Description

Technical Field

[0001] This utility model is an anchor bolt construction device, belonging to the field of anchor bolt construction. Background Technology

[0002] In geotechnical engineering, mining, and tunnel construction, anchor bolt support is a key technical means to ensure the stability of engineering structures. By embedding anchor bolts deep into the rock strata or soil, the integrity and bearing capacity of the surrounding rock can be effectively improved, preventing geological disasters such as collapses and landslides. Therefore, the quality and efficiency of anchor bolt construction directly affect the safety and progress of the entire project.

[0003] With the continuous expansion of engineering construction scale and the increasing complexity of construction environments, higher requirements are placed on the performance of anchor bolt construction devices. Traditional anchor bolt construction equipment usually uses a direct motor drive for angle adjustment, lacking an intuitive angle display structure. Operators cannot grasp the actual angle status of the anchor bolts in real time, which easily leads to angle deviation. Moreover, this drive method does not have a self-locking function. During drilling, due to the reaction force of rock strata or soil and the influence of the equipment's own vibration, the angle is prone to shift, resulting in borehole deviation. This deviation is further amplified under complex geological conditions. For example, in projects that require the formation of a mesh support structure, insufficient angle matching accuracy between anchor bolts will lead to uneven stress distribution in the support system, significantly reducing the overall support strength. At the same time, because the angle information is not intuitive, subsequent calibration work is also extremely inconvenient, often requiring multiple stops for measurement and adjustment, seriously affecting the construction progress. Therefore, it is necessary to design an anchor bolt construction device. Utility Model Content

[0022] Please see Figure 1 and Figure 2 The lifting frame 7 has a rectangular frame design, and lifting slots 701 are provided on both sides of the vertical plates. Screws 702 are rotatably connected to the lifting slots 701. A third servo motor 703 is installed at the center of the bottom of the lifting frame 7.

The threaded connection between the threaded ring 801 and the limiting ring 802 facilitates the adjustment of the position of the limiting ring 802 according to the specifications of the anchor rod 9. The setting of the second balls 803 reduces the friction between the anchor rod 9 and the limiting ring 802 when the anchor rod 9 rotates, ensuring smooth rotation of the anchor rod 9. At the same time, the limiting ring 802 limits the anchor rod 9, preventing the anchor rod 9 from shaking during drilling and improving drilling accuracy.

[0025] Detailed Implementation: When in use, power is connected, the base plate 1 is mounted on the engineering vehicle, and moved to the construction position. The first servo motor 406 drives the first worm gear 405, which in turn drives the drive worm wheel 404 and drive rod 403 to rotate, causing the first rotating assembly 4 to rotate 360° in the horizontal plane. The horizontal angle is determined by the angle dial 201 and the pointer 4081. The second servo motor 505 is then activated, and the second worm gear 504 engages with the worm wheel teeth 5031 of the connecting sleeve 503, causing the second rotating assembly 5 to rotate vertically. Rotating from -10° to 150° in a straight plane, the vertical angle is calibrated by the scale line 5021 of the anti-detachment ring 502 and the opening 4021 of the limiting sleeve 402. The third servo motor 703 drives the lead screw 702 through the sprocket mechanism, which drives the mounting plate 6 to rise and fall along the lifting groove 701 of the lifting frame 7 to adjust the drilling depth of the anchor rod 9. The rotary motor 10 drives the anchor rod 9 and the drill bit 12 to rotate through the mounting sleeve 11. The limiting ring 802 of the positioning component 8 and the second ball bearing 803 assist the anchor rod 9 to drill stably.
