Stepping crossing vehicle

Abstract

The invention relates to the field of mechanical equipment of tunnel kiln machinery, in particular to a stepping crossing vehicle. The stepping crossing vehicle comprises a rack; a driving mechanism is arranged at the rear end of the rack and is connected with driving rollers; driven rollers are arranged at the front ends of the driving rollers; a support is arranged at the front end of the rack; pulleys are arranged in the middle of the support; hydraulic cylinders are arranged at the lower ends of the pulleys respectively; push plate frames are arranged at the upper parts of the pulleys and are hinged to push plates; proximity sensors are arranged at two ends of the hydraulic cylinders; a console and a hydraulic station are arranged at the rail of the rack; the hydraulic station is connected with a positioning hydraulic cylinder arranged in the middle of the tail of the rack; the positioning hydraulic cylinder is connected with positioning pins at left and right ends of the tail of the rack by support rods. According to the stepping crossing vehicle, the safety, stability and automation of the crossing vehicle are improved, waste of manpower and time is reduced, and the work efficiency is improved. A smooth, reliable and convenient action process is realized in a kiln conveying process and a hill foot road changing process.

Description

(1) Technical field [0001] The invention relates to the field of mechanical equipment for tunnel kilns, in particular to a walking trolley. (2) Background technology [0002] Kiln cars and drying cars are the vehicles used in the brick industry to carry bricks and transport them into sintering and drying facilities. In the past, they relied on manual work, but now they can use stacking machinery to stack the finished bricks in layers according to a certain structure. When the kiln car is used in conjunction with the automatic stacking equipment, it needs to reach the designated position accurately, and it needs to move reciprocatingly and in multiple positions according to the stacking method during the stacking process. In the process of kiln car lane change in the past, the use of ordinary wagons was realized by relying on the built-in or external hoist to drag the kiln car, which mainly has the following disadvantages: 1. The ordinary wagon is unstable and difficult to co...

AI Technical Summary

Problems solved by technology

In the past kiln car lane change process, the use of ordinary ferry cars is achieved by relying on the built-in or external hoist to drag the kiln car, which mainly has the following disadvantages: 1. The ordinary ferry car is unstable and difficult to control; 2. The process It is complex and requires the cooperation of multiple people to operate and the work efficiency is low; 3. There are great safety hazards in the use of the hoist; 4. The kiln car is not accurate and not easy to fix on the ferry car, and it is very easy to drop the car
