[0002] Road engineering refers to the entire process of planning, design, construction, maintenance and management of roads and the engineering entities involved. After the road construction is completed, it is necessary to use paint to draw arrow signs on the road surface according to requirements.

[0003] When painting roads, several construction workers usually measure the position where the arrow markings should be painted, and stick tape on the road surface to form the outline of the markings. Then, the markings are sprayed with a marking machine. During the spraying process, due to the specificity of the arrow marking style, workers are required to manually adjust the moving angle of the marking machine several times until the entire marking is sprayed. This method requires the cooperation of multiple people, is time-consuming, and has low spraying efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and to design an arrow marking device for road construction and a method for using the same.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An arrow marking device for road construction includes a U-shaped frame, wheels are arranged at the rear ends of the lower outer sides of both sides, a positioning wheel is arranged at the lower outer center of the front end, a handle is arranged at the upper outer side of one end, and further includes:

[0007] The contour baffle is arranged at the lower part of the U-shaped frame, and electric push rods are installed at the four corners of the contour baffle. The upper end of the electric push rod is installed with a push rod baffle, which is fixedly connected to the U-shaped frame, and a comprehensive arrow groove is opened at the center of the contour baffle. The comprehensive arrow groove is composed of a straight arrow groove, a left-turn arrow groove, a right-turn arrow groove and a straight groove. An outer sealing boss is arranged at the outer end of the upper surface of the contour baffle, and the outer sealing boss surrounds the outer side of the comprehensive arrow groove;

[0008] The arrow marking cold spray mechanism is arranged above the contour baffle and comprises:

[0009] The socket-type baffle is arranged above the contour baffle and embedded in the outer sealing boss. It is divided into a straight baffle, a left-turn baffle and a right-turn baffle according to the position. The straight baffle is located above the straight arrow groove and part of the straight groove and corresponds to its shape. The left-turn baffle is located above the left-turn arrow groove and corresponds to its shape. The right-turn baffle is located above the right-turn arrow groove and corresponds to its shape.

[0010] The spray pipe is arranged above the spigot-and-socket baffle, and is divided into a straight arrow pipe, a left-turn spray pipe and a right-turn spray pipe according to the position of the spigot-and-socket baffle. Several spray branches are installed below the spray branch. A square solid cone nozzle is installed at the lower end of the spray branch. A wrapping baffle is installed on the spray branch. A telescopic hose is installed between the wrapping baffle and the spigot-and-socket baffle. The telescopic hose is sleeved on the square solid cone nozzle.

[0011] The support frame is arranged above the socket-type baffle and is fixedly connected to the U-shaped frame.

[0012] It is connected to the straight arrow tube, the left-turn spray tube and the right-turn spray tube through sleeves, and three groups of magnet baffles are arranged on it, corresponding to the positions of the straight baffle, the left-turn baffle and the right-turn baffle respectively. Each group of magnet baffles has two and is located on both sides of the spray tube. A bar electromagnet is installed under the magnet baffle;

[0013] A straight spray pipe is arranged above one end of the straight groove of the contour baffle and is mounted on the U-shaped frame through a bracket, and a straight end spray head is arranged at the lower end thereof;

[0014] The cold spray driving mechanism is arranged above the front end of the U-shaped frame and includes:

[0015] The motor baffle is arranged on one side above the front end of the U-shaped frame, and the engine is installed on it. An engine-type hydraulic diaphragm pump is arranged on one side of the engine. A suction pipe is installed at the suction end of the engine-type hydraulic diaphragm pump, and a five-way pipe is installed at the discharge end of the engine-type hydraulic diaphragm pump. The five-way pipe is respectively connected to the straight arrow pipe, the left-turn spray pipe, the right-turn spray pipe and the straight spray pipe through a conveying hose, and is respectively controlled by an electromagnetic ball valve;

[0016] The battery baffle is arranged on the other side above the front end of the U-shaped frame, and the battery pack is installed on it.

[0017] Furthermore, the structure of the socket-type baffle adopts a boss-type panel, and its boss is movably embedded in the integrated arrow groove, and its shape is the same as the straight arrow groove, left turn arrow groove, right turn arrow groove and straight groove corresponding to the straight baffle, left turn baffle and right turn baffle.

[0018] Furthermore, a spray hole is arranged on the socket-type baffle, and the spray hole is located directly below the square solid cone nozzle. The spray holes are distributed on the straight baffle according to the shape of the straight arrow groove and the spraying area of ​​the square solid cone nozzle. The spray holes are distributed on the left baffle according to the left arrow groove and the spraying area of ​​the square solid cone nozzle. The spray holes are distributed on the right baffle according to the right arrow groove and the spraying area of ​​the square solid cone nozzle.

[0019] Furthermore, the bar-shaped electromagnet generates magnetic force after being energized, and adsorbs the corresponding straight-moving baffle, left-turning baffle and right-turning baffle under the corresponding bar-shaped electromagnet.

[0020] Furthermore, when the bar-shaped electromagnet is energized, it absorbs the corresponding spigot-type baffle and contracts the telescopic hose, so that the square solid cone nozzle passes through the spray hole and extends to below the spigot-type baffle.

[0021] Furthermore, the straight end of the straight baffle is conical, and two inclined surfaces thereof are provided with socket slots.

[0022] Furthermore, a triangular baffle is arranged at the rear side of the straight end of the straight baffle, a socket rod is arranged at one side of the triangular baffle, and the socket rod is movably inserted in the socket slot.

[0023] The present invention also provides a method for using the arrow marking device for road construction, comprising the following steps:

[0024] Step 1: Manually push the handle to move the U-shaped frame to the arrow mark, and align the integrated arrow groove of the contour baffle with the arrow mark to be marked. Then the staff can lock the positioning wheel to make it move in a straight line, and push the U-shaped frame to move a certain distance, so that the straight end nozzle moves to the starting spraying point of the concave arrow mark;

[0025] Step 2: The staff puts the barrel into the groove on the motor baffle, and inserts the extraction tube into the barrel, then controls the engine to start running, and controls the electromagnetic ball valve corresponding to the straight spray tube to open, and drives the engine-type hydraulic diaphragm pump to work, so that the engine-type hydraulic diaphragm pump delivers the marking paint in the barrel to the straight spray tube through the delivery hose, and sprays the marking paint onto the road surface through the straight end nozzle, and then drags the U-shaped frame at a uniform speed along the direction of the arrow by the handle, so that it gradually sprays the straight end of the arrow mark onto the road surface;

[0026] Step 3: When the worker moves a certain distance, the straight end of the arrow mark has been sprayed, and the worker controls the electromagnetic ball valve to close and the engine-type hydraulic diaphragm pump to stop working;

[0027] Step 4: According to the current arrow mark shape, the staff controls the bar electromagnet above the corresponding socket baffle to be powered off, and controls the bar electromagnets above the other socket baffles to be powered on, and then controls the electric push rod to start extending, so that it pushes the contour baffle down and places it on the ground. At this time, the integrated arrow groove on the contour baffle presents a groove corresponding to the arrow mark;

[0028] Step 5: According to the shape of the current arrow mark, the corresponding electromagnetic ball valve is controlled to open, and the engine-type hydraulic diaphragm pump is controlled to work, so that the marking paint is transported to the spray pipe through the delivery hose, and then the marking paint is sprayed onto the road surface through the spray branch pipe and the square solid cone nozzle. After spraying for a certain period of time, when the marking thickness reaches the standard, the electromagnetic ball valve is controlled to close and the engine-type hydraulic diaphragm pump stops working;

[0029] Step 6: At this time, the engine can be controlled to stop working, and then the electric push rod can be controlled to rise, so that the drag contour baffle can rise and reset, and then the U-shaped frame can be moved by continuing to move the handle to move it away from the painted arrow mark.

[0030] Furthermore, when the current arrow mark shape in step four is a left-turn arrow or a right-turn arrow, the staff manually takes out the triangular baffle and, based on the current arrow mark shape, flips the triangular baffle and inserts it into the rear side of the straight end of the straight baffle, so that the exposed groove of the integrated arrow groove is a left-turn arrow or a right-turn arrow.

[0031] Beneficial Effects

[0032] An arrow marking device for road construction and a method of using the same made by the technical solution of the present invention have the following beneficial effects:

[0033] 1. The adsorption of the straight baffle, the left-turn baffle and the right-turn baffle is controlled by electromagnets respectively, and the lifting and lowering of the contour baffle and the insertion of the triangular baffle are used to make the exposed position of the integrated arrow groove consistent with the arrow marking line to be drawn. Then, the arrow marking line cold spray mechanism can be used to spray the arrow marking line, which effectively reduces the operation workload of the staff, shortens the spraying time of the arrow marking line, and improves the spraying efficiency.

[0034] 2. Use a square solid cone nozzle to separate the arrow position and the oblique line part of the entire arrow mark into several square frames for spraying. This can ensure that the arrow mark is sprayed fully and evenly, and avoid uneven spraying or missed spraying points.

[0035] 3. Use the straight end nozzle to spray the straight end of the arrow mark first, and then spray the rest of the parts. This can prevent the positioning wheel from rolling over the sprayed marking line, ensure the integrity of the arrow marking line, and improve the spraying efficiency.

[0036] 4. Using the engine to drive the engine-type hydraulic diaphragm pump for spraying can reduce the power consumption of the device, thereby ensuring the battery life of the battery pack and allowing the device to be used for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] In the embodiment of the present invention, the engine 511 is used to drive the engine hydraulic diaphragm pump 512, so that the cold spraying operation does not need to use the power of the battery pack 521, thereby reducing the power consumption of the battery pack 521 and improving the endurance of the device, while ensuring the efficient operation of the spraying operation. At the same time, the setting of the battery pack 521 can facilitate the power supply to various electric components in the device, making the device more convenient to use.

[0078] In the embodiment of the present invention, the motor baffle 51 is arranged on one side above the front end of the U-shaped frame 1, and the battery baffle 52 is arranged on the other side above the front end of the U-shaped frame 1; it can be avoided that the motor baffle 51 covers the straight baffle 311, the left turn baffle 312 and the right turn baffle 313, so that after the spraying work is completed, the staff can quickly wipe the contour baffle 2 and recycle the marking paint.

[0079] Furthermore, the structure of the socket-type baffle 31 adopts a boss-type panel, and its boss is movably embedded in the integrated arrow groove 23, and its shape is the same as the straight arrow groove 231, the left-turn arrow groove 232, the right-turn arrow groove 233 and the straight groove 234 corresponding to the straight baffle 311, the left-turn baffle 312 and the right-turn baffle 313; the boss is embedded in the integrated arrow groove 23, so that the marking line can be sprayed strictly according to the exposed contour of the integrated arrow groove 23 during spraying, thereby ensuring the accuracy of the marking line spraying size.

[0080] In the embodiment of the present invention, a sealing cushion is provided on the outer side of the boss-type panel of the socket-type baffle 31 , which can reduce the external dust from falling into the outer sealing boss 24 , thereby ensuring the cleanliness of the inner side of the outer sealing boss 24 .

[0082] Furthermore, the bar electromagnet 333 generates magnetic force after being energized, and adsorbs the corresponding straight-moving baffle 311, left-turn baffle 312 and right-turn baffle 313 under the corresponding bar electromagnet 333, ensuring that the integrated arrow groove 23 can expose the corresponding groove according to the arrow marking line sprayed according to actual needs.

[0083] Furthermore, after the bar electromagnet 333 is energized, it absorbs the corresponding socket-type baffle 31 and contracts the telescopic hose 327, so that the square solid cone nozzle 325 passes through the spray hole 314 and extends to the bottom of the socket-type baffle 31; the square solid cone nozzle 325 can fully spray the corresponding straight arrow groove 231, the left-turn arrow groove 232, and the right-turn arrow groove 233, and avoid spraying above the socket-type baffle 31.

[0084] Furthermore, the straight end of the straight baffle 311 is tapered, and sockets are provided on its two inclined surfaces; the tapered shape of the straight end can be utilized to ensure that the left-turn and right-turn arrow signs can be fully exposed.

[0085] Furthermore, a triangular baffle plate 34 is provided on the rear side of the straight end of the straight baffle plate 311, and a socket rod 341 is provided on one side of the triangular baffle plate 34, and the socket rod 341 is movably inserted in the socket slot; by inserting the triangular baffle plate 34 into the rear side of the straight end of the straight baffle plate 311, it can be possible to cover more exposed triangular parts according to actual conditions, so that the exposed groove shape of the integrated arrow groove 23 is the same as the left-turn and right-turn arrow marks, so as to facilitate the spraying of the left-turn and right-turn arrows.

[0086] During the implementation of this technical solution, personnel in this field need to connect all electrical components in this case to an external power supply mechanism, and should select a suitable controller according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between each electrical component is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0087] When the present invention is specifically used, the following steps are adopted:

[0088] Step 1: manually push the handle 13 to move the U-shaped frame 1 to the arrow mark, and align the integrated arrow groove 23 of the contour baffle 2 with the arrow mark to be marked. Then the staff can lock the positioning wheel 12 to make it move in a straight line, and push the U-shaped frame 1 to move a certain distance, so that the straight end nozzle 41 moves to the starting spraying point of the concave arrow mark;

[0089] Step 2: The staff puts the barrel into the groove on the motor baffle 51, and inserts the extraction tube 513 into the barrel, then controls the engine 511 to start running, and controls the electromagnetic ball valve 516 corresponding to the straight spraying tube 4 to open, and drives the engine type hydraulic diaphragm pump 512 to work through the engine 511, so that the engine type hydraulic diaphragm pump 512 delivers the marking paint in the barrel to the straight spraying tube 4 through the delivery hose 515, and sprays the marking paint onto the road surface through the straight end nozzle 41, and then drags the U-shaped frame 1 at a uniform speed along the arrow direction through the handle 13, so that it gradually sprays the straight end of the arrow mark onto the road surface;

[0090] Step 3: When the worker moves a certain distance, the straight end of the arrow mark has been sprayed, and the worker controls the electromagnetic ball valve 516 to close, and at the same time controls the engine-type hydraulic diaphragm pump 512 to stop working;

[0091] Step 4: According to the current arrow mark shape, the staff controls the bar electromagnet 333 above the corresponding socket-type baffle 31 to be powered off, and controls the bar electromagnets 333 above the other socket-type baffles 31 to be powered on, and then controls the electric push rod 21 to start extending, so that it pushes the contour baffle 2 down and places it on the ground. At this time, the integrated arrow groove 23 on the contour baffle 2 presents a groove corresponding to the arrow mark;

[0092] Step 5: According to the shape of the current arrow mark, the corresponding electromagnetic ball valve 516 is controlled to open, and the engine-type hydraulic diaphragm pump 512 is controlled to work, so that the marking paint is delivered to the spray pipe 32 through the delivery hose 515, and then the marking paint is sprayed onto the road surface through the spray branch pipe 324 and the square solid cone nozzle 325. After spraying for a certain period of time, when the marking thickness reaches the standard, the electromagnetic ball valve 516 is controlled to close and the engine-type hydraulic diaphragm pump 512 stops working;

[0093] Step 6: At this time, the engine 511 can be controlled to stop working, and then the electric push rod 21 can be controlled to rise, so that the drag contour baffle 2 rises and resets, and then the handle 13 is continued to move the U-shaped frame 1 to move it away from the sprayed arrow mark.

[0094] When the present invention is used specifically, when the current arrow mark shape in step four is a left-turn arrow or a right-turn arrow, the staff manually takes out the triangular baffle 34, and according to the current arrow mark shape, flips the triangular baffle 34 and inserts it into the rear side of the straight end of the straight baffle 311, so that the exposed groove of the integrated arrow groove 23 is a left-turn arrow or a right-turn arrow.

[0095] When the present invention is implemented, after the device is used, the staff controls the electric push rod 21 to extend and controls all the bar electromagnets 333 to be energized to work, so that the contour baffle 2 drops to the ground and the integrated arrow groove 23 is fully opened. Then the staff can clean the marking paint attached to the entire contour baffle 2, and the marking paint on the inner side of the outer sealing boss 24 can be recycled to reduce waste.

[0096] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
