Description

Axle flaw detection device Technical Field

[0001] The present invention relates to the technical field of wheel axle flaw detection, in particular to a wheel axle flaw detection device. Background Art

[0002] Axles are key components used to connect and support rotating parts, and are commonly found in a wide range of equipment and machinery. Some axles connect wheels, transmit power, and support the weight of vehicles like mountain bikes, racing bicycles, cars, and motorcycles. Other axles connect and support rotating parts in various mechanical devices, such as industrial and agricultural machinery, excavators, and cranes. Other axles also support other rotating parts, such as motors, generators, and windmills.

[0003] Internal defects in axles can seriously compromise the safety and reliability of equipment and systems. Internal defects can reduce the effective cross-sectional area of ​​the axle, thereby reducing its load-bearing capacity and strength. This can lead to the axle being unable to withstand normal stresses and loads during operation, resulting in fracture and failure. Severe internal defects can cause the wheel to fall off. This is extremely dangerous, as a wheel falling off can lead to loss of vehicle control and pose a threat to personnel safety.

[0004] Axle flaw detection equipment uses non-destructive testing technology to detect defects inside the axle to ensure its safety and reliability.

[0005] Chinese patent application number CN202211713831.4 discloses a vertical inspection device for ultrasonic flaw detection of wheel axles. The device comprises a base, on which a servo motor is mounted. The output shaft of the servo motor is connected to the top of a ball screw via a coupling. The bottom of the ball screw is connected to the top of a vertical probe via a screw nut. A radial probe is mounted at the bottom of the vertical probe. Sliders are mounted on both sides of the vertical probe, and the slides are slidably mounted on vertical linear guides. The ball screw rotates via the coupling, driven by the servo motor, driving the vertical probe and radial probe to move up and down. The vertical probe includes a probe body, the bottom end of which is connected to the top of a transition tube, which is connected to the top of the radial probe via a slide tube. A transmitter is installed in the probe body and the transition tube. This invention enables efficient and non-destructive ultrasonic flaw detection of wheel axles of rail vehicles.

[0006] However, some turbine shaft flaw detection devices still have certain shortcomings:

[0007] 1. The wheel axle flaw detection device has the defect of being difficult to clamp and fix;

[0008] 2. The axle flaw detection device lacks an anti-detachment mechanism, which makes it easy for the flaw detector to detach when the clamping mechanism fails, causing damage;

Through the use of the flaw detector body 2 and the probe body 21, the wheel axle can be flaw detected. This is the existing technology and will not be described in detail here. A protective mechanism 3 used in conjunction with the flaw detector body 2 is fixedly installed on the clamping mechanism 1, and an auxiliary mechanism 4 is provided on the clamping mechanism 1 and the protective mechanism 3 for use with each other, and an anti-slip mechanism 5 is provided at the end of the clamping mechanism 1 for use with each other.

[0033] The clamping mechanism 1 includes a T-shaped mounting frame 11, on which a first rotating rod 12 is rotatably connected, and one end of the first rotating rod 12 is fixedly sleeved with a driving gear 13, and the end of the first rotating rod 12 away from the driving gear 13 passes through the T-shaped mounting frame 11 and is fixedly connected to a driving wheel 112 at its end, and a driving rocker 113 is rotatably connected to the driving wheel 112. The cooperation between the driving wheel 112 and the driving rocker 113 provides convenience for the rotation adjustment of the first rotating rod 12, and a driving gear 13 is fixedly installed on the driving gear 13. The first torsion spring 14 is movably mounted on the first rotating rod 12, and one end of the first torsion spring 14 away from the driving gear 13 is fixedly connected to the inner wall of the T-shaped mounting frame 11. A symmetrically distributed transverse guide rod 15 is fixedly installed in the inner cavity of the T-shaped mounting frame 11, and a guide slide 16 is slidably mounted on the transverse guide rod 15. A driven rack 17 is fixedly connected to the guide slide 16, and the driven rack 17 is meshed with the driving gear 13. A first spring 18 and a second spring 19 are movably mounted on the transverse guide rod 15.

[0034] By adopting the above technical solution, when in use, the user can hold the T-shaped mounting frame 11 and rotate the driving rocker 113, thereby driving the driving wheel 112 to rotate, and then driving the first rotating rod 12 to rotate, and further driving the driving gear 13 to rotate, and twisting the first torsion spring 14. When the driving gear 13 rotates, it can synchronously drive the two driven racks 17 to move in the opposite direction, and then drive the two guide slides 16 to move in the opposite direction synchronously, further squeezing the first spring 18 and stretching the second spring 19, and while the guide slide 16 moves, it can pass The connecting slide 110 drives the two positioning clamps 111 to move in opposite directions. When the distance between the two positioning clamps 111 moves to the maximum, the driving rocker 113 stops rotating. Then the user can put the clamping mechanism 1 on the appropriate position on the axle to be tested. Then the user can release the driving rocker 113. At this time, the first torsion spring 14 will drive the driving gear 13 to rotate in the opposite direction, and the first spring 18 and the second spring 19 will drive the corresponding guide slide 16 to reset, thereby driving the two positioning clamps 111 to move in opposite directions until the positioning clamps 111 are tightly clamped on the outside of the axle to be tested.

[0035] The protection mechanism 3 includes a U-shaped guide rod 31, which is fixedly mounted on the positioning splint 111 near the side of the flaw detector body 2, and the U-shaped guide rod 31 has a symmetrical structure. The end of the U-shaped guide rod 31 away from the T-shaped mounting frame 11 is fixedly sleeved with a fixing ring 32, and a third spring 33 is fixedly mounted on the fixing ring 32. The third spring 33 is movably sleeved on the U-shaped guide rod 31, and the end of the third spring 33 is fixedly connected to a guide slider 34, which is slidably sleeved on the U-shaped guide rod 31, and a protection shell 35 is fixedly mounted between the two guide sliders 34. The protection shell 35 can be slidably sleeved on the flaw detector body 2. The auxiliary mechanism 4 includes an auxiliary frame 41 and an auxiliary side plate 42. The auxiliary frame 41 is fixedly mounted on the positioning splint 111 near the flaw detector body 2, and symmetrically distributed auxiliary slides 43 are slidably inserted into the inner cavity of the auxiliary frame 41. A pushing slide 47 is installed, and a symmetrically distributed pushing slide groove 48 is opened on the auxiliary frame 41. The pushing slide 47 is slidably inserted in the pushing slide groove 48. The cooperation between the pushing slide 47 and the pushing slide groove 48 provides convenience for the movement and adjustment of the auxiliary slide plate 43. A fourth spring 44 is fixedly installed between the auxiliary slide plates 43, and the fourth spring 44 is movably engaged in the inner cavity of the auxiliary frame 41. The opposite ends of the auxiliary slide plates 43 are fixedly installed with wedge-shaped positioning blocks 45. The auxiliary side plates 42 are fixedly installed on the protective shell 35, and the auxiliary side plates 42 have a symmetrical structure. The opposite sides of the auxiliary side plates 42 are provided with positioning grooves 46, and the wedge-shaped positioning blocks 45 can be slidably inserted in the positioning grooves 46. A U-shaped grip rod 49 is fixedly installed on the two auxiliary side plates 42, and the outer wall of the U-shaped grip rod 49 is covered with a layer of anti-slip grooves. The setting and use of the anti-slip grooves can increase friction and facilitate operation.

[0036] By adopting the above technical solution, when in use, the user can hold the U-shaped handle 49 and pull it toward the side close to the T-shaped mounting frame 11, so that the two auxiliary side plates 42 can move, and then the protective shell 35 can be driven to move, and the two guide sliders 34 can be further driven to move and stretch the corresponding third spring 33. When the auxiliary side plates 42 come into contact with the wedge-shaped positioning block 45, they will push it to move, thereby driving the two auxiliary slides 43 to move toward each other and squeeze the fourth spring 44. When the protective shell 35 comes into contact with the auxiliary frame 41, the limiting force of the auxiliary side plates 42 on the wedge-shaped positioning block 45 disappears. Afterwards, the fourth spring 44 will drive the wedge-shaped positioning block 45 to reset through the auxiliary slide 43, so that the wedge-shaped positioning block 45 can be inserted into the corresponding positioning groove 46, and then the protective shell 35 can be limited and fixed. After that, the user can loosen the U-shaped grip 49 and open the flaw detector body 2 to perform the detection operation. After the detection operation is completed, the flaw detector body 2 can be closed and the two push slides 47 can be pushed to move toward each other, so that the wedge-shaped positioning block 45 can be separated from the positioning groove 46. After that, the third spring 33 will drive the protective shell 35 to reset, so that the screen of the flaw detector body 2 can be sealed and preserved again.

[0037] The anti-slip mechanism 5 includes a second rotating rod 51, a symmetrically arranged mounting groove 116 is opened at one end of the positioning clamping plate 111 away from the T-shaped mounting frame 11, and the second rotating rod 51 is rotatably inserted into the mounting groove 116, and the second rotating rod 51 is fixedly sleeved with symmetrically distributed winding rollers 52, and the opposite sides of adjacent winding rollers 52 are fixedly installed with second torsion springs 53, the second torsion springs 53 are movably sleeved on the second rotating rod 51, and the opposite ends of adjacent second torsion springs 53 are fixedly connected to the inner wall of the mounting groove 116, away from the flaw detector itself. The two winding rollers 52 of the body 2 are fixedly mounted with symmetrically arranged first anti-slip rods 54, and the two winding rollers 52 close to the flaw detector body 2 are fixedly mounted with U-shaped mounting rods 55, and the U-shaped mounting rods 55 are fixedly mounted with second anti-slip rods 56, and the second anti-slip rods 56 are staggered with the two adjacent first anti-slip rods 54. A traction rope 57 is wound around the winding rollers 52, and the opposite sides of the positioning splint 111 are fixedly mounted with symmetrically arranged first L-shaped rods 58 and second L-shaped rods 510, and the adjacent first L-shaped rods 58 are fixedly mounted with the second L-shaped rods 510. A first pulley 59 is rotatably installed between the two adjacent L-shaped rods 510, and a second pulley 511 is rotatably installed between the adjacent second L-shaped rods 510. The lead-out end of the traction rope 57 is wound around the winding roller 52 and is wound around the first pulley 59 and the second pulley 511, and the end of the traction rope 57 is fixedly connected to the T-shaped mounting frame 11. Since the end of the traction rope 57 is fixedly connected to the T-shaped mounting frame 11, when the positioning splint 111 moves backward, the traction rope 57 will be pulled and limited, thereby driving the winding roller 52 to rotate rapidly, and It can drive the winding roller 52 to rotate quickly more than ninety degrees, so that the second anti-slip rod 56 and the adjacent first anti-slip rod 54 can be quickly rotated ninety degrees, and then completely separated and opened, which further provides convenience for the subsequent clamping installation of the detection device and the wheel axle to be detected. The positioning splint 111 is close to the end of the T-shaped mounting frame 11 and is penetrated by symmetrically distributed auxiliary grooves 117, and the traction rope 57 can movably pass through the auxiliary grooves 117. The setting and use of the auxiliary grooves 117 ensure the normal pulling of the traction rope 57.

[0038] When the first and second anti-slip bars 54 and 56 are completely separated and opened, the clamping mechanism 1 can be placed in a suitable position on the axle to be detected through the opening between the first and second anti-slip bars 54 and 56, and then the user can release the drive. The rocker 113, at this time the two positioning clamps 111 will move towards each other. During this period, the traction force on the traction rope 57 will be gradually removed while the positioning clamp 111 is reset. Then the second torsion spring 53 will drive the corresponding winding roller 52 to rotate in the opposite direction, thereby driving the first anti-detachment rod 54 and the second anti-detachment rod 56 to rotate in the opposite direction, and then the first anti-detachment rod 54 and the second anti-detachment rod 56 can be crossed again, and further can effectively prevent the device from being separated from the wheel axle when the clamping mechanism 1 fails, thereby protecting the flaw detector body 2, and thus avoiding the flaw detector body 2 from being damaged by falling, and further extending the service life of the flaw detector body 2.

[0039] Working principle: When in use, the user can hold the T-shaped mounting frame 11 and rotate the driving rocker 113, thereby driving the driving wheel 112 to rotate, and then driving the first rotating rod 12 to rotate, further driving the driving gear 13 to rotate, and twisting the first torsion spring 14. When the driving gear 13 rotates, it can synchronously drive the two driven racks 17 to move in the opposite direction, and then drive the two guide slides 16 to move in the opposite direction synchronously, further squeezing the first spring 18 and stretching the second spring 19. When the guide slide 16 moves, it can drive the two positioning clamps 111 to move in the opposite direction through the connecting slide 110.

[0040] At the same time, when the positioning splint 111 moves, the traction rope 57 can be pulled, thereby cooperating with the corresponding first pulley 59 and the second pulley 511 to pull the corresponding winding roller 52 to rotate, thereby enabling the winding roller 52 to quickly rotate more than ninety degrees, thereby twisting the corresponding second torsion spring 53 and driving the corresponding first anti-slip rod 54 and the U-shaped mounting rod 55 to rotate gradually, thereby driving the second anti-slip rod 56 to rotate synchronously. When the distance between the two positioning splints 111 moves to the maximum, the driving rocker 113 is stopped, and at this time the first anti-slip rod 54 and the second anti-slip rod 56 are both rotated more than ninety degrees and are completely separated and opened. Then the user can put the clamping mechanism 1 into the appropriate position on the wheel axle to be detected through the opening between the first anti-slip rod 54 and the second anti-slip rod 56, and then the user can release the driving rocker 113. At this time, the first torsion spring 14 will drive The driving gear 13 rotates in the opposite direction, and the first spring 18 and the second spring 19 will drive the corresponding guide slide 16 to reset, thereby driving the two positioning clamps 111 to move in opposite directions until the positioning clamps 111 are tightly clamped on the outer side of the wheel axle to be detected. During this period, while the positioning clamps 111 are reset, the traction force on the traction rope 57 will be gradually removed, and then the second torsion spring 53 will drive the corresponding winding roller 52 to rotate in the opposite direction, thereby driving the first anti-detachment rod 54 and the second anti-detachment rod 56 to rotate in the opposite direction, thereby making the first anti-detachment rod 54 and the second anti-detachment rod 56 cross again, and further effectively preventing the device from being separated from the wheel axle when the clamping mechanism 1 fails, thereby protecting the flaw detector body 2, thereby preventing the flaw detector body 2 from being damaged by falling, and further extending the service life of the flaw detector body 2;

[0041] When the device is fixed, the user can hold the U-shaped handle 49 and pull it toward the side close to the T-shaped mounting frame 11, so that the two auxiliary side plates 42 can move, and then the protective shell 35 can be driven to move, and the two guide sliders 34 can be further driven to move and stretch the corresponding third spring 33. When the auxiliary side plates 42 come into contact with the wedge-shaped positioning block 45, they will push it to move, thereby driving the two auxiliary slides 43 to move toward each other and squeeze the fourth spring 44. When the protective shell 35 comes into contact with the auxiliary frame 41, the limiting force of the auxiliary side plates 42 on the wedge-shaped positioning block 45 disappears, and then the fourth spring 44 will drive the auxiliary slides 43 to move. The wedge-shaped positioning block 45 is reset, so that the wedge-shaped positioning block 45 can be inserted into the corresponding positioning groove 46, and the protective shell 35 can be limited and fixed. Then the user can loosen the U-shaped grip 49 and open the flaw detector body 2 to perform the detection operation. After the detection operation is completed, the flaw detector body 2 can be closed and the two push slides 47 can be pushed to move towards each other, so that the wedge-shaped positioning block 45 can be separated from the positioning groove 46. Then the third spring 33 will drive the protective shell 35 to reset, so that the screen of the flaw detector body 2 can be sealed and stored again. Then the user can loosen the push slide 47 and follow the above steps to remove the device.

[0042] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
