Product features:
·The chisel head is made of high hardness alloy, with large impact force and long service life.
·Good shock absorption structure ensures comfortable operation of the operator.
·The structure design is scientific and reasonable, and the replacement of chisel head and cutter sleeve is simple.
The hand push roughing machine is mainly used for roughing the surface of expressways, airport runways, airports, parking lots, floors, etc. The reason is the same. Both concrete members and cement structural members can be roughened by roughing machine. The 11 head roughening machine can be used for roughening large area cement formwork.
During construction, the concrete pavement layer shall reach the design concrete strength, and the surface shall be flat, clean, and free of impurities, oil stains, dust, etc. The concrete surface of the bridge deck pavement shall be roughened with a roughing machine to remove the laitance and sundries on the surface, and then cleaned with a rotary wire brush cleaner. Then, the floatation, sedimentation and fine particles shall be removed with a blower or vacuum cleaner, and the concrete surface shall be washed with a high-pressure water gun. After drying, the construction can be started. The main reason for roughening is to chisel away the laitance on the concrete surface, so that the concrete at the new old junction is dense and firmly bonded.
Concrete roughening machine is mainly used for danger removal and reinforcement, for example, it is widely used in many engineering fields such as expressway, high-speed railway, bridge, tunnel, airport construction, water conservancy and hydropower, flood control embankment, nuclear power engineering, large container yard, urban construction and reinforcement, etc. Generally, in cast-in-place structures, after the cast-in-place slab is poured, roughening is required to carry out the pouring of the next layer of column wall. Let the concrete bond firmly.
The chiseling method of the traditional mechanical chisel is to use a sharp striking tool to carry out piston striking on the concrete surface to make the new and old concrete bond firmly. However, the traditional chiseling method has various disadvantages, such as low efficiency, mechanical vibration force causes sound wave transmission, which damages the chiseling main body and thus affects the service life of the chiseling main body. At present, for small area chiseling (local chiseling, facade chiseling, side chiseling, top chiseling), hand-held small chiseling machine can be used, which has good effect and will not damage the original structure. Because many of the current chiseling machinery products will not only damage the protective layer of reinforced concrete, but also cause damage or even catastrophic damage to the original structures, many large-scale mechanical chiseling machines have been prohibited from being used in many projects, especially in the concrete chiseling of bridges and tunnels.
The accessories of the roughing machine are chiseled with high-pressure water, which is fast, has good chiseling effect, does not produce vibration on the structure, has no dust on the surface, and belongs to non-destructive chiseling, does not produce vibration on the concrete aggregate. It is an environmentally friendly chiseling process at present, and is worth promoting in China. High pressure water roughening machine parts can adapt to a variety of projects to ensure the quality and efficiency of project construction.
The roughening machine is equipped with effective welding gaps, which increases the welding area, high welding strength and long service life. The utility model has the advantages of novel structure, scientific and reasonable design, and convenient use, which effectively improves the overall quality of milling teeth. Milling machine and chisel head blade series products are suitable for milling and planing works of various types of pavement and subgrade.
Maintenance of roughening machine accessories
1. The accessories of the roughing machine include various bearing parts, which shall be greased once a week. The chains of the roughing machine accessories can also be greased regularly to maintain good lubrication. At the same time, attention shall be paid to avoiding sand and other sundries on the chain to prevent premature damage of the chain.
2. At the end of almost one month or each phase of the project, a comprehensive inspection and maintenance shall be carried out for the chiseler accessories of the whole machine.
3. The tightness of the parts of the roughing machine, including the tightness of the triangle belt and chain, should be paid attention to from time to time. If it is too loose, it should be adjusted in time. Each fastening bolt should also be checked from time to time to prevent loosening. The flatness and levelness of the ground are increased by more than 3 times, and the compactness and strength are increased by more than 20%. At the same time, it may also increase work efficiency by more than half and save about 35% of labor.
Chiseling machine accessories can easily pave high-strength concrete, low slump concrete and fiber mud concrete. Its laser system is equipped with a variety of automatic control elements. The roughing machine accessories monitor the elevation of the leveling head in real time at the frequency of 10 times per second to ensure that the flatness and levelness of the paved ground are effectively controlled.
