Abstract
The utility model relates to Ferrous Metallurgy disintegrating apparatus field, especially a kind of disintegrating machine roller disassembly and assembly structure.Technical problem to be solved is to provide a kind of disintegrating machine roller disassembly and assembly structure effectively realizing the dismounting of disintegrating machine roller.Disintegrating machine roller disassembly and assembly structure, comprise slideway pedestal, the breaker roll bearing block be arranged on described slideway pedestal, broken roll shaft, hydraulic cylinder pedestal is provided with in described breaker roll bearing block, described hydraulic cylinder pedestal is fixedly installed at least one hydraulic jack, described hydraulic jack and broken roll shaft removably connect, and broken roll shaft pulls out from breaker roll bearing block by hydraulic jack.When reality uses, first hydraulic cylinder pedestal is arranged at the place that distance breaker roll bearing block is comparatively close, then by the hydraulic jack on hydraulic cylinder pedestal on broken roll shaft connects, only hydraulic jack need be driven broken roll shaft can be pulled out in breaker roll bearing block subsequently.The utility model is particularly useful for applying in the dismounting operation of heavy-duty crusher roller.
Description
Technical field
The utility model relates to Ferrous Metallurgy disintegrating apparatus field, especially a kind of disintegrating machine roller disassembly and assembly structure.
Background technology
Four-roller crusher is the disintegrating apparatus that iron and steel metallurgical industry generally uses, and is used for comminuting coke, anthracite.This equipment is pulverized material by the rotation of breaker roll.Because breaker roll volume is large, weight is at about 8000kg and four rollers are arranged in disintegrating machine casing, if carry out four rollers to change operation, four rollers must be drawn in and pull-out from casing, so dismounting and complex installation process, complexity, bring difficulty to breaker roll replacing work.At present the technics comparing that breaker roll is changed is fallen behind, rely on manpower to carry out dismantling and installing completely, not only there is the defect that labour intensity is large, operating efficiency is low of operating personnel, also there is the risk of the poor quality of replacing.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of disintegrating machine roller disassembly and assembly structure effectively realizing the dismounting of disintegrating machine roller.
The utility model solves the technical scheme that its technical problem adopts: disintegrating machine roller disassembly and assembly structure, comprise slideway pedestal, the breaker roll bearing block be arranged on described slideway pedestal, broken roll shaft is provided with in described breaker roll bearing block, also comprise hydraulic cylinder pedestal, described hydraulic cylinder pedestal is fixedly installed at least one hydraulic jack, described hydraulic jack and broken roll shaft removably connect, and broken roll shaft pulls out from breaker roll bearing block by described hydraulic jack.
Further, comprise two hydraulic jacks, described two hydraulic jacks removably connect with the two ends of broken roll shaft and respectively by parallel for broken roll shaft pull-out.
Further, described hydraulic cylinder pedestal is fixedly installed connecting plate, described hydraulic cylinder pedestal is fixedly connected on slideway pedestal by connecting plate.
Further, described connecting plate is fixedly connected on slideway pedestal by hold-down nut.
The beneficial effects of the utility model are: when reality uses, first hydraulic cylinder pedestal is arranged at the place that distance breaker roll bearing block is comparatively close, then by the hydraulic jack on hydraulic cylinder pedestal on broken roll shaft connects, only hydraulic jack need be driven broken roll shaft can be pulled out in breaker roll bearing block subsequently.Certainly, in order to more smooth-going realizes this pull-out process, general preferably two hydraulic jacks connect with the two ends of broken roll shaft respectively thus by parallel for broken roll shaft pull-out, can place the clamping stagnation during one end only pulling broken roll shaft like this.The utility model is particularly useful for applying in the dismounting operation of heavy-duty crusher roller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Be labeled as in figure: broken roll shaft 1, breaker roll bearing block 11, hydraulic jack 2, hydraulic cylinder pedestal 3, connecting plate 31, hold-down nut 32, slideway pedestal 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Disintegrating machine roller disassembly and assembly structure as shown in Figure 1, comprise slideway pedestal 4, the breaker roll bearing block 11 be arranged on described slideway pedestal 4, broken roll shaft 1 is provided with in described breaker roll bearing block 11, also comprise hydraulic cylinder pedestal 3, described hydraulic cylinder pedestal 3 is fixedly installed at least one hydraulic jack 2, described hydraulic jack 2 removably connects with broken roll shaft 1, and broken roll shaft 1 pulls out from breaker roll bearing block 11 by described hydraulic jack 2.
When broken roll shaft 1 pulls out by needs of production, only need first near slideway pedestal 4, to set up hydraulic cylinder pedestal 3, then the hydraulic jack 2 on hydraulic cylinder pedestal 3 is connected on broken roll shaft 1, ensuing, only need drive hydraulic jack 2, the unloading process of broken roll shaft 1 rapidly and efficiently can be realized.Certain, generally occur that broken roll shaft 1 clamping stagnation is in breaker roll bearing block 11 place to be placed in pull-out process, the preferably structure of two hydraulic jacks 2, to removably connect with the two ends of broken roll shaft 1 respectively by described two hydraulic jacks 2 and by the parallel pull-out of broken roll shaft 1, this prevents only have a hydraulic jack 2 to pull out broken roll shaft 1 that broken roll shaft 1 occurs and deflect and the clamping stagnation that causes.
In order to further be fixed by hydraulic cylinder pedestal 3, can be fixedly installed connecting plate 31 on described hydraulic cylinder pedestal 3, described hydraulic cylinder pedestal 3 is fixedly connected on slideway pedestal 4 by connecting plate 31.As shown in Figure 1, hydraulic cylinder pedestal 3 better can be fixed by slideway pedestal 4 by connecting plate 31, makes the pull-out process of broken roll shaft 1 more firm.General, in order to realize mounting and dismounting efficiently, preferably connecting plate 31 is fixedly connected on slideway pedestal 4 by hold-down nut 32.
Advantage of the present utility model is: one, achieve more smooth-going being drawn out of broken roll shaft 1; Two, the movement velocity of pull-out is controlled, thus realizes the controlled of broken roll shaft 1 movement velocity, to ensure the security of operation; Three, be in the position that crane easily lifts after the broken roll shaft 1 be drawn out, improve broken roll shaft 1 dismounting efficiency.
