[0035] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Example

[0036] like Figure 1-10 As shown, the single-arm anchor drilling vehicle of the embodiment includes: Car body 100; Anchor drill rig 500, used for drilling holes in tunnel walls; A travel assembly 200 is disposed below the vehicle body 100 and is used to drive the vehicle body 100 to move; A variable amplitude adjustment arm 300, connected to the vehicle body 100, for adjusting the position of the anchor drill 500; The lifting and adjusting assembly 400 is disposed between the variable amplitude adjusting arm 300 and the anchor drilling rig 500 , and the lifting and adjusting assembly 400 is used for secondary adjustment of the working height of the anchor drilling rig 500 .

[0037] Through such a design, a lifting and adjusting assembly 400 is arranged between the anchor drilling rig 500 and the variable amplitude adjustment arm 300. The lifting and adjusting assembly 400 can adjust the working height of the anchor drilling rig 500 for a second time, thereby avoiding the interference of the belt with the variable amplitude adjustment arm 300 when the anchor drilling rig 500 works across the belt, thereby preventing the anchor drilling rig 500 from drilling holes in low places; the variable amplitude adjustment arm 300 is a telescopic arm commonly seen on the market.

[0038] Specifically, the lifting and adjusting assembly 400 includes at least two mounting plates 410, a plurality of guide columns 420 fixedly disposed between the mounting plates 410, and a drill mounting seat 430 slidably connected to the guide columns 420. The anchor drilling rig 500 is connected to the drill mounting seat 430, and the sliding direction of the drill mounting seat 430 is parallel to the axial direction of the guide columns 420. A drill driving assembly 440 for driving the drill mounting seat 430 to slide is disposed between the drill mounting seat 430 and the mounting plate 410.

[0039] With such a design, the drilling rig driving assembly 440 drives the drilling rig mounting seat 430 to rise and fall, thereby driving the anchor drilling rig 500 on the drilling rig mounting seat 430 to rise and fall, thereby achieving the purpose of adjusting the height of the anchor drilling rig 500.

[0040] Furthermore, a height adjustment component for adjusting the height of the mounting plate 410 is provided between the mounting plate 410 and the amplitude adjustment arm 300 .

[0041] With such a design, the height of the anchor drilling machine 500 can be adjusted by adjusting the height of the lifting and adjusting assembly 400 .

[0042] Specifically, the height adjustment assembly includes an adjustment arm mounting seat 450 slidably connected to the guide column 420 , an adjustment arm driving assembly 460 driving the height of the adjustment arm mounting seat 450 , and the amplitude adjustment arm 300 is connected to the adjustment arm mounting seat 450 .

[0043] With such a design, since the adjusting arm mounting seat 450 is connected to the variable amplitude adjusting arm 300, when the adjusting arm driving assembly 460 is working, the adjusting arm mounting seat 450 and the variable amplitude adjusting arm 300 are relatively stationary, and the mounting plate 410 changes in height, thereby driving the height change of the anchor drilling rig 500.

[0044] Furthermore, a drilling rig angle adjustment component 510 for adjusting the drilling angle of the anchor drilling rig 500 is provided between the drilling rig mounting seat 430 and the anchor drilling rig 500 .

[0045] Through such a design, the operating angle of the anchor drilling rig 500 is guaranteed.

[0046] Specifically, the drilling rig angle adjustment assembly 510 includes a drilling rig swing cylinder and a drilling rig rotation cylinder.

[0047] With such a design, the angle of the anchor drill 500 can be adjusted in all directions in coordination with the rotation of the variable amplitude adjustment arm 300 .

[0048] Furthermore, a standing platform 431 is rotatably provided on the side wall of the drilling rig mounting seat 430, and the standing platform 431 has two working positions. In the first working position, the standing surface of the standing platform 431 is vertically arranged in a storage state; in the second working position, the standing surface of the standing platform 431 is horizontally arranged in a use state.

[0049] Through such a design, the utilization rate of the lifting and adjusting component 400 is improved and the application range is wide.

[0050] Furthermore, the mounting plate 410 is provided with a supporting assembly, and the supporting assembly is used to fix the position of the lifting and adjusting assembly 400 when the anchor drilling machine 500 is working.

[0051] Through such a design, when the anchor drilling machine 500 is working, the support assembly can ensure the stability of the lifting and adjusting assembly 400, thereby ensuring the working stability of the anchor drilling machine 500.

[0053] With such a design, the tightening seat adjustment assembly drives the upper tightening seat 471 to rise and the lower tightening seat 472 to descend, respectively, to abut against the top and bottom of the lane, thereby achieving the purpose of fixing the position of the lifting and lowering adjustment assembly 400.

[0055] Through such a design, the purpose of driving the upper tightening seat 471 and the lower tightening seat 472 to rise and fall is achieved.

[0056] Furthermore, the upper tightening seat 471 and the lower tightening seat 472 are both provided with a tightening protrusion 475 .

[0057] With such a design, the upper tightening seat 471 and the lower tightening seat 472 are tightened more firmly against the top and bottom of the lane.

[0058] Specifically, the two mounting plates 410 are respectively fixed to the two ends of the cylinder body of the upper supporting cylinder 473 , and the cylinder body of the lower supporting cylinder 474 is fixedly connected to the cylinder body of the upper supporting cylinder 473 .

[0059] With such a design, the cylinder body of the upper supporting oil cylinder 473 is used as a connecting piece between the two mounting plates 410, and the structure is compact.

[0060] Furthermore, the drilling rig drive assembly 440 includes a double-speed drive assembly, which includes a drilling rig cylinder 441, a sprocket group 442 and a chain group 443. The sprocket group 442 is connected to the cylinder body of the drilling rig cylinder 441, and two groups of chain groups 443 are arranged on both sides of the cylinder body of the drilling rig cylinder 441. The piston rod of the drilling rig cylinder 441 is fixedly connected to the mounting plate 410; the chain group 443 is provided with a fixed chain 4431, and the fixed chain 4431 is fixedly connected to the cylinder body of the upper support cylinder 473. The drilling rig mounting seat 430 is connected to the chain group 443.

[0061] With such a design, the one-fold extension and retraction stroke of the drilling rig oil cylinder 441 can make the stroke of the drilling rig mounting seat 430 double (one-fold stroke brought by the extension and retraction of the drilling rig oil cylinder 441 + one-fold stroke brought by the movement of the chain assembly 443).

[0062] Furthermore, the adjusting arm driving assembly 460 includes a stroke amplification assembly, and the structure of the stroke amplification assembly is similar to that of the speed-multiplying driving assembly, which will not be described in detail here.

[0063] Through such a design, the moving range of the adjustment arm driving assembly 460 is expanded.

[0064] Furthermore, a mounting seat adjustment component 310 for adjusting the position of the adjusting arm mounting seat 450 is provided between the adjusting arm mounting seat 450 and the amplitude adjustment arm 300 .

[0065] Through such a design, the purpose of adjusting the working position of the lifting adjustment component 400 is achieved.

[0066] Specifically, the mounting seat adjustment assembly 310 includes a mounting seat swing cylinder and a mounting seat rotation cylinder. The mounting seat swing cylinder and the mounting seat rotation cylinder are both common cylinder installation structures on the market and will not be described in detail herein.

[0067] Specifically, the walking component 200 includes two sets of track assemblies 210 connected to the vehicle body 100, and the track assembly 210 includes a track frame 211, a driving wheel 212 and a guide wheel 213 respectively arranged at both ends of the track frame 211, and a track group 214 sleeved outside the driving wheel 212 and the guide wheel 213; a plurality of supporting rollers 215 are rotatably arranged below the track frame 211, and the track group 214 and the supporting rollers 215 are in rolling cooperation.

[0068] This design ensures the stability of the drilling vehicle when traveling in the tunnel.

[0069] Furthermore, the track assembly 210 is slidably connected to the vehicle body 100 , and the sliding direction of the track assembly 210 is parallel to the width direction of the vehicle body 100 .

[0070] With such a design, when the drilling vehicle is being transported or passing through narrow passages, the track assembly 210 can be retracted inward to be consistent with the width of the vehicle body 100, which facilitates the transportation and passage of the drilling vehicle; when working in a wider tunnel or the anchor drilling rig 500, the two sets of track assemblies 210 can be unfolded to improve stability.

[0071] Specifically, a support sleeve 110 is fixedly provided at the bottom of the vehicle body 100, and a cylinder seat 220 is fixedly provided on the track frame 211, which is penetrated through the support sleeve 110 and slidably connected to the support sleeve 110, and a widening cylinder 230 is provided in the cylinder seat 220, and the cylinder body of the widening cylinder 230 is fixedly connected to the support sleeve 110, and the piston rod of the widening cylinder 230 is fixedly connected to the cylinder seat 220.

[0072] Through such a design, the purpose of driving the crawler track assembly 210 to slide is achieved.

[0073] Furthermore, a wear-resistant strip 221 is fixedly provided on the contact surface between the cylinder seat 220 and the support sleeve 110 .

[0074] Through such a design, the service life of the cylinder seat 220 is increased.

[0075] Furthermore, a tensioning assembly for tightening the track set 214 is provided between the guide wheel 213 and the track frame 211 .

[0076] Such a design improves the stability of the track assembly 214 during use.

[0077] Specifically, the tensioning assembly includes a guide rail 241 fixedly connected to the track frame 211, and a wheel seat 242 slidably connected to the guide rail 241, the guide wheel 213 is rotatably connected to the wheel seat 242, the extension direction of the guide rail 241 is horizontally arranged, and a force-applying assembly is arranged between the track frame 211 and the wheel seat 242 for applying force to the wheel seat 242 in a direction away from the driving wheel 212.

[0078] Through such a design, the purpose of tightening the track assembly 214 is achieved.

[0079] Specifically, the force-applying assembly includes a compression spring 243 , one end of which is fixedly connected to the track frame 211 , and the other end of the compression spring 243 is fixedly provided with a push plate 244 , which is abutted against the wheel seat 242 , and the push plate 244 is slidably connected to the guide rail 241 .

[0080] Specifically, the vehicle body 100 is provided with a lifting leg 120, and the lifting leg 120 is used to lift the vehicle body 100 when the track assembly 210 is widened or retracted.

[0081] With such a design, when the track assembly 210 needs to expand outward or retract inward, in order to improve the smoothness of sliding of the track assembly 210 , the lifting legs 120 lift the vehicle body 100 , and the track assembly 210 is separated from the ground, thereby reducing the sliding friction of the track assembly 210 .

[0082] Specific usage of the embodiment: When the single-arm anchor drilling vehicle is being transported or passing through a narrow passage, the lifting legs 120 are lowered to lift the vehicle body 100 so that the track assembly 210 is off the ground, the piston rod of the widening cylinder 230 is retracted, and the two sets of track assemblies 210 are close to each other until they are the same width as the vehicle body 100, the lifting legs 120 are retracted, and the track assembly 210 is in contact with the ground, so that the vehicle can be transported or pass through a narrow passage smoothly; When the single-arm anchor drilling vehicle is moving or the anchor drilling rig 500 is operating, the lifting legs 120 descend to lift the vehicle body 100 so that the track assembly 210 is off the ground, the piston rod of the widening cylinder 230 is extended, the two sets of track assemblies 210 move away from each other, the lifting legs 120 shrink, and the track assembly 210 contacts the ground. At this time, the track assembly 210 protrudes from the vehicle body 100, thereby improving the stability of the single-arm anchor drilling vehicle.

[0083] When the anchor drill rig 500 is operating across the belt: the variable amplitude adjustment arm 300 pushes the lifting adjustment assembly 400 to the other side of the belt, the mounting seat adjustment assembly 310 adjusts the lifting adjustment assembly 400 to a vertical state, the upper support cylinder 473 drives the upper tightening seat 471 to rise and abut against the top of the roadway, and the lower support cylinder 474 drives the lower tightening seat 472 to descend and abut against the bottom of the roadway. At this time, the lifting adjustment assembly 400 is fixed in position; The drilling rig angle adjustment assembly 510 adjusts the anchor drilling rig 500 to a horizontal drilling state. According to the required drilling height, the drilling rig drive assembly 440 adjusts the height of the drilling rig mounting seat 430 to adjust the height of the anchor drilling rig 500.

[0084] The piston rod of the drilling rig cylinder 441 extends out, and the cylinder body of the drilling rig cylinder 441 rises. Since the fixed chain 4431 is fixed to the cylinder body of the upper support cylinder 473, as the cylinder body of the drilling rig cylinder 441 rises, the chain group 443 rotates, thereby driving the drilling rig mounting seat 430 connected to the chain group 443 to rise. The rising stroke of the drilling rig mounting seat 430 = the rising stroke of the cylinder body of the drilling rig cylinder 441 + the moving stroke of the chain group 443, that is, the rising stroke of the drilling rig mounting seat 430 is twice the extending stroke of the piston rod of the drilling rig cylinder 441.

[0085] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
