DETAILED DESCRIPTION

[0020] See also Figure 1-4The utility model provides a sliding automatic painting device for the bottom of a steel structure bridge, comprising a moving car 1, a material storage barrel 2 and a pump body 3. The material storage barrel 2 is fixed at one end of the top surface of the moving car 1, and the pump body 3 is installed on the top surface of the moving car 1 on one side of the material storage barrel 2. The feed pipe of the pump body 3 is connected to the inside of the material storage barrel 2. An opening 4 is penetrated at the middle position of the moving car 1, and conflict grooves 5 are communicated at both ends of the opening 4. A moving seat 6 is penetrated and inserted at the middle position of the opening 4, and a movable rod 10 arranged in an L shape is penetrated and inserted on one side of the moving seat 6. A spraying pipe 11 is fixed at one end of the movable rod 10, and a sliding seat 7 is slidably inserted in the inside of the conflict groove 5. The sliding seat 7 is close to the moving car 1 at one end thereof. The surfaces at both ends of the moving seat 6 are fixed, and a first threaded rod 8 is threadedly connected through the middle position of one of the sliding seats 7. The moving seat 6 is fixed to the side of the moving vehicle 1 away from the pump body 3, and one side of the first threaded rod 8 is rotatably connected to the inner wall of the adjacent position abutting groove 5. The other side of the first threaded rod 8 passes through the moving vehicle 1 and is fixed to the output end of the first threaded rod 8. By pushing the moving vehicle 1 to the side of the bridge and starting the first threaded rod 8, the spray pipe 11 can be extended to the bottom of the bridge, and then the paint is discharged from the discharge pipe of the spray pipe 11 from the pump body 3, so that the bottom of the bridge can be painted, and the bottom of the bridge can be gradually painted along the trajectory of the moving vehicle 1.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that a storage port 12 is provided through the surface of the sports seat 6, a second threaded rod 13 is rotatably connected inside the storage port 12, a threaded sleeve 14 is threadedly connected to the outer circumference of the second threaded rod 13, one side of the second threaded rod 13 passes through the sports seat 6 and extends to a position close to one side of the sports vehicle 1, a sleeve block 15 is sleeved on the outer circumference of the movable rod 10, an annular groove 23 is provided inside the sleeve block 15, a limiting ring 24 is slidably inserted inside the annular groove 23, the inner circumference of the limiting ring 24 is fixed to the outer circumference of the movable rod 10, and the top of the threaded sleeve 14 is hinged with a connection Rod 16, one side of the connecting rod 16 is hinged to the surface of the sleeve block 15. Since the inner cavity of the storage port 12 can play a role of resisting and limiting the threaded sleeve 14, when the second threaded rod 13 is rotated, the threaded sleeve 14 can move in the horizontal direction under the cooperation between the internal thread structure of the inner wall of the threaded sleeve 14 and the external thread structure of the outer peripheral surface of the second threaded rod 13, so that the connecting rod 16 can change its angle, thereby driving the sleeve block 15 to move in the vertical direction, so that the movable rod 10 can move in the vertical direction under the resistance between 25 and the limit ring 24.

[0022] Further as Figure 3As shown, it is worth specifically explaining that a second motor 18 is fixed to the bottom of the surface of the side of the sports seat 6 away from the sports car 1, and the output end of the second motor 18 extends to a position close to the sleeve block 15. An incomplete gear 17 is fixedly sleeved on the outer circumferential surface of the movable rod 10 at a position located at the bottom of the sleeve block 15, and a first circular gear 19 is fixedly sleeved on the output end of the second motor 18 near the incomplete gear 17. The incomplete gear 17 and the first circular gear 19 are meshingly connected. A second circular gear 20 is fixedly sleeved on the outer circumferential surface of the movable rod 10 at a position located at the bottom of the incomplete gear 17. A rack 21 is meshingly provided at one end of the second circular gear 20, and a spring telescopic rod 22 is fixed to one side of the rack 21, and one side of the spring telescopic rod 22 is fixed to the surface of the sports seat 6. When the second motor 18 is started, the first circular gear 19 can rotate, thereby making the second circular gear 20 A circular gear 19 can mesh with the incomplete gear 17 to drive the movable rod 10 to rotate, and when the incomplete gear 17 is separated from the first circular gear 19, the movable rod 10 will not be subjected to the rotational force applied by the first circular gear 19. When the movable rod 10 rotates, it can drive the second circular gear 20 to rotate, so that the second circular gear 20 drives the rack 21 to move in the horizontal direction and contact the spring telescopic rod 22 at the adjacent position to cause it to deform, so that when the first circular gear 19 is separated from the incomplete gear 17, the rack 21 can slide in the opposite direction and mesh with the second circular gear 20 at the adjacent position under the action of the rebound force of the spring telescopic rod 22, so that the movable rod 10 is reset so that the first circular gear 19 can mesh with the incomplete gear 17 again, thereby realizing the reciprocating swing of the movable rod 10 along a certain angle.

[0023] This solution has the following working process: in actual use, when the user needs to spray paint the bottom of the bridge, the discharge pipe of the pump body 3 is connected to the feed pipe of the spray pipe 11 through a rubber hose, so that when the pump body 3 is started, the paint inside the storage barrel 2 can be transported to the inside of the spray pipe 11, and then the sports car 1 is pushed to the side of the bridge, so that the sports seat 6 and the spray pipe 11 can extend to one side of the bridge, and by starting the first threaded rod 8, due to The inner cavity of the resistance groove 5 can play a role of resistance limitation on the sliding seat 7, so that the sliding seat 7 can drive the moving seat 6 to move horizontally to the depth of the opening 4 under the cooperation between the internal thread structure of the inner wall of the sliding seat 7 and the external thread structure of the outer peripheral surface of the first threaded rod 8, so that the moving seat 6 can drive the spray pipe 11 to move to the resistance of the bridge, so that the paint discharged from the discharge port of the spray pipe 11 can be sprayed to the bottom of the bridge, and the moving vehicle 1 is gradually pushed intermittently, so that the bottom of the bridge can be sprayed step by step along the trajectory of the moving vehicle 1. The paint treatment improves the efficiency of the painting operation. When the sports car 1 is stationary, the second motor 18 is started to enable the first circular gear 19 to rotate, so that the first circular gear 19 can mesh with the incomplete gear 17 to drive the movable rod 10 to rotate, and when the incomplete gear 17 is separated from the first circular gear 19, the movable rod 10 will not be subjected to the rotational force applied by the first circular gear 19. When the movable rod 10 rotates, the second circular gear 20 can be driven to rotate, so that the second circular gear 20 drives the rack 21 to move in the horizontal direction against the spring telescopic rod 22 at the adjacent position to deform it, so that when the first circular gear 19 is separated from the incomplete gear 17, under the action of the rebound force of the spring telescopic rod 22, the rack 21 can slide in the opposite direction and mesh with the second circular gear 20 at the adjacent position, so that the movable rod 10 is reset so that the first circular gear 19 can mesh with the incomplete gear 17 again, thereby enabling the movable rod 10 to swing back and forth along a certain angle, thereby expanding the painting range of the spray pipe 11 when the sports car 1 is stationary.

[0024] According to the above working process, it can be known that: by pushing the moving vehicle 1 to the side of the bridge and starting the first threaded rod 8 so that the spray pipe 11 can extend to the bottom of the bridge, and then discharging the paint from the discharge pipe of the spray pipe 11 from the pump body 3, the bottom of the bridge can be sprayed with paint, and the bottom of the bridge can be gradually sprayed with paint along the trajectory pushed by the moving vehicle 1, thereby improving the efficiency of the painting operation, and making the painting operation safe and convenient, thereby improving the practicality of the device, and starting the second motor 18 so that the first circular gear 19 can mesh with the incomplete gear 17, and rotating the movable rod 10 can make the rack 21 resist the spring telescopic rod 22 and deform, so that under the action of the rebound force of the spring telescopic rod 22, the incomplete gear 17 can intermittently mesh with the first circular gear 19, so that the movable rod 10 can drive the spray pipe 11 to swing back and forth at a certain angle, thereby expanding the painting range of the spray pipe 11 when the moving vehicle 1 is stationary, thereby further improving the practicality of the device.

[0025] Further as Figure 4 As shown, it is worth explaining in detail that a limit rod 9 is slidably inserted through the middle position of another sliding seat 7, and both sides of the limit rod 9 are fixed to both sides of the inner wall of the adjacent position abutting groove 5. The sliding seat 7 can only slide on the outer peripheral surface of the limit rod 9 in the inner cavity of the adjacent position opening 4, thereby further limiting the movement trajectory of the moving seat 6, so that the moving seat 6 can move more smoothly in the horizontal direction.

[0026] In summary: by pushing the moving vehicle 1 to the side of the bridge and starting the first threaded rod 8 so that the spray pipe 11 can extend to the bottom of the bridge, and then by discharging the paint from the discharge pipe of the spray pipe 11 from the pump body 3, the bottom of the bridge can be sprayed with paint, and the bottom of the bridge can be gradually sprayed with paint along the trajectory pushed by the moving vehicle 1, thereby improving the efficiency of the painting operation, and making the painting operation safe and convenient, thereby improving the practicality of the device, by starting the second motor 18 so that the first circular gear 19 can mesh with the incomplete gear 17, and by rotating the movable rod 10, the gear can be meshed with the incomplete gear 17. The strip 21 is deformed by contacting the spring telescopic rod 22, so that the incomplete gear 17 can intermittently mesh with the first circular gear 19 under the action of the rebound force of the spring telescopic rod 22, so that the movable rod 10 can drive the spray pipe 11 to swing back and forth at a certain angle, thereby expanding the spraying range of the spray pipe 11 when the moving vehicle 1 is stationary, thereby further improving the practicality of the device. The sliding seat 7 can only slide on the outer peripheral surface of the limit rod 9 in the inner cavity of the adjacent position opening 4, thereby further limiting the movement trajectory of the moving seat 6, so that the moving seat 6 can move more smoothly in the horizontal direction.

[0027] The first threaded rod 8 and the second motor 18 can be purchased on the market. The first threaded rod 8 and the second motor 18 are equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
