According to the lifting device of the fully mechanized coal mining face scraper conveyer, the piston rod of the lifting cylinder is controlled by the hydraulic system of the hydraulic support to stretch and retract so that the purpose that the scraper conveyer is lifted can be achieved.
Description
Technical field
The utility model relates to the comprehensive mechanical coal mining apparatus field, relates in particular to a kind of fully-mechanized mining working surface conveyer lifting appliance.
Background technology
At present, comprehensive mechanical coal mining equipment mainly contains hydraulic support, drag conveyor and coal-winning machine.The lifting of fully-mechanized mining working surface conveyer (being commonly called as scraper-trough conveyer) is mainly to stay 150mm with interior ground coal while relying on coal mining machine roller cutting rib, and pushing and sliding cylinder by hydraulic support is used for realization.Running into the tomography drag conveyor needs to promote, can only the rib side go the cushioning height at 150mm with interior filler.This kind of method is longer with the time, poor practicability, and danger is larger, is unfavorable for that personal security and work plane are fast by geological structures such as tomographies and may endanger coal-winning machine.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of and can facilitate, the fully-mechanized mining working surface conveyer lifting appliance of the lifting drag conveyor of safety.
For the technical scheme that addresses the above problem employing is: fully-mechanized mining working surface conveyer lifting appliance comprises hydraulic support, lift cylinder and the drag conveyor connector with back timber and hydraulic system, lift cylinder comprises cylinder barrel and the piston rod that can move along the cylinder barrel axis, be provided with on cylinder barrel and promote inlet and promote liquid return hole, promote inlet and all be connected with hydraulic system with the lifting liquid return hole, the drag conveyor connector is connected with piston rod.
Further: the drag conveyor connector is high strength mining round link chain.
Further: comprise the lift cylinder connector, lift cylinder is connected with back timber by the lift cylinder connector, and the lift cylinder connector is high strength mining round link chain.
The beneficial effects of the utility model are: the drag conveyor connector is connected with drag conveyor, inject emulsion (driving medium of the more use of hydraulic support is emulsion) by promoting inlet in lift cylinder, piston rod is retracted can promote drag conveyor.The height promoted as required, the filler of the high 100mm of relative cylinder charge hoisting depth (half round timber or spoil etc.) below drag conveyor, complete drag conveyor and promote.Safe operation process is reliable, and the staff does not need rib side cushioning filler, during dangerous the generation, can get back in hydraulic support rapidly.Easy to operate, the used time is shorter.Effect is remarkable, the scratch board conveyor hoisting depth is reached to 300～500mm at every turn.
The accompanying drawing explanation:
Fig. 1 is fully-mechanized mining working surface conveyer lifting appliance structure chart;
Fig. 2 is that fully-mechanized mining working surface conveyer lifting appliance uses state diagram;
Fig. 3 is the lift cylinder structure chart;
In figure, be labeled as: lift cylinder connector 1, shackle 2, cylinder barrel 3, pin rail 4, connecting ring 5, hydraulic tube 6, hydraulic support 7, drag conveyor 8, back timber 9, piston rod 10, drag conveyor connector 11, lift cylinder 12, filler 13, rodless cavity 14, piston 15, rod chamber 16, lifting liquid return hole 17, lifting inlet 18.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fully-mechanized mining working surface conveyer lifting appliance comprises hydraulic support 7, lift cylinder 12 and the drag conveyor connector 11 with back timber 9 and hydraulic system, lift cylinder 12 comprises cylinder barrel 3 and the piston rod 10 that can move along cylinder barrel 3 axis, on cylinder barrel 3, be provided with promote inlet 18 and promote liquid return hole 17, promote inlet 18 and promote that liquid return hole 17 all is connected with hydraulic system, drag conveyor connector 11, with piston rod 10, be connected.Hydraulic system is the part of hydraulic support 7, the valve that comprises a plurality of hydraulic cylinders (also referred to as column or jack) and control these hydraulic cylinder actions.The valve that existing hydraulic system has has unnecessary hydraulic fluid port, can utilize these hydraulic fluid ports to lift cylinder 12 emulsion floodings (driving medium of the more use of hydraulic support is emulsion).Do not have unnecessary hydraulic fluid port can tee junction and valve be installed on some hydraulic fluid port yet, by tee junction, separate emulsion injecting lift cylinder 12, by valve, control lift cylinder 12 actions.Lift cylinder 12 structures as shown in Figure 3, identical with the normal hydraulic oil cylinder structure, there is piston 15 cylinder barrel 3 inside, piston rod 10 is connected with piston 15, cylinder barrel 3 inside form respectively rodless cavity 14 and thick stick chamber 16 are arranged in piston 15 both sides, promote liquid return hole 17 and be communicated with rodless cavity 14, promote inlet 18 and be communicated with rod chamber 16, by promoting inlet 18 injection emulsions, to rod chamber 16, can make piston rod 10 retract.
Drag conveyor connector 11 is connected with drag conveyor 8, and by promoting inlet 18 to the interior injection emulsion of lift cylinder 12, piston rod 10 is retracted and can be promoted drag conveyor 8.The height promoted as required, the filler 13(half round timber of the high 100mm of relative cylinder charge hoisting depth or spoil etc. below drag conveyor 8), complete drag conveyor 8 and promote.Safe operation process is reliable, and the staff does not need rib side cushioning filler, during dangerous the generation, can get back in hydraulic support rapidly.Easy to operate, the used time is shorter.Effect is remarkable, the scratch board conveyor hoisting depth is reached to 300～500mm at every turn.
Drag conveyor connector 11 can be various hoisting appliances commonly used, such as wire rope, hanging belt etc., and the utility model is preferably high strength mining round link chain.High strength mining round link chain is widely used in winning equipment, draws materials easily, and intensity is high.High strength mining round link chain is linked to be annular by connecting ring 5, during lifting, high strength mining round link chain can be connected with the pin rail 4 of drag conveyor 8.
