Description

Technical Field

[0001] The invention relates to the technical field of road marking, in particular to a double-kettle heating cycle hot-melt high-speed road marking vehicle. Background Art

[0002] In recent years, the construction of expressways and roads at all levels has been continuously developed. Highway marking is the basic condition to ensure vehicle safety. There are a large number of new roads that need new markings, and the old markings on old roads need to be redrawn. Therefore, the market needs a large number of various forms of marking machinery.

[0003] When operating traditional road marking machines, operators need to stand on the road surface or sit on a small road marking machine. Various vehicles passing by will pose a great threat to the safety of the operators, and accidents caused by this often occur. At the same time, traditional road marking machines have a low driving speed. Due to the slow melting efficiency, it is necessary to wait until the hot melt kettle melts the material before the marking operation can be carried out, which seriously affects the speed of the marking operation. The transfer needs to be transported by truck or flatbed truck, which greatly affects the production efficiency.

[0004] As the social division of labor becomes more and more specialized and labor costs become higher and higher, higher requirements are put forward for road marking equipment: high marking efficiency, safety, no road closure during construction, no impact on traffic, and high integration. Traditional hand-pushed and driving road marking machines are increasingly unable to meet the needs.

[0005] The hot melt kettles of existing hot melt marking equipment on the market are mostly divided into two types: direct heating and indirect heating. Both of them place the material in the barrel and heat the outer wall of the barrel, and the heating efficiency is slow. When the marking machine is operating, due to the progress requirements of the marking project, the corresponding marking project volume must be completed in a short time, which requires multiple auxiliary raw material transport vehicles. Due to the slow melting efficiency of traditional hot melt kettles, several hot melt kettles are often required to work at the same time to meet the requirements of the project progress, which results in a lot of accompanying equipment, a lot of personnel, a lot of expenses, and a slow construction speed. Summary of the invention

[0030] Compared with the prior art, the present invention has outstanding substantial features and significant progress. Specifically, during the marking operation, the present invention pulls out the connecting pin, flips the guide rod forward and downward so that the front end of the guide rod is set forward and downward, the guide wheel is supported on the ground by rolling, and the lower end of the guide needle is supported on the ground by sliding. The driver can drive the highway marking vehicle along the pre-marked line on the ground according to the guide needle. The engine is started, the front transmission shaft drives the transfer case to operate, and the relevant buttons are operated to turn the vehicle into a hydraulic driving state. The transfer case transmits power to the hydraulic pump, and the hydraulic pump transfers the hydraulic oil in the hydraulic oil tank through the hydraulic oil circuit. The oil is pumped to the associated motors, telescopic cylinders and hydraulic valve groups through the hydraulic oil filter. When a certain action function needs to be realized, the associated hydraulic valve group channel is opened through the electrical control button, and the associated motor or telescopic cylinder is activated, thereby making the related action module run; when the operation forward module key is started, the transfer case transmits power to the rear axle drive shaft, and the vehicle moves forward. The paint required for construction is placed in the storage box frame, and the paint is transported to the kettle assembly through the feeding conveyor. According to the requirements of the marking position, the operating table assembly is slid to the corresponding position for fixing, and the corresponding function buttons are operated on the control panel to perform the marking operation, and the powdered hot melt After the material enters the upper cavity of the outer kettle body of the kettle body assembly through the feeding conveyor, the stirring mechanism stirs the powdered hot melt material, and the powdered hot melt material exchanges heat with the high-temperature heat-conducting oil in the heat-conducting interlayer of the outer kettle body and initially melts. The initially melted hot melt material is efficiently heated by the heat exchange tube group in the middle kettle body of the kettle body assembly, and becomes hot melt material that reaches the marked state and enters the lower cavity of the outer kettle body of the kettle body assembly. The hot melt material that reaches the marked state passes through the feed pump, and the feed pump circulates a part of the hot melt material that reaches the marked state through the feed pipe to the upper cavity of the outer kettle body of the kettle body assembly for further heating the powdered hot melt material, and the feed pump transfers another part of the hot melt material that reaches the marked state to the upper cavity of the outer kettle body of the kettle body assembly. The hot melt is transported to the double-sided marking system through the feed pipe for marking. The hot melt in powdered state is efficiently circulated and heated, which greatly improves the heating efficiency and ensures the continuity of the marking operation. The hot melts of the two kettle assemblies can be connected or independent of each other to meet the different needs of double-color, same-color or double-sided marking. After the hot melt reaches the marking state, when the marking operation starts, the second valve is opened, the telescopic function of the marking device on the controller is turned on, and the steering wheel of the operating table assembly is operated to control the upper swing arm assembly to perform a rotary motion with the first hinge as the center, thereby maximizing the movement of the lower parts of the lower swing arm assembly;At the same time, the lower end of the upper swing arm oil cylinder and the rear end of the lower swing arm oil cylinder are both rotatably connected to the lower part of the upper swing arm assembly through one end of the third pin shaft, and the front end of the lower swing arm oil cylinder is rotatably connected to the lower swing arm assembly through the second pin shaft. When in use, it is necessary to control the lower swing arm assembly to make a rotational motion with the second pin shaft as the center, so that the marking mechanism connected to the lower part of the lower swing arm assembly moves to a predetermined position, the lower part of the roller brush contacts the road surface, and the air valve (equivalent to the pneumatic valve) of the marking device is controlled to operate, and the feed pipe conveys hot melt to the marking mechanism. The vehicle moves forward to start the marking operation, and at the same time, the roller brush motor is controlled to work, and the roller brush motor drives the central axis of the roller brush to rotate, so that the roller brush rotates to clean the road, ensuring that the road surface in front of the marking mechanism is clean, and the marking mechanism evenly applies the hot melt on the road, and the two marking mechanisms can work at the same time, so that two marking lines can be marked at one time, and the marking efficiency is high. The heat transfer oil pipe injects high-temperature heat transfer oil into the heat transfer ring cavity in the pipe wall of the feed pipe, thereby heating the hot melt in the feed pipe to ensure that the hot melt entering the marking mechanism The molten material is kept warm to keep the fluidity of the hot melt good. When it is necessary to add glass beads to the pressurized glass bead tank, the vortex feeding device is started, and the glass beads are pumped into the pressurized glass bead tank through the feeding pipe. When the marking operation is performed, the marking key is started, the air control valve of the glass bead spray gun is opened, and the glass beads begin to spray. By adjusting the adjustment shaft of the glass bead spray gun, the amount of glass beads is adjusted to achieve the marking quality with the best reflection coefficient. After the air compressor start button on the control panel is started, the hydraulic control valve channel of the air compressor motor is opened, and the air compressor is operated by the power transmitted by the air compressor motor. The compressed air produced by the operation of the air compressor is dried in the dryer and then enters the air storage cylinder for pressure-maintaining storage. Each air-using component takes compressed air from the air storage cylinder as needed. When a function key of an air-using mechanism on the control panel is started, the compressed air in the air storage cylinder passes through the corresponding associated pneumatic solenoid valve, pressure gauge, pneumatic triplet, pressure regulating valve, valve, etc. to reach the corresponding cylinder or other air-using mechanism, and the cylinder or other air-using mechanism is actuated to achieve the corresponding function. Before the marking operation, according to the reflective coefficient of the line type required by the construction, the valve state is adjusted through the pressure gauge data connected to the glass bead tank, and the pressure of the glass bead tank and the glass bead spray gun is adjusted to make the spraying amount of the glass beads reach the appropriate spraying amount required for the marking operation. ;

[0031] When the line marking vehicle needs to be started, turn on the main power switch and follow the normal vehicle starting operation to realize the normal driving function of the vehicle. When the line marking operation is in progress, the hydraulic driving mode can be turned on by operating the corresponding buttons in the cab. After turning on the hydraulic driving mode, the corresponding function keys on the control screen can be operated to perform the corresponding function operations. When the line marking operation requires an intermediate transfer, the special function can be turned on in the cab to realize the hot melt insulation heating function during the special time period.

[0032] The present invention can realize high-speed, efficient and safe marking of road markings, does not close the road during construction, does not affect normal traffic, and is highly integrated. BRIEF DESCRIPTION OF THE DRAWINGS
