Abstract
The invention relates to a lifting device for replacing a transformer. The lifting device is structurally characterized in that a lifting steering shaft is sleeved in a lifting steering rod; one end of the lifting steering rod is inserted in a base and the other end of the lifting steering rod is connected with one end of a fixed traction steel rope; the other end of the fixed traction steel rope is fixed on a stayed pole in a penetrating-buckling manner; and a hoop is welded with the base. According to the invention, the construction intensity is reduced, both time and labour are saved, long-time and large-area power outage can be effectively avoided, economic benefits are brought for enterprises, the power supplying reliability of lines is improved, loss of users caused by outage can be effectively avoided, the working efficiency is improved, and fuel loss and environmental pollution caused by use of large-scale lifting appliances can be avoided.
Description
Technical field
The present invention relates to a kind of replacing device for transformer, relate in particular to a kind of replacing voltage transformer lifting appliance.
Background technology
Power supply reliability is relevant with a quality of power supply basic index, and its height not only is directly connected to the economic benefit of power supply enterprise, is more representing the service quality and the level of management of power supply enterprise.
From beginning in 2011, the S11 type amorphous alloy distribution transformer that novel energy-saving environment-friendly is puted forth effort to carry out by each Utilities Electric Co. more changed jobs.In 10 kilovolts of distributions, particularly the distribution transformer of rural power distribution online operation is the S7 type in addition greatly before, and high consumption low energy seepage is serious, and overload operation already.
Change in the early stage in the work of voltage transformer; The problem that runs into is: 1, geographic restriction the elevator machinery operation; With a varied topography, especially rural area platform district voltage transformer have in the vegetable garden, have in lane, being surrounded of having by obstacles such as silos, elevator machinery at all can't evolutionary operation; 2, circuit can not have a power failure and limit the operation of use elevator machinery, and like mine, hospital etc., teams and groups' power failure production plan delays again and again.
It is on the cross-arm of deployment line, to cost a beam that traditional voltage transformer is changed operational method, fixes chain block, lifts by crane behind the iron in the teardown stand.Construction intensity is big, many with duration, personnel, waste time and energy.Overcome the deficiency of these geographical conditions, circuit condition of service, mechanical work usage condition, improve the work efficiency problem of changing voltage transformer, become the task of top priority.
Summary of the invention
The present invention is directed to the problem that exists in the above-mentioned prior art, a kind of replacing voltage transformer lifting appliance is provided, solved and changed the problem that the voltage transformer construction intensity is big, waste time and energy in the prior art, and improved the power supply reliability of circuit.
Technical scheme of the present invention is following:
The lifting steering column jacket is loaded in the lifting deflecting bar, and an end of lifting deflecting bar inserts in the base, and the other end of lifting deflecting bar links to each other with an end of fixed traction steel cable; The other end of fixed traction steel cable is worn button and is fixed on the line bar; Anchor ear and base welding.
Described base is provided with the capping that prevents the slippage of lifting steering shaft.
Described fixed traction steel cable is provided with the turnbuckle of regulating its length.
The vertical angle of described lifting deflecting bar is 45 degree.
Advantageous effect of the present invention is following:
Reduce construction intensity; Time saving and energy saving; Can effectively avoid long-time, the large-area power-cuts operation of circuit, not only bring interests economically, improve the power supply reliability of circuit to enterprise; And can promote the status image of enterprise in the user, the loss that can effectively avoid the user to cause because of power failure; Can effectively solve on the other hand because of the geographic position influences and can't use mechanical work, a large amount of inputs of formed human and material resources when adopting the orthodox method operation, and can effectively increase work efficiency.The voltage transformer that adopts traditional operational method to change one 50 kilovolt-amperes needs personnel 10 people, and 2 hours times spent, equal conditions uses this device only to need 6 people down, and 30 minutes times spent can accomplish, and can promote accomplishing smoothly as scheduled of the rural power grids project of upgrading and rebuilding better.Applying of this device also can avoid the use of losses such as fuel oil that large scale hoisting machinery brings and to pollution that environment caused in addition.

Embodiment
Shown in Fig. 1-2, the lifting steering column jacket is loaded in the lifting deflecting bar 2, and an end of lifting deflecting bar 2 inserts in the base, and base is provided with the capping that prevents the slippage of lifting steering shaft; The other end of lifting deflecting bar 2 links to each other with an end of fixed traction steel cable 3 through shackle, and the vertical angle that fixed traction steel cable 3 is regulated lifting deflecting bar 2 is 45 degree; The other end of fixed traction steel cable 3 is worn button and is fixed on the line bar 8; Fixed traction steel cable 3 is provided with the turnbuckle of regulating its length; Anchor ear 1 and base welding, anchor ear are regulated to win in succession and are regulated length according to line bar 8 thicknesses.
The Work tool that is used comprises chain block 6 or two or three assembly pulleys, hand rope and spanner etc.
Use of the present invention is following:
On anchor ear 1 fixing online bar 8,, make anchor ear 1 fastening through regulating connecting plate and governing screw a little more than transformer platform 4.
The lifting steering column jacket is loaded in the lifting deflecting bar 2; The top of lifting deflecting bar 2 is with the corresponding height of fixed traction steel cable 3 fixing online bars 8; Through the length of turnbuckle adjusting fixed traction steel cable 3, thereby the vertical angle of adjusting lifting deflecting bar 2 generally is advisable with 45 degree.
After a side of transformer platform 4 winches to 5 of voltage transformers a little more than transformer platform 4, through fastening hand rope pulling lifting deflecting bar and the voltage transformer rotation on voltage transformer, voltage transformer is rotated to correct position on the transformer platform 4, crane lifting service finishes.
The present invention has carried out bearing test twice, has lifted by crane the voltage transformer of 50 kilovolt-amperes and 200 kilovolt-amperes respectively, and check has all been passed through in load-bearing.
Generally all below 100 kilovolt-amperes, load-bearing range of use of the present invention is set in the voltage transformer below 160 kilovolt-amperes to the transformer capacity of rural power grids at present, has satisfied the needs of changing.
