Description

Technical Field

[0001] This invention relates to the field of power tunnel construction technology, specifically a drilling device for the top of a tunnel used in power construction. Background Technology

[0002] A power tunnel, also known as a cable tunnel, is a corridor or tunnel-like structure used to accommodate a large number of cables laid on cable supports. In addition to providing better protection for the cables, cable tunnels also make it convenient for people to inspect and maintain the cables. During the construction of a power tunnel, it is necessary to drill into the underground soil or rock layers, and then drill holes in the tunnel to facilitate the installation of cables and other devices.

[0003] Traditional tunnel top drilling devices for power construction typically involve moving the device directly to the desired drilling location and drilling directly through it. This requires limiting the movement of the rollers, and to ensure stability during drilling, multiple rollers need to be limited, which affects drilling efficiency. To address these issues, we propose a tunnel top drilling device for power construction. Summary of the Invention

[0009] Preferably, a placement groove is provided at each of the four corners of the rubber frame, and an arc-shaped laser emitting body is provided in the placement groove. The four arc-shaped laser emitting bodies are fixedly connected to the four corners of the top of the protective frame.

[0010] Preferably, the storage body includes a feeding pipe, a feeding hopper, an arc-shaped plate, a placement shell, a mounting plate, a storage shell, insert plates, a fixing frame, and a tensioning sleeve. The feeding pipe is fixedly connected to the bottom of the fixing shell, and a feeding hopper is provided at the top of the feeding pipe. Two feeding hoppers are fixedly connected to the bottom of the fixing shell in a group. An arc-shaped plate is fixedly connected to the top of the side of the two feeding hoppers that are close to each other. The arc-shaped plate is located at the bottom of the upper hydraulic telescopic body. The feeding pipe passes through the second fixing plate and is located inside the placement shell. A storage shell is provided inside the bottom of the placement shell. A mounting plate is fixedly connected to one side of the storage shell.

The lower hydraulic telescopic body is fixedly connected to the top of the base, the top of the lower hydraulic telescopic body is fixedly connected to a second fixed plate, and the bottom of the fixed end of the lower hydraulic telescopic body is fixedly connected to a first fixed plate. The bottom of the base has evenly distributed storage slots, and the support column is installed in the storage slots. The top of the support column is fixedly connected to the second bolt, and the outside of the second bolt is spirally connected to an internally threaded tube. The bottom of the internally threaded tube is fixedly connected to the base, and the bottom of the support column is hemispherical.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. With the set fixed frame, roller body, first fixed plate, second fixed plate, third fixed plate, drilling equipment and positioning body, the fixed frame can be moved conveniently under the action of the roller body. At the same time, the drilling equipment and positioning body are assembled under the action of the first fixed plate, second fixed plate and third fixed plate. The positioning body can drive the fixed frame to move upward, so that the roller body leaves the surface, making the drilling more stable. 2. The upper hydraulic telescopic body, connecting body, protective body, storage body, water tank, connecting hose and atomizing nozzle are set up. The upper hydraulic telescopic body can drive the connecting body to rise. Then, the drilling body set in the connecting body can drill holes in the top of the tunnel. During the drilling process, the atomizing nozzle sprays water from the water tank into the connecting body and the protective body through the connecting hose, reducing the spread of dust and improving the working environment for workers. 3. Through the fixed shell, drilling body, base plate, positioning spring, sliding rod, sliding plate, anti-detachment plate, protective frame and rubber frame, the fixed shell can drive the protective frame to move upward during the upward movement. When the rubber frame set at the top of the protective frame contacts the tunnel top, the base plate moves upward, causing the positioning spring to be compressed. Under the action of the positioning spring, the rubber frame seals the space between the protective frame and the tunnel top, reducing dust leakage. 4. Through the protective frame, rubber frame, placement groove, arc-shaped laser emitting body, slide groove, mounting plate, connecting block, positioning block and first bolt, the arc-shaped laser emitting body in the placement groove of the rubber frame can form a beam intersection point at the top of the tunnel, thereby determining the drilling position of the drilling body and making the drilling more accurate. Before drilling, the first bolt is rotated, and the first bolt drives the positioning block away from the surface of the fixed frame. Then the positioning block is moved up and down. The positioning block drives the connecting plate to slide in the slide groove of the protective frame through the connecting block, thereby adjusting the distance between the positioning block and the fixed shell. Then the first bolt is rotated in the opposite direction, and the first bolt pushes the positioning block to fit tightly with the protective frame, thereby positioning the positioning block. During the drilling process, when the top of the fixed shell comes into contact with the positioning block, the fixed shell cannot continue to move upward outside the protective frame. Therefore, the drill bit of the drilling body cannot continue to drill. The drilling depth of the drilling body is controlled by controlling the distance between the positioning block and the fixed shell. 5. Through the feeding pipe, feeding hopper, arc plate, placement shell, mounting plate, storage shell, insert plate, fixing frame and tension sleeve, the slag can be fed into the storage shell through the feeding pipe under the action of the feeding hopper and arc plate, so as to collect the slag. After collection, the storage shell can be taken out from the placement shell through the handle of the mounting plate, so as to process the slag uniformly. When the storage shell is put back into the placement shell, the insert plate is inserted into the tension sleeve of the fixing frame. Under the action of the elasticity of the tension sleeve, the insert plate is positioned to prevent the mounting plate and storage shell from falling off. 6. Through the set base, storage groove, support column, internal threaded pipe, second bolt and lower hydraulic telescopic body, the base can be pushed to move under the action of the lower hydraulic telescopic body until the support column contacts the ground to lift the fixed frame and limit the fixed frame. When the ground is uneven, the second bolt can be rotated. Under the action of the internal threaded pipe, the second bolt can drive the support column to move downward, so that the hemispherical end of the support column contacts the depression in the ground to achieve support, making the fixed frame more stable when drilling.

[0016] 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.

[0017] Please see Figures 1 to 8 In this embodiment of the invention, a tunnel top drilling device for power construction includes a fixed frame 1, a drilling device 6 for drilling and waste collection, and a positioning body 7 for positioning the fixed frame 1. Roller bodies 2, evenly distributed, are fixedly connected to the bottom of the fixed frame 1. A first fixed plate 3 is fixedly connected to the bottom of the fixed frame 1, a second fixed plate 4 is fixedly connected to the center of the fixed frame 1, and a third fixed plate 5 is fixedly connected to the top of the fixed frame 1. The drilling device 6 is installed on the fixed frame 1, the first fixed plate 3, and the second fixed plate 4. The positioning body 7 is fixedly connected to the bottom of the first fixed plate 3. This arrangement allows the fixed frame 1 to move easily under the action of the roller bodies 2. Simultaneously, the drilling device 6 and the positioning body 7 are assembled under the action of the first fixed plate 3, the second fixed plate 4, and the third fixed plate 5. The positioning body 7 can drive the fixed frame 1 upwards, causing the roller bodies 2 to leave the surface, making the drilling more stable.

[0018] As a further embodiment of the above invention: the drilling equipment 6 includes an upper hydraulic telescopic body 61, a connecting body 62, a protective body 63, a storage body 64, a water tank 65, a connecting hose 66, and an atomizing nozzle 67. The bottom of the upper hydraulic telescopic body 61 is fixedly connected to the third fixing plate 5. The connecting body 62 is installed on the top of the upper hydraulic telescopic body 61. The protective body 63 is installed inside and above the connecting body 62. The atomizing nozzle 67 is provided inside the protective body 63. The end of the atomizing nozzle 67 away from the protective body 63 is fixedly connected to the connecting hose 66. The other end of the 6 is fixedly connected to a water tank 65. Two water tanks 65 are fixedly connected to the top of the first fixed plate 3. The two water tanks 65 are set on the left and right sides above the positioning body 7. With this setting, the connecting body 62 can be raised by the upper hydraulic telescopic body 61. Then, the drilling body 622 set in the connecting body 62 is used to drill holes in the top of the tunnel. During the drilling process, the atomizing nozzle 67 sprays water from the water tank 65 into the connecting body 62 and the protective body 63 through the connecting hose 66, reducing the spread of dust and improving the working environment for workers.

[0019] As a further embodiment of the above invention: the connecting body 62 includes a fixed shell 621, a drilling body 622, a base plate 623, a positioning spring 624, a slide rod 625, a sliding plate 626, and an anti-detachment plate 627. The outer side of the fixed shell 621 is slidably connected to the fixing frame 1. The drilling body 622 is fixedly connected inside the fixed shell 621. A storage body 64 is installed at the bottom of the fixed shell 621. The base plate 623 is fixedly connected to both the front and rear sides of the lower part of the fixed shell 621. The slide rod 625 is fixedly connected to the top of the base plate 623. A positioning spring 624 is provided on the outer side of the slide rod 625. The anti-detachment plate 627 is fixedly connected to the end of the slide rod 625 away from the sliding plate 626. The slide rod 625 is close to the anti-detachment plate 627. A sliding plate 626 is provided on the outer side of one end. The protective body 63 includes a protective frame 631 and a rubber frame 632. The bottom of the protective frame 631 is fixedly connected to the evenly distributed sliding plates 626. The protective frame 631 is set inside the fixed shell 621. The top of the protective frame 631 is fixedly connected to the rubber frame 632. With this setting, the protective frame 631 can be driven to move upward as the fixed shell 621 moves upward. When the rubber frame 632 on the top of the protective frame 631 contacts the tunnel top, the bottom plate 623 moves upward, causing the positioning spring 624 to be compressed. Under the action of the positioning spring 624, the rubber frame 632 seals the protective frame 631 and the tunnel top, reducing dust leakage.

[0020] As a further embodiment of the above invention: Atomizing nozzles 67 evenly distributed are fixedly connected inside the protective frame 631. Slide grooves 635 are provided on both the left and right sides of the protective frame 631. A connecting plate 636 is provided within the slide grooves 635 of the protective frame 631. A connecting block 637 is fixedly connected to one side of the connecting plate 636. A positioning block 638 is provided on the outside of the connecting block 637. A first bolt 639 is threaded through the positioning block 638. The other end of the first bolt 639 is spirally connected to the connecting block 637. Placement slots 633 are provided at the four corners of the rubber frame 632. Arc-shaped laser emitting bodies 634 are provided within the placement slots 633. The four arc-shaped laser emitting bodies 634 are fixedly connected to the four corners of the top of the protective frame 631. Through this arrangement, under the action of the arc-shaped laser emitting bodies 634 within the placement slots 633 of the rubber frame 632, a beam convergence point can be formed at the top of the tunnel, thereby determining the drilling body 622. The drilling position of the drilling body 622 makes drilling more precise. Before drilling, the first bolt 639 is rotated, which drives the positioning block 638 away from the surface of the fixed frame 648. Then, the positioning block 638 is moved up and down. The positioning block 638 drives the connecting plate 636 to slide in the groove 635 opened in the protective frame 631 through the connecting block 637, thereby adjusting the distance between the positioning block 638 and the fixed shell 621. Then, the first bolt 639 is rotated in the opposite direction, which pushes the positioning block 638 to fit tightly with the protective frame 631, thereby positioning the positioning block 638. During the drilling process, when the top of the fixed shell 621 comes into contact with the positioning block 638, the fixed shell 621 can no longer move upward outside the protective frame 631. Therefore, the drill bit set in the drilling body 622 can no longer drill. The drilling depth of the drilling body 622 is controlled by controlling the distance between the positioning block 638 and the fixed shell 621.

[0021] As a further embodiment of the above invention: the storage body 64 includes a feeding pipe 641, a feeding hopper 642, an arc-shaped plate 643, a placement shell 644, a mounting plate 645, a storage shell 646, insert plates 647, a fixing frame 648, and a tensioning sleeve 649. The feeding pipe 641 is fixedly connected to the bottom of the fixing shell 621. A feeding hopper 642 is provided at the top of the feeding pipe 641. Two feeding hoppers 642 are fixedly connected to the bottom of the fixing shell 621 in a group. An arc-shaped plate 643 is fixedly connected to the top of the side of the two feeding hoppers 642 that are close to each other. The arc-shaped plate 643 is provided at the bottom of the upper hydraulic telescopic body 61. The feeding pipe 641 passes through the second fixing plate 4 and is provided inside the placement shell 644. A storage shell 646 is provided inside the bottom of the placement shell 644. A mounting plate 645 is fixedly connected to one side of the storage shell 646. Two insert plates 647 distributed front to back are fixedly connected to the top of the side of the mounting plate 645 that is close to the storage shell 646. A tensioning sleeve 649 is tightly fitted to the outside of the 647. A fixing frame 648 is fixedly connected to the outside of the tensioning sleeve 649. The two fixing frames 648 are fixedly connected to the front and rear sides above the housing 644, respectively. An upper hydraulic telescopic body 61 is provided between the two discharge pipes 641. The two discharge pipes 641 are respectively set on the left and right sides of the top of the housing 646. With this setting, the crushed material can be fed through the discharge pipes 641 under the action of the discharge hopper 642 and the arc plate 643. The debris is collected in the storage shell 646. After collection, the storage shell 646 is removed from the placement shell 644 through the handle on the mounting plate 645 for unified processing of the debris. When the storage shell 646 is put back into the placement shell 644, the insert plate 647 is inserted into the tension sleeve 649 on the fixing frame 648. Under the elastic action of the tension sleeve 649, the insert plate 647 is positioned to prevent the mounting plate 645 and the storage shell 646 from falling off.

[0022] As a further embodiment of the above invention: the positioning body 7 includes a base 71, a support column 73, an internally threaded tube 74, a second bolt 75, and a lower hydraulic telescopic body 76. The lower hydraulic telescopic body 76 is fixedly connected to the top of the base 71. The top of the lower hydraulic telescopic body 76 is fixedly connected to the second fixing plate 4. The bottom of the fixed end of the lower hydraulic telescopic body 76 is fixedly connected to the first fixing plate 3. The bottom of the base 71 has evenly distributed storage slots 72. The support column 73 is provided in the storage slots 72 of the base 71. The top of the support column 73 is fixedly connected to the second bolt 75. The outer side of the second bolt 75 is threaded... The device is connected to an internally threaded tube 74, the bottom of which is fixedly connected to the base 71. The bottom of the support column 73 is hemispherical. This design allows the base 71 to be moved by the lower hydraulic telescopic body 76 until the support column 73 contacts the ground, thus lifting the fixed frame 1 and limiting its position. When the ground is uneven, the second bolt 75 can be rotated. Under the action of the internally threaded tube 74, the second bolt 75 can drive the support column 73 to move downward, so that the hemispherical end of the support column 73 contacts the depression in the ground to provide support, making the fixed frame 1 more stable during drilling.

[0023] In practice: Powered by an external power source, the roller body 2 first moves the fixed frame 1 to a suitable position. Then, the external controller controls the arc-shaped laser emitting body 634 to emit light. At this time, the four arc-shaped laser emitting bodies 634 directly illuminate the tunnel ceiling, and the intersection of the four beams corresponds to the drilling body 622. The position of the fixed frame 1 is then adjusted so that the drill bit of the drilling equipment 6 is aligned with the desired drilling position. Then, the external controller controls the lower hydraulic telescopic body 76 to extend. At this time, the extended end of the lower hydraulic telescopic body 76 pushes the base plate 623 downward, so that the hemispherical position of the bottom of the support column 73 at the bottom of the base plate 623 contacts the ground. At this time, the fixed frame 1 can be lifted upward, so that the roller body 2 leaves the ground. To prevent the fixed frame 1 from moving, the drilling body 622 and the upper hydraulic telescopic body 61 are activated via an external controller. The upper hydraulic telescopic body 61 pushes the fixed shell 621 upwards inside the fixed frame 1, thereby moving the protective frame 631 upwards until the rubber frame 632 at the top of the protective frame 631 contacts the tunnel ceiling. The upper hydraulic telescopic body 61 continues to rise, and the nozzle is activated via the external controller. The nozzle then atomizes water from the water tank 65 and sprays it into the protective frame 631 through the connecting hose 66. As the fixed shell 621 moves upwards, the base plate 623 of the fixed shell 621 moves the sliding rod 625 and the support plate upwards. Simultaneously, the positioning spring 624 is compressed, causing the fixed shell 621 to move the discharge pipe 641 upwards. The feed pipe 641 moves upward within the placement shell 644, and the drilling body 622 moves upward under the action of the fixed shell 621 until the drill bit of the drilling body 622 gradually contacts the top of the tunnel. The drill bit of the drilling body 622 drills a hole in the top of the tunnel. During drilling, a large amount of dust and debris falls. Water mist is used to suppress the dust. The debris then falls downward, moving downward through the arc plate 643 and the feed hopper 642 into the receiving shell 646 within the placement shell 644, until the top of the fixed shell 621 contacts the positioning block 638. At this point, drilling is complete. Then, the upper hydraulic telescopic body 61 is reset by the external controller. At this time, the positioning spring 624 pushes the sliding plate 626 to move, and the sliding plate 626 pushes the protective frame 63. 1. Reset the drill bit of the drilling body 622 to stop rotating, and stop the water mist spraying of the atomizing nozzle 67 to achieve drilling of the tunnel device. This also reduces the spread of dust and the collection of debris. Then, control the retraction of the hydraulic telescopic body 76 to move the base plate 623 upward, so that the bottom of the roller body 2 contacts the ground. Then, push the fixed frame 1 to another position where drilling is needed. Then, control the extension of the hydraulic telescopic body 76 in the above manner to lift the fixed frame 1. If the ground is uneven, the second bolt 75 can be rotated directly. The second bolt 75 pushes the support column 73 downward under the action of the internal thread block, so that the hemispherical end of the support column 73 fits against the depression in the ground, thereby achieving stable support for the fixed frame 1.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
