Description

Technical Field

[0001] This utility model relates to the field of blasting vibration meter technology, specifically a blasting vibration meter sensor anti-detachment device. Background Technology

[0002] A blasting vibration meter is a specialized device used to monitor and analyze vibration signals generated during blasting operations. Its core function is to record parameters such as the amplitude, waveform, and frequency of blasting vibrations, thereby assessing the impact of blasting on the surrounding environment (such as buildings, rock masses, underground pipelines, etc.) and providing data support for the safety and optimization of blasting construction.

[0003] Based on the above, the following problems were found: Current blasting vibration meter sensors mainly use plaster to directly bond the sensor to the surface of the test point. However, the sensor itself is small in size, has a small adhesion area at the bottom, and usually has a smooth surface, which makes it easy for it to loosen and fall off during use, making it inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a sensor anti-detachment device for blasting vibration meter in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a sensor anti-detachment device for a blasting vibration meter to solve the problems mentioned in the background art.

[0006] A sensor anti-detachment device for a blasting vibration meter includes a fixing plate assembly. A sensor assembly is located at the top center of the fixing plate assembly, and a mounting frame assembly is located on the outside of the sensor assembly. The mounting frame assembly is fixedly connected to the fixing plate assembly. The fixing plate assembly includes a base plate, and a positioning frame is fixedly installed at the top center of the base plate. The positioning frame is located on the bottom outside of the sensor assembly. Several grooves are formed on the bottom of the base plate. The grooves are in the shape of a truncated pyramid and are arranged in a rectangular array. A connecting groove is formed on the outside of the grooves, connecting adjacent grooves. Anchor holes are formed at all four corners of the base plate.

[0007] By adopting the above technical solution, the sensor assembly is designed to easily support the core sensor of the blasting vibration meter, responsible for capturing vibration signals. The mounting bracket assembly and the fixing plate assembly are fixedly connected, facilitating stable fixation of the sensor assembly. The positioning frame facilitates precise positioning of the sensor assembly, improving its installation stability and accuracy. The groove design increases the contact area between the base plate and the plaster, utilizing mechanical interlocking to enhance adhesion and prevent the fixing plate assembly from detaching from its mounting position during use. The truncated pyramid shape, narrower at the top and wider at the bottom, contributes to this design. The design facilitates the flow of gypsum liquid into the grooves during construction. When the gypsum is compressed during solidification, the inclined structure inside the grooves forms "anchor points," significantly improving the bonding strength. The rectangular array of grooves ensures even distribution on the base plate surface. Multi-point contact enhances the overall installation stability. The connecting grooves facilitate smooth flow of gypsum liquid, ensuring it fully fills all grooves and preventing voids. The anchor holes allow for the insertion of anchors to provide mechanical fixation when the surface at the installation location is loose.

[0008] Furthermore, an overflow hole is provided on the outer side of the positioning frame, and the overflow hole is located in the middle of the groove.

[0009] By adopting the above technical solution, the overflow hole allows some plaster liquid to overflow to the top of the base plate when fixing the fixing plate assembly with plaster. After the plaster liquid solidifies, it can further improve the stability of fixing the fixing plate assembly and prevent loosening.

[0010] Furthermore, fixed handles are fixedly installed at both ends of the top of the base plate, and a bubble level is fixedly installed on one side of the middle of the top of the base plate.

[0011] By adopting the above technical solution, the fixed handle and bubble level make it easy to move the fixed plate assembly to the installation position. It also makes it easy to apply pressure to the fixed plate assembly so that the plaster liquid can fill the groove and overflow to the top of the overflow hole. The bubble level makes it easy to ensure that the base plate is installed horizontally when using plaster to fix the fixed plate assembly, which helps to improve the monitoring accuracy of the sensor assembly.

[0012] Furthermore, a positioning groove is provided on the top of the positioning frame, and a screw hole is fixedly provided in the middle of the positioning groove.

[0013] By adopting the above technical solution, the positioning groove and screw hole facilitate the fixed connection between the mounting bracket assembly and the fixing plate assembly, and enable the mounting bracket assembly to securely fix the sensor assembly on the top of the fixing plate assembly.

[0014] Furthermore, the mounting bracket assembly includes a fixing bracket disposed on top of the sensor assembly.

[0015] By adopting the above technical solution and setting up the fixing frame, it is convenient to limit and fix the top of the sensor assembly.

[0016] Furthermore, the fixing frame has an "X" shaped structure, and a handle is fixedly installed at the top center of the fixing frame.

[0017] By adopting the above technical solution, the handle facilitates the movement of the mounting bracket assembly, allowing it to be easily fitted onto the outside of the sensor assembly, thus fixing the sensor assembly to the top of the fixed plate assembly.

[0018] Furthermore, fixing strips are fixedly installed at the bottom of both ends of the fixing frame, and the fixing strips are set at both ends of the sensor assembly.

[0019] By adopting the above technical solution, the setting of the fixing strip facilitates the limiting and fixing of the outer ends of the sensor assembly, and also facilitates the fixed connection between the mounting bracket assembly and the fixing plate assembly.

[0020] Furthermore, a positioning block is fixedly installed at the bottom end of the fixing strip, and the positioning block is set inside the positioning groove.

[0021] By adopting the above technical solution, the positioning block is designed to facilitate quick positioning of the mounting bracket assembly in conjunction with the positioning slot, thus enabling the mounting bracket assembly to securely fix the sensor assembly inside the positioning frame.

[0022] Furthermore, a through hole is provided in the middle of the positioning block, and a fixing screw is inserted inside the through hole, and the fixing screw is threadedly connected to the screw hole.

[0023] By adopting the above technical solution and setting the fixing screws, it is easy to lock the sensor assembly to the base plate, preventing the sensor assembly from shifting or falling off due to explosion vibration.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The sensor assembly facilitates the mounting of the core sensor of the blasting vibration meter, responsible for capturing vibration signals. The mounting bracket assembly and the fixing plate assembly provide a secure connection, ensuring stable fixation of the sensor assembly. The positioning frame facilitates precise positioning of the sensor assembly, improving its installation stability and accuracy. The groove design increases the contact area between the base plate and the plaster, enhancing adhesion through mechanical interlocking and preventing the fixing plate assembly from detaching from its mounting position during use. The truncated pyramidal structure, narrow at the top and wide at the bottom, allows plaster liquid to flow into the groove during construction, preventing the plaster from solidifying during the process. When subjected to pressure, the inclined structure inside the groove forms "anchor points," significantly improving the bonding strength. The rectangular array of grooves facilitates their uniform distribution on the base plate surface. Multi-point contact enhances the overall installation stability. The connecting grooves facilitate the connection of the grooves, allowing for smooth flow of plaster liquid and ensuring that all grooves are fully filled, preventing voids. The anchor holes allow for the insertion of anchors to provide mechanical fixing force when the surface at the installation location is loose. This invention improves the stability and firmness of plaster-fixed sensor assembly installation, effectively preventing loosening and detachment during use, and has high practical value.

[0031] 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.

[0032] Please see Figures 1-5 This utility model provides a technical solution: a sensor anti-detachment device for a blasting vibration meter, comprising a fixing plate assembly 1, a sensor assembly 3 at the top center of the fixing plate assembly 1, which facilitates the support of the core sensor of the blasting vibration meter, responsible for capturing vibration signals; a mounting bracket assembly 2 on the outside of the sensor assembly 3, which is fixedly connected to the fixing plate assembly 1, thus facilitating the stable fixation of the sensor assembly 3; the fixing plate assembly 1 includes a base plate 11, a positioning frame 13 fixedly installed at the top center of the base plate 11, which facilitates the positioning of the sensor assembly 3, improving the installation stability and accuracy of the sensor assembly 3; the positioning frame 13 is located on the bottom outer side of the sensor assembly 3; and several grooves 19 are formed at the bottom of the base plate 11, each groove having a truncated pyramidal structure, which increases the contact area between the base plate 11 and the plaster. The mechanical interlocking action enhances the bonding force and prevents the fixing plate assembly 1 from detaching from the installation position during use. The truncated pyramidal structure, narrow at the top and wide at the bottom, facilitates the flow of gypsum liquid into the groove 19 during construction. When the gypsum is compressed during solidification, the inclined structure inside the groove 19 forms "anchor points," significantly improving the bonding strength. The grooves 19 are arranged in a rectangular array, which facilitates the uniform distribution of the grooves 19 on the surface of the base plate 11. The multi-point contact improves the overall installation stability. A connecting groove 110 is provided on the outer side of the groove 19, connecting adjacent grooves 19. The connecting groove 110 facilitates the connection of the grooves 19, allowing the gypsum liquid to flow smoothly and fully fill all the grooves 19, avoiding hollow defects. Anchor holes 18 are provided at the four corners of the base plate 11. The anchor holes 18 facilitate the insertion of fixing anchors when the surface of the device installation position is loose, providing mechanical fixing force to fix the device.

[0033] The positioning frame 13 has an overflow hole 17 on its outer side. The overflow hole 17 is located in the middle of the groove 19. The overflow hole 17 allows some plaster liquid to overflow from the overflow hole 17 to the top of the base plate 11 when the fixing plate assembly 1 is fixed with plaster. After the plaster liquid solidifies, it can further improve the stability of fixing the fixing plate assembly 1 and prevent loosening.

[0034] The base plate 11 has fixed handles 12 at both ends of its top, and a bubble level 16 is fixedly installed on one side of the top center of the base plate 11. The fixed handles 12 and the bubble level 16 facilitate the movement of the fixed plate assembly 1 to the installation position. They also facilitate the application of pressure to the fixed plate assembly 1 so that the plaster liquid can fill the groove 19 and overflow to the top of the overflow hole 17. The bubble level 16 ensures that the base plate 11 is kept level when the fixed plate assembly 1 is fixed with plaster, which helps to improve the monitoring accuracy of the sensor assembly 3.

[0035] The positioning frame 13 has a positioning groove 14 at the top and a screw hole 15 in the middle of the positioning groove 14. The positioning groove 14 and the screw hole 15 facilitate the fixed connection between the mounting bracket assembly 2 and the fixing plate assembly 1, so that the mounting bracket assembly 2 can securely fix the sensor assembly 3 on the top of the fixing plate assembly 1.

[0036] The mounting bracket assembly 2 includes a fixing bracket 21, which is set on the top of the sensor assembly 3. The fixing bracket 21 facilitates the limiting and fixing of the top of the sensor assembly 3.

[0037] The fixing frame 21 has an "X" shaped structure, and a handle 22 is fixedly installed at the top center of the fixing frame 21. The handle 22 makes it easy to move the mounting frame assembly 2, so that the mounting frame assembly 2 can be sleeved on the outside of the sensor assembly 3, thereby fixing the sensor assembly 3 on the top of the fixing plate assembly 1.

[0038] Among them, fixing strips 23 are fixedly installed at the bottom of both ends of the fixing frame 21. The fixing strips 23 are set at both ends of the sensor assembly 3. The fixing strips 23 facilitate the limiting and fixing of the outer sides of both ends of the sensor assembly 3, and facilitate the fixed connection between the mounting frame assembly 2 and the fixing plate assembly 1.

[0039] The bottom end of the fixing strip 23 is fixedly installed with a positioning block 24. The positioning block 24 is set inside the positioning groove 14. The positioning block 24 is set to facilitate the positioning block 24 to cooperate with the positioning groove 14 to quickly position the installation position of the mounting bracket assembly 2, so that the mounting bracket assembly 2 can stably fix the sensor assembly 3 inside the positioning frame 13.

[0040] The positioning block 24 has a through hole 25 in the middle, and a fixing screw 26 is inserted inside the through hole 25. The fixing screw 26 is threadedly connected to the screw hole 15. The fixing screw 26 can lock the sensor assembly 3 to the base plate 11, preventing the sensor assembly 3 from shifting or falling off due to explosion vibration.

[0041] Specifically, the working principle of this anti-detachment device for the blasting vibration meter sensor is as follows: During use, the fixed handle 12 and the bubble level 16 facilitate the movement of the fixed plate assembly 1 to the installation position. This also allows pressure to be applied to the fixed plate assembly 1, ensuring the plaster liquid fills the groove 19 and overflows to the top of the overflow hole 17. The bubble level 16 ensures the base plate 11 remains level when fixing the fixed plate assembly 1 with plaster, improving the monitoring accuracy of the sensor assembly 3. The groove 19 increases the contact area between the base plate 11 and the plaster, enhancing adhesion through mechanical interlocking and preventing detachment. To prevent the fixed plate assembly 1 from detaching from its installation position during use, the truncated pyramidal structure, narrow at the top and wide at the bottom, facilitates the flow of gypsum liquid into the grooves 19 during construction. When the gypsum is compressed during solidification, the inclined structure inside the grooves 19 forms "anchor points," significantly improving the bonding strength. The rectangular array arrangement of the grooves 19 ensures even distribution on the surface of the base plate 11, and the multi-point contact improves the overall installation stability. The connecting grooves 110 facilitate the connection of the grooves 19, ensuring smooth flow of gypsum liquid and allowing it to fully fill all the grooves 19, avoiding voids. The anchor holes 18 facilitate the installation of the device. When the surface is loose, insert anchor pins to provide mechanical fixing force to secure the device. The overflow hole 17 allows some plaster liquid to overflow to the top of the base plate 11 when fixing the fixing plate assembly 1 with plaster. After the plaster liquid solidifies, it further improves the stability of fixing the fixing plate assembly 1, preventing loosening. The positioning frame 13 facilitates positioning of the sensor assembly 3, improving the installation stability and accuracy of the sensor assembly 3. The handle 22 facilitates moving the mounting bracket assembly 2, making it easy to fit the mounting bracket assembly 2 onto the sensor assembly 3. On the outside, the sensor assembly 3 is fixedly installed on the top of the fixing plate assembly 1. The fixing strip 23 is used to limit and fix the outer ends of the sensor assembly 3, and to facilitate the fixed connection between the mounting bracket assembly 2 and the fixing plate assembly 1. The positioning block 24 is used to quickly position the mounting bracket assembly 2 in conjunction with the positioning groove 14, so that the mounting bracket assembly 2 can firmly fix the sensor assembly 3 inside the positioning frame 13. The fixing screw 26 is used to lock the sensor assembly 3 to the base plate 11, preventing the sensor assembly 3 from shifting or falling off due to explosion vibration.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
