Description

Technical Field

[0001] The utility model relates to the technical field of spherical tank detection, in particular to a supporting platform for spherical tank detection. Background Art

[0002] Spherical tanks are large-capacity, pressure-bearing, spherical steel storage containers widely used in the petroleum, chemical, and metallurgical industries. They can store liquefied petroleum gas (LPG), liquefied natural gas (LNG), liquid oxygen, liquid ammonia, liquid nitrogen, and other media. Spherical tanks are subject to stringent manufacturing, welding, and assembly requirements, and the tanks must be inspected before loading.

[0003] At present, in traditional detection devices, the spherical tank is often fixed by a bracket, and then the detection instrument is rotated around the outer wall of the spherical tank to detect the tank body and check whether the spherical tank is damaged. However, this method requires moving the detection instrument around the outside of the spherical tank, which is more troublesome during detection. At the same time, since the bracket supports the spherical tank, it will block the outer wall of the spherical tank, making it impossible for the detection instrument to perform all-round detection of the outer wall of the spherical tank.

[0031] Reference Figure 1-3 A support platform for spherical tank inspection is used to support and fix the spherical tank during inspection, in order to facilitate the support of the spherical tank without affecting the inspection of the outer wall of the spherical tank.

[0032] The support platform for spherical tank inspection includes a base 1, a moving rod 7, a movable cylinder 8, multiple groups of support mechanisms and a driving mechanism;

[0033] The base 1 is used to place the tank body 2. The top of the tank body 2 is provided with an opening. The base 1 is provided with a first push rod 3. The upper end of the first push rod 3 is fixedly connected to the first movable plate 4. The upper end of the movable cylinder 8 is rotatably connected to the first movable plate 4. The first push rod 3 is an electric push rod, which can push the first movable plate 4 to move up and down. A second push rod 5 is provided on the first movable plate 4. The upper end of the second push rod 5 is fixedly connected to the second movable plate 6. The upper end of the movable rod 7 is connected to the second movable plate 6. The second push rod 5 is an electric push rod, which can push the second movable plate 6 to move up and down.

[0034] Each supporting mechanism is arranged at intervals around the moving rod 7. Each supporting mechanism includes a supporting rod 15 and a connecting rod 13. The lower end of the supporting rod 15 is rotatably connected to the lower end of the moving rod 7, and the other end is rotatably connected to the lower end of the connecting rod 13. The upper end of the connecting rod 13 is rotatably connected to the lower end of the movable cylinder 8. The movable cylinder 8 is sleeved on the outside of the moving rod 7. The lower ends of the moving rod 7 and the movable cylinder 8 can pass through the opening and extend into the interior of the tank body 2, so that each supporting mechanism passes through the opening together and enters the interior of the tank body 2. At this time, the second movable plate 6 is driven to move by the second push rod 5, so that the moving rod 7 can be moved upward, thereby driving each supporting rod 15 to open to support the inner wall of the tank body 2.

[0035] The driving mechanism includes a motor 11, which is fixedly connected to the first movable plate 4. A transmission gear 12 is provided on the output shaft of the motor 11. An end gear 10 is provided on the outside of the movable cylinder 8. The end gear 10 is engaged with the transmission gear 12. The motor 11 drives the end gear 10 to rotate through the transmission gear 12, thereby driving the movable cylinder 8 to rotate, so that each supporting mechanism rotates accordingly, thereby driving the tank body 2 to rotate, making it convenient to detect the outer wall of the tank body 2. During the detection, the outer wall of the tank body 2 is detected by a detection device, and the detection equipment can be an ultrasonic detector or other detection equipment.

[0036] In order to facilitate the rotation of the tank body 2, a circular through hole is opened on the first movable plate 4, and the upper end of the movable cylinder 8 passes through the circular through hole. The upper end of the movable cylinder 8 is provided with multiple support wheels 9 around the axis. When the movable cylinder 8 rotates, the movable cylinder 8 can be rotatably supported by the support wheels 9, thereby improving the stability of the rotation of the movable cylinder 8.

[0037] The upper end of the moving rod 7 is fixedly connected to the second moving plate 6, and the lower end is rotatably connected to the rotating plate 16. The lower end of the support rod 15 is rotatably connected to the rotating plate 16. When the movable cylinder 8 drives the support rods 15 in each supporting mechanism to rotate, the bottom end of the support rod 15 rotates at the bottom of the moving rod 7 through the rotating plate 16, thereby avoiding the rotation of the support rod 15 affecting the moving rod 7.

[0038] In addition, a rubber ball 14 is fixedly connected to the upper end of the support rod 15. When the support rod 15 supports the inner wall of the tank body 2, the rubber ball 14 will contact the inner wall of the tank body 2, thereby preventing the support rod 15 from directly contacting the inner wall of the tank body 2 and causing damage to the inner wall of the tank body 2.

[0039] The working principle of the support platform for spherical tank inspection is as follows: first, the tank body 2 is transported to the base 1 by a crane or other transportation equipment, and then the first push rod 3 drives the first movable plate 4 to descend, so that the lower ends of the movable rod 7 and the movable cylinder 8 pass through the opening and extend into the interior of the tank body 2, thereby allowing each supporting mechanism to enter the interior of the tank body 2. At this time, the second push rod 5 drives the second movable plate 6 to move upward, thereby moving the movable rod 7 upward. Under the action of the connecting rod 13, each support rod 15 opens to the surroundings, and then the first push rod 3 drives the first movable plate 4 to rise, thereby driving the movable rod 7 and the movable cylinder 8 to rise as a whole. The rubber ball 14 on each support rod 15 presses against the inner wall of the tank body 2 and lifts the tank body 2 upward to make it leave the base 1.

[0040] During the inspection, the motor 11 can drive the transmission gear 12 to rotate, thereby driving the end gear 10 to rotate, and the end gear 10 drives the movable cylinder 8 to rotate, so that each supporting mechanism rotates accordingly. Since each support rod 15 supports the tank body 2 at this time, it drives the tank body 2 to rotate accordingly, making it convenient to perform all-round inspection of the outer wall of the tank body 2.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
