Description

Technical Field

[0001] This utility model relates to the field of pile foundation hole depth measurement technology, and in particular to a pile foundation hole depth measurement device for pile foundation construction. Background Technology

[0002] A device for measuring the depth of pile foundation holes used in pile foundation construction. First, a pile foundation is a deep foundation consisting of piles and pile caps connecting the pile tops, or a single pile foundation consisting of columns connected to the piles, referred to simply as a pile foundation. If the entire pile body is buried in the soil and the bottom surface of the pile cap is in contact with the soil, it is called a low-pile-cap pile foundation; if the upper part of the pile body is exposed above the ground and the bottom of the pile cap is above the ground, it is called a high-pile-cap pile foundation. Building pile foundations are usually low-pile-cap pile foundations. Pile foundation holes are holes drilled for cast-in-place concrete piles to reinforce underground foundations and improve the load-bearing capacity and seismic resistance of building foundations.

[0003] A search revealed a device for measuring the depth of pile foundation holes in pile foundation construction (authorization announcement number: CN 218496002U), which "includes a bucket body and a sliding bucket. A level is fixedly connected to the right side of the bucket body, a motor is fixedly connected to the upper middle part of the bucket body, a connecting rod is fixedly connected to the outer wall of the lower drive end of the motor, a lifting ring is fixedly connected to the lower end of the connecting rod, a lifting plate is threadedly connected inside the lifting ring, and a sliding groove is provided in the middle of the bottom end of the bucket body. In this utility model, the support legs are first adjusted, which can be observed through the level. If it is unbalanced, the level can be adjusted by turning the knob until the bucket body is in a stable state, so as not to tilt and cause inaccurate readings, thus reducing errors. The motor is then started. The rotation of the motor drives the connecting rod and the lifting ring to rotate to the scale plate fixed to the lifting plate for lifting and lowering. This facilitates operation, avoids the time-consuming and laborious manual measurement, and improves work efficiency."

[0004] Based on the aforementioned technologies, the applicant believes that the support legs in the aforementioned technologies are vertically set, and the overall center of the device is biased upwards, which may lead to instability during use. In order to address the above problems, we have introduced a pile foundation hole depth measuring device for pile foundation construction. Utility Model Content

[0005] This utility model discloses a pile foundation hole depth measuring device for pile foundation construction, which aims to solve the technical problem that the support legs are set vertically and the overall center of the device is biased upward, resulting in instability during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0028] The pile foundation hole depth measuring device disclosed in this utility model is mainly used in the scenario of measuring the depth of pile foundation holes.

[0029] Reference Figure 1 - Figure 4 A pile foundation hole depth measuring device for pile foundation construction includes a fixed sleeve 1, a support ring 3 fixedly connected to the top of the fixed sleeve 1, a threaded block 2 rotatably connected to the top of the support ring 3, a measuring mechanism provided on the outside of the fixed sleeve 1, the measuring mechanism including a measuring component and a stabilizing component, the measuring component and the stabilizing component working together, the measuring component including a measuring rod 41, the measuring rod 41 being disposed inside the threaded block 2, a first threaded groove 42 being opened on the outside of the measuring rod 41, the threaded block 2 being threadedly connected to the measuring rod 41, an installation groove 43 being opened on the top of the measuring rod 41, an internal threaded groove 44 being provided inside the installation groove 43, and an installation head 45 fixedly connected to the bottom of the measuring rod 41, the installation head 45 working together with the installation groove 43. The stabilizing component includes a gear ring 51, which is fixedly connected to the outside of the threaded block 2. A fixed frame 52 is fixedly connected to the outside of the fixed sleeve 1. A motor 53 is fixedly connected inside the fixed frame 52. The output end of the motor 53 extends to the outside of the fixed frame 52 and is fixedly connected to a gear 54. The gear 54 and the gear ring 51 are meshed together. Rotating blocks 56 are fixedly connected in a circular array to the outside of the fixed sleeve 1. A rotating frame 55 is rotatably connected in a circular array to the outside of the supporting ring 3. A support leg 57 is rotatably connected inside the rotating block 56. The support leg 57 is rotatably connected to the rotating frame 55.

[0030] In this embodiment: the measuring rod 41 is inserted into the threaded block 2, the motor 53 is started, the output end of the motor 53 rotates and drives the gear 54 to rotate, the gear 54 rotates and drives the gear ring 51 to rotate, the gear ring 51 rotates and drives the threaded block 2 to rotate, the threaded block 2 rotates and drives the measuring rod 41 to move downward. When the length is insufficient, multiple measuring rods 41 can be assembled through the set mounting head 45 and internal thread groove 44. The size of each measuring rod 41 is fixed, so the depth of the foundation pile hole can be calculated by calculating the number of measuring rods 41. Through the set measuring mechanism, the depth of the foundation pile hole can be quickly measured, which can be adapted to the measurement of the depth of foundation pile holes with greater depth. At the same time, under the support of the support leg 57, the center is relatively stable and there will be no shaking. The structure is simple and has strong practicality.

[0031] In the above technical solution, considering that the support leg 57 is set vertically and the overall center of the device is slightly upward, there will be a problem of instability during use. To solve this problem, the specific operation is as follows:

[0032] Reference Figure 1 - Figure 4 In a preferred embodiment, the bottom of the support leg 57 is rotatably connected to a foot 6, which is circular in shape. A rubber pad 7 for anti-slip is fixedly connected to the bottom of the foot 6. The size of the mounting head 45 matches the size of the mounting groove 43, and the mounting head 45 and the mounting groove 43 are threaded together. The motor 53 is electrically connected to an external controller.

[0033] In this embodiment: the base 6 increases the contact area between the support leg 57 and the ground, thereby increasing stability; the rubber pad 7 increases the friction between the base 6 and the ground; the size of the mounting head 45 matches the size of the mounting groove 43, allowing for quick connection between the mounting head 45 and the mounting groove 43 and preventing shaking; the controller allows operators to easily control the opening and closing of the motor 53, making operation simpler.

[0034] Working principle: In actual use, the operator first places the support leg 57 vertically on the ground, so that the fixed sleeve 1 and the pile hole are concentric. Then, the measuring rod 41 is inserted into the threaded block 2, and the motor 53 is started. The output end of the motor 53 rotates, which drives the gear 54 to rotate. The gear 54 rotates, which drives the gear ring 51 to rotate. The gear ring 51 rotates, which drives the threaded block 2 to rotate. The rotation of the threaded block 2 drives the measuring rod 41 to move downward. When the length is insufficient, multiple measuring rods 41 can be assembled through the set mounting head 45 and internal thread groove 44. The size of each measuring rod 41 is fixed. Therefore, the depth of the pile hole can be calculated by counting the number of measuring rods 41.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
