Technical Field
[0001] This invention relates to the field of power cable installation technology, specifically to a vertical installation device for power cables. Background Technology
[0002] In power engineering construction, vertical installation of power cables is a common scenario, such as in high-rise buildings, cable wells, and utility poles, where power cables need to be laid vertically. Currently, existing vertical installation methods for power cables mostly use simple bracket clamps, which have several shortcomings: First, the traction force during vertical cable installation is difficult to control, easily leading to cable surface wear and affecting cable lifespan. Second, the fixing structure of traditional installation devices is relatively simple, unable to flexibly adjust the clamping force according to cable specifications, easily resulting in problems such as loose clamping causing cable swaying, or excessive clamping damaging the cable sheath. Third, the overall stability of the installation device is insufficient; over long-term use, it is prone to loosening and displacement due to the cable's own weight or external vibrations, posing safety hazards. Fourth, the installation operation is cumbersome, requiring multiple construction workers to work together, resulting in low construction efficiency and inconvenient subsequent maintenance.
[0003] In view of the deficiencies in the prior art, the present invention proposes a power cable vertical installation device with reasonable structure, convenient operation, firm fixation and effective protection of the cable, so as to solve the shortcomings of the prior art.

[0010] The drive structure includes a cover, a drive tube rotatably connected to the cover, a gear set connected to a gear assembly, a drive gear meshing with the drive gear, and the drive gear connected to a drive roller via a shaft.
[0011] As a preferred embodiment of the vertical installation device for power cables described in this invention, the installation structure main body is provided in multiple ways, the distance between adjacent installation structure main bodies is less than 2m, and a reinforced bracket is required every 3 units.
[0012] In a preferred embodiment of the power cable vertical installation device of the present invention, the rotating grooves are provided in multiple ways, evenly distributed at the bottom and top of the inner cavity of the main body of the installation structure. The drive roller is rotatably connected to the rotating grooves through a shaft, and the top shaft extends to the outside of the main body of the installation structure. The position where the drive roller contacts the cable is provided with anti-slip texture.
[0013] As a preferred embodiment of the vertical installation device for power cables according to the present invention, the wedge-shaped grooves are provided in multiple ways, evenly distributed on the top and bottom of the inner cavity of the main body of the installation structure, and the cross-section is trapezoidal. Guide blocks are provided on the outer walls of both sides of the wedge-shaped clamping blocks. The guide blocks are located in the inner cavity of the sliding groove. There are four wedge-shaped clamping blocks, and the four wedge-shaped clamping blocks are combined to form a cable clamping groove. A rubber pad layer is provided on the inner wall of the cable clamping groove.
[0014] In a preferred embodiment of the power cable vertical installation device of the present invention, the installation structure is located at the top and bottom of the back of the main body of the installation structure, and the main body of the installation structure is fixedly connected to the slider by fixing screws, and limit blocks are provided at both ends of the slide rail.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0028] This invention provides the following technical solution: a vertical installation device for power cables. During use, this invention achieves mechanical traction of the cable through the cooperation of a drive structure and a drive roller, reducing the labor intensity of construction workers and improving the efficiency of vertical cable installation. Simultaneously, the anti-slip texture on the surface of the drive roller prevents slippage during traction, and the multi-point guidance of the rotating groove ensures that the cable remains vertical during traction, reducing cable surface wear and extending cable service life.
[0029] The wedge-shaped blocks, wedge-shaped grooves, and reset structure work together to automatically clamp and release cables. The cable clamp formed by the combination of four wedge-shaped blocks can accommodate cables of different specifications, offering strong versatility. The cable self-locking function works by using friction to move the wedge-shaped blocks downwards as the cable moves, clamping the cable and preventing it from slipping out. The rubber padding on the inner wall of the cable clamp effectively protects the cable sheath, preventing clamping damage and enhancing clamping stability to prevent cable swaying.
[0030] The mounting structure 200 uses a sliding cooperation between a slider and a slide rail, which allows for flexible adjustment of the lateral position of the main mounting structure 100 to adapt to different installation scenarios. The spacing of multiple main mounting structure 100s and the addition of reinforced brackets can effectively distribute the weight of the cables, improve the overall stability and load-bearing capacity of the device, prevent loosening or displacement after long-term use, and reduce safety hazards.
[0031] Figures 1-6 The diagram shown is a structural schematic of a first embodiment of a vertical installation device for power cables according to the present invention. Please refer to [link / reference]. Figures 1-6 This embodiment of a power cable vertical installation device includes a main installation structure 100, an installation structure 200, and a drive structure 300. These structures work together to achieve the vertical installation, fixation, and traction of the power cable. The specific structure, connection relationship, and working principle of each structure are as follows: The main mounting structure 100 is the core load-bearing component of the device, used to accommodate, guide, and clamp the power cable. It is made entirely of high-strength aluminum alloy, a material known for its light weight, high load-bearing capacity, corrosion resistance, oxidation resistance, and good processing performance. This material effectively reduces the weight of the device itself, facilitating installation and transportation, while also withstanding the cable's weight and external vibrations, preventing deformation and breakage during long-term use. The main mounting structure 100 has a rectangular parallelepiped shape, with a length of 300-500mm, a width of 200-300mm, and a height of 150-250mm. The specific dimensions can be adjusted according to the cable specifications and installation scenario.
[0032] The main body 100 of the mounting structure has a cable groove 110, a rotating groove 120, and a wedge-shaped groove 130 inside. The three work together to respectively accommodate, guide, and clamp the cable. The specific structure is as follows: 1. Cable Tray 110: The cable trough 110 is located in the center of the inner cavity of the main body 100 of the installation structure. It has a cylindrical structure with a diameter of 50-200mm. It can be adapted to the cross-sectional diameter of the cable to ensure that the cable can pass through smoothly, while avoiding excessive friction between the cable and the inner wall of the cable trough 110. The two ends of the cable trough 110 are provided with a chamfered structure with a chamfer angle of 45° to facilitate the insertion and exit of the cable and reduce wear on the cable surface.
[0033] 2. Rotating Grooves 120: Multiple rotating grooves 120 are provided, evenly distributed at the bottom and top of the inner cavity of the mounting structure body 100, and symmetrically distributed on both sides of the cable trough 110. Preferably, each mounting structure body 100 has four rotating grooves 120, divided into two groups of two, located at the top and bottom of the cable trough 110 respectively. The center lines of the two groups of rotating grooves 120 are parallel to each other and perpendicular to the center line of the cable trough 110, ensuring multi-point guidance and traction of the cable. The rotating groove 120 has a cylindrical structure with a diameter of 80-120mm and a depth of 50-80mm. The inner wall of the rotating groove 120 is provided with a wear-resistant coating made of polytetrafluoroethylene (PTFE), which has good wear resistance and lubricity, reducing friction between the drive roller 121 and the inner wall of the rotating groove 120, and extending the service life of both the drive roller 121 and the rotating groove 120.
[0034] A drive roller 121 is installed within the rotating groove 120. The drive roller 121 cooperates with the drive structure 300 to provide power for vertical cable traction, reducing friction between the cable and the main body 100 of the mounting structure and preventing cable surface wear. The drive roller 121 is made of rubber, which has good elasticity and wear resistance, effectively increasing friction with the cable and preventing slippage during traction. It also acts as a buffer, reducing damage to the cable sheath. The diameter of the drive roller 121 is 70-110mm, and its length is 50-80mm, matching the depth of the rotating groove 120. The surface of the drive roller 121 is provided with anti-slip textures 122, which are evenly distributed in a ring, with a depth of 2-3mm and a width of 5-8mm. These textures further increase friction between the drive roller 121 and the cable, ensuring smooth and reliable traction.
[0035] The drive roller 121 is rotatably connected to the rotating groove 120 via a shaft made of high-strength stainless steel, with a diameter of 20-30mm and a length of 100-150mm. Both ends of the shaft are connected to the inner wall of the rotating groove 120 via bearings. These bearings are deep groove ball bearings, providing excellent rotational performance and load-bearing capacity, ensuring the drive roller 121 can rotate flexibly and reducing rotational resistance. The top shaft extends 30-50mm beyond the main mounting structure 100, facilitating connection with the drive gear 340 to transmit driving force.
[0036] 3. Wedge-shaped groove 130: Multiple wedge-shaped grooves 130 are provided, evenly distributed on the top and bottom of the inner cavity of the mounting structure body 100, and located outside the rotating groove 120. Preferably, each mounting structure body 100 has four wedge-shaped grooves 130, divided into two groups of two, located on the top and bottom of the cable groove 110, symmetrically distributed with the rotating groove 120. The cross-section of the wedge-shaped groove 130 is trapezoidal, with an upper base length of 30-50mm, a lower base length of 50-70mm, and a depth of 40-60mm. The trapezoidal structure is compatible with the wedge-shaped clamping block 140, facilitating the clamping of the cable when the wedge-shaped clamping block 140 slides along the sliding groove 131, and automatically adjusting the clamping force according to the cable diameter.
[0037] The inner walls on both sides of the wedge groove 130 are provided with sliding grooves 131. The sliding grooves 131 are cuboid in shape, with a length of 40-60mm that matches the depth of the wedge groove 130, a width of 10-15mm, and a depth of 5-8mm. The inner wall of the sliding grooves 131 is provided with a lubricating coating, which can reduce the friction between the wedge block 140 and the sliding grooves 131, ensuring that the wedge block 140 can slide flexibly and avoid jamming. A wedge-shaped locking block 140 is slidably connected inside the slide groove 131. The shape of the wedge-shaped locking block 140 is adapted to the shape of the wedge-shaped groove 130 and has a trapezoidal structure. Guide blocks are provided on both outer walls of the wedge-shaped locking block 140. The guide blocks have a cuboid structure and their dimensions are adapted to the slide groove 131. The width is 8-13mm and the depth is 3-6mm. The guide blocks are located in the inner cavity of the slide groove 131 and can guide the sliding of the wedge-shaped locking block 140, so as to avoid the wedge-shaped locking block 140 from deviating or getting stuck during the sliding process, and ensure the smooth and reliable clamping action.
[0038] There are four wedge-shaped clamps 140, and the four wedge-shaped clamps 140, when combined, form a cable clamping groove 141. The cable clamping groove 141 has a circular structure and is used to accommodate and clamp the cable. The circular structure is adapted to the shape of the cable, which can ensure that the cable is subjected to uniform force and avoid damage to the cable sheath due to excessive local force. The combination of the four wedge-shaped clamps 140 can accommodate cables of different specifications. When the cable diameter is small, the wedge-shaped clamps 140 slide downward along the slide groove 131, and the diameter of the cable clamping groove 141 decreases, thereby clamping the cable. When the cable diameter is large, the wedge-shaped clamps 140 slide upward along the slide groove 131, and the diameter of the cable clamping groove 141 increases, adapting to the size of the cable and effectively improving the versatility of the device.
[0039] A rubber pad 142 is provided on the inner wall of the cable clamp 141. The rubber pad 142 is made of nitrile rubber, which has good elasticity, wear resistance and insulation. The thickness is 2-3mm. The rubber pad 142 is fixedly connected to the inner wall of the cable clamp 141 by an adhesive. The adhesive is a high-strength epoxy resin adhesive, which is firmly bonded and not easy to fall off. The rubber pad 142 has good elasticity and cushioning effect, which can prevent damage to the cable sheath during the clamping process of the wedge-shaped clamp 140, and at the same time further increase the clamping friction, improve the clamping firmness and prevent the cable from shaking.
[0040] A reset structure 150 is installed at the bottom of the wedge-shaped clamp 140. The reset structure 150 is used to reset the wedge-shaped clamp 140, ensuring the reliability of the clamping action. The reset structure 150 is composed of a high-strength stainless steel spring and a guide rod, with a diameter of 5-8mm, a length of 30-40mm, and an elastic coefficient of 10-15N / mm. One end of the reset structure 150 is fixedly connected to the bottom of the wedge-shaped clamp 140, and the other end is fixedly connected to the inner wall of the bottom of the wedge-shaped groove 130. The fixing method is welding to ensure a firm connection and prevent it from falling off. When the cable is inserted into the cable clamp groove 141, the cable exerts upward pressure on the wedge-shaped clamp 140, pushing the wedge-shaped clamp 140 to slide upward along the slide groove 131, and the reset structure 150 is stretched. When the cable is pulled to the designated position and the driving force is released, the reset spring resets under the action of elastic force, pushing the wedge-shaped clamp 140 to slide downward along the slide groove 131, realizing automatic clamping of the cable. The operation is convenient and requires no additional manual operation.
[0041] The mounting structure 200 is used to fix the entire device to a wall, column, or other mounting surface to ensure the stability of the device. It includes a slider 210, a slide rail 220, a fixing block 230, and a limiting block 221. The components work together to fix the main body 100 of the mounting structure and adjust its height. The specific structure is as follows: 1. Slider 210: Slider 210 is made of high-strength aluminum alloy, the same material as the main body 100 of the mounting structure, ensuring the consistency and stability of the overall structure. Slider 210 has a rectangular shape, with a length of 100-150mm, a width of 50-80mm, and a height of 30-50mm. Four screw holes, evenly distributed at the four corners of slider 210, are provided on the top of slider 210 for fixing to the main body 100 of the mounting structure. The bottom of slider 210 has a groove that matches the dimensions of slide rail 220, ensuring a tight fit and smooth sliding without loosening or shifting.
[0042] 2. Slide Rail 220: The slide rail 220 is made of channel steel, with a grade of 10#-16#. The specific grade can be selected according to the load-bearing requirements of the device. The length of the slide rail 220 is set according to the vertical installation height of the cable, generally 3-10m. The cross-section of the slide rail 220 is a "U" shaped structure with the opening facing upwards. The inner wall of the slide rail 220 is coated with a lubricating coating to reduce friction between the slider 210 and the slide rail 220, ensuring that the slider 210 can slide flexibly and facilitate the adjustment of the height of the main body 100 of the installation structure. Fixing blocks 230 are provided at both ends of the slide rail 220. The fixing blocks 230 are made of steel plate with a thickness of 10-15mm, a length of 150-200mm, and a width of 80-120mm. Four bolt holes are evenly distributed at the four corners of the fixing blocks 230. The diameter of the bolt holes is 12-16mm, used for fixing to the wall, column, or other mounting surface by fixing bolts 240.
[0043] The fixing block 230 is connected to the wall via fixing bolts 240. The fixing bolts 240 are expansion bolts, with a model number of M12-M16 and a length of 80-120mm. The appropriate length of expansion bolt is selected based on the material of the mounting surface (e.g., concrete, brick wall) to ensure the secure installation of the slide rail 220, thereby guaranteeing the stability of the entire device. The installation depth of the expansion bolts is not less than 60mm, and they must be tightened after installation to ensure a tight fit between the fixing block 230 and the mounting surface, without any loosening.
[0044] 3. Limiting Block 221: Limiting blocks 221 are provided at both ends of the slide rail 220. The limiting blocks 221 are made of high-strength aluminum alloy, compatible with the materials of the slider 210 and the slide rail 220. The limiting blocks 221 have a cuboid shape, with a length of 50-80mm, a width of 80-120mm, and a height of 30-50mm. The limiting blocks 221 are fixedly connected to both ends of the slide rail 220 by welding, ensuring a firm weld and preventing them from easily falling off. The limiting blocks 221 restrict the sliding range of the slider 210, preventing it from detaching from the slide rail 220 during sliding, ensuring safety during installation and adjustment. They also serve a positioning function, facilitating the adjustment of the slider 210's position by construction personnel, ensuring that the spacing between adjacent installation structure main bodies 100 meets requirements.
[0045] The mounting structures 200 are located at the top and bottom of the back of the main mounting structure 100, arranged symmetrically. Each main mounting structure 100 corresponds to two mounting structures 200, located at the top and bottom of the back respectively. This symmetrical arrangement ensures that the main mounting structure 100 is subjected to uniform force, avoiding tilting or loosening of the device due to uneven force, and improving installation stability. The main mounting structure 100 and the slider 210 are fixedly connected by fixing screws. The fixing screws are high-strength bolts, model M10-M12, with a length of 20-30mm. The fixing screws pass through the connecting ears on the back of the main mounting structure 100 and the screw holes on the slider 210, and are tightened with nuts. The connection method is simple and reliable, easy to install and disassemble, and convenient for subsequent maintenance. The connecting ears on the back of the main mounting structure 100 are fixedly connected to the main mounting structure 100 by welding. The connecting ears are 8-10mm thick, 100-150mm long, and 50-80mm wide, ensuring connection strength and being able to withstand the weight of the main mounting structure 100 and the cable.
[0046] The drive structure 300 provides power for cable traction, reducing the labor intensity of construction workers and improving construction efficiency. It includes a housing 310, a drive tube 320, a gear set 330, and a drive gear 340. The components work together to transmit driving force and rotate the drive roller 121. The specific structure is as follows: 1. Cover 310: Cover 310 protects the internal transmission components, preventing dust, debris, rainwater, etc., from entering and affecting the transmission effect. It also prevents workers from accidentally touching the transmission components, improving safety. Cover 310 is made of engineering plastic, which is lightweight, corrosion-resistant, has good insulation, and is easy to process. Cover 310 has a rectangular shape, with a length of 150-200mm, a width of 100-150mm, and a height of 80-120mm. A maintenance cover is located on the top of cover 310, which is fixed to cover 310 with screws, facilitating easy access and maintenance of the internal transmission components. The cover 310 is located on the top of the mounting structure body 100 and is fixedly connected to the mounting structure body 100 by screws. There are 4 screws, which are evenly distributed at the four corners of the cover 310 to ensure a firm connection and prevent it from falling off. The reasonable installation position facilitates the connection between the drive structure 300 and the drive roller 121, while avoiding interference to the drive structure 300 during the cable installation process.
[0047] 2. Drive tube 320: The drive tube 320 is used to connect to an external drive device (such as a motor or hand crank) to transmit driving force to the gear set 330. The drive tube 320 is made of high-strength stainless steel, with a diameter of 30-40mm and a length of 100-150mm. One end of the drive tube 320 penetrates through the housing 310 and extends to the outside of the housing 310, with an extension length of 50-80mm. This end is provided with a connection interface, which uses a threaded connection for easy fixed connection with the external drive device. The other end of the drive tube 320 is located in the inner cavity of the housing 310 and is fixedly connected to the gear set 330 using a key connection to ensure a firm connection, effectively transmit driving force, and prevent slippage. The drive tube 320 is rotatably connected to the housing 310, and a bearing is provided at the connection point. The bearing is a deep groove ball bearing, which has good rotational performance and sealing performance, ensuring that the drive tube 320 can rotate flexibly while preventing dust and debris from entering the inner cavity of the housing 310.
[0048] 3. Gear Set 330: Gear set 330 is used to transmit driving force, adjust speed, and adapt to different traction speed requirements. Gear set 330 is located inside the housing 310 and connected to the mounting structure body 100 via a shaft. The shaft is made of high-strength stainless steel, with a diameter of 20-30mm and a length of 80-100mm. Both ends of the shaft are connected to the housing 310 and the mounting structure body 100 via bearings, ensuring that gear set 330 can rotate flexibly and reducing rotational resistance. Gear set 330 consists of multiple gears that mesh with each other. The preferred number of gears is 2-4, and the specific number can be set according to the speed adjustment requirements. The gears are made of high-strength alloy steel, possessing good wear resistance and load-bearing capacity. The gear module is 2-3mm, and the number of teeth is 20-30, ensuring the transmission accuracy and stability of gear set 330.
[0049] 4. Drive Gear 340: Drive gear 340 meshes with gear set 330 and is used to transmit the driving force transmitted by gear set 330 to drive roller 121. Drive gear 340 is made of high-strength alloy steel, the same material as gear set 330. The module of drive gear 340 is matched with that of gear set 330, which is 2-3mm, and the number of teeth is 15-25. Drive gear 340 is connected to drive roller 121 via a shaft. The shaft and drive gear 340 are connected by a key, and the shaft and drive roller 121 are connected by welding to ensure a firm connection, effectively transmit driving force, and avoid slippage. The rotation direction of drive gears 340 on the same side is consistent to ensure that multiple drive rollers 121 rotate synchronously. This avoids problems such as uneven cable stress, twisting, and wear caused by inconsistent rotation speeds of drive rollers 121, ensuring a smooth and reliable cable traction process.
[0050] The working principle of the drive structure 300 is as follows: The external drive device (such as a hand crank or motor) is fixedly connected to the connection interface of the drive tube 320. When the external drive device is started, the drive tube 320 is rotated. The drive tube 320 drives the gear set 330 to rotate. The gear set 330 drives the drive gear 340 to rotate through meshing. The drive gear 340 drives the drive roller 121 to rotate through the shaft. The drive roller 121 drives the cable to move up or down through the friction between the anti-slip texture 122 on its surface and the cable, thereby realizing the vertical traction of the cable. The entire transmission process is smooth and reliable, and the driving force transmission efficiency is high. It can effectively reduce the labor intensity of construction personnel and improve construction efficiency.
[0051] Overall coordination and supplementary instructions for the device: 1. Arrangement of the main installation structure 100: Multiple main installation structures 100 are provided, with a spacing of less than 2m between adjacent main installation structures 100, preferably 1.5-1.8m. This spacing effectively distributes the cable's weight, preventing sagging and deformation due to excessive span, while also ensuring stability during cable traction and preventing cable deviation and bending. Furthermore, a reinforced bracket is required every three main installation structures 100. The reinforced bracket is made of angle steel, with a model ranging from 50×50×5mm to 80×80×8mm. The specific model can be selected according to the load-bearing requirements. One end of the reinforced bracket is fixedly connected to the slide rail 220 by welding, and the other end is fixedly connected to the wall, column, or other mounting surface using expansion bolts. The reinforced bracket further enhances the overall load-bearing capacity and stability of the device, preventing loosening and displacement during long-term use and reducing safety hazards.
[0052] 2. Supplement to the reset structure 150: In addition to the reset spring and guide rod mentioned above, the reset structure 150 can also use a reset spring. The reset spring is made of high-strength spring steel with a thickness of 1-2mm, a width of 10-15mm, and a length of 30-40mm. One end of the reset spring is fixedly connected to the bottom of the wedge-shaped block 140, and the other end is fixedly connected to the inner wall of the bottom of the wedge-shaped groove 130. Its working principle is the same as that of the reset spring. The appropriate reset structure 150 can be selected according to the actual use requirements.
[0053] 3. Adaptation to External Drive Devices: The drive tube 320 is compatible with various external drive devices. When the cable specification is small, a hand-cranked device can be used as the external drive device, which is convenient to operate and requires no additional power supply. When the cable specification is large and the weight is heavy, a motor can be used as the external drive device. The motor power is 0.5-1.5kW, and the speed is 100-200r / min, which can effectively improve traction efficiency and reduce labor intensity. The motor and the drive tube 320 are connected by a coupling to ensure stable transmission of driving force.
[0054] 4. Corrosion protection of the device: To extend the service life of the device and adapt to different installation environments (such as outdoor and humid environments), all metal parts of the device are subjected to corrosion protection treatment. The corrosion protection method is hot-dip galvanizing, and the thickness of the hot-dip galvanized layer is 80-100μm, which has good anti-corrosion and anti-rust properties, effectively extending the service life of the device and reducing maintenance costs.
[0055] Installation and usage process of the device: 1. Installation preparation: First, clean the installation site to ensure that the installation surface is flat, clean, and free of debris and obstacles. Based on the vertical installation height of the cable (5m in this embodiment), determine the installation position of the slide rail 220 and mark the installation points of the fixing block 230, ensuring that the slide rail 220 is installed vertically and securely. Prepare the necessary tools and components, including expansion bolts, fixing screws, wrenches, screwdrivers, hand cranks, etc.
[0056] 2. Slide Rail Installation: Place the slide rail 220 in the preset installation position and adjust its level. Align the fixing block 230 with both ends of the slide rail 220, and fix the fixing block 230 to the concrete wall using M14 expansion bolts. After installing the expansion bolts, tighten them with a wrench to ensure that the fixing block 230 is tightly fitted to the wall without any looseness. According to the spacing requirements, install the reinforced bracket on the slide rail 220, welding one end to the slide rail 220 and fixing the other end to the wall using M12 expansion bolts. Apply rust-proof treatment to the welded joint.
[0057] 3. Device Assembly: Slide the slider 210 onto the slide rail 220. Adjust the positions of the six sliders 210 according to the 1.8m spacing requirement between adjacent mounting structure bodies 100, ensuring the sliders 210 are evenly and accurately positioned. Align the connecting ears on the back of the mounting structure body 100 with the sliders 210, and securely connect the mounting structure body 100 and sliders 210 using M11 high-strength bolts. Tighten the bolts to ensure the mounting structure body 100 is vertical, stable, and without tilting. Fix the cover 310 of the drive structure 300 to the top of the mounting structure body 100 using M8 screws. Then, install the gear set 330, drive gear 340, and drive tube 320 inside the cover 310, ensuring smooth connection and flexible transmission. Finally, cover the inspection cover and tighten it with screws.
[0058] 4. Cable Installation: In this embodiment, the installed power cable has a cross-sectional diameter of 80mm, which is compatible with the dimensions of the cable trough 110 and the cable clamp 141. The power cable is inserted into the cable trough 110 of the bottom mounting structure 100, passing through each cable trough 110 of the mounting structure 100 in sequence, ensuring that the cable passes through the cable clamp 141 and is in close contact with the drive roller 121. The hand crank is fixedly connected to the threaded interface of the drive tube 320. Rotating the hand crank causes the drive tube 320 to rotate, which in turn drives the gear set 330 to rotate. The gear set 330 drives the drive gear 340 to rotate, which in turn drives the drive roller 121 to rotate. The drive roller 121, through the friction between its surface anti-slip texture 122 and the cable, pulls the cable upwards. During the pulling process, the construction personnel need to observe the cable's pulling status to ensure that the cable remains vertical, without deviation or bending. If deviation occurs, the cable position should be adjusted promptly.
[0059] 5. Cable Fixing: After the cable is pulled to the specified height (5m in this embodiment), stop rotating the hand crank and release the drive tube 320. Under the elastic force of the reset structure 150, the wedge-shaped blocks 140 slide upward along the slide groove 131. The cable clamping groove 141 formed by the four wedge-shaped blocks 140 clamps the cable securely. The clamping force is moderate to ensure that the cable does not shake or loosen, while avoiding damage to the cable sheath. Check the cable fixing status. If the clamping is too loose or too tight, adjust the position of the wedge-shaped blocks 140 to ensure a firm and reliable clamping.
[0060] 6. Subsequent Maintenance: The device should be inspected monthly, primarily checking the connections of all components, including fixing screws, expansion bolts, gear set 330, drive roller 121, etc. Loose screws should be tightened promptly to ensure secure connections. The transmission of the drive structure 300 should be checked. If jamming or abnormal noise is observed, the inspection cover should be opened immediately to check the gear set 330 and bearings. Lubricating oil (lithium-based grease) should be added if necessary to ensure smooth transmission. The cable's fixation and surface condition should be checked. If loose cables or worn sheaths are found, adjustments and repairs should be made promptly. To adjust or replace the cable, simply press down on the wedge-shaped locking block 140 to compress the reset structure 150, releasing the cable clamp 141. The cable can then be pulled to adjust or remove it; the operation is convenient.
