Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessel inspection, and in particular relates to a flaw detection tool for pressure vessels. Background Art

[0002] Pressure vessels are closed containers that can withstand pressure. They are widely used and play an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. Among them, the most widely used are in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. Pressure vessels are widely used in the chemical and petrochemical fields.

[0003] The prior art discloses a pressure vessel flaw detection inspection tool with patent announcement number CN220289450U. The above patent utilizes the metal material of the pressure vessel to adsorb the equipment plate to the surface of the pressure vessel through a magnet. The equipment plate can be moved by a moving wheel under the push of the operator, and the user pulls the push plate to both sides and then places the detection probe between the two push plates: the push plates are close to each other under the action of the spring to clamp the probe, so that the probe is fixed inside the equipment plate, avoiding the user's long-term use of the probe close to the pressure vessel, which may cause arm fatigue and cause the probe to shake during the inspection of the pressure vessel surface, affecting the accuracy. However, the following deficiencies still exist in actual use: From a practical point of view, when the inspection tool is magnetically adsorbed on the outer surface of the pressure vessel, the adsorption force is large, and it is difficult to manually roll and drive the probe to inspect the surface of the pressure vessel, which affects the inspection efficiency and increases the workload. Moreover, most pressure vessels are large in size, and manual inspection is difficult, which affects their use.

[0004] Therefore, a pressure vessel flaw detection and inspection tool is needed to solve the problems in the prior art that it is difficult to manually roll the probe to inspect the surface of the pressure vessel and that the pressure vessel is large in size and manual inspection is difficult.

[0023] The present invention will be further described below in conjunction with the embodiments.

[0024] See also Figure 1-4 The utility model provides a pressure vessel flaw detection and inspection tool, including a base 1, a fixing mechanism 2, a pressure vessel body 3, a lifting mechanism 4, an inspection mechanism 5 and a detection head 6.

[0026] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that there are two gears 505, which are symmetrically arranged along the center of the connecting shaft 502, the gear 505 is meshed with the rack 506, the U-shaped plate 507 is fixedly connected to the end of the rack 506 away from the connecting shaft 502, the limit bar 508 is symmetrically fixedly connected to the inner left side of the connecting block 501, the U-shaped plate 507 is slidably connected to the outside of the limit bar 508, and the left end of the U-shaped plate 507 extends out of the left side of the connecting block 501;

[0027] By setting the U-shaped plate 507 to slide outside the limiting strip 508, the stability of the movement of the U-shaped plate 507 can be ensured.

[0028] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the fixing plate 509 is fixedly connected to one side of the U-shaped plate 507 close to the center of the connecting shaft 502, the left side of the connecting block 501 is provided with a slide groove 510 adapted to the fixing plate 509, and one side of the fixing plate 509 is provided with an arc surface adapted to the outer surface of the detection head 6;

[0029] When the detection head 6 needs to be disassembled for maintenance, the rotating disk is rotated to drive the gear set 503 to rotate through the transmission shaft 504, and the gear 505 to rotate through the connecting shaft 502. The U-shaped plate 507 is driven to slide on the outside of the limit bar 508 through the racks 506 on both sides, so that the two fixed plates 509 move in the opposite direction, thereby releasing the clamping of the detection head 6 and facilitating the removal of the detection head 6 for maintenance.

[0030] According to the above working process, it can be known that: through the set inspection mechanism 5, the detection head 6 can be quickly disassembled and replaced, which is convenient for the inspection and maintenance of the detection head 6, and the service life of the detection head 6 is increased. There is no need to hold the detection head 6 to inspect the outer surface of the pressure vessel body 3, thereby reducing the workload.

The fixed frame 401 is fixedly connected to the upper right side of the base 1, and a cylinder is installed above the fixed frame 401.

The electric push rod 403 is fixedly connected to the left side of the movable plate 402. The fixing mechanism 2 is composed of a motor 201, a fixed seat 202, a cross plate 204, a threaded rod 205, a clamping plate 206 and an anti-slip layer 207. The output end of the motor 201 is connected to a rotating shaft, the fixed seat 202 is fixedly connected above the rotating shaft, and a cross groove 203 is symmetrically opened on the top surface of the fixed seat 202.

[0033] The anti-slip layer 207 can increase the friction between the clamping plate 206 and the pressure vessel body 3, thereby improving the stability of the pressure vessel body 3 during rotation.

[0034] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the connecting block 501 is fixedly connected to the left side of the electric push rod 403, and the motor 201 is fixedly connected to the inside of the base 1.

[0035] This solution has the following working process: when in use, the pressure vessel body 3 is placed on the inside of the fixed seat 202, and then the threaded rod 205 is rotated in sequence, and the clamping plate 206 is driven to move to one side of the pressure vessel body 3 through the cross plate 204 until the anti-slip layer 207 is close to and presses the pressure vessel body 3, fixes the position of the pressure vessel body 3, and ensures the stability of the pressure vessel body 3 during rotation, and then controls the electric push rod 403 to drive the connecting block 501 and the detection head 6 to approach the pressure vessel body 3 until a position convenient for inspecting the pressure vessel body 3, and then controls the motor 201 to drive the fixed seat 202 to rotate, so that the pressure vessel body 3 rotates, and then the pressure vessel body 3 is inspected by the detection head 6. Since the cylinder drives the movable plate 402 to move up and down, and the electric push rod 403 drives the detection head 6 to move up and down, the outer surface of the pressure vessel body 3 at each height can be inspected, thereby improving the inspection efficiency of the inspection work.

[0036] In summary: through the set inspection mechanism 5, the detection head 6 can be quickly disassembled and replaced, which is convenient for the inspection and maintenance of the detection head 6, and the service life of the detection head 6 is increased, and there is no need to hold the detection head 6 to inspect the outer surface of the pressure vessel body 3, thereby reducing the workload; through the set fixing mechanism 2, the pressure vessel body 3 can be installed above the fixing seat 202 and rotated, so as to facilitate the inspection of various positions on the outer surface of the pressure vessel body 3, improve the inspection accuracy and speed, and facilitate the disassembly and assembly of the pressure vessel body 3, thereby improving work efficiency.
