[0032] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Example

[0033] As Figure 1-10 shown, the walking assembly of the anchor rod drill carriage of the embodiment comprises:

[0034] a vehicle body 100;

[0035] an anchor rod drilling machine 500 for drilling operation on the roadway wall;

[0036] a walking assembly 200 arranged below the vehicle body 100 for driving the vehicle body 100 to move;

[0037] an amplitude adjusting arm 300 arranged in connection with the vehicle body 100 for adjusting the position of the anchor rod drilling machine 500;

[0038] a lifting adjusting assembly 400 arranged between the amplitude adjusting arm 300 and the anchor rod drilling machine 500, the lifting adjusting assembly 400 being used for secondary adjustment of the working height of the anchor rod drilling machine 500.

[0039] Through such design, the lifting adjusting assembly 400 is arranged between the anchor rod drilling machine 500 and the amplitude adjusting arm 300, the lifting adjusting assembly 400 can secondarily adjust the working height of the anchor rod drilling machine 500, avoiding the interference of the belt on the amplitude adjusting arm 300 when the anchor rod drilling machine 500 is working across the belt, and thus avoiding the anchor rod drilling machine 500 from being unable to drill the anchor rod hole at low place. The amplitude adjusting arm 300 is a common telescopic arm in the market.

[0040] Specifically, the lifting adjusting assembly 400 comprises at least two mounting plates 410, a plurality of guide columns 420 fixedly arranged between the mounting plates 410, a drilling machine mounting seat 430 in sliding connection with the guide columns 420, the anchor rod drilling machine 500 being arranged in connection with the drilling machine mounting seat 430, the sliding direction of the drilling machine mounting seat 430 being parallel to the axial line direction of the guide columns 420, and a drilling machine driving assembly 440 being arranged between the drilling machine mounting seat 430 and the mounting plates 410 for driving the drilling machine mounting seat 430 to slide.

[0041] Through such design, the drilling machine driving assembly 440 drives the drilling machine mounting seat 430 to lift or lower, thereby driving the anchor rod drilling machine 500 on the drilling machine mounting seat 430 to lift or lower, and thus achieving the purpose of height adjustment of the anchor rod drilling machine 500.

[0042] Further, a height adjusting assembly for adjusting the height of the mounting plate 410 is arranged between the mounting plate 410 and the amplitude adjusting arm 300.

[0043] Through such design, the height of the anchor rod drilling machine 500 can be adjusted by adjusting the height of the lifting adjusting assembly 400.

[0044] 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 .

[0045] Through 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.

[0046] 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 .

[0047] Through such a design, the operating angle of the anchor drilling rig 500 is guaranteed.

[0048] Specifically, the drilling rig angle adjustment assembly 510 includes a drilling rig swing cylinder and a drilling rig rotation cylinder.

[0049] With this design, the angle of the anchor drill rig 500 can be adjusted in all directions in coordination with the rotation of the luffing adjustment arm 300 .

[0050] 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.

[0051] With such a design, the utilization rate of the lifting and adjusting component 400 is improved, and the scope of application is wide.

[0052] Furthermore, the mounting plate 410 is provided with a support assembly, and the support assembly is used to fix the position of the lifting and adjusting assembly 400 when the anchor drilling machine 500 is working.

[0053] With 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.

[0054] Specifically, the support assembly includes an upper tightening seat 471 and a lower tightening seat 472 , and a tightening seat adjustment assembly for adjusting the height of the upper tightening seat 471 and the lower tightening seat 472 is provided between the upper tightening seat 471 and the lower tightening seat 472 and the mounting plate 410 .

[0055] Through 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, and counteracts the top and bottom of the tunnel, thereby achieving the purpose of fixing the position of the lifting adjustment assembly 400.

[0056] Specifically, the tightening seat adjustment assembly includes an upper support cylinder 473 and a lower support cylinder 474 connected to the mounting plate 410. The upper support cylinder 473 is used to drive the upper tightening seat 471 to rise and fall, and the lower support cylinder 474 is used to drive the lower tightening seat 472 to rise and fall.

[0057] 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.

[0058] Furthermore, both the upper tightening seat 471 and the lower tightening seat 472 are provided with a tightening protrusion 475 .

[0059] 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 tunnel.

[0060] 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 .

[0061] 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, resulting in a compact structure.

[0062] 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 the two groups of chain groups 443 are respectively 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.

[0063] With this design, the double stroke of the drilling cylinder 441 can make the stroke of the drilling mounting base 430 double (double the stroke caused by the extension and contraction of the drilling cylinder 441 + double the stroke caused by the movement of the chain assembly 443).

[0064] Furthermore, the regulating arm driving assembly 460 includes a stroke amplification assembly, and the structure of the stroke amplification assembly is similar to that of the speed-doubling driving assembly, which will not be described in detail here.

[0065] With such a design, the moving range of the adjustment arm driving assembly 460 is expanded.

[0066] 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 .

[0067] Through such a design, the purpose of adjusting the working position of the lifting adjustment component 400 is achieved.

[0068] Specifically, the mounting seat adjustment assembly 310 includes a mounting seat swing cylinder and a mounting seat rotary cylinder. The mounting seat swing cylinder and the mounting seat rotary cylinder are both common cylinder mounting structures on the market and will not be described in detail here.

[0069] 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 arranged 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 rolls with the supporting rollers 215.

[0070] This design ensures the stability of the drilling vehicle when traveling in the tunnel.

[0071] 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 .

[0072] With this 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 when the anchor drilling rig 500 is working, the two sets of track assemblies 210 can be unfolded to improve stability.

[0073] 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 passed through the support sleeve 110 and is slidably connected to the support sleeve 110. 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.

[0074] Through such a design, the purpose of driving the crawler track assembly 210 to slide is achieved.

[0075] Furthermore, a wear-resistant strip 221 is fixedly provided on the contact surface between the cylinder seat 220 and the support sleeve 110 .

[0076] With such a design, the service life of the cylinder seat 220 is increased.

[0077] Furthermore, a tensioning assembly for tightening the track assembly 214 is provided between the guide wheel 213 and the track frame 211 .

[0078] This design improves the stability of the track assembly 214 during use.

[0079] Specifically, the tensioning assembly includes a guide rail 241 fixedly connected to the track frame 211, a wheel seat 242 slidingly 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 provided between the track frame 211 and the wheel seat 242 for applying force to the wheel seat 242 away from the driving wheel 212.

[0080] Through such a design, the purpose of tightening the track assembly 214 is achieved.

[0081] 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 arranged in contact with the wheel seat 242 , and the push plate 244 is slidably connected to the guide rail 241 .

[0082] Specifically, the vehicle body 100 is provided with lifting legs 120 , and the lifting legs 120 are used to lift the vehicle body 100 when the track assembly 210 is widened or retracted.

[0083] With this design, when the track assembly 210 needs to expand outward or retract inward, in order to improve the smoothness of the 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.

[0084] Specific usage of the embodiment:

[0085] When the anchor drilling vehicle is transported or passes through a narrow passage using the traveling assembly, 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 brought closer 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 passed through a narrow passage smoothly.

[0086] When the anchor rod drilling rig 500 is working, the lifting legs 120 are lowered to lift the vehicle body 100, the piston rods of the spreader cylinders 230 are extended, the two groups of track assemblies 210 are away from each other, the lifting legs 120 are contracted, the track assemblies 210 are in contact with the ground, and the track assemblies 210 protrude out of the vehicle body 100, thereby improving the stability of the anchor rod drilling rig 500.

[0087] When the anchor rod drilling rig 500 is working on the belt, the luffing adjusting arm 300 pushes the lifting adjusting assembly 400 to the other side of the belt, the mounting seat adjusting assembly 310 adjusts the lifting adjusting assembly 400 to be in a vertical state, the upper support cylinder 473 drives the upper clamping seat 471 to ascend and abut against the top of the roadway, the lower support cylinder 474 drives the lower clamping seat 472 to descend and abut against the bottom of the roadway, and the position of the lifting adjusting assembly 400 is fixed.

[0088] The drill angle adjusting assembly 510 adjusts the anchor rod drilling rig 500 to be in a horizontal drilling state, and the drill driving assembly 440 adjusts the height of the drill mounting seat 430, thereby adjusting the height of the anchor rod drilling rig 500 according to the height of the drilling hole.

[0089] The piston rod of the drill cylinder 441 is extended, the cylinder body of the drill cylinder 441 is lifted, the chain set 443 is rotated due to the fixing of the chain 4431 and the cylinder body of the upper support cylinder 473, the drill mounting seat 430 connected with the chain set 443 is lifted, and the lifting stroke of the drill mounting seat 430 is equal to the lifting stroke of the cylinder body of the drill cylinder 441 plus the moving stroke of the chain set 443, that is, the lifting stroke of the drill mounting seat 430 is twice the extension stroke of the piston rod of the drill cylinder 441.

[0090] The above only describes the preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, some improvements and decorations can be made, and these improvements and decorations should also be considered as the protection scope of the present application.
