I. Introduction

Pneumatic locking device with self-lifting rod products have been widely used in aerospace, telecommunications, telecommunications, military, television, on-site lighting, fire and lightning protection equipment, such as mobile. Such pneumatic locking device with self-lifter Simple operation, landing rapidly. Site selection and flexible, good reliability, suitable for car or base communications. Has a light texture, strong bearing capacity, bending, torsional resistance, good linearity characteristics. Since the orientation of the pipe wall is mounted, has a good orientation function. Self-locking lift rod design reasonable, simple, affordable, manual lifting, easy to operate, saving time and effort. With load, low noise, fast movements, shock resistance is small, strong self-loading buffer performance, smooth and so on. Our products are made of high strength aluminum alloy, light weight, can meet the different areas, the demand for different occasions height and load, such as the military, police, civil and other fields, in a variety of natural disasters, emergencies and rescue scene at night, plays an important role in the rescue. In addition, the company's products are also widely used in golf, a large soccer field at night lighting.

Second, the technical indicators

A collection Height: customized according to customer requirements

2 Total elevated height: customized according to customer requirements

3 Installation: customized according to customer requirements

4 Material: high-strength aluminum-magnesium alloy extrusions, strong corrosion resistance; cylinder walls using high-pressure treatment process seal wear and porcelain join. ;

5 packing properties: a high level of sealing performance, the stationary state 24 hours lifting mast fell less than 10mm. Gassing swinging piston stroke using the structure that a piston with high strength heavy graphite-containing PTFE; transmission are all closed, the rubber sealing ring (the ring body and the rod between the rod Japan imported seals NOK), waterproof sand performance, strong corrosion resistance;

6 Surface treatment: hard anodized aluminum-magnesium alloy increases the intensity profiles;

7 wind resistance: rod pneumatic lifting device with a self-locking lever using circular cross-section, in the same installation space, circular cross-section can provide higher strength, stiffness, torsional and bending ability ability; wind 8 level; has anti-rotation function, working pressure: <0.30 Mpa ;..

Pneumatic 8 with self-locking device has a built-lift rod structure lines; my company first realized the device control and power cables inside the lift rod fixed at the earliest to achieve the lift rod internal traces on the appearance and performance on further.

9 car lift mast is through the roof fixed, or installed in vehicles surrounding and supporting frames by dragging the disc and joint fixation. Customer equipment selection, car lift mast should be determined according to the different type of the original height of the top of the mounting surface height. Resulting self-locking lever mounted on the top of the lift, its original height of the shortest ensure that the body has the greatest height by sex and try to reduce the drag of the device.

Third, the performance advantages

Pneumatic lift rod with self-locking devices are made of high quality aluminum alloy material, the entire manufacturing process through extrusion, drawing, honing, machining, anodizing and other multi-channel technology, and undergo a rigorous inspection process, to ensure the quality of the cylinder. To understand the structure of multi-section lift cylinder case, a detailed multi-section lift cylinder structure. Aerodynamic advantage with self-locking device lifters are: simple structure, the manufacturing process of precision, so easy to use, stable performance. Specifications pneumatic lift with self-locking device in accordance with the different number of rods Festival, the largest festival diameter, initial height, maximum height and determined. Pneumatic self-locking device with different specifications of the lift rod different technical properties.

Fourth, the use of technical notes

Self-locking latch is based on the structural characteristics of the mast cylinder model, the shear force of the entire length of the cylinder wall section of the foreign key and put the spring pin between the mast sections for mechanical positioning. Its effect depends on the location and the cross-sectional area of the key material. Because the material is aluminum mast cylinder, cross-sectional area bonds is small, so that the latch lock device is only applicable to small and medium load lighter mast.

Straight pull self-locking generally applicable to the initial height of 1.6m below the mast, cable-stayed self-locking applies to the initial height of 1.6m above the mast.

Brake lock braking effect is realized by holding the friction between the brake lever and lift, the equivalent of wheels and brakes. When using the self-locking brake mast requires spin hug gates. Braking force required size, depending on the size of the decision of loads, the more tight spin braking force greater. The actual operation, the use of a torque wrench, you can clear whether the braking force to meet the load requirements. Wrench or torque wrench is optional, self-locking brake braking force is calculated by using the formula screw tightening torque.

For tightening torque value, Nm

Screw receiving optimum clamping force F, N;

d thread diameter, mm; [1] P is the thread pitch, mm

Integrated brake and separate brake brake can achieve the same effect, the difference is that the design can meet the initial height of the mast, the greatest increase, requiring load. Under the same conditions, the separation of the initial brake-in holding the lower mast height can be made higher or liters.

Five, pre-service: We accept OEM product customization and production needs. Even with a standard product, due to different customers different requirements, some indicators are not the same concern. As long as you put forward arguments on the lift rod requirements, from total height, shut height, wind resistance, vertical load, partial load, lifting time,, yaw to the power requirements of form, weight, installation methods, we are responsible to you to customize a shall belong to your private lift rod.

Six, after-sales service: technical staff can arrange installation guide. Warranty: One year replacement, a three-year warranty and lifetime maintenance (within 48 hours to reach the scene).
