Abstract
The utility model belongs to the field of power transformer equipment, relates to a clamp of a power transformer iron core, and particularly relates to an anti-bending weight-reducing structure for an iron core clamp. A clamp body comprises a hoisting plate vertical to the bottom edge of the clamp, wherein both sides of the hoisting plate are provided with upper folding edges which are symmetrically arranged, and also provided with hoisting holes for hoisting the iron core; a through screw hole is formed in the center of the dividing line of the hoisting plate and each upper folding edge; and side screw holes are formed in both ends of the clamp body. The anti-bending weight-reducing structure is light in weight, high in bending strength, attractive in appearance and simple in technology, and is suitable for mechanical and large-scale production.
Description
Technical field
The utility model belongs to the power transformer apparatus field, relates to the folder of kind of power transformer iron core, specifically a kind of core clamping bending resistance loss of weight structure.
Background technology
Along with the development of power transformer industry, the specialized trend that has become a kind of industry development of making unshakable in one's determination.In manufacture process unshakable in one's determination, folder directly influences manufacturing cost and multinomial performance index unshakable in one's determination as the most important part of iron core.At present, in the folder that uses unshakable in one's determination with channel-section steel as main material, soldering part is more, the processing technology complexity, course of processing mechanization, automaticity is low, the production cost height, complex management is easily made mistakes.Other has the whole folder of monolateral bending, and technology is simple, is fit to the manufacturing of mechanization flowing water, but this kind folder is when using bolt locking folder, and the folder bending resistance is reported to the leadship after accomplishing a task, and the thickness of the bending steel plate that must thicken in design causes folder weight to increase.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of core clamping bending resistance loss of weight structure simple in structure, ingenious, rational is provided, and this lightweight construction, bending strength height are fit to the mechanization large-scale production; and good looking appearance, technology is simple.
The technical scheme that provides according to the utility model: a kind of core clamping bending resistance loss of weight structure, it is characterized in that: the folder body comprises the boatswain chair that rises perpendicular to the folder base, play the boatswain chair both sides and have symmetrically arranged upper hem, and playing the boatswain chair both sides is provided with for lifting lifting eye unshakable in one's determination, offer the core through screw rod hole in the boundary central authorities of playing boatswain chair and upper hem, offer other screw hole at folder body two ends.
As further improvement of the utility model, described upper hem is parallel to the folder base.
As further improvement of the utility model, the width of described upper hem is less than the width on folder base.
As further improvement of the utility model, described folder base is provided with bayonet socket.
As further improvement of the utility model, each end of described folder body offers two other screw holes of arranging up and down.
The utility model compared with prior art, advantage is: on the basis of identical weight folder, folder intensity is protected (1), and bending resistance is strong; (2) the folder production technology is simple and clear, abandons weldment, is applicable to equipment processing, is difficult for taking place artificial dimensional error, the easier volume production scale that reaches; (3) profile is more attractive in appearance.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is vertical view of the present utility model.
Fig. 3 is upward view of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
Shown in Fig. 1 ~ 3, comprise upper hem 1, play boatswain chair 2, other screw hole 3, core through screw rod hole 4, folder body 5, folder base 6, bayonet socket 7, lifting eye 8 etc.
Shown in Fig. 1 ~ 3, the utility model is a kind of core clamping bending resistance loss of weight structure, folder body 5 comprises the boatswain chair 2 perpendicular to folder base 6, play boatswain chair 2 both sides and have symmetrically arranged upper hem 1, and playing boatswain chair 2 both sides is provided with for lifting lifting eye 8 unshakable in one's determination, play boatswain chair 2 surfaces and can be applicable to installation product nameplate and all kinds of terminal box simultaneously, offer core through screw rod hole 4 in the boundary central authorities of playing boatswain chair 2 and upper hem 1, be used for installing core through screw rod, offer other screw hole 3 at folder body 5 two ends, be used for installing other screw rod.
Described upper hem 1 is parallel to folder base 6.
The width of described upper hem 1 is less than the width on folder base 6.
Described folder base 6 is provided with bayonet socket 7.
Described folder body 5 each end offer two other screw holes of arranging up and down 3.
This folder structure and existing folder structure all are to finish fastening function to iron core by screw rod pressurization, and the colleague is as the part of skeleton function unshakable in one's determination, the position that provides for the installation of transformer parts.
The utility model is by after the cutting of full wafer steel plate process, carries out processing after the bilateral bending.Core clamping adopts two to be one group in application in practice, in opposite directions and the mounting means of dress, and by core through screw rod and the fastening clamping of other screw rod yoke sheet unshakable in one's determination, plays fastening effect.Because when fastening, the folder moment of flexure usually occurs between other screw rod and the serial screw rod, designs two-fold limit structure here and plays the bending resistance effect, folder is installed accessory unshakable in one's determination and has been focused on the boatswain chair, the folder global design, and outward appearance and assembly technology have all obtained optimization.
