Description

Technical Field

[0001] This utility model belongs to the field of pile foundation construction technology, and specifically relates to a pile foundation construction hole positioning device. Background Technology

[0002] Before pile foundation construction, it is necessary to mark the drilling points. In the existing technology, a marking vehicle is usually used to mark the points with colored powder so that drilling can be carried out with the marked points as the center during subsequent drilling operations.

[0003] A related patent (publication number CN220716551U) discloses a pile foundation hole marking device for pile foundation construction. The device includes a base plate with multiple casters mounted on its underside and a clearance groove on its upper side. Two upright plates are fixedly connected to the upper side of the base plate, and a guide rod is fixedly connected between the two upright plates. A first slider and a second slider are slidably connected to the guide rod. The first slider is equipped with a powder spraying device, and the second slider is equipped with a protective cover pressing device. After marking the pile foundation hole, the device can quickly move to the designated position and deploy the protective cover, completely covering the mark. This effectively prevents construction personnel from accidentally touching and damaging the pile foundation hole mark.

[0004] However, after the above scheme marks the location of the pile foundation construction holes, when drilling, the center point of the mark point is still difficult to locate accurately because the mark point has a certain area. When drilling, the center point of the mark point can often only be judged by the experience of the drilling personnel, which makes it impossible to achieve precise drilling operations. In addition, the powder used for marking often sticks to the inner wall of the material bucket due to static electricity, and cannot fall completely, affecting the integrity of the mark. Utility Model Content

[0005] To address the problems in existing technologies, such as the difficulty in accurately locating the center point of a marker point due to its area, which often necessitates relying on the experience of drilling personnel to determine the center point during drilling, thus hindering precise drilling operations, this invention provides a pile foundation drilling location positioning device. This device alternates between a center point marker and a ring-shaped marker. The center point provides precise identification of the drilling center, while the ring-shaped marker allows workers to quickly locate the center point, thereby enabling precise drilling operations and improving pile foundation drilling accuracy. The specific technical solution is as follows:

[0006] A pile foundation construction hole positioning device includes a feed inlet, the bottom end of which is connected to a connecting cylinder, and the bottom end of the connecting cylinder is connected to an outer feeding cylinder. The outer feeding cylinder is configured as a funnel shape, narrower at the top and wider at the bottom. A connecting rod is fixedly installed at the bottom end of the inner wall of the outer feeding cylinder, and a baffle cylinder is fixedly installed on the connecting rod. The baffle cylinder and the outer feeding cylinder form an annular space for powder to fall. A central feeding cylinder is arranged vertically in the inner cavity of the baffle cylinder. The central feeding cylinder is a hollow cylindrical body, and a vertical space for powder to fall is provided in the middle of the central feeding cylinder. The upper surface of the central feeding cylinder and the upper surface of the baffle cylinder are located on the same horizontal line.

[0007] In the above technical solution, an installation seat is fixedly installed on the inner side wall of the baffle cylinder, and an installation groove is opened on the lower surface of the installation seat. An installation rod is fixedly installed at the bottom end of the side wall of the central feed cylinder. The installation rod is embedded in the inner cavity of the installation groove. A positioning pin is threadedly embedded in the outer wall of the installation rod, and the end of the positioning pin is threadedly embedded in the inner wall of the installation groove.

[0008] In the above technical solution, support arms are respectively installed on the front and rear side walls of the connecting cylinder. A fixed rod is provided through the outer wall of the support arm in a horizontal direction, and the fixed rod is fixedly connected to the support arm. Moving seats are symmetrically slidably sleeved on the left and right sides of the outer wall of the fixed rod. A moving plate is fixedly connected to the outer wall of the moving seat. A spring is sleeved on the outer wall of the fixed rod, and the two ends of the spring are respectively connected to the outer wall of the fixed rod and the outer wall of the moving plate. A striking seat is fixedly installed on the outer wall of the moving plate, and the striking seat intermittently strikes the outer wall of the connecting cylinder.

[0009] In the above technical solution, a support plate is fixedly installed on the outer wall of the front support arm. Two rotating shafts are rotatably connected to the front side wall of the support plate. Cams and gears are fixedly installed on the outer walls of the two rotating shafts respectively. The two cams are symmetrically arranged on the left and right. The outer walls of the cams rotate and fit against the side wall of the movable seat. The outer walls of the two gears are meshed and connected.

[0010] In the above technical solution, one of the output ends of the rotating shaft is connected to a motor.

[0011] In the above technical solution, the striking seat is set to be arc-shaped, and the arc of the striking seat is adapted to the arc of the side wall of the connecting cylinder.

[0012] In the above technical solution, a connecting arm is fixedly installed on the side wall of the outer feed cylinder, a support frame is fixedly installed on the outer wall of the connecting arm, and the motor is mounted on the upper surface of the support frame through a motor frame.

[0013] In the above technical solution, columns are vertically installed at the four corners of the bottom of the support frame, and casters are installed at the bottom of the columns.

[0014] In the above technical solution, the outer wall of the support frame is provided with a traction hole.

[0015] The present invention provides a pile foundation construction borehole positioning device, which, compared with the prior art, has the following advantages:

[0016] I. Given that existing marker points cover a certain area, their center point remains difficult to pinpoint accurately. During subsequent drilling, the center point often relies on the experience of the drilling personnel, hindering precise drilling operations. This invention addresses this issue by using a combination of a baffle cylinder, a central discharge cylinder, and an outer discharge cylinder to create an alternating effect between the center point marker and the ring-shaped marker. Compared to traditional large-area markers that struggle to determine the exact center, this invention's center point provides precise identification of the drilling center point. The ring-shaped marker allows workers to quickly locate the point, enabling precise drilling operations and improving the accuracy of pile foundation drilling.

[0017] II. This utility model, through the setting of a central feeding cylinder, mounting base, mounting groove, and mounting rod, enables the central feeding cylinder to be flexibly disassembled so that it can be replaced with different inner diameters as needed to adapt to the marking requirements of different diameter center points.

[0018] Third, to address the problem that the powder used for marking often sticks to the inner wall of the material barrel due to static electricity, preventing it from falling completely and affecting the integrity of the fixed-point marking, this utility model uses a motor, gears, shaft, cam, and spring to cause the moving seat, moving plate, and striking seat to intermittently strike the outer wall of the connecting cylinder, causing the feed inlet, connecting cylinder, and outer feed cylinder to vibrate as a whole, causing the powder to fall completely under the action of vibration, further ensuring the integrity of the fixed-point marking;

[0019] In summary, this utility model can achieve the effect of alternating center point markings and ring markings. The center point serves to precisely mark the center point of the hole, while the ring markings allow workers to quickly locate the fixed point, thereby achieving precise drilling operations and improving the drilling accuracy of pile foundations. In addition, by intermittently tapping and vibrating the connecting cylinder, the powder is made to fall completely, further ensuring the integrity of the fixed point markings.

Detailed Implementation

[0026] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0027] To address the existing technology's limitations, since the marked points have a certain area after formation, it is still difficult to accurately locate their center point. During subsequent drilling, the center point often relies on the driller's experience to determine its location, hindering precise drilling operations. Furthermore, the marking powder often adheres to the inner wall of the hopper due to static electricity, preventing it from falling completely and affecting the integrity of the markings. (See [reference needed]). Figures 1 to 5 As shown, a pile foundation construction hole positioning device includes an inlet 1 through which marking paint is poured downward to form marking points. The bottom end of the inlet 1 is connected to a connecting cylinder 2, and the bottom end of the connecting cylinder 2 is connected to an outer feeding cylinder 3. The outer feeding cylinder 3 is funnel-shaped, narrow at the top and wide at the bottom. A connecting rod 4 is fixedly installed at the bottom of the inner wall of the outer feeding cylinder 3, and a baffle cylinder 5 is fixedly installed on the connecting rod 4. The connecting rod 4 causes the baffle cylinder 5 and the outer feeding cylinder 3 to be fixedly connected, forming an annular space for powder to fall. The space causes the powder to form a ring-shaped mark, so that the staff can quickly find the location of the fixed point. The inner cavity of the baffle cylinder 5 is provided with a central feeding cylinder 6 in the vertical direction. The central feeding cylinder 6 is a hollow cylindrical body. The central feeding cylinder 6 has a vertical space in the middle for the powder to fall. The powder falling through the inner cavity of the central feeding cylinder 6 forms a small diameter dot, so as to accurately locate the center point of the hole. Moreover, the upper surface of the central feeding cylinder 6 and the upper surface of the baffle cylinder 5 are on the same horizontal line, avoiding the problem of powder accumulation due to the height difference between the upper surfaces of the central feeding cylinder 6 and the upper surfaces of the baffle cylinder 5.

[0028] When determining the location of the drilling hole during pile foundation construction, powder is placed into the inner cavity of the feed inlet 1. The powder falls through the inner cavity of the central feed cylinder 6 and the annular space formed by the baffle cylinder 5 and the outer feed cylinder 3. The powder falling through the inner cavity of the central feed cylinder 6 forms a small-diameter dot, which is used to accurately locate the center point of the hole. The powder falling through the annular space formed by the baffle cylinder 5 and the outer feed cylinder 3 forms an annular mark outside the center point of the central feed cylinder 6, so that the workers can quickly find the location of the drilling point. By aligning the drilling device with the center point of the central feed cylinder 6, precise drilling can be achieved.

[0029] See Figure 3 and Figure 4 As shown, a mounting base 7 is fixedly installed on the inner wall of the baffle cylinder 5. A mounting groove 8 is opened on the lower surface of the mounting base 7. A mounting rod 9 is fixedly installed at the bottom of the side wall of the central feed cylinder 6. The mounting rod 9 is embedded in the inner cavity of the mounting groove 8. A positioning pin 10 is threadedly embedded in the outer wall of the mounting rod 9, and the end of the positioning pin 10 is threadedly embedded in the inner wall of the mounting groove 8. If it is necessary to adjust the diameter of the center point formed at the central feed cylinder 6 according to different operating environments, the positioning pin 10 is unscrewed from the outer wall of the mounting rod 9 and the mounting groove 8, the central feed cylinder 6 is removed from the baffle cylinder 5, a central feed cylinder 6 with a suitable inner diameter is replaced, the mounting rod 9 is re-embedded into the inner cavity of the mounting groove 8, and the positioning pin 10 is screwed into the inner cavity of the mounting rod 9 and the mounting groove 8 to position the mounting rod 9 in the inner cavity of the mounting groove 8, so as to realize the connection between the central feed cylinder 6 and the baffle cylinder 5.

[0030] See Figure 1 and Figure 5 As shown, support arms 11 are installed on the front and rear side walls of the connecting cylinder 2, respectively. A fixed rod 12 is installed through the outer wall of the support arm 11 in the horizontal direction, and the fixed rod 12 is fixedly connected to the support arm 11. Moving seats 13 are symmetrically slidably sleeved on the left and right sides of the outer wall of the fixed rod 12. A moving plate 14 is fixedly connected to the outer wall of the moving seat 13. A spring 15 is sleeved on the outer wall of the fixed rod 12, and the two ends of the spring 15 are respectively connected to the outer wall of the fixed rod 12 and the outer wall of the moving plate 14. A striking seat 16 is fixedly installed on the outer wall of the moving plate 14. The striking seat 16 intermittently strikes the outer wall of the connecting cylinder 2. When the moving seat 13 is subjected to force and moves along the outer wall of the fixed rod 12, it causes the moving plate 14 and the striking seat 16 to move synchronously, thereby causing the striking seat 16 to intermittently strike and vibrate the outer wall of the connecting cylinder 2 to assist in the complete discharge of powder.

[0031] For details, please refer to [link / reference]. Figure 5As shown, a support plate 17 is fixedly installed on the outer wall of the front support arm 11. Two rotating shafts 18 are rotatably connected to the front side wall of the support plate 17 via bearings. Cams 19 and gears 20 are fixedly installed on the outer walls of the two rotating shafts 18 respectively. The two cams 19 are symmetrically arranged on the left and right sides. The outer walls of the cams 19 rotate and fit against the side wall of the movable seat 13. The outer walls of the two gears 20 mesh and connect. The cams 19 on the left and right sides can synchronously drive the movable seats 13 at corresponding positions on the left and right sides to move. A motor 21 is connected to the output end of one of the rotating shafts 18. In this embodiment, the motor 21 is connected to the right rotating shaft 18.

[0032] The motor 21, when turned on, causes the right-side shaft 18 to rotate, which in turn drives the cam 19 and gear 20 on the outer wall of the right-side shaft 18 to rotate. Since the outer walls of the two gears 20 are meshed, the left-side gear 20 rotates in the opposite direction to the right-side gear 20, so that the cams 19 on both sides rotate counterclockwise synchronously. When the distal side of the cam 19 rotates to fit against the side wall of the moving seat 13, it drives the moving seat 13 to move the moving plate 14 and the striking seat 16 outward, and forces the spring 15 to compress. When the proximal side of the cam 19 rotates to fit against the side wall of the moving seat 13, the spring force of the spring 15 causes the moving seat 13, the moving plate 14, and the striking seat 16 to move inward synchronously, so that the striking seat 16 strikes the side wall of the connecting cylinder 2. With the circumferential rotation of the cam 19 and the spring force of the spring 15, the striking seat 16 intermittently strikes the side wall of the connecting cylinder 2, so as to cause the whole equipment to vibrate, which helps to make the powder fall completely and avoids the powder being electrostatically adsorbed on the inner wall of the equipment.

[0033] Specifically, the striking seat 16 is set in an arc shape, and the arc of the striking seat 16 is adapted to the arc of the side wall of the connecting cylinder 2, so as to ensure that when the striking seat 16 strikes the side wall of the connecting seat 2, the outer wall of the striking seat 16 can completely fit the side wall of the connecting seat 2, thereby increasing the contact area of ​​the striking and causing the connecting seat 2 and the whole equipment to vibrate more completely.

[0034] See Figure 1 and Figure 5 As shown, a connecting arm 23 is fixedly installed on the side wall of the outer feed cylinder 3, and a support frame 22 is fixedly installed on the outer wall of the connecting arm 23. The motor 21 is mounted on the upper surface of the support frame 22 through the motor frame. The connecting arm 23 forms a stable connection between the support frame 22 and the outer feed cylinder 3, and the support frame 22 provides support for the installation of the motor 21. Columns 24 are vertically installed at the four corners of the bottom of the support frame 22, and casters 25 are installed at the bottom of the columns 24. The casters 25 can facilitate the overall movement of the equipment to a suitable construction position, making it easier to transport the equipment. Of course, in order to facilitate the horizontal movement of the equipment, a traction hole 26 is opened on the outer wall of the support frame 22. A traction device can be hooked onto the traction hole 26 to move the equipment horizontally.

[0035] The working principle of the pile foundation construction borehole positioning device in this embodiment is as follows:

[0036] When determining the location of the drilling hole during pile foundation construction, powder is placed into the inner cavity of the feed inlet 1. The powder falls through the inner cavity of the central feed cylinder 6 and the annular space formed by the baffle cylinder 5 and the outer feed cylinder 3. The powder falling through the inner cavity of the central feed cylinder 6 forms a small-diameter dot, which is used to accurately locate the center point of the hole. The powder falling through the annular space formed by the baffle cylinder 5 and the outer feed cylinder 3 forms an annular mark outside the center point of the central feed cylinder 6, so that the workers can quickly find the location of the drilling point. By aligning the drilling device with the center point of the central feed cylinder 6, precise drilling can be achieved.

[0037] If the diameter of the center point formed at the center discharge cylinder 6 needs to be adjusted according to different operating environments, the positioning pin 10 is unscrewed from the outer wall of the mounting rod 9 and the mounting groove 8, the center discharge cylinder 6 is removed from the baffle cylinder 5, a center discharge cylinder 6 with a suitable inner diameter is replaced, the mounting rod 9 is re-embedded into the inner cavity of the mounting groove 8, and the positioning pin 10 is screwed into the inner cavity of the mounting rod 9 and the mounting groove 8 to position the mounting rod 9 in the inner cavity of the mounting groove 8, so as to realize the connection between the center discharge cylinder 6 and the baffle cylinder 5;

[0038] The motor 21, when turned on, causes the right-side shaft 18 to rotate, which in turn drives the cam 19 and gear 20 on the outer wall of the right-side shaft 18 to rotate. Since the outer walls of the two gears 20 are meshed, the left-side gear 20 rotates in the opposite direction to the right-side gear 20, so that the cams 19 on both sides rotate counterclockwise synchronously. When the distal side of the cam 19 rotates to fit against the side wall of the moving seat 13, it drives the moving seat 13 to move the moving plate 14 and the striking seat 16 outward, and forces the spring 15 to compress. When the proximal side of the cam 19 rotates to fit against the side wall of the moving seat 13, the spring force of the spring 15 causes the moving seat 13, the moving plate 14, and the striking seat 16 to move inward synchronously, so that the striking seat 16 strikes the side wall of the connecting cylinder 2. With the circumferential rotation of the cam 19 and the spring force of the spring 15, the striking seat 16 intermittently strikes the side wall of the connecting cylinder 2, so as to cause the whole equipment to vibrate, which helps to make the powder fall completely and avoids the powder being electrostatically adsorbed on the inner wall of the equipment.

[0039] This invention achieves the effect of alternating center point markings and ring markings. The center point serves to precisely identify the center point of the hole, while the ring markings allow workers to quickly locate the fixed point, thereby enabling precise drilling operations and improving the accuracy of pile foundation drilling. In addition, by intermittently tapping and vibrating the connecting cylinder 2, the powder is made to fall completely, further ensuring the integrity of the fixed point markings.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
