Abstract
The invention relates to a special accessory for a nuclear power bridge frame and belongs to the technical field of accessories of low-voltage power transmission and distribution equipment. The special accessory for the nuclear power bridge frame comprises a fixed clip, a spring nut and a bolt, wherein the width of the lower plane of the fixed clip is matched with that of a notch of C-shaped steel for fixing a cable bridge frame; a groove matched with two folding edges of the C-shaped steel is formed on the upper plane of the spring nut; a spring is arranged on the lower plane of the nut; and the bolt passes through the fixed clip and is connected with the spring nut. During mounting, one end of the fixed clip is pressed on a side plate of the cable bridge frame and the lower plane at the other end of the fixed clip is clamped in the notch of the C-shaped steel for fixing the cable bridge frame, so that rotation of the fixed clip is avoided; after the spring nut is placed into the C-shaped steel, the notch of the upper plane of the nut is matched with the folding edges of the C-shaped steel, so that the spring nut is prevented from sliding and rotating in the C-shaped steel; and under the action of the elastic force of the spring of the spring nut, the bolt can be mounted without being supported by hands, so that the field mounting efficiency and the earthquake resistance and the mounting fastness of the cable bridge frame are greatly improved.
Description
Technical field
The invention belongs to low pressure equipment for power transmission and distribution attachment technique field, relate 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.
Summary of the invention
For above-mentioned technical problem, the invention 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 used in the present invention 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.

Fig. 1 is that nuclear power crane span structure special accessories of the present invention is connected to the mounting structure schematic representation on the cable testing bridge;
Fig. 2 is that nuclear power crane span structure special accessories of the present invention 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 present invention is made and to further specify.
As shown in the figure, nuclear power crane span structure special accessories of the present invention 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.
Nuclear power crane span structure special accessories of the present invention 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 inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
