Description of drawings
Above-mentioned is only the general introduction of technical solutions of the utility model, and for can clearer understanding technological means of the present utility model, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the utility model wind power generating set hydraulic impeller locking device.
Embodiment
See also shown in Figure 1ly, a kind of wind power generating set hydraulic impeller of the utility model locking device mainly comprises fuel tank 1, oil hydraulic pump, action oil hydraulic cylinder 3 and stop pin 4.
Wherein, action oil hydraulic cylinder 3 horizontal arrangement, stop pin 4 with move the piston 31 of oil hydraulic cylinder 3 and be fixedly connected with, and between piston 31 and cylinder bottom mounting spring 34.Between the filler opening of fuel tank 1 and oil hydraulic pump, between the filler opening 32 of the oil outlet of oil hydraulic pump and action oil hydraulic cylinder 3, all be connected by oil pipe between the oil outlet 33 of action oil hydraulic cylinder 3 and fuel tank 1, and on each oil pipe, valve 51 is set respectively, 52,53.
The utility model is provided the coupling mechanism force of impeller by spring 34.When design, can select according to different situations the specification of spring, usually need to consider material, hardness, the intensity of spring, and calculate required spring size according to elastic force and the relation F=KX of on-the-spot actual demand.
Oil hydraulic pump of the present utility model can adopt hydraulic hand-pump as shown in the figure, because operation is not frequent, manual operating device can reach the control requirement, can reduce simultaneously the fabricating cost of device integral body, in addition, manually-operable also be more convenient for stop pin and locking plate to the hole process in regulate its mutual alignment.The concrete structure of the hydraulic hand-pump that the utility model adopts forms and comprises small oil tank 21, be arranged on small oil tank 21 into and out of hydraulic fluid port, be arranged on the piston 22 in small oil tank 21, and the lever handle 23 that is fixedly connected with piston 22.
The structure of action oil hydraulic cylinder can be selected as required by those skilled in the art.Structure is as example shown in to scheme, and spring 34 is arranged in the left side cylinder body of action oil hydraulic cylinder, stop pin 4 is fixedly connected with piston action oil hydraulic cylinder 3 31 right sides, and filler opening 32, the oil outlet 33 of action oil hydraulic cylinder 3 all are arranged on the cylinder side wall of right side.
The position of mounting point of the present utility model and existing stop pin is identical.When unclamping, throttle down 52,53 is opened valve 51, mentions lever handle 23 piston 22 is moved up, and the oil pocket volume of piston 22 lower ends increases, and forms parital vacuum, the oil suction from fuel tank 1 of the filler opening of oil hydraulic pump.Afterwards, throttle down 51,53 is opened valve 52, firmly depress lever handle 23, piston 22 moves down, and 22 times cavity pressures of piston raise, the fluid of cavity of resorption forces piston 31 to drive stop pin 4 and is moved to the left, holddown spring 34 in the right side cylinder body of oil pipe input action oil hydraulic cylinder 3.Afterwards, throttle down 52 is opened valve 51, again mentions lever handle 23 oil suctions, and due to valve function, fluid can not flow backwards, thereby has guaranteed that piston 31 does not move right.Constantly back and forth pull lever handle 23, just can constantly be pressed into fluid in action oil hydraulic cylinder 3, make spring 34 constantly compressed, stop pin 4 also is moved to the left gradually, finally unclamps locking.
During locking, throttle down 51,52 is opened valve 53, and the fluid that the action oil hydraulic cylinder is 3 li flows back to fuel tank 1 by oil pipe, and piston 31 moves right under the effect of spring 34, and final stop pin coordinates with locking plate, realizes the locking of impeller.
In order further to improve operating efficiency, valve 51,52 adopts one-way valves, and valve 53 adopts stop valves, and namely autocontrol valve 51,52 fluid flow to, and need not opening and closing operations.
The utility model gets final product the position of control action oil hydraulic cylinder 3 inner carriers 31 by controlling oil hydraulic pump, thereby driving stop pin 4 moves, adopt the hydraulic pressure to control the pine of impeller lock rationed marketing and tight, avoided stop pin because of the difficult tight phenomenon of difficult pine that the reason such as get rusty causes, also bring convenience for operating simultaneously.
Furthermore, the utility model also can arrange limit switch 41 on stop pin 4, and with this limit switch 41 and the signal picker communication connection that is provided with tutorial light.Limit switch 41 adopts logical zero and 1,1 to represent stop pin locking, not locking of 0 representative.When locking puts in place, locking plate touches limit switch 41, and feedback signal is uploaded to signal picker, signal picker is controlled corresponding tutorial light action, operator can point out by tutorial light, clear, judge impeller accurately and whether lock, thereby effectively avoid because stop pin is not locked the accident that causes.
The above; it is only preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection domain of the present utility model.
