Description
Technical field
The application relates to the tooth bar traction system, and a kind of like this device, by it tooth bar is fixed and held on the scraping transporter (armor face conveyors), especially, yet not specially not necessarily, is used for underground longwall mining.
Background technology
The longwell transport plane usually and power coal mining machine (being installed in the shearer (shearer) on the scraping transporter) operate together.Shearer carries out self traction by traction system along scraping transporter on both direction.The tooth bar traction system comprises that pin is connected to a series of tooth bars of support, and support is the so-called hill holder that is welded on each scraping transporter element (intermediate channel (line pan)).Shearer is by guide slip shoe (shoe) and tooth bar engagement, and guide slip shoe is only allowed free motion on the direction that shearer is advanced.Guide slip shoe has also held the tooth ingear drive sprocket with tooth bar, with the required tractive force of the material that provides cutting to be exploited.The driven wheel of shearer and the engagement of evenly spaced horizontal teeth, described horizontal teeth is extended between two isolated cheeks, thereby forms tooth bar.
All rack system must be born the shearer tractive force of all directions, and their maintenance method must be able to be tackled the guide slip shoe of shearer along with it presses against the trend of its fwd material along the transport plane process.
In traditional broadwall, shown in the Fig. 1-2 that obtains from the people's such as Lanfermann of the U.S. patent 4,155,600, drum-type cutting ore deposit machine 1 is by being fixed on drive wheel 3 on the longwell shearer 4 across scraping transporter 2.Drive wheel 3 and rotatably be supported on drive sprocket 5 or gear mesh on the machine frame 6, described machine frame 6 forms the part of drum-types cutting ore deposit machines.The tooth of drive sprocket 5 and tooth bar or install the engagement of 7 rack tooth.
As shown in Figure 2, scraping transporter 2 is made up of a plurality of delivery board parts or the intermediate channel 9 that connect together by Connection Element 8 head and the tail.By these Connection Elements, delivery board partly is maintained in relative to each other movable, so that the delivery board part can be adapted to the characteristic of ore bed.Each delivery board part links together by Connection Element 8, with the restrained motion relative to each other on the horizontal direction that transport plane 2 not only is provided, and on being arranged on ore bed the time, also provide the vertical or horizontal divertical motion (angling) of a delivery board part with respect to another.Rack gear arrangement 7 is installed on the scraping transporter 2, and it partly has identical horizontal motion with delivery board.When scraping transporter was shifted, rack gear arrangement also produced same vertical angular movement, and when needing the relief part of processing ore bed, the delivery board part also produces described motion especially.Rack gear arrangement 7 comprises the tooth bar of a plurality of elongations, and the tooth bar of described elongation is by removable tooth bar 7a and can not forming by mobile rack 7b.Support all tooth bars with scraping transporter 2 bonded assembly strut members or hill holder 10 directly or indirectly.Tie bolt 11 is used for each tooth bar is attached to hill holder 10.
Respectively, the removable tooth bar 7a of rack gear arrangement 7 and can not mobile rack 7b be provided with nose shape extension 12 at the place, two ends of each section, it protrudes downwards.This extension comprises the hole that is used to admit tie bolt 11, and tie bolt forms pivot.As shown in Figure 1, removable tooth bar 7a strides across joint A between the delivery board part.Removable tooth bar 7a is installed on two identical strut members 10, and described strut member 10 is used for installing an adjacent end that can not mobile rack 7b.These can not mobile rack each all entirely be arranged to partly extend along single delivery board.Therefore, two tooth bar hill holders 10 are fixed on delivery board interval location place partly.Each can not be located by tie bolt or sell 11 in its relative end to be fixed on two rack support parts by mobile rack 7b, and described rack support part additionally supports the adjacent end portion of removable tooth bar.
Each hill holder 10 is provided with the groove 13 that is positioned on half strut member, and described half strut member is near the joint between the delivery board part.Groove 13 in the hill holder 10 extends along the direction corresponding to the longitudinal direction of scraping transporter.Connecting pin 11 extends through above-mentioned groove, provides enough motions with respect to scraping transporter for the removable tooth bar 7a that is associated.Can not mobile rack 7b by tie bolt 11 and fixing with respect to scraping transporter 2, described tie bolt 11 is by extending through these tooth bars of the hole 13 that forms in remaining half strut member 10 ' keep.Each hole 13 ' and the diameter of pin 11 is consistent.
Therefore, commonly each intermediate channel 9 has two tooth bars 7.A tooth bar 7b is fixed on the central authorities of intermediate channel 9, and second tooth bar 7a is across the joint between the adjacent intermediate channel 9.Hinged relatively in recovery process between the intermediate channel can cause that the space between the intermediate channel changes very bigly, if the tooth bar between the intermediate channel is pinned to any adjacent plate securely, then when the drive sprocket 5 of shearer when fixing tooth bar 7b moves on to tooth bar 7a between the intermediate channel, this can cause problem.Common terms of settlement is that the rack pins 11 between the intermediate channel is maintained in the groove 13 of hill holder 10, rather than remains in the hole.Like this, the error on the tooth pitch between the adjacent rack is halved and is relatively good to the drive sprocket 5 of shearer, but has increased the fixing difficulty of pin, and this is because pin 11 must be allowed to move along groove 13.
Particularly, shown in Fig. 3,4,5, longwell intermediate channel 9 comprises the structure plate or the guar plate 14 of goaf side.Location, guar plate 14 contiguous tooth bar traction system place.For tooth bar 7 is fixed on the hill holder 10, pin 11 inserts hill holder 10 by the opening on the guar plate 14 15.
Pin has head 19, and its opening than the sidewall that passes through hill holder 10 is big, can not pass hill holder 10 so sell 11.For pin 11 is remained in the hill holder 10, holding plate 20 drops in the head and the zone between the guar plate 14 of pin 11.Holding plate 20 stops pin 11 to be deviate from from hill holder 10.
Therefore, shown in Fig. 3-5, traditional tooth bar 7 remains in the hill holder 10 by the pin 11 of band head, and described pin 11 can only be assembled by the opening 15 in the guar plate 14 of goaf side.The pin 11 of band head self keeps by holding plate 20, and described holding plate 20 is positioned at the salient 21 of the guar plate 14 that is welded to goaf side.20 of holding plates keep putting in place by action of gravity, but can do more firmly by other fastener, for example by bolt or spring pin.
Hill holder 10 significant feature are for half flexible rack system provides attachment point on intermediate channel 7, and along described rack system, shearer self traction is to downcut material from ore bed.The character of this system is: if tooth bar 7 damages, can easily be replaced, but hill holder 10 can not be repaired under dangerous environment, because needed cutting and welding are unallowed.Therefore, need crash-resistant, failure-free, simple tooth bar-hill holder to keep assembly.
