A multi-functional anchor bolt drilling rig is a self-propelled mechanized equipment that integrates multiple operational functions. It is mainly used for ground reinforcement and support construction in mining, tunneling, and underground engineering fields. It can complete multiple support processes such as drilling, grouting, and anchor bolt or anchor cable installation within the same work cycle, significantly improving construction efficiency and safety, and reducing equipment replacement frequency and labor intensity. A search revealed that patent document CN116398201B discloses a multi-functional single-arm anchor bolt drilling rig, comprising a vehicle body and an anchor bolting section; an I-beam clamping groove is provided on the top of the anchor bolting section; a vertical lifting assembly is provided on the vehicle body, and a rotating assembly is provided on the vertical lifting assembly; the vertical lifting assembly drives the rotating assembly to lift and lower, and the rotating assembly drives the anchor bolting section to rotate; the anchor bolting section includes a drill arm assembly and an anchor cable clamping assembly. The beneficial effects of this invention are: by providing an I-beam clamping groove on the top of the anchor bolting section, the single-arm anchor bolt drilling rig realizes the functions of driving anchor bolts and transporting I-beams to the top of the roadway, improving the efficiency of anchor support work; the single-arm anchor bolt drilling rig has a vehicle body width of 900mm to 1200mm, enabling it to perform anchor bolt driving, I-beam lifting, and other operations on both sides of the bridge transfer conveyor, achieving multiple functions with a single unit, realizing coordinated operations of anchor bolt driving, anchor cable, and I-beam lifting, improving support efficiency and reducing labor intensity.

[0003] The aforementioned patent claims demonstrate that the anchor bolt can be vertically raised and lowered, rotated left and right, and swung back and forth, but the left and right swinging function is not demonstrated, the drilling range is limited, and it is not possible to complete the construction of all anchor bolt holes in one go. In addition, the I-beam clamp does not have the left and right swinging function, and it cannot avoid the ventilation duct during the lifting process. Summary of the Invention

[0004] The purpose of this invention is to address the problems mentioned in the background section by providing a multi-functional anchor drilling rig.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions: A multi-functional anchor bolt drilling rig includes a drilling rig body, with a bulldozer blade hinged to the lower front end of the drilling rig body. The bulldozer blade consists of a bulldozer blade cylinder and a blade plate. One end of the bulldozer blade cylinder is hinged to the drilling rig body, and the other end is hinged to the blade plate. The front end of the drilling rig body is provided with a working arm assembly. The working arm assembly includes a rear hinge seat fixed to the front end of the drilling rig body. A telescopic arm is hinged to the upper end of the rear hinge seat. Two boom lifting cylinders are placed between the rear hinge seat and the telescopic arm. Controlling the boom lifting cylinders can realize the lifting and lowering and left and right swinging of the telescopic arm. The working arm assembly also includes a front hinge seat hinged to the front end of the telescopic arm. The front hinge seat is provided with an axial swing cylinder. A pitch cylinder is provided between the telescopic arm and the front hinge seat. Controlling the extension and retraction of the pitch cylinder can realize the pitch movement of the front hinge seat relative to the telescopic arm. An anchor bolt assembly is provided at the front end of the working arm assembly. The anchor bolt assembly includes a front connecting seat. The front connecting seat is placed at the front end of the front hinge seat via an axial swing cylinder. A hydraulic anchor bolt drill and a lifting arm are hung on the left and right sides of the front connecting seat, and an anchor cable propulsion assembly is placed above the hydraulic anchor bolt drill.

[0006] Preferably, the anchor cable propulsion assembly has a clamping function and an anchor cable propulsion function. The anchor cable propulsion assembly includes a mounting plate and a clamp. The clamp is symmetrically arranged on the left and right sides above the mounting plate. An anchor cable propulsion device is placed on the other side of the mounting plate, and a front top plate is provided on the outside. The anchor cable advancer includes an active roller bracket and a driven roller bracket, which are respectively hinged to the left and right sides of the mounting plate. An active wheel is fixed above the active roller bracket and is driven by a hydraulic motor. A driven wheel is placed above the driven roller bracket. A connecting rod is placed between the active roller bracket and the driven roller bracket. A rotating cylinder is provided below the driven roller bracket. One end of the rotating cylinder is hinged to the mounting plate, and the other end is hinged to the driven wheel bracket. By controlling the extension and retraction of the rotating cylinder, the distance between the active wheel and the driven wheel can be adjusted, thereby applying an appropriate clamping force to the anchor cable to be advanced. Then, by rotating the active wheel, the anchor cable can be pushed into the hole.

[0007] Preferably, the lifting arm includes an outer cylinder, a telescopic hydraulic rod, and an inner cylinder. One end of the telescopic hydraulic rod is hinged to the outer cylinder, and the other end is hinged to the inner cylinder. Controlling the extension and retraction of the telescopic hydraulic rod can realize the extension and retraction of the inner cylinder relative to the outer cylinder. A rotary reducer is fixedly connected to the inner cylinder. A clamping jaw fixing plate is fixedly connected to the inner ring of the rotary reducer. Controlling the relative rotation of the inner and outer rings of the rotary reducer can realize the left and right rotation of the clamping jaw fixing plate. Several clamping jaw plates are placed above the clamping jaw fixing plate for clamping the I-beam.

[0008] Preferably, the front connecting seat consists of a connecting plate, an upper swing cylinder, and a lower swing cylinder. The upper swing cylinder is connected to the lifting arm and can control the forward and backward rotation of the lifting arm. An anchor bolting machine is fixedly connected to the lower swing cylinder and can control the forward and backward rotation of the anchor bolting machine.

[0009] Preferably, the rear hinge seat is composed of a fixed seat, an upper cross hinge joint, and a lower cross hinge joint. The upper cross hinge joint is hinged above the fixed seat, and the lower cross hinge joint is symmetrically hinged below the fixed seat.

[0010] Preferably, an operating platform is fixed above the front hinge seat, and a lifting platform and an anchor bolt platform are placed below the left and right ends respectively.

[0011] Preferably, the clamp consists of a valve body, a guide rod, and a clamping block. The guide rod is telescopic relative to the valve body, and a clamping block is fixed at the front end of the guide rod. When the guide rod extends, it can drive the clamping block to clamp the drill rod, which facilitates the disassembly of the drill rod.

[0012] Preferably, the bulldozer blade, in addition to its bulldozing function, also provides stable support during the drilling process.

[0013] Compared with existing technologies, the advantages of this multi-functional anchor bolt drilling rig are: This invention features a boom assembly that, through the coordinated operation of a cross-hinged joint, boom lifting cylinder, pitch cylinder, and axial swing cylinder, enables multi-dimensional movements such as lifting and lowering of the telescopic boom, left and right swinging, up and down pitching of the front hinge seat, and axial rotation of the anchor bolt assembly. This gives the anchor bolt assembly all-around spatial positioning capabilities, allowing it to accurately reach any working hole and support position without repeated repositioning. A single positioning operation can complete drilling of multiple surrounding anchor bolt holes, anchor cable installation, and I-beam support work. This overcomes the drawbacks of traditional anchor bolt drilling rigs, which have limited drilling range and require multiple positioning operations, significantly improving positioning efficiency and work coverage.

[0014] This invention integrates the functions of site preparation, precise positioning, anchor drilling, anchor cable advancement, and I-beam support, constructing a complete support operation cycle. It eliminates the need to replace multiple pieces of equipment during construction, reducing the time wasted on equipment relocation and debugging. At the same time, the various processes are seamlessly connected. Anchor cable advancement can be carried out directly after drilling is completed, and I-beam support and anchor drilling operations can be carried out in tandem. This effectively reduces the workload of operators in connecting the various processes, significantly reduces the intensity of manual labor, and improves the overall operational efficiency of support construction.

[0015] The bulldozer blade of this invention has dual functions of bulldozing and clearing obstacles as well as stabilizing support. During operation, the blade is lowered to fit the ground, and the ground reaction force is used to counteract the reaction force generated by drilling and anchor cable propulsion, preventing the main body of the drilling rig from shifting and eliminating the need for additional auxiliary support structures. On the other hand, the clamp of the anchor cable propulsion component can clamp the drill rod during drilling to prevent the drill rod from shaking and affecting the drilling accuracy. The front top plate during anchor cable propulsion can guide and limit the anchor cable, ensuring the accuracy of anchor cable installation. These multiple designs greatly improve the stability of equipment operation and construction accuracy. Attached Figure Description

[0019] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] Example: Refer to Figures 1 to 9 A multi-functional anchor drilling rig includes a drilling rig body 1, with a bulldozer blade 2 hinged to the lower front end of the drilling rig body 1. The bulldozer blade 2 consists of a bulldozer blade cylinder and a blade plate. One end of the bulldozer blade cylinder is hinged to the drilling rig body 1, and the other end is hinged to the blade plate. In addition to its bulldozing function, the bulldozer blade 2 also provides stable support during the drilling process.

[0021] To further explain, such as Figure 2 and Figure 3 As shown, a working arm assembly 3 is located at the front end of the drilling rig body 1. The working arm assembly 3 includes a rear hinge seat 31 fixed to the front end of the drilling rig body 1. A telescopic arm 33 is hinged to the upper end of the rear hinge seat 31. Two boom lifting cylinders 32 are located between the rear hinge seat 31 and the telescopic arm 33. Controlling the boom lifting cylinders 32 can realize the lifting and lowering and left and right swinging of the telescopic arm 33. When the two boom lifting cylinders 32 extend at the same time, the drilling arm can be lifted. When the two boom lifting cylinders 32 extend and retract at the same time, the drilling arm can be swung left and right. The working arm assembly 3 also includes a front hinge seat 38 hinged to the front end of the telescopic arm 33. An axial swing cylinder 37 is provided on the front hinge seat 38. A pitch cylinder 34 is provided between the telescopic arm 33 and the front hinge seat 38. By controlling the extension and retraction of the pitch cylinder 34, the pitch action of the front hinge seat 38 relative to the telescopic arm 33 can be realized. An anchor bolt assembly 4 is provided at the front end of the working arm assembly 3. The anchor bolt assembly 4 includes a front connecting seat 42. The front connecting seat 42 is placed at the front end of the front hinge seat 38 via an axial swing cylinder 37. A hydraulic anchor bolt drill 44 and a lifting arm 41 are hung on the left and right sides of the front connecting seat 42, respectively. An anchor cable propulsion assembly 43 is placed above the hydraulic anchor bolt drill 44. An operating platform 35 is fixed above the front hinge seat 38. A lifting platform 36 and an anchor bolt platform 39 are placed below the left and right ends, respectively.

[0022] To elaborate further, such as Figure 4 and Figure 5 As shown, the anchor cable propulsion assembly 43 has a clamping function and an anchor cable propulsion function. The anchor cable propulsion assembly 43 includes a mounting plate 431 and a clamp 432. The clamp 432 is symmetrically arranged on the left and right sides above the mounting plate 431. An anchor cable propulsion device 434 is placed on the other side of the mounting plate 431, and a front top plate 433 is provided on the outside. The anchor cable pusher 434 includes an active roller bracket 4341 and a driven roller bracket 4342. The active roller bracket 4341 and the driven roller bracket 4342 are respectively hinged to the left and right sides of the mounting plate 431. An active wheel 4343 is fixed above the active roller bracket 4341 and is driven by a hydraulic motor. A driven wheel 4344 is placed above the driven roller bracket 4342. A connecting rod 4345 is placed between the active roller bracket 4341 and the driven roller bracket 4342. A rotating cylinder 4346 is provided below the driven roller bracket 4342. One end of the rotating cylinder 4346 is hinged to the mounting plate 431 and the other end is hinged to the driven wheel 4344 bracket. By controlling the extension and retraction of the rotating cylinder 4346, the distance between the active wheel 4343 and the driven wheel 4344 can be adjusted, thereby applying an appropriate clamping force to the anchor cable to be pushed. Then, by rotating the active wheel 4343, the anchor cable can be pushed into the hole.

[0023] To further explain, such as Figure 6 As shown, the lifting arm 41 includes an outer cylinder 411, a telescopic hydraulic rod 412, and an inner cylinder 413. One end of the telescopic hydraulic rod 412 is hinged to the outer cylinder 411, and the other end is hinged to the inner cylinder 413. Controlling the extension and retraction of the telescopic hydraulic rod 412 can realize the extension and retraction of the inner cylinder 413 relative to the outer cylinder 411. A rotary reducer 414 is fixedly connected to the inner cylinder 413. A gripper fixing plate 415 is fixedly connected to the inner ring of the rotary reducer 414. Controlling the relative rotation of the inner and outer rings of the rotary reducer 414 can realize the left and right rotation of the gripper fixing plate 415. Several gripper plates 416 are placed above the gripper fixing plate 415 for clamping the I-beam.

[0024] To elaborate further, such as Figure 7 As shown, the front connecting seat 42 is composed of a connecting plate 421, an upper swing cylinder 422 and a lower swing cylinder 423. The upper swing cylinder 422 is connected to the lifting arm 41 and can control the forward and backward rotation of the lifting arm 41. The lower swing cylinder 423 is fixedly connected to the anchor bolting machine 44 and can control the forward and backward rotation of the anchor bolting machine 44.

[0025] To further explain, such as Figure 8 As shown, the rear hinge seat 31 is composed of a fixed seat 311, an upper cross hinge joint 313, and a lower cross hinge joint 312. The upper cross hinge joint 313 is hinged above the fixed seat 311, and the lower cross hinge joint 312 is symmetrically hinged to the lower part of the fixed seat 311.

[0026] To elaborate further, such as Figure 9 As shown, the clamp 432 consists of a valve body 4321, a guide rod 4322, and a clamping block 4323. The guide rod 4322 can extend and retract relative to the valve body 4321. The clamping block 4323 is fixed at the front end of the guide rod 4322. When the guide rod 4322 extends, it can drive the clamping block 4323 to clamp the drill rod, which facilitates the removal of the drill rod.

[0027] The functional principle of this invention can be explained through the following operation: In the early stage of operation, the bulldozer blade 2, which is hinged to the lower front end of the drilling rig body 1, takes the lead in site preparation. The blade of the bulldozer blade 2 is hinged to the drilling rig body 1. The two ends of the bulldozer blade cylinder are respectively hinged to the drilling rig body 1 and the blade. When the hydraulic system drives the bulldozer blade cylinder to extend and retract, it directly drives the blade to complete the lifting, tilting forward or backward movement around the hinge point, which can effectively complete the bulldozing and obstacle clearing operations in the construction area. After entering the formal support operation stage, the hydraulic system controls the bulldozer blade cylinder to lower the blade, so that the bulldozer blade 2 is completely in contact with the ground. The ground reaction force provides a stable support force for the drilling rig body 1. The reaction force generated by subsequent drilling and anchor cable advancement operations will be transmitted to the bulldozer blade 2 through the drilling rig body 1 and offset by the ground support force, avoiding the displacement of the drilling rig body 1 during operation, improving the overall stability of the equipment, and eliminating the need for additional auxiliary support structure arrangement, thus reducing construction preparation time. The rear articulation seat 31, fixed at the front end of the drilling rig body 1, serves as the linkage base for the boom assembly 3. The rear articulation seat 31 consists of a fixed seat 311, an upper cross-shaped hinge joint 313, and a lower cross-shaped hinge joint 312. The fixed seat 311 is rigidly connected to the drilling rig body 1. The upper cross-shaped hinge joint 313 is hinged above the fixed seat 311, and the lower cross-shaped hinge joint 312 is symmetrically hinged below the fixed seat 311. The two boom lifting cylinders 32 are respectively hinged at both ends to the rear articulation seat 31 and the telescopic boom 33, and are driven by a hydraulic system. When the boom lifting cylinder 32 extends or retracts, the difference in extension / retraction between the two boom lifting cylinders 32, utilizing the multi-directional hinged degrees of freedom of the cross-joint, causes the telescopic boom 33 to swing horizontally left and right around the rear hinge seat 31. The overall extension / retraction of the boom lifting cylinder 32, in turn, causes the telescopic boom 33 to rise or fall vertically, completing the basic spatial adjustment of the telescopic boom 33. The front end of the telescopic boom 33 is hinged to the front hinge seat 38, and the pitch cylinder 34, located between them, is hinged at both ends to the telescopic boom 33 and the front hinge seat 38, respectively. When the pitch cylinder 34 extends or retracts, it drives the front hinge seat 38 to complete the up-and-down pitching motion around the hinge point with the telescopic arm 33, adapting to the angle requirements of working holes at different heights. One end of the axial swing cylinder 37 fixed on the front hinge seat 38 is connected to the front hinge seat 38, and the other end is hinged to the front connecting seat 42 of the anchor bolt assembly 4. The extension and retraction of the axial swing cylinder 37 will drive the front connecting seat 42 and the entire anchor bolt assembly 4 to complete the axial rotation, realizing the fine adjustment of the working position. At the same time, the operating platform 35 fixed above the front hinge seat 38 provides the operator with control and operation space. The lifting platform 36 and the anchor bolt platform 39 arranged below its left and right ends provide support for manual auxiliary operation. The various types of cylinders and the hinge structure enable the working arm assembly 3 to have all-round multi-dimensional spatial adjustment capabilities, which can accurately position the anchor bolt assembly 4 to any working hole position, breaking through the drilling range limitation of traditional anchor bolt drilling rigs, realizing the construction planning of multiple anchor bolt holes in the surrounding area with one positioning, and improving positioning efficiency. The anchor bolt assembly 4 serves as the core operating mechanism. All components work in tandem around the front connecting seat 42 to complete the core processes of drilling and anchor cable advancement. The front connecting seat 42 is rigidly connected to the axial swing cylinder 37 and forms the installation base for the hydraulic anchor bolt drill 44, the anchor cable advancement assembly 43, and the lifting arm 41. After the working arm assembly 3 positions the anchor bolt assembly 4 to the working hole, the hydraulic system directly drives the hydraulic anchor bolt drill 44 to start, completing the anchor bolt drilling operation. The anchor cable advancement assembly 43 is installed above the hydraulic anchor bolt drill 44, and its clamp 432 consists of a valve body 4321 and a guide rod 4322. The clamping block 4323 is formed. The valve body 4321 is fixedly connected to the mounting plate 431 of the anchor cable propulsion assembly 43. The guide rod 4322 passes through the inside of the valve body 4321. During drilling, the hydraulic system drives the guide rod 4322 to extend along the axial direction of the valve body 4321, which drives the clamping block 4323 at the front end to clamp the drill rod, providing stable support for the drill rod and preventing the drill rod from shaking and affecting the drilling accuracy. After drilling is completed, the guide rod 4322 retracts and drives the clamping block 4323 to release, which can quickly cooperate with the hydraulic anchor drilling machine 44 to complete the disassembly and replacement of the drill rod, ensuring the continuity of drilling operations. After drilling is completed, the anchor cable propulsion assembly 43 initiates the anchor cable propulsion process. The active roller bracket 4341 and driven roller bracket 4342 of its anchor cable propeller 434 are hinged to the left and right sides of the mounting plate 431, respectively. The two ends of the rotating cylinder 4346 are hinged to the mounting plate 431 and the driven roller bracket 4342, respectively. The active roller bracket 4341 and the driven roller bracket 4342 are connected by a connecting rod 4345. When the hydraulic system drives the rotating cylinder 4346 to extend or retract, it causes the driven roller bracket 4342 to swing around the hinge point with the mounting plate 431. The connecting rod 4345 synchronously links with the active roller bracket 4341, realizing the movement of the active roller 4343 with the driven roller 4342. The flexible adjustment of the spacing between the driven wheels 4344 allows for the application of appropriate clamping force according to the size of different specifications of anchor cables, firmly clamping the anchor cable between the two wheels. Subsequently, the hydraulic motor drives the drive wheel 4343 on the drive roller bracket 4341 to rotate. Utilizing the friction between the drive wheel 4343 and the anchor cable, the anchor cable is moved forward, smoothly and accurately pushing the anchor cable into the drilled anchor hole. Meanwhile, the front top plate 433 at the front end of the anchor cable pushing assembly 43 guides and limits the anchor cable during the pushing process, preventing the anchor cable from deviating and ensuring the accuracy of the anchor cable installation. This allows for a seamless connection between the drilling and anchor cable installation processes, improving the efficiency of the support operation.

[0028] To meet the installation requirements of I-beams in roadway support, the lifting arm 41 of the anchor bolt assembly 4 works in conjunction with other components to complete the clamping, adjustment and lifting operations of the I-beams. The outer cylinder 411 of the lifting arm 41 is fixedly connected to the front connecting seat 42, and the inner cylinder 413 is inserted inside the outer cylinder 411. The two ends of the telescopic rod 412 are respectively hinged to the outer cylinder 411 and the inner cylinder 413. When the hydraulic system drives the telescopic rod 412 to extend and retract, it will drive the inner cylinder 413 to extend and retract along the axial direction of the outer cylinder 411, flexibly adjusting the overall length of the lifting arm 41 to adapt to different working distance requirements. The rotary reducer 414 fixed at the end of the inner cylinder 413 is connected to the gripper fixing plate 415. Several gripper plates 416 arranged above the gripper fixing plate 415 can open and close under hydraulic drive to quickly clamp the I-beam. When the hydraulic system drives the inner and outer rings of the rotary reducer 414 to rotate relative to each other, it will directly drive the gripper fixing plate 415 and the clamped I-beam to complete a 360° rotation in the left and right directions. It can flexibly avoid obstacles such as ventilation ducts and pipelines in the roadway during the lifting of the I-beam, solving the shortcomings of traditional anchor drilling rigs that do not have rotation adjustment for I-beam clamping and are easily blocked by roadway obstacles. The extension, rotation and lifting actions of the lifting arm 41 are precisely linked with the lifting, swinging and pitching actions of the working arm assembly 3. The hydraulic system coordinates and controls the action rhythm of each cylinder and rotary reducer to lift the I-beam smoothly and accurately to the designated support installation position, ensuring the installation efficiency and fit of the I-beam support.

[0029] After the construction of a single work position is completed, the hydraulic system does not need to drive the main body 1 of the drilling rig to move. It can drive the anchor bolt assembly 4 to complete the secondary precise positioning of the surrounding holes and support positions by simply adjusting the boom lifting cylinder 32, pitch cylinder 34 and axial swing cylinder 37 of the working arm assembly 3. This allows for direct commencement of subsequent operations, saving the time of equipment relocation and repositioning, effectively reducing the frequency of equipment replacement and the labor intensity of operators during construction. At the same time, it breaks through the limitations of the traditional anchor bolt drilling rig's narrow operating range and single function, improving the overall efficiency and operational stability of support construction in underground engineering such as mining and tunnel excavation, as well as slope support geotechnical engineering.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
