Abstract
The utility model provides a hydraulic fast testing and displaying device for concrete stirring vehicles. When the utility model is designed, a pressure-testing point is provided with a steel-ball sealing fast joint which is provided with a dust-prevention nut. When the nut is screwed off, a fast pressure-testing flexible pipe is inserted, wherein, the other end of the fast pressure-testing flexible pipe is provided and connected with a pressure meter. The pressure meter displays concrete pressure values. The assembly and the disassembly of the utility model can be carried under the running state of a hydraulic system. The pressure test is convenient, and the hydraulic system is not polluted. The utility model can also be used for exhausting air for systems and sampling oil. The problem that when in a test, the hydraulic system has a vicious circulation because a concrete stirring vehicle works under dust and slurry environments for a long time can be solved by the utility model.
Description
Technical field
The utility model relates to truck mixer and hydraulic test field, and particularly a kind of truck mixer is with the quick test display apparatus of hydraulic pressure.
Background technology
For a long time, hydraulic system accounts for 70-80% by the fault that cleanliness cause, and in the handling failure process, environment is unfavorable during owing to pressure detection inconvenience and detection, further worsens the cleanliness situation of hydraulic system, causes vicious cycle.The pressure tap screw be must open during pressure detection, pressure tester, thread up again inserted.Owing to often detect, during pressure tap place screw thread damage is arranged, little problem causes big trouble again.For addressing the above problem, the utmost point need have a kind of device for quick testing of hydraulic pressure fast and easily.
Summary of the invention
The purpose of this utility model provides a kind of truck mixer with the quick test display apparatus of hydraulic pressure.
The rapid-acting coupling that seals at pressure tap configuration steel ball locking type when the technical solution adopted in the utility model is product design, rapid-acting coupling is made up of plug and socket two parts, plug is fixedly connected on the pressure tap position, and socket is connected an end of quick pressure measurement flexible pipe in advance.Have dustproof nut on the plug of joint.Screw off nut, utilize the cooperation of the socket and plug of rapid-acting coupling, but quick pressure measurement flexible pipe on the plug-in mounting.And adorn tensimeter at the other end of quick pressure measurement flexible pipe, tensimeter shows concrete pressure value.Can equip this proving installation for a long time during normal the operation; Also can pull down proving installation, the dustproof nut that the quick pressure measuring tie-in of screwing on carries.Fast the dress of the socket of pressure measurement flexible pipe and the plug of pressure measuring tie-in fast with tear open and can under the hydraulic system running status, carry out.
This usefulness the utlity model has following beneficial effect:
1, adopt the utility model failure judgement detected pressures convenient, not the contaminating fluid pressing system.
2, long-term device uses and can find potential faults by stress problems.
3, also can be used for the sampling of system deflation and fluid.
4, fast the dress of pressure tester and pressure measurement plug fast with tear open and can under the hydraulic system running status, carry out.
5, truck mixer is worked in the environment of dust and mud for a long time, easily hydraulic system is caused vicious cycle, uses the utility model fast hydraulic pressure test display apparatus to free this puzzlement in the measurement.

Embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
Consult each accompanying drawing, marked the position that needs pressure tap in truck mixer drum driven system, at the plug 1 of these pressure tap configuration steel ball locking type sealing rapid-acting couplings, and the socket 2 of rapid-acting coupling has been connected an end of quick pressure measurement flexible pipe 4.Have dustproof nut on the plug 1, screw off nut, the quick pressure measurement flexible pipe 4 of plug-in mounting, the other end attaching tensimeter 3 of flexible pipe shows concrete pressure on the number by tensimeter 3.
This rapid-acting coupling is made of socket 2 and a plug 1 of a high-quality steel, can be used for high pressure, middle pressure and low pressure, and according to different occasions, joint can be by stainless steel, brass or duralumin manufacturing.The seal of institute's adapted is nitrile seal or fluororubber or EP rubbers seal.The thread bush 201 of the socket 2 of rapid-acting coupling and the thread bush of plug 1 101 are axially to settle, and thread bush can keep internal mechanism motionless and open valve played the effect of mechanical braking, therefore, no matter how flow direction can both guarantee complete equipilibrium opens.The valve Huang 102 of valve of socket 2 yellow 202 and plug 1 remains on valve in its pedestal, therefore disconnects when connecting in low pressure also guaranteeing good sealing property.The valve 203 of socket 2 and the valve 103 of plug 1 all are equipped with static seal, utilize its automatic axial to move to have guaranteed in the moment that disconnects and close closed loop and instant sealing, even its structure and shape can both make valve withstand high pressure under more critical off-state safely.Combination nothing leakage after in a single day the O-ring seals 204 assurance plugs 1 of socket 2 and socket 2 connect between them.The pressurized seal plastic yield is protected and prevented to the anti-extrusion pressure ring 205 of socket 2 to O-ring seals in connection and disconnection process; The nitrile seal anti-extrusion pressure ring of nylon, the anti-extrusion pressure ring polytetrafluoroethylmaterial material of other seals.The steel ball chamber 206 built-in steel balls of socket 2, locking is reliable, and allowing has some rotations between plug 1 and the socket 2, to prevent the distortion of flexible pipe before the supercharging.The steel ball groove 104 of plug 1 snaps in and tight lock for steel ball when plug 1 is connected with socket 2.The locking sleeve 207 of socket 2 connects rapidly by moving around in the axial direction simply.Like this, the rapid-acting coupling of this steel ball locking type can make two instantaneous connections of hydraulic circuit and disconnection.
Auto lock and unlatching have guaranteed simple to operate and rapid.The project organization of joint and material have guaranteed safe and reliable to operation, after the connection, all movable parts all on restriction point by mechanical caging, therefore open no matter flow direction and rapids how, can both guarantee complete equipilibrium.Figure 4 illustrates the position of the plug 1 of several pressure measuring tie-ins in the truck mixer drum driven hydraulic system, also show cylinder 8, truck mixer reductor 5 (PLM9), Variable plunger pump 6 (A4VTG90HW/32L-NLD10F001S) and transfer case terminal pad 7 among the figure.
