Description

Technical Field

[0001] This utility model relates to the field of mobile cantilever cranes, and in particular to a mobile cantilever crane device. Background Technology

[0002] The core structure of a cantilever crane consists of a rotatable or fixed-angle cantilever beam and a stable mobile base (such as a wheeled chassis). An electric or pneumatic hoist is mounted on the cantilever as the lifting mechanism for vertically lifting materials. The most significant feature of this device is its excellent mobility. Unlike traditional fixed cantilever cranes that rely on overhead cranes or fixed foundations, it can be flexibly moved to different work areas, making it suitable for space-constrained, dispersed, or temporary lifting tasks.

[0003] Currently, cantilever cranes cannot be moved after installation because their structure is designed for fixed installation and requires secure anchoring to the ground or wall. During installation, the column base must be precisely connected to the pre-embedded anchor bolts, and secondary grouting must be performed to ensure stability. After installation and commissioning, the entire device forms a rigid connection with the building structure. Therefore, its location must be accurately planned before installation to ensure coverage of the required work area and avoid affecting production efficiency or increasing auxiliary handling costs due to improper placement.

[0004] However, this method has obvious drawbacks. The cantilever crane mechanism needs to destroy the poured concrete when it moves, which is a waste of time and cost. Utility Model Content

[0023] The top of the hydraulic lifting platform 2 is detachably connected to a fixing plate 4. The fixing plate 4 has multiple connecting holes 401 in the circumferential direction, and a stabilizing seat 6 is fixedly installed on the top of the fixing plate 4.

[0024] refer to Figure 2 and Figure 3 Furthermore, the top of the hydraulic lifting platform 2 is bolted to a fixing plate 4 for easy installation, disassembly, and maintenance.

A stabilizing seat 6 is located at the center of the top of the fixing plate 4, facilitating the lifting of the suspension arm mechanism by the hydraulic lifting platform 2, allowing it to be raised to a certain height and facilitating its construction.

[0025] The top opening of the telescopic cylinder 12 is provided with a first limiting ring 13.

[0026] refer to Figure 2 and Figure 3 Furthermore, a first limiting ring 13 is provided at the top opening of the telescopic cylinder 12 to limit and guide the movement stroke of the extended end of the cylinder 3. This limiting ring can effectively prevent excessive displacement or swaying of the telescopic cylinder during extension and retraction, improving operational stability. At the same time, the first limiting ring 13 can also enhance the structural connection strength, reduce wear, extend service life, ensure that the cylinder-driven fixed cone 11 is accurately and reliably inserted into the ground, and guarantee the overall safety and stability of the equipment during operation.

[0027] The mobile vehicle 1 has a lithium battery box inside its cavity, and the lithium battery box is connected to the cylinder 3 and the hydraulic lifting platform 2 via signal connection.

[0028] refer to Figure 2 and Figure 3 Furthermore, the mobile vehicle 1 is equipped with a lithium battery box inside its cavity, serving as an independent power source for the entire system and providing stable power to the cylinder 3 and hydraulic lifting platform 2. The lithium battery box is connected to the cylinder and hydraulic system via electrical wiring, enabling precise control and efficient power supply. This not only improves the mobility and operational flexibility of the equipment, eliminating the need for an external power source, but also enhances safety and environmental adaptability, making it suitable for various field or temporary construction scenarios and ensuring continuous and reliable system operation.

[0029] The top of the stabilizer 6 is detachably connected to the column 5, and the top of the column 5 is detachably connected to the cantilever 7.

The cantilever 7 is also detachably fixed to the top of the column 5, allowing adjustment of its length and angle according to actual operational needs. This modular design not only improves the equipment's flexibility and adaptability but also effectively enhances the overall structural stability.

[0031] The telescoping cylinder 12 is provided with a fixed cone 11, and a second limiting ring 14 is fixedly provided on the top of the fixed cone 11.
