Description

Technical Field

[0002] Mining displacement sensors are mining equipment that can accurately measure the extension and retraction displacement of components such as pistons. They support convenient sensor replacement, can operate independently, and help mining equipment operate stably and efficiently. A sensor is a detection device that can sense a specified measurand and convert it into a usable signal output according to a certain rule. It is widely used in various industries to realize automatic detection and control.

[0003] In the existing technology, some mining displacement sensors consist of a detection mechanism, a displacement measuring rod, a magnetic ring, a position magnet, a protective structure, a controller, and a power supply equipment. The working principle is based on the magnetostrictive effect. When the position magnet moves with the object being measured, it interacts with the magnetic ring to generate a magnetic field, causing strain in the internal waveguide wire and generating strain pulses. The controller receives the pulse signals, calculates the displacement, and outputs the result, thereby realizing real-time and accurate monitoring of the displacement of mining equipment components and adapting to the complex mining environment.

[0004] In existing technologies, the replacement of some mining displacement sensor detection mechanisms is quite troublesome, making it difficult to adapt to different mine detection methods. It is also difficult to provide independent power to the equipment. The working environment is dusty, making the equipment prone to contamination, and the protective equipment is quite complex. Therefore, a mining displacement sensor is proposed to solve the above problems. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] A displacement sensor for mining, with reference to Figure 1 and Figure 2 The sensor includes a protective shell 1, which serves as the overall support frame for the sensor. A detection mechanism 2 is slidably connected inside the shell, enabling the core function of displacement detection. A protective mechanism 3 is fixedly connected to the outside of the protective shell 1, providing physical protection for the internal components. The detection mechanism 2 includes a piston rod 22, which is slidably connected to the outside of the protective shell 1 and is a key component for displacement transmission. A connector 21 is fixedly connected to the rear end of the piston rod 22, and a piston head 23 is fixedly connected to the front end. The piston head 23 moves synchronously with the piston rod 22. A magnetic ring 24 is placed on the outside of the piston head 23, and the magnetic ring 24 cooperates with a subsequent position magnet 213. The displacement signal is converted. The protective shell 1 has two inlet and outlet components 25 fixedly connected to the outside for the input and output of hydraulic oil, which provides power for the piston movement. Both inlet and outlet components 25 include inlet and outlet 251. The inlet and outlet 251 is fixedly connected to the outside left side of the protective shell 1 and is the passage of hydraulic oil. A rubber ring 252 is placed inside the inlet and outlet 251. A gasket 253 is placed to the left of the rubber ring 252. The two together play a sealing role to prevent hydraulic oil leakage. A retainer 254 is threadedly connected to the outside of the inlet and outlet 251 to press the sealing components. An inlet and outlet pipe 255 is placed inside the rubber ring 252 to realize the connection between hydraulic oil and external oil circuit. Specifically, the external hydraulic system supplies and extracts hydraulic oil into the protective shell 1 through the inlet / outlet pipes 255 and inlet / outlet 251 of the inlet / outlet component 25. The rubber ring 252 and gasket 253 ensure that the oil circuit is sealed and leak-free. The hydraulic oil pushes the piston head 23 of the detection mechanism 2, causing the piston rod 22 to slide inside the protective shell 1. The connector 21 moves synchronously with the piston rod 22, converting the external displacement into the linear motion of the piston assembly. When the piston head 23 moves, its external magnetic ring 24 and the subsequent position magnet 213 produce a relative position change, converting the mechanical displacement into an electrical signal to complete the detection. Throughout the process, the protective shell 1 provides support, and the external protection mechanism 3 isolates the interference from underground dust, impacts, etc., ensuring the stable operation of the component.

[0013] Reference Figure 3 , Figure 5 and Figure 6The protective shell 1 has a threaded connection to a protective shell 26, which protects the internal detection element. A lever 27 is rotatably connected to the front end of the protective shell 26, and a spring 28 is fixedly connected to the rear end of the lever 27. Under the elastic action of the spring 28, the lever 27 can initially fix the detector 29. A measuring rod 211 is slidably connected inside the protective shell 26, and the detector 29 is fixedly connected to the front end of the measuring rod 211. The detector 29 is used to receive and process displacement signals. A fixing block 210 is fixedly connected to the front end of the protective shell 26. By pressing and rotating the detector 29 inward, the groove of the detector 29 disengages from the fixing block 210, thereby removing the measuring rod 211 for sensor replacement. A magnetic shielding pad 212 is slidably connected to the outside of the housing 26 to provide magnetic shielding and prevent magnetic field interference. A position magnet 213 is slidably connected to the outside of the protective housing 26. The position magnet 213 interacts with the magnetic ring 24 placed outside the piston head 23. When the magnetic ring 24 moves with the piston head 23, the change in magnetic field will induce strain pulses inside the sensor. A screw 214 is threadedly connected to the inside of the magnetic shielding pad 212 to fix the magnetic shielding pad 212 and the position magnet 213. A battery 215 is threadedly connected to the front end of the protective housing 26 to provide power to the detector 29 and facilitate replacement. A controller 216 is fixedly connected to the outside of the battery 215 to control the power supply and signal processing of the battery 215.

[0014] Specifically, the protective shell 26 is threaded into the protective shell 1 to provide protection for the detection element. The battery 215 provides power, and the controller 216 regulates the power supply and signal processing. The magnetic ring 24 moves with the piston head 23 and generates a magnetic field change with the position magnet 213. The magnetic isolation pad 212 isolates interference. The magnetic field change is received and processed by the detector 29. The lever 27 fixes the detector 29 under the action of the spring 28. When replacing, the detector 29 is rotated to disengage its groove from the fixing block 210, and the measuring rod 211 can be pulled out. The screw 214 fixes the magnetic isolation pad 212 and the position magnet 213 to ensure magnetic field stability and ensure accurate conversion and transmission of displacement signals.

[0015] Reference Figure 1 , Figure 2 and Figure 4The protective mechanism 3 includes a fixing plate 31, which is externally fixed to the left side of the protective shell 1, serving as the mounting base for the protective mechanism 3. A rotating shaft 32 is rotatably connected to the rear side of the fixing plate 31. A spring 33 is externally fixed to the rotating shaft 32. A connecting block 34 is externally fixed to the front side of the spring 33. A rotating shaft 35 is internally rotatably connected to the connecting block 34, facilitating the rotation of the flip cover 36. The flip cover 36 is externally fixed to the right side of the connecting block 34. The spring 33 provides tension for opening the flip cover 36. The deformation of the spring 33 pulls the connecting block 34 to rotate along the rotating shaft 35, thus providing tension for opening the flip cover 36. The flip cover 36 can shield and protect the internal components of the protective shell 1, reducing the impact of the external environment on the internal equipment. To prevent damage, a buckle 37 is fixedly connected to the outer right side of the flip cover 36, and a sliding rod 38 is slidably connected to the inner front end of the protective shell 1. A spring 39 is fixedly connected to the outer left side of the sliding rod 38, and a locking block 310 is fixedly connected to the outer left side of the spring 39. By pressing the sliding rod 38, a spring 4 311 is fixedly connected to the outer middle of the locking block 310, which causes the spring 39 and the spring 4 311 to deform together, thereby pushing the locking block 310 and disengaging it from the buckle 37, thus locking the flip cover 36. The spring 39 and the spring 4 311 work together to keep the locking block 310 in a stable locked state, thereby quickly closing the equipment opening and reducing the entry of contaminants. A handle 312 is fixedly connected to the outer right side of the protective shell 1 to facilitate the handling and installation of the sensor. Specifically, the fixed plate 31 provides an installation base for the protective mechanism 3. The flip cover 36 is connected to the connecting block 34 through the rotating shaft 2 35. Under normal conditions, the springs 39 and 4 311 cause the locking block 310 to engage with the buckle 37, and the flip cover 36 locks and blocks the internal components of the protective shell 1. When it needs to be opened, press the sliding rod 38 to push the locking block 310 to deform the springs 39 and 4 311. The locking block 310 disengages from the buckle 37, and the deformation of the spring 2 33 pulls the connecting block 34 to rotate along the rotating shaft 1 32, thereby opening the flip cover 36. The handle 312 facilitates the handling and installation of the sensor. The whole system achieves a balance between protection and convenient opening and closing.

[0016] The implementation principle of this application embodiment is as follows: First, the protective shell 26 of the detection mechanism 2 is threaded into the piston rod 22. The magnetic shielding pad 212 and screw 214 are placed into the piston head 23 in sequence. The magnetic shielding pad 212 and the position magnet 213 are fixed by multiple screws 214. The magnetic ring 24 is placed outside the piston head 23. The detector 29 is pressed inward and rotated. The groove of the detector 29 is disengaged from the fixing block 210, thereby removing the measuring rod 211 and replacing the sensor. The replaced sensor is slid into the protective shell 26 and pressed inward and rotated in the opposite direction, so that the groove of the detector 29 is stuck in the fixing block 210. The lever 27 is stuck in the outer middle of the detector 29 under the action of the spring 28, thereby completing the replacement. Pressing the sliding rod 38 releases the latch 310 from the buckle 37 under the elastic action of springs 39 and 311. Spring 2 is in an extended state. Under the pull of spring 2, the connecting block 34 is pulled to rotate along the rotating shaft 35, thereby pulling the flip cover 36 open and allowing the internal equipment to be replaced. Under the action of the inlet / outlet assembly 25, hydraulic oil enters the equipment. The piston's operation is controlled by controlling the amount of oil entering the front and rear spaces. The controller 216 controls the battery 215 to power the detector 29, enabling the equipment to operate independently. Under the action of the position magnet 213 and the magnetic ring 24, the extension and retraction of the piston are accurately measured.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
