Abstract
The utility model provides a lifting device, which comprises a machine body, two same lead screws and two pairs of same worm wheels and worms, wherein the two same worms are parallel and are rotationally connected with the machine body; the two same worm wheels are matched with respective worms between the worms; the two same lead screws pass through the two same worm wheels and are connected; and the heads of the lead screws are provided with flange faying surfaces, and the tail parts of the lead screws are additionally provided with square slide blocks. The lifting device has the beneficial effects that by utilizing the same worm wheels and worms, the same lead screws and the same motor rate, synchronous lifting is achieved and a flat surface which is pressed down is smooth; by utilizing the slide blocks, the lead screws can be prevented from deflecting when moving; by utilizing the flange faying surfaces, the lifting device can be conveniently connected with other devices; and the lifting device has the advantages of simple structure, convenience in maintenance, low processing cost, high production efficiency and the like.
Description
Technical field
The utility model belongs to the elevator technology field, especially relates to a kind of lowering or hoisting gear.
Background technique
The application area of lowering or hoisting gear is quite extensive in existing technology, almost in the transmission system of various machinery, can see its trace.In different fields, lowering or hoisting gear also there is different requirement, all be the form of one group of worm and gear generally, there is the technical problem that flattens facial plane out-of-flatness, dismounting inconvenience up and down, is easy to generate rotation displacement in the lift on the production line of producing steel plate.
Summary of the invention
The problem that the utility model will solve provides a kind of lowering or hoisting gear, especially is fit to the device up-down that needs keep the certain level face, example: the lowering or hoisting gear of compressed steel plate up and down.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of lowering or hoisting gear; Comprise body, two identical screw mandrels and two pairs of identical worm and gears, said two pairs of identical worm and gears comprise the worm gear that two parallel and worm screws that be rotatably connected with body and two cooperate with separately worm screw between worm screw; Said two identical screw mandrels pass two identical worm gears and connection respectively, and lifting one's head has the screw mandrel of flange junction plane to be connected with body through guide sleeve.
Further, said screw mandrel afterbody has square slider.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; Identical worm and gear; Identical screw mandrel, identical motor speed has reached synchronization lifting and has made the plane of subduing smooth; Slide block can prevent that screw mandrel from having deflection when motion, have the flange junction plane conveniently to connect with other devices; Have simple in structurely, easy to maintenance, processing cost is low, the manufacturing efficiency advantages of higher.

Embodiment
As illustrated in fig. 1 and 2; The technological scheme of present embodiment is: a kind of lowering or hoisting gear; Comprise that body 1, two 2, two worm screws of identical screw mandrel 4 and two pairs of identical worm gears, 3 worm screws 2 are parallel and be rotatably connected that two worm gears 3 cooperate with separately worm screw 2 between worm screw 2 with body 1; Two identical screw mandrels 4 pass two identical worm gears 3 and connection, and lifting one's head has the screw mandrel of flange junction plane 4 to be connected with body 1 through guide sleeve 7.Further, said screw mandrel 4 afterbodys have square slider 6.
The working procedure of present embodiment: after the energising; Two identical motors drive 2 rotations of two identical worm screws with identical rotating speed, two identical worm screws 2 respectively with separately worm gear 3 engagements, thereby drive worm gear 3 rotations; Worm gear 3 drives screw mandrel 4 motions, realizes synchronization lifting.The square slider 6 of screw mandrel 4 afterbodys can prevent that screw mandrel 4 from having deflection, screw mandrel 4 to lift one's head and having the flange junction plane conveniently to connect with other devices when motion.Guide sleeve play the guiding role when screw mandrel moves
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (2)
1. lowering or hoisting gear; It is characterized in that: comprise body, two identical screw mandrels and two pairs of identical worm and gears, said two pairs of identical worm and gears comprise the worm gear that two parallel and worm screws that be rotatably connected with body and two cooperate with separately worm screw between worm screw;
Said two identical screw mandrels pass two identical worm gears and connection respectively, and lifting one's head has the screw mandrel of flange junction plane to be connected with body through guide sleeve.
