Description

Technical Field

[0001] This application relates to the field of pipe internal hole inspection technology, and in particular to optical inspection equipment for pipe internal hole inspection. Background Technology

[0002] After the pipes are processed in the factory, there may be defects in their quality, which requires the inspection of the inner hole of the pipes.

[0003] To determine whether there are any defects in the inner tube of the steel pipe after processing, the operator needs to observe it with the naked eye under strong light. The traditional method of using a flashlight to inspect the inner cavity of the steel pipe has limitations. Sometimes, due to the lighting, some defects may not be observed, resulting in defective products being released. On the other hand, existing inspection equipment is not convenient to store the rollers during actual use, which leads to insufficient stability during operation, and the moving wheels are easily damaged by gravity. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a light inspection device for inspecting the inner hole of pipes, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a light inspection device for inspecting the inner bore of pipes, comprising a frame, two support columns symmetrically fixedly installed on the top of the frame, and a light box fixedly installed on the top of the two support columns. An acrylic plate is installed on the outer wall of the light box. A lead screw is rotatably connected to the inner bottom of the frame. A bevel gear one is fixedly installed on the outer edge of the lead screw. A bevel gear two meshes with the outer edge of the bevel gear one. One end of a rotating rod is fixedly connected to the outer side of the bevel gear two. A crank handle is fixedly connected to the other end of the rotating rod. A movable plate is threadedly connected to the outer edge of the lead screw. Four rollers are symmetrically fixedly installed on the bottom of the movable plate.

[0006] In a preferred embodiment, a top plate is fixedly installed on the top of the light box, a groove is provided on the outer side of the top plate, a slidably connected rib is provided on the inner wall of the groove, and a light shield is fixedly installed on the outer side of the rib.

[0007] By adopting the above technical solution, the protrusion can be slidably installed onto the inner wall of the groove, thereby allowing the light-shielding plate to be stably installed on the outer wall of the acrylic plate.

[0008] In a preferred embodiment, the top of the top plate has a through hole that extends through the top plate to the inner wall of the protruding strip, and a pin is inserted into the inner wall of the through hole.

[0009] By adopting the above technical solution, the protrusion can be stably positioned on the inner wall of the groove, ensuring that it will not easily slide off. Furthermore, by pulling the pin off the inner wall of the insertion hole, the protrusion can be easily removed from the inner wall of the groove, which in turn facilitates the movement of the light shield away from the outer side of the acrylic sheet, thus exposing the acrylic sheet for pipe inspection.

[0010] In a preferred embodiment, the light-shielding plate is black, the light box is yellow, and a light source is installed on the inner wall of the light box.

[0011] By adopting the above technical solution, the opaque properties of black acrylic sheets can be used to protect the pipes when inspection is not required.

[0012] In a preferred embodiment, a positioning block is fixedly installed on the inner top of the frame, the rotating rod is rotatably connected to the positioning block and the inner wall of the frame, and the crank is installed on the outer side of the frame.

[0013] By adopting the above technical solution, the positioning block can be used to limit the rotation of the rotating rod during rotation, ensuring that the positioning block will not easily deviate from its position during rotation, and thus the power can be stably transmitted by the bevel gear.

[0014] In a preferred embodiment, a base plate is fixedly installed at the inner bottom of the frame, and positioning rings are fixedly installed at the top of the base plate and the inner top of the frame. Both ends of the lead screw are rotatably connected to the inner wall of the positioning rings.

[0015] By adopting the above technical solution, the two positioning rings can limit the two ends of the light-shielding plate, ensuring that the two ends of the lead screw will not easily swing when rotating, and thus can rotate stably in a vertical state.

[0016] In a preferred embodiment, two positioning rods are fixedly installed on the top of the base plate, and the top ends of the two positioning rods are fixedly connected to the inner top of the frame and the bottom of the positioning block, respectively. Two limiting holes are opened through the inner wall of the movable plate, and the two positioning rods are adapted to slide and connect to the inner wall of the two limiting holes.

[0017] By adopting the above technical solution, the moving plate can be limited during vertical movement, ensuring that it can stably drive the four rollers to move up and down, thus preventing friction between the plate and the inner wall of the frame, and ensuring safety.

[0018] In a preferred embodiment, the number of the raised strips and light-shielding plates is three, and the three light-shielding plates are distributed in parallel on the outer wall of the acrylic plate, and the sum of the areas of the three light-shielding plates is the same as the area of ​​the acrylic plate.

[0019] By adopting the above technical solution, the acrylic sheet can be completely shielded, and one of the light-shielding plates can be removed to expose part of the acrylic sheet for pipe inspection, thus facilitating visual inspection by the staff.

[0020] The beneficial effects of this application are:

[0021] 1. The light inspection equipment for inspecting the inner hole of pipes allows the operator to observe the pipes to be inspected by placing the pipes to be inspected on the side of the acrylic plate away from the light box under strong light. This facilitates visual inspection of defects in the inner cavity of the pipes, avoiding the limitations of traditional devices that use flashlights to inspect the inner cavity of steel pipes, where some defects may not be observed due to lighting conditions.

[0022] 2. The light inspection device for inspecting the inner hole of the pipe uses a crank handle to drive the rotating rod and bevel gear two to rotate. The bevel gear two then transmits power to bevel gear one and the lead screw. The rotation of the lead screw drives the moving plate to move upward along the two positioning rods, which in turn allows the four rollers to be housed in the inner cavity of the frame until the bottom of the frame is in complete contact with the ground. This allows the device to be placed stably on the ground without prolonged contact with the ground and being subjected to gravity pressure, thus improving the protection of the rollers and extending their service life.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] ReferenceFigures 1-4 A light inspection device for inspecting the inner bore of pipes includes a frame 1. Two support columns 2 are symmetrically fixedly installed on the top of the frame 1, and a light box 3 is fixedly installed on the top of the two support columns 2. An acrylic plate 20 is installed on the outer wall of the light box 3. A lead screw 9 is rotatably connected to the inner bottom of the frame 1. A bevel gear 10 is fixedly installed on the outer edge of the lead screw 9. A bevel gear 11 meshes with the outer edge of the bevel gear 10. One end of a rotating rod 12 is fixedly connected to the outer side of the bevel gear 11. A crank handle 13 is fixedly connected to the other end of the rotating rod 12. A movable plate 14 is threadedly connected to the outer edge of the lead screw 9. Four rollers 15 are symmetrically fixedly installed on the bottom of the movable plate 14.

[0030] See Figure 2 A top plate 4 is fixedly installed on the top of the light box 3. A groove 5 is provided on the outer side of the top plate 4. A slidable strip 7 is connected to the inner wall of the groove 5. A light shield 8 is fixedly installed on the outer side of the slid strip 7, so that the slid strip 7 can be slidably installed to the inner wall of the groove 5, and the light shield 8 can be stably installed on the outer wall of the acrylic plate 20.

[0031] See Figure 2 The top plate 4 has a through hole that extends through the top plate 4 to the inner wall of the protrusion 7. A pin 6 is inserted into the inner wall of the through hole. The pin 6 can stably position the protrusion 7 on the inner wall of the groove 5, ensuring that it will not easily slide off. Pulling the pin 6 away from the inner wall of the hole can easily remove the protrusion 7 from the inner wall of the groove 5, thereby facilitating the movement of the light shield 8 away from the outside of the acrylic plate 20, so that the acrylic plate 20 is exposed for pipe inspection.

[0032] See Figure 2 The light shield 8 is black, the light box 3 is yellow, and the inner wall of the light box 3 is equipped with a light source, so that the acrylic plate 20 can be protected when the pipe does not need to be inspected by taking advantage of the opaque properties of black.

[0033] See Figure 3 and Figure 4 A positioning block 16 is fixedly installed on the inner top of the frame 1. The rotating rod 12 is rotatably connected to the positioning block 16 and the inner wall of the frame 1. The crank handle 13 is installed on the outer side of the frame 1, so that the positioning block 16 can be used to limit the rotating rod 12 when rotating, ensuring that the positioning block 16 will not easily deviate from its position when rotating, and thus the power can be stably transmitted by the bevel gear 11.

[0034] See Figure 4A base plate 18 is fixedly installed at the bottom inner part of the frame 1. Positioning rings 19 are fixedly installed at the top of the base plate 18 and the top inner part of the frame 1. Both ends of the lead screw 9 are rotatably connected to the inner wall of the positioning rings 19, so that the two positioning rings 19 can limit the two ends of the light shield 8, ensuring that the two ends of the lead screw 9 will not easily swing when rotating, and thus can rotate stably in a vertical state.

[0035] See Figure 3 and Figure 4 Two positioning rods 17 are fixedly installed on the top of the base plate 18, and the top ends of the two positioning rods 17 are fixedly connected to the inner top of the frame 1 and the bottom of the positioning block 16, respectively. Two limiting holes are opened through the inner wall of the moving plate 14. The two positioning rods 17 are adapted to slide and connect to the inner wall of the two limiting holes, so that the moving plate 14 can be limited when moving up and down, ensuring that it can stably drive the four rollers 15 to move up and down, so as not to rub against the inner wall of the frame 1, and at the same time, it can ensure that.

[0036] See Figure 2 There are three convex strips 7 and three light-shielding plates 8, which are distributed in parallel on the outer wall of the acrylic plate 20. The sum of the areas of the three light-shielding plates 8 is the same as the area of ​​the acrylic plate 20. The three light-shielding plates 8 can completely block the acrylic plate 20. At the same time, one of the light-shielding plates 8 can be removed to expose part of the acrylic plate 20 for pipe inspection, which makes it easier for the staff to conduct visual inspection.

[0037] Working principle: When using this device, the four rollers 15 are used to move the device to the location of use. After arriving at the location, the handle 13 is turned to rotate the rotating rod 12 and the second bevel gear 11. The second bevel gear 11 then transmits power to the first bevel gear 10 and the lead screw 9. The rotation of the lead screw 9 drives the moving plate 14 to move upward along the two positioning rods 17. The four rollers 15 can then be stored in the inner cavity of the frame 1 until the bottom of the frame 1 is in complete contact with the ground. The device can then be placed stably on the ground. The pin 6 can then be removed, which pushes the light shield 8 to move the convex strip 7 away from the inner wall of the groove 5, exposing the acrylic plate 20. The pipe to be inspected can then be placed on the side of the acrylic plate 20 away from the light box 3. Under strong light, the operator observes the pipe from the end away from the acrylic plate 20 to visually inspect the defects in the inner cavity of the pipe.
