Description

Technical Field

[0001] This utility model relates to a bridge pile foundation testing device, specifically a grouting pile hole inspection device. Background Technology

[0002] In bridge construction, the construction quality of cast-in-place piles is crucial to the safety and stability of the project. Strict control of parameters such as pile diameter and verticality is necessary during pile foundation construction; therefore, accurate testing of the pile foundation before lowering the reinforcing cage and pouring concrete is an essential step.

[0003] However, most existing borehole inspection tools for cast-in-place piles suffer from inconvenient storage. Traditional inspection tools typically employ a fixed structure design, resulting in a large volume that cannot be effectively folded or compressed, thus occupying a significant amount of space when not in use. This design not only increases transportation costs but also complicates equipment storage on construction sites. Especially in space-constrained working environments, the storage and handling of inspection tools becomes a major challenge for construction workers. Furthermore, due to their large size, inspection tools are susceptible to damage from external impacts during transportation, further increasing equipment maintenance costs. Summary of the Invention

[0004] The purpose of this utility model is to provide a hole inspection device for cast-in-place piles to solve the problem of inconvenience in storage and transportation in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bored pile inspection device, comprising:

[0007] The device comprises a central column, multiple measuring components, and multiple first connectors. Each measuring component is mounted on the central column at intervals along the axial direction of the central column. Each first connector is arranged along the axial direction of the central column and is evenly distributed along the circumference of the central column. Each first connector is detachably connected to each measuring component.

[0008] Each of the measuring components includes a first ring and a plurality of support components. Each of the support components is evenly distributed along the circumferential direction of the central column, and one end of each support component is rotatably mounted on the central column, while the other end is detachably connected to the first ring.

[0009] Each of the support components has an extended state arranged in the radial direction of the central column and a retracted state arranged in the axial direction of the central column. Each of the support components can switch between the extended state and the retracted state during rotation.

[0010] According to the above technical means, the support component is in an unfolded state along the radial direction of the central column when in use, which can be used to detect the size of the hole. When not in use, the support component is in a retracted state along the axial direction of the central column, which greatly reduces the overall volume of the hole detector, making it easy to store and fold when not in use. At the same time, it reduces the space occupied during transportation, reduces transportation costs, and improves construction efficiency.

[0011] In this invention, each measuring component is evenly distributed along the circumference of the central column via a first connector, and the connection method is a detachable design. At the same time, both the first connector and the first ring are detachably installed on the central column, making the assembly and disassembly of the hole detector more convenient and quick, improving the operating efficiency of construction personnel, and reducing on-site preparation time.

[0012] Furthermore, it also includes multiple second connectors; a support seat is formed on the central column corresponding to each of the support components, and one end of each support component is rotatably connected to the corresponding support seat through one of the second connectors, so that one end of each support component is rotatably mounted on the central column.

[0013] According to the aforementioned technical means, the support component is connected to the support base via a second connector. This rotatable connection method makes the support component more flexible during deployment and retraction. Operators can easily adjust the angle of the support component, allowing it to better fit the inner wall of the pile hole when deployed and to tightly fit the central column when retracted, reducing space occupation. This flexibility not only improves operational convenience but also reduces operational errors caused by structural limitations.

[0014] Furthermore, each of the support bases has a first inclined surface, and each of the support components has a second inclined surface at one end. The first inclined surface and the second inclined surface are disposed opposite to each other. The second connector is located inside the support base and the support component and passes through the first inclined surface and the second inclined surface. The second connector is used to keep the first inclined surface and the second inclined surface in contact when the support component and the support base rotate relative to each other.

[0015] According to the above technical means, by setting a first inclined surface on the support base and a second inclined surface at one end of the support component, the two are rotatably connected by a second connector, and the support component can switch between an unfolded state and a retracted state through the first inclined surface and the second inclined surface, so that the support component can be unfolded or retracted.

[0016] Furthermore, each of the support components includes a first support arm and a second support arm. One end of the first support arm is rotatably mounted on the support base via the second connector. The first support arm is sleeved on the second support arm, and the second support arm is movable within the first support arm to change the length of each of the support components.

[0017] According to the above-mentioned technical means, the support component includes a first support arm sleeved on a second support arm, and the second support arm can move within the first support arm, thereby realizing the adjustability of the length of the support component, enabling the borehole inspector to adapt to pile foundations of different diameters, and further improving the versatility and flexibility of the borehole inspector.

[0018] Furthermore, a plurality of first snap-fit ​​members are formed on the first support arm, and the plurality of first snap-fit ​​members are evenly distributed along the length direction of the first support arm; a second snap-fit ​​member is formed on the second support arm, and the second snap-fit ​​member can engage with each of the first snap-fit ​​members to lock the length of the support assembly.

[0019] Based on the aforementioned technical means, by setting multiple first locking components on the first support arm and second locking components on the second support arm, the length of the support assembly can be locked at multiple preset positions. This allows for precise adjustment and locking of the support assembly length according to actual testing needs, thereby improving the accuracy and reliability of the measurement. The design of the locking components makes the length adjustment and locking operation of the support assembly simple and quick, requiring no complex tools or hole detectors. The length adjustment and locking can be completed manually, greatly improving the convenience and efficiency of the operation.

[0020] Furthermore, a clamping component is formed on the other end of each of the support components, and the clamping component is detachably connected to the first ring and the first connector respectively.

[0021] According to the above-mentioned technical means, the measuring component can be quickly fixed on the first ring by the clamping component and connected to other measuring components by the first connector. This simplifies the assembly and disassembly process of the hole detector, improves the flexibility and reliability of the connection, enhances the versatility and adaptability of the hole detector, improves the durability and maintainability of the hole detector, further improves construction efficiency, and reduces measurement errors caused by improper assembly.

[0022] Furthermore, the clamping assembly includes two clamps, which are arranged opposite to each other, and a first clamping groove is formed between the two clamps. The first clamping groove is used to clamp the first connector.

[0023] According to the above technical means, by setting two clamps and forming a first clamping groove between the two clamps, the first connector can be detachably installed between the two clamps and form a stable connection structure. This not only reduces the measurement error caused by loose connection, but also enhances the stability of the entire hole detector during use, ensuring the accuracy and reliability of the measurement results.

[0024] Furthermore, each of the clamps is also provided with a second clamping groove, which is used to clamp the first ring.

[0025] Based on the above technical means, by designing fixtures, each fixture also has a second clamping groove to clamp the first ring, making the installation and disassembly process of the first ring simpler and faster. The first ring can be quickly fixed on the measuring component through the second clamping groove on the fixture without complicated tools.

[0026] Furthermore, it also includes a lifting ring at one end of the central column.

[0027] Based on the above-mentioned technical means, the design of the lifting ring makes the hole inspector more convenient to lift and transport. The hole inspector can be lifted by the lifting ring, avoiding damage or deformation that may be caused by direct contact with the hole inspector body. This not only improves the transportation efficiency of the hole inspector, but also reduces the risk of damage to the hole inspector due to improper handling.

[0028] Furthermore, it also includes a guide member, which is installed at the end of the central column away from the lifting ring.

[0029] Based on the above technical means, the setting of the first guide component can play a good guiding role, enabling the hole inspector to enter the pile hole more smoothly, reducing the jamming caused by irregular or tilted hole openings, which helps to improve the entry efficiency of the hole inspector and ensure that it can accurately reach the predetermined position.

[0030] The beneficial effects of this utility model are:

[0031] 1. When in use, the support assembly is in an unfolded state along the radial direction of the central column, which can be used to detect the size of the hole. When not in use, the support assembly is in a retracted state along the axial direction of the central column, which greatly reduces the overall volume of the hole detector. This allows the hole detector to be easily stored and tucked away when not in use, while also reducing the space occupied during transportation, reducing transportation costs, and improving construction efficiency.

[0032] 2. In this utility model, each measuring component is evenly distributed along the circumference of the central column through the first connecting member, and the connection method is a detachable design, which makes the assembly and disassembly of the hole inspector more convenient and quick, improves the operating efficiency of construction personnel, and reduces on-site preparation time.

Detailed Implementation

[0041] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0043] like Figure 1As shown in the figure, this embodiment proposes a bored pile inspection device, including: a central column 1, multiple measuring components 2 and multiple first connecting members 3 (the multiple in this utility model refers to two or more), each measuring component 2 is installed at intervals on the central column 1 along the axial direction of the central column 1; each first connecting member 3 is arranged along the axial direction of the central column 1 and is evenly distributed along the circumference of the central column 1, and each first connecting member 3 is detachably connected to each measuring component 2; each measuring component 2 includes a first ring 4 and multiple support components 5, each support component 5 is evenly distributed along the circumference of the central column 1, and one end of each support component 5 is detachably connected to the first ring 4; each support component 5 has an unfolded state arranged along the radial direction of the central column 1 and a retracted state arranged along the axial direction of the central column 1, and each support component 5 can switch between the unfolded state and the retracted state during rotation.

[0044] like Figure 1 As shown, in this embodiment, the installation process of a bored pile borehole detector is as follows: First, rotate each support component 5 from the retracted state to the unfolded state. Then, install each first ring 4 on the corresponding support component 5 to install multiple measuring components 2 on the central column 1. Then, install multiple first connectors 3 on the multiple measuring components 2 to form a cage shape for detecting the borehole diameter. The disassembly process is as follows: First, remove the multiple first connectors 3 from the multiple measuring components 2. Then, remove each first ring 4 from the corresponding support component 5. Finally, rotate each support component 5 from the unfolded state to the retracted state to store the borehole detector. During use, each support component 5 is in the unfolded state; when not in use, each support component 5 is in the retracted state, facilitating storage and transportation.

[0045] When in use, the support component 5 is in an unfolded state arranged along the radial direction of the central column 1, which can be used to detect the size of the hole. When not in use, the support component 5 is in a retracted state arranged along the axial direction of the central column 1, which greatly reduces the overall volume of the hole detector, making it easy to store and fold the hole detector when not in use. At the same time, it reduces the space occupied during transportation, reduces transportation costs, and improves construction efficiency.

[0046] In this embodiment, each measuring component 2 is evenly distributed along the circumference of the central column 1 via the first connector 3, and the connection method is a detachable design, which makes the assembly and disassembly of the hole detector more convenient and quick, improves the operating efficiency of construction personnel, and reduces on-site preparation time.

[0047] like Figures 2-4As shown, this embodiment also includes multiple second connectors 6; a support seat 7 is formed on the central column 1 corresponding to each support component (5), and one end of each support component 5 is rotatably connected to the corresponding support seat (7) through one of the second connectors 6, so that one end of each support component 5 is rotatably mounted on the central column 1. The support component 5 is connected to the support seat 7 through the second connector 6. This rotatable connection method makes the support component 5 more flexible in the process of unfolding and retracting, and the angle of the support component 5 can be easily adjusted so that it can better fit the inner wall of the pile hole when unfolded, and can fit tightly against the central column 1 when retracted, reducing space occupation. This flexibility not only improves the convenience of operation, but also reduces operational errors caused by structural limitations.

[0048] In this preferred embodiment, the second connecting member 6 is a spring bolt. One end of the spring bolt is embedded in each support base 7, and the other end is embedded in each support component 5. During the rotation of each support component 5, the spring bolt can be compressed or released. The spring bolt can move within each support base 7 and each support component 5, and prevent each support component 5 from detaching from each support base 7.

[0049] like Figure 4 As shown, in this embodiment, each support base 7 has a first inclined surface 71, and each support component 5 has a second inclined surface 51 at one end. The first inclined surface 71 and the second inclined surface 51 are disposed opposite to each other. The second connecting member 6 is located inside the support base 7 and the support component 5, and passes through the first inclined surface 71 and the second inclined surface 51. The second connecting member 6 is used to keep the first inclined surface 71 and the second inclined surface 51 in contact when the support component 5 rotates relative to the support base 7. By providing the first inclined surface 71 on the support base 7 and the second inclined surface 51 at one end of the support component 5, and rotatably connecting the two through the second connecting member 6, the support component 5 can switch between an unfolded state and a retracted state through the first inclined surface 71 and the second inclined surface 51, so that the support component 5 can be unfolded or retracted.

[0050] In this preferred embodiment, the inclination angle of the first inclined surface 71 and the second inclined surface 51 is 45 degrees.

[0051] In this embodiment, when each support component 5 is in the unfolded state, the first inclined surface 71 and the second inclined surface 51 are adapted to each other, and each support base 7 is at a 180-degree angle to each support component 5; when each support component 5 is in the retracted state, the first inclined surface 71 and the second inclined surface 51 are adapted to each other, and each support base 7 is at a 90-degree angle to the corresponding support component 5.

[0052] like Figure 2As shown, in this embodiment, each support component 5 includes a first support arm 8 and a second support arm 9. One end of the first support arm 8 is rotatably mounted on the support base 7 via a second connector 6. The first support arm 8 is sleeved on the second support arm 9, and the second support arm 9 can move within the first support arm 8 to change the length of each support component 5. The support component 5, with the first support arm 8 sleeved on the second support arm 9 and the second support arm 9 movable within the first support arm 8, achieves adjustable length of the support component 5, enabling the borehole inspector to adapt to pile foundations of different diameters, further improving the versatility and flexibility of the borehole inspector.

[0053] like Figure 5 As shown, in this embodiment, a plurality of first snap-fit ​​members 10 are formed on the first support arm 8, and the plurality of first snap-fit ​​members 10 are evenly distributed along the length direction of the first support arm 8; a second snap-fit ​​member 11 is formed on the second support arm 9, and the second snap-fit ​​member 11 can snap-fit ​​with each of the first snap-fit ​​members 10 to lock the length of the support component 5.

[0054] By setting multiple first locking elements 10 on the first support arm 8 and second locking elements 11 on the second support arm 9, the length of the support component 5 can be locked at multiple preset positions. This allows for precise adjustment and locking of the length of the support component 5 according to actual testing requirements, thereby improving the accuracy and reliability of the measurement. The locking element design makes the length adjustment and locking operation of the support component 5 simple and quick, without the need for complex tools or hole detectors. The length adjustment and locking can be completed manually, greatly improving the convenience and efficiency of the operation.

[0055] like Figure 6 As shown, in this embodiment, a clamping component 12 is formed on the other end of each support component 5. The clamping component 12 is detachably connected to the first ring 4 and the first connecting member 3, respectively. The measuring component 2 can be quickly fixed on the first ring 4 by the clamping component 12 and connected to other measuring components 2 by the first connecting member 3. This simplifies the assembly and disassembly process of the hole detector, improves the flexibility and reliability of the connection, enhances the versatility and adaptability of the hole detector, improves the durability and maintainability of the hole detector, further improves construction efficiency, and reduces measurement errors caused by improper assembly.

[0056] like Figure 6As shown, in this embodiment, the clamping assembly 12 includes two clamps 13, which are arranged opposite to each other. A first clamping groove 14 is formed between the two clamps 13, and the first clamping groove 14 is used to clamp the first connector 3. By setting two clamps 13, which are arranged opposite to each other, and forming a first clamping groove 14 between the two clamps 13 to clamp the first connector 3, the first connector 3 can be detachably installed between the two clamps 13, forming a stable connection structure. This not only reduces measurement errors caused by loose connections, but also enhances the stability of the entire hole detector during use, ensuring the accuracy and reliability of the measurement results.

[0057] like Figure 7 As shown, in this embodiment, each clamp 13 also has a second clamping groove 15, which is used to clamp the first ring 4. By designing the clamp 13, each clamp 13 also has a second clamping groove 15 to clamp the first ring 4, making the installation and removal process of the first ring 4 simpler and faster. The first ring 4 can be quickly fixed on the measuring component 2 by the second clamping groove 15 on the clamp 13 without the need for complicated tools.

[0058] like Figure 1 As shown, this embodiment also includes a lifting ring 16, which is installed at one end of the central column 1. The design of the lifting ring 16 makes the hole inspector more convenient to lift and transport. The hole inspector can be lifted by the lifting ring 16, avoiding damage or deformation that may be caused by direct contact with the hole inspector body. This not only improves the transportation efficiency of the hole inspector, but also reduces the risk of damage to the hole inspector due to improper handling.

[0059] like Figure 1 As shown, this embodiment also includes a guide member 17, which is installed at the end of the central column 1 away from the lifting ring 16. By setting the guide member 17, a good guiding effect can be achieved, allowing the borehole inspector to enter the pile hole more smoothly, reducing the obstruction caused by irregular or tilted hole openings, which helps to improve the entry efficiency of the borehole inspector and ensures that it can accurately reach the predetermined position.

[0060] In this preferred embodiment, the guide member 17 is tapered so that the hole detector is tapered, thereby enabling the hole detector to smoothly enter the pile hole.

[0061] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
