Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction equipment, in particular to a crank-arm type spiral anchor drilling machine for temporary anchoring. Background Art

[0002] The spiral anchor foundation is a new form of transmission line tower foundation. No foundation pit excavation is required during the construction of the spiral anchor. The spiral anchor rod is rod-shaped with spiral blades at the end. The torque is applied through the anchor rod to screw the spiral blades into the deeper soil. The disturbance to the soil is small, and the inherent strength of the original soil can be fully utilized to improve the bearing capacity.

[0003] Temporary anchoring screw drills are used for small screw anchors and are suitable for applications such as fixed capstans, tensioners, steering blocks, and temporary cable pulleys. Drilling requires a precise tilt angle for the anchor, but the ground at the construction site is often difficult to achieve a horizontal angle. Once the driller's body is tilted after positioning, it can easily lead to errors in the drilling angle. Excessive errors can even cause serious deviations in the construction site, affecting the final construction results. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a curved arm type temporary anchoring spiral anchor drilling machine for the above-mentioned technical deficiencies, which can realize horizontal positioning of the vehicle body at different road angles, thereby avoiding construction errors caused by vehicle body tilt.

[0005] The technical solution adopted by the utility model is to provide a crank arm type temporary anchoring spiral anchor drilling machine, comprising a traveling vehicle driven by a power device; a hydraulic crank arm is connected to the traveling vehicle, and a drilling power assembly is connected to the free end of the hydraulic crank arm; a positioning adjustment assembly is provided in the traveling vehicle;

[0006] The drilling power assembly includes a hydraulic motor reducer connected to the free end of the hydraulic crank arm; the output end of the hydraulic motor reducer is coaxially fixed with a drilling anchor downward;

[0007] The positioning adjustment assembly includes a mounting opening opened at the bottom of the vehicle body; a supporting plate is correspondingly arranged in the mounting opening; an axle seat is fixed to the upper end of the supporting plate; an adjusting shaft is rotatably connected to the axle seat; the adjusting shaft is arranged parallel to the supporting plate; the adjusting shaft is driven by a first angle motor fixed on the axle seat; a support collar is coaxially rotatably sleeved on the middle part of the adjusting shaft; a supporting shaft is radially fixed to the outer wall of the supporting collar; a connecting frame is fixed inside the vehicle body; a telescope is fixed on the lower side of the connecting frame; the output end of the telescope is vertically downward and fixed with a positioning bracket; the support shaft is rotatably connected to the positioning bracket; the support shaft is driven by a second angle motor fixed on the positioning bracket; a spirit level for checking the horizontal state of the vehicle body is fixed on the vehicle body.

[0008] To further optimize this technical solution, a curved arm type temporary anchoring spiral anchor drilling machine has sliding rails fixed at the four corners of the upper end of the supporting plate along the diagonal direction of the supporting plate; and an expansion rod is slidably connected to the sliding rails.

[0009] To further optimize this technical solution, a support pad is fixed on one end of the expansion rod of a curved arm type temporary anchoring spiral anchor drilling machine, which is away from each other; the bottom end of the support pad is flush with the bottom end of the support plate.

[0010] To further optimize the technical solution, a plurality of grounding holes are provided on the supporting plate of a curved arm type temporary anchoring spiral anchor drilling machine.

[0011] The beneficial effects of the present invention are:

[0012] The movement of the hydraulic crank arm can adjust the drilling angle of the drilling anchor and apply the downward pressure required for the drilling anchor to drill; the hydraulic motor reducer can drive the drilling anchor to rotate, and by combining with the movement of the hydraulic crank arm, the drilling construction process at the designated position is realized.

[0013] The output end of the telescopic device is used to drive the support plate to move up and down vertically. The support plate moves downward to contact the ground, lifting and supporting the vehicle body. A support collar is coaxially connected to the middle of the adjustment shaft, and the support collar is radially fixed to the outer wall of the support collar. The second angle motor drives the support shaft to rotate a certain angle, which can cause the support collar to drive the adjustment shaft to swing a certain angle, thereby changing the tilt angle of the support plate. The first angle motor can drive the adjustment shaft to rotate a certain angle around the axis, changing the tilt angle of the support plate in another direction. By adjusting the tilt angle of the support plate in two directions, the angle of the vehicle body itself can be effectively adjusted when the support plate supports the ground, ensuring that the vehicle body can be in a horizontal position.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] like Figure 1 As shown, a crank arm type temporary anchoring spiral anchor drilling machine includes a traveling vehicle 1 driven by a power device 2; a hydraulic crank arm 3 is connected to the traveling vehicle 1, and a drilling power assembly is connected to the free end of the hydraulic crank arm 3; a positioning adjustment assembly is provided in the traveling vehicle 1;

[0020] like Figure 1 As shown, the drilling power assembly includes a hydraulic motor reducer 4 connected to the free end of the hydraulic crank arm 3; a drilling anchor 5 is coaxially fixed downwardly at the output end of the hydraulic motor reducer 4;

[0021] like Figure 1-3 As shown, the positioning adjustment component includes a mounting opening 6 opened at the bottom of the body 22 of the traveling vehicle 1; a supporting plate 7 is correspondingly provided in the mounting opening 6; an axle seat 8 is fixed to the upper end of the supporting plate 7; an adjusting shaft 9 is rotatably connected to the axle seat 8; the adjusting shaft 9 is arranged parallel to the supporting plate 7; the adjusting shaft 9 is driven by a first angle motor 10 fixed on the axle seat 8; a support collar 11 is coaxially sleeved on the middle part of the adjusting shaft 9; a support shaft 12 is radially fixed to the outer wall of the support collar 11; a connecting frame 13 is fixed inside the body 22; a telescope 14 is fixed to the lower side of the connecting frame 13; the output end of the telescope 14 is vertically downward and fixed with a positioning bracket 15; the support shaft 12 is rotatably connected to the positioning bracket 15; the support shaft 12 is driven by a second angle motor 16 fixed on the positioning bracket 15; the first angle motor 10 and the second angle motor 16 can be stepper motors or servo motors, which are convenient for precise control of the angle; a spirit level 17 for checking the horizontal state of the body 22 is fixed on the body 22.

[0022] The drilling anchor 5 has corresponding requirements for the inclination angle of the anchor hole drilled to the ground, and the inclination angle is set based on a horizontal reference. Therefore, to ensure that the inclination angle of the drilled anchor hole meets the requirements, the most convenient way is to position the vehicle body 22 itself to a horizontal angle. However, the construction ground cannot be in an ideal horizontal state, and even the ground of many construction sites has a significant inclination angle. If the ground is repaired to a horizontal state before drilling, it will consume time and effort and affect the drilling efficiency.

[0023] In the technical solution, the ground does not need to be leveled. Instead, the support plate 7 is used to appropriately lift the vehicle body 22. Then, the angle between the support plate 7 and the vehicle body 22 is adjusted while the support plate 7 is supporting the ground. Even if the ground is inclined, the vehicle body 22 can be easily adjusted to a horizontal position without the need to repair the ground, greatly saving time and labor and improving construction efficiency.

[0024] Specifically, the support plate 7 is pushed down to contact the ground by the extension of the extender 14. Then, the support plate 7 is adjusted to fit the ground by the action of the first corner motor 10 and the second corner motor 16. Since the support shaft 12 is perpendicular to the adjustment shaft 9, the inclination angle of the support plate 7 can be adjusted in all directions by rotating the adjustment shaft 9 with the first corner motor 10 and rotating the support shaft 12 with the second corner motor 16, ensuring adaptation to the inclined ground. After the support plate 7 is adapted to support the ground and the vehicle body 22 is appropriately lifted, the angle of the vehicle body 22 relative to the support plate 7 is adjusted by the appropriate action of the first corner motor 10 or the second corner motor 16. Combined with the reference of the level 17 on the vehicle body 22, the vehicle body 22 can be adjusted to a horizontal angle.

[0025] After the vehicle body 22 is adjusted to a horizontal angle, the drilling angle of the drilling anchor 5 is controlled by the hydraulic curved arm 3, which ensures that the drilling inclination angle is accurate enough and improves the reliability of the construction.

[0026] As shown in Figure 2-3 The support plate 7 has a slide rail 18 fixed at each of the four corners of the upper end along the diagonal direction of the support plate 7. An expansion rod 19 is slidably connected to the slide rail 18. After the support plate 7 supports the ground, the expansion rod 19 is slid outward along the slide rail 18, which expands the support range and improves the stability of the support of the vehicle body 22.

[0027] As shown in Figure 3As shown, a support block 20 is fixed to one end of the expansion rod 19, which is away from each other; the bottom end of the support block 20 is flush with the bottom end of the support plate 7. After the expansion rod 19 slides outward, the support block 20 is supported by the ground, which can separate the expansion rod 19 from the ground by a certain distance, preventing the expansion rod 19 from being contaminated by debris and being dragged into the slide rail 18, which would prevent the expansion rod 19 from sliding smoothly along the slide rail 18.

[0028] like Figure 2-3 As shown, a plurality of grounding holes 21 are provided on the supporting plate 7. If the ground tilt angle is relatively large, in order to prevent the supporting plate 7 from slipping when supporting the ground, ground nails can be driven through the grounding holes 21 to ensure that the supporting plate 7 is firmly positioned on the ground.
