Description

Traction device and port tractor

Technical Field

The invention relates to the technical field of engineering machinery, in particular to a traction device and a port tractor.

Background

The traction device adopted by the tractor widely applied in the current road transportation industry has a certain applicability and practicality in the common road transportation scene, but has some limitations in design. Mainstream highway traction devices tend to balance safety and economy during highway driving when designed, and therefore generally have relatively limited load carrying capacity, and the majority of the fifth wheel mounting locations on such tractors are located above the frame airfoils, which results in a relatively high overall height of the traction device.

However, in a port operating environment, the need for a tractor and its traction device presents distinct features. The harbour hauling equipment needs to handle the loading and unloading and transporting tasks of heavy containers, large cargoes and various engineering equipment frequently, which puts higher standards on the carrying capacity of the hauling device. At the same time, the design of the fifth wheel lift is particularly critical in view of the special requirements of port operating space and the requirements for efficiency improvement. The fifth wheel of port tractors generally requires a lower ground clearance than highway tractors to facilitate quick and safe docking with various types of low chassis trailers, while also facilitating flexible operation in confined or confined spaces.

In the towing operation of a towing installation, the fifth wheel is used for direct connection with various vehicles or goods to be towed, which are of different volumes and heights, for example, highway tractors and port tractors have different requirements for the fifth wheel, the fifth wheel of the highway tractor has a higher ground clearance, while the port tractor has a fifth wheel with a higher bearing capacity, and the fifth wheel has a lower ground clearance.

In the above embodiment of the present invention, the supporting beam assembly 2 not only plays a role of connecting the frame with the fifth wheel assembly 1 and supporting the fifth wheel assembly 1, ensures stable connection between the fifth wheel assembly 1 and the frame, and helps to reduce vibration and wobble of the fifth wheel assembly 1 and improve stability of the towing process; the supporting beam assembly 2 can also enable the height of the traction seat assembly 1 relative to the frame to be adjustable, so that the traction seat assembly 1 can adapt to the connection requirements of vehicles or cargoes to be towed with various volumes and heights by adjusting the height of the traction seat assembly 1 relative to the frame, the flexibility and the adaptability of the traction device are improved, and the traction device can be used for highway traction working conditions and port traction working conditions, so that the working requirements under different environments are met.

Referring to fig. 2, in some embodiments, the support beam assembly 2 includes a first support beam 21 and two second support beams 22, the first support beam 21 is connected between the two second support beams 22, the fifth wheel assembly 1 is mounted on the first support beam 21, and a connection position of the first support beam 21 with respect to the second support beam 22 is adjustable in a vertical direction.

Through setting up the hookup location adjustable of first supporting beam 21 for second supporting beam 22, then through adjusting the hookup location of first supporting beam 21, can adjust the height of traction seat assembly 1 for the frame fast, switch over the operation position of traction seat assembly 1, satisfy the operation demand that traction height also changes when the operating mode changes.

Among them, the connection manner between the first support beam 21 and the second support beam 22 is variously selected.

In some embodiments, the second support beam 22 is provided with a plurality of connection parts arranged in the vertical direction, and the first support beam 21 is connected to the second support beam 22 through the connection parts.

Specifically, the setting mode of the connecting part is selected according to actual needs. For example, mounting holes having different heights may be provided on the second support beam 22 in the vertical direction, and the mounting height of the first support beam 21 may be adjusted by changing the mounting holes connected to the first support beam 21; or, a clamping groove extending along the vertical direction may be further disposed on the second supporting beam 22, and a limiting structure is disposed on the clamping groove, so that the first supporting beam 21 is pushed and pulled along the clamping groove to stop at a suitable height position, and the position of the first supporting beam 21 is fixed by the limiting structure, so that the installation height of the first supporting beam 21 can be adjusted.

In other embodiments where the working environment of the traction device has been determined, in order to increase the overall strength of the support beam assembly 2, the first support beam 21 may be welded between the two second support beams 22 after determining the relative position of the first support beam 21 with respect to the second support beams 22, so as to ensure the structural strength of the support beam assembly 2.
