A kind of totally-enclosed cable testing bridge
Technical field
The utility model relates to the field of sealing technology of cable testing bridge, particularly the totally-enclosed cable testing bridge of one.
Background technology
Closed wire casing popular in the market, usual wire casing body is that three side sealing closes structure, add slot cover plate in addition, connected mode wherein between wire casing is connecting plate, wire casing body needs reserved screw hole connect for connecting plate, the mode that slot cover plate is installed is generally self-tapping screw tightening formula or is buckle, cover buckle formula, there is following problem: 1, owing to adopting the form of connecting plate to connect, seam crossing inherently enters dust, and dust is difficult to clean out after entering crane span structure; 2, popular on market closed wire casing bridge cover plate is buckle-type, cover plate junction cannot reach completely airtight, because the error of construction or the error of cover plate itself inherently have gap to cause entering dust, but in food factory, in the food enterprise of especially foreign capitals, GMP requires to require higher for electric equipment hygienic design in enterprise, easy laying dust place necessarily needs to avoid, and technical problem to be solved by this invention is and uses a kind of fully closed cable testing bridge in food car.
Summary of the invention
For existing closed wire casing because the mounting means of wire casing junction and slot cover plate cannot to meet in food factory the requirement of not laying dust in crane span structure, the utility model provides a kind of totally-enclosed cable testing bridge, in order to achieve the above object, the utility model by the following technical solutions: the utility model comprises crane span structure body 1, flange frame 3, bridge cover plate 2, be bridge cover plate 2 above described crane span structure body 1, described crane span structure body 1 front and back sides is flange frame 3, described crane span structure body 1 is Qian type structure, comprise left facade and right facade two facade parts and a lower plane, the upper surface of the left facade of described crane span structure body 1 arranges a vertical flange 11 to the right, described crane span structure body 1 right facade upper surface arranges a vertical flange 12 to the left, the outer surface of the right facade of described crane span structure body 1 is provided with hasp lock 42, described bridge cover plate 2 lower surface is positioned at the upper surface of crane span structure body 1 flange, described bridge cover plate 2 left and right sides are also respectively arranged with flange 22 vertically downward, hinge 21 is provided with on the left of described bridge cover plate 2 upper surface, the right both sides of described bridge cover plate 2 upper surface are provided with the hasp 41 matched with hasp lock 42.
Preferably, the flange width of described crane span structure body about 1 facade is not more than the width of left and right facade or the width of crane span structure body 1, and the flange upper surface of described crane span structure body about 1 facade is also provided with rubber blanket.
Preferably, described flange frame 3 is square frame, flange frame 3 length be not less than the length of crane span structure body 1 lower plane, the width of described flange frame 3 is not less than the height of crane span structure body about 1 facade, and described flange frame 3 is drilled with circular hole 31.
The beneficial effects of the utility model: the turnup structure of the utility model bridge cover plate and crane span structure body, and the rubber gasket structure that crane span structure body flange upper surface is arranged, there is good sealing and dustproof effect, adopt the type of attachment of hasp and hinge, clean after being convenient to laying dust.

Embodiment
As shown in Figure 1, the utility model comprises crane span structure body 1, flange frame 3, bridge cover plate 2; Described crane span structure body 1 is Qian type structure, comprise left facade and right facade two facade parts and a lower plane, the upper surface of the left facade of described crane span structure body 1 arranges a vertical flange 11 to the right, described right facade upper surface arranges a vertical flange 12 to the left, as shown in Figure 2, the width of the flange 11 of described crane span structure body about 1 facade is not more than the width of left and right facade or the width of crane span structure body 1, four breach are formed, for meeting the installation requirements of flange frame 3 with flange 11 place at crane span structure body 1.
Be bridge cover plate 2 above described crane span structure body 1, described bridge cover plate 2 lower surface is positioned at the upper surface of crane span structure body 1 flange, described bridge cover plate 2 left and right sides are also respectively arranged with flange 22 vertically downward, the distance of two flange 22 in left and right of bridge cover plate 2 is greater than the distance of two flange 11 on crane span structure body 1, when bridge cover plate 2 is connected with crane span structure body 1, two, the left and right flange 22 of bridge cover plate 2 is positioned at outside the outer surface of crane span structure body about 1 two facade, junction reaches good sealing and dustproof effect, and bridge cover plate 2 can paste sealing strip or crane span structure body 1 flange upper surface in flange edges and corners arranges rubber blanket, to reach bridge cover plate 2 and crane span structure body 1 better sealing effectiveness, the described bridge cover plate 2 upper surface left and right sides is respectively arranged with hinge 21, hasp 41, hinge 21 other end connects the outer surface of the left facade of crane span structure body 1, hasp 41 is corresponding with the hasp lock 42 of the outer surface of the right facade of crane span structure body 1, crane span structure body 1 and bridge cover plate 2 is made to reach flexible connection, clean after being convenient to laying dust.
The front and back sides of described crane span structure body 1 is flange frame 3, described flange frame 3 is square frame, flange frame 3 length be not less than the length of crane span structure body 1 lower plane, the width of described flange frame 3 is not less than the height of crane span structure body about 1 facade, described flange frame 3 is drilled with circular hole 31, flange frame is fixed on the front and back sides of crane span structure body 1 by circular hole, and rubber sheet gasket can also be placed to reach better obturation effect in flange frame 3 and crane span structure body junction.
