Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation hole forming, in particular to a positioning device for a pile foundation hole forming detector. Background Art

[0002] The pile foundation hole forming detector is used for comprehensive detection of the hole forming and trench forming quality of various bored piles or underground continuous walls. Large-scale buildings, bridges, ports and offshore projects generally use various deep foundation forms such as bored piles or underground continuous walls. A large number of practices have shown that the hole forming and trench forming quality of pile foundations or underground continuous walls directly affects the pile quality. The hole forming and trench forming detection during the construction stage can not only guide the construction process, but also provide important parameters for pile detection. Therefore, the hole forming quality detection is an important part of pile foundation detection, and its importance cannot be replaced by pile acceptance detection.

[0003] Among them, the existing patent CN2022200495752 is a construction positioning frame for a pile foundation hole detector, which fixes the position of the hole detector by setting a fixed point for storing the hole detector, which can achieve the positioning effect and prevent the hole detector from sliding, resulting in inaccurate measurement results. At the same time, the hole detector centering positioning point is set to cooperate with multiple scales to facilitate the centering positioning of the hole detector. This device can ensure the accurate and efficient positioning of the hole detector, creating favorable conditions for improving construction quality, safety and progress.

[0004] However, the bottom of the positioning device of the pile foundation hole detector for positioning holes generally lacks a moving mechanism. When the positioning device is carried or moved, the staff needs to carry it manually, which is troublesome and laborious.

[0005] There are also a small number of roller structures that are convenient to move. However, although the simple roller structure is convenient to move, it has poor stability when detecting the pile foundation hole. It rolls on the support frame or the ground, thereby affecting the detection accuracy. Therefore, it does not meet the existing needs. In this regard, we propose a positioning device for the pile foundation hole detection instrument. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See attached Figure 1-4 ; An embodiment provided by the utility model:

[0026] A positioning device for a pile foundation hole detector comprises a positioning seat 1 for clamping and fixing the detector, the bottom end surface of the positioning seat 1 is a frame structure, and its frame structure can meet the requirements of the support and installation of the detector, and the middle part can meet the requirements of the detector for pile foundation hole layout detection, the two ends of the positioning seat 1 are respectively provided with displacement seats 2, the outer sides of the displacement seats 2 are provided with fixed seats 3, the structure of the fixed seats 3 can further strengthen the fixation, the two sides of the bottom surface of the displacement seat 2 are movably connected with a liftable pulley block 4, the front and rear sides of the positioning seat 1 are respectively movably connected with handles 6, and the two ends of the handle 6 are respectively provided with transmission components for driving the pulley block 4 to rise and fall.

[0027] During use, if the pile foundation hole is relatively small, the positioning seat can be moved above the pile foundation hole, and then the roller group can be lifted by the lifting handle, so that the bottom end surface is changed from rolling to end surface, which is convenient for fixation. At the same time, through the structure of the bolt hole of the fixing seat, the fixing seat can be fixed by the ground bolt. If the pile foundation hole is relatively large, a guide groove of a steel structure can be laid on the pile foundation hole, and then the roller group of the present application can be pushed along the direction of the guide groove, thereby realizing overhead guidance. When moving into position, the roller group can be lifted by the lifting handle, so that the bottom end surface is changed from rolling to end surface, which is convenient for fixation. Through the structure of the bolt hole of the fixing seat, the fixing seat and the guide groove can be fixed by bolts.

[0028] Furthermore, two guide grooves 101 are provided on both sides of the inner wall of the positioning seat 1, and the guide grooves 101 are T-shaped grooves. The outer end of the fixing seat 3 is provided with bolt holes for auxiliary fixing.

[0029] Furthermore, lifting grooves A201 are provided at the displacement seat 2 at the corresponding positions of the two ends of the handle 6, and the two ends of the bottom end of the handle 6 pass through the lifting grooves A201, and the extended end is installed with a contact block 7 with a tooth surface, and the two ends of the bottom end of the pull rod 6 can be provided with a guide rod, and the end of the guide rod is provided with a threaded section, and the contact block 7 is provided with a threaded hole connected with the threaded section, and the handle 6 will drive the contact block 7 to rise and fall. The transmission assembly includes a transmission gear 5 rotatably installed on both sides of the displacement seat, and the transmission gear 5 is in transmission mesh with the gear surface of the contact block 7.

[0030] Further, the bottom end of the displacement seat 2 is provided with a lifting slot B202, the pulley block 4 includes a lifting rod 401, and the two ends of the bottom end of the lifting rod 401 are respectively installed with pulleys 402, the lifting rod 401 is lifted and lowered in the lifting slot B202, a fixing rod 403 is provided above the lifting rod 401, a screw rod 8 is rotatably installed between the middle part of the fixing rod 403 and the top wall of the lifting slot B202, and a threaded hole 404 rotatably connected to the screw rod 8 is provided on the lifting rod 401.

During the rotation of the transmission gear 5, the transmission rod 501 at the rear end of the transmission gear 5 drives the screw 8 to rotate through the bevel gear 9, so that the pulley group 4 is lifted and lowered on the inner side of the lifting groove B202 during the rotation of the screw 8. When the handle 6 is located at the top of the displacement seat 2, the pulley group 4 is located on the outside of the bottom of the displacement group, so that the staff can move the positioning seat 1 later.

[0032] In summary, when the positioning device is used, firstly, it is checked whether each component is intact. After the inspection is completed, when the handle 6 is lifted, the contact block 7 on one side of the handle 6 drives the transmission gear 5 to rotate through the tooth surface 701, and when the transmission gear 5 is rotating, the transmission rod 501 at the rear end of the transmission gear 5 drives the screw rod 8 to rotate through the bevel gear 9, so that the pulley block 4 performs a lifting movement on the inner side of the lifting groove B202 during the rotation of the screw rod 8;

[0033] When the handle 6 is located at the top of the displacement seat 2, the pulley block 4 is located on the outside of the bottom of the displacement group, so that the staff can move the positioning seat 1 later. After moving to the appropriate position, the handle is pushed down to retract the pulley block 4 to the bottom of the displacement seat 2, so that the staff can fix the position of the positioning seat 1 through the fixed seat 3. Two guide grooves 101 are provided on both sides of the inner wall of the positioning seat 1. The guide grooves 101 are T-shaped grooves, and the pile foundation hole detector is guided and limited by the guide grooves 101 to prevent the pile foundation hole detector from deviating.
