Description

Technical Field

[0001] This utility model relates to the field of power line installation technology, specifically to a temporary cable installation cable guide. Background Technology

[0002] During the construction of some projects, it is necessary to temporarily erect power lines. When slack wires pass through the crossing frame, they will rub against the frame, which can easily cause wear to the wire insulation. Therefore, a wire guide is used to erect the wires to cross the obstacle.

[0003] Publication (Announcement) No.: CN214280700U, a line crossing device for power engineering construction, which places the conductor on the line crossing device and uses the rotation effect of the friction-reducing drum to move synchronously with the conductor, thereby reducing the wear of the conductor and the insulating rod;

[0004] While the above solution allows for easy pulling and placing of the power cord, it is prone to falling off the cord release device when the cord sways due to wind or other forces. Utility Model Content

[0005] The present invention aims to at least solve the problem of limited protection effect on erected cables in the prior art.

[0006] This solution provides a temporary cable mounting cable guide, which is achieved by the following specific technical means: including a connecting rod, a rotating cylinder and a limiting ring, the top of the connecting rod is fixed with a protrusion, the front and rear walls of the protrusion are provided with a communicating horizontal hole, the rotating cylinder is placed horizontally and the middle and lower part passes through the horizontal hole, the upper part of the rotating cylinder is located above the protrusion, and a conical wheel is fixedly sleeved on the rotating cylinder;

[0007] Meanwhile, the protrusion is provided with an arc-shaped hole, the two ends of which extend to the top wall of the protrusion and are located on both sides of the rotating cylinder. The lower part of the limiting ring passes through the arc-shaped hole, and there is a notch section on the limiting ring, through which the cable can be inserted into the limiting ring.

[0008] Preferred technical solution 1: Two sets of horizontal arms are rotatably sleeved on the connecting rod in the height direction, and a vertical shaft is fixed at the end of the horizontal arm. A set of protrusions is also used to install at the top of the vertical shaft. By rotating the angle of the horizontal arm, the three sets of protrusions can be kept on the same straight line or form a certain angle, which is used to straighten the wires or set the angle as needed.

[0009] Preferred technical solution 2: A sleeve is fixed at the lower end of the connecting rod, and the sleeve is used to fit onto the upright.

[0010] Preferred technical solution 3: The front and rear walls of the bracket are fixed with protruding plates on the left and right sides of the rotating cylinder. A support roller rotates between the two sets of protruding plates. At the same time, a set of support rollers is also rotatably installed in the notch opened on the top wall of the bracket. All three sets of support rollers are in contact with the inner wall of the rotating cylinder and cooperate to support the rotating cylinder.

[0011] Preferred technical solution four: The side of the conical wheel is close to the inner wall of the limiting ring, and the gap is smaller than the diameter of the cable, so as to prevent the wire from getting stuck in the gap between them.

[0012] Preferred technical solution five: The length of the arc-shaped hole is greater than the length of the notch segment, so that when the notch segment moves into the arc-shaped hole, the limiting ring is still partially in the arc-shaped hole.

[0013] The above structure gives this solution the following advantages:

[0014] 1. A simple structural combination, such as a rotating drum, conical wheel, and limiting ring, can easily achieve non-clamping cable installation, which facilitates cable pulling and placement while effectively preventing accidental cable drops;

[0015] 2. By adjusting the relative positions of multiple sets of brackets, the wires can be laid straight or at a set angle as needed. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 A temporary cable guide includes a connecting rod 1, a rotating drum 2, and a limiting ring 3. A protrusion 4 is fixed to the top of the connecting rod 1. The protrusion 4 has a communicating horizontal hole 41 on its front and rear walls. The rotating drum 2 is placed horizontally, with its lower middle part passing through the horizontal hole 41. The upper part of the rotating drum 2 is positioned above the protrusion 4. A conical wheel 5 is fixedly fitted onto the rotating drum 2, causing the conical wheel 5 to rotate on the protrusion 4. Simultaneously, an arc-shaped hole 42 is provided on the protrusion 4, with both ends extending to the top wall of the protrusion 4 and located... On both sides of the rotating drum 2, the lower part of the limiting ring 3 passes through the arc-shaped hole 42. The inner wall of the limiting ring 3 is covered with an elastic pad. At the same time, the limiting ring 3 also has a notch section. The cable can be put into the limiting ring 3 through the notch section. The length of the arc-shaped hole 42 is greater than the length of the notch section, so that when the notch section moves into the arc-shaped hole 42, part of the limiting ring 3 is still in the arc-shaped hole 42. The side of the conical wheel 5 is close to the inner wall of the limiting ring 3, and the gap is smaller than the diameter of the cable to prevent the wire from getting stuck in the gap between them.

[0025] Before placing or removing the cable, rotate the limiting ring 3 to move the notch section to the upper middle part of the limiting ring 3 and away from the arc-shaped hole 42. At this time, the wire can be placed into the limiting ring 3 from the notch section and carried by the conical wheel 5, or the cable carried by the conical wheel 5 can be taken out from the notch section. After the operation is completed, rotate the limiting ring 3 again to slide in the arc-shaped hole 42, so that the notch section moves into the arc-shaped hole 42 for hiding. At this time, the limiting ring 3 and the conical wheel 5 provide 360° protection for the cable, effectively avoiding the risk of the cable falling when it shakes.

[0026] Please see Figures 1-5 The cable temporary installation cable guide has two sets of horizontal arms 6 mounted on the connecting rod 1 in the height direction, and a vertical shaft 7 is fixed at the end of the horizontal arm 6. A set of protrusions 4 are also fixedly installed at the top of the vertical shaft 7. By rotating the angle of the horizontal arm 6, the three sets of protrusions 4 can be kept on the same straight line or form a certain angle, which is used to install the wires straight or at a set angle as needed.

[0027] A sleeve 8 is fixed at the lower end of the connecting rod 1. The sleeve 8 is used to insert onto the upright and is assembled and fixed by tightening bolts provided in the threaded holes on the sleeve 8 wall. The cross arm 6 is also fixed by contacting the connecting rod 1 through tightening bolts installed in its threaded holes.

[0028] Please see Figures 1-5 The cable temporary cable guide is installed. The front and rear walls of the bracket 4 are fixed with convex plates 9 on the left and right sides of the rotating drum 2. A support roller 10 rotates between the two sets of convex plates 9. At the same time, a set of support rollers 10 is also rotatably installed in the notch opened on the top wall of the bracket 4. All three sets of support rollers 10 are in contact with the inner wall of the rotating drum 2 and cooperate to support the rotating drum 2, so that the rotating drum 2 can rotate smoothly. At the same time, the setting of the convex plates 9 can also limit the left and right directions of the rotating drum 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
