Description

Technical Field

[0001] The utility model relates to the technical field of vibration monitoring, in particular to a vibration monitoring device for a relay pump station. Background Art

[0002] During the composite slurry shield and excavation process, due to the complex excavation strata, large-diameter stones are easily stuck in the pump impeller during the slurry discharge process. If foreign objects are stuck in the impeller during the excavation process and are not discovered and dealt with in time, abnormal damage to the pump station will be caused.

[0003] When foreign matter gets stuck in the impeller, the impeller rotation will not reach dynamic balance, causing the relay pump station to vibrate abnormally at a high frequency. The vibration at the bearing assembly is most obvious. The vibration sensor on the bearing assembly of the relay pump can detect the frequency and promptly detect the foreign matter stuck in the impeller. However, the vibration sensor is adsorbed on the bearing assembly of the relay pump through a magnetic base. The vibration sensor is prone to movement or falling off during use, which reduces the accuracy and stability of the sensor monitoring. Utility Model Content

[0023] Furthermore, a protective mechanism is provided on the surface of the base 2, and the protective mechanism includes a base frame 3, the base frame 3 is snap-connected to the surface of the base 2, spring sheets 31 are fixedly connected on both sides of the base frame 3, a protective tube 32 is fixedly connected to the surface of the base frame 3, a rubber ring 33 is fixedly connected to the surface of the protective tube 32, and a fixing rod 34 is fixedly connected to the surface of the base 2. The service life of the vibration sensor 11 will be reduced after being affected by moisture and dust, and the protective mechanism can protect the vibration sensor 11, reduce the degree of moisture and dust on the vibration sensor 11, and extend the service life of the vibration sensor 11.

[0024] Furthermore, a circular hole is opened on the surface of the base 2, and the magnetic base 21 is adsorbed on the surface of the relay pump body 1 through the circular hole. The diameter of the circular hole of the base 2 is the same as the diameter of the magnetic base 21. The base 2 limits the position of the magnetic base 21 on the relay pump body 1 through the circular hole, thereby limiting the position of the vibration sensor 11 on the relay pump body 1, avoiding the vibration sensor 11 from being offset on the relay pump body 1.

[0025] Furthermore, guide holes are opened on both sides of the base 2, and the limit rod 24 slides on the guide hole of the base 2. The circular hole of the base 2 is connected to the guide hole of the base 2. Two groups of limit rods 24 are respectively arranged on both sides of the base 2. Two groups of reset springs 22 and limit rods 24 are fixedly connected to one group of connecting plates 23 at the same time. The limit rod 24 slides on the guide hole of the base 2 to the circular hole of the base 2.

[0026] Furthermore, the elastic force of the reset spring 22 acts on the limit rod 24 through the connecting plate 23. The limit rod 24 is in contact with the magnetic seat 21 on the circular hole of the base 2. The limit rod 24 limits the magnetic seat 21 on the surface of the relay pump body 1, thereby realizing the installation of the vibration sensor 11 on the relay pump body 1 and avoiding the vibration sensor 11 from falling off after the relay pump body 1 is installed.

[0027] Furthermore, a slot is provided on the surface of the base 2, and the base frame 3 is snap-connected to the slot of the base 2. The base frame 3 limits the position of the protective tube 32 on the base 2. The bottom of the protective tube 32 is open, and the base frame 3 is in the shape of a "mouth". The fixing rod 34 is fixedly connected to the slot of the base 2. The fixing rod 34 limits the position of the base frame 3 in the slot of the base 2 through the spring sheet 31.

[0028] Furthermore, the spring sheet 31 is in an "L" shape. The spring sheet 31 contacts the connecting fixing rod 34 on the slot of the base 2. The fixing rod 34 limits the upward movement of the spring sheet 31. The rubber ring 33 slides on the surface of the connecting line 12. The protective tube 32 slides on the surface of the connecting line 12 through the rubber ring 33. The rubber ring 33 reduces the friction on the connecting line 12 and ensures the sealing of the top of the protective tube 32. The protective tube 32 is sleeved on the outside of the vibration sensor 11 during the sliding process to protect the vibration sensor 11.

[0029] Working principle: weld the base 2 to the surface of the relay pump body 1, and magnetically absorb the magnetic base 21 from the circular hole of the base 2 to the surface of the relay pump body 1. The elastic force of the reset spring 22 acts on the limit rod 24 through the connecting plate 23. The limit rod 24 limits the position of the magnetic base 21 on the circular hole of the base 2. The base 2 and the limit rod 24 limit the position of the magnetic base 21 on the surface of the relay pump body 1, thereby preventing the magnetic base 21 from moving and falling off, and further preventing the vibration sensor 11 from moving and falling off on the relay pump body 1.

[0030] The spring sheets 31 on both sides of the base frame 3 are pressed to engage the base frame 3 with the slot of the base 2. At this time, the spring sheets 31 are released. The spring sheets 31 contact the fixing rods 34 on the slot of the base 2 under the action of elastic force. The fixing rods 34 limit the position of the base frame 3 on the base 2 through the spring sheets 31. The protective tube 32 slides on the surface of the connecting line 12 through the rubber ring 33. When the base frame 3 is fixed on the base 2, the protective tube 32 slides through the rubber ring 33 to be sleeved on the outside of the vibration sensor 11. The protective tube 32 on the surface of the base 2 prevents the vibration sensor 11 from getting damp and dusty, thereby improving the service life of the vibration sensor 11.
