[0003] This utility model relates to the technical field of chassis structure of large transport vehicles, and particularly to a chassis reinforcement structure. Background Technology

[0004] Currently, the frame structure of large transport vehicles (such as trains and trucks) is usually composed of multiple transverse beams spanning between symmetrical C-shaped steel sections. The cargo bed is then installed on the frame, which is sufficient for freight transport operations.

[0005] However, C-shaped steel is prone to deformation and breakage in the center due to load-bearing. How to solve the above problems is a problem that needs to be actively addressed by those skilled in the art. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model proposes a frame reinforcement structure to solve the above problems.

[0007] This application proposes a frame reinforcement structure, including a frame, which is an H-shaped steel structure composed of symmetrical C-shaped steel and multiple transverse beams arranged between the C-shaped steel. The characteristic feature is that a Z-shaped steel and an inverted L-shaped steel are combined on the side of the C-shaped steel opposite to the open side. The top of the Z-shaped steel is at the same height as the top of the C-shaped steel, the vertical surface of the Z-shaped steel is attached to the outside of the vertical wall of the C-shaped steel, and the bottom of the Z-shaped steel abuts against the bottom of the C-shaped steel. The top surface of the L-shaped steel overlaps below the top of the Z-shaped steel, and the vertical surface of the L-shaped steel is connected to the vertical surface of the Z-shaped steel. A reinforcing C-shaped steel is provided inside the opening of the C-shaped steel, and multiple bolt holes and multiple connecting bolts are also included. The bolt holes penetrate the reinforcing C-shaped steel from one end of the L-shaped steel, and the connecting bolts are inserted into the corresponding bolt holes.

[0008] This application provides a Z-shaped steel and an L-shaped steel on the outside of the C-shaped steel of the frame, and a reinforcing C-shaped steel is joined on the inside of the C-shaped steel. After the above structural reinforcement, the frame can increase the static load and dynamic load, and avoid deformation, breakage and other situations when the frame bears the load.

[0009] The outer side and bottom of the C-shaped steel are reinforced with L-shaped and Z-shaped steel, while the inside of the C-shaped steel is reinforced with additional C-shaped steel to increase strength and toughness, thereby increasing the load-bearing capacity and structural strength of the frame.

[0010] Preferably, a reinforcing plate is provided at the top of the C-shaped steel and the top of the Z-shaped steel.

[0011] Preferably, the thickness of the Z-shaped steel is 0.8cm to 2cm.

[0012] Preferably, the thickness of the L-shaped steel is 0.5cm to 1.5cm.

[0013] Preferably, the thickness of the reinforcing C-shaped steel is 0.3 to 1.2 cm.

[0014] Preferably, the connecting bolt is a bolt or rivet.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] The reinforced frame of this application has a bending moment of nearly 104 metric tons-meters and a shear strength increase of nearly 760 metric tons. The reinforced frame is able to withstand higher loads and higher dynamic loads.

[0017] With the reinforcement plate installed at the top, the bending moment of the frame is nearly 133 metric ton-meters, and the shear strength is increased by nearly 1020 metric tons, allowing the frame to be modified into equipment that needs to withstand higher loads, such as cranes and trucks.
