Abstract
The utility model provides an internally tensioning clamp for an insulator, wherein a lead screw-like mandrel is connected on a frame; a tapered slipper block is fixed on the mandrel; and a pair of tensioning devices having the same structure is respectively fixed at two ends of the frame. Besides, the end section of a push rod of the tensioning device is set in a triangular shape. The structure has the following advantages: the push rod with the triangular section of the tensioning device is matched with the tapered slipper block, and the internal tension of the insulator can be fastened by means of the pressing of the two end surfaces; and the internally tensioning clamp has simple structure and easy operation.
Description
Technical field
The utility model relates to stress accommodation in a kind of insulator, is specifically related to open clamping device in a kind of insulator that makes things convenient for the insulator end face to handle.
Background technology
Because insulator is circular, be difficult for fixing, the insulator end face of prior art all is firmly fastening in exterior insulator when handling, this shortcoming is: surface treatment is during to the fixing position of external force, fixture will be unloaded, retighten at other positions, an insulator will be fixed repeatedly and end face could be disposed.
The utility model content
Main task of the present utility model is to provide stress accommodation in a kind of insulator, is specifically related to open clamping device in a kind of insulator that makes things convenient for the insulator end face to handle.
In order to solve above technical problem, stress accommodation in a kind of insulator of the present utility model connects axle by the center of frame and constitutes, and it is characterized in that: the two ends up and down of described frame are bolted to connection a pair of motion device; Be fixed with conical sliding block by the Hough piece with hexagon socket head cap screw on the described axle.
Further, described tensioning apparatus is by overlapping nylon sheet, location-plate, spring successively on the screw, and further, fixedly connected push rod constitutes at its top.
Further, the end cross-sectional of described push rod is a triangle.
Further, described axle is the screw mandrel shape.
Further, described conical sliding block is connected with the key that is connected between the axle.
The advantage of above structure is: adopting the tensioning apparatus cross section is that leg-of-mutton push rod and conical sliding block match, and by the extruding of both ends of the surface, realizes that the internal tension of insulator is fastening, simple in structure, easy to operate.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
As shown in the figure, pass through the shaft-like axle 3 of key 2 connecting filaments, on axle 3, pass through fixedly conical sliding block 7 of Hough piece 4 usefulness screws 5 and nut 6 in the center of frame 1.
The identical tensioning apparatus of a pair of structure are fixed by bolt 8,9 respectively in two ends in frame 1.Connecting tensioning apparatus with one of them below is example, and carry out the description of structure: described tensioning apparatus is made of screw 10, nylon sheet 11, location-plate 12, spring 13, push rod 14; Fixedly connected with bolt 8 in the end of location-plate 12; The bottom of screw 10 is with nylon sheet 11, and screw 10 is screwed on the location-plate 12, and is with spring 13 above location-plate 12, and it is leg-of-mutton push rod 14 that its top is fixedly connected with end cross-sectional.
During work, insulator is enclosed within this on the tensioning apparatus, and nylon sheet contacts with its inwall; The axle 3 of rotary screw rod shape drives conical sliding block 7 and travels forward then, and its end face is against on the leg-of-mutton push rod 14, realizes the interior tensioning of insulator, has made things convenient for the end face of insulator to handle.
