Description

Technical Field

[0001] This utility model relates to the field of shot blasting auxiliary equipment technology, specifically to a shot blasting sealing device. Background Technology

[0002] Shot blasting is a surface treatment technology that uses shot blasters to propel steel shot at high speed onto the surface of a material. Compared to other surface treatment technologies, it is faster, more efficient, and can be used for partial retention or casting processes after stamping.

[0003] When using shot blasting machines to clean and grind steel structures such as box columns, the impact direction of the high-speed shot is random and irregular. Since the two ends of the box column are generally open, the high-speed shot will enter the hollow cavity of the box column during impact grinding. As the shot blasting time increases, a lot of steel shot will be retained inside the box component, which will make it impossible to recover the steel shot and steel shot, making cleaning difficult. Moreover, the steel shot that has entered the inner cavity of the box column is difficult to handle, resulting in incomplete cleaning and increasing the workload of the workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shot blasting sealing device that can be detachably installed at the port of a box-shaped column. This device seals the inner cavity of the box-shaped column during shot blasting, facilitating the recovery of steel shot and reducing the labor intensity of workers.

[0005] This utility model is achieved through the following technical solution: A shot blasting sealing device is provided, including a sealing plate, a central rod, and a movable stop. The central rod passes through the sealing plate and is slidably connected to it. A U-shaped lever is hinged to the upper end of the central rod via a horizontal shaft. Both ends of the U-shaped lever are connected to circular rotating disks. The two rotating disks are facing each other and are parallel. Through holes for the two ends of the horizontal shaft to rotate through are respectively opened at the same position on the eccentric part of the two rotating disks. An adjusting nut is threaded to the lower end of the central rod. The movable stop is located below the sealing plate. A fixed through groove for the central rod to pass through is opened in the middle of the movable stop along its length. The width of the fixed through groove is smaller than the diameter of the adjusting nut.

[0006] Furthermore, one end of the movable stop has a recessed groove on the side facing the sealing plate, and a fixed magnetic block is engaged in the groove.

[0007] Preferably, the surface of the magnetic block is flush with the plane of the movable stop.

[0008] By setting the surface of the magnetic block to be flush with the plane of the movable stop, the magnetic block is embedded in the surface of the movable stop, ensuring the contact area between the movable stop and the box-shaped column port and improving stability.

[0009] Furthermore, the center rod includes a smooth rod and a threaded rod fixed to one end of the smooth rod and cooperating with an adjusting nut. A positioning groove is recessed along the circumferential length of the threaded rod, and a positioning ruler with scale values ​​is provided in the positioning groove.

[0010] The smooth rod of the center rod is slidably connected to the sealing plate. The threaded rod limits the movable stop by adjusting the nut. The position of the movable stop can be adjusted according to the thickness of the bottom plate of the box column of different models by setting the positioning ruler in the positioning groove. This ensures that the sealing plate and the movable stop can be clamped on the end panel of the box column when the sealing device is installed, thus ensuring the stability of the installation.

[0011] The beneficial effects of this utility model are: The shot blasting sealing device of this invention is reusable and easy to operate; by using the sealing device, steel shot is isolated outside the component, with less residue, improving cleaning efficiency and effectively enhancing safety.

[0012] This utility model's shot blasting sealing device is easy to disassemble and install. Furthermore, the position of the movable stop can be adjusted according to the thickness of the end panel of different box-type columns, thereby ensuring the stability of the sealing device during installation and improving the sealing effect. During shot blasting, the device quickly seals the pre-reserved holes on the upper and lower end partitions of the box-type column. The device is reusable and cost-effective.

[0018] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0019] A shot blasting sealing device includes a sealing plate 4, a central rod 6, and a movable stop 8. The central rod 6 vertically penetrates the sealing plate 4 and is slidably connected to the sealing plate 4. The shape of the sealing plate 4 can be selected according to the actual situation. In this embodiment, the sealing plate 4 is set as a circle. The end of the central rod 6 located above the sealing plate 4 is hinged to a U-shaped lever 7 via a horizontal shaft 5. Both ends of the U-shape of the lever 7 are connected to a circular rotating disk 12. The two rotating disks 12 are facing each other and are arranged in parallel. Through holes are opened at the same position on the eccentric part (i.e., the non-center part) of the two rotating disks 12, allowing the two ends of the horizontal shaft 5 to rotate through. The end of the central rod 6 located below the sealing plate 4 is threadedly connected to an adjusting nut 9. The movable stop 8 is located below the sealing plate 4. A fixed through groove 10 is opened in the middle of the movable stop 8 along its length direction for the central rod 6 to pass through. The width of the fixed through groove 10 is smaller than the diameter of the adjusting nut 9 to prevent the adjusting nut 9 from entering the fixed through groove 10, so as to facilitate the adjustment of the position of the movable stop 8.

[0020] One end of the movable stop 8 has a recessed groove on the side facing the sealing plate 4, and a magnetic block 11 is fixed in the groove. The surface of the magnetic block 11 is flush with the plane of the movable stop 8.

[0021] The center rod 6 includes a smooth rod 61 and a threaded rod 62 fixed to one end of the smooth rod 61 and cooperating with the adjusting nut 9. A positioning groove 13 is recessed in the circumferential length direction of the threaded rod 62, and a positioning ruler 14 with scale value is provided in the positioning groove 13.

[0022] The working process of this utility model: When shot blasting the box-shaped column 1, the reserved holes 3 on the end plates 2 at both ends are sealed. The movable stop 8 can be tilted by the movable range of the fixed through groove 10 so that it can be placed into the hole 3 of the end plate 2. The magnetic block 11 set at one end can be easily attracted to the inside of the end plate 2, while the other end can be rotated with the other end as the center to adjust its position, so that the other end also fits against the inside of the end plate 2. At this time, the sealing plate 4 is located outside the hole 3. By moving the lever 7, the rotating disk 12 at the end of the lever 7 can be rotated eccentrically, so that the rotating disk 12 can apply force to the sealing plate 4, thereby clamping and positioning the sealing plate 4 and the movable stop 8 on the inner and outer sides of the end plate 2 at the same time, so that the sealing plate 4 completes the sealing of the hole 3 of the end plate 2. In this way, during shot blasting, steel shot can be prevented from entering the inner cavity of the box-shaped column 1 through the hole 3, which facilitates the recovery and cleaning of steel shot and reduces the labor intensity of the workers.

[0023] Because the steel components are of different models and the end plates 2 of different box-type columns 1 are of different thicknesses, when using this utility model for sealing, the position of the adjusting nut 9 on the threaded rod 62 and the position of the movable stop 8 on the center rod 6 can be adjusted in advance according to the different thicknesses of the end plates 2. This adjusts the distance between the movable stop 8 and the sealing plate 4, so that when the operating lever 7 is rotated, the sealing plate 4 and the movable stop 8 can be clamped and fixed to the end plate 2 at the same time, thus ensuring the sealing effect. The position of the movable stop 8 can be accurately adjusted using the positioning ruler 14 with scale values ​​in the positioning groove 13 on the threaded rod 62, so as to achieve advance adjustment and facilitate the quick installation of the sealing device before shot blasting. This ensures that after the lever 7 is pressed down, the sealing plate 4 and the movable stop 8 can be accurately clamped and locked on the inner and outer sides of the end plate 2, improving the installation efficiency.
