Description

Technical Field

[0001] This invention relates to the field of tension clamps, and more specifically, to a conical locking tension clamp that is easy to maintain. Background Technology

[0002] Tension clamps are hardware used to secure conductors, withstand conductor tension, and attach them to tension strings or towers. Based on their structure and installation conditions, tension clamps can be broadly classified into two categories. The first category consists of clamps that must withstand the full tension of the conductor or lightning protection wire, with a clamping force not less than 90% of the rated tensile strength of the installed conductor or lightning protection wire, but which do not act as conductors. These clamps can be removed and reused after conductor installation. Types of clamps include bolt-type and wedge-type tension clamps.

[0003] Bolt-type tension clamps use multiple U-shaped clamps and bolts to fasten cables. This method requires multiple U-shaped clamps and bolts, and the clamps and bolts are separate parts, so they need to be removed one by one during assembly, which is cumbersome. Smaller bolts are also easy to lose when separated from the U-shaped clamps. Disassembly is also cumbersome. Therefore, a tapered locking tension clamp that is easy to maintain is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a conical locking tension clamp that is easy to maintain. By setting up a drive unit and a locking unit, it solves the problem that the components are relatively scattered and inconvenient to disassemble and assemble when using conventional fastening.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A conical locking tension clamp that is easy to maintain includes a tension frame body, one end of which is connected to an arc-shaped guide frame body. Slide grooves and positioning grooves are provided on both sides of the tension frame body. A drive unit is assembled on the tension frame body through the slide grooves, and a locking unit is assembled on the tension frame body through the positioning grooves.

[0007] The drive unit is connected to a tensioning unit for connection with the locking unit. Under the action of the tensioning unit, the drive unit can move toward the locking unit, so that the locking unit locks the cable.

[0008] The locking unit includes locking arms that are hinged to each other. Each of the two locking arms has an extension portion fixed on one side. An inclined contact portion is formed at the end of the extension portion. A tapered locking portion is fixed at the bottom of the inclined contact portion. An clearance gap is formed between the two extension portions. A locking buckle that matches the positioning groove is fixed on the inner side of the locking arm.

[0009] As a preferred technical solution of this application, one end of the locking arm is formed with a tensioning part, one side of the tensioning part is formed with a tensioning groove, and a tensioning cavity is formed between the two tensioning grooves.

[0010] As a preferred technical solution of this application, the driving unit includes driving arms that are hinged to each other, and each of the two driving arms has a slider on its inner side. The slider is adapted to the slide groove, and a connecting part is formed at one end of the driving arm.

[0011] One side of the drive arm is connected to an abutment block facing the inclined abutment portion, and an arc-shaped abutment protrusion is formed at the end of the abutment block.

[0012] As a preferred technical solution of this application, the tensioning unit includes an L-shaped connecting seat and an arc-shaped column connected to one side of the L-shaped connecting seat. The L-shaped connecting seat is hinged to the outside of the connecting part. The surfaces of the two arc-shaped columns are threaded together with a tensioning ring. A positioning block is movably connected to one side of the tensioning ring. The positioning block is adapted to the tensioning cavity.

[0013] As a preferred technical solution of this application, the number of the sliding groove and the positioning groove is four, and the two sliding grooves and the two positioning grooves are divided into two groups.

[0014] As a preferred technical solution of this application, a quick-locking component is connected between the two tensioning units in the two groups;

[0015] The quick-locking component includes a hexagonal rotating rod and a rotating block fixed to the surface of the hexagonal rotating rod. Both ends of the hexagonal rotating rod are slidably fitted with rotating cylinders, and the rotating cylinders have an inner cavity adapted to the arc-shaped column.

[0016] As a preferred technical solution of this application, the surface of the tensioning ring has anti-slip ridges, and the rotating cylinder is also provided with a positioning cavity that is adapted to the tensioning ring and the anti-slip ridges, and the positioning cavity is connected to the inner cavity.

[0017] As a preferred technical solution of this application, a sliding cavity is provided inside the rotating cylinder, the end of the hexagonal rotating rod slides in the sliding cavity, and the end of the hexagonal rotating rod is connected to a spring connected to the side wall of the sliding cavity.

[0018] As a preferred technical solution of this application, both the tension frame and the arc-shaped guide frame have locking grooves inside for cable discharge.

[0019] As a preferred technical solution of this application, a connecting pin is movably inserted into the top of the arc-shaped guide frame, and the end of the connecting pin has a positioning pin.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the scheme of this application:

[0022] By coordinating the drive unit and locking unit, after the drive arm and locking arm are fastened to the tension frame, the tensioning unit can be flipped to connect with the locking unit on one side, thus quickly assembling the drive unit and locking unit. Further rotation of the tensioning ring inside the tensioning unit can rotate the conical locking part to achieve a contact and fastening effect on the cable. In this way, there is no need to remove multiple bolts one by one and rotate and tighten them sequentially during the entire installation process, which improves assembly efficiency and facilitates subsequent disassembly and maintenance.

[0023] At the same time, all the components are connected, which makes it less likely for smaller parts to be lost, and facilitates transportation, handling and assembly.

[0024] 2. By using a quick-locking mechanism, the rotation of a single hexagonal rotating rod can simultaneously drive the rotation of multiple conical locking parts, causing them to simultaneously contact the surface of the cable to form a contact and fastening effect, thereby further improving the cable fixing efficiency. At the same time, the rotation direction between the two conical locking parts is designed to be opposite, so while achieving dual-point pressing and fastening, it can also better achieve the anti-slip effect of the cable after fastening.

These terms are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] Please see Figures 1 to 8 The present invention provides a technical solution: a conical locking tension clamp that is easy to maintain, including a tension frame 1, one end of which is connected to an arc-shaped guide frame 2. Sliding grooves 11 and positioning grooves 12 are provided on both sides of the tension frame 1. A drive unit 3 is assembled on the tension frame 1 through the sliding groove 11, and a locking unit 4 is assembled on the tension frame 1 through the positioning groove 12.

[0050] The drive unit 3 is connected to a tensioning unit 5 for connection with the locking unit 4. Under the action of the tensioning unit 5, the drive unit 3 can move toward the locking unit 4, so that the locking unit 4 locks the cable.

[0051] The locking unit 4 includes locking arms 41 that are hinged together. The two locking arms 41 can be flipped relative to each other without separating, which facilitates the assembly and application of the locking unit 4 on the tension frame 1 and makes it easy to handle. Each of the two locking arms 41 has an extension part 42 fixed on one side. An inclined abutment part 43 is formed at the end of the extension part 42. A conical locking part 47 is fixed at the bottom of the inclined abutment part 43. The conical locking part 47 has an arc-shaped design, which can form a larger contact with the surface of the cable when it is flipped to a certain angle. The contact between the surfaces can compress the cable and achieve a positioning effect. A clearance gap 44 is formed between the two leads 42. The clearance gap 44 is designed so that there is no movement obstruction when the two locking arms 41 are flipped. A locking buckle 410 that matches the positioning groove 12 is fixed on the inner side of the locking arm 41. After the locking buckle 410 is inserted into the corresponding positioning groove 12, it can form a positioning effect on the locking unit 4, so that it cannot slide in the length direction of the tension frame 1, which facilitates the subsequent fastening operation.

[0052] like Figure 5 As shown, a tensioning part 45 is formed at one end of the locking arm 41, a tensioning groove 46 is formed on one side of the tensioning part 45, and a tensioning cavity is formed between the two tensioning grooves 46.

[0053] The drive unit 3 includes drive arms 31 that are hinged to each other. Each drive arm 31 has a slider 32 on its inner side. The slider 32 is adapted to the slide groove 11. One end of the drive arm 31 has a connecting part 33. After the slider 32 on the extended drive arm 31 is placed into the corresponding slide groove 11, the drive unit 3 can slide along the length direction of the tension frame 1, thereby adjusting the distance between it and the locking unit 4, and realizing the abutment of the conical locking part 47.

[0054] Among them, one side of the drive arm 31 is connected to an abutment block 34 in the direction of the inclined abutment portion 43, and an arc-shaped abutment protrusion 35 is formed at the end of the abutment block 34;

[0055] The tensioning unit 5 includes an L-shaped connecting seat 51 and an arc-shaped column 52 connected to one side of the L-shaped connecting seat 51. Two adjacent arc-shaped columns 52 can be spliced ​​to form a cylinder, and each has a corresponding threaded groove. The L-shaped connecting seat 51 is hinged to the outside of the connecting part 33. The surfaces of the two arc-shaped columns 52 are threadedly connected to a tensioning ring 53. Rotating the tensioning ring 53 allows it to move on the surfaces of the two arc-shaped columns 52 to achieve threaded engagement. A positioning block 54 is movably connected to one side of the tensioning ring 53, and the positioning block 54 is adapted to the tensioning cavity.

[0056] The number of the slide groove 11 and the positioning groove 12 are both four, and two slide grooves 11 and two positioning grooves 12 form a group, which is divided into two groups;

[0057] A quick-locking element 6 is connected between the two tensioning units 5 in the two groups;

[0058] The quick-locking component 6 includes a hexagonal rotating rod 61 and a rotating block 62 fixed to the surface of the hexagonal rotating rod 61. Both ends of the hexagonal rotating rod 61 are slidably fitted with rotating cylinders 63. The rotating cylinder 63 has an inner cavity 64 that is adapted to the arc-shaped column 52. The inner cavity 64 can avoid the arc-shaped column 52 when the tensioning ring 53 is tightened.

[0059] The surface of the tension ring 53 has anti-slip ridges 530, and the rotating cylinder 63 is also provided with a positioning cavity 65 that is adapted to the tension ring 53 and the anti-slip ridges 530. The positioning cavity 65 is connected to the inner cavity 64. When the tension ring 53 is tightened, the positioning cavity 65 can accommodate the tension ring 53 and the anti-slip ridges 530.

[0060] The rotating cylinder 63 has a sliding cavity 630. The end of the hexagonal rotating rod 61 slides in the sliding cavity 630. The end of the hexagonal rotating rod 61 is connected to a spring 631 that is connected to the side wall of the sliding cavity 630. By the force of the spring 631, the rotating cylinder 63 can be unfolded outward in the natural state. In this way, when the two rotating cylinders 63 are engaged with the surface of the corresponding tension ring 53, the rotating cylinders 63 can maintain a relatively stable engagement state between the tension rings 53, thereby ensuring stability in the rotation state.

[0061] Both the tension frame 1 and the arc-shaped guide frame 2 have locking grooves inside for cable discharge;

[0062] A connecting pin 21 is movably inserted into the top of the arc-shaped guide frame 2, and the end of the connecting pin 21 has a positioning pin;

[0063] like Figure 6 As shown, when it is necessary to fix the cable, the cable is first inserted into the corresponding tension frame 1 and arc-shaped guide frame 2. Then, the unfolded drive unit 3 and locking unit 4 are fastened to the surface of the tension frame 1. Specifically, the slider 32 on the unfolded drive unit 3 is aligned with the corresponding slide groove 11, and then the unfolded drive unit 3 is closed. In this way, the slider 32 will be placed in the slide groove 11 and can slide along the length direction of the slide groove 11. Similarly, the unfolded locking unit 4 is closed at the position corresponding to the positioning groove 12, so that the locking buckle 410 in the locking unit 4 is engaged in the corresponding positioning groove 12. This completes the assembly of the drive unit 3 and the locking unit 4.

[0064] In the above application, since the multiple components on the drive unit 3 and the locking unit 4 are connected, there is no need to pick them up one by one, and there is no need to worry about the components being easily lost. Compared with the conventional method of picking up the U-shaped clamps and bolts one by one, the assembly efficiency is effectively improved.

[0065] Flip the quick-locking member 6 so that the tensioning ring 53 on it flips to one side of the tensioning groove 46. Then rotate the tensioning ring 53 so that the positioning block 54 on it can be engaged in the corresponding tensioning groove 46. When the tensioning ring 53 is rotated further, the drive unit 3 can slide towards the locking unit 4, thereby promoting the locking unit 4 to form a contact lock on the cable. At the same time, during this process, the positioning block 54 will form an effective contact state with the tensioning groove 46, thereby keeping the tensioning unit 5 in a horizontal state and completing the connection between the drive unit 3 and the locking unit 4.

[0066] As the tension ring 53 rotates continuously, the drive unit 3 moves toward the locking unit 4. The arc-shaped abutment protrusion 35 on the drive unit 3 abuts against the surface of the inclined abutment part 43. The inclined abutment part 43, which is subjected to the abutment, can rotate toward the direction of the cable, and finally the conical locking part 47 abuts against the surface of the cable. This can form a locking effect on the cable, so that it is not necessary to rotate and tighten multiple bolts one by one, which simplifies the assembly process and facilitates quick disassembly during subsequent maintenance.

[0067] like Figure 1 The above describes the state after the cable has been tightened, and the Figure 1 The drive unit 3 and locking unit 4 shown are multiple, thus forming a multi-point positioning effect on the cable surface, further improving the positioning effect of the cable. This embodiment provides an example of dual-point positioning, as detailed below. Figure 3 As shown;

[0068] After the drive unit 3 and locking unit 4 on both sides are assembled, and the tensioning unit 5 is flipped to the horizontal position, the rotating cylinders 63 at both ends of the quick-locking component 6 can be fitted onto the surface of the corresponding tensioning ring 53. This allows the rotating block 62 to be rotated directly. The hexagonal rotating rod 61 can then act directly on the surface of the rotating cylinders 63 at both ends to achieve synchronous drive of the two tensioning rings 53. Ultimately, the two locking units 4 can lock the cable synchronously, further improving the cable fixing efficiency.

[0069] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
