Description
Technical field
The present invention relates to transformer technical field of auxiliary equipment, and in particular to a kind of substation transformer back work is put down
Platform.
Background technology
Transformer station is the important node of electrical network, plays a part of to form a connecting link, and the normal operation of transformer station is largely
Depending on the normal operation of transformer.At present, volume of transformer is huge in extra-high voltage, Ultra-high Voltage Substations, some meters, valve
Door is located at the top of transformer, extremely inconvenient when maintenance, emergency first-aid repair, when maintainer places instrument, due to transformer
Lower section unload oil sump laid inside for cobblestone smooth texture and be uneven, it is impossible to lay firm, there is potential safety hazard.In addition
Cobblestone is even more wet and slippery on rainy day, easily causes personnel's tumble injury.
In order to Repair of Transformer, conveniently, staff desires to set up platform at the scene, it is contemplated that the complexity of surrounding
Situation and transformer it is high risk sexual, it is difficult to reserve permanent inspection platform on main transformer, so every time maintenance needs scene is set up
Scaffold could construct.But the reasons such as transformer device structure make scaffold construction there is problems with：1st, break and draw construction point lower section again
For transformer radiator and its pipeline, control system etc., there is cobblestone on ground, and common quick-installation scaffold is difficult to apply；2nd, multiple stage
Main transformer may be different with batch, or due to due to transformation, there is appearance and size, cooling system structure different, it is impossible to make one
General quick scaffold is covered, is such as fabricated separately according to each transformation, then make equipment purchase cost be multiplied；3rd, using steel pipe/
Although bamboo springboard scaffold cost is relatively low, flexible structure, there is limited bearing capacity, construction period length, easily transformer dissipated
Hot systems or sleeve pipe cause the defects such as damage.
The invention of Application No. 201210184052.X provide a kind of Repair of Transformer platform, it include connect base,
Grid pedal and stepped fastener, wherein, the grid pedal is made up of two pieces of transverse slats and polylith riser, the connect base bag

The plurality of stepped fastener is fixedly connected with the fixed dam in the connect base.The Repair of Transformer platform has
Design science, simple structure, firmly install, it is practical and improve job security advantage.But the invention can not be realized
Transport staff, maintenance Work tool and various parts up and down in upkeep operation.
A kind of substation transformer stone pit workbench of the disclosure of the invention of Application No. 201510538892.5, including hole
Supporting mechanism is set in base, transformer foundation and the stone being arranged in pit foundation, the pit foundation, steel is set on the supporting mechanism
Body panel, correspondence transformer is arranged and hangs derricking gear on the steelframe platform, and the suspension derricking gear lower section arranges level
Travel mechanism.Substation transformer stone pit is built into the present invention workbench of a steelframe, in the case where not affecting to insulating oil
Cause working environment more smooth in the case of oozing, be that service work increased facility beneficial to the superincumbent walking of staff
Property.And when to Repair of Transformer lifting movement can be carried out to concrete equipment or parts, it is not necessary to other lifting appliances
Carry out less important work, it is to avoid the potential safety hazard that the moving belt of large-scale boom hoisting comes in transformer station so that staff for
The repair and maintenance of transformer is convenient, also improves security during upkeep operation.But transformer is not considered in the invention
The complicated circuit on top, needs all to remove the circuit of top when in use, more bothers.
The content of the invention
Problem to be solved by this invention is to provide a kind of substation transformer auxiliary working platform, during to Repair of Transformer
Lifting movement can be carried out to concrete equipment or parts, it is not necessary to which other lifting appliances carry out less important work, it is to avoid become
The potential safety hazard that the moving belt of large-scale boom hoisting comes in power station.
To solve above-mentioned technical problem, the technical solution used in the present invention is：
A kind of substation transformer auxiliary working platform, including pit foundation, it is arranged on the transformer foundation at the pit foundation center, described
On the basis of the steelframe platform that arranges of the transformer that arranges and pit foundation top, the transformer surrounding arranges cell body, described
Cover plate mechanism for auto is set on cell body, and the lower section of described cell body one end arranges the elevating mechanism for driving the cover plate mechanism for auto, the lifting
