Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a cable installation structure for power transmission towers. Background Technology

[0002] Power transmission towers are tower-shaped structures used for power transmission. Their structural characteristic is that all tower types are space truss structures, with members mainly composed of single equilateral angle steel or composite angle steel. When installing cables on power transmission towers, cable mounting structures are needed to secure the external cables, ensuring stable placement and use.

[0003] In traditional cable installation systems, fasteners and bolts are mostly used to secure cables. This requires clamping the cable with the fasteners and then tightening it with bolts. This necessitates workers carrying a number of bolts and tightening tools. During the tightening process, bolts or tools are easily lost, reducing the efficiency of cable installation. Therefore, this solution provides a cable installation structure for power transmission towers to address these problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a cable installation structure for power transmission towers is provided. This technical solution addresses the issues raised in the background section.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable mounting structure for a power transmission tower includes a mounting frame. Inside the mounting frame are a placement seat and a clamping seat, with a cable positioned between them. A through slot is formed on the right side of the top of the mounting frame, and a protective shell is fixedly connected to the mounting frame above the through slot. A pair of fixing slots are formed at both the front and rear ends of the mounting frame. A protrusion is fixedly connected to the placement seat near the fixing slot, and the protrusion is located inside the fixing slot. A spring is fixedly connected between the fixing slot and the protrusion. A fixing rod is provided on the upper side of the clamping seat, with both ends fixedly connected to the inner walls of both sides of the mounting frame. A rotating sleeve is fitted onto the fixing rod, and a connecting rod is fixedly connected to the rotating sleeve. One end of the connecting rod is rotatably connected to a connecting seat, which is fixedly mounted on the clamping seat. A sliding groove is formed through the middle of the connecting rod, and a guide rod is slidably connected inside the sliding groove. The guide rod is fixedly connected to the placement seat. A locking mechanism for limiting the clamping seat is provided inside the mounting frame.

[0007] Preferably, the placement seat is located on the lower side of the extrusion seat, and both the placement seat and the extrusion seat are fixedly connected to the end near the cable with an anti-slip pad.

[0008] Preferably, the locking mechanism includes a pair of slide rods fixedly connected to the inner wall of the fixed frame, a pair of slide blocks slidably connected to the surface of the slide rods, a rack fixedly connected to the lower end of the slide blocks, a pressing block fixedly connected to the lower end of the rack, and a driving member for driving the rack to rotate on the upper side of the rack.

[0009] Preferably, the driving component includes a gear meshing with a rack, the gear being rotatably mounted inside a through groove via a drive shaft, a worm gear fixedly connected to the drive shaft on one side of the gear, a worm being meshed with the worm gear, the worm being rotatably mounted inside a protective housing, and the front end of the worm penetrating through the protective housing and fixedly connected to a knob.

[0010] Preferably, a positioning rod runs through the knob, and the protective shell has several sets of slots that are compatible with the positioning rod.

[0011] Preferably, mounting brackets are fixedly connected to both the front and rear sides of the upper end of the fixed frame.

[0012] Compared with the prior art, this utility model proposes a cable installation structure for power transmission towers, which has the following features:

[0013] Beneficial effects:

[0014] 1. In use, this utility model lifts the protrusions on both sides, causing the placement seat to move upwards. After the placement seat moves upwards, the guide rod lifts the connecting rod, causing the connecting rod to rotate around the fixed rod, thereby lifting the compression seat and separating the placement seat from the compression seat. This facilitates placing the cable on the placement seat. After placement, the protrusions are released, and under the combined action of the cable's own weight and the spring, the lower placement seat moves. Through the cooperation of the guide rod and the connecting rod, the compression seat moves, allowing the compression seat to initially clamp the placed cable in conjunction with the placement seat. During the clamping process, the greater the downward tension of the cable itself, the greater the clamping force of the compression seat on the upper side of the cable, and the greater the gripping force on the cable. With the anti-slip pad, the clamping effect on the cable is further improved. The overall structure of this device is simple, easy to use, and improves work efficiency.

[0015] 2. This utility model includes a locking mechanism. After activation, the locking mechanism drives the rack to move via a drive component. When the drive component is activated, rotating the knob drives the worm gear to rotate, which in turn drives the lower worm wheel to rotate. The worm wheel then drives the left gear to rotate, which in turn drives the lower rack to move back and forth. The rack's movement further drives the lower pressing block to move, causing its lower end to abut against the clamping seat, thus limiting the pressing block's position. The self-locking property of the worm gear and worm wheel ensures the pressing block remains stable and does not loosen, allowing the placement seat and pressing seat to maintain clamping force for a long time, preventing the cable from being pulled back due to external vibrations and thus preventing cable disconnection. Simultaneously, by moving the positioning rod, one end of the positioning rod is inserted into the slot, further securing the knob and ensuring the stability of the locking mechanism.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art.

[0024] Reference Figure 1-3 As shown, the device includes a mounting frame 1, inside which are a placement seat 2 and a pressing seat 3. A cable 4 is installed between the placement seat 2 and the pressing seat 3. A through groove 102 is formed through the top right side of the mounting frame 1. A protective shell 9 is fixedly connected to the mounting frame 1 on the upper side of the through groove 102. Several sets of slots 901 are formed through the front end of the protective shell 9. A pair of fixing grooves 101 are formed through both the front and rear ends of the mounting frame 1. A protrusion 201 is fixedly connected to the placement seat 2 near the fixing groove 101, and the protrusion 201 is located inside the fixing groove 101. A spring 202 is fixedly connected to the protrusion 201. A fixing rod 7 is provided on the upper side of the extrusion seat 3. The two ends of the fixing rod 7 are fixedly connected to the inner walls of the two sides of the fixing frame 1 respectively. A rotating sleeve 6 is sleeved on the fixing rod 7. A connecting rod 5 is fixedly connected to the rotating sleeve 6. A connecting seat 301 is rotatably connected to one end of the connecting rod 5. The connecting seat 301 is fixedly installed on the extrusion seat 3. A sliding groove 501 is provided through the middle of the connecting rod 5. A guide rod 8 is slidably connected inside the sliding groove 501. The guide rod 8 is fixedly connected to the placement seat 2. A locking mechanism 10 for limiting the extrusion seat 3 is provided inside the fixing frame 1. By lifting the protrusions 201 on both sides, the placement seat 2 moves upward, which in turn lifts the guide rod 8. The upper end of the guide rod 8 is set in the slide groove 501 inside the connecting rod 5. When the guide rod 8 moves upward, it slides inside the slide groove 501, thereby lifting the connecting rod 5. This causes the connecting rod 5 to rotate around the fixed rod 7 via the rotating sleeve 6, converting the rotational motion into the vertical motion of the extrusion seat 3. As a result, the extrusion seat 3 is lifted, and the vertical movement distance of the extrusion seat 3 generated by the rotation process is greater than the movement distance of the guide rod 8, that is, the movement distance of the placement seat 2. The placement seat 2 and the compression seat 3 are separated, making it easier to place the cable 4 on the placement seat 2. After placement, the protrusion 201 is released, and the lower placement seat 2 is driven to move under the combined action of the cable 4's own weight and the spring 202. Through the cooperation of the guide rod 8 and the connecting rod 5, the compression seat 3 is driven to move, so that the compression seat 3 cooperates with the placement seat 2 to initially clamp the placed cable 4. During the clamping process, the greater the downward tension of the cable 4 itself, the greater the clamping force of the compression seat 3 on the upper side of the cable 4, and the greater the gripping force on the cable 4.

[0025] Specifically, in this embodiment, the placement seat 2 is disposed below the compression seat 3, and anti-slip pads 13 are fixedly connected to the ends of both the placement seat 2 and the compression seat 3 near the cable 4. The anti-slip pads 13 increase the friction between the placement seat 2 and the compression seat 3 and the cable 4, thereby further improving the clamping effect on the cable 4.

[0026] Specifically, in this embodiment, the locking mechanism 10 includes a pair of slide rods 1008 fixedly connected to the inner wall of the fixed frame 1. A pair of slide blocks 1007 are slidably connected to the surface of the slide rods 1008. A rack 1005 is fixedly connected to the lower end of the slide block 1007. A pressing block 1006 is fixedly connected to the lower end of the rack 1005. A driving member for driving the rack 1005 to rotate is provided on the upper side of the rack 1005.

[0027] Specifically, in this embodiment, the driving component includes a gear 1004 that meshes with the rack 1005. The gear 1004 is rotatably mounted inside the through groove 102 via a transmission shaft. A worm gear 1003 is fixedly connected to the transmission shaft on one side of the gear 1004. A worm 1001 is meshed on the worm gear 1003. The worm 1001 is rotatably mounted inside the protective shell 9, and the front end of the worm 1001 extends through the protective shell 9 and is fixedly connected to a knob 1002. This device is equipped with a locking mechanism 10. After the locking mechanism 10 is activated, the rack 1005 is moved by the driving component. When the driving component is activated, the knob 1002 is rotated, which in turn drives the worm 1001 to rotate. The worm 1001 then drives the lower worm wheel 1003 to rotate. The rotation of the worm wheel 1003 then drives the left gear 1004 to rotate. The rotation of the gear 1004 then drives the lower rack 1005 to move back and forth. The back and forth movement of the rack 1005 then drives the lower pressing block 1006 to move, so that the lower end of the pressing block 1006 abuts against the pressing seat 3 in the clamp, thereby completing the limiting of the pressing block 1006. Through the self-locking property of the worm wheel 1003 and the worm 1002, the pressing block 1006 is kept stable and does not loosen. This allows the placement seat 2 and the pressing seat 3 to maintain the clamping force for a long time, preventing the cable 4 from being pulled back due to external vibration, thus preventing the cable from falling off. A pair of sliding blocks 1007 are fixedly connected to the upper left side of the rack 1005. A pair of sliding rods 1008 are slidably connected inside the sliding blocks 1007, with both ends of the two sliding rods 1008 fixedly connected to the inner wall of the fixed frame 1. During movement, the rack 1005 drives the two upper sliding blocks 1007 to move together. The sliding blocks 1007 are slidably connected to the sliding rods 1008, thus guiding and limiting the sliding blocks 1007, stabilizing the movement trajectory of the rack 1005, ensuring stable meshing between the rack 1005 and the gear 1004, and consequently ensuring the stability of the lower pressing block 1006. When the knob 1002 is rotated to limit and fix the pressing seat 3, the worm gear 1001 itself has a self-locking capability, ensuring the stability of the locking mechanism 10.

[0028] Specifically, in this embodiment, a positioning rod 12 passes through the knob 1002, and the protective shell 9 has several sets of slots 901 that are adapted to the positioning rod 12. After the locking mechanism 10 completes the fixing of the pressing seat 3, the positioning rod 12 is moved so that one end of the positioning rod 12 is inserted into the slot 901, so that the positioning rod 12 can further fix the knob 1002 and ensure the stability of the locking mechanism 10.

[0029] Specifically, in this embodiment, mounting brackets 11 are fixedly connected to both the front and rear sides of the upper end of the fixing frame 1. The fixing frame can be installed on the iron tower through the mounting brackets 11.

[0030] The working principle of this utility model is as follows: This device is installed on the power tower through the mounting bracket 11. In use, by lifting the protrusions 201 on both sides, the placement seat 2 moves upward. After the placement seat 2 moves upward, the connecting rod 5 is lifted by the guide rod 8, causing the connecting rod 5 to rotate around the fixed rod 7, thereby lifting the compression seat 3, thus separating the placement seat 2 and the compression seat 3, making it convenient to place the cable 4 on the placement seat 2. After placement, the protrusions 201 are released, and under the combined action of the cable 4's own weight and the spring 202, the lower placement seat 2 is driven to move. Through the cooperation of the guide rod 8 and the connecting rod 5, the compression seat 3 is driven to move, so that the compression seat 3 cooperates with the placement seat 2 to initially clamp the placed cable 4. During the clamping process, the greater the downward tension of the cable 4 itself, the greater the clamping force of the compression seat 3 on the upper side of the cable 4, and the greater the gripping force on the cable 4.

[0031] After initial clamping, the locking mechanism 10 is activated, which in turn drives the rack 1005 to move via the drive unit. When the drive unit is activated, the knob 1002 is rotated, which in turn drives the worm 1001 to rotate. The worm 1001 then drives the lower worm wheel 1003 to rotate. The rotation of the worm wheel 1003 then drives the left gear 1004 to rotate. The rotation of the gear 1004 drives the lower rack 1005 to move back and forth. The back and forth movement of the rack 1005 then drives the lower pressing block 1006 to move, so that the lower end of the pressing block 1006 abuts against the pressing seat 3 in the clamping position, thereby completing the limiting and locking of the pressing block 1006. After mechanism 10 limits and fixes the compression seat 3, it simultaneously rotates the positioning rod 12, causing one end of the positioning rod 12 to insert into the slot 901. The positioning rod 12 can fix the knob 1002. Combined with the self-locking ability of the worm gear 1001 and worm wheel 1003, the stability of the locking mechanism 10 is ensured, allowing the placement seat 2 and compression seat 3 to maintain clamping force for a long time, preventing the cable 4 from being pulled back due to external vibration and thus causing it to fall off. At the same time, by moving the positioning rod, one end of the positioning rod 12 is inserted into the slot, allowing the positioning rod to further fix the knob and ensure the stability of the locking mechanism. This device has a simple overall structure, is easy to use, and improves work efficiency.
