Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-9 , the embodiments of the present invention provide a technical solution: a new type of multi-purpose tunnel drilling machine, including a walking system 1. The top of the walking system 1 is fixedly connected with a control system 2. The top of the control system 2 is fixedly connected with a measurement system 3. The top of the control system 2 and on one side of the measurement system 3 is fixedly connected with a longitudinal lifting system 4. The top of the longitudinal lifting system 4 is fixedly connected with a rotation system 6. The front of the rotation system 6 is fixedly connected with a laser positioning system 5. Both sides of the top of the rotation system 6 are fixedly connected with a lateral telescopic system 7. The right side of the lateral telescopic system 7 and on the right side of the rotation system 6 is fixedly connected with a drilling system 8.

[0033] The walking system 1 includes a frame 101. On both sides of the bottom of the frame 101, track wheels 102 are fixedly connected. On the front of the frame 101, a brake 103 is fixedly connected. On both the front and rear sides of the frame 101, skid shoes 104 are fixedly connected. The walking system 1 is a powerless trolley, mainly composed of four parts: the frame 101, the track wheels 102, the brake 103, and the skid shoes 104. The length of the trolley is 1800 mm, the width is 1050 mm, and the height is 250 mm. The distance between the track wheels 102 is 1406 mm. The frame 101 is welded by 3*5 mm square tubes. The track wheels 102 are made of nylon wheels with a diameter of 120 mm. The brake 103 device uses the brake 103 device originally equipped with the track wheels 102. The braking and unlocking handles of the two groups of brake 103 devices are interconnected through a round tube with a diameter of 26 mm and a wall thickness of 2 mm, so as to achieve the convenience of the brake 103. The skid shoe 104 device is based on the diameter of the track wheel 102.

[0034] The control system 2 includes a control box 201. On one side of the top of the control box 201, a control button 202 is fixedly connected. On the top of the right side of the control box 201 and on one side of the control button 202, a handle 203 is fixedly connected. The main control contents of the control system include the telescoping of the vertical cylinder, the telescoping of the horizontal cylinder, the telescoping of the electric push rod 601, the control of the Hilti TE7-C impact drill 801, etc. The main components in the control box 201 include relays, travel switches, control buttons, solenoid valves, electric push rods, AC contactors, emergency stop buttons, etc. The telescoping of the vertical cylinder is mainly controlled by the up and down buttons to control the relay, and the relay controls the solenoid valve. When the solenoid valve is opened, the cylinder is inflated and the cylinder starts to rise. When the down button is pressed, the solenoid valve opens in the reverse direction and the air in the cylinder is released and the cylinder starts to descend.

[0035] The horizontal telescoping system 7 and the drill control system are interlocked. When the control mode is the automatic mode, when the "extend" button is pressed, the solenoid valve opens and the cylinder starts to extend. When the cylinder extends to the wall at the drilling position, the normally closed contact of the travel switch above the drill is disconnected and the normally open contact is closed. At this time, the drill starts, and the cylinder on the drill side stops extending and waits for the reverse support cylinder to be in place. After the support point of the reverse support cylinder supports against the wall and touches the travel switch, the reverse support cylinder stops extending, and the cylinder on the drill side continues to move forward. At this time, drilling starts. When drilling reaches the adjusted depth, another group of travel switches is touched, the cylinder starts to contract, and the drill stops.

[0036] The telescoping of the electric push rod 601 is mainly achieved by controlling the control knob 202, controlling the relay to control the positive and negative poles of the power supply, thereby realizing the telescoping of the electric push rod 601.

[0037] The measurement system 3 includes a laser rangefinder 301, and the bottom of the laser rangefinder 301 is fixedly connected to the top of the control box 201. The measurement system 3 mainly measures the punching height. The main equipment consists of two parts: a ShenDaWei laser rangefinder and a rangefinder base. The rangefinder can calculate the current punching measurement height with one key according to the current inclination angle measured by the angle sensor using the Pythagorean theorem.

[0038] The above system components are made of high-strength aluminum alloy profiles, which are light in weight, high in strength, and have a reasonable cross-section force design. Moreover, they can be disassembled into multiple pieces at any time. The heaviest equipment weighs no more than 20 kg, and the disassembly and assembly only take 10 minutes. Therefore, it is extremely convenient for transportation up and down the line, and only 2 people are needed to complete it.

[0039] The longitudinal lifting system 4 includes a first air pipe 401. The back of the first air pipe 401 is fixedly connected to a longitudinal lifting rod 402, and the bottom end of the longitudinal lifting rod 402 is fixedly connected to the top of the control system 2. The longitudinal lifting system 4 mainly solves the height adjustment during electric drill punching. The system mainly uses an aluminum alloy single-acting cylinder with an outer diameter of 120 mm, an inner diameter of 101 mm for the first section, an outer diameter of 100 mm, and an inner diameter of 87 mm for the second section, with a total stroke of 3068 mm to solve the punching height problem. When the control system 2 is pressed to rise and the button is pressed, the pneumatic solenoid valve is connected to the intake mode, and the longitudinal cylinder of the longitudinal lifting system 4 starts to rise after being inflated. When the control system 2 is pressed to lower the button, the pneumatic solenoid valve runs in the reverse direction and is connected to the deflation mode, and the longitudinal cylinder of the longitudinal lifting system 4 deflates and starts to lower.

[0040] The laser positioning system 5 includes a laser lamp placement position 501. The bottom of the laser lamp placement position 501 is fixedly connected to a bracket 502, the back of the bracket 502 is fixedly connected to a base 503, and the back of the base 503 is fixedly connected to the front of the rotation system 6. The laser positioning system 5 solves the punching positioning problem. The current punching position can be positioned through the laser, and another laser positions the punched holes that have been completed, thus combining the two processes of punching and positioning into one. The system uses two 12V cross-shaped laser emitters, a laser electric adjustment base, and a fixed base.

[0041] The rotation system 6 includes a T-shaped support 603. The back of the bottom end of the T-shaped support 603 is fixedly connected to the top end of the longitudinal lifting rod 402. A second air pipe 602 is fixedly connected to the front of the T-shaped support 603. A first travel switch 604 is fixedly connected to the top of the second air pipe 602 and above the T-shaped support 603. An electric push rod 601 is fixedly connected between the included angles on the left side of the T-shaped support 603. The rotation system 6 mainly solves the rotation of the horizontal drilling system during drilling in circular tunnels and horseshoe-shaped tunnels, and also takes into account the fine height adjustment during drilling. The system mainly uses an electric push rod with a voltage of 24V, a diameter of 20mm, and a stroke of 1000mm. The electric push rod is installed below the fixed bracket of the horizontal cylinder. By adjusting the length of the electric push rod 601, the included angle between the horizontal telescopic system 6 and the longitudinal lifting system 4 is changed to adjust the drilling height.

[0042] The horizontal telescopic system 7 includes two horizontal telescopic rods 703. The bottoms of the two horizontal telescopic rods 703 are both fixedly connected to the top of the T-shaped support 603 through fixed clamps 704. A reverse support 701 is fixedly connected to the left end of the horizontal telescopic rod 703 and on the left side of the T-shaped support 603 through a second travel switch 702. A first guide rail 705 is fixedly connected to the top of the horizontal telescopic rod 703 and on the right side of the T-shaped support 603. The horizontal telescopic system 7 mainly solves the propulsion during electric drill drilling and the reverse support 701. The system mainly uses two double-acting cylinders with an outer diameter of 86mm, an inner diameter of 70mm, and a total stroke of 2888mm. A 3*5mm guide rail with a length of 1350mm is installed on the top of one of the cylinders to prevent the rotation of the cylinder caused by the reaction force of the electric drill during drilling. When the elongation button of the control system 2 is pressed, the pneumatic solenoid valves on the left and right sides are respectively connected to the intake mode, and the two horizontal cylinders of the horizontal telescopic system 7 start to extend. When the side of the Hilti TE7-C impact drill 801 reaches the tunnel wall and touches the first stage of the third travel switch 803 above the drill 8, the Hilti TE7-C impact drill 801 starts to operate at this time. The cylinder on the side of the Hilti TE7-C impact drill 801 stops advancing forward, and the cylinder on the side of the reverse support 701 continues to operate. When the reverse support 701 supports and compacts and touches the second travel switch 702, the cylinder on the side of the Hilti TE7-C impact drill 801 continues to advance forward and starts drilling. When the drilling depth reaches the set depth and touches the second stage of the third travel switch 803, the Hilti TE7-C impact drill 801 stops, and the pneumatic solenoid valves on the left and right sides are respectively connected to the air release mode, and the cylinders start to contract, and the drilling ends.

[0043] A drilling system 8 is fixedly connected to the right end of the horizontal telescopic rod 703 and at the right end of the first guide rail 705. The drilling system 8 includes a Hilti TE7-C impact drill 801.

[0044] The left end of the Hilti TE7-C SDS-plus drill 801 is fixedly connected to the right ends of the transverse telescopic rod 703 and the first guide rail 705. A second guide rail 802 is provided at the top of the Hilti TE7-C SDS-plus drill 801, and a third travel switch 803 is fixedly connected to the top of the Hilti TE7-C SDS-plus drill 801 and on the left side of the second guide rail 802; the drilling system 8 mainly controls the start, stop, drilling depth, etc. of the electric drill. The system uses an SDS-plus drill of the brand Hilti TE7-C with a power of 700W. The electric drill is fixed to the top of the cylinder by a base. A metal slide rail with a 23*24mm top bevel is installed on the upper part of the electric drill. Two travel switches are installed at the upper end of the slide rail. The rear travel switch can be adjusted back and forth to adjust the drilling depth. When the electric drill is pushed forward, the metal slide rail first touches the wall. When the slide rail moves backward and touches the first travel switch, the electric drill starts, and the cylinder on the electric drill side temporarily stops advancing forward. When the reverse support 701 cylinder is in place and touches the travel switch, the cylinder on the electric drill side continues to advance forward, and the electric drill starts drilling. After the drilling is in place, the slide rail touches the other travel switch, and at this time the electric drill stops and the cylinder retracts.
