This design can reduce the shaking of the equipment during transportation, reduce the impact on the fixing device, thereby prolonging the service life of the device, the elasticity of the spring ring allows the pull pin 6 and the pull claw 7 to be dynamically adjusted, adapting to the possible slight displacement or vibration during transportation, further improving the anti-vibration ability of the fixing device, the elasticity of the spring ring can be adjusted according to different load requirements, ensuring that the pull pin and the pull claw can maintain appropriate connection force during the transportation of equipment of different weights or shapes, avoiding being too tight or too loose, the design of the spring ring makes the connection between the pull pin and the pull claw more flexible, facilitating fine tuning during installation and disassembly, improving the convenience of operation;The rear end is fixedly connected with a piston rod 8, and a pull claw 7 is clamped or loosened on the support rod 3. Preferably, the pull claw 7 is a four-piece pull claw that can be elastically expanded or contracted in the radial direction. The four-piece pull claw can automatically adjust the degree of expansion or contraction according to the diameter of the support rod. The elastic design of the four-piece pull claw makes the installation and disassembly process more convenient. The pull claw is only needed to be aligned with the support rod, and the pull claw will automatically expand or contract through its own elasticity, thereby quickly completing the fixing or loosening operation. The design of the four-piece pull claw ensures that multiple contact points are formed between the pull claw and the support rod, which can uniformly distribute the load, thereby improving the stability and anti-interference ability of the fixing. The design of the four-piece pull claw makes the structure of the fixing device more compact and occupies less space, which is suitable for the transportation needs of large and heavy equipment. The piston rod 8 is provided with an elastic element 9. The two ends of the elastic element 9 are respectively abutted against the inner wall of the sleeve 4 and the annular protrusion of the piston rod 8.

The disc spring is a high-load-capacity elastic element that can withstand a large compression force. In the transportation of large and heavy equipment, the disc spring can effectively disperse the weight of the equipment, ensuring the stability of the fixing device.

The disc spring has good elastic properties and can absorb vibrations and impact forces during transportation, reducing the shaking of the equipment during transportation and reducing the impact on the fixing device and the equipment, thereby prolonging the service life of the device. The disc spring has stable elastic properties and can maintain consistent elastic performance under different loads, ensuring that the fixing device always maintains a stable fixed state during transportation. The disc spring has excellent fatigue resistance and can maintain its elastic properties during multiple compression and release processes, which is suitable for high-frequency transportation needs. The structure of the disc spring is compact and occupies less space, which is suitable for use in limited transportation space.A sealing element 10 is provided between the piston rod 8 and the sleeve 4.

The hydraulic system has high load capacity and can provide sufficient pressure to drive the action of the piston rod 8 and the pawl 7, ensuring the safe fixation of large heavy equipment. The fixing device can meet the needs of large load equipment through the hydraulic oil pressure provided by the hydraulic system, especially when transporting heavy equipment. The hydraulic system can provide stable and strong fixing force. The hydraulic system has fast response speed and can complete the clamping or loosening action of the draw pin 6 and the pawl 7 in a short time, improving the operation efficiency. The transportation bracket 2 can be installed or disassembled in a very short time through the fast response ability of the hydraulic system, reducing the transportation preparation time.

Preferably, the outer wall of the inner positioning sleeve 12 is provided with a tapered slope at the upper end. The tapered slope design enables the outer positioning sleeve 13 to automatically align with the inner positioning sleeve 12 during installation. When the outer positioning sleeve 13 is inserted into the inner positioning sleeve 12, the slope can guide the outer positioning sleeve to gradually align with the center position, reducing the difficulty of manual alignment. The design of the slope simplifies the installation process, and the operator does not need to accurately align, but only needs to align the outer positioning sleeve with the slope to easily complete the installation. The tapered slope can help the outer positioning sleeve quickly enter the inner positioning sleeve, reducing the installation time and improving the operation efficiency. The self-guiding function of the slope reduces the need for manual adjustment and reduces the possibility of human operation errors. The tapered slope can guide the outer positioning sleeve to gradually enter the center position of the inner positioning sleeve, ensuring the positioning accuracy. This design can reduce the gap between the outer positioning sleeve and the inner positioning sleeve, further improving the positioning accuracy of the fixing device. The tapered slope design enables the outer positioning sleeve to smoothly enter the inner positioning sleeve at different installation angles, improving the adaptability. The automatic correction of deviation is realized by the inner positioning sleeve and the outer positioning sleeve, improving the accuracy and convenience of installation.
