Distance detecting mechanism for measuring lifting distance of hoisting device

Abstract

The invention discloses a distance detecting mechanism for measuring lifting distance of a hoisting device. The mechanism comprises a driving wheel which is propped to a hoisting rope, a gear countingpart, and a transmission gear assembly which is mounted between the driving wheel and the gear counting part, wherein the gear counting part is provided with multi-stage counting gear assemblies which are sequentially engaged based on a preset transmission route; each of a driving shaft and a driven shaft of the counting gear assembly at each stage is fixedly provided with a counting plate; a counting plate on each driven shaft rotates by a preset angle as the counting plate on the corresponding driving shaft rotates by a circle, and thus all counting plates can record the number of rotatingcircles of the driving wheels on the preset transmission route in a scale mode; the hoisting rope is pulled to drive the driving wheel to rotate, and the rotating driving wheel drives a transmission gear assembly to rotate, and finally the transmission gear assembly drives the engaged gear counting part to rotate. When in hoisting, the lifting distance of the hoisting rope can be accurately calculated without excessive workers, and thus the lifting distance of the hoisting rope can be conveniently accurately acquired.

Description

technical field [0001] The invention relates to the field of hoisting, in particular to a distance detection mechanism for measuring the hoisting distance of hoisting equipment. Background technique [0002] Common hoisting equipment includes pulley assemblies, cranes, electric hoists, etc. These hoisting equipment mostly use slings to lift goods to realize cargo transfer. In some usage occasions, considering the cost and working environment, the staff needs to use the pulley assembly to manually lift the goods. Generally, the staff usually holds one end of the sling, and pulls the goods tied at the other end of the sling by means of the pulley assembly wound by the sling, so that the goods can be raised and lowered in the hoisting passage. [0003] In some occasions, due to the large volume of the cargo or the narrowness of the hoisting channel, the operator standing on the top of the hoisting channel cannot accurately know the lifting distance of the cargo with reference ...

AI Technical Summary

Problems solved by technology

However, this hoisting method involves a large number of personnel, and it is difficult to accurately obtain the lifting distance of the cargo with the naked eye
