Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a multi-head rock drilling rig for tunnel excavation and propulsion. Background Technology

[0002] During tunnel excavation and propulsion, drilling rigs are needed to drill through the inner walls of some tunnels. Traditional single-head drilling rigs are complex in structure and difficult to move. Furthermore, single-head drilling rigs have low drilling efficiency, which affects the quality of drilling. Additionally, the drilling position is difficult to adjust, failing to meet the drilling requirements at different positions, angles, and heights. Therefore, to address these issues, a multi-head rock drilling rig for tunnel excavation and propulsion is proposed. Utility Model Content

[0003] The present invention addresses the problem of providing a multi-head rock drilling rig for tunnel excavation and advancement, which is compact in size and easy to move. During use, the position, height, and angle of the drilling tools can be adjusted to move the drilling tools to the outside of the rock drilling position, thereby meeting the rock drilling needs in different environments. At the same time, by setting multiple drilling tools, multi-head rock drilling can be achieved, effectively improving the rock drilling quality and efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-head rock drilling rig for tunnel excavation includes a propulsion frame.

The rotation angle of the limit rods inside the limit grooves is -45° to +45°. As the structural guard plate rotates, the limit rods can have a rotation range of -° inside the limit grooves, thereby facilitating the adjustment of the angle of the structural guard plate.

[0010] Furthermore, both sides of one end of the second guide rail slide are welded with flip-up ear plates, and a follower rotary seat is provided between the two flip-up ear plates. A third rotary motor is fixedly installed at the center of the outer end face of one of the flip-up ear plates, and the motor shaft of the third rotary motor passes through the flip-up ear plate and is fixedly connected to the follower rotary seat.

[0011] Furthermore, the positioning component includes a first electric cylinder, two first electric cylinders are respectively fixedly installed at both ends of the end face of the mounting base, and the bottom end of the first electric cylinder passes through a communicating groove. A first piston rod is installed at the center of the top end of the first electric cylinder, and an adjusting base is connected to the top end of the two first piston rods.

A locking base is fixedly installed through the top end of the first rotating shaft, and the bottom end of the protective baffle is fixedly connected to the locking base. The positioning component facilitates the adjustment of the height and angle of the protective baffle, thereby meeting the drilling requirements in different directions.

[0012] Furthermore, the bottom end face of the propulsion frame is fixed with movable rollers by bolts, and the movable rollers are universal self-locking rollers; they are easy to move and have the effects of steering and stopping, which greatly improves the convenience of displacement.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] See Figures 1 to 7 A multi-head rock drilling rig for tunnel excavation includes a propulsion frame 1, which provides robust and stable support and load-bearing capacity, facilitating the installation and fixing of equipment parts. Dust baffles 3 are fixedly installed at both ends of the top edge of the propulsion frame 1, and a first electric guide rail 4 is fixedly installed at the center of the bottom inner side of the dust baffle 3. The dust baffles 3 effectively cover and block dust from the first electric guide rail 4, thereby reducing the impact of dust on the first electric guide rail 4. A first guide rail slide 5 is connected to the top of the first electric guide rail 4, and a mounting base 6 is provided between two first guide rail slides 5. When the first electric guide rail 4 and the first guide rail slide 5 are working, they can drive the mounting base 6 to adjust its position. The top of the push frame 1 has a connecting groove 2 at the center of both ends, and the mounting base 6 is located above the top of the connecting groove 2. The mounting base 6 has a positioning component 7 at the center of its end face, and a protective baffle 8 is provided at the top of the positioning component 7. The positioning component 7 facilitates the adjustment of the height and angle of the protective baffle 8 to meet the requirements of drilling at different positions.

One end of the drilling shaft 915 is fixedly connected to the tool holder 916. When the second electric cylinder 91 is working, the position of the structural guard plate 97 can be adjusted by the second piston push rod 93. When the second rotary motor 94 is working, the structural guard plate 97 is driven to adjust its angle by the second rotary shaft 95. At the same time, when the second electric guide rail 99 is working, the second guide rail slide 910 slides, thereby adjusting the position of the drilling tool 917 a second time. Meanwhile, the third rotary electric... When the machine 912 is working, the motor shaft drives the follower rotary seat 913 to rotate between the flip ear plates 911, thereby adjusting the drilling angle of the drilling tool 917. The position of the drilling tool 917 is adjusted three times until the drilling tool 917 is in a suitable drilling position. At the same time, the drilling motor 914 is working, which enables the drilling shaft 915 to drive the tool holder 916 and the drilling tool 917 to rotate at high speed. The second electric cylinder 91 and the second piston push rod 93 can push the drilling tool 917 to move. Multi-head drilling is achieved by using multiple rotating drilling tools 917.

[0027] Positioning plates are provided on the top sides of both ends of the mounting base 6, and one end of each positioning plate is inserted into the dust baffle 3 and fixedly connected to the top end face of the first guide rail slide 5.

[0028] The protective baffle 8 has mounting rods 92 welded around its center on all four sides. The inner ends of the four mounting rods 92 are fixedly connected to the outer walls of the second electric cylinder 91.

Limiting grooves 98 are opened on the top and bottom sides of the end face of the structural guard plate 97, and the two limiting rods 96 are respectively inserted into the inside of the limiting grooves 98. The rotation angle of the limiting rods 96 inside the limiting grooves 98 is -45° to +45°. As the structural guard plate 97 rotates, the limiting rods 96 can have a rotation range of 0-90° inside the limiting grooves 98, thereby facilitating the adjustment of the angle of the structural guard plate 97.

[0030] The positioning component 7 includes a first electric cylinder 71. Two first electric cylinders 71 are respectively fixedly installed at both ends of the end face of the mounting base 6, and the bottom end of the first electric cylinder 71 passes through the communicating groove 2.

The positioning component 7 facilitates the adjustment of the height and angle of the protective baffle 8 to meet the drilling requirements in different directions. When the first electric cylinder 71 is working, the first piston push rod 72 can push the adjusting base 73 to adjust its height. When the first rotary motor 74 at the bottom of the adjusting base 73 is working, the first rotary shaft 75 drives the locking base 76 to adjust its angle, thereby adjusting the orientation angle of the protective baffle 8 and moving the drilling tool 917 to the outside of the rock drilling position.

[0031] The bottom end face of the propulsion frame 1 is fixed with movable rollers 10 by bolts, and the movable rollers 10 are universal self-locking rollers; they are easy to move and have the effects of steering and stopping, which greatly improves the convenience of displacement.
