Detailed Description
The invention will be further described with reference to the drawings and specific examples.
As shown in fig. 1 to 5: the main body 13 is in a side-standing concave structure or a side-standing channel steel structure and is made of insulating materials; the front face of which is provided with a plurality of sliding grooves 15. The main body 13 is provided with a parallel groove clamp positioning frame and a positioning device, and a lifting device is arranged below the main body 13. Wherein:
the parallel groove clamp positioning frame is composed of a lifting plate 8 positioned in a main body 13, spring clamps 3 respectively pivoted on two sides of the lifting plate, a pressing plate 4 arranged on the front surface of the lifting plate 8 through an elastic device and a sleeve mounting plate 10 fixedly connected with the lifting plate 8, wherein a plurality of sleeves 11 are fixed on the sleeve mounting plate, and each sleeve 11 extends out of the back surface of the main body 13 through a corresponding sliding groove 15. The spring clamp 3 is composed of two clamp bodies (not shown) pivoted on the lifting plate 8 through a pin shaft (not shown) and a torsion spring 9 for pressing the jaws of the two clamp bodies, and the function of the spring clamp 3 is to fix the lead wire of the new equipment in the parallel groove clamp so as to prevent the lead wire from slipping. The positioning device consists of two wire hanging positioning blocks 1 fixed on the top of a main body 13 and a plurality of positioning blocks 2 which are respectively positioned on two sides of each sleeve 11 and fixed on the front surface of a sleeve frame 10. The lifting device consists of a connecting sleeve 18 fixed at the bottom of the main body 13 through a flange plate 14, an insulating sleeve 6 movably connected with the connecting sleeve through a connecting device, a nut 17 fixed in the insulating sleeve, and a screw rod 7 matched with the nut and penetrating through the main body 13 upwards to be contacted with the lifting plate 8.
The lifting plate 8 is of a hollow structure, the elastic device is composed of a telescopic rod 5, compression springs 19 and adjusting nuts 20, the two ends of the telescopic rod extend into the lifting plate 8, the middle section of the telescopic rod is bent into an L-shaped space structure, the compression springs 19 are respectively arranged at the two ends of the telescopic rod, the adjusting nuts 20 are respectively fixed at the two ends of the telescopic rod and compress the springs 19 in the lifting plate 8, and the middle section of the telescopic rod 5 penetrates through the pressing plate 4 to compress the telescopic rod on the front surface of the lifting plate 8.
The connecting device consists of a plurality of balls 22 arranged on the wall of the insulating tube 6, a jacket 16 arranged on the surface of the insulating tube 6 through clamp springs and a spring 21 arranged between the jacket and the insulating tube 6, wherein a ring groove (not shown in the figure) matched with the balls 22 is formed on the surface of the connecting sleeve 18, and the jacket 16 presses the balls 22 in the ring groove.
In order to enable accurate positioning of the parallel groove clamp, the lifter plate 8 is mounted in the main body 13 by means of two guide posts 12.
When the parallel groove clamp (not shown) is tightly propped against the sleeve mounting plate 10 through the pressing plate 4, a locking screw (not shown) and a nut (not shown) of the parallel groove clamp are concentric and sleeved with a ratchet socket wrench (not shown) arranged in the sleeve 11, a pre-connection wire (not shown) is clamped and stably kept in a lower groove (not shown) of the parallel groove clamp through the spring clamp 3, the lifting plate 8 can be pushed to move upwards along the guide post 12 through the screw rod 7 by utilizing the insulating rod (not shown) to rotate the edge sleeve 6 until a charged wire (not shown) enters an upper groove (not shown) of the parallel groove clamp, and at the moment, the tool is kept stable; the ratchet socket wrench is operated by another insulating rod (not shown in the figure) to fasten the screw and the nut of the parallel groove clamp. The lifting plate 8 can be driven to descend by the screw rod 7 by reversely rotating the edge sleeve 6 until the spring clamp 3 is separated from the lead, so that the tool release is realized.
