Technical requirements for pneumatic antenna lifting bracket

Time：2020-08-20 View：

Summary
Nanjing Xuedian science and technology newly developed an improved pneumatic retractable mast, which can support it to rotate in the opposite direction. The mast includes adjacent telescopic segments that can slide relatively between the retractable and stretching positions. The pneumatic retractable mast also provides a pneumatic control system that also makes the mast segment move between the retractable and extended positions. It is a mechanical equipment that makes the mast rotate between the general horizontal and vertical positions.
The pneumatic retractable mast mechanical equipment includes a driving mechanism that can be operated independently of the pneumatic control device, and can reliably keep the mast at any desired angle between horizontal and vertical positions. The pneumatic retractable mast includes a light source installed at its upper end, which can operate with the same DC power supply as the pneumatic control system and the equipment used to rotate the mast.

 

Claims
A pneumatic retractable mast is supported to rotate around a horizontal mast axis in opposite directions. The pneumatic retractable mast includes: multiple adjacent scaling segments that can slide between the retractable position and the protruding position, including the pneumatic control device used to move the pneumatic retractable mast section between the retractable position and the extended position, and the device used to make the pneumatic retractable mast rotate in the opposite direction around the pivot axis between the horizontal and vertical positions. Its improvements include:
The above-mentioned device used to rotate the pneumatic telescopic mast between horizontal and vertical positions, lighting device used for lighting and DC power supply device, the device used for rotating the mast includes driving wheel device, the device used to make the driving wheel device rotate in the opposite direction and the device including the connecting rod device, the connecting rod device connects the driving wheel device and the mast, to make the driving wheel device rotate along one of the above two opposite directions, so as to make the pneumatic retractable mast rotate towards the vertical position, and it is used to make the driving wheel device rotate along the other of the above two opposite directions, so as to make the pneumatic retractable mast rotate towards the above horizontal position, the lighting device used for lighting is installed on one of the adjacent telescopic sections, and the DC power supply device is used to provide power to the pneumatic telescopic mast system, including providing power to the lighting device and the device used for rotating.

Technical introduction:
In terms of working principle and technical characteristics, this mast is equivalent to a multi-section cylinder. When in use, by injecting and discharging air into the cylinder, the rising and falling movements of each cylinder are realized.
Each cylinder is made of high quality aluminum alloy material. The whole manufacturing process has gone through multiple technological technologies such as extrusion molding, cold drawing, honing, machining, anodic oxidation and so on, and has gone through strict inspection procedures, to ensure the quality of the mast.
If you want to know the structure of the mast, please refer to the structure diagram of the mast. If you want to know more, please refer to the relevant technical instructions or contact Nanjing Xuedian company. You will find the advantages of this mast are: simple structure, but precise manufacturing process, so it is convenient to use and stable in performance, and is your ideal product.
The mast specifications are determined according to the number of nodes, maximum node OD, initial height, and maximum height. Different mast specifications have different technical performance.

 

Technical parameters:
Maximum lifting height (unfolded height):1-30M (can be customized according to requirements, see the attached table for common specifications);
