Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, and specifically relates to a central exposure bracket for non-destructive testing of pressure vessels. Background Art

[0002] A pressure vessel is a sealed container that can withstand pressure. Pressure vessels are extremely widely used and play an important role in many sectors such as industry, civil use, military, and many fields of scientific research. Among them, they are most used in the chemical industry and petrochemical industry. Pressure vessels used in the petrochemical industry alone account for about 50% of the total number of all pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used in processes such as heat transfer, mass transfer, and reaction, as well as for storing and transporting pressurized gases or liquefied gases; they are also widely used in other industrial and civil fields, such as air compressors. Auxiliary machines (coolers, buffers, oil-water separators, gas storage tanks, evaporators, liquid coolant storage tanks, etc.) of various special compressors and refrigeration compressors are all pressure vessels, and pressure vessels need to be inspected before use to prevent damaged pressure vessels.

Content of the Utility Model

[0004] The purpose of the utility model is to provide a central exposure bracket for non-destructive testing of pressure vessels to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A central exposure support for non-destructive testing of pressure vessels, including a body. A chute is provided at the top end of the body. An activity block is movably arranged inside the chute. A plurality of pulleys are arranged on both sides of the bottom end of the activity block. Installation grooves are provided on both sides of the top end of the activity block. Motors are arranged on both sides inside the installation grooves. A gear is fixedly arranged at the output end of the motor. A plurality of auxiliary blocks are arranged at the top end of the activity block. The plurality of auxiliary blocks are movably provided with a support block through a rotating shaft. One end of the support block is movably provided with a runner through a rotating shaft. A tooth groove is fixedly arranged at one end of the support block. The tooth groove meshes with the gear. A threaded groove is provided on one side of the top end of the activity block. A positioning mechanism is arranged inside the threaded groove.

[0007] Preferably, the positioning mechanism includes a threaded rod, a clamping block and a handle. The threaded rod is movably arranged inside the threaded groove. The clamping block is fixedly arranged at the bottom end of the threaded rod. The handle is fixedly arranged at the top end of the threaded rod.

[0008] Preferably, a plurality of fixing holes are arranged on four sides of the body.

[0009] Preferably, auxiliary grooves are provided on both sides of the bottom end of the chute. The pulley is located inside the auxiliary groove at the bottom end of the body.

[0010] Preferably, a limiting groove is provided at the bottom end inside the body. A limiting block is fixedly arranged at the bottom end of the activity block. The limiting block is located inside the limiting groove.

[0011] Preferably, a rubber pad is arranged on the surface of the runner.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For this central exposure support for non-destructive testing of pressure vessels, during use, considering that some pressure vessels to be tested are large and heavy, it is very difficult to rotate them during the testing process to perform comprehensive testing. Therefore, installation grooves are provided at the top end of the activity block. Motors are arranged on both sides inside the installation grooves. A gear is fixedly arranged at the output end of the motor. A rack meshing with the gear is fixedly arranged at one end of the support block for supporting the pressure vessel. At the same time, a runner is movably arranged at one end of the support block through a rotating shaft. When the pressure vessel is placed on the support, the pressure vessel contacts the runner. Through the setting of the rotating shaft, the pressure vessel can be rotated to achieve comprehensive testing. At the same time, by arranging a gear meshing with the rack and a motor at one end of the support block, the motor can be turned on during use. The gear rotates and moves the meshing rack. At this time, one end of the support block will be lifted under the fixation of a plurality of auxiliary blocks, realizing the approach of the distances at both ends of the support block. At this time, the distance between the runners can be adjusted to place pressure vessels of different sizes, without reinstalling the support according to pressure vessels of different specifications, reducing the use cost and improving the use effect.

[0014] 2. The central exposure bracket for non-destructive testing of a pressure vessel is inconvenient to use during the process. Some pressure vessels are relatively long, and during the exposure testing process, full-round inspection is required. At this time, the testing instrument can only detect one end of the pressure vessel, and it is necessary to move the testing instrument along the pressure vessel, which is rather inconvenient. Therefore, a chute is provided at the top end of the machine body, and an auxiliary groove is provided at the bottom end inside the chute. A number of pulleys are fixedly arranged on both sides of the bottom end of the movable block, and the number of pulleys is located inside the auxiliary groove. During use, the movable block can be directly moved, and the movable block will move along the chute. During the movement of the movable block, the pressure vessel will be driven to move. At this time, there is no need to move the testing instrument, preventing damage to the instrument during the movement process and causing inconvenience in testing. At the same time, through the above design, it can also ensure full-round inspection of the pressure vessel, preventing detection dead angles during the inspection process, resulting in unqualified pressure vessels and certain potential safety hazards.

On both sides of the bottom end of the movable block 3, several pulleys 4 are fixedly provided, and the several pulleys 4 are located inside the auxiliary groove 17. During use, the movable block 3 can be directly moved, and the movable block 3 will move along the sliding groove 2. The movable block 3 will drive the pressure vessel to move during the movement process. At this time, there is no need to move the testing instrument, preventing damage to the instrument during the movement process and causing inconvenient testing. At the same time, through the above design, it can also ensure comprehensive testing of the pressure vessel, preventing detection dead angles during the testing process, resulting in unqualified pressure vessels and potential safety hazards.
