Description
Technical field
A kind of down-hole crawler type all-hydraulic sling cart, belongs to Underground Mine haulage equipment technical field.
Background technology
Underground coal mine hanging device is one of main auxiliary equipment used in mining process.Along with the raising of production process automatic and mechanical level, arrange in the scope of operation, the installation, maintenance of equipment, dismounting, the transhipment of production site, uses hanging device more and more.To the compatible with environment of hanging device, operational suitability, functional diversity also proposes increasing requirement.
Current domestic conventional several hanging devices comprise special lifting lock, special lifting anchor pole, cantilevered Underwell used multi-function hoist, monorail hoist and other hanging device.The shortcoming of special lifting lock to carry out the lifting of lighter equipment, and can not carry out transverse shifting.Special lifting anchor pole shortcoming is the fixing cumbersome of lifting steel I-beam, and the reliability of lifting anchor pole is not high, and hoisting weight is limited, and the explosion-proof reliability of explosion-proof electric block is not high.The shortcoming of cantilevered Underwell used multi-function hoist must be fixed on underground orbit, and lifting weight is little, and space constraint factor is larger.Because monorail hoist to be hung in orbit and track is fixed on the hanging device on top board lifting and mobile device, its shortcoming requires height to back and supporting, needs the hanging bearing of failure-free suspended single-track.In addition, the weight that monorail hoist is sling can only move along the trend of track, weight sling and fall can not depart from below track too far away.Which limits its field of application.
As can be seen from the above, there is following shortcoming in above-mentioned hanging device: one, and hanging device function singleness can not meet the requirement of the variety of underground work environment and the polytropy of work requirements; Its two, hanging device all with top board for fixing bearing point, complicated and changeable due to roof Stress, also exists great potential safety hazard; Its three, lifting workman labour intensity large; Its four, these hanging devices, because fixing position, can not to extend with tunnel and mobile.As can be seen from the method and apparatus that above lifting is transported, the lifting appliance being specifically designed to underground coal mine main equipment is very limited, above-mentioned hanging apparatus only has single hoisting function, not only waste time and energy during operation, efficiency is low, and potential safety hazard is large, more serious by constraints such as spaces in addition.Be unfavorable for the production efficiency and the up-to-dateness that improve coal mining enterprise.
