Description

Technical Field

[0001] This utility model relates to the field of power equipment, specifically to a complete set of optical cable anti-slip reinforcement and lifting devices. Background Technology

[0002] In recent years, varying degrees of ground wire slippage and clamp misalignment have occurred in icing sections. The significant thickness of the ice layer greatly increases the overall load on the ground wire. Uneven ice thickness distribution on both sides of the tower (both large and small sections) leads to an imbalance in the force on both sides of the fiber optic cable clamps, causing the clamps to slip towards the side with greater tension. When the unbalanced tension generated by the ground wire in adjacent spans exceeds the clamp's gripping force, a sudden slippage and instability at a certain base point can occur, generating a multiplied impact force that can cause slippage of ground wire clamps and misalignment of hardware strings at other tower locations.

[0003] Existing methods rely solely on ground wire lifters to transfer the force on clamps and hardware, combined with chain hoists and cable tensioners for retrieval to repair ground wire slippage and clamp misalignment. However, after the tensioning device regains its load, the clamps tend to slip towards the side with higher tension, failing to fundamentally solve the problem. Therefore, the applicant has developed a complete set of optical cable anti-slip reinforcement and lifting devices to meet current operation and maintenance needs. Utility Model Content

[0004] The present invention aims to provide a complete set of optical cable anti-slip reinforcement and lifting devices, which can increase the height and tension of the optical cable and prevent the suspension clamp from slipping and the hardware string from deviating.

[0005] To solve the above technical problems, the specific solution adopted by this utility model is as follows: a complete set of optical cable anti-slip reinforcement and lifting device, including a reinforcement component and a lifting component. The reinforcement component is a hardware string that can connect the tower and the optical cable. The lifting component includes two vertical branch pipes, an adjusting bolt, a connecting pipe, and a lifting baffle. The connecting pipe is arranged horizontally between the two vertical branch pipes. A threaded through hole is provided in the middle of the connecting pipe. The adjusting bolt passes through the threaded through hole and its lower end is rotatably connected to the lifting baffle. Guide rods are provided on both sides of the adjusting bolt on the lifting baffle. The guide rods pass through the through holes on the connecting pipe. A rotating screw is screwed to the upper end of each vertical branch pipe. A telescopic rod slides through the lower end of the vertical branch pipe. The rotating screw is rotatably connected to the upper end of the telescopic rod. After the lower end of the telescopic rod passes through the vertical branch pipe, a clamp for connecting the optical cable is fixed.

[0006] As a further optimization of the optical cable anti-slip reinforcement and lifting complete set of devices of this utility model: a level is installed on the connecting pipe.

[0007] As a further optimization of the optical cable anti-slip reinforcement and lifting complete set of devices of this utility model: the reinforcement component includes a stainless steel rotating shaft clamp, a wire clamp hanging plate, an annular bolt converter and a connecting hardware string connected in sequence, and one end of the reinforcement component is used to fix the stainless steel rotating shaft clamp to the optical cable.

[0008] As a further optimization of the optical cable anti-slip reinforcement and lifting device of this utility model: a retaining spring is provided at the connection between the stainless steel rotating shaft clamp and the wire clamp hanging plate to prevent the connection from becoming loose.

[0009] As a further optimization of the optical cable anti-slip reinforcement and lifting device of this utility model: the adjusting bolts are screwed with locking nuts on both sides of the connecting pipe.

[0010] As a further optimization of the optical cable anti-slip reinforcement and lifting device of this utility model: the top of the guide rod is provided with a detachable limiting cap.

[0011] As a further optimization of the optical cable anti-slip reinforcement and lifting device of this utility model: the level is fixed in the middle of the outer side wall of the connecting pipe.

[0012] As a further optimization of the optical cable anti-slip reinforcement and lifting device of this utility model: a handle for hand gripping is provided at the upper end of the rotating screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, two vertical branch pipes connected by a connecting pipe are slidably connected at their bottoms to a telescopic rod fixed to the optical cable by a clamp. The lower ends of multiple adjusting bolts threaded through the connecting pipe are connected to a lifting baffle fixed to the crossarm of the tower, so that the optical cables on both sides of the suspension clamp can be raised synchronously to the corresponding height as the adjusting bolts rotate, thereby increasing the tension of the optical cables on both sides of the suspension clamp. This facilitates the installation of reinforcing components between the optical cables on both sides of the suspension clamp and the crossarm of the tower. In addition, a level on the connecting pipe can display the height difference of the optical cables on both sides of the suspension clamp, thereby indirectly displaying the tension of the optical cables on the left and right sides of the suspension clamp. If there is a height difference between the optical cables on both sides, the height of the optical cables on both sides can be adjusted to the same level by rotating the rotating screw to move the vertical branch pipe up or down along the telescopic rod, thereby avoiding the slippage of the suspension clamp due to the different tension of the optical cables on both sides. In addition, the reinforcement components are set on both sides of the tower crossarm and between the optical cable in a triangular and stable structure to prevent the suspension clamp from sliding or swaying. The reinforcement components have a certain initial pre-tightening force when they are installed. When the lifting components are removed, the optical cable moves downward under the action of gravity, which tightens the reinforcement components and increases the tension and pre-tightening force of the suspension clamp.

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts of this utility model that are not described in detail in the following embodiments, such as displaying the height difference of optical cables on both sides by a level, moving the connecting pipe up or down by rotating the adjusting bolt, and moving the vertical branch pipe up or down by rotating the rotating screw, should be known or should be known by those skilled in the art.

[0018] like Figure 1 As shown, a complete set of optical cable anti-slip reinforcement and lifting devices includes a reinforcement component 5 and a lifting component 1. The lifting component 1 can be installed on the optical cables 4 on both sides of the suspension clamp 3, and the height and tension of the optical cables 4 on the left and right sides of the suspension clamp 3 can be increased by the lifting component 1.

[0019] The lifting assembly 1 includes two vertical branch pipes 101, an adjusting bolt 105, a connecting pipe 104, and a lifting baffle 108. The connecting pipe 104 is horizontally positioned between the two vertical branch pipes 101. A threaded through hole is provided in the middle of the connecting pipe 104, through which the adjusting bolt 105 passes. Its lower end is rotatably connected to the lifting baffle 108. Guide rods 1052 are respectively provided on both sides of the adjusting bolt 105 on the lifting baffle 108. The guide rods 1052 pass through the through holes in the connecting pipe 104. The middle part of the guide rod 1052 can slide with the connecting pipe 104, and the lower end of the guide rod 1052 passes through a sliding hole and is fixedly connected to the lifting baffle 108, thereby ensuring that the connecting pipe 104 can move vertically upwards or downwards as the adjusting bolt 105 rotates.

[0020] A rotating screw 106 is screwed to the upper end of each vertical branch pipe 101. A telescopic rod 102 is slidably inserted through the lower end of the vertical branch pipe 101. The rotating screw 106 is rotatably connected to the upper end of the telescopic rod 102. After the lower end of the telescopic rod 102 passes through the vertical branch pipe 101, a clamp 103 for connecting optical cables is fixed thereon.

[0021] Adjusting bolts 105 are fitted with locking nuts 1051 on both sides of the connecting pipe 104. After adjustment, the connecting pipe 104 is clamped by rotating the two locking nuts 1051 to lock its position. Adjusting bolts 105 are extended ring bolts. The upper end of the adjusting bolt 105 is bent to form a ring structure for easy gripping. The lower end of the adjusting bolt 105 passes through a threaded hole and can be rotatably connected to the upper side of the lifting baffle 108. The lower side of the lifting baffle 108 can be secured to the tower crossarm 2. The lifting baffle 108 and the tower crossarm 2 are detachably connected to facilitate removal after the subsequent installation of the reinforcing component 5. Furthermore, a level 107 is fixed in the middle of the connecting pipe 104 to detect the levelness of the connecting pipe 104.

[0022] The reinforcing component 5 is installed between the optical cable 4 and the corresponding tower 2 on both sides of the suspension clamp 3. The reinforcing component 5 includes a stainless steel swivel clamp 504, a clamp hanging plate 503, a ring bolt converter 502, and a connecting hardware string 501 connected in sequence. One end of the reinforcing component 5 is used to fix the stainless steel swivel clamp 504 to the optical cable 4, and the other end is used to fix the connecting hardware string 501 to the tower 2.

[0023] The stainless steel swivel cable clamp 504 is a cable clamp with a wedge-shaped clamp. The stainless steel swivel cable clamp 504 is installed and fixed on the optical cable 4 away from the suspension cable clamp 3. A permanent retaining spring is provided at the connection between the stainless steel swivel cable clamp 504 and the cable clamp hanging plate 503. The permanent retaining spring can lock the stainless steel swivel cable clamp 504 and the cable clamp hanging plate 503, thereby preventing the connection between the stainless steel swivel cable clamp 504 and the cable clamp hanging plate 503 from becoming loose.

[0024] The ring bolt converter 502 consists of a ring bolt and a converter. The ring bolt is connected to the converter, which is in the shape of a double I-beam with I-shaped grooves on the left and right sides and a central hole in the middle. The central hole is connected to the ring bolt, and a nut is installed on the ring bolt to achieve fastening and length adjustment.

[0025] The end of the connecting hardware string 501 that connects to the crossarm 2 of the tower is provided with a through hole. The through hole at the end of the connecting hardware string 501 can correspond to the mounting hole on the crossarm 2 of the tower so that the bolt passes through the aligned through hole and mounting hole to fix the connecting hardware string 501 to the crossarm 2 of the tower.

[0026] A handle 1061 is fixed to the upper end of the rotating screw 106. The handle 1061 is perpendicular to the upper end of the rotating screw 106 so that the rotating screw 106 can be rotated by holding the handle 1061.

[0027] The implementation process of this utility model is as follows: The lifting baffle 108 is secured to the crossarm 2 of the iron tower. Two clamps 103 are fixed to the optical cables 4 on both sides of the suspension clamp 3. The adjusting bolt 105 is rotated, which in turn moves the connecting pipe 104 upwards. The upward movement of the connecting pipe 104 moves the vertical branch pipe 101 upwards, ultimately moving the clamps 103 upwards, thus lifting the optical cable 4. After the upward movement is completed, if the level 107 shows a height difference on both sides, the height of the optical cable 4 is finely adjusted by rotating the rotating screw 106 to move the telescopic rod 102 upwards or downwards. Once the optical cable 4 is level, the two ends of the reinforcing assembly 5 are connected to the iron tower 2 and the optical cable 4 respectively. Finally, the lifting assembly 1 is disassembled. After the lifting assembly is removed, the optical cable moves downwards under gravity, tightening the reinforcing assembly and increasing the tension and preload of the suspension clamp.
