Description

Technical Field

[0001] This invention belongs to the field of crawler crane hoisting and relates to an auxiliary platform for quick assembly and disassembly of booms. Specifically, it relates to an auxiliary assembly platform for a standard section of a prefabricated truss boom with a variable cross-section. Background Technology

[0002] The boom is a key load-bearing structural component for crawler cranes. To ensure sufficient lifting capacity while meeting transportation regulations, various prefabricated, variable-section truss-type standard sections have emerged on the market. These standard sections can meet the different cross-sectional requirements of crawler cranes for lifting and transportation by adjusting the boom's cross-section. However, the assembly process for these boom sections is complex during the cross-section adjustment, and proper alignment is difficult, affecting operational efficiency and consuming considerable time and effort. Furthermore, the boom sections are heavy and difficult to move, placing high demands on on-site assembly conditions.

[0003] Therefore, this invention proposes an auxiliary platform for boom assembly and disassembly, which can meet the assembly and disassembly requirements of variable cross-section boom sections, effectively reduce the manpower and material resources spent on assembly and disassembly, improve assembly and disassembly efficiency, and reduce assembly and disassembly costs.

Including fixed support one and fixed support two; The fixed support 2 includes two tracks and an outer frame; Two connecting rods are installed on one side of the outer frame; A rolling support is movably mounted at the center of the other side of the outer frame. The rolling support includes brackets on both sides and a round tube welded between the brackets. A roller is installed on the bottom wall of each of the two brackets, and the roller is movably mounted on the outer frame; A matching pin hole is provided at the connection between the bracket and the roller, and a pin for movably connecting the bracket and the roller is inserted into the pin hole.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] As shown in the figure, the boom quick assembly and disassembly auxiliary platform of the present invention drives the entire boom section by changing its own width, realizing the change of cross section and the alignment of assembly holes, without requiring too much disassembly and assembly process, making the disassembly and assembly process simple and efficient.

[0015] This invention is assembled from several legs, brackets, fixed supports, connecting rods, rolling supports 1, bases 2-2, etc., and its overall structure is as follows: Figure 1 As shown; the structural components in this invention are mainly welded from pipes and plates.

[0016] Figure 2 This is a schematic diagram of the overall structure of the rolling support 1 in this invention. The rolling support 1 includes a bracket 1-1 for placing the boom section and rollers 1-2 for rolling on the fixed support 2. The rollers 1-2 are mounted on the rolling support 1 at a specific angle via pins 6-1 to ensure the movement trajectory of the rolling support 1. The rolling support 1 is connected to the fixed support 2 via a connecting rod 5 and pins 6-2, forming a parallelogram shape that can rotate relative to it. Overall, it can move in an arc along a designed trajectory on the fixed support 2. Simultaneously, a limit block 7 is provided on the platform to prevent excessive displacement beyond the range of the track 10 in the fixed support 2. Specifically, as shown... Figure 3 As shown.

[0017] Figure 4 This is a schematic diagram of the overall structure of the fixed support 2 in this invention. The fixed support 2 is connected to the rolling support 1 via a connecting rod 2 5, and the connection method is the same as... Figure 3 The same; the rolling support 1 is simultaneously connected to the fixed support 2 via connecting rod 4, and is fixedly connected by two pins 6-3, see Figure 5 The fixed support 2 includes a bracket 2-1 and a base 2-2 for placing the boom section. Each base 2-2 can be adjusted in height by screwing in and out bolts 9 to ensure overall levelness, and is designed with a handle 8 for easy rotation. Figure 6 During transportation or storage, the connecting rod 4 can be folded up, and then connected to the fixed support 2 during operation to save space.

[0018] like Figure 7 This is a schematic diagram of the overall structure of the fixed support 2 3 in this invention. The fixed support 2 3 is connected to the fixed support 2 1 via a connecting rod 4, and the connection method is the same as... Figure 5 The fixed support 23 has a bracket 2-1 and a base 2-2 for placing the boom section, and each base 2-2 is the same Figure 6 The height of each component can be adjusted using bolt 9 to ensure overall levelness. Figure 6 The fixed support 2 3 also has a track 10 for the rolling support 1 to roll on it; the fixed support 2 3 can be designed in a folding or telescopic mode to save space during storage or transportation.

[0019] like Figure 8 The disassembly and assembly process described above illustrates the working process of this platform. Taking the following variable cross-section boom assembly process as an example, after assembling the platform into the working state, the two sectors A and B of the boom to be assembled are first placed on the brackets of the fixed support 2 and the rolling support 1, respectively. Sector B is pushed to move along the track 10 in the direction shown in the figure. At the same time, the angles of all the web members on the boom section move accordingly, thereby increasing the cross-section. Then, the remaining web members and components are assembled. When the boom changes from the working state to the transportation state, the process of the boom cross-section decreasing is the reverse of the above process, as shown in the figure. Figure 8 .

[0020] This invention solves several existing problems: 1. It meets the requirements for disassembly and assembly of variable cross-section boom sections; 2. It enables quick assembly via connecting rods, making it easier and more convenient to switch between platform working and transportation states; 3. The assembly holes of the variable cross-section boom sections can be quickly aligned, reducing hoisting requirements and improving the convenience of disassembly and assembly; 4. It is simple and easy to operate, convenient and quick, and highly safe.

[0021] The working principle of this invention is as follows: 1. The platform height can be finely adjusted by screwing in and out bolts; 2. This invention consists of fixed supports and rolling supports, etc., and utilizes the instability principle of parallelograms to facilitate cross-section adjustment; 3. In the process of adjusting the boom section cross-section, this invention only requires hoisting the fan-shaped section onto the bracket on the platform, allowing one side of the fan-shaped section to move along the track on the fixed support to the other side, so that the required joints are aligned. The whole process is convenient, quick, simple, efficient, and reliable; 4. This invention adopts a modular design, dividing the platform into multiple detachable modules for easy maintenance. Each module can also be designed as a folding or telescopic form for convenient transportation and storage; 5. The purpose of this invention is to assist in changing the cross-section of the boom section. It is not limited to the variable cross-section boom section shown in the attached figure, but can also be used for other types of variable cross-section boom sections, adapting to various boom section forms.
