The bridge construction marking device described in the aforementioned document has the following shortcomings:

[0004] 1. Lack of warning equipment.

[0005] 2. The device lacks obstacle removal measures, so the road surface needs to be cleared in advance.

[0006] 3. The device does not take into account issues such as bridge slope, and does not provide corresponding solutions for problems such as vehicle slippage and spraying caused by slope. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bridge construction marking device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A bridge construction marking device includes a chassis. A pair of hydraulic shock absorbers are installed at both ends of the front side of the chassis bottom, with a front wheel mounted on the outward-facing side of each shock absorber. A rear wheel is bolted to the rear side of the chassis bottom, and a handlebar is connected to the rear wheel. The handlebar controls the rotation of the rear wheel, and a grip is located at the top end of the handlebar. A handbrake is located on one side of the grip. A foot brake is also installed behind the rear wheel; both the foot brake and the handbrake control the rear wheel. A paint tank is fixed to the top of the chassis with screws. The paint tank has an exhaust port away from the handlebar, and a feed port is located on the top of the paint tank. The feed port has a handle for easy opening. A discharge port is installed on the lower side of the paint tank.

[0010] As a further embodiment of this utility model: a cover plate is installed on the outside of the discharge port by a hinge, the cover plate is connected to a lifting iron bar, and a discharge gate is installed on the other end of the lifting iron bar by bolts.

[0011] As a further embodiment of this utility model: a fixing rod is fixedly installed on the bottom side of the chassis at the discharge port, and a funnel is fixedly connected to the fixing rod. The funnel and the outlet of the discharge port are aligned. A cantilever is installed on the funnel in a swingable manner. A nozzle is installed on the cantilever. A row of nozzles is provided on the bottom surface of the nozzle. The nozzle is flexibly connected to the output end of the funnel through a hose.

[0012] As a further improvement of this utility model: a detachable connector is installed on the front side of the chassis, a telescopic rod is fixedly installed on the connector, and a clearing plate is installed on the other end of the telescopic rod.

[0013] As a further improvement of this utility model: a power supply mechanism is installed on the upper surface of the chassis, and the power supply mechanism is connected to a heating pad via a wire and installed below the paint tank. A spare material tank is detachably installed on the power supply mechanism.

[0014] As a further improvement of this utility model: a warning light bracket is installed on one side of the chassis, and a warning light is provided on the top of the warning light bracket.

[0015] As a further improvement of this utility model, the paint tank is provided with several protective bars on its outer side.

[0016] As a further improvement of this utility model, a stirring rod penetrating the interior of the paint tank is also provided at the top of the paint tank.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By installing hydraulic shock absorbers, the impact of the road surface on the device can be reduced during driving. The handlebars and grips can control the direction of the rear wheel. The handbrake can assist the staff in manually braking. The foot brake serves as a parking device to prevent the device from slipping on the bridge surface and causing accidents. The paint tank can store the marking paint. The vent can promptly dissipate the heat generated in the paint tank. The feed port facilitates the addition of paint.

[0019] 2. By setting a discharge port, the heated and melted paint can be guided out of the paint tank; the cover plate can be closed by manually pulling the discharge gate to drive the lifting iron bar, so that the paint will not flow out of the paint tank.

[0020] 3. By setting a fixing rod, the funnel can be fixed on the device. The paint is fed into the spray head through the hose by the funnel, and then sprayed onto the construction surface by the nozzle. The cantilever can keep the spray head facing the construction surface under the action of gravity, so as to avoid the slope of the bridge from affecting the spraying of the device.

[0021] 4. By setting up a clearing plate, debris on the travel route can be cleared before spraying, ensuring the normal operation of the line marking work. The sharp corners of the clearing plate can also serve as guide markers, allowing workers to position the line marking device in advance by using the sharp corners. At the same time, the telescopic rod can adjust the height of the clearing plate according to the road surface to adapt to different road conditions. Furthermore, if the clearing facility is not needed, the mechanism can be removed from the device by removing the connecting parts.

[0022] 5. By setting up a power supply mechanism, electricity can be transmitted to the heating pad, which heats the paint can. At the same time, the spare material tank set above the power supply mechanism can store excess paint, increasing the total amount of paint carried and thus improving the endurance of the marking process.

[0023] 6. By setting warning lights, the device can serve as a warning during operation, alerting surrounding vehicles and pedestrians to avoid it.

[0024] 7. By installing protective bars, it is possible to effectively prevent personnel from accidentally coming into contact with the tank and avoid burns.

[0025] 8. The stirring rod can stir the added paint in the tank, allowing it to be heated evenly. Attached Figure Description
