Description

Technical Field

[0001] The utility model relates to a high-altitude five-axis working platform for surface treatment of large workpieces. Background Art

[0002] In the traditional coating industry, when performing surface treatment operations on large-sized workpieces, especially large spherical and curved workpieces, auxiliary tools such as aerial platforms and ladders are required. The disadvantages of this production method are:

[0003] 1. The operating range of personnel usually cannot effectively cover all positions of the workpiece. In the process of constantly moving the aerial platform or ladder, the operators not only increase the ineffective working time, but also increase the additional working space, resulting in generally low efficiency of workpiece surface treatment and low utilization rate of the factory;

[0004] 2. The coating will also become less uniform, have color difference, and have low appearance due to intermittent operation.

[0005] As the coating industry continues to develop in the direction of automation and intelligence, this "climbing vehicle + ladder" production method is increasingly unable to meet the company's operational requirements for surface treatment of large workpieces. Therefore, how to improve the quality and efficiency of surface treatment of large workpieces and increase the utilization rate of factory buildings has become a major issue that needs to be solved urgently. Utility Model Content

[0006] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a high-altitude five-axis work platform with a rational structural design for surface treatment of large workpieces, which greatly improves the efficiency and quality of surface treatment of large workpieces and reduces the labor intensity of operators.

[0007] The technical solution adopted by the utility model to solve the above-mentioned problem is: a high-altitude five-axis working platform for surface treatment of large workpieces, characterized in that: it includes a frame, an X-axis operating mechanism, a Y-axis operating mechanism, a Z-axis telescopic arm mechanism, an R-axis rotating mechanism and an L-axis telescopic platform; the X-axis operating mechanism includes an X-axis crane and an X-axis track, the X-axis crane is installed on the X-axis track, and the X-axis track is fixed on the frame; the Y-axis operating mechanism includes a Y-axis crane and a Y-axis track; the Y-axis crane is installed on the Y-axis track, and the Y-axis track is fixed on the X-axis crane; the R-axis rotating mechanism includes a motor seat, a driving motor, a slewing support seat and a slewing support; the motor seat and the slewing support seat are both fixedly installed on the Y-axis crane, the driving motor is fixedly installed on the motor seat, the slewing support is horizontally rotatably installed on the slewing support seat, and the driving motor is connected to the slewing support; the Z-axis telescopic arm mechanism is fixedly installed on the slewing support; the L-axis telescopic platform includes a telescopic fork and a hanging basket, the telescopic fork is installed on the last telescopic arm of the Z-axis telescopic arm mechanism, and the hanging basket is installed on the last fork of the telescopic fork.

[0008] The driving motor of the utility model is connected with the slewing support through a gear mechanism.

[0009] The utility model is provided with an anti-collision block at the bottom of the hanging basket.

[0010] The utility model provides an operator head protection frame on the top of the hanging basket.

[0011] The utility model provides limiting devices at both ends of the X-axis track.

[0012] The utility model is provided with guide wheels on both the X-axis crane and the Y-axis crane.

[0013] The utility model is provided with cleaning devices at both ends of the X-axis crane and the Y-axis crane.

[0017] 2. Since there is no need for auxiliary tools such as aerial platforms or ladders, the work site can be saved to a certain extent, thereby improving the utilization rate of the factory building and reducing the risk of workers falling, which greatly improves the safety of operators' work.

[0018] 3. The utility model has the characteristics of compact structure, light weight, simple operation, flexible and reliable movement, etc. It can flexibly adjust the position according to the different sizes of workpieces and different working contents, and has a wider range of applications.
