Description

Simultaneous space-time quick anchoring equipment for TBM tunneling in coal mine Technical Field The invention relates to the technical field of fully-mechanized roadway anchoring, in particular to simultaneous and space-time rapid anchoring equipment for TBM tunneling of a coal mine. Background With the extension of coal resource exploitation to deep and complex geological condition areas, full-face hard rock Tunnel Boring Machines (TBMs) are increasingly applied to coal mine tunnel construction. However, the traditional TBM tunneling and roadway support process has the obvious space-time separation problems that the TBM tunneling is stopped, anchoring operation is completed by manual or simple equipment, the process connection efficiency is low (the support time is about 30% -50% of the cyclic operation), the equipment utilization rate is reduced (the TBM stopping waiting rate reaches 40%), and the efficient tunneling of the coal mine is severely restricted. Therefore, a safe, efficient, reliable and quick anchoring mode is developed, tunneling and supporting construction processes are improved, and roadway forming effects are improved. In recent years, the research and development of intelligent equipment for fully-mechanized excavation working faces inputs a large amount of manpower and material resources in the field of excavation equipment, makes a great breakthrough, basically realizes the automatic operation of the excavation equipment, and greatly improves the excavation speed and efficiency. But in contrast the development of the anchoring equipment is slow. At present, the anchoring equipment is manually operated under the condition of tunneling suspension. Aiming at the problems, attempts are made at home and abroad to adopt the schemes of folding drill booms or rear support platforms and the like, but the problems of influencing tunneling efficiency, being slower in anchoring operation and the like exist. The problems of more manual operation steps, high labor intensity, low supporting speed and the like become main factors for restricting the propelling and accelerating of the working surface. Therefore, development of a rapid anchoring device for synchronous operation with TBM tunneling is needed, and through structural integration, operation intellectualization and control coordination, a barrier that tunneling and supporting cannot work simultaneously is broken through, so that double improvement of the construction efficiency and safety of a coal mine tunnel is realized. In order to solve the above problems, represented by the patents "CN119860250a", "CN118757196a" and "CN116658218A", in order to improve the efficiency and convenience of the anchoring operation, the device solves the problem of low anchoring operation efficiency by increasing the number of jumbolters and changing the working angle, arrangement and use modes of the jumbolters. Such a solution generally achieves an increase in the overall tunneling rate, however, its drawbacks still limit the development of the anchoring equipment, affecting the tunneling efficiency of the tunneling machine, as follows: 1) Using single bit sequential operations According to the using scheme of the jumbolter of the TBM anchoring equipment, the number of the jumbolters is far smaller than the number of required holes, so that the drilling machine needs to be moved for a plurality of times to complete one-time support, the time required by single cycle is long, the TBM can be tunneled for multiple rings in the same time period, the speed is seriously mismatched, and the tunneling efficiency is influenced. 2) Using staged operation The above-mentioned disclosed coordination mode of jumbolter and TBM tunneling still does not change the factor that affects tunneling speed most, and although the disclosed patent claims "integration", more stay at the structure combination level, actually do not reach real time synchronization, but adopt stage operation (TBM tunneling-shut down-anchor operation-TBM tunneling), time consuming for every switching, unable to realize real synchronization, a large amount of time is wasted on procedure switching. Therefore, the scheme provides the simultaneous space-time rapid anchoring equipment for TBM tunneling of the coal mine. Disclosure of Invention The simultaneous space-time rapid anchoring device for TBM tunneling of the coal mine has the advantages of high tunneling and anchoring efficiency, flexible movement and convenient operation, and provides a solution for the background technology. In order to achieve the above purpose, the present invention adopts the following technical scheme: The simultaneous and time quick anchoring equipment for TBM tunneling of the coal mine comprises a machine body, wherein an anchor rod machine unit bracket is arranged on the machine body, a track sliding device is arranged between the anchor rod machine unit bracket and the machine body so as to enable the anchor rod machine uni
