Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The core of this invention is to provide a tunnel laser drilling device that can effectively improve drilling efficiency and reduce drilling labor intensity.

[0030] Please refer to Figures 1-7 ,in, Figure 1 This is a schematic diagram of the tunnel laser drilling device provided by the present invention; Figure 2 for Figure 1 Side view; Figure 3 This is a schematic diagram of the auxiliary arm drilling device;

[0031] Figure 4 This is a schematic diagram of the top drilling device; Figure 5 This is an assembly diagram of the first positioning device and the second positioning device. Figure 6 This is a schematic diagram of the second positioning device; Figure 7 This is a schematic diagram of the first positioning device.

[0032] This specific embodiment provides a tunnel laser drilling device, including: a first positioning device 4 for laser positioning of the top hole, a second positioning device 2 for laser positioning of the side wall hole, an auxiliary arm drilling device 3, a work platform 1 for rotation and lifting movements, and a control device. The auxiliary arm drilling device 3 is used to perform drilling operations on the top hole and the side wall hole. The first positioning device 4, the second positioning device 2, the auxiliary arm drilling device 3, and the work platform 1 are all connected to the control device.

[0033] It should be noted that the drilling is first positioned using a laser emitting device. Then, the construction worker stands on the work platform 1 to perform the drilling operation. This enables automatic hole positioning, increases drilling speed, assists manual drilling, reduces the labor intensity of operators, and improves the construction environment. In practical applications, the shape, structure, size, and position of the first positioning device 4, the second positioning device 2, the auxiliary arm drilling device 3, the work platform 1, and the control device can be determined according to actual conditions and needs.

[0034] When using the tunnel laser drilling device provided by this invention, when drilling a sidewall hole is required, the second positioning device 2 can be used to laser-position the sidewall hole. Then, the control device's working platform 1 is rotated or raised to move the operator to the sidewall hole position. Finally, the operator controls the auxiliary arm drilling device 3 to drill the positioned sidewall hole. When drilling a top hole is required, the first positioning device 4 can be used to laser-position the top hole. Then, the control device's working platform 1 is rotated or raised to move the operator to the top hole position. Finally, the operator controls the auxiliary arm drilling device 3 to drill the positioned top hole. Therefore, this device can achieve rapid and accurate positioning and drilling operations, and also helps to reduce the labor intensity of operators.

[0035] In summary, the tunnel laser drilling device provided by this invention can effectively improve drilling efficiency and reduce drilling labor intensity.

[0036] Based on the above embodiments, preferably, the auxiliary arm drilling device 3 includes a column 31, a first arm 32 horizontally disposed on one side of the column 31, a side drilling device 33 for drilling side wall holes, a balancer 34, a second arm 35 vertically distributed with the first arm 32, and a top drilling device 36 for drilling top holes. The side drilling device 33 is suspended on the second arm 35 by the balancer 34.

[0037] It should be noted that when using this device for tunnel drilling, the auxiliary arm drilling device 3 can be mounted on the flatbed truck 11, while the operator stands on the work platform 1. When drilling a side wall hole, the side drilling device 33 connected to the first arm 32, the second arm 35, and the balancer 34 is swung, and the side drilling device 33 is manually operated to drill. When drilling a top hole, the first arm 32, the second arm 35, and the top drilling device 36 are swung, and the top drilling device 36 is manually operated to drill.

[0038] Preferably, the side drilling device 33 includes an electric hammer device and a dust collection device for absorbing dust generated during drilling. The dust collection device includes a dust collection hood that can be fitted onto the drilling working surface and surround the hole to be drilled. When the drill rod of the electric hammer device drills, the dust generated in this process can be sucked into the dust collection device through the dust collection hood, thereby improving the drilling working environment.

[0039] Preferably, the top drilling device 36 includes a feed cylinder 361, a handle 362, a guide wheel frame 363, vertically distributed guide grooves 364, and an electric hammer dust collection device 365. The electric hammer dust collection device 365 is slidably suspended on the second arm 35 via the guide wheel frame 363, and the feed cylinder 361 is used to drive the electric hammer dust collection device 365 to slide along the guide groove 364.

[0040] It should be noted that the guide wheel frame 363 can move freely on the second arm 35, and the balancer 34 enables the lower side drilling device 33 to be in a weightless state. Only a very small external force is needed to displace the side drilling device 33, achieving precise positioning. When top hole drilling is required, the first arm 32, the second arm 35, and the top drilling device 36 can be swung to align the electric hammer dust collector 365 with the position of the top drilling hole, and the electric hammer dust collector 365 and the feed cylinder 361 can be controlled to perform drilling operations. The top drilling device 36 can move freely on the second arm 35 via the guide wheel frame 363. The operator holds the handle 362 to control the electric hammer dust collector 365 to rotate around the ball joint 9 for precise positioning.

[0041] Preferably, the column 31 includes at least two telescopic arms and at least one telescopic cylinder, with the telescopic cylinder positioned between two adjacent telescopic arms. For example, the column 31 may consist of three telescopic arms, which are extended and retracted via two telescopic cylinders. Furthermore, the first arm 32 may be mounted to the column 31 using a hinge, allowing the first arm 32 to swing ±90° around the hinge. Additionally, the first arm 32 and the second arm 35 may also be mounted using a hinge.

[0042] Based on the above embodiments, preferably, the system further includes a base 5, a guide rail 6, a support base plate 7 for supporting the first positioning device 4 and the second positioning device 2, and a drive cylinder 8 for driving the support base plate 7 to move along the guide rail 6. Therefore, by controlling the operation of the drive cylinder 8, the support base plate 7 can move back and forth along the guide rail 6 to achieve the back and forth movement adjustment of the first positioning device 4 and the second positioning device 2.

[0043] Preferably, two leveling cylinders 10 and a ball joint 9 are provided between the supporting base plate 7 and the first positioning device 4, and between the supporting base plate 7 and the second positioning device 2, with the ball joint 9 located between the two leveling cylinders 10.

[0044] It should be noted that the two leveling cylinders 10 and one ball joint 9 can form a leveling device. The leveling device is used to adjust the position of the first positioning device 4 and the second positioning device 2. Furthermore, the leveling base 5 of the first positioning device 4 and the second positioning device 2 is the same. The leveling cylinders 10 can be servo cylinders to ensure high precision in the leveling operation.

[0045] Preferably, the first positioning device 4 includes a horizontally distributed first mounting base 41, a first guide rail 42 mounted on the first mounting base 41, a first laser 43, a first rack 44 located on one side of the first guide rail 42, a first reducer 45, and a first servo motor 46. The first laser 43 and the first reducer 45 are slidably mounted on the first guide rail 42 via a first slider. One end of the first reducer 45 meshes with the first rack 44, and the other end is connected to the drive shaft of the first servo motor 46. For example, two first lasers 43 can be mounted on the first mounting base 41, with the structure as follows: Figure 7 As shown.

[0046] Therefore, the first laser device 43 drives the first reducer 45 to move back and forth along the first rack 44 and the first guide rail 42 via the first servo motor 46. The first laser device 43 emits laser to the top to realize the positioning operation of drilling at the top. The first servo motor 46 can realize the fine adjustment of the position of the first laser device 43, and the relative position can be manually set via the touch screen.

[0047] Preferably, the second positioning device 2 includes a vertically distributed second mounting base 21, a lifting cylinder 22, a second guide rail 23, a mounting base plate 29 on the second guide rail 23, a third guide rail 28 on the mounting base plate 29, a second rack 24 on one side of the third guide rail 28, a second laser device 25, a second reducer 26, and a second servo motor 27. The second laser device 25 and the second reducer 26 are slidably mounted on the third guide rail 28 via a second slider. One end of the second reducer 26 meshes with the second rack 24, and the other end is connected to the drive shaft of the second servo motor 27. For example, four second laser devices 25 can be mounted on the second mounting base 21, with the structure as follows: Figure 6 As shown. Furthermore, the relative positions can be manually set via the touchscreen. That is, the overall height of the four second laser units 25 can be adjusted by jogging the lifting cylinder 22.

[0048] Therefore, the lifting cylinder 22 can push the second laser instrument 25 to move up and down along the second guide rail 23. The second laser instrument 25 drives the second reducer 26 to move up and down along the second rack 24 and the third guide rail 28 through the second servo motor 27, adjusting the position of the second laser instrument 25. The second laser instrument 25 emits laser light towards the tunnel sidewall, thereby locating the drilling position of the sidewall.

[0049] Preferably, the first positioning device 4, the second positioning device 2, the auxiliary arm drilling device 3, and the working platform 1 are all mounted on the flatbed cart 11. That is, a laser positioning device can be added to a traditional drilling device, and this laser positioning device can be integrated into platforms such as the flatbed cart 11 to achieve automatic positioning of the drilling location, increase drilling speed, assist manual drilling, reduce the labor intensity of workers, and improve the construction environment. Furthermore, the overall structure of this device is reasonable, stable, and reliable, meeting the requirements for automatic positioning drilling in tunnels and suitable for most rail engineering machinery.

[0050] It should be noted that the first positioning device 4 and the second positioning device 2, the first guide rail 42 and the second guide rail 23 and the third guide rail 28, the first mounting base 41 and the second mounting base 21, the first laser 43 and the second laser 25, the first reducer 45 and the second reducer 26, the first servo motor 46 and the second servo motor 27 mentioned in this application are only distinguished by their different positions and do not have any order of precedence.
