Description

Technical Field

[0001] This utility model relates to the field of wire laying technology, specifically to a device for laying stranded wires of power cables. Background Technology

[0002] In the prior art, cable core stranding laying devices typically include basic components such as a base, a drive mechanism, and a guide structure. The drive component moves the cable core, while the guide component limits the cable to complete the stranding laying operation.

[0003] However, in practical applications, existing devices for cable cutting often use fixed installation methods for hydraulic shears, which are cumbersome to disassemble and assemble. When it is necessary to replace or maintain the cutting tool, a lot of time is required, reducing construction efficiency. In addition, some devices lack effective cable limiting structures, which can easily cause the stranded wire to loosen due to axial movement of the cable during the stranding process, further affecting the construction quality. Therefore, a power cable core stranding laying device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for laying stranded wires of power cables, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power cable core stranding laying device, comprising:

[0006] The base has a lifting mechanism installed on one side of its upper end. A side frame is installed on the lifting end of the lifting mechanism. A second drive motor is installed on the outer side of the side frame. The output end of the second drive motor is located inside the side frame and a drive roller is installed. The height of the side frame and the drive roller can be flexibly adjusted through the lifting mechanism to adapt to the laying height requirements of different specifications of cable cores and improve the adaptability of the device to different construction scenarios.

[0007] Guide grooves are formed on both sides of the upper inner end of the side frame. Guide blocks are slidably installed inside the guide grooves, and transmission rollers are rotatably installed between the guide blocks. A first return spring is installed on the upper end of the guide block. The guide block slides in the guide groove and cooperates with the elastic force of the first return spring to make the transmission rollers closely fit the cable cores of different diameters, effectively avoiding cable deviation and shaking during the twisting process and ensuring laying accuracy.

[0008] There are two retaining rings, which are spaced apart at the rear of the side frame. The spaced retaining rings axially limit the cable core to prevent axial movement of the cable during the twisting process, avoid loosening of the twisted wire, and ensure construction quality.

[0009] A telescopic side rod is set on the outer side of the side frame. A ring shell is installed at the rear end of the telescopic side rod. An electric hydraulic cable cutter is inserted inside the ring shell. An annular groove is opened on the outside of the electric hydraulic cable cutter.

[0010] The inner cavity is located on the upper and lower sides inside the ring shell. A limit block is installed inside the inner cavity, and a pull rod is installed outside the limit block. The pull rod passes through and extends to the outside of the ring shell. A second return spring is installed inside the inner cavity outside the pull rod. By pulling the limit block to compress the second return spring through the pull rod, the electric hydraulic cable cutter can be quickly inserted and fixed or disassembled with the ring shell, simplifying the cutter replacement and maintenance process and improving construction efficiency.

[0011] Preferably, the lifting mechanism includes a vertical housing, a first drive motor, a drive screw, and a slider, with the side frame connected to the slider, and the drive screw installed at the output end of the first drive motor.

[0012] Preferably, the first drive motor is mounted on the top of the upright housing, the slider is slidably connected to the upright housing, and the slider is connected to the drive screw through a threaded engagement.

[0013] Preferably, casters are installed at the four corners of the lower end face of the base, and the casters are connected to the base so that the device can move.

[0014] Preferably, a telescopic parallel frame is mounted on the rear of the base via a damping pivot, and a handrail is installed inside the rear end of the telescopic parallel frame to facilitate the pushing and pulling of the moving device.

[0015] Preferably, both the drive roller and the transmission roller are provided with anti-slip strips on their exterior, and the anti-slip strips are fixedly connected to the drive roller and the transmission roller, thereby improving the anti-slip capability of the drive roller and the transmission roller.

[0016] Compared with the prior art, this utility model provides a device for laying stranded wires of power cables, which has the following advantages:

[0017] This invention achieves flexible height adjustment of the drive roller and transmission roller through the cooperation of the lifting mechanism and the side frame, which is beneficial for adapting to the laying height requirements of different specifications of cable cores and solves the problems of fixed height and poor adaptability of traditional devices. The combination of the guide groove, guide block and the first return spring realizes the elastic compression of the cable core by the transmission roller, which is beneficial for ensuring the stability of the cable during the stranding process and solving the problem of cable shaking caused by insufficient guide fit. The setting of the retaining ring realizes the axial limit of the cable core, which is beneficial for preventing the cable from moving and loosening during the stranding process and solving the construction quality problems caused by the lack of effective limit. The cooperation of the telescopic side rod, ring shell and limit block and the second return spring realizes the quick assembly and disassembly of the electric hydraulic cable cutter, which simplifies the cutter replacement and maintenance process and solves the problems of cumbersome assembly and disassembly and low efficiency of the cutter under the traditional fixed installation method.

[0022] 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.

[0023] This utility model provides a technical solution: a device for laying stranded wires in power cables. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include:

[0024] A base 1 is provided with a lifting mechanism installed on one side of the upper end of the base 1. A side frame 9 is installed on the lifting end of the lifting mechanism. A second drive motor 12 is installed on the outer side of the side frame 9. The output end of the second drive motor 12 is located inside the side frame 9 and a drive roller 13 is installed thereon.

[0025] Guide grooves 16 are opened on both sides of the upper inner end of the side frame 9. Guide blocks 17 are slidably installed inside the guide grooves 16. A transmission roller 14 is rotatably installed between multiple guide blocks 17. A first return spring 18 is installed on the upper end of the guide block 17.

[0026] There are two retaining rings 10, and the two retaining rings 10 are spaced apart at the rear of the side frame 9;

[0027] Telescopic side rod 25 is set on the outer side of side frame 9. An annular shell 19 is installed at the rear end of telescopic side rod 25. An electric hydraulic cable cutter 11 is inserted inside the annular shell 19. An annular groove 20 is opened on the outside of the electric hydraulic cable cutter 11.

[0028] The inner cavity 21 is opened on the upper and lower sides inside the ring shell 19. A limit block 24 is installed inside the inner cavity 21. A pull rod 22 is installed outside the limit block 24. The pull rod 22 passes through and extends to the outside of the ring shell 19. A second return spring 23 is installed outside the pull rod 22 inside the inner cavity 21.

[0029] Please see Figure 1 The lifting mechanism includes a vertical housing 5, a first drive motor 6, a drive screw 7, and a slider 8, with the side frame 9 connected to the slider 8, and the drive screw 7 installed at the output end of the first drive motor 6.

[0030] Please see Figure 1 The first drive motor 6 is installed on the top of the vertical shell 5, the slider 8 is slidably connected to the vertical shell 5, and the slider 8 is connected to the drive screw 7 by a threaded engagement.

[0031] Please see Figure 1 The base 1 has casters 2 installed at the four corners of its lower end face, and the casters 2 are connected to the base 1 so that the device can move.

[0032] Please see Figure 1 The rear of the base 1 is equipped with a telescopic parallel frame 3 via a damping pivot. The rear end of the telescopic parallel frame 3 is equipped with a handrail 4 for pushing and pulling the moving device.

[0033] Please see Figure 1 and Figure 2 Both the drive roller 13 and the transmission roller 14 are provided with anti-slip strips 15 on their exteriors, and the anti-slip strips 15 are fixedly connected to the drive roller 13 and the transmission roller 14. The anti-slip strips 15 improve the anti-slip ability of the drive roller 13 and the transmission roller 14.

[0034] This solution involves flipping and stretching the telescopic parallel frame 3 upwards, causing the handrail 4 to be pulled to the required height and position. Pulling the handrail 4 causes the base 1 to roll in conjunction with the casters 2, thereby moving the device to the required position. Pulling the telescopic side rod 25 causes the ring shell 19 to move outwards. Pulling the pull rod 22 causes the limiting block 24 to retract into the inner cavity 21 and inserts the tail of the electric hydraulic cable cutter 11 into the ring shell 19. Releasing the pull rod 22 causes the second return spring 23 to reset and push the limiting block 24 into the ring groove 20, thereby limiting the electric hydraulic cable cutter 11.

[0035] The cable core to be laid is passed through the electric hydraulic cable cutter 11 and the side frame 9. The second drive motor 12 is started to make the drive roller 13 rotate. The drive roller 13 conveys the cable core for laying. With the first reset spring 18 pressing down on the guide block 17, the transmission roller 14 is made to fit against the top of the cable core. The first drive motor 6 is controlled to make the drive screw 7 rotate. The slider 8 and the drive screw 7 are connected by a thread and a sliding connection with the vertical shell 5, which converts the rotational motion of the drive screw 7 into the linear motion of the slider 8, thereby driving the side frame 9 to rise and fall.
