DETAILED DESCRIPTION

[0021] The 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 sprayable anchor truck according to the embodiment of the present invention includes a body 1 , an anchor protection assembly and a spray assembly 3 .

[0023] Specifically, the anchor guard assembly includes a plurality of drills 2 arranged at intervals in the width direction of the fuselage, the spray assembly 3 includes a mechanical arm 5, a spray gun 9 and a protective member 4, the mechanical arm 5 is mounted on the fuselage 1 and its free end is connected to the spray gun 9, the protective member 4 includes a protective plate and a retractable telescopic cylinder, the telescopic cylinder is connected to the fuselage 1 and its top end is connected to the protective plate, and the top plate is located above the spray assembly 3.

[0024] It can be understood that the sprayable anchor truck of the present application integrates an anchor protection component and a spraying component 3 on the fuselage 1 at the same time. The anchor protection component uses a drilling rig 2 to anchor the tunnel, and the spraying component 3 uses a robotic arm to drive a spray gun 9 to spray the side of the tunnel. Support and spraying can be performed in one operation without the need for equipment alternation, saving construction time.

[0025] In addition, before the spraying operation, the telescopic cylinder can be used to drive the protective plate to move upward so that the protective plate blocks the top of the spraying component 3, thereby preventing the falling gangue from colliding with the robotic arm 5 and protecting the spraying component 3.

[0026] The sprayable anchor truck of the embodiment of the present invention has an anchor protection assembly and a spraying assembly 3 on the fuselage 1, the anchor protection bracket can drive the protective plate to move and support the tunnel, the mechanical arm 5 can drive the spray gun 9 to spray the side of the tunnel at the same time, the protective part 4 includes a protective plate and a retractable telescopic oil cylinder, the telescopic oil cylinder is connected to the fuselage 1 and its top is connected to the protective plate, and the top plate is located above the spraying assembly 3. Therefore, the sprayable anchor truck of the present application can realize the integrated operation of support and spraying, without the need for equipment alternating operation, and has high construction efficiency, and the protective part 4 can shield and protect the spraying assembly 3 to prevent the falling of gangue from damaging the mechanical arm 5.

[0027] Further, if Figure 1 As shown, the protective element 4 and the spray assembly 3 are centrally arranged at the head of the fuselage 1, the structural layout has a high degree of integration, the space utilization rate of the fuselage 1 is high, and the protective element 4 can realize nearby protection.

[0028] In some embodiments, as Figure 3 As shown, the telescopic cylinders include a first telescopic cylinder 10 and a second telescopic cylinder 11 spaced apart across the width of the fuselage 1. The protective plate is connected to both the first and second telescopic cylinders 10, 11. In other words, with a telescopic cylinder positioned on each side of the protective plate, the plate's movement is more stable, and the two telescopic cylinders provide more stable and balanced support, resulting in a better support effect.

[0029] Further, if Figure 3 As shown, the protective plate includes a main body 13 and a folding plate 14. The main body 13 is connected to the first telescopic cylinder 10 and the second telescopic cylinder 11. The folding plate 14 is connected to one side of the main body 13 and can be flipped relative to the main body 13. Therefore, before the spraying operation, the telescopic cylinder can be extended to drive the protective plate upward. After the protective plate is raised into position, the folding plate 14 can be flipped to a horizontal position to form a large support surface with the main body 13, improving the support effect. When the telescopic cylinder is lowered to release the protective plate from the top support state, the folding plate 14 can be rotated and retracted, reducing the size of the equipment.

[0030] It should be noted that before the spraying operation, the telescopic cylinder can support the protective plate on the top surface of the tunnel. It can use the reaction force of the support to stabilize the anchor truck to prevent shaking, and it can also directly support the top surface of the tunnel to prevent the gangue from falling.

[0031] Further, if Figure 3 As shown, the first telescopic cylinder 10 and the second telescopic cylinder 11 each include a telescopic rod, the top end of which is connected to the protective plate. An extension cylinder 12 is hingedly connected to one end of the telescopic rod below the protective plate. The outer end of the extension cylinder 12 is hingedly connected to the folding plate 14. Thus, extending the extension cylinder 12 drives the folding plate 14 to flip and unfold, while retracting the extension cylinder 12 drives the folding plate 14 to flip and fold. This makes operation simple and reliable.

[0032] Further, if Figure 3 As shown, the main body 13 is connected to a first folding plate 14 and a second folding plate 14 on either side of the fuselage 1 in the width direction. The first telescopic cylinder 10 and the first folding plate 14 are located on the same side, with the first extension cylinder 12 connected between them. The second telescopic cylinder 11 and the second folding plate 14 are located on the same side, with the second extension cylinder 12 connected between them. In other words, the protective plate is composed of the central body 13 and the two folding plates 14. Compared to a folding plate 14 on one side, the two folding plates 14 provide a larger protective area when deployed, while also not taking up space when retracted.

[0033] In some embodiments, as Figure 1 As shown, the robotic arms 5 include a first robotic arm 5 and a second robotic arm 5 spaced apart in the width direction of the fuselage 1. The first robotic arm 5 is located on the side of the first telescopic cylinder 10 facing away from the second telescopic cylinder 11, and the second robotic arm 5 is located on the side of the second telescopic cylinder 11 facing away from the first telescopic cylinder 10. Thus, the two robotic arms 5 can operate independently and simultaneously spray parts at different heights, achieving high operating efficiency.

[0034] Further, if Figure 2 As shown, the robot arm 5 includes a lifting joint and a retractable cantilever joint 6. One end of the lifting joint is connected to the fuselage 1, and the other end is connected to the cantilever joint 6. The lifting joint is retractable in the up and down directions. The outer end of the cantilever joint 6 is connected to the spray gun 9, and the cantilever joint 6 is rotatable in the vertical plane relative to the lifting joint. As a result, the lifting joint can drive the spray gun 9 to move up and down so as to spray working areas at different heights. The rotation of the cantilever joint 6 can further adjust the precise position and angle of the spray gun 9. In addition, the side surfaces at different positions in the roadway have undulations or cross-sections, which may result in different distances between the side surfaces at different positions and the spray head vehicle. At this time, the retractability of the cantilever joint 6 can flexibly adjust the extension distance of the spray gun 9, so that the side surfaces at different distances can be effectively sprayed.

[0035] Further, if Figure 2 As shown, the outer end of the cantilever joint 6 is connected to a first rotary joint 7. The first rotary joint 7 is rotatable about a first axis in a vertical plane relative to the cantilever joint 6. The spray gun 9 is connected to the first rotary joint 7. In other words, the first rotary joint 7 provides the spray gun 9 with a small degree of rotational freedom in the vertical plane, thereby enabling adjustment of the pitch angle of the spray gun 9 and ensuring that the spray gun 9 is always perpendicular to the spraying surface.

[0036] Further, if Figure 2As shown, the outer end of the first rotary joint 7 is connected to the second rotary joint 8. The second rotary joint 8 is rotatable relative to the first rotary joint 7 about a second axis. The second axis is perpendicular to the extension direction of the first rotary joint 7 and the first axis. The spray gun 9 is connected to one end of the second rotary joint 8. In other words, the second rotary joint 8 can rotate about the y-axis, so that the spray gun 9 can swing and spray within a certain width area.

[0037] Specifically, the rotation angle of the second rotary joint 8 can reach plus or minus 60 degrees, and the spray coverage width of one continuous operation can reach 1 meter in the X direction.
