Description

; LU101997 | MECHANIZED WORKING FACE | Technical Field | The present invention relates to the field of electromechanical devices for fully . mechanized working faces, and specifically relates to a stepping anchor supporting robot .

for a fully mechanized working face, belonging to the scope of anchor supporting | intelligent devices. ; Related Art | In recent years, fully-mechanized excavating, anchoring and supporting devices have . developed rapidly, there are many products, and the operating efficiency has been greatly . improved than before. However, such devices generally bave the problem of limited | application range due to a large volume of the device. Furthermore, most of devices adopt Ë wheel type or crawler type moving solutions. Tires or crawlers working for a long time ; under relatively harsh environments of coal mine roadways are easy to damage and | difficult to repair. The weight of the complete set of device is increased due to huge . moving power components, so that there is a defect of subsidence during operating in soft ’ rock roadways. In addition, when an existing excavating, anchoring and supporting ; device performs an anchoring operation on a roadway, the paving of an anchor net mostly .

adopts manual operation, so that the working efficiency is not high, and there is a danger : of being hit by scattered rocks on a roof. ; At present, some products integrate an excavating machine and an anchor supporting | device together, and the traditional crawler type travelling mode is abandoned. The most | typical solutions are disclosed in the publication patent numbers CN201610119970.2, | CN201610119982.5, CN201810959282.6 and CN201810959588.1, in which stepping | cooperation is realized by enabling an excavating supporting part and an anchoring ; supporting part to alternately move forward. The problem that the machine body falls into |} the roadway floor due to an excessive grounding ratio is solved by increasing the contact | area between the machine body and the roadway floor, so that the device is suitable for | soft and hard complicated roadways. Moreover, a stability increasing and vibration |

2 LU101997 | reducing structural part is disposed between the excavating supporting part and the | anchoring supporting part, so that the connection between the excavating supporting part | and the anchoring supporting part is tighter, the overall structural stability is higher, the . vibratory magnitude of a stepping excavating, supporting and anchoring integrated | machine set in the process of cutting coals and rocks is improved, and the excavating . efficiency and the safety are further increased.

Although such solutions solve the common ‘ problems of the wheel type or crawler type excavating, anchoring and supporting device, | the device has higher requirements for the roadway floor and the moving process is not | flexible enough, which is specifically as follows: |

1) The device has higher requirements for the flatness of the roadway floor. ‘ In the solutions mentioned in the above patents, when an excavating component is ; supported, an anchoring component moves back and forth, and when the anchoring | component is supported, the excavating component moves back and forth.

The processes ;

are repeated alternately to realize the movement of the complete set of device.

However, ’

there is a large friction resistance between the moving component and the roadway floor, f and obviously, the more uneven the roadway floor, the larger the friction resistance.

À Therefore, the use of the device has strict requirements for the gradient and flatness of the Î roadway, and the device is not suitable for roadways with relatively harsh environments. ;

2) The device is poor in turning performance and not flexible in moving process. |

In the solutions mentioned in the above patents, the creeping movement of the device , is realized by means of the alternating movement of the excavating supporting part and | the anchoring supporting part.

However, due to the larger volume of the excavating | component and the anchoring device, the magnitude of turning of the complete set of | device is very limited, a larger roadway space is required, and the moving process is very | slow, which affects the excavating and anchoring speed of the complete set of device. | 3) The degree of automation of the anchoring process is not high. |

In the above patents, the paving of an anchor net on the roadway roof in the anchoring | operation requires manual operation by workers, the working environment is harsh in this | process, the manual operation has large labor intensity and low working efficiency and | seriously affects the speed of the anchoring operation, and the workers are at risk of being | hit by scattered rocks on the roadway roof, l SUMMARY |
