Description
Technical field
The present invention relates to a kind of mine laneway driving loading machine, particularly a kind of half coal rock tunnel big gun pick bastard coal racking machine that half coal rock tunnel headwork is carried out explosion respectively, bastard coal is loaded and transported respectively in the face of coal petrography in the colliery.
Background technology
At present, in the driving of colliery alternate heading, driving technology commonly used has two kinds: a kind of is to adopt to combine tunneling process, tunnels with medium-coal-rock roadheader; Another kind is to adopt the big gun tunneling process, adopts the disposable explosion coal petrography of full section, and the coal, the cash that with muck equipment explosion are fallen then load transportation; Muck equipment commonly used has scraper mucking, bucket dirt loader etc.These two kinds of technologies all can not realize branch pick, the packing transportation of coal and spoil at present, and the bastard coal that loads in mixture together will separate through a series of washing process, has increased excavation cost.At present directional blasting technology can be realized the difference explosion of coal petrography, the coal on promptly first explosion upper strata, and the rock of explosion lower floor again after shipment is clean, or the upper strata is coal for rock lower floor, realizes dividing pick.But present carrier loader can't solve the shipment respectively of bastard coal after the half coal rock tunnel explosion or claim dividing load and carry.Realize the bastard coal dividing load and carry, can only hovel coal from one place to another by manual work during the big gun pick.It is big to do labour intensity like this, and efficient is low, poor stability.
Summary of the invention
Can not realize the deficiency of half coal rock tunnel driving face bastard coal dividing load and carry in order to overcome existing charging appliance; The present invention provides a kind of half coal rock tunnel big gun pick bastard coal racking machine; Can be after half coal rock tunnel driving face be implemented the explosion of coal petrography difference; Make the bastard coal dividing load and carry, realize the mechanization that bastard coal loads and transports respectively, improve work efficiency and driving coal recovery; And the last sheaf space that can go deep into after the half coal rock tunnel driving face explosion loads and transports.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
Half coal rock tunnel big gun pick bastard coal racking machine mainly is made up of spy propulsive mechanism and hydraulic system before body, running part, transporter, shovel board, spillplate assembly, shovel plate shipment portion elevating mechanism, the shovel plate shipment portion.Wherein: combine as a whole before and after shovel board and the transporter, close and claim shovel plate shipment portion, be positioned at the top of this machine.The critical piece supporting frame of body is the carrier of other part of this machine.Running part is a crawler travel portion, is connected in the bottom of supporting frame both sides; Shovel plate shipment portion elevating mechanism is connected between shovel plate shipment portion and the supporting frame; The spillplate assembly is connected in the rear end of shovel board, the front portion of transporter.Elevating mechanism and rear lifting mechanism before shovel plate shipment portion elevating mechanism comprises.The bottom of forward and backward elevating mechanism be installed in supporting frame above, the bottom-hinged of the guide rail platform of upper end of the two and guide assembly.Being inlaid in the guide rail balladeur train that slides on the guide rail of guide rail platform and the bottom of transporter connects firmly.Between guide rail platform and transporter or guide rail balladeur train, be connected with the propelling oil cylinder.Guide assembly, propelling oil cylinder are visited propulsive mechanism before constituting shovel plate shipment portion.The shovel board is by loader mechanism on the plate of shovel plate, shovel, constitute with the loading driving mechanism of loader mechanism transmission etc.Hydraulic system is the airborne hydraulic system.
The invention has the beneficial effects as follows:
1. dig half coal rock tunnel for big gun a kind of loading machine that can make the bastard coal dividing load and carry is provided; Realize the mechanization of bastard coal dividing load and carry, increase work efficiency and safety, reduce labour intensity; Solve half coal rock tunnel driving coal resources effectively and reclaim problem, make the driving coal recovery more than 90%.
2. on the bastard coal racking machine spillplate is housed, can big gun be dug the interception of coal and spoil on the shovel plate when blowing out, prevent that the bastard coal explosion is scattered, avoid the frequent mobile of secondary shipment and bastard coal racking machine, improved efficiency of loading.Simultaneously, prevent that coal or spoil from collapsing, protect the bastard coal racking machine to be without prejudice effectively.
3. crawler travel portion moves flexibly, goes up and down before and after shovel plate shipment portion has, preceding spy propulsion functions, visits the last sheaf space that is deep into after the explosion before can be flexibly and easily and loads and transports, and the upper strata can also can be the rock stratum for the coal seam.Probe into the degree of depth and can reach 4.5 meters, the excavation operation that satisfies a circulation requires: 4.5 meters of three times, 1.5 meters/each drilling depth of big gun pick, driving step pitches.Realize the dividing load and carry of half coal rock tunnel coal and spoil.
