Description

Technical Field

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

[0002] Wheeled twin-head rock drilling equipment is mainly used for tunnel excavation in infrastructure construction projects such as railways, highways, water conservancy and hydropower, as well as roadway excavation in mine development. It can carry out full-section, multi-step synchronous excavation operations, and can also meet various rock drilling operation needs such as system anchors, locking foot anchors, advance small guide tubes, grouting holes, etc.

[0003] When drilling holes in tunnels, existing drilling rigs need to first move to the bottom of the rock wall at the end of the tunnel to perform fixed-point drilling. During this process, the drilling rig moves towards the rock wall, and the mechanical arm on the drilling rig can only move within a certain range. The dual heads increase the movable range, but still cannot cover the entire rock wall. Therefore, the drilling rig needs to be transferred in the horizontal direction of the tunnel. The transfer method adopted by existing drilling rigs is mostly to move the equipment back and forth obliquely through moving wheels or tracks to transfer the entire equipment to a horizontal position that can cover another range of the rock wall. The operation is cumbersome and requires a lot of energy and time.

[0004] Patent document with publication number CN119333046A discloses a rock drilling rig support assembly and hydraulic control system, wherein the support assembly includes a vehicle body, a cab, a crawler walking device, a support device and a mechanical arm, wherein an operating platform is rotatably provided on the mechanical arm, the operating platform is provided at the end of the mechanical arm, the support device is provided on the front and rear sides of the vehicle body, the support device includes a connecting device and a supporting hydraulic cylinder, the connecting device is provided on the vehicle body, and the supporting hydraulic cylinder is provided on both sides of the connecting device.

[0005] The supporting structure mainly consists of a crawler walking device and a supporting device. The crawler walking device provides mobile support for the equipment, while the supporting device can only provide static support for the equipment. When the moving direction faces the rock wall, it still needs to move back and forth obliquely to adjust the lateral position of the vehicle body, which is time-consuming and labor-intensive and also increases energy consumption.

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

DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, 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.

[0036] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 and Figure 10 As shown, an embodiment of the present invention provides a wheel-type dual-head rock drilling equipment, comprising:

[0037] The vehicle body 1 has a control room 101 installed on the upper side of the vehicle body 1. Two mechanical arms 102 are connected to the ends of the vehicle body 1. The two mechanical arms 102 are equipped with rock drilling mechanisms 103. The control room 101 is installed on the upper side of the vehicle body 1 to ensure that the operator has a good field of vision. The two mechanical arms 102 are then connected to the front end of the vehicle body 1 and the other end is connected to the rear end of the vehicle body 1. The rock drilling mechanism 103 is installed on the mechanical arms 102. The rock drilling mechanism 103 is a key component for completing rock drilling operations and can drill holes in rock walls.

[0038] The supporting device 2 includes four hydraulic jacks 201 fixedly connected to both sides of the vehicle body 1, and 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 rig, which is connected to the engine. The moving wheel 202 can be driven by the engine to rotate, 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 and facilitate rock drilling operations. 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 jacking operation of the vehicle body 1, and the four hydraulic jacks 201 work synchronously;

[0039] 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 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 track 302 moves downward to the maximum distance, the moving wheel 202 will be in a suspended state. At this time, the supporting track 302 serves as the mobile support component of the equipment to support the entire vehicle body 1. Then, the moving wheel 202 and the supporting track 302 are connected by the docking linkage 4, so that the two are connected together by transmission. The moving wheel 202 is driven by the engine to rotate, and then the docking linkage 4 is used to drive the supporting track 302 to rotate accordingly. At this time, the moving wheel 202 is in a suspended state and is not subjected to force, while the supporting track 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;

[0040] 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 adjacent hydraulic push rods 201 in the left and right directions. When the hydraulic push rod 201 is telescopically moved, the push head 501 will also move up and down accordingly. The telescopic frames 502 are installed at the front and back ends of the lifting frame 301, and are arranged opposite to the two push heads 501.

[0041] The operating state of the entire device is as follows: when the equipment needs to drill a hole in the rock wall of the tunnel, the vehicle body 1 is first transferred to the vicinity of the rock wall to be drilled by the moving wheels 202. At this time, the support device 2 and the transverse movement mechanism 3 are both in the retracted state. After reaching the designated position, the four hydraulic jacks 201 are extended to lift the entire vehicle body 1 and lift the moving wheels 202 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 convenient for drilling operations. 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 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 jack 201, and the hydraulic jack 201 moves down again, which 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. The supporting crawler 302 and the moving wheel 202 are then connected together through the docking linkage 4, so that the moving wheel 202 can drive the supporting crawler 302 to rotate, thereby realizing direct left and right movement of the vehicle body 1, without the need for the vehicle body 1 to make reciprocating adjustments in the front and back directions, reducing the moving distance, and allowing the mechanical arm 102 and the rock drilling mechanism 103 to quickly start working. There is no need to adjust the relative angle between the vehicle body 1 and the rock wall again, which improves the transfer efficiency while reducing the energy consumption of transferring the vehicle body 1, saving energy.

[0042] like Figure 3As shown in the figure, the specific structure of the piston rod 2012 in the hydraulic push rod 201 of the present invention is disclosed. The hydraulic push rod 201 includes a cylinder body 2011 fixedly connected to both sides of the vehicle body 1. The cylinder body 2011 is an existing hydraulic cylinder barrel, which is connected to the hydraulic system to realize the function of liquid in and out. The piston rod 2012 is slidably installed in the cylinder body 2011, and the push head 501 is connected to the piston rod 2012. The bottom end of the piston rod 2012 is constructed with a mounting groove 2013. The mounting groove 2013 A support rod 2014 is inserted vertically and slidably inside the support rod 2014. The bottom end of the support rod 2014 is fixedly connected to an auxiliary wheel 2015 that is slidably installed in the installation groove 2013. A support spring 2016 that is 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 the auxiliary wheel 2015 is pushed by the elastic force of the support spring 2016 and is located outside the installation groove 2013. The elastic force of the support spring 2016 is much smaller than the gravity of the vehicle body 1. When the support track 302 is in contact with the ground, the auxiliary wheel 2015 is pressed into the inner part of the mounting groove 2013, so that the piston rod 2012 still serves as the main supporting force when supporting the ground, and the auxiliary wheel 2015 does not affect its supporting effect. When the equipment needs to move laterally, the telescopic frame 502 can be sleeved on the pushing head 501 on the piston rod 2012, so that the lifting frame 301 is lowered together with the piston rod 2012 until the support track 302 touches the ground. At this time, the auxiliary wheel 2015 will synchronously touch the ground until the moving wheel 202 is suspended. At this time, the auxiliary wheel 2015 still touches 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 supporting component, providing a good supporting and balancing effect for the vehicle body 1. At the same time, the auxiliary wheel 2015 will not affect the movement of the support track 302, so that the support track 302 can move more smoothly and safely.

[0043] like Figure 4-Figure 5As shown in the figure, the specific structure of the lifting frame 301 and the supporting crawler 302 of the present invention is disclosed. The lifting frame 301 includes a longitudinal frame 3011, and a transverse frame 3012 is constructed at both ends of the longitudinal frame 3011. There are two storage slots 104 and they are used to slide with the two transverse frames 3012. A limiter 6 for clamping the transverse frame 3012 is installed in the storage slot 104. The supporting crawler 302 includes a shaft 3021 that is rotatably installed between the two transverse frames 3012. Both ends of the shaft 3021 are fixedly connected to a rolling wheel 3022 located in the transverse frame 3012. Two adjacent rolling wheels 3022 are sleeved. There are anti-skid tracks 3023, the longitudinal frame 3011 and the two transverse frames 3012 are combined into an I-shaped structure, and the storage groove 104 slides with the two transverse frames 3012 to limit the entire lifting frame 301 so that it can only move up and down to achieve a guiding effect. The rolling wheels 3022 are set in the transverse frames 3012, which can concentrate the pressure in the transverse frames 3012 and the storage grooves 104, making the supporting structure more stable. The anti-skid tracks 3023 are sleeved between the two rolling wheels 3022 to increase the contact area with the ground, thereby improving the grip and facilitating the smooth transfer of the equipment.

[0044] like Figure 4-Figure 5 As shown, the limiting mechanism of the transverse frame 3012 of the present invention is disclosed to prevent the transverse frame 3012 from separating from the storage slot 104, thereby increasing safety. The top edge of the transverse frame 3012 and the bottom edge of the storage slot 104 are constructed with baffles 105 arranged opposite to each other up and down, and a rectangular clamping hole 30121 is constructed on the top of the transverse frame 3012. The limiting member 6 includes a T-shaped rod 601 rotatably mounted on the top of the two storage slots 104, and the upper end of the T-shaped rod 601 is fixedly connected to a flip rod 602. A transmission rod 603 that is movable and passes through the two storage slots 104 is hinged between the two flip rods 602, and a rotating motor 604 is connected to the upper end of one of the T-shaped rods 601. It should be noted that the transverse frame 3012 and the storage slot 104 are in a close sliding relationship. When not affected by external forces, they are only affected by lifting forces. Under the influence of gravity of the lowering frame 301, the horizontal frame 3012 will slowly slide down or not slide down in the storage slot 104. It will only slide down smoothly when pushed by the hydraulic push rod 201. After the equipment completes the transfer of the horizontal position, the hydraulic push rod 201 will drive the telescopic frame 502 and the lifting frame 301 to move up together, so that the horizontal frame 3012 is reset to the storage slot 104. At this time, the T-shaped rod 601 will be inserted into the rectangular clamping hole 30121, and then the T-shaped rod 601 can be driven to rotate by rotating the motor 604 to achieve the clamping of the rectangular clamping hole 30121. At the same time, through the hinged connection of the flip 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.

[0045] like 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 of the longitudinal frame 3011 and sleeved on the two shafts 3021. The two shafts 3021 are fixedly sleeved with a transmission bevel gear 402 located in the intermediate frame 401. A transmission bevel gear 402 located in the intermediate frame 401 is rotatably installed in the intermediate frame 401. 021 direction vertically arranged linkage shaft 403, both ends of the linkage shaft 403 are fixedly connected with the driving bevel gear 404 meshing with the transmission bevel gear 402, the longitudinal frame 3011 is rotatably installed with the auxiliary shaft 405 arranged parallel to the linkage shaft 403, the auxiliary shaft 405 and the linkage shaft 403 are connected through a sprocket and a chain transmission, the longitudinal frame 3011 is rotatably installed with a telescopic shaft 407 arranged opposite to the auxiliary shaft 405, the movable end of the telescopic shaft 407 is used to mesh with the end of the auxiliary shaft 405, and the fixed end of the telescopic shaft 407 is connected to the moving wheel 202 by 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 is lowered, the tensioning connecting piece 406 can still realize stable transmission between the two. When the equipment 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 is not engaged with the auxiliary shaft 405, that is, the moving wheel 202 only rotates by itself. When the equipment 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 the auxiliary shaft 405. The shaft 405 is engaged, 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 engagement of the driving bevel gear 404 and the transmission bevel gear 402, so as to realize the rotation of the support track 302, so as to drive the equipment to move horizontally, without the need for additional driving force, and use the driving force of the vehicle body 1 itself to transmit to the support track 302 through the moving wheel 202 for use, thereby increasing the linkage effect.

[0046] like Figure 6As shown, the specific structure of the tensioning connector 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 tensioning connector 406 includes a spring telescopic rod 4061 fixedly connected to the longitudinal frame 3011 and located between the telescopic shaft 407 and the moving wheel 202. The movable end of the spring telescopic rod 4061 and the moving wheel 202 and the telescopic shaft 407 are all equipped with synchronous wheels 4062. 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, the synchronous belt 4063 is a chain structure, and the spring telescopic rod 4061 includes a fixed sprocket structure fixedly connected to the longitudinal frame 3011. The fixed block is connected to a vertical cylinder, and an inner rod is slidably inserted in 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 in the U-shaped seat. The spring telescopic rod 4061 can make the synchronous wheel 4062 always contact the synchronous drive 4063. In the initial state, the synchronous belt 4063 is arranged in a triangle. When the lifting frame 301 descends, the distance between the telescopic shaft 407 and the moving wheel 202 will increase, thereby causing the synchronous belt 4063 to contract. At this time, the deformation of the synchronous belt 4063 can be adapted by the contraction of the spring telescopic rod 4061, thereby ensuring smooth transmission.

[0047] like Figure 6 As 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 slides through the horizontal frame 3012 and is inserted into the vertical frame 3011. The opposite ends of the two U-shaped frames 5021 are sealed ends and are hinged with connecting rods 5022. 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 symmetrical structures and are equilateral V-shaped as a whole. In the initial state, the U-shaped frame 5021 is in a retracted state. At this time, the U-shaped frame 5021 and the push head 501 are separated. , will not affect the telescopic operation of the hydraulic push rod 201. When the mutually hinged ends of the two connecting rods 5022 are pushed, the two U-shaped frames 5021 will be driven to slide in the horizontal frame 3012 and the vertical frame 3011, thereby gradually extending so that the U-shaped frame 5021 is wrapped around the pushing head 501. When the hydraulic push rod 201 moves, the U-shaped frame 5021 will be driven to move together, thereby realizing the lifting function of the lifting frame 301. No additional driving force is required, and the lifting frame 301 can be driven to move by using the original hydraulic push rod 201.

[0048] like Figure 7-Figure 8As shown in the figure, the specific structure of the telescopic shaft 407 of the present invention is disclosed, which facilitates the switching of transmission connection and disconnection operations.
