The lifting device does not need to use a hoisting tool, has simple structure and convenient carrying and operation, prevents operating staff from being hurt in the construction process, also simultaneously reduces labor intensity, improves working efficiency and greatly lowers the overhauling cost.
Description
Technical field
The utility model relates to a kind of transformer main transformer fan electromotor maintenance lowering or hoisting gear.
Background technology
Along with the progress of science and technology, big motor is widely used in transforming plant main transformer wind-cooling heat dissipating device, the long-term operation continuously of fan electromotor, the as easy as rolling off a log electrical fault that causes, in addition, according to the requirement of main transformer fan electromotor service technique rules, annual reply main transformer fan electromotor carries out a dismounting overhaul.At present, when carrying out the overhaul of main transformer fan electromotor, because of the setting height(from bottom) of motor generally about 1.8 meters, generally adopt manpower to praise the mode dismounting, perhaps adopt crane sus-pension dismounting fan electromotor, make the fan electromotor turnover job have following problem:
The one, the main transformer fan electromotor owing to heavily about more than 100 kilograms of motor, uses too much, both consuming time, the consumption worker of manpower when praising the mode dismounting, and labour intensity is big again, inefficiency.
The 2nd, the main transformer fan electromotor adopts manpower to praise dismounting, very easily causes the workmen to damage, and has bigger potential safety hazard.
The 3rd, for the main transformer fan electromotor of 110 kv substations, because the part motor is subjected to the restriction of installation site and charged distance, during the dismounting overhaul, often need main transformer power failure back is adopted the mode dismounting motor of crane lifting, like this, not only influence the power supply reliability of electrical network, but also increased the cost of overhaul.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and is easy to operate, increases work efficiency, and reduces labour intensity, avoids the transformer main transformer fan electromotor maintenance lowering or hoisting gear of personal injury.
For achieving the above object, the technical solution adopted in the utility model is: a kind of transformer main transformer fan electromotor maintenance lowering or hoisting gear, comprise lifter, the bottom of described lifter is fixedly mounted on the inspection platform, the upper end of lifter be connected be used to prop up the pallet of waiting to repair motor, the lower surface of inspection platform is provided with rack leg.
The maintenance of above-mentioned transformer main transformer fan electromotor is used lowering or hoisting gear, the both sides of described pallet to be provided with to be used for the fastening fastening chain of waiting to repair motor.
Lowering or hoisting gear is used in above-mentioned transformer main transformer fan electromotor maintenance, and described rack leg is connected with inspection platform is hinged.Purpose is to be convenient to transportation.
It is the hydraulic up-down device that lowering or hoisting gear, described lifter are used in above-mentioned transformer main transformer fan electromotor maintenance, perhaps spiral lifter, perhaps chain-type lifter, perhaps pinion and-rack lifter.
It is arc pallet or dull and stereotyped pallet that lowering or hoisting gear, described pallet are used in above-mentioned transformer main transformer fan electromotor maintenance.When the fan electromotor level is installed, use dull and stereotyped pallet, when fan electromotor is vertically installed, use arc pallet.
The beneficial effects of the utility model are: adopt the bottom of lifter to be fixedly mounted on the inspection platform, the upper end of lifter be connected be used to prop up the pallet of waiting to repair motor, the lower surface of inspection platform is provided with rack leg.Can when the maintenance fan electromotor, pallet be risen to the position of waiting to repair fan electromotor, the dismounting fan electromotor, and place on the pallet, be reduced to rational maintenance position again, overhaul, after maintenance finishes, again fan electromotor is risen to the installation site.Easy to operate, save manpower, the injury that shuns labor is increased work efficiency, and simultaneously, need not use lifting device, saves recondition expense.
Adopt the both sides of pallet to be provided with and be used for the fastening fastening chain of waiting to repair motor, can fastening motor to be repaiied, avoid in lifting process, rolling.
The utility model is simple in structure, convenient in carrying.The injury of having avoided the operating personnel to be subjected in work progress also reduces labour intensity simultaneously.Greatly reduce the cost of overhaul.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Description of drawings
Fig. 1 is that the utility model master looks schematic diagram;
The fastening chain 2-of mark among the figure: 1-pallet 3-lifter 4-inspection platform 5-rack leg.
Embodiment
As shown in Figure 1, a kind of transformer main transformer fan electromotor maintenance lowering or hoisting gear, comprise lifter 3, the bottom of described lifter is fixedly mounted on the inspection platform 4, the upper end of lifter be connected be used to prop up the pallet 2 of waiting to repair motor, the lower surface of inspection platform is provided with rack leg 5.The both sides of pallet are provided with and are used for the fastening fastening chain 1 of waiting to repair motor.Rack leg is connected with inspection platform is hinged, so that folding and transportation.
Lifter is the general hydraulic up-down device that adopts, and also can be spiral lifter, perhaps chain-type lifter, perhaps pinion and-rack lifter.To save cost, improving lifting efficient is standard.
Pallet is arc pallet or dull and stereotyped pallet.When the fan electromotor level is installed, use dull and stereotyped pallet, when fan electromotor is vertically installed, use arc pallet.
During use, pallet 2 is placed on inspection platform 4 corresponding to the motor of needs maintenance the below of motor, operation lifter 3 makes closely contact main transformer fan electromotor air duct of pallet 2, utilize fastening chain 1 that fan electromotor is fixedly secured on pallet 2 then, pull down the set bolt and the motor down-lead of fan electromotor base, operate lifter 3 again and make pallet and motor at the uniform velocity reduce to inspection platform 4.To the fan electromotor overhaul of disintegrating, after maintenance finishes, operate lifter 3 again motor is installed to the fan electromotor installation site then, promptly finish the service work of fan electromotor.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
