Description

Technical Field

[0001] The utility model relates to the technical field of bridge repair, and more specifically to a bridge hanging plate fast cutting saw. Background Art

[0002] Bridge hanging plates are structures installed on the edge of bridges to decorate the appearance of bridges. They are usually connected to bridge crash piers or bridge deck structures by pre-buried steel bars. Due to the influence of traffic environment, service life and natural climate, the hanging plates of many domestic bridges often become loose and fall off after long-term use, which poses a huge safety hazard to vehicles and pedestrians passing under the bridges. Therefore, bridge hanging plates with such safety hazards need to be removed.

[0003] For example, the utility model with the authorization announcement number CN213412109U discloses a fast cutting saw for bridge hanging plates, including a mounting plate, a motor, a driving wheel, a cutting saw, a driven wheel, a belt and a protective cover, wherein a motor is fixedly mounted on one end of the upper surface of the mounting plate, a driving wheel is fixedly connected to the power output end of the motor, a cutting saw is fixedly mounted on the other end of the upper surface of the mounting plate, a driven wheel is fixedly connected to one side of the cutting saw, the driven wheel and the driving wheel are connected by a belt, a protective cover is fixedly mounted above the cutting saw, a rotating shaft is movably inserted in the middle of the mounting plate, the mounting plate is movably connected to a gantry through the rotating shaft, and the mounting plate is located at the bottom of one end of the gantry, and a counterweight platform is fixedly welded to the bottom of the other end of the gantry. When in use, the utility model can hang the cutting device on the outside of the bridge guard plate, and the operator can operate it while standing on the bridge deck, which is safer to use, and at the same time has a higher cutting effect, better cutting accuracy, and is faster to use.

[0004] When using the above-mentioned comparative document, the cutting device can be hung on the outside of the bridge guard plate, and the operator can operate it while standing on the bridge deck. It is safer to use, and the cutting effect is higher, the cutting accuracy is better, and it is faster to use. However, when cutting, the cutting surface will have many uneven areas or many burrs. In this way, when installing a new bridge scraper, if it is not polished, a gap will be caused between the bridge scraper and the bridge, which will pose a safety hazard. Utility Model Content
