A fully mechanized excavator secondary transportation overhead running device

Abstract

The invention relates to a fully-mechanized coal winning machine second-transport overhead operation device comprising a star-wheel loading mechanism, a transshipping mechanism, a motor unit, a hoist anchor pole, turn round wheels, a tunnel top plate and a steel wire rope; the star-wheel loading mechanism is arranged on the head of the fully-mechanized coal winning machine, and comprises a power device, a transmission device, a raking pawl mechanism and an unloading cylinder; the transshipping mechanism is used for transporting the unloading cylinder, and comprises a slewer, a track, a belt conveyor and a crawler belt walking device. A single bottom plate is omitted; the second-transport overhead operation device combines the top plate with the bottom plate, and the turn round wheels hang upside down to connect with the steel wire rope, thus forming the track; the transshipping mechanism is matched with the turn round wheels so as to reduce a belt move period in the second-transport device, thus improving an automation level; the second-transport overhead operation device is adapted to the conditions that ore rock geology is soft and water seepage phenomenon happens on ground; no derail rail-picking phenomenon is generated, and safety factor is relatively high.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an overhead running device for the second transport of a fully mechanized excavator. Background technique [0002] The construction methods of modern coal mine roadways at home and abroad mainly include drill and blast tunneling and comprehensive mechanized tunneling. Among them, coal and semi-coal rock roadways mainly use cantilever roadheader technology and equipment, which is the most common type of tunneling technology and equipment used in the field of coal mines at home and abroad, and it is also a rapid development in the 1970s and 1980s. The core equipment of advanced roadway excavation technology and equipment is fully mechanized excavator.

Problems solved by technology

[0003] Generally, when carrying out underground comprehensive mechanized excavation construction, a 22Kg / m temporary track is laid under the small sports car of the second transport of the fully mechanized excavator. Picking up the road is not safe and affects normal production

[0004] When the second transport trolley is in operation, because it often falls off the road, the whole transportation process needs to be supervised by a special person, which is extremely unsafe

[0005] Due to the fear of falling off the road, the comprehensive excavator needs to be particularly slow and stable when running back and forth, which seriously affects the working efficiency of the machine;

[0006] During the forward excavation process, after excavating to a certain distance, it is necessary to frequently drag the belt tail of the second transportation device, which affects the production efficiency

[0007] It can be seen that the traditional second transportation device using a single ground track is difficult to meet the needs of production, it is difficult to adapt to the special ground, and it seriously affects the production efficiency, and causes a huge waste of manpower and material resources
