[0040] The plurality of drill tube mechanisms are respectively and correspondingly arranged on the top strip guide rail, the second upper side strip guide rail and the second side strip guide rail.

[0049] As can be seen from the above description, this structure enables horizontal cutting of the interior of the rock tunnel face after the drill barrel mechanism is operated. During machining, the two front guide wheels extend to the front end of the front frame. The drill barrel mechanism forms a cylindrical space, and the front guide wheels move inward from this cylindrical space to achieve cutting of the center portion.

[0050] Furthermore, a square sleeve is provided on each side of the rear frame, and a slidably connected strip cross bar is provided in the square sleeve, the two strip cross bars form the two long sides of the rectangle, and the two front guide wheels and the two rear guide wheels are respectively provided at the ends of the two strip cross bars; a connecting cross bar is provided between the two strip cross bars at one end of the rear guide wheel, one end of the connecting cross bar is rotatably connected to one of the two strip cross bars, and the other end of the connecting cross bar is detachably connected to the other of the two strip cross bars.

[0051] It can be seen from the above description that the above structure can realize the forward and backward movement of the rope saw mechanism and ensure the overall structural stability.

[0052] Furthermore, there are two rope saw mechanisms, which are parallel to each other and spaced apart from each other. A connecting frame is provided between the two rope saw mechanisms, and both ends of the connecting frame are fixedly connected to the bar cross bars of the two rope saw mechanisms.

[0053] As can be seen from the above description, the two rope saw mechanisms can be operated synchronously to improve processing efficiency. The connection via the connecting frame can improve the stability of the overall structure.

[0054] Furthermore, the rear frame is in the shape of an arch; a hook assembly is provided on the inner top surface of the rear frame corresponding to the arch.

[0055] As can be seen from the above description, after being cut by the rope saw mechanism, the cut stones are pulled out by the hook assembly.

The drive shaft of the trimming motor is fixedly connected to the trimming saw blade. The trimming saw blades of multiple trimming mechanisms together form the arch.

[0057] As can be seen from the above description, the trimming mechanism can be used to perform trimming operations on the protruding portion of the outer edge of the rock tunnel surface after the rope saw mechanism is operated.

[0058] Furthermore, the trimming mechanism further comprises a mounting plate, one side of the mounting plate is fixedly connected to the transmission shaft of the trimming motor, and the other side of the mounting plate is fixedly connected to the trimming saw blade via an embedded bolt.

[0062] Furthermore, the lower part of the front frame is provided with a walking wheel and a trenching motor mechanism arranged in front of the walking wheel. The trenching motor mechanism includes a trenching motor and a trenching saw blade arranged vertically and connected to the transmission shaft of the trenching motor. The diameter of the trenching saw blade is adapted to the width of the walking wheel.

[0063] From the above description, it can be seen that a planing motor mechanism is provided. When the frame is pushed forward, the planing saw blade will plane grooves in the ground to form channels for the travel wheels to move, and can also regulate the travel route of the entire mechanism.

[0064] Furthermore, the trenching motor mechanism also includes a semi-enclosed protective plate, which is sleeved on the periphery of the trenching motor; the transmission shaft of the trenching motor is a hollow rotating shaft, one end of the hollow rotating shaft of the trenching motor is connected to an external water pipe through a rotating joint, and a water outlet is provided at the center of the planing saw blade, and the other end of the hollow rotating shaft of the trenching motor is connected to the water outlet.

[0066] Furthermore, a hydraulic cylinder assembly is provided between the front frame and the rear frame, and two ends of the hydraulic cylinder assembly are fixedly connected to opposite surfaces of the front frame and the rear frame respectively.

[0067] As can be seen from the above description, the provision of the hydraulic cylinder assembly can not only propel the front frame, but also, when propulsion is obstructed, such as when it is stuck, the hydraulic cylinder assembly can be used to pull the front frame backward.

[0068] Furthermore, the upper portion of the front frame and the lower portion of the front frame are detachably connected.

[0069] From the above description, it can be seen that the upper and lower parts of the front frame are detachably connected. When advancement is blocked, the upper part of the front frame can be supported by the support members, the upper and lower parts can be separated, the lower part can be pulled out, and then the top part can be pulled out.

[0070] Application Scenario

[0071] The multifunctional rock tunnel drilling and cutting machine provided by the present invention is mainly used for the construction of rock tunnels, especially small rock tunnels.

[0072] See Figures 1-16 , Example 1

[0073] The present invention provides a multifunctional rock tunnel drilling and cutting machine, comprising a frame and a drill tube mechanism 3, a wire saw mechanism 4 and a trimming mechanism 5 respectively arranged on the frame;

[0074] The frame includes a front frame 1 and a rear frame 2;

[0075] The front frame 1 is in the shape of an arch; a top strip guide rail 11 extending in the horizontal direction is provided on the upper surface of the front frame 1 corresponding to the top surface of the arch; the number of the top strip guide rail 11 is one, and a drill barrel mechanism is disposed on the top strip guide rail 11, which can reciprocate in the horizontal direction;

[0076] The front frame 1 is provided with a first upper side bar rail 12 extending along the horizontal direction on the upper side corresponding to the arch shape, and a second upper side bar rail 121 provided on the first upper side bar rail 12 and perpendicular to the first upper side bar rail.

Each of the second upper side bar rails 121 is provided with a drill cylinder mechanism. The drill cylinder mechanism provided on the second upper side bar rail can move reciprocally along the horizontal direction and the direction perpendicular to the horizontal direction on the side.

[0077] The front frame 1 is provided with a first side bar rail 13 extending along the horizontal direction on the side corresponding to the arch shape, and a second side bar rail 131 provided on the first side bar rail 13 and perpendicular to the first side bar rail. The number of the second side bar rails 131 is two, symmetrically distributed on the left and right sides of the top bar rail and located below the first upper side bar rail 12. Each of the second side bar rails 131 is provided with two parallel drill cylinder mechanisms. The drill cylinder mechanism provided on the second side bar rail can move reciprocally along the horizontal direction and the direction perpendicular to the horizontal direction on the side.

[0078] In the embodiment, the drill cylinder mechanism 3 is used for drilling operation on the outer edge of the rock tunnel surface 6 to be processed. The drill cylinder mechanism located on the top bar rail only moves along the rail. The drill cylinder mechanism located on the second upper side bar rail and the second side bar rail can move in two-dimensional plane direction, which can reduce the number of drill cylinder mechanisms. The number of the drill cylinder mechanisms is seven. Of course, the number can be configured according to actual needs. The plurality of drill cylinder mechanisms are distributed in the shape of an arch along the outer edge of the front frame, and the plurality of drill cylinder mechanisms can move synchronously along the horizontal direction.

[0079] The drill barrel mechanism 3 comprises a drill barrel motor 31, a connecting box 32 in the shape of a cuboid and a drill barrel 33 in the shape of a cylinder which are arranged in sequence along the horizontal direction, the transmission shaft of the drill barrel motor 31 is in transmission connection with the drill barrel 33 through the connecting box 32, and the abutment positions are connected by flanges. Specifically, the transmission shaft of the drill barrel motor 31 is a hollow rotating shaft, the connecting box 32 is internally provided with a hollow connecting shaft, one end of the hollow rotating shaft of the drill barrel motor 31 is connected with an external water pipe 34 through a rotating joint, the other end of the hollow rotating shaft of the drill barrel motor 31 is fixedly connected with one end of the hollow connecting shaft through a flange and is in communication with each other, and the other end of the hollow connecting shaft is in communication with the inside of the drill barrel. In use, the water in the external water pipe passes through the hollow rotating shaft and the hollow connecting shaft to the inside of the drill barrel, so that the friction heat generated during the operation of the drill barrel can be cooled, and the machining effect is improved. In this embodiment, the vertical section of the connecting box is square, and the diagonal of the square corresponding to the connecting box is smaller than the diameter of the circular section corresponding to the drill barrel.

[0080] The drill barrel 33 is provided with a circular opening 331 at the end away from the drill barrel motor, the edge of the circular opening 331 is provided with a plurality of uniform and spaced sawtooth portions 3311 which extend along the horizontal direction. That is, the circular opening faces the machined surface.

[0081] The connecting box 32 is provided with a sliding block 321 on the outer side surface; the sliding block on the drill barrel mechanism corresponding to the top strip-shaped guide rail is arranged in the top strip-shaped guide rail and can move along the top strip-shaped guide rail; the sliding block on the drill barrel mechanism corresponding to the second upper side surface strip-shaped guide rail is arranged in the second upper side surface strip-shaped guide rail and can move along the second upper side surface strip-shaped guide rail; and the sliding block on the drill barrel mechanism corresponding to the second side surface strip-shaped guide rail is arranged in the second side surface strip-shaped guide rail and can move along the second side surface strip-shaped guide rail. Through the above structure, the drill barrel mechanism can move on the corresponding strip-shaped guide rail.

[0082] The wire saw mechanism 4 is arranged on the rear frame and has a movement direction that is the same as that of the drill barrel mechanism. The wire saw mechanism 4 is used to perform horizontal cutting operations on the interior of the rock tunnel face after the drill barrel mechanism is operated. The wire saw mechanism 4 includes a wire saw drive motor 41, a flywheel 42, a wire saw chain 43, two front guide wheels 44, and two rear guide wheels 45. The two front guide wheels 44 and the two rear guide wheels 45 are all arranged horizontally. The two front guide wheels 44 and the two rear guide wheels 45 are collectively arranged corresponding to the four vertices of a rectangle. The transmission shaft of the wire saw drive motor 41 is fixedly connected to the flywheel 42. The flywheel 42 is arranged between the two rear guide wheels 45. The wire saw chain 43 is collectively wound around the flywheel 42, the two front guide wheels 44, and the two rear guide wheels 45. The central axes of the two front guide wheels 45 intersect with the central axes of the drill barrel 33 of the drill barrel mechanism located on both sides of the front frame, and the radius of the front guide wheel 45 is no greater than the radius of the drill barrel 33.

[0083] In this embodiment, the rear frame 2 is provided with a square sleeve on each side, each containing a slidably connected strip crossbar 46. The crossbar 46 is shaped to match the sleeve and slightly smaller than the sleeve. To facilitate sliding, a lubricant may be applied to the contact surface between the two crossbars 46. The two crossbars 46 form the two long sides of the rectangle, with two front guide wheels 44 and two rear guide wheels 45 respectively located at the ends of the two crossbars. A connecting crossbar 47 is provided between the two crossbars 46 at one end of the rear guide wheels. One end of the connecting crossbar 47 is rotatably connected to one of the two crossbars, and the other end of the connecting crossbar 47 is detachably connected to the other of the two crossbars.

[0084] When the above-mentioned rope saw mechanism is in operation, the rope saw chain is not first placed on the guide wheel. The strip crossbar is first moved forward so that the two front guide wheels extend to the front end of the front frame. The rope saw chain is then placed on to form a rope saw mechanism for operation. After operation, the rope saw chain is removed. The strip crossbar is then moved backward so that the two front guide wheels return to their initial positions (i.e., located on both sides of the rear frame, mainly to avoid affecting the operation of the subsequent trimming mechanism). After the rope saw mechanism is completed, the cut stone is pulled out by the hook assembly provided on the rear frame. The other end of the connecting crossbar can be detachably connected to meet the removal of the stone. The rotatable connection can be achieved by using an existing shaft structure, and the detachable connection can be achieved by using an existing pin structure. It should be noted that after the operation of the drill barrel mechanism, a cylindrical space is formed, and the front guide wheel moves inward from the cylindrical space to achieve the cutting operation on the middle part.

[0085] In this embodiment, two wire saw mechanisms are arranged parallel to each other and spaced apart. A connecting frame 48 is provided between the two wire saw mechanisms. The ends of the connecting frame are fixedly connected to the crossbars of the two wire saw mechanisms. This allows the two wire saw mechanisms to operate synchronously, improving processing efficiency. The connection via the connecting frame enhances overall structural stability.

[0086] The rear frame 2 is arch-shaped; a hook assembly is provided on the inner top surface of the rear frame 2 corresponding to the arch. Multiple trimming mechanisms are distributed in an arch-like pattern along the outer edge of the rear frame, with the trimming mechanisms located at the sides staggered relative to the drilling mechanism. The trimming mechanisms are used to trim the protruding portions of the outer edge of the rock tunnel surface after the rope saw mechanism has been operated. Specifically, the trimming mechanism 5 is mounted on the front end of the rear frame via a universal joint. The trimming mechanism 5 includes a trimming motor and a trimming saw blade. The drive shaft of the trimming motor is fixedly connected to the trimming saw blade. The trimming saw blades of the multiple trimming mechanisms collectively form the arch.

[0087] In this embodiment, the trimming mechanism further includes a mounting plate, one side of which is fixedly connected to the transmission shaft of the trimming motor, and the other side of which is fixedly connected to the trimming saw blade via an embedded bolt. Through the above structure, the trimming saw blade can be brought closer to the cutting surface, thereby improving the cutting effect. The trimming mechanism further includes a semi-enclosed protective plate, which is sleeved on the periphery of the trimming motor; the transmission shaft of the trimming motor is a hollow rotating shaft, one end of the hollow rotating shaft of the trimming motor is connected to an external water pipe via a rotating joint, a water outlet is provided at the center of the trimming saw blade, and the other end of the hollow rotating shaft of the trimming motor is connected to the water outlet. The provision of a semi-enclosed protective plate can prevent water from entering the motor and affecting its performance.

[0088] The working principle of the multifunctional rock tunnel drilling and cutting machine provided by the present invention is as follows:

[0089] During drilling, the drill barrel on the front frame faces the surface to be machined (the rock tunnel). Water is supplied through an external water pipe. The seven drill barrels move forward synchronously, and the drill barrel motor drives the drill barrels to rotate, simultaneously drilling the rock tunnel surface. After the drilling operation is completed, the seven drill barrels move synchronously backward to their initial positions. The positions of the drill barrel mechanisms on the second upper side bar guide rail and the second side bar guide rail are then adjusted. In this embodiment, each of the second upper side bar guide rail and the second side bar guide rail has two positions. That is, after the first drilling operation, the position is adjusted to the other position, and the drilling operation is repeated. Since the drill barrel mechanism on the top surface can only move horizontally, it does not need to move forward during the second drilling operation; only the remaining six drill barrels need to move forward. Before the second drilling operation, the two front guide wheels of the wire saw mechanism need to be extended to the front end of the front frame. The specific operation is as described above and will not be repeated here. It should be noted that the adjustment of the drill barrel mechanism on the side to the other position is to make way for the wire saw mechanism to extend to the front end. Then the rope saw mechanism is pushed forward together with the drill barrel to perform the second drilling barrel operation and cutting operation, and then retracted together after the operation.

[0090] A walking trolley can be set inside the front frame, and the stone cut from the middle can be placed on the walking trolley. A mounting part compatible with the hook can be processed on the stone. The hook in the hook assembly on the rear frame is locked with the mounting part to pull the stone out.

[0091] After the rope saw operation is completed, the rope saw mechanism returns to its original position, and the trimming motor is driven to perform a trimming operation on the outer edge protrusion formed after the drill tube mechanism is operated.

[0092] The construction cost is calculated based on a hole with a diameter of 2.5 meters (19 holes need to be drilled) as follows:

[0093] The drilling work is 500 yuan per day, with a crew fee of 2 people x 500 = 1,000 yuan. 19 holes drilled x 0.3 meter diameter x 3.14 meter circumference x 2 meter depth equals 35 square meters. The wear and tear cost of the deep-hole core-pulling tool is 5 yuan per square meter. 35 square meters x 5 yuan per square meter = 105 yuan per 2 meters of rock. The wear and tear cost of the wire saw tool is 10 yuan per square meter. Cutting two surfaces per 2 meters of rock with a depth of 1.8 meters and a width of 1.8 meters equals 7 square meters x 10 yuan per square meter = 70 yuan per 2 meters of rock. The circular saw trimming area is a flat arc with a circumference of 7 meters x 2 meters = 14 square meters. The tool fee per square meter is 3 yuan; 7 meters x 3 yuan = 21 yuan per 2 meters of rock. The electricity cost is an average of 4 yuan per square meter for all three cutting machines. The total area of ​​the three cutting machines is 35 square meters for the drill pipe, 7 square meters for the wire saw, and 7 square meters for trimming, totaling 49 square meters. 49 square meters x 4 yuan per square meter = 196 yuan.

[0094] To summarize, the labor cost per two rock meters is 1,000 yuan, the drill costs 105 yuan, the wire saw costs 70 yuan, the circular cutter costs 21 yuan, and the electricity costs 196 yuan = a total cost of 1,392 yuan per two rock meters, which translates to about 700 yuan per rock meter. 700 yuan / 5 cubic meters per rock meter = 140 yuan per cubic meter.

[0095] The current market price for extraction using a water-abrasive drill is over 1,000 yuan per cubic meter; blasting costs over 500 yuan. This machine costs around 100-140 yuan per cubic meter, far below the current market price. Larger holes can be made at lower costs, as the drill bit size is only slightly larger, and the volume per cubic meter is doubled, making construction easier. The average cost for a large hole is around 100 yuan per cubic meter.

[0096] This equipment also features an electrical control room, which houses safety equipment and supplies such as emergency oxygen, fire extinguishers, and medications. During normal drilling and cutting operations, workers operate from within the room. Compared to other tunneling methods, this machine offers higher efficiency, lower workload, and greater safety. Furthermore, the resulting sized stone can be sold at a high market price, generating significant profits for both the construction company and the enterprise.

[0098] Based on the above-mentioned first embodiment, the front frame structure is further improved. Specifically, the lower portion of the front frame 1 is provided with a running wheel 14 and a trenching motor mechanism located in front of the running wheel. The trenching motor mechanism includes a trenching motor 15 and a vertically arranged trenching saw blade 16 connected to the drive shaft of the trenching motor. The diameter of the trenching saw blade matches the width of the running wheel. The trenching motor mechanism is provided so that when the frame advances forward, the trenching saw blade trenches the ground, forming a channel for the running wheel to move, thereby regulating the path of the entire mechanism. The trenching motor mechanism also includes a semi-enclosed protective plate that is sleeved around the periphery of the trenching motor. The drive shaft of the trenching motor is a hollow shaft, one end of which is connected to an external water pipe via a rotary joint. A water outlet is provided at the center of the trenching saw blade, and the other end of the hollow shaft of the trenching motor is connected to the water outlet. A semi-enclosed protective plate is provided to prevent water from entering the motor and affecting its performance.

[0099] Example 3

[0100] In addition to the first embodiment, a hydraulic cylinder assembly is provided between the front and rear frames, with both ends of the hydraulic cylinder assembly fixedly connected to opposing surfaces of the front and rear frames, respectively. The hydraulic cylinder assembly not only propels the front frame but also allows the front frame to be pulled rearward if propulsion is obstructed, such as if it becomes stuck.

[0101] Embodiment four

[0102] Embodiment four is an alternative or further technical solution of embodiment three. Specifically, the upper portion of the front frame is detachably connected with the lower portion of the front frame. The upper portion of the front frame is detachably connected with the lower portion of the front frame. When the pushing is blocked, the upper portion of the front frame can be supported in combination with the support member, the upper and lower portions are separated, and then the lower portion is extracted, and then the upper portion is extracted.

[0103] The above description is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent transformation or direct or indirect application in the related technical field based on the content of the specification and drawings is also included in the patent protection scope of the present application.
