Description

Technical Field

[0001] This invention relates to the field of pre-twisted wire installation tools, specifically a pre-twisted wire auxiliary installation tool. Background Technology

[0002] Pre-twisted wire is generally made of aluminum-magnesium alloy or steel-cored aluminum stranded wire. It is a high-strength ductile material, consisting of several single-strand spiral metal wires pre-twisted. Based on the conductor cross-section, the spiral metal wires with a specified inner diameter are rotated in the spiral direction to form a tubular cavity. The pre-twisted wire extends spirally around the conductor, and under the tension of the conductor, it rotates spirally, creating an anchoring force for the conductor. Currently, in power transmission line construction and technical renovation projects, the installation of pre-twisted wire on cables mainly relies on flathead screwdrivers and pliers, combined with manual labor, resulting in low installation efficiency and high labor intensity. To address these issues, Chinese invention patent application (publication number: CN 111941357A, publication date: November 17, 2020) discloses a device for installing and removing pre-twisted wire protective cables. In this design, the toothed disc has several notches and slots on the side away from the fixed seat to accommodate pre-twisted wires. The handle is located on the side of the fixed seat opposite to the toothed disc. After the two fixed seats are connected by a connector, a circular hole for the wire to pass through is formed between the two toothed discs, and several notches and slots surround the edge of the circular hole. The notches and slots on the toothed disc ensure that the pre-twisted wires are well fixed. The two fixed seats can be easily and quickly separated and connected by the connector. The wire protection line can be quickly installed or removed by rotating the handle, without the need for individual operation of each pre-twisted wire. This improves work efficiency and construction quality, reduces labor intensity, and the device is simple in structure, lightweight, and easy to carry.

[0003] This solution reduces the difficulty and labor intensity of pre-twisted wire winding to some extent. However, during use, the device still requires additional tools to fix the ends of the pre-twisted wire to the cable before winding can begin. Furthermore, because the tool has a cable running through it, the operator can only rotate it once at a time, meaning only one turn of pre-twisted wire can be wound per operation. This requires frequent rotation of the tool to complete the winding of all the pre-twisted wire, making operation and installation inconvenient and the installation efficiency of the pre-twisted wire not high enough. Summary of the Invention

[0004] The purpose of this invention is to provide a pre-twisted wire auxiliary installation tool to solve the problems mentioned in the background art.

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

The winding seat ring is rotatably mounted on the end face of the winding frame base. At least one pair of clamping assemblies for clamping the pre-twisted wire are mounted on the winding seat ring. The winding seat ring is driven and connected to the rack assembly via a transmission mechanism. To facilitate the installation of the auxiliary installation tool kit of this invention onto the cable, mounting notches are obviously provided on the positioning seat ring, locking seat ring, and winding seat ring.

[0011] As a further embodiment of the present invention, the rack assembly includes multiple racks sequentially spliced ​​together. One end of each rack has a mounting groove, and the other end has a mounting strip for engaging with the mounting groove. Adjacent racks are spliced ​​together through the engagement of the mounting groove and the mounting strip. The rack assembly adopts a modular design, allowing operators to assemble and connect an appropriate number of racks according to the actual required length of pre-twisted wire for the cable, thus enabling operation and use, and providing good applicability.

[0012] As a further embodiment of the present invention, the rack end is provided with a pair of pin holes that extend vertically through each other, and a limit pin is inserted into the pin holes.

[0013] As a further embodiment of the present invention, the positioning and clamping mechanism includes a positioning clamping block that slides on the end face of the positioning seat ring and a positioning threaded rod that passes through the circumferential side wall of the positioning seat ring through a threaded engagement. The inner end of the positioning threaded rod is rotatably connected to the positioning clamping block, and the outer end of the positioning threaded rod has a positioning adjustment knob.

[0014] As a further embodiment of the present invention, the locking clamping mechanism includes a locking block that slides on the end face of the locking seat ring and a locking threaded rod that passes through the circumferential side wall of the locking seat ring through a threaded engagement. The inner end of the locking threaded rod is rotatably connected to the locking block, and the outer end of the locking threaded rod has a locking adjustment knob.

[0015] As a further embodiment of the present invention, a sliding sleeve for sliding engagement with a rack is fixedly connected to the bottom end of the winding machine frame, and a bottom gear frame is fixedly connected to the outside of the sliding sleeve, and a bottom gear for meshing with the rack is rotatably mounted on the gear frame.

[0016] As a further embodiment of the present invention, the transmission mechanism includes a vertical rotating shaft, a top helical gear, a wing plate rotating shaft, a wing plate helical gear, a wing plate gear, and a driven gear ring. The two sides of the winding machine frame are integrally connected to the base wing plate. The wing plate rotating shaft is rotatably mounted on the base wing plate. One end of the wing plate rotating shaft is fixedly fitted with the wing plate helical gear, and the other end of the wing plate rotating shaft is fixedly fitted with the wing plate gear.

[0017] The driven gear ring is fixedly installed on the end face of the winding seat ring, and the driven gear ring is meshed with the wing plate gear;

[0018] The bottom end of the vertical rotating shaft is fixedly connected to the central shaft of the bottom gear, and the top end of the vertical rotating shaft is fitted with a top helical gear, which meshes with the wing plate helical gear.

[0022] 2. The pre-twisted wire positioning device has a reasonable structural design. By adjusting the corresponding positioning threaded rod, the movement of the positioning clamp can be controlled. One of the positioning clamps can press the end of the pre-twisted wire onto the cable, while the other positioning clamps can directly press onto the cable. With the locking clamping mechanism, the entire auxiliary installation tool is locked to prevent the entire auxiliary installation tool from rotating relative to the cable during use. The positioning seat ring of the pre-twisted wire positioning device can also be angled to facilitate winding the pre-twisted wire.

[0023] 3. The pre-twisted wire auxiliary installation tool of the present invention does not require a power source, has a relatively low overall weight, and is easy to carry and use.

[0024] The present invention has a reasonable structural design. In actual use, the winding machine frame can be pushed in one direction. During the pushing process, the rack assembly and transmission mechanism can drive the pre-twisted wire to be wound on the cable. The operation is more convenient and does not require the operator to rotate the wire frequently, which helps to improve the installation efficiency of the pre-twisted wire.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figures 1-15 A pre-twisted wire auxiliary installation tool includes a pre-twisted wire positioning device 100, a pre-twisted wire winding device 200, a tool locking device 300, and a pair of rack and pinion assemblies 400;

[0043] The pre-twisted wire positioning device 100 includes a positioning frame base 1 and a positioning ring 2. The positioning ring 2 can be rotatably mounted on the end face of the positioning frame base 1 via a slewing bearing 11. Multiple positioning clamping mechanisms 3 for clamping the ends of the pre-twisted wire and the cable 600 are distributed and installed on the positioning ring 2. In this embodiment, the positioning frame base 1 can specifically adopt a U-shaped frame.

[0044] The tool locking device 300 includes a locking frame base 4 and a locking ring 5. The locking ring 5 is fixedly installed on the end face of the locking frame base 4, and multiple locking clamping mechanisms 7 for clamping the cable 600 are distributed and installed on the locking ring 5. In this embodiment, the locking frame base 4 can also be a U-shaped frame.

[0045] One end of the rack assembly 400 is inserted and fixed to the positioning frame base 1, and the other end of the rack assembly 400 is inserted and fixed to the locking frame base 4;

[0046] The pre-twisted wire winding device 200 includes a winding seat ring 8 and a winding machine frame seat 6 whose bottom end is slidably engaged with the rack assembly 400. In this embodiment, the winding machine frame seat 6 can also be a U-shaped frame. The winding seat ring 8 is rotatably engaged on the end face of the winding machine frame seat 6. At least one pair of clamping assemblies for clamping the pre-twisted wire are installed on the winding seat ring 8. The winding seat ring 8 is drivenly connected to the rack assembly 400 through a transmission mechanism.

[0047] To facilitate the mounting of the auxiliary installation tool kit of this invention onto the cable 600, mounting notches 500 are obviously provided on the positioning ring 2, the slewing bearing 11, the locking ring 5, and the winding ring 8. The size of the mounting notches 500 is relatively small and does not affect the free rotation of the positioning ring 2, the slewing bearing 11, and the winding ring 8. To facilitate the operator in pushing the winding machine frame 6, a push handle 61 can also be fixedly installed on the winding machine frame 6.

[0048] During the installation of the pre-twisted wire, the end of the pre-twisted wire is pressed and fixed onto the cable 600 by the positioning clamping mechanism 3 of the pre-twisted wire positioning device 100. The cable 600 is clamped by the locking clamping mechanism 7 of the tool locking device 300 to prevent the entire auxiliary installation tool from rotating relative to the cable 600 during use. The pre-twisted wire is clamped by the clamping assembly. The clamping assembly has a large clamping gap, which only serves as a limit. The clamping creates a hole to ensure that the pre-twisted wire can pass through smoothly. When the operator pushes the winding machine frame 6, the pre-twisted wire can slide relative to the clamping assembly. The above steps are repeated. After the first step is completed, the operator only needs to push the winding machine frame 6 along the extension direction of the cable 600. The winding machine frame 6 moves away from the pre-twisted wire positioning device 100. During the movement, since the winding seat ring 8 is driven and connected to the rack assembly 400 through the transmission mechanism, the transmission mechanism will drive the winding seat ring 8 and the clamp assembly to rotate under the action of the rack assembly 400. Every time the winding machine frame 6 moves a certain distance, the clamp assembly on the winding seat ring 8 will pull the pre-twisted wire to wind around the cable 600 once, until all the pre-twisted wire is wound to the tool locking device 300.

[0049] The present invention has a reasonable structural design. In actual use, the winding machine frame 6 can be pushed in one direction. During the pushing process, the pre-twisted wire can be driven to wind around the cable with the cooperation of the rack assembly 400 and the transmission mechanism. The operation is more convenient and does not require the operator to rotate the wire frequently, which helps to improve the installation efficiency of the pre-twisted wire.

[0050] Please see Figures 13-15 As a specific solution, the rack assembly 400 includes a plurality of racks 9 spliced ​​together in sequence. One end of the rack 9 has an insert groove 91, and the other end of the rack 9 has an insert strip 92 for cooperating with the insert groove 91. Adjacent racks 9 are spliced ​​together by the cooperation between the insert groove 91 and the insert strip 92.

[0051] The rack and pinion assembly 400 adopts a modular design. Workers can assemble and connect an appropriate number of racks 9 according to the actual length of the pre-twisted wire required for the cable, and then operate it. It has good applicability.

[0052] The rack 9 has a pair of through-hole pin holes at its end, with limiting pins 93 inserted into each hole. These limiting pins 93 secure the rack 9 to the insertion holes in the positioning frame 1 and locking frame 4. During assembly with the positioning frame 1, the rack 9 is inserted into the insertion holes, with one pin hole located at the front and the other at the rear. The limiting pins 93 are simultaneously inserted into both holes, locking the positioning frame 1 and the rack 9. Similarly, the locking frame 4 is fixed to the rack 9 using the same method.

[0053] In this embodiment, please refer to Figures 4-6 The positioning clamping mechanism 3 includes a positioning clamping block 31 that slides on the end face of the positioning seat ring 2 and a positioning threaded rod 32 that passes through the circumferential side wall of the positioning seat ring 2 through a threaded engagement. The inner end of the positioning threaded rod 32 is rotatably connected to the positioning clamping block 31, and the outer end of the positioning threaded rod 32 has a positioning adjustment knob.

[0054] The working principle of the positioning clamping mechanism 3 is as follows: by rotating the positioning threaded rod 32, the positioning threaded rod 32 can push the positioning clamping block 31 to move towards the cable 600. The positioning clamping block 31 can press the end of the pre-twisted wire onto the cable 600, thereby achieving the pressing and positioning of the end of the pre-twisted wire and the cable 600.

[0055] In this embodiment, please refer to Figures 7-9The locking clamping mechanism 7 includes a locking clamping block 71 that slides on the end face of the locking seat ring 5 and a locking threaded rod 72 that passes through the circumferential side wall of the locking seat ring 5 through a threaded engagement. The inner end of the locking threaded rod 72 is rotatably connected to the locking clamping block 71, and the outer end of the locking threaded rod 72 has a locking adjustment knob.

[0056] The working principle of the locking clamping mechanism 7 is as follows: by rotating the locking threaded rod 72, the locking threaded rod 72 can push the locking clamp 71 to move towards the cable 600. By using multiple locking clamps 71, the cable 600 can be clamped, thereby completing the locking of the entire auxiliary installation tool and preventing the entire auxiliary installation tool from rotating relative to the cable 600 during use.

[0057] In this embodiment, please refer to Figures 10-12 and Figure 15 The bottom end of the winding machine frame 6 is fixedly connected to a sliding sleeve 62 for sliding engagement with the rack 9. A bottom gear frame 621 is fixedly connected to the outside of the sliding sleeve 62. A bottom gear 632 for meshing with the rack 9 is rotatably mounted on the gear frame 621.

[0058] The transmission mechanism includes a vertical rotating shaft 63, a top helical gear 631, a wing plate rotating shaft 641, a wing plate helical gear 642, a wing plate gear 643, and a driven gear ring 81. The winding machine frame base 6 is integrally connected to two base wing plates 64 on both sides. A wing plate rotating shaft 641 is rotatably mounted on the base wing plate 64. A wing plate helical gear 642 is fixedly fitted at one end of the wing plate rotating shaft 641, and a wing plate gear 643 is fixedly fitted at the other end. The driven gear ring 81 is fixedly mounted on the end face of the winding seat ring 8 and meshes with the wing plate gear 643. The bottom end of the vertical rotating shaft 63 is fixedly connected to the central axis of the bottom gear 632, and the top end of the vertical rotating shaft 63 is fixedly fitted with the top helical gear 631, which meshes with the wing plate helical gear 642. In this embodiment, the driven gear ring 81 is rotatably connected to the end face of the winding machine frame base 6 via a slewing bearing 65. Clearly, the driven gear ring 81 and the slewing bearing 65 also have mounting notches 500.

[0059] The working principle of the transmission mechanism is as follows: When the operator pushes the winding machine frame 6 along the extension direction of the cable 600, the winding machine frame 6 moves away from the pre-twisted wire positioning device 100. The gear frame 621 will slide relative to the rack 9. Under the action of the rack 9, the bottom gear 632 meshing with it will rotate. The rotating bottom gear 632 will sequentially drive the vertical rotating shaft 63, the top helical gear 631, the wing plate helical gear 642, the wing plate rotating shaft 641, the wing plate gear 643, and the driven gear ring 81 to rotate. The driven gear ring 81 drives the winding seat ring 8 and the clamp assembly to rotate. The clamp assembly will then pull the pre-twisted wire to wind on the cable 600.

[0060] For specific solutions, please refer to Figure 12 The clamping assembly includes a telescopic rod 83 and a clamping block 84. A seat plate 82 is integrally connected to both sides of the winding seat ring 8. The telescopic rod 83 is fixedly mounted on the seat plate 82, and a clamping block 84 for clamping the pre-twisted wire is fixedly mounted on the telescopic end of the telescopic rod 83. The telescopic rod 83 can adopt a structure from the prior art, and the end of the telescopic rod 83 also has a locking nut 831 for locking the telescopic end.

[0061] The working principle of the clamp assembly is as follows: When it is necessary to clamp the pre-twisted wire, rotate the locking nut 831 in the forward direction to release the lock of the telescopic end, adjust the extension of the telescopic rod 83 to drive the clamping blocks 84 to move towards each other, and the two clamping blocks 84 can limit and clamp the pre-twisted wire. Then, rotate the locking nut 831 in the reverse direction to lock the telescopic end. The clamping force applied by the telescopic rod 83 is relatively small, and the pre-twisted wire can slide relative to the two clamping blocks 84 so that the pre-twisted wire can be wound on the cable 600.

[0062] The working principle of this invention is:

[0063] Step S1: The worker carries the auxiliary installation tool of the present invention to the designated position of the cable 600, aligns the installation notch 500 of the auxiliary installation tool with the cable 600, and passes the installation notch 500 through the cable 600 from top to bottom. The positioning threaded rod 32 of the pre-twisted wire positioning device 100 is rotated, and the positioning clamp 31 is pressed onto the cable 600. Then, the locking threaded rod 72 is rotated, and the cable 600 is clamped by multiple locking clamps 71, thereby completing the locking of the entire auxiliary installation tool.

[0064] Step S2: Take out the first pre-twisted wire and fix the end of the pre-twisted wire under the positioning clamping block 31 of one of the positioning clamping mechanisms 3. The positioning clamping block 31 presses the end of the pre-twisted wire onto the cable 600. Then, pass the pre-twisted wire through the pre-twisted wire winding device 200 and use the clamping block 84 of the clamping assembly to clamp the pre-twisted wire.

[0065] Step S3: The operator pushes the handle 61 of the pre-twisted wire winding device 200, causing the winding machine frame 6 to move away from the pre-twisted wire positioning device 100. At the same time, under the action of the rack 9, the bottom gear 632 meshing with it will rotate. The rotating bottom gear 632 will sequentially drive the vertical rotating shaft 63, the top helical gear 631, the wing plate helical gear 642, the wing plate rotating shaft 641, the wing plate gear 643, and the driven gear ring 81 to rotate. The driven gear ring 81 drives the winding seat ring 8 and the clamp assembly to rotate. The clamp assembly will pull the pre-twisted wire to wind on the cable 600. The distance traveled by the pre-twisted wire winding device 200 determines the rotation angle of the driven gear ring 81. Therefore, the pitch value of the pre-twisted wire winding can be ensured, so that the pre-twisted wire can be stably wound on the cable 600. After the pre-twisted wire is wound, the clamp assembly releases the pre-twisted wire, and the end of the pre-twisted wire can be manually twisted and tidied.

[0066] Step S4: Wind the second pre-twisted wire, rotate the positioning threaded rod 32 to loosen the clamping of the positioning clamp 31 on the cable 600, rotate the positioning seat ring 2 to rotate it at a certain angle, and then rotate the positioning threaded rod 32 again to press the end of the second pre-twisted wire onto the cable 600 through one of the positioning clamps 31, with the end of the second pre-twisted wire close to the end of the first pre-twisted wire, and the other positioning clamps 31 pressing onto the cable 600. Then, repeat step S3... in a cycle until all the pre-twisted wires are wound.

[0067] Obviously, the present invention can reasonably arrange the number of positioning and clamping mechanisms 3 and clamping components so as to complete the winding of multiple pre-twisted wires at one time.
