Description

Technical Field

[0001] The present invention relates to the technical field of rock drilling equipment, and particularly to a wheeled multi-angle propulsion rock drilling equipment. Background Technique

[0002] Rock drilling equipment is the core equipment for drilling operations. Although the current mainstream rock drilling equipment (such as rock drilling jumbo, rotary drill, etc.) has achieved mechanized operation, there are still significant technical bottlenecks under complex working conditions:

[0003] The propulsion mechanisms of existing rock drilling equipment mostly adopt fixed or single-dimensional adjustment structures, which are difficult to meet the multi-directional drilling requirements such as directional inclined holes, horizontal holes, and vertical holes in tunnel tunneling. For example, the traditional support arm can only swing in a single plane. When multi-angle drilling is required in a complex area of the rock wall, it is necessary to manually move the equipment or adjust the machine position, resulting in large drilling positioning errors and time-consuming and laborious. In addition, the drill rod lacks a dynamic guiding structure during the propulsion process, and is prone to deviation due to the resistance of the rock wall, causing the inclination of the hole to exceed the engineering requirements and affecting the subsequent anchoring or blasting effect.

[0004] During rock drilling operations, a large amount of dust generated by the friction between the drill bit and the rock not only endangers the health of the operators, but also accelerates the wear of components such as drill rods and propulsion beams. The current equipment mostly adopts a simple water spraying dust reduction method. The spray nozzles are fixed and the spraying range is limited, and an effective dust barrier cannot be formed during the drilling process. In addition, the rock debris and dust attached to the surface of the drill rod during its retraction need to be manually cleaned, and the cleaning of a single drill rod takes a long time, which seriously restricts the construction efficiency in deep hole operations. Summary of the Invention

[0005] The purpose of the present invention is to provide a wheeled multi-angle propulsion rock drilling equipment to solve the technical problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solutions.

[0007] A wheeled multi-angle propulsion rock drilling equipment, including a vehicle body, a support arm installed on the vehicle body, a mounting frame installed on the support arm, and a propulsion beam installed on the side of the mounting frame. A circular cover is provided at the end of the propulsion beam. An integrally formed cylinder is fixed to the circular cover. A through hole for the drill rod to pass through is provided on both the cylinder and the circular cover. A spraying mechanism is provided on the circular cover;

[0008] The spraying mechanism includes a driving mechanism, a liquid supply mechanism, and a plurality of spray nozzles. The driving mechanism is arranged inside the circular cover and around the periphery of the cylinder. The plurality of spray nozzles are arranged in a circular array around the cylinder through the driving mechanism. The liquid supply mechanism for supplying liquid to each spray nozzle is arranged outside the circular cover;

[0009] Among them, the driving mechanism is used to switch the spray head between the spray dust suppression mode and the spray cleaning and impurity removal mode.

In the spray cleaning and impurity removal mode, each spray head is arranged obliquely towards the axis of the drill pipe, and the nozzles of each spray head extend out of the circular cover.

[0010] The spray head can switch between the spray dust suppression and the spray cleaning and impurity removal modes, realizing dual functions through a single flushing system. In the spray cleaning and impurity removal mode, each spray head is inclined towards the axis of the drill pipe and the nozzle extends out of the circular cover. When the drill pipe is reset, the liquid can be sprayed to impact its surface, washing away impurities such as attached rock debris and dust, realizing the automatic cleaning of the drill pipe, avoiding relying on manual labor, and solving the problems of time-consuming, laborious and low efficiency of manual cleaning of existing equipment.

[0011] Preferably, a bracket is fixed on the outer peripheral surface of the circular cover, and the bracket is fixed at the end of the propulsion beam.

Rack teeth are fixedly arranged in an array around the axis on the outer wall of the through hole, and each gear meshes with the corresponding rack teeth.

[0013] Preferably, the liquid supply mechanism includes an annular shell, a water supply pipe and a number of diversion pipes. The annular shell is fixedly sleeved on the outer wall of the circular cover. One end of the water supply pipe is communicated with the water pump in the water storage tank arranged on the vehicle body, and the other end is communicated with the annular shell. One end of each diversion pipe is respectively communicated with the corresponding spray head, and the other end is communicated with the annular shell.

[0014] Preferably, a number of air inlet cylinders are evenly distributed in an array around the axis on the back of the circular cover. Each air inlet cylinder is fixedly penetrated through the circular cover and communicated with the inside of the circular cover. A fan is installed in each air inlet cylinder. The fan is used to suck and introduce external air into the circular cover to form a positive pressure. A diffusion cover with a diameter increasing away from the fan is installed on the port of each air inlet cylinder located inside the circular cover. A filter screen is installed upstream of the fan in each air inlet cylinder.

[0015] Preferably, in the spray dust suppression mode, the spray areas of each circular cover are arranged around the drilling opening, and there is an overlapping area between adjacent two spray areas.

[0016] Preferably, a number of through-drawing grooves that all penetrate to the outside are evenly distributed on the side wall of the circular cover. Each diversion pipe passes through the corresponding through-drawing groove, and each diversion pipe is a rubber hose.

[0017] Preferably, the support arm includes a steering mechanism and a three-section swing arm. The three-section swing arm includes a first section arm, a second section arm, and a third section arm, which are connected in sequence and can be swing-adjusted in the first dimension. The first section arm is installed on the vehicle body through the steering mechanism, and the steering mechanism is used to drive the first section arm to rotate and adjust in the second dimension. Among them, the first dimension is perpendicular to the second dimension, and the mounting bracket is installed on the third section arm.

[0018] Preferably, the steering mechanism includes a first hydraulic cylinder and a first steering joint. The first section arm is fixed on the first steering joint. The first steering joint is hinged to the vehicle body through a hinge shaft. One end of the first hydraulic cylinder is hinged to the vehicle body, and the other end is hinged to the first steering joint.

[0019] Preferably, a second hydraulic cylinder is hingedly installed on the third section arm, and a second steering joint is hingedly installed at the end of the third section arm. The end of the telescopic rod of the second hydraulic cylinder is hinged to the second steering joint. A third steering joint is fixed on the side of the second steering joint, and the mounting bracket is installed on the third steering joint. By the telescopic operation of the second hydraulic cylinder, the third steering joint can be driven to swing and adjust in the first dimension.

[0020] Preferably, a third hydraulic cylinder is hingedly installed on the third steering joint, and the mounting bracket is hingedly installed on the third steering joint. The end of the telescopic rod of the third hydraulic cylinder is hinged to the mounting bracket. By the telescopic operation of the third hydraulic cylinder, the mounting bracket can be driven to swing and adjust in the third dimension.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0022] The nozzle can switch between two modes: spray dust suppression and spray cleaning for impurity removal, realizing dual functions through a single flushing system. In the spray cleaning for impurity removal mode, each nozzle is inclined towards the axis of the drill pipe and the spray port extends outside the circular cover. When the drill pipe is reset, the liquid can be sprayed to impact the surface of the drill pipe, washing away impurities such as attached rock debris and dust, realizing the automatic cleaning of the drill pipe, avoiding relying on manual labor, and solving the problems of time-consuming, laborious, and low efficiency of manual cleaning required by existing equipment;

[0023] In the spray dust suppression mode, each nozzle is parallel to the drill pipe and does not extend outside the circular cover. The spray areas of the nozzles arranged in a circular array around the drill pipe form an annular coverage area, and there is an overlapping area between adjacent two spray areas, which can form a circular barrier outside the area where dust is generated during drilling, improving the interception and capture rate of dust and effectively improving the spray dust suppression effect;

[0024] The fan on the back of the circular cover sucks in external air through the air inlet tube and introduces it into the circular cover to form positive pressure. The diffusion cover diffuses the air flow, enabling the air flow to cover a sufficient area inside the circular cover. On the one hand, it can prevent dust from entering the circular cover and polluting the internal components. On the other hand, it can accelerate the droplets sprayed by the nozzles and expand the coverage area of the spraying range, which is applicable to the situation where the distance between the circular cover and the rock surface is relatively far, further improving the dust reduction and cleaning effects and ensuring the normal operation of the equipment;

[0025] The circular cover and the cylinder body form a guiding structure arranged coaxially. Both of them are provided with a through hole for the drill pipe to pass through, which can accurately position and guide the drill pipe, realizing the directional drilling operation of the rock drilling equipment. In the spray dust reduction mode, the driving mechanism drives the nozzle to retract into the circular cover along with the ring body, so that each nozzle does not protrude outside the circular cover, and the shell structure of the circular cover provides physical protection for the nozzle, avoiding the nozzle from colliding and squeezing with the rock wall due to protrusion, and improving the service life of the nozzle and the reliability of the equipment;

[0026] The circular cover and the cylinder body are integrally designed, which not only serves as a guiding part for the drill pipe but also as a protection part for the nozzle, killing two birds with one stone. Brief Description of the Drawings

Specific embodiments

[0039] The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0040] Embodiment 1

[0041] Please refer to Figures 1 - 11 , the present invention provides a wheeled multi-angle propulsion rock drilling equipment, including a vehicle body 1, a support arm 2 installed on the vehicle body 1, a mounting bracket 11 installed on the support arm 2, and a propulsion beam 12 installed on the side of the mounting bracket 11. The vehicle body 1 uses an existing engineering vehicle and is equipped with all-terrain tires to adapt to complex terrain environments. A rock drill is installed on the propulsion beam 12 and is equipped with a driving device. The driving device can drive the rock drill to feed and retract to drill holes of different depths. The specific structure, installation method, and working principle of the driving device and the rock drill all adopt existing technologies, and will not be elaborated in detail in this application.

[0042] A circular cover 3 is provided at the end of the propulsion beam 12. Specifically, a bracket 31 is fixed on the outer peripheral surface of the circular cover 3, and the bracket 31 is fixed at the end of the propulsion beam 12 to realize the fixation of the circular cover 3 and the propulsion beam 12. Among them, an integrally formed cylinder body 32 is fixed to the circular cover 3. The circular cover 3 and the cylinder body 32 are coaxially arranged. A through threading hole 33 is provided on both the circular cover 3 and the cylinder body 32. The drill pipe 01 in the rock drill passes through the threading hole 33 to accurately guide the drill pipe 01 to the rock wall of the required drill hole, avoiding excessive bending of the drill pipe 01 and improving the accuracy of the drill hole position.

[0043] Please refer to Figure 1 and Figure 6, a spray mechanism 4 is provided on the circular cover 3. The spray mechanism 4 has two working modes: spray reward and punishment, and spray cleaning and impurity removal. Among them, the spray mechanism 4 includes a driving mechanism 5, a liquid supply mechanism 7, and a number of spray nozzles 6. The driving mechanism 5 is arranged inside the circular cover 3 and outside the periphery of the cylinder body 32. A number of spray nozzles 6 are arranged in an annular array around the cylinder body 32 through the driving mechanism 5. Specifically, six spray nozzles 6 are provided and arranged in an annular array around the cylinder body 32, and the arrangement angle between adjacent two spray nozzles 6 is 60°, and the point distribution is uniform to ensure sufficient coverage. The liquid supply mechanism 7 is arranged outside the circular cover 3 and is used to guide and supply water to each spray nozzle 6.

[0044] Among them, the driving mechanism 5 is used to switch the spray nozzles 6 between the spray dust suppression mode and the spray cleaning and impurity removal mode. As Figure 8 shown, in the spray dust suppression mode, each spray nozzle 6 is parallel to the drill rod 01. When drilling a rock hole, the spray nozzles 6 spray towards the rock surface to accelerate the settlement of the dust generated by drilling and achieve the effect of dust suppression.

[0045] Dust is mainly generated at the drilling port and drifts outwards. In view of this characteristic, the spray nozzles 6 in the present application are evenly distributed in an annular shape around the drill rod 01. As Figure 11 shown, there is an overlapping area 03 between the spray areas 02 of adjacent two spray nozzles 6, so as to form a closed annular spray coverage area around the drilling hole, and a circular barrier can be formed outside the dust generation area to ensure that there is no escape dead angle for dust, improve the interception and capture rate of dust, reduce dust escape, and thus improve the dust suppression effect.

[0046] As Figure 10 shown, in the spray cleaning and impurity removal mode, each spray nozzle 6 is arranged obliquely towards the axis of the drill rod 01. When the drilling is completed and the drill rod 01 is reset, the liquid sprayed by the spray nozzles 6 impacts on the surface of the drill rod 01, and the dirt attached to the drill rod 01 can be washed clean to realize the automatic cleaning of the drill rod 01.

[0047] Define the angle between the extension direction of the spray nozzle 6 and the drill rod 01 as R. Among them, 20° ≤ R ≤ 50°, so that the liquid sprayed along the spray nozzle 6 can impact obliquely on the outer surface of the drill rod 01 to improve the peeling force on the dirt. In addition, the spray nozzles 6 are evenly distributed in an annular shape around the drill rod 01, and there is an overlap in the liquid spraying and cleaning ranges of adjacent two spray nozzles 6, which is sufficient to cover the circumference of the drill rod 01 to ensure good cleaning effect.

[0048] In addition, the spray mechanism 4 can spray and suppress dust during rock drilling, and can spray and clean impurities when the drill rod 01 retracts and resets, killing two birds with one stone.

[0049] Please refer to Figure 7 and Figure 8The driving mechanism 5 includes a ring body 51, a fourth hydraulic cylinder 52 and a gear 53. The fourth hydraulic cylinder 52 is fixed to the back of the circular cover 3 and extends along the length direction of the through hole 33. The ring body 51 is arranged in the circular cover 3 and is arranged around the cylinder 32. The end of the telescopic rod of the fourth hydraulic cylinder 52 extends through the circular cover 3 and is fixed to the end of the ring body 51. A sliding rod 511 is also fixed to the end of the ring body 51. The sliding rod 511 slides through the circular cover 3. The sliding cooperation of the sliding rod 511 and the circular cover 3 provides a limiting guiding effect for the circular cover 3, ensuring that the circular cover 3 has the ability to move axially along the through hole 33. Through the telescopic work of the fourth hydraulic cylinder 52, the ring body 51 can be driven to perform reciprocating translation adjustment along the axial direction of the through hole 33.

[0050] A plurality of mounting grooves 512 are arranged in a circular array on the ring body 51, and a gear 53 is rotatably installed in each mounting groove 512 through a rotating shaft. A plane 531 is cut out on the outer edge of each gear 53, and an L-shaped frame 54 is fixed on each plane 531. The plane 531 is set on the gear 53, and the L-shaped frame 54 is fixed on the plane 531. The plane 531 can increase the contact area with the L-shaped frame 54, thereby ensuring that the L-shaped frame 54 is installed sufficiently firmly. Each nozzle 6 is fixed on the corresponding L-shaped frame 54, and a rack 55 is fixed on the outer edge wall of the through hole 33 in an array around its axis. Each gear 53 is meshed with the corresponding rack 55.

[0051] When the fourth hydraulic cylinder 52 extends to push the ring body 51 forward, the gear 53 is deflected under the meshing drive of the rack 55, and under the connecting action of the L-shaped frame 54, the nozzle 6 is synchronously deflected to an inclined state, that is, the spray mechanism 4 is adjusted to the spray cleaning and impurity removal mode. When the fourth hydraulic cylinder 52 retracts and drives the ring body 51 to retreat and reset, the rack 55 meshes and drives the gear 53 to rotate and reset, driving the nozzle 6 to rotate to a state parallel to the drill rod 01, that is, the spray mechanism 4 is adjusted to the spray dust reduction mode.

[0052] like Figure 10 In the spray cleaning and impurity removal mode, since the ring body 51 is displaced axially toward the opening side of the circular cover 3 in the through hole 33, the nozzles of each nozzle 6 extend to the outside of the circular cover 3. Combined with the inclined arrangement of the nozzle 6, it can prevent the spray liquid from splashing and mixed with dust particles from entering the circular cover 3, causing pollution to the components inside the dust particles.

[0053] In addition, if Figure 8 As shown, when switched to the spray dust reduction mode, the ring body 51 retracts inward, thereby driving each nozzle 6 to reset to the circular cover 3, ensuring that each nozzle 6 does not extend beyond the outside of the circular cover 3. The circular cover 3 can provide a protective effect for the nozzle 6, avoiding damage to the nozzle 6 due to protruding to the outside of the circular cover 3 and colliding with the rock wall during drilling, thereby increasing the service life of the nozzle 6.

[0054] likeFigure 7 and Figure 8 As shown in Figure 8 , the liquid supply mechanism 7 includes an annular shell 71, a water supply pipe 72 and a plurality of diversion pipes 73. The annular shell 71 is fixedly sleeved on the outer wall of the circular cover 3. One end of the water supply pipe 72 is communicated with a water pump in a water storage tank arranged on the vehicle body 1, and the other end is communicated with the annular shell 71. One end of each diversion pipe 73 is respectively communicated with the corresponding nozzle 6, and the other end is communicated with the annular shell 71. By the operation of the water pump in the water storage tank, the water in the water storage tank is pumped into the annular shell 71 through the water supply pipe 72, and then the water is diverted into each nozzle 6 through each diversion pipe 73, that is, the delivery and supply of water are realized.

[0055] Among them, a plurality of through-drawing grooves 34 that penetrate the outside are evenly distributed on the side wall of the circular cover 3. Each diversion pipe 73 respectively passes through the corresponding through-drawing groove 34. The through-drawing groove 34 is used to make space for the diversion pipe 73 so that the diversion pipe 73 can enter and exit. At the same time, each diversion pipe 73 is made of a rubber hose and has a certain complete deformation ability, and each diversion pipe 73 reserves a certain length to adapt to the position change of the nozzle 6 during the working mode adjustment.

[0056] Embodiment 2

[0057] Please refer to Figures 8 - 10 , the difference between this embodiment and Embodiment 1 is that:

[0058] A plurality of air inlet cylinders 81 are evenly distributed in an array around the axis on the back surface of the circular cover 3. Specifically, four air inlet cylinders 81 are provided and arranged in an array around the axis of the circular cover 3. Each air inlet cylinder 81 is fixedly penetrated through the circular cover 3 and communicated with the inside of the circular cover 3. A fan 8 is installed in each air inlet cylinder 81.

[0059] By the operation of the fan 8, the external air can be sucked into the air inlet cylinder 81 and introduced into the circular cover 3, so that the air pressure in the circular cover 3 increases to form a positive pressure and blows out from the opening of the circular cover 3 to form a flowing air current. When performing spray dust reduction operations during drilling, on the one hand, the flowing air current can prevent dust from entering the circular cover 3 and causing pollution, and on the other hand, it can accelerate the droplets sprayed by the nozzle 6 and expand the coverage area of the spray range, which is suitable for the situation where the distance between the circular cover 3 and the rock surface is relatively far.

[0060] In addition, a diffusion cover 82 with a diameter increasing away from the fan 8 is installed on the port of each air inlet cylinder 81 located inside the circular cover 3. The diffusion cover 82 can be used to diffuse the air current to ensure that the air current generated by the operation of the four fans 8 has a sufficient coverage area inside the circular cover 3, and a filter screen 83 is installed at the upstream of the fan 8 in each air inlet cylinder 81 to filter out dust impurities in the external air.

[0061] Embodiment 3

[0062] Please refer toFigures 1 - 5 , the difference between this embodiment and the second embodiment is that:

[0063] The support arm 2 includes a steering mechanism 21 and a three - section swing arm 22. The three - section swing arm 22 includes a first - section arm 221, a second - section arm 222, and a third - section arm 223, which are connected in sequence. Moreover, the angle between the first - section arm 221 and the second - section arm 222 can be adjusted in the first dimension, and the angle between the second - section arm 222 and the third - section arm 223 can be adjusted in the first dimension. The specific structure and working principle are similar to those of the boom of an excavator in the prior art, and will not be elaborated in detail in this application.

[0064] Among them, the first - section arm 221 is installed on the vehicle body 1 through the steering mechanism 21. The steering mechanism 21 is used to drive the first - section arm 221 to rotate and adjust in the second dimension. Among them, the first dimension is perpendicular to the second dimension, and the mounting bracket 11 is installed on the third - section arm 223.

[0065] As Figure 3 shown, the steering mechanism 21 includes a first hydraulic cylinder 211 and a first steering joint 212. The first - section arm 221 is fixed on the first steering joint 212. The first steering joint 212 is hinged to the vehicle body 1 through a hinge shaft. One end of the first hydraulic cylinder 211 is hinged to the vehicle body 1, and the other end is hinged to the first steering joint 212. By the telescopic operation of the first hydraulic cylinder 211, it can drive the first steering joint 212 to swing relative to the vehicle body 1, and then drive the first - section arm 221 to swing synchronously, realizing the swing adjustment of the entire three - section swing arm 22 in the second dimension.

[0066] As Figure 4 shown, a second hydraulic cylinder 23 is hinged and installed on the third - section arm 223. A second steering joint 24 is hinged and installed at the end of the third - section arm 223. The end of the telescopic rod of the second hydraulic cylinder 23 is hinged to the second steering joint 24. A third steering joint 25 is fixed on the side of the second steering joint 24. The mounting bracket 11 is installed on the third steering joint 25. By the telescopic operation of the second hydraulic cylinder 23, it can drive the second steering joint 24 to swing relative to the third - section arm 223, and then drive the entire third steering joint 25 and the mounting bracket 11 to swing and adjust in the first dimension.

[0067] As Figure 5 shown, a third hydraulic cylinder 26 is hinged and installed on the third steering joint 25. The mounting bracket 11 is hinged and installed on the third steering joint 25. The end of the telescopic rod of the third hydraulic cylinder 26 is hinged to the mounting bracket 11. By the telescopic operation of the third hydraulic cylinder 26, it can drive the mounting bracket 11 to swing and adjust relative to the third steering joint 25 in the third dimension.

[0068] It can be seen that the support arm 2 includes three articulated arms 22 capable of angle adjustment. The first hydraulic cylinder 211 drives the first steering joint 212 to swing in the second dimension, the second hydraulic cylinder 23 drives the third steering joint 25 to swing in the first dimension, and the third hydraulic cylinder 26 drives the mounting bracket 11 to swing in the third dimension. Combining the swinging adjustment effect of the three articulated arms 22 similar to the boom of an excavator, a multi-degree-of-freedom adjustment system is formed, enabling the drill pipe 01 on the side of the propulsion beam 12 to drill holes with multi-angle propulsion in space and meeting the needs of drilling holes at different angles.

[0069] In summary, the spraying mechanism 4 in the circular cover 3 switches the working mode of the nozzle 6 through the drive mechanism 5, that is, the spraying and dust suppression mode where the nozzle 6 is parallel to the drill pipe 01 and the spraying and impurity removal mode where the nozzle 6 is inclined relative to the drill pipe 01. Combining with the positive pressure airflow to suppress the intrusion of dust, this design realizes the precise multi-angle propulsion and efficient operation of the drill pipe 01 under complex working conditions through the multi-dimensional coordinated movement of the robotic arm and the adaptive cleaning system.

[0070] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
