[0002] Aerial work platforms are widely used types of aerial work machinery, significantly improving the efficiency and safety of high-altitude construction. The turntable on existing aerial work platforms, as the core functional integration carrier, must simultaneously support components such as the power system, hydraulic system, counterweight structure, and control modules. Its layout design directly affects the platform's operational efficiency and stability. Traditional aerial work platform turntable layouts have the following drawbacks:

[0003] Low space utilization and scattered layout: Early platforms mostly adopted a chassis + turntable split layout, with the power system, hydraulic components and counterweight structure scattered on both sides of the chassis, resulting in extremely low space utilization and difficulty in adapting to the needs of relatively narrower site operations.

[0004] Therefore, how to solve the problems of space utilization and stability through the zoning optimization and functional integration of the turntable layout has become a key direction for the research and development of aerial work platforms. Utility Model Content

Detailed Implementation

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 9 As shown, this embodiment of the utility model provides a turntable layout structure for an aerial work platform, wherein the turntable 100 is rotatably mounted on the aerial work platform (e.g., Figure 9 (As shown); the upper part of the turntable 100 is divided into several areas, which include at least the first area 1, the second area 2, the third area 3, and the fourth area 4 (as shown). Figure 2 ).

[0034] The first area 1 is located on the front right side of the turntable 100. A first bracket 11 is installed in the first area 1, and two battery modules 12 are stacked on the first bracket 11. The second area 2 is located on the rear right side of the turntable 100. A second bracket 21 is installed in the second area 2. An engine 22 and an intake system located next to the engine 22 are installed on the second bracket 21. The third area 3 is located at the rear end of the turntable 100. A counterweight structure 31 is installed in the third area 3. The fourth area 4 is located on the left side of the turntable 100. An assembly frame 41 is installed in the fourth area 4. A hydraulic oil tank 42 is installed at the rear end of the assembly frame 41. An oil cooling device 43 is installed at the front end of the assembly frame 41. A fuel tank 44 is also installed on the assembly frame 41 between the hydraulic oil tank 42 and the oil cooling device 43. A lower control box 45 is also fixedly installed on the left side of the oil cooling device 43.

[0035] The 100-degree turntable layout of this aerial work platform achieves the integration and compact layout of various functional modules through a partitioned design.

[0036] The battery modules 12 (double-battery stacked) and the engine 22 and intake system are respectively arranged in the front and rear areas on the right side (area 1 and area 2). The battery modules 12 provide electric power to power electrical equipment such as the lower control box 45. The engine 22 serves as the power source to drive the aerial work platform. The counterweight structure 31 in the third area 3 at the rear of the turntable 100 balances and offsets the load of the working devices (such as telescopic booms and work buckets) at the front of the turntable 100, ensuring the stability of the platform during operation. This stacked arrangement of battery modules 12 differs from the arrangement of batteries on both sides of the turntable 100 on most pure electric aerial work platforms, effectively increasing the battery arrangement space and optimizing the battery fixing method.

[0037] The assembly frame 41 in the fourth area 4 on the left integrates a hydraulic oil tank 42, a fuel tank 44, and an oil cooling device 43. The hydraulic oil tank 42 provides the hydraulic power source for the boom extension and retraction of the aerial work platform. The oil cooling device 43 dissipates heat from the circulating hydraulic oil to prevent the system from overheating. The fuel tank 44 supplies fuel to the engine 22 to ensure energy supply. The lower control box 45 (located to the left of the oil cooling device 43) serves as the control module, receiving operating commands and coordinating the linkage between the power system, the hydraulic system, and the rotating mechanism of the turntable 100.

[0038] In summary, by using a partitioned layout, core modules such as power, electrical energy, counterweight, and hydraulics are compactly integrated into the turntable 100, reducing the overall platform footprint and making it suitable for narrower working environments. The oil cooling device 43 is integrated close to the hydraulic / fuel system, shortening pipeline length and improving heat dissipation efficiency.

[0039] In some practical applications, refer to Figures 1 to 3As shown, the second bracket 21 is rotatably connected to the turntable 100 via a pivot. The engine 22 is connected to the second bracket 21 via a damper device to buffer the vibrations generated by the engine 22 (for example, the damper device uses elastic elements, such as shock-absorbing rubber, springs, etc., to absorb the high-frequency vibrations of the engine 22 during operation). Specifically, the rotation angle between the second bracket 21 and the turntable 100 is at least 39° (in actual use, 39° is generally sufficient).

[0040] When the engine 22 needs to be inspected, the second bracket 21 can be rotated outward at a certain angle so that the engine 22 can be rotated out of the area behind the right side of the turntable 100, leaving the original compact layout space, providing maintenance personnel with a larger operating space, and facilitating the disassembly and maintenance of the engine 22 body, intake system and surrounding components.

[0041] In some practical applications, refer to Figure 1 and Figure 4 As shown, the air intake system includes an air filter 23 and an air intake pipe. The air filter 23 is connected to the first end of the air intake pipe, and the air intake port of the engine 22 is connected to the second end of the air intake pipe.

[0042] Specifically, the intake pipe is composed of a first flexible hose 24, a connecting pipe, and a second flexible hose 26 connected in sequence. The connecting pipe is configured as a rigid pipe. The connecting pipe has a horizontally arranged horizontal pipe section 251 and a vertically arranged vertical pipe section 252 connected to the horizontal pipe section 251, with the vertical pipe section 252 located above the horizontal pipe section 251. The connecting pipe is fixed to the engine 22 by a clamp structure 27. Both ends of the first flexible hose 24 are connected to the air inlet of the air filter 23 and the horizontal pipe section 251 respectively through a first clamp structure 28. Both ends of the second flexible hose 26 are connected to the air inlet of the engine 22 and the vertical pipe section 252 respectively through a second clamp structure 29.

[0043] In this embodiment, the intake system achieves efficient air intake for the engine 22 through a modular piping design. After the outside air is filtered for impurities by the air filter 23, it enters the air intake of the engine 22 in sequence through the first hose 24, the connecting pipe (horizontal pipe section 251 and vertical pipe section 252), and the second hose 26, providing clean air for combustion in the engine 22.

[0044] The first hose 24 and the second hose 26 are made of elastic material to accommodate diameter differences and installation errors between the air filter 23, the connecting pipe, and the air intake or exhaust port of the engine 22. The connecting pipe (rigid pipe) uses a horizontal and vertical L-shaped structure to plan the pipeline route. Compared with the existing intake pipe structure, which is generally laid out from above the engine 22, this intake system shortens the intake path. The first clamp structure 28 and the second clamp structure 29, together with the elastic deformation of the first hose 24 and the second hose 26, achieve a high airtight connection. Clean air enters the turbocharger of the engine 22 and is pressurized, ensuring normal air intake of the engine 22, complete combustion of fuel, and stable power output of the engine 22, avoiding insufficient torque or exhaust emissions that pollute the atmosphere.

[0045] In other practical applications, refer to Figures 5 to 8 As shown, the oil cooling device 43 includes a lower control bracket 431, an oil cooling support frame 432, a mounting bracket 433, and an oil cooler 434. The lower control bracket 431 is longitudinally mounted on the assembly frame 41, and the lower control box 45 is mounted on the left side of the lower control bracket 431; the oil cooling support frame 432 is mounted on the lower control bracket 431 and located on the right side of the lower control bracket 431; the mounting bracket 433 is mounted on the turntable 100 and arranged opposite to the oil cooling support frame 432; the oil cooler 434 is mounted on top of the oil cooling support frame 432 and the mounting bracket 433.

[0046] Specifically, the oil cooler 434 has four rectangularly distributed lugs 4341; the mounting bracket 433 has two washers 4331 installed on its upper end, and the two lugs 4341 are fixed to the two washers 4331 by bolts respectively; the oil cooling support frame 432 has a first lateral support 4321 and a second lateral support 4322 installed on it, the top surface height of the first lateral support 4321 and the second lateral support 4322 is higher than the top surface height of the oil cooling support frame 432, and the other two lugs 4341 are fixed to the top surface of the first lateral support 4321 and the second lateral support 4322 by bolts respectively.

[0047] In this embodiment, the lower control bracket 431 is longitudinally fixed to the assembly frame 41, supporting the lower control box 45 on the left side, and forming opposing supports with the mounting bracket 433 via the oil cooling support bracket 432 on the right side, jointly supporting the oil cooler 434. The top surfaces of the first lateral bracket 4321 and the second lateral bracket 4322 on the oil cooling support bracket 432 are higher than the support frame body, and cooperate with the washers 4331 on the mounting bracket 433. The four external lugs 4341 of the oil cooler 434 are fixed by bolts, forming a four-point floating installation structure. The oil cooler 434 is suspended and fixed, increasing the contact area with air and accelerating the dissipation of hydraulic oil heat. Moreover, the floating design below the oil cooler 434 also facilitates the pipeline layout of the side hydraulic oil tank 42 and fuel tank 44, improving the compactness of the overall structure.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. 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 the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
