Description

Technical Field

[0001] This utility model relates to the field of wind turbine blades, and in particular to an automatic painting device for wind turbine blades. Background Technology

[0002] An existing patent (publication number: CN215612713U) discloses an automatic painting device for wind turbine blades. It includes a mobile vehicle with wheels fixedly installed at the four corners of its bottom. A mounting base is fixedly installed on top of the mobile vehicle. A sliding frame is fixedly installed at the center of the mounting base. Two sliding frames are used, arranged parallel to each other, and a sliding plate is slidably connected between the two frames. A lifting cylinder is located below the sliding plate. The lifting cylinder is fixedly installed on the mounting base. However, this device, with wheels fixedly installed at the four corners of its bottom, relies on a painting assembly on the upper part of the mobile vehicle for roller painting. During the horizontal roller painting process on the wind turbine blades, if the operator needs to move the mobile vehicle laterally multiple times according to the painting position, the wheels on the lower part of the mobile vehicle will experience distance deviations during movement. This requires repeated calibration of the painting position, increasing the workload of personnel and affecting the working efficiency of the equipment. Summary of the Invention

[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing a wind turbine blade painting operation using a spray gun at the front of an angle frame. The equipment base is configured with multiple sets. After assembling and connecting the docking slots and docking plates according to the blade length, the drive motor inside the worktable drives the drive gear to rotate. Simultaneously, the drive gear rotates the transmission gear and causes the gear on the side of the main gear shaft to mesh and move on the upper part of the rack. Therefore, during the automatic painting process, since the equipment base is in a fixed position, there is no need for multiple calibrations of the painting position on the equipment, thus increasing the working efficiency of the wind turbine blade automatic painting device.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] An automatic painting device for wind turbine blades includes a base, support rollers, a drive shaft, a main gear shaft, a clamping platform, a clamping plate, a center frame, an internally threaded cylinder, and a positioning rod. The base has a docking groove at the rear and a docking plate at the front. The docking groove is adapted to the docking plate, and the docking groove connects to the docking plate. The docking plate is inserted into the docking groove, and the docking groove is fixedly connected to the docking plate by bolts. The rear of the worktable has a support roller shaft groove, which is adapted to the support roller and connects to it. The support roller rotates within the support roller shaft groove. The wheel rotates on the upper part of the equipment base. The worktable has a drive groove inside. The motor shaft is rotatably connected to the side of the drive groove. The side of the drive groove is fixedly connected to the drive motor. The output shaft of the drive motor is fixedly connected to the motor shaft. The front of the worktable has a drive shaft groove. The drive shaft groove is adapted to the drive shaft. The drive shaft groove is connected to the drive shaft. The drive shaft rotates inside the drive shaft groove. Both the drive shaft and the motor shaft have drive gears inside. The two sets of drive gears mesh with each other. The lower part of the worktable has a main gear shaft groove. The main gear shaft is rotatably connected inside the main gear shaft groove.

[0006] The front part of the main gear shaft and the side part of the drive shaft are both fixedly connected to the transmission gears, and the two sets of transmission gears mesh with each other. The side part of the worktable has a slot for the auxiliary gear shaft, and the auxiliary gear shaft is rotatably connected inside the slot. The front part of the main gear shaft and the front part of the auxiliary gear shaft are both fixedly connected to the gears. The side part of the equipment base has a rack, and the gears mesh on the upper part of the rack. The side part of the worktable is fixedly connected to the guide wheel frame screw. The upper part of the guide wheel frame has a clamping platform. The guide wheel frame screw is adapted to the clamping platform. The guide wheel frame screw is connected to the clamping platform, and the clamping platform slides on the side part of the guide wheel frame screw. Beneficial effects

[0007] 1. In the operation of this automatic wind turbine blade painting equipment, the wind turbine blades are painted using a spray gun at the front of the angle frame. The equipment base is set in multiple sets. After the equipment base is assembled and connected with the docking slot and docking plate according to the blade length, the drive motor inside the worktable drives the drive gear to rotate. The drive gear drives the transmission gear to rotate, and at the same time, it drives the gear on the side of the main gear shaft to mesh and move on the rack. Thus, during the automatic painting process, since the equipment base is in a fixed position, there is no need to repeatedly calibrate the painting position on the equipment, thereby increasing the working efficiency of the equipment.

[0008] 2. During the use of this utility model of automatic painting equipment for wind turbine blades, the worktable is moved by gears on the side of the worktable, and the worktable is supported by rollers at the bottom of the worktable. The worktable is also guided by two sets of guide wheels on the side of the worktable, so as to avoid gear tilting and jamming during the movement of the equipment, thereby increasing the stability of the equipment.

[0009] 3. During the use of this utility model of automatic painting equipment for wind turbine blades, the lifting screw is driven to rotate by the screw motor, which in turn drives the center frame to rise and fall. At the same time, the guide seat on the side of the center frame slides and guides the center frame on the side of the guide rail, so as to avoid the center frame from shifting due to the rotation of the lifting screw, which would affect the painting effect, thereby further increasing the stability of the equipment.
