Description
Technical field
A kind of large-scale dismountable lower end axle inspection platform is the utility model is related to, belongs to maintenance auxiliary equipment technology neck
Domain.
Background technology
Large-sized water turbine generator lower end shaft diameter is mostly more than 2 meters, height be mostly 5 meters or so, weight typically 100 tons with
On, it is that generator and the hydraulic turbine are directly connected to part, when lifting is repaiied in lower end repacking, traditional approach is before lower bearing bracket is hung, first
The suspender of lower end axle is hung in installation, then is being placed above at rope ladder to water wheel chamber water Oil Guide tank cover plate, after lower bearing bracket is hung out, maintenance
The rope ladder top that personnel need to climb up 10 meters or so mounts steel wire rope to lower end axle, this process unprotect special hazard, overhauls
Cheng Zhong, the safety belt that maintainer wears, can only be by the safety belt systems of maintainer's wearing on a steel cord, separately without fixed hanging point
Steel wire rope is held at one maintainer station at generator floor, and whole maintenance process is held steel wire rope by manpower and protected, dangerous
Coefficient is big, and due to the limitation of lower end shaft flange face position, can only get on two maintainers, and operating efficiency is slow.
In summary, original lower end repacking repaiies that protective equipment complex operation, danger coefficient are big, operating efficiency is low.
Utility model content
The technical problems to be solved in the utility model is：A kind of large-scale dismountable lower end axle inspection platform, maintenance are provided
Platform has a safety belt hanging point, and platform can provide the working space of 5 people while maintenance, and repairing protection to solve original lower end repacking sets
Standby complex operation, danger coefficient be big, ineffective problem, and inspection platform is sling by special hanger, can go up downward during maintenance
Whole position, in addition, inspection platform dismounting, easy for installation, easy to remove and keeping.
The technical solution of the utility model is：A kind of large-scale dismountable lower end axle inspection platform, including it is workbench, interior
Guard rail and outer guard rail, the workbench are spliced by bearing plate, and interior guard rail is connected with workbench, outside
Guard rail is connected with workbench, and workbench is toroidal.
Preferably, sling during above-mentioned inspection platform work by special hanger, Awaiting Overhaul lower end axle is placed in the circle of workbench
In the inner ring of ring-shaped.
Preferably, the bearing plate of above-mentioned workbench can be aluminium sheet, steel plate or plastic-steel board, and quantity can be 3-10 blocks.
Preferably, above-mentioned interior guard rail and outer guard rail are made up of fender rod and guard ring.
Preferably, the both ends of above-mentioned fender rod are screw-rod structure, and workbench and guard ring are provided with through hole, respectively with preventing
Guard bar is connected with.
The beneficial effects of the utility model are：A kind of large-scale dismountable lower end repacking equating of the utility model design
Platform, inspection platform have safety belt hanging point, and safety belt is hung over fender rod and guard ring bolt connection position, safety system by maintainer
Number is high, to solve the problems, such as prior art safety belt without safe hanging point；Platform can provide the working space of 5 people while maintenance, work
Make efficiency high, having solved prior art 2 people while can only overhaul, and the problem of need other 2 people to do security protection；Inspection platform by
Special hanger is sling, during maintenance can upper and lower adjustment position, to solve to do upper-lower position by manually pulling loose steel wire rope in the prior art
The potential safety hazard of adjustment and operation inconvenience, in addition, inspection platform dismounting, easy for installation, easy to remove and keeping.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model；
In figure：1st, workbench, 2, interior guard rail, 3, outer guard rail, 4, fender rod, 5, guard ring.
Embodiment
Below in conjunction with the accompanying drawings and utility model is described further specific embodiment：
With reference to figure 1 and Fig. 2, a kind of large-scale dismountable lower end axle inspection platform of the utility model, including workbench 1,
Interior guard rail 2 and outer guard rail 3, the workbench 1 are spliced by bearing plate, and interior guard rail 2 uses bolt with workbench 1
Connection, outer guard rail 3 are connected with workbench 1, and workbench 1 is toroidal, and the bearing plate of splicing is easy to disassemble,
Bolt connection is firm, and assembly and disassembly is convenient.
Sling during above-mentioned inspection platform work by special hanger, Awaiting Overhaul lower end axle is placed in the toroidal of workbench 1
Inner ring in, adjustment position above and below suspender can be passed through during maintenance.
The bearing plate of above-mentioned workbench 1 can be aluminium sheet, steel plate or plastic-steel board, and quantity is 3-10 blocks, preferably aluminium sheet, together
Under sample load-bearing conditions, aluminium sheet is in light weight, easy to remove；Quantity is very few to increase accommodation space and can be because bearing plate is overweight or excessive
Be inconvenient to dismantle, quantity can excessively increase the take-down time, while influence the stability of workbench.
Above-mentioned interior guard rail 2 and outer guard rail 3 are made up of fender rod 4 and guard ring 5, and fender rod 4 can play protection
The arbitrary shape of function.
The both ends of above-mentioned fender rod 4 are screw-rod structure, and workbench 1 and guard ring 5 are provided with through hole, respectively with fender rod
4 are connected with
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
