Description

Technical Field

[0001] This invention belongs to the field of overhead cable technology, specifically relating to a retractable dual-channel overhead cable device and its usage method. Background Technology

[0002] In construction and power engineering projects, overhead cable laying is a crucial step in ensuring construction safety and cable performance. Traditional overhead cable installations often use triangular pyramid supports, which are simple in structure but have significant drawbacks, making them unsuitable for complex construction site requirements. Specifically:

[0003] 1. Limitations of fixing method: Triangular cone brackets achieve stability through three-point support, but in complex terrain, the three-point support is prone to tilting or collapse due to uneven force distribution. Especially on slopes or soft ground, the support force is significantly reduced, which can easily lead to safety hazards such as cable falling or water damage.

[0004] 2. Insufficient terrain adaptability: The support legs of traditional brackets have a fixed length, which cannot cope with uneven terrain or terrain with obstacles. For example, when the cable needs to cross ditches or rocks, it is difficult to adjust the height to keep the cable horizontal, causing the cable to sag or come into contact with the ground, damaging the cable performance.

[0005] 3. Fixed height and single function: Traditional supports have a fixed height, which cannot meet the needs of overhead cables in local pitted areas during rainy weather. In addition, only one cable can be installed on the same support, and effective installation cannot be carried out at cable crossings, resulting in low construction efficiency.

[0006] 4. Inconvenient installation and disassembly: The traditional triangular pyramid bracket has a complicated installation and disassembly process, which consumes a lot of manpower and time and is difficult to adapt to the needs of rapid operation on the construction site.

[0007] In view of the shortcomings of the existing technology, there is an urgent need for an overhead cable device and its usage method that can flexibly adapt to different terrains, be stable and reliable, be efficient in construction and have multi-channel erection function, so as to solve the technical problems existing in the current technology. Summary of the Invention

[0008] The purpose of this invention is to provide a retractable dual-channel overhead power cable device and its usage method, to solve the technical problems of existing triangular pyramid overhead power cable devices, such as insecure fixation, inability to adapt to complex terrain, ability to support only one power cable per support, and low construction efficiency. This device adopts a four-legged telescopic structure design, allowing for flexible height adjustment to adapt to complex terrain and improve support stability. It also features dual-channel erection capability, enabling rapid installation and dismantling, and providing reliable protection for the safe overhead cable laying at construction sites.

[0009] The specific technical solution adopted by this invention is as follows:

[0010] A retractable dual-channel overhead power line device includes a four-legged support frame, which consists of a top plate and four support legs fixedly connected to the lower surface of the top plate. The four support legs are arranged in a frustum shape.

[0011] Each of the support legs includes a fixed section and a telescopic section. The upper end of the fixed section is fixedly connected to the lower surface of the top plate, and the lower end of the fixed section has a slot extending along its length. The fixed section has multiple through-holes on both sides of the slot. The upper part of the telescopic section is adapted to the slot and can be telescopically inserted into the fixed section along the length of the slot. The upper sides of the telescopic section have positioning grooves that match the connecting holes. By aligning the positioning grooves on the telescopic section with the connecting holes of different heights on the fixed section, and then using a locking structure to pass through the connecting holes and positioning grooves, the installation position of the telescopic section relative to the fixed section can be adjusted, thereby adjusting the overall height of the four-leg support frame.

[0012] Independent cable laying channels are provided above and below the top plate of the four-legged support frame.

[0013] Preferably, the bottom of the telescopic section is detachably connected to an anti-slip pad or gripping teeth.

[0014] Preferably, the locking structure is a spiral locking structure.

[0015] Preferably, the spiral locking structure includes a bolt and an anti-slip washer fixedly disposed at the end of the bolt.

[0016] Preferably, a cable laying platform is fixedly installed above the top plate of the four-legged support frame, and a first cable laying channel is provided on the cable laying platform. The first cable laying channel and the cable laying channel below the top plate form an independent dual-channel structure.

[0017] Preferably, a detachable diagonal brace is cross-connected between two adjacent fixed sections, and a second cable laying channel is formed between the detachable diagonal brace and the top plate. The second cable laying channel is the cable laying channel below the top plate.

[0018] In addition, the present invention also discloses a method of using a retractable dual-channel overhead power line device. The method of using the aforementioned retractable dual-channel overhead power line device includes the following steps:

[0019] Step 1: Preparation work, prepare the retractable dual-channel overhead cable device and cable fixing clamp, survey the terrain of the construction site, plan the cable laying path, determine the installation position of the device and mark it on the ground;

[0020] Step 2: Device adjustment and installation. Move the telescopic dual-channel overhead power line device to the marked position. Adjust the height of each of the four support legs independently according to the actual terrain of the construction site to keep the device level. After adjustment, insert the locking structure through the connection hole of the fixed section and the positioning groove of the telescopic section to fix the height of the support legs.

[0021] Step 3: Cable installation. Place the cables in the two independent cable trays above and below the top plate, and use cable clamps to hold and fix the cables in the corresponding cable trays to complete the cable installation and fixing.

[0022] Compared with the prior art, the present invention has at least one of the following advantages or beneficial effects:

[0023] 1. Significantly Improved Stability: Addressing the issue of traditional triangular pyramid supports being prone to tilting and collapse due to their three-point support, this invention employs a four-legged telescopic structure. The four independently adjustable support legs create a larger contact area with the ground. In complex terrain, even if some support legs experience uneven stress, the remaining support legs can still maintain overall balance, significantly enhancing anti-overturning capability and effectively preventing cables from falling due to device instability, thus providing more reliable safety assurance for construction sites. At the same time, the anti-slip pads or gripping teeth at the bottom of the telescopic section further improve the device's stability on different ground surfaces.

[0024] 2. Strong terrain adaptability: Traditional support legs have fixed lengths, making it difficult to cope with complex terrain. However, the support legs of this invention can be flexibly adjusted in height according to the actual conditions of the construction site. Each support leg can be adjusted independently. Whether crossing ditches, avoiding rocks, or on uneven ground, each support leg can be quickly adjusted to ensure that the cable is always kept in a horizontal overhead state. It can easily adapt to various complex terrain environments and meet the requirements for safe cable laying.

[0025] 3. Flexible and Adjustable Height: Existing brackets have a fixed height, which cannot meet the requirements for overhead cables in special weather or complex scenarios. The quick-extension adjustment function of this invention allows for timely height adjustment when rain causes uneven ground, ensuring a safe distance between the cable and the ground. At cable crossings, effective installation can also be achieved by adjusting the height, greatly improving the versatility and practicality of the device.

[0026] 4. Significantly improved construction efficiency: The support legs of this invention adopt a modular design, and the detachable diagonal braces facilitate installation and disassembly. The locking structure is easy to operate, enabling rapid installation and disassembly of the device and saving construction time. At the same time, the dual-channel design allows two cables to be erected simultaneously, meeting multiple needs with a single installation, reducing repetitive operations, further improving construction efficiency, and providing strong support for the smooth progress of the project.

[0027] 5. Rigorous structure and strong practicality: The connection of each component of the device is reliable, and the locking structure is reasonably designed to effectively prevent the support feet from loosening; detachable parts (such as anti-slip pads, grip teeth, and diagonal braces) facilitate later maintenance and replacement, adapt to different construction scenarios, and extend the service life of the device.

[0032] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0033] Example 1:

[0034] like Figure 1 and 2 As shown in the figure, this embodiment discloses a retractable dual-channel overhead power line device. Specifically, the device includes a four-legged support frame, which consists of a top plate and four support legs fixedly connected to the lower surface of the top plate. The four support legs are arranged in a truncated quadrangular shape. This arrangement can further distribute the force on the device and improve the overall stability.

[0035] Each support leg includes a fixed section 1 and a telescopic section 2. The upper end of the fixed section 1 is integrally formed with the lower surface of the top plate. The lower end of the fixed section 1 has a slot extending along its length, and the cross-sectional shape of the slot matches the upper cross-sectional shape of the telescopic section 2 (preferably rectangular). The fixed section 1 has multiple through-holes spaced apart on both sides of the slot. The spacing of the through-holes is set according to actual adjustment needs, preferably 1-3cm, allowing for precise adjustment of the support leg height. Specifically, the upper part of the telescopic section 2 is adapted to the slot and can be telescopically inserted into the fixed section 1 along the length of the slot. Positioning grooves matching the connecting holes are opened on both sides of the upper part of the telescopic section 2, and the diameter of the positioning grooves is consistent with the connecting holes. When the telescopic section 2 is adjusted to a suitable height, the positioning grooves on the telescopic section 2 are aligned with the corresponding connecting holes on the fixed section 1. Then, a locking structure 3 is used to pass through the connecting holes and positioning grooves to fix the installation position of the telescopic section 2 relative to the fixed section 1, thereby adjusting the height of each support leg of the four-legged support frame. The adjustment range is preferably about 0.8m, and can be expanded according to construction needs.

[0036] In this embodiment, the locking structure 3 adopts a spiral locking structure, including a locking bolt 31 and an anti-slip washer 32 fixedly disposed at the end of the locking bolt 31. The anti-slip washer 32 is made of rubber, which can enhance the friction between the locking bolt 31 and the fixed section 1 and the telescopic section 2, prevent the locking bolt 31 from loosening after the device is subjected to force, and prevent the telescopic section 2 from automatically retracting.

[0037] The bottom of the telescopic section 2 is detachably connected to an anti-slip pad or grip teeth via connecting bolts. When the construction site is a hard surface, the anti-slip pad is installed to enhance the anti-slip performance of the device. When the construction site is a soft surface such as mud or sand, the grip teeth are replaced to improve the grip of the device and further enhance the device's anti-overturning ability.

[0038] A cable-laying platform 5 is welded and fixed above the top plate of the four-legged support frame. The cable-laying platform 5 is equipped with a first cable-laying channel, which can be used to lay the first cable 6. A detachable diagonal brace 4 is cross-connected between two adjacent fixed sections 1. The detachable diagonal brace 4 is fastened to the fixed section 1 for easy installation and disassembly. The detachable diagonal brace 4 and the top plate form a second cable-laying channel, which is the cable-laying channel below the top plate, and can be used to lay the second cable 7. The first cable-laying channel and the second cable-laying channel form an independent dual-channel structure, which can realize the independent overhead laying of two cables, avoid cross-entanglement, and solve the shortcomings of traditional devices where the cross-position of cables cannot be supported.

[0039] Example 2:

[0040] This embodiment discloses a method for using a retractable dual-channel overhead power line device. The method of using the retractable dual-channel overhead power line device described in the above embodiment includes the following steps:

[0041] Step 1: Preparation. Prepare the retractable dual-channel overhead cable device and cable clamps. Survey the terrain of the construction site, plan the cable laying route, determine the installation location of the device, and mark it on the ground.

[0042] Step 2: Device Adjustment and Installation. Move the retractable dual-channel overhead power line device to the marked location. Adjust the height of each of the four support legs independently according to the actual terrain of the construction site. If it is on a slope, extend the telescopic section of the lower support leg and shorten the telescopic section of the higher support leg. If it needs to cross a ditch, adjust the height of the support legs according to the depth and width of the ditch so that the device can cross the ditch and remain horizontal. After adjustment, insert the bolts of the locking structure through the connecting holes of the fixed section and the positioning groove of the telescopic section, and tighten the bolts to fix the height of the support legs. At the same time, depending on the ground conditions, install anti-slip pads or gripping teeth at the bottom of the telescopic section, and connect detachable diagonal braces between adjacent fixed sections.

[0043] Step 3: Cable installation. Place the first and second cables in the two independent cable laying channels above and below the top plate, respectively. Use cable clamps to hold and fix the cables in the corresponding cable laying channels to complete the installation and fixation of the cables, ensuring that the cables will not slip or fall off.

[0044] Step 4: Installation, inspection and adjustment. After installation, shake the device to confirm that there is no obvious shaking. Check whether the cable clamp is clamping the cable, whether the bolts are loose, and whether the detachable diagonal brace is securely connected. If the device is found to be unstable or the cable is not securely fixed, make adjustments in time, such as readjusting the height of the support feet, reinforcing the cable clamp, and tightening the bolts.

[0045] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
