Problems solved by technology

[0003] However, in small and medium-sized load-carrying screw elevators, when the motor fails or the power is cut off, the lifting part of the elevator will suddenly fall, which will cause a large impact force between the lifting part and the supporting part, which is easy to cause lifting. Partially damaged internally, which reduces the service life of the lift

Embodiment

[0022] Such as figure 1 with figure 2 As shown, the use method of the spiral lifting mechanism of the present invention includes the following steps, the screw mandrel 2 is rotated and installed in the lifting column 1, and the screw mandrel 2 is rotated under the drive of the driving mechanism to drive the rotating cylinder 4 on the screw mandrel 2 to rise or is to descend, and the chuck 7 connected to one end of the rotating cylinder 4 clamps the workpiece up or down; when rising, the thread 11 on the screw rod 2 is connected with the support block 9 on the inner wall of the rotating cylinder 4, and is located in the groove The roller 10 is in line contact with the upper surface of the thread 11. Since the support block 9 is distributed on the inner wall of the rotating cylinder 4 along the direction of rotation of the thread 11 on the screw 2, when the screw 2 rotates, the roller 10 moves upward along the upper surface of the thread 11. , to realize the upward movement of...

Abstract

The invention discloses a use method of a spiral lifting mechanism. A pilot sleeve can adjust stress at two ends of a rotating cylinder to be balanced, the breakage condition of the position where a chuck and the rotating cylinder are connected due to the fact that one end of the chuck is stressed excessively is prevented, when a motor fails, rollers can buffer instantaneous impact force between support blocks and threads, so that the damage degree of the rotating cylinder is reduced, and the stability of the lifting mechanism is improved.

Description

technical field [0001] The invention relates to a lift, in particular to a method for using a spiral lift mechanism. Background technique [0002] The traditional screw jack is generally composed of worm gear, box, bearing, screw and other parts; the working principle is: the motor or manual drive the worm to rotate, the worm drives the worm gear to decelerate the rotation, the inner cavity of the worm gear is processed into an internal thread, and drives the screw up and down Moving, due to the worm gear and worm inside, the deceleration effect of the lead screw achieves the effect of amplifying the thrust. As a kind of modern lifting equipment, the screw elevator has a wide range of applications, and the development of the screw elevator is also very rapid. It is not difficult to draw the development direction of the elevator in the future. Among them, the speed, variable speed and safety performance are the key points, and the importance of safety It is very important in...
