Description

Technical Field

[0001] This invention relates to the field of rock drilling equipment technology, and more specifically, to a rock drilling rig based on dual-arm operation. Background Technology

[0002] In mining, tunnel excavation, and other engineering operations, rock drilling rigs, as key drilling equipment, play a crucial role in improving construction efficiency and quality. Among them, rock drilling rigs based on dual-arm operation have a significant advantage in improving work efficiency due to their ability to perform multiple drilling operations simultaneously, and are widely used in various engineering scenarios.

[0003] Existing rock drilling rigs based on dual-arm operation have some problems in actual use. Due to their structural design, the overall upper part of the equipment is relatively high. When moving and adjusting, this high upper structure makes the center of gravity of the equipment relatively high, which is prone to swaying. This swaying not only threatens the stability of the equipment itself and increases the risk of equipment damage, but may also affect the safety of operators. For example, when moving on uneven construction sites, the rig's swaying may cause it to lose balance or even tip over.

[0004] During rock drilling operations, the drilling tool needs to be pressed against the rock wall to perform drilling operations. At this time, relying solely on the self-locking capability of the drive boom is insufficient to completely eliminate the swaying generated at the front end. This is because the rock drilling process generates significant impact and reaction forces. These forces act on the drilling tool and the drive boom, posing a significant challenge to the self-locking mechanism of the drive boom. The swaying at the front end directly affects the accuracy of rock drilling, causing deviations in the position, depth, and angle of the drill hole. This not only affects the construction quality of subsequent projects, such as causing uneven tunnel walls in tunnel excavation, increasing the difficulty of lining, but also affects the efficiency and quality of ore mining in mining operations. It may also require additional correction work, thereby increasing construction costs and time.

[0005] In summary, existing dual-arm rock drilling rigs have significant shortcomings in stability and accuracy, which severely restricts their application in engineering construction. Therefore, there is an urgent need for a new type of dual-arm rock drilling rig that can effectively solve the aforementioned swaying and accuracy problems, in order to meet the growing demands of engineering construction, improve construction efficiency and quality, and ensure construction safety. Summary of the Invention

[0006] The purpose of this invention is to provide a rock drilling rig based on dual-arm operation to solve the problems mentioned in the background art.

[0007] A rock drilling rig based on dual-arm operation includes an operating rig. A pair of hydraulic drive components are fixedly installed on the front side of the operating rig. A drive boom is rotatably mounted on the front side of the hydraulic drive components. A swing cylinder is rotatably mounted on the front side of the drive boom. A protective sleeve is rotatably mounted on the front side of the swing cylinder. A pusher is fixedly installed at the upper end of the protective sleeve.

[0008] A fixing component is fixedly installed on the side of the drive boom, a positioning sleeve is fixedly installed on the side of the fixing component, a hydraulic pusher is fixedly installed on one side of the positioning sleeve, and a lifting plate is fixedly installed on the output end of the hydraulic pusher.

[0009] A fixed sleeve is fixedly installed on the side of the swing cylinder. A rotary motor is fixedly installed on the side of the swing cylinder at the middle of the fixed sleeve. A transmission rod is fixedly installed on the output end of the rotary motor. A sealing plate is fixedly installed on the side of the transmission rod. A fastening plate is provided on the side of the sealing plate. Several limiting clips are fixedly installed at equal intervals on the side of the fastening plate. A limiting groove corresponding to the limiting clips is opened on the side of the lifting plate.

[0010] A connector is fixedly installed at the lower end of the thruster, a movable plate is fixedly installed on the front side of the connector, an electric push rod is fixedly installed in the middle of the connector, and a horizontal bar is fixedly installed at the front end of the electric push rod.

[0011] Furthermore, a drive trolley is provided at the rear of the operating trolley, and support frames are provided on the sides of both the operating trolley and the drive trolley. A main control board is provided on the inner side of the operating trolley.

[0012] By adopting the above technical solution, the drive trolley and the operating trolley can be fixed in place by the support frame, which facilitates subsequent construction operations.

[0013] Furthermore, a lifting hydraulic rod is fixedly installed on the upper end of the hydraulic drive component, and the front output end of the lifting hydraulic rod is rotatably connected to the side of the drive arm.

[0014] By adopting the above technical solution, the up-and-down movement of the drive boom can be controlled by the lifting hydraulic rod, and the horizontal rotation of the drive boom can be controlled by the hydraulic drive components, thereby realizing multi-directional and multi-angle movement of the front drill bit for rock drilling.

[0015] Furthermore, an isolation disc is provided on the side of the transmission rod located on the sealing disc, a fine-tuning groove is provided on the outer side of the sealing disc, and the inner cavity of the fixing sleeve is provided with a thread corresponding to the fine-tuning groove.

[0016] By adopting the above technical solution, the rotary motor can control the overall rotation of the sealing disc through the transmission rod. At this time, the fine adjustment groove on the side of the sealing disc will rotate within the range of the corresponding thread, thereby squeezing and fine-tuning the fastening disc.

[0017] Furthermore, the limiting groove on the side of the lifting plate is three groove structures that decrease in height, and the limiting clip on the side of the fastening plate is two stepped vertical components.

[0018] By adopting the above technical solution, the limiting clip can be engaged and locked with any one of the limiting slots. In the fixed state, the limiting clip and the two higher levels of the limiting slot are engaged and limited. When the rotary motor reverses, the limiting clip and the lifting plate quickly separate and release the force, so that the rigid force between the drive boom and the swing cylinder disappears instantly, which facilitates subsequent adjustment and movement.

[0019] Furthermore, a limiting component is fixedly installed on the outer side of the fastening disc, and an annular groove corresponding to the limiting component is opened in the middle of the inner cavity of the fixing sleeve.

[0020] By adopting the above technical solution, the fastening disc can move slightly horizontally within the annular groove opened inside the fixing sleeve, thereby enabling fine adjustment of the fastening disc.

[0021] Furthermore, a rock drill is fixedly installed on the upper middle part of the thruster, a fiber tool is fixedly installed at the output end of the rock drill, a pipe winder is fixedly installed on one side of the thruster, and a drill bit is fixedly installed at the front end of the fiber tool.

[0022] By adopting the above technical solution, a rock drill can be used to drive the drilling tool into the rock strata, where the drilling tool directly contacts the rock strata to perform the rock drilling operation.

[0023] Furthermore, the horizontal bar has movable slots on both sides, and the movable plate has a pair of positioning posts corresponding to the movable slots in the middle.

[0024] By adopting the above technical solution, the movable plate can move left and right in the middle of the horizontal bar through the positioning column. When the electric push rod pulls the horizontal bar, the connecting parts will open to both sides due to the force, and the movable plate will move to both sides. When the electric push rod extends forward, the movable plates on both sides will move closer to the middle of the horizontal bar.

[0025] Furthermore, a static pressure plate is fixedly installed on the front side of the movable plate, and a hard rubber is provided on the front side of the static pressure plate. An auxiliary plate is rotatably provided on the side of the connector away from the electric push rod.

[0026] By adopting the above technical solution, the auxiliary plate can form a balanced force with the electric push rod, so that the expansion and contraction of the moving plate are synchronized. When the moving plates tighten together, their static pressure plate will contact the rock formation and form a balanced force with the upper drill bit and drive arm, thereby maintaining the overall balance of the thruster.

[0027] Compared with the prior art, the advantages of this invention are:

[0028] 1. In this invention, by setting a structure with a positioning sleeve and a fixing sleeve, the upper driving arm and the swing cylinder can be quickly self-locked during the movement of the driving arm, effectively reducing the shaking of the upper pusher.

[0029] 2. In this invention, by setting a structure with horizontal bars, when drilling rock, the structure of the moving plate and the static pressure plate can assist in supporting the rock structure against the rock wall. This structure, together with the structure formed by locking the drive arm, forms a relative shear structure, thereby improving the overall processing stability. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1 - Figure 7 As shown, the embodiment of the present invention provides: including an operating trolley 3, a pair of hydraulic drive components 5 fixedly installed on the front side of the operating trolley 3, a drive arm 7 rotatably arranged on the front side of the hydraulic drive components 5, a swing cylinder 18 rotatably arranged on the front side of the drive arm 7, a protective sleeve 13 rotatably arranged on the front side of the swing cylinder 18, and a pusher 12 fixedly installed on the upper end of the protective sleeve 13.

[0040] A fixing component 14 is fixedly installed on the side of the drive boom 7, a positioning sleeve 15 is fixedly installed on the side of the fixing component 14, a hydraulic pusher 16 is fixedly installed on one side of the positioning sleeve 15, and a lifting plate 21 is fixedly installed at the output end of the hydraulic pusher 16.

[0041] A fixed sleeve 17 is fixedly installed on the side of the swing cylinder 18. A rotary motor 20 is fixedly installed on the side of the swing cylinder 18 at the middle of the fixed sleeve 17. A transmission rod 22 is fixedly installed at the output end of the rotary motor 20. A sealing plate 2002 is fixedly installed on the side of the transmission rod 22. A fastening plate 23 is provided on the side of the sealing plate 2002. Several limit clips 24 are fixedly installed at equal intervals on the side of the fastening plate 23. A limit groove 25 corresponding to the limit clips 24 is opened on the side of the lifting plate 21.

[0042] A connector 26 is fixedly installed at the lower end of the pusher 12, a movable plate 29 is fixedly installed on the front side of the connector 26, an electric push rod 27 is fixedly installed in the middle of the connector 26, and a horizontal rod 19 is fixedly installed at the front end of the electric push rod 27.

[0043] The operating trolley 3 is equipped with a drive trolley 2 at the rear. Both the operating trolley 3 and the drive trolley 2 are equipped with support frames 1 on their sides. The main control board 4 is installed inside the operating trolley 3. The drive trolley 2 and the operating trolley 3 can be fixed in place by the support frames 1 to facilitate subsequent construction operations.

[0044] A lifting hydraulic rod 6 is fixedly installed on the upper end of the hydraulic drive component 5. The front output end of the lifting hydraulic rod 6 is rotatably connected to the side of the drive boom 7. The lifting hydraulic rod 6 can control the up and down movement of the drive boom 7, and the hydraulic drive component 5 can control the horizontal rotation of the drive boom 7, thereby realizing multi-directional and multi-angle rock drilling of the front drill bit 11.

[0045] The transmission rod 22 is located on the side of the sealing disc 2002 and is equipped with an isolation disc 2001. The outer side of the sealing disc 2002 is provided with a fine adjustment groove 2003. The inner cavity of the fixing sleeve 17 is provided with a thread corresponding to the fine adjustment groove 2003. The rotary motor 20 can control the sealing disc 2002 to rotate as a whole through the transmission rod 22. At this time, the fine adjustment groove 2003 on the side of the sealing disc 2002 will rotate within the range of the corresponding thread, so that the fastening disc 23 can be squeezed and finely adjusted.

[0046] The limiting groove 25 on the side of the lifting plate 21 is a three-slotted structure that descends in sequence. The limiting clip 24 on the side of the fastening plate 23 is a two-step vertical component. The limiting clip 24 can engage with any one of the limiting grooves 25 and lock in place. In the fixed state, the limiting clip 24 and the two higher levels of the limiting groove 25 are engaged and limited. When the rotary motor 20 reverses, the limiting clip 24 and the lifting plate 21 quickly separate and release the force, so that the rigid force between the drive boom 7 and the swing cylinder 18 disappears instantly, which facilitates subsequent adjustment and movement.

[0047] A limiting member 2301 is fixedly installed on the outer side of the fastening plate 23. An annular groove corresponding to the limiting member 2301 is opened in the middle of the inner cavity of the fixing sleeve 17. The fastening plate 23 can move slightly horizontally in the annular groove opened inside the fixing sleeve 17, thereby enabling fine adjustment of the fastening plate 23.

[0048] A rock drill 9 is fixedly installed on the upper middle part of the pusher 12. A fiber optic cable 10 is fixedly installed at the output end of the rock drill 9. A pipe winder 8 is fixedly installed on one side of the pusher 12. A drill bit 11 is fixedly installed at the front end of the fiber optic cable 10. The fiber optic cable 10 can be driven into the rock layer by the rock drill 9. The drill bit 11 directly contacts the rock layer to perform rock drilling operation.

[0049] The horizontal bar 19 has movable slots 28 on both sides, and a pair of positioning posts corresponding to the movable slots 28 are provided in the middle of the movable plate 29. The movable plate 29 can move left and right in the middle of the horizontal bar 19 through the positioning posts. When the electric push rod 27 pulls the horizontal bar 19, the connecting piece 26 will open to both sides due to the force, and the movable plate 29 will move to both sides. When the electric push rod 27 extends forward, the movable plates 29 on both sides will move closer to the middle of the horizontal bar 19.

[0050] A static pressure plate 30 is fixedly installed on the front side of the moving plate 29. The front side of the static pressure plate 30 is provided with hard rubber. An auxiliary plate 31 is rotatably provided on the side of the connector 26 away from the electric push rod 27. The auxiliary plate 31 can form a balancing force with the electric push rod 27, so that the expansion and contraction of the moving plate 29 are synchronized. When the moving plates 29 tighten each other, the static pressure plate 30 will contact the rock formation and form a balanced force with the upper drill bit 11 and the drive arm 7, thereby maintaining the overall balance of the thruster 12.

[0051] Working principle of the invention: The driving trolley 2 is set on the rear side of the operating trolley 3. The support frame 1 on the side of the two trolleys is used to fix them in place, providing a stable foundation for subsequent construction operations. The main control board 4 inside the operating trolley 3 is used to centrally control the operation of the entire rock drilling trolley. The operator can issue commands through the main control board 4 to achieve precise control of each component.

[0052] The lifting hydraulic rod 6 at the upper end of the hydraulic drive component 5 has its front output end rotatably connected to the side of the drive boom 7. When it is necessary to adjust the height of the drive boom 7, the main control board 4 controls the extension and retraction of the lifting hydraulic rod 6, thereby driving the drive boom 7 to move up and down. The hydraulic drive component 5 can control the drive boom 7 to rotate horizontally around its connection point with the hydraulic drive component 5. Through the coordinated action of the lifting hydraulic rod 6 and the hydraulic drive component 5, the front drill bit 11 can move in multiple directions and angles to meet the rock drilling needs of different positions and angles.

[0053] A fixing member 14 is provided on the side of the drive boom 7, and a positioning sleeve 15 is fixed on the side of the fixing member 14. The drive boom 7 and the swing cylinder 18 are rotatably connected. A fixing sleeve 17 is provided on the outside of the connection. After the drive boom 7 moves to the designated position, the hydraulic pusher 16 on one side of the positioning sleeve 15 pushes the lifting plate 21, so that the limiting groove 25 on the side of the lifting plate 21 and the limiting clip 24 on the side of the fastening plate 23 are engaged and locked, realizing the rapid self-locking of the drive boom 7 and the swing cylinder 18, effectively reducing the shaking of the upper pusher 12 during operation.

[0054] The rotary motor 20 located in the middle of the side fixing sleeve 17 of the swing cylinder 18 drives the sealing disc 2002 to rotate as a whole via the transmission rod 22 at its output end. The fine-tuning groove 2003 on the outer side of the sealing disc 2002 rotates within the range corresponding to the thread in the inner cavity of the fixing sleeve 17, thereby squeezing and fine-tuning the fastening disc 23. At the same time, the limiting member 2301 on the outer side of the fastening disc 23 moves slightly horizontally within the annular groove in the middle of the inner cavity of the fixing sleeve 17, further achieving fine-tuning of the fastening disc 23. When the sealing disc 2002 rotates, it presses on the fastening disc 23, while simultaneously... The moving fastening plate 23 rotates slightly. At this time, the fastening plate 23 and the lifting plate 21 cooperate to achieve a quick locking of the connection position. The upper side of the drive boom 7 remains stable during the overall rapid adjustment. At the same time, when it rotates to the designated position, the fixed state is that the two stages of the limit card 24 and the limit groove 25 are engaged and limited. When the rotary motor 20 reverses, the limit card 24 and the lifting plate 21 quickly separate and release the force, releasing the rigid state, so that the rigid force between the drive boom 7 and the swing cylinder 18 disappears instantly, which facilitates subsequent adjustment and movement.

[0055] The rock drill 9 at the upper middle of the pusher 12 is started, and the drill bit 11 at the front end of the fiber tool 10 directly contacts the rock layer to drill. The electric push rod 27 in the middle of the lower end connector 26 of the pusher 12 is connected to the horizontal rod 19 at its front end. The moving grooves 28 on both sides of the horizontal rod 19 cooperate with the positioning pin in the middle of the moving plate 29, so that the moving plate 29 can move left and right in the middle of the horizontal rod 19. When the electric push rod 27 pulls the horizontal rod 19, the connector 26 is forced to open to both sides, and the moving plate 29 moves to both sides. When the electric push rod 27 extends forward, the moving plates 29 on both sides move closer to the middle of the horizontal rod 19. The static pressure plate 30 on the front side of the moving plate 29 is provided with hard rubber. When the moving plates 29 tighten together, the static pressure plate 30 contacts the rock layer.

[0056] The auxiliary plate 31, which is rotatably mounted on the side of the connector 26 away from the electric push rod 27, forms a balancing force with the electric push rod 27, keeping the expansion and contraction of the moving plate 29 synchronized. During rock drilling, it locks the fastening plate 23 and the lifting plate 21. The static pressure plate 30 forms a balanced force with the upper drill bit 11 and the drive arm 7, thereby maintaining the overall balance of the pusher 12 during rock drilling and reducing the impact of shaking on the accuracy of rock drilling.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
