For those skilled in the art, the specific meaning of the above terms in the embodiments can be understood according to the specific circumstances.

[0046] The related art is that the spraying work on the outer surface of the steel structure module box is usually performed by an operator holding a spraying gun and using a climbing aid tool such as a scaffold, which has a safety hazard of falling in high-altitude operation, and because the operation area is large, the climbing tool needs to be moved constantly, and the spraying efficiency is low. In order to solve the above technical defects, the embodiment of the utility model provides a lifting spraying mechanism for spraying the outer surface of a steel structure module box.

[0047] The embodiments of the utility model will be described below in combination with Figures 1 to 4 .

[0048] According to the embodiment of the utility model, a lifting spraying mechanism for spraying the outer surface of a steel structure module box is provided, which comprises a stand 100, the stand 100 is provided with a Z-axis moving assembly, the moving end of the Z-axis moving assembly is provided with an X-axis moving assembly, and the X-axis moving assembly is driven to move along the Z direction; the moving end of the X-axis moving assembly is provided with a spray gun 200, and the spray gun 200 is driven to move along the X direction; the spray gun 200 is used for spraying the outer surface of the steel structure module box. It can be understood that the X direction, Y direction and Z direction in the text refer to the X direction, Y direction and Z direction in Figure 1 , and the X direction, Y direction and Z direction are perpendicular to each other.

[0049] The lifting spraying mechanism of the embodiment is arranged in a cross shape on the stand 100, and the Z-axis moving assembly and the X-axis moving assembly are arranged, and the spray gun 200 is arranged at the moving end of the X-axis moving assembly, so that the spray gun 200 can be automatically controlled to move along the X direction and the Z direction relative to the outer surface of the steel structure module box, thereby realizing the spraying operation on the outer surface of the steel structure module box without the aid of climbing tools such as scaffolds, reducing the labor intensity of the operator, eliminating the safety hazard of falling in high-altitude operation of the operator, and improving the spraying efficiency.

[0050] The specific structure and distribution mode of the Z-axis moving assembly of the embodiment will be described in detail below.

[0051] As Figures 1 to 3As shown, in some embodiments, the Z-axis moving assembly includes a rack 310, a Z-direction guide rail 320, a mounting plate 330, and a first motor 340. Specifically, the rack 310 is arranged along the Z-direction on the stand 100, and the Z-direction guide rail 320 is arranged on one side of the rack 310 along the X-direction. The mounting plate 330 is arranged on the Z-direction guide rail 320 through a sliding block along the Z-direction, and the X-axis moving assembly is arranged on the mounting plate 330. The first motor 340 is fixedly connected to the mounting plate 330, and the output end of the first motor 340 is connected with a gear 350, which is engaged with the rack 310. The output end of the first motor 340 is engaged with the rack 310 through the gear 350, and the first motor 340 is connected with the mounting plate 330 as a whole. When the first motor 340 drives the gear 350 to rotate forward or reverse, the gear 350 can stably move up and down along the rack 310 due to the rack 310 being fixedly connected to the stand 100, so that the mounting plate 330 drives the X-axis moving assembly and the spray gun 200 to stably move up and down together under the guidance of the Z-direction guide rail 320, realizing automatic spraying operation on different height positions of the outer surface of the steel structure module box body, with high automation level.

[0052] In order to reduce the occupied space of the Z-axis moving assembly along the Z-direction, so that the X-axis moving assembly and the spray gun 200 driven by the stand 100 of the same height size have a larger displacement along the Z-direction, thereby adapting to the spraying operation of the outer surface of the steel structure module box body with larger height size. Specifically, the first motor 340 is arranged parallel to the Y-direction and connected to the mounting plate 330 through a fixing plate 341.

[0053] As shown, Figure 2 Specifically, a speed reducer 342 is arranged between the output end of the first motor 340 and the gear 350, and the speed reducer 342 amplifies the torque output by the first motor 340 and then transmits it to the gear 350, so that the gear 350 can drive the relatively heavy mounting plate 330, X-axis moving assembly and spray gun 200 to stably move up and down along the Z-direction.

[0054] As shown, Figure 1 and Figure 2 Specifically, a first drag chain 371 is arranged on the stand 100 along the Z-direction, and the first drag chain 371 is used for the cable of the Z-axis moving assembly to pass through and be bound. A first drag chain support 372 is arranged on the mounting plate 330, and the movable end of the first drag chain 371 is connected to the first drag chain support 372. When the mounting plate 330 moves along the Z-direction, the first drag chain 371 moves along the Z-direction synchronously with the first drag chain support 372, thereby protecting, storing and pulling the cable of the Z-axis moving assembly and improving the service life of the cable of the Z-axis moving assembly.

[0055] In order to improve the stability performance of the mounting plate 330 when rising to a high position and staying at the high position for spraying operation, as shown, Figure 1 andFigure 3 Specifically, two racks 310 are provided, positioned opposite each other along the X-direction. The meshing of the two racks 310 and the two gears 350 increases the meshing transmission area, enabling a more stable movement of the X-axis moving assembly and the spray gun 200 along with the mounting plate 330. This also ensures that the mounting plate 330 does not tilt when the mounting plate 330 remains in a high position and the X-axis moving assembly drives the spray gun 200 along the X-direction for spraying. More specifically, the stand 100 is configured as a gantry, with the two racks 310 mounted on two vertical beams of the gantry.

[0056] like Figure 1 As shown, specifically, a first limit switch 361 is provided at the upper end of the mounting plate 330 along the Z direction, and a first limit paddle 362 is provided at the upper end of the stand 100 at a position corresponding to the first limit switch 361. When the mounting plate 330 rises along the Z direction to the position where the first limit switch 361 contacts the first limit paddle 362, the first limit switch 361 is triggered and controls the first motor 340 to stop, preventing the mounting plate 330 from exceeding the operating limit and detaching from the stand 100, thereby providing safety assurance for the normal operation of the lifting spraying mechanism of this embodiment.

[0057] like Figure 1 Specifically, a first shock absorber 365 is provided at the upper end of the stand 100 along the Z direction, corresponding to the position of the mounting plate 330. When the first limit switch 361 is damaged and cannot be used normally, and the mounting plate 330 rises beyond the operating limit, the mounting plate 330 preferentially makes soft contact with the first shock absorber 365 to provide a buffer, thereby reducing damage to the lifting and spraying mechanism of this embodiment.

[0058] like Figure 1 As shown, specifically, a second limit switch 363 is provided at the lower end of the mounting plate 330 along the Z direction, and a second limit paddle 364 is provided at the lower end of the stand 100 at a position corresponding to the second limit switch 363. When the mounting plate 330 descends downward along the Z direction to the position where the second limit switch 363 contacts the second limit paddle 364, the second limit switch 363 is triggered and controls the first motor 340 to stop, preventing the mounting plate 330 from exceeding the operating limit and falling to the ground, thereby providing safety assurance for the normal operation of the lifting spraying mechanism of this embodiment.

[0059] like Figure 1 Specifically, a second shock absorber 366 is provided at the lower end of the stand 100 along the Z direction, corresponding to the position of the mounting plate 330. When the second limit switch 363 is damaged and cannot be used normally, and the mounting plate 330 descends beyond its operating limit, the mounting plate 330 preferentially comes into soft contact with the second shock absorber 366 to provide a buffer, thereby reducing damage to the lifting and spraying mechanism of this embodiment.

[0060] The above embodiment is only a preferred embodiment of the specific structure of the Z-axis moving assembly. In other embodiments, the Z-axis moving assembly can be set as one of an electric cylinder, a pneumatic cylinder, a linear motor, or a ball screw nut subassembly, and drives the X-axis moving assembly to move back and forth along the Z direction.

[0061] The relative positional relationship between the Z-axis moving assembly and the X-axis moving assembly of this embodiment, as well as the specific structure and distribution of the X-axis moving assembly are described in detail below.

[0062] like Figures 1 to 3 As shown, in some embodiments, the X-axis moving assembly includes an X-axis moving driver 410 disposed on the mounting plate 330. The X-axis moving driver 410 is provided with a first connecting plate 420 that moves along the X-direction, and the spray gun 200 is disposed on the first connecting plate 420. During the spraying operation on the outer surface of the steel structure module box, the spray gun 200 can be driven to move in the X-direction and the Z-direction by the X-axis moving driver 410 and the Z-axis moving assembly. That is, the spray gun 200 can be driven to move to any position on the outer surface of the steel structure module box perpendicular to the Y-direction, thereby enabling precise and uniform spraying operation on the outer surface of the steel structure module box perpendicular to the Y-direction, thereby improving the spraying quality and efficiency.

[0063] In a specific application, the X-axis moving driver 410 can be configured as an electric cylinder, a pneumatic cylinder, a linear motor, or a ball screw nut subassembly, and drives the first connecting plate 420 to move back and forth along the X direction.

[0064] like Figure 2 As shown, specifically, the mounting plate 330 is provided with a plurality of corner supports 331 on the side facing away from the stand 100 along the Y direction, preferably eight corner supports 331 are provided here, and the eight corner supports 331 are evenly spaced along the X direction, and the X-axis moving driver 410 is provided at the upper end of the eight corner supports 331. By adding an angle support 331 to support and install the X-axis moving driver 410, the projection of the X-axis moving driver 410 along the Y direction can be made to at least partially fall within the mounting plate 330, thereby reducing the space occupied by the X-axis moving component and the Z-axis moving component along the Z direction, so that the spray gun 200 can be driven to have a larger displacement along the Z direction on the stand 100 of the same height dimension, thereby adapting to the spraying operation of the outer surface of the steel structure module box with a larger height dimension; and the thickness of the mounting plate 330 can be reduced, that is, while meeting the connection strength of the X-axis moving driver 410 assembled on the mounting plate 330, the mounting plate 330 can be made lighter, thereby ensuring a smoother lifting and lowering movement under the meshing transmission action of the gear 350 and the rack 310.

[0065] like Figure 2 and Figure 3As shown, specifically, the corner support 331 is provided with a mounting piece 332, and a second drag chain 431 is arranged on the mounting piece 332 in the X direction, and is used for passing and binding the cables of the X-axis moving assembly. The first connecting plate 420 is provided with a second drag chain support 432, and the movable end of the second drag chain 431 is connected to the second drag chain support 432. When the first connecting plate 420 moves in the X direction, the second drag chain 431 moves synchronously in the X direction together with the second drag chain support 432, so as to protect, store and pull the cables of the X-axis moving assembly, and improve the service life of the cables of the X-axis moving assembly.

[0066] As shown in some embodiments, Figures 1 to 3 As shown, the Y-axis moving assembly is arranged between the X-axis moving assembly and the spray gun 200, and includes a Y-axis moving driver 510 arranged on the first connecting plate 420. The Y-axis moving driver 510 is arranged with a second connecting plate 520 moving in the Y direction, and the spray gun 200 is arranged on the second connecting plate 520. By additionally arranging the Y-axis moving assembly, the spray gun 200 can be driven to move in the X direction, the Y direction and the Z direction by the X-axis moving driver 410, the Y-axis moving driver 510 and the Z-axis moving assembly during the spraying operation on the outer side surface of the steel structure module box, so as to form a corrosion and rust prevention coating with different thicknesses on the outer side surface of the steel structure module box, and to perform the spraying operation on the outer side surface of the concave-convex structure of the steel structure module box.

[0067] In specific applications, the Y-axis moving driver 510 can be arranged as one of an electric cylinder, a pneumatic cylinder, a linear motor or a ball screw nut pair assembly, and drives the second connecting plate 520 to move reciprocally in the Y direction.

[0068] Specifically, the second connecting plate 520 is provided with a third drag chain support 532, and a third drag chain 531 is arranged on the third drag chain support 532 in the Y direction, and is used for passing and binding the cables of the Y-axis moving assembly. The movable end of the third drag chain 531 is connected to the third drag chain support 532. When the second connecting plate 520 moves in the Y direction, the third drag chain 531 moves synchronously in the Y direction together with the third drag chain support 532, so as to protect, store and pull the cables of the Y-axis moving assembly, and improve the service life of the cables of the Y-axis moving assembly.

[0069] As shown in some embodiments, Figure 3 Specifically, the second connecting plate 520 is connected with a spraying profile plate 220 through a connecting piece 210, the spraying profile plate 220 is arranged parallel to the Y direction, one end of the spraying profile plate 220 extends to the outside of the Y-axis moving driver 510, and the spray gun 200 is connected to the one end.

[0070] As shown in some embodiments, Figure 1 and Figure 4As shown, in some embodiments, the lifting spraying mechanism further comprises a ground rail 600 arranged along the X direction, the lower end of the stand 100 along the Z direction is provided with a walking driving assembly, the walking driving assembly is rollingly arranged on the ground rail 600, and the walking driving assembly is electrically connected with the controller; the lower end of the stand 100 along the Z direction is provided with a roller encoder 710, the roller encoder 710 is rollingly abutted against the upper surface of the ground rail 600, and the roller encoder 710 is electrically connected with the controller. The spraying stations of the at least two steel structure module boxes are communicated through the ground rail 600, and the stand 100 is rollingly arranged on the ground rail 600 through the walking driving assembly. In the process that the lifting spraying mechanism in the embodiment sprays the outer side surface of the steel structure module box located in one spraying station, the operator can place another steel structure module box to be sprayed at another idle spraying station at the same time, so that after the lifting spraying mechanism in the embodiment completes the spraying station, it is automatically moved along the ground rail 600 to the spraying station corresponding to another steel structure module box to be sprayed to perform spraying work, thereby saving the time for waiting for replacement of the steel structure module box in the middle and further improving the spraying efficiency. Meanwhile, the lower end of the stand 100 is provided with the roller encoder 710, when the stand 100 moves along the ground rail 600, the roller encoder 710 measures the movement amount of the stand 100 along the X direction and feeds back to the controller, so as to ensure that the stand 100 moves to align with the spraying station and the controller controls the walking driving assembly to stop accurately, thereby ensuring the quality of spraying.

[0071] It should be noted that the roller encoder 710 adopts an E6B2-CWZ1X rotary encoder sold on the market.

[0072] As shown in Figure 1 and Figure 4 , specifically, the walking driving assembly comprises a main walking wheel 720 and a slave walking wheel 730 arranged at the lower end of the stand 100, the main walking wheel 720 is driven to rotate by a second motor 740, and the second motor 740 is electrically connected with the controller. The slave walking wheel 730 is used for supporting and assisting the walking of the stand 100, the main walking wheel 720 is connected with the second motor 740, and the lifting spraying mechanism in the embodiment is automatically moved to align with the corresponding spraying station for spraying work according to the set walking track by adjusting the forward and reverse walking modes.

[0073] As shown in Figure 4 , specifically, the lower end of the stand 100 is provided with a third connecting plate 751, the third connecting plate 751 is provided with two guide wheels 752, the two guide wheels 752 are oppositely arranged along the Y direction and abut against the two sides of the ground rail 600 along the Y direction respectively. The two guide wheels 752 play a role of limiting and guiding, effectively avoiding side turning during the movement of the stand 100 along the X direction.

[0074] As shown in Figure 1As shown, specifically, a shock absorber 760 is provided on the side of the walking wheel 730 away from the main walking wheel 720 along the X direction. When there is an obstacle on the route of the walking wheel 730 moving away from the main walking wheel 720 along the X direction, the shock absorber 760 preferentially contacts the obstacle for buffering, thereby reducing damage to the lifting and spraying mechanism of this embodiment.

[0075] like Figure 1 As shown, specifically, a clamp 800 is provided at the lower end of the stand 100. The clamp 800 has a locked state in which it abuts against the two side walls of the floor rail 600 along the Y direction, and an unlocked state in which it is disengaged from the two side walls of the floor rail 600. When the stand 100 moves to a set position and stops, the clamp 800 is switched from the unlocked state to the locked state, thereby securing the stand 100 to the floor rail 600 and ensuring that the lifting spray mechanism of this embodiment does not easily slide relative to the floor rail 600 when spraying the outer surface of the steel structure module box.

[0076] Specifically, the clamp 800 includes two hydraulic rods arranged relative to the ground rail 600 along the Y direction, and the piston ends of the two hydraulic rods facing each other are provided with clamping parts; when the clamp 800 is in a locked state, the two clamping parts move closer to each other until they are tightly abutted against the two side walls of the ground rail 600 along the Y direction; when the clamp 800 is in an unlocked state, the two clamping parts move away from each other until they are disengaged from the two side walls of the ground rail 600.

[0077] In a specific application, the clamp 800 may also adopt a mature clamping system currently available on the market, such as the clamping system model YJJ250-P43 produced by Henan Zhongyuan Brake Co., Ltd.

[0078] Specifically, the lifting and spraying mechanism also includes a QR code, which is installed on the ground of the spraying station of the steel structure module box. The lower end of the stand 100 along the Z direction is provided with a visual detection unit, which is used to capture the QR code to obtain a first image, and transmit the first image to the controller. The controller obtains a stop signal and spraying data based on the first image. The controller controls the travel drive assembly to stop according to the stop signal and controls the movement of the Z-axis moving assembly, the X-axis moving assembly, and the Y-axis moving assembly according to the spraying data; ensuring that the lifting and spraying mechanism of this embodiment is accurately moved to a position aligned with the spraying station, and the spraying operation is performed according to the size of the outer surface of the corresponding steel structure module box. More specifically, the visual detection unit is configured as a CCD camera.
