Description

Technical Field

[0001] This utility model belongs to the technical field of slope reinforcement construction equipment, and specifically relates to a slope anchor drilling machine. Background Technology

[0002] Slope damage has become a significant geological hazard. The main engineering measures for its prevention and control include drainage, shoveling, and retaining structures (anchored grid beams, anchored retaining walls, and pile-slab walls). Among these, the use of anchors combined with other structures for slope retaining is the most widespread. During slope protection, anchors are drilled and then installed, utilizing the interaction between the anchors and the slope's soil and rock mass to enhance slope stability.

[0003] Chinese patent CN216665499U discloses a lateral drilling mechanism for an anchoring drill. A side-swing cylinder drives a side-swing head to rotate around the center of a rotary table (the stroke determines the angle), causing the drill frame to rotate accordingly. The cylinder stops when the rotation reaches 90 degrees. The extension and retraction of a compensating cylinder's telescopic rod adjusts the drill frame's tilt to regulate the anchor drilling angle. However, during drilling, it only performs ordinary drilling functions and cannot meet the need for enlarging anchor holes. Under heavy loads on the slope surface, this type of anchor often experiences increased deformation, or even pull-out of the anchor. Utility Model Content

[0016] A handle is also provided on one side of the slider.

[0017] A further embodiment is that the guide rail has a receiving cavity at one end near the connecting seat for placing a reaming drill bit, and a groove is formed on the periphery of the receiving cavity, and a sliding plate is provided in the groove for opening or closing the receiving cavity.

The installation and removal process is simple and quick, effectively reducing the time wasted on changing drill bits during construction. A receiving cavity on the guide rail is used to store the reaming drill bit, and the cavity can be easily opened and closed via a sliding plate. This prevents damage and loss caused by haphazard placement of drill bits on the construction site, enhances the convenience of drill bit management, helps ensure construction continuity, and reduces construction costs.

[0022] This invention, through the guide rail and slider structure on the connecting seat, combined with the handle on one side of the slider, makes the operation of the drive unit easier and more convenient. The operator can flexibly control the drilling speed and position of the drive unit by pushing the handle.
