[0003] In the prior art, the sliding component of the manual shot blasting platform is usually installed inside the shot blasting chamber. The sliding component can move left and right. The operator stands on the platform and moves to the workpiece to be repaired through the sliding component. However, this installation method makes it easy for dust to adhere to the sliding component, resulting in an increased scrap rate of the sliding component inside the shot blasting chamber. Based on this, this application proposes an automatic extension worktable. Utility Model Content

[0006] The drive assembly is located outside the shot blasting chamber. The drive assembly includes a support frame connected to the outside of the shot blasting chamber. The bottom of the support frame is connected to the shot blasting chamber via a reinforcing rod. The inner cavity of the support frame is provided with a drive structure and a limiting pulley group. The moving steel pipe is driven by the drive structure. The limiting pulley group includes two limiting pulleys vertically distributed vertically. The moving steel pipe is located between the two limiting pulleys, and the limiting pulleys are in contact with the moving steel pipe. The limiting pulleys are movably connected to the support frame.

[0007] Preferably, the driving structure includes a driving roller that contacts the moving steel pipe and a geared motor connected to the support frame. The driving roller is movably connected to the support frame and is driven by the geared motor.

[0008] Preferably, the reinforcing rod is inclinedly disposed at the bottom of the support frame, the lower end of the reinforcing rod is connected to the shot blasting chamber, and the upper end of the reinforcing rod is connected to the bottom of the support frame at the end away from the shot blasting chamber.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. By placing the drive assembly outside the shot blasting chamber, the automatic extension worktable can avoid the corrosion of the drive structure by the internal environment of the shot blasting chamber, extend the service life of the drive structure, and thus extend the service life of the automatic extension worktable; by setting the reinforcing rod, the strength of the support frame can be increased, and the reliability of the worktable can be improved.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides an embodiment: Please refer to Figures 1-4An automatic extension worktable includes a moving component and a driving component. The moving component includes a moving steel pipe 2 and a moving platform 5. The moving steel pipe 2 is movably mounted on the wall of the shot blasting chamber. One end of the moving steel pipe 2 is located inside the shot blasting chamber, and the moving platform 5 is provided at one end of the moving steel pipe 2. The other end of the moving steel pipe 2 is located outside the shot blasting chamber. The driving component is located outside the shot blasting chamber. By placing the driving component outside the shot blasting chamber, the corrosion of the driving component by the internal environment of the shot blasting chamber can be avoided, the service life of the driving component can be extended, and thus the service life of the automatic extension worktable can be improved.

[0019] The drive assembly includes a support frame 1 connected to the outside of the shot blasting chamber. The bottom of the support frame 1 is connected to the shot blasting chamber via a reinforcing rod 6. The reinforcing rod 6 is inclinedly set at the bottom of the support frame 1. The lower end of the reinforcing rod 6 is connected to the shot blasting chamber, and the upper end of the reinforcing rod 6 is connected to the bottom of the support frame 1 at the end away from the shot blasting chamber. By setting the reinforcing rod 6, the strength of the support frame 1 can be enhanced, and the reliability of the worktable can be improved.

[0020] The inner cavity of the support frame 1 is equipped with a drive structure. The moving steel pipe 2 is driven by the drive structure. The drive structure includes a drive roller that contacts the moving steel pipe 2 and a reduction motor connected to the support frame 1. The drive roller is movably connected to the support frame 1. The drive roller is driven by the reduction motor. When the reduction motor drives the drive roller to rotate, the drive roller transmits power through the contact friction between itself and the surface of the moving steel pipe 2. The rotational motion is converted into the linear motion of the moving steel pipe 2 by the friction, thereby realizing the movement of the moving platform 5 in the shot blasting chamber, which makes it convenient for workers to stand on the moving platform 5 to perform touch-up painting operations.

[0021] like Figure 3 As shown, in some embodiments of this application, the driving structure includes an upper driving roller 4 that contacts the top of the moving steel pipe 2, a lower driving roller 7 that contacts the bottom of the moving steel pipe 2, a first geared motor 9 that drives the upper driving roller 4, and a second geared motor 8 that drives the lower driving roller 7. The first geared motor 9 and the second geared motor 8 rotate in opposite directions. The combined use of the first geared motor 9 and the second geared motor 8 can realize the translation of the moving steel pipe 2.

[0022] The inner cavity of the support frame 1 is movably connected to a limiting pulley assembly, which includes two vertically distributed limiting pulleys 3. The movable steel pipe 2 is located between the two limiting pulleys 3, and the limiting pulleys 3 are in contact with the movable steel pipe 2. The limiting pulleys 3 are movably connected to the support frame 1. By setting the limiting pulleys 3, the limiting pulleys 3 can limit the movement of the movable steel pipe 2, reduce the vibration and swaying of the movable steel pipe 2 during movement, and improve the stability of the moving platform 5.

[0023] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0024] In summary: When using this automatic extension worktable, if... Figure 4 As shown, the movable steel pipe 2 passes through the wall of the shot blasting chamber, and one end of it is connected to the movable platform 5, which is located inside the shot blasting chamber. The other end of the movable steel pipe 2 is located outside the shot blasting chamber and passes through the inner cavity of the support frame 1. The other end of the movable steel pipe 2 is limited by the limiting pulley 3.

[0025] When a touch-up painting operation is required, the worker stands on the mobile platform 5. The geared motor drives the drive roller connected to it to rotate. The drive roller uses the friction between itself and the mobile steel pipe 2 to move the mobile steel pipe 2 horizontally. The mobile steel pipe 2 drives the mobile platform 5 to move, and the position of the worker in the shot blasting chamber can be changed, making it easier for the worker to carry out the touch-up painting operation.
