Description

Technical Field

[0001] This utility model belongs to the field of power construction technology, specifically a reinforcement device. Background Technology

[0002] Utility poles are an indispensable part of power construction. Their most basic function is to serve as a support structure for cables, wires, and optical fibers, suspending them in the air to facilitate walking on the ground and avoiding obstacles. They also protect cables, wires, and optical fibers from external damage, and can isolate wires and cables in the air to prevent them from interfering with each other or being grounded. Different wires and cables are isolated from each other by being installed on different utility poles.

[0003] After the utility poles are erected, they need to be fitted with stay cables, which are generally made of steel wire rope. The principle of the stay cables is mainly based on the principle of triangle stability in mechanics. One end of the stay cable is connected to the utility pole, and the other end is inserted into the ground through an anchor rod. The purpose is to ensure the stability and safety of the line, support the pressure resistance of the utility pole and tower, enhance its wind resistance, balance the center of gravity of the utility pole, reduce the risk of overturning, and improve its seismic performance.

[0004] During the installation of the cables, since it is a high-altitude operation, the tensioning structure of the cables needs to be simplified to facilitate the operation of the construction personnel. At the same time, the cables directly connected to the ground have no buffer against impact forces, and once displacement occurs, it cannot be restored. Therefore, improvements need to be made to the existing structure. Utility Model Content

[0005] The purpose of this invention is to provide a reinforcement device in order to solve the above-mentioned problems.

[0006] The technical solution adopted by this utility model is as follows: a reinforcement device, including a base, anchor rods, and a rod body. Anchor rods are embedded around the base, and a rod body is installed in the middle of the base. Positioning boxes are installed around the rod body above the base by reserved bolts. The positioning boxes are equipped with positioning components that can stretch and position the rod body.

[0007] The positioning components include: door panel, connecting seat, cable roller, cable, drive gear, dust cover, passive sector gear, teeth, and damping rod;

[0008] The positioning box has a door panel rotatably installed on the side facing the rod. The bottom two sides of the positioning box are integrated with connecting seats. A cable roller is rotatably connected between the two connecting seats. A drive gear is integrated at the center of the shaft on both sides of the cable roller. A cable is wound on the cable roller. An opening is provided through the top of the positioning box. The cable extends out of the positioning box through the opening. A dust cover is installed between the outer edge of the opening and the cable.

[0009] The positioning box is symmetrically connected to the rear of the inside by a passive sector tooth. The passive sector tooth has teeth evenly distributed on its fan surface. The active gear meshes with the teeth on the passive sector tooth. Each passive sector tooth is rotatably connected to the rear of the positioning box on its upper and lower sides by a damping rod.

[0010] A clamp is installed on the top of the pole, and a connecting lug is integrally provided on the outer wall of the clamp. A spacing adjustment component is provided between the connecting lug and the cable.

[0011] The spacing adjustment assembly includes: an adjustment seat, a screw, a locking bolt, a locking device, and a movable tongue;

[0012] An adjusting seat is movably connected inside the connecting ear. The adjusting seat is connected to a locking device via a screw. A locking bolt is connected to the outside of the screw. A movable tongue is movably connected inside the locking device. The locking device has one large and one small end, and is hollow in the middle. The movable tongue has one large and one small end, and its edge is concave.

[0013] Each screw has three locking bolts.

[0014] The clamps are in two sets, arranged at 90° angles up and down.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the distance between the locking device and the adjusting seat is adjusted by tightening and loosening the locking bolt, and the cable is tightened. At this time, since the forces on the movable tongue and the locking device are in opposite directions, the distance between the movable tongue and the locking device becomes smaller and smaller, and the cable that passes around the movable tongue is clamped. This design can effectively improve the connection strength of the cable, and is convenient to disassemble and assemble, uses less material, and improves the safety of high-altitude operations.

[0017] 2. In this utility model, when an external impact force causes the rod to tilt, the cable in the opposite direction of the tilt will pull the cable roller to rotate. Through the meshing of the teeth, the passive sector teeth will rotate. At this time, the spring outside the damping rod is stressed, pushing the passive sector teeth back to their center position, which in turn connects the cable roller to rotate. The cable pulls the rod back to its position, and the damping rod can reduce the impact force and avoid secondary shaking, thereby achieving the purpose of reinforcing the rod and ensuring the stability of the rod. Compared with the existing connection structure, the buffering performance is better, avoiding one-time damage and improving safety. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In this utility model:

[0027] Reference Figure 1-6 A reinforcement device includes a base 1, anchor rods 101, and rod body 2. Anchor rods 101 are embedded around the base 1, and rod body 2 is installed in the middle of the base 1. Positioning boxes 3 are installed on the base 1 and around the rod body 2 by reserved bolts 102. Positioning boxes 3 are provided with positioning components that can stretch and position the rod body 2 inside.

[0028] The positioning components include: door panel 301, connecting seat 302, cable roller 303, cable 3031, drive gear 3032, dust cover 304, passive sector tooth 4, tooth 401, and damping rod 402;

[0029] The positioning box 3 is rotatably mounted with a door panel 301 on the side facing the rod 2, and a locking pin is installed at the connection between the positioning box 3 and the door panel 301, which can lock the door panel 301. The bottom sides of the positioning box 3 are integrated with a connecting seat 302, and a cable roller 303 is rotatably connected between the two connecting seats 302. The two shaft centers of the cable roller 303 are integrated with a drive gear 3032, and a cable 3031 is wound on the cable roller 303.

[0030] A passive sector tooth 4 is symmetrically rotatably connected to the rear of the positioning box 3. The passive sector tooth 4 has teeth 401 evenly distributed on its fan-shaped surface. A damping rod 402 is rotatably connected to the upper and lower sides of each passive sector tooth 4 and the rear of the positioning box 3. The driving gear 3032 meshes with the teeth 401 on the passive sector tooth 4. A spring attached to the damping rod 402 keeps the passive sector tooth 4 in a centered position. At this point, the meshing between the driving gear 3032 and the teeth 401 on the passive sector tooth 4 ensures the cable winding roller 30... 3. It will not rotate arbitrarily; when an external impact force causes the rod 2 to tilt, the cable 3031, which is in the opposite direction of the tilt, will pull the cable roller 303 to rotate. Through the meshing of the teeth, the passive sector tooth 4 will rotate. At this time, the spring outside the damping rod 402 is stressed, pushing the passive sector tooth 4 back to its center position, which in turn causes the cable roller 303 to rotate. The cable 3031 pulls the rod 2 back to its center position, while the damping rod 402 can reduce the impact force and avoid secondary shaking, thereby achieving the purpose of reinforcing the rod 2 and ensuring the stability of the rod 2.

[0031] Furthermore, an opening is provided through the top of the positioning box 3, through which the pull cable 3031 extends out of the positioning box 3. A dust cover 304 is installed between the outer edge of the opening and the pull cable 3031. The dust cover 304 serves to prevent dust from entering the interior of the positioning box 3 through the opening. The dust cover 304 is made of rubber and has the flexibility to move with the pull cable 3031.

[0032] Furthermore, a clamp 201 is installed on the top of the pole 2. The outer wall of the clamp 201 is integrally provided with a connecting ear 2011. A spacing adjustment component is provided between the connecting ear 2011 and the cable 3031. There are two sets of clamps 201, which are staggered at 90° to each other, so that the pole 2 can be reinforced from four directions, thereby improving the stability of the pole 2.

[0033] Furthermore, the spacing adjustment assembly includes: an adjustment seat 202, a screw 2021, a locking bolt 2022, a locking device 203, and a movable tongue 2031;

[0034] An adjusting seat 202 is movably connected inside the connecting ear 2011. The adjusting seat 202 is connected to a locking device 203 via a screw 2021. A locking bolt 2022 is externally connected to the screw 2021. A movable tongue 2031 is movably connected inside the locking device 203. The locking device 203 has one large and one small end, and is hollow in the middle. The movable tongue 2031 also has one large and one small end, and its edge is concave. The locking device 2031 is controlled by tightening or loosening the locking bolt 2022. 22. Adjust the distance between the locking device 203 and the adjusting seat 202 to tighten the cable 3031. At this time, since the forces on the movable tongue 2031 and the locking device 203 are in opposite directions, the distance between the movable tongue 2031 and the locking device 203 becomes smaller and smaller, clamping the cable 3031 that passes around the movable tongue 2031. This design can effectively improve the connection strength of the cable 3031, and is easy to disassemble and assemble, uses less consumables, and improves the safety of high-altitude operations.

[0035] Furthermore, each screw 2021 has three locking bolts 2022. By using the combination of locking bolts 2022, the distance between the locking device 203 and the adjusting seat 202 can be adjusted, the cable 3031 can be tightened, and the purpose of reinforcing the locking device 203 and the adjusting seat 202 can be achieved to prevent the bolts from loosening.

[0036] Furthermore, the outer wall of the damping rod 402 and the outer wall of the movable rod are equipped with springs to form a spring-and-cylinder integrated shock absorber. When the passive sector tooth 4 rotates, the spring outside the damping rod 402 is stressed, pushing the passive sector tooth 4 back to its center position. The damping rod 402 can reduce the impact force and avoid secondary shaking, thus achieving the purpose of reinforcing the rod 2.

[0037] Working principle: First, assemble the rod body 2 and install two clamps 201 on the outside of the rod body 2, ensuring that the two clamps 201 are staggered vertically at 90°. Then, pull out the cables 3031 on the four cable winding rollers 303, passing the end of the cable 3031 through the gap between the movable tongue 2031 and the locking device 203, wrapping it around the movable tongue 2031 once, and pulling the end out. Finally, lock the end of the cable 3031 using the cable lock. Since both the movable tongue 2031 and the locking device 203 are set with one end larger than the other, adjust the distance between the locking device 203 and the adjusting seat 202 by tightening and loosening the locking bolt 2022, thus tightening the cable 3031. At this point, because the forces on the movable tongue 2031 and the locking device 203 are in opposite directions, the gap between the movable tongue 2031 and the locking device 203 becomes smaller and smaller, thus tightening the cable 3031 that has passed around the movable tongue 2031. 31. Clamping is performed. This design effectively improves the connection strength of the cable 3031, and is easy to assemble and disassemble, requiring less material. Finally, the spring on the outside of the damping rod 402 keeps the passive sector tooth 4 in a centered position. At this time, the meshing between the active gear 3032 and the teeth 401 on the passive sector tooth 4 ensures that the cable winding roller 303 will not rotate arbitrarily. When the external impact force causes the rod 2 to tilt, the cable 3031, which is tilted in the opposite direction, will pull the cable winding roller 303 to rotate. Through the meshing of the teeth, the passive sector tooth 4 rotates. At this time, the spring on the outside of the damping rod 402 is stressed, pushing the passive sector tooth 4 back to its centered position, thereby connecting the cable winding roller 303 to rotate. The cable 3031 pulls the rod 2 back to its position, while the damping rod 402 can reduce the impact force and avoid secondary shaking, thus achieving the purpose of reinforcing the rod 2 and ensuring the stability of the rod 2.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
