Lifting device with high safety performance for cargo loading and unloading

Abstract

The invention discloses a lifting device with high safety performance for cargo loading and unloading. The lifting device comprises a base, a lubricating mechanism and a placing mechanism, a support frame is arranged on the surface of the top end of the base, the support frame is movably connected with a threaded screw rod, a clamping device is arranged on the surface of one side of the threaded screw rod, and a sleeve is fixedly connected in the clamping device. Through the arranged piston barrel, the situation that when the sleeve slides on the threaded lead screw for a long time, the friction force of the contact face is increased, and the clamping device rotates on the threaded lead screw slowly after clamping cargo is effectively avoided, lubricating on the surface of the threaded lead screw is facilitated, the service life of the threaded lead screw and the sleeve is prolonged, the rotating effect of the threaded lead screw is guaranteed, the working efficiency of the lifting device is further improved, the situation that the lifting device does not provide space for placing parts is effectively avoided through the arranged placing groove, when the lifting device breaks down, the parts can be rapidly replaced, and the maintenance efficiency of the lifting device is improved.

Description

technical field [0001] The invention belongs to the technical field of cargo lifting devices, in particular to a lifting device with high safety performance for cargo loading and unloading. Background technique [0002] At present, tower cranes are generally used in domestic large-scale buildings, but simple lifting devices composed of motors, pulleys, etc. are generally used in rural buildings, and this device is relatively simple. [0003] However, there are still many disadvantages in the existing cargo lifting device. When the device is in use, the clamping device moves better on the threaded screw through the sleeve, but the sleeve moves on the threaded screw for a long time, and the friction of the contact surface increases. , so that the rotation becomes slow, and the device does not provide space for placing parts, so that the parts cannot be replaced quickly after the lifting device fails, which reduces the maintenance efficiency of the coating machine. Therefore, w...

Problems solved by technology

[0002] At present, tower cranes are generally used in large domestic buildings, but simple lifting devices composed of motors and pulleys are generally used in rural buildings, which are relatively simple.

[0003] However, there are still many disadvantages in the existing cargo lifting device. When the device is in use, the clamping device moves better on the threaded screw through the sleeve, but the sleeve moves on the threaded screw for a long time, and the friction of the contact surface increases. , so that the rotation becomes slow, and the device does not provide space for placing parts, so that the parts cannot be replaced quickly after the lifting device fails, which reduces the maintenance efficiency of the coating machine. Therefore, we propose a lifting device with high safety performance for cargo loading and unloading device
