Abstract

The invention discloses a steel stranded wire clamping device, which mainly comprises a wedge-shaped traction plate and a wire clamping plate, wherein the upper side and the lower side of the wedge-shaped traction plate are wedge surfaces, and the front surface is provided with two grooves which are parallel to the upper wedge surface and the lower wedge surface respectively; the wire clamping plate consists of a C-shaped main plate, a clamping plate, an upper L-shaped guide block and a lower L-shaped guide block, the main plate is sleeved on the wedge-shaped traction plate, the opening parts of the main plate are positioned on the front surface of the traction plate, the upper guide block and the lower guide block are fixed on an upper part and a lower part of an open surface of the main plate respectively, a bent end head of the upper guide block and the lower guide block is positioned in an upper groove and a lower groove respectively, the clamping plate is fixed on the lower guide block, the upper end face of the clamping plate is in sliding fit with the lower wedge surface; and an arc groove and a tooth groove used for clamping and positioning a steel stranded wire are formed in a lower edge opening of an opening of the main plate and on the lower end face of the clamping plate respectively. The steel stranded wire clamping device is simple in structure, light in weight, and easy and convenient to operate, and can be used very safely and reliably.

Description

The steel strand wire fixing-line device

Technical field

The invention belongs to a kind of small appliances in the power line construction, what be specifically related to is a kind of steel strand wire fixing-line device.

Background technology

The steel strand wire fixing-line device is a kind of indispensable utensil in the construction of electric power, telecommunication line, be exhibition put or tensioning steel strand wire process in be used for the steel strand wire end is blocked so that to the utensil of its traction.Present steel strand wire fixing-line device all is four-bar linkage structure basically; Cable clamping interface on two wire clamps is parallel to each other up and down; The defective that this fixing-line device exists is: 1. steel strand wire skid in cable clamping interface easily, special because wind-force or other steadily the influence of factor tractive effort moment does not appear when suddenling change, steel strand wire skid on fixing-line device more easily; Even the meeting slippage, can cause tower to ruin the serious consequence that the people dies when serious; 2. its complex structure, one pair of fixing-line device generally is made up of nearly 30 parts, and parts are too many, and production cost and maintenance cost are all than higher.

Summary of the invention

The objective of the invention is to overcome the existing existing above-mentioned defective of steel strand wire fixing-line device, propose a kind of simple in structure, easy to operate, safe and reliable wedge shape steel strand wire fixing-line device.

The technical scheme that realizes above-mentioned purpose is: a kind of steel strand wire fixing-line device; Mainly form by wedge shape towing plate and card line plate; It is characterized in that: the both sides up and down of said wedge shape towing plate are wedge surface; Last wedge surface is a slope, and following wedge surface is a horizontal plane, the front of wedge shape towing plate have twice respectively with two grooves that wedge surface is parallel up and down; Said card line plate by " C " font mainboard, clamping plate and up and down two " L " shape guide pads form; Mainboard is sleeved on the wedge shape towing plate; Its opening is in the front of towing plate, in the following bead of mainboard opening clamping is arranged and locatees the arc groove of steel strand wire; Last guide pad is fixed on the top of mainboard opening surface, and the last groove that its bending termination is positioned at the wedge shape towing plate also slidably; The front of clamping plate is fixed on down on the inwall of guide pad, and the bending termination of following guide pad is positioned at said lower groove, and the following wedge surface of the upper surface of clamping plate and wedge shape towing plate forms and is slidingly matched, and there is the roller seating space of clamping steel strand wire the lower surface of clamping plate; The plate face middle part of " C " font mainboard is provided with a vertical bar hole, and the back side of clamping plate leans against on the inwall of mainboard through the stop screw in the bar hole.

The roller seating space of said clamping plate lower surface is " V " font.

After steel strand wire are stuck in the corresponding roller seating space of wedge shape towing plate and card line plate; During pulling wedge shape towing plate, clamping plate can be moved downward by the compressing of wedge shape towing plate, and steel strand wire are just clamped tightly; Along with the pulling force increase of wedge shape towing plate, steel strand wire can be held tightlyer.

Simple structure of the present invention, main element are less than ten, in light weight, easy and simple to handle, and the steel strand wire of clamping are pressed from both sides tight more more along with the pulling force increase, use as safe as a house, reliable.

Embodiment

Below in conjunction with accompanying drawing the present invention is described further.

As shown in Figure 1; Steel strand wire fixing-line device of the present invention mainly is made up of wedge shape towing plate 1 and card line plate; The both sides up and down of wedge shape towing plate 1 are wedge surface; Last wedge surface is a slope, and following wedge surface is a horizontal plane, and there is the last groove 2 and together with following wedge surface parallel lower groove 3 parallel with last wedge surface together in the front of wedge shape towing plate;

As shown in Figure 2; Card line plate is made up of the mainboard 4 (like Fig. 4, shown in 5) of " C " font, clamping plate 8, the last guide pad 6 of " L " shape and the following guide pad 7 of " L " shape; Mainboard 4 is sleeved on the wedge shape towing plate 1, and its opening is in the front of wedge shape towing plate 1.In the following bead of mainboard 4 openings clamping is arranged and locate the arc groove 10 (as shown in Figure 3) of steel strand wire; Last guide pad 6 is fixed on the top of mainboard 4 opening surfaces, and its bending termination is positioned at groove 2 also slidably; There is a screw hole at the back side of clamping plate 8; The front of clamping plate 8 is fixed on down on the inwall of guide pad 7; Following guide pad 7 bending terminations are positioned at lower groove 3; The following wedge surface of the upper surface of clamping plate 8 and wedge shape towing plate 1 forms and is slidingly matched, and there are " V " font roller seating space 12 (as shown in Figure 3) of clamping steel strand wire the lower surface of clamping plate 8; The plate face middle part of " C " font mainboard is provided with a vertical bar hole 5 (as shown in Figure 4); A stop screw 9 is installed in the bar hole 5; The termination of stop screw 9 is screwed in the screw hole at clamping plate 8 back sides; Clamping plate 8 back sides are leaned against on the inwall of mainboard 4, when wedge shape towing plate 1 moves forward and backward, clamping plate 8 can only along bar hole 5 do upper and lower displacement and can not before and after displacement.
