Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, specifically to an intelligent vibration monitoring and fault early warning device for rock drills. Background Technology

[0002] A rock drill is an engineering machine that uses impact, rotation, or a combination of actions to drill holes in hard media such as rock and concrete. It is widely used in mining, tunneling, construction, and geological exploration. In traditional rock drill operations, vibration monitoring and fault warning relied mainly on the experience of operators. Workers would roughly judge whether there were potential faults by sensing abnormal sounds and changes in vibration amplitude during operation. However, this method is highly subjective, with different operators having different judgment standards, and it is difficult to detect some subtle potential faults in advance. With the rapid development of technology, a device that can perform intelligent vibration monitoring and fault warning for rock drills has emerged on the market, which can ensure stable operation of the equipment and improve production efficiency.

[0003] Existing monitoring and early warning devices are widely used, but they are inconvenient to fix to the rock drill rod of the rock drill during use. They can only be placed in the rock area where the rock drill is working for vibration monitoring, or fixed to the rock drill rod with tools such as tape. The monitoring is not accurate enough. Therefore, in order to solve the above problems, an intelligent vibration monitoring and fault early warning device for rock drills is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent vibration monitoring and fault early warning device for rock drills, so as to solve the problem mentioned in the background art that the existing devices are not convenient to fix on the rock drill rod.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Two positioning rings are fixedly connected to the outer side of the rock drill rod. The positioning rings have symmetrically symmetrically arranged vertical positioning holes that penetrate the positioning rings. A mounting plate is fixedly connected to the side of the monitoring head near the rock drill rod. A symmetrically arranged semi-open ring is rotatably connected to the side of the mounting plate away from the monitoring head. The semi-open ring has symmetrically arranged vertically arranged limiting grooves inside. A limiting component is installed inside the limiting groove. Bolts are symmetrically installed at the upper and lower ends of the limiting component. The bolts are inserted into the positioning holes, and nuts are spirally connected to the outer side of the bolts.

[0007] Preferably, the limiting component includes a fixed plate fixedly connected to the center of the inner side of the limiting groove, and limiting springs symmetrically arranged are fixedly connected to the upper and lower ends of the fixed plate. A sliding plate is fixedly connected to the end of the limiting spring away from the fixed plate, and a handle is fixedly connected to the outer side of the sliding plate.

[0008] Preferably, the connection between the slide plate and the limiting groove is a sliding connection, the handle is located outside the semi-open ring and is slidably connected to the semi-open ring, and the end of the slide plate away from the limiting spring is fixedly connected to a bolt.

[0009] Preferably, a rubber magnetic ring is fixedly connected to the inner side of the semi-open ring, and a slot is opened on the inner side of the rubber magnetic ring. A locking block is symmetrically provided between the two positioning rings and fixedly connected to the outside of the rock drill rod.

[0010] Preferably, the inner side of the rubber magnetic ring is tightly fitted to the outer side of the rock drill rod, and the locking block is located inside the slot and engaged with the slot.

[0012] 1. In this utility model, the monitoring and early warning device, monitoring head, rock drill rod, positioning ring, positioning hole, mounting plate, semi-open ring, limiting groove, limiting component, bolt and nut are set up. When the device needs to be installed, the handle on the semi-open ring is moved to retract the bolt into the limiting groove. Next, the semi-open ring is moved between the two positioning rings, the handle is released, the limiting spring returns to its original position, and the bolt is inserted into the positioning hole. Finally, the nut is screwed on the outside of the bolt to complete the installation of the monitoring head. The design of the limiting component and its connecting component can easily and firmly fix the monitoring head on the rock drill rod, making the monitoring data more accurate.

[0013] 2. In this utility model, by setting a rubber magnetic ring, a slot, and a block, when the semi-open ring is moved between the two positioning rings, the semi-open ring is rotated appropriately so that the slot on the rubber magnetic ring corresponds to the position of the block, and the two semi-open rings are closed, so that the rubber magnetic ring is attracted to the outside of the rock drill rod, and the block is located inside the slot and engaged with the slot. At this time, the bolt is vertically aligned with the positioning hole on the positioning ring. The setting of the rubber magnetic ring, slot, and block can make the bolt accurately aligned with the positioning hole, making it more convenient for the operator to install the semi-open ring.

[0024] A smart vibration monitoring and fault early warning device for a rock drill includes a monitoring and early warning device 1, a monitoring head 2 fixedly connected to the monitoring and early warning device 1, and a rock drill rod 3 located on one side of the monitoring head 2. Two positioning rings 4 are fixedly connected to the outer side of the rock drill rod 3. The positioning rings 4 have symmetrically symmetrically arranged vertical positioning holes 5. A mounting plate 6 is fixedly connected to the side of the monitoring head 2 near the rock drill rod 3. A symmetrically arranged semi-open ring 7 is rotatably connected to the side of the mounting plate 6 away from the monitoring head 2. A vertically arranged limiting groove 8 is symmetrically arranged inside the semi-open ring 7. A limiting component 9 is installed inside the limiting groove 8. Bolts 10 are symmetrically installed at the upper and lower ends of the limiting component 9. The bolts 10 are inserted into the inner side of the positioning holes 5. Nuts 11 are screwed to the outer side of the bolts 10. The limiting component 9 includes a fixing plate 91 fixedly connected to the center of the inner side of the limiting groove 8. A symmetrically arranged limiting spring 92 is fixedly connected to the upper and lower ends of the fixing plate 91. The end of the limiting spring 92 away from the fixing plate 91 is fixedly... A sliding plate 93 is fixedly connected to the outside of the sliding plate 93, and a handle 94 is fixedly connected to the outside of the sliding plate 93. The connection between the sliding plate 93 and the limiting groove 8 is a sliding connection. The handle 94 is located outside the semi-open ring 7 and is slidably connected to the semi-open ring 7. The end of the sliding plate 93 away from the limiting spring 92 is fixedly connected to the bolt 10. Through the monitoring and early warning device 1, monitoring head 2, rock drill rod 3, positioning ring 4, positioning hole 5, mounting plate 6, semi-open ring 7, limiting groove 8, limiting component 9, bolt 10 and nut 11, when the device needs to be installed, move the handle 94 on the semi-open ring 7 so that the bolt 10 retracts into the inner side of the limiting groove 8. Next, move the semi-open ring 7 between the two positioning rings 4, release the handle 94, and the limiting spring 92 resets, causing the bolt 10 to be inserted into the inner side of the positioning hole 5. Finally, screw the nut 11 on the outside of the bolt 10 to complete the installation of the monitoring head 2. The design of the limiting component 9 and its connecting components can easily and firmly fix the monitoring head 2 to the rock drill rod 3, making the monitoring data more accurate.

[0025] A rubber magnetic ring 12 is fixedly connected to the inner side of the semi-open ring 7. A groove 13 is provided on the inner side of the rubber magnetic ring 12. A locking block 14 is symmetrically provided between the two positioning rings 4 and fixedly connected to the outer side of the rock drill rod 3. The inner side of the rubber magnetic ring 12 is tightly fitted to the outer side of the rock drill rod 3. The locking block 14 is located inside the groove 13 and is engaged with the groove 13. Through the rubber magnetic ring 12, the groove 13 and the locking block 14, when the semi-open ring 7 is moved between the two positioning rings 4, it rotates appropriately. The open ring 7 aligns the slot 13 on the rubber magnetic ring 12 with the position of the locking block 14, and the two half-open rings 7 are closed, so that the rubber magnetic ring 12 is attracted to the outside of the rock drill rod 3. The locking block 14 is located inside the slot 13 and is engaged with the slot 13. At this time, the bolt 10 is vertically aligned with the positioning hole 5 on the positioning ring 4. The arrangement of the rubber magnetic ring 12, the slot 13 and the locking block 14 can make the bolt 10 accurately aligned with the positioning hole 5, making it more convenient for the operator to install the half-open ring 7.

[0026] Workflow: Before use, power on the device. When using the device, first open the two semi-open rings 7 on the mounting plate 6. The user places both hands on the handles 94 on the two semi-open rings 7 and moves the handles 94, causing the slide plate 93 on one side of the handle 94 to slide inside the limiting groove 8. The limiting springs 92 at the upper and lower ends of the fixing plate 91 are compressed, and the bolt 10 retracts into the limiting groove 8. Next, move the semi-open rings 7 between the two positioning rings 4 on the rock drill rod 3, and align the slot 13 on the rubber magnetic ring 12 with the position of the locking block 14. Close the two semi-open rings 7, so that the rubber magnetic ring 12 is attracted to the outside of the rock drill rod 3, and the locking block 14 is located inside the slot 13 and engaged with the slot 13. At this time, the bolt 10 is vertically aligned with the positioning hole 5 on the positioning ring 4. Release the handle 94, and the limiting spring 92 returns to its original position, causing the slide plate 93 to slide inside the limiting groove 8 until the bolt 10 is inserted into the positioning hole 5. The rubber magnetic ring 12, the slot 13, and the locking block 14 inside the positioning hole 5 enable the bolt 10 to be accurately aligned with the positioning hole 5, making it easier for the operator to install the semi-open ring 7. Finally, the nut 11 is screwed onto the outside of the bolt 10 to complete the installation of the monitoring head 2. When using the rock drill, the monitoring head 2 can transmit the vibration signal of the rock drill rod 3 to the monitoring and early warning device 1. The monitoring and early warning device 1 can determine whether the vibration of the rock drill is normal. If the vibration is abnormal, it can provide an early warning of the rock drill's malfunction. The design of the limit component 9 and its connecting components can easily and firmly fix the monitoring head 2 to the rock drill rod 3, making the monitoring data more accurate. After the monitoring is completed, the nut 11 is removed from the bolt 10, and the handle 94 is moved to make the bolt 10 disengage from the positioning hole 5 on the positioning ring 4. The semi-open ring 7 can then be opened to remove the monitoring head 2. This design makes the installation and removal of the monitoring head 2 simple and secure.
