Abstract
The utility model discloses a hydraulic leg for transportation with dumping trailers and belongs to the technical field of the hydraulic leg for the transport vehicle with dumping trailers. In order to solve the technical problems, the utility model provides the hydraulic leg for transportation with dumping trailers, which is capable of safely and quickly lifting or putting down the trailers, simple in structure, stable in performance and high in automation degree. The technical scheme is that the hydraulic leg for transportation with dumping trailers comprises a frame beam and lifting devices, wherein one lifting device is fixedly arranged at each side of the frame beam; each of the lifting devices is structured in that a leg shell is fixedly connected with the frame beam, wherein hydraulic oil cylinders are arranged inside the leg shell; a piston rod of each of the hydraulic oil cylinders extends out of the lower end of the leg shell and is fixed with a boot plate by a hinged shaft; the two hydraulic oil cylinders are connected with a control unit by pipelines; the control unit is connected with a power unit; the power unit is connected with a battery main switch by an electric wire; and the operation of the control unit is controlled by an electrical control box. The hydraulic leg disclosed by the utility model is mainly used for a transport vehicle with dumping trailers.
Description
Technical field
The utility model is a kind of hangs transport trolley hydraulic ram technical field used be used to getting rid of the hydraulic ram of hanging transportation, belong to get rid of.
Background technology
Getting rid of the extension transportation is a kind of advanced person's road freight logistics mode, is developed country and the regional extensively main flow transportation modes of employing such as present America and Europe in the world.Getting rid of the extension transportation can be according to the requirement of transportation logistics, tractor truck gets rid of next trailer handling goods a station, continue transporting cargo to another station and hang up another trailer, a tractor truck can be joined three trailers, is the effective means that improves transportation and logistic efficiency.
Get rid of to hang and transport the great attention that this mode has caused country.At present, China gets rid of and hangs associated machines development hysteresis supporting in transport field, has had a strong impact on China and has got rid of the development of hanging transportation.Such as getting rid of at trailer when hanging, also holding up with the manual operation jack, efficient is low, and labour intensity is high, and potential safety hazard is large, is seriously restricting to get rid of the development of hanging transportation.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is to provide a kind ofly can be lifted trailer or put down quickly and safely be used to getting rid of the hydraulic ram of hanging transportation, and simple in structure, stable performance, degree of automation are high.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of be used to getting rid of the hydraulic ram of hanging transportation, comprise chassis frame and lifting device, the both sides of chassis frame are installed with respectively a lifting device, the structure of described lifting device is: the supporting leg housing is captiveed joint with chassis frame, the supporting leg enclosure interior is equipped with hydraulic ram, and the piston rod of hydraulic ram stretches out supporting leg housing lower end and is fixed with the boots plate by hinge;
Two hydraulic rams all are connected with control unit by pipeline, and control unit is connected with power unit, and power unit is connected with battery isolator control by electric wire, and the operation of control unit is controlled by electric control box.
The lower end of described hydraulic ram is provided with latching device.
the utility model compares with prior art the beneficial effect that has: the utility model power-on main supply switch is powered to power unit, power unit is to flow to control unit after hydraulic energy with electric energy conversion, control unit flows to hydraulic ram forward or backwards with a certain amount of hydraulic oil after receiving the signal that electric control box sends, thereby making hydraulic energy transfer is mechanical energy, realize fast and safely lifting or putting down the function of trailer, simple in structure, stable performance, degree of automation is high, High power output, convenient operation is safeguarded, increased substantially and got rid of extension efficient, reduced labour intensity, ensured labor safety.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is chassis frame, and 2 is the supporting leg housing, and 3 is hydraulic ram, and 4 is the boots plate, and 5 is pipeline, and 6 is control unit, and 7 is power unit, and 8 is electric wire, and 9 is battery isolator control, and 10 is electric control box, and 11 is latching device.
The specific embodiment
As shown in Figure 1, the utility model is a kind of be used to getting rid of the hydraulic ram of hanging transportation, comprise chassis frame 1 and lifting device, the both sides of chassis frame 1 are installed with respectively a lifting device, the structure of described lifting device is: supporting leg housing 2 is captiveed joint with chassis frame 1, supporting leg housing 2 inside are equipped with hydraulic ram 3, and the piston rod of hydraulic ram 3 stretches out supporting leg housing 2 lower ends and is fixed with boots plate 4 by hinge;
Two hydraulic rams 3 all are connected with control unit 6 by pipeline 5, and control unit 6 is connected with power unit 7, and power unit 7 is connected with battery isolator control 9 by electric wire 8, and the operation of control unit 6 is controlled by electric control box 10.
The lower end of described hydraulic ram 3 is provided with latching device 11.
Hydraulic valve and valve piece are installed in the control unit 6 in the utility model, input a certain amount of hydraulic oil according to the instruction that electric control box 10 is given in two hydraulic rams 3, make the hoisting force of hydraulic ram 3 and lifting speed adjustable.
Working process
when the tractor truck drawbar trailer arrives shipping station needs " getting rid of ", power-on main supply switch 9, start power unit 7, power unit 7 is hydraulic oil to be offered control unit 6 after hydraulic energy with electric energy conversion, the instruction that control unit 6 sends according to electric control box 10, a certain amount of hydraulic oil is synchronously squeezed in two hydraulic rams 3, latching device 11 unclamps simultaneously, hydraulic ram 3 piston rods stretch out slowly, boots plate 4 is supported in ground, trailer is held up, latching device 11 auto locks make the utility model stably hold trailer after all orders that execute electric control box 10, then the PTO Power Take Off main supply switch 9, open connecting device, tractor truck is left, complete the action of " getting rid of ",
when needing " extension ", tractor truck puts in place, power-on main supply switch 9, start power unit 7, power unit 7 is hydraulic oil to be offered control unit 6 after hydraulic energy with electric energy conversion, the instruction that control unit 6 sends according to electric control box 10, a certain amount of hydraulic oil reverse sync is squeezed in two hydraulic rams 3, latching device 11 unclamps, the piston rod of hydraulic ram 3 is retracted slowly, and drive boots plate 4 is regained, trailer falls and is placed in the relevant position of tractor truck, latching device 11 auto locks after all orders that execute electric control box 10, last PTO Power Take Off main supply switch 9, complete the action of " extension ",
So far, a whole extension program of getting rid of is completed.
