AI Technical Summary

Technical Problem

The crane's auxiliary arm is inefficient during the deployment and retraction process, and the operator needs to manually operate the pin, resulting in high labor intensity and low efficiency.

Method used

A plug-in and unplugging pin device is designed, including a base, a driving member and a first pin shaft. The base is installed on the main arm. The extending shaft of the driving member is connected to the first pin shaft. It is automatically inserted or retracted by the extension or retraction of the driving member. Pull out the first pin hole to achieve rapid expansion and retraction of the auxiliary arm.

Benefits of technology

It greatly improves the expansion and recovery efficiency of the auxiliary arm, reduces the need for manual operation by the operator, reduces the labor intensity, and ensures the normal rotation and placement of the auxiliary arm.

Abstract

The invention discloses a pin inserting and pulling device and a crane, and relates to the technical field of pin inserting and pulling device.The pin inserting and pulling device is used for inserting or pulling out a pin shaft between an auxiliary arm of the crane and a main arm of the crane, the auxiliary arm is provided with a connecting plate, the connecting plate is provided with a first pin shaft hole, and the pin inserting and pulling device comprises the first pin shaft, a base and a driving component; the base is used for being installed on the main arm, the driving component is installed on the base, and an extending shaft of the driving component is connected with the first pin shaft and extends out or retracts back to drive the first pin shaft to be inserted into or pulled out of the first pin shaft hole. According to the pin inserting and pulling device, the first pin shaft is controlled to be inserted into or pulled out of the first pin shaft hole through the driving component, so that the pulling or inserting efficiency of the first pin shaft is greatly improved, the unfolding or folding efficiency of the fly jib is greatly improved, an operator does not need to manually pull out or insert the first pin shaft, and the labor intensity of the operator is also reduced.
