WJD-2FB 1m³ underground explosion-proof electric scraper

1m3 underground explosion-proof electric scraperWJD-2FB underground explosion-proof electric scraper is mainly used in coal roadway, semi coal rock roadway and whole rock roadway of non-metal mines such as coal mine. The top plate, bottom plate and side wall of the road are mainly used to clean, shovel and transport the loose materials after blasting. It can also be used in railway, highway, water conservancy and other tunnel projects, especially suitable for the working face with poor working conditions, narrow, low and muddy working site. This product has obtained the national coal safety certification (it can be used safely in places with explosive gas of gas and coal dust mixture). The power system adopts explosion-proof three-phase asynchronous motor used in coal mine, and the transmission system adopts T90 pump and imported hydraulic mv22 variable motor of Sao Dan Foss company, which is easy to operate and stable. The braking system adopts full hydraulic dual pipeline working braking system, which is safe and reliable in the operation of muddy roadway with harsh environment and high cement content. The main components of the hydraulic system of the car are the components of domestic well-known companies, full hydraulic steering and manual control. All electrical parts meet the requirements of underground operation. WJD-2FB explosion-proof electric scraper has advanced technology, small volume, flexible turning, reliable operation and high operation rate. Performance characteristics:
 (1) The multi-way valve adopts the pilot type, which makes the operation more convenient.
 (2) The bridge adopts the heavy-duty drive axle dedicated to the scraper of a well-known domestic manufacturer. (3) The parking brake adopts imported parking brake cylinder, spring brake, hydraulic release brake, and the brake is safe and reliable.
 (4) The use of single lift and single steering cylinders makes the whole machine more stable and steering more powerful.
 (5) The connection method is central articulation of the slewing bearing and full hydraulic power steering. (6) The bucket adopts a V-shaped structure, and the blade is made of anti-wear alloy material, which is durable.
 (7) All bolts of the whole vehicle adopt high-strength bolts of grade 8.8 or above, and all copper sleeves adopt today's advanced lubrication-free axle sleeves.
Performance characteristics: 1. Front frame, rear frame, boom, bucket: Q345B low-alloy steel of Jinan Iron and Steel is selected as the main material of the frame, and the lower limit of the yield of this material is about 345Mpa, which can withstand all kinds of loads from inside and outside the vehicle. Not only the strength is guaranteed, but also through normalizing, aging, sandblasting, corrosion prevention, a total of seven processes to weld forming. 2. The pin shaft of the whole machine is made of 40Cr alloy steel, which needs to go through 5 processes including rough turning, quenching and tempering, fine turning, quenching, and fine grinding to ensure the stability of the pin shaft during the working period. 3. The copper sleeve of the whole machine is made of high-strength brass and radially embedded with ordered cylindrical graphite filler as friction material. The embedded solid lubrication is easy to form lubricating film, which plays a great role in its friction and wear performance. It has the advantages of high precision, strong bearing capacity and good wear resistance. The anti-wear property is more than 3 times that of the ordinary copper sleeve. 4. The bucket blade and guard plate are made of special alloy wear-resistant materials, which are wear-resistant and shear-resistant, and 1.5-2 times the service life of ordinary wear-resistant steel plate.
