AI Technical Summary

Technical Problem

Existing aircraft ladder towing equipment suffers from insufficient traction of the towing vehicle, making it difficult for the towing vehicle to turn around when pulling the aircraft ladder and causing inconvenience in use.

Method used

A lifting mechanism is installed on the top of the tractor body. A buffer mechanism and a support platform are installed on the top of the lifting mechanism. A clamping mechanism is installed on the support platform. The support platform is driven to move upward by a cylinder to contact the aircraft ladder crossbeam. The buffer mechanism is used to improve the grip, and the clamping mechanism is driven by a rack and pinion to automatically clamp the aircraft ladder crossbeam.

Benefits of technology

It improved the traction of the tractor, enabling stable traction and easy turning of the aircraft ladder, and enhanced the ease of operation of the tractor.

Abstract

The application provides an aircraft ladder frame traction device and a traction method, and belongs to the technical field of traction devices. The aircraft ladder frame traction device comprises a traction vehicle body, and a lifting mechanism is installed on the top of the traction vehicle body. By installing the lifting mechanism on the top of the traction vehicle body and installing the buffer mechanism on the top of the lifting mechanism, the support table is installed on the top of the buffer mechanism, and then the traction vehicle body is moved to below the aircraft ladder frame cross beam, the lifting mechanism drives the support table to move upward, so that the support table is in contact with the bottom of the aircraft ladder frame cross beam, the aircraft ladder frame cross beam extrudes the support table downward, and then the buffer mechanism is compressed, so that the downward pressure is applied to the traction vehicle body, and the ground holding capacity is improved. In addition, the rack is installed on the top of the lifting mechanism, the clamping mechanism is installed on the top of the support table, when the support table moves downward, the rack drives the clamping mechanism to move, so that the aircraft ladder frame cross beam is automatically clamped and fixed, and the use is convenient.
