Description

Technical Field

[0001] The present application relates to the technical field of bridges, and specifically to an auxiliary device for bridge guardrail detection. Background Art

[0002] A bridge generally refers to a structure erected over rivers, lakes, and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern rapidly developing transportation industry, a bridge is also extended to a building that is erected to cross mountain streams, poor geological conditions or meet other traffic needs to make passage more convenient. A bridge generally consists of an upper structure, a lower structure, bearings, and auxiliary structures. The upper structure is also called the bridge span structure and is the main structure for crossing obstacles; the lower structure includes abutments, piers, and foundations; the bearings are load-transfer devices provided at the supporting points of the bridge span structure and the piers or abutments; the auxiliary structures refer to approach slabs, tapered slopes, revetments, diversion works, etc.

[0003] Currently, the common detection method for the outer guardrail of a bridge is to use a bridge inspection vehicle or a ladder to enable the inspector to approach for inspection. When construction workers are constructing the bridge guardrail, there is no safe and reliable construction platform, and there are many conditions restricting the work. For example, the bridge deck of the ramp bridge in the interchange area of the expressway is restricted by road closures and the bridge inspection vehicle cannot be used; for non-separated bridges, due to the distance limitation between the two guardrails of the bridge, the bridge inspection vehicle cannot be used; when the pier height is extremely high, ladders cannot be used for detection. According to the problems encountered in the work, an auxiliary device for bridge guardrail detection can be developed to solve the problems, reduce the safety risks of inspectors, reduce the detection cost, and improve the detection efficiency.

[0004] Currently, the outer detection of the bridge guardrail is to use a bridge inspection vehicle, a ladder and other means to enable the inspector to approach for inspection. These methods are greatly restricted by the on-site conditions. Especially for non-separated bridges, due to the influence of the distance between the two guardrails of the bridge, it is very difficult to use conventional detection equipment. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present application provides an auxiliary device for bridge guardrail detection, which has the advantages of being easy to carry and measure, and solves the problems raised in the background art.

[0006] To achieve the above object, the present application provides the following technical solution: a bridge guardrail detection auxiliary device, including a bridge body, a base body is provided on the upper surface of the bridge body, two sliding members are slidably connected to the inner wall of the base body, two rollers are rotatably connected to the mutually approaching side surfaces of the two sliding members, threaded rods are rotatably connected to the mutually remote side surfaces of the two sliding members, the two threaded rods are threadedly connected to the base body, two extension plates are snap-connected to the bottom surface of the base body, a swing frame is installed on the bottom surface of the lower extension plate, a swing member is rotatably connected to the inner wall of the swing frame, a pan-tilt is rotatably connected to the bottom surface of the swing member, a camera is installed on the bottom surface of the pan-tilt, and a plurality of rotating rods are rotatably connected to the bottom surface of the base body.

[0007] Through the above solution, the base body is made of light steel, which is convenient for on-site carrying and use. The inspector can check the outside of the bridge guardrail through the camera on the bridge deck.

[0008] Further, a threaded hole is opened on the outer surface of the base body, and a mobile phone holder is threadedly connected to the inside of the threaded hole.

[0009] Through the above solution, installing the mobile phone holder facilitates the installation of the mobile phone and transmits the route collected by the camera through the wireless network.

[0010] Further, a rigid elastic member is fixedly connected to the upper surface of the base body, and a drag wheel is rotatably connected to the bottom end of the rigid elastic member.

[0011] Through the above solution, the cooperation of installing the rigid elastic member and the drag wheel can make the drag wheel closely contact the bridge body, facilitating the drag wheel to drag the base body to move during rotation.

[0012] Further, a first servo motor is installed on the outer surface of the rigid elastic member, and the output end of the first servo motor is fixedly connected to the drag wheel.

[0013] Through the above solution, installing the first servo motor can drive the drag wheel to rotate, enabling the drag wheel to move through the rigid elastic member and the body, facilitating the movement of the base body.

[0014] Further, a second servo motor is installed on the outer surface of the swing frame, and the output end of the second servo motor is fixedly connected to the swing member.

[0015] Through the above solution, installing the second servo motor can drive the swing member to swing, enabling it to adjust the angle of the camera.

[0016] Further, both of the two rollers are made of rubber material.

[0017] Through the above solution, the rollers made of rubber material can increase the friction between the rollers and the bridge body, enabling the base body to be stably installed on the bridge body.

[0018] Further, two threaded cylinders are installed on the bottom surface of the base body. Connecting rods are in threaded connection inside the two threaded cylinders. The bottom ends of the two connecting rods are fixedly connected with a support base, and a counterweight block is sleeved on the outer surfaces of the two connecting rods.

[0019] Through the above solution, installing the counterweight block can increase the dead weight of one end of the base body, avoiding the influence of the large dead weight at the camera position on the balance of the base body.

[0020] Further, both the base body and the extension plate are made of light steel.

[0021] Through the above solution, both the base body and the extension plate being made of light steel can make the whole more portable. At the same time, the extension plate is easy to disassemble, facilitating the disassembly and carrying of the whole.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

Installing the mobile phone holder 13 is convenient for installing the mobile phone and transmitting the video captured by the camera 10 through a wireless network. A rigid elastic member 14 is fixedly connected to the upper surface of the base body 2. A dragging wheel 15 is rotatably connected to the bottom end of the rigid elastic member 14. The cooperation of installing the rigid elastic member 14 and the dragging wheel 15 can make the dragging wheel 15 closely contact the bridge body 1, facilitating the dragging wheel 15 to drag the base body 2 to move during rotation. A first servo motor 16 is installed on the outer surface of the rigid elastic member 14. The output end of the first servo motor 16 is fixedly connected to the dragging wheel 15.

Then install the mobile phone holder 13 into the threaded hole 12. When conducting detection, the first servo motor 16 can drive the drag wheel 15 to rotate and drag the base body 2 through the rigid elastic member 14. The camera 10 can monitor the outside of the bridge body during the movement of the base body 2, and the cooperation between the swing member 8 and the pan-tilt 9 can facilitate the adjustment of the angle of the camera 10, improving the overall practicality. This device can also be used as a construction platform for construction workers to repair the bridge guardrail, etc. Through this research and development, the rental costs of equipment such as bridge inspection vehicles and lift trucks can be saved, not only saving the detection cost, but also improving the detection work efficiency and reducing the safety risks of detectors or construction workers. By installing the cooperation of the rigid elastic member 14 and the drag wheel 15, the drag wheel 15 can be in close contact with the bridge body 1, facilitating the drag wheel 15 to drag the base body 2 to move during rotation. The rollers 4 being made of rubber can increase the friction between the rollers 4 and the bridge body 1, enabling the base body 2 to be stably installed on the bridge body 1.
