Embodiment 1

[0048] Embodiment one is basically as Figure 1 to Figure 3 As shown: this embodiment provides a dual-purpose direct-mounted container semi-trailer for roads and railways. The structure of the semi-trailer can be used as a load-bearing structure for container 12 railway transportation. When entering the railway transportation, the semi-trailer does not need to be hoisted by hoisting equipment Carry out transport on the railway special transport vehicle; The present embodiment container semi-trailer comprises vehicle frame 1, supporting device 9, side protection 10, air suspension 5, axle 4, railway operation air braking force and signal transmission device 8, rear protection 13 And road operation brake system 11 etc., wherein rear protection is the overturning structure, and it is turned down when the road is running, and it is turned up when the railway is running. Wheel axle 4, supporting device 9, side protection 10, railway operation air braking force and signal transmissi...

Embodiment 2

[0055] The second embodiment is basically the same as the first embodiment, the difference is that in order to conveniently and stably lock the front end of the container 12, this embodiment is provided with positioning bolt devices 6 on both sides of the front end beam 1.1 of the vehicle frame 1, two The left and right sides of the front end of the container 12 that the positioning bolt device 6 is correspondingly loaded into are relatively arranged, as Figure 8 to Figure 10 As shown, the positioning bolt device 6 specifically includes a positioning bolt 6.1 and a casing 6.2 sleeved on the outside of the positioning bolt 6.1. The casing 6.2 is fixedly installed on the bottom plate 1.1.1 of the front end beam 1.1, between the casing 6.2 and the positioning bolt 6.1. A steel spring 6.3 is provided, and the pre-compression force of the steel spring 6.3 always maintains the positioning bolt 6.1 on the side of the front end beam bottom plate 1.1.1 close to the bushing 6.2, and the...

Embodiment 3

[0059] The third embodiment is basically the same as the second embodiment, the difference is: please refer to Figure 11 to Figure 14 As shown, the passive lifting air suspension 5 provided in this embodiment includes a bracket 5.2 and a suspension airbag 5.3 fixed on the vehicle frame 1, and the bracket 5.2 and the suspension airbag 5.3 are respectively fixed on the vehicle on both sides of the wheel axle 4 of the vehicle body. On the frame 1, a guide arm 5.1 is also provided in this embodiment. The left end of the guide arm 5.1 is rotationally connected with the support 5.2 through a hinge 5.6. The hinge 5.6 in this embodiment is preferably a round pin, and the right end of the guide arm 5.1 is connected to the cantilever airbag through a bolt. The lower end is fixedly connected, and the wheel shaft 4 is fixed on the middle part of the guide arm 5.1 through a U-shaped bolt 5.7. The air spring in the prior art of the suspension air bag 5.3 provided in this implementation can ...

Abstract

The invention discloses a highway and railway dual-purpose direct-hanging type container semi-trailer, and relates to the technical field of vehicle manufacturing. The container semi-trailer comprisesa frame, a supporting device, a side defending device, an air suspension, an axle, a railway running air braking force and signal transmission device, a rear defending device and a highway running braking system; and the front end of the frame is provided with a semi-trailer traction pin, each of the front end and the rear end of the frame is provided with a guide connector which is in coupling with a railway special bogie, the axle is provided with the passive lifting type air suspension, a positioning bolt device is arranged at the front end of the frame, and a rotary lock device is arranged at the rear end of the frame. By implementing the technical scheme, the technical problem that an existing container semi-trailer is low in transportation economical efficiency on a highway and a railway can be effectively solved, the structure of the semi-trailer can be used as a bearing structure for railway transportation, the requirement of safe running of a vehicle on the highway or the railway is met, the useless dead weight in railway transportation is effectively reduced, the effective cargo capacity is improved, and the transportation economical efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a dual-purpose direct-mounted container semi-trailer for roads and railways. Background technique [0002] In the modern vehicle transportation system, the road and rail combined transport mode has been vigorously developed, and the vehicle equipment supporting the road and railway operation mode has also been developed rapidly, and the most widely used transport vehicles are container semi-trailers. , the road tractor is connected to the road container semi-trailer for road transportation; while for railway transportation, the container semi-trailer needs to be hoisted on the special railway transport vehicle with hoisting equipment, or the semi-trailer and tractor itself are used as For railway transportation of goods, the mode of directly driving the semi-trailer onto the railway transportation vehicle. There is also an air pressure device or a hydraulic device ...
