[0028] The automatic spraying device for railway freight car body marking comprises an electric tricycle 100, an air compressor, an access platform, and a spraying and ultraviolet module. The electric tricycle is obtained by purchase and is modified based on the electric tricycle. Preferably, the electric tricycle 100 is a tricycle driven by a lithium battery. The mature new energy electric tricycle in the prior art is used as a platform carrier, has the characteristics of strong mobility, and the power supply required for spraying work can be directly connected to the power battery of the tricycle, without the need for additional battery configuration.
[0029] Further, the three wheels and hand brake of the electric tricycle are not enough to provide sufficient stability. Two cylinder assemblies 110 are arranged on the body of the electric tricycle, and the cylinder assemblies are fixed on both sides of the electric tricycle. An auxiliary support is formed by air flow, and five-point support is formed together with the wheels, thereby improving the stability of the electric tricycle and having the effect of preventing overturning.
[0030] The embodiment is described in conjunction with the drawings in the specification Figure 1 to the drawings Figure 4 are described.
[0031] A stepped shell is formed at the rear hopper of the electric tricycle 100 by secondary welding processing, forming an access platform 120 for maintenance or auxiliary work. An air compressor is fixedly installed in the internal space of the shell. For easy maintenance, an access door 140 is arranged on the side of the shell. Opening the access door 140 allows the internal air compressor to be maintained. The air compressor uses the power battery of the electric tricycle as power and is configured with a compressed air storage tank for providing compressed gas to the spray gun. That is, the compressed air pipe is connected with the electromagnetic valve and the spray gun through the air path pipeline, thereby realizing the supply of gas to the spray gun.
[0032] Further, safety protection measures are arranged at the access platform 120 described above, such as welding or screwing a guardrail 121 on the side and front. When personnel climb, they can hold the guardrail or hang the hook of a safety harness on the guardrail.
[0033] Two of the above protective fences are extended upwards and form two mounting gantry support cylinders 122. The so-called gantry 130 refers to a structure composed of a cross beam 131 and two upright columns 132. The two upright columns of the gantry are inserted into the support cylinder, and a plurality of plug holes 123 are arranged between the insertion of the upright column and the support cylinder, and the effective height of the gantry 130 is adjusted by plug locking.
[0034] The gantry cross beam serves as a mounting carrier for the spraying and ultraviolet module. A rack and linear guide rail are mounted on the cross beam. A micro motor and a pinion are mounted in the spraying and ultraviolet module. The spraying and ultraviolet module is movably connected to the cross beam through the linear guide rail assembly and the gear rack mechanism. Under the drive of the micro motor, the spraying and ultraviolet module reciprocates along the Y-axis direction of the cross beam. When the micro motor is a high-precision micro servo motor, the Y-axis step of the spraying and ultraviolet module can be accurately controlled.
[0035] The spraying and ultraviolet module 200 includes a fixed frame 210, a vertical arm, a spray gun, an ultraviolet irradiation lamp, and a partition plate. The fixed frame and the cross beam are movably connected through the linear guide rail assembly and the gear rack mechanism, and the fixed frame 210 is driven to displace.
[0036] The fixed frame 210 is used to mount the vertical arm 220. The number of vertical arms 220 is two, and the two are arranged side by side. One is used to mount a spray gun, and the other is used to mount an ultraviolet irradiation lamp. A partition plate 230 is fixedly mounted on the fixed frame between the two vertical arms 220, and the partition plate 230 is centrally arranged between the two.
[0037] Similarly, the vertical arm and the fixed frame are movably connected through the linear guide rail assembly and the gear rack mechanism. The servo motor II for driving the vertical movement of the vertical arm is also fixed in the fixed frame 210, which is used to drive the vertical movement of the vertical arm. The vertical movement can fine-tune the height value of the paint spraying within a certain range.
[0038] A cantilever 240 is tightly fastened to the lowest end of the vertical arm 220 by a screw. The cantilever is a steel pipe, and the cantilever is used to mount a functional module.
[0039] Each vertical arm corresponds to a cantilever 240, and the two cantilevers exist independently relative to each other.
[0040] A spray gun 250 and an ultraviolet irradiation lamp 260 are respectively mounted on the two cantilevers, i.e., a spray gun is mounted at the end of one cantilever, and an ultraviolet irradiation lamp is mounted at the end of the other cantilever. The spray gun is used for spraying vehicle body marks, and the ultraviolet irradiation lamp is used for curing, so that the paint is quickly cured.
[0041] The space is isolated by setting the vertical partition 230 between the two, so as to prevent the ultraviolet lamp from damaging the nozzle in the spray gun, and meanwhile avoid the spray gun from affecting the ultraviolet irradiation lamp.
[0042] The spray gun 250 and the ultraviolet lamp 260 are electrically connected to the power battery of the electric vehicle, so that the device has a more compact structure.
[0043] Through the three-axis adjustment between the gantry, the vertical arm and the fixing frame, the spraying at the end of the cantilever and the ultraviolet module are close to the area to be sprayed on the vehicle body through the adjustment of three orientations.
[0044] For the selection of the spray gun: a digital spray gun is selected, through which, combined with digital programming, character type vehicle body marks can be directly sprayed out, or a common spray gun is selected, which needs to be matched with a hollow character template for character spraying.
[0045] The use method is as follows: the vehicle is driven to below the character spraying point, then the auxiliary support is provided through the cylinder assembly to improve the stability, the effective height of the gantry is adjusted so that the nozzle of the spray gun is located at the set height position, the paint spraying operation is started to form marks on the vehicle body, the characters are formed in a left-to-right manner, after the spraying is completed, the paint spraying is stopped, then the ultraviolet lamp is started, and the return reset of the fixing frame is started to quickly solidify the paint characters, the solidification speed is improved, and the paint spraying of a group of marks is completed.
[0046] The above-described embodiments are only used to describe the preferred embodiments of the utility model, and do not limit the scope of the utility model, and under the premise of not departing from the design spirit of the utility model, various deformations and improvements of the utility model by the related technicians in the field shall fall within the protection scope determined by the claim book of the utility model.
