Description

Technical Field

[0001] This utility model relates to the field of rock mining technology, specifically a double splitting mechanism and an integrated drilling and splitting machine. Background Technology

[0002] In the field of non-blasting construction in hard rock, integrated drilling and splitting machines are increasingly being used. Current integrated drilling and splitting machines primarily use a drilling rig to drill holes. After drilling, a hydraulic wedge assembly on the splitting machine is used to split the rock, creating cracks. Then, a hydraulic breaker is used to further split the rock. The main principle is that rock has much lower tensile strength than compressive strength, making it much easier to split from the inside than from the outside. The splitting machine, however, drills holes and then uses a hydraulic cylinder to press a wedge structure, generating a strong splitting force to split the rock from the inside. Because of its wedge structure, its splitting stroke is relatively small, resulting in smaller cracks. The relatively small rock cracks and incomplete splitting lead to longer working times and higher crushing costs for the subsequent hydraulic breaker operation. Utility Model Content

[0003] The purpose of this utility model is to provide a double splitting mechanism and an integrated drilling and splitting machine. The double splitting mechanism can achieve a large stroke splitting of the rock, which facilitates the subsequent use of a hydraulic breaker to achieve efficient rock crushing, thereby improving the overall rock crushing and mining efficiency.

Detailed Implementation

[0017] The following will describe specific embodiments and appendices. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] This utility model provides a double splitting mechanism (such as...) Figure 1As shown, the rock splitter includes a connecting frame 1, a slewing system 2, a frame 3, a first rock splitter 5, and a second rock splitter 6. In practical applications, the connecting frame 1 is used to connect the mechanism to external equipment, such as connecting it to the front end of the boom of an existing excavator, allowing the excavator to be used to adjust the position of the entire mechanism. The first rock splitter 5 is a well-known and mature wedge-type rock splitter in the field of rock mining technology; therefore, the specific structure of the first rock splitter 5 will not be described in detail here. The working principle of the first rock splitter 5 is to use the first rock splitter cylinder 52 to drive the splitting blocks 54 to expand outward, generating a huge thrust to make the rock move along a predetermined direction. The first rock splitter 5 has a large splitting force, but the width of the crack it creates is limited, making it suitable for creating initial fractures. The second rock splitter 6 can be a wedge-type rock splitter or a rock splitter with a relatively large splitting stroke, which are known and mature in the field of rock mining technology. Therefore, the specific structure of wedge-type rock splitters and rock splitters with a relatively large splitting stroke will not be described in detail here. In this specific embodiment, the second rock splitter 6 preferably uses a rock splitter with a relatively larger splitting stroke. The working principle of the rock splitter is to drive the rod body to extend and retract through hydraulic power, generating static pressure expansion force inside the rock, causing the rock mass to continuously split along the weak surface. Its splitting stroke is long and controllable, making it suitable for the gradual expansion and widening of cracks.

[0019] The frame 3 is connected to the connecting frame 1 via a rotary system 2. The rotary system 2 can drive the frame 3 to rotate freely. In this specific embodiment, the rotary system 2 can be a hydraulic rotary system commonly used in the field of existing engineering machinery. It mainly includes a first drive motor 21 and a first slewing bearing 22. The outer ring of the first slewing bearing 22 is fixedly mounted on the lower part of the connecting frame 1 by bolts. The first drive motor 21 is fixedly mounted on the connecting frame 1. A first drive wheel is mounted on the output shaft of the first drive motor 21. The first drive wheel meshes with the inner ring of the first slewing bearing 22. The upper part of the frame 3 is fixedly connected to the lower part of the inner ring of the first slewing bearing 22 by bolts. Therefore, the rotation of the first drive wheel can realize the rotation drive of the frame 3. The first splitter 5 and the second splitter 6 are spaced apart on the frame. In practical applications, the position of the first rock splitter 5 and the second rock splitter 6 can be adjusted by rotating the frame 3, thereby facilitating the orderly connection of the initial splitting operation and the secondary splitting operation, thus improving the efficiency of rock mining and splitting. The first rock splitter 5 can rotate freely, move up and down and be positioned on the frame 3. With the ability of the first rock splitter 5 to rotate freely, move up and down and be positioned on the frame 3, it is easy to adjust the working angle and position of the first rock splitter 5 so as to achieve directional splitting of the rock. The second rock splitter 6 can rotate freely, move up and down and be positioned on the frame 3. With the ability of the second rock splitter 6 to rotate freely, move up and down and be positioned on the frame 3, the depth and angle of the second rock splitter 6 inserted into the rock fissure can be precisely controlled to achieve continuous expansion and directional widening of the crack.

[0020] Based on the above embodiments, to facilitate efficient coordination between the first rock splitter 5 and the second rock splitter 6 during operation, the first rock splitter 5 and the second rock splitter 6 are spaced apart along the circumferential direction of the rotary system 2, and the central axes of the first rock splitter 5 and the second rock splitter 6 are both located on a circumference 101 coaxial with the central axis of the rotary system 2. Utilizing the above-mentioned positional distribution of the first rock splitter 5 and the second rock splitter 6, when adjusting their working positions, only the frame 3 needs to be rotated without requiring further movement or adjustment. When the frame 3 rotates under the drive of the rotary system 2, the first rock splitter 5 and the second rock splitter 6 can be sequentially aligned with the same working surface, achieving continuous and efficient operation with the first rock splitter 5 splitting and the second rock splitter 6 widening the crack.

[0021] Based on the above embodiments, the specific implementation method for the first rock splitter 5 to achieve free rotation, vertical movement, and positioning on the frame 3 is as follows: A first rock splitter rotation drive system 51 and a first lifting mechanism are provided on the frame 3. The first rock splitter 5 is mounted on the first rock splitter rotation drive system 51, and the first rock splitter rotation drive system 51 can drive the first rock splitter 5 to rotate around its own axis. The first lifting mechanism is mounted on the frame 3, and the first lifting mechanism can drive the first rock splitter rotation drive system 51 and the first rock splitter 5 as a whole to move vertically and position vertically. Specifically, the first lifting mechanism includes a first hydraulic cylinder 53 and a first sliding support seat 55. The first sliding support seat 55 is slidably mounted on the frame 3. The first hydraulic cylinder 53 is mounted on the frame 3, and the extension end of the first hydraulic cylinder 53 is connected to the first sliding support seat. The first rock splitter rotation drive system 51 is mounted on the first sliding support seat 55, utilizing... The reciprocating movement of the first hydraulic cylinder 53 enables the reciprocating up-and-down movement of the first sliding support 55. The first rock splitter rotary drive system 51 can be a hydraulic drive rotary system commonly used in the field of existing engineering machinery. It includes a second drive motor and a second slewing bearing. The outer ring of the second slewing bearing is fixedly connected to the support frame of the first rock splitter rotary drive system 51 by bolts. The lower part of the inner ring of the second slewing bearing is fixedly connected to the upper part of the first rock splitter cylinder 52. The second drive motor is fixedly mounted on the support frame of the first rock splitter rotary drive system 51. The second drive wheel on the output shaft of the second drive motor meshes with the inner ring teeth of the second slewing bearing. Therefore, the second drive motor can be used to realize the free rotation drive of the first rock splitter 5. The upper part of the support frame of the first rock splitter rotary drive system 51 is connected to the first sliding support 55. Therefore, by using the reciprocating up-and-down sliding and positioning of the first sliding support 55, the first rock splitter 5 can be realized to slide up and down and be positioned on the frame 3.

[0022] Based on the above embodiments, the specific implementation method for the second rock splitter 6 to achieve free rotation, vertical movement, and positioning on the frame 3 is as follows: A second rock splitter rotary drive system 62 and a second lifting mechanism are also provided on the frame 3. The second rock splitter 6 is mounted on the second rock splitter rotary drive system 62, and the second rock splitter rotary drive system 62 can drive the second rock splitter 6 to rotate around its own axis. The second lifting mechanism is mounted on the frame 3, and the second lifting mechanism can drive the second rock splitter rotary drive system 62 and the second rock splitter 6 to move vertically and position as a whole. Specifically, the second lifting mechanism includes a second hydraulic cylinder 61 and a second sliding support seat 63. The second sliding support seat 63 is slidably mounted on the frame 3. The second hydraulic cylinder 61 is mounted on the frame 3, and the extension and retraction end of the second hydraulic cylinder 61 is connected to the second sliding support seat 63. The reciprocating motion of the second hydraulic cylinder 61 enables the second sliding support... The second rock splitter 63 reciprocates up and down; the second rock splitter rotary drive system 62 is mounted on the second sliding support 63. The second rock splitter rotary drive system 62 can be a hydraulic drive rotary system commonly used in the field of existing engineering machinery. It includes a third drive motor and a third slewing bearing. The inner ring of the third slewing bearing is fixedly connected to the support frame of the second rock splitter rotary drive system 62 by bolts. The lower part of the outer ring of the third slewing bearing is fixedly connected to the upper part of the second rock splitter. The third drive motor is fixedly mounted on the support frame of the second rock splitter rotary drive system 62. The third drive wheel mounted on the output shaft of the third drive motor meshes with the outer ring teeth of the third slewing bearing. Therefore, the free rotation drive of the second rock splitter 6 can be achieved by using the third drive motor. The upper part of the support frame of the second rock splitter rotary drive system 62 is connected to the second sliding support 63. Therefore, by using the reciprocating up and down sliding and positioning of the second sliding support 63, the up and down sliding and positioning of the second rock splitter 6 on the frame 3 can be achieved.

[0023] This utility model also provides a drilling and splitting integrated machine, including the double splitting mechanism described in the above embodiment. The drilling and splitting integrated machine also includes a drilling machine 4, which is a commonly used rock drilling device known in existing drilling and splitting integrated machines. Therefore, the specific working principle of the drilling machine 4 will not be described in detail here. The drilling machine 4 is mounted on the frame 3 and is distributed at intervals with the first splitting machine 5 and the second splitting machine 6. The central axis of the drilling machine 4 is on the same circumference 101 as the central axes of the first splitting machine 5 and the second splitting machine 6. Utilizing the above spatial distribution relationship of the drilling machine 4, the first splitting machine 5, and the second splitting machine 6, the rotation of the frame 3 can be used to achieve precise and rapid adjustment of the three relative to the working position, thereby effectively improving work efficiency and positioning accuracy. The drilling machine 4 can move up and down and be positioned on the frame 3. The vertical movement capability of the drilling machine 4 on the frame 3 facilitates the control of the drilling depth.

[0024] Based on the above embodiments, the specific implementation method for the drilling machine 4 to achieve up-and-down reciprocating movement and positioning on the frame 3 is as follows: a third lifting mechanism is provided on the frame 3. The third lifting mechanism can realize the up-and-down movement and positioning of the drilling machine 4. The third lifting mechanism includes a third hydraulic cylinder 43, a middle guide sprocket group, an upper guide sprocket 432, a lower guide sprocket 433, an upper transmission chain, a lower transmission chain, and a third sliding support 45. The third sliding support 45 is slidably mounted on the frame 3, and the third hydraulic cylinder 43 is vertically mounted on the frame 3. The base of the upper third hydraulic cylinder 43 is connected to the frame 3. The middle guide sprocket assembly includes a fixed frame 431, an upper middle guide sprocket 4311, and a lower middle guide sprocket 4312. The fixed frame 431 is fixedly mounted on the telescopic end of the third hydraulic cylinder 43. The upper middle guide sprocket 4311 and the lower middle guide sprocket 4312 are rotatably mounted on the fixed frame 431. The upper guide sprocket 432 is rotatably mounted on the upper part of the frame 3, and the lower guide sprocket 431 is rotatably mounted on the lower part of the frame 3. One end of the upper transmission chain is connected to the third sliding... The moving support 45 is fixedly connected. The other end of the upper transmission chain passes sequentially around the upper guide sprocket 432 and the upper-middle guide sprocket 4311 and is fixedly mounted near the upper guide sprocket 432. One end of the lower transmission chain is fixedly mounted on the frame 3 and adjacent to the cylinder of the third hydraulic cylinder 43. The other end of the lower transmission chain passes sequentially around the lower-middle guide sprocket 4312 and the lower guide sprocket 433 and is fixedly connected to the third sliding support 45. The drilling machine 4 is mounted on the third sliding support 45. Specifically, the drilling motion of the drilling machine 4... The power head 41 is fixedly mounted on the third sliding support 45. The output end of the power head 41 of the drilling machine is connected to the drill rod 42, and the front end of the drill rod 42 is connected to the drill bit 44. In actual application, when the extension end of the third hydraulic cylinder 43 moves upward continuously, the transmission action of the lower transmission chain causes the third sliding support 45 to move downward continuously, thereby realizing the downward movement of the drilling machine 4 and enabling the drilling machine 4 to continuously drill holes. When the extension end of the third hydraulic cylinder 43 moves downward continuously, the transmission action of the upper transmission chain causes the third sliding support 45 to move upward continuously, thereby resetting the drilling machine 4.

[0025] Based on the above embodiments, in order to facilitate the stable positioning of the frame 3 during the entire operation, a positioning shaft 7 is provided at the bottom of the frame 3, and the central axis of the positioning shaft 7 is coaxial with the central axis of the rotary system 2.

[0026] In practical application, the operation process of using the above-mentioned integrated drilling and splitting machine to perform rock drilling and splitting operations is as follows: The first splitting machine 5 is placed in the designated working area and positioned using the positioning shaft 7. The rotary system 2 is activated, and the rotary motor 21 drives the rotary bearing 22 to rotate, thereby rotating the frame 3. The drill bit 44 of the drilling machine is placed at the desired drilling position. At this time, the power head 41 of the drilling machine is activated, and the drill bit 44 is driven by the drill rod 42 to perform drilling. After drilling is completed, the drilling machine 4 is lifted. After the drilling machine is lifted into position, the rotary system 2 is activated again, driving the frame 3 to rotate. The center of the splitting block 54 at the bottom of the first splitting machine 5 is aligned vertically with the center of the drilled hole. The rotary drive system 51 of the first splitting machine is activated, and a suitable rock splitting direction is selected according to the rock. After the rock splitting direction is selected, the first hydraulic cylinder 53 is activated, causing the first splitting... Machine 5 moves downwards within the borehole. Once in position, it begins splitting. At this point, the first splitter's hydraulic cylinder 52 pushes the splitting block 54 to split the rock. After splitting, cracks appear in the rock. The first splitter 5 is then lifted back to its initial position, and the rotary system 2 restarts, driving the frame 3 to rotate. The center of the second splitter 6 is aligned vertically with the center of the drilled borehole. Based on the direction of the rock cracks, the rotary drive system 62 of the second splitter is activated, ensuring that the splitting direction of the second splitter 6 matches the previously formed crack direction. The second hydraulic cylinder 61 is then activated. After the second splitter 6 reaches the splitting position, it begins splitting the rock. The large stroke of the second splitter 6 further expands the existing rock cracks. After splitting, the second splitter 6 is lifted back to its initial position. Through these steps, a double splitting operation can be completed. Compared to existing single-splitting equipment, this integrated drilling and splitting machine can significantly enlarge existing rock cracks and is easy to operate, requiring no additional adjustments to the frame 3.

[0027] In this utility model, "left" and "right" are relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.
