Carry out the command speed test, under rated load, by the given instruction speed of specified winch revolution, the detection speed error;
Carry out braking ability test, tested winch turn-offs the oil sources power supply, the braking potential during the check dead electricity, test load is pressed 150% of the specified pulling force of single wire rope, pressurize 10min, tested winch slippage should not occur, loads the winch hydraulic pressure indicator and shows corresponding load pressure;
Carry out the ratchet stop test, tested winch is with the pawl ratchet combination, winch stops operating, the test steel rope adds load by 150% of the specified pulling force of single wire rope, pressurize 10min, check ratchet, ratchet and support situation, load the winch hydraulic pressure indicator and show corresponding load pressure.
According to the pattern and the predelivery test method of large-scale winch of the present invention, adopt two winchs to drawing mutual load test, just can carry out all Test items of national regulations such as static weight, live load, command speed and deceleration and stopping performance.
At the trial two bench teats are tested winch and be close to placement Face to face, two reels are connected with steel rope, make pull of steel wire become the internal force of winch, and winch need not be fixed, and can test at workshop with ground.Test adding intermediate liquid compressing cylinder bracing or strutting arrangement between the winch at two bench teats, be used to regulate two pull of steel wire equilibriums.The present invention all utilizes the drive system of winch self, need not acquire special purpose test equipment, has solved the difficult problem of large-scale, heavy winch test load operating effectively, and can save a large amount of equipment investments and proving ground.
The pattern of large-scale winch of the present invention and predelivery test method are applicable to the winch test of double crosslinking drum, single drum and all kinds of reels.
Description of drawings
Fig. 1 is that two winchs by the predelivery test method of large-scale winch of the present invention are to drawing the scheme drawing of arrangement.
Fig. 2 is two scheme drawings that reel couples together with steel rope of winch.
The specific embodiment
Referring to Fig. 1 and Fig. 2, according to the predelivery test method of a kind of large-scale winch of the present invention, use two bench teats to test winch, wherein one is tested winch 1, another is loading winch 2, or in test these two winchs is replaced mutually.Use two identical winch model machines, be convenient to when type test, load mutually.
The present invention adopts the following step to carry out pattern and predelivery test:
Two bench teats are tested winch be close to placement Face to face, and two reels of winch are coupled together (as shown in Figure 2) with steel rope 3, make pull of steel wire become the internal force of winch, and winch need not be fixed with ground.
Test adding intermediate liquid compressing cylinder bracing or strutting arrangement 4 between the winch at two bench teats, the bracing or strutting arrangement that preferably uses two covers to be used for connecting between the winch is to regulate two pull of steel wire equilibriums.The angle of batching that guarantees steel rope during test is not more than 3 °, and guarantees two steel rope stress equalizations.All utilize the drive system of winch self, need not acquire special purpose test equipment.
