Description

Technical Field

[0001] The utility model relates to the technical field of subway monitoring, in particular to an image collector for subway monitoring. Background Art

[0002] Subway is a form of rail transportation, referring to an urban rail transit system that mainly operates underground, that is, "underground railway" or "subway"; many such systems may be converted into ground or elevated sections outside the city center in order to adapt to the construction environment and consider the construction and operation costs. The subway is an urban rail transit system that covers all kinds of underground and above-ground road rights in urban areas, with high density and high capacity. The subway in Taiwan, China calls it "MRT". During the construction of the subway and after the subway is in operation, monitoring is often required, so various monitoring equipment is needed, and the image collector for subway monitoring is a frequently used device. For example, a graphic collector is needed at the support of the subway tunnel to observe whether the support is deformed.

[0003] However, some subway detection image collectors are now installed on the side of the track. Traditional image collectors are mostly fixed directly on the mounting plate. The vibration generated by the passing train can easily cause certain damage to the image collector body. For this reason, we propose an image collector for subway monitoring to solve the above problem. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an image collector for subway monitoring, comprising a base plate and an image collector body, the top of the base plate is fixedly connected to two cylinders, the inside of the cylinder is slidably connected to a circular plate, the top of the circular plate is fixedly connected to a vertical rod, the top of the vertical rod extends to the outside of the top of the cylinder and is fixedly connected to the top plate, the inside of the cylinder is fixedly connected to an elastic airbag, the top of the base plate is provided with two limit grooves, a limit rod is fixedly connected between the left and right inner walls of the limit groove, a slider is slidably connected to the outside of the limit rod, a spring is fixedly connected between the slider and the inner wall of the limit groove, the spring is movably sleeved on the outside of the limit rod, the tops of the two sliders are fixedly connected to the same arc-shaped spring piece, and the top of the arc-shaped spring piece is fixedly connected to the top plate.

[0006] Further preferably, a damper is fixedly connected to the top of the bottom plate, and a movable end of the damper is fixedly connected to the bottom of the top plate.

[0007] Further preferably, the top of the top plate is fixedly connected to a mounting plate by two hexagonal bolts.

[0008] Further preferably, the top of the mounting plate is rotatably connected to a connecting rod via a hinge.

[0009] Further preferably, the image collector body is rotatably connected to the connecting rod via a hinge.

[0010] Compared with the prior art, the utility model has the following beneficial effects: when the utility model is used, the mounting plate is fixed to the top of the top plate by the hexagonal bolts, and then the angle and height of the image collector body are adjusted by the adjusting knobs arranged on the connecting rods. When the train passes and generates vibrations, the image collector body is subjected to impact forces from above and below, and the top plate moves downward, driving the vertical rod and the movable end of the damper to move downward, and the vertical rod drives the circular plate to slide downward inside the cylinder, and the elastic airbag is squeezed. The top plate moves downward and squeezes the arc-shaped spring sheet at the same time, and the arc-shaped spring sheet drives the two sliders to move away from each other, and the slider slides on the outside of the limit rod, and the spring is compressed. Under the mutual cooperation of the spring, the arc-shaped spring sheet, the elastic airbag and the damper, a buffering effect is achieved, which avoids certain damage to the image collector body caused by the impact force generated by the vibration, and the utility model has high practicality.
