[0022] In this embodiment, the driving assembly 1, the positioning cylinder 2, the manual assembly 3 and the locking assembly 4 constitute the main structure of the ground anchor device for deep rock and soil exploration involved in this application.

[0023] like Figure 1 and Figure 2 As shown, the hand-held frame 12 is configured as a rectangular frame structure, and hand-held rods are provided on both sides of the frame, and a connecting ring 11 is welded to the top of the frame, a connecting sleeve 14 is fixed to the lower side of the hand-held frame 12, and a driving shaft 15 is provided inside the connecting sleeve 14, and the upper end of the driving shaft 15 is connected to the output shaft end of the motor 13, and a cross block 16 is welded to the lower end of the driving shaft 15.

[0024] Through the above technical scheme, by setting the connecting ring 11, it is convenient to fix the external equipment that needs to be connected to the anchor device after the anchor rod 5 is fixed through the connecting ring 11; by setting the connecting sleeve 14 and the cross block 16 to slide and engage with the anchor rod 5, it is convenient to disassemble the drive assembly 1, and then to facilitate separation, transportation and subsequent disassembly and maintenance.

[0025] like Figure 1 As shown, the upper end of the positioning cylinder 2 is inserted into the connecting sleeve 14 and fixed by bolts, and an inner sliding cavity 21 is opened inside the positioning cylinder 2, and a sliding groove 22 is opened on the outer side of the inner sliding cavity 21, the anchor rod 5 is slidably connected in the inner sliding cavity 21, and a cross groove is opened at the top end of the anchor rod 5, and the cross groove is matched and clamped with the cross block 16.

[0026] Specifically, a spiral drill bit structure is provided at the lower end of the anchor rod 5 , and a cross notch is provided at the top end of the anchor rod 5 and extends downward along the length direction of the anchor rod 5 .

[0027] Specifically, during the process of the driven shaft 15 of the anchor rod 5 being driven to rotate, the cross block 16 initially contacts with the bottom of the cross slot, and then pressure is applied to the anchor rod 5 through the handheld frame 12 at the initial startup. When the drill bit part of the anchor rod 5 enters the underground rock and soil, downward drilling is achieved through the spiral structure of the drill bit itself. Before the anchor rod 5 contacts the ground and starts drilling, there is a gap between the bottom of the positioning tube 2 and the ground. Until the anchor rod 5 penetrates deep into the ground, the bottom of the positioning tube 2 contacts the ground, and then the anchor rod 5 continues to penetrate until the limit block is limited by the limit end at the bottom of the positioning tube 2, and at the same time, the contact surface between the upper side of the limit end and the limit block is set as a buffer pad.

[0028] like Figure 1 and Figure 4 As shown, a handle 32 is welded to the outer ring wall of the threaded ring 31, and an annular groove is opened on the lower end surface of the threaded ring 31, and a slider 34 is slidably connected in the annular groove, a slip ring 33 is connected to the lower end of the slider 34, and a first hanging ring 35 is connected to the lower end of the slip ring 33, the locking assembly 4 also includes a hinged ring 41 slidably connected to the outside of the anchor rod 5, and the outer wall of the hinged ring 41 is rotatably connected to the second connecting rod 45, and the outer end of the second connecting rod 45 is hinged to the outer wall of the fixed block 44, and a vertical threaded pile 43 is screwed inside the fixed block 44, and a limit block is fixed to the outer wall of the anchor rod 5, and the limit block is located on the lower side of the hinged ring 41.

[0029] Specifically, the slider 34 and the ring groove maintain a sliding and clamping state, thereby achieving a synchronous movement effect of the slip ring 33 and the threaded ring 31 .

[0030] Specifically, hooks are provided at both ends of the first connecting rod 42 , and a second hanging ring is provided at the top of the threaded pile 43 .

[0031] It should be noted that, after the anchor rod 5 is anchored to the set depth, the fixing block 44 is fixed, and then the height of the slip ring 33 is adjusted to connect the first connecting rod 42, and then the height of the slip ring 33 is adjusted to tighten the first connecting rod 42.

[0032] When in use, first point the lower end of the anchor rod toward the ground anchor point, then hold the handheld frame included in the handheld driving assembly, and then start the motor. The motor drives the driving shaft to drive the anchor rod to rotate, so that the anchor rod is drilled into the ground until the limit block on the anchor rod contacts the limit end at the bottom of the positioning tube. At this time, the fixed block is placed on the ground, and then the fixed block is fixed to the ground through a threaded pile. Then the threaded ring is rotated to drive the sliding ring to move, and at the same time, one end of the first connecting rod is hung on the second hanging ring at the upper end of the threaded pile. When the upper end of the first connecting rod is hung with the first hanging ring, the height of the sliding ring is adjusted again to keep the first connecting rod in a tensioned state, thereby achieving stable fixation of the anchor rod. Due to the triangular structure formed by the first connecting rod and the second connecting rod on the outside of the anchor rod, and the bottom of the second connecting rod is fixed to the ground through the fixed block, the installation firmness of the anchor rod is enhanced.
