Referring to figs. 1 to Fig. 4, in this preferred embodiment, a kind of maintenance system for reducing vacuum chamber minimum sling height,
Insertion tube including being set to maintenance area in workshop replace system 1, vacuum chamber maintenance system 2 and vacuum chamber baking system 3 and
The fixed platform 43 for standing for maintenance personal being fixed on 4 lateral wall of vacuum chamber, wherein
Insertion tube replacement system 1 includes that insertion tube is replaced platform 11, is used for what insertion tube replacement platform 11 was fixedly connected
(tapping refers to that, for placing the round hole of vacuum chamber 4 on insertion tube replacement platform 11, insertion tube replacement platform 11 is for platform aperture
The ring structure of intermediate aperture) security protection insertion tube replacement railing and insertion tube more changing device, vacuum chamber maintenance system 2
Including the vacuum for platform aperture security protection being fixedly connected by vacuum chamber maintenance platform 21, with vacuum chamber maintenance platform 21
Railing and vacuum chamber maintenance unit are repaired in room, and vacuum chamber baking system 3 includes that vacuum chamber baking platform 21 and vacuum chamber toast
The vacuum chamber for platform aperture security protection that platform 21 is fixedly connected toasts platform railing and apparatus for baking 32；Insertion tube
It is 2.5- that replacement platform 11, vacuum chamber maintenance platform 21 and vacuum chamber baking platform 21, which are provided with one layer and its height,
4.5m；Insertion tube more changing device is fork truck.
It because vacuum chamber 4 is in maintenance, need to be lifted by crane, and its lower supporting leg 42 is placed on the support 5 of maintenance platform.This
In embodiment, fork truck (fork truck forks vacuum chamber 4, and it is highly low from the ground) is set by insertion tube more changing device, is additionally inserted into pipe
It replaces platform 11, vacuum chamber maintenance platform 21 and vacuum chamber baking platform 21 is provided with one layer and its height is set as 2.5-
3.5m, while the upper area of vacuum chamber 4 being provided with fixed platform 43, therefore, pass through fixation on the top of maintenance vacuum chamber 4
Platform 43 repairs, and at the middle part of maintenance vacuum chamber 4 and bottom by maintenance platform, therefore, this maintenance system is opposite
In existing maintenance system because one layer of maintenance platform is only arranged in it, therefore it can reach the purpose for reducing minimum sling height.
Further, guard rail 44 is welded in fixed platform 43.Fixed platform 43 includes by the outside of vacuum chamber cylinder
Wall toward more girders of external radiation, the secondary beam for connecting more girders, the platform board that is fixed on the frame that girder and secondary beam are formed,
Guard rail 44 is welded on secondary beam.
In addition, being at least arranged on insertion tube replacement platform 11, vacuum chamber maintenance platform 21 and vacuum chamber baking platform 31
There are the stair 7 for being used to connect fixed platform on vacuum chamber, the opening for docking with stair 7 offered on guard rail 44,
The dodge gate being flexibly connected with guard rail 44 is installed, dodge gate opens or closes opening when opening and closing in the opening.At least
Be provided with one and refer to for connecting the stair 7 of fixed platform on vacuum chamber: when folding stair is arranged, insertion tube replaces platform
11, vacuum chamber maintenance platform 21 and vacuum chamber baking platform 31 can share a stair 7.When for fixed stair, it is disposed adjacent
Insertion tube replacement platform 11 and vacuum chamber maintenance platform 21 can share a stair and may also set up two stair 7, and be spaced farther away
Vacuum chamber baking platform 31 then needs that a fixed stair are separately provided.Maintenance personal can enter the fixation of vacuum chamber 4 by stair 7
Platform 43, to repair.
Further, insertion tube replacement platform 11, vacuum chamber maintenance platform 21 and vacuum chamber baking platform 31 share same
The height of one platform, i.e. insertion tube replacement platform 11, vacuum chamber maintenance platform 21 and vacuum chamber baking platform 31 is arranged to phase
Same and interconnection.
In addition, when vacuum chamber 4 is monoblock type vacuum chamber, being provided with lower branch in the lower section of vacuum chamber 4 referring to Fig. 3 and Fig. 4
Leg 42, when repairing vacuum chamber 4, the lower supporting leg 42 of monoblock type vacuum chamber is placed on the support 5 of maintenance platform.Because existing whole
Body formula vacuum chamber is provided with upper supporting leg 41 and descends supporting leg 42 without being arranged, when upper supporting leg 41 is placed in the support 5 of maintenance platform,
Maintenance platform height is arranged the higher bottom end that just can guarantee vacuum chamber 4 and ground and keeps certain distance, to facilitate maintenance.And this reality
It applies in example, because being provided with lower supporting leg 42 in the lower section of vacuum chamber 4, therefore the height of maintenance platform can reduce, to reduce vacuum
The minimum sling height of room 4.
It is dried when the lower supporting leg 42 of vacuum chamber 4 is placed in insertion tube replacement platform 11, vacuum chamber maintenance platform 21 or vacuum chamber
When on the support 5 of roasting platform 31, the bottom end of vacuum chamber 4 is at a distance from ground less than 1 meter.By the bottom end of vacuum chamber 4 and ground
Distance controlling is within 1 meter, to guarantee that maintenance personal can carry out the bottom servicing operation of vacuum chamber 4 on ground.
Referring to Figures 1 and 2, when vacuum chamber 4 is split type vacuum chamber, vacuum chamber maintenance platform 21 includes true for repairing
First maintenance platform 211 of 4 central region of empty room and the second maintenance platform 212 for repairing 4 bottom section of vacuum chamber.The
One maintenance platform 211 and the settable sustained height of the second maintenance platform 212, can also be not provided with sustained height.
It should be noted that insertion tube replaces system 1 and vacuum chamber maintenance system when vacuum chamber is monoblock type vacuum chamber
2 structures can be made equally, to realize that insertion tube replacement system 1 and vacuum chamber maintenance system 2 are exchanged, i.e., insertion tube is replaced
It can be carried out in vacuum chamber maintenance system.
The maintenance system for reducing vacuum chamber minimum sling height that the present embodiment proposes, because by insertion tube more changing device
It is set as fork truck, insertion tube replacement platform 11, vacuum chamber maintenance platform 21 and vacuum chamber baking platform 21 are provided with one layer
And its height is set as 2.5-3.5m, while the upper area of vacuum chamber 4 being provided with fixed platform 43, it is therefore, true in maintenance
The top of empty room 4 is repaired by fixed platform 43, passes through vacuum chamber maintenance platform at the middle part of maintenance vacuum chamber 4 and bottom
, therefore, this maintenance system relative to existing maintenance system because one layer of maintenance platform is only arranged in it, therefore can reach reduction most
The purpose of small sling height.Meanwhile this maintenance system also has the advantages that structure simple, small investment and easy to accomplish.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure transformation made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant technical fields,
Similarly it is included within the scope of the present invention.
