Self-locking mast is a mast with self-locking device added to general-purpose mast. Through the self-locking device, the mast height can be effectively maintained for a long time without using gas to maintain pressure.
At present, our company has designed two types of self-locking masts: straight-pull bolt self-locking masts (AX) and stud self-locking masts (AXT). The specification includes the number of nodes, the initial height, and the maximum height.
Bolt-type self-locking mast is only suitable for small-sized and light-loaded masts.
Bolt-type self-locking can be used not only for upright masts, but also for supporting frame-type masts.
You can choose the specifications you need from our existing products.
If there is no mast that meets your requirements in the existing specification sheet, you need to contact us and tell us the initial height, maximum height and load weight of the mast you want. We will design it for you, generally, a drawing is provided to you by email within 48 hours.
Bolt self-locking is to mechanically locate each section of the mast according to the model structure characteristics of the mast cylinder and the shear force between the full-length outer key of the outer wall of the cylinder and the spring pin on the joint sleeve. Its positioning effect depends on the material and cross-sectional area of the key. Because the material of the mast cylinder is aluminum alloy and the cross-sectional area of the key is very small, this bolt self-locking device is only suitable for small and medium-sized masts with light load.

 

2. Selection of two kinds of Bolt self-locking
The straight-pull self-lock is generally applicable to the mast with an initial height of less than 1.6m, while the vertical self-lock is applicable to the mast with an initial height of more than 1.6m.

Pneumatic lifting rod is also called pneumatic lifting rod, which is divided into two categories: manual and automatic. According to industry division, there are communication lifting rod, antenna lifting rod, military lifting rod, lighting lifting rod and so on.
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 of pneumatic rod 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.
I. Product characteristics of pneumatic lifting rod
Pneumatic lifting rod has the advantages of high load, low noise, fast lifting, low shock resistance, strong self-falling buffer performance, stability, etc.
II. Application fields of pneumatic lifting rod
Mobile Command Post, various natural disasters and Emergency Events play an important role in on-site night rescue and rescue. Golf, night lighting for large football fields.
III. Pneumatic lifting rod process
Made of high-strength aluminum alloy with light weight, it meets the requirements for height and load in different fields and occasions.
IV. Application prospect of pneumatic lifting rod
Pneumatic lifting rod is widely used in military, police, civil, fire, communication and other industries
V. Technical description of pneumatic lifting rod
Bolt self-locking is to mechanically locate each section of the mast according to the model structure characteristics of the mast cylinder and the shear force between the full-length outer key of the outer wall of the cylinder and the spring pin on the joint sleeve. Its positioning effect depends on the material and cross-sectional area of the key. Because the material of the mast cylinder is aluminum alloy and the cross-sectional area of the key is very small, this bolt self-locking device is only suitable for small and medium-sized masts with light load.
The straight-pull self-lock is generally applicable to the mast with an initial height of less than 1.6m, while the vertical self-lock is applicable to the mast with an initial height of more than 1.6m.
The self-locking of the brake is to realize the braking effect through the friction between the brake and the lifting rod, which is equivalent to the wheel and the brake device.
When the pneumatic lifting rod uses the lock lock self-locking mast, it needs to tighten the lock. The required braking force depends on the size of the load. The tighter the rotation, the greater the braking force. In actual operation, use torque wrench to know whether the braking force meets the load requirements. Wrench or torque wrench are optional accessories, and the calculation method of brake self-locking braking force is to adopt the formula of screw tightening torque.
To tighten the torque value, Nm
F bolt bears the best clamping force, N;
d thread diameter, mm;[1]P is thread pitch, mm
The integrated brake and the separate brake can achieve the same braking effect, and the difference lies in whether the design can meet the requirements of the initial height, maximum rise and load of the mast. Under the same conditions, the initial height of the split lock mast can be made lower or higher.
With the increasing demand for pneumatic lifting rod products, more and more attention has been paid to the application research of pneumatic lifting rod products. At present, the products have been expanded to various fields. It also plays a very important role in the military and aviation fields.
