Abstract
The utility model relates to an intelligent type gear case elastic support for a blower, which comprises a framework, wherein upper and lower elastic bodies are arranged inside the framework, hydraulic air bags are arranged in both of the elastic bodies, ports of the outer ends of the hydraulic air bags of the upper and lower elastic bodies are connected with pressure sensors, and the two pressure sensors are connected with a controller through a circuit. The two pressure sensors are respectively used for detecting pressure inside the hydraulic air bags inside the elastic bodies at two ends and sending pressure values to the controller, when the pressure exceeds a certain value, warning can be carried out, and when the pressure exceeds the ultimate pressure, forced stoppage for protection can be carried out. In the utility model, limiting positioning stop blocks are arranged in the elastic extension limiting positions of the elastic bodies inside the framework, when the sensor or the controller goes wrong, the supporting rigidity of a torque arm is increased to prevent excessive twisting. The intelligent type gear case elastic support for the blower can be used for monitoring the variations of the rigidity of the elastic bodies at any time, and can better protect the safety during the mechanical transmission of the blower, can be used for alarming in real time, and can reduce the work difficulty of maintainers.
Description
Technical field
The utility model relates to a kind of blower fan auxiliary device, especially a kind of blower fan special intelligent type gear-box elastic support.
Background technique
The wind-driven generator group wheel box elastic support is except the support teeth roller box at present, and it can also play the effect that absorbs fluctuating load, damping, can well protect gear-box.The blower fan gear-box toggle of all models all adopts elastic support to connect both at home and abroad at present.What the elastic support elastomer adopted is a series of processing of natural rubber process, bonding forming, and the rigidity of rubber is to decide according to blower fan load, but rigidity is regulated and the stability of operation is the basis that guarantees the blower fan reliable operation.Common elastic support has mechanical type elastic support and hydraulic type elastic support.
Mechanical elastic supports, at present the most frequently used, elastomer rigidity is by jacking block adjusting up and down, and it respectively has one to regulate bolt up and down, thereby screw in the rigidity that the consistency that promotes jacking block change rubber changes rubber body by bolt, can reflect rubber from the bolt screw-in length and put forward rigidity.
This product structure is simple, easy to operate, but less stable.As time goes on, creep can take place in rubber body, its rigidity can slowly diminish, be difficult to control and regulate rigidity by jacking block, can not accurately guarantee the conformity of four rubber body rigidity of two toggles, so be difficult to when being subjected to load guarantee that two toggles of gear-box are stressed evenly, cause reversing of toggle easily.Next is exactly that this structural rigidity changes and is difficult to find, in case find untimely, bigger to the Safety Effect of gear-box.
The hydraulic type elastic support, there is a hydraulic bladder its rubber body inside, the two-side elastic body is communicated with (interconnection up and down) by hydraulic pipe line, when regulating rubber body rigidity by an one drag two topping-up pump simultaneously to two pairs of elastomeric hydraulic air bags fluid injection up and down, when reaching certain pressure and guaranteed rubber body rigidity.This structure couples together the upper and lower sides of both sides rubber body, can guarantee the stressed even of gear-box both sides toggle, has effectively prevented reversing of toggle.
As time goes on this structural disadvantages is exactly, and rubber body can fluff, and gasbag pressure can tail off, and rubber body rigidity can diminish thus, and this variation guardian is difficult to find.In case secondly be exactly that air bag is revealed, rubber body rigidity will sharply descend, and will be untimely if the guardian finds, fierce vibrations will take place in gear-box, and the elastic coupling flexible coupling of gear-box and gear-box and generator will take place badly damaged.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art; provide a kind of and can monitor the elastomer stiffness variation at any time; the Security of better protection blower fan mechanical transmission, but Realtime Alerts alleviate the blower fan special intelligent type gear-box elastic support of guardian's work difficulty.
For achieving the above object, the utility model adopts following technical proposals:
A kind of blower fan special intelligent type gear-box elastic support, comprise framework, be provided with two elastomers up and down in the framework, be equipped with hydraulic bladder in two elastomers, described two elastomeric hydraulic bladder outer end interfaces up and down connect a pressure transducer respectively, and described pressure transducer links to each other with controller by circuit respectively.
Elastomeric elastic extension extreme position is provided with limit positive stop in the described framework.
The utility model is connected to a pressure transducer respectively at the upper and lower end elastomeric hydraulic air bag outer end of resilient supporting unit interface; this two pressure transducer detects hydraulic bladder internal pressure in the elastomer of two ends respectively; and force value can be reacted to controller; when pressure surpasses certain value, implement alarm, when pressure oversteps the extreme limit pressure, implement the forced stoppage protection.The utility model is provided with limit positive stop at elastomeric limit position, increases the support stiffness of toggle when sensor or controller break down, and prevents excessively and reverses.The utility model can be monitored the elastomer stiffness variation at any time, the Security of better protection blower fan mechanical transmission, but Realtime Alerts alleviates guardian's work difficulty.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Figure 1-3, a kind of blower fan special intelligent type gear-box elastic support, comprise framework 1, be provided with two elastomers 4 up and down in the framework 1, be equipped with hydraulic bladder in two elastomers 4, the described hydraulic bladder outer end interface of two elastomers 4 up and down connects a pressure transducer 2 respectively, and described pressure transducer 2 links to each other with controller by circuit respectively.
The utility model can also the elastic extension extreme position of elastomer 4 be provided with limit positive stop 3 in framework.
During use, every covering device is made up of two the utility model, supporting two toggles of gear-box, every the utility model contains two elastomers 4 up and down, gear-box toggle one side upper end elastomeric hydraulic air bag connects (totally 2 hydraulic pressure connecting tubes 5) with opposite side toggle lower end elastomeric hydraulic air bag by hydraulic pressure connecting tube 5, elastomeric hydraulic air bag outer end interface up and down of the present utility model respectively is connected to a pressure transducer 2, this two pressure transducer detects hydraulic bladder internal pressure in the elastomer of two ends respectively, and force value can be reacted to controller, controller can give a warning and adjust the runnability of blower fan at any time according to the variation of pressure.When special circumstances occurring, limit positive stop 3 can increase the support rigidity of toggle, prevents and reverses.
