Description

Reversible sliding anchor drill platform Technical Field The utility model relates to the technical field of coal mine roadway support, in particular to a reversible sliding anchor drilling platform. Background The tunneling and anchoring integrated rapid tunneling technology represents the international advanced level of the current coal roadway tunneling field, and the tunneling efficiency and the safety performance are remarkably improved through the technical characteristics of parallel tunneling, supporting, breaking, transporting, full-width cutting and the like. The technology system suitable for stable and medium stable surrounding rock conditions is successfully developed in China. However, under weak surrounding rock conditions such as 'three soft' (soft bottom plate, soft top plate and soft side wall) stratum, the technology faces the serious challenge that large-area caving and even top plate caving accidents are extremely easy to be induced by overlarge empty top distances and empty side wall distances. At present, two core technologies for the complex conditions, namely small space roof distance instant support and roadway side stability control, have not yet been completely broken through. Particularly for low roadways, the space limitation and the technical difficulty of the supporting operation are further increased, and higher requirements are put on the supporting technology. The key dilemma of the current support link is that anchor bolt support needs to be implemented in the whole width range of the heading head, but the installation structure of the existing fixed drilling machine has the remarkable defects that any position in the width direction of the roadway cannot be flexibly covered, support dead areas exist to prevent instant support, the fixed drilling machine is difficult to effectively push the drilling machine to the forefront end of the heading head to cause support lag, particularly in a narrow space of a low roadway, the drilling machine is difficult to arrange, the anchor bolt support operation is inconvenient, the drilling machine is difficult to fully support the drilling machine upwards to a top plate by the existing structure, and the support efficiency is greatly limited. In summary, the existing fixed drilling machine structure generally has the problems of insufficient freedom and limited adaptability, and is characterized in that the drilling machine is limited in arrangement space, has a supporting blind area and is inconvenient to operate. Especially under the condition of weak surrounding rock with low roadway and small space roof distance, the working capacity of the method is seriously insufficient. Therefore, there is a need to develop a new type of reversible slide anchor drilling platform to break through the bottleneck in the prior art. Disclosure of Invention The utility model provides a turnover type sliding anchor drilling platform, which aims to solve the problems that the existing fixed drilling machine structure is insufficient in degree of freedom and limited in adaptability, and is particularly limited in drilling machine arrangement space, inconvenient in supporting blind areas and anchor rod supporting operation, and particularly seriously insufficient in operation capability under the condition of weak surrounding rock with low roadway and small air jacking distance. In order to achieve the above object, the technical scheme of the present utility model is as follows: The turnover sliding anchor drill platform comprises a lower layer fixed platform assembly and an upper layer sliding platform assembly, wherein the lower layer fixed platform assembly comprises a left anchor protection fixed platform and a right anchor protection fixed platform, the upper layer sliding platform assembly comprises a left anchor drill platform and a right anchor drill platform, and two groups of top anchor devices and one group of upper anchor devices are arranged on the left anchor drill platform and the right anchor drill platform. The upper layer anchoring device realizes small angle adjustment in the front-back and left-right directions, can turn forward for 90 degrees to realize large angle adjustment, so that the anchoring device is positioned in an empty top area at the upper end of the cutting part, and the upper layer upper anchoring device realizes support of the side wall, can adapt to different row spacing construction and ensures the construction range and angle of the anchor bolt support. Further, the left anchor protection fixing platform and the left anchor drilling platform, and the right anchor protection fixing platform and the right anchor drilling platform are all connected through a pushing oil cylinder. The propulsion oil cylinder stretches and contracts to drive the upper sliding platform assembly to integrally slide along the tunneling direction. Further, the anchoring device comprises an anchoring drilling machine fixed on the anchoring c
