[0001] The invention belongs to the technical field of bridge detection, and in particular relates to a bridge durability detection device. Background Art

[0002] With the development of economy and society, the construction of cross-sea bridges is in the ascendant. As an important part of the transportation network, the safety performance of a large number of cross-sea bridges cannot be ignored. However, various salt ions in seawater, seawater immersion, wind and waves, tidal factors, etc. will have a great destructive effect on concrete, reduce the service life of the bridge, and affect the durability of the bridge. Therefore, there is a need for a device that can detect the durability of the bridge in the marine environment, so that it can be detected in time when the bridge is seriously damaged. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a bridge durability detection device to solve the problem of difficulty in detecting the durability performance of a bridge in a marine environment.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A bridge durability detection device comprises a cylindrical support body, a plurality of first adsorption devices are arranged on the top of the support body, an annular groove is opened on the circumferential side of the support body, an annular mounting seat is rotatably connected in the annular groove, and a power device for driving the mounting seat to rotate is arranged on the support body; a horizontally arranged guide rail is fixed on the side wall of the mounting seat, a first connecting seat is slidably connected to the guide rail, a second connecting seat is rotatably connected to the top end of the first connecting seat, a detector and a second adsorption device are arranged on the top of the second connecting seat, and a rotating device for driving the first connecting seat to rotate is arranged on the second connecting seat.

[0006] In this solution, the first adsorption device, the second adsorption device, the power device, and the rotating device are all opened and closed by wireless remote control; the supporting body is adsorbed on the bottom of the bridge beam by the first adsorption device, and the mounting seat is driven to rotate by the power device, and the mounting seat drives the first connecting seat and the second connecting seat to rotate synchronously through the guide rail, and the bottom of the beam is detected by the detector on the top of the second connecting seat; when the detector rotates one circle, the position of the first connecting seat can be adjusted to realize all-round detection of the bottom of the beam in the circular area, and the degree of damage to the bottom of the beam can be detected as much as possible, so as to achieve the purpose of detecting the durability of the bridge; when the circular area After the inspection is completed, the second connecting seat is adsorbed to the bottom of the bridge beam through the second adsorption device, and the first adsorption device is removed. The first connecting seat is driven to rotate by the rotating device, and the first connecting seat drives the guide rail, the mounting seat and the supporting body to rotate. When the supporting body rotates to the center of the next circular area, the supporting body is adsorbed to the bottom of the beam again by the first adsorption device, and the second adsorption device is released for inspection. The comprehensive inspection of the bottom of the beam can be completed without manually adjusting the position of the inspection device, which solves the problem of inspection personnel being close to the bottom of the beam for a long time in the marine environment, and greatly improves the inspection efficiency of bridge durability.

[0007] The second gear wheel is connected with the gear train of the said first and second gears and is connected with the gear train of the said first and second gears respectively.

[0008] In this solution, the electric push rod also adopts wireless remote control to open and close; when performing inspection, the first connecting seat and the second connecting seat are fitted together, and the limit blocks and limit grooves on the circumferential side of the annular plate cooperate to make the first connecting seat and the second connecting seat form a whole, and the current transmission gear is only engaged with the bottom of the second tooth portion; at this time, the transmission gear is driven to rotate by the driving motor, and the first connecting seat and the second connecting seat are driven to move on the guide rail through the engagement of the transmission gear and the second tooth plate, thereby adjusting the position of the detector to ensure that the detector can fully detect the bottom of the beam in the current circular area.

[0009] When position adjustment is required, the second connecting seat is pushed upward by the electric push rod until the second adsorption device is attached to the bottom of the beam body, and the second connecting seat is adsorbed to the bottom of the beam body by the second adsorption device. When the second connecting seat moves, the annular plate and the support shaft are driven to move synchronously, and the annular plate drives the limit block to disengage from the limit groove, so that the first connecting seat can rotate relative to the second connecting seat; and the support shaft drives the driving motor and the driving gear to move upward, so that the driving gear is engaged with the first tooth plate and the second tooth plate at the same time. At this time, when the driving motor drives the driving gear to rotate, the driving gear drives the guide rail and the first connecting seat to rotate through the first tooth plate and the second tooth plate. When the guide rail is used to drive the support body and the mounting seat to rotate to the center of the next circular area, the support body is adsorbed to the bottom of the beam body by the first adsorption device again, and the position adjustment of the device is completed. The entire operation process is infinitely remotely controlled throughout, without the need for manual assistance.

[0010] Furthermore, coaxial slide grooves are provided on both side walls at the bottom of the annular connecting groove, and the slide grooves are both annular. Arc blocks extending into the corresponding slide grooves are fixed on both sides of the electric push rod. Arc-shaped installation grooves are provided at the upper and lower ends of the arc blocks, and balls are placed in the installation grooves. A connecting frame is fixed between adjacent electric push rods.

[0011] The coordination between the arc block and the slide groove is utilized to enhance the connection stability between the electric push rod and the first connecting seat; at the same time, the friction between the arc block and the slide groove is reduced by using the ball bearing, so that when the first connecting seat rotates relative to the second connecting seat, the electric push rod can slide more easily in the annular connecting groove.

[0012] Furthermore, a through slot parallel to the guide rail is formed on the first connecting seat, and the first connecting seat is slidably connected to the guide rail via the through slot.

[0013] Furthermore, a support block is fixed on the horizontal side wall of the through groove, and horizontal grooves are opened on both sides of the guide rail along the axial direction thereof, and the support block is slidably connected in the groove.

[0014] Furthermore, both the first adsorption device and the second adsorption device are electric suction cups.

[0015] Other advantages, objectives and features of the present invention will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art may be taught from the practice of the present invention. The objectives and other advantages of the present invention may be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS
