1. Foreword With the acceleration of China's infrastructure construction, the state has increased its investment in infrastructure, including increasing investment in infrastructure construction in the central and western regions, such as “West-East Gas Transmissionâ€, “West-East Power Transmission†and “South-to-North Water Transferâ€. The launch of large-scale projects such as the Qinghai-Tibet Railway and the construction of domestic expressways; at the same time, with the advancement of urban construction in China, the increase in the number of towns, the expansion of urban scale and the enhancement of functions, special-purpose vehicles for various commercial transportation are facing greater demands. Among them, special vehicles such as dump trucks, concrete mixer trucks and bulk material transport vehicles required for urban construction will inevitably increase.
Trailer has become one of the fastest-growing models in recent years. Due to its series of advantages such as high loading quality, small loading and unloading strength, high transportation efficiency, low cost, and economical and environmental protection, its market demand has increased year by year. Bulk material transport The material loaded in the semi-trailer is blown off by compressed air with a certain pressure. The gas sources that generate compressed air mainly include three methods: vehicle air compressor, external air source, and exhaust gas from automobile engine. At present, bulk material transport semi-trailers are generally blown and discharged using compressed air generated by a vehicle air compressor. The power source of the vehicle air compressor can be roughly divided into the following three ways: the power take-off of the traction chassis is driven by the drive shaft, the diesel engine drive and the motor drive.
The power take-off of the traction chassis is driven by a drive shaft driven device. The power take-off of the traction chassis is driven by the transmission shaft. The driving device is mainly composed of a power take-off, a transmission shaft, a bearing housing, a pulley, an ordinary C-shaped V-belt, etc. (see,).
Firstly, one end of the power take-off device is connected with the transmission on the traction chassis, and the other end is connected to the transmission shaft. The transmission shaft is connected with the pulley, and the C-type V belt is used to drive the air compressor to generate compressed air.
The power transmission route of the driving device is: traction chassis transmission, power take-off, transmission shaft, bearing housing pulley, C-type V-belt, and air compressor.
The physical picture of the diesel engine-air compressor unit installed on the frame of the semi-trailer frame is that the installation space is reasonable and the length of the trailer can reach the legal maximum limit. The disadvantage is that the tractor transmission can not realize the hanging transportation of the semi-trailer; the parts of the transmission shaft connecting device are complicated to process, the installation is cumbersome, the labor time and the raw material processing cost are high.
3. Diesel engine driving mode This kind of driving device is composed of diesel engine and C-type V belt (see,). The driving route of the driving device is diesel engine-C-type V-belt-air compressor, which is called diesel-air compressor unit.
The advantage of the device is that the installation is simple and convenient, and there is no need to increase the transmission shaft and the transmission shaft fixing device; the transmission route is simple, the power loss during the transmission process is small, and there is no requirement for the discharge site. The disadvantage is that the self-quality is large and the space is large.
The installation position of the diesel engine-air compressor unit is generally in front of the traction chassis frame or the tank body on the semi-trailer frame, which facilitates the transportation of the semi-trailer.
4. Motor drive mode This type of drive consists of a motor, a control unit, and a C-type V-belt. When the driving device is running, the power route is: motor-C-type V-belt-air compressor (see).
The advantage of the device is that the driving device is simple and convenient to install, no need to increase the transmission shaft and the fixing device, the transmission route is simple, the power loss in the transmission process is less, and the running cost is saved. The disadvantage is that electrical cabinets need to be installed and power is required at the unloading site.
This paper briefly introduces several driving devices for air compressors for bulk material semi-trailers, and analyzes their advantages and disadvantages to help users better understand the applicability of air compressors for bulk material semi-trailers, and according to different The transportation environment is chosen.
