Description

Technical Field

[0001] The invention relates to the field of road marking equipment, and in particular to an environmentally friendly road indicator line marking device for bridge maintenance. Background Art

[0002] Bridges are a key component of transportation infrastructure. They are exposed to the natural environment for a long time and are subjected to multiple external forces such as vehicle loads, wind loads, and water erosion, which often cause the marking lines on the road surface to wear and fall off. During subsequent maintenance, the bridge road needs to be re-lined. Road marking refers to the use of lines, arrows, text, facade markings, raised road signs, and contour marks on the road surface to convey traffic information such as guidance, restrictions, and warnings to traffic participants. Its function is to control and guide traffic. It can be used in conjunction with signs or alone. Thermoplastic marking is one of the most widely used types of road marking in my country. However, the width of spray-type road marking varies in different places, so the width of the marking needs to be adaptively adjusted. The existing width adjustment method is complex and costly. At the same time, traditional road marking equipment still requires manual scraping and cleaning of the road marking area before marking, and spraying of primer.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can use the feed pump to extract the paint through the extraction pipe and spray it through the nozzle at the end of the straight cylinder to realize the marking of ordinary indicator lines. When the road marking machine is pushed to mark, the scraper can be used to scrape and clean the ground at the marking location, so that the redundant or loose stones on the ground can be removed, which is beneficial to the subsequent marking work. At the same time, the fan blades can be driven to rotate by the work of the double-headed motor, and the rotation of the fan blades can form an airflow. Part of the airflow will enter the top cover through the conduit three, and then the airflow will be sprayed out under the guidance of the air guide cover. The loosened stones and dust on the ground can be blown away by the continuously sprayed airflow. The arc design of the air guide cover port can effectively increase the cleaning area of ​​the airflow, which is beneficial to practical use, thereby effectively improving the firmness of the paint adhesion during subsequent marking.

[0016] 2. The clean oil inside the oil storage tank can be pumped out through the pump body inside the turntable, so that the clean oil will enter the through pipe and spray out, so as to realize the spraying of the base oil before the ground is marked. At the same time, during the operation of the double-headed motor, the bottom driving end of the double-headed motor can drive the turntable to rotate, so as to realize the uniform distribution of the base oil, which is beneficial to the subsequent paint spraying work. At the same time, people can open and close the solenoid valve at one end of the conduit according to actual needs. When the solenoid valve is opened, part of the airflow generated by the rotation of the fan blades will enter the air chamber through conduit one, and the airflow can be introduced into the rubber bag through the air chamber. The rubber bag can be evenly expanded by the incoming gas, so as to realize the adjustment of the oiling range of the rubber bag, which is beneficial to actual use.

[0017] 3. When marking large-size indicator lines, people can start the servo motor, which can drive the bevel gear to rotate. The rotation of the bevel gear can drive the bevel gear rings on the upper and lower sides to rotate synchronously. The bevel gear ring can drive the rotating bin to rotate, and the opening and closing of the connecting head and the rotating rod can be realized. The marking range can be adjusted by opening and closing the rotating rod. When marking, people can open the valve body inside the rotating bin, so that the paint will enter the rotating bin from the straight cylinder, and then the paint will enter the rotating rod through the connecting head and be sprayed out through the nozzle. The hub motor can drive the retaining ring to rotate, and the retaining ring can use the retaining column and the chuck to drive the rotating rod to deflect, so as to adjust the spraying direction of the rotating rod, so that people can spread the paint in the contour line in situ, avoiding the need for secondary widening or replenishing.

[0018] 4. By controlling the opening and closing of the rotating rod during movement, the arrow drawing work can be achieved in one go, avoiding the need to use molds or secondary marking. During the marking process, part of the airflow generated by the rotation of the fan blades will enter the base through the second conduit, and the semiconductor refrigeration plate inside the base can achieve rapid cooling of the incoming gas. The cooled gas will then enter the top bin through the connecting pipe and be ejected through the air outlet at the bottom of the quick-drying rack, thereby achieving rapid cooling and solidification of the paint at the bottom marking area, which is beneficial to avoid the subsequent destruction of the marking by vehicles or pedestrians, and is beneficial to actual use.

At the same time, by controlling the opening and closing of the rotating rod 110 during movement, it is possible to achieve a one-time arrow drawing work, avoiding the need to use a mold or secondary marking. During the marking process, part of the airflow generated when the fan blade 121 rotates will enter the base 143 through the conduit 122, and the semiconductor refrigeration plate inside the base 143 can achieve rapid cooling of the incoming gas. After that, the cooled gas will enter the top bin 131 through the connecting pipe 130, and will be sprayed out through the air outlet 141 at the bottom of the quick-drying rack 107, so as to achieve rapid cooling and solidification of the paint at the bottom marking, which is beneficial to avoid the subsequent vehicles or pedestrians passing by to damage the marking, which is beneficial to practical use.
