[0044] Example:

[0045] like Figure 1-Figure 4 As shown, a blasting vibration monitoring device for a super-large shaft includes a housing 1, a driver 2, a transmission module 3, a positioning module 4 and a monitoring module 5;

[0046] The housing 1 has a basic shape and thickness, and a cavity for installing a functional module is provided in the housing 1;

[0047] The driver 2 is arranged in the housing 1, and the output end of the driver 2 is connected to the transmission module 3. Accordingly, the transmission module 3 has an input end for connecting to the driver 2, at least two first output ends for connecting to the positioning module 4, and a second output end for connecting to the monitoring module 5.

[0048] The positioning module 4 is slidably disposed on the housing 1 and is used to fix the housing 1. Accordingly, at least two positioning modules 4 are provided and are evenly distributed on the circumference of the housing 1.

[0049] The monitoring module 5 is slidably disposed in the middle of the housing 1 and is used to monitor the vibration of the shaft;

[0050] Both the positioning module 4 and the monitoring module 5 have a first station received in the shell 1 and a second station extending outside the shell 1 . Accordingly, the shell 1 is provided with a first receiving hole adapted for the positioning module 4 and a second receiving hole adapted for the monitoring module 5 .

[0051] In the blasting vibration monitoring device for a super-large shaft, the housing 1 can be constructed in any suitable shape to adapt to different environments and expand the scope of use. The driver 2 is used to provide power to realize the movement of the positioning module 4 and the monitoring module 5. The transmission module 3 is used to transmit power, and the transmission module 3 is connected to the driver 2, the positioning module 4 and the monitoring module 5 at the same time, providing multiple output terminals, realizing one-to-many output of power, and reducing the number of drivers 2.

[0052] The positioning module 4 is used to fix the blasting vibration monitoring device for the extra-large shaft. Aiming at the special use environment of the shaft, the blasting vibration monitoring device for the extra-large shaft can be firmly set on the inner wall of the shaft to ensure the normal operation of the monitoring module 5. During the blasting construction, the monitoring module 5 is used to monitor the vibration of the shaft, and cooperates with the blasting vibration monitoring equipment on the ground to increase the data sample volume, which is helpful to comprehensively monitor the construction site, ensure construction safety, and facilitate subsequent improvement of construction methods.

[0053] Before blasting, the staff selects a suitable number of the blasting vibration monitoring devices for extra-large shafts, and then moves down the shaft with the lifting equipment, and places a blasting vibration monitoring device for extra-large shafts after moving down to a suitable position. The blasting vibration monitoring device for extra-large shafts is started and fixed on the shaft through the positioning module 4, and the monitoring module 5 is also made to stick to the inner wall surface of the shaft, that is, the positioning module 4 and the monitoring module 5 are both moved from the first station to the second station. Repeat the above operation until all the blasting vibration monitoring devices for extra-large shafts are placed.

[0054] After blasting, if the monitoring point changes, the staff will recover the corresponding blasting vibration monitoring device for the extra-large vertical shaft and deploy it at a new monitoring point; if the monitoring point is available during the next blasting, the staff will only need to inspect and maintain the corresponding blasting vibration monitoring device for the extra-large vertical shaft.

[0055] It is worth noting that if the blasting vibration monitoring device for a super-large shaft is used for a super-large shaft, the super-large shaft has a large depth and the bottom of the shaft is in a high temperature and high pressure environment. Accordingly, the blasting vibration monitoring device for a super-large shaft is made of high temperature and high pressure resistant materials to improve the adaptability to special environments. For the monitoring module 5, any suitable existing model of sensor is selected for monitoring, and a cooling module is provided on the detection module to enable the sensor to adapt to special environments.

[0056] Furthermore, the blasting vibration monitoring device for extra-large shafts can also be used for blasting monitoring in any other suitable sites. For example, in shafts of moderate depth, the blasting vibration monitoring device for extra-large shafts can use more materials to help reduce costs.

[0057] In a possible implementation, the transmission module 3 includes a first bevel gear 31, a second bevel gear 32 and a third bevel gear 33, the first bevel gear 31 and the second bevel gear 32 are spaced and arranged opposite to each other, and at least two third bevel gears 33 are provided and used to connect the first bevel gear 31 and the second bevel gear 32;

[0058] Correspondingly, the first bevel gear 31 is connected to the driver 2 , the second bevel gear 32 is connected to the monitoring module 5 , and the third bevel gear 33 is connected to the positioning module 4 .

[0059] Based on the above design scheme, by selecting bevel gears to form a multi-directional transmission structure, except for the first bevel gear 31 connected to the driver 2, the remaining bevel gears can be used to output power to the outside, increasing the number of output ends. The second bevel gear 32 simultaneously realizes the connection function and the power output function, ensuring that the multiple positioning modules 4 obtain power and work, and the setting of multiple second bevel gears 32 also helps to enhance the structural stability of the multi-directional transmission structure. The third bevel gear 33 is connected to the monitoring module 5 to adjust the position of the monitoring module 5.

[0060] It is easy to understand that the first bevel gear 31 and the third bevel gear 33 are preferably bevel gears of the same type and of any suitable model, and the second bevel gear 32 can be bevel gears of any suitable model and have any suitable number.

[0061] In a possible implementation, the positioning module 4 includes a base 41, a first transmission disc 42, a second transmission disc 43 and a positioning rod 44;

[0062] The base 41 is disposed in the housing 1;

[0063] The first transmission disc 42 has two opposite outer surfaces, one of which faces the base 41 and is connected to the first transmission cylinder 61. Accordingly, the first transmission disc 42 is rotatably arranged on the base 41 through the first transmission cylinder 61, and the other faces away from the base 41 and is provided with an adjustment groove. The adjustment groove is provided with an adjustment rod 45 that can reciprocate along the adjustment groove. Accordingly, the first transmission disc 42 is connected to the second transmission disc 43 through the adjustment rod 45.

[0064] The second transmission disc 43 has two opposite outer surfaces, one of which faces the first transmission disc 42 and is connected to the adjustment rod 45 to connect the first transmission disc 42 and the second transmission disc 43, and the other faces away from the first transmission disc 42 and is provided with an annular groove;

[0065] The positioning rod 44 is slidably disposed on the base 41 , and two ends of the positioning rod 44 are respectively configured as a connecting end slidably disposed in the annular groove and a positioning end for being plugged into the shaft.

[0066] Based on the above design, the power of the driver 2 is transmitted to the positioning module 4 through the transmission module 3 and the first transmission cylinder 61, so that the first transmission disk 42 and the second transmission disk 43 rotate, and the second transmission disk 43 is connected to the positioning rod 44 through the annular groove and drives the positioning rod 44 to slide back and forth along the base 41. Specifically: Figure 2 As shown, when the second transmission disk 43 rotates downward, the positioning rod 44 slides downward to the outside of the shell 1, so that the positioning end of the positioning rod 44 is inserted into the vertical shaft to achieve fixation and positioning; when the second transmission disk 43 rotates upward, the positioning rod 44 slides upward to the shell 1, so that the positioning end of the positioning rod 44 is disengaged from the vertical shaft to achieve separation from the vertical shaft.

[0067] Furthermore, an adjustment rod 45 is provided between the first transmission disc 42 and the second transmission disc 43. The adjustment rod 45 adjusts the position of the second transmission disc 43 by sliding back and forth along the adjustment groove, so that the second transmission disc 43 is eccentric relative to the first transmission disc 42. Figure 2 For example, when the second transmission disc 43 is eccentric to the first transmission disc 42 and rotates downward, the second rotating disc rotates downward a greater distance, and the positioning rod 44 extends outward a greater length, thereby increasing the length of the positioning rod 44 inserted into the shaft, and the fixing effect is better. Similarly, when the second transmission disc 43 rotates upward, the positioning rod 44 is retracted and separated from the shaft.

[0068] Therefore, the positioning module 4 can not only control the reciprocating sliding of the positioning rod 44 to achieve its fixing function, but also control the extension length of the positioning rod 44 to improve the fixing effect, thereby adapting to different usage environments.

[0069] Alternatively, if Figure 3As shown, the first transmission disc 42 is provided with a convex seat body 46 on the outer surface facing away from the base 41, and the adjustment groove is provided on the seat body 46. Based on this, the spacing between the first transmission disc 42 and the second transmission disc 43 is increased by the arrangement of the seat body 46, which is convenient for arranging the adjustment rod 45.

[0070] Optionally, the base 41 may be configured in any suitable shape.

[0071] It is easy to understand that if the primary support is constructed on the shaft, a hole adapted to the positioning rod 44 is reserved on the primary support so that the positioning rod 44 can be inserted into the corresponding hole to achieve the fixation of the blasting vibration monitoring device for the extra-large shaft. At this time, preferably, an elastic layer is provided on the outside of the positioning rod 44. When the positioning rod 44 is inserted into the hole, the elastic layer is deformed and pressed tightly to further ensure the fixation effect.

[0072] In a possible implementation, the adjustment rod 45 includes a reciprocating motor and a threaded rod, the reciprocating motor is arranged on the housing 1, the output end of the reciprocating motor is connected to the threaded rod, the threaded rod is rotatably arranged on the adjustment groove, and accordingly, the adjustment groove is configured as a threaded groove;

[0073] When the threaded rod rotates, the second transmission disc 43 moves relative to the first transmission disc 42 , so that the second transmission disc 43 is eccentric relative to the first transmission disc 42 , so as to adjust the sliding range of the positioning rod 44 .

[0074] Based on the above design, the reciprocating motor is used to provide power and enables the threaded rod to reciprocate to flexibly adjust the eccentricity of the second transmission disc 43 relative to the first transmission disc 42. The threaded rod is threadedly connected to the adjustment groove, which not only has effective transmission, but also makes the structure compact and saves space.

[0075] Optionally, an outwardly protruding shaft body is provided on the threaded rod, and accordingly, the threaded rod is connected to the second transmission plate 43 via the shaft body, and an opening adapted to the shaft body is provided on the adjustment groove.

[0076] In one possible implementation, a first transmission mechanism 6 is provided between the third bevel gear 33 and the positioning module 4, and the first transmission mechanism 6 includes a first transmission cylinder 61, a first transmission rod 62 and a second transmission cylinder 63. One end of the first transmission cylinder 61 is connected to the first transmission disk 42, and the other end of the second transmission cylinder 63 is connected to the second transmission cylinder 63 through the first transmission rod 62. The second transmission cylinder 63 is connected to the third bevel gear 33, and the first transmission rod 62 is constructed as a screw. Accordingly, the first transmission cylinder 61 and the second transmission cylinder 63 are provided with matching threads.

[0077] Based on the above design scheme, the first transmission mechanism 6 is used to connect the third bevel gear 33 and the positioning module 4. Specifically, the second transmission cylinder 63 is fixedly connected to the third bevel gear 33. When the third bevel gear 33 rotates, the second transmission cylinder 63 rotates, so that the first transmission rod 62 and the first transmission cylinder 61 also rotate together, thereby realizing power transmission.

[0078] Furthermore, the positioning module 4 is provided with an adjusting rod 45 to make the second transmission disc 43 eccentric relative to the first transmission disc 42, thereby controlling the extension length of the positioning rod 44. Based on this, the length of the first transmission mechanism 6 can be appropriately reduced, making the structure compact and reducing space occupation.

[0079] It is worth noting that there are at least two positioning modules 4 and at least two third bevel gears 33. Accordingly, there are at least two first transmission mechanisms 6. In different first transmission mechanisms 6, the thread rotation directions of the first transmission rods 62 are different, so that the positioning rods 44 of multiple positioning modules 4 can be raised and lowered synchronously.

[0080] Based on the above design, since the third bevel gear 33 needs to output power to the positioning module 4, the third bevel gear 33 is relatively fixed between the first bevel gear 31 and the second bevel gear 32, that is, the third bevel gear 33 will rotate on its own, but will not revolve around the first bevel gear 31. Figure 1 As shown, the rotation directions of the two third bevel gears 33 are different. Therefore, the first transmission mechanism 6 realizes the synchronous movement of the two positioning modules 4 by changing the rotation direction of the thread, so that the positioning rods 44 in the two positioning modules 4 slide outward or retract inward synchronously, thereby ensuring the fixing effect.

[0081] In a possible implementation, three positioning modules 4, three third bevel gears 33 and three first transmission mechanisms 6 are provided respectively, and the positioning modules 4, the third bevel gears 33 and the first transmission mechanisms 6 are provided in a one-to-one correspondence. Based on the above design scheme, according to actual construction conditions, the number of positioning modules 4, the third bevel gears 33 and the first transmission mechanisms 6 can be uniformly increased or decreased to ensure the monitoring effect.

[0082] Furthermore, according to the number of positioning modules 4, third bevel gears 33 and first transmission mechanisms 6, the blasting vibration monitoring device for extra-large shafts can be provided with multiple models for selection by staff, which is more flexible and convenient to use.

[0083] In a possible implementation, the monitoring module 5 includes a base plate 51, a monitoring sheet 52 and a cooling element;

[0084] The base plate 51 is slidably disposed on the housing 1. The base plate 51 has two opposite outer surfaces, one of which faces the transmission module 3 and is connected to the transmission module 3 through the second transmission mechanism 7, and the other faces outward and is provided with a monitoring groove adapted to the monitoring piece 52. Accordingly, the monitoring piece 52 is detachably disposed on the monitoring groove.

[0085] A cooling groove and a cover plate surrounding the second transmission mechanism 7 are provided on the base plate 51. Accordingly, the cooling element is placed in the cooling groove, and the cover plate is used to close the cooling groove.

[0086] Based on the above design, the base plate 51 is connected to the transmission module 3, specifically the second bevel gear 32, through the second transmission mechanism 7, so that the monitoring module 5 slides relative to the housing 1. When the monitoring module 5 slides outward, the monitoring piece 52 abuts against the inner wall of the shaft to facilitate the measurement of the vibration of the shaft during blasting. Conversely, when the monitoring module 5 slides inward, the monitoring piece 52 is retracted into the housing 1.

[0087] The base plate 51 is connected to the monitoring piece 52 by any suitable detachable connection method, so that different types of monitoring pieces 52 can be replaced according to different use environments to improve the adaptability of monitoring. At the same time, through the cooperation of the cooling groove, the cover plate and the cooling element, the cooling element is fixed on the base plate 51 and cools the monitoring piece 52 to adapt to the high temperature environment.

[0088] In a possible implementation, the monitoring sheet 52 is a strain gauge sensor. It is easy to understand that the monitoring sheet 52 can also be any other suitable existing sensor.

[0089] In a possible implementation, the cooling element is a solid coolant. It is easy to understand that the cooling element can also be any other suitable existing cooling component.

[0090] In a possible implementation, the second transmission mechanism 7 includes a third transmission cylinder 71, a second transmission rod 72, an intermediate plate 73 and a lifter 74;

[0091] The third transmission cylinder 71 has two opposite ends, one of which is provided with a convex transmission block 75 on its periphery, and accordingly, the third transmission cylinder 71 is connected to the transmission module 3 via the transmission block 75, and the other end is provided with a concave threaded hole, and accordingly, the second transmission rod 72 is rotatably arranged on the threaded hole, and the second transmission rod 72 is provided with an adapted thread;

[0092] The middle plate 73 is sleeved on the third transmission cylinder 71 . The lifter 74 is disposed in the housing 1 and connected to the middle plate 73 . The lifter 74 is used for lifting and lowering the third transmission cylinder 71 to control whether the transmission block 75 is connected to the transmission module 3 .

[0093] Based on the above design, the third transmission cylinder 71 and the second transmission rod 72 are also threadedly connected to achieve transmission, thereby realizing the reciprocating sliding of the monitoring module 5 .

[0094] Furthermore, in general, the third transmission cylinder 71 is connected to the transmission module 3, specifically the second bevel gear 32, through the transmission block 75 to ensure that power can be transmitted. However, if the movement distances of the positioning module 4 and the monitoring module 5 are different, in order to prevent the monitoring sheet 52 from being over-pressed, the third transmission cylinder 71, the second transmission rod 72, the middle plate 73 and the monitoring module 5 are moved by the lifter 74, so that the transmission block 75 of the third transmission cylinder 71 is disengaged from the second bevel gear 32, and the positioning module 4 and the monitoring module 5 are asynchronously moved, thereby protecting the monitoring sheet 52. When the monitoring module 5 needs to move again, the lifter 74 is reset so that the third transmission cylinder 71 is connected to the second bevel gear 32 again through the transmission block 75.

[0095] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
