Abstract
The utility model discloses a shovel plate groove side, a scraper conveyor and a coal mining system. The shovel plate groove side comprises a shovel plate base body and an abrasion resistance steel plate fixed on the shovel plate base body. At least a part of the shovel plate surface of the shovel plate groove side is formed by the upper surface of the abrasion resistance steel plate. The shovel plate groove side is capable of not only guaranteeing overall mechanical properties of the shovel plate groove side, meeting requirements of coal mining operation, but also reducing rate of wear of the shovel plate surface, prolonging maintenance period of the shovel plate groove side, and reducing maintenance cost caused by abrasion of the shovel plate surface. When the abrasion resistance steel plate is incapable of effectively supporting support sliding boots of a coal mining machine due to serious abrasion, the abrasion resistance steel plate is capable of being separated from the shovel plate base body, the abraded abrasion resistance steel plate is replaced by another abrasion resistance steel plate, and the maintenance cost caused by the abrasion of the shovel plate surface is reduced to the greater extent.
Description
Technical field
The utility model relates to a kind of coal excavation apparatus, and particularly a kind of shovel board ledge, also relate to a kind of slat conveyer that comprises this shovel board ledge, also relates to a kind of coal mining system that comprises this slat conveyer.
Background technology
Current, usually utilize to comprise that the coal mining system of slat conveyer and flitting carries out coal mining activity.Wherein, slat conveyer comprises the more piece intermediate channel, and intermediate channel generally comprises baffle, shovel board ledge and middle plate, base plate.The front of middle plate and base plate all is connected with the shovel board ledge, and the back of middle plate and base plate all is connected with baffle, and then forms intermediate channel between baffle and shovel board ledge.The traction track of coalcutter is installed on baffle; The shovel board ledge comprises ledge body and the shovel board of stretching out forward from the front side of ledge body, and the shovel board upper surface forms the shovel board face.The rear portion of the tractive unit of flitting has the trailer coupling that matches with traction track; Trailer coupling can be traction wheel, and traction track can be the pin rail that coordinates with driving chain sprocket.The front portion of tractive unit is provided with the support piston shoes, supports piston shoes and is supported on the shovel board face.Based on the abominable especially working environment of coal mining activity, support between piston shoes and shovel board face and form bearing fit; Like this, slat conveyer has just formed the walking track of flitting, and is the stable basis that provides support of flitting.
When carrying out coal mining activity, trailer coupling coordinates with traction track, and the head roll coalcutter moves with respect to slat conveyer, simultaneously, support piston shoes with respect to shovel board towards left or right slip, carry out the cut coal seam on driving surface.The shovel board face will bear on the one hand and support piston shoes to its vertical load that applies, and will bear simultaneously and support piston shoes to the sliding load of shovel board face, and this makes shovel board surface wear speed very fast.
If in order to reduce the rate of wear of shovel board face, just need to increase the wear resisting property of shovel board, increase the shovel board wear resisting property and can utilize the higher high-abrasive material of hardness to make shovel board; Based on the slat conveyer need of work, guarantee the bulk strength of shovel board ledge, just need to make the shovel board ledge with the higher high-abrasive material of hardness.But make with the higher high-abrasive material of hardness the formation that the shovel board ledge will affect the shovel board ledge, reduce the toughness of shovel board ledge, the endurance life of shovel board ledge is reduced, cause the overall mechanical properties of shovel board ledge can't satisfy the needs of coal mining activity.Therefore, generally keep shovel board ledge overall mechanical properties by sacrificing wear resisting property at present, like this, in use, just need to be by the shovel board ledge be carried out continuous maintenance or periodic replacement, to keep the normal operation of slat conveyer; And then this just causes the maintenance cost of slat conveyer higher.
Therefore, how reducing the maintenance cost that the shovel board surface wear due to the shovel board ledge produces is the technical barrier that current those skilled in the art need to solve.
