Abstract
The utility model discloses a hydraulic system, in particular to a waste transfer truck hydraulic system. According to the waste transfer truck hydraulic system, a travel air valve is arranged on a secondary bracket at a position close to a swing arm mechanism, a rear door is opened and is buckled by the swing arm mechanism to swing upwards, and pressure is applied to the travel air valve by the swing arm mechanism to retract the travel air valve at the time, so that full opening of the rear door is prompted, the phenomenon that a carriage is firstly lifted and then the rear door is opened caused by confused opening of the rear door and the carriage in the prior art is solved, the carriage is lifted under the condition that the rear door is not opened, and the defects of deformation and damage of the rear door caused by compression of wastes towards the rear door under the action of gravity are overcome; and the waste transfer truck hydraulic system is used for a waste transfer truck or an excavator and the like.
Description
Technical field
The utility model relates to hydraulic efficiency pressure system, relates in particular to a kind ofly for waste-skip, and tip lorry etc. need to be opened the back door the improved waste transportation truck system of realizing toppling over object.
Background technology
At present, it is damaged that tip lorry and waste-skip etc. all exists the back door to open the period improper back door that causes, the defective that object is difficult to properly topple over, take the rubbish rubbish van as example:
The rubbish rubbish van is at garbage compression station, will the good rubbish of compression, pack casing into from vehicle rear in.Vehicle Driving Cycle is at first opened the back door behind the garbage disposal plant, then the lifting casing is realized the landing of rubbish.The back door opening and closing of rubbish rubbish van are to adopt the oil cylinder pushing oscillating arm mechanisms that is installed in the railway carriage side, make the back door around upwards upset of hinged-support.Shown in Fig. 1-2, subframe is installed above chassis frame, the elevating ram lower bearing pin is installed in the middle part of subframe, and the upper pin of elevating ram is installed on the underframe at railway carriage middle part.By the action of elevating ram, railway carriage rotates around main free bearing, realizes dumping of railway carriage.
The hydraulic efficiency pressure system of current rubbish rubbish van control railway carriage lifting and rear door switch mainly is to adopt two groups of Pneumatic valve control pore multiway valve, with the action of control elevating ram and back door oil cylinder.Hydraulic system principle figure as shown in Figure 3.
The sequence of operation of vehicle design is: and the back door opens-and body lifting-railway carriage falls-and the back door is closed.Because Pneumatic valve is two groups, respectively door switch and railway carriage lifting after the control, therefore tend to occur maloperation, the phenomenon that causes the lifting of railway carriage elder generation then to be opened behind the door, in the situation about not opening at the back door like this, body lifting causes rubbish to press down to the back door at action of gravitation, the back door distortion occurs and damages phenomenon.
The utility model content
Defects based on the prior art existence, the purpose of this utility model is to provide a kind of improved waste transportation vehicle hydraulic system, by improving hydraulic efficiency pressure system, makes each sequence of operation of railway carriage meet designing requirement, prevent from damaging because maloperation makes the back door, realize the essential safety of vehicle.
A kind of improved waste transportation truck system that the utility model provides comprises swing arm structure, back door, elevating ram and underframe; Swing arm structure is connected with assistant support by hinged-support, and elevating ram is connected with assistant support and underframe by bearing pin, and underframe is positioned on the assistant support; Wherein, assistant support is provided with the flexible air valve of opening fully by indentation prompting back door.
The first preferred improved waste transportation truck system that the utility model provides, flexible air valve is the stroke air valve, the stroke air valve comprises expansion link, valve head and trace, and valve head is positioned at an end of expansion link, and the other end is fixed on the position of close swing arm structure on the assistant support by flexible connection.
The second preferred improved waste transportation truck system that the utility model provides is flexibly connected as the mode by bolt and connects.
Hydraulic system principle figure is as shown in Figure 5: usually control the air inlet source of the Pneumatic valve of elevating ram, and the same with the air inlet source of the Pneumatic valve of control back door oil cylinder, come from air receiver.The air inlet source of control elevating ram, from the stroke air valve, the air inlet source of stroke air valve is from air receiver.The stroke air valve is open in usual, only has after the stroke valve rod is promoted indentation by oscillating arm mechanisms, and its inlet, outlet eloquence is connected.Namely only have first fully after the open back door, Pneumatic valve and the elevating ram of control elevating ram could be worked, railway carriage ability lifting or fall, thereby the function that this has just realized preventing maloperation, accident appears in the lifting railway carriage in the situation about not opening at the back door.
The utility model improves by the hydraulic efficiency pressure system to the rubbish rubbish van, increase the stroke air valve, thereby accident appears in the lifting railway carriage in the situation that prevents from not opening at the back door, has avoided having realized the essential safety of vehicle because maloperation causes vehicle generation safety misadventure from design.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Embodiment 1
The improved waste transportation truck system of present embodiment shown in Fig. 1-2, comprises chassis 1, compartment 2, swing arm structure 4, back door 5, elevating ram 7 and underframe 8 take the rubbish rubbish van as example; Chassis 1 is connected with assistant support 9 by main free bearing 6, compartment 2 is positioned at the periphery of chassis 2 vehicle seats, swing arm structure 4 is connected with assistant support 9 by hinged-support 3, elevating ram 7 is connected with assistant support 9 and underframe 8 by bearing pin, and underframe 8 is positioned on the assistant support 9, back door 5 is the detachable end that is positioned at swing arm structure 4, and swing arm structure 4 can block back door 5 when swinging to its top together, at the beginning the rubbish delivery port; Assistant support 9 is provided with the flexible air valve of opening fully by indentation prompting back door 5.
