Below in conjunction with the hydraulic schematic diagram shown in Fig. 1, the operation principle of this embodiment winch control system is illustrated:

(1) when brake control valve 4, lifting oil passage control valve 3, balanced valve 8 and oil pump 2 equal normal operation, winch control system is capable of the normal lifting process of weight:

Due to lifting oil passage control valve 3, balanced valve 8 and the equal normal operation of oil pump 2, therefore, switching between its first working position and second working position by controlling lifting oil passage control valve 3, the A that can make to open connects with in oil pump 2 and fuel tank 1 and mouthful B that falls connects with another in oil pump 2 and fuel tank 1。And, when brake control valve 4, lifting oil passage control valve 3, balanced valve 8 and oil pump 2 equal normal operation, first reversal valve 132 and the second reversal valve 141 are in respective first working position, owing to the first reversal valve 132 is in its first working position, therefore, the duty of hoist brake 5 is controlled by brake control valve 4；Owing to the second reversal valve 141 is in its first working position, therefore, open A and the connection oil circuit two-way stop that falls between mouthful B at emergent oil route controller 14 place of motor。

Now, control brake control valve 4 and switch to its second working position, and control the second reversal valve 3 is in its first working position, then brake oil oil sources X can pass through the working chamber fuel feeding that brake control valve 4 is hoist brake 5, and oil pump 2 connects with the A that opens, mouthful B that falls connects with fuel tank 1, so that hoist brake 5 is in brake release state, open A oil-feed and mouthful B oil return that falls of hoist motor 6 simultaneously, hoist motor 6 rotates to first direction, drive the inside rope closing of elevator 7, weight is raised, it is achieved weight hoists。

Similarly, if controlling brake control valve 4 to switch to its second working position, and control the second reversal valve 3 switches to its second working position, then brake oil oil sources X can pass through the working chamber fuel feeding that brake control valve 4 is hoist brake 5, and oil pump 2 connects with mouthful B that falls, the A that opens connects with fuel tank 1, so that hoist brake 5 is in brake release state, fall mouthful B oil-feed and the A oil return that opens of hoist motor 6 simultaneously, hoist motor 6 rotates to second direction, elevator 7 is driven outwards to put rope, by weight height reduction, it is achieved weight is transferred。Further, in this process, by regulating the size of the damping being arranged at balanced valve 3 second working position, it is possible to regulate the lowering velocity of weight。

And if control brake control valve 4 is in its first working position, then the working chamber of hoist brake 5 connects with fuel tank 1, and hoist brake 5 is in on-position, then hoist motor 6 and elevator 7 all cannot rotate, and weight rests on a certain level altitude position。

(2) after elevating control lost efficacy, namely when, after in brake control valve 4, lifting oil passage control valve 3 and balanced valve 8, multiple or whole inefficacy, winch control system is capable of the emergent decentralization process of weight:

After apparatus for controlling of lifting lost efficacy, then winch control system cannot realize the normal lifting process of weight again, hangs skyborne weight and can bring potential safety hazard, need to transfer in time to ground。Such as, when brake control valve 4, lifting oil passage control valve 3 and balanced valve 8 all lost efficacy, the uncontrollable hoist brake 5 of brake control valve 4 is in brake release state, and open A and all cannot connect with any one in oil pump 2 and fuel tank 1 with mouthful B that falls, therefore, the normal lifting process of weight cannot realize。

Now, Non-follow control the first reversal valve 132 and the second reversal valve 141 switch to respective second working position, and are opened by motor 123 and be at duty。Owing to the first reversal valve 132 is in its second working position, hoist brake 5 connects with accumulator 131, and accumulator 131 is the working chamber fuel feeding of hoist brake 5, and therefore, hoist brake 5 is in brake release state。Owing to the second reversal valve 141 is in its second working position, therefore, the A and fall and connect oil circuit along by the A direction unilaterally connected to mouthful B that falls that opens between mouthful B of opening at emergent oil route controller 14 place of motor。Owing to motor 123 works, slippage pump 121 can for mouthful B repairing that falls。Visible, the now rotation of elevator 7 and hoist motor 6 is no longer influenced by restriction, and hoist motor 6 can form mouthful B-that the falls emergent oil route controller 14-of A-motor that opens and fall the circulating oil path of mouthful B, so, elevator 7 and hoist motor 6 all can rotate to second direction under the effect of weight gravity, make weight height reduction, and finally transfer to ground, it is achieved weight is met an urgent need decentralization process。In this process, it is possible to by regulating the size of the first damping 143, regulate the lowering velocity of weight so that it is meet and be actually needed。

The winch control system of this embodiment is applicable to the various situations that apparatus for controlling of lifting lost efficacy, and is wherein particularly suited for the failure case that crane disorderly closedown causes。During due to crane disorderly closedown, oil pump 2 cannot work, and therefore, oil pump 2 cannot be the lifting oil passage control valve 3 as motor steering control device and balanced valve 8 fuel feeding；And; brake control valve 4 and lifting oil passage control valve 3 all lose power supply; brake control valve 4 accordingly, as arrester control device cannot switch to the second working position, and lifting oil passage control valve 3 cannot switch between the first working position and the second working position; and can be only in interposition; the hydraulic control end of balanced valve 8 is inoperative, and balanced valve 8 also cannot switch to its second working position, it is seen that; during crane disorderly closedown, whole apparatus for controlling of lifting all lost efficacy。And when crane disorderly closedown, owing to the first reversal valve 131 of brake emergency control apparatus and the second reversal valve 141 of the emergent oil route controller of motor are hand-operated direction valve, not by the restriction of power supply, therefore, the transposition action of the two is not all by the impact of crane disorderly closedown, and, owing to the emergent recharging oil device 12 of motor is provided with independent slippage pump driving device, therefore, the emergent recharging oil device 12 of motor also is able to the normal operation when crane disorderly closedown, thereby may be ensured that and remain able to when crane disorderly closedown realize the emergent lowering function of weight。Certainly, except adopting hand-operated direction valve, the first reversal valve 131 and the second reversal valve 141 adopt pilot operated directional control valve can also realize the normal operation when crane disorderly closedown。

Visible, based on the winch control system of this embodiment, after apparatus for controlling of lifting lost efficacy, should only need control handle or button just can start emergent control device of transferring and weight transferred safely to ground, simple to operate, it is easy to accomplish, and risk is relatively low。And, owing to namely this winch control system self is capable of the emergent lowering function of weight, another crane need not be recalled hung by weight to ground, therefore, in terms of existing technologies, it can realize much sooner and safely, and weight is emergent transfers control function, has the advantages such as fault handling time is short, troubleshooting difficulty is low。In addition, owing to the winch control system of this embodiment utilizes weight own wt to realize the emergent lowering function of weight, power need not be provided actively to control, even if adopting the emergent recharging oil device 12 of motor, its oil compensation pressure is relatively low, therefore, to realize power attenuation during weight emergent lowering function relatively low for this embodiment winch control system such that it is able to the effectively save energy。

Another aspect of the present invention additionally provides a kind of crane including winch control system of the present invention。Owing to the winch control system of the present invention has above-mentioned beneficial effect, therefore, the crane of the present invention also has corresponding technique effect, repeats no more herein。

The foregoing is only the exemplary embodiment of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention。
