Description

TECHNICAL FIELD

[0001] The utility model relates to tower paint maintenance technical field especially relates to a wind power tower automatic paint spraying device. BACKGROUND

[0002] In the long-term use process of the wind power tower, the tower wall surface is easily affected by the natural environment and produces different degrees of wear and corrosion, such as the action of rain, dust and wind force, which can cause scratches or local corrosion on the tower wall, and further reduce the overall structural strength and service life of the tower. Traditionally, the maintenance of the wind power tower mainly relies on manual climbing for painting repair. However, due to the high height of the wind power tower, manual operation not only has great safety risk, but also leads to low repair efficiency due to increased operation difficulty, which cannot meet the needs of timely repair.

[0003] At present, there are some automatic paint spraying devices for wind power towers on the market, which usually realize automatic climbing and paint spraying operation through walking motors. However, the design of the existing devices has the following main problems: first, the diameter of the wind power tower decreases from bottom to top, and the existing walking motor structure cannot adapt to the change of the tower diameter, resulting in the device cannot continue to climb stably at the upper part of the tower; second, the paint spraying device has poor fixing effect during spraying, which can cause uneven spraying due to position deviation. In view of these technical defects, an automatic paint spraying device for wind power tower is needed, which can automatically adapt to the change of the diameter of the wind power tower. SUMMARY

[0004] The utility model provides a kind of wind power tower automatic paint spraying device to solve the above technical problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A kind of wind power tower automatic paint spraying device, including tower body, traction support and drive traction equipment, the traction support is fixedly installed on the top of tower body, the traction support is equipped with guide wheel, the drive traction equipment is slidably connected with guide wheel by traction cable, further including hoisting limiting component, the hoisting limiting component includes movable sleeve ring and a plurality of limiting rods, the movable sleeve ring is sleeved on the tower body, the plurality of limiting rods are horizontally through the side wall of movable sleeve ring at equal intervals, the inner chamber of movable sleeve ring is provided with a plurality of drive motors corresponding to limiting rod, the limiting rod and drive motor are cooperated and move horizontally, the inner wall of movable sleeve ring is provided with chromatic aberration detector, the top of movable sleeve ring is provided with slide rail in circumferential direction, the paint spraying assembly is slidably connected on the slide rail, the free end of traction cable is connected with hoisting limiting component.

[0007] Further, the paint spraying assembly comprises a paint spraying box and a spraying nozzle, and the paint spraying box is provided with a feeding opening at the top, and the spraying nozzle is arranged on the side of the paint spraying box facing the inner wall of the movable sleeve. The spraying nozzle is arranged on the side of the paint spraying box facing the inner wall of the movable sleeve, so that the spraying angle can be accurately aligned with the surface of the tower body, and the paint can be uniformly covered on the surface of the tower body, avoiding the problems of deviation and uneven coating.

[0008] Further, the bottom of the paint spraying box is provided with a driving pulley, and the spraying nozzle is arranged at the center of the bottom of the paint spraying box. The paint spraying box can slide along the slide rail around the movable sleeve, facilitating the no-dead-angle moving spraying on the surface of the tower body, and achieving the requirement of completely covering the surface of the tower body. The spraying nozzle arranged at the center of the bottom can ensure that the spraying operation can be fully performed when there is less paint in the paint spraying box.

[0009] Further, the movable sleeve is provided with a control system for controlling the driving motor, the spraying nozzle and the driving pulley. The horizontal movement of the limiting rods can be controlled through the driving motor. When the movable sleeve moves upward in the vertical direction, the outer diameter of the tower body gradually decreases, at this time, the limiting rods all move towards the movable sleeve, the distance between the limiting rods is reduced, and the movable sleeve is in a stable fixing effect. When the movable sleeve moves downward, the outer diameter of the tower body increases, at this time, the limiting rods all move outward, the fixing diameter of the movable sleeve is increased, so as to ensure that the movable sleeve is always closely attached to the surface of the tower body. Through the feedback of the color difference detector, the control system can detect the slight change of the coating color and judge the spraying quality in real time. Once the color difference is detected, the control system can control the driving pulley to move to the corresponding position, and then adjust the spraying amount of the spraying nozzle, so as to ensure the consistency of the coating color. It should be noted that, in order to avoid the influence of the hoisting limiting assembly on the painted surface of the tower body, the hoisting limiting assembly is first lifted to the top of the tower body, and then moves downward for spraying operation. After the color difference detector detects the color difference change, the position information is recorded through the control system, and the spraying is performed when the spraying assembly moves down to the position. This design can perform spraying operation on the upper end of the spraying assembly when the color difference detector detects the lower end, which can reduce the waiting time of the equipment and improve the spraying efficiency.

[0010] Further, the top of both ends of the paint spraying box is provided with a suspension assembly, and the free end of the traction cable is connected with the suspension assembly. The suspension assembly stably suspends the paint spraying box above the movable sleeve through the traction cable, so that the paint spraying box can always keep balance, reducing the unstable factors caused by shaking during operation.

[0011] Further, any one set of the limiting rod comprises two independently arranged limiting rods, and the two independently arranged limiting rods are controlled by the same driving motor, and the end of the limiting rod towards the inner side of the movable ring is provided with a pressing block. The design of two independently arranged limiting rods can improve stability and avoid dislocation or insufficient support of a single limiting rod due to changes in the tower body.

[0012] Further, the pressing block is in an arc structure, and the outer end surface of the pressing block is provided with an anti-skid surface. The arc-shaped pressing block can better fit the surface of the tower, further increasing the gripping effect of the limiting rod and preventing the movable ring from sliding or deviating on the tower body. The pressing block effectively offsets the horizontal sliding force that may be generated during the painting process through its friction force, ensuring that the device can be stably fixed in different operating positions.

[0013] Further, the outer wall of the limiting rod is provided with a clamping tooth structure in the axial direction, and the driving motor is engaged with the clamping tooth structure through a rotating gear. The clamping tooth structure is arranged in the axial direction and cooperates with the rotating gear of the driving motor to realize accurate extension and position locking of the limiting rod. The gear engagement structure can push the limiting rod to extend or retract to a specified position under the instruction of the control system, ensuring the adjustment accuracy of the limiting rod and avoiding accidental sliding or position deviation of the limiting rod during operation.

[0014] Further, the color difference detector is provided with a plurality of color difference detectors arranged at equal intervals. The plurality of color difference detectors are arranged at equal intervals on the inner wall of the movable ring, which can monitor the color change of the tower surface in real time during the painting process. The spraying can be automatically compensated during the spraying process to ensure the uniformity and coverage of the paint layer.

[0015] Further, the inner diameter of the movable ring is greater than the outer diameter of the bottom of the tower body. Since the shape of the tower body is usually gradually narrowed from the bottom to the top, designing the inner diameter of the movable ring to be greater than the outer diameter of the bottom of the tower body helps the movable ring to move between different positions of the tower, ensuring that the painting device can smoothly perform the spraying operation at any height of the tower body.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model discloses a traction support, a movable ring and a limiting rod with a driving motor are arranged on the device, so that the device can be flexibly adjusted according to the diameter change of the wind power tower, ensuring stable climbing of the device at different heights of the tower, and overcoming the problem that the traditional walking motor device is limited in climbing the upper part of the tower.

[0018] 2. The utility model discloses a plurality of point support of limiting rod and real -time monitoring of color difference detector can ensure that the paint spraying assembly carries out the spraying operation, and promotes the spraying uniformity, avoids the problem of uneven spraying caused by the device deviation or vibration;

[0019] 3. The utility model discloses high security, convenient operation realizes the automatic lifting and spraying of equipment through traction cable and drive traction equipment cooperation, reduces the dependence on artificial climbing, reduces construction risk, simultaneously, the control system that sets up can carry out the automation control to limiting rod, spraying nozzle and pulley, simplifies the operation process, improves maintenance efficiency.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model is further explained in detail below with examples and drawings, and the illustrative embodiment and the explanation of the utility model are only used to explain the utility model, and do not limit the utility model.

[0025] Example one, as Figs. 1-3The utility model discloses a kind of automatic paint spraying devices of wind power tower, including tower body 1, traction support 2 and driving traction equipment 3, the traction support 2 is fixedly installed on the top of tower body 1, the traction support 2 is equipped with guide wheel 4, the driving traction equipment 3 is slidably connected with guide wheel 4 by traction cable 5, further including hoisting limiting component, the hoisting limiting component includes movable collar 6 and a plurality of limiting rods 7 that are sleeved on tower body 1, a plurality of limiting rods 7 are equidistantly horizontally penetrated through the side wall of movable collar 6, the inner chamber of movable collar 6 is provided with a plurality of drive motors 8 corresponding with limiting rod 7, limiting rod 7 and drive motor 8 are cooperated and do horizontal axial motion, the inner wall of movable collar 6 is provided with chromatic aberration detector 9, the top of movable collar 6 is circumferentially provided with slide rail 10, spray assembly is slidably connected on slide rail 10, the free end of traction cable 5 is connected with hoisting limiting component.

[0026] The spray assembly includes paint spraying box 11 and spraying nozzle 12, the top of paint spraying box 11 is provided with feeding port 13, and spraying nozzle 12 is arranged on the side of paint spraying box 11 facing the inner wall of movable collar 6. Specifically, spraying nozzle 12 is arranged on the side of paint spraying box 11 facing the inner wall of movable collar 6, which can ensure that the spraying angle is accurately aligned with the surface of tower body 1, so that the paint is evenly covered on the surface of tower body 1, and the conditions of spraying deviation or uneven coating are avoided. When preparing for spraying, paint is replenished in advance through feeding port 13 to ensure the demand of large-area spraying of tower body 1.

[0027] The bottom of paint spraying box 11 is provided with a driving pulley, and spraying nozzle 12 is located at the bottom center of paint spraying box 11. Specifically, paint spraying box 11 can slide around movable collar 6 along slide rail 10, which facilitates no-dead-angle moving spraying on the surface of tower body 1, and meets the requirement of completely covering the surface of tower body 1. Spraying nozzle 12 arranged at the bottom center can ensure that spraying operation can still be fully performed when there is less paint in paint spraying box 11.

[0028] The control system is arranged in the movable sleeve ring 6 for controlling the driving motor 8, the spraying nozzle 12 and the driving pulley. Specifically, the horizontal movement of the limiting rods 7 can be controlled by the driving motor 8. When the movable sleeve ring 6 moves upward in the vertical direction, the outer diameter of the tower body 1 gradually decreases, at this time, the limiting rods 7 all move inward to the movable sleeve ring 6, the distance between the limiting rods 7 is reduced, and then the movable sleeve ring 6 is in stable fixing effect. When the movable sleeve ring 6 moves downward, the outer diameter of the tower body 1 increases, at this time, the limiting rods 7 all move outward, the fixing diameter of the movable sleeve ring 6 is increased, so as to ensure that the movable sleeve ring 6 is always close to the surface of the tower body 1. Through the feedback of the chromatic aberration detector 9, the control system can detect the slight change of the coating color and judge the spraying quality in real time. Once the chromatic aberration is detected, the control system can control the driving pulley to move to the corresponding position, and then adjust the spraying amount of the spraying nozzle 12, so as to ensure that the color of the coating is consistent. It should be noted that, in order to avoid the influence of the hoisting limiting assembly on the surface of the tower body 1 which has been painted, the hoisting limiting assembly is first lifted to the top of the tower body 1, and then moves downward for spraying operation. After the chromatic aberration detector 9 detects the change of the chromatic aberration, the position information is recorded through the control system, and when the spraying assembly moves to the position, the spraying is carried out. The design can spray the upper end of the spraying assembly when the lower end is detected by the chromatic aberration detector 9, which can reduce the waiting time of the equipment and improve the spraying efficiency.

[0029] The two ends of the top of the paint spraying box 11 are provided with a hanging assembly 14, and the free end of the traction cable 5 is connected with the hanging assembly 14. Specifically, the hanging assembly 14 stably suspends the paint spraying box 11 above the movable sleeve ring 6 through the traction cable 5, so that the paint spraying box 11 always keeps balance, reducing the unstable factors caused by shaking during operation. It is helpful to ensure the accurate position of the spraying nozzle 12, so as to realize the consistency and uniformity of spraying.

[0030] Any one group of the limiting rods 7 includes two independently arranged limiting rods 7 arranged above and below, and the two independently arranged limiting rods 7 are controlled by the same driving motor 8. The end of the limiting rod 7 towards the inner side of the movable sleeve ring 6 is provided with a tightening block 15. Specifically, the two independently arranged limiting rods 7 can improve the stability and avoid the problems of dislocation or insufficient support caused by the change of the tower body 1. The end of the limiting rod 7 and the tightening block 15 are connected through an elastic assembly, which provides higher contact force and adaptability.

[0031] The tightening block 15 is in arc structure, and the outer end surface of the tightening block 15 is provided with an anti-skid surface. Specifically, the arc structure of the tightening block 15 can better fit the surface of the tower, further increasing the gripping effect of the limiting rod 7, preventing the movable sleeve ring 6 from sliding or deviating on the tower body 1. The tightening block 15 effectively offsets the horizontal sliding force that may be generated during the spraying process through its friction force, so as to ensure that the device can be stably fixed in different operating positions.

[0032] The outer wall of the limiting rod 7 is provided with a clamping tooth structure in the axial direction, and the driving motor 8 is engaged with the clamping tooth structure through a rotating gear. Specifically, the clamping tooth structure is arranged in the axial direction and cooperates with the rotating gear of the driving motor 8, so as to realize the accurate extension and position locking of the limiting rod 7. The gear engagement structure can push the limiting rod 7 to extend or retract to a specified position under the instruction of the control system, so as to ensure the adjustment accuracy of the limiting rod 7 and avoid accidental sliding or position deviation of the limiting rod 7 during work.

[0033] The color difference detector 9 is provided with a plurality of color difference detectors 9 arranged at equal intervals. Specifically, the plurality of color difference detectors 9 are arranged at equal intervals on the inner wall of the movable collar 6, which can monitor the color change of the tower surface in real time during the paint spraying process. The spraying can be automatically compensated during the spraying process to ensure the uniformity and coverage of the paint layer.

[0034] The inner diameter of the movable collar 6 is greater than the outer diameter of the bottom of the tower body 1. Specifically, since the shape of the tower body 1 is usually gradually narrowed from the bottom to the top, the inner diameter of the movable collar 6 is designed to be greater than the outer diameter of the bottom of the tower body 1, which helps the movable collar 6 to move between different positions of the tower, and ensures that the paint spraying device can smoothly perform the spraying operation at any height of the tower body 1.

[0035] In example two, on the basis of example one, the specific working principle of the wind power tower automatic paint spraying device is proposed.

[0036] The specific implementation principle process is as follows:

[0037] First, add paint to the paint spraying box 11 through the feeding port 13, and then sleeve the movable collar 6 on the tower body 1. Through the sliding cooperation of the traction cable 5 and the guide wheel 4, the traction device 3 is started, and the traction device moves the movable collar 6 to the top of the tower to prepare for the subsequent spraying work. During the slow descent of the movable collar 6, the color difference detector 9 continuously monitors the color change of the tower surface during the spraying process. Once the color difference anomaly is detected, the control system will control the paint spraying box 11 to move to the vertical direction of the corresponding position, and adjust the spraying amount of the spraying nozzle 12 at the same time. When the spraying nozzle 12 moves down to the detection position, the spraying nozzle 12 starts to spray paint.

However, these corresponding changes and modifications should all belong to the protection scope of the claims attached to the present application.
