[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] See Figures 1-4 An automatic core drilling machine support includes a base 1, which is rectangular in structure. U-shaped frames 2 are inclined upwards on both sides of one end of the base 1. Each U-shaped frame 2 has a movable wheel 3. When the base 1 is horizontal, the lower side of the movable wheel 3 is higher than the ground. A mounting groove 4 is fixedly provided on the upper surface of the base 1, welded to the base 1. The side of the mounting groove 4 facing away from the movable wheel 3 is open, while the upper end of the other side has a downward-facing groove for a support column 5 to pass through. A support column 5 is hinged to the mounting groove 4 via a pin 16. An adjustable angle is provided between one side of the support column 5 and the upper surface of the base 1. Angle adjustment component 6 is provided. A lifting component 7 is provided on the outer periphery of the support column 5. A vertical plate 8 is detachably provided on the side of the lifting component 7 away from the moving wheel 3 by bolts. A core drilling machine mounting plate 9 is horizontally connected to the lower part of the vertical plate 8. A rubber pad 17 is fixedly connected to the bottom surface of the base 1. The rubber pad 17 is provided to enhance the friction between the base 1 and the ground and to minimize the displacement of the base 1 during drilling. A counterweight area is provided on the base 1 between the mounting groove 4 and the moving wheel 3. The counterweight area can be used to place counterweight blocks or local stones as counterweights to strengthen the weight of the entire support and prevent displacement during drilling.

[0019] The preferred lifting assembly 7 includes a rotary cylinder 701, a lifting screw 702, a lifting frame 703, a sleeve 704, and a connecting block 705. The supporting column 5 has a hollow structure, and elongated through slots 10 are respectively opened on both sides of the supporting column 5 along its height direction. The upper and lower ends of the lifting screw 702 are rotatably connected to the upper and lower sides inside the supporting column 5, respectively. The rotary cylinder 701 is fixedly installed on the top surface of the supporting column 5, and its output shaft is connected to the top of the lifting screw 702. The rotary cylinder 701 is energized by an external power source. The lifting frame 703 is sleeved on the outside of the supporting column 5. The lifting frame 703 has a frame structure and is close to... A groove is also provided on one side of the moving wheel 3. A sleeve 704 is fitted on the lifting screw 702. The two sides of the sleeve 704 pass through the through groove 10 through connecting blocks 705 and are fixedly connected to the lifting frame 703. The two sides of the connecting blocks 705 slide against the two sides of the through groove 10 to ensure the stability of the lifting frame 703 during the up and down movement. The core drilling machine mounting plate 9 is set on the lifting frame 703 on the side away from the moving wheel 3. In specific use, the starting rotary cylinder 701 is controlled to drive the lifting screw 702 to rotate, which in turn drives the sleeve 704 to move up and down along the lifting screw 702 to drive the lifting frame 703 to move.

[0020] The preferred lifting assembly 7 further includes a pulley assembly 706, a slide rail 707, and a slider 708. The pulley assembly 706 is symmetrically arranged between the lifting frame 703 and the support column 5 on the side of the moving wheel 3 along its height direction. The support column 5 on the side of the core drilling machine mounting plate 9 is provided with a slide rail 707 along its height direction. The lifting frame 703 is provided with a slider 708 that can slide up and down on the slide rail 707. The arrangement of the pulley assembly 706, the slide rail 707, and the slider 708 reduces the friction between the inner side of the lifting frame 703 and the support column 5 during the up and down lifting process.

[0021] The preferred angle adjustment assembly 6 includes two adjusting screws 601, an adjusting sleeve 602, and an adjusting rocker 603. The two adjusting screws 601 are rotatably connected to the upper part of the support column 5 and the base 1 on the side near the moving wheel 3, respectively, via mounting ears. The two adjusting screws 601 are mirror screws. The adjusting sleeve 602 is sleeved 704 on the free ends of the two adjusting screws 601. The adjusting rocker 603 is fixedly connected to both sides of the adjusting sleeve 602. In use, simply rotating the adjusting rocker 603 will cause the adjusting screws 601 on both sides to move relative to each other, thereby adjusting the angle between the support column 5 and the base 1, thus satisfying the support of the core drill when drilling at an inclined angle.

[0022] The preferred support column 5 has a handrail 11 fixedly connected to the top of the side near the moving wheel 3. The handrail 11 not only helps the stability of the support when drilling, but also makes it easier to drag the support.

[0023] The preferred base 1 is detachably provided with a connecting frame 12 on the side away from the moving wheel 3. A limiting ring 13 is horizontally provided on the connecting frame 12. The limiting ring 13 is located directly below the core drilling machine mounting plate 9. The setting of the limiting ring 13 can ensure the stability of the drill pipe during drilling. It is worth noting that when drilling at an inclined angle, the connecting frame 12 needs to be removed to avoid the limiting ring 13 blocking the drill pipe.

[0024] The preferred mounting groove 4 and the movable wheel 3 have a long bolt through groove 14 on the base 1. When it is necessary to drill holes in the wall or bridge pier, the base 1 can be fixed to the wall or bridge pier by bolts, which is more practical.

[0025] The preferred mounting groove 4 has reinforcing ribs 15 welded to both sides of the groove 14 away from the bolt, which effectively enhances the stability of the mounting groove 4.

[0026] The working principle of this utility model: First, determine whether the drilling location is on the ground or on a higher wall or bridge pier. When the drilling location is on the ground, simply place the support on the ground and adjust the tilt angle of the support column 5 as needed. To adjust the angle, simply rotate the adjusting rocker 603. At this time, the two adjusting screws 601 move relative to each other, thereby adjusting the angle between the support column 5 and the base 1. Then, place heavy objects such as stones in the counterweight area as counterweights to enhance the stability of the support and begin drilling. When the core drill provides power to the drill pipe, control the start lifting cylinder 701 as the drill pipe gradually drills downwards. This drives the lifting screw 702 to rotate, which in turn drives the sleeve 704 to move downwards along the lifting screw 702, thereby moving the lifting frame 703 to meet the drilling needs of the drill pipe. When the drilling depth is reached, control the start lifting cylinder 701 to reverse and drive the drill pipe to gradually move away from the ground. When drilling holes in a wall or bridge pier, first drill expansion bolt holes, then fix the base 1 in the bolt holes with bolts, and then adjust the angle by adjusting the adjusting screw 603 according to actual needs. Then follow the above operation steps.
