Description

Technical Field

[0001] This utility model belongs to the field of verticality detection technology for driven piles and pipelines, specifically a device for detecting the verticality of driven piles. Background Technology

[0002] Pile driving is a construction process that uses a superstructure load to press a pile into the ground. The construction methods for pile driving all involve driving various prefabricated piles, primarily reinforced concrete, prestressed concrete solid piles, or pipe piles, but also steel or wooden piles, into the foundation to the required depth using different driving methods. The verticality of the pile relative to the horizontal plane is one of the important inspection standards for pile driving projects.

[0003] Meanwhile, patent application number 202020531485.8 discloses a pile verticality detection device, including a cylinder covering the side of the pile body, an upper plate at the top of the cylinder body, a pull line connected to the upper plate body, an upper end of the pull line connected to the plate body, and a plumb bob connected to the lower end of the pull line. The cylinder covers the side of the pile body, and the plumb bob hangs down under gravity and straightens the pull line. The verticality of the pile body can be detected by the angle between the pull line and the pile body. However, during the implementation of the relevant technology, it was found that the aforementioned pile verticality testing device has several drawbacks. It uses a plumb bob to test verticality, is only suitable for relatively low pile pipes, and requires testing personnel to observe nearby, which poses a high risk factor. Furthermore, the results are not accurate enough when measuring at higher positions by visually observing the scale position of the plumb bob. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a pile driving verticality detection device, which has the advantages of reducing manual intervention, using a more advanced laser generator in conjunction with a receiver for detection, being designed for use in harsh environments, and improving dust removal and obstruction control.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pile driving verticality detection device, comprising a pile driving pipe, wherein two sets of collars are bolted to the surface of the pile driving pipe, a dustproof area is provided between the inner sides of the collars, and a verticality detection device is provided inside the dustproof area of ​​the collars. Two sets of limiting frames in opposite directions are fixedly connected to the bottom end of the collar. The surfaces of the two sets of limiting frames are respectively provided with arc grooves. An extension seat is rotatably mounted inside the arc grooves of the two sets of limiting frames. A connecting seat is fixedly connected to the end of the extension seat away from the limiting frame. The extension seat can rotate in the sliding groove of the limiting frame. A transparent corrugated tube is fixedly connected to the bottom end of the connecting seat. The transparent corrugated tube is used to cover the verticality detection device in the dustproof area of ​​the collar. The perpendicularity detection device of the collar includes a laser emitter and a laser receiver. The laser receiver and the laser emitter are arranged in a perpendicular opposing configuration. The range of motion of the laser emitter and the laser receiver is limited to the offset area. A scale is fixedly fitted on the surface of the laser receiver. The laser receiver is threaded to the inner wall of the bottom end of the collar through an anti-loosening threaded rod.

[0006] Preferably, one end of the lifting ring is fixedly connected to the inner wall of the top of the collar, and one end of the connecting rope is fixedly connected to the other end of the lifting ring. The other end of the connecting rope is fixedly connected to a laser emitter.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a pile driving verticality detection device, including a pile driving pipe 1. Two sets of collars 2 are bolted to the surface of the pile driving pipe 1. A dustproof area is set between the inner sides of the collars 2. A verticality detection device is set inside the dustproof area of ​​the collars 2. Two sets of limiting frames 72 in opposite directions are fixedly connected to the bottom end of the collar 2. The surfaces of the two sets of limiting frames 72 are respectively provided with arc grooves. An extension seat 71 is rotatably mounted inside the arc grooves of the two sets of limiting frames 72. A connecting seat 7 is fixedly connected to the end of the extension seat 71 away from the limiting frame 72. The extension seat 71 rotates in the sliding groove of the limiting frame 72. A transparent corrugated tube 73 is fixedly connected to the bottom end of the connecting seat 7. The transparent corrugated tube 73 is used to cover the verticality detection device in the dustproof area of ​​the collar 2. The verticality detection device of the collar 2 includes a laser emitter 23 and a laser receiver 26. The laser receiver 26 and the laser emitter 23 are arranged in a vertically opposite position. The range of motion of the laser emitter 23 and the laser receiver 26 is limited to the offset area 4. A scale 27 is fixedly embedded on the surface of the laser receiver 26. Under normal circumstances, when the pile is in a vertical state, the laser emitter 23 emits a laser beam and the laser beam falls on the center position of the surface of the laser receiver 26. When the laser beam falls to the previous position of the center position of the laser receiver 26, it indicates that the pile driving device has deviated. The current position of the deviation is recorded by the scale 27, and the pile driving device is adjusted to ensure that the laser beam can fall vertically on the center position of the laser receiver 26. The laser receiver 26 is fixed to the anti-loosening threaded rod 28 and threadedly connected to the inner wall of the bottom end of the collar 2 to prevent the laser receiver 26 from deviating due to vibration.

[0018] Specifically, a lifting ring 21 is fixedly connected to the inner wall of the top of the collar 2. The lifting ring 21 is fixed to the laser emitter 23 by a connecting rope 22. The movable connecting rope 22 facilitates the hoisting of the laser emitter 23 and the adjustment of its corresponding position. An air inlet 24 is provided on the surface of the laser emitter 23. A removable filter cotton 25 is installed inside the air inlet 24 to filter the air entering the laser emitter 23, reducing dust from entering the laser emitter 23 and causing damage to the laser emitter 23 and the area around the lens 29.

[0019] Furthermore, the bottom of the laser emitter 23 is integrally formed with a lens 29, and an air outlet area 6 is provided around the lens 29.

[0020] Furthermore, two sets of miniature centrifugal fans 8 are fixedly connected to the surface of the collar 2. The miniature centrifugal fans 8 are positioned away from the surface of the collar 2, and the air blown by the miniature centrifugal fans 8 forms a blowing area 81. Please refer to the attached document. Figure 2 Two sets of miniature centrifugal fans 8 are equidistantly arranged on the surface of the collar 2 and are inclined to the transparent corrugated tube 73. The miniature centrifugal fans 8 blow away the dust attached to the surface of the transparent corrugated tube 73, preventing dust from accumulating on the surface of the transparent corrugated tube 73. The internal situation of the transparent corrugated tube 73 cannot be seen from the outside. The airflow covers the entire surface of the transparent corrugated tube 73, avoiding blowing directly at the lens 29, and keeping the surface of the transparent corrugated tube 73 clean.

[0021] It is worth noting that the transparent corrugated tube 73 covers the relevant parts of the verticality detection device of the collar 2, preventing dust from falling or adhering to the surface of the protective cover. The transparent corrugated tube 73 deforms between the upper and lower inner walls of the collar 2, making it easy to open and close.

[0022] It is worth noting that the air inlet 24 is located in the leeward area 5 of the collar 2, the air inlet of the collar 2 is set in a spiral shape, and the air outlet area 6 set on the surface of the lens 29 is arrayed around the lens 29 to prevent the airflow from blowing directly into the core area of ​​the vertical area 3. Due to the uneven airflow density, the laser refraction error is caused, and the airflow forms a barrier along the outer side of the laser path.

[0023] It is worth mentioning that the air pressure inside the laser emitter 23 is greater than the air pressure outside, and the direction of the wind is the same as or opposite to the direction of the vertical area 3, which can reduce the amount of airborne dust passing through the laser path.

[0024] The laser emitter 23 and laser receiver 26 are existing technologies and will not be described in detail. Additionally, this invention also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0025] Working principle: Two sets of collars 2 are respectively fitted onto the surface of the pile driving pipe 1, and the two sets of collars 2 are fixed to the surface of the pile driving pipe 1 with bolts. The pile driving machine lifts the pile driving pipe 1 into the air and keeps it static for a period of time to reduce the shaking of the pile driving pipe 1 at the bottom of the pile driving machine. When the pile driving pipe 1 shakes to a degree that cannot be observed by the naked eye, the laser emitter 23 is activated to emit laser light onto the surface of the laser receiver 26, and the transparent corrugated tube 73 is pulled toward the inner wall of the bottom end of the collar 2. The transparent corrugated tube 73 is used to cover the laser emitter 23 and the bottom lens 29. The laser emitter 23 emits a laser signal toward the surface of the laser receiver 26. Since the pile driving pipe 1 is not completely stationary, the signal emitted by the laser emitter 23 is directed toward the scale 27 on the surface of the laser receiver 26, which is the offset area 4 in the figure. When the laser beam shifts from the offset area 4 to the vertical area 3, the current value is determined based on the laser feedback. When construction is carried out under good visibility conditions, the transparent corrugated pipe 73 can be removed, and the extension seat 71 can be slid out from the arc groove of the extension seat 72 by rotating the connecting seat 7. The laser emitter 23 has a negative pressure device inside, which keeps the interior under negative pressure. External air is drawn in through the air inlet 24 on the surface of the laser emitter 23. During the intake process, the external air is filtered by the filter cotton 25 and discharged through the annular exhaust groove of the lens 29. The discharged air protects the lens 29 and prevents interference with the stability of the laser beam when the signal emitted from the laser emitter 23 shines on the laser receiver 26. For external cleaning of the transparent corrugated pipe 73, a miniature centrifugal fan 8 is used to blow on the transparent corrugated pipe 73 to prevent dust from falling or covering the transparent corrugated pipe 73 and obstructing viewing from the outside of the transparent corrugated pipe 73 to the inside.
