Multifunctional roadheader

Abstract

The invention discloses a multifunctional roadheader which comprises a body part and a walking part, wherein the walking part is installed on the body part; the body part is provided with a milling and digging part, a shovel plate part, an electric control box and a conveyer; the milling and digging part is positioned in front of the body part; the shovel plate part is positioned below the millingand digging part; an electric part comprises the electric control box and a motor pump; the electric control box controls the motor pump through cables; the motor pump drives the walking part and theconveyer to move; and digging mechanisms and pushing mechanisms are arranged on the two sides of the body part correspondingly. The multifunctional roadheader is favorable for realizing the front-back movement of a main machine on a slope of 30 degrees, and can select different mechanisms to assist the movement, tunneling and collection work according to different requirements in the environmentand the construction process, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tunneling in coal mines, in particular to a multifunctional tunneling machine. Background technique [0002] The roadheader is a large-scale mechanical equipment for tunneling in coal mines and non-coal mines. The traditional roadheader consists of a cutting part, a shovel part, a conveyor, a body part, a walking part, a hydraulic system and an electrical system. For different rock hardness, the roadheader has different cutting hardness and different equipment models. . The small cutting hardness is below 40MPa, the weight of the main engine is below 30 tons, the medium cutting hardness is below 60MPa, the main engine weight is below 55 tons, the large cutting hardness is below 100MPa, and the main engine weight is below 120 tons. The cutting hardness is different, and the cutting power is different, which leads to the great difference in the weight and size of the main machine. Therefore, for different...

Problems solved by technology

The small cutting hardness is below 40MPa, the weight of the main engine is below 30 tons, the medium cutting hardness is below 60MPa, the main engine weight is below 55 tons, the large cutting hardness is below 100MPa, and the main engine weight is below 120 tons. The cutting hardness is different, and the cutting power is different, which leads to the great difference in the weight and size of the main machine. Therefore, for different working conditions, it is difficult to choose an economical and reasonable model for different tunnel boring machines. At present, there is no one for small tunnel hard rock. This type of model can meet the needs of use, but for the uphill and downhill conditions of large slopes, the current working range of the roadheader is ±18 degrees, and the roadheader cannot work normally if it exceeds 18 degrees. The cut material cannot be exported, and it is more difficult to walk when encountering water
