Description

Technical Field

[0001] This utility model relates to the field of pile hole diameter detection technology, and in particular to a pile hole diameter detection device for engineering management. Background Technology

[0002] During the construction process, a solid foundation needs to be built first. During the foundation construction, pile holes need to be excavated, and then cement steel cages are added into the pile holes to form cement columns, which can provide stable support for the building. After the pile holes are excavated, it is necessary to check whether the diameter of the pile holes meets the requirements.

[0003] A search revealed a Chinese patent publication number CN221549561U, which discloses a pile hole diameter detection device for engineering management. The device includes a main structural tube, a movable sleeve and a spring fitted onto the surface of the main structural tube. The movable sleeve can slide vertically along the outer surface of the main structural tube. One end of the movable sleeve is fixedly connected to the end of the spring. An upper fixing plate is fixed to the end of the main structural tube, and the upper fixing plate is fixedly connected to the spring on the side facing the spring. A movable support structure is provided between the main structural tube and the movable sleeve. This patent, by incorporating a movable sleeve, spring, upper fixing plate, movable pull ring, upper fixing block, lower fixing block, first push rod, second push rod, and inner wall support rod, automatically determines the center of the pile hole. This solves the problem of cumbersome and inaccurate manual measurement, which requires multiple measurements to determine the center and then accurate measurements using a tape measure or ruler to ensure accuracy. However, when inserting it into the pile hole, it is necessary to manually maintain the position of the movable sleeve to ensure the retracted state of the inner wall support rod, which is inconvenient to operate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Example 1: A pile hole diameter detection device for engineering management, such as... Figures 1 to 3 As shown, the device includes a central tube 1, a movable sleeve 2 that slides on the outer wall of the central tube 1, and annular protrusions on the top sidewalls of both the central tube 1 and the movable sleeve 2. A spring 3 is fitted on the outer wall of the central tube 1, with both ends of the spring 3 connected to the annular protrusions on the central tube 1 and the movable sleeve 2, respectively. Multiple guide grooves are provided on the sidewall of the central tube 1, and a fixing frame 4 slides on the inner wall of the central tube 1. The fixing frame 4 passes through the guide grooves and is connected to the movable sleeve 2. A connecting rod 5 is rotatably connected to the top of the fixing frame 4, and a handle 6 is fixedly connected to the top of the connecting rod 5. A limit block 7 is fixedly connected to the sidewall of the connecting rod 5. A through hole 8 that slides on the connecting rod 5 is provided at the top of the central tube 1, and an avoidance groove 9 is provided on the sidewall of the through hole 8.

[0021] The central tube 1 has multiple connecting rods 10 rotatably connected to its side wall. The multiple connecting rods 10 are arranged circumferentially. The other end of the connecting rod 10 is rotatably connected to a support rod 12. The side wall of the connecting rod 10 is rotatably connected to a connecting rod 11. The other end of the connecting rod 11 is rotatably connected to the movable sleeve 2.

[0022] During testing, the user holds the central tube 1 with one hand and pulls the handle 6 upward with the other. The connecting rod 5 drives the movable sleeve 2 upward through the fixing frame 4 until the limiting block 7 passes through the relief groove 9 and moves out of the central tube 1. Then, the handle 6 is rotated to make the limiting block 7 and the relief groove 9 misaligned. At this time, the handle 6 is released to temporarily lock the position of the movable sleeve 2. Then, the entire device is placed into the pile hole. The handle 6 is rotated to align the limiting block 7 and the relief groove 9, and the movable sleeve 2 is unlocked. The spring 3 pushes the movable sleeve 2 to move, and through the connecting rod 10 and the connecting rod 21, it pushes the support rod 12 to move towards the inner wall of the pile hole until the support rod 12 is in contact with the inner wall of the pile hole.

[0023] By providing a fixed frame 4, connecting rod 5, handle 6, limiting block 7, through hole 8, and clearance groove 9, the position of the movable sleeve 2 can be temporarily locked before the device is placed into the pile hole, making it convenient to place the device into the pile hole and easy to operate.

[0024] Example 2: A pile hole diameter detection device for engineering management. This example is based on Example 1 and makes the following improvements, such as... Figure 1 , Figure 4 As shown, two fixed rods 13 are fixedly connected to the top side wall of the central tube 1. The two fixed rods 13 are located on the same straight line. A slider 15 is slidably connected to the inner wall of the fixed rod 13. A linkage rod 14 is fixedly connected to the bottom of the slider 15. The linkage rod 14 is vertically slidably engaged with the support rod 12. A sliding groove 16 is opened on the side wall of the fixed rod 13. The slider 15 is slidably connected to the inner wall of the sliding groove 16. A scale 17 is provided on the side wall of the fixed rod 13. The scales 17 on the two fixed rods 13 face opposite directions. A pointer 18 that cooperates with the scale 17 is fixedly connected to the side wall of the slider 15.

[0025] When the support rod 12 moves, it will drive the linkage rod 14 to move, causing the slider 15 to slide along the fixed rod 13. When the support rod 12 is in contact with the inner wall of the pile hole, the distance between one support rod 12 and the axis of the central tube 1 can be read by observing the relative position of the pointer 18 and the scale 17. Multiplying the reading by two gives the diameter of the pile hole. Since the scale 17 on the two fixed rods 13 faces opposite directions, the user does not need to pay special attention to the orientation of the scale 17 when using it. Just make sure that either side of the fixed rod 13 is facing you, and you can take the reading.

[0026] By setting up a fixed rod 13, a linkage rod 14, a slider 15, a sliding groove 16, a scale 17, and a pointer 18, the distance between a support rod 12 and the axis of the central tube 1 can be read by observing the relative position of the pointer 18 and the scale 17. Multiplying the reading by two gives the diameter of the pile hole, further improving the convenience of use.

[0027] By setting two fixed rods 13 with the scales 17 on the two fixed rods 13 facing opposite directions, the user does not need to pay special attention to the orientation of the scales 17 during use. They only need to ensure that either side of the fixed rod 13 is facing them to take the reading, which is convenient for operation.

[0028] Working principle: During testing, the user holds the central tube 1 with one hand and pulls the handle 6 upwards with the other. The connecting rod 5 drives the movable sleeve 2 upwards through the fixing frame 4 until the limiting block 7 passes through the clearance groove 9 and moves out of the central tube 1. Then, the handle 6 is rotated to misalign the limiting block 7 with the clearance groove 9. At this point, the handle 6 is released, which can temporarily lock the position of the movable sleeve 2. Then, the entire device is placed into the pile hole. The handle 6 is rotated, and the limiting block 7 and the clearance groove 9 are aligned. The movable sleeve 2 is released from its lock, and the spring 3 pushes the movable sleeve 2 to move. Through the connecting rod 10 and the connecting rod 21, the support rod 12 is pushed to move towards the inner wall of the pile hole. The movement continues until the support rod 12 is in contact with the inner wall of the pile hole. As the support rod 12 moves, it will drive the linkage rod 14 to move, causing the slider 15 to slide along the fixed rod 13. After the support rod 12 is in contact with the inner wall of the pile hole, the distance between one support rod 12 and the axis of the central tube 1 can be read by observing the relative position of the pointer 18 and the scale 17. Multiplying the reading by two gives the diameter of the pile hole. Since the scales 17 on the two fixed rods 13 face opposite directions, the user does not need to pay special attention to the orientation of the scales 17 when using them. The user only needs to ensure that either side of the fixed rod 13 faces the user to take the reading.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
