Description

Technical Field

[0001] This utility model belongs to the field of sensor detection technology, and specifically relates to a flexible lifting mechanism for an adsorption sensor. Background Technology

[0002] When a vibration sensor is used for sampling, one end of the sensor needs to be fixed to the object being measured by means of magnetic attraction, etc. In order to avoid affecting the sampling effect, the other end needs to be free. When the sensor is working in automated equipment, it needs to have the function of automatic adsorption and detachment. Since the sensor is adsorbed onto the object being measured by a magnet, when the magnet gradually approaches the object being measured, it suddenly and quickly adsorbs onto the object being measured. This causes the impact force when the sensor is attached to the object being measured to be too large. At this time, the sensor needs to self-correct for a long time to reach the working condition, which affects the sampling efficiency of the equipment. Utility Model Content

[0003] This invention provides a flexible lifting mechanism for an adsorption sensor, which solves the technical problem that the impact force of the current vibration sensor is too large when it is adsorbed onto the object being measured, causing the sensor to require a long time to self-correct, thus affecting the sampling efficiency.

[0004] This utility model is achieved through the following technical solution: a flexible lifting mechanism for an adsorption sensor, comprising a base, a lifting sleeve, a sensor, an adsorption electromagnet, and a release electromagnet, wherein the lifting sleeve is slidably installed on the base; the sensor is slidably installed inside the lifting sleeve, with one end of the sensor for measurement extending out of the lifting sleeve, and the lifting sleeve moves to synchronously drive the sensor to move; the adsorption electromagnet is installed at the end of the sensor away from the lifting sleeve; the release electromagnet is installed on the outer wall of the lifting sleeve and located at the end of the lifting sleeve close to the sensor.

[0005] Optionally, it also includes a lifting member, which is mounted on the base and located on one side of the lifting sleeve. The axial direction of the lifting member is parallel to the lifting sleeve. The lifting member is connected to the end of the lifting sleeve away from the sensor to drive the lifting sleeve to move.

[0006] Optionally, it also includes an iron sheet, which is installed on the side of the adsorption electromagnet close to the sensor. The iron sheet is used to attract the detaching electromagnet, thereby driving the sensor to reset.

[0007] Optionally, it also includes a conductive sheet mounted on the base, the conductive sheet being arc-shaped, and one side of the conductive sheet abutting against the test piece.

[0008] Optionally, it also includes a spring, one end of which is mounted on the base and the other end of which is mounted on the conductive sheet. The conductive sheet is separated from the test piece, and in the reset state, the spring drives the conductive sheet to reset.

[0009] Optionally, the lifting sleeve has a cavity, and the sensor is slidably installed in the cavity. The cavity includes a first section and a second section. The first section is cylindrical, and the diameter of the second section gradually increases from the end of the lifting sleeve near the base to the end away from the base.

[0010] Optionally, the sensor includes a sensor housing and a sensor body, wherein the sensor housing is installed inside the cavity, and the diameter of the sensor housing gradually increases from the end of the sensor housing near the base to the end away from the base; the sensor body is installed inside the sensor housing.

[0011] Optionally, the sensor housing is a structural component made of insulating material.

[0012] Optionally, it also includes an in-situ sensor mounted on the base, the in-situ sensor being used to detect the position of the iron sheet.

[0013] Optionally, the base has a through hole, and the lifting sleeve is slidably installed in the through hole.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This utility model provides a flexible lifting mechanism for an adsorption sensor, comprising a base, a lifting sleeve, a sensor, an adsorption electromagnet, and a release electromagnet. The lifting sleeve is slidably mounted on the base; the sensor is slidably mounted inside the lifting sleeve, with one end of the sensor used for measurement extending out of the lifting sleeve; the lifting sleeve moves to synchronously drive the sensor to move; the adsorption electromagnet is mounted at the end of the sensor away from the lifting sleeve; and the release electromagnet is mounted on the outer wall of the lifting sleeve and located at the end of the lifting sleeve closer to the sensor.

[0016] With the above structure, the flexible lifting mechanism for an adsorption sensor provided by this utility model, when sampling the test piece is required, firstly, the lifting sleeve moves the sensor towards the test piece, bringing the sensor close to it. Then, the adsorption electromagnet is energized, causing the sensor to move along the axial direction of the lifting sleeve towards the test piece under the magnetic force of the electromagnet and adsorb onto it. The detachment electromagnet is de-energized, and the sensor samples the test piece. After the sensor finishes sampling, the lifting sleeve moves closer to the sensor, the adsorption electromagnet is de-energized, causing the electromagnet to detach from the test piece. The detachment electromagnet is then energized, adsorbing the sensor and moving it closer to the lifting sleeve. Finally, the lifting sleeve moves away from the test piece, and the sensor resets with the lifting sleeve, completing the sampling process. Therefore, the flexible lifting mechanism of this adsorption sensor moves the sensor by lifting the sleeve, bringing the sensor close to the workpiece, and then adsorbs it onto the workpiece by an adsorption electromagnet. This reduces the distance the adsorption electromagnet needs to be attached to the workpiece, thereby reducing the impact on the sensor caused by excessively fast sensor movement, reducing the sensor calibration time, and enabling the sensor to sample the workpiece better, thus improving the efficiency of the application.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] This utility model provides a flexible lifting mechanism for an adsorption sensor, solving the technical problem described herein. The flexible lifting mechanism includes a base 1, a lifting sleeve 2, a sensor 3, an adsorption electromagnet 4, and a release electromagnet 5, wherein:

[0029] The base 1 is used to fix it under the test piece 11 to provide a stable mounting position so that other components can be mounted on the base 1.

[0030] The lifting sleeve 2 is slidably mounted on the base 1. The lifting sleeve 2 slides to adjust the distance between the lifting sleeve 2 and the measured part 11.

[0031] The sensor 3 is slidably installed inside the lifting sleeve 2. The end of the sensor 3 used for measurement extends out of the lifting sleeve 2 so as to be fixed on the test piece 11 for sampling. The lifting sleeve 2 moves, thereby synchronously driving the sensor 3 to move closer to or away from the test piece 11. The sensor 3 slides along the lifting sleeve 2, thereby separating the sensor 3 from the lifting sleeve 2, thereby reducing the impact of the vibration of the base 1 on the sampling of the sensor 3.

[0032] The electromagnet 4 is installed at the end of the sensor 3 away from the lifting sleeve 2. The electromagnet 4 is used to drive the sensor 3 to be attracted to the test piece 11 when the power is turned on, so as to fix the sensor 3 to the test piece 11 so that the sensor 3 can sample the test piece 11. When the electromagnet 4 is attracted to the test piece 11, the electromagnet 4 drives the sensor 3 to slide away from the lifting sleeve 2 along the axial direction of the lifting sleeve 2.

[0033] The detachment electromagnet 5 is installed on the outer wall of the lifting sleeve 2 and located at the end of the lifting sleeve 2 near the sensor 3. The detachment electromagnet 5 is used to reset the sensor 3 when the adsorption electromagnet 4 is de-energized and the detachment electromagnet 5 is energized after the sample of the test piece 11 is completed.

[0034] With the above structure, when the flexible lifting mechanism of the adsorption sensor 3 provided by this utility model needs to sample the test piece 11, firstly, the lifting sleeve 2 drives the sensor 3 to move towards the test piece 11, so that the sensor 3 is close to the test piece 11. Then, the adsorption electromagnet 4 is energized, so that the sensor 3 moves along the axial direction of the lifting sleeve 2 towards the test piece 11 under the action of the magnetic force of the adsorption electromagnet 4 and is adsorbed onto the test piece 11. The detachment electromagnet 5 is de-energized, and the sensor 3 samples the test piece 11. After the sensor 3 finishes sampling, the lifting sleeve 2 moves towards the sensor 3, the adsorption electromagnet 4 is de-energized, so that the adsorption electromagnet 4 is detached from the test piece 11. The detachment electromagnet 5 is energized, so that the sensor 3 moves towards the lifting sleeve 2. Finally, the lifting sleeve 2 moves away from the test piece 11, and the sensor 3 is reset with the lifting sleeve 2, completing the sampling. Therefore, the flexible lifting mechanism of the adsorption sensor 3 moves the sensor 3 by lifting the sleeve 2, so that the sensor 3 is close to the test piece 11, and then adsorbs onto the test piece 11 by the adsorption electromagnet 4. This reduces the distance when the adsorption electromagnet 4 is adsorbed onto the test piece 11, thereby reducing the impact on the sensor 3 caused by the excessively fast movement speed, reducing the correction time of the sensor 3, and thus enabling the sensor 3 to better sample the test piece 11, improving the sampling efficiency.

[0035] An optional implementation of this embodiment is as follows: To facilitate the movement of the lifting sleeve 2, the flexible lifting mechanism of the adsorption sensor 3 further includes a lifting member 6. The lifting member 6 is mounted on the base 1 and is connected to the lifting sleeve 2 in a transmission manner. The lifting member 6 can be a cylinder, hydraulic cylinder, electric push rod, etc. The lifting member 6 is mounted on one side of the lifting sleeve 2, and the axial direction of the lifting member 6 is parallel to the lifting sleeve 2. In this way, the lifting member 6 can utilize the space between the lifting sleeve 2 and the base 1 to reduce the height occupied by the flexible lifting mechanism of the adsorption sensor 3. Specifically, the lifting member 6 has a fixed end and a telescopic end. The fixed end of the lifting member 6 is mounted on the base 1, and the telescopic end of the lifting member 6 is connected to the end of the lifting sleeve 2 away from the sensor 3. When the lifting member 6 extends, it drives the lifting sleeve 2 to move towards the sensor 3. When the lifting member 6 shortens, it drives the lifting sleeve 2 to move away from the sensor 3.

[0036] An optional implementation of this embodiment is as follows: To facilitate the resetting of the sensor 3 by the detachment electromagnet 5, the flexible lifting mechanism of the adsorption sensor 3 further includes an iron plate 7. The iron plate 7 is installed on the side of the adsorption electromagnet 4 near the sensor 3. The iron plate 7 is used to adsorb the detachment electromagnet 5, thereby driving the sensor 3 to reset. Specifically, after the sensor 3 finishes sampling, the lifting sleeve 2 moves towards the sensor 3, the adsorption electromagnet 4 is de-energized, causing the adsorption electromagnet 4 to detach from the measured object 11, the detachment electromagnet 5 is energized to adsorb the iron plate 7, causing the iron plate 7 to move closer to the detachment electromagnet 5. At the same time, the iron plate 7 drives the sensor 3 and the adsorption electromagnet 4 to move towards the lifting sleeve 2, thereby resetting the sensor 3.

[0037] An optional implementation of this embodiment is as follows: In order to reduce the impact of static voltage on the sensor, the flexible lifting mechanism of the adsorption sensor 3 further includes a conductive sheet 8. The conductive sheet 8 is mounted on the base 1 and grounded. The conductive sheet 8 is arc-shaped to give it better elasticity. The conductive sheet 8 has an inner arc side and an outer arc side that are arranged opposite to each other. The outer arc side of the conductive sheet 8 is used to abut against the test piece 11, thereby grounding the test piece 11 and reducing the impact of static voltage on the sensor 3. Specifically, when sampling the bearing of a train wheelset, the sensor 3 needs to be attached to a fixed bearing. At this time, the friction between the rubber wheel of the drive wheel and the wheel will generate static voltage, which will affect the sampling of the sensor 3 and may even break down the circuit of the sensor 3. By grounding the bearing through the conductive sheet 8, the sensor 3 can be better protected. The arc-shaped conductive sheet 8 can adapt to bearings of different diameters.

[0038] An optional implementation of this embodiment is as follows: In order to better reset the conductive sheet 8, the flexible lifting mechanism of the adsorption sensor 3 further includes a spring 9. One end of the spring 9 is installed on the base 1, and the other end is installed on the side of the conductive sheet 8 that is used to abut against the measured object 11. When the conductive sheet 8 contacts the measured object 11, the spring 9 applies a force to the conductive sheet 8 in the direction of the measured object 11. When the conductive sheet 8 separates from the measured object 11, the spring 9 drives the conductive sheet 8 to reset in the reset state, so that the conductive sheet 8 can abut against the measured object 11 when used again.

[0039] An optional implementation of this embodiment is as follows: The lifting sleeve 2 has a cavity, and the sensor 3 is slidably installed within the cavity. The cavity includes a first section 21 and a second section 22. The first section 21 is cylindrical, and the diameter of the second section 22 gradually increases from the end of the lifting sleeve 2 near the base 1 to the end away from the base 1. When sampling the measured object 11, firstly, the lifting sleeve 2 moves the sensor 3 towards the measured object 11, bringing the sensor 3 close to the measured object 11. Then, the electromagnet 4 is energized, causing the sensor 3 to move along the axis of the lifting sleeve 2 under the magnetic force of the electromagnet 4. The sensor moves towards the test piece 11 and adheres to it. The electromagnet 5 is de-energized, and the lifting sleeve 2 moves away from the sensor 3, thereby separating the sensor 3 from the lifting sleeve 2. This reduces the impact of the vibration of the base 1 on the sampling of the sensor 3. The sensor 3 samples the test piece 11. After sampling the test piece 11, the sensor 3 moves back into the second section 22. The diameter of the second section 22 gradually increases from the end of the lifting sleeve 2 near the base 1 to the end away from the base 1, making the cavity area larger when the sensor 3 enters, so that the sensor 3 can enter the cavity more easily.

[0040] An optional implementation of this embodiment is as follows: The sensor 3 includes a sensor housing 31 and a sensor body 32. The sensor housing 31 is installed in the cavity. The diameter of the sensor housing 31 gradually increases from the end of the sensor housing 31 closest to the base 1 to the end furthest from the base 1. Since the working environment of the sensor 3 is a vibration environment, the sensor 3 may shift during use. To prevent the sensor 3 from being out of its original position and damaged when the lifting sleeve 2 is lifted, the above structure is adopted to ensure that the sensor housing 31 can slide into the sleeve through the inclined surface of the second section 22 and be attracted by the detachment electromagnet 5. The stroke of the cylinder ensures that the tail end of the sensor housing 31 will not leave the lifting sleeve 2. After sampling the measured object 11, when the sensor 3 moves back into the second section 22, the end of the sensor housing 31 with a smaller diameter enters the end of the second section 22 with a larger diameter first, making it easier for the sensor housing 31 to enter the cavity. The sensor body 32 is installed inside the sensor housing 31. The sensor housing 31 can protect the sensor body 32 and reduce the loss of the sensor body 32.

[0041] An optional implementation of this embodiment is as follows: The sensor housing 31 is a structural component made of insulating material. When the sensor 3 samples the measured object 11, the electrical signals generated by other devices or the flexible lifting mechanism of the adsorption sensor 3 will cause significant interference to the sensor 3. By using the insulating sensor housing 31 to shield the interference signals, the influence of other interference signals on the sensor 3 can be reduced, thereby better protecting the sensor 3.

[0042] An optional implementation of this embodiment is as follows: It also includes an in-situ sensor 10, which is mounted on the base 1. The in-situ sensor 10 is used to detect the position of the iron piece 7. After the sample of the test piece 11 is completed, the detached electromagnet 5 attracts the iron piece 7 and drives the sensor 3 to reset. When the in-situ sensor 10 senses the signal and detects that the iron piece 7 has been reset, it indicates that the sensor 3 has been fully returned to its original position, so as to facilitate the next step.

[0043] An optional implementation of this embodiment is as follows: A through hole is provided on the base 1, and the lifting sleeve 2 is slidably installed in the through hole. By moving the lifting sleeve 2 in the through hole, the inner wall of the through hole limits the lifting sleeve 2, which can reduce the radial displacement of the lifting sleeve 2, thereby allowing the sensor 3 to better contact the measured part 11.

[0044] With the above structure, the flexible lifting mechanism of the adsorption sensor 3 provided by this utility model, when sampling the test piece 11 is required, firstly, the lifting member 6 extends, thereby driving the lifting sleeve 2 to move towards the sensor 3. The lifting sleeve 2 drives the sensor 3 to move towards the test piece 11, bringing the sensor 3 close to the test piece 11. At the same time, the outer arc side of the conductive sheet 8 is used to abut against the test piece 11, thereby grounding the test piece 11 and reducing the influence of static voltage on the sensor 3. Then, the adsorption electromagnet 4 is energized, causing the sensor 3 to move along the axial direction of the lifting sleeve 2 towards the test piece 11 under the action of the magnetic force of the adsorption electromagnet 4 and adsorb onto the test piece 11. When the detachment electromagnet 5 is de-energized, the lifting sleeve 2 moves away from the sensor 3. This separates sensor 3 from lifting sleeve 2, reducing the impact of base 1 vibration on sensor 3 sampling. Sensor 3 samples the measured part 11. After sampling, lifting sleeve 2 moves closer to sensor 3, de-energizing electromagnet 4, causing it to detach from the measured part 11. Simultaneously, detachment electromagnet 5 is energized, causing sensor 3 to move closer to lifting sleeve 2 and into the second section 22. When in-place sensor 10 detects a signal and the sheet metal resets, sensor 3 is fully returned to its original position. Finally, lifting sleeve 2 moves away from the measured part 11, and sensor 3 resets with lifting sleeve 2. The reset state of spring 9 drives conductive sheet 8 to reset, completing the sampling process. Therefore, the flexible lifting mechanism of the adsorption sensor 3 moves the sensor 3 by lifting the sleeve 2, so that the sensor 3 is close to the test piece 11, and then adsorbs onto the test piece 11 by the adsorption electromagnet 4. This reduces the distance when the adsorption electromagnet 4 is adsorbed onto the test piece 11, thereby reducing the impact on the sensor 3 caused by the excessively fast movement speed, reducing the correction time of the sensor 3, and thus enabling the sensor 3 to better sample the test piece 11, improving the sampling efficiency.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
