Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to an optomechanical fixing device. Background Technology

[0002] During pipeline operation, defects in materials, welding, construction, corrosion, and external interference can cause stress concentration, deformation, corrosion thinning, perforation, cracks, and welding defects, leading to decreased pipeline transport efficiency and even safety accidents such as leakage of the transported medium. To prevent pipeline accidents, non-destructive testing techniques are commonly used to detect pipeline defects.

[0003] CN202320895164X provides a detection device for small-diameter pipes. It uses a combination of magnets and Velcro straps to fix an optical engine and detector to the pipe. Specifically, the optical engine is fixed as follows: the optical engine fixing fixture includes an optical engine fixing plate, two clamps, and a magnet mounting plate. The two clamps are coaxially arranged and fixed to the left and right sides of the optical engine fixing plate, respectively. Each clamp has three first locking screws. After the optical engine is inserted through the clamp, it is locked in place using the first locking screws. Two columns are fixed to one side of the magnet mounting plate, passing through the upper and lower ends of the optical engine fixing plate, respectively, and are fixed by multiple second locking screws.

[0004] The above solution has the following problems: after the optical engine is inserted into the clamp, the six first locking screws need to be tightened manually, which is cumbersome, inefficient, and cannot guarantee that the optical engine is fixed in the center of the clamp.

The arc-shaped outer wall of the outer ring is fixedly connected to the optical engine fixing plate. The inner side of the outer ring is close to the outer side of the inner ring. The inner side of the outer ring is provided with multiple sliding grooves. A slider is slidably installed in the sliding groove. The sliding direction of the slider is towards the center of the outer ring. The slider is connected to the corresponding clamping plate. When the multiple clamping plates are brought together, they are used to clamp the optical engine. The inner side of the slider is provided with a guide post. The inner ring is circumferentially distributed with multiple inclined grooves.

[0012] Furthermore, the optical engine mounting plate is designed in a cross shape.

[0013] Furthermore, the inner wall of the plywood is provided with a rubber layer.

[0021] Figure 4 A top view of the clamping mechanism and the power mechanism is shown. Detailed Implementation

[0022] like Figure 1 As shown, this embodiment provides an optomechanical fixing device, including an optomechanical fixing plate 1, a power mechanism 3, and two clamping mechanisms 4.

[0023] Specifically, such as Figure 1 , Figure 3As shown, the optical engine fixing plate 1 is configured as a cross shape, and two clamping mechanisms 4 are symmetrically arranged on both sides of the optical engine fixing plate 1. Each clamping mechanism 4 includes three clamping plates 43 and an outer ring 41 and an inner ring 42 arranged coaxially. The arc-shaped outer wall of the outer ring 41 is fixedly connected to the optical engine fixing plate 1 by two bolts. The inner side of the outer ring 41 is close to the outer side of the inner ring 42. Three sliding grooves 411 are evenly provided circumferentially on the inner side of the outer ring 41. The long axis of the sliding grooves 411 points to the center of the outer ring 41, and the outer end of the sliding grooves 411 penetrates the arc-shaped outer wall of the outer ring 41. The inner end of the sliding grooves 411 penetrates the arc-shaped inner wall of the outer ring 41. A slider 412 is slidably arranged in the sliding grooves 411. Figure 4 The clamping plate 43 is located in the through hole at the center of the outer ring 41 and the inner ring 42. The slider 412 is connected to the corresponding clamping plate 43. The inner side of the slider 412 is close to the outer side of the inner ring 42. The inner side of the slider 412 is provided with a guide post 413. The inner ring 42 has three inclined grooves 421 distributed around its circumference. The inclined grooves 421 penetrate the inner ring 42. Along the direction from one end of the inclined groove 421 to the other end, the distance between it and the inner ring 42 gradually increases or decreases. The guide post 413 is matched in the corresponding inclined groove 421.

[0024] Specifically, such as Figure 1 , Figure 3 As shown, the two inner rings 42 are fixedly connected by a reinforcing plate 5. The power mechanism 3 includes a motor 31, a gear 32 and an arc rack 33. The motor 31 is fixedly mounted on the optical engine mounting plate 1. The output shaft of the motor 31 is connected to the gear 32. The arc rack 33 is fixedly mounted on the reinforcing plate 5. The optical engine mounting plate 1 is provided with a clearance window 11. The gear 32 and the arc rack 33 mesh with each other at the clearance window 11.

[0025] The method for fixing the optical engine is as follows: the optical engine is inserted into the two inner rings 42, or in other words, into the two outer rings 41; the motor 31 drives the gear 32, causing the arc-shaped rack 33 to rotate, and the reinforcing plate 5 and the two inner rings 42 rotate accordingly. Since the slider 412 is confined within the slide groove 411, it can only slide along the slide groove 411. Therefore, when the inner ring 42 rotates, it will squeeze the guide post 413. When the guide post 413 moves along the inclined groove 421, the slider 412 slides along the slide groove 411, thereby causing the three clamping plates 43 to come together until the clamping plates 43 clamp the optical engine. In order to prevent the clamping plates 43 from damaging the outer wall of the optical engine, this embodiment has a rubber layer on the inner wall of the clamping plates 43.

[0026] The device provided in this embodiment can quickly clamp the optical engine and ensure that the optical engine is located at the exact center of the inner ring 42. This embodiment can also be applied to optical engines of various specifications, and has a wide range of applications.

[0027] To further improve stability, such as Figure 3 , Figure 4 As shown, the two outer rings 41 are fixedly connected by three straight rods 414, and all three straight rods 414 are tangent to the inner ring 42.

[0028] To facilitate adjustment of the position of the optical engine and the pipeline, such as Figure 2 As shown, the device also includes a magnet mounting plate 2. Two parallel columns 21 are provided on one side of the magnet mounting plate 2. The two columns 21 pass through the upper and lower ends of the optical engine fixing plate 1 respectively and are fixed by several locking screws 22. The outer ring 41 is located within the range of the two columns 21 to prevent the columns 21 from obstructing the optical engine.

[0029] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
