At the Beijing Traffic Show 2016, there are not only buses, but also a certain number of special vehicles. Although these vehicles differ in their shapes and functions, they can still be collectively referred to as road transport vehicles. Today, just go with Xiaobian to see the special car on the current traffic technology exhibition.
1. Slurry seal car
Weiyue Special Machinery Slurry Sealer
Weiyue special maintenance machinery exhibited a slurry sealer. The car is based on the surface texture of the old pavement, pouring a durable asphalt mixture, can effectively seal the road, so that the surface of the cracks and water and air insulation, prevent the aging of the road further deepened. Because the aggregates, emulsified asphalt, and additives used are generally slurries, they are called slurry sealers.
2. Asphalt macadam synchronous seal car
Weiyue special machinery asphalt gravel synchronous seal car
In addition to the slurry-sealing vehicles, the Weiyue Special Maintenance Machinery also exhibited a asphalt-hammer synchronous sealer. Different from the slurry in the slurry sealer, asphalt, and additives, the asphalt mortar gravel wheel is mainly based on heated asphalt. And this kind of vehicle is not a simple maintenance of the road surface, but basically belongs to reconstruction.
3. Road facility cleaning vehicle
Beijing First Engineering Co., Ltd. clear-cut multi-functional road facilities
In this exhibition, Beijing First Highway Engineering Co., Ltd. exhibited two products, one of which was a multi-purpose road facility cleaning vehicle. There are professional cleaning equipment in front of the car, spray equipment in the middle, and a water tank in the rear. In this way, the vehicle can clean the guardrails, partitions, and other facilities on both sides of the road during driving, which is very convenient.
4. Washing vehicle
Xugong Sweeper
The XCMG Group valued this exhibition very much and exhibited a variety of equipment that mainly consisted of road construction, maintenance, and maintenance. Among them, there is a washing vehicle. The vehicle uses Dongfeng Tianjin chassis, which integrates sweeping and high-pressure cleaning. It has high work efficiency and good maneuverability. At the same time, various operations can be performed centrally in the cab, effectively reducing the driver's workload.
5. Pavement Maintenance Vehicle
Xugong Road Maintenance Vehicle
XCMG also exhibited a road maintenance vehicle. The car has various functions such as feeding, heating, cutting, asphalt spraying, discharging, compaction, and waste storage. Another feature of the car is that it has an independent Perkins engine and generator that can be directly output when the chassis is not working. This makes the vehicle more economical.
6. Tunnel Measurement Vehicle
Wu Da Premier Tunnel Measurement Vehicle
Wu Da Science and Technology exhibited a tunnel measurement vehicle. The center of the car is in accordance with the lighting and detection agencies, can directly detect the tunnel, and the calculation and analysis system at the rear will analyze the situation based on the detection to determine whether the tunnel is safe. Such a vehicle was the first time Xiao Bian saw it at the show.
This lens is made of curve shape, not sphere. The aspherical lens has surface, shown in parabolic surface and polynomial expression. Ellipsoid, hyperboloid, fourth curved surface are examples,Aspherical lenses are designed to reduce spherical aberration
aspheres, are available molded, CNC-polished, or MRF-polished, either with or without anti-reflection (AR) coatings. Aspheres are often employed to collimate light exiting a fiber or laser diode. The surface of an asphere is designed to eliminate spherical aberration.
An Aspheric Lens or asphere is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens.
Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations, We could provide Plano Convex Aspheric Lens, plano concave aspheric lens, double convex(biconvex)aspheric lens
