Description
Technical field
The utility model relates to a kind of auxiliary devices of bell-type annealer coil bases maintenance, belong to metal heat treatmet technology neck
Domain is specifically a kind of bell-type annealer coil bases apparatus for examination and repair that can do cold conditions leakage test.
Background technique
Bell type annealing furnace is a kind of metallurgy, the common heat treatment equipment of machinery industry, generally by hydrogen or hydrogen nitrogen when use
Mixed gas injects the confined space between inner cover and table as protective gas and heat conductor, because hydrogen is with inflammable, easy
Quick-fried characteristic, therefore, bell type annealing furnace must carry out cold conditions leakage test before coming into operation.Bell type annealing furnace is by high for a long time
Temperature operation will cause inner cover and table inner wall and be thinned, and inner cover and be covered on during frequent handling outside, it may occur that collide with to make interior
Cover and table deform, along with cooling tube or air inlet pipe, exhaust pipe leakage and motor and table poor sealing effect etc. because
Element will lead to the failure of cold conditions leakage test.In general, because table factor causes the probability of leakage test failure maximum, this
Just table need to be hung out dismantling to overhaul, then be assembled again, and carry out cold conditions leakage test, until being sealed by cold conditions
Test just can be carried out annealing operation.This table repair method is disadvantageous in that:, need to be by table after the completion of table maintenance
It transports back to original position, after installing coil of strip, buckling well inner cover, carries out cold conditions leakage test, once it is underproof cold conditions leakage test occur
Situation need to sling again inner cover, hang out coil of strip, repair again to table, reduce the overhaul efficiency of table, affect life
Produce rhythm.
Summary of the invention
It is easy to use the purpose of this utility model is to provide a kind of structure is simple, suitable for bell-type annealer coil bases
Service work can carry out cold conditions leakage test immediately after the completion of maintenance, prevent from reprocessing, and that improves overhaul efficiency can do cold conditions
The bell-type annealer coil bases apparatus for examination and repair of leakage test.
In order to reach the goals above, technical solution adopted in the utility model is: this is a kind of to do cold conditions leakage test
Bell-type annealer coil bases apparatus for examination and repair, including workbench, universal wheel and mobile platform, the bottom of mobile platform is equipped with universal
Wheel, it is characterised in that: be fixed with clack box on the side wall of the workbench, clack box is equipped be connected to hydraulic tube hydraulic and connects
Mouth, the nitrogen interface being connected to nitrogen tube and the cooling water connector being connected to cooling water pipe；The top of the workbench is equipped with
The right side wall of upper through-hole, workbench is equipped with side through hole；It is uniformly distributed on the mobile platform and is fixed with four cylinders, four
The piston rod of a cylinder is separately fixed at the four corners of supporting plate, and cylinder is connected with air pump.
The utility model has the beneficial effects that: structure is simple, easy to operate, the maintenance suitable for bell-type annealer coil bases
Work, can carry out cold conditions leakage test immediately after the completion of maintenance, prevent from reprocessing, avoid repeated work, time saving and energy saving, reduce
Labor intensity, improves overhaul efficiency.
Detailed description of the invention
Fig. 1 is the structure front-view schematic diagram of the utility model.

Specific embodiment
Referring to Fig.1, Fig. 2, Fig. 3 make the utility model.A kind of bell-type annealer coil bases that can do cold conditions leakage test
The bottom of apparatus for examination and repair, including workbench 1, universal wheel 4 and mobile platform 5, mobile platform 5 is equipped with universal wheel 4, in favor of movement
The walking of platform 5 and position are adjusted, it is characterised in that: are fixed with clack box 3 on the side wall of the workbench 1, are set on clack box 3
There are the hydraulic interface being connected to hydraulic tube 8, the nitrogen interface being connected to nitrogen tube 9 and the cooling water connector being connected to cooling water pipe
10, medium needed for hydraulic interface 8, nitrogen interface 9 and cooling water connector 10 provide cold conditions leakage test；The workbench 1
Top be equipped with upper through-hole 11, in favor of the maintenance to table, the right side wall of workbench 1 is equipped with side through hole 2, in favor of movement
The inner cavity of the disengaging workbench 1 of platform 5；It is uniformly distributed on the mobile platform 5 and is fixed with four cylinders 6, four cylinders 6
Piston rod is separately fixed at the four corners of supporting plate 7, and cylinder 6 is connected with air pump, by the synchronization lifting of four cylinders 6,
To adjust the height of supporting plate 7, conducive to the installation of equipment.
It when using the utility model, by the table handling of bell type annealing furnace and is placed on the upper face of workbench 1, carries out
The maintenance and replacement operation of table accessory transport the motor of bell type annealing furnace and are placed on supporting plate 7 after completing table maintenance
On, then mobile platform 5 is sent to lower section that is intracavitary to workbench 1, and being located at upper through-hole 11 from side through hole 2, operation cylinder 6 rises
Supporting plate 7 makes the motor on supporting plate 7 be increased to table bottom, and motor and impeller are mounted on table and are sealed place
Reason, is then log out mobile platform 5.It, will be on hydraulic, nitrogen, cooling water pipeline and the clack box 3 on table after motor is installed
Hydraulic interface 8, nitrogen interface 9 and cooling water connector 10 are correspondingly connected with, then after inner cover is hung to table designated position, are started hydraulic
Clamp locking.After completing above-mentioned preparation, the rotation of motor impeller is opened, cooling water is opened, by nitrogen interface 9 toward furnace
Confined space supplying nitrogen between platform and inner cover closes nitrogen, observation pressure is within a certain period of time when reaching certain pressure
Whether pressure change meets the requirements.It such as meets the requirements, then discharges nitrogen and carry out subsequent job.If pressure change goes beyond the scope, then
Repeat to detect, after validation test failure, sling inner cover and carry out hidden troubles removing, maintenance, experiment work, until cold conditions sealing examination
Test qualification.Finally, the table after inner cover, motor and maintenance is hoisted to bell type annealing furnace assembling, into normal operation.
