The structure is characterized in that a transparent observation pipe (13) is arranged in the oil discharge pipeline. And the observation pipe (13) is fixed on an easy-visible position of the detection platform. And a three-position-four way electromagnetic valve (6) is arranged in the oil supply pipeline. The oil discharge pipeline includes a two-position tee electromagnetic valve (11).
Description
Affiliated technical field
The utility model belongs to the vehicle testing technique field, relates in particular to automobile hydraulic direction machine examination scaffold tower.
Background technology
The interior leakage that the detection of automobile hydraulic direction machine is related to the direction machine detects.Its method is under the situation of the rotary valve of closing hydraulic traversing mechanism, impose operating oil pressure at the oil-in of direction machine, and the fuel-displaced situation of the flowline of direction of observation machine obtains qualitatively (perhaps being non-accurate quantification) result simultaneously.Existing automobile steering machine examination scaffold tower is not the interior leakage attachment device of detection side to machine specially; But when carrying out this detection, the flowline of removing direction machine is observed; Inconvenience, and through regular meeting's pollution detection platform and workplace.
Summary of the invention
In order to improve the convenience of operation, the utility model provides omission geodesic structure in a kind of automobile hydraulic direction machine.
The technical solution of the utility model is:
In the fuel-displaced pipeline of direction machine, transparent observation tube is set, and easily looks the position what observation tube was packed in monitor station.That is:
Omission geodesic structure in a kind of direction machine of automobile hydraulic direction machine examination scaffold tower, comprise the oil feed line that is routed to direction machine oil-in and continue from the fuel-displaced pipeline of direction machine oil-out, it is characterized in that: in fuel-displaced pipeline, be provided with transparent observation tube, and observation tube be packed in monitor station easily look the position.
The beneficial effects of the utility model: owing to the utlity model has above-mentioned architectural feature, do not need the flowline of removing direction machine to observe when then omission is surveyed in the travel direction machine, also can not pollute the workplace.So use more convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a synoptic diagram of the present utility model.
Fig. 2 is the synoptic diagram that has adopted automobile hydraulic direction machine examination scaffold tower of the present utility model.
Embodiment
As shown in the figure, omission geodesic structure in a kind of direction machine of automobile hydraulic direction machine examination scaffold tower, comprise the oil feed line that is routed to direction machine oil-in and continue from the fuel-displaced pipeline of direction machine oil-out, it is characterized in that: in fuel-displaced pipeline, be provided with transparent observation tube 13, and observation tube 13 be packed in monitor station easily look the position.
As shown in Figure 2, a three position four-way electromagnetic valve 6 is arranged in the oil feed line; Comprise two-position three way magnetic valve 11 in the fuel-displaced pipeline.
Automobile hydraulic direction machine examination scaffold tower as shown in Figure 2, elder generation is according to the sense of rotation actuating motor of hydraulic traversing mechanism boost pump 2 (vane pump or gear-type pump) during use, by surplus valve 4 pressure is transferred to the required pressure of hydraulic traversing mechanism 7, forms a loop by solenoid valve 5,6 again and make hydraulic oil get back to fuel tank 100.
Detect when leaking in the hydraulic traversing mechanism 7, connect three position four-way electromagnetic valve 6, hydraulic oil enters hydraulic traversing mechanism 7 by A oil-out, oil pipe 8, get back to fuel tank by oil pipe 10, solenoid valve 6 again and form the loop, the input shaft 9 of rotating hydraulic direction machine 7, hydraulic traversing mechanism 7 rotary valves cut out, connect solenoid valve 11 then and hydraulic oil another oil-out by solenoid valve 11 entered observe fuel-displaced (glass) sighting tube 13 of hydraulic traversing mechanism, at this moment can according to hydraulic traversing mechanism fuel-displaced how much judge the size of leaking in the hydraulic traversing mechanism.
Automobile hydraulic direction machine examination scaffold tower as shown in Figure 2 can also be used to boost pump pressure and boost pump flow are detected:
When carrying out the boost pump pressure detection, two cycle time relay (not shown)s of control electromagnetic valve 5 are set to out stop in 5 seconds 10 seconds states, connect the power supply of two cycle time relay then, and the time relay is started working; Solenoid valve 5 cuts out hydraulic oil circuit 5 seconds, at this moment observe whether tensimeter 3 shown pressure are required pressure, solenoid valve 5 work stopped 10 seconds after 5 seconds, two cycle time relay was closed after 5,6 times so repeatedly, and the pressure detection of hydraulic traversing mechanism boost pump 2 finishes;
When carrying out the boost pump flow detection, the working time of the time relay (not shown) of control electromagnetic valve 6 is set to 60 seconds earlier, again turn-on time relay, at this moment three position four-way electromagnetic valve 6 is started working, hydraulic oil enters the oil-in of flowmeter 12 by the B oil-out of solenoid valve 6, gets back to fuel tank by the oil-out of flowmeter 12 again; Timing arrives 60 seconds the moment, and three position four-way electromagnetic valve 6 is closed its B oil-out under the effect of the time relay.What at this moment flowmeter 12 was shown is exactly (per minute) working flow of hydraulic traversing mechanism boost pump 2.
Claims (2)
1. omission geodesic structure in the direction machine of an automobile hydraulic direction machine examination scaffold tower, comprise the oil feed line that is routed to direction machine oil-in and continue from the fuel-displaced pipeline of direction machine oil-out, it is characterized in that: in fuel-displaced pipeline, be provided with transparent observation tube (13), and observation tube (13) be packed in monitor station easily look the position.
2. omission geodesic structure in the direction machine of automobile hydraulic direction machine examination scaffold tower according to claim 1 is characterized in that: a three position four-way electromagnetic valve (6) is arranged in the oil feed line; Comprise two-position three way magnetic valve (11) in the fuel-displaced pipeline.
