Description

Technical Field

[0001] The utility model belongs to the field of coal mine fully mechanized mining equipment, in particular to a device for adjusting the frame inclination angle of a self-moving tail system. Background Art

[0002] With the development of mechanized fully-mechanized coal mining, the number of medium-thick and thick coal seams suitable for mining in mines has gradually decreased. However, my country's medium-thin coal seams are widely distributed. To ensure the sustainable utilization of resources, the mining of thin coal seams has become a hot topic for coal companies. The self-propelled tail is a key component of the working face chute transportation equipment. It is used to connect the bridge-type loader and conveyor, ensuring high production and efficiency of the working face.

[0003] Currently, the self-moving tail machine is relatively well-developed in medium-thick and thick coal seams, and will develop in both large-scale and small-scale directions in the future. Large-scale tail machines mainly meet the requirements of full-height mining in extra-thick coal seams, while small-scale tail machines meet the requirements of mining thin coal seams. With the improvement of the comprehensive mechanization level of coal mining, the development of self-moving tail machines will gradually achieve model and function serialization to meet the needs of different mining heights. At the same time, the automation of various functions of the self-moving tail machine will be gradually realized, including automatic adjustment of belt deviation, automatic forward movement of the tail machine chassis after a cycle of the transfer machine is completed, and automatic straightening of the tail machine's forward direction. The realization of these functions will change the working method of the self-moving tail machine, which must be operated by humans, and is one of the important technologies for unmanned coal face mining.

[0004] At present, a small number of thin coal seam working faces in China use single conveying equipment, without systematic consideration of the coordinated use of working face conveying equipment and chute conveying equipment. When developing thin coal seam working faces, due to the lack of dedicated thin coal seam chute transportation equipment, only low-height fully mechanized mining equipment is used, which increases the amount of top or bottom mining in the chute, resulting in a large amount of chute development work and high development costs. As a result, coal production efficiency and poor benefits are low, companies are reluctant to invest, and this also leads to low output and benefits for thin coal seam mining equipment manufacturers.

[0005] At present, the difficulties faced in the design and development of self-moving tail machines for thin coal seams are that the height of the self-moving tail machine device is difficult to lower, it is difficult to operate, and the self-moving tail machine frame itself is too heavy. These problems lead to substantial damage to the original occurrence state and continuity of coal seams below 2m or simple abandonment of thin coal seam resources. It also causes large resistance to movement of the self-moving tail machine and difficulty in operation. In order to ensure the safety and reliability of the self-moving tail machine design, most designs use two rows of oil cylinders on both sides, with about 20 cylinders, which makes pipeline layout difficult and uses heavier plates in structural design. Materials with good new functions, wide application range and low cost are not selected according to product functions and costs, resulting in cost waste. Utility Model Content
