Description

A kind of lift up rapidly loading-unloading vehicle device of underground mine use hydraulic support creeper

Technical field

The utility model relates to a kind of coal mine hydraulic supporting and withdraws machinery, relates in particular to a kind of lift up rapidly loading-unloading vehicle device of underground mine use hydraulic support creeper.

Background technology

At present, coal mine underground hydraulic support frame withdraws entrucking and adopts 2 kinds of entrucking modes, and a kind of mode is with the direct scraper entrucking of trackless rubber tire support forklift; Another kind of mode is with being transported by rail system after flat car entrucking.Front a kind of mode is in the modern large-scale mine application of minority, and rear a kind of mode is that most mines adopt.

Adopt flat car entrucking mode to there are again 2 kinds of general modes: a kind of mode is at working face open-off cut intraocular or withdraws in lane with the entrucking of prop drawer cooperation creeper; The second way is to withdraw the built-in staking lifting of gallery chamber, establishes lifting beam installation Chain block and plays sling cart.All there is more problem in these two kinds of modes.

(1) with prop drawer, be fixed creeper entrucking:

Fixedly creeper is a kind of old-fashioned slide type loading device, adopts multistage slide plate combination, is elevated to successively flat car height formation entrucking domatic, uses prop drawer towing bracket along domatic slippage upper flat plate car; The problem existing is: 1. flat car earth anchorage, otherwise vehicle moves after easy; 2. creeper is fixing docking, and guider is non-adjustable, and forward position, base is easily gnawed props up support; 3. after support is got on the bus, set bolt difficulty is installed, is difficult to centering, with monomer coordinate front, rear, left and right back and forth ceiling hold look for eye, the effort of taking a lot of work is dangerous.

(2) with Chain block, play sling cart:

The problem existing is: 1. will set up special chamber, upper girder steel, installs Chain block, and engineering quantity is large, can not be multiplexing after special chamber once builds up; 2. 4 of tackleses can not synchronously and need firm, the bad grasp of balance, poor stability, workman can not operated from a distance; 3. speed is slow, and group loading time is long, and efficiency is low.

Utility model content

The purpose of this utility model is the lift up rapidly loading-unloading vehicle device that a kind of underground mine use hydraulic support creeper will be provided, while solving old-fashioned creeper entrucking, take a lot of work, time-consuming, and Chain block rises, and sling cart speed per hour degree is slow, group loading time is long, inefficient problem.

The purpose of this utility model is achieved in that this device comprises: frame construction, column, guide pad, play cat chain and eave tile, adjust frame jack, track, car puller, car arrester, creeper, hinging pin shaft, climb car guide pad, hinged jack, flat car, go-cart eave tile, chain, jockey sprocket, bi-directional drive motor, column safety valve, column hand-operated direction valve, adjust frame jack hand-operated direction valve, hinged jack hand-operated direction valve, bi-directional drive motor hand-operated direction valve and hydralic hose, column is arranged on four angles of frame construction, the head of each column is all connected with guide pad, cat chain and eave tile on guide pad, have been connected with, the top of frame construction is equipped with and is adjusted frame jack, in frame construction, stop to have flat car, there is go-cart eave tile the middle part of flat car, and go-cart eave tile is connected on chain, and chain plate is on jockey sprocket and bi-directional drive motor, the baseplane of frame construction is provided with track, car arrester is housed in orbit, is furnished with a car puller rail is intracardiac, creeper is equipped with in one end in frame construction, frame construction is connected with creeper by hinging pin shaft, creeper is assembled by the domatic box-shaped structural members such as three, and creeper end face both sides are welded with climbs car guide pad, and hinged jack is equipped with in side, install each function action by HYDRAULIC CONTROL SYSTEM,

Described hydraulic system comprises: column safety valve, column hand-operated direction valve, tune frame jack hand-operated direction valve, hinged jack hand-operated direction valve, bi-directional drive motor hand-operated direction valve and hydralic hose, hydralic hose has liquid feeding end and outlet end, column hand-operated direction valve, adjust the liquid feeding end of frame jack hand-operated direction valve, hinged jack hand-operated direction valve and bi-directional drive motor hand-operated direction valve all to have with hydralic hose with outlet end that liquid feeding end is corresponding with outlet end to be connected, column hand-operated direction valve is connected with column by column safety valve; Adjust frame jack hand-operated direction valve to be connected with adjusting frame jack; Hinged jack hand-operated direction valve is connected with hinged jack; Bi-directional drive motor hand-operated direction valve is connected with bi-directional drive motor.

Beneficial effect, owing to having adopted such scheme, adopts 11# I steel composite to be welded into a frame construction, and lifting frame height is at 3.0 meters, and 2.5 meters of width, can be installed on working face open-off cut eye or withdraw in gallery and rail system docking, need not lift by crane specially chamber.Framework is made intensive treatment according to the weight of support, can bear the heaviest support lifting in ore deposit side intensity.Use 4 of existing ZF6500 type hydraulic support columns on ore deposit to arrange as falling unit lifting in 4 jiaos of frame construction, column is hydraulic support column, at its head, there is guide pad, fixed hoisting anchor chain and eave tile on piece, a tune frame jack is established for adjusting pole level in the top of frame construction.The bottom of frame construction is provided with track, and consistent with transportation lane rail type, vehicle can freely pass through, and track is provided with rotary type car arrester, opens at ordinary times, does not affect vehicle pass-through, has erected the effect of holding up traffic during entrucking.Car puller is that hydraulic pusher can rotating, promotes flat car turnover frame construction, does not want artificial go-cart, realizes operating remote, and support is adjustable in any position height of column stroke, can locate.One end hinge joint creeper of frame construction, with hinge joint bearing pin, fix, creeper is assembled by the domatic box-shaped structural members such as three, end face both sides are welded with climbs car guide pad, side is installed hinged jack and is regulated height, and the gradient of capable of regulating creeper, along leading support entrucking, hydraulic power is derived from work plane emulsion power pack, and support is drawn by prop drawer.While having solved old-fashioned fixedly creeper entrucking, take a lot of work, time-consuming, and Chain block rises, and sling cart speed per hour degree is slow, group loading time is long, inefficient problem, has reached the purpose of this utility model.

Advantage: this covering device can be realized lift up rapidly support, entrucking is not manually backtracked eye and is tightened up a screw; During entrucking, use prop drawer towing bracket, can import smoothly frame construction, after lifting fast, with car puller, push smoothly flat car, realize rapid wagon loading, safety, efficient, reliable, the scope of application is wide, can be used for support and climbs car, entrucking, bracket assembled, disintegration, imperial car, also can be used for entrucking and the assembling of other large-sized object, efficient and convenient.On-the-spot use alleviates workman's physical labor intensity, improves the safety of work efficiency and support entrucking, assembling.
