Electromagnetic-damping-principle-based industrial engineering transportation lifting machine protection rotating shaft

Abstract

The invention relates to the technical field of industrial engineering transportation, and discloses an electromagnetic-damping-principle-based industrial engineering transportation lifting machine protection rotating shaft. The electromagnetic-damping-principle-based industrial engineering transportation lifting machine protection rotating shaft comprises a shell, wherein the front surface of the shell is fixedly connected with a magnetic ring, the inner wall of the middle portion of the magnetic ring is movably connected with a rotating shaft, and electric push rods are fixedly connected with the inner wall of the middle portion of the rotating shaft. According to the electromagnetic-damping-principle-based industrial engineering transportation lifting machine protection rotating shaft, centrifugal blocks are driven to move through the rotating shaft, the centrifugal blocks drive dielectric plates to move, then a speed reduction effect is achieved through cooperative use of reset springs and negative plates, at the moment, a coil is in a completely-closed state, magnetic poles of the coil and the magnetic ring generate motion of cutting magnetic induction lines, due to the fact that magnetic flux penetrated by the coil changes, the coil generates induction current, and a magnetic field generated by the current can hinder relative motion of the rotating shaft, so that the purpose of reducing the speed of the rotating shaft is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial engineering transportation, in particular to a hoist protection shaft for industrial engineering transportation based on the principle of electromagnetic damping. Background technique [0002] In modern engineering, it is necessary to apply the content of industrial engineering to optimize various engineering operations. In industrial engineering operations such as conveying materials, lifting devices are often used. The winch of the existing lifting device is generally made of an electric motor. Driven by the power source, the material is lifted and lifted. However, the existing lifting equipment does not have protective devices, which can easily cause safety accidents. [0003] Due to the single power of the existing lifting device, there will be insufficient power during hoisting, which will affect the transportation of materials. The sling on the rotating shaft is relatively unstable in op...

Problems solved by technology

[0006]Aiming at the deficiencies in the prior art, the present invention provides a hoist protection shaft for industrial engineering transportation based on the principle of electromagnetic damping, which has simple operation and real-time limit for the hoist shaft. The advantages of speed protection and emergency braking solve the problem that traditional equipment does not have speed limit protection, which makes the hanging rope fall off and cause the material to fall.
