Application and technical index of lifting rod of lightning arrester equipment

Time：2020-09-01 View：

Application of lightning arrester lifting rod in Nanjing Xuedian. Lightning arrester lifting rod adopts movable triangular bracket lifting rod, which has the advantages of convenient operation, light weight, strong mobility and so on, and is equipped with military canvas bag, which can be completely lifted and transported by a single person.
Tripod mast is equipped with three metal supporting legs on the basis of general-purpose mast, self-locking mast or built-in cable mast. When in use, the supporting legs are expanded and placed on the ground. After use, it can be stored in canvas bags for easy carrying.
At present, the models of tripod mast designed by our company can be divided into two types according to the structure of supporting legs: unadjustable supporting legs (A + code B) and adjustable supporting legs (A + code K). The specification representation method of tripod mast is basically the same as that of general-purpose mast, including the number of sections, initial height and maximum height.
The tripod mast is a portable lifting device. Generally, the load is not large and the height is less than 10 meters. For this reason, the tripod masts designed and manufactured by our company are mostly equipped with Bolt self-locking devices, so as to maintain the height for a long time. When in use, the air pump is generally not used, but can be pulled out by hand or using a pump.
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.

Lifting lightning arrester, pneumatic lifting mast tower, automatic lifting tower mast, mobile communication cabin base station, mobile command vehicle with heavy load, low noise, fast lifting, low shock resistance, strong self-falling buffer performance, stability and other advantages. The company's lifting lightning arrester, pneumatic lifting mast tower, automatic lifting tower mast, mobile communication cabin base station, Mobile Command vehicle products are made of high-strength aluminum alloy, light weight, can meet different categories, the demand for height and load in different places plays an important role in the night rescue and rescue of various natural disasters and emergencies.

 

II. Technical indicators
1 Collection height: customized according to customer request
2 Total height increase: customized according to customer request
3 Device mode: customized according to customer request
4 Material: high-strength aluminum-magnesium alloy profile is adopted, which is highly corrosion resistant; The inner wall of the cylinder is sealed and combined by high-pressure wear-resistant porcelain treatment process.
5 Pressure maintaining performance: high degree of sealing performance, 24-hour lifting mast sliding less than 10mm in static state. Adopt the punching structure of piston swing stroke, and the piston with heavy structure adopts high-strength graphite-containing polytetrafluoroethylene data; All transmission systems are blocked, there is a rubber RS between the rod body and the rod body to stop sealing (this RS is the seal NOK imported from Japan), which has good waterproof and sand-proof performance and strong anti-corrosion ability;
6 External surface disposal: hard oxidation increases the strength of aluminum-magnesium alloy profiles;
7 wind resistance ability: our Rod body adopts circular cross section. In the same device space, circular cross section can provide higher strength, rigidity, torsion resistance and bending resistance; Wind resistance level 8; it has the function of anti-rotation., working pressure:<0.30 Mpa;.
8 Structure with built-in wire: Our company firstly fixed the pilot wire and power line of the equipment inside the lifting rod, and completed the internal wiring of the lifting rod at the earliest in China, further improving in beauty and application performance.
9 The vehicle-mounted lifting mast is fixed on the car roof, or installed around the car, and fixed through the combination of tug and support frame. When selecting the client equipment, the original height of the vehicle-mounted lifting mast should be determined according to the height of the device surface to the top of different types. As a result, when the product is installed on the top, its original height is the shortest, ensuring the maximum height of the car body and minimizing the wind resistance of the equipment.

III. Use technology to clarify
Bolt self-locking is based on the model construction characteristics of lifting lightning arrester, pneumatic lifting mast tower, automatic lifting tower mast, mobile communication cabin base station and mobile command vehicle, apply the shear force between the full-length outer key of the outer wall of the cylinder body and the spring pin on the joint sleeve to stop the mechanical positioning of each section of the mast. The positioning effect is determined by the key data and cross-sectional area. Because the data of the mast cylinder is aluminum alloy and the cross-sectional area of the key is very small, this bolt self-locking installation is only suitable for small and medium-sized masts with light load.
Direct-pull self-locking is generally applicable to masts with an initial height of less than 1.6m, and vertical self-locking is applicable to masts with an initial height of more than 1.6m.
The self-locking of the brake is to complete the braking effect through the friction between the brake and the lifting rod, which is equivalent to the installation of wheels and brakes. When you use the lock lock to lock the mast, you need to tighten the lock lock. The required braking force depends on the size of the load. The tighter the rotation, the greater the braking force. In practice, the torque wrench can be used to identify whether the braking force can meet the load request. Wrenches or torque wrenches 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 accepts the Best clamping force, N;
d thread diameter, mm;[1]P is thread pitch, mm
The integrated brake and the detached brake can achieve the same braking effect, and the difference lies in whether the design can meet the requirements for the initial height, maximum rise and load of the mast. Under the same conditions, the initial height of the detached lock mast can be made lower or higher.

 

IV. Pre-sales service:

We are responsible for product customization and OEM consumption. Even if the same standard of lifting lightning arrester, pneumatic lifting mast tower, automatic lifting tower mast, mobile communication cabin base station, mobile command vehicle, different customers due to different application requests, some indicators of concern are also different. You only need to ask for the parameters of the lifting rod, from the total height, closing height, wind resistance, vertical bearing, eccentric load, lifting time, deflection request to power mode, weight, device mode, etc, we will customize a special lifting rod for you.

 

V. After-sales service:

Technical personnel can be arranged to guide the device. Warranty: one-year replacement, three-year warranty and life-long maintenance (arrive at the site within 48 hours).
