Description

Technical Field

[0001] The utility model discloses a rotation speed sensor supporting device, belonging to the technical field of instrument measurement. Background Art

[0002] The speed sensor is a sensor that converts the speed of a rotating object into an electrical output. The speed sensor is an indirect measuring device, usually used to measure the speed of rotating parts such as motors, gearboxes, and drive shafts, and has a profound impact on the fault diagnosis and online monitoring of rotating equipment. Before use, the speed sensor needs to be fixed in a specified position with a bracket so that the speed sensor can measure the speed of the rotating object.

[0003] There will be a pipe clamp on the speed sensor bracket. When in use, the staff needs to fix the speed sensor on the pipe clamp. Currently, the commonly used sensor bracket fixing methods are mainly threaded connection and magnetic connection. For threaded connection, the speed sensor bracket is fixed to the equipment body by threaded connection. However, drilling holes on the equipment body is usually not allowed, and there will be disadvantages such as poor fixing ability and poor installation flexibility. For magnetic connection, the sensor is prone to loosening after long-term use after installation, which may cause problems such as liquid leakage at the connection point between the sensor and the engine. Therefore, it is particularly important to find a new fixing method. Utility Model Content

[0004] The utility model aims to provide a rotation speed sensor support device in order to solve the problems of poor fixing ability, poor installation flexibility, and easy loosening after long-term use in the support device of the traditional rotation speed sensor.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The utility model provides a rotation speed sensor supporting device, comprising a positioning seat and a mounting seat;

[0007] The positioning seat is composed of a vertically fixed horizontal support plate and a vertical support plate, and the horizontal support plate and the vertical support plate of the positioning seat are respectively provided with a horizontal connecting long hole and a vertical connecting long hole; the width of the horizontal connecting long hole on the horizontal support plate matches the width of the speed sensor installation position;

[0008] The bottom of the mounting seat is a rectangular support frame with an opening at the rear end, a hole is opened in the middle of the front side plate surface of the rectangular support frame to connect the locking screw, the upper plate surface of the rectangular support frame is provided with a clamping claw connecting frame, the clamping claw connecting frame is connected to the clamping claw through a tension spring, a clamping portion is extended downward from the rear end of the clamping claw, and a clamping space is formed between the rear side plate surface of the mounting seat and the clamping portion of the clamping claw;

[0009] The front side plate surface of the mounting seat is fixed to the vertical connecting long hole of the vertical supporting plate of the positioning seat by the locking screw, and the speed sensor is fixed to the horizontal connecting long hole of the horizontal supporting plate of the positioning seat by a nut.

[0010] In order to improve the reliability of the installation of the supporting device, the rear side plate surface of the rectangular supporting frame of the mounting seat is a clamping plate connected by a spring, and the clamping plate is made of magnetic material.

[0011] Limiting columns are fixed rearwardly at both ends of the front side plate surface of the mounting seat for limiting the clamping plate forwardly.

[0012] Working process

[0013] When measuring the rotational speed of the bearing device, the clamping claw of the supporting device is clamped on the bearing seat of the bearing device, and the rear side plate surface of the mounting seat and the clamping part of the clamping claw are clamped on the side of the bearing seat of the bearing device through the tension spring; by adjusting the fixing position of the locking screw on the vertical connecting long hole of the vertical support plate and the fixing position of the rotational speed sensor on the horizontal connecting long hole of the horizontal support plate, the measuring direction of the rotational speed sensor is facing the axis of the bearing device.

[0014] Beneficial Effects

[0015] The support device of the utility model is used to support the speed sensor and has the function of adjusting the vertical direction and the horizontal direction. The support device of the utility model uses magnetic attraction and spring elastic force to clamp the bearing device, so that the support device can be firmly fixed on the device and will not loosen when the device vibrates violently. The support device of the utility model can be applied to bearing seats of different widths, which is convenient for adjusting the height and angle of the speed sensor and convenient for the staff to quickly and flexibly fix the sensor to the monitoring position.
