Description
Technical field
The present invention relates to crusher technical fields, and in particular to Single-Cylinder Hydraulic Cone Crusher rack attaching/detaching apparatus.
Background technique
Single-Cylinder Hydraulic Cone Crusher can be widely applied to the industry neck such as each black, coloured, non-metal mine and sand material
Domain.The features such as crushing force is big, high production efficiency, lamination crushing, finished product grain shape are uniform, attrition component consumes less, operating cost is low makes
Obtain Single-Cylinder Hydraulic Cone Crusher one indispensable key player of performer in broken industry.Its principle is to pass through a pair
Meshed gears drives eccentric stiffener to do a swing campaign, to the material attrition crushing in crusher chamber.
Just because of such working principle, there are a strict requirements to the cooperation of its upper and lower straightening machine frame, therefore common single cylinder
It also needs to increase interference while the upper and lower straightening machine frame of hydro cone-crusher is assembled together frequently with the fit system of screw thread and match
Close, due to the relationship of rack construction itself and installation space, the personnel consumed during mounting and dismounting upper spider and when
Between cost it is relatively high, common disassembly mode have following 4 kinds: 1. it is manually that the jackscrew of surrounding is uniform, circulation is tightened, will be upper
Rack opens.2. increase wedge mouth at upper spider and lower bearing bracket cooperation, by wedge mouth around beat the method for voussoir will be upper
Rack ejection.3. being worked simultaneously by both the above one.4. steel plate is welded on upper spider, then it is placed on using jack
In frames, upper spider is opened, disassembly is completed to need to cut open welding steel using gas flame cuttiug, is easy to hurt machine
Frame.Above several various ways are manual operation, need surrounding simultaneously, uniform to exert a force, and expend personnel cost and time cost,
And be not available in upper spider disassembly, influence produced on-site efficiency.
In the middle proposition of patent " detaching structure of hydraulic type spindle breaker " (201220715992.2) in lower bearing bracket method
Four holes are dug on blue face for installing jack, upper spider are directly opened, strength reduction degree of such form to lower bearing bracket
It is excessive, and can not be used when upper and lower straightening machine frame is installed, not in view of crusher uses overlong time, and it is viscous to generate flange face up and down
Resultant force surrounding is unevenly distributed, and opens cause to damage to upper and lower straightening machine frame flange face by force.
The dismounting mode proposed in patent " a kind of compound single-cylinder hydro cone-crusher " (201710042434.1),
The disassembly and installation of upper and lower straightening machine frame is driven using the mode of piston rod, however it remains following 2 point defect: 1. equipment are in use process
In there may be getting rusty, cause the removal force that every side needs in disassembly process different, if each side use it is identical
Power goes to dismantle, and the flange distortion that may cause upper spider makes host integral inclined or damage provision for disengagement itself.2. tearing open
During unloading feedback can not be monitored to disassembly situation.
Summary of the invention
To solve the above problems, the present invention provides a kind of dismounting of Single-Cylinder Hydraulic Cone Crusher upper spider to fill
It sets, using the device, the personnel and time cost for dismounting upper spider are greatly reduced, and power source is just equipped with hydraulic for equipment itself
It stands, when dismounting can be automatically adjusted by feedback system, so that whole process reaches steadily, save space and cost.
The present invention is realized by following technical proposals.A kind of Single-Cylinder Hydraulic Cone Crusher upper spider attaching/detaching apparatus, packet
