Research On Tunneling And Grouting Equipment

In recent years,the subway has become a very important way of people travel.In subway tunnel construction,blasting is a basic work.But the drilling and blasting method will damage the stability and permeability of the rock and damage the buildings on the ground.In order to avoid the damage caused by the blasting on the ground and other damage,it is proposed that the part of the tunnel blasting and the tunnel wall through a separate separation of the separation method to avoid or improve the impact of blasting.However,the formation of the tunnel section isolation has been only stayed in the idea so far because of no special equipment.Tunnel section grooving machinery research for this situation is put forward.The research content of this project is to develop a new tunnel slotting machine,so that the device can have the function of excavation trench.Because of no mature experience and products to learn from in the design study it can only according to its function and construction requirements,the machine required work systems and components for analysis,research and design.Unlike other engineering machines,the new slotting machine operates with the grooved bit during the course of the tunnel wall movement,which is approximately perpendicular to the ground plane of the tunnel.According to the basic functions of the new tunnel trenching machine,the design of the whole structure of the equipment is completed,and the arrangement of the system and the system of the whole machine are determined.The working system can only be concentrated in the vertical panel parallel to the section,and the working position of the grooving tool is also located in the vertical section,under which the composition and design of the working mechanism are caused to be relatively large difficult.Taking into account the work is the pre-blasting preparation time,the tunnel construction site without explosive dangerous goods,the use of construction power is proposed as a power source when the equipment work,and the horizontal motor is selected as the power source of the transmission system.In order to transmit power to the vertical tunnel section of the drill,the power transmission system can not use single-stage mechanism.According to the position of the motor and the arrangement of the drilling tools,the combination of bevel gear and chain drive is proposed,which can meet the conditions of power transmission of work agencies,and can achieve the dynamic touch requirements.The device works by the end and the side of the drill bit and the continuous role of the rock to complete the excavation process.The existing rock drill bit only work by the end of the drill,for the equipment drill bit is an important key point of the whole equipment.Through a lot of analysis and research,with the reference to the structure of various types of metal processing bits,combined with the design work requirements of the design,a unique new drill bit with drilling and grooving function is proposed,and designed the drill bit structure and supporting the drill pipe and other institutions in detail.The tunnel slotting machine is designed to meet the pressure feed requirements of the mobile guide mechanism to pressurize the system,which is another innovation of the new slot machine in the working organization.The above-mentioned mechanism apparatus is integrated on a vertical plane with a side length of 1 m,and the work plane is operated on a pre-laid track of a vertical section.Through the above-mentioned various components and systems of the joint role,the blasting pre-slot with the surface of the bread on the span of about 12 meters,1.5 meters in depth,width of 100 mm blasting pre-groove is completed.In the new research and development of slotting machine,the whole program design and the detailed structure of the work of the study of important parts of the relevant movement analysis and force analysis is completed.And the important parts of the check strength are completed;besides the selection of motor design is completed.To ensure that the parts can work stably,the work of the important force analysis of the key components is completed with finite element software ANSYS.
