Square construction project.Hanging oil cylinder is the core component of quarry tipper, and it is the flexible member of connecting vehicle frame and wheel.Its work
With being vertical reaction road surface being acted on wheel（Supporting force）, longitudinal counter-force（Pull strength and brake force）With lateral reaction with
And the moment caused by these counter-forces will be delivered on vehicle frame, to ensure the normally travel of automobile.Inflatable tool is by nitrogen
It is filled with the instrument of hanging oil cylinder, be filled with how many direct performances determining hanging oil cylinder of nitrogen.Conventional inflatable tool can only be right
Single oil cylinder is inflated, and cannot realize the connection of two oily gas in the jar, lead to two in-oil cylinder air pressure after the completion of inflation
Unbalanced, affect hanging oil cylinder performance.
Content of the invention
For the deficiencies in the prior art, the purpose of the invention is to provide a kind of quarry tipper hanging oil cylinder inflator
Tool, this instrument achieves the connection of two oily gas in the jar, makes two in-oil cylinder air pressure equalisation, improves hanging oil cylinder performance,
Possess installation simple, reliability is high, save the advantages of space, good looking appearance.
For achieving the above object, the invention is realized by following technological means：
A kind of quarry tipper hanging oil cylinder inflatable tool, including nitrogen cylinder, gas-charging connection it is characterised in that：Also include
Multiple-way valve, described nitrogen cylinder is connected with multiple-way valve through aspirated switch, and described gas-charging connection is divided into the first gas-charging connection and second
Gas-charging connection, is connected with multiple-way valve respectively through the first gas-filled switching tube and the second gas-filled switching tube.
Further：
Described multiple-way valve is cross valve.
Described cross valve is also associated with pressure gauge.
Described nitrogen cylinder is connected with aspirated switch by high-pressure hose.
Described first gas-charging connection and the second gas-charging connection are filled with the first gas-filled switching tube and second by high-pressure hose respectively
Air cock connects.
It is additionally provided with nitrogen cylinder joint between nitrogen cylinder and high-pressure hose.
Described aspirated switch, the first gas-filled switching tube and the second gas-filled switching tube are ball valve.
The beneficial effect of the invention is：This instrument can achieve to nitrogen cylinder, the pressure detecting of left and right hanging oil cylinder, two
The connection of individual oil gas in the jar, makes two in-oil cylinder air pressure equalisation, improves hanging oil cylinder performance, possesses installation simply, reliable
Property high, save the advantages of space, good looking appearance.
Brief description
Fig. 1 is structure composition schematic diagram.
Specific embodiment
Below in conjunction with Figure of description, the invention is further described.
As shown in drawings, specific embodiment of the utility model, by the first gas-charging connection 101, the second gas-charging connection 102, is sent
Air cock 4, the first gas-filled switching tube 501 and the second gas-filled switching tube 502, all switch as ball valve, nitrogen cylinder joint 7, cross valve 3,
Pressure gauge 6, nitrogen cylinder 2, high-pressure hose 8 forms.During tool assemble, pressure gauge 6 is arranged on a valve port of cross valve 3, will
First gas-charging connection 101, the second gas-charging connection 102 are connected on high-pressure hose 8, and nitrogen cylinder 2 is through nitrogen cylinder joint 7 and high pressure
Flexible pipe 8 connects, then respectively by three high-pressure hoses 8 connect to three ball valves of four-way valve seat i.e. can be assembled finish, install
Fairly simple.
Aspirated switch ball valve 4, as total source of the gas, is closed two the first gas-filled switching tubes 501 and the second gas-filled switching tube 502, is opened
Ball valve 4 can record pressure in nitrogen cylinder 2 by pressure gauge 6 reading, and pressure measurement is convenient.
When needing to inflate to hanging oil cylinder, to first close ball valve 4, open two ball valve the first gas-filled switching tube 501 Hes in left and right
Second gas-filled switching tube 502, the first gas-charging connection 101, the second gas-charging connection 102 are connected to hanging oil cylinder charge valve, then open
Aspirated switch ball valve 4, so can achieve and inflates to two hanging oil cylinder simultaneously, when the piston rod extension elongation of both sides oil cylinder reaches
During to design load, stop inflation（Stop will first closing total air source ball valve aspirated switch 4 during inflation, turn off two ball valves in left and right
First gas-filled switching tube 501 and the second gas-filled switching tube 502）.Close aspirated switch 4, then open first gas-filled switching tube on the left side
501, you can the gas pressure in the hanging oil cylinder of the left side is recorded by pressure gauge reading, close first gas-filled switching tube 501 on the left side,
Open ball valve second gas-filled switching tube 502 on the right, you can the gas pressure in the hanging oil cylinder of the right is recorded by pressure gauge reading,
If gas pressure difference is in more than 0.5MPa in the oil cylinder of both sides, need the first gas-filled switching tube 501 and the second gas-filled switching tube 502
Open, now the gas in two oil cylinders starts intercommunication, during intercommunication ten minutes about, the first gas-filled switching tube 501 and second are filled
Air cock 502 is closed, and then pulls down inflatable tool, and whole gas replenishment process finishes.
Ultimate principle, principal character and the advantage of the invention have been shown and described above.The technical staff of the industry
Simply explanation the design it should be appreciated that the design is not restricted to the described embodiments, described in above-described embodiment and description
Principle, on the premise of without departing from the design spirit and scope, the invention also has various changes and modifications, these change
Change and improve and both fall within the range of claimed the design.The invention claims scope by appending claims
And its equivalent thereof.
