Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, and in particular, to a bridge pile foundation inspection frame. Background Technology

[0002] In bridge construction, pile foundations are a crucial component supporting the bridge structure, and their construction quality and stability directly affect the safety and service life of the entire bridge. After pile foundation construction is completed, precise testing is required to ensure that parameters such as verticality and horizontality meet design requirements. Furthermore, frequent testing is necessary during subsequent maintenance to continuously monitor the pile foundation's condition. Currently, pile foundation testing typically uses equipment such as inclinometers. However, in practice, the installation and positioning of inclinometers present numerous inconveniences. Traditional inclinometers can only measure angles in one direction, not in two vertical or horizontal directions, and the mounting frames for inclinometers cannot accommodate installations in two horizontal directions. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a bridge pile foundation testing frame.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A bridge pile foundation testing frame includes: a mounting plate with a first fitting protrusion on its front surface, a first reference fitting plate below the first fitting protrusion; first side plates on the left and right sides of the first reference fitting plate, with opposing first limiting strips on the front sides of the first side plates on the left and right sides; and a rotating seat at the bottom of the mounting plate; and a movable mounting frame, the upper end of which is rotatably mounted on the rotating seat along a front-rear horizontal axis, the movable mounting frame including a base plate, the base plate having a second fitting protrusion, a second reference fitting plate below the second fitting protrusion; and second side plates on the front and rear sides of the second fitting protrusion, with opposing second limiting strips on the second side plates on the front and rear sides.

[0006] Furthermore, the rear side of the first reference bonding plate is provided with a downwardly inclined plate that extends to connect with the mounting plate.

[0007] Furthermore, the first reference bonding plate and the inclined plate are both spaced apart in the left-right direction to form a dust collection port in the middle.

[0008] Furthermore, a reinforcing rib is connected between the bottom of the first reference bonding plate and the inclined plate and the front surface of the mounting plate.

[0009] Furthermore, the rotating seat includes a base plate, the bottom of which is provided with ear plates spaced apart front and back, and the upper end of the movable mounting frame is embedded between the two ear plates and rotatably connected to the ear plates.

[0010] Furthermore, the ear plate is provided with threaded holes, and the upper end of the movable mounting frame is provided with rotating holes on the front and rear sides. A screw is threadedly connected to the threaded hole, and the screw is provided with a rotating column that is embedded in the rotating hole.

[0011] Furthermore, the base plate is provided with mounting through holes corresponding to the movable mounting frame.

[0012] Furthermore, reinforcing plates are connected between the left and right sides of the base plate and the front surface of the mounting plate.

[0013] Furthermore, the reinforcing plate is triangular in shape and has a hollowed-out hole in the center.

[0014] Furthermore, the first fitting protrusion has a hollow hole at its center.

[0015] This utility model has the following beneficial effects:

[0016] By setting up an installation plate and a movable installation frame for mounting the first and second inclinometers respectively, the angle detection requirements in two vertical and horizontal directions can be met simultaneously. This overcomes the limitation of traditional testing frames that can only detect angles in a single direction, providing convenience for all-round testing of pile foundations, and thus enabling the detection of changes in the tilt angle of the pile foundation in two directions. The upper end of the movable installation frame is rotatably mounted on the rotating seat at the bottom of the installation plate along the front and rear horizontal axis, allowing the movable installation frame to adaptively rotate relative to the rotating seat and maintain a vertical state. The first reference bonding plate, the first side plates on both sides, and the first limiting strip provide multi-directional limiting for the first inclinometer, while the second reference bonding plate, the second side plate, and the second limiting strip provide multi-directional limiting for the second inclinometer. This effectively prevents the instruments from shifting or shaking during the measurement process, ensuring the accuracy and reliability of the measurement results.

[0033] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a bridge pile foundation testing frame, comprising a mounting plate 100 and a movable mounting frame 200.

[0034] The front surface of the mounting plate 100 is provided with a raised first fitting protrusion 110, which allows the rear side of the first inclinometer 101 to abut against it, thus keeping the bottom rear side of the first inclinometer 101 away from the corner where the first reference fitting plate 120 connects to the mounting plate 100, preventing impurities at the corner from affecting the installation accuracy of the first inclinometer 101. The mounting plate 100 may be provided with mounting holes, allowing the mounting plate 100 to be fixed to the pile foundation with fasteners. The mounting plate 100 can be permanently fixed to the pile foundation, thereby allowing the angle change and trend of the pile foundation to be known based on the changes in angle measured by the inclinometer each time.

[0035] The mounting plate 100 has a first reference bonding plate 120 below the first bonding protrusion 110. The upper surface of the first reference bonding plate 120 serves as the mounting reference surface and is used for the bottom of the first inclinometer 101 to be bonded. The mounting plate 100 has first side plates 130 on the left and right sides of the first reference bonding plate 120. The first side plates 130 on the left and right sides limit the left and right sides of the first inclinometer 101. The front of the first side plates 130 on the left and right sides has first limiting strips 131 extending in opposite directions. That is, the front of the left side plate 130 has a first limiting strip 131 extending to the right, and the front of the right side plate 130 has a first limiting strip 131 extending to the left. The first limiting strips 131 are used to limit the forward movement of the first inclinometer 101 to prevent the first inclinometer 101 from falling and being damaged. The bottom of the mounting plate 100 has a rotating seat 140.

[0036] The upper end of the movable mounting frame 200 is rotatably mounted on the rotating seat 140 along the front and rear horizontal axis. The movable mounting frame 200 includes a base plate 210. The base plate 210 is provided with a raised second fitting protrusion 220. The second fitting protrusion 220 can be used to abut the rear side of the second inclinometer 102, so that the bottom rear side of the second inclinometer 102 is far away from the corner where the base plate 210 and the second reference bonding plate 230 are connected, thus avoiding impurities at the corner from affecting the installation accuracy of the second inclinometer 102. The substrate 210 has a second reference bonding plate 230 below the second bonding protrusion 220; the upper surface of the second reference bonding plate 230 serves as the mounting reference surface for the second inclinometer 102. The substrate 210 has second side plates 240 on both the front and rear sides of the second bonding protrusion 220, thereby limiting the movement of the second inclinometer 102 on both sides. The second side plates 240 on both the front and rear sides have opposing second limiting strips 241, that is, the right side of the front second side plate 240 has a rearwardly extending second limiting strip 241, and the right side of the rear second side plate 240 has a forwardly extending second limiting strip 241, thereby limiting the movement of the second inclinometer 102 on both the left and right sides. It can be understood that the first inclinometer 101 and the second inclinometer 102 are placed perpendicularly, referring to... Figure 2 The first inclinometer 101 faces forward, and the second inclinometer 102 faces right.

[0037] A preferred embodiment of this utility model provides a bridge pile foundation testing frame. By setting an mounting plate 100 and a movable mounting frame 200 for mounting a first inclinometer 101 and a second inclinometer 102, it can simultaneously meet the angle detection requirements in two vertical and horizontal directions, solving the limitation of traditional testing frames that can only detect angles in a single direction. This provides convenience for all-round testing of pile foundations, thereby detecting changes in the tilt angle of the pile foundation in two directions. The upper end of the movable mounting frame 200 is rotatably mounted on a rotating seat 140 at the bottom of the mounting plate 100 along the front and rear horizontal axis. Thus, the movable mounting frame 200 can adaptively rotate relative to the rotating seat 140 to maintain a vertical state. That is, when the mounting plate 100 is tilted in the left and right horizontal directions, the movable mounting frame 200, due to its ability to rotate along the front and rear horizontal axis and its own gravity, will not tilt with the mounting plate 100 in the left and right horizontal directions, but will adaptively rotate to a vertical state, that is, remain perpendicular to the left and right horizontal directions. The first reference bonding plate 120, the first side plates 130 on both sides, and the first limiting strip 131 provide multi-directional limiting for the first inclinometer. The second reference bonding plate 230, the second side plate 240, and the second limiting strip 241 provide multi-directional limiting for the second inclinometer. This effectively prevents the instrument from shifting or shaking during the measurement process, ensuring the accuracy and reliability of the measurement results.

[0038] Understandably, the first inclinometer 101 and the second inclinometer 102 are typically fitted with magnets on their bottom surfaces to magnetically attach to the metal structure. The mounting plate 100 and the movable mounting frame 200 can be made of a magnetically attachable metal material, such as stainless steel. The first inclinometer 101 and the second inclinometer 102 can be any inclinometer currently available on the market, such as the digital inclinometers from Delixi Electric or Shengtaixin.

[0039] Reference Figure 4 and Figure 5 In some embodiments of this utility model, the rear side of the first reference bonding plate 120 is provided with a downwardly inclined plate 121 that extends to connect with the mounting plate 100. This ensures that during cleaning, impurities at the corners will not remain on the first reference bonding plate 120, or at least will not be on the same horizontal plane as the first reference bonding plate 120. When cleaning impurities on the first reference bonding plate 120, the impurities will slide down along the inclined plate 121, thus facilitating quick and easy cleaning of impurities on the first reference bonding plate 120. Furthermore, the connection between the first reference bonding plate 120 and the mounting plate 100 is achieved through the inclined plate 121, which effectively prevents impurities from remaining at the corners of the first reference bonding plate 120 and the mounting plate 100.

[0040] Reference Figure 4 and Figure 5 In some embodiments of this utility model, the first reference bonding plate 120 and the inclined plate 121 are both spaced apart in the left and right direction to form a dust collection port 122 in the middle, so that impurities can fall off quickly during cleaning and achieve rapid cleaning.

[0041] Reference Figure 4 and Figure 5 In some embodiments of this utility model, a reinforcing rib 123 is connected between the bottom of the first reference bonding plate 120 and the inclined plate 121 and the front surface of the mounting plate 100, thereby improving the structural strength of the first reference bonding plate 120, reducing deformation, and avoiding additional errors in angle measurement.

[0042] Reference Figures 3 to 5 In some embodiments of this utility model, the rotating seat 140 includes a base plate 141, and the bottom of the base plate 141 is provided with ear plates 142 spaced apart front and back. The upper end of the movable mounting frame 200 is embedded between the two ear plates 142 and rotatably connected to the ear plates 142, thereby realizing the rotatable mounting of the movable mounting frame 200 and the mounting plate 100.

[0043] Reference Figure 3 and Figure 4In a further embodiment of this utility model, the ear plate 142 is provided with a threaded hole 143, and the upper end of the movable mounting frame 200 is provided with a rotating hole 250 on the front and rear sides. A screw 300 is threadedly connected to the threaded hole 143, and the screw 300 is provided with a rotating post 310 embedded in the rotating hole 250. The diameter of the rotating post 310 is smaller than that of the threaded hole 143 and the screw 300. A screw head is provided at the end of the screw 300 away from the rotating post 310, and the diameter of the screw head is larger than that of the screw 300. The movable mounting frame 200 can rotate along the rotating post 310. It can be understood that the rotating hole 250 and the rotating post 310 are clearance fit, thereby enabling rotational movement and avoiding interference fit that would cause jamming and prevent rotation. Of course, lubricating oil can also be applied to the connection between the two during maintenance to keep the rotational movement smooth.

[0044] Reference Figure 3 and Figure 4 In a further embodiment of this utility model, the base plate 141 is provided with a mounting through hole 145 corresponding to the movable mounting frame 200, so that when installing and disassembling the second inclinometer 102, the second inclinometer 102 can pass through the mounting through hole 145, avoiding structural interference, and the second inclinometer 102 can be installed and disassembled without the need to completely disassemble the movable mounting frame 200.

[0045] Reference Figure 3 and Figure 4 In a further embodiment of this utility model, a reinforcing plate 150 is connected between the left and right sides of the base plate 141 and the front surface of the mounting plate 100, thereby reinforcing and supporting the base plate 141 and preventing it from being easily deformed due to overhang.

[0046] Reference Figure 3 and Figure 4 In a further embodiment of this utility model, the reinforcing plate 150 is triangular and has a hollow hole 151 in the center, thereby reducing the structural weight and the accumulation of impurities.

[0047] Reference Figure 3 and Figure 4 In a further embodiment of this utility model, the first fitting protrusion 110 is provided with a hollow hole 111 in the center, thereby reducing the overall weight. Similarly, the second fitting protrusion 220 is also provided with a hollow hole. In addition, in order to achieve structural balance, a counterweight 260 is connected to the right side of the second side plate 240, so that the center of gravity of the movable mounting frame 200 and the center of gravity of the second inclinometer are on the same vertical axis.

[0048] like Figure 4 As shown, in a specific embodiment of this utility model, the base plate 141 is provided with an avoidance hole 144 at the ash discharge port 122.

[0049] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
