Description

Technical Field

[0001] The present invention relates to a punching device, and particularly to a punching device for the connecting bolt holes between the photovoltaic support column and the helical pile barrel. Background Art

[0002] When constructing a photovoltaic power generation field on a hillside or the slope protection of a highway, the photovoltaic power generation component support is generally arranged on a helical pile foundation. On the pile barrel of the helical pile foundation above the ground, there are generally reserved holes on the side wall of the helical pile barrel for connecting the photovoltaic column. When installing the photovoltaic support, the photovoltaic support column is inserted into the helical pile barrel, and bolts are inserted through the bolt through-holes reserved on the photovoltaic support column and the holes reserved on the side wall of the helical pile barrel. The photovoltaic support column and the helical pile barrel are fixedly connected together through the connecting bolts, thus completing the fixed installation of the photovoltaic support on the helical pile foundation. However, due to the variable slopes of the slopes and various uncertain factors in on-site installation, it often causes the reserved holes on the photovoltaic support and the holes reserved on the side wall of the helical pile barrel to be misaligned, and it is necessary to re-drill the bolt through-holes on the photovoltaic support column inserted into the helical pile barrel on-site. How to develop a drilling device that can adapt to the on-site slope installation environment and is convenient for operators to operate has become a problem that needs to be solved on-site. Summary of the Invention

[0003] The present invention provides a drilling device for the connecting bolt holes between the photovoltaic support column and the helical pile barrel, and solves the technical problem of how to develop a drilling device that can adapt to the on-site slope installation environment and is convenient for on-site drilling operation.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A drilling device for the connecting bolt holes between the photovoltaic support column and the helical pile barrel includes a helical pipe pile barrel. A photovoltaic support column is inserted into the upper port of the helical pipe pile barrel. A pair of bolt through-holes are arranged on the barrel wall of the helical pipe pile barrel above the ground. A box-shaped steel bar frame is arranged on the left side of the helical pipe pile barrel. A lower arc-shaped hoop plate support cantilever rod is arranged on the lower horizontal frame of the right port-shaped frame of the box-shaped frame. A lower arc-shaped hoop plate is connected to the outer end of the lower arc-shaped hoop plate support cantilever rod. A triangular frame-shaped cantilever bracket is arranged on the front vertical frame of the right port-shaped frame of the box-shaped steel bar frame. An upper arc-shaped hoop plate is arranged at the outer end of the triangular frame-shaped cantilever bracket. The box-shaped steel bar frame is horizontally suspended and clamped on the helical pipe pile barrel through the lower arc-shaped hoop plate and the upper arc-shaped hoop plate. A box-shaped sleeve frame that can move horizontally left and right is movably arranged on the box-shaped steel bar frame. An electric drill is fixedly arranged in the box-shaped sleeve frame, and the drill bit of the electric drill is movably abutted in the bolt through-hole.

[0006] The horizontal crossbeam sleeve of the box-shaped sleeve frame is movably sleeved on the horizontal crossbeam steel bars of the box-shaped steel bar frame, enabling the box-shaped sleeve frame to move left and right along the horizontal crossbeam of the box-shaped steel bar frame.

[0007] On the lower vertical frame of the U-shaped frame at the left end of the box-shaped frame, a rack through-frame column is fixedly connected. At the top of the rack through-frame column, a rack through-frame is connected. A horizontally arranged rack is movably arranged in the rack through-frame, and the right end of the rack is fixedly connected to the left end of the electric drill. A gear central axis support cantilever frame is fixedly connected to the rack through-frame. Gear central axis support bearings are arranged at the two outer ends of the gear central axis support cantilever frame. The central axis of the gear is arranged in a pair of gear central axis support bearings, and the gear meshes with the rack. Pins are arranged on the outer shells of the pair of gear central axis support bearings, and a swing arm rod is movably connected to the pins. A gear push claw is connected to the swing arm rod, and the gear push claw is in movable abutting cooperation with the teeth on the gear.

[0008] A method for drilling and punching the bolt holes connecting the photovoltaic support column and the screw pile barrel, characterized by including the following steps:

[0009] First step: Hook the triangular frame-shaped cantilever support on the right side of the box-shaped steel bar frame onto the screw pipe pile barrel above the ground, and clamp the lower arc-shaped clamping plate and the upper arc-shaped clamping plate on the screw pipe pile barrel, so that the box-shaped steel bar frame is horizontally suspended on the screw pipe pile barrel. Adjust the height of the box-shaped steel bar frame so that the drill bit of the electric drill is aligned with a pair of bolt through-holes.

[0010] Second step: Connect the power supply of the electric drill, swing the swing arm rod counterclockwise. The gear push claw connected to the swing arm rod abuts against the teeth on the gear, causing the gear to rotate counterclockwise. The gear drives the rack to move to the right through meshing with the rack, and the rack drives the electric drill to move to the right, so that the drill bit enters the bolt through-hole and drills the photovoltaic support column inserted in the screw pipe pile barrel.

[0011] Third step: Swing the swing arm rod clockwise, and the gear push claw connected to the swing arm rod disengages from the teeth on the gear. At this time, the movement of the rack and the electric drill to the right stops.

[0012] Fourth step: Swing the swing arm rod counterclockwise again. The gear push claw connected to the swing arm rod abuts against the teeth on the gear again, causing the gear to rotate counterclockwise. The gear drives the rack to move to the right again through meshing with the rack, realizing further movement of the drill bit to the right for drilling.

[0013] Fifth step: Repeat the steps from the second step to the fifth step until the top of the drill bit emerges from the right hole of a pair of bolt through-holes, and then turn off the power supply of the electric drill, thus completing the drilling of the bolt through-holes on the photovoltaic support column.

[0014] Step 6: Swing the swing arm rod clockwise to disengage the gear pushing claw connected to the swing arm rod from the teeth on the gear; move the box-shaped sleeve frame to the left to completely withdraw the drill bit from the drilled bolt through-hole; remove the box-shaped steel bar frame from the spiral pipe pile cylinder.

[0015] In the present invention, a box-shaped steel bar frame for supporting an electric drill is hung on a spiral pipe pile cylinder above the ground. A box-shaped sleeve frame that can move left and right is provided on the box-shaped steel bar frame, and the electric drill is fixed in the box-shaped sleeve frame, thereby overcoming the defect of uneven ground. In the form of a suspended platform, accurate drilling of the through-hole for the connecting bolt between the spiral pipe pile cylinder and the photovoltaic support column is achieved, improving the on-site work efficiency and reducing the construction cost.

[0021] The present invention will be described in detail below with reference to the drawings:

[0022] A drilling device for the bolt holes connecting the photovoltaic support column and the screw pile barrel, comprising a screw pipe pile barrel 1. A photovoltaic support column 2 is inserted into the upper port of the screw pipe pile barrel 1. A pair of bolt through holes 3 are provided on the barrel wall of the screw pipe pile barrel 1 above the ground. Due to the diverse changes in the slope of the slope, it is necessary to adjust the height of each photovoltaic support, resulting in the need to re-drill the bolt through holes on the photovoltaic support column 2 inserted into the screw pipe pile barrel 1. Because the ground outside the screw pipe pile barrel 1 is uneven and the bolt through holes are relatively close to the ground, it is difficult to place the electric drill on the ground or operate it manually. The present invention constructs a temporary operation horizontal platform suspended on the screw pipe pile barrel 1, places the electric drill on the temporary operation horizontal platform, ensures the accurate drilling of the bolt holes, and is convenient for on-site operators to operate. The specific structure of the temporary operation horizontal platform is as follows: A box-shaped steel bar frame 4 is suspended on the left side of the screw pipe pile barrel 1. A lower arc-shaped hoop plate support cantilever rod 5 is provided on the lower cross bar of the right port-shaped frame of the box-shaped frame 4. At the outer end of the lower arc-shaped hoop plate support cantilever rod 5, a lower arc-shaped hoop plate 6 is connected. A triangular frame-shaped cantilever bracket 7 is provided on the front vertical bar of the right port-shaped frame of the box-shaped steel bar frame 4. An upper arc-shaped hoop plate 8 is provided at the outer end of the triangular frame-shaped cantilever bracket 7. The box-shaped steel bar frame 4 is horizontally suspended and clamped on the screw pipe pile barrel 1 through the lower arc-shaped hoop plate 6 and the upper arc-shaped hoop plate 8; A box-shaped sleeve frame 16 that can move horizontally left and right is movably arranged on the box-shaped steel bar frame 4. An electric drill 17 is fixedly arranged in the box-shaped sleeve frame 16. The drill bit 18 of the electric drill 17 is movably abutted against the bolt through hole 3. By horizontally moving the box-shaped sleeve frame 16 left and right, the drilling of the connecting bolt holes is realized.

[0023] The horizontal beam sleeve of the box-shaped sleeve frame 16 is movably sleeved on the horizontal beam steel bars of the box-shaped steel bar frame 4. A steel pipe is movably passed through each of the four horizontal beam steel bars of the box-shaped steel bar frame 4. A base plate is connected between the two steel pipes below, and a top plate is connected between the two steel pipes above. Then, the base plate and the top plate are fixedly connected together through connecting columns, thereby constructing an integral box-shaped sleeve frame 16. The box-shaped sleeve frame 16 can move left and right along the horizontal beam of the box-shaped steel bar frame 4; The electric drill 17 is fixed between the base plate and the top plate, so that moving the box-shaped sleeve frame 16 is equivalent to moving the electric drill 17 left and right.

[0024] A rack penetration frame column 9 is fixedly connected to the lower longitudinal frame of the U-shaped frame at the left end of the box-shaped frame 4. A rack penetration frame 10 is connected to the top of the rack penetration frame column 9. The rack penetration frame 10 plays a role in guiding and supporting the rack 19. A horizontally arranged rack 19 is movably arranged in the rack penetration frame 10. The right end of the rack 19 is fixedly connected to the left end of the electric drill 17. The electric drill 17 is pushed to move to the right by the movement of the rack 19 to realize the drilling of the bolt connection hole. A gear central axis support cantilever frame 11 is fixedly connected to the rack penetration frame 10. Gear central axis support bearings 12 are arranged at the two outer ends of the gear central axis support cantilever frame 11. The central axis of the gear 13 is arranged in a pair of gear central axis support bearings 12. The gear 13 is arranged above the rack 19 through the gear central axis support cantilever frame 11 and meshes with the rack 19. A pin shaft 20 is arranged on the outer shell of a pair of gear central axis support bearings 12. A swing arm rod 14 is movably connected to the pin shaft 20. A gear pushing claw 15 is connected to the swing arm rod 14. The gear pushing claw 15 is in movable abutting fit with the teeth on the gear 13. The lower U-shaped frame of the swing arm rod 14 is movably sleeved on a pair of pin shafts 20. The swing arm rod 14 can swing around a pair of pin shafts. The central axis of a pair of pin shafts 20 and the central axis of a pair of gear central axis support bearings 12 are in an eccentric setting state. When the swing arm rod 14 swings counterclockwise, the gear pushing claw 15 on it abuts against the left side teeth of the gear 13. When the swing arm rod 14 swings clockwise, the gear pushing claw 15 on it disengages from the gear 13. Thus, through the swing of the swing arm rod 14, a step-by-step movement and drilling of the electric drill 17 to the right are realized.

[0025] A method for drilling bolt connection holes between a photovoltaic support column and a screw pile barrel, characterized by comprising the following steps:

[0026] First step: Hook the triangular frame-shaped cantilever bracket 7 on the right side of the box-shaped steel bar frame 4 to the screw pipe pile barrel 1 above the ground, and clamp the lower arc-shaped holding plate 6 and the upper arc-shaped holding plate 8 on the screw pipe pile barrel 1, so that the box-shaped steel bar frame 4 is horizontally suspended on the screw pipe pile barrel 1. Adjust the height of the box-shaped steel bar frame 4 to make the drill bit 18 of the electric drill 17 align with a pair of bolt penetration holes 3. The box-shaped steel bar frame 4 is suspended on the screw pipe pile barrel 1 above the ground, constructing a horizontal movement platform for the electric drill 17, which not only ensures the drilling quality but also facilitates the drilling operation of on-site personnel.

[0027] Step 2: Connect the power supply of the electric drill 17, swing the swing arm rod 14 counterclockwise. The gear push claw 15 connected to the swing arm rod 14 abuts against the teeth of the gear 13, causing the gear 13 to rotate counterclockwise. The gear 13 meshes with the rack 19 to push the rack 19 to move to the right. The rack 19 drives the electric drill 17 to move to the right, so that the drill bit 18 enters the bolt through-hole 3, and drills the photovoltaic support column 2 inserted in the spiral pipe pile cylinder 1; the swing arm rod 14 provides a horizontal driving force for the electric drill to drill through the rotation push of the gear 13 by the gear push claw 15.

[0028] Step 3: Swing the swing arm rod 14 clockwise. The gear push claw 15 connected to the swing arm rod 14 disengages from the teeth on the gear 13. At this time, the movement of the rack 19 and the electric drill 17 to the right stops; the reciprocating swing of the swing arm rod 14 realizes the step-by-step rightward movement of the electric drill.

[0029] Step 4: Swing the swing arm rod 14 counterclockwise again. The gear push claw 15 connected to the swing arm rod 14 abuts against the teeth of the gear 13 again, causing the gear 13 to rotate counterclockwise. The gear 13 meshes with the rack 19 to push the rack 19 to move to the right again, realizing the further rightward movement and drilling of the drill bit 18.

[0030] Step 5: Repeat the steps of Step 2 to Step 5 until the top of the drill bit 18 emerges from the right hole of a pair of bolt through-holes 3, and then turn off the power supply of the electric drill 17, thus completing the drilling of the bolt through-holes on the photovoltaic support column 2.

[0031] Step 6: Swing the swing arm rod 14 clockwise to disengage the gear push claw 15 connected to the swing arm rod 14 from the teeth on the gear 13; move the box-shaped sleeve frame 16 to the left. The gear 13 rotates clockwise, so that the drill bit 18 completely withdraws from the drilled bolt through-hole; remove the box-shaped steel bar frame 4 from the spiral pipe pile cylinder 1.
