Turning belt conveyor

Abstract

The invention discloses a turning belt conveyor used for loading and unloading cargoes of a wagon. The turning belt conveyor comprises an engine base, a base plate rotary table, a lower rotary table, an upper rotary table, a belt conveyor and an electric control system, wherein the engine base comprises a base plate, wheels and hoisting supporting legs; a retractable arm is mounted on the base plate rotary table; the retractable arm is composed of a square outer sleeve, a square inner sleeve and a first hydraulic cylinder; the outer end of the square inner sleeve is fixedly connected with the lower part of a vertical shaft; the horizontal part of the lower rotary table is connected with the middle part of the vertical shaft by a rotary support; the inner end of the upper rotary table is connected with the upper part of the vertical shaft by a rotary support; the belt conveyor is composed of a retractable feeding belt conveyor and a retractable discharging belt conveyor. The turning belt conveyor disclosed by the invention only adopts the retractable feeding belt conveyor or the retractable discharging belt conveyor so that the turning loading and unloading of the cargoes of the wagon can be realized; the operation is convenient, and the cargoes can be more smoothly and safely conveyed. The turning belt conveyor disclosed by the invention has a smaller volume and is more flexible to move on a freight transport warehouse platform.

Description

technical field [0001] The invention relates to a curved belt conveyor used for loading and unloading goods on railway wagons. Background technique [0002] The efficiency and safety of the loading and unloading of railway packaged goods are more concerned issues in the industry. Due to the low efficiency of manual loading and unloading, high labor intensity, and easy damage to the goods, the industry tends to use machines to load and unload goods. The Chinese utility model patent with the authorized announcement number CN203558586U published on April 23, 2014 discloses a turning conveyor loading and unloading machine. The belt conveyor is used to realize the turning conveying and loading and unloading of goods. Although this turning conveyor loading and unloading machine can realize the function of turning conveyor loading and unloading, due to the use of three belt conveyors, the volume is large, the structure is more complicated, and the operation is cumbersome. The go...

AI Technical Summary

Problems solved by technology

Although this kind of turning conveyor loading and unloading machine can realize the function of turning conveyor loading and unloading, but because of the use of three belt conveyors, the volume is large, the structure is relatively complicated, and the operation is troublesome.

The goods on the belt conveyor need to be transferred from the feed belt conveyor to the transition belt conveyor, and from the transition belt conveyor to the discharge belt conveyor, which may easily cause the goods to be stuck or fall during transportation.

This kind of turning conveyor handling machine, if the three belt conveyors are arranged in a straight line, the length is too long, and if they are folded and arranged, the width is too wide, which makes the turning conveyor handling machine not flexible enough when moving on the freight storage platform.
