The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model shown in Figure 1 is combined the structure of pick with extensible belt conveyor.
This conveyer is made up of headstock 1, storage band portion, changeover portion 9, fuselage, tail 10, drive unit 12 etc.These machine rear portion three parts: the structure of changeover portion 9, fuselage, tail 10 is with organic type is identical.
Headstock 1 adopts the inverted T shape structure: the framework of fixed drive device 12 is inverted T shape, and two head rolls of drive unit 12 and motor thereof, reducer are separately fixed at the vertical member both sides of inverted T shape framework; The case structure that has replaced traditional extensible belt conveyor.Compare with traditional case structure headstock, have simple in structure, easy for installation, easy care, help shortening the characteristics of head length.
Storage band portion or title storage cassette holder are made up of storage band bogie 2, traction car 3, track frame 4, door frame 5, tensioning car 6, entrainment device 7, tensioning apparatus 8, protecting wire net 11 etc.The framework of storage band portion is assembled with Bolt Connection by track frame 4, door frame 5 and middle frame; Be package assembly, be convenient to quick assembling, rather than traditional stationary frame structure.Track frame 4 is connected and fixed with the lower end of door frame 5; The upper end of middle frame and door frame 5 is connected and fixed, and carrier roller frame is installed on it.The characteristics of this machine are: storage band minister degree is little, only be 18 meters, thereby shortened the shortest use length of complete machine, only is 20 meters; Storage band portion adopts tower structure, and storage belt number is many, can store up and be with 8 layers; The structure of storage band portion is convenient to quick assembling.
The structure of the drive unit of headstock of the present utility model shown in Figure 2.Two head rolls of drive unit 12 are arranged in the both sides of inverted T shape structure stay, are driven by reducer by two motors respectively.Two motors adopt variable-frequency motor.
The structure of tensioning apparatus of the present utility model shown in Figure 3.Tensioning apparatus 8 adopts air motor winches 15 to add spring buffer 14 compound modes: the tensioning wire rope is walked around two rope sheaves of rope sheave seat 21 on the tensioning car 6 and the fixedly rope sheave of tensioning apparatus by air motor winch 15, is connected to spring buffer 14 through tension indicator 13.When this compound mode can reduce tensioning to the impact of adhesive tape and structural member.
The form that adhesive tape rope of the present utility model shown in Figure 4 and adhesive tape twine.Storage band bogie 2 has been installed large and small seven changed course cylinders, large and small eight changed course cylinders respectively have been installed on the tensioning car 6, adhesive tape and adhesive tape rope are wrapped in the two 15 eight layers of storage of the formation band structures on the changed course cylinder, and see from the side the storage band structure up-narrow and down-wide, successively widen, be turriform, so claim tower structure.Adopt tower structure to help dwindling the height of storage band perpendicular separation, increase storage belt number.The storage of eight layers of storage band structure is with 100 meters only to need 18 meters long, has shortened the length of storage band portion greatly, thereby has shortened the shortest use length of complete machine.
Structure at the portion of storage band of the present utility model shown in Fig. 5～7 storage band bogie.Wherein Fig. 7 removes the C of storage band bogie of crossbeam to view.Storage band bogie 2 is by formations such as changed course cylinder I (16), changed course cylinder II (17), base 18, side plate 19, bogie cover plates 20.Base 18, side plate 19, bogie cover plate 20 and crossbeam etc. constitute the framework of this one.On storage band bogie 2, (17) three of the less changed course cylinder II of (16) four of the bigger changed course cylinder I of diameter, diameter are installed laterally.Seven the changed course cylinder along bogie cover plate 20 bottom surfaces to heading be tilted to down the layout and size alternately.The front end of storage band bogie 2 and headstock 1 are fixed by Bolt Connection.The rear end of storage band bogie 2 connects with changeover portion 9 by the framework of storage band portion, and fixes by Bolt Connection.
Structure at the portion of storage band of the present utility model shown in Fig. 8～10 tensioning car.Tensioning car 6 is by formations such as vehicle frame 22, tensioning car bonnet plate 23, changed course cylinder I (16), changed course cylinder II (17), road wheel 24, rope sheave seats 21.On the vehicle frame 22 of tensioning car 6, each four of the less changed course cylinder II (17) of diameter bigger changed course cylinder I (16), diameter laterally are installed, be tilted to down layout and size alternately along tensioning car bonnet plate 23 bottom surfaces.The incline direction that the cylinder that respectively alters course on the tensioning car 6 is arranged is with the incline direction that the changed course cylinder is arranged on the bogie 2 opposite with storage, forms up-narrow and down-wide tower structure after the cylinder that respectively alters course of the two (6,2) twines adhesive tape.Road wheel 24 is arranged at tensioning car 6 bottoms, is used for along the 4 rolling walkings of track frame.There are rope sheave seat 21 and rope sheave in tensioning car 6 rear portions, are used to twine, strain the tensioning wire rope of tensioning apparatus 8.
Structure at the portion of storage band of the present utility model shown in Figure 11～13 track frame.Track frame 4 is made of bogie side frame 26, crossbeam 27 etc.Fix by Bolt Connection between the track frame 4.The front end of bogie side frame 26 has plug-type location-plate 25, locatees assembling when being used for connecting between the track frame 4 fast and uses.
The motor of the utility model drive unit 12 adopts variable-frequency motor, perhaps adopts common alternating current generator, adds frequency converter timing in its control loop.The starting curve of frequency control is " S " type curve and two kinds of linearities, and this curve can be adjusted according to actual condition, thereby reduces the dynamic tension of starting to equipment.Its Starting mode has that starting power is little, priming speed steadily, electrical network is impacted advantages such as little.
The utility model main feature is: store up band portion weak point, the shortest use length weak point of complete machine, can assemble fast, so claim " the quick combined extensible belt conveyor of short distance " again.Storage band portion storage belt number is many, can store up and be with eight layers; It is 18 meters only that 100 meters its length are with in storage, makes only 20 meters of the shortest use length of complete machine; Add bridge conveyor, only need the distance of 30 meters of general picks, just can adopt the pick mode of combining, " shop " afterwards while digging, the longest transportation range can reach 2500 meters.Be particularly suitable for when adopt combining tunneling process driving stope drift active workings, using, for " shorten general pick distance, adopt as early as possible and combine pick " purpose used.It also can use in the stope haulage gate, is especially requiring under the short situation of extensible belt conveyor length.
