Abstract

The invention discloses a multifunctional instant aluminum alloy grip strength strain clamp. A hub clamping piece and a tube plug are formed through high-strength aluminum alloy die casting; a circular-truncated-cone tube, which is formed through high-strength malleable aluminum alloy die casting, is taken as a tube body of the multifunctional instant aluminum alloy grip strength strain clamp; and a radial pull plate and a U-shaped pull rod, of the multifunctional instant aluminum alloy grip strength strain clamp, are respectively made of aluminum alloy sectional materials and stainless steel bars. Firstly, the tube body is inserted into the center hole of the radial pull plate; then the hub clamping piece, a spring and the pipe plug are sequentially put into the tube body and the pipe plug is fixed through a pin; and finally the U-shaped pull rod is inserted into the round holes in two sides of the radial pull plate, and is fixed through a screwed nut and an anti-slip pin. The hub clamping piece adopted by the multifunctional instant aluminum alloy grip strength strain clamp is characterized in that screw thread thorns are arranged inside; the cross section takes the shape of petals (the quantity of the petals depends on the model of the multifunctional instant aluminum alloy grip strength strain clamp); a slotting is formed in the axial direction; and the hub tube body is circular-truncated-cone-shaped. The principle adopted by the multifunctional instant aluminum alloy grip strength strain clamp is grip strength which is characterized in that the stress is uniform; the friction coefficient is great; a cable does not deform under the stress and can be instantly gripped when inserted into the multifunctional instant aluminum alloy grip strength strain clamp; the withdrawing resistance of the cable is increased; the tensile strength is improved; and cable does not withdraw.

Description

Multi-functional quick aluminium alloy grip strain clamp

Affiliated technical field

The invention belongs to electric armour clamp distribution equipment

Background technology

At present, carbon fiber complex core aluminium strand cable progressively substitutes traditional steel core cable in power industry, and original quick aluminium alloy strain clamp can not satisfy the pulling force requirement of carbon fiber complex core aluminium strand cable, has the practical problem that can't clip cable, moves back line.

Summary of the invention

In order to solve the problem that quick aluminium alloy strain clamp in use can't clip cable, moves back line, the invention provides a kind of multi-functional quick aluminium alloy grip strain clamp, the aluminium alloy strain clamp can't clip cable to solve in the construction of transmission of electricity stringing fast, move back the problem of line, reaches safety, purpose efficiently.

The present invention's technical scheme that adopts of dealing with problems is: adopt the inside of high-strength aluminum alloy die cast that the screw thread thorn is arranged, the cross section is petal (the different petal quantity of model according to multi-functional quick aluminium alloy grip strain clamp does not wait), axially have and to crack, the flower-drum folder of truncated cone-shaped body, adopt the high strength Aluminium wrought alloy to be pressed into the Rotary-table pipe as the body of multi-functional quick aluminium alloy grip strain clamp (hereinafter to be referred as strain clamp), adopt the pipe plug of high-strength aluminum alloy die casting strain clamp, make the radially arm-tie of strain clamp of aluminium alloy extrusions, make the U-shaped pull bar with stainless steel bars, at first the mesopore of body from arm-tie radially inserted, the flower-drum folder of packing into successively in the body then, spring, pipe plug, with the location pin pipe plug is fixed, U-shaped pull bar two ends are inserted two mother rib lateral rotundums from the another side of arm-tie radially, tighten with nut at the pull bar two ends, fixes with anti-skidding pin; The inner flower-drum folder that adopts of strain clamp, be folder inside have screw thread thorn, cross section be petal (the different petal quantity of model according to strain clamp do not wait), axially have crack, truncated cone-shaped flower-drum body, the principle that adopts is grip, grip is stressed evenly, coefficient of friction is big, cable is indeformable in loading process, cable inserts folder and holds at once, increase simultaneously and move back the line resistance, improve tensile strength, thereby solve the practical problem that quick aluminium alloy strain clamp in use can't clip cable, moves back line.

The invention has the beneficial effects as follows that the mechanical strength height adopts the flower-drum folder, prevent that quick aluminium alloy strain clamp from use can't clip cable, moving back the problem of line, safe and efficient.

Embodiment

In Fig. 3, body (1) inserts the radially mesopore of arm-tie (3), the flower-drum folder (2) of packing in the body then, flower-drum folder (2) is that inside has the screw thread thorn, the cross section is petal (the different petal quantity of model according to strain clamp does not wait yet), axially have and crack, truncated cone-shaped flower-drum body, axial cracking as seen from Figure 4, Fig. 5 can see truncated cone-shaped flower-drum body, can see inner screw thread thorn from Fig. 6 A-A profile, Fig. 7 can see the cross section petal shape, pack in the body again spring (4) and pipe plug (5), pipe plug is fixing with location pin (10), the two ends of U-shaped pull bar (6) are inserted the circular hole of both sides from arm-tie (3) another side radially, pad (9) back is loaded onto at two ends, and each is tightened with two nuts (8), use anti-skidding pin (7) fixing again, like this, a multi-functional quick aluminium alloy grip strain clamp (hereinafter to be referred as strain clamp) is with regard to installation; With cable conductor termination wiring tighten, have one's hair trimmed with client cables in the construction, the end is neat, slick and sly with the file finishing, remove wiring, front end is straight, removes dirt, and " flower-drum folder (2) " in the strain clamp light power is pressed, make its free slippage in body, strain clamp osculum center is aimed in the cable conductor termination slowly insert, draw from big end tailstock until lead, lead is stopped wire jumper length and is stopped to insert, spring promotes wire clamp and discharges clamping wire automatically.Firmly lead tension back is painted at wire clamp osculum end lead and be the visible marking, be convenient to check.
