Abstract
The utility model belongs to the technical field of hoist frames, and discloses a hoist frame for detaching a main transformer fan. The hoist frame is characterized by comprising a vertical supporting rod and a cross rod which is positioned at the top end of the supporting rod and connected with the supporting rod; and the lower end of the supporting rod is provided with a base plate. When the hoist frame is used, the base plate is placed in an oil pool or on the ground, the supporting rod is adjusted to a height in line with a main transformer radiator, the cross rod is fixed on an oil collection box of the radiator in an overlap joint manner, and a rubber plate or a wood plate is lined below the cross rod to protect the radiator from being broken; and a fan to be replaced is lifted by lifting equipment which is fixed on the cross rod, so that the hoist frame is convenient to use, and the work efficiency is greatly improved. After the hoist frame for detaching the main transformer fan is used, labor of 2 to 3 workers for detaching one fan can be saved, the working time for detaching the fan can be shortened by 50 percent, and the fan can be replaced without stopping a main transformer.
Description
Technical field
The utility model belongs to the hoist frame technical field, relates to the dismounting of main transformer blower fan concretely and hangs a year hoist frame.
Background technology
According to incompletely statistics, in the 110KV main transformer of operation, the main transformer of air cooling way accounts for about 3/4ths; The main transformer blower fan belongs to the rotating machinery of long-term operation, and maintenance maintenance amount is big, and the blower fan dismounting of installing for the side is difficult; The main people's half the circumference of the sleeve where it joins the shoulder that leans on is anti-, or uses crane lifting, and labor content is big; Have the danger, the hidden danger that injure personnel by a crashing object many, because safety distance is not enough, the part blower fan must just can carry out dismounting and maintenance when main transformer has a power failure.
The utility model content
The technical matters that the utility model solves just provide a kind of can dismounting main transformer blower fan under situation about not having a power failure, in light weight, volume is little, use the main transformer blower fan dismounting of conveniently moving, high efficiency to hang carries a hoist frame.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise vertical strut bar be positioned at supporting bar top and with this strut bar bonded assembly cross bar, be provided with the chassis in the lower end of said strut bar.
Its additional technical feature is:
Said strut bar is a telescope.
The main transformer blower fan dismounting that the utility model provides is hung and is carried a hoist frame, and comparing with prior art has the following advantages: one of which since comprise vertical strut bar be positioned at supporting bar top and with this strut bar bonded assembly cross bar; Lower end at said strut bar is provided with the chassis, and put to oil sump or ground on the chassis during use, and strut bar is adjusted to and main transformer radiator level height; Cross bar overlap joint is fixed on the radiator oil box, and line with rubber plate or plank below are to prevent bad radiator of chromium; Blower fan to be replaced is through being fixed on the hanging device lifting on the cross bar, uses conveniently, and work efficiency improves greatly; After using the dismounting of main transformer blower fan to hang year hoist frame; Dismounting one typhoon machine can reduce personnel 2-3 people, and work-hours shortens 50%, and can carry out blower fan and change not stopping main transformer; Its two because said strut bar is telescope, can be as required the height of adjustable support bar arbitrarily, field of application is wider.
Description of drawings
Fig. 1 hangs the structural representation that carries hoist frame for the dismounting of main transformer blower fan.
The specific embodiment
Below in conjunction with accompanying drawing the structure of carrying hoist frame being hung in the main transformer blower fan dismounting that the utility model proposed further specifies.
As shown in Figure 1, hang the structural representation that carries hoist frame for the dismounting of main transformer blower fan.Its structure comprise vertical strut bar 1 be positioned at strut bar 1 top and with this strut bar 1 bonded assembly cross bar 2, be provided with chassis 3 in the lower end of strut bar 1, put to oil sump or ground on chassis 3 during use; Strut bar 1 is adjusted to and main transformer radiator level height, and the cross bar overlap joint is fixed on the radiator oil box, below line with rubber plate or plank; To prevent bad radiator of chromium, blower fan to be replaced uses convenient through being fixed on the hanging device lifting on the cross bar; Work efficiency improves greatly, and after the dismounting of use main transformer blower fan was hung and carried hoist frame, dismounting one typhoon machine can reduce personnel 2-3 people; Work-hours shortens 50%, and can carry out blower fan and change not stopping main transformer.
Strut bar 1 is a telescope, by last intubate 11 be in the charge of 12 down and form, last intubate 11 and under be in the charge of 12 and have knock hole 13, be inserted with inserted link 14 in the knock hole 13, like this, the height of any adjustable support bar 1 as required, field of application is wider.
The protection domain of the utility model not only is confined to the foregoing description, and to carry the hoist frame structure identical as long as structure and the dismounting of the utility model main transformer blower fan are hung, and just drops on the scope that the utility model is protected.
Claims (2)
1. the dismounting of main transformer blower fan is hung and is carried a hoist frame, it is characterized in that: comprise vertical strut bar be positioned at supporting bar top and with this strut bar bonded assembly cross bar, be provided with the chassis in the lower end of said strut bar.
2. main transformer blower fan according to claim 1 dismounting is hung and is carried hoist frame, and it is characterized in that: said strut bar is a telescope.
