Description

Technical Field

[0001] This utility model relates to the field of bridge inspection equipment technology, and in particular to a detachable bridge pier defect detection device. Background Technology

[0002] Bridge bearings, as elastic supports located atop the piers and supporting the box girder, occupy a unique position, sandwiched between the pier and the box girder, creating a relatively confined space. During the construction and long-term use of concrete bridges, due to the combined effects of natural forces and human factors, serious problems such as concrete spalling and cracking may occur. These problems undoubtedly pose a significant threat to the safety and durability of the bridge. Therefore, regular inspection of the bridge pier surfaces has become a necessary measure to ensure the healthy operation of the bridge.

[0003] Currently, the inspection method for bridge pier bearings is to use a robotic arm to drive a camera mechanism for impact testing. However, since the inspection wall is usually quite bulky and has limited freedom of movement, it is quite difficult for the robotic arm to reach the bearing position. What is more complicated is that since the robotic arm extends from one side of the bridge to the underside, it cannot easily go around to the other side of the bearing, which limits its ability to perform 360-degree all-round inspection of bridge bearings.

[0004] Therefore, it is necessary to provide a detachable bridge pier defect detection device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a detachable bridge pier defect detection device to solve the problem that the existing device cannot easily go around to the other side of the support, which limits its ability to perform 360-degree all-round detection of bridge supports.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A detachable bridge pier defect detection device includes: a clamping tube;

[0008] The clamping tube is equipped with clamping wheels inside, which are clamped onto the side bars of the bridge. The end of the clamping tube near the bridge deck is connected to the counterweight of the inspection vehicle. The top of the clamping tube is equipped with a mounting base, which is connected to the rotating arm via a support plate. The rotating arm has multiple sections, and each section is equipped with an adjusting motor. Adjacent rotating arms are connected via shaft holes. The bottom surface of the rotating arm is connected to a connecting plate, and the bottom of the connecting plate is connected to the top surface of the base plate. Together, they form an L-shaped structure. The base plate extends towards the bottom of the bridge body, and its right side is connected to the support part of the electric telescopic rod, while its left side is connected to the drive mechanism. The front end of the drive mechanism is equipped with an inspection mechanism.

[0009] In one embodiment, the base plate has a through groove inside, which is opened opposite to the electric telescopic rod and the drive mechanism, and the electric telescopic rod passes through the through groove and is connected to the drive mechanism.

[0010] In one embodiment, a diagonal tie rod is installed on the side of the connecting plate facing the top surface of the base plate, and the other end of the diagonal tie rod is bolted to the top left side of the base plate.

[0011] In one embodiment, the driving mechanism comprises a support rod, a housing, a drive motor, an active gear, an opening, and a rack. The housing is mounted on the end of the support rod facing the bridge surface. The housing is arc-shaped with an opening on its side. A slot is formed on the arc surface of the housing facing the support rod. The drive motor is mounted at the bottom of the connection between the support rod and the housing. The drive motor is connected to the active gear located on the top surface of the support rod. Part of the tooth surface of the active gear extends into the housing through the slot. A rack is slidably connected to the housing. The rack has a semi-circular structure with an inner diameter larger than the diameter of the bridge bearing. The tooth surface of the rack meshes with the portion of the active gear located inside the housing. Detection mechanisms are mounted on the inner walls of both ends of the rack.

[0012] In one embodiment, the detection mechanism comprises a fixed rod, an electrical control box, a camera, a searchlight, a light shield, a protective plate, a mounting rod, and a pressure sensor. The right end of the fixed rod is connected to a rack and pinion. The electrical control box is mounted on the outer side of the fixed rod, and the camera is mounted on the inner side of the fixed rod. A searchlight is mounted above the camera, and a light shield is mounted between the searchlight and the camera. A protective plate is hinged to the extended end of the fixed rod, and a torsion spring is mounted at the connection between the protective plate and the fixed rod. The protective plate is bent, and the extension length of its end is greater than the length of the camera. A mounting rod is mounted between the inner side of the protective plate and the inner wall of the fixed rod. The mounting rod is also bent, and a pressure sensor is mounted on its side facing the protective plate. The pressure sensor, camera, and searchlight are all electrically connected to the electrical control box.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model pushes the support rod toward the bridge support by an electric telescopic rod until the bridge support is inside the rack rod. The drive motor drives the active gear to rotate, which in turn drives the rack rod meshing with it to rotate, and drives the detection mechanism to rotate around the bridge support to perform image detection on the outer peripheral wall of the bridge support.

[0015] (2) This utility model uses a camera to perform image detection on the bridge support. The data is transmitted through the electrical control box. The camera is assisted by a searchlight to perform the detection work. If the position of the support rod is offset, in order to protect the camera, the protective plate first contacts the surface of the bridge support and squeezes the pressure sensor to issue an alarm. After receiving the alarm, the staff can readjust the movement path to avoid damaging the camera. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] like Figures 1-2 As shown, the present invention provides a detachable bridge pier defect detection device, comprising: a clamping tube 1, a mounting base 2, a rotating arm 3, a connecting plate 4, a base plate 5, an electric telescopic rod 6, a drive mechanism 7, and a detection mechanism 8.

[0023] like Figures 1-2As shown, a clamping wheel 11 is installed inside the clamping tube 1. The clamping wheel 11 is clamped at the side bar of the bridge. The end of the clamping tube 1 near the bridge deck is connected to the counterweight of the inspection vehicle. A mounting seat 2 is installed on the top of the clamping tube 1. The mounting seat 2 is connected to the rotating arm 3 through a support plate 21. The rotating arm 3 has multiple sections. Each section of the rotating arm 3 is equipped with an adjusting motor 31. Adjacent rotating arms 3 are connected through shaft holes. Different lengths of rotating arms 3 can be replaced according to the bridge body spacing. The bottom surface of the rotating arm 3 is connected to the connecting plate 4. The bottom of the connecting plate 4 is connected to the top surface of the base plate 5. The two together form an L-shaped structure. The base plate 5 extends towards the bottom surface of the bridge body. Its right side is connected to the support part of the electric telescopic rod 6, and its left side is connected to the drive mechanism 7. A detection mechanism 8 is installed inside the front end of the drive mechanism 7.

[0024] Preferably, in one embodiment, such as Figures 1-2 As shown, the base plate 5 has a through groove 51 inside. The through groove 51 is opened opposite to the electric telescopic rod 6 and the drive mechanism 7 respectively. The electric telescopic rod 6 passes through the through groove 51 and is connected to the drive mechanism 7. Through the through-hole structure, the through groove 51 can provide auxiliary support to the drive mechanism 7 and the electric telescopic rod 6, making them more stable when working.

[0025] Preferably, in one embodiment, such as Figure 2 As shown, a diagonal tie rod 52 is installed on the side of the connecting plate 4 facing the top surface of the base plate 5. The other end of the diagonal tie rod 52 is bolted to the top left side of the base plate 5. By setting the diagonal tie rod 52, an auxiliary pulling force can be effectively provided to the base plate 5 to avoid bending and deformation of the base plate 5 under long-term load.

[0026] Preferably, in one embodiment, such as Figure 3As shown, the drive mechanism 7 consists of a support rod 71, a housing 72, a drive motor 73, a drive gear 74, an opening 75, and a rack 76. The housing 72 is mounted on the end of the support rod 71 facing the bridge surface. The housing 72 is arc-shaped, with an opening 75 on its side. A slot is formed on the arc surface of the housing 72 facing the support rod 71. The drive motor 73 is mounted at the bottom of the connection between the support rod 71 and the housing 72. The drive motor 73 is connected to the drive gear 74 located on the top surface of the support rod 71. Part of the tooth surface of the drive gear 74 extends into the housing 72 through the slot. A rack rod 76 is slidably connected to the inside of the housing 72. The rack rod 76 has a semi-circular structure and its inner diameter is larger than that of the bridge support. The tooth surface of the rack rod 76 meshes with the part of the active tooth 74 located inside the housing 72. Detection mechanisms 8 are installed on the inner walls of both ends of the rack rod 76. The support rod 71 is pushed toward the bridge support by the electric telescopic rod 6 until the bridge support is located inside the rack rod 76. The drive motor 73 drives the active tooth 74 to rotate, which in turn drives the rack rod 76 to rotate, causing the detection mechanism 8 to rotate around the bridge support and perform image detection on the outer peripheral wall of the bridge support.

[0027] Preferably, in one embodiment, such as Figure 4 As shown, the detection mechanism 8 consists of a fixed rod 81, an electrical control box 82, a camera 83, a searchlight 84, a light shield 85, a protective plate 86, a mounting rod 87, and a pressure sensor 88. The right end of the fixed rod 81 is connected to a rack 76. The electrical control box 82 is mounted on the outer side of the fixed rod 81, and the camera 83 is mounted on the inner side of the fixed rod 81. A searchlight 84 is mounted above the camera 83, and a light shield 85 is installed between the searchlight 84 and the camera 83. A protective plate 86 is hinged to the extended end of the fixed rod 81. A torsion spring is installed at the connection between the protective plate 86 and the fixed rod 81. The protective plate 86 is bent, and its extended length at the end is greater than the length of the camera 83. An installation rod 87 is installed between the inner side of the protective plate 86 and the inner wall of the fixing rod 81. The installation rod 87 is also bent, and a pressure sensor 88 is installed on its side facing the protective plate 86. The pressure sensor 88, camera 83, and searchlight 84 are all electrically connected to the electrical control box 82. During operation, the camera 83 performs image detection on the bridge support, and the data is transmitted through the electrical control box 82. The searchlight 84 assists the camera 83 in its detection work. If the support rod 71 is displaced, in order to protect the camera 83, the protective plate 86 first contacts the surface of the bridge support and squeezes the pressure sensor 88 to issue an alarm. Upon receiving the alarm, the staff readjusts the movement path to avoid damaging the camera 83.

[0028] Working principle of this utility model:

[0029] During operation, the electric telescopic rod 6 pushes the support rod 71 toward the bridge bearing until the bridge bearing is inside the rack rod 76. The drive motor 73 drives the active gear 74 to rotate, which in turn drives the rack rod 76 to rotate, causing the detection mechanism 8 to rotate around the bridge bearing and perform image detection on the outer wall of the bridge bearing. The image detection of the bridge bearing is performed by the camera 83, and the data is transmitted through the electrical control box 82. The searchlight 84 assists the camera 83 in its detection work. If the support rod 71 is misaligned, in order to protect the camera 83, the protective plate 86 first contacts the surface of the bridge bearing and squeezes the pressure sensor 88 to issue an alarm. After receiving the alarm, the staff readjusts the movement path to avoid damaging the camera 83.

[0030] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
