Description

Technical Field

[0001] The utility model relates to the technical field of railway bridge detection, in particular to a portable detection device for automatic and continuous inspection of railway bridges. Background Art

[0002] Railway bridges are an indispensable part of the railway system. They not only carry the heavy task of trains crossing various natural and man-made obstacles, but also serve as an important link connecting different regions and promoting economic development. Beam bridges are the most common type of railway bridges, including simply supported beam bridges, continuous beam bridges and cantilever beam bridges. This type of bridge is widely used in railway engineering due to its simple structure, economy and practicality. Arch bridges have a place in railway bridges with their unique aesthetics and structural characteristics. Arch bridges mainly bear pressure and are suitable for scenes with large spans and visual effects. There are also cable-stayed bridges that support the bridge deck through inclined cables extending from the tower to both sides, which are suitable for large span coverage and have high technical content and visual effects. The suspension bridge, also known as the suspension bridge, supports the bridge deck through the main cable and the suspension cables perpendicular to the main cable, which can achieve super-large span coverage and is commonly used in the design of railway bridges across wide waters.

[0003] Railway bridge inspection is an important task to ensure railway traffic safety and improve transportation efficiency. Inspection is mainly carried out through two methods: manual inspection and track inspection vehicle inspection. Through inspection, potential problems can be discovered and dealt with to ensure the safety and stability of railway bridges.

[0004] However, the efficiency and accuracy of manual inspection are limited by the experience and ability of the inspectors, and the track inspection vehicle is large in size, and it is difficult to move the equipment to the track during inspection, which requires a lot of physical strength. In view of this, the present application proposes a portable detection device for automatic and continuous inspection of railway bridges. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a portable detection device for automatic continuous inspection of railway bridges, which has the advantages of easy portability and automatic inspection. It solves the problem that the efficiency and accuracy of manual inspection are limited by the experience and ability of the inspectors, and the track inspection vehicle is large in size, making it difficult to carry the equipment to the track during inspection, which requires a lot of physical strength.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable detection device for automatic continuous inspection of railway bridges, comprising a folding plate, two mounting bases fixedly mounted on the bottom of the folding plate, two rotating mounting plates fixedly mounted on the bottom of the mounting base, a rotating hollow shaft transmitted between the two rotating mounting plates, two mounting shafts slidably mounted inside the rotating hollow shaft, and a track wheel fixedly mounted on one end of the two mounting shafts away from each other;

[0007] The folding plate includes two mounting base plates hingedly connected by hinges, an insert plate fixedly mounted on the top of one of the mounting base plates, a plug hole opened on the top of the other mounting base plate, and a handle fixedly mounted on the side of the two mounting base plates away from each other.

[0008] The present application adopts the above-mentioned technical solution to set the track wheel at the bottom of the folding plate. When transporting, the two mounting base plates are folded together by hinges, and the plug plate is passed through the plug hole to fix the two mounting base plates. The two mounting base plates are lifted by the handle for easy carrying. When installing, the two mounting base plates are opened and the track wheel is placed on the track.

[0009] Furthermore, both ends of the rotating hollow shaft extend to the outside of the mounting base, and one end of the mounting shaft extends to the outside of the rotating hollow shaft.

[0010] The beneficial effect of adopting the above further solution is that the mounting shaft slides inside the rotating hollow shaft, and the distance between the two track wheels is adjusted, so as to facilitate docking with the track.

[0011] Furthermore, a travel motor is fixedly mounted on the inner side wall of one of the mounting bases, an output shaft is rotatably mounted on one side of the mounting base, and an output end of the travel motor is fixedly connected to one end of the output shaft.

[0012] The beneficial effect of adopting the above further solution is: starting the travel motor drives the output shaft to rotate.

[0013] Furthermore, a driving pulley is fixedly mounted on the surface of the output shaft, and a driven pulley is fixedly mounted on the surface of the rotating hollow shaft, and the driving pulley and the driven pulley are connected via a belt transmission.

[0014] The beneficial effect of adopting the above further scheme is that the output shaft rotates to drive the driving pulley to rotate, which drives the driven pulley to rotate through the belt, thereby driving the rotating hollow shaft to rotate, driving the installation shaft to drive the track wheel to rotate, so that the device moves on the track.

[0015] Furthermore, two ultrasonic detection devices are fixedly mounted on the bottom of one of the mounting substrates, and detection probes of the ultrasonic detection devices extend above the track.

[0016] The beneficial effect of adopting the above further solution is that the ultrasonic detection device performs ultrasonic detection on the rail to detect defects inside the rail, such as cracks, pores, etc.

[0017] Furthermore, a distance sensor is fixedly installed between the two installation shafts, and an angle sensor is fixedly installed on the top of the rotating hollow shaft.

[0018] The beneficial effect of adopting the above further scheme is that when the spacing of the tracks changes, the spacing between the two track wheels increases, driving the two mounting shafts to slide inside the rotating hollow shaft, driving the distance sensor to extend, measuring the change in the spacing of the tracks, and when the heights on both sides of the tracks are different, the rotating hollow shaft tilts, and the angle sensor detects the tilt angle.

[0019] Furthermore, a controller is fixedly installed at the bottom of the folding plate, the controller is electrically connected to the distance sensor and the angle sensor, and a communication module for transmitting data is provided in the controller.

[0020] The beneficial effects of adopting the above further solution are: the distance sensor is extended to measure the change in the spacing of the track, the angle sensor detects the inclination angle, and the inspection data is transmitted to the staff's receiving device through the communication module in the controller.

[0021] Compared with the prior art, the utility model provides a portable detection device for automatic continuous inspection of railway bridges, which has the following beneficial effects:

[0022] The portable detection device for automatic continuous inspection of railway bridges is designed by setting the track wheel at the bottom of the folding plate. When transporting, the two mounting base plates are folded together by hinges, and the plug plate passes through the plug hole to fix the two mounting base plates, which are lifted by the handle for easy carrying.
