly, the stop piece 4 can effectively prevent the coil steel from jumping out forwards and flying to the front side of the vehicle to cause safety accidents due to the fact that the mass and inertia of the coil steel are large; therefore, the risk can be further reduced, and the safety of the transportation of the coil steel is improved.

In some embodiments, the stop 4 can be provided in plurality, side by side on the same cross beam 2. The stop members 4 on the same beam 2 can be connected by a fixing rod 41 to enhance the mechanical strength and stop effect of the stop members 4.

The two support slopes 321 form a V-like space between them, which is the support groove 32. When the coil steel is placed on the supporting groove 32, the circumferential wall of the circular coil steel will contact with the supporting slopes 321, and the two supporting slopes 321 cooperate to be stably clamped between the two supporting slopes 321. Meanwhile, for the coil steels with different diameters, the peripheral wall of the coil steel can contact with the supporting inclined surface 321, so the supporting groove 32 with the shape can be suitable for supporting and clamping the round coil steels with different diameters.

Referring still to fig. 4 to 6, in some embodiments, a supporting bottom 322 for engaging the bottom of the two supporting slopes 321 is further disposed on the transverse supporting member 31 between the bottom ends of the two supporting slopes 321. A smooth transition structure may be adopted between the supporting bottom 322 and the supporting inclined plane 321, the supporting bottom 322 and the supporting inclined planes 321 on both sides form the supporting groove 32, and the height of the supporting bottom 322 is lower than that of the top surface of the beam 2. The arrangement of the supporting bottom surface 322 can make the structure of the transverse supporting member 31 more stable, and the supporting bottom surface 322 can also be used for supporting the coil steel, thereby improving the stability of the coil steel support.
