Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic trailers, and particularly to a hydraulic trailer for transporting large-sized goods. Background Art

[0002] Hydraulic trailers are key equipment in large-sized goods transportation. A hydraulic trailer includes a trailer body and a hydraulic system arranged on the trailer body. The lifting operation and steering operation of the trailer body are realized through the hydraulic system to improve the passing performance of the hydraulic trailer on the transportation road. Among them, the hydraulic system is composed of a diesel engine, a hydraulic oil pump, an operation box, a hydraulic oil tank, and each hydraulic cylinder serving as a hydraulic actuator.

[0003] In the existing hydraulic trailer, the diesel engine and the hydraulic oil pump follow as a whole, and the hydraulic oil tank is integrated into the corresponding girder of the hydraulic trailer, as shown in Figure 1 、 Figure 2 and Figure 3 . Among them, Figure 1 shows a structural schematic diagram of a full-trailer type hydraulic trailer, Figure 2 shows a structural schematic diagram of a semi-trailer type hydraulic trailer, Figure 3 shows a cross-sectional structure of the trailer body girder integrated with a hydraulic oil tank. For the full-trailer type hydraulic trailer as shown in Figure 1 , the diesel engine and the hydraulic oil pump can be arranged at the front end of the trailer body, close to the drawbar, according to the structure of the large-sized goods being transported, or can be arranged at the counterweight box of the tractor. For the semi-trailer type hydraulic trailer as shown in Figure 2 , the diesel engine and the hydraulic oil pump are arranged at the power gooseneck of the trailer body. As shown in Figure 3 , the girder 2 integrated with the hydraulic oil tank mainly consists of a panel 3, a wall panel, an inclined support beam 5, a main web 4, etc. to form a hollow structure, and the internal space is used as a box for storing hydraulic oil.

[0004] However, due to the formed structure of the existing hydraulic trailer, the hydraulic oil tank cannot move along with the diesel engine and the hydraulic oil pump, and long hydraulic oil pipes are required for connection. The hydraulic oil pump has a long idling phenomenon at the initial stage of doing work and is prone to burning the pump. At the same time, since the girder of the trailer body is the main load-bearing structure of the trailer and needs to bear the support and load-bearing tasks, its arrangement position on the trailer body is specific and the space is limited, resulting in a limited volume of the hydraulic oil tank integrated into the girder and the hydraulic oil tank integrated into the girder being not easy to open, thus increasing the operation difficulty of cleaning and replacing the hydraulic oil (since the hydraulic oil in service for a long time will generate impurities and sediments, which will directly affect the operation stability and safety of the hydraulic system, so it needs to be cleaned and replaced in time). Summary of the Utility Model

[0005] The technical objective of the present utility model is to provide a hydraulic trailer for transporting large-sized goods, which is beneficial to improving the operation stability and safety of the hydraulic system and facilitating the cleaning and replacement operation of hydraulic oil, in view of the particularity of the above-mentioned hydraulic trailer and the deficiencies of the prior art.
