CN103295734A - Flameproof end cover - Google Patents

Abstract

The invention discloses a flameproof end cover which comprises a square flange (1), a wiring cavity (2), a lifting lug (3), a spigot type end flange (4), an end cover plate (5) and a reinforcing plate (6). The flameproof end cover is characterized in that the spigot type end flange (4) is arranged at the peripheral edge of the end cover plate (5), the wiring cavity (2) is connected onto a panel of the end cover plate (5), the square flange (1) is connected onto the wiring cavity (2), the reinforcing plate (6) is positioned on one side of the wiring cavity (2) and connected with the end cover plate (5), and the lifting lug (3) is positioned on the other side of the wiring cavity (2) and connected with the end cover plate (5). The flameproof end cover has the advantages of short production cycle, high mechanical strength and higher flameproof performance.

Description

A kind of explosion insulation shell

Technical field

The present invention relates to the transformer shell system and make fields of measurement, particularly a kind of novel quick location drill jig in transformer high-low pressure end cap machining frock field.

Background technology

At present the round flange on the transformer high-low pressure end cap adopts manually to put earlier from pallet when boring mostly, dash with sample again and strike the sample dotting punch, Zuan Kong mode at last, this mode complicated operation, production cycle are long, versatility a little less than, unstable product quality.

Summary of the invention

Goal of the invention: in order to overcome the defective of above-mentioned prior art, provide a kind of round flange to locate drill jig fast.

Technical scheme: a kind of explosion insulation shell, comprise square flange (1), wire connection cavity (2), hanger (3), seam type end flanges (4), end casing (5), stiffener (6), the circumferential edges of described end casing (5) is provided with seam type end flanges (4), connect wire connection cavity (2) on described end casing (5) panel, described wire connection cavity (2) is gone up connection side's flange (1), described stiffener (6) is positioned at a side of wire connection cavity (2), and be connected with end casing (5), described hanger (3) is positioned at the opposite side of wire connection cavity (2), and is connected with end casing (5).

The present invention adopts technique scheme, has following beneficial effect: this invention has advantage with short production cycle, that mechanical strength is high, explosion insulation performance is higher.

Description of drawings

Fig. 1 is the front view of one embodiment of the invention;

Fig. 2 is that embodiment of the invention Fig. 1 is along the cutaway view of A-A direction, among the figure 1, square flange; 2, wire connection cavity; 3, hanger; 4, seam type end flanges; 5, end casing; 6, strengthen version.

Embodiment

Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.

As shown in Figure 1, a kind of explosion insulation shell, comprise square flange 1, wire connection cavity 2, hanger 3, seam type end flanges 4, end casing 5, stiffener 6, the circumferential edges of end casing 5 is provided with seam type end flanges 4, connects wire connection cavity 2, connection side's flange 1 on the wire connection cavity 2 on end casing 5 panels, stiffener 6 is positioned at a side of wire connection cavity 2, and be connected with end casing 5, hanger 3 is positioned at the opposite side of wire connection cavity 2, and is connected with end casing 5.

The method of work of this kind device is: only need an operator will weld the end cap of getting well winch to fix on the vertical lathe after, time processing goes out seam type explosion suppresion surface, can reach when using novel explosion insulation shell with the assembling of end circle and can utilize the seam location, reduce installation time, and improved the purpose of housing mechanical strength.

The implementation method of this kind embodiment is that this explosion insulation shell is Welding Structure, gets the blank that needs welding earlier ready, to be welded intact after, after handling through oscillating aging, shot-peening, primer spray again, after treating that priming paint parches, winch on the vertical lathe and fastening, last car goes out seam type explosion suppresion surface.

Claims (1)

1. explosion insulation shell, comprise square flange (1), wire connection cavity (2), hanger (3), seam type end flanges (4), end casing (5), stiffener (6), it is characterized in that, the circumferential edges of described end casing (5) is provided with seam type end flanges (4), connect wire connection cavity (2) on described end casing (5) panel, described wire connection cavity (2) is gone up connection side's flange (1), described stiffener (6) is positioned at a side of wire connection cavity (2), and be connected with end casing (5), described hanger (3) is positioned at the opposite side of wire connection cavity (2), and is connected with end casing (5).
