Description

Technical Field

[0001] This invention belongs to the technical field of trackless auxiliary transportation machinery in coal mines, specifically relating to a conveying equipment with articulated wheel type advanced support for roadway installation and its usage method. Background Technology

[0002] Currently, advanced supports, as the main type of support for pre-support in roadways, are widely used in major mines across my country. The primary method for transporting advanced supports within roadways is the step-and-move self-propelled method. In recent years, with the introduction of alternating roadway support technology, monorail transport and winch-pulling methods have emerged. The step-and-move self-propelled support method uses a step-and-move support to achieve self-movement; however, due to limitations in step length, it requires repeated support of the roof during movement. For example, a 240m long advanced support requires repeated support of the roadway roof nearly 150 times. After repeated support from the roof beams, the roadway roof and the anchor-mesh cable support system are prone to roof damage and failure of the anchor-mesh cable support system, resulting in unstable roof support, severely affecting the effectiveness of advanced support, and posing significant safety hazards. Monorail transport and winch-pulling methods have greatly promoted the development of advanced support handling technology, but due to the complexity, low efficiency, and poor transport stability, the widespread application of these technologies and equipment has been hindered. Summary of the Invention
