Abstract

The utility relates to a mining transformer, namely flame-proof type dry type transformer iron core clamping device for mining. The transformer comprises a superposed iron yoke. The superposed iron yoke is provided with clamping beam at upper and lower part; the clamping beam is provided with flat support plate at two sides; the flat support plate is articulated with U-shaped bolt locked by nut; weftless glass fiber tape is connected between upper and lower U-shaped bolt of superposed iron yoke. The transformer has merits of reasonable structure, convenient machining and regulation, proper force to iron core, good clamping effect.

Description

The flameproof dry type transformer Iron Core Clamping Device

Technical field

The utility model relates to a kind of mining transformer, i.e. the flameproof dry type transformer Iron Core Clamping Device.

Background technology

In prior art, the flameproof dry type transformer Iron Core Clamping Device comprises transformer stack iron yoke, and there is the clamping crossbeam of channel-section steel shape stack iron yoke above and below.Referring to Fig. 1, there is the flat support plate of inclined weld both sides in the clamping crossbeam of channel-section steel shape, are mounted with the tilting U type screw rod that connects by nut locking on the flat support plate, are welded with corrosion resistant plate between the U type screw rod on the above and below.Its shortcoming is that tilting U type screw-rod structure is unreasonable, and the clamping force of generation is little, and influence is unshakable in one's determination to be clamped, easy generation noise in actual uses of transformer, and the welding of corrosion resistant plate needs the special welding instrument; To on channel-section steel, process inclined hole, the processing time consuming effort.

The utility model content

The purpose of this utility model is to provide a kind of rational in infrastructure, the flameproof dry type transformer Iron Core Clamping Device that result of use is good at above-mentioned deficiency.

Technical solution of the present utility model is: the flameproof dry type transformer Iron Core Clamping Device comprises transformer stack iron yoke, and there is the clamping crossbeam stack iron yoke above and below.Clamping the crossbeam both sides has flat support plate, is mounted with the U type screw rod that connects by nut locking on the flat support plate, connects between the U type screw rod on the stack iron yoke above and below and has or not the latitude glass tape.

The utility model has the advantages that: rational in infrastructure, processing, easy to adjust unshakable in one's determination stressedly rationally clamps effectively, and loss is low, and noise is little in the use.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment

Referring to Fig. 2,3,4, the flameproof dry type transformer Iron Core Clamping Device comprises transformer stack iron yoke 1, and there is the crossbeam 2 of clamping stack iron yoke 1 above and below.Clamping crossbeam 2 both sides has flat support plate 3, is mounted with the U type screw rod 4 that connects by nut locking on the flat support plate 3, connects between the U type screw rod 4 on stack iron yoke 1 above and below and has or not latitude glass tape 5.

The clamping crossbeam 2 of stack iron yoke 1 on every be twice, spaced two groups of U type screw rod 4 assemblies on each clamping crossbeam 2.

Claims

1. flameproof dry type transformer Iron Core Clamping Device, comprise transformer stack iron yoke (1), there is clamping crossbeam (2) stack iron yoke (1) above and below, it is characterized in that clamping crossbeam (2) both sides flat support plate (3) is arranged, be mounted with the U type screw rod (4) that connects by nut locking on the flat support plate (3), connect between the U type screw rod (4) on stack iron yoke (1) above and below and have or not latitude glass tape (5).

2. according to the described flameproof dry type transformer Iron Core Clamping Device of claim 1, the clamping crossbeam (2) on every of the iron yoke (1) of it is characterized in that superposeing is twice, and each clamps crossbeam (2) last spaced two groups of U type screw rods (4) assembly.
