Description

Technical Field

[0001] This utility model relates to the field of road marking technology, and in particular to a road marking device for building engineering. Background Technology

[0002] Road marking devices for construction engineering are equipment used to draw markings on road surfaces. They use lines, arrows, text, vertical markings, raised pavement markers, and delineators to convey traffic information such as guidance, restrictions, and warnings to road users. These lines are crucial for traffic management and safety, providing clear visual guidance to help drivers and pedestrians comply with traffic rules, thereby improving road safety and traffic efficiency.

[0003] Existing road marking equipment for construction projects typically uses marking nozzles to spray paint onto the corresponding marking positions. However, the marking nozzles are difficult to adjust to different or special marking requirements, which limits the equipment's usability.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main purpose of this utility model is to provide a road marking device for building engineering, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A road marking device for construction engineering includes a base, with two casters installed on the lower left and lower right sides of the base. A pushing device is fixedly installed on the upper left side of the base. A storage tank is fixedly installed on the upper middle part of the base. A heating device is fixedly installed through the lower front end of the storage tank. A stirring device is fixedly installed on the upper middle part of the storage tank. A feed inlet is fixedly installed on the upper right side of the storage tank. A marking spraying device is fixedly installed on the upper right side of the base. A controller is fixedly installed on the upper front part of the base. An adjusting frame is fixedly installed through the middle of the right side of the base.

[0008] Preferably, the marking and spraying device includes a pneumatic diaphragm pump and a first servo motor. An extraction pipe is fixedly installed on the lower left end of the pneumatic diaphragm pump, and the extraction pipe is inserted and fixedly installed on the lower right end of the storage tank. A delivery pipe is fixedly installed on the upper right end of the pneumatic diaphragm pump. A positive and negative screw is fixedly installed at the output end of the first servo motor. Two sliders are threaded on the outer surface of the positive and negative screws. A nozzle is fixedly installed at the lower end of each of the two sliders. A connecting pipe is installed between each of the two nozzles and the delivery pipe. A sliding groove is opened at the lower end of the adjusting frame. The first servo motor is inserted and fixedly installed on the rear right end of the base. The pneumatic diaphragm pump is fixedly installed on the upper right end of the base. The pneumatic diaphragm pump draws the marking paint from the storage tank through the extraction pipe, and then delivers the paint to two nozzles through the delivery pipe and connecting pipe. The nozzles finally spray the paint onto the road surface below, thus completing the marking. In addition, the No. 1 servo motor drives the positive and negative screws to rotate in the slide groove. At this time, the two sliders on the positive and negative screws slide closer to each other, so that the distance between the two nozzles can be adjusted as needed to appropriately adjust the marking position.

[0009] Preferably, the pushing device includes a support frame, with adjustment slots on the upper part of the front inner wall and the upper part of the rear inner wall of the support frame. An electric telescopic rod is fixedly installed through the middle of the upper end of the support frame, and a pushing column is fixedly installed at the output end of the electric telescopic rod. The support frame is fixedly installed on the upper left side of the base. By pushing the pushing column upward with the electric telescopic rod, the pushing column slides within the two adjustment slots on the support frame, thereby allowing the position of the pushing column to be adjusted appropriately according to the user's height. At this time, the operator can push the entire device to the marked position on the road surface using the pushing column, and the universal wheels have a self-locking structure.

[0010] Preferably, the heating device includes a heater, a heating tube fixedly installed at the rear end of the heater, and a heat-conducting seat fixedly installed on the outer surface of the heating tube. The heater is fixedly installed at the lower front end of the storage tank. The heater drives the heating tube to generate heat within the heat-conducting seat, which then transfers heat to the coating material inside the storage tank. Combined with the stirring blades, this allows for effective heating of the coating material.

[0011] Preferably, the stirring device includes a second servo motor, with a stirring column fixedly mounted on the output end of the second servo motor. Several stirring blades are fixedly mounted on the outer surface of the stirring column, and the second servo motor is fixedly mounted in the middle of the upper end of the storage tank. By driving the stirring column with the second servo motor, the stirring blades on the column can stir the coating material in the storage tank as it rotates, preventing sedimentation of the coating.

[0012] Preferably, the two sliders are respectively mounted on the forward and reverse threads of the positive and negative screws.

[0013] Preferably, the positive and negative screws are rotatably mounted in the slide groove, and the slider is slidably mounted in the slide groove.

[0014] Preferably, the support frame is H-shaped.

[0015] Preferably, both the front and rear ends of the push column are fixedly installed with locking blocks, and the push column is slidably installed between the two adjustment slots through the locking blocks.

[0016] Preferably, the heat-conducting seat is fixedly installed on the lower inner wall of the storage vessel, and there is a gap between the heat-conducting seat and the stirring blade.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When road marking is required, the electric telescopic rod first lifts the push column upwards, which then slides within two adjustment slots on the support frame. This allows the position of the push column to be adjusted according to the user's height. The operator can then use the push column to move the entire device to the marking position on the road. Next, the pneumatic diaphragm pump is activated, drawing the marking paint from the storage tank through the extraction pipe. The paint is then delivered to two nozzles through the delivery and connecting pipes. The nozzles spray the paint onto the road surface below, completing the marking. Additionally, a servo motor drives the positive and negative screws to rotate within the sliding grooves. The two sliders on the positive and negative screws slide closer together, allowing adjustment of the distance between the two nozzles to suit the marking position, thus improving the device's practicality.

[0019] 2. While the device is moving, the stirring column is driven by the No. 2 servo motor. When the stirring column rotates, the stirring blades on it can stir the coating in the storage tank, avoiding the sedimentation of the coating and thus improving the marking effect of the device.

[0020] 3. When the temperature is low and affects the extraction of the coating, the heater drives the heating tube to heat the coating in the heat-conducting seat. The heat-conducting seat then transfers the heat to the coating in the storage tank. With the help of the stirring blades, the coating can be heated better, preventing it from solidifying due to cold. In addition, the design of the heat-conducting seat also prevents the heating tube from coming into direct contact with the coating. Attached Figure Description

The pneumatic diaphragm pump 20 draws the marking paint from the storage tank 6 through the extraction pipe 22, and delivers the paint to the two nozzles 26 through the delivery pipe 23 and the connecting pipe 27. The nozzles 26 finally spray the paint onto the road surface below, thus completing the marking. In addition, the first servo motor 21 drives the positive and negative screws 24 to rotate in the slide groove 28. At this time, the two sliders 25 on the positive and negative screws 24 slide closer to each other, so that the distance between the two nozzles 26 can be adjusted as needed to adjust the marking position appropriately.

[0032] The pushing device 3 includes a support frame 30. Adjustment grooves 33 are formed on the upper part of the front inner wall and the upper part of the rear inner wall of the support frame 30. An electric telescopic rod 31 is fixedly installed at the middle of the upper end of the support frame 30. A pushing column 32 is fixedly installed at the output end of the electric telescopic rod 31. The support frame 30 is fixedly installed on the upper left side of the base 1. The support frame 30 is H-shaped. Locking blocks are fixedly installed at both the front and rear ends of the pushing column 32, and the pushing column 32 is slidably installed between the two adjustment grooves 33 via the locking blocks. The electric telescopic rod 31 pushes the pushing column 32 upwards, causing the pushing column 32 to slide within the two adjustment grooves 33 on the support frame 30. This allows the position of the pushing column 32 to be adjusted appropriately according to the user's height. At this time, the operator can use the pushing column 32 to push the entire device to the marked position on the road surface. The universal wheels 8 have a self-locking structure.

[0033] The heating device 4 includes a heater 40, a heating tube 41 fixedly installed at the rear end of the heater 40, and a heat-conducting seat 42 fixedly installed on the outer surface of the heating tube 41.

Combined with the stirring blades 52, this allows for effective heating of the coating material.

[0034] The stirring device 5 includes a second servo motor 50, with a stirring column 51 fixedly mounted at the output end of the second servo motor 50. Several stirring blades 52 are fixedly mounted on the outer surface of the stirring column 51. The second servo motor 50 is fixedly mounted in the middle of the upper end of the storage tank 6.

The push column 32 then slides within the two adjustment slots 33 on the support frame 30, allowing the position of the push column 32 to be adjusted according to the user's height. At this time, the worker can push the entire device to the marking position on the road using the push column 32. Then, the pneumatic diaphragm pump 20 is started, which extracts the marking paint from the storage tank 6 through the extraction pipe 22 and delivers the paint to the two nozzles 26 through the delivery pipe 23 and connecting pipe 27. The nozzles 26 finally spray the paint onto the road surface below, thus completing the marking. In addition, the first servo motor 21 drives the forward and reverse screws 24 to...

This allows for adjustment of the distance between the two nozzles 26 to suit the marking position, improving the device's practicality. Simultaneously, the device moves, and the second servo motor 50 drives the stirring column 51. As the stirring column 51 rotates, its stirring blades 52 agitate the coating material in the storage tank 6, preventing sedimentation and improving the marking effect. Furthermore, when the temperature is low and affects coating extraction, the heater 40 drives the heating tube 41 within the heat-conducting seat 42 to heat the coating material.
