Description

Clamping device for lifting mechanism

Technical Field

The utility model relates to the technical field of lifting external loads, in particular to a clamping device for a lifting mechanism.

Background

Many existing devices are fixed in the air, and such devices are generally equipped with a lifting mechanism to lift the devices, so as to achieve the purpose of maintenance, replacement or operation. In such liftable devices, a rope is often used for traction and is fixed in the air. However, as the rope ages or wears during lifting, the rope can break, so that the equipment falls from high altitude, the equipment is damaged, and bottom personnel are easy to injure and die. Therefore, after the equipment rises to the set height, the equipment is fixed by the clamping device, so that the stress of the rope is avoided, and the situation can be avoided to the greatest extent.

However, the conventional clamping device has a complex structure, a large volume and is not attractive when being installed at high altitude, so that a clamping device with a small volume is needed in the field.
