Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of gob-side entry retaining and coal pillarless mining, and particularly relates to a narrow-body split roof beam end head anchor-avoiding support. BACKGROUND

[0002] The end head support is a key supporting device in the roadway retaining operation, and its performance directly affects the safety and production efficiency of the roadway retaining. At present, the roof beam width of the conventional end head support is designed according to the support width of the working face, and side guards are arranged on both sides of the roof beam. In actual application, in order to expand the effective supporting area and realize reliable support of the roof, the side guards are usually fully unfolded to meet the basic supporting requirements.

[0003] However, in the working face roadway retaining operation, in order to ensure the stability of the roof of the space to be poured and the construction safety, anchor rods (cables) need to be used for reinforced support, and the industry generally uses the front or rear setting mode, which exposes many problems that are difficult to avoid when cooperating with the conventional end head support. (1) If the anchor rod (cable) is set in front of the support, on the one hand, when the subsequent end head support moves forward, the support roof beam will cause extrusion damage to the anchor rod (cable) that has been set, resulting in invalidation of the early support, which needs to be re-set, thereby increasing the labor and material costs and prolonging the operation cycle; on the other hand, in order to ensure the safety of the setting operation, the working face needs to stop the production, which directly affects the overall mining efficiency.

[0004] (2) If the anchor rod (cable) is set behind the support, there are also obvious disadvantages: firstly, the working face still needs to stop production during the setting operation, and the efficiency loss problem has not been fundamentally solved; secondly, when the roof condition of the working face is poor, the lag setting mode is easy to cause the "net bag" phenomenon of the roof, which destroys the integrity of the roof and seriously threatens the support safety, thereby bringing major safety hazards to the underground operation.

[0005] (3) Although the conventional end head support is provided with an anchor-avoiding device, the support anchor rod (cable) that has been set in the roadway retaining roadway is still easy to be extruded and damaged, which is not conducive to maintaining the integrity of the roof support system.

[0006] In summary, in order to effectively solve the problem of setting the anchor rod (cable) between the supports of the end head support, avoid the extrusion damage of the anchor rod (cable) during the support moving process, ensure the integrity and stability of the support structure, and significantly improve the mining progress of the working face, it is urgent to develop a new type of end head support structure.

When it is necessary to support the top slab of the space to be poured during the project implementation process, the adjustment mechanism 5 is used to push the end support of the narrow split top beam to a suitable distance and lock it. Anchor rods (cables) are installed in the middle of the split top beam 101 of the end support of the narrow split top beam. If the anchor rods (cables) 8 are densely distributed, the side guard plate is designed to be arranged in sections, and the side guard adjustment cylinder 402 is controlled in sections to ensure the recovery of the section side guard plate and achieve the purpose of installing the anchor rods (cables) 8.
