Description
The present invention is broadly directed to the field of cracking machine that aggregation is broken into small pieces.More specifically, the present invention relates to gyratory crusher, it has fastening spring, and in the fragmentation procedure process, this spring is used for the spherical cover of a disintegrating machine submissively is held on broken hood tube.
Disintegrating machine is used for big aggregation particle (for example rock) is broken into little particle.Fig. 1 and 2 shows a kind of concrete disintegrating machine type, and promptly gyratory crusher 12.Shown in disintegrating machine 12 in, big particle is fed in the feeding distributor 14 (Fig. 2), particle is assigned in the feeding funnel 16 herein.Specifically with reference to Fig. 2, big particle falls in the spherical annular space 18 that overlaps between the 20 and one cover tube 22.Spherical cover 20 is fixed on the spherical shell 24, and spherical shell 24 then is screwed in by screw thread and adjusts on the ring 26.This screw is twisted the height that connects permission spherical shell 24 and can be regulated with respect to adjusting ring 26, thereby can be adapted to particle size in a big way.Hydraulic pressure lock post 28 can be used for will adjusting selectively ring 26 and is locked on the spherical shell 24.
Adjust ring 26 and be clamped on the mainframe 30, but can vertically move, will describe in more detail below with respect to mainframe.Alignment pin 31 makes adjustment ring 26 keep aiming at mainframe 30.Cover tube 22 is fixed on the crushing head 32, and crushing head 32 then is fixed on the main shaft 34.Main shaft 34 prejudicially and be rotatably installed in the eccentric 36, and this eccentric 36 is installed in rotation in the mainframe 30.Eccentric 36 is driven by a pinion 40 and a gear 42 by a countershaft 38, and this pinion 40 is fixed on the countershaft 38, and gear 42 is fixed on the eccentric 36.
Because main shaft 34 off-centre are installed in (crushing head 32 that links to each other with main shaft simultaneously and cover tube 22 also are installed in the eccentric 36 prejudicially) in the eccentric 36, the annular space 18 between therefore spherical cover 20 and the cover tube 22 is uneven.That is, space 18 changes around the circumference of cover tube, so this space is included in a relatively large gap of cover tube one side and a relative less clearance at cover tube opposite side.When driving eccentric 36, main shaft 34 (and the crushing head 32 that links to each other and cover tube 22) is determined a circular passage (that is, because eccentric the installation), thereby is similarly turned round in the circular passage in large and small gap.Crushing head 32 and cover tube 22 allow the material of feeding to enter in the annular space 18 around this screw of crusher axis.Then, when material further enters annular space 18 times, make material be subjected to impacting between cover tube 22 and the spherical cover 20 and compress by a series of step.Because of annular space 18 diminishes gradually, thereby the material of input is broken into required size.
In the fragmentation procedure process, can't often run into particle and be difficult to broken situation, be called " field trash " situation (tramp) sometimes.Little field trash generally all can have no difficulty to pass through system.Yet, even little sometimes field trash also can block between cover tube 22 and spherical cover 20.At this moment, move by adjusting the vertical of ring 26, spherical cover 20 can lift slightly and make little field trash pass through disintegrating machine.This vertical the moving of adjusting ring 26 (and spherical shell 24 that links to each other and spherical cover 20) provided by a spiral spring device 44, and this spiral spring device 44 will be adjusted ring 26 and be clamped on the mainframe 30.
Shown in disintegrating machine 12 in, spiral spring device 44 comprises 16 helical spring parts 46 that are provided with separatedly along circumference around mainframe 30.Each helical spring parts 46 comprises that one is fixed in upper spider flange 48 on the mainframe 30, once spring section 50 and 5 helical springs 52 between upper spider flange 48 and lower spring part 50.3 spring bolts 54 pass lower spring part 50, upper spider flange 48 and adjust ring 26.Spring nut 56 is fixed in the lower end of each spring bolt 54.Shown in arrange that helical spring 52 leans the downside at upper spider flange 48, and presses against on the lower spring part 50, lower spring part 50 then then pulls down on spring bolt 54, nut 56 and the adjustment ring 26 that links to each other.
Above-mentioned layout is according to spherical shell 24 and cover tube 22 and be mingled with the situation of material interlock, overcomes the power of helical spring 52 and makes to adjust and move on the ring 26 (and the spherical shells 24 that are attached thereto and spherical cover 20), thereby can make little field trash can pass through system.Should be understood that the compression owing to helical spring 52, any vertical mobile all order of therefore adjusting ring 26 causes spherical cover 20 to act on the increase of particle upward pressure.The initial clamping force that spiral spring device 44 produces (promptly adjusting ring 26 with the clamping force before lifting on the mainframe 30) is approximately 1,000,000 (1,000,000) pound.
When big inclusion particle blocks in annular space 18,, thereby the motor (not shown) that drives countershaft 38 is stopped operating because the pressure that produces between inclusion particle, spherical cover 20 and the cover tube 22 is enough big.At this moment, must lift the position of adjusting ring 26 to one removing field trashes and eliminate this field trash, thereby increase annular space 18, the permission inclusion particle falls or is pushed out annular space 18.
Be raised up to the removing position in order to adjust ring 26, shown disintegrating machine 12 comprises 4 hydraulic actuators 58 (Fig. 1), and ring 26 is adjusted in their extended upwards pushings.Hydraulic actuator 58 must can provide enough power, and this power not only can be lifted the weight of adjusting ring 26, spherical shell 24 and spherical cover 20, but also can overcome the clamping force of spiral spring device 44, and this clamping force increases with the compression of spring 52.Lift the required power of adjustment ring and be approximately 1,500,000 (1500000) pounds or bigger.So big power needs very high hydraulic pressure, and this can cause pipeline to be broken through or leak.
In addition, lifting the adjustment ring at 26 o'clock, helical spring 52 compressible amounts are subjected to certain limitation.This restriction is not only because the spring force of this device can surpass the maximum, force that actuator 58 applies, and is because the decrement (being the length after helical spring compresses fully) of helical spring 52 is restricted.For example, above-mentioned disintegrating machine 12 is designed to make adjustment ring 26 to lift only about 2 inches.
