DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] like Figure 1-Figure 3 As shown, the spraying vehicle according to the embodiment of the present invention includes a body 3 and a spraying assembly.

[0023] Specifically, the spraying assembly is arranged at the front end of the fuselage 3 and includes a first robotic arm 1 and a second robotic arm 2. The heads of the first robotic arm 1 and the second robotic arm 2 are both provided with spray guns 14, and the heads of the first robotic arm 1 and the second robotic arm 2 are movable in the up and down directions relative to the fuselage 3.

[0024] like Figure 1 As shown, walking parts 4 for driving the spraying vehicle to move are arranged on both sides of the fuselage 3, a pump station 5 and a gas tank 6 are arranged at the tail of the fuselage 3, a pump group 7, a material box 8 and a control cabinet 9 are arranged in the middle, and the spraying assembly is arranged at the head of the fuselage 3. It can be understood that the first mechanical arm 1 and the second mechanical arm 2 have freedom in the up and down directions, so that during the spraying operation, one of the two mechanical arms can carry a spray gun 14 to spray the upper side, and the other mechanical arm can carry a spray gun 14 to spray the lower side, that is, the dual mechanical arm design can spray the upper side and the lower side at the same time, thereby significantly improving the spraying efficiency.

[0025] The spraying vehicle of the embodiment of the present invention has a spraying assembly disposed at the front end of a fuselage 3 and the spraying assembly includes a first robotic arm 1 and a second robotic arm 2. The heads of the first robotic arm 1 and the second robotic arm 2 are both provided with spray guns 14, and the heads of the first robotic arm 1 and the second robotic arm 2 are movable in the up and down directions relative to the fuselage 3. Thus, the two independent robotic arms have freedom of movement in the up and down directions, so that the spray guns 14 can be carried to spray the sides of the tunnel at different heights at the same time, and there is no need to adjust the height of the equipment to perform multiple spraying operations, and the spraying efficiency is high.

[0026] Furthermore, the control systems, spray pumps, material boxes 8 and connecting pipes equipped in the first robot arm 1 and the second robot arm 2 are independent of each other, and the two robot arms will not affect or interfere with each other when they move simultaneously.

[0027] Furthermore, the first robot arm 1 and the second robot arm 2 are arranged at intervals in the width direction of the fuselage 3. Therefore, on the one hand, there is a sufficient safety distance between the two robot arms, and there will be no structural interference when the robot arms are operating. On the other hand, the two robot arms are arranged at intervals in the width direction of the fuselage 3 to increase the maximum spraying width. For example, when two robot arms are used to spray the upper part at the same time, the maximum spraying width is the sum of the spraying widths of the two robot arms, and the spraying efficiency is high.

[0028] Furthermore, if Figure 3 As shown, the first robot arm 1 and the second robot arm 2 both include a lifting joint 10 and a cantilever joint, the lifting joint 10 is connected to the fuselage 3 and can be extended in the up and down direction, one end of the cantilever joint is connected to the lifting joint 10, and the other end is connected to the spray gun 14. Therefore, the extension and retraction of the lifting joint 10 can ultimately drive the spray gun 14 to move in the up and down direction to achieve spraying of different height areas.

[0029] Optionally, the lifting joint 10 may be a hydraulic lifting cylinder.

[0030] Furthermore, the cantilever joint can rotate in a vertical plane relative to the lifting joint 10. Thus, the lifting joint 10 can provide a degree of freedom of movement in the up-down direction, while the cantilever joint can provide a degree of freedom of rotation in the vertical plane. After the lifting joint 10 drives the spray gun 14 to the working height, the height of the spray gun 14 can be further adjusted within the working area by swinging the cantilever joint, so as to perform mobile spraying in a small range and improve the control accuracy of the position of the spray gun 14.

[0031] Furthermore, the cantilever joint can swing up to 150° with 0° being vertically upward.

[0032] Furthermore, if Figure 3 As shown, the cantilever joint includes a telescopic joint 11, and the two ends of the telescopic joint 11 are respectively connected to the lifting joint 10 and the spray gun 14, and the telescopic joint 11 is telescopic. Therefore, the telescopic joint 11 can drive the spray gun 14 to extend forward or backward, so that the spray gun 14 has a flexible spraying distance. It should be noted that the side surfaces at different positions of the lane have undulations or sections, which may result in different distances between the side surfaces at different positions and the spray head vehicle. At this time, the telescopic joint 11 can be used to flexibly adjust the extension distance of the spray gun 14, so that effective spraying can be performed on the side surfaces at different distances.

[0033] Furthermore, if Figure 3As shown, the cantilever joint also includes a first rotating joint 12, the telescopic joint 11 is connected between the lifting joint 10 and the first rotating joint 12, the first rotating joint 12 is rotatable around a first axis in a vertical plane relative to the telescopic joint 11, and the spray gun 14 is connected to the first rotating joint 12. In other words, the first rotating joint 12 can provide a small degree of rotation freedom for the spray gun 14 in the vertical plane to adjust the pitch angle of the spray gun 14, ensuring that the spray gun 14 is always perpendicular to the spraying surface.

[0034] Furthermore, if Figure 3 As shown, the cantilever further includes a second rotary joint 13, which is connected to the first rotary joint 12, and the second rotary joint 13 is rotatable relative to the first rotary joint 12 around a second axis, the second axis is perpendicular to the extension direction of the telescopic joint 11 and the first axis, and the spray gun 14 is connected to the end of the second rotary joint 13. In other words, the second rotary joint 13 can rotate around the y-axis so that the spray gun 14 can swing and spray within a certain width area.

[0035] Specifically, the rotation angle of the second rotation joint 13 can reach plus or minus 60 degrees, and the width of the spraying coverage in one continuous operation can reach 1 meter in the X direction.

[0036] Furthermore, a protective plate 15 is also provided on the second rotating joint 13 , and the protective plate 15 and the spray gun 14 move synchronously with the second rotating joint 13 , which can effectively control the splashing range of the spraying material.

[0037] In some embodiments, the lifting joint 10 is provided with an L plate 16, the L plate 16 includes a mounting plate parallel to the lifting joint 10, the cantilever joint is installed on the end surface of the mounting plate away from the lifting joint 10, the mounting plate is provided with a plurality of spaced connection holes 17, the plurality of connection holes 17 are distributed in a ring shape, the cantilever joint is provided with a plurality of fixing holes corresponding to the connection holes 17, and the fixing holes are connected to the connection holes 17 by bolts. Figure 2 As shown, the mounting plate is provided with eight connection holes 17, and the eight bolt holes form a circular band. The cantilever joint can rotate at a large angle after being fixed on the L plate 16 by bolts.

[0038] Furthermore, a reinforcing rib is provided on the side of the L-plate 16 facing the lifting joint 10 to increase the structural strength of the L-plate 16 .
