Abstract

The utility model relates to the cable installation technique, in particular to a right-angle cable guide device, which solves the problem of cable damage or jamming during cable installation work, especially occasions of complicated terrain, long distance and need of vertically changing cable tension direction. The right-angle cable guide device is characterized in that a frame is of a frame structure composed of two mutually parallel ring quarters, a plurality of guide rollers are arranged along an arc of the quarter of circular frame, a guide barrel is arranged at one end of the arc of the quarter of circular frame, and a center line of the guide barrel is positioned at a tangential position of one guide roller closest to the guide barrel. Cables are distributed in two mutually perpendicular directions, since the perpendicular direction is often in the air, the cables are led out from the guide barrel after passing through the plurality of guide rollers, and since the tangential directions of the guide rollers are positioned in a through hole of the guide barrel, wearing of cable protective layers due to direct contact between the cables and the guide barrel or other parts of a support can be avoided.

Description

Cable square wire installation

Technical field

The utility model relates to the cable mounting technique, relates in particular to a kind of complex-terrain, needs the vertical cable square wire installation that changes stayguy direction.

Background technology

When cable is installed because distance is all long, directly dilatory from ground can the damage cable covering, and the clip phenomenon can take place when running into barrier such as crack of stone, branch, if untimely processing may be broken cable and be caused security incident.Therefore, people have designed multiple wire installation when cable is installed, and these apparatus structures are different, and characteristics are respectively arranged.As patent publication No. is that one kind of CN101194124A is used for the equipment that pilot cable or lead pass wall, this equipment has the retainer that is connected with two or more cable beareves, wherein, retainer is the frame form around ferrule openings, and cable bearer is arranged in the scope of this ferrule openings, for in such equipment, improving easiness is installed, at least one cable bearer or at least two group cable beareves can irrespectively be connected with retainer by the Connection Element that sets for cable bearer with remaining cable bearer respectively.And for example patent publication No. is that one kind of CN2497455Y is with the basket cable guiding device, mainly form by two steel wire rope tracks and a lead movable pulley, article two, the steel wire rope track is arranged on contiguous position with the basket cable, parallel involving between upper and lower two crossbeams of lift body frame from top to bottom,, one side of lead movable pulley is fixed a support, have two parallel sliding tracks on the support, the steel wire rope track is worn just and is passed through in this parallel sliding track, walks around the lead movable pulley with the basket cable and involves between entablature and hanging basket.This device can be made in order with the basket cable, prevents to beat strand or colluded extension by his thing with the basket cable, reaches purpose safe in utilization.Be that CN101189761A conductor jointer that is used for high voltage power cable is arranged in sleeve pipe also just like patent publication No., conductor jointer comprises the threaded connector of the conduction of hollow cylinder, threaded connector has the radial screw bore of the contact bolt that is used for same conduction, and the contact bolt can be squeezed in having on the cable core of removing insulating barrier that inserts with gap at two ends of high voltage power cable.Threaded connector is separated at least two fan-shaped section by section in axial direction, and fan-shaped section forms the bearing that is used to contact bolt that can radially regulate.

Summary of the invention

The purpose of this utility model is in order to solve in the cable installation work, especially distance, need vertically when changing stayguy direction, electric wire is caused damage or the problem of clip takes place.Provide a kind of rational in infrastructure simple, easy to carry, satisfy complex-terrain and use, utilize a plurality of rolling type guide wheels, have and prevent that cable from running out of the cable square wire installation outside the guide wheel with vertical change direction.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cable square wire installation, comprise frame, it is characterized in that the frame structure that described frame is made up of two quadrants that are parallel to each other, camber line along quadrant shape framework is provided with several deflector rolls, end at quadrant shape framework camber line is provided with guide cylinder, and the center line of guide cylinder is positioned at apart from the tangent position of the nearest deflector roll of guide cylinder.Carrying out cable at orthogonal both direction lays; vertical direction generally is in state high up in the air; cable is drawn from guide cylinder after by several deflector rolls; because the tangential direction of deflector roll is arranged in the through hole of guide cylinder, does not directly contact with other position of guide cylinder or support and cause the cable protective layer to wear and tear so can not produce cable.

As preferably, described several deflector rolls are parallel to each other, and deflector roll is provided with the roller of arcs of recesses metallic channel, apart from the minimum point height of the nearest roller concave arc minimum point of guide cylinder than guide cylinder internal diameter.The axis of several deflector rolls all designs on same circular arc line, design in parallel to each other then, and cable moves along roller arcs of recesses metallic channel when dragging, and by the rolling friction drive cable of roller, resistance is little flexibly.

As preferably, the roller endoporus two ends of described deflector roll are respectively equipped with bearing, are provided with mandrel in the bearing, mandrel and bearing interference fit, and the two ends of mandrel are fixed on the framework of frame quadrant shape, and the outside of bearing is provided with end cap.This is a kind of version of deflector roll, needs only the two ends spiral-lock of mandrel fixing on frame when this form is installed.

As preferably, the radius of curvature at the place, high-order bit of the arcs of recesses metallic channel of roller is big in the radius ratio deflector roll of the quadrant shape framework that two of described frames are parallel to each other.The circular frame of frame plays a part to stop jumps out framework about cable.

Effective effect of the present utility model is: the cable that is fit to vertical shaft, right angle, multi-angle turning drags guiding, has avoided cable to be subjected to the clip damage in the unwrapping wire process, and is easy to carry, and good stability is practical.
