In the existing live-line drainage line connecting operation process, a parallel groove clamp is required to be used, and the drainage line can be connected and fixed on a main guide line to realize power connection and point taking.
The existing parallel groove clamp is generally provided with two wire grooves, and a plurality of parallel bolts are required to be rotated one by one to be compressed and fixed, so that the time of high-altitude live working is prolonged, and the risk of working is increased. In particular, in the insulating rod operation method, at least two insulating rods are required to operate (one is used for temporary fixing or wire lapping, and the other is used for screwing and fixing), on one hand, an operator can hardly control the direction and the position of the wire lapping clamp on the rods, on the other hand, the labor intensity of the operator is increased, and operation fatigue is caused. Therefore, the parallel groove clamp capable of conveniently and quickly realizing wiring drainage is needed at present, the high-altitude live working time and the working strength of operators are reduced, and the operation difficulty is reduced.

The sliding buckle 303 is a bar-shaped structure, two ends of which are semicircular, and an adapting groove 303a is formed inside. The invention sets the following steps: the vertical distance between the second guiding section 302a and the surface of the first guiding section 301a is less than the length of the sliding buckle 303, and the vertical distance between the third guiding section 302b and the surface of the first guiding section 301a is greater than or equal to the length of the sliding buckle 303; the vertical distance between the third guide section 302b and the outer end face of the blocking projection 301b is greater than or equal to the width of the sliding buckle 303.
One end of the pulling member 304 is slidably connected in the fitting groove 303a, and the other end is hinged to the inner end of the adjusting screw 305. As shown in fig. 4(a), the present invention sets: in the initial state, the sliding buckle 303 is located between the second guiding section 302a and the first guiding section 301a, the fitting groove 303a on the sliding buckle 303 is closer to the second guiding section 302a, and the sliding buckle 303 has a tendency to gradually move away from the third frame 102c from the first guiding section 301a to the second guiding section 302 a.
Preferably, the pulling member 304 includes a pulling frame 304a inserted into the fitting groove 303a and a hinge base 304b fixed to an outer end edge of the pulling frame 304 a. The inner end of the adjusting screw 305 is hinged to the hinge base 304b of the pulling member 304. In order to prevent the structure conflict between the limiting protrusion 302d and the adjusting screw 305, an avoiding slot hole 302d-1 matched with the outer diameter of the adjusting screw 305 is arranged on the limiting protrusion 302 d.

Preferably, the two side edges of the inner side surfaces of the first sliding part 301 and the second sliding part 302 are provided with limit edges B capable of being clamped at the two sides of the sliding buckle 303, and the sliding buckle 303 can slide in an interlayer formed by the limit edges B at the two sides, so that the sliding buckle 303 is prevented from falling.
The using method of the invention comprises the following steps:
the drainage wire is placed on the first bottom plate 101b and the main drainage wire is placed on the second bottom plate 101c, and then the adjusting screw 305 is rotated to pull the sliding buckle 303 outward by the pulling member 304.
Because the present invention defines that "in the initial state, the sliding buckle 303 is located between the second guiding section 302a and the first guiding section 301a, the adapting groove 303a on the sliding buckle 303 is closer to the second guiding section 302a, and the sliding buckle 303 has a trend of gradually departing from the third frame 102c from the first guiding section 301a to the second guiding section 302 a", as shown in fig. 4(a) -4 (b), the sliding buckle 303 can drive the first sliding member 301 to integrally slide outwards together under the limiting and guiding effects of the second guiding section 302a, and the first sliding member 301 can drive the first squeezing rods 201a-1 to rotate through the first connecting rod 201b, so as to realize the squeezing process of the drainage wire by the squeezing heads T of the first squeezing rods 201 a-1.
As shown in fig. 4(b), when the sliding buckle 303 slides outward to the transition broken surface 302c, since the distance is increased, the third guiding section 302b no longer plays a role in limiting and guiding the sliding buckle 303, so that the pulling element 304 at this time can pull the sliding buckle 303 to turn over itself and gradually turn over to contact and attach to the outer slope of the elastic cushion 301d, as shown in fig. 4(c), and meanwhile, the pulling frame 304a can slide along the adapting groove 303a, so that the sliding buckle 303 can continue to turn over and finally be pulled into the interlayer formed by the third guiding section 302b and the blocking protrusion 301b, as shown in fig. 4 (d). If the adjusting screw 305 is continuously rotated, as shown in fig. 4(d) -4 (e), the sliding buckle 303 can pull the second sliding member 302 to slide outward by pulling the limiting protrusion 302d, and the second sliding member 302 can drive each second extrusion rod 202a-1 to rotate by the second connecting rod 202b, so as to realize the extrusion process of the pressing head T of each second extrusion rod 202a-1 to the main guide wire.
From the above-described stroke variation: the invention can realize the extrusion process of the drainage wire and the main guide wire in sequence only by rotating the adjusting screw 305 outwards without repeated point-to-point rotation and other auxiliary operations, thereby ensuring the simple and rapid fire-building process and ensuring the safety.
It should be noted that: because the outer diameter of the main guide wire is thicker than that of the drainage wire, in order to ensure that the driving assembly 300 can pull and press the main guide wire and the drainage wire, the invention needs to ensure that the stretching length of the driving assembly 300 to the first connecting rod 201b is longer than that of the second connecting rod 202b (the first extrusion rod 201a-1 needs to be rotated by a larger angle than that of the second extrusion rod 202a-1 to press the drainage wire), that is: the drive assembly 300 draws the first slide 301a greater distance than the second slide 302.
In addition, the degree of misalignment of the second guiding section 302a with respect to the first guiding section 301a (i.e. the longitudinal position of the transition breaking surface 302c) can be changed by pre-adjusting the longitudinal position of the second sliding member 302 in the second sliding slot 102b-1, so that the distance that the sliding buckle 303 can initially drive the first sliding member 301 to slide outward is changed. Therefore, the parallel groove clamp can clamp and fix the drainage wires with different outer diameters, and is suitable for the fire lapping operation of the drainage wires with different specifications.
