Description

Technical Field

[0001] This application relates to the field of vibration testing technology, and in particular to a vibration testing device for a rock drill. Background Technology

[0002] Rock drills are construction equipment widely used in stone quarrying, rock excavation, and concrete breaking. They drill holes in rock strata or hard layers to facilitate subsequent blasting operations. Because rock drills generate vibration during operation, rigorous performance and strength testing is required after manufacturing to ensure that the vibration amplitude meets standards, maintain handheld stability, and prevent severe vibration from affecting construction results and operator safety. Vibration testing is one of the key testing items.

[0003] Currently, existing rock drill vibration testing devices typically use multiple sets of bolts to secure the rock drill to the top of the test platform. While this method ensures the stability of the rock drill during testing, it has significant shortcomings in practical operation. When vibration testing is required on multiple rock drills of different models or sizes, the frequent disassembly and reassembly of bolts is not only time-consuming and labor-intensive, greatly reducing testing efficiency, but also increases the complexity and difficulty of the testing work, causing considerable inconvenience to testing personnel.

[0004] In order to overcome the shortcomings of existing technologies, improve the efficiency and convenience of rock drill vibration testing, and ensure the safety and reliability of the testing process, this application proposes a vibration testing device for rock drills. By improving the existing fixing method, it enables the rapid installation and disassembly of rock drills, reducing the time and labor intensity of bolt operation. Utility Model Content

[0005] This invention provides a vibration testing device for rock drills.

[0006] The specific technical solution is as follows: A vibration testing device for a rock drill includes a base plate. Four first support columns are installed on one side of the top of the base plate, and four second support columns are installed on the other side. A support mechanism is installed above the four first support columns, which supports the rotating parts of the handheld rock drill. A fixing mechanism is installed above the four second support columns, which supports the body of the handheld rock drill. The fixing mechanism includes a fixing plate with a fixing groove. A fixing disc is movably installed in the fixing groove, and the arc-shaped surface at the top of the fixing disc is connected to the body of the handheld rock drill.

[0007] Furthermore, preferably, at least one set of fixing holes are symmetrically provided on both sides of the fixing plate, and fixing rods corresponding to the fixing holes are provided in the fixing plates on both sides of the fixing groove. The fixing rods are slidably disposed in the mounting groove. One end of the mounting groove is connected to the fixing groove, and the other end is connected to the sliding groove. The mounting groove and the sliding groove are opened inside the fixing plate, and the top of the sliding groove extends to the top surface of the fixing plate. A second limiting plate is provided on the outer surface of the fixing rod on the side of the mounting groove closer to the fixing groove. A fixing spring is sleeved on the outer surface of the fixing rod between the mounting groove and the second limiting plate. A lever is connected to the end of the fixing rod away from the fixing groove. The other end of the lever extends through the sliding groove to the top surface of the fixing plate. The lever is used to pull the fixing rod to slide in the sliding groove and the mounting groove.

[0008] Furthermore, preferably, a connecting rod is connected to the top of the lever.

[0009] Furthermore, preferably, a clamping mechanism is also provided on the fixing plate on the outside of the connecting rod.

[0010] Furthermore, preferably, the clamping mechanism includes a T-shaped clamping block, the two sides of which are slidably disposed in a sliding groove, the sliding groove being formed on a fixed plate directly below the T-shaped clamping block, and at least one clamping spring connecting the T-shaped clamping block and the sliding groove.

[0011] Furthermore, preferably, the bottom of the sliding slot is provided with two first protrusions, and the bottom of the T-shaped block is provided with two second protrusions. The two first protrusions and the two second protrusions are perpendicularly corresponding to each other, and the two ends of the clamping spring are respectively clamped on the outer surfaces of the corresponding first protrusions and second protrusions.

[0012] Furthermore, preferably, the support mechanism includes a support plate, on which two sets of sliding rods are slidably disposed, with a first limiting plate connected to the bottom end of each sliding rod, and the top ends of all sliding rods connected to the same mounting frame. Two rollers are symmetrically mounted on the top of the mounting frame via bearings, and a support spring is sleeved on the outer surface of the sliding rod located between the support plate and the mounting frame.

[0013] The beneficial effects of this invention are as follows: Through the cooperation of the fixed rod and fixed hole, and the assistance of the clamping mechanism, this device ensures the safety and reliability of the rock drill during high-frequency vibration testing, while also enabling rapid fixing and disassembly of the rock drill. Its advantage of rapid replacement is particularly prominent when multiple sets of different models of rock drills are tested continuously. Compared to traditional bolt fixing methods, it significantly reduces the time and labor intensity required for installation and disassembly, substantially improving the overall efficiency of vibration testing. Simultaneously, the fixing plate is movably installed in the fixing groove, and the size and shape of the fixing plate can be adjusted according to different models of rock drills, making the device compatible with rock drills of different sizes and models, possessing good versatility and flexibility to meet various testing needs. Furthermore, the support mechanism, through the design of springs and rollers, can automatically adjust the support force and position according to the weight and size of the rotating parts of the rock drill, further enhancing the device's adaptability to different rock drills and ensuring stable support under various conditions.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1 As shown, the vibration testing device for a rock drill provided in this embodiment includes a base plate 1. Four first support columns 101 are installed on one side of the top of the base plate 1, and four second support columns 102 are installed on the other side. A support mechanism 2 is installed above the four first support columns 101 to support the rotating parts of the handheld rock drill 7. A fixing mechanism 3 is installed above the four second support columns 102 to support the body of the handheld rock drill 7.

[0024] like Figure 3 As shown, the fixing mechanism 3 includes a fixing plate 301 with a fixing groove 302. A fixing disk 701 is movably installed in the fixing groove 302, and the arc-shaped surface at the top of the fixing disk 701 is connected to the body of the handheld rock drill 7. This movable installation method allows for quick installation and disassembly of the handheld rock drill 7, significantly improving the efficiency and convenience of vibration testing. Furthermore, this fixing method can adapt to different models or sizes of rock drills, exhibiting good versatility and flexibility, thus meeting the testing needs of various models.

[0025] As a preferred embodiment, such as Figure 1 Figure 3As shown, the fixed plate 701 has two sets of fixed insertion holes 702 (i.e., four fixed insertion holes 702) symmetrically opened on both sides. The fixed plates 301 on both sides of the fixed groove 302 are slidably provided with two sets of fixed insertion rods 305 (i.e., four fixed insertion rods 305) corresponding to the two sets of fixed insertion holes 702. By inserting or withdrawing the fixed insertion rods 305 into or out of the fixed insertion holes 702, the fixed plate 701 can be quickly installed or removed.

[0026] Specifically, such as Figure 3 Figure 4 As shown, the fixed insertion rod 305 is slidably disposed in the mounting groove 303; one end of the mounting groove 303 is connected to the fixed groove 302, and the other end is connected to the sliding groove 304; the mounting groove 303 and the sliding groove 304 are formed inside the fixed plate 301, and the top of the sliding groove 304 extends to the top surface of the fixed plate 301; a second limiting plate 306 is provided on the outer surface of the fixed insertion rod 305 on the side of the mounting groove 303 near the fixed groove 302, and a fixed spring 307 is sleeved on the outer surface of the fixed insertion rod 305 between the mounting groove 303 and the second limiting plate 306; a lever 308 is connected to the end of the fixed insertion rod 305 away from the fixed groove 302, and the other end of the lever 308 extends through the sliding groove 304 to the top surface of the fixed plate 301.

[0027] In use, pull all four levers 308 simultaneously in the direction away from the fixing groove 302. The levers 308 will cause the fixing rod 305 to slide towards the slide groove 304, compressing the fixing spring 307 until the fixing rod 305 is completely removed from the fixing groove 302. At this time, place the fixing plate 701 into the fixing groove 302, and then release the levers 308. Under the rebound action of the fixing spring 307, the fixing rod 305 will return to its original position, slide out of the mounting groove 303, and insert into the corresponding fixing hole 702, thereby firmly fixing the handheld rock drill 7 onto the fixing groove 302.

[0028] Furthermore, to facilitate pulling the lever 308, the tops of the two levers 308 on the same side are connected to the same connecting rod 309.

[0029] Furthermore, in order to better control the movement of the connecting rod 309, such as... Figure 3 Figure 5As shown, a clamping mechanism 5 is also provided on the fixing plate 301 on the outer side of the connecting rod 309. The clamping mechanism 5 includes a T-shaped clamping block 501, which is slidably disposed on both sides in the sliding groove 4. The sliding groove 4 is opened on the fixing plate 301 directly below the T-shaped clamping block 501. The bottom of the sliding groove 4 is provided with two first protrusions 401 and the bottom of the T-shaped clamping block 501 is provided with two second protrusions 502. The two first protrusions 401 and the two second protrusions 502 are vertically corresponding to each other, and the first protrusions 401 and the second protrusions 502 are connected to the same clamping spring 6. The two ends of the clamping spring 6 are respectively clamped on the outer surfaces of the corresponding first protrusions 401 and second protrusions 502 to ensure that the clamping spring 6 will not be displaced when compressed and deformed, thereby ensuring that the T-shaped clamping block 501 slides vertically up and down along both sides of the sliding groove 4 and will not disengage from the sliding groove 4.

[0030] In use, pulling the two sets of connecting rods 309 causes the lever 308 and the fixed insert 305 to move outward. When the connecting rod 309 contacts the T-shaped locking block 501, the T-shaped locking block 501 is pressed and moves downward along the sliding groove 4, compressing the two clamping springs 6. After the connecting rod 309 passes the T-shaped locking block 501, the T-shaped locking block 501 resets under the rebound action of the clamping springs 6, thus abutting against the inner side of the connecting rod 309 to limit its movement and prevent the fixed insert 305 from failing to spring back. When the fixed insert 305 needs to spring back and reset, simply press down on the T-shaped locking block 501 to release the restriction of the T-shaped locking block 501 on the connecting rod 309, allowing the fixed insert 305 to spring back and reset under the action of the fixed spring 307.

[0031] As a further preferred solution in this embodiment, such as Figure 2 As shown, the support mechanism 2 includes a support plate 201. Two sets of sliding rods 202 are slidably mounted on the support plate 201. Each sliding rod 202 has a first limiting plate 203 connected to its bottom end. The top ends of all sliding rods 202 are connected to the same mounting frame 204. Two rollers 206 are symmetrically mounted on the top of the mounting frame 204 via bearings. Support springs 205 are sleeved on the outer surface of the sliding rods 202 located between the support plate 201 and the mounting frame 204. When the rotating part of the handheld rock drill 7 contacts the two sets of rollers 206, the mounting frame 204 and rollers 206 are pressed down under the weight of the rotating part. At this time, under the elastic action of the support springs 205, the mounting frame 204 and rollers 206 receive an upward elastic force, thereby ensuring that the two sets of rollers 206 are tightly fitted to the rotating part of the handheld rock drill 7, providing good support. This design not only effectively supports the rotating part of the rock drill, preventing it from tipping over due to uneven weight distribution, but also maintains the stability of the rock drill during vibration testing.

[0032] Working principle: Pulling the connecting rod 309 to both sides away from the fixing groove 302 causes the lever 308 and the fixing rod 305 to move outwards until the fixing rod 305 is completely away from the fixing groove 302. During this process, when the connecting rod 309 contacts the T-shaped locking block 501, the T-shaped locking block 501 is pressed downwards and slides, allowing the connecting rod 309 to smoothly pass over the T-shaped locking block 501. Subsequently, under the rebound action of the locking spring 6, the T-shaped locking block 501 moves upwards and resets, locking and fixing the connecting rod 309 to ensure that the fixing rod 305 will not spring back to its original position.

[0033] Insert the fixing plate 701 on the outer surface of the handheld rock drill 7 into the fixing groove 302, aligning the fixing hole 702 with the fixing rod 305. Press down the T-shaped locking block 501, and under the rebound action of the fixing spring 307, the two sets of fixing rods 305 return to their original position, extend out of the mounting groove 303, and insert into the corresponding fixing hole 702, thereby fixing the handheld rock drill 7 onto the fixing groove 302.

[0034] Simultaneously, the rotating part of the handheld rock drill 7 contacts the two sets of rollers 206. Under the gravity of the rotating part, the mounting frame 204 and rollers 206 are pressed down. At this time, under the elastic action of the support spring 205, the mounting frame 204 and rollers 206 obtain an upward elastic force, thereby ensuring that the two sets of rollers 206 are tightly attached to the rotating part of the handheld rock drill 7, providing support. At this time, the handheld rock drill 7 is firmly fixed on top of the support mechanism 2 and the fixing mechanism 3, and the vibration of the handheld rock drill 7 in the working state can be tested by an external vibration sensor.

[0035] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
