Embodiment

[0030] The invention provides a vehicle frame, such as Figure 1 to Figure 3 As shown, the vehicle frame body and the end support frame 2 are included, and the vehicle frame body includes a frame structure formed by interconnecting the bottom frame, the column and the top frame. Specifically, the underframe includes a main beam 11 , a secondary beam 12 and a bottom plate 13 , and the main beam 11 is arranged at the middle part of the bottom of the vehicle frame body along the length direction of the vehicle frame body. A plurality of secondary beams 12 are respectively connected to the main beam 11 along the width direction of the frame body by welding or bolting, and the multiple secondary beams 12 are arranged at intervals along the length direction of the main beam 11 . After the main beam 11 and the secondary beam 12 are connected, the upper surfaces are flush, and the bottom plate 13 is connected to the upper surfaces of the main beam 11 and the secondary beam 12 by weldi...

Abstract

The invention discloses a vehicle frame, relates to the technical field of underground pipeline transportation, and solves the technical problem that under the condition of the same pipeline section size, an existing vehicle influences the cargo transportation efficiency due to small volume. The vehicle frame comprises a vehicle frame body and end bearing frames, the two end bearing frames are arranged at the two ends of the vehicle frame body in the length direction of the vehicle frame body respectively and used for being connected with a bogie, the bottom face of the vehicle frame body is sunken in the height direction of the vehicle frame body, and the bottom faces of the end bearing frames are higher than the bottom face of the vehicle frame body. The height of the bottom face of theend bearing frame is designed to be larger than that of the bottom face of the frame body, that is, the frame body is designed to be of a downwards-concave structure relative to the end bearing framesat the two ends, and after the end bearing frames are connected to the bogie, under the conditions of the same pipeline section size and the same vehicle length, the volume of the vehicle can be increased by 30% or above, so that the transportation efficiency of the vehicle is greatly improved.

Description

technical field [0001] The invention relates to the technical field of underground pipeline transportation, in particular to a vehicle frame. Background technique [0002] With the increasing development of urban underground logistics system, the design of underground pipeline transportation vehicles has gradually become an important research topic. At present, the size of the cross-sectional area of ​​the pipeline determines the cost of pipeline construction and the efficiency of cargo transportation. The larger the cross-sectional area of ​​the pipeline, the higher the height of the corresponding vehicle can be designed, which can increase the volume of the vehicle and improve the cargo transport efficiency. delivery efficiency. However, the corresponding pipeline construction cost has also increased significantly. In the prior art, under the condition of the same cross-sectional size of the pipeline, the volume of the vehicle is relatively small, resulting in low effici...
