Description

Technical Field

[0001] The utility model relates to the technical field of ball valve cutting, in particular to a ball valve cutting protection device. Background Art

[0002] The ball valve is a valve in which the valve stem drives the opening and closing parts to rotate around the axis of the ball valve. It is widely used in various facilities. In the production process, in order to make the surface of the ball valve smoother, a cutting device is needed to cut the surface of the ball valve.

[0003] Before cutting the ball valve, it is often necessary to use a limit mechanism to fix it. Currently, most of the limiters on the market use threaded rods and clamps to limit the position. This limit method often requires manual assistance from staff, making the entire limit process and subsequent material removal process more cumbersome. At the same time, a large amount of debris will be generated during the cutting process. These debris will accumulate on the workbench, thereby affecting the subsequent cutting operations. Therefore, in response to these problems, we need to consider designing a ball valve cutting protection device. Utility Model Content

In view of the usage problem, a limit mechanism is set, and the ball valve body can be limited by an upper limit plate, a lower limit plate, a first limit column, and a second limit column, so as to effectively prevent the ball valve body from escaping from the limit and flying out when rotating. A cleaning mechanism is also set to avoid the accumulation of debris and affect the subsequent cutting operation.

[0023] Among them, it also includes a limiting mechanism, which includes a motor 5 installed at the lower end of the workbench 1, the upper end of the workbench 1 is rotatably connected to a first rotating shaft 6, the lower end of the first rotating shaft 6 passes through the workbench 1 and is fixedly connected to the output shaft of the motor 5, the upper end of the first rotating shaft 6 is fixedly connected to a lower limiting plate 7, the upper end of the lower limiting plate 7 is fixedly connected to a first limiting column 8, the first limiting column 8 can pre-position the ball valve body 20, the upper end of the first limiting column 8 is provided with a rectangular inner groove 9, the upper end of the C-shaped support plate 3 is installed with a telescopic rod 10, the telescopic rod 10 is a hydraulic telescopic rod, and the telescopic end of the telescopic rod 10 is fixedly connected to a mounting plate 11, and the mounting plate 11 is installed. The lower end of the plate 11 is rotatably connected to a second rotating shaft 12, and the lower end of the second rotating shaft 12 is fixedly connected to an upper limit plate 13. The lower limit plate 7 and the upper limit plate 13 cooperate to clamp and limit the ball valve body 20. The lower end of the upper limit plate 13 is fixedly connected to a second limit column 14, and the lower end of the second limit column 14 is fixedly connected to a rectangular strip 15. The rectangular inner groove 9 and the rectangular strip 15 cooperate, and the rectangular strip 15 passes through the rectangular inner groove 9, so that the lower limit plate 7 drives the upper limit plate 13 to rotate synchronously. The upper end of the lower limit plate 7 and the lower end of the upper limit plate 13 are both provided with annular rubber pads, which can improve the stability of the limit clamping;

[0024] It also includes a cleaning mechanism, which is used to clean the debris generated by cutting. The cleaning mechanism includes a vacuum cleaner 16 installed on the upper end of the workbench 1 (this is the prior art, and the vacuum cleaner 16 is mainly composed of a motor, a filtering system, a dust bag and other components). A cleaning block 17 is fixedly connected to the upper end of the workbench 1. A cleaning cavity is provided in the cleaning block 17.

[0025] In the utility model, before use, first ensure that the rectangular strip 15 is aligned with the rectangular inner groove 9. When in use, first align the circular through groove on the ball valve body 20 with the first limit column 8 and insert it. Figure 1 As shown, the ball valve body 20 is placed on the lower limit plate 7, so that the pre-positioning of the ball valve body 20 can be completed, and then the telescopic rod 10 is controlled to drive the mounting plate 11, the upper limit plate 13, the second limit column 14 and the rectangular strip 15 to move downward synchronously until the lower end of the upper limit plate 13 is against the upper end of the ball valve body 20. During the downward movement, the second limit column 14 will penetrate the circular through groove on the ball valve body 20, and the rectangular strip 15 will penetrate the rectangular inner groove 9, so that the stable limit of the ball valve body 20 can be completed. When unloading is required later, it is only necessary to control the telescopic rod 10 to drive the upper limit plate 13 to move upward to release the limit. The entire limit process is convenient and fast, and effectively prevents the ball valve body 20 from escaping from the limit and flying out during high-speed rotation and cutting;

[0026] After the limiting is completed, the motor 5 can be started to drive the first rotating shaft 6 to rotate, and drive the lower limit plate 6 and the first limit column 8 to rotate synchronously. Since the rectangular strip 15 passes through the rectangular inner groove 9, the upper limit plate 13 can rotate synchronously, thereby driving the ball valve body 20 to rotate. At this time, the staff can control the cutting device 4 to start the cutting operation. During the cutting process, the staff can start the vacuum cleaner 16 to absorb and clean the debris generated during cutting into the vacuum cleaner 16 through the cleaning port 18 and the connecting pipe 19, thereby avoiding the accumulation of cutting debris on the workbench 1 and affecting the subsequent cutting operation, thereby ensuring the normal cutting operation.
