Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, specifically to a high-altitude mobile work platform device. Background Technology

[0002] In the field of water conservancy engineering and dam maintenance, the safety and efficiency of high-altitude operations (such as wave wall grinding, repair, and lighting installation) have always been key concerns in the industry. Currently, for dam operations near the water surface or at height, existing technologies mainly employ traditional hanging baskets or temporary assembled work platforms. Traditional hanging baskets or temporary platforms require manual assembly, resulting in complex installation procedures and inconvenient disassembly. Furthermore, the platforms are bulky and require external hoisting equipment for movement, limiting the scope of work and making them unsuitable for large-scale continuous construction. Simultaneously, these platforms lack flexible mobility and adjustment capabilities, requiring frequent disassembly and reassembly by construction workers, severely restricting construction efficiency. To circumvent these problems, some construction companies even illegally use substandard, unsafe platforms or rely solely on safety belts, further exacerbating the risk of falls from heights.

[0003] Furthermore, while existing technologies include some designs for aerial work platforms, most are limited to single-function or specific scenario applications, lacking adaptable structures for complex environments such as dam breakwalls, and lacking the ability to be flexibly moved on-site and combined with multi-level operating platforms. Therefore, it is necessary to design an aerial mobile work platform device suitable for dam breakwall construction to improve construction efficiency, ensure safety, and solve many problems associated with traditional hanging baskets or temporary assembled work platforms.

[0028] The high-altitude mobile work platform device of this utility model achieves its structural and functional characteristics through the combination of multiple components. The implementation method is described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, the aerial mobile work platform device includes a platform body 1, a moving device 2, and an auxiliary wheel assembly. The connection relationship, position distribution, and cooperation relationship between the components are described below.

[0030] The main body of the platform 1 includes A-type steel pipe 111, B-type steel pipe 112, first circumferential reinforcement 102, second circumferential reinforcement 104, third circumferential reinforcement 107, first step 103, second step 105, third step 108, steel ladder 109, and safety net 110. A-type steel pipe 111 and B-type steel pipe 112 are welded together to form an integral frame structure. They are arranged parallel in the vertical direction and reinforced by welding several transverse galvanized steel pipes to ensure overall rigidity. Platform 103, Platform 105, and Platform 108 are arranged sequentially from top to bottom. Platform 103 is located on top of the B-type steel pipe 112 (near the top of the wave-breaking wall). Platform 105 and Platform 108 are connected at both ends to the integral frame structure formed by the A-type steel pipe 111 and the B-type steel pipe 112, respectively. Platform 105 has a semi-circular notch on the side near the steel ladder 109 to facilitate the passage of construction personnel. Platform 105 serves as the first working platform, and Platform 108 serves as the second working platform. Circular reinforcement components 102, 104, and 107 are located above the platforms at different heights and are welded and fixed to the A-type steel pipe 111 and the B-type steel pipe 112. Their main function is to enhance the overall stability of the frame. Specifically, the first circumferential reinforcement component 102 is located above the first step 103, the second circumferential reinforcement component 104 is located above the second step 105, and the third circumferential reinforcement component 107 is located above the third step 108. These circumferential reinforcement components are evenly distributed horizontally. The steel ladder 109 is welded and fixed to the B-type steel pipe 112 and installed near the wave-breaking wall 3 on one side, for the passage of construction personnel. The protective net 110 is welded and fixed to the left and right sides of the platform's main body 1, with a mesh size of 100mm × 100mm, providing sufficient safety protection for construction personnel.

[0031] The mobile device 2 includes an electrically connected solar power generation system, a battery pack 202, an inverter 204, a motor 205, electric wheels 206, and a remote controller 207. The solar power generation system includes a solar panel 201 and a solar controller 203. The solar panel 201 is fixedly mounted on the top of the platform body 1 and connected to the solar controller 203 via wires 208. The controller converts solar energy into electrical energy and stores it in the battery pack 202. The battery pack 202 is located below the solar panel 201 and connected to the inverter 204 via wires 208. The inverter 204 is mounted below the first pedal 103 and converts direct current (DC) to alternating current (AC) before outputting it to the motor 205. The motor 205 is connected to the inverter 204 via wires 208 and drives the electric wheels 206 to rotate. Specifically, the motor 205 is bolted to the bottom of the B-type steel pipe 112, and its output shaft is coaxially connected to the electric wheels 206. The remote controller 207 is used to control the operating status of the motor device 205 and the locking function of the electric moving wheel 206. The electric moving wheel 206 has a braking mechanism, which includes a friction plate and a spring assembly. When the remote controller 207 sends a stop signal, the friction plate in the braking mechanism automatically clamps the wheel edge to complete the locking function. The outer surface of the electric moving wheel 206 has a rubber layer to increase friction and reduce vibration; the spring assembly is used to drive the friction plate to reset when the brake is released.

[0032] The auxiliary wheel assembly consists of multiple nylon auxiliary wheels 101, distributed on both sides and the top of the B-type steel pipe 112. Each auxiliary wheel 101 has a diameter of 100mm, a wheel surface width of 50mm, uses bearing type 6203, and has a hole spacing of 17mm. The auxiliary wheels 101 are welded to the B-type steel pipe 112. One row of three auxiliary wheels 101 is located near the inner side of the wave-breaking wall 3, two rows of six auxiliary wheels 101 are located near the top of the wave-breaking wall 3, and two rows of six auxiliary wheels 101 are located on the outer side of the wave-breaking wall. The placement of the auxiliary wheels 101 effectively reduces resistance during platform movement and improves platform stability.

[0033] In one specific embodiment, the second pedal 105 adopts a split folding structure, including a left pedal and a right pedal. These two parts are hinged to an integral frame formed by welding A-type steel pipes 111 and B-type steel pipes 112 of the platform body 1, respectively. In the non-use state, the left and right pedals can rotate 90° inward along the hinge axis to fold vertically, fitting snugly against the inner side of the frame for storage, reducing space occupation. In use, the left and right pedals are rotated outward to a horizontal position, so that their ends meet to form a complete operating platform. At this time, rigid fixation is achieved by the locking device 106 in the middle of the pedals. Specifically, this device includes a steel locking pin, a return spring sleeved on its outside, and a corresponding chrome-plated locking hole opened in the B-type steel pipe. Construction personnel can unlock / lock the pedals by pulling a pull ring with anti-slip texture. Specifically, the locking device 106 includes a locking pin, a return spring, and a pull ring; the pull ring is connected to an L-shaped lever, which is pivotally connected to the pedal; when the pull ring is pulled, the lever rotates around the pivot, overcoming the spring force to pull out the locking pin and unlock; after being released, the return spring pushes the locking pin into the locking hole to complete the locking. The locking device forms an integral rigid structure at the middle joint of the pedal, ensuring the stability and safety of construction personnel working in the middle area of ​​the wave wall, while the folding design adapts to the transportation and storage needs of the narrow working space of the dam.

[0034] In actual use, construction workers first ascend to platform 103 via steel ladder 109 for preliminary inspection and preparation. They can then choose to proceed to platform 205 or platform 308 to carry out specific construction work as needed. During construction, solar panels 201 continuously absorb sunlight and convert it into electrical energy, storing it in battery pack 202. Inverter 204 converts the stored DC power into AC power to power motor 205. Construction workers start motor 205 via remote control 207, driving electric wheels 206 to move the entire platform smoothly along the wave-breaking wall. During this process, auxiliary wheels 101 effectively reduce frictional resistance between the platform and the wave-breaking wall, while improving platform stability. If temporary stopping is required, construction workers can operate remote control 207 to trigger the braking mechanism, locking the electric wheels 206 to ensure the safety and reliability of the platform during construction.

[0035] The above describes the specific embodiments of this utility model. The connection relationships, positional distribution, and cooperation relationships between all components have been described in detail to ensure that those skilled in the art can fully implement the technical solution of this utility model based on the above content.

[0036] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the operating principle and implementation steps of this utility model is provided in conjunction with the accompanying drawings and specific application scenarios.

[0037] When using this aerial work platform, construction workers first ascend to the first step 103 via the steel ladder 109. The first step 103 is located near the top of the breakwater, facilitating preliminary inspection or preparation work on the top area of ​​the breakwater. At this point, workers can activate the motor 205 in the mobility device 2 via the remote control 207, driving the electric wheels 206 to move the entire platform smoothly along the breakwater. During this process, the auxiliary wheels 101 in the auxiliary wheel assembly contact the surface of the breakwater, effectively reducing frictional resistance during platform movement and improving platform stability. The auxiliary wheels 101 are distributed at different locations on the inner, top, and outer sides of the breakwater. Their nylon material and bearing design ensure that the platform will not damage the surface of the breakwater during movement and can adapt to the complex structure of the breakwater.

[0038] Once the platform is moved to the designated construction position, the construction personnel can operate the remote control 207 to trigger the braking mechanism inside the electric moving wheel 206. The friction plates in the braking mechanism automatically clamp the wheel edge, completing the locking function and ensuring the safety and reliability of the platform during construction. At this time, the construction personnel can choose to enter the second platform 105 or the third platform 108 to carry out specific construction work as needed. The second platform 105 serves as the first construction operating platform and is mainly used for grinding, repairing, or installing lights in the middle area of ​​the breakwater; the third platform 108 serves as the second construction operating platform and is used for construction in the lower area of ​​the breakwater. The multi-level platform design allows construction personnel to work simultaneously at different heights, significantly improving construction efficiency.

[0039] During construction, the solar power system continuously provides power to the platform. Solar panels 201 convert sunlight into electricity, which is then stored in a battery bank 202 via a solar controller 203. The direct current (DC) power from the battery bank 202 is converted to alternating current (AC) power by an inverter 204 and output to a motor 205 to drive the electric wheels 206. This design not only enables the platform to move autonomously but also avoids dependence on external power sources, making it particularly suitable for high-altitude operations far from power sources, such as those on dam breakwalls. Furthermore, the remote control 207 allows construction personnel to flexibly control the platform's speed and direction, further enhancing construction flexibility.

[0040] If construction workers need to adjust the position of the second step 105, this can be achieved through its split folding structure and locking device 106. The step is divided into left and right parts, which are respectively hinged to the A-type steel pipe 111 and B-type steel pipe 112 welded frames of the platform body 1 via hinges. When not in use, it can be rotated 90° inward along the hinge axis to fold vertically for storage. When in use, it is rotated outward to a horizontal position, aligning the ends of the left and right steps, at which point it is fixed by the central locking device 106. Construction workers can unlock and slide the step by pulling the pull ring; after releasing, the spring automatically pushes the locking pin into the hole to achieve rigid fixation. Simultaneously, a semi-circular notch is provided at the contact point between the step and the steel ladder 109 to ensure unobstructed passage for personnel. The overall design not only meets the multi-height operation requirements in the middle of the wave-breaking wall but also adapts to narrow construction spaces through folding storage, improving operational flexibility and safety.

[0041] The protective net 110 provides comprehensive safety protection for construction workers. The net's mesh size is 100mm × 100mm, ensuring both ventilation and preventing small tools from falling. The net effectively prevents workers from being injured by accidental falls. Furthermore, the overall frame structure of the platform's main body 1 is made of φ20 galvanized steel pipes. Type A steel pipes 111 and 112 are welded together to form a rigid frame. Ring reinforcement members 102, 104, and 107 are located above the steps at different heights and are welded to Type A and Type B steel pipes 111 and 112, evenly distributed horizontally, further enhancing the overall stability of the frame.

[0042] In actual construction, the modular design of the platform allows all components to be assembled by welding or bolting, facilitating transportation and storage. The main body of the platform is made of φ20 galvanized steel pipe, which is inexpensive and has good corrosion resistance, making it suitable for long-term use in water conservancy projects and dam maintenance. Through the combination of the above steps and principles, this utility model achieves efficient, safe, and flexible movement of the aerial work platform, solving the problems of complex installation procedures, inconvenient movement, and limited coverage of traditional hanging baskets or temporary assembled work platforms, and has broad application prospects.

[0043] In summary, the technical solution of this utility model, through innovative designs such as multi-layer pedals, solar-powered system, auxiliary wheel assembly and protective net, significantly improves construction efficiency and safety, ensuring that those skilled in the art can fully implement the technical solution of this utility model based on the above content.

[0044] In this utility model, the auxiliary wheel, locking device, solar power panel, inverter and other equipment are all mature products on the market, which can be directly purchased, installed and used. Moreover, these devices have been widely used in various fields, and those skilled in the art are familiar with their usage methods, so there is no technical threshold.

[0045] The above description is merely one embodiment of this utility model and is not intended to limit this utility model in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of this utility model's technical solution.
