Abstract

A plane fine-tuning device for a lifting stage comprises a worm gear mechanism, a housing and a base, wherein the worm of the worm gear mechanism is driven by a handwheel; the worm gear of the worm gear mechanism is arranged horizontally and matched with the worm; a screw rod arranged longitudinally penetrates the center of the worm gear; a threaded hole is formed in the center of the worm gear; the worm gear is in threaded connection with the screw rod; a hauling rope for hauling a stage body to move up and down is connected to the top of the screw rod; the housing adopts a box-shaped structure; the worm gear is arranged in the cavity of the housing and propped against the upper part in the housing; the screw rod penetrates the housing; a raised key is arranged on the housing; a key slot is formed in the screw rod; the raised key is arranged in the key slot; and the housing is fixedly connected with the stage body through the base. Being positioned by mistake, the table board of the stage can be lifted integrally through fine-tuning only by rotating the handwheel, so that the operation is simple and convenient.

Description

The plane micromatic setting of elevator stage

(1) technical field

The present invention relates to a kind of plane micromatic setting of elevator stage, belong to the stage machinery field.

(2) background technology

Be generally the table top fixed structure with apron, can not go up and down, this stage structure has certain limitation to layout, the performance of program, especially can't realize the stereoeffect of diversification.Along with improving constantly of the people's material and cultural life level, also increasingly high to the requirement of artistic grade, under the situation that stage layout art improves day by day; The stage 26S Proteasome Structure and Function also there has been the requirement of innovating, therefore, has developed elevator stage; This elevator stage goes up and down through the tractive of pull rope; Use a period of time rear haulage rope can produce extension and elongate, and causes stage table top location to compare desired location error to some extent, influences result of use.

(3) summary of the invention

The technical problem that the present invention will solve provides a kind of micromatic setting of elevator stage, need not to adjust pull rope, can realize the accurate location of stage table top.

For this reason, the present invention takes following technical scheme:

A kind of plane micromatic setting of elevator stage includes worm-and-wheel gear, housing and pedestal, and said worm screw is driven by handwheel, and said worm gear horizontal arrangement cooperates with worm screw; Said worm gear center is penetrated with the screw rod of vertical layout, and said worm gear center is provided with screwed hole, and said worm gear is connected with screw flight, and said screw rod top is connected with the pull rope that traction stage body goes up and down; Said housing is box structure; Said worm gear is positioned at said housing chamber, offsets with top in the housing, and said screw rod runs through said housing; Said housing is provided with protruding key; Said screw rod is provided with keyway, and the key of said convexity is arranged in the said keyway, and said housing is affixed through pedestal and stage body.

Said worm gear is fitted through the bottom surface of top in plane bearing and the housing.

The key of said convexity and said keyway are for being slidingly matched.

Operating principle of the present invention is: through operated by handwheel, drive worm-and-wheel gear work, because screw rod and worm gear adopt thread connecting mode; And screw rod has keyway, and the key affixed with case top matches, and having retrained screw rod can not rotate; Thereby can only order about worm gear moves up and down along screw rod; Because worm gear withstands housing, housing and stage table top are affixed, thereby have driven the up-down of stage table top.

Employing the present invention have the following advantages: when 1, site error appears in the stage table top, only needs, can realize the integral elevating fine setting of stage table top through rotating handwheel, and simple, convenient; 2, this main equipment of stage; Through the progressively adjustment of many pull ropes being realized the level requirement of stage table top,, adjust after the length fastening with 3 to 4 retainer clips because pull rope all is thicker wire quality; Operate very loaded down with trivial details; Precision also is not easy to reach, and this programme has not only alleviated labour intensity and simplified the fine setting operation of pull rope, and has significantly improved precision and efficient; 3, simple in structure, cost of manufacture is low, result of use good.

Fig. 2 is a sectional view of the present invention;

Fig. 3 is a vertical view of the present invention.

(5) specific embodiment

With reference to Fig. 1-3, a kind of plane micromatic setting of elevator stage includes worm-and-wheel gear, housing 1 and pedestal 2, and said worm screw 3 is driven by handwheel 4, and said worm gear 5 horizontal arrangement cooperate with worm screw; Said worm gear center is penetrated with the screw rod 6 of vertical layout, and said worm gear center is provided with screwed hole, and said worm gear is connected with screw flight, and said screw rod top is connected with the pull rope 8 that traction stage body 7 goes up and down; Said housing is box structure; Said worm gear is positioned at said housing chamber, offsets with top in the housing, and said screw rod runs through said housing; Said housing is provided with protruding key 10; Said screw rod is provided with keyway, and the key of said convexity is arranged in the said keyway, and said housing is affixed through pedestal and stage body.Said worm gear is fitted through the plane bearing 9 and the bottom surface of the interior top of housing.The key of said convexity and said keyway are for being slidingly matched.
