Technical field
The utility model relates to a kind of jacking system, especially relates to a kind of elevator.
Background technology
The worm gear screw lift is widely used in the platform that all kinds of needs move up and down, as corridor of stage, large-scale passenger steamer etc., at present, domestic worm gear screw lift adopts worm and gear to slow down, make screw mandrel carry out fore and aft motion by the Acme thread transmission between worm gear and the screw mandrel then, promote the Platform Implementation flat-bed and move up and down.Chinese patent discloses a kind of pilot bar lifting mechanism (Granted publication number: CN201686441U), it mainly comprises frame, motor, transmission device, screw mandrel, feed screw nut, motor is connected with screw mandrel by transmission device, feed screw nut and screw mandrel are connected, on the feed screw nut, be fixed with the lifting adapter plate, be fixed with lifting bar on the lifting adapter plate, the lifting bar upper end is fixedly connected with lifting table; Frame is provided with orienting sleeve, and lifting bar passes orienting sleeve and forms sliding pair with it; Be fixed with pilot bar in frame, and pilot bar pass the lifting adapter plate and with its composition sliding pair; The lifting adapter plate is provided with three lifting bars, and three lifting bar triangularities are arranged on around the pilot bar; Be connected by linear bearing between pilot bar and the lifting adapter plate, be connected by linear bearing between lifting bar and the orienting sleeve; Frame is provided with the photoelectric switch that cooperates with the lifting adapter plate.But the structure of this elevator is comparatively complicated, and manufacturing cost is higher, and can only carry out dipping and heaving in certain scope, can't regulate range as required.
The utility model content
The utility model provides a kind of elevator, and it mainly is that to solve the structure of existing in prior technology elevator comparatively complicated, and manufacturing cost is higher, and can only carry out dipping and heaving in certain scope, can't regulate range as required.Deng technical matters.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of elevator of the present utility model comprises base, is fixed with interior guard shield on the described base, and interior guard shield upper end is fixed with the feed screw nut, and feed screw nut's internal whorl is connected with screw mandrel, and the screw mandrel upper end is connected with reductor by flat key, and reductor connects motor.Base can fix on the ground, behind the electric motor starting, can give screw mandrel by the reductor transmission with power, and after the screw mandrel rotation, the effect by the feed screw nut can be so that screw mandrel rises gradually, thereby whole elevator can be with the article upward movement.
As preferably, be fixed with back-up ring by attaching parts on the described screw mandrel, back-up ring is located at the upper surface of reductor.The screw mandrel upper end can be connected with reductor by flat key, and back-up ring can be fixed reductor.
As preferably, be fixed with upper junction plate by attaching parts below the described reductor, the lower surface of upper junction plate is fixed with lower connecting plate by attaching parts.Reductor can be fixed on the motor by attaching parts, thereby make that assembling is comparatively simple.
As preferably, described in guard shield be provided with outer shield outward, be provided with bearing between outer shield upper end and the lower connecting plate.Outer shield can prevent that dust and other impurities from entering between screw mandrel and the interior guard shield, makes that the service life of elevator is longer, and bearing can be so that screw mandrel be more smooth and easy rotatably.
As preferably, described outer shield outside face is fixed with adapter plate.Adapter plate can be used for fixing with other article.
As preferably, be provided with floor between described adapter plate and the outer shield.Floor can play the effect of strengthening intensity, makes adapter plate be not easy fracture when bearing article.
As preferably, described base cross-under has adjustment hole in interior guard shield inside on base, the interior guard shield, and cross-under has the base plate locking pin in the adjustment hole.Interior guard shield can be at base adjusted height, thereby therefore the range that can regulate whole elevator can make the Applicable scope of elevator wider.
Therefore, structure of the present utility model and assembling are all comparatively simple, and manufacturing cost is lower, and by adjustable base, can carry out dipping and heaving in certain scope, can arbitrarily regulate range as required, and Applicable scope is wider.
