Description

Technical Field

[0001] This invention relates to the field of pole-mounted energy meter box installation technology, and in particular to a pole-mounted energy meter box installation device and its usage method. Background Technology

[0002] An electricity meter, commonly known as a kilowatt-hour meter, is an instrument used to measure electrical energy, that is, to measure various electrical quantities. Taking an induction-type electricity meter as an example, its operation is based on the principle of electromagnetic induction. Inside the meter are voltage coils and current coils. When current flows through the circuit, the alternating magnetic field generated by the voltage coil and the alternating magnetic field generated by the current coil interact on an aluminum disc, causing the disc to rotate. The rotation speed of the disc is proportional to the power in the circuit. Through a series of gear transmissions, the consumed electrical energy value is ultimately displayed on the dial. For electronic electricity meters, voltage and current are sampled, and after analog-to-digital conversion and multiplication, the electrical energy is converted into a digital signal for measurement and display.

[0003] There are various installation structures for electricity meters. One common type is the pole-mounted structure, which typically includes a mounting bracket, clamps, a meter box, and the meter itself. The mounting bracket is fixed to the pole by clamps, the meter box is mounted on the bracket, and the meter is installed inside the meter box. This installation structure is frequently used for outdoor overhead lines, such as power lines in rural and suburban areas, where mounting the meter on the pole facilitates the measurement and monitoring of electrical energy in the line.

[0004] In existing technologies, the mounting brackets, clamps, meter boxes, and the overall weight of the meter are relatively large, so they often need to be disassembled for installation. This requires operators to climb up and down the column multiple times, making the operation cumbersome and labor-intensive. Summary of the Invention

[0005] To address the problem that the installation of pole-mounted energy meter boxes often requires disassembly due to the large weight of the mounting brackets, clamps, energy meter boxes, and energy meters, necessitating multiple trips up and down the pole by operators, resulting in cumbersome operations and a heavy workload, this invention provides a pole-mounted energy meter box installation device and its usage method.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A pole-mounted electricity meter box installation device includes a platform mounted on a lifting mechanism. A pair of arc-shaped guide rails are fixedly mounted on the platform. A movable frame slides along the arc-shaped guide rails. Two sliding rods slide along the movable frame. The sliding rods have threaded holes for fixing the electricity meter box. One end of each arc-shaped guide rail is fixed to the platform, and the other end extends to the outside of the platform. The sliding direction of the two sliding rods is radially along the arc-shaped guide rails. By mounting the platform on the lifting mechanism, the height can be flexibly adjusted to effectively adapt to the installation needs of electricity meter boxes at different heights, greatly reducing the difficulty and safety risks of manual climbing operations. The pair of arc-shaped guide rails on the platform, in conjunction with the slidable movable frame, allows for fine-tuning of the installation position of the electricity meter box in the horizontal direction along the arc-shaped guide rails, precisely positioning the installation location. The sliding rods slide on the moving frame and have threaded holes for fixing the electricity meter box. This design makes fixing the electricity meter box more convenient and stable. The distance between the two sliding rods can be flexibly adjusted according to the actual installation situation to fix the electricity meter box. The electricity meter box on the sliding rods can move radially along the column, ensuring accurate positioning of the column-mounted electricity meter box. This column-mounted electricity meter box installation device avoids personnel having to climb up and down the column multiple times, reducing labor and improving installation efficiency. One end of the arc-shaped guide rail is fixed to the platform, and the other end extends to the outside of the platform. This design expands the movement range of the moving frame, allowing the electricity meter box to be adjusted in a wider horizontal space, further improving the flexibility of installation positioning and facilitating operation by installers in complex environments.

[0007] Preferably, the lifting mechanism includes a base plate; rollers are installed at the corners of the bottom surface of the base plate; a lifting assembly is installed on the base plate; and a platform is installed on the lifting assembly. The rollers at the corners of the bottom surface of the base plate facilitate flexible movement of the device on the construction site, allowing for quick access to the installation location and saving transportation time and labor costs. The lifting assembly on the base plate connects to the platform, allowing for flexible height adjustment to adapt to the installation requirements of electricity meter boxes of different heights, significantly reducing the difficulty and safety risks of manual climbing operations.

[0008] Preferably, trapezoidal grooves are provided on one side of both the platform and the base plate. These trapezoidal grooves on one side of the platform and base plate facilitate securing the device to the side of the column, quickly locating the installation position of the device relative to the column, improving installation efficiency, enhancing the overall stability of the pole-mounted energy meter box installation device, making the entire pole-mounted energy meter installation process more efficient and safe, and ensuring the smooth completion of the installation work.

[0009] Preferably, the arc-shaped guide rail has a T-shaped cross-section. This T-shaped cross-section creates a more stable sliding fit with the moving frame, effectively preventing the moving frame from derailing or wobbling during sliding, and also allowing it to withstand greater lateral forces, ensuring the energy meter box remains stable during installation position adjustments.

[0010] Preferably, the movable frame is U-shaped; sliders are rotatably mounted at the corners of the bottom surface of the movable frame; and T-shaped grooves are provided on the sliders to cooperate with the arc-shaped guide rail. This U-shaped movable frame, with sliders rotatably mounted at the corners of the bottom surface and T-shaped grooves on the sliders to cooperate with the arc-shaped guide rail, makes the sliding connection between the movable frame and the arc-shaped guide rail smoother and more stable, reducing frictional resistance during movement. It also effectively prevents the movable frame from shifting or jamming during movement, ensuring the accuracy and reliability of the electricity meter box when adjusting its horizontal position.

[0011] Preferably, a round rod is provided on the top surface of the slider; the round rod is rotatably mounted on the moving frame. The slider, rotatably mounted at the bottom corner of the moving frame, has its top surface's round rod rotatably connected to the moving frame, providing a stable and flexible support structure for the slider's rotation. This makes the slider slide more smoothly on the arc-shaped guide rail and effectively avoids jamming. A cotter pin is inserted into the radial through hole at the top of the round rod. This design not only prevents the round rod from detaching from the moving frame, further ensuring the stability of the connection between the slider and the moving frame, but also facilitates disassembly and maintenance when necessary, thereby comprehensively improving the stability and convenience of the device during operation.

[0012] Preferably, the lifting assembly includes four ball screws and four nuts; the lower ends of the ball screws are rotatably mounted on the base plate; the nuts are rotatably mounted on the platform; the nuts are connected to a drive unit via a transmission unit; the drive unit can drive the nuts of the four ball screws to rotate synchronously through the transmission unit. The lower ends of the ball screws are rotatably mounted on the base plate, the nuts are rotatably mounted on the platform, and the nuts are connected to the drive unit via the transmission unit, allowing the drive unit to drive the four nuts to rotate synchronously. This design ensures that the platform maintains a consistent height during lifting, greatly improving stability and preventing platform tilting that could cause safety hazards or affect installation accuracy. Compared to traditional lifting methods, the use of ball screws enables more precise height adjustment, allowing operators to easily and accurately control the platform height according to poles of different heights, further reducing the difficulty and safety risks of manual climbing operations.

[0013] Preferably, the transmission unit includes a driving pulley and a driven pulley fixedly mounted at one end of the nut; the driven pulley is coaxial with the nut; the driving pulley is rotatably mounted in the middle of the platform bottom surface; the driving pulley is connected to the drive unit; the driving pulley is connected to the four driven pulleys via a synchronous belt. This design ensures that the drive unit can efficiently transmit power to each nut, achieving synchronous rotation of the four nuts, keeping the platform at a consistent height during lifting, greatly enhancing stability, and preventing the platform from tilting due to uneven lifting, which would affect the installation operation.

[0014] Preferably, the drive unit includes a fixed frame; the fixed frame is fixedly installed in the middle of the platform bottom surface; a motor is installed on the bottom surface of the fixed frame; the motor output end passes through the fixed frame and is keyed to the drive pulley; the fixed frame has a U-shaped cross-section. The drive unit consists of a fixed frame and a motor. The fixed frame is stably installed in the middle of the platform bottom surface, and the motor is installed on the bottom surface of the fixed frame. Its output end passes through the fixed frame and is keyed to the drive pulley. This compact and stable structure provides a strong and stable power source for the entire lifting system. The precise speed control of the motor, combined with the transmission unit consisting of the drive pulley, driven pulley, and synchronous belt, can efficiently drive the four nuts to rotate synchronously, ensuring smooth lifting of the platform. The U-shaped cross-section of the fixed frame in the drive unit provides a more stable and close-fitting space for motor installation, enhancing the stability of the connection between the motor and the fixed frame. The concave-shaped structure effectively blocks external objects from colliding with the motor, providing protection and reducing the possibility of damage to the motor due to external factors. This ensures the motor's continuous and stable power output and provides space for the synchronous belt, thereby ensuring the smooth operation of the entire lifting mechanism. This comprehensively assists in the efficient and safe installation of pole-mounted energy meters.

[0015] A method of using a pole-mounted electricity meter box installation device, comprising the following steps: S1. Move the power meter box installation device on the column to the vicinity of the column, and place the center line of the arc-shaped guide rail parallel to the center line of the column; install the power meter box on the two sliding rods; S2. Start the lifting mechanism to raise the platform to the height to be installed; S3. Push the moving frame to move along the arc-shaped guide rail, and move the power meter box on the two sliding rods to the top of the installation location; S4. Push the two sliding rods to slide and fine-tune the position of the electricity meter box to be directly above the installation location; S5. Remove the electricity meter box from the two sliding rods and install it.

[0016] The method of using this pole-mounted electricity meter box installation device can effectively avoid personnel having to climb up and down the pole multiple times, reducing labor and improving installation efficiency. At the same time, the platform height can be flexibly adjusted to adapt to different installation needs, reducing the difficulty and safety risks of manual climbing operations. Through the cooperation of arc-shaped guide rails, moving frames and sliding rods, the installation position of the electricity meter box can be accurately positioned, ensuring accurate installation and improving the reliability and stability of the installation.

[0017] As can be seen from the above technical solution, the advantages of this invention are as follows: This solution provides a pole-mounted electricity meter box installation device. By installing the platform on a lifting mechanism, the height can be adjusted to effectively adapt to the installation needs of electricity meter boxes at different heights, greatly reducing the difficulty and safety risks of manual climbing operations. A pair of arc-shaped guide rails are set on the platform, and in conjunction with a sliding moving frame, the installation position of the electricity meter box can be finely adjusted horizontally along the arc-shaped guide rails to position the installation location. The sliding rod slides on the moving frame, and the sliding rod has threaded holes for fixing the electricity meter box. This design makes fixing the electricity meter box more convenient and stable, and the distance between the two sliding rods can be flexibly adjusted according to the actual installation situation to fix the electricity meter box. It also allows the electricity meter box on the sliding rod to move radially along the column, ensuring the accurate installation position of the pole-mounted electricity meter box. This pole-mounted electricity meter box installation device avoids personnel having to climb up and down the column multiple times, reducing labor and improving installation efficiency. This solution also provides a method for using a pole-mounted electricity meter box installation device, which can effectively avoid personnel having to climb up and down the pole multiple times, reducing workload and improving installation efficiency. At the same time, the platform height can be flexibly adjusted to adapt to different installation needs, reducing the difficulty and safety risks of manual climbing operations. Through the cooperation of arc-shaped guide rails, moving frames and sliding rods, the installation position of the electricity meter box can be accurately positioned, ensuring accurate installation and improving the reliability and stability of the installation.

Detailed Implementation

[0026] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] like Figure 1-2 As shown, a pole-mounted electricity meter installation device includes a platform 1, which is mounted on a lifting mechanism. A pair of arc-shaped guide rails 2 are fixedly installed on the platform 1. A movable frame 3 is slidably installed on the pair of arc-shaped guide rails 2. Two sliding rods 4 are slidably installed on the movable frame 3. Threaded holes 401 for fixing the electricity meter box are provided on the sliding rods 4.

[0028] By mounting platform 1 on the lifting mechanism, the height can be flexibly adjusted to effectively adapt to the installation needs of electricity meter boxes at different heights, greatly reducing the difficulty and safety risks of manual climbing operations. A pair of arc-shaped guide rails 2 are set on platform 1, and together with the sliding moving frame 3, the installation position of the electricity meter box can be finely adjusted horizontally along the arc-shaped guide rails 2 to accurately position the installation location. The sliding rod 4 slides on the moving frame 3, and the sliding rod 4 has threaded holes 401 for fixing the electricity meter box. This design makes fixing the electricity meter box more convenient and stable, and the distance between the two sliding rods 4 can be flexibly adjusted according to the actual installation situation to fix the electricity meter box. This allows the electricity meter box on the sliding rod 4 to move radially along the column, ensuring the accurate installation position of the electricity meter box on the column. This column-mounted electricity meter box installation device avoids personnel having to climb up and down the column multiple times, reducing labor and improving installation efficiency.

[0029] like Figure 3-5As shown, trapezoidal grooves 7 are provided on one side of both platform 1 and base plate 5. One end of the arc-shaped guide rail 2 is fixedly mounted on platform 1, and the other end of the arc-shaped guide rail 2 extends to the outside of platform 1; the cross-section of the arc-shaped guide rail 2 is T-shaped, and the arc-shaped guide rail 2 includes an arc plate and a circular plate. The circular plate is fixedly mounted on the top surface of the arc plate, and the arc plate is fixed on platform 1. The lifting mechanism includes base plate 5; rollers 6 are installed at the bottom corners of base plate 5; a lifting assembly is installed on base plate 5; platform 1 is mounted on the lifting assembly. The moving frame 3 is generally U-shaped, and the moving frame 3 includes four straight rods that form a U-shape; sliders 8 are rotatably mounted at the bottom corners of the moving frame 3; T-shaped grooves are provided on sliders 8 to cooperate with the arc-shaped guide rail 2. A round rod 801 is provided on the top surface of slider 8; in one embodiment, the round rod 801 is rotatably mounted on the moving frame 3; the top end of the round rod 801 passes through the moving frame 3 and has a radial through hole; a cotter pin is provided in the radial through hole. In another embodiment, the round rod 801 is provided with an external thread. The round rod is mounted on the movable frame 3 by means of the external thread. In use, the round rod 801 is screwed in only a few turns to ensure that the round rod 801 can rotate on the movable frame 3.

[0030] The trapezoidal groove 7 on one side of platform 1 and base plate 5 not only facilitates locking onto the side of the column, allowing for quick and accurate positioning during installation and improving installation efficiency, but also provides additional support points during installation, enhancing the overall stability of the device. Rollers 6 are installed at the bottom corners of the base plate 5 of the lifting mechanism, enabling the device to move flexibly on the construction site and easily reach the installation position, reducing handling difficulties. The arc-shaped guide rail 2 on platform 1, with one end fixed to platform 1 and the other extending to the outside of platform 1, expands the movement range of the moving frame 3, facilitating adjustment of the electricity meter box position in complex environments. Its T-shaped cross-section fits tightly with the T-shaped groove on the slider 8, which is rotatably mounted at the bottom corner of the moving frame 3, ensuring smooth and stable sliding of the moving frame 3 on the arc-shaped guide rail 2 and preventing derailment or wobbling. The round rod 801 on the top surface of the slider 8 is rotatably connected to the moving frame 3, providing support for the slider 8's rotation and ensuring smoother sliding on the arc-shaped guide rail 2. The movable frame 3 is shaped like a square, which is very stable. The sliding rod 4 on it has threaded holes 401 for fixing the electricity meter box. This allows for flexible, convenient and stable fixing of the electricity meter box according to the actual installation situation. The installation position of the electricity meter box can be finely adjusted from multiple angles, which can improve the work efficiency and installation quality of pole-mounted electricity meter installation in all aspects.

[0031] The lifting assembly includes four ball screws 9; the lower ends of the ball screws 9 are rotatably mounted on the base plate 5; as shown... Figure 6As shown, the nut 10 of the ball screw 9 is rotatably mounted on the platform 1 using a bearing 17. A pressure plate 16 is installed above the bearing 17 and is bolted to the platform 1. The nut 10 of the ball screw 9 is connected to a drive unit via a transmission unit. The drive unit can drive the four nuts 10 to rotate synchronously through the transmission unit, achieving stable and precise height adjustment of the platform 1, effectively adapting to the installation requirements of poles of different heights, and greatly reducing the difficulty and safety risks of manual climbing operations. The transmission unit includes a drive pulley 12 and a driven pulley 11 fixedly mounted at one end of the nut 10. The driven pulley 11 is coaxially mounted with the nut 10. The drive pulley 12 is rotatably mounted in the middle of the bottom surface of the platform 1. The drive pulley 12 is connected to the drive unit. The drive pulley 12 is connected to the four driven pulleys 11 via a synchronous belt 13. The drive unit includes a fixed frame 14. The fixed frame 14 is fixedly mounted in the middle of the bottom surface of the platform 1. A motor 15 is mounted on the bottom surface of the fixed frame 14. The output end of the motor 15 passes through the fixed frame 14 and is keyed to the drive pulley 12. The fixed frame 14 has a U-shaped cross section and includes a mounting plate. Both ends of the mounting plate are vertically fixed with upright plates. The motor 15 is installed on the bottom surface of the mounting plate. Side plates are provided on the outside of the upright plates and are connected to the bottom surface of the platform 1 by bolts.

[0032] The lifting assembly includes four ball screws 9, the lower ends of which are rotatably mounted on the base plate 5, and the nuts 10 of the ball screws 9 are also rotatably mounted on the platform 1. The transmission unit plays a crucial role in connecting the drive unit and the nuts 10. It includes a drive pulley 12 and driven pulleys 11 fixed to one end of the nuts 10 and coaxially arranged therewith. The drive pulley 12 is mounted in the middle of the bottom surface of the platform 1, can rotate flexibly, and is connected to the four driven pulleys 11 via a synchronous belt 13. The core of the drive unit is a motor 15, which is mounted on the bottom surface of a fixed frame 14. The fixed frame 14 has a concave cross-section and is firmly fixed in the middle of the bottom surface of the platform 1. The output end of the motor 15 passes through the fixed frame 14 and is connected to the drive pulley 12 via a key.

[0033] In other alternative embodiments, the drive unit is replaced by an electric linear actuator drive unit, mainly composed of multiple electric linear actuators, a controller, a power module, etc. Each electric linear actuator corresponds to a ball screw, with one end fixed to the base plate and the other end connected to the nut of the ball screw. The controller can control the synchronous movement of multiple electric linear actuators, and the power module supplies power to the electric linear actuators and the controller. During operation, the controller issues a command, and the motor of the electric linear actuator rotates, converting the rotational motion into linear motion through the internal screw-nut mechanism, pushing or pulling the nut of the ball screw, thereby realizing the raising or lowering of the platform. By precisely controlling the stroke and speed of each electric linear actuator through the controller, the synchronous movement of the nuts of the four ball screws is ensured, achieving smooth lifting and lowering of the platform. The price of electric linear actuators is relatively high, especially high-precision, high-thrust electric linear actuators, which may result in a higher cost for the entire drive unit than the original solution.

[0034] In other alternative embodiments, the gear transmission unit consists of a driving gear, four driven gears, and a transmission shaft. The driving gear is mounted on the output shaft of a motor (similar to motor 15 in the original drive unit) and located in the center of the bottom surface of platform 1. The four driven gears are respectively fixed to one end of the nut 10 of the four ball screws 9 and are coaxial with the nut 10. The driving gear meshes with the four driven gears. During operation, the motor starts, driving the driving gear to rotate. The driving gear transmits power to the four driven gears through meshing with them. Since the driven gears are coaxial with the nut 10, they drive the nut 10 to rotate synchronously. The rotation of the nut 10 drives the ball screws 9 to move up and down on the base plate 5, achieving smooth lifting and lowering of platform 1. The gears require high manufacturing precision, and the processing cost is relatively expensive, especially for high-precision gears. The cost of the entire gear transmission unit may be higher than that of a synchronous belt transmission unit.

[0035] During operation, the motor 15 starts, and its output rotation drives the drive pulley 12 to rotate. The drive pulley 12 transmits power to the four driven pulleys 11 via the synchronous belt 13. Since the driven pulleys 11 are coaxial with the nut 10, they in turn drive the nut 10 to rotate synchronously. The rotation of the nut 10 drives the ball screws 9 to move up and down on the base plate 5, achieving smooth lifting and lowering of the platform 1. This structural design brings many beneficial effects. First, the four ball screws 9, in conjunction with the transmission and drive units, ensure that the platform 1 maintains a consistent height during lifting and lowering, greatly improving stability and preventing the platform from tilting due to uneven lifting and lowering, which would affect the installation of the electricity meter. Second, the U-shaped mounting bracket 14 provides a stable and protective installation space for the motor 15. The two sides can block external objects from colliding with the motor 15, reducing the risk of motor damage and ensuring stable power output from the motor. Furthermore, the design of the entire lifting mechanism enables precise height adjustment. Operators can easily and accurately control the height of platform 1 according to the poles of different heights, further reducing the difficulty and safety risks of manual climbing operations, and comprehensively assisting in the efficient and safe installation of pole-mounted energy meters.

[0036] In other alternative embodiments, the lifting assembly is replaced by a hydraulic lifting assembly, which mainly consists of a hydraulic pump station, hydraulic cylinder, piston, piston rod, oil tank, and related control valves and pipelines. During operation, the hydraulic pump station delivers hydraulic oil to the hydraulic cylinder through pipelines, pushing the piston and piston rod upwards, thereby raising the lifting platform. During descent, the hydraulic oil flows back to the oil tank via control valves, and the platform descends under its own weight. It can withstand greater weight and can be used for large equipment or simultaneous lifting operations for multiple people. The hydraulic system can precisely control flow and pressure, making the lifting process smoother, reducing swaying and vibration, and improving operational safety. Compared to some mechanically driven lifting assemblies, hydraulic lifting assemblies operate with less noise, making them suitable for environments with high noise requirements. Precise control of lifting speed and position can be achieved through various control valves to meet different operational needs. However, the hydraulic components of hydraulic lifting assemblies require high manufacturing precision and are expensive, resulting in a higher overall system cost compared to scissor lift assemblies. Hydraulic systems are more complex, requiring a higher level of technical expertise from maintenance personnel, and troubleshooting and repair are more difficult in case of malfunctions. Although hydraulic systems have sealing measures, hydraulic oil may leak after prolonged use, which can pollute the environment and affect the normal operation of the lifting components. Furthermore, hydraulic systems are bulky, inconvenient to move, and have a limited range of applications.

[0037] A method for using a pole-mounted energy meter installation device includes the following steps: Preparation phase: 1. Transportation and Positioning: Because the bottom plate 5 of the lifting mechanism is equipped with rollers 6 at the bottom corners, it can push the entire pole-mounted energy meter installation device to move it quickly and flexibly to a suitable installation position near the pole, saving transportation time and labor costs. 2. Determine the installation location: Locate the approximate location on the pole where the electricity meter box needs to be installed. Utilize the trapezoidal groove 7 on one side of the platform 1 and the base plate 5 to clamp the device onto one side of the pole. This will quickly and accurately determine the relative installation position of the device and the pole, improve installation efficiency, and enhance the overall stability of the device. 3. Install the electricity meter box: The slide rod 4 slides on the moving frame 3. Adjust the distance between the two slide rods 4 according to the actual size of the electricity meter box so that the threaded holes on the slide rod 4 for fixing the electricity meter box are aligned with the corresponding mounting holes on the electricity meter box. Then, the electricity meter box is securely fixed to the slide rod 4 through the threaded connection.

[0038] Platform lifting and lowering phase: 1. Start-up drive unit: The drive unit includes a motor 15 fixed on a mounting frame 14 at the center of the bottom surface of platform 1. The output end of the motor 15 passes through the mounting frame 14 and is keyed to the drive pulley 12. The mounting frame 14 has a U-shaped cross-section, providing a stable installation space and protection for the motor 15. 2. Transmission and Platform Lifting: The motor 15 drives the drive pulley 12 to rotate. The drive pulley 12 is connected to the driven pulley 11, which is fixed to one end of the nut 10, via a synchronous belt 13. The driven pulley 11 and the nut 10 are coaxially arranged. When the drive pulley 12 rotates, it drives the four driven pulleys 11 to rotate synchronously via the synchronous belt 13, thereby causing the nuts 10 of the four ball screws 9 connected to the driven pulleys 11 to rotate synchronously. Because the lower end of the ball screw 9 is rotatably mounted on the base plate 5, and the nut 10 is rotatably mounted on the platform 1, the rotation of the nut 10 drives the platform 1 to rise smoothly upward along the ball screw 9 until the platform 1 reaches the position that matches the predetermined installation height of the electricity meter box on the pole, at which point the motor 15 stops operating.

[0039] Electricity meter box installation location adjustment stage: 1. Coarse Horizontal Adjustment: Place the electricity meter box on the movable frame 3. The movable frame 3 is a U-shaped frame with a slider 8 rotatably mounted at its bottom corner that engages with the arc-shaped guide rail 2 on the platform 1. The slider 8 has a T-shaped groove that matches the T-shaped cross-section of the arc-shaped guide rail 2. Push the movable frame 3 to slide it on the arc-shaped guide rail 2. One end of the arc-shaped guide rail 2 is fixed to the platform 1, and the other end extends to the outside of the platform 1, expanding the movement range of the movable frame 3. This allows operators to make preliminary adjustments to the position of the electricity meter box within a larger horizontal space, bringing it closer to the accurate installation point of the electricity meter box on the pole. 2. Horizontal fine adjustment: Based on the actual situation, further finely push the moving frame 3 to slide on the arc-shaped guide rail 2 to achieve precise fine adjustment of the installation position of the power meter box along the arc-shaped guide rail 2 in the horizontal direction, thereby accurately positioning the installation position; 3. Radial adjustment: By sliding the slide bar 4, the electricity meter box is moved radially along the column to further ensure the accurate installation position of the electricity meter box and move the electricity meter box directly above the installation location.

[0040] Complete the installation and equipment removal phase: 1. Confirm installation: Remove and install the electricity meter box on slide bar 4, ensuring that the electricity meter box is installed firmly and in the correct position; 2. Device Lowering and Removal: Reverse start motor 15 drives drive pulley 12 in reverse, causing the nuts 10 of the four ball screws 9 to rotate synchronously in opposite directions via synchronous belt 13 and driven pulley 11. Platform 1 descends smoothly to the ground along the ball screws 9. Disconnect the device from the power meter box, and push the device away from the installation site via rollers 6, completing the installation of the entire pole-mounted power meter box.

[0041] During the preparation phase, the design of the rollers 6 at the corners of the base plate 5 greatly enhances the flexibility of transporting and positioning the device, significantly saving handling time and labor costs. The trapezoidal grooves 7 on the sides of the platform 1 and the base plate 5 can quickly and accurately locate the relative position of the device and the pole, not only improving installation efficiency but also enhancing the overall stability of the device. The sliding rod 4 can flexibly adjust the spacing to securely fix the power meter box, facilitating subsequent operations. During the lifting phase of the platform 1, the coordinated operation of the motor 15, the driving pulley 12, the driven pulley 11, the synchronous belt 13, and the ball screw 9 ensures that the platform 1 is raised smoothly and accurately to the predetermined height, preventing the platform 1 from tilting, ensuring installation accuracy, and reducing the risk of manual climbing. During the adjustment phase of the power meter box installation position, the cooperation between the moving frame 3 and the arc-shaped guide rail 2 allows for coarse adjustments in a larger horizontal space, precise fine adjustments along the arc-shaped guide rail 2, and radial adjustments achieved by the sliding rod 4, enabling precise positioning of the power meter box installation position from all directions and multiple angles. After completing the installation and removal phases, it was confirmed that the installation process ensured the stability and accuracy of the power meter box installation. The descent and removal process was smooth, and the platform 1 was lowered smoothly by the reverse control of motor 15, which facilitated and quickly completed the entire installation work. Overall, the workload was greatly reduced, and the installation efficiency and quality of the pole-mounted power meter box were significantly improved.
