Description

Technical Field

[0001] This application belongs to the technical field of bridge construction, and more specifically, relates to a rapid acceptance device for bridge paving stones. Background Technology

[0002] Padstones are concrete components used in bridge engineering, placed at the connection points between abutments, pier tops, and supports. Before the beams are erected, the construction unit's technical personnel must inspect the pre-reserved anchor bolt holes in advance. The pre-reserved holes are grouped into sets of four, with the four pre-reserved holes in the same group arranged in a rectangular pattern.

[0003] The existing acceptance device for reserved holes in the foundation stone includes a rectangular frame and a cross fixed inside the rectangular frame. The size of the rectangular frame is adapted to the distribution and size of the reserved holes. The four corners of the rectangular frame are used to coincide with the axes of the four reserved holes. The cross is used to coincide with the measurement and layout center line between the four reserved holes. The measurement and layout center line is the chalk line on the top surface of the foundation stone.

[0004] When inspecting the reserved holes, first mark a cross line between the four reserved holes, then align the cross line with the marked line and visually observe whether the four corners of the rectangular frame coincide with the center of the four reserved holes. However, although this method can observe the four reserved holes at the same time, it is prone to observation errors, which can affect the construction quality. Utility Model Content

[0005] The purpose of this application is to provide a rapid acceptance device for foundation stones, so as to solve the technical problem that although the existing technology can simultaneously observe four reserved holes, it is easy to produce observation errors, which affects the construction quality.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a rapid acceptance device for foundation stones, including a rectangular frame and a cross-shaped structure disposed within the rectangular frame; the rapid acceptance device for foundation stones further includes: Four sliding bars are slidably disposed at the four corners of the rectangular frame, and the outer ends of the sliding bars are provided with top plates for contacting the inner walls of the pre-drilled holes; and Four sets of adjustment components are connected one-to-one with the four sliders. The adjustment components are used to drive the sliders to slide away from the rectangular frame. In one possible implementation, based on the above technical solutions, the sliding directions of two sliders located on the same diagonal of the rectangular frame are consistent; the sliding directions of adjacent sliders located on different diagonals of the rectangular frame are perpendicular to each other.

[0007] In one possible implementation, based on the above technical solutions, the adjustment component includes: The mounting bracket is disposed within the rectangular frame and located on one side of the sliding bar; A gear, rotatably mounted on the mounting bracket, has a handwheel located at the top of its rotating shaft; and A rack is fixed parallel to one side of the sliding bar and meshes with the gear.

[0008] In one possible implementation, based on the above technical solutions, the mounting bracket is detachably connected to the rectangular frame by bolts; the corners of the rectangular frame have openings for the sliding bar and the rack to slide out.

[0009] In one possible implementation, based on the above technical solutions, the rectangular frame has a strip-shaped hole located directly above the sliding bar; the adjustment component includes: Two mounting plates are positioned opposite each other on the rectangular frame; A screw, rotatably mounted between the two mounting plates and parallel to the sliding bar, has a handwheel coaxially mounted at one end; and The sliding block is threaded to the screw and fixed to the sliding bar after passing through the strip hole.

[0010] In one possible implementation, based on the above technical solutions, the mounting plate is detachably connected to the rectangular frame by bolts; the corners of the rectangular frame have openings for the sliding strip and the sliding block to slide out.

[0011] In one possible implementation, based on the above technical solutions, each slider has a scale line on its top surface along its sliding direction.

[0012] In one possible implementation, based on the above technical solutions, the side of the top plate that contacts the inner wall of the reserved hole is an arc-shaped surface.

[0013] In one possible implementation, based on the above technical solutions, the rectangular frame is composed of four welded steel pipes.

[0014] The beneficial effects of the rapid acceptance device for foundation stones provided in this application are as follows: Compared with the prior art, when conducting acceptance of reserved holes, this application aligns the crosshair with the crosshair line between the four reserved holes and positions the four corners of the rectangular frame directly above the four reserved holes. At this time, the four adjusting components drive the four sliding strips to slide away from the rectangular frame until the top plate contacts the inner wall of the corresponding reserved hole. Based on the sliding distance of the four sliding strips, it is possible to more intuitively determine whether there is any misalignment between the four reserved holes, thereby improving the accuracy of acceptance testing and ensuring construction quality.

[0019] It should be further noted that the accompanying drawings and embodiments of this application mainly describe the concept of this application. Based on this concept, some specific forms and arrangements of connection relationships and positional relationships may not be fully described. However, under the premise that those skilled in the art understand the concept of this application, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0023] The present application provides a rapid acceptance device for foundation stones.

[0024] like Figure 1 and Figure 2 As shown, the first embodiment of this application provides a rapid acceptance device for foundation stones, including a rectangular frame 1 and a cross 2 disposed within the rectangular frame 1; the rapid acceptance device for foundation stones also includes four sliding bars 3 and four sets of adjustment components 4.

[0025] Four sliding bars 3 are horizontally slidably arranged at the four corners of the rectangular frame 1. The outer end of the sliding bar 3 is provided with a top plate 31 for contacting the inner wall of the reserved hole. Four sets of adjustment components 4 are connected to the four sliding bars 3 one by one. The adjustment components 4 are used to drive the sliding bars 3 to slide away from the rectangular frame 1.

[0026] This embodiment provides a rapid acceptance device for foundation stones. Compared with the prior art, when inspecting reserved holes, the cross 2 is aligned with the cross line between the four reserved holes, and the four corners of the rectangular frame 1 are positioned directly above the four reserved holes. At this time, the four adjusting components 4 drive the four sliding strips 3 to slide away from the rectangular frame 1 until the top plate 31 contacts the inner wall of the corresponding reserved hole. Based on the sliding distance of the four sliding strips 3, it is possible to more intuitively determine whether there is any misalignment between the four reserved holes, thereby improving the accuracy of acceptance inspection and ensuring construction quality.

[0027] like Figures 1 to 2 As shown, this application provides a further specific implementation method based on the first implementation method as follows: Two sliders 3 located on the same diagonal of the rectangular frame 1 slide in the same direction; adjacent sliders 3 located on different diagonals of the rectangular frame 1 slide in mutually perpendicular directions.

[0028] Based on the movement distance of the sliding bar 3 on the same diagonal of the rectangular frame 1, the deviation of the reserved hole in a single direction can be directly determined. Therefore, by measuring the sliding distance of the sliding bar 3 on the two diagonals in two directions, the deviation of the reserved hole in the cross direction can be directly determined. Through more precise adaptation, the accuracy of acceptance can be further improved and errors reduced.

[0029] like Figure 2 and Figure 3 As shown, this application provides a further specific implementation method based on the first implementation method as follows: The adjustment assembly 4 includes a mounting bracket 41, a gear 42, and a rack 43; the mounting bracket 41 is set inside the rectangular frame 1 and located on one side of the sliding bar 3; the gear 42 is rotatably mounted on the mounting bracket 41, and a handwheel is provided on the top of the rotating shaft of the gear 42; the rack 43 is fixed parallel to one side of the sliding bar 3 and meshes with the gear 42.

[0030] By rotating the handwheel, the gear 42 is driven to rotate, which in turn drives the rack 43 and the sliding bar 3 to move, thereby realizing the movement of the top plate 31 within the reserved hole. The transmission method of the gear 42 and rack 43 has high precision and stability, which can ensure the accuracy of the moving distance and speed of the sliding bar 3, thereby improving the device's adjustment accuracy of the reserved hole position and size. In addition, the structure is relatively simple, easy to maintain and repair, and reduces the device's operating cost and maintenance difficulty.

[0031] like Figure 3 As shown, this application provides a further specific implementation method based on the first implementation method as follows: Mounting bracket 41 is detachably connected to rectangular frame 1 by bolts; rectangular frame 1 has openings at the corners for sliding strip 3 and rack 43 to slide out.

[0032] The detachable mounting bracket 41 design allows the device to be disassembled during transportation and storage, reducing space occupation and facilitating carrying and handling. When needed, it can be quickly reassembled, improving the device's flexibility of use.

[0033] The opening design at the end of the rectangular frame 1 allows the slider 3 and rack 43 to slide out, facilitating maintenance operations such as cleaning, lubrication, and replacement of the slider 3 and rack 43. When the slider 3 or rack 43 is worn or malfunctions, it can be easily removed for repair or replacement without disassembling and replacing the entire device, reducing maintenance costs and time.

[0034] like Figures 4 to 5 As shown, a specific implementation method provided in the second embodiment of this application is as follows: A rectangular frame 1 has a slotted hole 11 located directly above the sliding bar 3; the adjusting assembly 4 includes two mounting plates 44, a screw 45, and a sliding block 46; the two mounting plates 44 are arranged opposite each other on the rectangular frame 1; the screw 45 is rotatably disposed between the two mounting plates 44 and parallel to the sliding bar 3, and a handwheel is coaxially provided at one end of the screw 45; the sliding block 46 is threaded to the screw 45, passes through the slotted hole 11, and is fixed to the sliding bar 3.

[0035] In this embodiment, rotating the handwheel causes the screw 45 to rotate, which in turn moves the sliding block 46 and the sliding strip 3 together. The threaded drive allows for precise movement of the sliding strip 3, improving the device's accuracy in detecting the position and size of the pre-drilled hole. Furthermore, the threaded drive has better self-locking performance, maintaining the stability of the sliding strip 3 after adjustment to the appropriate position, reducing movement of the sliding strip 3 due to external factors, and further improving the accuracy of acceptance testing. The slotted hole 11 not only guides the movement of the sliding block 46 but also ensures the stability of the connection between the sliding block 46 and the sliding strip 3.

[0036] like Figures 5 to 3 As shown, this application provides a further specific implementation method based on the second implementation method as follows: Mounting plate 44 is detachably connected to rectangular frame 1 by bolts; rectangular frame 1 has openings at the corners for sliding strip 3 and sliding block 46 to slide out.

[0037] The detachable mounting plate 44 allows the device to be disassembled during transportation and storage, reducing space occupation and facilitating carrying and handling. It can also be quickly reassembled when needed, improving the device's flexibility. The openings at the ends of the rectangular frame 1 allow the sliding bar 3 and sliding block 46 to slide out, facilitating cleaning, lubrication, and replacement of the sliding bar 3 and sliding block 46.

[0038] When the slider 3 or slider 46 is worn or malfunctions, it can be easily removed for repair or replacement without disassembling and replacing the entire device, thus reducing maintenance costs and time.

[0039] like Figure 1 As shown, this application provides a further specific implementation method based on the first implementation method as follows: Each slider 3 has scale lines on its top surface along its sliding direction (not shown in the figure).

[0040] The scale lines help operators accurately understand the movement distance of the slider 3, thereby more precisely adjusting the positional relationship between the device and the reserved hole. The intuitive reference method can reduce errors in human judgment and improve the accuracy of acceptance.

[0041] like Figure 3 As shown, this application provides a further specific implementation method based on the first implementation method as follows: The side of the top plate 31 that is used to contact the inner wall of the reserved hole is an arc-shaped surface.

[0042] The curved surface can better fit the inner wall of the reserved hole, increasing the contact area between the top plate 31 and the inner wall of the reserved hole, and improving the compatibility between the device and the reserved hole. During the acceptance process, the curved surface can reduce the contact problems caused by unevenness of the inner wall of the reserved hole, ensuring that the top plate 31 can accurately reflect the position and size information of the reserved hole.

[0043] like Figure 1 As shown, this application provides a further specific implementation method based on the first implementation method as follows: The rectangular frame 1 is composed of four welded steel pipes.

[0044] Before the acceptance of the foundation stone, steel pipes of appropriate length can be selected and welded together according to the distribution and size of the reserved holes to form a rectangular frame 1 that matches the size of the reserved holes. The welding connection method gives the rectangular frame 1 good integrity and stability, and the whole has the advantages of low cost and simple manufacturing process.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
