Audited Supplier Road milling machine is one of the main types of asphalt pavement maintenance and construction machinery, and one of the main equipment for asphalt concrete pavement maintenance and construction. It is mainly used for the excavation and renovation of asphalt concrete surface layers on highways, urban roads, airports, freight yards, etc. It can also be used to remove defects such as road bumps, oil waves, mesh patterns, and ruts. It can also be used to excavate road pits and grooves, as well as for the roughening of cement pavement and milling of surface layer misalignment.
1. Waterproof treatment and chiseling on the surface of the bridge deck, as well as the flatness and waterproofing treatment of the high-speed railway box girder surface.
2. Milling and removal of bumps, ruts, cracks, and potholes on asphalt pavement. Remove ice and snow from the bridge deck and road surface.
3. Before the new laying of asphalt concrete, the existing old road surface should be lightly roughened, or a large milling machine should be used to complete the milling and roughening operations in the edge and steel reinforcement dense areas.
4. Remove ground coatings, paint, and various traffic markings; When the ground is damaged or dirty and needs to be renovated, remove the old floor surface, etc.
5. Remove airport road markings, aircraft runway tire brake marks, etc., and regain a rough surface with high friction coefficient.
6. Milling and leveling of over elevation areas on cement asphalt pavement, highway bridge deck, bridge misalignment, and epoxy resin wear-resistant ground.
7. Construction of road micro surface, milling and removal of existing old pavement surface layer to prepare for slurry sealing layer
The main structure and working principle of a general milling machine are composed of an engine, frame, milling rotor, milling depth adjustment device, hydraulic components, aggregate conveying device, steering system, and braking system. The milling rotor is the main working component of the milling machine, which is composed of the milling rotor shaft, cutter seat, and cutter head. It directly contacts the road surface and works through its high-speed rotating milling cutter to achieve the purpose of milling.
The milling machine is equipped with an automatic leveling device, which uses the milling rotor side cover as the milling reference surface to control two positioning hydraulic cylinders to maintain a constant milling depth; Its hydraulic system is used to drive the rotation of milling rotors, the walking of the entire machine, and the operation of auxiliary devices. It is generally a closed hydraulic system with multiple independent pumps, which does not interfere with each other and has high reliability during operation; Some milling machines are equipped with tilt adjusters as needed to control the inclination of the rotor; Generally, large milling machines have an aggregate conveying device composed of a conveyor belt and an aggregate feeder. It can concentrate the milled loose materials and transport them to a randomly moving transport vehicle. The height of the conveying arm can be adjusted and can swing left and right to adjust the unloading position. The specifications and models of milling machines vary, and their structures and arrangements also differ slightly, but their basic working principles are the same or similar. The power transmission route of milling machine: engine → hydraulic pump → hydraulic motor, hydraulic cylinder → working device.
