Abstract

The invention discloses a transformer rack assembling method which employs an embracing hoop. The method comprises the following steps: 1, embracing and sleeving two hoop plates on an auxiliary pole, clamping U-bars with corresponding thickness between long ears of the two hoop plates; 2, placing the long ears on the both outsides of the auxiliary pole, then locking the two hoop plates by a bolt connection piece connected and fixed on the two hoop plates, the connecting piece being used for detaching locking mechanism, 3, arranging two mounting clamp plates which are used for bearing the transformer at the two sides of the auxiliary pole and a main pole, and arranging the two mounting clamp plates on the two long ears of the hoop plates in a clamping manner. The embracing hoop applied to the auxiliary pole mounting of the transformer and the transformer rack assembling method have the advantages that the structure is simple, the difficulty of mounting is reduced, the effective mounting can be carried out in a manner that the situation that the circular diameter gap of the two poles is large is overcome, and the requirements on the mounting and designing are better met.

Description

Adopt the transformer stand assembly method of anchor ear
Technical field
The present invention relates to transformer stand installing component and installation method technical field, relate in particular to a kind of transformer stand assembly method that adopts anchor ear.
Background technology
No matter distribution aerial pole is that partial prestressing bar or double ender all generally adopt tapered rod at present, and it has durable stability height and lightning-arrest feature.But also produce a problem simultaneously, for same tapered electric pole, its installation site difference, electric pole radius is also different; Make distribution transformer actual installation practice on to overhead wire, run into certain trouble.
Meeting under the prerequisite of transformer mounting design requirement, transformer is installed.As depicted in figs. 1 and 2, transformer 3 is installed and is needed 2 electric poles, is called mobile jib 2 and secondary bar 1.Support overhead transmission line and be called mobile jib 2, mobile jib 2 models are selected according to relevant design principle, adopt slightly footpath all at ¢ more than 190.General secondary bar employing electric pole slightly footpath is the prestressed concrete electric pole of ¢ 190, and height is low compared with mobile jib.Therefore same position, the circular diameter of mobile jib is than secondary bar circular diameter large (common mark footpath, secondary bar installation site is that ¢ 270, ¢ 290, mark footpath, mobile jib installation site are ¢ 370, ¢ 400, ¢ 420), while causing distribution transformer stand to be fixed on two electric poles with two or four as the channel-section steel that clamping plate are installed, fixed installation position is trapezoidal or rectangle.And transformer base track installation site is generally rectangle, its rectangle has certain adjustable range, carrys out adaptive deformation.As shown in Figure 2, does not mate with transformer base track installation site channel-section steel installation site, is divided into following three kinds of situations:
1. liang electric pole circular diameter gap is little, and trapezoidal deformation is little, by transformer base track position adjustments is installed, without any measure of additional employing again.
2. liang electric pole circular diameter gap is larger, and trapezoidal deformation is larger, exceeds transformer base track position adjustments scope.Can adopt at secondary bar increase common anchor ear as shown in Figure 3, increase secondary shank diameter by the wall thickness of anchor ear, reduce the diameter gap of two electric poles, then by transformer base track position adjustments is installed.
3. liang electric pole circular diameter gap is large, trapezoidal deformation is large, transformer installation difficulty is large, easily sliding stability is poor, not attractive in appearance, the most important thing is not reach the requirement of transformer mounting design, check and accept and do not pass through, cannot install transformer by transformer base track being regulated and increasing the measures such as parallels and existing anchor ear.
Therefore, those skilled in the art is devoted to develop one can overcome above-mentioned defect, simple in structure, reduce installation difficulty, can overcome the large situation of above-mentioned two electric pole circular diameter gap and effectively install, more meet that mounting design requires for transformer, anchor ear and the transformer stand assembly method on secondary bar is installed.
Summary of the invention
Because the above-mentioned deficiency of prior art, the present invention be propose a kind of simple in structure, reduce installation difficulty, can overcome the large situation of above-mentioned two electric pole circular diameter gap and effectively install, more meet the transformer stand assembly method of the employing anchor ear that mounting design requires.
For achieving the above object, the invention provides a kind of transformer stand assembly method that adopts anchor ear, described anchor ear comprises the identical hoop plate that is all semi arch band shape of two block structures, after binding round plate obvolvent described in two, be ring-band shape, also comprise for binding round plate described in two and be locked in the detachable retaining mechanism of obvolvent state, wherein, the two ends of described hoop plate is extended the screech owl for increasing secondary bar bar footpath that is symmetrically arranged with the plane that exists together laterally, described in two, bind round between the screech owl of plate and be respectively provided with a cushion block, described detachable retaining mechanism is locked in obvolvent state by screech owl and cushion block by binding round plate described in two, described cushion block is channel-section steel, described detachable retaining mechanism is bolt connection piece, is provided with the installing hole for described bolt connection piece is installed on described screech owl and cushion block, described transformer stand assembly method comprises the following steps:
Step 1: two hoop plate obvolvents are set on secondary bar to the channel-section steel of sandwiched respective thickness between the screech owl of two hoop plates;
Step 2: described screech owl is placed in to described secondary bar two outsides, then by being connected and fixed the bolt connection piece locking two hoop plates as detachable retaining mechanism on two screech owls;
Step 3: be arranged on the both sides of described secondary bar and described mobile jib for carrying the installation clamping plate of transformer by two, described in two, mounting clamp plate holder is located on two screech owls of described hoop plate.
Anchor ear and transformer stand assembly method of installing on secondary bar for transformer of the present invention has following beneficial effect:
Hooping structure of the present invention simple, the secondary bar that is suitable for different situations convenient, can be wider is installed needs is installed, can, by adding by clamping plate are installed the secondary bar bar of the increase footpath of strengthening on screech owl, overcome the large situation of above-mentioned two electric pole circular diameter gap and effectively install.
With bolts as detachable mechanism and channel-section steel as cushion block, can strengthen anchor ear and be subject to force intensity and strengthen stability, further facilitate both sides simultaneously the installation of clamping plate and fixing be installed.
3. transformer stand assembly method of the present invention adopts anchor ear of the present invention to be arranged on secondary bar, in the time that the bar footpath of secondary bar and mobile jib gap is little, can adopt anchor ear or according to the usage of common anchor ear, clamping plate is directly installed on the outside of anchor ear; And in the time that the bar footpath of secondary bar and mobile jib gap is larger, can be by rotating anchor ear of the present invention to both sides, come the bar footpath of the secondary bar of larger increase by the length of screech owl, realize the convenient installation of transformer stand.
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.
