[0015] The present invention provides a lifting device and locking method for mechanical engineering, which have the following beneficial effects compared with the prior art: 1. The lifting device of this mechanical engineering inserts one end of the cylindrical mechanical part into the slot of the locking card seat. Under the action of the magnetic ring, the locking card seat and the cylindrical mechanical part are initially fixed. The motor drives the transmission gear to rotate, and the transmission gear drives the rotating gear plate to rotate. The rotating gear plate drives multiple clamping screw sleeves to rotate synchronously through the bevel gear. Under the action of the thread, one end of the clamping screw moves into the slot, and the clamping screw drives the arc clamping plate to move, so that the arc clamping plate fits with both sides of the cylindrical mechanical part, so that the cylindrical mechanical part can be further fixed inside the locking card seat.

[0016] 2. In the lifting device of this kind of mechanical engineering, when the cylindrical mechanical part is inserted into the slot, one end of the cylindrical mechanical part fits with the fixed suction cup, and under the action of the fixed suction cup, the cylindrical mechanical part and the locking socket can be further locked. When the cylindrical mechanical part is pulled out, the electromagnetic block is energized to generate magnetic force, and the movable iron block moves inside the installation slot under the action of the magnetic force. The movable iron block drives the movable card block to move through the movable rod, so that one end of the movable card block is separated from the vent, and air can enter the air cavity through the air inlet, and enter between the fixed suction cup and the cylindrical mechanical part through the vent, so that the fixed suction cup can be separated from the cylindrical mechanical part.

[0017] 3. When lifting a cylindrical mechanical part with different diameters at both ends of the lifting device of this mechanical engineering, the two locking sockets are subjected to different weights. The user can adjust the weight of the water inside the sink to make the weight of the two locking sockets the same, so that the cylindrical mechanical part can be lifted smoothly.

[0018] 4. The lifting device of this mechanical engineering can facilitate the movement of the counterweight base and the movement of the entire device through the action of the moving wheel. When it is moved to the use place, the user drives the rotating ring seat to rotate through the convex block, and the rotating ring seat drives multiple rotating screw sleeves to rotate synchronously through the rotating gear. Under the action of the thread, the fixing screw moves downward with the rotation of the rotating screw sleeve, and the fixing screw drives the square block to move downward, and the square block drives the limiting tooth block to move downward, so that the limiting tooth block is inserted into the inside of the annular groove and is engaged with the limiting tooth ring, so that the moving wheel cannot rotate, thereby making the counterweight base unable to move, which is beneficial to the use of the overall device. When the fixing screw moves downward, the fixing screw can move downward through the movable plate, the movable plate drives the pressure rod to move downward, and the pressure rod drives the support ring to move downward. When the limiting tooth block is engaged with the limiting tooth ring, the support ring fits with the ground, which can strengthen the contact between the counterweight base and the ground, and strengthen the support and limit of the counterweight base.

[0019] 5. In this type of mechanical engineering lifting device, when the counterweight base is fixed on the ground, water enters the counterweight water tank through the water inlet pipe, which can increase the weight of the counterweight base, prevent the device from tilting during lifting, and enhance the lifting effect. The user pushes the adjusting ring downward, and the adjusting ring drives the adjusting plate to move downward through the slider, and the adjusting plate drives the adjusting rod to move downward, and the adjusting rod drives the sealing block to move downward, and the sealing block drives the movable block to move through the push rod, compressing the first support spring, and the sealing block is separated from the sealing ring, so that the water inside the counterweight water tank can be discharged, which is convenient for reducing the weight of the counterweight base and facilitating the movement of the entire device.
