Description
Technical field
The present invention relates to plant equipment to overhaul field, more particularly to a kind of restricted clearance Large-scale Horizontal Hydraulic Cylinder dismounting side
Method.
Background technology
All kinds of large_sized hydraulic cylinders are visual plants indispensable in metallurgy industry production, and hydraulic cylinder was frequently using
Cheng Zhong, plunger rod, seals and other component in hydraulic cylinder body inevitably wear and damaged, hydraulic cylinder is opened and inspect in time and
Maintenance, it is to ensure that the necessary link of hydraulic test routine safety operation.In the opening and inspecting and repair of large_sized hydraulic cylinder, by tens of tons
Hydraulic cylinder pulled down from support and hydraulic cylinder repair after be reinstalled support, be the important work of hydraulic press maintenance work
The requirement of sequence, work load and safe construction is all very high.
Dismounting of the dismounting of restricted clearance Large-scale Horizontal Hydraulic Cylinder different from open type vertical solution cylinder pressure.Vertical solution cylinder pressure
Dismounting need to only complete the dismounting of hydraulic cylinder by the vertical lift of separate unit hoisting machinery；The dismounting of horizontal hydraulic cylinder must be in lifting
Under the supporting of machinery, the dismounting of hydraulic cylinder is completed by the horizontal displacement of hydraulic cylinder.
In the case of not having hoisting facilities at the scene, the traditional method torn open or filled of restricted clearance horizontal hydraulic cylinder is：
More hoist cranes are set above hydraulic cylinder, is passed and connect by the multiple handling of hoist crane, realizes and hydraulic cylinder is pulled out or put into
Hydraulic press support, and hydraulic cylinder is removed or moved into hydraulic cylinder works room.In disassembly process, hydraulic cylinder suspends feelings in midair in hoist crane
Carry out passing under condition connecing displacement.To avoid in passing and connecing shifting process, because hoist cable horizontal sextant angle is excessive and caused by hoist crane overload
Situation, it is only 1.5-2 rice to pass connect the distance of displacement every time, and what whole disassembly process need to repeatedly convert hoist crane hangs position
Put, therefore traditional handling is passed and connects assembly and disassembly methods, labor intensity is big, work efficiency is low, and this is special in hydraulic cylinder works room
Operation is carried out in working region, because ground spreads all over machine oil, more potential safety hazard be present, injury accident easily occurs.

The position accuracy demand that bar 23 is set is very high, once minor deviations occur for position, during traction rolling fortune, the side of gib block 23
One is formed to the rolling fortune direction with supporter roller 20 and hinders angle α, and now gib block, must into the stopper of supporter roller rolling fortune
So occur that tractive force is increasing, supporter roller can deviate the phenomenon of hydraulic cylinder.Therefore, in the present invention, the rolling fortune platform 2
Top surface do not limit the horizontal plane of the direction of motion of supporter roller 20 preferably, only rely on support hole and the movement locus of hydraulic cylinder 1 entered
Row limitation, it is easy to the smoothly rolling fortune of hydraulic cylinder 1.The rolling fortune platform 2 can use steel platform.
In the present invention, when hydraulic cylinder 1 is rolling fortune on rolling fortune platform 2, it is necessary to by motion rail of the support hole to hydraulic cylinder 1
Mark is limited, it is ensured that will not be offset during the rolling fortune of hydraulic cylinder 1 to both sides, therefore, hydraulic cylinder 1 on rolling fortune platform 2 when rolling fortune, institute
Hydraulic cylinder 1 is stated without departing from support 5；When hydraulic cylinder 1 is rolling fortune on rolling fortune guide rail 3, it is small that rolling fortune is limited by rolling fortune guide rail 3
The moving direction of car 30 so that hydraulic cylinder 1 will not left and right skew, smoothly depart from restricted clearance.
In summary, the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe
Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete without departing from disclosed spirit and institute under technological thought such as
Into all equivalent modifications or change, should by the present invention claim be covered.
