Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to supporting equipment for bridge and road construction. Background Art

[0002] Bridge construction refers to the process of building a bridge according to the design content; in the process of road bridge construction, various equipment are often used. These equipment will vibrate when working. In order to prevent collapse caused by vibration, bridge construction support devices are often used. Bridge support devices are a commonly used auxiliary tool in the process of bridge construction, which serves as support and protection for the facility.

[0003] According to a Chinese patent application with patent number 202321063820.6, a supporting device for bridge construction of a bridge project includes: a base plate, rollers are fixedly installed at the four corners of the lower surface of the base plate, an adjustment plate is movably installed on one side of the top of the base plate, and the side of the adjustment plate away from the base plate is movably connected to a support plate; a shock-absorbing assembly, the shock-absorbing assembly is arranged on the side of the base plate close to the adjustment plate, the shock-absorbing assembly includes a shock-absorbing cylinder and a shock-absorbing column movably installed inside the shock-absorbing cylinder, a shock-absorbing spring is fixedly connected between the shock-absorbing cylinder and the shock-absorbing column; an adjustment assembly, the adjustment assembly is arranged on the side of the adjustment plate away from the base plate, and the adjustment The component includes a threaded rod and a threaded block movably installed outside the threaded rod. One end of the threaded rod is transmission-connected with a driven tooth. By setting a shock-absorbing component, when the bridge vibrates, the pressure will be transmitted to the base plate through the adjustment plate. At the same time, the shock-absorbing column and the shock-absorbing spring connected to the inside of the shock-absorbing cylinder will be compressed by the force, thereby achieving the effect of energy absorption and vibration relief. Considering the heavy weight of the bridge, in order to reduce the pressure on the shock-absorbing spring, a pressure relief spring is also provided. When subjected to a downward force, the adjustment plate will simultaneously transfer the pressure to the slider through the buffer strip, and the pressure relief spring will absorb the energy, thereby achieving double shock absorption to protect the bridge.

[0004] In order to facilitate the movement of the supporting equipment, the above patent installs universal wheels at the bottom of the base plate, but lacks a fixing mechanism. The universal wheels are easily slipped during the operation process to fix the supporting equipment for bridge construction of the bridge project only by the self-locking of the universal wheels, which poses certain installation risks. At the same time, the patent cannot clamp and fix bridge concrete construction panels of different widths. For this reason, we propose a supporting equipment for bridge and road construction.
