Description

Technical Field

[0001] The invention belongs to the technical field of bored cast-in-place pile hole detection, and in particular relates to an intelligent scanning device for bored cast-in-place pile hole size abnormalities. Background Art

[0002] Currently, during construction, a hole must be drilled into the building site, followed by the placement of a steel cage and the pouring of concrete. Before concrete pile construction, a borehole inspection device is required to check the diameter and verticality of the bored pile. This allows for accurate internal conditions and, accordingly, to be tailored to facilitate the placement of the steel cage and the pouring of concrete. The conventional process involves welding a cage-like structure whose dimensions match the diameter of the pile hole to be inspected, with a pointed conical end. A crane is used to lift the cage's pointed conical end, maintaining its vertical position, and gradually lowering it into the pile hole. If the cage deflects or encounters resistance, this indicates a change in the diameter or verticality of the pile hole, thereby achieving pile hole inspection. However, for pile hole diameters of varying sizes, multiple steel cage borehole inspection devices must be manufactured for inspection, wasting material and occupying storage space. Furthermore, after pile construction is completed, the borehole inspection device is bulky and inconvenient to transfer to the next project. Summary of the Invention

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0036] The present invention discloses an intelligent scanning device for abnormal bored pile hole size. Figure 1-16As shown, it includes an all-terrain hanger 100, a rope retracting and releasing mechanism 200, a guide wheel type inclination detection mechanism 500 and a pendant type detection mechanism 400. Among them, the all-terrain hanger 100 is fixed at the upper end of the pile hole, and the rope retraction mechanism 200 includes a mounting seat 201, an articulated connector and a winch 205. The all-terrain hanger 100 is connected to the mounting seat 201 through an articulated connector. The winch 205 and the guide wheel inclination detection mechanism 500 are both installed on the mounting seat 201. The guide wheel inclination detection mechanism 500 is movably connected to the mounting seat 201, and the rope 300 is reeled on the winch 205. One end of the rope 300 passes through the guide wheel inclination detection mechanism 500 and is connected to the pendant detection mechanism 400. The pendant detection mechanism 400 has a dual-axis inclination sensor and multiple ultrasonic sensors, and the all-terrain hanger 100 is connected to a casing 700, which is supported on the inner wall of the top of the pile hole. The working principle and advantages of the present invention are as follows: the present invention fixes the entire device above the pile hole through the all-terrain hanger 100. Since the all-terrain hanger 100 has all-terrain adaptability, it can achieve the purpose of stable fixation under various terrain conditions; the articulated connector of the present invention is used to connect the mounting seat 201 and the all-terrain hanger 100, that is, when the all-terrain hanger 100 is in a non-horizontal state after installation, the mounting seat 201 is kept in a horizontal state through the articulated connector, so that the winch 205 installed on the mounting seat 201 is kept in a horizontal state, so that the lifting rope 300 is kept in a vertical downward state during the release process, which is convenient for the problem of detection error caused by the release of the lifting rope 300; when the pendant detection mechanism 400 is applied to the pile hole and gradually applied downward, the dual-axis inclination sensor on the pendant detection mechanism 400 detects the inclination of the lifting rope 300, and the ultrasonic sensor detects the inclination of the lifting rope 300. The sensor is used to scan the circumference of the pile hole; since during the lowering process, in addition to the displacement of the pendant detection mechanism 400, the pendant detection mechanism 400 is affected by the water, air, etc. in the pile hole, the more the pendant detection mechanism 400 is lowered, the greater the frequency and amplitude of its swing. Therefore, the guide wheel inclination detection mechanism 500 detects the inclination of the suspension rope 300. When the lowering depth is obtained, the inclination value of the suspension rope 300 can also be obtained. The inclination value measured by the dual-axis inclination sensor of the pendant detection mechanism 400 can be used to analyze the inclination value of the pile hole in different directions. The above two inclination values are used to make a correction (verticality correction), so that the inclination of the detection end of the pendant detection mechanism 400 and the suspension rope 300 is eliminated; since at the beginning of the lowering, the suspension rope 300 coincides with the center line of the pile hole at the hole mouth, when the suspension rope 300 tilts, the hole diameter change and the inclination of the pile hole can be detected.The present invention includes multiple ultrasonic sensors, one of which is installed at the lower end of the pendant-type detection mechanism 400 to detect the hole depth and confirm the distance from the bottom of the hole, so as to avoid damage to the pendant-type detection mechanism 400 due to hard contact with the bottom of the hole; the other ultrasonic sensors are evenly installed around the pendant-type detection mechanism 400 to detect the hole wall; in summary, the present invention can adapt to the detection of different types of pile holes in different terrains, and can detect the pile hole diameter and verticality extremely accurately, which is convenient for disassembly and transportation, and avoids waste of materials.

[0037] As a preferred embodiment of the present invention, Figure 2 、 10 As shown, the all-terrain hanger 100 includes a fixed base 101 and a plurality of adjustable anchoring units 600. The lower end of the fixed base 101 is detachably connected to an articulated connector. The fixed base 101 is a disc-shaped structure and is fixedly connected to an assembly ring 105 via a plurality of connecting rods 104. The axis of the assembly ring 105 coincides with the axis of the fixed base 101, and the connecting rods 104 are evenly arranged along the circumference of the fixed base 101. The plurality of adjustable anchoring units 600 described in this embodiment are installed on the assembly ring 105 at intervals along the circumference of the assembly ring 105. The adjustable anchoring units 600 of this embodiment include an angle adjustment base and an anchoring rod, and the anchoring rod is connected to the angle adjustment base. The working principle and advantages of this embodiment are: this embodiment adjusts the connection position of the angle adjustment seat on the assembly ring 105, and the connection angle between the angle adjustment seat and the assembly ring 105, so that the anchor rod can be firmly anchored in the pile hole foundation 800 of the corresponding terrain, and then in subsequent inspection operations, the all-terrain hanger 100 will not be displaced, tilted or tipped over, thereby avoiding inaccurate inspection results or safety accidents.

[0038] As a preferred embodiment of the present invention, Figure 10-14As shown, the angle adjustment seat includes a seat body 601 and an adjustment block 602. The seat body 601 is constructed with two connecting ears 605. These two connecting ears 605 are arranged opposite each other and clamped on the assembly ring 105. The two connecting ears 605 are connected by a fixing bolt, thereby locking the seat body 601 to the assembly ring 105. The adjustment block 602 of this embodiment is disposed at the end of the seat body 601 away from the assembly ring 105. The adjustment block 602 is rotatably connected to the seat body 601 via a connecting shaft 603. The connecting shaft 603 is arranged horizontally, and the axis of the connecting shaft 603 is perpendicular to the axis of the assembly ring 105. The adjustment block 602 is provided with a connecting hole 604, through which the anchor rod is connected to the adjustment block 602. The specific structure of the anchor rod of this embodiment is as follows: the anchor rod includes a rod-shaped body 606, a plug rod 610, and two rotary anchor claws 611. The rod-shaped body 606 is threaded with threads, which are threadedly connected to the connecting hole 604, thereby achieving a threaded connection between the rod-shaped body 606 and the adjustment block 602. In this embodiment, an assembly channel 608 is defined within the rod-shaped body 606. This assembly channel 608 extends along the axis of the rod-shaped body 606 and extends through both ends of the rod-shaped body 606. The insertion rod 610 is inserted into the rod-shaped body 606 through the assembly channel 608, and the two ends of the insertion rod 610 extend out of the two ends of the rod-shaped body 606. The two rotary anchor claws 611 described in this embodiment are disposed at the lower end of the insertion rod 610. One end of each rotary anchor claw 611 is hinged to the lower end of the insertion rod 610, and the other end of the rotary anchor claw 611 is hinged to the hinge arm 607. The hinge arm 607 is hinged to the lower end of the rod-shaped body 606 at one end away from the rotary anchor claw 611. In this embodiment, a threaded connector 609 is constructed at the upper end of the rod-shaped body 606, and the threaded connector 609 is threadedly connected to an adjustment cap 612. A connecting joint 614 is constructed on the lower surface of the upper end of the adjustment cap 612, and the connecting joint 614 is rotatably connected to the upper end of the plug-in rod 610, and an operating head 613 is constructed on the upper surface of the upper end of the adjustment cap 612.The working principle and advantages of this embodiment are as follows: when encountering an uneven pile hole foundation 800, adjust the angle between the adjustment block 602 and the assembly ring 105, and then rotate the adjusting cap 612 so that the adjusting cap 612 drives the plug-in rod 610 to move axially along the rod-shaped body 606, thereby achieving the purpose of adjusting the axial relative position between the plug-in rod 610 and the rod-shaped body 606, so that the two rotary digging type anchoring claws 611 are in a semi-open state, that is, at this time the function of the two rotary digging type anchoring claws 611 is the same as that of the drill bit; after the adjustment is completed, drive the rod-shaped body 606 to rotate, and the rod-shaped body 606 drives the rotary digging type anchoring claws 611 to rotate, and because the rod-shaped body 606 and the adjustment block 602 are threaded When the rod-shaped body 606 is connected, it gradually moves downward during the rotation of the rod-shaped body 606, so that the rotary drilling type anchor claw 611 drills the pile hole foundation 800, and the diameter of the hole drilled by the rotary drilling type anchor claw 611 is slightly larger than the radial length of the rod-shaped body 606, which facilitates the insertion of the rod-shaped body 606; when it is screwed into the predetermined depth, the driving of the rod-shaped body 606 is stopped, and then the adjusting cap 612 is rotated so that the adjusting cap 612 drives the plug-in rod 610 to move upward until the two rotary drilling type anchor claws 611 are fully opened. In this way, the purpose of anchoring the lower end of the anchor rod in the pile hole foundation 800 is achieved, so that the fixation of the entire all-terrain hanger 100 to the pile hole foundation 800 is extremely stable. When the anchor rod needs to be pulled out of the pile hole foundation 800, the adjusting cap 612 is rotated in the opposite direction to drive the plug rod 610 downward and drive the two rotary anchor claws 611 to close, thereby releasing the anchor rod from the pile hole foundation 800. In this way, the anchor rod can be pulled out by applying a certain external force to the anchor rod. Figure 2 As shown, all adjustable anchoring units 600 can be adjusted to a vertical position, so as to facilitate the downward excavation of the rotary anchoring claw 611. Figure 15 As shown, all the adjustable anchoring units 600 can be adjusted to an inclined shape, and the lower parts of these adjustable anchoring units 600 are in an outward-stretched shape, which improves the stability of the adjustable anchoring units 600 in supporting the entire scanning device, and the outward-stretched shape maintained by these anchoring rods that are inclined and inserted into the pile hole foundation 800 has greatly improved its anti-torsion ability, anti-external force collision ability and downward pressure ability; that is, when the anchoring rod is subjected to external force, it will decompose the external force into at least one of radial external force, axial external force and circumferential external force, and then transmit it to the nearby pile hole foundation 800 and other anchoring rods, so that the external force is mutually eliminated between the anchoring rods. When encountering a special-shaped pile hole foundation 800, and the local area of the special-shaped pile hole foundation 800 cannot be anchored by the anchoring rod, at this time, you should choose the following Figure 16The entire scanning device is fixed in the manner shown, that is, a part of the anchoring rods are concentrated in the area where the special-shaped pile hole foundation 800 can be fixed, and then these anchoring rods are anchored in the corresponding area, and then the other part of the anchoring rods (one or more anchoring rods) are removed from the assembly ring 105, and then anchored at a position outside the pile hole, and then the anchoring rods not connected to the assembly ring 105 are connected to the assembly ring 105 using the tensioning rope 900, and the assembly ring 105 is tensioned, and the tensioning position of the tensioning rope 900 is the part of the assembly ring 105 that is not supported by the anchoring rods, so that the overall force of the assembly ring 105 is balanced and stable, thereby ensuring that the all-terrain hanger 100 is firmly fixed on the pile hole foundation 800, avoiding tilting, rollover, etc.

[0039] As a preferred embodiment of the present invention, Figure 5-7 As shown, the articulated connector includes a connecting ball 103 and an annular ball sleeve 202. The upper end of the connecting ball 103 is configured with an adapter 102, which is detachably connected to the fixing seat 101 of the all-terrain hanger 100. The annular ball sleeve 202 is configured at the center of the upper end of the mounting seat 201, and the connecting ball 103 is movably assembled within the annular ball sleeve 202, allowing the connecting ball 103 to rotate within the annular ball sleeve 202. In this embodiment, a plurality of locking holes 203 are uniformly formed along the circumference of the annular ball sleeve 202. Each locking hole 203 is threadedly connected to a locking bolt. By tightening or loosening the locking bolt, the annular ball sleeve 202 and the connecting ball 103 are locked or unlocked. The working principle and advantage of this embodiment are: in order to ensure that the lifting rope 300 remains vertical when released downward, rather than being tilted due to the tilt of the winch 205, which causes inaccurate detection, after the all-terrain hanger 100 is fixed on the pile hole foundation 800, the locking bolts are loosened. In this way, the annular ball sleeve 202, the mounting seat 201 and the winch 205 on the mounting seat 201 and other parts are free to swing under the action of gravity until the annular ball sleeve 202 and the connecting ball head 103 do not move relative to each other. At this time, the winch 205 and other components are in a horizontal state. Thereafter, all the locking bolts are tightened to fix the relative position of the annular ball sleeve 202 and the connecting ball head 103, thereby ensuring that the winch 205 remains in a non-tilted state to release the lifting rope 300. This method is mainly aimed at the special-shaped pile hole foundation 800. That is, when the all-terrain hanger 100 is fixed on the special-shaped pile hole foundation 800, it is impossible to ensure that the all-terrain hanger 100 is in a horizontal state. In this way, the winch 205 cannot be ensured to be horizontal. Then, the horizontality of the winch 205 is adjusted by gravity through the articulated connecting parts. Its accuracy is much higher than manual adjustment, and it has the characteristics of simple operation and high correction efficiency.

[0040] As a preferred embodiment of the present invention, Figure 4 、 8 As shown, the guide wheel type inclination angle detection mechanism 500 includes a movable seat 501, a connecting plate 506, a suspension rope inclination sensor, two assembly rods 504, and two guide wheels 505. The two opposite sides of the movable seat 501 are rotatably connected to the mounting seat 201 via shafts 502. A limiting nut 503 is threadedly connected to each shaft 502. The limiting nut 503 facilitates the assembly and disassembly of the movable seat 501 from the mounting seat 201, and the limiting nut 503 does not hinder the movable seat 501 from freely rotating on the mounting seat 201 along the shaft 502. In this embodiment, the two assembly rods 504 are connected to the movable seat 501 and are arranged side by side. The two guide wheels 505 are movably mounted on the two assembly rods 504, and the two guide wheels 505 are arranged side by side. Each guide wheel 505 can rotate along the axis of the corresponding assembly rod 504 and can also slide along the axial direction of the assembly rod 504. In this embodiment, the connecting plate 506 is connected to the same-side ends of the two guide wheels 505. Both guide wheels 505 are rotatably connected to the connecting plate 506. When the guide wheels 505 slide along the axis of the assembly rod 504, the guide wheels 505 can drive the connecting plate 506 to slide together. The suspension rope inclination sensor is mounted on the connecting plate 506. The working principle and advantages of this embodiment are as follows: In this embodiment, the suspension rope 300 extends into the pile hole through the gap between the two guide wheels 505. Therefore, when the suspension rope 300 tilts, the suspension rope 300 directly contacts the guide wheels 505, causing the guide wheels 505 to slide along the axis of the assembly rod 504 and / or the movable seat 501 to rotate a certain angle along the shaft 502. This in turn causes the suspension rope inclination sensor to move, thereby detecting the inclination of the suspension rope 300, thereby facilitating correction of the verticality of the suspension rope 300.

[0041] As a preferred embodiment of the present invention, Figure 5 、 9As shown, the casing 700 includes a cylindrical body 701, the upper end of which is configured with a limiting edge 702, wherein the limiting edge 702 extends radially outward from the cylindrical body 701. Two connecting vertical rods 703 are symmetrically provided at the upper end of the cylindrical body 701, and the two connecting vertical rods 703 are connected to the mounting base 201. Specifically, fixing ears 210 are respectively configured on two opposite sides of the mounting base 201, and a connecting sleeve 211 is configured on each fixing ear 210. The upper ends of the connecting vertical rods 703 extend from the corresponding fixing ears 210 through the connecting sleeve 211, and a positioning bolt is threadedly connected to the connecting sleeve 211. The positioning bolt is tightened so that the end of the positioning bolt is tightly connected to the connecting vertical rod 703, thereby achieving a fixed connection between the connecting vertical rod 703 and the fixing ears 210. This embodiment uses a casing 700 to support the upper end of the pile hole, thereby preventing the occurrence of collapsed debris, soil blocks, etc. at the upper end of the pile hole during the detection process, which may interfere with the suspension rope 300 and / or the pendant detection mechanism 400 and affect the accuracy of the detection.

[0042] As a preferred embodiment of the present invention, Figure 4 As shown, the hoist 205 includes a hoist drum and a drive motor 208. The hoist drum is coaxially connected to a transmission shaft 206, which is rotatably connected to a mounting base 201. The hoist rope 300 is wound around the hoist drum. In this embodiment, a driven pulley 207 is mounted on the transmission shaft 206, a fixed plate 204 is connected to the mounting base 201, and a drive motor 208 is mounted on the fixed plate 204. A driving pulley is mounted on the output shaft of the drive motor 208. The driving pulley and the transmission pulley are connected via a transmission belt 209. In this embodiment, the drive motor 208 is controlled to drive the hoist drum in forward or reverse rotation, thereby unwinding or rewinding the hoist rope 300.

[0043] In a preferred embodiment of the present invention, the pendant detection mechanism 400 is constructed of metal, with a density significantly greater than that of water. This ensures that the pendant detection mechanism 400 can be smoothly inserted into the pile hole for detection. The wires for the dual-axis tilt sensor and multiple ultrasonic sensors mounted on the pendant structure are attached to the suspension rope 300, thus preventing them from becoming disorganized.

[0044] The method of using the present invention comprises the following steps:

[0045] S1. Anchor the all-terrain hanger 100 on the ground at the pile hole to be scanned;

[0046] S2. Afterwards, the articulated connector is controlled to unlock the mounting seat 201. When the hoist 205 is in a horizontal state, the articulated connector is controlled to lock the mounting seat 201 and the all-terrain hanger 100.

[0047] S3, supporting the casing 700 on the inner wall of the pile hole top;

[0048] S4. Pass the end of the suspension rope 300 through the guide wheel type inclination detection mechanism 500, and extend the end of the suspension rope 300 into the pile hole from the center of the pile hole through the pendant type detection mechanism 400;

[0049] S5, controlling the hoisting machine 205 to gradually unwind the suspension rope 300, gradually lowering the pendant-type detection mechanism 400 and detecting the surrounding wall of the pile hole until the pendant-type detection mechanism 400 is released to the bottom of the pile hole;

[0050] S6. After the inspection is completed, the hoist 205 is controlled to reel in the suspension rope 300, and then the all-terrain hanger 100 is removed from the ground.

[0051] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
