Detailed description of the invention
Fig. 1 is the attachment structure schematic diagram of hydraulic capstan pilot system in embodiment；
Fig. 2 is hydraulic capstan pilot system layout.
Specific embodiment
In the following, being described in further details in conjunction with attached drawing to the utility model.
As shown in Figure 1, present embodiment discloses a kind of hydraulic capstan pilot systems, the performance test for hydraulic capstan.
The pilot system includes the first hydraulic capstan system 1, the second hydraulic capstan system 2 and tension sensor 3.
First hydraulic capstan system 1 includes being tested capstan winch 11, connecting the first electricity to provide power with subject capstan winch 11
Control proportional variable pump 12, the first alternating current generator 13, the first data acquisition device to drive the first Electric Proportional variable-volume pump 12.
Wherein, the first data acquisition device is the sensor of the data such as temperature collection, pressure, flow, to monitor the ginseng of subject capstan winch
Number, is specifically provided with first pressure gauge 15 and first flowmeter 16 in this example.Second hydraulic capstan system 2 includes load capstan winch
21, connect with load capstan winch 21 to power is provided the second Electric Proportional variable-volume pump 22, to drive the second automatically controlled ratio change
The second alternating current generator 23, the second data acquisition device of amount pump 22.And the second data acquisition device and the first data acquisition device
Function it is similar, to monitor load capstan winch parameter, be specifically provided with second flowmeter in this example.Tension sensor 3 connects
It connects between the output end of subject capstan winch 11 and the output end of load capstan winch 21.
In order to make the more stable safety of operation of the pilot system, the first hydraulic capstan system 1 further includes the first electricity
Magnetic overflow valve 14, first electromagnetic relief valve 14 are connect with first Electric Proportional variable-volume pump 12.Correspondingly, described second
Hydraulic capstan system 2 further includes the second electromagnetic relief valve 24, and second electromagnetic relief valve 24 becomes with the described second automatically controlled ratio
22 connection of amount pump.To realize safeguard protection.
Further, the second hydraulic capstan system 2 also has electro-hydraulic reversing valve 26, and the electro-hydraulic reversing valve 26 connects
Between the load capstan winch 21 and second Electric Proportional variable-volume pump 22.
As shown in Fig. 2, the pilot system also has there are two mounting platform 4 and is arranged between two mounting platforms 4
Ground channel 5, the subject capstan winch 11 and the load capstan winch 21 are separately mounted on two mounting platforms 4, are tested capstan winch 11
