Description

Technical Field

[0001] This utility model relates to the field of penetrant testing, and in particular to a spraying device for penetrant testing of bars. Background Technology

[0002] Penetrant testing (PT) is one of the earliest nondestructive testing (NDT) methods used in industry. Due to its simplicity and ease of operation, PT is widely used in various fields of modern industry. Due to capillary action, when a penetrant containing fluorescent or colored dye is applied to the surface of a specimen, the penetrant penetrates into various small defects that open onto the surface (these small openings act as capillaries, and the penetration of the penetrant into these defects is equivalent to wetting). After removing excess penetrant from the specimen surface and allowing it to dry, a developer is applied. The penetrant in the defects is then re-adsorbed onto the specimen surface due to capillary action, creating a magnified defect display. The shape, size, and distribution of the defects can then be observed visually.

[0003] In existing penetrant testing processes for rods or pipes, the rods or pipes are typically placed on a flat surface and the test agent is sprayed onto their surface. Since the rods or pipes remain in the same position, there will be areas that are not sprayed, requiring manual rotation to achieve comprehensive spraying. Furthermore, spraying can only be done sequentially, resulting in low efficiency. To address these issues, a spraying device for penetrant testing of rods is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that manual rotation is required to achieve comprehensive spraying, and spraying can only be done sequentially, resulting in low efficiency.

[0005] The present invention adopts the following technical solution:

[0006] A spraying device for penetrant testing of bars includes a housing, a placement rack inside the housing, a storage slot on the placement rack, rubber wheels inside the storage slot, a cover plate on the storage slot, an electric push rod on the placement rack, a transverse frame on the housing, a moving groove on the transverse frame, a support frame inside the moving groove, a limiting groove on the support frame, a spray can on the limiting groove, and a drain port on the housing.

[0007] Furthermore, the box body has an inner cavity, and the two side walls of the inner cavity have elongated grooves. There are two placement racks, which are located inside the inner cavity of the box body and are arranged opposite each other. Both ends of the two placement racks are in contact with the side walls of the inner cavity of the box body. Each placement rack has a protrusion at both ends, which is located in the elongated groove of the box body. Each placement rack has an electric push rod for connecting to the box body. Each placement rack has several storage slots, and the lower end of each storage slot is provided with a rubber wheel. The axle of the rubber wheel is located inside the placement rack and is electrically connected to an external controller.

[0008] Furthermore, the storage slots of the two shelves are arranged opposite each other, with each pair of corresponding storage slots located on the same straight line and parallel to the two adjacent storage slots.

[0009] Furthermore, the two ends of the placement rack have slots, the two ends of the cover plate have buckles, and the cover plate has several positioning plates, which are located between the two storage slots of the placement rack.

[0010] Furthermore, the box body has slots on both sides, and a first screw rod connected to the motor is located in the slot. A transverse frame is installed in the slot, and the transverse frame is threadedly connected to the first screw rod.

[0011] Furthermore, the upper end of the transverse frame is provided with a moving groove, and a second screw connected to the motor is located in the moving groove. The support frame is located in the moving groove and is threadedly connected to the second screw.

[0012] Furthermore, the lower end of the support frame is provided with a limiting groove, and the limiting groove has a protruding semi-circular groove.

[0013] Furthermore, one end of the spray can rests against the support frame, and the other end is held in place by the slot of the limiting groove, with the spray can facing vertically towards the box body;

[0014] Furthermore, a drain port is provided at the bottom of the inner cavity of the box and extends out of the box. The drain port is located between two placement racks and has a valve for controlling the drainage.

[0015] The beneficial effects of this utility model are:

[0016] The device utilizes rubber wheels to drive the rotation of the rods and the two-dimensional movement of the spray can, replacing manual rod rotation and reducing manual intervention and labor intensity, making it suitable for batch testing. The uniform rotation of the rods, combined with the lateral and longitudinal movement of the spray can, ensures that every surface is covered by the penetrant, avoiding omissions caused by traditional manual spraying and improving the accuracy of test results. The electric push rod can adjust the position of the placement rack to accommodate rods of different sizes. The design of the cover plate and positioning plate can fix the rods to prevent shaking during testing and ensure testing stability. The drain port is located between the two placement racks, which can collect test waste liquid in a timely manner. With valve control, it is convenient for subsequent waste liquid recycling or treatment, keeping the inside of the device clean. Attached Figure Description
