Abstract
A guide track mechanism in a shielded metal enclosed type switch equipment is provided, which is used for supporting a handcart in a heavy-current circuit breaker (no more than 1600A). Three cross sections are welded by three L-shaped angle block bars towards the same direction, two of which are staggered up and down. All bending edges are spaced at intervals. The third angle block bar is welded on a bending edge of a lower angle block bar with a back-to-back layout and shares the same bottom surface. A cross section is bended to realize back-to-back connection similar to two L-shaped angle block bars. One bottom edge of the angle block bar with two staggered bottom surfaces is connected with the bottom surface of the third angle block bar and a lower angle block bar. The angle block bar is made from stainless steel plate and welded through argon-arc welding. Due to laminated welding of the angle block angle, the guide track is provided with an enhanced strength, higher deformation resistance, simple technical flows and stronger safety and reliability in terms of operating performance.
Description
Technical field
The utility model relates to a kind of guide rail mechanism, especially relates in a kind of armored metal enclosed switchgear, supports the guide rail structure of the mid-handcart of big electric current (1600A≤) circuit breaker.
Background technology
At present, armored metal enclosed switchgear both domestic and external, all there are shortcomings such as insufficient strength, easy deformation in the guide rail that supports the mid-handcart of big electric current (1600A≤) circuit breaker, and there is potential safety hazard in use, directly product and personal safety is constituted a threat to.
The utility model content
The purpose of this utility model, be to provide a kind of intensity height, rational in infrastructure, cost is low, can satisfy the guide rail structure of the armored metal enclosed switchgear of function of use.
The technical scheme that its technical problem that solves the utility model adopts is: guide rail is that three sliver transvers sections are L shaped bent plate bar with towards welding, and two with the stack of upper and lower formula, and each bending edge has at interval; The 3rd bent plate bar be welded on down on the bending edge of bent plate bar with form back-to-back and the bottom surface concordant; One cross section o ing is as two L shaped bent plate bars that the bent plate bar sticks together back-to-back, stagger in two bottom surfaces, be welded on aforesaid the 3rd bent plate bar and the bottom surface of bent plate bar down to be adjacent to above the base.
Describedly be welded as the argon arc plug welding.
Described guide material is a corrosion resistant plate, and double bending connects therebetween and adopts the argon arc welding welding, and sets up two fixing points that connect with framework.
The beneficial effects of the utility model are: because guide rail adopts the stack of bent plate bar to be welded, intensity do not increase, yielding and simplified technological process, can satisfy function of use and more safe and reliable.
Description of drawings
In conjunction with the accompanying drawings and embodiments the utility model is further specified.
Fig. 1 looks schematic diagram for the master of the utility model guide rail embodiment.
Fig. 2 is the sectional drawing of guide rail.
Among the figure: go up bent plate bar 1, following bent plate bar 2, backrest bent plate bar 3, two-fold bent plate bar 4, argon arc plug weld 5.
Embodiment
Can see from Fig. 1 and Fig. 2, the guide rail of the utility model embodiment is a L shaped bent plate bar 1,2,3 with towards welding with three sliver transvers sections, and promptly bending edge all bends towards a direction, and wherein bent plate bar 1 is superimposed upon on the bent plate bar 2, each bending edge has at interval, bent plate bar 1,2, the stack edge concordant; The bending edge of bent plate bar 3 is welded on the bending edge of bent plate bar 2 with form back-to-back, the bottom surface on the bending edge upper edge of two bent plate bars and stack limit is concordant; Other has a cross section o ing as the two L shaped bent plate bars 4 that bent plate bar bending edge sticks together back-to-back, stagger in two bottom surfaces, and it is to be attached to the bottom surface of aforesaid bent plate bar 2 and bent plate bar 3 above the base; On each bent plate bar, have the plug welding hole, be welded into integral body with argon arc welding.
The bent plate material is a corrosion resistant plate, and sets up two fixing points that connect with framework.
Because each bent plate bar curves the right angle and stack is welded, intensity increases greatly can satisfy instructions for use.
Can be screwed during installation on preceding crimp that is installed in the left side plate of cabinet before the switch cubicle and the support that contact box is installed, be connected with the preceding cabinet left side plate of switch cubicle with bolt.
Claims (2)
1, a kind of guide rail structure of armored metal enclosed switchgear is characterized in that: described guide rail is: three sliver transvers sections are L shaped bent plate bar with towards welding, and two with the stack of upper and lower formula, and each bending edge has at interval; The 3rd bent plate bar be welded on down on the bending edge of bent plate bar with form back-to-back and the bottom surface concordant; One cross section o ing sticks together back-to-back as two L shaped bent plate bars, and the bent plate bar that staggers in two bottom surfaces, it to be to be attached to the bottom surface of aforesaid the 3rd bent plate bar and following bent plate bar above the base.
2, the guide rail structure of armored metal enclosed switchgear according to claim 1 is characterized in that: described bent plate material is corrosion resistant plate, has the plug welding hole on each bent plate bar, is welded into integral body with argon arc welding.
