Description
Technical Field
The invention belongs to the technical field of excavation and tunneling of rock layers (or soil-rock mixed layers), and particularly relates to a multi-tooth single-cutter tooth roller excavator.
Background
At present, China has become the biggest manufacturing base and application market of the development machine in the world. With the high-speed growth of construction works such as urban road traffic, railways, highways, water conservancy, municipal engineering mines and the like in China, the development of the tunneling machinery in China is also rapid. The heading machine industry in China has become a key supporting and developing industry of the domestic high-end equipment manufacturing industry and the strategic emerging industry.
The tunneling equipment is divided into drilling blasting tunneling equipment and comprehensive mechanical tunneling equipment according to a tunneling process, and the drilling blasting tunneling equipment is widely adopted in China. Drilling and blasting method tunnelling equipment includes: drilling (chiseling) machines, loading machines, transshipping machines, roadway support machines, and roadway restitution machines. The integrated mechanized excavation equipment comprises: cantilever type development machine, continuous miner, combined tunneling and anchoring unit and full-face development machine. Compared with the drilling blasting method, the comprehensive mechanized excavation equipment has the advantages of safety, relative rapidness and high efficiency, and is the development direction of mechanized excavation.
The drilling machine used in the drilling and blasting method is mainly a rock drill, which works by using the principle of impacting and breaking rock. When working, the rock drill needs to complete two basic actions, namely, drilling and rotating. The piston continuously impacts the drill rod tail, and a blast hole with a certain depth can be formed on the rock. Furthermore, to ensure that the drill rod continues to drill efficiently, it is necessary to apply a suitable axial thrust to the rock drill and to discharge the cuttings from the borehole in a timely manner. The types of rock drills are many, and the rock drills can be divided into pneumatic rock drills, hydraulic rock drills, electric rock drills and internal combustion rock drills according to different power.
The comprehensive mechanized excavating equipment mainly comprises a fully mechanized excavating machine. The fully mechanized coal mining tunneling machine is a combined unit capable of breaking and falling rock strata, loading and transshipping, transporting, spraying, dedusting and moving and walking simultaneously. The method has the advantages of high tunneling speed, stable tunneling roadway, reduction of rock caving and gas outburst, reduction of the overexcavation amount of the roadway and the filling amount of support operation, improvement of labor conditions, reduction of labor intensity and the like. Therefore, the fully-mechanized coal mining heading machine plays an increasingly large role in being matched with a fully-mechanized coal mining working face for use.

Detailed Description
The invention is further illustrated by the following figures and examples, which should not be construed as limiting the scope of the invention as claimed.
As shown in fig. 1, a multiple-tooth single-twist-cut-roll excavator is a conventional backhoe excavator 1 to which a multiple-tooth single-twist-cut-roll excavator is attached. The power for moving the multi-tooth single-twist-cut-roller heading machine, the reactive force required by the work (namely the pressure of a machine member on a rock stratum and the twist-cut force of a twist-cut tooth on a rock), the adjustment of the position and the angle of the multi-tooth single-twist-cut-roller heading machine during the work and the like is provided by the backhoe 1. For example, the overall mass of the 800-type multi-tooth single-twist-and-cut-roller tunneling machine is less than 600kg, and the power provided by the conventional 240-type backhoe excavator can far meet the requirements of working conditions.
The multi-tooth single-twist cutting-tooth-roller heading machine comprises: the permanent magnet synchronous driving motor 7 is directly connected with the rolling toothed roller 3 through a bearing, the upper end of the connecting plate 8 is hinged with the movable arm 6 of the backhoe excavator 1, the lower end of the connecting plate is connected with the upper end of the mechanical arm 9, the lower end bearing of the mechanical arm 9 is connected with the rolling toothed roller 3, one end of the hydraulic rod 10 is connected with the movable arm 6 of the backhoe excavator 1, and the other end of the hydraulic rod is connected with the top of the connecting plate 8. In order to prevent the stones splashed out due to the tearing of the rock mass in the operation of the multi-tooth single-twist-cut-tooth-roller tunneling machine from causing damage to field construction personnel and equipment, a dustproof and splash-proof hood 5 is arranged above the rolling tooth roller 3. The two hydraulic adjusting rods 2 are respectively connected with the connecting plate 8 at one end and connected with the two ends of the hood 5 at the other end.
As shown in fig. 2, the tip of the rolling-teeth roller 3 is insert-welded with hard cutter teeth 11 made of a high-strength hard special wear-resistant steel material. Because the permanent magnet synchronous driving motor 7 is directly connected with the rolling tooth roller 3, the effective output of the permanent magnet synchronous driving motor is close to 100 percent before the anti-lock rolling gear does not act, and the conversion loss is very small. The rolling tooth roller 3 is driven by the permanent magnet synchronous driving motor 7 to rotate, and strong twisting force is formed. The optimal incidence angle on the tooth surface of the reaming teeth of the rolling tooth roller 3 is 11-13 degrees, and the stone is torn and reamed and broken at the moment of contact with the hard stone to be excavated.
The driving power supply of the multi-tooth single-twist cutting tooth roller tunneling machine uses an external power supply as much as possible. When the condition is not allowed, the self-power and the hydraulic motor can be used for driving, and when the self-power and the hydraulic motor are used for driving, the power output of the hydraulic motor is only 2 multiplied by 16KW, so that the working efficiency of the multi-tooth single-twist-cut-tooth roller heading machine is reduced greatly. The driving motor power of the 800-type multi-tooth single-twist-cut tooth roller heading machine is 160 KW.
The multi-tooth single-reaming-tooth-roller excavator is suitable for hard stone earthwork engineering under various complex working conditions, and rock strata of calcite, limestone above 3.5 and quartzite below 7.5, granite and below are the most suitable sections of the multi-tooth single-reaming-tooth-roller excavator, so that drilling explosion-free, safe, efficient, energy-saving and environment-friendly rapid construction is realized. When rock excavation and tunneling operations are carried out on rock stratums (quartz rocks, granites and the like and below) with the Mohs hardness of about 7.5, the loosening and crushing capacity of hard stones (quartz rocks, granites and the like) can reach 180% -200% of the efficiency of a back-hoe excavator at the same level. The replacement cycle of the easily damaged part of the tooling equipment is long, the continuously-used tool can be used for 8-9 months every time the easily damaged part is replaced, the planned maintenance and the replacement of the easily damaged part can be realized, the workload for replacing the easily damaged part is small, the time is short, and the replacement of all parts can be completed in 3-4 working hours. The construction noise is low, and the noise of the multi-tooth single-stranded-cutting-roller tunneling machine is less than or equal to 90 dB; the operating noise of the multi-tooth single-strand cutting tooth roller type excavator is less than or equal to 110 dB. The whole set of equipment has low manufacturing cost. The manufacturing, production and debugging of complete equipment and the modification cost of the backhoe comprise the manufacturing cost of the backhoe, and the manufacturing cost is about 100 thousands RMB for the example of the 800-type multi-tooth single-twist-cut-tooth roller type excavator which is modified to the 240-type backhoe in the embodiment, so that the cost is reduced after batch production.
