Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, and in particular to a steel pipe pile verticality detection device. Background Technology

[0002] During construction, the verticality of steel pipe piles is difficult to control due to geological conditions and the skill level of the workers, easily leading to pile deviation. In practical applications, this causes eccentric compression of the steel pipe piles, resulting in an ultimate bearing capacity far less than the design bearing capacity, thus causing engineering accidents. Therefore, it is necessary to strictly control the construction quality of steel pipe piles, especially the verticality control. Currently, the commonly used methods for detecting the verticality of steel pipe piles are the plumb bob method and the inclinometer method. The plumb bob method uses a plumb bob of a certain length to measure verticality, which can be placed inside or outside the steel pipe pile for measurement. However, this method can only measure the verticality of the part of the steel pipe pile above the ground and has low accuracy. The inclinometer method detects verticality by measuring the angle between the probe and the vertical line. However, there is no groove inside the steel pipe pile to fix the probe direction, making it difficult to keep the probe parallel to the depth direction of the steel pipe pile.

[0003] To address the aforementioned issues, a search revealed, for example, a rapid detection device for the verticality of steel pipe piles provided by patent publication number CN217058723U. The top of a Y-shaped welded steel plate is welded to the bottom center of a top connecting platform. An infrared emitting device is fixedly installed at the top center of the top connecting platform. Two lifting rings are symmetrically welded to both ends of the top connecting platform. Vertical slide rails are welded to each of the Y-shaped welded steel plates at a distance of 1 / 3 from the outer edge. Each vertical slide rail contains two guide sliders. Two layers of support assemblies are erected around the Y-shaped welded steel plate. The upper support assembly is located below the top connecting platform, and the lower support assembly is located at the middle of the vertical direction of the Y-shaped welded steel plate. The inclination of steel pipe piles with different diameters can be detected by adjusting the position of the guide sliders within the vertical slide rails. The infrared emitting device and a laser target placed on top of the pile can detect the inclination orientation and angle of the steel pipe pile at different depths in real time.

[0004] Based on the above search and the findings of existing technologies, existing steel pipe pile verticality testing devices similar to those disclosed above use multiple independent guide sliders to adjust the opening angles of multiple support arms. When testing steel pipe piles with different inner diameters, the adjustment operation is time-consuming and labor-intensive. Therefore, a steel pipe pile verticality testing device is proposed to improve upon these problems. Utility Model Content

[0005] The purpose of this application is to provide a steel pipe pile verticality detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a steel pipe pile verticality detection device, comprising a laser target, a counterweight rod, an infrared emitting device installed at the top of the counterweight rod, and a support assembly installed on the counterweight rod; The support assembly is provided in two sets, and the two sets of support assemblies are symmetrically arranged along the axis of the counterweight rod. The support assembly includes a fixed ring, support arms, rollers, a movable ring, and support rods. The fixed ring is fixedly sleeved on the outside of the counterweight rod. Multiple support arms, rollers, and support rods are provided. Multiple support arms are arranged in a circular array and rotatably mounted on the side end of the fixed ring. Multiple rollers are rotatably mounted on the ends of multiple support arms away from the fixed ring. Multiple support rods are rotatably mounted on the middle of multiple support arms. The movable ring is slidably sleeved on the counterweight rod. The ends of multiple support rods away from the support arms are rotatably mounted on the side end of the movable ring. An adjustment component is provided in the middle of the counterweight bar. The adjustment component is connected to two movable rings to adjust the two movable rings to move closer or further apart synchronously.

[0007] As a further supplement to this solution, the adjustment component includes an external threaded sleeve that is rotatably fitted onto the outside of the counterweight rod. The external threaded sleeve has two opposite threaded sections symmetrically arranged on it. Two movable rings are symmetrically threaded onto the two threaded sections. A limiting guide rod that slides through the fixed ring is fixed on the movable ring.

[0008] As a further supplement to this solution, an operating sleeve is integrally provided in the middle of the external threaded sleeve, and a locking bolt that abuts against the counterweight rod is threaded through the side end of the operating sleeve.

[0009] As a further supplement to this solution, a connecting platform is installed at the top of the counterweight rod, an infrared emitting device is installed on the top surface of the connecting platform, and multiple lifting rings are fixed at equal intervals on the upper surface of the connecting platform.

[0010] As a further supplement to this solution, a buffer structure is provided at the bottom of the counterweight bar.

[0011] As a further supplement to this solution, the buffer structure includes a buffer block and a compression spring. The buffer block is vertically slidably sleeved on the inner side of the bottom end of the counterweight rod, and the compression spring is fixed between the top end of the buffer block and the counterweight rod.

[0012] As a further supplement to this solution, the steel pipe pile verticality detection device also includes a support frame for supporting the laser target.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. In this utility model, by cooperating with the movable ring, the external threaded sleeve and the limiting guide rod, the two movable rings can be moved closer or further apart synchronously by simply rotating the external threaded sleeve, thereby synchronously adjusting the unfolding angle of multiple support arms. When testing steel pipe piles with different inner diameters, the adjustment of the unfolding angle of the support arms is more convenient.

[0014] 2. In this utility model, an operating sleeve is integrated into the middle of the external threaded sleeve. The operating sleeve allows personnel to manually rotate the external threaded sleeve. A locking bolt that abuts against the counterweight rod is threaded through the side end of the operating sleeve. After adjusting the unfolding angle of the support arm, tightening the locking bolt can effectively prevent the external threaded sleeve from rotating unintentionally, thus making the unfolding angle of the support arm less prone to unexpected changes and making the detection more stable and reliable.

[0015] 3. In this utility model, by setting a buffer structure including a buffer block and a compression spring at the bottom of the counterweight rod, when the counterweight rod falls to the bottom of the steel pipe pile, the buffer block and the compression spring can play an effective buffering role, avoiding violent impact that could cause other connecting structures to loosen.

Detailed Implementation

[0019] 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. Example

[0020] refer to Figure 1-4 The steel pipe pile verticality detection device shown includes a laser target 14, a counterweight rod 1, an infrared emitting device 12 installed at the top of the counterweight rod 1, and a support assembly installed on the counterweight rod 1. An adjustment assembly is provided in the middle of the counterweight rod 1 to adjust the support assembly to fit the inner wall of the steel pipe pile 18.

[0021] The counterweight rod 1 has a connecting platform 11 installed at its top, and an infrared emitting device 12 is installed on the top surface of the connecting platform 11. Multiple lifting rings 13 are fixed at equal intervals on the upper surface of the connecting platform 11. The lifting rings 13 are used to connect with the external connecting rope.

[0022] In addition, the steel pipe pile verticality detection device also includes a bracket 15, which is used to support the laser target 14.

[0023] Place the counterweight rod 1 into the steel pipe pile 18. Use the support assembly to ensure that the infrared emitting device 12 is located at the center of the steel pipe pile 18 and that the axis of the entire device coincides with the axis of the steel pipe pile 18. Slowly lower the entire device into the steel pipe pile 18. When the top of the device is below the top of the steel pipe pile 18, ... Figure 4 The laser target 14 is placed vertically, ensuring that the center of the laser target 14 coincides with the center point of the top of the steel pipe pile 18. The device is then slowly lowered into the steel pipe pile 18. During this process, the infrared emitting device 12 continuously emits infrared rays into the laser target 14. By observing the markings on the laser target 14, the distance between the center of the actual steel pipe pile 18 at any depth and its top center, as well as the direction of inclination of the steel pipe pile 18, can be obtained at any time. Once the device is placed at the bottom of the steel pipe pile 18, the distance between the laser markings on the laser target 14 and the center of the laser target 14 is recorded. Using the measured distance between the laser markings on the laser target 14 and the center of the laser target 14, and the length of the steel pipe pile 18, the verticality deviation of the actual steel pipe pile 18 can be calculated.

[0024] The above content is based on existing technology, so it will not be elaborated further here.

[0025] The support assembly consists of two sets, symmetrically arranged along the axial direction of the counterweight rod 1. Each support assembly includes a fixed ring 2, a support arm 3, a roller 4, a movable ring 5, and a support rod 6. The fixed ring 2 is fixedly sleeved on the outside of the counterweight rod 1. Multiple support arms 3, rollers 4, and support rods 6 are correspondingly arranged. Multiple support arms 3 are arranged in a circular array and rotatably mounted on the side end of the fixed ring 2. Multiple rollers 4 are rotatably mounted on the ends of multiple support arms 3 away from the fixed ring 2. Multiple support rods 6 are rotatably mounted on the middle of multiple support arms 3. The movable ring 5 is slidably sleeved on the counterweight rod 1. The ends of multiple support rods 6 away from the support arms 3 are rotatably mounted on the side end of the movable ring 5. An adjustment assembly is connected to two movable rings 5 ​​to adjust the two movable rings 5 ​​to move closer or further away synchronously.

[0026] The adjusting component includes an external threaded sleeve 7 that is rotatably sleeved on the outside of the counterweight rod 1. The external threaded sleeve 7 has two opposite threaded sections symmetrically arranged on it. Two movable rings 5 ​​are symmetrically threaded onto the two threaded sections. A limiting guide rod 8 that slides through the fixed ring 2 is fixed on the movable ring 5.

[0027] Based on the above structural configuration, the two movable rings 5 ​​can be moved closer or further apart synchronously by simply rotating the external threaded sleeve 7, thereby synchronously adjusting the unfolding angle of multiple support arms 3. When testing steel pipe piles 18 with different inner diameters, the adjustment of the unfolding angle of the support arms 3 is more convenient.

[0028] The external threaded sleeve 7 is integrated with an operating sleeve 9 in the middle. The operating sleeve 9 allows personnel to manually rotate the external threaded sleeve 7. The side end of the operating sleeve 9 is threaded with a locking bolt 10 that abuts against the counterweight rod 1. After adjusting the unfolding angle of the support arm 3, tightening the locking bolt 10 can effectively prevent the external threaded sleeve 7 from rotating without human intervention, thus making the unfolding angle of the support arm 3 less prone to accidental changes and making the detection more stable and reliable. Example

[0029] like Figure 2 As shown, a buffer structure is provided at the bottom of the counterweight rod 1. Specifically, the buffer structure includes a buffer block 16 and a compression spring 17. The buffer block 16 is vertically slidably sleeved on the inner side of the bottom end of the counterweight rod 1. The compression spring 17 is fixed between the top of the buffer block 16 and the counterweight rod 1. When the counterweight rod 1 falls to the bottom of the steel pipe pile 18, the buffer block 16 and the compression spring 17 can play an effective buffering role to avoid violent impact that could cause other connecting structures to loosen.
