Problems solved by technology

[0003] The basic structure of the bridge is attached figure 1 And attached figure 2 As shown, the support column 1 is included, the support column 1 is provided with a base 2, the base 2 is provided with a bridge plate 3, and both sides of the bridge plate 3 in the width direction are provided with fences 4. A shock-absorbing device 5 is installed between the plate 3 and the base 2, and a deceleration belt 6 is installed on the bridge plate 3, so as to achieve the effect of improving the service life and safety of the bridge, but the installation method of the traditional deceleration belt 6 is relatively complicated , because the hardness of the traditional deceleration belt 6 is fixed, the buffering effect of the deceleration belt 6 on the vehicle is poor, resulting in cracks after the deceleration belt 6 is used for a long period of time, which reduces the use efficiency of the deceleration belt 6

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0039] as attached image 3 to attach Figure 5 As shown, a damping deceleration mechanism for a bridge includes an adjusting device 7, and the adjusting device 7 includes a bottom plate 703 arranged along the width direction of the bridge plate 3 and used to be movably connected with the bridge plate 3. The side is also provided with a detachable assembly that can be connected with the fence 4 at the corresponding position. On the end surface of the bottom plate 703 away from its contact with the bridge plate 3, there are a plurality of vertically arranged first elastic springs that are distributed along the width direction of the bridge plate 3 and vertically arranged. member 704, in this embodiment, the first elastic member 704 is a first spring, and the adjustment device 7 also includes a deceleration plate 705 arranged along the width direction of...

Abstract

The cushioning and speed reducing mechanism for the bridge comprises an adjusting device, the adjusting device comprises a bottom plate arranged in the width direction of a bridge plate and used for being movably connected with the bridge plate, and detachable assemblies capable of being connected with fences at the corresponding positions are further arranged on the two sides of the bottom plate in the width direction of the bridge plate. A plurality of first elastic parts which are distributed in the width direction of the bridge plate and are vertically arranged are arranged on the end face, away from the end face making contact with the bridge plate, of the bottom plate, the adjusting device further comprises speed reducing plates arranged in the width direction of the bridge plate, and the ends, away from the end connected with the bottom plate, of the first elastic parts are connected to the speed reducing plates at the corresponding positions. The end face, away from the end face connected with the first elastic part, of the speed brake is of an upwards-arched arc-shaped structure as a whole. According to the scheme, the buffering effect is good. Meanwhile, the air brake is not prone to cracking after being used for a long time, and therefore the use efficiency of the air brake is improved.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a damping and deceleration mechanism for bridges. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. building. [0003] The basic structure of the bridge is attached figure 1 And attached figure 2 As shown, the support column 1 is included, the support column 1 is provided with a base 2, the base 2 is provided with a bridge plate 3, and both sides of the bridge plate 3 in the width direction are provided with fences 4. A shock-absorbing device 5 is installed between the plate 3 and the base 2, and a deceleration belt 6 is installed on the bridge plate 3, so as to achiev...
