Description

Technical Field

[0001] The present invention belongs to the field of cable installation, and more specifically, it is a communication cable installation device. Background Art

[0002] Communication cables are thicker than power supply cables. During the erection process, they require more solid support. Brackets are often installed on adjacent walls with expansion bolts, and then the communication cables are fixed to the brackets. Usually, clips suitable for the cables are used for fixation, and the size of the clips needs to be changed according to the thickness of the cables, which is inconvenient to use. At the same time, the installation operation of the clips is cumbersome, and bolts are required to fix the clips; moreover, the diameter of the clips cannot change. When the cable expands due to heat, the clips are likely to pinch and break the cable. Although the current in communication cables is usually small, when used for a long time or when multiple cables are densely laid, heat accumulation will also cause the temperature to rise significantly, resulting in cable expansion; if the communication cable is in a high-temperature environment, such as near a heat source or outdoors in high temperature, the cable will absorb environmental heat and the temperature will rise, causing expansion; to solve the above problems, we have invented a communication cable installation device.

Detailed implementation manners

[0016] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0017] A communication cable installation device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, it includes a base 1. Two horizontal pipes 3 are fixedly installed on the base 1 through columns 2. The two horizontal pipes 3 are symmetrically distributed left and right and are parallel to each other. It is characterized in that: a moving rod 4 is arranged below the two horizontal pipes 3, and a moving plate 5 is movably arranged below the moving rod 4. Corresponding to the columns 2, the moving plate 5 is respectively provided with reserved holes, and the columns 2 are slidably located in the corresponding reserved holes, which can increase the stability of the up and down movement of the moving plate 5. An adjusting device capable of adjusting the height of the moving plate 5 is arranged on the base 1. A plurality of piston cylinders 6 are fixedly arranged on the moving plate 5. Piston plates 7 are hermetically fitted in the piston cylinders 6 respectively. The piston plates 7 and the moving rod 4 are respectively fixedly connected through piston rods 8. The piston plates 7 and the piston cylinders 6 are respectively connected through return springs 9. The return springs 9 are sleeved on the outer circumferences of the corresponding piston rods 8. One end of the return spring 9 is fixedly connected to the corresponding piston plate 7, and the other end is fixedly connected to the corresponding piston cylinder 6. Both ends of the horizontal pipe 3 are closed to form cavities, and the interiors of the cavities are respectively connected and communicated with the interiors of the piston cylinders 6 through connecting pipes 10. The two ends of a fastening rope 11 are fixedly connected to the side surface of one of the horizontal pipes 3. The two ends of the fastening rope 11 are distributed front and back. One end of the fastening rope 11 is fixedly connected to the front part of the horizontal pipe 3, and the other end is fixedly connected to the rear part of the horizontal pipe 3. A stop rod 12 is fixedly arranged on the side surface of the other horizontal pipe 3. The stop rod 12 is located in the middle of the horizontal pipe 3. The middle part of the fastening rope 11 can hook the stop rod 12. The structure of the present invention is simple and ingenious. The cable is fixed by the helically wound fastening rope, which can adapt to cables of various diameters and is convenient to use; and it can utilize the heat generated when the cable expands thermally to automatically adjust the force of the fastening rope to fix the cable, reduce the breakage of the cable, can meet the actual needs, and is suitable for popularization.When using the present invention, first, the base 1 is fixedly installed at an appropriate position, and then the communication cable to be fixed is placed on the two horizontal pipes 3, and the communication cable is arranged parallel to the horizontal pipes 3. Then, the fastening rope 11 is spirally wound around the outer periphery of the communication cable, the horizontal pipes 3 and the moving rod 4. The spiral directions of the front and rear parts of the fastening rope 11 are opposite. When the communication cable moves back and forth, the fastening rope 11 on one side can be tightened, wound more tightly, reducing the movement of the communication cable until the middle part of the fastening rope 11 just hangs on the blocking rod 12, completing the winding of the fastening rope 11. At this time, the adjusting device is provided to move the moving plate 5, so that the moving plate 5 moves downward. The moving plate 5 drives the piston cylinder 6, the piston plate 7, and the piston rod 8 to move downward through the moving rod 4. At this time, the return spring 9 may not be compressed. The moving rod 4 forms a downward pulling force on the lower part of the spiral fastening rope, so that the spiral fastening rope is further tightened, and the communication cable is closely attached to the upper parts of the two horizontal pipes 3 and the spiral fastening rope, completing the fixation of the communication cable. When the communication cable expands due to heat, the heat of the communication cable is transferred to the horizontal pipe 3, causing the air in the horizontal pipe 3 to expand due to heat and be transferred to the inside of the piston cylinder 6 through the connecting pipe 10, causing the gas between the piston cylinder 6 and the piston plate 7 to expand due to heat, thereby pushing the piston plate 7 to move upward relative to the piston cylinder 6. The piston plate 7 drives the piston rod 8 and the moving rod 4 to move upward, and the return spring 9 is compressed. The pulling force of the moving rod 4 on the fastening rope 11 is reduced, so that the diameter of the spiral fastening rope formed by the fastening rope 11 increases to adapt to the increased diameter of the communication cable due to heat expansion. The fixing and fastening force of the fastening rope 11 on the communication cable changes little, avoiding hard contact between the communication cable and the fastening rope 11 when the communication cable expands due to heat, reducing damage to the communication cable, and at the same time preventing the communication cable from falling off from the fastening rope 11. When the temperature of the communication cable drops again, the above process is carried out in reverse order, and the return spring 9 makes the piston plate 7 move downward to reset, and the fastening rope 11 keeps the communication cable fastened and fixed.

[0018] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the adjusting device in this embodiment includes a support rod 20. The support rod 20 is fixedly installed on the base 1. A slide rod 21 is fixedly installed on the support rod 20. A sleeve 22 is slidably installed on the slide rod 21. The sleeve 22 can only slide left and right along the slide rod 21. The slide rod 21 is a square rod. A spring 23 is connected between the sleeve 22 and the support rod 20. The spring 23 is sleeved on the outer periphery of the slide rod 21. One end of the spring 23 is fixedly connected to the sleeve 22, and the other end is fixedly connected to the support rod 20. A coaxial toothed ring 24 is rotatably installed on the outer periphery of the sleeve 22 through a one-way bearing. A strip-shaped rack 25 is meshed and cooperated on one side of the toothed ring 24. The strip-shaped rack 25 is fixed on the moving plate 5. When manually adjusting the movement of the moving plate 5 and making the moving plate 5 move downward relative to the base 1, the moving plate 5 drives the strip-shaped rack 25 to move downward. The strip-shaped rack 25 drives the toothed ring 24 to rotate forward. At this time, the one-way bearing does not prevent the toothed ring 24 from rotating. The toothed ring 24 rotates relative to the sleeve 22, and the sleeve 22 and the slide rod 21 do not rotate. When the moving plate 5 is released, due to the effect of the one-way bearing, the moving plate 5 and the strip-shaped rack 25 cannot move upward to reset. At this time, the toothed ring 24 cannot rotate reversely relative to the sleeve 22. At this time, the moving plate 5 can only move downward. When it is necessary to move the moving plate 5 upward to reset, push the sleeve 22 to the right, and the spring 23 is compressed, so that the toothed ring 24 is separated from the strip-shaped rack 25. At this time, the moving plate 5 can move upward to reset.

[0019] Specifically, as Figure 2 shown in the figure, a collar 30 is fixedly installed in the middle of the fastening rope 11 in this embodiment. The collar 30 can be sleeved on the outer periphery of the stop rod 12. The collar 30 divides the fastening rope 11 into front and rear parts. When the collar 30 is sleeved on the outer periphery of the stop rod 12, the spiral fastening rope wound around the outer periphery of the cable is divided into front and rear parts. When the cable moves back and forth relative to the horizontal pipe 3, the friction between the cable and the fastening rope 11 is utilized to drive the spiral fastening rope to move forward or backward, so that the spiral fastening rope is tightened, increasing the fixing force on the communication. The collar 30 divides the fastening rope 11 into front and rear parts. Therefore, the fastening ropes 11 in both the front and rear parts are tightened. And if one side of the fastening rope 11 is damaged, it does not affect the function of the fastening rope 11 on the other side of the collar 30.

[0020] Furthermore, as Figure 1 and Figure 2 shown in the figure, a row of several cross bars 40 are respectively fixedly installed on the opposite sides of the two horizontal pipes 3 in this embodiment. When the fastening rope 11 is fixedly wound around the cable, the fastening rope 11 only passes between two adjacent cross bars 40 in the front and rear once. That is, when the fastening rope 11 is spirally wound around the outer peripheries of the cable and the horizontal pipe 3, the cross bars 40 separate the fastening rope 11, increasing the uniformity when the fastening rope 11 is spirally wound, so that the winding force of the fastening rope 11 on the cable is more evenly distributed.

[0021] Even further, as Figure 1 and Figure 2As shown, several mounting holes 50 are provided on the base 1 in this embodiment. The base 1 is fixed in place by using bolts through the mounting holes 50.

[0022] Furthermore, as Figure 1 , Figure 2 and Figure 4 shown, a small piston cylinder 60 is fixedly installed on the piston plate 7 in this embodiment. A through groove 61 communicating with the small piston cylinder 60 is provided on the piston plate 7. The lower part of the piston cylinder 6 is connected to the lower part of the small piston cylinder 60 through the through groove 61. A piston 62 is hermetically and slidably installed in the small piston cylinder 60. The diameter of the through groove 61 is smaller than the diameter of the piston 62, so the piston 62 will not slide out of the small piston cylinder 60. A push rod 63 is fixedly installed on the piston 62. The push rod 63 is slidably installed on the small piston cylinder 60. A chute 64 is provided in the upper part of the piston cylinder 6. A stopper 65 is slidably installed in the chute 64. The stopper 65 can only slide left and right in the corresponding chute 64. The stopper 65 is connected to the piston cylinder 6 by a tension spring 66. The tension spring 66 is sleeved on the outer periphery of the stopper 65. One end of the tension spring 66 is connected to the stopper 65, and the other end is connected to the piston cylinder 6. The top side of the small piston cylinder 60 abuts against and contacts the bottom side of the stopper 65. A guiding inclined surface 67 is provided on the side surface of the stopper 65. The upper end of the push rod 63 contacts and cooperates with the guiding inclined surface 67. When the air pressure at the lower part of the piston cylinder 6 increases, since the bottom side of the stopper 65 contacts and cooperates with the top side of the small piston cylinder 60, the upward movement of the piston plate 7 relative to the piston cylinder 6 is restricted. At this time, the air pressure in the small piston cylinder 60 increases, and the piston 62 moves upward relative to the small piston cylinder 60. The piston 62 drives the push rod 63 to move upward. The upper end of the push rod 63 slides along the guiding inclined surface 67, giving a lateral thrust to the stopper 65. The stopper 65 gradually moves away from the upper part of the small piston cylinder 60, and the tension spring 66 is stretched and stores energy. At this time, the piston plate 7 can drive the small piston cylinder 60 to move upward, and at the same time, the piston rod 8 and the moving rod 4 move upward; when the air pressure in the piston cylinder 6 drops and returns to normal, the above process proceeds in reverse order. The piston plate 7 moves downward and resets relative to the piston cylinder 6. The stopper 65 resets under the elastic pulling force of the tension spring 66. The bottom side of the stopper 65 contacts and cooperates with the top side of the small piston cylinder 60 again, restricting the upward movement of the piston plate 7, thereby avoiding the situation that the piston plate 7 moves upward relative to the piston cylinder 6 due to the excessive tightening force of the fastening rope 11 on the cable.

[0023] Furthermore, as Figure 2 shown, a threaded through hole 70 is provided on the moving plate 5 in this embodiment. A bolt 71 is threadedly installed in the threaded through hole 70. After adjusting the moving plate 5 to move downward to an appropriate position, then turn the bolt 71 so that the lower end of the bolt 71 abuts against and contacts the top side of the base 1, preventing the moving plate 5 from moving downward continuously.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
