Description
Technical field
The utility model relates to the torque arm device in the roll off skip loader, is specifically related to a kind of piping layout system of torque arm device hydraulic directional control valve.
Background technology
At present, the piping layout of torque arm device hydraulic efficiency pressure system on the market uses flexible pipe more, no matter pipeline length uses flexible pipe to arrange mostly, and level is clearly demarcated inadequately, the potential safety hazard that exists the alternating expression layout to bring, particularly long along the pipeline of subframe trend, if it is use flexible pipe, sagging in order to prevent intermediate conduit, several roads pipeline is bundled into a branch of fixing, do not have level, attractive in appearance inadequately, which bar pipeline can not tell fast specifically is; What the hand change over valve place adopted is that vertical mode is arranged, joystick is positioned at the top, and manual operation is not easily, and vertical arrangement is unfavorable for that flexible pipe bends and moves towards towards a direction jointly herein, and the pipeline that comes out of cloth seems very in disorder like this.
The utility model content
The utility model has overcome the deficiency that prior art exists, and provides that a kind of commonality is good, the piping layout system of neat appearance, the torque arm device hydraulic directional control valve being convenient to keep in repair.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of piping layout system of torque arm device hydraulic directional control valve, comprise subframe and hand change over valve, the subframe top is provided with the valve stay bearing plate, the bottom of subframe is provided with at least two hard tubes, be vertically installed with the valve adapter plate on the described valve stay bearing plate, described hand change over valve is arranged on the valve adapter plate, hand change over valve is provided with at least one joystick, described joystick is positioned at a side of valve adapter plate, each joystick is all controlled the switching of two corresponding on hand change over valve hydraulic fluid ports, and two described hydraulic fluid ports are all by two corresponding connections with hard tube of flexible pipe.
Described hand change over valve is provided with four joysticks, and four described joysticks all be arranged in parallel, and wherein two hydraulic fluid ports controlling separately of three described joysticks are all by two corresponding connections with hard tube of flexible pipe.
Be provided with the valve brace panel between described valve adapter plate and the valve stay bearing plate.
Described hard tube is fixed on described subframe bottom by pipe clip, and described flexible pipe is connected by adaptor union with hard tube.
The utility model compared with prior art has following beneficial effect.
What 1, the pipeline at the utility model hand change over valve place adopted is the flexible pipe that caliber is identical, length is consistent, and commonality is very good.
2, the utility model hand change over valve adopts landscape mode to arrange, the layout of flexible pipe energy orderliness, joystick is positioned at the side, manual operation is more convenient, comfortable, hydraulic valve operating label, warning label are affixed on the valve adapter plate, and the position is obvious, is convenient to observe, article eight, flexible pipe can bend neat appearance towards a direction jointly.
3, the utility model adopts hard tube along the pipeline of subframe trend, endurance, and flow passage resistance force of waterproof is little, and steel pipe can be arranged to horizontal flat vertical comb, and each road pipeline is well arranged, neat and consistent, convenient fixing, not fragile; The utility model is fixed on the subframe by pipe clip along the hard tube of subframe trend, and the installation of pipe clip, dismounting can realize by the bolt of twisting on the geometrical clamp, uses, maintenance is very convenient, the efficient height.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is that subframe, 2 is that hand change over valve, 3 is that valve stay bearing plate, 4 is that valve adapter plate, 5 is that joystick, 6 is that flexible pipe, 7 is that hard tube, 8 is that valve brace panel, 9 is that pipe clip, 10 is adaptor union.
The specific embodiment
As shown in Figure 1, the piping layout system of a kind of torque arm device of the utility model hydraulic directional control valve, comprise subframe 1 and hand change over valve 2, subframe 1 top is provided with valve stay bearing plate 3, the bottom of subframe 1 is provided with at least two hard tubes 7, be vertically installed with valve adapter plate 4 on the described valve stay bearing plate 3, described hand change over valve 2 is arranged on the valve adapter plate 4, hand change over valve 2 is provided with at least one joystick 5, described joystick 5 is positioned at a side of valve adapter plate 4, each joystick 5 is all controlled the switching of two corresponding on the hand change over valve 2 hydraulic fluid ports, and two described hydraulic fluid ports are all by two flexible pipes 6 and hard tube 7 corresponding connections.
Described hand change over valve 2 is provided with 5, four described joysticks 5 of four joysticks and all be arranged in parallel, and wherein two hydraulic fluid ports controlling separately of three described joysticks 5 are all by two flexible pipes 6 and hard tube 7 corresponding connections.
Be provided with valve brace panel 8 between described valve adapter plate 4 and the valve stay bearing plate 3.
Described hard tube 7 is fixed on described subframe 1 bottom by pipe clip 9, and described flexible pipe 6 is connected by adaptor union 10 with hard tube 7.
It is clearly demarcated inadequately that the utility model has solved in the existing piping layout system soft or hard pipe level, avoided flexible pipe from the beginning to go to the single arrangement of tail, the utility model moves towards the longer pipe road along subframe 1 and adopts hard tube 7, hard tube 7 is well arranged by pipe clip 9, neat being fixed on the subframe 1 attractive in appearance, hand change over valve 2 adopts landscape mode to arrange, joystick 5 is positioned at the side, manual operation is more comfortable, the hydraulic valve operating label is installed on the valve adapter plate 4 at hand change over valve 2 places with the warning label, the position is obvious, it is convenient to observe, the pipeline that hand change over valve 2 connects adopts caliber identical, the length unanimity can be general flexible pipe 6, owing to be that landscape mode is arranged, flexible pipe 6 easier orderliness are arranged herein, can bend towards a direction jointly, pass through from subframe 1 front end, be connected with described hard tube 7 by adaptor union 10.
