Description
Technical Field
The invention relates to a vibration mill, in particular to a special-shaped vibration mill with bumps.
Background
The road roller belongs to the field of road equipment in engineering machinery, is widely used for the filling compaction operation of large engineering projects such as high-grade highways, railways, airport runways, dams, stadiums and the like, and can roll sandy, semi-viscous and viscous soil, roadbed stabilized soil and asphalt concrete pavement layers.
The machine is suitable for various compaction operations under the action of the gravity of the machine, so that the compacted layer is permanently deformed and compacted. And also can be divided into a steel wheel type and a tire type.
The grinding wheel is constructed with light roller, sheep foot roller, etc. The most common applications of smooth grinding are mainly used for compacting pavement surface layers. Mechanical or hydraulic transmission is adopted, the protruding part can be compacted by concentrated force, the compaction flatness is high, and the method is suitable for asphalt pavement compaction operation.
Single-shaft single wheels, double-shaft double wheels, double-shaft three wheels, three-shaft three wheels and the like are arranged according to wheel shafts. The internal combustion engine is used as power, and mechanical transmission or hydraulic transmission is adopted. The front wheels generally steer, have good maneuverability and are driven by the rear wheels. In order to improve the steering and rolling performance, an articulated steering structure and an all-wheel drive are preferably adopted. The front wheel frame is hinged with the frame to reduce the swinging of the body when the road surface is uneven. The rear wheel and the frame are rigidly connected. The steering is controlled by hydraulic control and a hydraulic cylinder. The front and the rear rollers are provided with scrapers to remove the adhesive on the rollers. And the spraying system is also arranged and used for spraying water to the grinding wheel to prevent the asphalt mixture from adhering when the asphalt pavement is compacted. In order to increase the acting force, iron, sand, water and the like can be additionally arranged in the grinding wheel to increase the weight.
The main technical parameters of the steel wheel type road roller are the weight and the line pressure. In the 80 s, the weight ranges of various steel wheel type road rollers are about 2-13 tons of two-wheel road rollers, 1-15 tons of three-wheel road rollers, the weight can be increased by 1-3 tons as required, 13-14 tons of three-shaft three-wheel road rollers, and the increased weight is 18-19 tons.
The grinding wheel adopts pneumatic tire, generally adorns 3 ~ 5 of front wheel, 4 ~ 6 of rear wheel. If the inflation pressure is changed, the grounding pressure can be changed, and the pressure adjusting range is 0.11-1.05 MPa. The tyre road roller adopts a hydraulic, hydraulic or mechanical transmission system, is driven by a single shaft or a full shaft, and is supported by a wide-base tyre articulated frame structure at three points. The compacting process has a kneading effect, so that particles in a compacting layer are embedded without being damaged, and the compacting layer is uniform and compact. The machine has good maneuverability and high running speed (up to 25 km/h), and is used for compacting engineering cushions of roads, airports and the like.
The towed vibratory roller can effectively compact various soils and rock fillings, and is suitable for engineering construction of modern highways, airports, embankment fillings, harbors, dams, railways, mines and the like
A plurality of bumps are arranged on the roller. Since the shape of the bumps is similar to that of sheep feet, it is called sheep foot roller, also called sheep foot roller. The shape of the convex block is sheep foot shape, cylindrical shape, square column shape, etc. The roller shaft is supported on the traction frame bearing, so that the application range is expanded. The roller can be filled with water, sand or iron sand to increase the rolling weight. Comb-shaped scrapers are arranged below the machine frame in front of and behind the roller to remove mud blocks stuck and embedded between the convex blocks.
The towed sheep foot roller is towed by a tractor. Self-propelled sheep foot grinds also known as tamping road roller. The sheep foot roller has high unit pressure, uniform filler, tamping effect and high compactness, and is especially suitable for compacting viscous soil and rubble layers for hard clay. Especially for hard clay, the bumps have the functions of stirring, kneading and tamping, so that the filler is uniform, and the upper and lower layers are well bonded to avoid layering. It is widely used for compacting roadbeds, cushion layers, dams and other projects.
The self-propelled sheep foot roller can be further provided with an excitation device in the roller to manufacture a vibration tamping road roller, the vibration force is utilized to increase the compaction effect, and the roller can be filled with water, sand or iron sand to increase the rolling weight. The application range is enlarged.
And a vibration roller (vibro roller) is a machine for compacting soil, gravel or rockfill material using vibration and amount of vibration. The split-dragging type and the self-walking type. The maximum weight of the tractor is 14 tons, and the self-propelled maximum weight of the tractor is 16 tons. It is composed of machine frame, diesel engine, driving mechanism and eccentric vibration mechanism. The eccentric block is driven by power to run at high speed to generate vibration force, and the pressed material surface is compacted under the combined action of static gravity of a rolling body through the rolling wheel. It is composed of machine frame, diesel engine, driving mechanism and eccentric vibration mechanism. The eccentric block is driven by power to run at high speed to generate vibration force, and the pressed material surface is compacted under the combined action of static gravity of a rolling body through the rolling wheel. The maximum compaction force can reach 50 tons, the vibration frequency is 1800 times/min, and as the grinding wheel of the vibration mill is a curved surface and the contact area with the pressed surface is smaller, the unit compaction force is strong, the influence range is large, the compaction depth is thicker, the effect is good, the productivity is high, and the grinding wheel is most suitable for compacting gravel, rockfill and the like of an earth-rock dam. The self-propelled vibrating grinding wheel comprises a flat wheel, a sheep foot wheel and a bump wheel.
The traditional road rollers adopt the characteristics of high frequency and low amplitude to roll in construction, and the rolled body can reach the required compaction degree only by more construction rolling times, so that the efficiency is lower, the power consumption is more, and the problem is overcome by a novel vibration roller.
Disclosure of Invention
The invention aims to solve the technical problem of providing a special-shaped vibration roller with a lug, wherein a non-circular rolling wheel which is different from a traditional vibration roller is adopted, the non-circular rolling wheel can not only vibrate and roll but also can pass through the impact energy of the non-circular rolling wheel in the rolling process, and the non-circular rolling wheel are combined to provide a novel high-frequency and high-amplitude rolling mode, so that the rolling effect is greatly improved, the construction efficiency is improved, and the power consumption is reduced.

The rolling driving speed is 3-5 km/h, the efficiency is improved by 3-4 times, and the compaction effect can be achieved only by a small number of rolling times. The settlement rate after rolling is about 0.4%, even can reach 0.1% -0.15% in the filling area, can better avoid the cracks caused by differential deformation, and can well reduce the settlement deformation after construction in the rolling of the earth-rock dam; in the construction of the roller compacted concrete, the rugged layer surface can be formed on the roller compacted surface, which is beneficial to the combination of the roller compacted concrete layers.
