Description

Rocker arm type tunneling machine
Technical Field
The utility model relates to a tunnelling equipment technical field especially relates to a rocking arm formula entry driving machine.
Background
In order to effectively develop coal resources, an underground roadway needs to be tunneled, wherein tunneling means that coal and rock are crushed in a coal and rock body by certain technology and means to form the roadway and effectively support the roadway space.
At present, coal roadway excavation in China faces the problems of low roadway forming speed, low level of mechanization and automation and the like. The contradiction between the working face stoping speed and the roadway forming speed leads to the tension of mining continuation, and further improvement of scientific coal yield is hindered.
The coal mine tunnel boring machine mainly has three forms, namely a cantilever type boring machine, a drum type boring machine and a full-face boring machine.
The boom-type roadheader is represented by EBZ series (e.g., EBZ160) manufactured by shanxi tianjikui coal equipment ltd. The cantilever type heading machine is a main machine type for coal roadway heading at present, but has the problems of longer cantilever, overlarge occupied space and the like. Secondly, the cantilever type excavator needs to move the machine body left and right in the tunneling construction of the roadway to realize the cutting of the full section of the roadway, the work is long in time consumption, and the improvement of the tunneling efficiency is hindered.
The drum-type heading machine does not need to move the machine body left and right in the heading operation, can realize the cutting of the roadway section in situ, and has a typical machine type of MB670 of Sandvik company. The cutting mode of the machine type faces the following problems in actual construction: (1) the roller is long, the cutting resistance is large, the power requirement on the development machine is high, the development is difficult when the fault and the rock stratum are met, and the adaptability to different rock strata is poor; (2) the horizontal roller can not adjust the angle, and the roller cutting mode is difficult to meet the tunneling construction working condition of the inclined roof roadway; (3) the drum-type cutting mode has the advantages that the cutting mechanism is long, the disturbance to the top plate is large in the cutting process, and the top plate is easy to collapse.
The full-face tunneling machine is relatively few in application and is still in a research and development test stage, and typically, the full-face rectangular tunneling machine MJJ 3800X 5800 developed by Shanghai research institute of China coal science and engineering group is available. The cutting mechanism of the full-face tunneling machine can cut and propel the full face of the roadway at one time. The full-face heading machine has the following problems in coal mine tests: the whole machine is heavy and is difficult to adapt to the conditions of a soft or large-gradient bottom plate in a coal mine; secondly, a certain cutting blind area usually exists during full-section cutting; thirdly, the resistance of full-section propulsion is very large, and when the full-section propulsion meets rocks, the situation that the propulsion cannot be performed often exists; fourthly, the direction of the full-face cutting mechanism is difficult to control, and the deviation of the tunneling direction is easy to cause; fifthly, when the section is cut, the tunneling head is closed, and carbon monoxide or gas is easy to exceed the limit.
The tunneling equipment and the tunneling process are one of key factors influencing the tunneling speed and the tunneling efficiency of a roadway, wherein the design and the construction process of the cutting mechanism are main factors influencing the tunneling speed and the tunneling efficiency.
In summary, the current mainstream roadheader models face a variety of problems that severely impede the further development of rapid roadheader. For example: the cantilever type heading machine has the problems of low heading speed, overlarge empty-roof distance, insufficient supporting space, small number of integrated drilling machines on the machine body and the like. The roller type heading machine has the problem of poor adaptability.
