Description

Technical Field

[0001] The utility model belongs to the field of coal mine safety production, and in particular relates to a device for fixing a gas pump vibration sensor on a motor or a pump body. Background Art

[0002] The vibration sensor takes the original mechanical quantity to be measured as the input quantity of the vibration sensor, which is then received by the mechanical receiving part to form another mechanical quantity suitable for conversion, and finally converted into electrical quantity by the electromechanical conversion part. Therefore, the working performance of a sensor is determined by the working performance of the mechanical receiving part and the electromechanical conversion part.

[0003] The gas pump vibration sensor is fixed on the motor, reducer or pump body of the equipment to monitor the horizontal and vertical vibration values ​​of the equipment in real time. When the vibration value exceeds the set value, the monitoring system will send out an audible and visual alarm. In actual use of the existing technology, the gas pump vibration sensor is adsorbed on the equipment with a magnet, but due to the small suction force of the magnet and the large surface roughness of the fixed equipment, the fixation is not firm, and false alarms are often given, which affects the correct judgment of the operator and maintenance personnel on the fault, and even overturns the machine. Utility Model Content

[0009] The sensor pressing plate is located in the placement area and is arranged parallel to the motor or the pump body. The sensor pressing plate is used to press the gas pump vibration sensor against the motor or the pump body to prevent the gas pump vibration sensor from being separated from the motor or the pump body.

[0010] The spring is located in the placement area and between the sensor pressure plate and the third sensor fixing plate. One end of the spring is fixedly connected to the sensor pressure plate, and the other end of the spring is against the third sensor fixing plate. The spring is used to generate pressure on the sensor pressure plate so that the sensor pressure plate presses the gas pump vibration sensor against the motor or pump body. The spring is also used to cushion the vibration of the sensor pressure plate through its elasticity during the vibration of the motor or pump body.

[0011] Furthermore, it also includes: a protective cover, which is located in the placement area and is a cylindrical structure with openings at both ends. The opening is larger at one end and smaller at the other end. The protective cover is sleeved on the spring and is close to the third sensor fixing plate. The small end of the protective cover is fixedly connected to the third sensor fixing plate and is coaxially arranged with the lead-out hole. The large end of the protective cover is arranged toward the sensor pressure plate. The protective cover is used to protect the spring.

[0012] Furthermore, a through hole is opened on the sensor pressure plate, through which the wire of the gas pump vibration sensor passes, and then passes through the inner cavity of the spring, the large end of the protective cover, the small end of the protective cover and the lead-out hole of the third sensor fixing plate in sequence, and is connected to the external detection device.

[0013] Further, the spring is a conical spring.

[0014] The beneficial effects of the utility model are:

[0016] The utility model fixes the gas pump vibration sensor in the placement area by arranging a sensor pressing plate, so that the gas pump vibration sensor is tightly pressed against the motor or the pump body, thereby ensuring the normal detection of the gas pump vibration sensor and avoiding false alarms;

[0017] The utility model can buffer the vibration amplitude of the sensor pressure plate by arranging a spring, and generate thrust on the sensor pressure plate, so that the sensor pressure plate is pressed against the gas pump vibration sensor;

[0018] The utility model can protect and limit the conical spring by arranging the protective cover, so as to prevent the end of the conical spring from deflecting and twisting. BRIEF DESCRIPTION OF THE DRAWINGS
