Description
Technical field
The present invention relates to a kind of coal mining facility, particularly a kind of continuously lateral coal cutting for level or the propulsion of nearly level
The Height Adjustable carrier bar felling and transporting coal all-in-one of fortune coal.
Background technology
It is to solve existing girdle or relatively thin middle thickness level or nearly water that cut continuous coal cutting in side fells and transports coal all-in-one
The critical facility of level coal mechanization manless working face, it drives drive chain horizontal cyclic to move by drive sprocket, using in drive
The mode that the carrier bar that dynamic chain connects arranges coal cutting teeth is realized mining, and forms fortune coal crossheading using carrier bar and fuselage, thus being formed
Fell and transport the all-in-one machine structure of coal one, fuselage is used as load bearing component and the guiding parts of carrier bar, fuselage is by multiple case units even
Connect and form, between each case unit, pass through dumbbell pin connected mode, fuselage height and coal mining amplitude correlation, coal mining width
Degree sets generally according to coal seam thickness.But existing preservation coal seam thickness generally has certain amplitude of variation on bearing,
Therefore, for the existing all-in-one determining height, can only back production set thickness coal seam, when squeeze, the coal of back production
In product, spoil composition increases, and affects Coal Quality, when coal seam thickens, coal recovery rate is low.For this reason, it may be necessary to felling and transporting coal one
Body machine carries out the improvement that adjusts with Coal Seam Thickness Change of height of mining, in requisition for a kind of be adapted therewith fell and transport coal height
I.e. Link plate height is adjustable fells and transports coal carrier bar.
Content of the invention
It is an object of the present invention to provide a kind of Height Adjustable carrier bar, for the continuously lateral coal cutting of level or the propulsion of nearly level
The fortune coal or fortune coal and the coal cutting that fell and transport coal all-in-one of fortune coal, it fells and transports coal height and adjusts with the distance between coal-winning machine upper/lower guide
Whole and automatically change, fell and transport coal all-in-one for accordingly adjust coal mining height with Coal Seam Thickness Change.
For achieving the above object, the present invention adopts the following technical scheme that.
A kind of Height Adjustable carrier bar, is driven and run setting to be guided by guide rail in space, for water by haulage chain
The continuously lateral coal cutting of flat or near level propulsion transports the fortune coal or fortune coal and the coal cutting that fell and transport coal all-in-one of coal；Carrier bar is by carrier bar originally
Body and extrusome are upwardly formed only retractable telescopic combinative structure in Link plate height side, and carrier bar passes through carrier bar body and fells and transports
The haulage chain of coal all-in-one connects, carrier bar working depth by the upper rail that Link plate height direction upper and lower ends are located on fuselage and under
The distance between guide rail limits, and carrier bar makes it highly change with the distance between upper rail and lower guideway by automatic telescopic structure
And accordingly elongate or shorten.
Using the present invention of preceding solution, carrier bar forms extension type combinative structure, and its working condition height is with upper
The distance between guide rail and lower guideway change and accordingly automatically elongate or shorten.For, in coal-winning machine, part carrier bar being arranged
Coal cutting teeth, this part carrier bar has coal cutting and the function of fortune coal, by being respectively provided with the side of coal cutting teeth in carrier bar body and extrusome
Formula, can achieve that height of mining changes and respective change with Link plate height, and the carrier bar being only used for transporting coal is not required to arrange coal cutting teeth, its
Fortune coal amplitude also respective change.When coal seam thickness is thickening or thinning, realized by way of adjusting coal-winning machine fuselage height
The corresponding adjustment of distance between guide rail and lower guideway so that Link plate height formed adaptive accordingly elongate or shorten, from
And realize the purpose of coal mining height adjustment.
Preferably, described only retractable telescopic combinative structure is formed by rectangle grafting fit structure.This rectangle grafting
Cooperation is rectangle connection-peg and the pairing of rectangle spliced eye is formed, and sets connection-peg including in carrier bar body, sets spliced eye in extrusome
Scheme, and set spliced eye in carrier bar body, set the scheme of connection-peg in extrusome.Utilize between carrier bar body and extrusome
Rectangular configuration reliably limits the characteristic circumferentially rotating and forms only telescopic annexation, and it can be cut using carrier bar to greatest extent
Face shape improves bonding strength therebetween.
It is further preferred that described automatic telescopic structure is formed by the effect of Self-resetting flexible member.Carrier bar is in Self-resetting bullet
Under the resilient force of spring, carrier bar both ends are connected on the guide rail at two ends all the time, and during guide rail Distance Shortened, spring is compressed chain
Plate shortens, and when guide rail distance increases, carrier bar extends under the resilient force of spring automatically.Wherein, Self-resetting flexible member can
