Technical Field

[0001] A cable laying device for electromechanical installation is used for laying cables for electromechanical installation, belonging to the technical field of cable laying devices. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors. Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. The main wire and cable products used in power systems include overhead bare wires, busbars, power cables, branch cables, magnet wires, and electrical equipment wires and cables for power equipment. When cables are laid vertically in cable trays, the upper end of the cable and every 1.5m interval should be fixed to the tray supports; when laid horizontally, the beginning, end, bends, and every 5-10m interval should be fixed. Cables should be bundled when laid in horizontal and vertical cable trays and vertical cable troughs. Twisted-pair cables, optical cables, and other signal cables should be bundled according to cable type, diameter, number of cores, and quantity. The bundling spacing should not exceed 1.5m, and the spacing should be uniform and the tightness moderate. Optical cables inside the building are suitable for laying in metal cable trays. When laying them in cable trays, pads should be added to the binding and fixing sections.

[0003] Publication (Announcement) No.: CN219018305U, discloses a cable laying vehicle, belonging to the technical field of power transmission and transformation engineering construction equipment.

[0004] The purpose of this utility model is to provide a cable laying device for electromechanical installation, which solves the problem that the mobile laying method for laying cables requires the entire device to be moved, resulting in low cable laying efficiency and affecting the overall work progress of the project.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cable laying device for electromechanical installation includes a support box, a quick installation mechanism for fixing the support box on the cable laying path, and a sliding fixing mechanism for guiding and limiting the laying of the cable on the support box. The support box has an inlet hole and an outlet hole for the cable to pass through and out.

[0006] Furthermore, the quick installation mechanism includes a fixing component fixedly installed on the cable laying path and an installation component disposed on the support box and cooperating with the fixing component to fix the support box.

[0007] Furthermore, the fixing component includes a fixing post fixedly installed on the cable laying path, a locking block disposed on the fixing post, and a locking slot provided on the locking block.

[0008] Furthermore, the mounting assembly includes a connecting rod mounted on a support box, a friction disc rotatably mounted on the connecting rod, and a fixing plate that mates with a slot on the friction disc.

[0009] Furthermore, the fixing plate and the slot are interference-fitted.

[0010] Furthermore, the sliding fixing mechanism includes a partition plate disposed inside the support box to separate the support box into an installation frame. The partition plate is provided with connection ports corresponding to the inlet and outlet holes. A first installation rod and a second installation rod are disposed on the installation frame on the two sides adjacent to the connection ports and are separated from each other. A first sliding wheel and a second sliding wheel corresponding to the connection ports are rotatably connected to the first installation rod and the second installation rod through bearing sleeves. The first sliding wheel and the second sliding wheel disposed opposite to each other guide and limit the cable.

[0011] Furthermore, a sliding groove is provided on the mounting frame of the second mounting rod, the second mounting rod is slidably mounted on the mounting frame, a fixing block is provided on the second mounting rod, and a spring is provided between the fixing block and the support box to push the second mounting rod closer to the first mounting rod.

[0012] Furthermore, there are two mounting frames.

[0013] Furthermore, the support box is fitted with a first connecting box and a second connecting box to protect one side of the slide groove.

[0014] Furthermore, an inlet pipe and an outlet pipe are respectively provided on the inlet and outlet holes.

[0015] Compared with the prior art, the advantages of this utility model are: I. This invention uses a quick-installation mechanism to install the support box and sliding fixing mechanism on the cable laying path, which makes the cable laying efficiency high and the overall work progress of the project improved. It effectively avoids the problem that the entire device needs to be moved when using a mobile erection method to erect the cable. At the same time, the cable is lifted and separated from the ground by the sliding fixing mechanism, which can effectively reduce friction with the ground during the pulling process and effectively avoid damage to the outer rubber sleeve of the cable. Second, the quick installation mechanism of this utility model first installs the fixing component on the cable laying path, and then fixes the support box and the sliding fixing mechanism by cooperating with the installation component on the support box and the fixing component. That is, the support box and the sliding fixing mechanism are quickly installed on the cable laying path (such as the side wall of a manhole) by the interference fit between the card block and the card slot. Third, the sliding fixing mechanism in this utility model guides and limits the cable laying by rotating the first sliding wheel and the second sliding wheel on the oppositely arranged first mounting rod and second mounting rod. This not only prevents the cable from deviating during the pulling process, but also effectively reduces the friction generated during the pulling process. Fourth, in this utility model, a sliding groove is provided on the mounting frame to allow the second mounting rod to slide. This not only makes it suitable for guiding cables of different diameters, but also allows the spring to apply a reset pushing force to the second mounting rod, so that the second mounting rod is close to the first mounting rod, thereby limiting the cable with the first and second sliding wheels on it to prevent the cable from slipping off the first and second sliding wheels. V. The support box of this utility model has two mounting frames, which is intended to facilitate better guidance and positioning of the cable during installation. VI. This device is equipped with a first connecting box and a second connecting box on the support box. The purpose is to protect the slide groove and prevent impurities from entering the support box.

[0025] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0026] Example 1 To address the issue that mobile cable laying methods require moving the entire installation, resulting in low cable laying efficiency and impacting the overall project schedule, [the following is an example / example]. Figure 1-5 As shown, a cable laying device for electromechanical installation is provided, including a support box 1, a quick-installation mechanism 5 for fixing the support box 1 on the cable laying path, and a sliding fixing mechanism 6 provided on the support box 1 for guiding and limiting the laying of the cable. The support box 1 has an inlet hole and an outlet hole opposite to each other for the cable to pass through. The sliding fixing mechanism 6 is used to move the cable to reduce cable friction. The quick-installation mechanism 5 is used for rapid installation of the entire device.

[0027] In practice, the support box 1 and the sliding fixing mechanism 6 are fixed to the cable laying path using the quick installation mechanism 5. One or more mechanisms can be installed on the cable laying path. The cable is then inserted into the support box 1 through the manhole and exits through the manhole after engaging with the sliding fixing mechanism 6. This embodiment uses a quick installation mechanism to install the support box and sliding fixing mechanism on the cable laying path, resulting in high cable laying efficiency and improved overall project progress. It effectively avoids the problem of needing to move the entire device when using a mobile installation method for cables. Simultaneously, the sliding fixing mechanism lifts the cable away from the ground, effectively reducing friction with the ground during pulling and preventing damage to the cable's outer rubber sleeve.

[0028] Example 2 Based on Embodiment 1, the quick installation mechanism 5 includes a fixing component 51 fixedly installed on the cable laying path and an installation component 52 disposed on the support box 1 and cooperating with the fixing component 51 to fix the support box 1. The fixing component 51 includes a fixing post 511 fixedly installed on the cable laying path, a locking block 512 disposed on the fixing post 511, and a locking groove 524 disposed on the locking block 512. The installation component 52 includes a connecting rod 521 disposed on the support box 1, a friction disc 522 rotatably disposed on the connecting rod 521, and a fixing plate 523 disposed on the friction disc 522 that cooperates with the locking groove 524. The fixing plate 523 and the locking groove 524 are interference-fitted.

[0029] In practice, the fixing column 511 is fixedly installed on the side wall of the electric well, and then the friction disc 522 is rotated. The device is quickly installed by the interference fit between the fixing plate 523 on the outer wall of the fixing column 511 and the slot 524.

[0030] Example 3 Based on Embodiment 2, the sliding fixing mechanism 6 includes a partition plate disposed within the support box 1, separating the support box 1 into a mounting frame 61. The partition plate has connection ports 62 corresponding to the inlet and outlet holes. A first mounting rod 63 and a second mounting rod 65, separated from each other, are disposed on the mounting frames 61 on opposite sides of the connection ports 62. A first sliding wheel 64 and a second sliding wheel 66, corresponding to the connection ports 62, are rotatably connected to the first mounting rod 63 and the second mounting rod 65 via bearing sleeves. The opposing first sliding wheels 64 and the second sliding wheel 66 guide and limit the cable. A sliding groove is provided on the mounting frame 61 where the second mounting rod 65 is disposed. The second mounting rod 65 is slidably disposed on the mounting frame 61. A fixing block 67 is provided on the second mounting rod 65. A spring 68, which resets and pushes the second mounting rod 65 towards the first mounting rod 63, is disposed between the fixing block 67 and the support box 1.

[0031] In practice, when laying and installing cables, it is necessary to pull the cables. However, cables are generally heavy wires, and they will rub against the ground when pulled. Therefore, the support box 1 is separated into mounting frames 61 by a partition plate. A connection port 62 is opened on the partition plate to allow the cable to pass through. There can be one partition plate or multiple partition plates to form multiple mounting frames. In this case, two mounting frames 61 are formed (the mounting frame 61 is composed of a partition plate and a support box, such as...). Figure 4As shown, one side of the connection port 62 is a partition plate, and the rest is part of the support box. Considering issues such as easy cable passage (though other possibilities are not excluded), and because the cable size is not uniformly fixed, a first mounting rod 63 is fixedly connected to the inner wall of the mounting frame 61 during use. A first sliding wheel 64 is fixedly connected to the outer wall of the first mounting rod 63 via a bearing. A second mounting rod 65 is movably connected to the outer wall of the mounting frame 61. A second sliding wheel 66 is fixedly connected to the outer wall of the second mounting rod 65 via a bearing. The first sliding wheel 64 and the second sliding wheel 66 clamp the cable in the middle, reducing the resistance to cable movement and effectively preventing friction between the cable and the ground during pulling, which could damage the outer rubber sleeve of the cable. If the cable is too thick, it can be compressed by the spring 68, widening the gap between the first mounting rod 62 and the second mounting rod 65 to ensure the safe passage and fixation of the cable.

[0032] Example 4 Based on embodiment 3, the support box 1 is fitted with a first connecting box 2 and a second connecting box 3 to protect one side of the slide groove. The purpose is to facilitate the protection of the slide groove and prevent impurities from entering the support box.

[0033] In summary, when multiple devices are installed in layers, layering the cables ensures full utilization of the space in the manhole tunnel, allows for reasonable cable arrangement within the manhole, prevents cable accumulation, and guarantees the connection and laying of multiple cables. The inlet and outlet holes can also be equipped with inlet pipes 4 and outlet pipes 7, respectively.
