Abstract
The utility model relates to an accessory special for a nuclear power bridge, and belongs to the technical field of low-voltage power transmission and distribution equipment accessories. The accessory special for the nuclear power bridge comprises a fixing clamp, a spring nut, and a bolt, wherein the width of the lower panel of the fixing clamp is matched with the width of a rabbet of C-shaped steel used for fixing the cable bridge, grooves which are matched with two edgefolds of the C-shaped steel are formed in the upper panel of the spring nut, a spring is arranged on the lower panel of the nut, and the bolt passes through the fixing clamp and is connected with the spring nut. When the accessory is installed, one end of the fixing clamp is pressed on a side plate of the cable bridge, the lower panel of the other end of the fixing clamp is clamped in the rabbet of the C-shaped steel which fixes the cable bridge, so that the fixing clamp is prevented from rotating. After the spring nut is placed in the C-shaped steel, the grooves in the upper panel of the nut are matched with the edgefolds of the C-shaped steel, so that the spring nut is prevented from sliding and rotating in the C-shaped steel. At the same time, the spring nut is under the spring force, so that the bolt can be installed without being held by hands. The efficiency of field installation, the shockproof performance of the cable bridge, and installation soundness is greatly improved.
Description
Technical field
The utility model belongs to low pressure equipment for power transmission and distribution attachment technique field, relates in particular to the special accessories that a kind of nuclear power is used cable testing bridge.
Background technique
Cable testing bridge is to consist of the rigid construction system with intensive carrying cable by the straightway of pallet or ladder, curved logical, assembly and trailing arm, suspension bracket etc., be the staple product that electric power transfer is responsible in low pressure power transmission and distribution field, extensively be used at building and industrial and mineral, factories and miness place.Particularly the cable testing bridge of nuclear island of nuclear power station part has begun to adopt production domesticization in recent years, but very strict to the requirement of quality of product, shockproof requirements is higher; The soundness of installing between cable testing bridge and the trailing arm is the key factor of anti-seismic performance when affecting the operation of cable testing bridge equipment.The normal cable crane span structure adopts common pressing plate, fastening piece to fix when mounted, and firmly coefficient is low, can't satisfy the technical requirements that nuclear power station is installed cable testing bridge at all.
The model utility content
For above-mentioned technical problem, the utility model provides the nuclear power crane span structure special accessories that a kind of anti-seismic performance is good, connection is firm.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of nuclear power crane span structure special accessories comprises fixing clamp, spring nut and bolt, and the C shaped steel width of rebate of described fixing clamp lower plane width and attached cable crane span structure is supporting; The upper plane of spring nut with the supporting groove of two flangings of described C shaped steel, the nut lower plane is with spring, described bolt passes fixing clamp and is connected with described spring nut.
When mounted, fixing clamp one side pressure is on the side plate of cable testing bridge, the lower plane of the other end is stuck in the C shaped steel notch of attached cable crane span structure, prevent the rotation of fixing clamp, after spring nut is put into C shaped steel, the notch on plane and C shaped steel flanging are supporting on the nut, prevented that spring nut from sliding and rotate in C shaped steel, spring nut is under the effect of spring power simultaneously, need not just to live with hand rest can construction bolt again, improves greatly field erected efficient, cable testing bridge shockproof properties and installation soundness.
Description of drawings
Fig. 1 is that the utility model nuclear power crane span structure special accessories is connected to the mounting structure schematic diagram on the cable testing bridge;
Fig. 2 is that the utility model nuclear power crane span structure special accessories is connected to the enlarged view on the cable testing bridge;
Fig. 3 is A among Fig. 2-A sectional view.
Embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
As shown in the figure, the utility model nuclear power crane span structure special accessories comprises 7 font fixing clamps 3, spring nut 7 and bolt 4, and C shaped steel 1 width of rebate of described fixing clamp 3 lower planes, 6 width and attached cable crane span structure is supporting; The upper plane of spring nut 7 with the supporting groove of two flangings of described C shaped steel, the nut lower plane is with spring 8, described bolt 4 passes fixing clamp 3 and is connected with described spring nut 7.
When mounted, fixing clamp one end 5 is pressed on the side plate of cable testing bridge 2, the lower plane of the other end is stuck in C shaped steel 2 notches of attached cable crane span structure, prevent the rotation of fixing clamp 3, after spring nut 7 is put into C shaped steel 1, the notch on plane and C shaped steel flanging are supporting on the nut, prevented that spring nut 7 is in 1 interior slip and the rotation of C shaped steel, spring nut 7 is under the effect of spring 8 elastic forces simultaneously, need not just to live with hand rest can construction bolt 4 again, improves greatly field erected efficient, cable testing bridge shockproof properties and installation soundness.
The utility model nuclear power crane span structure special accessories has boundary dimension little, easy to use, reliable, and advantage attractive in appearance is installed, and closely supporting by fixing clamp and spring nut and C shaped steel strengthened the field erected soundness of cable testing bridge.
Above embodiment's description is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
