Abstract

The utility model relates to a cable installing pulley, particularly a device for installing power cables, which is composed of a plurality of arc-shaped nylon molded slices with built-in steel balls and forms a circular shape and is sheathed outside the cables. When the utility model is used, the cable installing pulley is drawn, the damage to insulation caused by the blockage and deformation of cables can be avoided, and the quality of the cable installing project and the speed of the construction can be improved.

Description

Cable send the cable pulley

The utility model belongs to the cable laying equipment technical field.

In the power cable laying project, now prolong with traditional working method always, promptly affect cable with the strand grinding machine, cable is dragged to the appointed place along the cast-iron pipe that has laid by active well.Because the power cable diameter is big, Heavy Weight, bending radius is big, the oversheath coefficient of friction is big, often in the construction make and insulate corrupted and influence construction schedule because of dilatory improper or jam cause cable cover(ing) and internal core distortion, cause integral construction impaired.

For this reason, the utility model has been released a kind of new cable laying device, its objective is the ring-type pulley gear that the multi-disc arc nylon matrix that utilizes built-in ball is combined into, and is enclosed within outside the cable laying, to reduce the frictional force of dilatory cable, realize carrying out smoothly of power cable laying project.

The related cable of the utility model send cable pulley structure in the form of a ring, is connected by the arcuation nylon matrix of multi-disc unified specification to combine.The quantity of matrix determines that according to the size of the sending outside diameter of cable matrix structure is suitable for the dismounting combination.

Nylon matrix upper/lower terminal is a semicircular body, and a hole is respectively arranged on it; Matrix one side is a spill, and lug is respectively arranged up and down, and is porose on the lug, is convenient to assemble mutually with another matrix with bolt; The opposite side of sheet is a convex body, and is also porose on it, is convenient to link with bolt and another matrix; There is circular groove at the middle part of matrix, and there is cylindrical projection in the central authorities of groove, and the cylindrical projection outer rim has screw thread, and there is a semicircle pit in the central authorities of cylindrical projection, places the steel ball in the pit.The nylon FE Tiler that screws is arranged on the cylindrical projection, make securing member, prevent that the steel ball from coming off.Send the cable pulley by what the nylon matrix assembled, the pedestal that is equivalent in the bearing is enclosed within the cable outside, with nylon rope several cable pulleys that send is connect in the holes at two ends up and down mutually through matrix during towing cable, draws when sending the cable pulley, and cable again can the stress deformation damage.

The cable that the utility model relates to send the cable pulley to solve cable in the power cable laying project to be difficult to the problem that drags in pipeline, to have guaranteed construction quality and improved speed of application and efficient.In the construction, for preventing to send cable pulley damage cable, and prevent to send relative displacement between cable pulley and cable, clog sending to twine with numb strap between cable pulley and cable.

Fig. 1 send cable pulley structure schematic diagram for cable.Among the figure, 1-matrix, 2-semicircular body, 3-semicircle body opening, 4-lug, 5-lug hole, 6-convex body, 7-FE Tiler, 8-circular groove, 9-cylindrical projection, 10-semicircle pit.

Fig. 2 is single matrix structural representation.Among the figure, 2-semicircular body, 3-semicircle body opening, 4-lug, 5-lug hole, 6-convex body, 7-FE Tiler, 11-ball, 12-convex body hole.

Now in conjunction with the accompanying drawings further technical descriptioon is done in enforcement of the present utility model.As shown in the figure, cable send cable pulley structure in the form of a ring, is combined by arcuation matrix 1.Matrix about in the of 1 two ends be semicircular body 2, on the semicircular body porose 3.Matrix one side is a spill, and opposite side is a convex, and concave portions up and down two ends has lug 4, and is porose 5 on the lug, and porose 12 on the convex part convex body 6, the hole 5 on the concave portions lug is big or small identical with the hole 12 on the convex part convex body.Interconnecting of a plurality of matrixs is combined into the circulus that cable send the cable pulley.During assembling, the convex body 6 of the concave portions recess of matrix and adjacent die convex part connects, and passes lug hole 5 and convex body hole 12 is fixed by bolt.There is circular groove 8 at the matrix middle part, and there is cylindrical projection 9 in groove central authorities, and cylindrical projection 9 outer rims have screw thread, and there is semicircular recess 10 in cylindrical projection 9 central authorities, place ball in the semicircular recess 10, screw FE Tiler 7 on the cylindrical projection.
