Abstract
Description
Technical Field
[0001] This utility model relates to the field of hole forming detection rod technology, specifically a hole forming detection rod with depth marking and calibration functions. Background Technology
[0002] Hole forming inspection instruments are used for comprehensive inspection of the quality of hole forming and trenching for various cast-in-place piles. Ultrasonic hole forming inspection instruments use ultrasonic reflection technology. In practice, the ultrasonic sensor is lowered at a certain speed along the center of the borehole filled with mud. During the lowering process, ultrasonic pulse reflection signals from the vertical borehole walls in four directions are received and recorded. It is very convenient to monitor the borehole wall condition in four directions at the same time. Parameters such as continuous wall trench width, borehole diameter, verticality, and borehole wall condition can be observed intuitively.
[0003] Hole forming inspection instruments are equipped with a hole forming inspection rod, which can be used for corresponding inspections. However, existing hole forming inspection rods only have the structure of the rod itself, which means that the hole forming inspection rod does not have the functions of depth marking and calibration. As a result, the hole forming inspection rod is not very practical in actual operation. Therefore, corresponding improvements are needed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a hole-forming inspection rod with depth marking and calibration functions to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole-forming detection rod with depth marking and calibration functions, comprising a rod body, a marking ruler mounted on the side surface of the rod body, and a rope connected to the top of the rod body. A mounting plate is mounted on the side surface of the rod body, and a placement groove is formed on the top surface of the mounting plate. A pointer plate is mounted on one side of the bottom inner wall of the placement groove, and a through hole is formed on the other side of the bottom inner wall of the placement groove. A left side plate and a right side plate are mounted on the top of the mounting plate, and a motor is mounted on one side of the right side plate. The output end of the motor is connected to a rotating shaft, and a calibration cable is movably wound around the outer surface of the rotating shaft. A conical block is mounted on one end of the calibration cable.
[0006] Preferably, a through groove is provided inside the right side plate near the rotation shaft, and one end of the rotation shaft passes through the through groove into the inside of the right side plate.
[0007] Preferably, the other end of the rotating shaft is mounted to one side surface of the left side plate via a bearing.
[0008] Preferably, the through hole extends through the interior of the mounting plate, and one end of the calibration cable extends through the through hole into the interior of the mounting plate.
[0009] Preferably, the side surface of the conical block is fitted with an installation ring, and telescopic support rods are installed on both sides of the top surface of the installation ring.
[0010] Preferably, the top ends of both sets of telescopic support rods are installed at the bottom end of the mounting plate.
[0011] Preferably, the bottom end of the rod is tapered, and the mounting plate is semi-circular.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By incorporating components such as a mounting plate, placement slot, pointer plate, through hole, left side plate, right side plate, motor, rotating shaft, calibration cable, conical block, mounting ring, and telescopic support rod, the existing hole-forming detection rod, which only has the structure of the rod body itself, lacks depth marking and calibration functions, resulting in poor practicality in actual operation.
[0014] Using a hole-forming detection instrument, the rope is moved downwards. Because the bottom of the pole is tapered, the pole and the marker ruler can extend into the ground synchronously. The depth of the pole's penetration can be observed in real time through the scale on the marker ruler. When the pole reaches the designated depth, its downward movement stops. Afterwards, the operator starts the motor, causing the rotating shaft to rotate accordingly. This releases the calibration cable from the outer surface of the rotating shaft. Since a conical block is installed at one end of the calibration cable, that end moves downwards under the weight of the conical block. When the bottom surface of the conical block contacts the ground surface, the motor is turned off. Simultaneously with the downward movement of the conical block, the installation ring... As it moves downwards, the two sets of telescopic support rods can extend and retract downwards accordingly. The mounting ring and the two sets of telescopic support rods provide limiting support for the conical block, preventing it from swaying left and right as it moves downwards. Since the calibration cable has length markings and one end of the pointer plate is in contact with the surface of the calibration cable, the distance the conical block has moved downwards can be determined by the length markings on the calibration cable pointed to by the pointer plate. Since the top surface of the marking ruler is in contact with the bottom surface of the mounting plate, the distance the conical block has moved downwards can be subtracted from the total length of the marking ruler to determine the distance the rod extends into the ground. This allows for calibration of the distance the rod has extended into the ground as previously measured by the marking ruler. Attached Figure Description

[0019] 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.
[0020] according to Figures 1-3 As shown, the device includes a rod 1 with a tapered bottom. A marking ruler 11 is mounted on the side surface of the rod 1, and a rope 12 is connected to the top of the rod 1. The marking ruler 11 has depth markings on its side surface to determine the depth of the rod 1 into the ground. A mounting plate 13 is mounted on the side surface of the rod 1, and a placement groove 14 is formed on the top surface of the mounting plate 13. The mounting plate 13 is semi-circular and is positioned on the side surface of the rod 1 above the marking ruler 11, with the top surface of the marking ruler 11 fitting against the bottom surface of the mounting plate 13. A pointer plate 141 is mounted on one side of the bottom inner wall of the placement groove 14, and a through hole 15 is formed on the other side of the bottom inner wall of the placement groove 14. A left side plate 16 and a right side plate 17 are mounted on the top of the plate 13. A motor 18 is mounted on one side of the right side plate 17. The output end of the motor 18 is connected to a rotating shaft 19. A calibration cable 2 is movably wound on the outer surface of the rotating shaft 19. The surface of the calibration cable 2 is marked with length scales. One end of the pointer plate 141 is fitted against the outer surface of the calibration cable 2. A through groove is opened in the interior of the right side plate 17 near the rotating shaft 19. One end of the rotating shaft 19 passes through the through groove into the interior of the right side plate 17. The other end of the rotating shaft 19 is mounted to one side surface of the left side plate 16 through a bearing. A through hole 15 passes through the interior of the mounting plate 13. One end of the calibration cable 2 passes through the through hole 15 into the interior of the mounting plate 13.
[0021] A conical block 21 is installed at one end of the calibration cable 2. An installation ring 22 is installed on the side surface of the conical block 21. Telescopic support rods 23 are installed on both sides of the top surface of the installation ring 22. The top ends of the two sets of telescopic support rods 23 are installed with the bottom end of the mounting plate 13.
[0022] One end of the rope 12 is connected to a hole-forming detection instrument, which allows the rod 1 to be inserted into the ground and tested accordingly.
[0023] In use, the hole-forming detector can be used to extend and retract the rope 12 downwards. Because the bottom of the rod 1 is tapered, the rod 1 and the marker 11 can extend into the ground synchronously. The depth of the rod 1 into the ground can be observed in real time through the scale on the marker 11. When the rod 1 reaches the designated depth, its downward movement can be stopped. Afterwards, the user can start the motor 18, causing the rotating shaft 19 to rotate accordingly. This allows the calibration cable 2 to be released from the outer surface of the rotating shaft 19. Since a conical block 21 is installed at one end of the calibration cable 2, that end moves downwards under the influence of the weight of the conical block 21. When the bottom surface of the conical block 21 contacts the ground surface, the motor 18 can be turned off. Simultaneously with the downward movement of the conical block 21, the installation... The ring 22 moves downwards, allowing the two sets of telescopic support rods 23 to extend and retract downwards. The installation ring 22 and the two sets of telescopic support rods 23 provide a limiting support for the cone block 21, preventing it from swaying left and right as it moves downwards. Since the calibration cable 2 has length markings on its surface and one end of the pointer plate 141 is in contact with the surface of the calibration cable 2, the distance the cone block 21 has moved downwards can be determined by the length markings on the surface of the calibration cable 2 indicated by the pointer plate 141. Since the top surface of the marking ruler 11 is in contact with the bottom surface of the mounting plate 13, the distance the cone block 21 has moved downwards can be subtracted from the total length of the marking ruler 11 to determine the distance the rod 1 extends into the ground. This allows for calibration of the distance the rod 1 has extended into the ground, which was previously measured by the marking ruler 11.
