Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically a pile foundation depth measuring device. Background Technology

[0002] In pile foundation engineering, depth measurement is a crucial step in ensuring construction quality and safety. To meet the needs of on-site operations, many pile foundation depth measuring devices are designed to be foldable for easy carrying and storage. However, while this design brings convenience, it also raises some technical challenges, particularly the stability issues caused by the change in the center of gravity when the device is unfolded.

[0003] In the folded state, the components of the measuring device fit together tightly, forming a relatively stable whole. However, when the device is unfolded, the relative positions of the components change, causing the center of gravity to shift. This change in the center of gravity directly affects the stability of the measuring device. In an unstable state, the accuracy of the measurement results can be easily affected. Therefore, it is necessary to design a pile foundation depth measuring device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pile foundation depth measuring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pile foundation depth measuring device, comprising a support member, the support member comprising a first column and a base, a set of the base being installed at the bottom end of the first column, a set of rotatable second columns being installed in the inner cavity on one side of the first column, a clamping assembly being provided at one end of the second column, and a set of sliding and lifting sliders being provided in the inner cavity on the other side of the first column, the second column being rotated by an active drive assembly, the active drive assembly being able to drive the driven drive assembly to operate, thereby enabling the second column to unfold from the inner cavity of the first column while the sliders are lowered.

[0006] Preferably, the active drive component includes a motor and a first gear. One end of the second column rotating rod is connected to the output end of the motor, and the other end of the second column rotating rod is connected to a set of the first gears. The first gears can drive the driven component to operate.

[0007] Preferably, the driven assembly includes a winch, a second gear, and a winding wire. A set of the winches is rotatably mounted on the upper end of the side of the first column cavity away from the second column. One end of the winch rotating rod is connected to the second gear, and the second gear meshes with the first gear. The winch pulls the slider to achieve lifting and lowering through the winding wire.

[0008] Preferably, the first gear and the second gear are covered by a set of protective shells, which are installed on one side of the first column.

[0009] Preferably, two sets of limiting blocks are installed in the inner cavity of the first column corresponding to the slider, and the two sets of limiting blocks form a slide for the slider to slide.

[0010] Preferably, the clamping assembly includes a sliding groove, a first anti-slip pad, a spring, a clamping block, and a second anti-slip pad. A set of the sliding groove is formed at the end of the second column away from the first column. A set of the first anti-slip pads is bonded to the end of the sliding groove away from the main body of the second column. A set of the springs is installed in the cavity at the end of the sliding groove near the main body of the second column. One end of the springs is connected to a set of clamping blocks. A set of the second anti-slip pads is bonded to one side of the clamping blocks corresponding to the first anti-slip pads.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model ensures the synchronicity and coordination of the second column unfolding and the slider lowering actions through the coordinated work of the active drive component and the driven drive component. This design improves the stability of the entire device during the unfolding process and reduces the risk of swaying or tilting caused by changes in the center of gravity.

This makes the device easier to carry and store, and improves space utilization efficiency.

[0013] 2. In order to prevent the gear components from being damaged or contaminated during operation, the first gear and the second gear are covered with a set of protective shells. The protective shells are installed on one side of the first column, which not only provides protection but also keeps the device clean. The slide rail formed by the two sets of limiting blocks provides a stable sliding trajectory for the slider, ensuring the smoothness and accuracy of the slider during the lifting process.

[0014] 3. The design of the slide groove and spring in this utility model allows the clamping assembly to adapt to measuring tools of different sizes, improving the versatility and flexibility of the device.

[0020] 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.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides a pile foundation depth measuring device, including a support member, which includes a first column 15 and a base 16. A set of bases 16 is installed at the bottom end of the first column 15. A set of rotatable second columns 1 is installed in the inner cavity on one side of the first column 15. A clamping component is provided at one end of the second column 1. A set of sliding and lifting sliders 2 is provided in the inner cavity on the other side of the first column 15. The second column 1 can be rotated by an active drive component. The active drive component can drive the driven component to run, so that the second column 1 can be unfolded from the inner cavity of the first column 15 while the sliders 2 are lowered.

[0023] In its initial state, the first column 15 is stably supported on the ground by the base 16, the second column 1 is located inside the cavity of the first column 15 and is in a folded state to reduce the overall space occupied, and the slider 2 is located above the cavity on the other side of the first column 15, ready for lifting and lowering operations.

[0024] When the measuring device needs to be deployed, the active drive component is activated, causing the second column 1 to rotate within the cavity of the first column 15, changing its position from vertical to horizontal. As the second column 1 gradually unfolds, the clamping component is exposed, ready to clamp measuring tools such as laser rangefinders in the prior art. Simultaneously, the active drive component also drives the driven drive component through a linkage mechanism. Under the action of the driven drive component, the slider 2 begins to slide smoothly down the inner wall of the first column 15. This action is synchronized with the unfolding action of the second column 1, ensuring the stability and coordination of the entire device during the unfolding process. When the second column 1 is fully unfolded to the horizontal position, the slider 2 is also lowered to the predetermined height. At this point, the clamping component can clamp the laser rangefinder for measurement operations.

[0025] The coordinated operation of the active and passive drive components ensures the synchronicity and coordination of the unfolding of the second column 1 and the lowering of the slider 2. This design improves the stability of the entire device during the unfolding process and reduces the risk of swaying or tilting caused by changes in the center of gravity. In the folded state, the second column 1 and the slider 2 are compactly housed in the inner cavity of the first column 15, greatly reducing the overall space occupied. This makes the device easier to carry and store, and improves space utilization efficiency.

[0026] Specifically, the active drive component includes a motor 3 and a first gear 4. One end of the rotating rod of the second column 1 is connected to the output end of the motor 3, and the other end of the rotating rod of the second column 1 is connected to a set of first gears 4. The first gears 4 can drive the driven component to run. The driven component includes a winch 5, a second gear 6, and a wire 7. A set of winches 5 is rotatably installed on the upper end of the side of the inner cavity of the first column 15 away from the second column 1. One end of the rotating rod of the winch 5 is connected to the second gear 6. The second gear 6 meshes with the first gear 4. The winch 5 pulls the slider 2 to achieve lifting and lowering through the wire 7. The first gear 4 and the second gear 6 are covered by a set of protective shells 8. The protective shells 8 are installed on one side of the first column 15. Two sets of limiting blocks 9 are installed in the inner cavity of the first column 15 corresponding to the slider 2. The two sets of limiting blocks 9 form a slide for the slider 2 to slide.

[0027] When the device needs to be operated, motor 3 is started, causing the second column 1 to rotate within the cavity of the first column 15. This rotation not only unfolds the second column 1 but also lays the foundation for its subsequent mechanical linkage. As the second column 1 rotates, the first gear 4 also begins to rotate, which drives the second gear 6 to rotate in the opposite direction, driving the winch 5 to rotate. The winch 5 has stranded wire 7 wound on it. When the winch 5 rotates, the stranded wire 7 begins to unwind. The other end of the stranded wire 7 is connected to the slider 2. Therefore, as the stranded wire unwinds, the slider 2 slides down the slide rail formed by the two sets of limiting blocks 9 under the action of gravity. The center of gravity of the entire device will also be lowered accordingly, which helps to increase the stability of the device, especially when performing high-precision measurements, and can reduce errors caused by external interference.

[0028] To prevent damage or contamination of the gear components during operation, the outer covers of the first gear 4 and the second gear 6 are equipped with a set of protective shells 8. The protective shells 8 are installed on one side of the first column 15, which not only provide protection but also keep the device clean. The slides formed by the two sets of limit blocks 9 provide a stable sliding trajectory for the slider 2, ensuring the smoothness and accuracy of the slider 2 during the lifting process.

[0029] The clamping assembly includes a sliding groove 10, a first anti-slip pad 11, a spring 12, a clamping block 13, and a second anti-slip pad 14. A sliding groove 10 is opened at the end of the second column 1 away from the first column 15. A set of first anti-slip pads 11 are glued to the end of the sliding groove 10 away from the main body of the second column 1. A set of springs 12 are installed in the cavity at the end of the sliding groove 10 close to the main body of the second column 1. One end of the springs 12 is connected to a set of clamping blocks 13. A set of second anti-slip pads 14 are glued to one side of the clamping block 13 corresponding to the first anti-slip pad 11.

[0030] When it is necessary to clamp measuring tools such as laser rangefinders onto the clamping assembly, simply place the measuring tool into the slide groove 10 and gently push it towards the main body of the second column 1. At this time, the clamping block 13 will move inward under the pressure of the measuring tool, simultaneously compressing the spring 12. When the measuring tool reaches the appropriate position, release your hand, and the elastic force of the spring 12 will quickly recover, pushing the clamping block 13 away from the main body of the second column 1, thereby firmly clamping the measuring tool. At this time, the first anti-slip pad 11 and the second anti-slip pad 14 are in close contact with the measuring tool, providing additional friction to ensure that the measuring tool will not slip.

[0031] The design of the slide groove 10 and spring 12 allows the clamping assembly to adapt to measuring tools of different sizes, improving the versatility and flexibility of the device. The use of the first anti-slip pad 11 and the second anti-slip pad 14 increases the friction between the measuring tool and the measuring tool, effectively preventing the measuring tool from slipping and ensuring the stability of the clamping. The operation of the clamping assembly is simple and clear. Just put the measuring tool into the slide groove 10 and push it gently to achieve clamping, which greatly improves work efficiency.

[0032] Working principle: When the device needs to be operated, the motor 3 is started, driving the second column 1 to rotate within the cavity of the first column 15. This rotation not only unfolds the second column 1 but also provides the basis for its subsequent mechanical linkage. As the second column 1 rotates, the first gear 4 also begins to rotate, which drives the second gear 6 to rotate in the opposite direction, driving the winch 5 to rotate. The winch 5 has stranded wire 7 wound on it. When the winch 5 rotates, the stranded wire 7 begins to unwind. The other end of the stranded wire 7 is connected to the slider 2. Therefore, as the stranded wire unwinds, the slider 2 will slide down the slide formed by the two sets of limiting blocks 9 under the action of gravity. The center of gravity of the device will also be lowered accordingly. When it is necessary to clamp measuring tools such as laser rangefinders onto the clamping assembly, simply place the measuring tool into the slide groove 10 and gently push it toward the main body of the second column 1. At this time, the clamping block 13 will be squeezed inward by the measuring tool and compress the spring 12. When the measuring tool reaches the appropriate position, release your hand, and the elastic force of the spring 12 will quickly recover, pushing the clamping block 13 away from the main body of the second column 1, thereby tightly clamping the measuring tool. At this time, the first anti-slip pad 11 and the second anti-slip pad 14 are in close contact with the measuring tool, providing additional friction to ensure that the measuring tool will not slip.
