Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation measurement, in particular to a pile foundation aperture fixed-point measurement device. Background Art

[0002] The pile foundation aperture refers to the diameter of the circular or quasi-circular cavity inside the pile foundation. In civil engineering, the pile foundation is the main load-bearing part supporting the superstructure. The size and quality of its aperture directly affect the safety and stability of the entire building. During the pile foundation design and construction process, the pile foundation aperture needs to be accurately measured and controlled to ensure the safety and stability of the building. Since the pile foundation hole is generally circular, during the measurement process, it is necessary to ensure that the measurement contact is on the diameter of the pile foundation hole in order to measure the accurate pile foundation aperture. Therefore, it is necessary to perform fixed-point measurement operations on the pile foundation aperture.

[0003] In the related technology, during the pile foundation hole diameter measurement process, the staff generally uses measuring tools such as tape measures and media such as rods to place them above the pile foundation mouth to obtain the center of the pile foundation hole, and then uses measuring tools such as tape measures to ensure that the measurement position is on the center of the pile foundation, and performs fixed-point measurement operations on the pile foundation hole diameter to complete the measurement operation.

[0004] However, in the current pile foundation aperture measurement process, when using measuring tools such as tape measures, it is necessary to wait until the center point of the hole diameter is reached through other means, and then measure the pile foundation aperture with the center point as the measurement point. This makes the pile foundation aperture measurement steps more cumbersome, and once the center point is offset, it directly interferes with the measurement results of the pile foundation aperture, affecting the convenience and accuracy of the pile foundation aperture measurement.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 4 The utility model provides a technical solution: a pile foundation aperture fixed-point measuring device, including a measuring sleeve 1 and a measuring fixed-point mechanism, a measuring rod 2 is installed inside the measuring sleeve 1, and the measuring rod 2 and the rear side of the top of the measuring sleeve 1 are inlaid with a scale bar 3. When the measuring sleeve 1 is used in conjunction with the measuring rod 2, the measuring rod 2, the measuring sleeve 1 and the external pile foundation aperture can be contacted and guided to slide to the diameter line of the external pile foundation aperture after stretching, so that the external pile foundation aperture can be accurately measured by coordinating the measuring sleeve 1 and the measuring rod 2 through the scale bar 3 when in use, thereby avoiding the situation where the measurement center point is difficult to accurately determine when the measuring sleeve 1 and the measuring rod 2 are used, resulting in cumbersome and low-precision pile foundation aperture measurement, thereby improving the measurement convenience and accuracy of the measuring sleeve 1 and the measuring rod 2.

[0032] Reference Figure 1-Figure 4In a preferred embodiment, the measuring and fixing mechanism includes a fixed seat 4, which is fixedly connected to the left side of the bottom of the measuring sleeve 1, and a movable seat 5 is fixedly connected to the right side of the bottom of the measuring rod 2. Rolling grooves 6 are opened at the top and bottom of the outer sides of the fixed seat 4 and the movable seat 5. Balls 7 are embedded in the rolling grooves 6. Connecting grooves 8 are opened on both sides of the inside of the measuring sleeve 1. The left sides of both sides of the measuring rod 2 are fixedly connected to connecting blocks 9 located inside the connecting grooves 8. The measuring and positioning mechanism is movably connected to the left side of the top of the measuring rod 2. The handheld measuring sleeve 1 drives the fixed seat 4 to be placed on one side of the inner wall of the pile foundation hole, and makes the bottom of the measuring sleeve 1 contact the top of the outer wall of the pile foundation hole. According to the actual size of the pile foundation hole, the measuring rod 2 is held in hand to drive the movable seat 5 to move, so that the movable seat 5 drives the ball 7 to contact the other side of the inner wall of the pile foundation hole through the rolling groove 6. In this process, after the ball 7 contacts the inner wall of the pile foundation hole, due to the circular inner wall of the pile foundation hole, when the ball 7 outside the fixed seat 4 and the movable seat 5 is not on both sides of the center point of the inner wall of the pile foundation hole, the ball 7 is affected by the arc-shaped guide force of the pile foundation hole wall to rotate. , prompting the fixed seat 4 to cooperate with the movable seat 5 to drive the measuring rod 2 and the measuring sleeve 1 to move toward the center point of the pile foundation hole. When the measuring sleeve 1 and the measuring rod 2 move to the center position of the pile foundation hole, and then move the measuring sleeve 1 and the measuring rod 2, an inward resistance will be applied to the measuring rod 2 and the measuring sleeve 1, allowing the staff to clearly understand the position offset. When the measuring rod 2 and the measuring sleeve 1 move to the center of the pile foundation hole, the pile foundation aperture is measured and read through the scale bar 3 on the top of the measuring rod 2 and the measuring sleeve 1. The measurement and positioning mechanism includes a positioning seat 10, a fixed The positioning plate 11 and the anti-slip pad 12, the positioning seat 10 is movably connected to the left side of the top of the measuring rod 2, the positioning plate 11 is fixedly connected to both sides of the positioning seat 10, and the anti-slip pad 12 is fixedly connected to the bottom of the positioning plate 11. The bottom of the anti-slip pad 12 contacts the top of the measuring sleeve 1, which can provide the user with a medium for positioning the measuring rod 2 and the measuring sleeve 1 when the measuring sleeve 1 is used with the measuring rod 2, thereby avoiding the situation where the measuring sleeve 1 and the measuring rod 2 are difficult to position when used, thereby improving the convenience of positioning the measuring rod 2 and the measuring sleeve 1.

[0033] Reference Figure 2-Figure 4The top of the screw 16 is fixedly connected to the bottom of the rotating frame 14, and the rotating frame 14 can apply a threaded tightening force to the positioning seat 10 to drive the positioning plate 11 to move downward, so as to avoid the situation that the positioning seat 10 is difficult to move downward and tighten the positioning when in use, thereby improving the convenience of the downward movement and tightening positioning of the positioning seat 10.

[0034] Reference Figure 2-Figure 4 In a preferred embodiment, a receiving groove 17 connected to the screw groove 15 is opened on the left side of the interior of the measuring rod 2, and a limit plate 18 is movably connected inside the receiving groove 17. The top of the limit plate 18 is fixedly connected to the bottom of the screw rod 16, which can provide a downward accommodating space for the screw rod 16 when the screw rod 16 is used in conjunction with the positioning seat 10. At the same time, a limiting operation is performed between the screw rod 16 and the screw hole during the upward movement to avoid the situation where the screw 16 is difficult to move downward or excessively move upward and separate from the screw groove 15 when used, thereby improving the flexibility and stability of the use of the screw 16. The left side of the rear side of the top of the measuring rod 2 and the right side of the rear side of the top of the measuring sleeve 1 are fixedly connected with an indicator seat 19. The indicator seat 19 is located on the inner side of the scale bar 3. When the scale bar 3 is used in conjunction with the measuring rod 2 and the measuring sleeve 1, the position of the scale bar 3 between the measuring rod 2 and the measuring sleeve 1 can be read and indicated, thereby avoiding the situation where the scale bar 3 reads the scale number at a position that is inconvenient to accurately observe, thereby improving the convenience of reading the scale bar 3.

[0035] Reference Figure 2-Figure 4In a preferred embodiment, a lifting groove 20 is provided on both sides of the left side of the top of the measuring rod 2, and a lifting rod 21 is movably connected inside the lifting groove 20. The top of the lifting rod 21 is fixedly connected to the bottom of the positioning plate 11, and the screw 16 can be used in conjunction with the positioning plate 11 to perform the lifting connection between the positioning plate 11 and the measuring rod 2, thereby avoiding the position displacement of the positioning plate 11 when in use, thereby improving the stability of the positioning plate 11. The outer side of the inner wall of the connecting groove 8 is inlaid with a magnetic strip 22, and the outer side of the connecting block 9 is inlaid with a magnetic piece 23 magnetically connected to the magnetic strip 22. When the connecting block 9 is used in conjunction with the measuring rod 2, the measuring rod 2 and the measuring sleeve 1 can be magnetically pre-positioned through the connecting block 9, thereby avoiding the difficulty in positioning the measuring rod 2 when in use, thereby improving the convenience of measurement pre-positioning between the measuring rod 2 and the measuring sleeve 1.

[0036] Specifically, the working process or working principle of the pile foundation aperture fixed-point measuring device is as follows: when in use, first hold the rotating frame 14 to drive the screw 16 to rotate and cooperate with the screw groove 15 to apply an upward threaded thrust to the rotating frame 14. At this time, the rotating frame 14 drives the positioning seat 10 to move upward through the rotating cavity 13, and the positioning seat 10 drives the anti-slip pad 12 to rise and separate from the measuring sleeve 1 through the positioning plate 11. At this time, the lifting rod 21 follows the positioning plate 11 to rise inside the lifting groove 20, and the lifting connection between the positioning plate 11 and the measuring rod 2 is stabilized. At the same time, the limit plate 18 follows the screw 16 in the receiving groove 17 moves internally, performs thread activity limit work between the screw rod 16 and the screw groove 15, and then holds the measuring sleeve 1 to drive the fixed seat 4 to be placed on one side of the inner wall of the external pile foundation hole, and makes the bottom of the measuring sleeve 1 contact with the top of the outer wall of the pile foundation hole, performs contact support operation between the measuring sleeve 1 and the pile foundation hole, and then, according to the actual size of the external pile foundation hole, holds the measuring rod 2 to drive the movable seat 5 to move, so that the movable seat 5 drives the ball 7 to contact the other side of the inner wall of the pile foundation hole through the rolling groove 6. At this time, the connecting block 9 follows the measuring rod 2 to move inside the connecting groove 8, and the measuring rod 2 and the measuring sleeve 1 are connected. The sliding connection support work is performed between them. During this process, after the ball 7 contacts the inner wall of the pile foundation hole, since the inner wall of the pile foundation hole is circular, when the ball 7 outside the fixed seat 4 and the movable seat 5 is not on both sides of the center point of the inner wall of the pile foundation hole, the ball 7 is affected by the arc-shaped guide force of the pile foundation hole wall to rotate, prompting the fixed seat 4 to cooperate with the movable seat 5 to drive the measuring rod 2 and the measuring sleeve 1 to move toward the center point of the pile foundation hole. When the measuring sleeve 1 and the measuring rod 2 move to the center position of the pile foundation hole, when the measuring sleeve 1 and the measuring rod 2 are moved to the center position of the pile foundation hole, an inward resistance will be applied to the measuring rod 2 and the measuring sleeve 1, allowing the work to proceed. The personnel clearly understand the position offset. When the measuring rod 2 and the measuring sleeve 1 are moved to the center of the pile foundation hole, the connecting block 9 performs magnetic attraction positioning work between the stretched measuring rod and the measuring sleeve through the magnetic strip 22 and the magnetic sheet 23. During this process, the indicating seat 19 on the top of the measuring rod 2 moves with the measuring rod 2 to indicate the scale bar 3 on the top of the measuring sleeve 1. At the same time, the indicating seat 19 on the top of the measuring sleeve 1 indicates the scale bar 3 on the top of the measuring rod 2. The data of the pile foundation aperture can be obtained by adding the scales of the measuring rod 2 and the scale bar 3 indicated by the indicating seat 19 on the top of the measuring sleeve 1.
