Description

Technical Field

[0001] The present invention relates to the technical field of rock drilling equipment, and particularly relates to a wheeled double-head rock drilling equipment. Background Art

[0002] The wheeled double-head rock drilling equipment is mainly used for tunnel excavation in infrastructure construction projects such as railways, highways, water conservancy and hydropower, and roadway tunneling in mine development, etc. It can carry out full-section and multi-step synchronous excavation operations, and can also meet the requirements of various rock drilling operations such as system bolts, foot-locking bolts, advanced small ducts, and grouting holes.

[0003] When the existing rock drilling jumbo is performing tunnel drilling work, it needs to first move under the rock wall at the end of the tunnel for fixed-point drilling. During this process, the moving direction of the rock drilling jumbo faces the rock wall, and the robotic arm on the rock drilling jumbo can only move within a certain range. The double heads increase the movable range to some extent, but still cannot cover the entire rock wall. Therefore, it is necessary to transfer the rock drilling jumbo in the transverse direction of the tunnel. The existing transfer methods adopted by the rock drilling jumbo mostly involve moving the wheels or tracks in a reciprocating diagonal movement back and forth to transfer the entire equipment to the transverse position that can cover another range of the rock wall. The operation is cumbersome and requires a large amount of energy and time.

[0004] The patent document with the publication number CN119333046A discloses a support assembly and a hydraulic control system for a rock drilling jumbo. The support assembly includes a vehicle body, a cab, a crawler walking device, a support device and a robotic arm. An operating platform is rotatably arranged on the robotic arm, and the operating platform is arranged at the end of the robotic arm. The support device is arranged on both the front and rear sides of the vehicle body. The support device includes a connecting device and a support hydraulic cylinder. The connecting device is arranged on the vehicle body, and the support hydraulic cylinder is arranged on both sides of the connecting device.

[0005] The main support structures among them are the crawler walking device and the support device. The crawler walking device provides mobile support for the equipment, while the support device can only provide static support for the equipment. When the moving direction faces the rock wall, it is still necessary to move back and forth diagonally to adjust the transverse position of the vehicle body, which is time-consuming and laborious and also increases energy consumption.

[0006] Therefore, the present invention proposes a wheeled double-head rock drilling equipment. Summary of the Invention

Detailed Embodiment

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 and Figure 10 shown, a wheeled double-head rock drilling device proposed in an embodiment of the present invention includes: A vehicle body 1, on the upper side of which a control room 101 is installed, and at the end of the vehicle body 1, two robotic arms 102 are connected. On the two robotic arms 102, a rock drilling mechanism 103 is installed. The control room 101 is installed on the upper side of the vehicle body 1 to ensure that the operator has a good view. Then, the two robotic arms 102 are connected to the front end of the vehicle body 1, and the other end is the rear end of the vehicle body 1. The rock drilling mechanism 103 is installed on the robotic arm 102. The rock drilling mechanism 103 is a key component existing for completing rock drilling operations and can drill holes in the rock wall; The supporting device 2 includes four hydraulic jacks 201 fixedly connected to both sides of the vehicle body 1. A moving wheel 202 is rotatably installed at the bottom of the vehicle body 1. The moving wheel 202 adopts the wheel hub component on the existing rock drilling trolley, which is connected to the engine. The moving wheel 202 can be driven to rotate by the engine, thereby driving the vehicle body 1 to move. The fixed end of the hydraulic jack 201 is connected to the vehicle body 1, and the movable end is arranged toward the ground. When the movable end of the hydraulic jack 201 is extended, the vehicle body 1 can be lifted upward as a whole until the moving wheel 202 is suspended in the air. At this time, the hydraulic jack 201 is used as a static supporting component, which can make the equipment more stably supported on the ground, so as to facilitate the rock drilling operation. It should be noted that a hydraulic system connected to the hydraulic jack 201 is installed on the vehicle body 1, which is used to provide driving force for the four hydraulic jacks 201, so as to realize the lifting operation of the vehicle body 1, and the four hydraulic jacks 201 work synchronously; The transverse movement mechanism 3 has a storage groove 104 at the bottom of the vehicle body 1. The transverse movement mechanism 3 includes a lifting frame 301 that is vertically slidably installed in the storage groove 104. Two supporting tracks 302 that are arranged perpendicular to the moving direction of the moving wheel 202 are installed in the lifting frame 301. A docking linkage 4 for drivingly connecting the supporting tracks 302 and the moving wheel 202 is installed on the lifting frame 301. It should be noted that the lifting frame 301 is slidably arranged in the storage groove 104. At the same time, the storage groove 104 limits the moving distance of the lifting frame 301 so that it can only slide in the storage groove 104. When the storage groove 104 moves downward to the maximum distance, the bottom end of the supporting track 302 is lower than The moving wheel 202 is at the bottom, so when the supporting crawler 302 moves downward to the maximum distance, the moving wheel 202 will be in a suspended state. At this time, the supporting crawler 302 serves as the moving support component of the equipment to support the entire vehicle body 1, and then the moving wheel 202 and the supporting crawler 302 are connected by the docking linkage 4, so that the two are connected together by transmission, and the moving wheel 202 is driven by the engine to rotate, and then the supporting crawler 302 is driven by the docking linkage 4 to rotate accordingly. At this time, the moving wheel 202 is in a suspended state and is not subjected to force, while the supporting crawler 302 is in contact with the ground and bears the weight of the entire vehicle body 1, which can effectively provide grip and realize the lateral transfer of the vehicle body 1; The lifting mechanism 5 includes a push head 501 installed at the movable end of the hydraulic push rod 201. Telescopic frames 502 for extending and wrapping the push head 501 are installed at both ends of the lifting frame 301. It should be noted that there are four hydraulic push rods 201 and they are distributed in a rectangular shape at the four corners of the vehicle body 1. The length direction of the vehicle body 1 is the front-to-back direction, and the width direction is the left-to-right direction. A push head 501 is connected between two hydraulic push rods 201 adjacent to each other in the left-to-right direction. When the hydraulic push rod 201 is telescopically moved, the push head 501 will also be lifted and moved accordingly. The telescopic frames 502 are installed at the front-to-back ends of the lifting frame 301 and are arranged opposite to the two push heads 501. The operation status of the whole device is as follows: when the equipment needs to drill a hole in the rock wall in the tunnel, the vehicle body 1 is first transferred to the vicinity of the rock wall where the hole needs to be drilled by the moving wheel 202. At this time, the support device 2 and the lateral movement mechanism 3 are both in the retracted state. After reaching the designated position, the four hydraulic jacks 201 are extended to lift the whole vehicle body 1, so that the moving wheels 202 are off the ground. At this time, the hydraulic jacks 201 serve as the supporting components of the equipment, so that the equipment is placed stably and the drilling operation is convenient. When the rock wall in front of the vehicle body 1 is drilled by the two mechanical arms 102 and the rock drilling mechanism 103, and it can no longer reach a farther range, the hydraulic jacks 201 can be retracted, and the moving wheels 202 support the ground again. At this time, the telescopic frame 50 in the lifting frame 301 is 2 extends outward until it is wrapped around the pushing head 501 on the hydraulic push rod 201, and the hydraulic push rod 201 moves down again, at this time it will drive the lifting frame 301 to move down synchronously until the supporting crawler 302 touches the ground, and the moving wheel 202 is suspended again, and then the supporting crawler 302 and the moving wheel 202 are connected together by the docking linkage 4, so that the moving wheel 202 can drive the supporting crawler 302 to rotate, thereby realizing the direct left-right movement of the vehicle body 1, without the need for the vehicle body 1 to reciprocate forward and backward, reducing the moving distance, allowing the mechanical arm 102 and the rock drilling mechanism 103 to quickly work, without the need to adjust the relative angle between the vehicle body 1 and the rock wall again, improving the transfer efficiency while reducing the energy consumption of transferring the vehicle body 1, saving energy.

[0022] like Figure 3As shown, the specific structure of the piston rod 2012 in the hydraulic jack 201 of the present invention is disclosed. The hydraulic jack 201 includes cylinder bodies 2011 fixedly connected to both sides of the vehicle body 1. The cylinder bodies 2011 are existing hydraulic cylinder barrels, which are connected to a hydraulic system to realize the function of liquid inlet and outlet. A piston rod 2012 is slidably installed in the cylinder body 2011. A push head 501 is connected to the piston rod 2012. An installation groove 2013 is formed at the bottom end of the piston rod 2012. A support rod 2014 is vertically slidably inserted into the installation groove 2013. The bottom end of the support rod 2014 is fixedly connected to an auxiliary wheel 2015 slidably installed in the installation groove 2013. A support spring 2016 sleeved on the support rod 2014 is connected between the auxiliary wheel 2015 and the inner end of the installation groove 2013. It should be noted that under the elastic force of the support spring 2016, the auxiliary wheel 2015 is outside the installation groove 2013, and the elastic force of the support spring 2016 is much smaller than the gravity of the vehicle body 1. When the piston rod 2012 moves downward and gradually touches the ground, the auxiliary wheel 2015 will be gradually pressed into the interior of the installation groove 2013. Therefore, when the piston rod 2012 supports the ground, it still serves as the main supporting force, and the auxiliary wheel 2015 will not affect its supporting effect. When the device needs to move horizontally, the push head 501 on the piston rod 2012 can be sleeved by the telescopic frame 502, so that the lifting frame 301 descends together with the piston rod 2012 until the supporting track 302 touches the ground. At this time, the auxiliary wheel 2015 will also touch the ground synchronously until the moving wheel 202 is suspended. At this time, the auxiliary wheel 2015 will still touch the ground, but the bottom end of the piston rod 2012 is in a suspended state. The auxiliary wheel 2015 can be used as an auxiliary support component to provide a good support balance effect for the vehicle body 1. At the same time, the auxiliary wheel 2015 will not affect the movement of the supporting track 302, enabling the supporting track 302 to move more smoothly and safely.

[0023] As Figures 4 - 5As shown in the figure, the specific structures of the lifting frame 301 and the supporting crawler 302 of the present invention are disclosed. The lifting frame 301 includes a longitudinal frame 3011, and transverse frames 3012 are constructed at both ends of the longitudinal frame 3011. The number of storage slots 104 is two and they are used for sliding cooperation with the two transverse frames 3012. A limiting member 6 for clamping the transverse frame 3012 is installed in the storage slot 104. The supporting crawler 302 includes a shaft rod 3021 rotatably and penetratingly installed between the two transverse frames 3012. Rolling wheels 3022 located within the transverse frames 3012 are fixedly connected to both ends of the shaft rod 3021. An anti-slip crawler 3023 is sleeved between two adjacent rolling wheels 3022. The longitudinal frame 3011 and the two transverse frames 3012 are combined into an I-shaped structure. The storage slot 104 is in sliding cooperation with the two transverse frames 3012 to limit the entire lifting frame 301 so that it can only move up and down, achieving a guiding effect. By arranging the rolling wheels 3022 within the transverse frames 3012, the pressure can be concentrated within the transverse frames 3012 and the storage slots 104, making the supporting structure more stable. And by sleeving the anti-slip crawler 3023 between the two rolling wheels 3022, the contact area with the ground can be increased, thereby improving the grip and facilitating the smooth transfer of the equipment.

[0024] As Figures 4 - 5 shown in the figure, the limiting mechanism of the transverse frame 3012 of the present invention is disclosed to prevent the transverse frame 3012 from disengaging from the storage slot 104 and increase safety. Baffles 105 are constructed at the top edge of the transverse frame 3012 and the bottom edge of the storage slot 104 and are arranged opposite to each other vertically. A rectangular clamping hole 30121 is constructed at the top of the transverse frame 3012. The limiting member 6 includes a T-shaped rod 601 rotatably installed at the top inside the two storage slots 104. A turning rod 602 is fixedly connected to the upper end of the T-shaped rod 601. A transmission rod 603 that movably penetrates the two storage slots 104 is hinged between the two turning rods 602. A turning motor 604 is connected to the upper end of one of the T-shaped rods 601. It should be noted that there is a tight sliding relationship between the transverse frame 3012 and the storage slot 104. Without being affected by external forces, and only affected by the gravity of the lifting frame 301, the transverse frame 3012 will slowly slide down or not slide down within the storage slot 104. Only when pushed by the hydraulic jack 201 will it slide down smoothly. After the equipment completes the lateral position transfer, the hydraulic jack 201 will drive the telescopic frame 502 and the lifting frame 301 to move up together, causing the transverse frame 3012 to reset into the storage slot 104. At this time, the T-shaped rod 601 will be inserted into the rectangular clamping hole 30121, and then the turning motor 604 can drive the T-shaped rod 601 to rotate to achieve the clamping of the rectangular clamping hole 30121. At the same time, through the hinge of the turning rod 602 and the transmission rod 603, the other T-shaped rod 601 can be driven to rotate together to achieve the synchronous clamping of the two rectangular clamping holes 30121, thereby completing the storage operation of the lifting frame 301.

[0025] As Figure 6As shown, the transmission relationship between the support crawler 302 and the moving wheel 202 of the present invention is disclosed, which ensures that the two moving wheels 202 can drive the support crawler 302 to rotate together, or can not drive the support crawler 302 to rotate, and only rotate themselves, which is convenient to switch and realize the linkage effect of the driving force. The docking linkage member 4 includes an intermediate frame 401 fixedly connected to the middle part of the longitudinal frame 3011 and sleeved on the two shaft rods 3021. The two shaft rods 3021 are fixedly sleeved with a transmission bevel gear 402 located in the intermediate frame 401. The intermediate frame 401 is rotatably installed with a transmission bevel gear 402 that is connected to the shaft rod 3021. A linkage shaft 403 is vertically arranged in the 021 direction, and both ends of the linkage shaft 403 are fixedly connected with a driving bevel gear 404 meshing with the transmission bevel gear 402. An auxiliary shaft 405 arranged parallel to the linkage shaft 403 is rotatably installed in the longitudinal frame 3011, and the auxiliary shaft 405 is connected to the linkage shaft 403 through a sprocket and a chain transmission. A telescopic shaft 407 arranged opposite to the auxiliary shaft 405 is rotatably installed in the longitudinal frame 3011, and the movable end of the telescopic shaft 407 is used to mesh with the end of the auxiliary shaft 405. The fixed end of the telescopic shaft 407 is connected to the moving wheel 202 through a tensioning The connecting piece 406 is used for transmission connection. The tensioning connecting piece 406 is mainly used for transmission connection between the telescopic shaft 407 and the moving wheel 202. When the lifting frame 301 descends, the tensioning connecting piece 406 can still realize stable transmission between the two. When the device needs to be transferred forward and backward, only the moving wheel 202 needs to work. At this time, the telescopic shaft 407 is retracted, and the end of the telescopic shaft 407 does not mesh with the auxiliary shaft 405, that is, the moving wheel 202 only rotates by itself. When the device needs to be transferred left and right, the moving wheel 202 is in a suspended state, and the telescopic shaft 407 needs to be extended to mesh with the auxiliary shaft 405. The shaft 405 is meshed, and the rotation of the moving wheel 202 will drive the telescopic shaft 407 and the auxiliary shaft 405 to rotate together through the tensioning connector 406, and then drive the linkage shaft 403 to rotate through the sprocket and chain, and finally drive the shaft rod 3021 to rotate through the meshing of the driving bevel gear 404 and the transmission bevel gear 402, so as to realize the rotation of the supporting crawler 302, so as to drive the equipment to move horizontally, without additional driving force, and use the driving force of the vehicle body 1 itself to transfer to the supporting crawler 302 through the moving wheel 202 for use, thereby increasing the linkage effect.

[0026] like Figure 6As shown, the specific structure of the tension connecting member 406 of the present invention is disclosed, which is used to always maintain the transmission connection between the telescopic shaft 407 and the moving wheel 202. The tension connecting member 406 includes a spring telescopic rod 4061 fixedly connected within the longitudinal frame 3011 and located between the telescopic shaft 407 and the moving wheel 202. Synchronous wheels 4062 are installed on the movable end of the spring telescopic rod 4061, on the moving wheel 202, and on the telescopic shaft 407. A synchronous belt 4063 is sleeved between the three synchronous wheels 4062. It should be noted that the synchronous wheel 4062 is a sprocket structure and the synchronous belt 4063 is a chain structure. The spring telescopic rod 4061 includes a fixed block fixedly connected within the longitudinal frame 3011. A vertical cylinder is connected to the fixed block. An inner rod is slidably inserted into the vertical cylinder. A connecting spring sleeved on the vertical cylinder is connected between the end of the inner rod and the fixed block. A U-shaped seat is constructed at the end of the inner rod. The synchronous wheel 4062 is rotatably installed within the U-shaped seat. The spring telescopic rod 4061 can keep the synchronous wheel 4062 in contact with the synchronous belt 4063 all the time. In the initial state, the synchronous belt 4063 is arranged in a triangular shape. When the lifting frame 301 descends, the distance between the telescopic shaft 407 and the moving wheel 202 will increase, causing the synchronous belt 4063 to contract. At this time, the contraction of the spring telescopic rod 4061 can be used to adapt to the deformation of the synchronous belt 4063, so as to ensure the smooth progress of the transmission.

[0027] As Figure 6 shown, the specific structure of the telescopic frame 502 of the present invention is disclosed. The telescopic frame 502 includes a U-shaped frame 5021 that slidably penetrates the transverse frame 3012 and is inserted into the longitudinal frame 3011. The opposite ends of the two U-shaped frames 5021 are closed ends, and connecting rods 5022 are hinged thereto. The ends of the two connecting rods 5022 are hinged to each other and are arranged in a V shape. The two connecting rods 5022 are symmetric structures and are in an equilateral V shape as a whole. In the initial state, the U-shaped frame 5021 is in a contracted state. At this time, the U-shaped frame 5021 is disengaged from the pushing head 501 and will not affect the telescopic operation of the hydraulic jack 201. When the hinged ends of the two connecting rods 5022 are pushed, the two U-shaped frames 5021 will be driven to slide within the transverse frame 3012 and the longitudinal frame 3011, thereby gradually extending and wrapping the U-shaped frame 5021 around the pushing head 501. When the hydraulic jack 201 moves, it will drive the U-shaped frame 5021 to move together, so as to realize the lifting function of the lifting frame 301 without additional driving force. The original hydraulic jack 201 can be used to drive the lifting frame 301 to move.

[0028] As Figures 7 - 8As shown, the specific structure of the telescopic shaft 407 of the present invention is disclosed, which facilitates the switching of transmission connection and disconnection operations. The telescopic shaft 407 includes a rotating drum 4071 rotatably mounted on one side of the longitudinal frame 3011, and a polygonal column 4072 is slidably mounted in the rotating drum 4071. The polygonal column 4072 is a hexagonal structure. One end of the polygonal column 4072 is connected to a plug-in bevel gear 4073 and the other end is rotatably connected to a push plate 4074. The end of the auxiliary shaft 405 is constructed with a bevel tooth groove 4075 that meshes with the plug-in bevel gear 4073. By pushing The movement of the movable plate 4074 can drive the polygonal column rod 4072 to pass through the rotating drum 4071 and move toward the auxiliary shaft 405 until the plug-in bevel gear 4073 is inserted into the bevel tooth groove 4075, thereby realizing the connection between the auxiliary shaft 405 and the polygonal column rod 4072. At this time, the rotation of the rotating drum 4071 will drive the polygonal column rod 4072 and the auxiliary shaft 405 to rotate together, thereby realizing a linkage effect. When the state needs to be switched, only the polygonal column rod 4072 needs to be pulled out of the auxiliary shaft 405, and the operation is quick and convenient.

The driving member 7 includes a hydraulic push rod 701 fixedly connected to the bottom of the vehicle body 1, and the output shaft end of the hydraulic push rod 701 is connected to the push plate 4074. The middle part of the output shaft of the hydraulic push rod 701 is constructed with a hinge shaft 702 hinged to the ends of two connecting rods 5022. The hydraulic push rod 701 can synchronously push the two connecting rods 5022 to flip, thereby driving the U-shaped frame 5021 to extend outward, and at the same time, it will also drive the push plate 4074 to move toward the auxiliary shaft 405, so that the telescopic shaft 407 and the telescopic frame 502 can operate synchronously, realize rapid state switching, and ensure that when the equipment switches to lateral movement, the support crawler 302 can be synchronously connected to the moving wheel 202.

[0030] like Figure 9As shown, the specific structure of the driving head 501 of the present invention is disclosed, and a mobile buffer structure is provided to ensure the stability of lateral movement. The driving head 501 includes an n-shaped plate 5011 fixedly connected between two piston rods 2012. A spring shock absorber 5012 for socketing with a U-shaped frame 5021 is installed through the middle of the n-shaped plate 5011. The spring shock absorber 5012 specifically includes a sleeve installed through the n-shaped plate 5011. A piston block is slidably installed in the sleeve. Connecting rods penetrating the sleeve are fixedly connected to both ends of the piston block. A high-strength spring is connected between the end of the connecting rod and the sleeve. The strength of this spring is sufficient to support the weight of the vehicle body 1. The length of the piston block spring shock absorber 5012 is less than the opening height of the U-shaped frame 5021. By installing the spring shock absorber 5012 on the n-shaped plate 5011 and socketing it with the U-shaped frame 5021, while the hydraulic jack 201 can be used to push the lifting frame 301, an elastic buffer component can be provided, enabling the lifting frame 301 to generate a small amount of up and down movement buffer when the supporting track 302 contacts the ground, so that the equipment can move more smoothly laterally and increase the safety of the device.
