Description
Technical field
What the present invention relates to is a kind of braking device that plays the safety protection effect of technical field of engineering machinery, specifically is a kind of dead electricity servo stabiliser that is applied on the window cleaning equipment travelling mechanism.
Background technique
Along with rapid economic development of China in recent years, the popularization of its engineering machinery also changes independent research into gradually by relying on external import fully in early days, and every index of many products has all reached external advanced level, some engineering equipment performance even surpassed external top technical merit.But China does not have the real Hesperian industrial revolution that lives through after all, though some has formed the engineering machinery series of own characteristic product is arranged, but most of products are all still quoted the early stage technology of the Soviet Union, especially in the hoist series products, innovation of not controlling oneself basically and research and development, be subjected to the influence on development of Chinese architecture industry, the development of window cleaning equipment delays major step especially and cuts down on world arena.At present; the window cleaning equipment travelling mechanism aspect stopping brake the method for normal employing be to use rail clamping device; though rail clamping device can make equipment and track that slide relative does not take place; but its operability is more loaded down with trivial details; and its reliability is low; the effective resistance that produces is little, slides easily when applied external force is big, and its maximum shortcoming is general and can carries out manually fastening when shutting down.
Find that through retrieval the kind of break is a lot of at present, but these breaks are mainly used to stop the suspention article to fall or rotatablely move to prior art.For example click stopper, electromagnetic brake, hydraulic push-rod brake or the like, as break, this series products only can make to rotatablely move and stop, and but can not be applied on all kinds of trolley travellings.I take charge of the needs according to actual engineering, the spy has researched and developed a kind of dead electricity servo stabiliser that can be applicable in the operation, it has solved the hidden danger that the window cleaning equipment after the dead electricity continues to slide effectively, and it also is to the other direction development on braking principle, promptly utilizes the eccentric wheel self-lock mechanism.
Summary of the invention
Because the shortcoming of aforementioned prior art, the present invention is directed to the actual demand of present engineering, a kind of dead electricity servo stabiliser that is applied on the window cleaning equipment travelling mechanism is provided, especially under situation about having on the track on slope, can effectively prevents the downslide of window cleaning equipment after outage.
In order to reach the foregoing invention purpose, a kind of dead electricity servo stabiliser of the present invention comprises: electric pushrod, reach, positioning spacer, bearing wheels, the location jackscrew, eccentric wheel, thrust spring, horizontal guide sheave, support body, the friction brake slipper, belleville spring, wherein: described electric pushrod is fixed on the support body, reach is lived on the electric pushrod crown, positioning spacer is enclosed within on the reach, bearing wheels is connected on the positioning spacer, the location jackscrew is fixed on the support body, the head of location jackscrew withstands eccentric breach, thrust spring is enclosed within on the reach, one end of thrust spring withstands support body, eccentric wheel is withstood in the other end, horizontal guide sheave is fixed on the friction brake slipper, the friction brake slipper is connected on the support body, and belleville spring is connected in support body two end slots and with swing bolt and fixes.
Further, described reach comprises thrust bearing pin, adjusting screw, Fixed latches, slip copper sheathing, hollow shaft, thrust copper sheathing, described thrust bearing pin is connected in the hollow shaft, and adjusting screw is fixed on the thrust bearing pin, and Fixed latches passes slip copper sheathing and thrust copper sheathing.When promoting the axle slide relative, can drive the relative hollow shaft of slip copper sheathing and thrust copper sheathing and slide.
Further, described bearing wheels is a hollow wheels, and a circle of bearing wheels is equipped with tapped hole, and hexagon socket cap head screw is installed, and described hexagon socket cap head screw head has and is screwed on a small quantity in the described tapped hole.
Further, described location jackscrew comprises nut, screw tap, silk head, spring, steel ball, the fastening silk of described nut head, and the screw tap fixing spring, spring withstands steel ball, and steel ball can move in the silk head.
Further, described eccentric wheel is a wheel hub with eccentric opening, and its inside is provided with some lightening holes and bent moon hole, and is fixed with balancing weight on it and makes the eccentric wheel barycenter remain on the eccentric opening center substantially.
The present invention carries out work in the following manner: this dead electricity servo stabiliser two ends are connected on the underframe of window cleaning equipment, when the window cleaning equipment travelling mechanism is powered, give the power supply of dead electricity servo stabiliser electric pushrod simultaneously, electric pushrod promotes the thrust bearing pin in the reach, the thrust bearing pin promotes the thrust copper sheathing, promote eccentric wheel simultaneously, therefore eccentric wheel separates with bearing wheels, it is the bent moon hole on the hexagon socket countersunk flat cap head screw disengagement eccentric wheel on the bearing wheels, because the location jackscrew withstands the breach on the eccentric wheel, therefore eccentric wheel can not rotate because of vibration or inertial force, this moment the dead electricity servo stabiliser we be referred to as open mode, promptly produce the locking braking.When the window cleaning equipment operation does not have electricity, the dead electricity servo stabiliser does not have yet simultaneously, electric pushrod withdrawal this moment, owing to clamp a thrust spring between eccentric wheel and the wheel carrier, therefore under the effect of thrust spring, eccentric wheel is pushed to bearing wheels, in the hexagon socket countersunk flat cap head screw on the while bearing wheels packs into eccentric bent moon hole, when window cleaning equipment generation slide relative, because bearing wheels will be rotated further, rotate thereby drive eccentric wheel, when eccentric wheel turns over several angle, variable height will take place in its dead electricity servo stabiliser integral body, when the wearing piece on the friction brake slipper contacts with track, to produce friction, during less than track rail level friction ractor, will produce locking phenomenon according to the tangent value of eccentric angle of friction.Therefore no matter window cleaning equipment is much along the inclined-plane sliding force, can both rely on eccentric friction to stop its downslide.After window cleaning equipment produces braking because of downslide, need manually reset.
Because the present invention adopts eccentric wheel angle of friction self-lock mechanism to brake, so its self-locking reliability, highly sensitive, solved the braking problem of window cleaning equipment aspect operation effectively, the present invention have novel structure, simple to operate, structural configuration is compact, advantage such as safe and reliable.
