Cable anti-separating clamping device with directly-proportional clamping force and pulling force

Abstract

The invention discloses a cable anti-separating clamping device with directly-proportional clamping force and pulling force. The cable anti-separating clamping device with the directly-proportional clamping force and pulling force comprises six location seats, wherein a rack is movably connected to the inner side of each location seat; a fixed rod is movably connected between each two location seats; an adjustment bolt is movably connected to the outer side of each location seat; six clamping mechanisms are movably connected among the six location seats; a rotary wheel is movably connected between each two adjacent clamping mechanisms; and a clamping block and a tooth are fixedly connected to the surface of each rotary wheel. According to the cable anti-separating clamping device with the directly-proportional clamping force and pulling force, the dimensions of the middle part of each clamping block are greater than the dimensions of the two ends of the clamping block and each clamping block is fixedly connected with the corresponding rotary wheel, each clamping block and the corresponding rotary wheel start to rotate along with the increasing of the pulling force of a cable, and the distances among the clamping blocks is reduced, so that stability during the clamping of the device is ensured; and meanwhile, the distances among the clamping blocks is reduced along with the increasing of the pulling force, and the clamping blocks are made to always clamp the cable, so that the purpose of the directly-proportional clamping force and pulling force of the device is realized.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an anti-off clamping device for cables whose clamping force is proportional to the pulling force. Background technique [0002] In the process of mechanical manufacturing, it is often necessary to use cables to hoist and transport workpieces. For large workpieces, cranes are generally used for hoisting. Due to the limited travel of the crane, workpieces that exceed the stroke are generally fixed with cables and then clamped. Clamp the cable and carry it by a forklift or manually. Since the weight of the workpiece is generally large, that is, the tension on the cable is relatively large. The clamping device uses its own clamping force to clamp the cable. When the tensile force on the cable is less than the clip When the clamping force provided by the clamping device, the normal lifting process can be carried out. When the workpiece is hoisted, it is affected by its ow...

[0002] In the process of mechanical manufacturing, it is often necessary to use cables to hoist and transport workpieces. For large workpieces, cranes are generally used for hoisting. Due to the limited travel of the crane, workpieces that exceed the stroke are generally fixed with cables and then clamped. Clamp the cable and carry it by a forklift or manually. Since the weight of the workpiece is generally large, that is, the tension on the cable is relatively large. The clamping device uses its own clamping force to clamp the cable. When the tensile force on the cable is less than the clip When the clamping force provided by the clamping device, the normal lifting process can be carried out. When the workpiece is hoisted, it is affected by its own gravity and the swing of the workpiece. At this time, the tension on the cable increases. When the pulling force exceeds the clamping provided by the clamping device When the force is applied, the cable may fall off, which poses a certain safety hazard
