Description
Technical field:
The utility model relates to the slicer-loader of a kind of big gun pick, blast mining face use.Particularly relate to the all-hydraulic slicer-loader of a kind of side dump.Belong to coal mine development machine tool technical field.
Background technology:
Coal road adopts when blowing out the formula driving under the coal mine, need be loaded into the coal that slicer-loader falls colliery driving, blast mining face explosion and move to ground on the mine car.At present, the slicer-loader that big gun pick, blast mining face use is the convertible all-hydraulic slicer-loader in front and back, and it mainly is made up of frame, walking mechanism, support, scraper bowl, scraper bowl seat, dipper-arm, dipper-arm oil cylinder and hydraulic operating system etc.Walking mechanism is installed on the frame both sides, and support, hydraulic operating system are fixed on the frame.Scraper bowl is fixed on the scraper bowl seat, and dipper-arm one end is hinged on the support, and the other end and scraper bowl seat are hinged, and the dipper-arm oil cylinder is hinged on the support, and its piston end and scraper bowl seat are hinged.During slicer-loader work, the coal that explosion is fallen by hydraulic operating system control scraper bowl shovels to mine car, and the drive walking mechanism seesaws.This slicer-loader mainly has the following disadvantages:
1, adopt the convertible structure in front and back, the required activity space that overturns before and after its scraper bowl is bigger, and underworkings is narrower, and therefore load the inapplicable down-hole of this slicer-loader, can only be applicable to aerial pickup.
2, adopt bearing pin hinged between walking mechanism and slicer-loader frame, as Fig. 1.Because bearing pin comes off easily, ruptures, so connection reliability is relatively poor between walking mechanism and frame.This in addition connecting mode makes that the slicer-loader volume is bigger, and the slicer-loader space shared in the down-hole is also bigger.
3, hydraulic operating system adopts variable pump and variable displacement motor to control, as Fig. 2, and the system architecture complexity, the valve member of control is more again, because pollution is bigger under the coal mine, stops up valve member easily, causes Control Failure to form the system failure.And the down-hole service clearance is narrow, difficult maintenance.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of volume is less, the all-hydraulic slicer-loader of connection reliability side dump higher, that hydraulic control system is simple, easy to maintenance between less, the walking mechanism of the required activity space of upset and frame.
The purpose of this utility model is achieved in that the all-hydraulic slicer-loader of a kind of side dump, comprise frame, walking mechanism, support, scraper bowl, the scraper bowl seat, dipper-arm, dipper-arm oil cylinder and hydraulic operating system, walking mechanism is installed on the frame both sides, support, the hydraulic operating system device is on frame, dipper-arm one end is hinged on the support, the other end and scraper bowl seat are hinged, the dipper-arm oil cylinder is hinged on the support, its piston end and scraper bowl seat are hinged, be characterized in being connected with the side dumping oil cylinder between scraper bowl and scraper bowl seat, the side dumping oil cylinder is hinged on the scraper bowl seat, and its piston end is hinged on the scraper bowl.The side dumping cylinder action overturns scraper bowl to the left or to the right the material in the scraper bowl is unloaded as on slicer-loader left side or right side mine car or the drag conveyor during work.Therefore the required activity space of slicer-loader is less, relatively is suitable for the loading in downhole coal mine tunnel.
Walking mechanism of the present utility model directly is weldingly fixed on the both sides of slicer-loader frame.Weld seam can not come off, and connection reliability is good, and volume is little, and slicer-loader takes up room little.
Hydraulic operating system of the present utility model comprises constant displacement pump, walking control valve, balancing brake valve, running motor and connecting line, valve member, constant displacement pump links to each other with the oil-feed of walking control valve, the oil-out of walking control valve links to each other with fuel tank, vertical actuator port of valve of walking operation and linking to each other into and out of hydraulic fluid port of balancing brake valve, the actuator port of balancing brake valve links to each other with motor.System architecture is simple, the valve group is less, and contamination resistance is strong, and Operation and Maintenance is simple, and cost is low, relatively is fit to the operating mode in colliery.
