Reminding device convenient to move for road and bridge construction

Abstract

The invention discloses a reminding device convenient to move for road and bridge construction, and belongs to the technical field of roads and bridges. The reminding device convenient to move for road and bridge construction comprises a sleeve rod, a clamping plate A is fixedly arranged on the upper side of the rear end of the sleeve rod, a threaded rod is arranged at the upper end of the clamping plate A, a guide rod is fixedly arranged on one side of the lower end of the clamping plate A, a clamping plate B is arranged on the lower side of the clamping plate A, a cavity is formed in one containing box, a fixing shaft is arranged in the cavity, a torsion spring is fixedly arranged at the end of the fixing shaft, and two guide grooves are symmetrically formed in the lower end of an extrusion plate. By arranging a screw rod, two sliding blocks A can be driven through a threaded block and a supporting rod B when the screw rod rotates, so that the distance between the two sliding blocks A and a warning board is changed, the two warning boards can be located on the two sides of a construction site, the design is reasonable, a ship can be effectively helped to determine the construction position, and therefore, the ship can smoothly bypass the lower side of the construction site, and accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of roads and bridges, in particular to a mobile reminder device for road and bridge construction. 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, during the bridge construction process, reminders such as warning signs or warning signs are usually required to remind passers-by. or passing vehicles. The patent document with the publication number CN110965491A in the prior art provides a mobile reminder device for road and bridge construction. The device can easily adjust the height of the warning sign by setting the hydraulic rod, the first motor, the first rotating rod and other structures and can Rotate to facilitate the observation of passers-by and vehicles. Although the device has many beneficial effects, the foll...

AI Technical Summary

Problems solved by technology

Although the device has many beneficial effects, the following problems still exist: during bridge maintenance, the construction site needs to be frequently changed, and since bridge construction is a high-altitude operation, heavy objects fall during construction and easily hit passing ships, resulting in damage to passing ships , and there are serious potential safety hazards. It is difficult for existing devices to remind passing ships of the area where the bridge is under construction. It is difficult for ships to determine the edge of the construction site when they are circumventing. When the ship does not completely bypass the lower side of the construction site, there will still be potential safety hazards. , and the position of the reminder device needs to be changed frequently, the reminder effect is poor, and the work efficiency is low. In view of this, we propose a mobile reminder device for road and bridge construction
