Abstract
A speed regulation winding engine with hydraulic driving consists of oil pump, hydraulic valve set, oil tank and hydro-motor. It is featured as connecting oil pump to motor and valve set, oil tank to oil pump and valve set being connected with hydro-motor, hydro-motor to winding engine. The present invention uses motor to drive oil pump for supplying oil to hydro-motor so as to drive winding roll or gear in stead of using motor directly to drive reducer in original design.
Description
Technical field
The invention belongs to winch (hoisting crane) drive technology field.
Background technology
Traditional winch (hoisting crane), type of drive are to adopt machine driven system, and its transmitting ratio is certain, promptly by retarder and gear cluster driving system, drive big gear wheel and reel and rotate, and steel rope on reel, is mentioned the object of being carried.The velocity of rotation of the drive motor of winch is certain in working order substantially, in some sense, winch similarly is an automobile that has only shelves, can't satisfy different ground-surface requirements, owing to have only a speed, when promoting heavy duty, no matter be frame or basis, suffered impact load all is a maximum impact load.For winch, satisfy different rate requests, speed is changed, and the method for changing speed of winch use at present is to change power frequency, promptly change the frequency of drive motor, directly finish speed change by frequency converter.Since be to change frequency, necessary increase equipment and investment, the waste of power of increase frequency converter.In some industry the speed and the hoisting force of winch had some special requirements, as the gate control process in power station, in the stop gate water-rinsing process, must be at a slow speed, little power is mentioned flashing valve, finish this process after, again must fast lifting; When high-lift winch starting gate, must be at a slow speed, energetically; Seeking Truth is quick again during lift gate.Such operating mode, frequency converter fails to satisfy requirements.
Summary of the invention
Purpose of the present invention provide in order to solve above-mentioned the deficiencies in the prior art just a kind of very simple realization winch have the level, infinite speed variation, change the size and the speed speed of hoisting force, satisfy the requirement of different operating modes, and, all right simplified apparatus is saved the hydraulic-driven variable-speed winch of investment.
The objective of the invention is to be achieved through the following technical solutions.
The hydraulic-driven variable-speed winch, the driving system of winch (hoisting crane) is a power hydraulic system, and this hydraulic actuator includes oil pump, hydraulic valve bank, fuel tank and oil motor, and its connecting mode is that the oil pump power intake connects with motor; Mouth connects with the valve group; Oil pump and valve group connect with fuel tank by oil inlet; The input port of oil pump connects with fuel tank, and valve group and oil motor input, mouth link, and the oil motor clutch end connects with winding gear or reel.
The valve group is made up of by pass valve, flow regulating valve, solenoid directional control valve, check valve and shuttle valve;
The present invention changes the machine driven system of former winch into power hydraulic system, directly drives retarder by original motor, change into and drive the oil pump rotation, oil pump rotates by valve group fuel feeding the oily sucking-off feed cock group of fuel tank to HM Hydraulic Motor, drive reel or gear and rotate.By pressure that changes the input oil motor and hoisting force and the speed that flow changes winch, speed change and the variable force of finishing goods promote.Advantage of the present invention is:
1, can in speed range, change speed as required arbitrarily, realize that level, infinite speed variation are arranged.
2, can in range of capacity, change the size of hoisting force as required arbitrarily, realize that permanent power, permanent moment of torsion and specified force promote object.
3, do not have the overladen situation of winch or hoisting crane fully, therefore, there is not any destructive consequence in the present invention.
Further set forth content of the present invention below in conjunction with Figure of description.
Description of drawings
Fig. 1 is a system of the present invention connection diagram;
Fig. 2 is a specific embodiment of the invention hydraulic efficiency pressure system connection diagram.
The specific embodiment
The composition of power hydraulic system is made up of oil pump 1, valve group 2, fuel tank 3 and oil motor 4 as shown in Figure 1.Whole power hydraulic system is arranged between motor 5 and the winding gear 6, wherein the input end of oil pump 1 connects with motor 5, mouth connects with valve group 2, oil pump 1 and valve group 2 connect with fuel tank 3 by oil return pipe 10 and oil inlet 11 respectively, valve group 2 connects with the input end of oil motor 4, oil motor 4 mouths connect with winch and miniature gears 5, and valve group 2 is mainly combined by by pass valve 13, flow regulating valve 14, solenoid directional control valve 15, check valve 16 and shuttle valve 17, and some auxiliary members commonly used of joining.Oil motor 4 is actuating units, and it is transferred to winch miniature gears 6 with hydraulic coupling, drives big gear wheel 7 by miniature gears 6 and rotates, and then reel 8 is rotated, and drives goods 9 liftings by hoisting rope.According to the pressure of need of work control system, flow and direction also can adopt oil pump oneself to regulate.The most basic system pressure control is by 13 controls of the by pass valve in the valve group 2, and flow is by 14 controls of the flow regulating valve in oil pump 1 and the valve group.
As requested, can carry out different combinations, form throttling governing, volumetric speed control, volume throttling governing, permanent power, permanent torque adjustment working barrel 1, valve group 2 and oil motor 4.Because the development of low-speed big oil motor, winch can save equipment parts such as retarder and large and small gear 7,6 in normal conditions, and the equipment total cost is reduced, and simple to operate, reliability improves, and the overload situation can not occur.
The principle of work that the present invention is concrete and the system of preparation connect as shown in Figure 2, in its bold box is valve group 2, acting as of concrete connecting mode, airfilter 19 plays the make peace effect of filtered air impurity of fuel tank 3 pressure and external air pressure one that keeps, gate valve 18 is used to overhaul, oil suction oil filter 20 and time liquid oil filter 23 are used for filtering the impurity of hydraulic oil, response pressure table switch 24 can make compression indicator 12 by electromagnetic relief valve 13 control system pressure, 25 is the temperature liquid level meter, the left side of three position four-way electromagnetic valve commutation 15, in, right position is just played respectively and is changeed, stop, the effect of counter-rotating, the effect of shuttle valve 17 is to open mechanical brake, be about to brake cylinder 21 and connect the using system operation, one-way throttle valve 14 is used for speed governing, its principle is for opening shuttle valve 17 when limit, 3-position 4-way solenoid directional control valve 15 left and right sides, its spool moves take-off the brake oil cylinder 21 makes oil motor 4 in running order, hydraulic oil enters one-way throttle valve 14 simultaneously, make this throttle valve adjustment enter the oil mass of oil motor 4, thereby play the effect of governing speed, and hydraulic control one-way valve 16 is effects of playing the oil motor hydraulic lock, opens hydraulic lock under pressure.As the need maximum speed, can open bi-bit bi-pass solenoid directional control valve 22 formation bypass hydraulic circuits and directly enter oil motor 4, make the formation maximum speed.When goods 9 needs when putting down, 3-position 4-way solenoid directional control valve 15 is to position, the right, hydraulic oil is opened brake cylinder 21 through shuttle valve 17 and is formed counter-rotating, control through flow regulating valve 14 during oil return, can prevent that free falling body state from appearring in goods, when goods slack, or when not working, 3-position 4-way electromagnetic switch valve position is closed oil circuit total system is not worked to middle.
