Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tower outer wall spraying technology, specifically relating to a tower outer wall spraying equipment. Background Technology
[0002] Wind turbine towers are exposed to complex outdoor environments for extended periods, enduring strong winds, rain, ultraviolet radiation, and significant temperature fluctuations. This makes them highly susceptible to corrosion and wear, which not only reduces their lifespan but can also threaten the safe and stable operation of the wind power system. Therefore, efficient and high-quality spraying of the outer walls of wind turbine towers to enhance their protective performance has become a necessary step in ensuring the sustainable development of the wind power industry.
[0003] Currently, existing wind turbine tower exterior coating equipment mainly includes a tower frame supporting the wind turbine tower, a base frame mounted on one side of the tower frame, and a coating assembly horizontally slidably mounted on the base frame. The coating assembly ensures comprehensive coating of the wind turbine tower primarily through the sliding of the coating assembly on the base frame and the rotation of the wind turbine tower on the tower frame. For example, Chinese patent application number 2024220488197 provided a wind turbine tower coating device.
[0004] However, most existing tower exterior coating equipment has certain limitations. Specifically, the existing tower exterior coating equipment generally uses a structure where a column is installed above a base, a sliding frame is vertically slidably mounted on the surface of the column, a horizontal telescopic cylinder is installed on the surface of the sliding frame, a rotating rod is installed at the end of the horizontal telescopic cylinder, and spray guns are installed at both ends of the rotating rod. Therefore, when using this equipment for tower exterior coating operations, adjusting the height of the spray gun and the horizontal distance between the spray gun and the tower not only requires separate control of two sets of power sources, but also suffers from low adjustment efficiency in terms of height adjustment. Utility Model Content
[0005] The purpose of this invention is to address the problem of low height adjustment efficiency in existing tower outer wall spraying equipment, and to propose and design a new type of tower outer wall spraying equipment that can improve the efficiency of spray gun height adjustment, thereby increasing the overall spraying speed.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a tower outer wall spraying device, comprising a base frame, with a spraying unit horizontally slidably mounted on the upper end of the base frame; the spraying unit includes a sliding box horizontally slidably mounted on the base frame; a column is mounted on the upper part of the sliding box, a sliding frame is vertically slidably mounted on the surface of the column, an mounting plate is mounted on the surface of the sliding frame, a lifting drive mechanism and a tilting drive mechanism are mounted on the mounting plate, the upper end of the tilting drive mechanism is the output end, and the output end of the tilting drive mechanism can tilt upward linearly and tilt downward linearly; a spraying mechanism is mounted on the output end of the tilting drive mechanism. In this way, it can both drive the sliding frame and the spraying mechanism to vertically lift and lower through the lifting drive mechanism, and simultaneously drive the spraying mechanism to vertically lift and lower and horizontally extend and retract through the tilting drive mechanism, thereby improving the vertical movement efficiency of the spraying mechanism and thus increasing the overall spraying speed.
[0007] Furthermore, the spraying mechanism includes a mounting frame, one end of which is fixedly connected to the output end of the tilting drive mechanism, and a rotating arm is rotatably mounted on the other end of the mounting frame. A rotating rod is rotatably mounted on the end of the rotating arm away from the mounting frame. The rotation plane of the rotating rod is perpendicular to the rotation plane of the rotating arm. A spray gun is mounted on the end of the rotating rod, and the spray angle of the spray gun can be flexibly adjusted by the rotation of the rotating arm and the rotation of the rotating rod.
[0008] Furthermore, the spraying unit also includes an electrical cabinet, which is mounted on the upper side of the slide box and moves horizontally together with the slide box.
[0009] Furthermore, the spraying unit also includes a protective cover, which is placed on the outside of the mounting plate and protects the lifting drive mechanism and the tilting drive mechanism.
[0010] Furthermore, a bellows cover is installed between the mounting plate and the mounting bracket, and the bellows cover protects the portion of the tilting drive mechanism located outside the protective cover.
[0011] Furthermore, a cable chain bracket is installed on the surface of the sliding frame, and the cable chain connected to the spraying mechanism is supported by the cable chain bracket.
[0012] Furthermore, a telescopic cover is installed between the upper end of the sliding frame and the upper end of the column, and a telescopic cover is installed between the lower end of the sliding frame and the lower end of the column. The telescopic covers are used to cover the vertical guide rails, vertical racks and other components on the surface of the column that cooperate with the sliding frame, so as to prevent the paint sprayed on them from causing contamination.
[0013] Furthermore, the tilting drive mechanism is an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, and the spraying mechanism can be directly tilted upward or downward through the action of the tilting drive mechanism.
[0014] As can be seen from the above technical solutions, this utility model has the following advantages: This utility model can drive the sliding frame and the spraying mechanism to move vertically up and down through the lifting drive mechanism, and can also drive the spraying mechanism to move vertically up and down and horizontally extend and retract through the tilting drive mechanism, thereby greatly improving the vertical movement efficiency of the spraying mechanism and thus improving the overall spraying speed; at the same time, it also solves the problem that when the gun is blocked during high-level construction, a permanent platform needs to be built on site or a lifting platform needs to be temporarily borrowed to deal with the accident.

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0020] like Figure 1 , Figure 2As shown, this utility model provides a tower outer wall spraying device, which includes a base frame 1 and a spraying unit horizontally slidably mounted on the upper end of the base frame 1. The spraying unit includes a sliding box 2 horizontally slidably mounted on the base frame 1, and the horizontal sliding connection structure between the sliding box 2 and the base frame 1 preferably adopts the horizontal sliding connection structure between the sliding box 2 and the base frame 1 as described in Chinese Patent Application No. 2024220488197. An electrical cabinet 11 and a column 10 are mounted on the upper part of the sliding box 2. A vertical guide rail is provided on the surface of the column 10, and a sliding frame 4 is vertically slidably mounted on the vertical guide rail. A telescopic cover 7 is installed between the upper end of the sliding frame 4 and the upper end of the column 10, and a telescopic cover 3 is installed between the lower end of the sliding frame 4 and the lower end of the column 10. The telescopic covers 7 and 3 cover the vertical guide rail and other components on the surface of the column 10 that cooperate with the sliding frame 4, preventing contamination from the sprayed paint.
[0021] The sliding frame 4 is equipped with a mounting plate 18 and a protective cover 5. Inside the protective cover 5, a lifting drive mechanism 12 is mounted on the mounting plate 18. The lifting drive mechanism 12 drives the sliding frame 4 and the mounting plate 18 to move vertically up and down along the vertical guide rail. Specifically, in this embodiment, the lifting drive mechanism 12 includes a lifting drive motor mounted on the mounting plate 18. The power output end of the lifting drive motor is connected to a drive gear. The drive gear meshes with a vertical rack mounted vertically on the surface of the column 10. The meshing between the drive gear and the vertical rack drives the sliding frame 4 and the mounting plate 18 to move vertically up and down along the vertical guide rail.
[0022] In addition, a tilting drive mechanism 19 and a cable carrier 6 are also mounted on the surface of the mounting plate 18. The tilting drive mechanism 19 adopts a structure capable of outputting linear reciprocating motion, such as an electric cylinder, hydraulic cylinder, or pneumatic cylinder. Simultaneously, the upper end of the tilting drive mechanism 19 is configured as an output end, enabling it to tilt upwards and downwards in a linear motion to drive the spraying mechanism 8 mounted on the output end of the tilting drive mechanism 19 in a linear reciprocating motion. Preferably, to ensure that the spraying mechanism 8 has a large spraying range and spraying angle, the spraying mechanism 8 in this invention preferably adopts the following structure: the spraying mechanism 8 includes a mounting frame 13, one end of which is fixedly connected to the output end of the tilting drive mechanism 19. Furthermore, a bellows cover 9 is installed between the mounting plate 18 and the mounting frame 13, and this bellows cover 9 protects the portion of the tilting drive mechanism 19 located outside the protective cover 5. A rotating arm 15 is rotatably mounted on the other end of the mounting bracket 13, and the rotating arm 15 is driven by a rotating motor 14. A rotating rod 16 is rotatably mounted on the end of the rotating arm 15 away from the mounting bracket 13, and the rotating rod 16 is driven by a rotating motor 2. At the same time, the rotation plane of the rotating rod 16 is perpendicular to the rotation plane of the rotating arm 15, and the rotation plane of the rotating arm 15 is perpendicular to the movement direction of the power output end of the tilting drive mechanism 19. A spray gun 17 is mounted on the end of the rotating rod 16, and the spray angle of the spray gun 17 can be flexibly adjusted by the rotation of the rotating arm 15 and the rotation of the rotating rod 16.
[0023] Based on this, when using this utility model for tower outer wall spraying operations, it can drive the sliding frame 4 and spraying mechanism 8 to move vertically up and down through the lifting drive mechanism 12, and can also drive the spraying mechanism 8 to move vertically up and down and horizontally extend and retract through the tilting drive mechanism 19, thereby improving the vertical movement efficiency of the spraying mechanism 8 and thus improving the overall spraying speed; at the same time, it also solves the problem that when the gun is blocked during high-level construction, a permanent platform needs to be built on site or a temporary lifting platform needs to be borrowed to deal with the accident.
