Embodiment
Hereafter in conjunction with the accompanying drawings and embodiments the utility model is described further.
With reference to Fig. 1-2, a kind of 10kV, 35kV switch gear room crane span structure lifting device, comprising: pulling part, support portion and sliding part;
Described pulling part comprises back(ing) bar 11 and pulling apparatus 12, and described pulling apparatus 12 is connected by U-shaped suspension ring 13 with the center of back(ing) bar 11;
Described support portion comprises the vertical support bar 21 be connected with the two ends of described back(ing) bar 11, and is connected to the horizontal brace rod 22 of described vertical support bar 21 end; Described horizontal brace rod 22 is provided with height-adjustable support chassis 23 and sliding part; Described support chassis 23 is connected with described horizontal brace rod 22 by a screw rod 24, rotates described screw rod 24, i.e. the height of support chassis 23 described in adjustable.When the height of described support chassis 23 is adjusted to earth surface, described sliding part is in surface separation; When the height of described support chassis 23 is adjusted to surface separation, described sliding part is in earth surface.In the present embodiment, described sliding part is pulley 27.Described support chassis 23 is arranged at two ends and the centre of described horizontal brace rod 22.
Inclined support bar 25 is provided with between described back(ing) bar 11 and vertical support bar 21; Gusseted bar 26 is provided with between described vertical support bar 21 and horizontal brace rod 22.
Described back(ing) bar 11 is bolted by three sections of suspension rods and forms; Described vertical support bar 21 is bolted by three sections of support bars and forms.Described three sections of suspension rods and three sections of support bars are respectively equipped with multiple bolt hole, are bolted different bolts hole, regulate the entire length of described back(ing) bar 11 and vertical support bar 21.Described pulling apparatus 12 is zipper calabash, and its one end connects a suspension hook 121.
During use, the height installed is needed according to crane span structure, back(ing) bar 11 and vertical support bar 21 are set to suitable length, first adjusting screw(rod) 24, make support chassis 23 and surface separation, after lifting device being moved to installation site by pulley 27, adjusting screw(rod) 24 makes support chassis 23 and earth surface, and whole device completes location.Be connected with crane span structure by the suspension hook 121 of zipper calabash, because slinger has 2, therefore the two ends of crane span structure are all by suspension hook 121 hook lock.Pulled by staff or electronicly pull zipper calabash, crane span structure can be promoted to the height of needs.
Therefore efficiency and the job security of work is substantially increased.Lifting device uses manual or electronic zipper calabash, and crane span structure rising, decline, location are all easily realized by lifting device, overcome the dangerous point only lifting fortune crane span structure by manpower.Conventional crane span structure rises, declines is all lift fortune by manpower, whole need of work 9-10 people; After using lifting device, personnel reduce to 6 people, and whole crane span structure is dismantled, installation process is light, simple, time saving and energy saving.In lifting device, each parts are designed to independent individual, and during use, connecting portion is screwed, and the used time is not detachable, conveniently carries and enters 10kV or 35kV switch gear room.Wherein back(ing) bar and vertical support pole length in lifting device, whole tool level are adjustable, and instrument is also by pulley easily movement, and whole instrument is flexible and changeable, and occasion installed by the different crane span structure of applicable 10kV and 35kV.
Change engineering for electric company 110kV western suburb, Guo Wang Longyan Substation No.1 main transformer 10kV inlet wire crane span structure, after using lifting device, the operating time decreases 2 hours 30 minutes.Be 1063A by the electric current of inlet wire bridge, within 2 hours 30 minutes, electricity √ 3 × 1063 × 10 × 103 × 0.8 × 2.5=3.68 × 104kWh can be carried, by the 0.5 yuan of calculating of 1 degree of electricity, then can retrieve the electric quantity loss of 1.84 ten thousand yuan.With regard to total nearly 10 bus bridge frames annual in the transformer station that Guo Wang Longyan our department of electric company administers (for 2013 06 month to 2014 06 month, western suburb, Longyan become 1, Longyan Huang Xi become 2, Shanghai-Hangzhou Gutian become 2, Yongding put down to become 2 in change 2, area just outside a city gate, Wuping, Longyan heavenly steed becomes 2) need to carry out dismantling and installing, then the company that can be every year creates indirectly 18.4 ten thousand yuan of economic benefits.Have 100 crane span structures every year by the whole province need dismounting and install, then can create the benefit of 1,840,000 yuan.As long as the whole province carries out 6 years, economic benefit just can break through 1,000 ten thousand yuan.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
