Description

Technical Field

[0001] This utility model relates to the field of power cable laying technology, specifically to a power cable laying device. Background Technology

[0002] Power cables are cables used for transmitting and distributing electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing. Power cables are cable products used in the main lines of power systems to transmit and distribute high-power electrical energy, including power cables of various voltage levels from 1-500kV and above, and various types of insulation.

[0003] A utility model patent with patent authorization announcement number CN114803703A discloses a power cable laying device. Its structure includes a vehicle body, handle, a drum holder, a traction mechanism, and casters. The unwinding drum is installed through the telescopic rod and clamp inside the drum holder on the vehicle body. When the cable is used up, the unwinding drum can be replaced simply by moving the rod. The operation is simple and convenient, greatly improving efficiency. The traction mechanism can pull out the cable by using a linkage when pushing the vehicle body. The fixing device can be adjusted according to the size of the cable, avoiding damage to the insulation layer of the cable surface due to friction during the laying process, improving service life, and eliminating safety hazards.

[0004] Currently, when assembling and connecting U-shaped channels for power cable installation, multiple bolts are often used for positioning and fixing. However, after the bolts are positioned and then disassembled, threaded holes are left behind. Repeated disassembly increases the inner diameter of the threaded holes, thereby affecting the positioning effect of the bolts and the assembly and connection effect of the U-shaped channel. At the same time, the positioning stability of the power cable is not good when it is laid inside the U-shaped channel, so the power cable is easy to detach from the inside of the U-shaped channel, affecting the installation stability of the power cable. Utility Model Content

[0005] The purpose of this invention is to provide a power cable laying device that solves the problems of assembling and connecting U-shaped grooves and laying power cables.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power cable laying device, comprising a first cable tray and a second cable tray, wherein a connecting seat is slidably connected at the connection between the first cable tray and the second cable tray, the connecting seat is provided with a limiting mechanism, and multiple power cables are slidably connected inside the first cable tray and the second cable tray, and the first cable tray and the second cable tray are respectively provided with a pressing mechanism.

[0007] Preferably, the limiting mechanism includes a groove, and the first and second wiring grooves are respectively provided with multiple grooves. A spring is fixedly connected inside the groove, and a locking block is fixedly connected to one end of the spring.

[0008] Preferably, the locking block is slidably connected to the inside of the groove, the locking block has an anti-detachment groove, and an anti-detachment block is slidably connected inside the anti-detachment groove.

[0009] Preferably, the anti-detachment block is fixedly connected to the inside of the groove, the connecting seat has multiple slots, and the locking block is slidably connected to the inside of the slots.

[0010] Preferably, the pressing mechanism includes a limiting plate, the upper ends of the first and second wiring channels are respectively fixedly connected to the limiting plate, the limiting plate is rotatably connected to a pressure rod by a thread, and the upper end of the pressure rod is fixedly connected to a handle.

[0011] Preferably, a positioning block is fixedly connected to the lower end of the pressure rod, and a pressing block is rotatably connected to the positioning block.

[0012] Preferably, a buffer pad is fixedly connected to the lower end of the extrusion block, and the extrusion block presses down on the buffer pad to fit tightly against the upper end of the power cable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model has multiple grooves in the connecting seat, and springs connect the locking blocks inside the grooves to limit their movement. Multiple locking slots are opened in the first and second wiring channels respectively. The springs automatically stretch and push the locking blocks to slide and engage inside the locking slots, thereby fixing the connecting seat inside the first and second wiring channels. This limits and fixes the first and second wiring channels, preventing them from coming apart, facilitating assembly, and preventing damage to the limiting mechanism after repeated assembly and disassembly, without affecting the assembly connection effect.

[0015] 2. This utility model uses limiting plates connected to the upper ends of the first and second cable trays respectively. The limiting plates limit the pressure rod, and the lower end of the pressure rod can limit the squeezing block through the positioning block. Thus, the squeezing block presses down the buffer pad tightly against the upper end of the power cable, thereby limiting and pressing down the power cable to prevent the power cable from moving and leaving the interior of the first and second cable trays, and increasing the stability of the limiting.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A power cable laying device includes a first cable tray 1 and a second cable tray 2. The first cable tray 1 and the second cable tray 2 are U-shaped to facilitate the storage of power cables 5. A connecting seat 3 is slidably connected at the connection between the first cable tray 1 and the second cable tray 2. The connecting seat 3 is provided with a limit mechanism 4. Multiple power cables 5 are slidably connected inside the first cable tray 1 and the second cable tray 2. The first cable tray 1 and the second cable tray 2 are respectively provided with a pressing mechanism 6. This technical solution improves upon the problems raised in the background art. Other technical problems of this technical solution are existing technologies and will not be described in detail here.

[0023] Please see Figure 1 , Figure 2 , Figure 4The limiting mechanism 4 includes a groove 41. The first wiring groove 1 and the second wiring groove 2 are respectively provided with multiple grooves 41. A spring 42 is fixedly connected inside the groove 41. A locking block 43 is fixedly connected to one end of the spring 42. The locking block 43 is slidably connected inside the groove 41. The locking block 43 is provided with an anti-detachment groove 44. An anti-detachment block 45 is slidably connected inside the anti-detachment groove 44. Through the slidable connection between the anti-detachment groove 44 and the anti-detachment block 45, the locking block 43 is limited to prevent it from detaching from the inside of the groove 41, thus playing a limiting and fixing role. The anti-detachment block 45 is fixedly connected inside the groove 41. The connecting seat 3 is provided with multiple slots 46. Through the elastic action of the spring 42, the locking block 43 can be automatically reset and automatically slide into the slot 46, thereby achieving the function of automatically connecting the connecting seat 3. The locking block 43 is slidably connected inside the slot 46.

[0024] Please see Figure 1 , Figure 2 , Figure 3 The pressing mechanism 6 includes a limiting plate 61. The upper ends of the first cable tray 1 and the second cable tray 2 are respectively fixedly connected to the limiting plate 61. The limiting plate 61 is rotatably connected to the pressure rod 62 by a thread. The pressure rod 62 is easily rotated by the handle 63. The upper end of the pressure rod 62 is fixedly connected to the handle 63, and the lower end of the pressure rod 62 is fixedly connected to the positioning block 64. The positioning block 64 is rotatably connected to the pressing block 65. The positioning block 64 limits the connection between the pressure rod 62 and the pressing block 65, and prevents the pressing block 65 from rotating when the pressure rod 62 is rotated, thus playing a limiting role. The lower end of the pressing block 65 is fixedly connected to the buffer pad 66. The buffer pad 66 increases the friction and increases the stability of the limiting power cable 5. The pressing block 65 presses down on the buffer pad 66 and is tightly attached to the upper end of the power cable 5.

[0025] The specific implementation process of this utility model is as follows: When it is necessary to assemble the first wiring groove 1 and the second wiring groove 2, the sliding locking connector 3 is used so that the connection between the first wiring groove 1 and the second wiring groove 2 is slidably locked inside the connector 3. Then, the spring 42 presses the locking block 43 so that the locking block 43 is slidably locked inside the corresponding locking groove 46. At the same time, the anti-detachment groove 44 and the anti-detachment block 45 are slidably connected. Then the first wiring groove 1 and the second wiring groove 2 can be assembled and connected.

[0026] Then, multiple power cables 5 are slidably clipped into the inside of the first cable tray 1 and the second cable tray 2, and simultaneously slid through the lower end of the buffer pad 66. Then, the handle 63 is turned, and the handle 63 is turned to press down the pressure rod 62. The pressure rod 62 drives the positioning block 64 to rotate, and at the same time, the positioning block 64 is rotatably connected to the pressing block 65. Then, the pressing block 65 presses down on the buffer pad 66 and presses it tightly against the upper end of each power cable 5, thereby limiting and fixing each power cable 5.
