[0002] Shield construction is a commonly used construction method in modern urban underground projects, especially in urban subway construction. During the shield construction process, when the shield machine passes through the underground continuous wall, vibrations will be generated. These vibrations will affect the surrounding environment and structural safety. Therefore, it is very necessary to monitor the vibration of the underground continuous wall. It helps to evaluate the potential impact of construction activities on adjacent buildings and the environment, and take corresponding prevention and control measures.

[0003] In the prior art, during the use of traditional wall vibration monitoring devices, when the adjustment part slides along the resistor sheet, the change in contact area will cause a change in the resistance value in the circuit. However, due to its relatively fixed structure, when replacing different walls, it is impossible to effectively adjust the resistance threshold to trigger an alarm, which reduces the adaptability of the wall vibration monitoring device and thus affects its use effect. Although the existing wall vibration monitoring device can effectively adjust the resistance threshold, after long-term use, since the adjustment component is installed between the bearing and the support column, if lubrication is not added in time, the adjustment component cannot be effectively rotated during the vibration monitoring process, and the operator cannot control the application of the lubricant when manually applying it, resulting in poor coating effect, thereby reducing the monitoring accuracy and affecting the use effect of the wall vibration monitoring device.

[0047] First, pull the plug rod 11 forward to drive the push block 14 at its rear side to move forward. At this time, the elastic force of the reset member 31 is used to push the two limit plates 30 to slide upward along the inner wall of the slide groove 29 when one side of the push block 14 is separated from the top of the plug block 15, thereby driving the bottom of the plug block 15 to separate from the installation groove 36. Then, pull the installation column 5 forward to drive the connecting column 7 to separate from the inner wall of the bearing 8. At this time, since the separated sides of the two extrusion rods 32 are both in contact with the inner wall of the bearing 8, When the connecting column 7 gradually separates from the inner wall of the bearing 8, the elastic force of the reset member 28 is used to drive the two mounting blocks 27 to move backwards, and the front end of the mounting block 27 is clamped on the inner wall of the clamping groove 37, thereby driving the two pistons 20 to move backwards. At this time, the piston 20 will separate from the middle of the oil outlet groove 19, allowing it to be in a flowing state. At this time, a small amount of lubricant will be stored in the storage tank 10, allowing the lubricant to flow through the oil outlet groove 19 to the surface of the sponge block 18, and the sponge block 18 will absorb When the two extrusion rods 32 move toward each other, they will push the installation block 27 to drive the piston 20 to block the oil outlet groove 19 and squeeze the reset piece 28 at the same time.

[0048] Embodiment 3: On the basis of embodiment 2, in order to facilitate the adjustment of the position of the mounting column 5 so as to absorb the remaining lubricant on the surface of the bearing 8, a sponge block 21 is installed on the front side of the mounting column 5, and two card slots 25 are provided at the rear end of the plug-in rod 11. A card head 26 is inserted into the inner wall of the card slot 25. The card heads 26 on the left and right sides are both installed on the front end of the push block 14, and two fitting blocks 9 are installed on the front side of the mounting column 5.

[0049] When the monitoring device is not needed, first pull the plug rod 11, and drive the movable plate 24 at the bottom thereof to move forward, and squeeze the adsorption sponge 12, and squeeze the adsorbed lubricant to the inner wall of the collecting tank 13, then move the mounting column 5 and the connecting column 7 forward to remove them, and then pull the connecting column 7 backward to separate them from the push block 14, at this time pull the push block 14 to separate the two clamping heads 26 at the front end thereof from the clamping groove 25, and separate the front side of the mounting block 27 from the clamping groove 37, after the disassembly is completed, turn the mounting column 5, at this time separate the front end of the plug rod 11 from the push block 14, Use the clamping head 26 to install it, remove the two fitting blocks 9 at the same time, then reset the installation column 5 and the connecting column 7 after the position is reversed, and install them between the two fitting blocks 9 and the clamping groove 37, clamp the position of the piston 20 to keep it in a blocked state, and at the same time, the front ends of the two installation blocks 27 will be plugged into the positions where the original fitting blocks 9 are installed. At this time, the position adjustment of the installation column 5 is completed, and then the sponge block 21 is used to absorb the lubricant remaining on the surface of the bearing 8, so that the collected lubricant can be stored on the inner wall of the collection tank 13, which is convenient for subsequent use and reduces the cost of use.

[0050] Embodiment 4: On the basis of embodiment 3, in order to conveniently squeeze out the lubricant adsorbed by sponge block 18 and sponge block 21 and let it drip onto the inner wall of the collecting tank 13, the inner bottom of the mounting column 5 is provided with a collecting tank 13, a push rod 23 is plugged into the rear side of the inner wall of the plug-in rod 11, a spring 22 is installed at the front end of the push rod 23, a moving plate 24 is installed at the bottom front side of the push rod 23, an adsorption sponge 12 is arranged at the bottom front side of the moving plate 24, and a filter plate 17 is installed at the inner wall of the storage tank 10; the front end of the spring 22 is installed at the plug-in rod The front side of the inner wall of 11 is driven by the push rod 23 to drive the movable plate 24 at the bottom thereof to squeeze the adsorption sponge 12, and then the collected lubricant is collected to the inner wall of the collecting tank 13. The movable plate 24 is slidably connected to the bottom of the inner wall of the mounting column 5. The adsorption sponge 12 is arranged at the bottom of the inner wall of the mounting column 5, and the front side of the adsorption sponge 12 is fitted between the sponge block 21, and the rear side is fitted between the sponge block 18, so that the lubricant adsorbed by the sponge blocks 18 and 21 is collected to the inner wall of the collecting tank 13 by using the adsorption sponge 12.

[0051] When the position of the mounting column 5 is adjusted, one side of the adsorption sponge 12 fits against the sponge block 18, and the other side fits against the sponge block 21, and the long-term placement state allows the lubricant to settle downward and be adsorbed by the adsorption sponge 12, and then the push rod 23 is pushed backward and drives the movable plate 24 to slide on the inner bottom of the mounting column 5, while squeezing and pushing the upper part of the adsorption sponge 12, so that the adsorbed lubricant flows to the inner wall of the collecting tank 13. After completion, the push rod 23 is released, and the elastic force of the spring 22 is used to drive the push rod 23 to reset, so as to facilitate subsequent use. At this time, the remaining lubricant will be stored on the inner wall of the collecting tank 13. When it is needed, it will be discharged through the discharge pipe at the bottom thereof, and injected into the interior of the storage tank 10 after being filtered through the filter plate 17, so that it can be recycled, reduce waste, and thus reduce the cost of use.

[0052] Embodiment 5: On the basis of embodiment 4, in order to facilitate fixing the position of the adjusting part 4 after adjustment, a movable groove 35 is opened on the outside of the fixing column 6, and a connecting block 16 is installed on the inner wall of the movable groove 35, and a reset member 33 is installed on the inner wall of the connecting block 16, and a clamping block 34 is installed at the bottom of the reset member 33, and the bottom end of the clamping block 34 passes through the connecting block 16 and is clamped on the inner wall of the movable groove 35, and is installed between the front side of the connecting block 16 and the adjusting part 4.

[0053] When adjusting the position of the adjusting part 4, since the rear side of the adjusting part 4 is installed between the connecting block 16, and the connecting block 16 is installed on the inner wall of the movable groove 35, rotating the adjusting part 4 will drive the connecting block 16 to move along the inner wall of the movable groove 35, and the inner wall of the connecting block 16 is installed with a reset member 33, and the bottom end of the clamping block 34 is inserted into the inner wall of the movable groove 35, so that in the process of rotating the adjusting part 4 to drive the connecting block 16 to move, the elastic force of the reset member 33 is used to push the clamping block 34 to clamp on the inner wall of the movable groove 35, and then after the adjusting part 4 is adjusted, it is convenient to fix the adjusted position, thereby improving the use effect of the monitoring device.

[0054] Embodiment 6: Based on Embodiment 5, a method for monitoring wall vibration during the penetration of a shield wall grinding cutter head includes a device for monitoring wall vibration during the penetration of a shield wall grinding cutter head. The method includes the following steps:

[0055] When in use, the bearing 8 lacks lubricity, which affects the smoothness of the rotation of the adjustment part 4. At this time, the plug-in rod 11 is used to drive the left and right mounting blocks 27 to separate the mounting column 5 from the connecting column 7. At this time, the lubricant passes through the oil outlet groove 19 and is absorbed by the sponge block 18 by the cooperation between the mounting block 27 and the reset member 28. At the same time, the plug-in rod 11, the push block 14 and the plug-in block 15 are used to realize the disassembly and assembly of the connecting column 7 and the mounting column 5.

[0056] When not in use, the mounting column 5 is disassembled by using the plug-in rod 11, and the mounting column 5 is assembled with the clamping head 26 and the mounting block 27. After adjusting the mounting column 5, the mounting column 5 is assembled and adjusted by using the cooperation between the clamping head 26, the mounting block 27, the clamping slot 25 and the clamping slot 37.

[0057] When the lubricant needs to be collected, the adsorption sponge 12 is used to precipitate the lubricant inside the sponge block 18 and the sponge block 21, and the lubricant is adsorbed and collected by the adsorption sponge 12, and then the push rod 23 and the moving plate 24 cooperate to achieve the function of adsorbing and collecting the lubricant;

[0058] When the adjusting part 4 is rotated, the connecting block 16 is installed on the inner wall of the movable groove 35. During the movement of the adjusting part 4, the reset member 33 is used to push the clamping block 34 to be inserted into the inner wall of the movable groove 35. The reset member 33, the clamping block 34 and the movable groove 35 cooperate to limit the adjusting part 4.

[0059] The mounting column 5 and the connecting column 7 can be assembled and disassembled according to the use requirements, and the utility model has rich functions and is easy to use.

[0060] In actual use, the plug rod 11 is first pulled forward to drive the push block 14 at the rear side thereof to move forward. At this time, the elastic force of the reset member 2 31 is utilized so that when one side of the push block 14 is separated from the top of the plug block 15, the two limit plates 30 are pushed to slide upward along the inner wall of the slide groove 29, thereby driving the bottom of the plug block 15 to separate from the mounting groove 36. Subsequently, the mounting column 5 is pulled forward to drive the connecting column 7 to separate from the inner wall of the bearing 8. At this time, since the separated sides of the two extrusion rods 32 are both in contact with the bearing 8, when the connecting column 7 gradually separates from the inner wall of the bearing 8, the elastic force of the reset member 28 is used to drive the two mounting blocks 27 to move backwards, and the front end of the mounting block 27 is clamped on the inner wall of the clamping groove 37, thereby driving the two pistons 20 to move backwards. At this time, the piston 20 will separate from the middle of the oil outlet groove 19, so that it is in a flow state. At this time, a small amount of lubricant will be stored in the storage groove 10, so that the lubricant flows through the oil outlet groove 19 to the surface of the sponge block 18, and the sponge block 18 is 8 adsorption, after maintenance is completed, the installation column 5 is reset, and the rear end of the connecting column 7 is driven to be inserted into the inner wall of the installation groove 36. Since the extrusion rod 32 will first contact the inner wall of the bearing 8 and be in a pushing state, when the two extrusion rods 32 move toward each other, they will squeeze the installation block 27 to drive the piston 20 to block the oil outlet groove 19 and squeeze the reset piece 28 at the same time. At this time, the plug-in rod 11 is pushed backward and the push-out block 14 is driven to move backward along the inner wall of the connecting column 7, thereby resisting the plug-in block 15 to move downward and allow its bottom end to be inserted into the inner wall of the installation groove 36, thereby installing the connecting column 7 and the fixing column 6 together, and squeezing the two reset pieces 2 31 at the same time for subsequent disassembly and assembly. Subsequently, the operator rotates the adjustment part 4 to drive the bearing 8, so that the lubricant adsorbed by the sponge block 18 is coated on the front side of the bearing 8, thereby increasing the lubricity of the bearing 8 and improving its lubricity during rotation, and also reducing the situation of too much or too little lubricant, thereby facilitating the use of the operator and improving the efficiency of maintenance;

[0061] When the monitoring device is not needed, first pull the plug rod 11 and drive the movable plate 24 at the bottom thereof to move forward, squeeze and push the adsorption sponge 12, and squeeze the adsorbed lubricant to the inner wall of the collecting tank 13, then move the mounting column 5 and the connecting column 7 forward to remove them, and then pull the connecting column 7 backward to disengage them from the pushing block 14. At this time, pull the pushing block 14 to disengage the two clamping heads 26 at its front end from the clamping groove 25, and disengage the front side of the mounting block 27 from the clamping groove 37. After disassembly, reverse the mounting column 5. At this time, install the clamping head 26 between the front end of the plug rod 11 and the pushing block 14, and remove the two engaging blocks 9 at the same time. Then reset and install the mounting column 5 and the connecting column 7 after the reversed position, and install the two engaging blocks 9 between the clamping groove 37, jam the position of the piston 20, so that it always remains in a blocked state, and at the same time, the front ends of the two mounting blocks 27 will be plugged into the original engaging blocks 9 for installation. The position of the mounting column 5 is adjusted. Then, the sponge block 21 is used to absorb the lubricant remaining on the surface of the bearing 8. Since one side of the adsorption sponge 12 is in contact with the sponge block 18 and the other side is in contact with the sponge block 21, and the long-term placement state allows the lubricant to be deposited downward and adsorbed by the adsorption sponge 12. Then, the push rod 23 is pushed backward and drives the moving plate 24 to slide on the inner bottom of the mounting column 5, while squeezing and pushing the upper part of the adsorption sponge 12 to make the adsorbed lubricant flow to the inner wall of the collecting tank 13. After completion, the push rod 23 is released and the elastic force of the spring 22 is used to drive the push rod 23 to reset, so as to facilitate subsequent use. At this time, the remaining lubricant will be stored on the inner wall of the collecting tank 13. When it is needed, it is discharged through the discharge pipe at the bottom thereof and injected into the interior of the storage tank 10 after being filtered by the filter plate 17, so that it can be recycled, thereby reducing waste and reducing the cost of use.

[0062] When adjusting the position of the adjusting part 4, since the rear side of the adjusting part 4 is installed between the connecting block 16, and the connecting block 16 is installed on the inner wall of the movable groove 35, rotating the adjusting part 4 will drive the connecting block 16 to move along the inner wall of the movable groove 35, and the inner wall of the connecting block 16 is installed with a reset member 33, and the bottom end of the clamping block 34 is inserted into the inner wall of the movable groove 35, so that in the process of rotating the adjusting part 4 to drive the connecting block 16 to move, the elastic force of the reset member 33 is used to push the clamping block 34 to clamp on the inner wall of the movable groove 35, and then after the adjusting part 4 is adjusted, it is convenient to fix the adjusted position, thereby improving the use effect of the monitoring device.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
