Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge maintenance spraying, in particular to a road and bridge maintenance spraying device. Background Art

[0002] Roads and bridges generally refer to roads and bridges. Roads generally refer to highways, urban roads, and places under the jurisdiction of a unit but where social motor vehicles are allowed to pass, including squares, public parking lots and other places for public passage. Roads, in terms of the meaning of the word, are infrastructure for various trackless vehicles and pedestrians to pass through. Bridges generally refer to structures erected on rivers, lakes, and seas to enable 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 buildings that cross mountain streams, poor geology, or meet other traffic needs to make passage more convenient. Bridges generally consist of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles. The substructure includes abutments, piers, and foundations. The supports are force transmission devices installed at the supporting locations of the span structure and the piers or abutments. The ancillary structures refer to the bridgehead slabs, conical slope protection, revetment, diversion projects, etc. After the construction of roads and bridges is completed, maintenance spraying devices are generally used to spray water on the roads and bridges for maintenance.

However, since the device does not have the function of removing scale, a large amount of scale will accumulate on the inner wall of the water storage tank after the device is used for a long time, which will easily affect the normal use of the device and cannot meet the use requirements;

[0005] 2. The existing road and bridge maintenance spraying device does not have the function of buffering and shock absorption. This also causes the device to vibrate too much due to the bumps of the road during the maintenance spraying process, which in turn causes the precision parts on the device to loosen or be damaged, indirectly reducing the service life of the device and making it inconvenient to promote. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a road and bridge maintenance spraying device, which solves the problems that the current device does not have a scale removal function, resulting in a large amount of scale being accumulated on the inner wall of the water tank after long-term use, which may easily affect the normal use of the device, and does not have a buffering and shock-absorbing function, resulting in the device being prone to excessive shaking due to road bumps during the maintenance spraying process, thereby causing the precision components on the device to become loose or damaged.

[0016] Beneficial effects:

[0017] 1. This road and bridge maintenance spraying device is provided with a water tank, a motor, a rotating shaft, a connecting rod, a bracket, a scraper, a cleaning brush, a fixed block, a water inlet and a debris discharge port. When removing scale, by starting the motor, the bracket is driven to rotate along the inner wall of the water tank, so that the scraper can rotate in contact with the inner wall of the water tank to scrape off the attachments on the inner wall of the water tank. At the same time, by providing a cleaning brush, the attachments on the inner wall of the water tank that have not been scraped off can be brushed for the second time, thereby improving the effect of the device in removing scale. This design enables the device to have the function of removing scale, avoids the problem that a large amount of scale will accumulate on the inner wall of the water tank after the device is used for a long time, which will easily affect the normal use of the device, and meets the use requirements.

[0018] 2. This road and bridge maintenance spraying device is equipped with a shock-absorbing component, a buffer frame, an elastic ball, a limit block, a damping rod, and a compression spring. When facing the vibration caused by bumps, the compression spring is squeezed by the water tank, which in turn drives the limit block to squeeze the elastic ball. At the same time, the elastic force of the elastic ball and the compression spring reacts to the water tank, weakening and reducing the impact force and vibration amplitude caused by external bumps, thereby improving the buffering and shock-absorbing performance of the device. This design enables the device to have the function of buffering and shock-absorbing, avoiding the problem of excessive vibration amplitude caused by road bumps during the maintenance spraying process, which in turn causes the precision parts on the device to become loose or damaged, indirectly improving the service life of the device and facilitating promotion.
