Description

Technical Field

[0001] The invention relates to tunnel construction equipment, in particular to a chiseling and drilling machine. Background Art

[0002] During the tunnel construction process, the secondary lining concrete needs to be roughened to improve the adhesion of the concrete surface and ensure that the construction surfaces of the two construction stages are firmly bonded. At present, the main methods of tunnel roughening are manual roughening, airborne roughening machine roughening and tunnel-specific roughening machine roughening. Manual roughening mainly involves workers using small handheld roughening machines or electric picks (or hydraulic picks) for roughening. This roughening method is inefficient, labor-intensive and cannot guarantee the quality of roughening. Substandard roughening quality will lead to loose adhesion between the two construction surfaces, water seepage or cracking. Airborne roughening machines are generally installed on excavators or simple trusses for roughening. Due to the limited space in the tunnel, this construction method will affect the entry and exit of other tunnel construction machinery. The roughening part of the existing tunnel-specific roughening machine is generally matched with a certain size of tunnel lining curved surface. This roughening machine has a good roughening effect when used for roughening tunnels of this size, but when used for roughening tunnels of other sizes, the roughening part and the tunnel curved surface do not match, resulting in the problem of substandard roughening quality. Therefore, different-sized tunnels must be equipped with a corresponding-sized chiseling machine, which greatly increases the cost of tunnel construction. Since the tunnel surface to be chiseled has a certain longitudinal offset, or the chiseling machine is offset when moving longitudinally, it is no longer parallel to the tunnel surface to be chiseled, and the chiseling effect cannot be guaranteed at this time. In addition, chiseling tools such as chiseling units, electric picks and hydraulic picks are required to be as perpendicular to the working surface as possible. The side wall of the tunnel is a curved surface. When the chiseling tool moves up and down along the curved surface with the manipulator, the stability is poor and it is not conducive to maintaining perpendicularity to the working surface.

[0003] The drilling construction of the reinforcing steel bar fixing holes on the side of the ditch cable trough and the roughening construction of the low side walls of the tunnel are both preparatory steps before pouring the ditch cable trough. Most of them adopt manual processes, which have large workload, high labor intensity, very low construction efficiency and uneven construction quality. Summary of the invention

When the tunnel surface 4 to be chiseled has a certain offset in the longitudinal direction, or the chiseling and drilling machine base 1 is offset when moving in the longitudinal direction so that it is no longer parallel to the tunnel surface 4 to be chiseled, the chiseling unit 2 can be driven to swing forward and backward by the forward and backward swing driving member 34, so as to correct the non-parallel angle between the base 1 and the surface 4 to be chiseled in the longitudinal direction, which is conducive to ensuring the chiseling quality; the second mechanical arm 5 is provided with a drilling unit 6, which can alternately perform drilling construction during the chiseling construction, and is particularly suitable for chiseling the short side walls of the tunnel and the construction of reinforcing steel bar fixing holes on the side of the ditch cable trough before pouring the tunnel ditch cable trough. By completing two time-consuming and labor-intensive processes with one device, the construction efficiency is greatly improved, the labor intensity is greatly reduced, and the construction quality is stable and controllable.

[0024] As a preferred technical solution, in this embodiment, the front and rear swing driving member 34 is a telescopic structure and is provided with two pieces, and the two front and rear swing driving members 34 are respectively provided at the front and rear sides of the hair cutting unit 2. Figure 2As shown, when the haircutting unit 2 needs to swing backward, the front-rear swing driving member 34 on the rear side retracts and the front-rear swing driving member 34 on the front side extends, which can effectively correct the non-parallel angle between the base 1 and the surface 4 to be haircutted in the longitudinal direction, and at the same time, the haircutting unit 2 is reliably pressed against the surface 4 to be haircutted, and the stability of the haircutting unit 2 on the first mechanical arm 3 is ensured. The front-rear swing driving member 34 can be, for example, a cylinder, a spring strut or an air spring.

[0025] Furthermore, in this embodiment, the first mechanical arm 3 includes a first horizontal telescopic arm 31 provided on the base 1, a swing arm 32 hinged to the first horizontal telescopic arm 31, and an up-down swing driving member 33 for driving the swing arm 32 to swing up and down, the haircutting unit 2 is hinged to the swing arm 32, and a front-back swing driving member 34 is provided on the swing arm 32.

[0026] Furthermore, in this embodiment, the first horizontal telescopic arm 31 includes a first outer box 311 disposed on the base 1, a first inner box 312 disposed in the first outer box 311, and a first telescopic driving member 313 for driving the first inner box 312 to telescope horizontally, the swing arm 32 is hinged to the first inner box 312, and the up-and-down swing driving member 33 is connected between the first inner box 312 and the swing arm 32. When in use, the first telescopic driving member 313 drives the first inner box 312 to telescope horizontally relative to the first outer box 311, the first inner box 312 drives the up-and-down swing driving member 33, the swing arm 32, and the haircutting unit 2 to move horizontally as a whole, and the up-and-down swing driving member 33 drives the swing arm 32 and the haircutting unit 2 to swing up and down as a whole to adjust the angle of the haircutting unit 2 to be nearly perpendicular to the working curved surface 6, so as to ensure the haircutting quality. As a preferred technical solution, the swing arm 32 can also be an inner first outer box structure to achieve telescoping, so as to facilitate fine-tuning the distance between the haircutting unit 2 and the surface 4 to be haircutted.

[0027] Furthermore, in this embodiment, the up-down swing driving member 33 and the front-back swing driving member 34 are telescopic oil cylinders, the swing arm 32 is a bent structure and is hinged to the first inner box 312 at the bend, one end of the up-down swing driving member 33 is hinged to the first inner box 312, the other end of the up-down swing driving member 33 is hinged to one end of the swing arm 32, and the two ends of the front-back swing driving member 34 are respectively hinged to the other end of the swing arm 32 and the haircutting unit 2. As a preferred technical solution, the up-down swing driving member 33 and the front-back swing driving member 34 use oil cylinders with articulated bearing hanging earrings to ensure that the swing arm 32 and the haircutting unit 2 form a universal hinge structure, so that the vertical swing (i.e., up-down swing) and lateral swing (i.e., front-back swing) of the haircutting unit 2 can be flexibly adjusted to make it always perpendicular to the surface to be haircutted.

[0028] Furthermore, in this embodiment, the chiseling unit 2 includes a swing seat 21, a chiseling component 23 and two groups of limiting rollers 22. The swing seat 21 is hinged to the first mechanical arm 3. The chiseling component 23 and the limiting rollers 22 are arranged on the swing seat 21. The two groups of limiting rollers 22 are arranged on the front and rear sides of the chiseling component 23, and the limiting rollers 22 in the same group are arranged on the upper and lower sides of the chiseling component 23. When working, the swing seat 21 and the chiseling component 23 and the limiting rollers 22 thereon are driven by the up and down swing driving member 33 to swing up and down, and the swing seat 21 is provided with limiting rollers 22 on both the front and rear sides and the upper and lower sides. The swing seat 21 can adjust the up and down swing angle according to the curvature of the surface 4 to be chiseled, and the limiting rollers 22 are used to prevent the chiseling component 23 from being damaged, and to maintain the stability of the swing seat 21 and the chiseling component 23 during the construction process. The chiseling component 23 can be, for example, a pneumatic chiseling machine, an electric pick or a hydraulic pick.

[0029] As a preferred technical solution, in this embodiment, the chiseling component 23 is arranged along the perpendicular midline of the line connecting the center points of the upper and lower limiting rollers 22, which is beneficial to improving the stability of the chiseling component 23 during the construction process and ensuring that the chiseling component 23 has a certain impact stroke.

[0030] As a preferred technical solution, in this embodiment, along the vertical direction, the hinge of the front and rear swing driving member 34 and the swing seat 21 is located between the upper and lower limit rollers 22; and along the left and right direction, the hinge of the front and rear swing driving member 34 and the swing seat 21 is located between the line connecting the center points of the upper and lower limit rollers 22 and the surface to be roughened 4. This is conducive to ensuring that the front and rear swing driving member 34 can always provide a stable pressing force, so that the limit roller 22 is always close to the surface to be roughened 4, and the possibility of the roughening member 23 overturning is reduced.

[0031] Furthermore, in this embodiment, the base 1 is provided with walking wheels 11 and guide rails 12 arranged along the front-to-back direction, the guide rails 12 are provided with a sliding seat 13, the sliding seat 13 is provided with a rotating seat 14, and the first robotic arm 3 and the second robotic arm 5 are provided on the rotating seat 14. The base 1 can drive the guide rail 12, the sliding seat 13, the rotating seat 14, the first mechanical arm 3, the second mechanical arm 5, etc. to move forward and backward as a whole. When the sliding seat 13 slides along the guide rail 12, it can drive the rotating seat 14, the first mechanical arm 3, the second mechanical arm 5, etc. to move forward and backward as a whole. When the base 1 reaches the construction position, the roughening unit 2 and the drilling unit 5 can cover a larger working surface in the longitudinal direction, and can realize single-station continuous operation, that is, the construction distance of one-time in-place is greatly increased, simplifying the construction process; the base 1 moves forward and backward times; the rotating seat 14 can drive the first mechanical arm 3, the second mechanical arm 5 and the roughening unit 2 to rotate, so that the roughening and drilling can be constructed on both sides of the base 1, or at any angle, and it is also convenient to change direction in the narrow space of the tunnel, and to construct the roughening surface 4 on the other side of the tunnel, which is more convenient and flexible to use. Of course, in other embodiments, the base 1 can also be a non-powered frame, with only the sliding seat 13 moving forward and backward, or a crawler structure can be used to realize forward and backward walking. The sliding seat 13 and the base 1 can slide forward and backward by using a gear rack pair, a sprocket chain pair, etc. Generally speaking, after the roughing is completed, the telescopic arm is rotated to rotate the drilling unit about 180° to the position to be drilled. If the tunnel is narrow, during normal roughing, the drilling unit can be moved to the other side above the position to be drilled, so roughing and drilling can be done at the same time.

[0032] Furthermore, in this embodiment, the second mechanical arm 5 includes a second horizontal telescopic arm 51 disposed on the base 1, and a vertical telescopic arm 52 connected to the second horizontal telescopic arm 51. The telescopic direction of the second horizontal telescopic arm 51 is opposite to the telescopic direction of the first horizontal telescopic arm 31, and the drilling unit 6 is disposed on the vertical telescopic arm 52. During operation, the second horizontal telescopic arm 51 drives the vertical telescopic arm 52 and the drilling unit 6 to telescope horizontally to the top of the construction position, and then the vertical telescopic arm 52 extends downward to press the drilling unit 6 so that the drilling unit 6 completes the drilling construction, and the structure is simple and reliable. Among them, the drilling unit 6 can include a single or multiple impact drills, etc. When multiple are used, the vertical telescopic arms 52 can be set to drive the lifting and lowering respectively, or the single vertical telescopic arm 52 can drive the overall lifting and lowering.

[0033] Furthermore, in this embodiment, the second horizontal telescopic arm 51 includes a second outer box 511 disposed on the base 1, a second inner box 512 disposed in the second outer box 511, and a second telescopic driving member 513 for driving the second inner box 512 to telescope horizontally, and the vertical telescopic arm 52 includes a third outer box 521 connected to the second inner box 512, a third inner box 522 disposed in the third outer box 521, and a third telescopic driving member 523 for driving the third inner box 522 to telescope vertically, and the drilling unit 6 is disposed on the third inner box 522. The structures of the second horizontal telescopic arm 51 and the vertical telescopic arm 52 are substantially the same as those of the first horizontal telescopic arm 31, and are not described in detail.
