Description
Technical Field
[0001] The utility model relates to the field of acoustic emission probes, in particular to a high-temperature acoustic emission probe fixture. Background Art
[0002] Acoustic emission sensor is an important part of the acoustic emission detection system and an important factor affecting the overall performance of the system. Improper design of the acoustic emission sensor may result in a large difference between the received signal and the expected acoustic emission signal, which directly affects the authenticity of the collected data and the data processing results. Acoustic emission monitoring has high sensitivity and can detect the entire process of defect initiation, expansion and fracture. It can continuously monitor and warn the generation and expansion of defects. It has some advantages that other non-destructive testing methods do not have and is used in many industries.
[0003] Acoustic emission testing technology is a non-destructive testing method that uses the elastic wave signal generated by the energy released when solid materials break, deform or change phase to analyze and study material properties. During testing, a stable pre-tightening force must be applied to the probe to make it close to the surface of the workpiece to be tested. However, when testing high-temperature equipment, it is difficult for workers to make the probe close to the surface of the equipment, which affects the overall detection accuracy. After the test is completed, facing the probe in a complex environment, it is difficult for workers to remove it.
[0004] In summary, when the above structure is used to detect high-temperature equipment, it is difficult for the staff to make the probe close to the surface of the equipment, which will affect the overall detection accuracy. After the detection is completed, it is difficult for the staff to remove the probe in a complex environment. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a high-temperature acoustic emission probe clamp to solve the technical problem that when testing high-temperature equipment, it is difficult for workers to make the probe close to the surface of the equipment, thus affecting the overall detection accuracy, and after the detection is completed, it is difficult for workers to remove the probe in a complex environment.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a high-temperature acoustic emission probe clamp, comprising a sleeve, one end of which is connected to a handle, and the other end of which is rotatably connected to a holder, the inner side of the holder is elastically connected to a clamp, and the front end position of the clamp exceeds the front end position of the holder, and the front end of the holder is connected to a magnet.
[0007] By adopting the above technical solution, the holder is placed on the outer wall of the device to be monitored, and the holder is fixed under the action of a magnet. Since the front end of the clamp exceeds the front end of the holder in a normal state, after the holder is adsorbed, the probe at the front end of the clamp is pressed against the outer wall of the device to be tested by the action of a spring, thereby completing the fixation of the probe. At the same time, a handle is connected to one end of the sleeve. After the test is completed, it can be removed under the action of the handle, making it suitable for different test environments, thereby improving the overall practicality of the device.
[0008] The utility model is further configured that the inner wall of the holder is fixedly connected with a spring, and the other end of the spring is detachably connected with a clamp.
[0009] By adopting the above technical solution, when the holder is connected and attached to the high-temperature equipment, the surface of the high-temperature equipment will squeeze the clamp. During this process, the spring itself will be in a compressed state. When the external force on the surface of the equipment to be tested is removed, there will be a forward squeezing thrust through the restoring force of the spring itself, which can press the probe at the front end of the clamp tightly against the surface of the material to be tested, thereby enhancing the firmness of the probe installation.
[0010] The utility model is further configured such that the handle and the sleeve are detachably connected.
[0011] By adopting the above technical solution, the staff can replace the handle according to actual needs and use different handles in different environments, so as to improve the overall practicality of the device.
[0012] The utility model is further configured that a pull ring is provided on one side of the card seat, and a pull rope is provided on the pull ring.
[0013] By adopting the above technical solution, when installing the probe, one end of the pull rope is connected to the pull ring on the holder. After the probe is installed at the specified position of the equipment to be tested under the action of the handle, if the handle is tilted due to rotation, the staff can also disassemble the holder as a whole according to the pull rope, thereby further improving the protection of the holder disassembly.
[0014] The utility model is further configured that a protective cover is installed on the inner wall of the clamp.
[0015] By adopting the above technical solution, the protective cover can prevent the probe from directly contacting the fixture, effectively preventing the fixture from wearing the outer wall of the probe, and improving the protective effect of the outer wall of the probe.
[0016] The utility model is further configured that the pull ring and the clamping seat are threadedly connected.
[0017] By adopting the above technical solution, when facing an area with a narrow entrance, the threaded connection setting makes it easy for the staff to disassemble the pull ring, allowing the card holder to enter stably, further improving the overall practicality of the device.
[0018] The utility model is further configured that an outer wall of one end of the handle is provided with a rough surface.
[0019] By adopting the above technical solution, the rough setting makes it easy to increase the sliding friction between the handle and the staff's hand, thereby preventing the handle from slipping on the staff's hand during the placement process.
[0020] The utility model is further configured that a limiting mechanism is arranged on the inner side of the outer wall of the clamp.
[0021] By adopting the above technical solution, under the action of the limiting mechanism, it is ensured that the clamp can slide in the horizontal direction during the movement of the spring, thereby preventing the clamp from causing the front end probe to tilt during the sliding process.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] The utility model has a holder rotatably arranged at one end of a sleeve, and a clamp is elastically connected inside the holder. When facing the detection of high-temperature equipment, the staff connects the probe with the clamp, and then places the holder on the outer wall of the equipment to be monitored, and fixes the holder under the action of a magnet. Since the front end of the clamp exceeds the front end of the holder in a normal state, after the holder is adsorbed, the probe at the front end of the clamp is pressed against the outer wall of the equipment to be detected under the action of a spring, thereby completing the fixation of the probe. At the same time, a handle is connected to one end of the sleeve. After the detection is completed, it can be removed under the action of the handle, so that it is suitable for different detection environments, thereby improving the overall practicality of the device.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0030] The following describes an embodiment of the utility model based on its overall structure.
[0031] Embodiment 1
[0032] A high temperature acoustic emission probe fixture, such as Figure 1-Figure 4 As shown, it includes a sleeve 1, a handle 2, a clamping mechanism, a limiting mechanism and a detection mechanism. The handle 2 is connected to one end of the sleeve 1, and the other end thereof is rotatably connected to a holder 3. A rough surface is arranged on the outer wall of one end of the handle 2. The rough arrangement is convenient for increasing the sliding friction between the handle 2 and the staff's hand to prevent the handle 2 from slipping on the staff's hand during placement. At the same time, a clamp 4 is elastically connected to the inner side of the holder 3, and the front end position of the clamp 4 exceeds the front end position of the holder 3. At the same time, a magnet 5 is connected to the front end of the holder 3. When in use, the staff clamps the probe to the clamp 4, and then moves the probe to the outer wall of the high-temperature equipment to be detected under the action of the handle 2. Under the action of the magnet 5, the probe is The holder 3 is fixed. Since the front end of the clamp 4 exceeds the front end of the holder 3 in the normal state, after the holder 3 is adsorbed, since a spring is fixedly connected to the inner wall of the holder and the clamp is detachably connected to the other end of the spring, when the holder 3 is connected and attached to the high-temperature equipment, the surface of the high-temperature equipment will squeeze the clamp 4. During this process, the spring 7 itself will be in a compressed state. When the external force on the surface of the equipment to be tested is removed, there will be a forward squeezing thrust through the reset force of the spring 7 itself, which can press the probe at the front end of the clamp 4 to the surface of the material to be tested, thereby enhancing the firmness of the probe installation. After the test is completed, it can be removed under the action of the handle 2, so that it is suitable for different test environments, thereby improving the overall practicality of the device.
[0033] See also Figure 2 and Figure 3 The handle 2 and the sleeve 1 are detachably connected, and the staff can replace the handle 2 according to actual needs and use different handles 2 in different environments, so as to improve the overall practicality of the device. A protective cover is installed on the inner wall of the clamp 4. The protective cover can prevent the probe from directly contacting the clamp 4, effectively preventing the clamp 4 from wearing the outer wall of the probe, and improving the protection effect of the outer wall of the probe.
[0034] See also Figure 2A limiting mechanism is provided on the inner side of the outer wall of the clamp 4 located on the base 3. Under the action of the limiting mechanism, the clamp 4 can slide in a horizontal direction when it is moved by the spring 7, thereby preventing the clamp 4 from causing the front end probe to tilt during the sliding process.
[0035] Embodiment 2
[0036] like Figure 3 A high-temperature acoustic emission probe fixture is shown, and its overall structure is similar to that of the first embodiment, wherein a pull ring 6 is provided on one side of the holder 3, and a pull rope is provided on the pull ring 6. When the probe is installed, one end of the pull rope is connected to the pull ring 6 on the holder 3. After the probe is installed at the designated position of the device to be tested under the action of the handle 2, if the handle 2 is tilted due to rotation, the staff can also disassemble the holder 3 as a whole according to the pull rope, thereby further improving the protection of the disassembly of the holder 3.
[0037] The working principle of the utility model is as follows: when in use, the handle 2 is connected to one end of the sleeve 1, and then the detection probe is connected to the clamp 4 at the front end. When the staff faces the detection of high-temperature equipment, the holder 3 is moved to the outer wall of the high-temperature equipment. Since a magnet 5 is provided at the front end of the holder 3, the holder is adsorbed on the outer wall of the high-temperature equipment under the action of the magnet 5. Under normal conditions, the front end of the clamp 4 exceeds the front end of the holder 3. During the adsorption of the holder 3, the clamp 4 slides inwardly. Since the holder 3 and the clamp 4 are connected by a spring 7, the probe at the front end of the clamp 4 is closely attached to the outer wall of the device to be monitored under the resetting action of the spring 7, thereby completing the fixing of the probe. After the detection is completed, it is removed under the action of the handle 2, so that it is suitable for different detection environments, thereby improving the overall practicality of the device.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
