Description

Technical Field

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

[0002] For important industrial fields, pipes and bars need to undergo 100% non-destructive testing before use to ensure that the pipes and bars are used safely.

[0003] For large quantities of heavy tubes and bars, in order to ensure comprehensive flaw detection, the parts need to be turned over for inspection. The fixed V-block cooperates with the crane to realize the turning of the tubes and bars by manpower. This method is inefficient, labor-intensive for workers, and has safety hazards, which may cause damage to the workpiece or even casualties. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a flaw detection platform to reduce the repetitive work of personnel, reduce labor intensity, improve work efficiency and eliminate the risks.

[0005] The purpose of the utility model is achieved in this way:

[0006] A flaw detection platform comprises a mounting platform, a rotating shaft, a roller and a motor. Two rotating shafts are arranged on the mounting platform in parallel on the left and right sides. Both ends of the rotating shafts are supported by bearing seats. Rollers are fixed on the rotating shafts. The two rollers are symmetrically arranged in the axial direction of the rotating shafts. One of the rotating shafts is driven to rotate by the motor. A workpiece is arranged between the two rotating shafts, and each roller is in contact with the circumferential surface of the workpiece.

[0007] Preferably, the distance between the two rotating shafts is adjustable, the bearing seat is fixed on the slide, and a positive and negative screw rod is provided between the two slides on the same side of the front and rear sides. The positive and negative screw rod drives the slides to move closer to or away from each other, and the slide is slidably arranged on the mounting plate of the mounting table.

[0008] Preferably, the slide seat is connected to the mounting plate via bolts, and the mounting plate is provided with slide grooves corresponding to the bolts.

[0009] Preferably, a handwheel is provided at one end of the forward and reverse screw rods, and the two handwheels are arranged on the same radial side of the workpiece.

[0010] Preferably, the middle polished rod portion of the positive and negative threaded rod is supported by a support seat, and the support seat is fixed on the mounting plate.

[0011] The beneficial effects of the utility model are:

[0012] It can effectively reduce the time and danger of hoisting and flipping. Only a small number of people are needed to complete the layout work in the same time, and it also reduces the damage to the workpiece that may be caused during the flaw detection process;

[0013] The workpiece is supported between two rotating shafts. The motor drives one rotating shaft to rotate. The roller contacts the workpiece. The friction force drives the workpiece to rotate smoothly. Cooperating with relevant personnel to complete the flaw detection, it greatly improves work efficiency and reduces safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model.

[0015] Among them: mounting platform 1; mounting plate 1.1; slide groove 1.1.1; positive and negative threaded screw 2; hand wheel 2.1; rotating shaft 3; roller 4; motor 5; slide seat 6; bearing seat 7; support seat 8. DETAILED DESCRIPTION

[0016] See also Figure 1 The utility model relates to a flaw detection platform, including a mounting platform 1, positive and negative threaded screws 2, a rotating shaft 3, a roller 4, a motor 5, a slide seat 6 and a bearing seat 7. Two rotating shafts 3 are arranged on the mounting platform 1 in parallel, and both ends of the rotating shaft 3 are supported by the bearing seat 7. Rollers 4 are fixed on the rotating shaft 3, and the two rollers 4 are symmetrically arranged in the axial direction of the rotating shaft 3. One of the rotating shafts 3 is driven to rotate by the motor 5. The workpiece is arranged between the two rotating shafts 3, and each roller 4 is in contact with the circumferential surface of the workpiece.

[0017] The distance between the two rotating shafts 3 is adjustable, and the bearing seat 7 is fixed on the slide 6. A positive and negative screw rod 2 is provided between the two slides 6 on the same side of the front and rear sides. The positive and negative screw rod 2 drives the slides 6 to move closer to or away from each other. The slide 6 is slidably set on the mounting plate 1.1 of the mounting platform 1. The slide 6 is connected to the mounting plate 1.1 by bolts. The mounting plate 1.1 is provided with a slide groove 1.1.1 corresponding to the bolt. The bolt drives the slide 6 and the bearing seat 7 thereon to move along the slide groove 1.1.1.

[0018] A handwheel 2.1 is provided at one end of the positive and negative threaded rod 2. The two handwheels 2.1 are arranged on the same radial side of the workpiece, so that the operator can adjust the handwheel 2.1 synchronously, thereby adjusting the distance between the two rotating shafts 3 to adapt to workpieces of different diameters.

[0019] The middle polished rod part of the forward and reverse threaded rod 2 is supported by a support seat 8, and the support seat 8 is fixed on the mounting plate 1.1. The support seat 8 supports the forward and reverse threaded rod 2, thereby improving the overall stability.

[0020] The workpiece is hoisted between the two rotating shafts 3. The circumferential surface of the workpiece contacts with four rollers 4. The workpiece can be stably self-locked by its own weight without the risk of rolling off. The motor 5 drives the rotating shaft 3 to rotate. The rollers 4 contact with the workpiece. The friction force drives the workpiece to rotate smoothly. Cooperate with relevant personnel to complete the flaw detection.

[0021] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
