built-in cable pneumatic telescopic mast,pneumatic telescopic mast china
The self-locking mast is a mast with a self-locking device added to the general-purpose mast. Through the self-locking device, the height of the mast can be maintained effectively and for a long time, and it is not necessary to use gas to maintain pressure.
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, and we will design it for you, usually within 48 hours by email way to provide you with a drawing.
According to the model structure of the mast cylinder, the self-locking of the bolts uses the shear force between the full-length foreign keys on the outer wall of the cylinder and the spring pins on the section sleeves to mechanically position each section of the mast. The positioning effect depends on the material and cross-sectional area of the key. Since the material of the mast cylinder is aluminum alloy and the cross-sectional area of the key is small, this latch self-locking device is only suitable for small and medium-sized masts with light loads.
2. About the selection of two types of self-locking pins
Straight-pull self-locking is generally suitable for masts with an initial height of less than 1.6m, and inclined-pull self-locking is suitable for masts with an initial height of more than 1.6m.
I. Overview
The built-in cable pneumatic telescopic mast is a lifting device specially designed for antennas or related equipment under various environmental conditions, which can be used for vehicle mobility or fixed on the ground. The rod body is made of aluminum alloy material and has two lifting modes: electric and manual. The principle of synchronous lifting of each rod body is driven by the synchronous helical rotation transmission of each section of the lead screw, which can be firmly locked at any height within the specified elevation to work; unique Compared with other similar electric lifting rods, its working principle, mechanical transmission form and novel structure design make it better in orientation, faster in lifting speed, smaller in overall size, larger in working load, easier in operation method, and more in installation and fixation. Faster, more stable, reliable and safer work.
At present, this kind of electric lifting pole has formed a series of products such as 5m, 7m, 9m, 12m, 15m, 18m, etc., which can meet the various needs of different users.
2. Structure composition and working principle of built-in cable pneumatic telescopic mast
The pneumatic telescopic mast china is mainly composed of 220V AC motor, reduction gear pair, threaded screw drive pair, aluminum alloy square tubular rod body and motor gear pair housing, lift control switch, electric/manual transfer switch, limit switch, insurance and manual Shaking handle, wire rope and other components. The structure is shown in the figure (taking 7m electric lift pole as an example):
The basic working principle of pneumatic telescopic mast china: in the lift rod body, threaded screws with different diameters are precisely fitted together with the rod body through nuts and seat sleeves and can rotate freely to form a threaded kinematic pair. When working, the reduction gear pair is driven by the AC motor (or hand crank) to drive all the threaded screws to rotate synchronously, and the helical rotational motion of the transmission pair is converted into the linear motion of the rod body through the nut and the seat cover, so as to realize the lifting and lowering of the lifting rod. .
pneumatic telescopic mast china lifting performance
The omnidirectional large-scale mobile lighting vehicle adopts 3 telescopic cylinders as the lifting adjustment method, and the maximum lifting height is 4.5 meters; the light head can be rotated up and down to adjust the beam irradiation angle, and the light coverage radius can reach 35-55 meters.
How pneumatic telescopic mast china works
All-round large-scale mobile lighting vehicles can be directly powered by the generator set, and can also be connected to 220V mains for long-term lighting.
easy to operate pneumatic telescopic mast china.
The opening and closing of each light can be controlled separately within a range of 50 meters by wireless remote control, and the lifting and lowering of the telescopic air rod can be quickly controlled by using an electric or manual air pump.
pneumatic telescopic mast china protection class
The lamp panel, cylinder and generator set are integral structures, and the bottom of the generator set is equipped with universal wheels and rail wheels, which can run on uneven roads and rails. The whole is made of high-quality imported metal materials, with compact structure and stable performance, ensuring that all-round large-scale mobile lighting vehicles can work normally in various harsh environments and climatic conditions. IP54.
pneumatic telescopic mast china customizability
All-round large-scale mobile lighting vehicles According to the individual needs of the city, the standard configuration of this product cannot meet the work needs of users. Generally, manufacturers can adjust the number of lamp heads, power, floodlight or spotlight, retractable cylinder lifting height and generator. Equipment requirements are adjusted.
(2) Features
1. Built-in cable pneumatic telescopic mast lighting performance: The lamp panel is composed of four 500W high-efficiency and energy-saving Philips brand lamps, each lamp head can be adjusted up and down, left and right angles independently according to the needs of the scene, and rotated to achieve 360-degree omnidirectional lighting; The lamp caps are evenly distributed on the lamp panel to illuminate in four directions; the overall illumination takes into account the distance and the distance, the illumination brightness is high, the range is large, and the lamp life is long.
2. Lifting performance of built-in cable pneumatic telescopic mast: Three-section telescopic cylinder is selected as the lifting adjustment method, the maximum height is 4.5 meters, and the lighting coverage radius reaches 35-55 meters.
3. Working time of built-in cable pneumatic telescopic mast: when the generator set is used for power supply, it can work continuously for more than 13 hours once filled with fuel, and it can be used for long-term lighting with 220V mains.
4. Built-in cable pneumatic telescopic mast for easy operability: All-round large-scale mobile lighting vehicle The opening and closing of each light can be controlled separately within a range of 50 meters through wireless remote control, and the lifting and lowering of the telescopic rod can be controlled by air pump or manual air valve.
5. Applicable places for built-in cable pneumatic telescopic mast: The lamp panel, cylinder and generator set are integral structures, and the bottom of the generator set is equipped with universal wheels and iron wheels, which can run on potholes and rails. The overall use of high-quality imported Made of metal material, the structure is compact and the performance is stable, which can ensure normal work in various harsh environments and climatic conditions.
6. The built-in cable pneumatic telescopic mast can be customized: in order to meet the individual needs of customers, the standard configuration of all-round large-scale mobile lighting vehicles cannot meet the user's work needs. , The lifting height of the telescopic gas rod and the equipment of the generator are adjusted according to your requirements.
