Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, and in particular to a testing device for pre-embedded sleeves. Background Technology

[0002] The core of modular integrated building is to disassemble a building into standardized modules, complete more than 90% of the processes in the factory, and then transport them to the site for rapid assembly. This approach achieves both "factory prefabrication and on-site hoisting" in parallel to shorten the construction period, and also aligns with green building requirements through standardized factory production, making it the mainstream direction of building industrialization. Vertical prefabricated wall panels are the core enclosure and load-bearing components of modular integrated buildings. Adjacent vertical prefabricated wall panels are connected by multiple sets of connecting components. These components consist of two embedded sleeves, each pre-embedded in one of the adjacent vertical prefabricated wall panels, and a threaded rod connecting the two sleeves. The embedded sleeves extend from the opposite sides of the two adjacent vertical prefabricated wall panels, and their inner walls are threaded. To ensure smooth assembly and safe load transfer, the pre-embedded sleeve must meet two core requirements: First, it must be strictly perpendicular to the surface of the vertical precast wall panel to ensure that the load is transferred along the axis of the pre-embedded sleeve, avoiding radial force that could cause wear on the pre-embedded sleeve and cracking of the vertical precast wall panel. Second, the pre-embedded sleeve must be precisely positioned in the preset location to ensure that the axes of the two pre-embedded sleeves in the connecting components of two adjacent vertical precast wall panels are aligned, allowing for smooth connection of the threaded rods. If the pre-embedded sleeve has a verticality deviation or positional offset, it will cause misalignment during splicing and difficulties in connecting the threaded rods.

[0003] In existing technologies, the inspection of embedded sleeves is generally carried out by manual single-point measurement using tools such as handheld right-angle rulers and measuring tapes, which has obvious drawbacks: extremely low efficiency, difficult to adapt to the pace of mass production in factories, and slowing down the progress of vertical prefabricated wall panel delivery and on-site assembly; the accuracy is greatly affected by operating experience and subjective judgment, and is prone to omissions; and it is impossible to simultaneously detect verticality and positional deviation, making it difficult to meet the requirements of modular integrated buildings for construction accuracy and efficiency.

[0004] Therefore, there is an urgent need for a detection device for pre-embedded sleeves to detect the verticality and position of pre-embedded sleeves in batches. Utility Model Content

[0034] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably with other directional terms. Figure 1 and Figure 2 The orientation is used as a reference.

[0035] Example 1:

[0036] Reference Figures 1 to 6 This embodiment proposes a detection device for embedded sleeves, used to detect the verticality and position of embedded sleeves in connecting components. Specifically, the detection device for embedded sleeves in this embodiment includes a detection component 1, a first vertical frame 2, a second vertical frame 3, a third vertical frame 4, and a base assembly 5, as detailed below.

[0037] In this embodiment, the first vertical frame 2, the second vertical frame 3, and the third vertical frame 4 are arranged sequentially at intervals along the horizontal direction, and all three extend vertically to form a support system that can be adjusted collaboratively. The first vertical frame 2 and the base assembly 5 employ a sliding fit structure, allowing the first vertical frame 2 to move smoothly relative to the base assembly 5 in the front-to-back direction. The second vertical frame 3 and the first vertical frame 2 are also provided with a sliding fit structure, ensuring that the second vertical frame 3 can move precisely relative to the first vertical frame 2 in the up-down direction. The third vertical frame 4 and the second vertical frame 3 also employ a sliding fit structure, enabling the third vertical frame 4 to move flexibly relative to the second vertical frame 3 in the left-to-right direction. Simultaneously, it is necessary to ensure that the overall state of the third vertical frame 4 remains parallel to the outer surface of the vertical precast wall panel, thus establishing a unified benchmark for subsequent testing.

[0038] Several testing components 1 are installed on the front side of the third vertical frame 4. The front side of the third vertical frame 4 corresponds to the embedded sleeve to be tested. The testing components 1 and the third vertical frame 4 are detachably connected to each other, so as to replace or maintain them according to the actual preset specifications of the embedded sleeves and ensure testing compatibility. The number and arrangement of the testing components 1 must strictly match the preset positions of all embedded sleeves on the vertical precast wall panel. That is, each testing component 1 can correspond to the preset position of an embedded sleeve in the testing state, thereby realizing the synchronous testing of all embedded sleeves on the vertical precast wall panel. The testing of the embedded sleeve is done by inserting the testing component 1 into the embedded sleeve. The testing components 1 are set according to the preset positions of the embedded sleeves on the front side of the third vertical frame 4. Therefore, whether the testing component 1 can be inserted into the embedded sleeve proves whether there are any problems with the position and verticality of the embedded sleeve.

[0039] Furthermore, for each embedded sleeve on a different vertical precast wall panel, the detection element 1 on the third vertical frame 4 must correspond one-to-one. Therefore, while the third vertical frame 4 and the second vertical frame 3 are slidably connected, they are also detachably connected. By replacing different third vertical frames 4, and ensuring that the detection element 1 on each third vertical frame 4 corresponds one-to-one with the embedded sleeve on a different vertical precast wall panel, the detection of embedded sleeves on different vertical precast wall panels can be achieved. Alternatively, the detection device for embedded sleeves can have multiple models, each model targeting a different vertical precast wall panel. That is, the third vertical frame 4 in the detection device for each model of embedded sleeve is different, and the detection element 1 installed on the third vertical frame 4 corresponds one-to-one with the embedded sleeve on its corresponding vertical precast wall panel. This also enables the detection of embedded sleeves on different vertical precast wall panels.

[0040] During the actual testing process, the base assembly 5 is moved to face the outer side of the vertical precast wall panel, ensuring that the third vertical frame 4 is parallel to the outer side of the vertical precast wall panel to be tested, thus avoiding the influence of reference deviation on the test results. Subsequently, the relative positions of the first vertical frame 2, the second vertical frame 3, and the third vertical frame 4 are coordinated to drive the movement of the testing element 1. That is, by using the back-and-forth sliding of the first vertical frame 2 relative to the base assembly 5, the back-and-forth positions of the first vertical frame 2, the second vertical frame 3, and the third vertical frame 4 are simultaneously adjusted, as well as the distance of the testing element 1 in the back-and-forth direction, so that the testing element 1 gradually approaches the opening end of the pre-embedded sleeve. By using the up-and-down sliding of the second vertical frame 3 relative to the first vertical frame 2, the up-and-down positions of the second vertical frame 3 and the third vertical frame 4 are simultaneously adjusted, as well as the position of the testing element 1 in the up-and-down direction, ensuring that each testing element 1 is aligned with the corresponding pre-embedded sleeve's preset vertical position. By sliding the third vertical frame 4 relative to the second vertical frame 3 left and right, the left and right positions of the third vertical frame 4 are adjusted, and the positions of the detection elements 1 in the left and right directions are also adjusted, so that each detection element 1 is precisely aligned with the horizontal preset position of the corresponding pre-embedded sleeve. Through the above multi-directional adjustments, the forward movement of the first vertical frame 2 relative to the base assembly 5 is finally adjusted again, so that all detection elements 1 can be synchronously inserted into the corresponding pre-embedded sleeve, completing the synchronous detection of the position and verticality of the pre-embedded sleeve, proving that the position and verticality of the corresponding pre-embedded sleeve are not problematic. If any detection element 1 cannot be inserted into the pre-embedded sleeve, it proves that the position or verticality of the pre-embedded sleeve at this location is problematic and needs to be repaired.

[0041] In summary, compared to existing technologies, the sliding adjustment in the front-back, up-down, and left-right directions is achieved through the first vertical frame 2, the second vertical frame 3, and the third vertical frame 4, respectively. This allows for flexible adaptation to different wall positions and the distribution of embedded sleeves, meeting the needs of diverse testing scenarios. The third vertical frame 4 is parallel to the outer surface of the wall, and the testing piece 1 is perpendicular to the third vertical frame 4 and corresponds one-to-one with the embedded sleeve. This ensures a unified testing benchmark based on the wall. Through the cooperation of the frames, multiple testing pieces 1 can be simultaneously inserted into the corresponding embedded sleeve ends, enabling batch testing. This effectively solves the problems of time-consuming, labor-intensive, and prone to omissions in manual testing, significantly improving testing efficiency and accuracy, ensuring the installation quality of embedded sleeves, reducing safety hazards caused by installation deviations, and meeting the high-efficiency testing needs of industrial production.

[0042] Furthermore, the first vertical frame 2 is composed of a first rectangular frame 21, a connecting frame 22, multiple first sliders 23, and at least two first slide rails 24. The first slide rails 24 extend in the front-to-back direction and are fixedly mounted on the top of the base assembly 5, providing a stable support foundation for the subsequent sliding structure. At least two first sliders 23 are slidably fitted onto each first slide rail 24, and the first sliders 23 are spaced apart along the length of the first slide rail 24. Simultaneously, the first sliders 23 can stop at both ends of the first slide rail 24 to limit the sliding stroke of the first sliders 23 along the first slide rail 24 and prevent them from detaching during sliding.

[0043] The lower surface of the connecting frame 22 is fixedly connected to the upper surface of the first slider 23, and the connecting frame 22 is fixedly connected to the lower end of the first rectangular frame 21, so that the first rectangular frame 21 and the connecting frame 22 form an integrated structure. This integrated structure achieves a sliding connection with the base assembly 5 through the sliding engagement of multiple first sliders 23 and at least two first slide rails 24, thereby enabling the first rectangular frame 21 to move smoothly relative to the base assembly 5 in the front-back direction along with the connecting frame 22.

[0044] The second vertical frame 3 is slidably connected to the front side of the first rectangular frame 21. Through this sliding connection, the second vertical frame 3 is provided with structural support for the vertical movement of the second vertical frame 3 relative to the first rectangular frame 21, so as to adapt to the subsequent position adjustment requirements of the test piece 1 in the vertical direction.

[0045] Furthermore, the first vertical frame 2 includes a first rectangular frame 21, a connecting frame 22, a plurality of first sliders 23 and at least two first slide rails 24.

[0046] The first slide rail 24 extends in the front-to-back direction and is fixedly mounted to the upper part of the base assembly 5, providing a stable support foundation for the subsequent sliding structure. At least two first sliders 23 are slidably fitted onto each first slide rail 24, with the first sliders 23 spaced apart along the length of the first slide rail 24. Simultaneously, the first sliders 23 can stop at both ends of the first slide rail 24, limiting the sliding stroke of the first sliders 23 and preventing them from detaching from the first slide rail 24 during sliding.

[0047] The connecting frame 22 adopts a triangular prism structure design. The lower surface of the connecting frame 22 is fixedly connected to the upper surface of the first slider 23, and the upper end of the connecting frame 22 is fixedly connected to the lower end of the first rectangular frame 21, so that the connecting frame 22, the first slider 23, and the first rectangular frame 21 form an integrated connection structure. Based on this integrated structure, the first rectangular frame 21 and the connecting frame 22 can move smoothly and synchronously relative to the base assembly 5 in the front-back direction through the sliding cooperation of multiple first sliders 23 and at least two first slide rails 24, ensuring the structural stability during the overall sliding process.

[0048] The second vertical frame 3 is slidably connected to the front side of the first rectangular frame 21. This sliding connection provides structural support for adjusting the position of the second vertical frame 3 relative to the first rectangular frame 21 in the vertical direction, thereby laying the foundation for subsequent coordinated adjustment of the vertical position of the test piece 1.

[0049] Furthermore, the first rectangular frame 21 includes a first rectangular frame 211, a first crossbeam 212, two first horizontal bars 213, and two first vertical bars 214. The lower end of the first rectangular frame 211 is assembled and fixed to the connecting frame 22. The combined structure formed by the two achieves a sliding connection with the base assembly 5 through the sliding engagement of multiple first sliders 23 and at least two first slide rails 24, thereby allowing it to move relative to the base assembly 5 in the front-back direction along with the connecting frame 22. The second vertical frame 3 forms a sliding engagement connection with the front side of the first rectangular frame 211, providing structural support for the vertical adjustment of the second vertical frame 3 relative to the first rectangular frame 211.

[0050] Two first horizontal bars 213 are arranged at intervals in the vertical direction and are both assembled to the rear side of the first rectangular frame 211 to enhance the structural stability of the rear side of the first rectangular frame 211. A first crossbeam 212 is assembled and fixed to the lower end of the first rectangular frame 211. Two first vertical bars 214 are arranged at intervals in the horizontal direction below the first rectangular frame 211, and the two ends of each first vertical bar 214 are respectively assembled and fixed to the first crossbeam 212 and the first rectangular frame 211. Through the cooperation of the first vertical bars 214 and the first crossbeam 212, the structural strength of the lower end of the first rectangular frame 211 is further strengthened.

[0051] In addition, the first crossbeam 212 is also assembled and fixed to the top of the connecting frame 22, thereby achieving a double stable connection between the first rectangular frame 211 and the connecting frame 22. The two first vertical rods 214 are respectively distributed on the outer side of the two end faces of the connecting frame 22, which not only avoids structural interference with the connecting frame 22, but also forms a symmetrical force distribution on the support of the first rectangular frame 211, ensuring the stress balance of the overall structure.

[0052] Furthermore, the second vertical frame 3 includes a second rectangular frame 31, a screw mechanism 32, multiple second sliders 33, and two second slide rails 34. The multiple second sliders 33 are spaced apart along the rear side of the second rectangular frame 31 in the vertical direction, and the two second slide rails 34 extend vertically and are fixed to the front side of the first rectangular frame 211. The second rectangular frame 31 achieves a sliding connection with the first rectangular frame 21 through the sliding engagement of the multiple second sliders 33 and the two second slide rails 34, allowing for smooth vertical movement.

[0053] The two ends of the screw mechanism 32 are rotatably connected to the two first crossbars 213, and both ends are limited and fixed to restrict their axial displacement. The middle part of the screw mechanism 32 is threadedly connected to the second rectangular frame 31. By driving the screw mechanism 32 to rotate, the second rectangular frame 31 can be driven to slide in the up and down direction by means of the threaded transmission, so as to realize the position adjustment of the second rectangular frame 31 relative to the first rectangular frame 21.

[0054] Furthermore, the screw mechanism 32 includes a turntable 321, a screw 322, and two bearing seats 323. The screw 322 is arranged vertically and passes through two first crossbars 213 and a second rectangular frame 31 from top to bottom, with the screw 322 and the second rectangular frame 31 forming a threaded connection. The turntable 321 is fixedly mounted on the upper end of the screw 322, providing an operating part for the rotation of the screw 322. The two bearing seats 323 are respectively sleeved on both ends of the screw 322, and each of the two bearing seats 323 is fixed to the opposite side of the two first crossbars 213, thereby achieving rotatable support and axial limiting at both ends of the screw 322.

[0055] When the drive turntable 321 rotates, the screw 322 rotates synchronously. With the help of the threaded engagement between the screw 322 and the second rectangular frame 31, the second rectangular frame 31 can slide vertically relative to the first rectangular frame 211, thereby adjusting the vertical position of the second rectangular frame 31.

[0056] Furthermore, the second rectangular frame 31 is provided with a handle protruding from the rear side of the second rectangular frame 31, and the screw 322 is threadedly connected to the handle. Thus, the rotation of the screw 322 is converted into the displacement of the second rectangular frame 31, and the handle is fixedly connected to the second rectangular frame 31 by welding, snap-fitting or riveting.

[0057] Furthermore, the second vertical frame 3 also includes multiple sliding components 35, which are sequentially fixed to the lower end face of the second rectangular frame 31 in the left-right direction. Each sliding component 35 consists of a housing 351, a fixed shaft 352, and a roller 353.

[0058] A fixed shaft 352 extends in the front-to-back direction and is fixed to one end of the housing 351. The housing 351 extends from the lower end of the second rectangular frame 31 towards the front of the second rectangular frame 31 and protrudes from the lower end face of the second rectangular frame 31. An opening is provided at the top of the housing 351. A roller 353 is rotatably fitted onto the fixed shaft 352, and the roller 353 protrudes from the upper surface of the housing 351 through the opening, forming an abutment with the lower end face of the third vertical frame 4. The sliding assembly 35 can support the third vertical frame 4 and, in accordance with the movement requirements of the third vertical frame 4, allows the third vertical frame 4 to slide smoothly in the left-to-right direction.

[0059] Furthermore, the third vertical frame 4 is composed of a third rectangular frame 41 and multiple clamping members 42. The multiple clamping members 42 are respectively distributed at the upper and lower ends of the third rectangular frame 41 and the second rectangular frame 31, forming a connection structure at corresponding positions. Each clamping member 42 includes a first long side extending in the front-back direction, and a second long side and a third long side perpendicular to the first long side. The second long side, the first long side, and the third long side are sequentially fixedly connected, together forming a U-shaped structure.

[0060] During assembly, the second long side is fitted and fixedly connected to the second rectangular frame 31, and the third long side is fitted to the third rectangular frame 41. Through the clamping and engagement of this U-shaped structure, an anti-detachment connection is formed between the second rectangular frame 31 and the third rectangular frame 41, ensuring that the two will not separate during relative sliding, while not affecting the movement of the third rectangular frame 41 in the left and right directions.

[0061] Furthermore, the testing component 1 is a screw extending in the front-to-back direction, the diameter of which is adapted to the pre-embedded sleeve. During the testing process, the screw can extend into the pre-embedded sleeve, and the verticality and position of the pre-embedded sleeve can be detected by whether it can extend smoothly and its state after extension. Moreover, the third vertical frame 4 has a through hole for installing the testing component 1. The testing component 1 passes through the through hole in the third vertical frame 4, and two washers and two nuts are respectively fitted on both sides of the through hole. The nuts are threadedly connected to the screw and squeeze the two washers, so that the two washers are clamped to the third vertical frame 4, thereby the screw can be detachably connected to the third vertical frame 4.

[0062] Furthermore, the base assembly 5 includes a rectangular base frame 51, four support legs 52, four casters 53, and a pull rod 54. The four casters 53 are respectively mounted at the four corners of the rectangular base frame 51, facilitating the movement of the entire device. A first slide rail 24 is fixedly connected to the upper surface of the rectangular base frame 51, forming a connection base with the first vertical frame 2. The four support legs 52 are arranged adjacent to the four casters 53 and are movably connected to the rectangular base frame 51 in the vertical direction. By adjusting the extension length of the four support legs 52, the rectangular base frame 51 can be kept in a horizontal position, ensuring the reference stability during the testing process. The pull rod 54 is rotatably connected to one end of the rectangular base frame 51, facilitating pushing or pulling the entire device and improving operational convenience.

[0063] Furthermore, the outrigger 52 is composed of a support plate 521, a threaded rod 522, and two nuts 523. The support plate 521, the threaded rod 522, and the two nuts 523 achieve support and position locking functions through a specific fit. The specific structure is as follows:

[0064] The threaded rod 522 is fixed above the support plate 521 and extends vertically through the rectangular base frame 51. Two nuts 523 are threadedly connected to the threaded rod 522. One nut 523 is located on the upper side of the rectangular base frame 51, and the other nut 523 is located on the lower side of the rectangular base frame 51. The cooperation of the two nuts 523 locks the position of the threaded rod 522 relative to the rectangular base frame 51, thereby fixing the support height of the support leg 52 and providing a structural basis for the horizontal adjustment of the rectangular base frame 51.
