Description

Technical Field

[0001] The utility model relates to the technical field of equipment monitoring, in particular to an installation device of a temperature-vibration integrated sensor. Background Art

[0002] With the development of industrial intelligence, more and more industrial equipment requires online monitoring for precise control and maintenance. The installation of sensors is an essential task.

[0003] One installation method of the existing temperature-vibration integrated sensor is stud installation, which requires drilling holes on the equipment and is suitable for customization of newly purchased equipment by equipment manufacturers; another installation method is magnetic attraction and gluing or either of the two alone. However, in industrial practice, both equipment drilling installation and magnetic attraction and gluing have certain limitations.

[0004] It is inconvenient to drill holes on the existing equipment, and some equipment cannot be drilled. Therefore, most sensor manufacturers use magnetic adsorption and gluing to facilitate installation on existing equipment on site. This method is easy to install, but the magnetic head is easily affected by environmental dust and temperature, and the magnetic attraction performance is weakened and falls off. The direct gluing method has a small contact surface and insufficient strength. It is easy to fall off due to heat and moisture. The greater defect is that both magnetic adsorption and gluing have poor temperature conductivity and inaccurate temperature measurement. The measured temperature is often 10-15 degrees lower than the actual temperature. Utility Model Content

[0005] In order to improve the convenience, firmness and accuracy of temperature measurement between a temperature-vibration integrated sensor and equipment, the utility model provides a mounting device for the temperature-vibration integrated sensor.

[0006] The utility model provides a temperature-vibration integrated sensor installation device that adopts the following technical solution:

[0007] A mounting device for a temperature-vibration integrated sensor comprises a sensor body, a mounting plate and a device, wherein the bottom of the sensor body is overlapped with the top of the mounting plate, the bottom of the mounting plate is fixedly connected to the outer surface of the device, a through hole is opened on the top of the mounting plate, a groove is formed at the bottom of the sensor body, a wire is connected to the inside of the groove, one end of the wire is fixedly connected to a temperature probe, one end of the temperature probe is clamped to the outer surface of the device, the temperature probe is located inside the through hole, and a screw is threadedly connected to the inside of the groove.

[0008] By adopting the above technical solution, the temperature probe connected to the sensor body is fixed to the outer surface of the device through the mounting plate and the screw, so that the sensor body can detect the surface of the device through the temperature probe 4, avoiding relative movement between the temperature probe and the device when the device moves, thereby enhancing the accuracy of temperature measurement.

[0009] Preferably, a spring is fixedly connected to the top of the temperature probe, one end of the spring is fixedly connected to the top of the inner wall of the groove, and the wire is located inside the spring; a through cavity is opened inside the screw, and the interior of the through cavity is sleeved on the outer surface of the temperature probe; the interior of the through cavity is connected to the interior of the groove.

[0010] By adopting the above technical solution, the temperature probe is always in close contact with the surface of the equipment due to the elastic force given by the spring, and the temperature measurement is accurate with an error of no more than 1°.

[0011] Preferably, the outer surface of the screw is sleeved on the inside of the through hole, and the bottom end of the screw is clamped on the outer surface of the device.

[0012] By adopting the above technical solution, after the connection between the screw and the device is locked, it can be prevented that the temperature probe and the device move relative to each other when the device is moved or impacted.

[0013] Preferably, two folded edges are provided at the bottom of the mounting plate, and the connection between the folded edge of the mounting plate and the top is in a 45° groove shape; the two folded edges are symmetrically distributed on both sides of the screw.

[0014] By adopting the above technical solution, the interior of the mounting plate is trapezoidal when viewed from the side, and the symmetrical folded edges are conducive to the mounting plate releasing the pressure of the sensor body to the surface of the equipment. The folded edges of the mounting plate, the surface of the equipment and the top of the mounting plate form a triangular structure, which can enhance the bearing capacity of the mounting plate.

[0015] Preferably, a nut is threadedly connected to the outer surface of the screw rod, one side of the nut is clamped to one side of the mounting plate, and the nut is located inside the mounting plate.

[0016] By adopting the above technical solution, the bottom of the mounting plate overlaps the top of the nut. By adjusting the position of the nut on the bolt, the height of the bolt can be adjusted, and at the same time, the strength of the through hole is enhanced to prevent the through hole from being squeezed and deformed.

[0017] In summary, the utility model has the following beneficial technical effects:

[0018] 1. The device is provided with a mounting plate. Sealant or super glue is applied around the mounting plate C. The folded edge of the mounting plate is large enough to fit the equipment. After curing, the super glue has sufficient strength and rigidity and is not easy to fall off. At the same time, the accuracy of vibration measurement is guaranteed, and the reliability is high. At the same time, the screw is directly inserted into the interior of the sensor body to prevent dust from entering the interior of the screw. The surface of the equipment is always kept clean, and there will be no dust affecting the accuracy of the temperature probe detection. The temperature probe is always close to the clean equipment surface by the elastic force of the spring, and the temperature measurement is accurate, with an error of no more than 1 degree.

[0019] 2. The device is provided with bolts, and the screw is threadedly connected to the bottom of the sensor body. To repair or replace the sensor, you only need to loosen the connecting screw in the opposite direction to separate the sensor body and the mounting plate, and then pull out the temperature probe, which can be directly removed for processing. It is convenient and fast, and the overall installation and replacement are simple, which is conducive to avoiding re-drilling holes on the surface of the equipment or re-magnetizing and gluing to replace the sensor body.
