Utility model content
The purpose of this utility model is to provide a kind of solid of revolution to install manual lifting mechanism, to improve solid of revolution better installing hand-operated lifting effect, and convenient result of use as required.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of solid of revolution installs manual lifting mechanism, comprise the first guide holder and the second guide holder, first guide holder and second left and right sides, guide holder bottom are connected to the first Return spring and the second Return spring, first Return spring and the second Return spring bottom are all connected with fixed pedestal, first guide holder and second left and right sides, guide holder top are all connected with support column, first guide holder and the second guide holder bottom are provided with travelling nut, travelling nut centre position is provided with screw mandrel, be provided with shaft coupling on the right side of screw mandrel, on the left of screw mandrel, be provided with the first drive sprocket; Screw mandrel bottom is provided with speed reduction unit, is provided with the second drive sprocket on the left of speed reduction unit, and speed reduction unit front portion is provided with handwheel.
Enter plot, be provided with clutch shaft bearing seat on the left of the first guide holder, the second guide holder left and right sides is respectively arranged with the second bearing seat and the 3rd bearing seat, and clutch shaft bearing seat, the second bearing seat and the 3rd bearing seat centre position are provided with rolling bearing.
When this device specifically uses, between the first drive sprocket and the second drive sprocket, install chain.Handwheel is utilized to drive speed reduction unit work, speed reduction unit utilizes the first drive sprocket and the second drive sprocket to drive screw mandrel to rotate, screw mandrel drives travelling nut to move up and down, lifting inclined-plane on travelling nut contacts with the first guide holder and the second guide holder, the first guide holder and the second guide holder is impelled to move up and down, support column is moved up and down, completes lifting work.Screw mandrel and shaft coupling ensure the elevating mechanism synchronous operation of the left and right sides, the object increasing the first Return spring and the second Return spring is that after placing weight unloading, the gravity deficiency of support column and web joint thereof falls after rise to original position so that lifting next time to make it.
There is a belt pulley in this mechanism on the motor shaft of elevating mechanism, and coupler structure is processed in belt pulley front end, can be connected on a steering box, steering box one end axle connects a handwheel by shaft coupling, and handwheel is given prominence at instrument outside.At ordinary times the coupling rod between motor and steering box is taken off, when motor cannot work time, coupling rod is loaded onto, by rotating handwheel, then steering box turns to, and drives belt pulley to drive speed reduction unit again, and speed reduction unit drives transmission shaft to realize hand-operated lifting by sprocket wheel.Handwheel drives speed reduction unit work by connecting rod, speed reduction unit drives transmission shaft work, transmission shaft upper sprocket wheel and speed reduction unit upper sprocket wheel are by chain connection for transmission, two ends, transmission shaft left and right have bevel gear to be arranged in travelling nut to drive travelling nut to move up and down, lifting inclined-plane on travelling nut and guide holder linear contact lay, impel guide holder to move up and down, even if support column moves up and down, complete lifting work.Screw mandrel and shaft coupling ensure the elevating mechanism synchronous operation of the left and right sides, and four identical bearing seats guarantee lifting structure level, and lifting is consistent.Bearing seat, travelling nut, fixed pedestal, speed reduction unit are all fixed on the same plane of equipment, Return spring and fixed pedestal have 4 respectively, and every two Return springs are connected with the connection substrate of support column, and below is connected with fixed pedestal, they are identical material-structures, guarantee that pulling force is consistent; The object increasing Return spring is that after placing weight unloading, the gravity of support column and web joint thereof or insufficient pressure fall after rise to original position so that lifting next time to make it.
The beneficial effect of this utility model is: this mechanism effectively improves result of use, and hand-operated lifting when facilitating solid of revolution to install improves manufacturing effect, conveniently uses as required.
