Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and more specifically to a construction device for the intersection of a pilot tunnel at the tunnel entrance. Background Technology

[0002] Tunnels are engineering structures buried in the strata of the earth and are a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels. In the past few years, the construction of high-speed railways in my country has encountered the use of outdated construction equipment and methods in tunnel construction, and simple steel bar splicing and steel structure welding are used to support the formwork.

[0003] Existing tunnel support devices cannot meet the needs of tunnels of different sizes, thus making them unsuitable for various construction environments. Furthermore, when the entire device is moved to the designated position by the casters, the casters may cause the device to shift when supporting the tunnel entrance, resulting in inadequate support. Construction at the tunnel entrance may also generate a large amount of dust, which obstructs visibility, pollutes the air, reduces air quality, and severely impacts work efficiency. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a construction device for the tunnel entrance guide tunnel intersection. Existing tunnel support devices cannot meet the needs of tunnels of different sizes, and therefore cannot be applied to different construction environments. At the same time, when the whole device is moved to the designated position by the moving wheels, the device may shift due to the moving wheels when supporting the tunnel entrance, which cannot better support the device. A large amount of dust may be generated during construction at the tunnel entrance. The large amount of dust generated during construction will obstruct the view, pollute the air, reduce air quality, and seriously affect work efficiency.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, a construction device for a tunnel entrance guide tunnel intersection includes an adjustment mechanism. The adjustment mechanism comprises two units, each with a support column symmetrically fixedly connected to its upper surface. Each support column has an electric telescopic rod fixedly connected to its upper surface.

Each clamping plate has a spray dust removal mechanism inside it. A water inlet is fixedly connected to the bottom end of the clamping plate located to the right of the control mechanism. Telescopic pipes are fixedly connected between the clamping plates.

[0006] Furthermore, the adjustment mechanism includes adjustment boxes, with support boxes fixedly connected inside each of the two adjustment boxes.

[0012] Furthermore, a through-hole pressure relief hole is integrally formed on the left side of the front surface of each of the multiple arc-shaped piston plates.

[0013] Furthermore, each of the support legs has a pointed conical plate fixedly connected to its bottom end.

[0014] The beneficial effects of the construction equipment for the tunnel entrance guide tunnel intersection of the present invention are as follows:

[0015] The adjustable mechanism can control the retraction of multiple moving wheels when multiple electric telescopic rods are extended, and extend multiple support legs outward to support the equipment, preventing the equipment from easily shifting when it is supported and fixed inside the tunnel. When multiple electric telescopic rods are retracted, multiple support legs are retracted and multiple moving wheels are extended at the same time, which makes it easier for operators to move the whole equipment and improves the overall flexibility of the equipment.

[0016] The control mechanism allows for the simultaneous extension of multiple clamping plates, thereby increasing the size of the tunnel entrance and adjusting the extension distance of the clamping plates. This facilitates the application of the equipment at different construction sites. Additionally, the multiple clamping plates contact the inside of the tunnel to extend multiple spray dust removal mechanisms to the outside of the clamping plates, preventing damage to these mechanisms during transportation or movement.

[0017] The spray dust removal mechanism sprays water through multiple atomizing nozzles. Simultaneously, multiple water pumps pressurize and drive multiple rotating discs to rotate repeatedly. These rotating discs, in turn, cause multiple piston plates to slide back and forth. This suction from the piston plates causes the atomizing nozzles to slide back and forth within multiple arc-shaped sliding grooves, thus effectively cleaning the dust generated during construction and preventing dust from obstructing the workers' vision and reducing construction efficiency.

Detailed Implementation

[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0028] According to one aspect of the invention, such as Figure 1-7As shown, a construction device for a tunnel entrance guide tunnel intersection is provided, including an adjustment mechanism 1. There are two adjustment mechanisms 1. The upper surfaces of the two adjustment mechanisms 1 are symmetrically fixedly connected with support columns 2. The upper surfaces of the multiple support columns 2 are fixedly connected with electric telescopic rods 3. The top ends of the output shafts of the multiple electric telescopic rods 3 are all fixedly connected with a control mechanism 4. The outer wall of the control mechanism 4 is provided with multiple clamping plates 5. The interior of the multiple clamping plates 5 is provided with a spray dust removal mechanism 6. The bottom end of the clamping plate 5 located to the right of the control mechanism 4 is fixedly connected with a water inlet 7. The multiple clamping plates 5 are fixedly connected with telescopic pipes 21.

[0029] When using this invention, support equipment is often required during construction at the tunnel entrance. This equipment can be pushed along the adjusting mechanisms 1 on both sides to control the extension of the moving wheels 111. Simultaneously, as the control mechanism 4 is raised by multiple electric telescopic rods 3, the multiple moving wheels 111 inside the two adjusting mechanisms 1 are retracted to prevent the equipment from becoming unstable when supporting and fixing the tunnel entrance. After the control mechanism 4 is raised to a certain height by the multiple electric telescopic rods 3, the control mechanism 4 drives multiple clamping plates 5 to extend outwards. These clamping plates 5 can support tunnel entrances of different sizes, improving the flexibility of the equipment. When all the clamping plates 5 are in contact with the inner wall of the tunnel entrance, the spray dust removal mechanism 6 inside the clamping plates 5 is pushed out, effectively preventing construction dust from drifting outside the tunnel and causing serious air pollution.

[0030] In this embodiment, the adjustment mechanism 1 includes an adjustment box 101. A support box 102 is fixedly connected inside each of the two adjustment boxes 101. A movable box 103 is fixedly connected inside each of the two adjustment boxes 101 and located on the front and rear surfaces of the two support boxes 102. Air chambers 104 are integrally formed at the front and rear of each of the two movable boxes 103. Piston plates 105 are slidably connected inside each of the multiple air chambers 104. Circular piston plates 106 are slidably connected inside each of the multiple support columns 2. Lifting telescopic rods 107 are fixedly connected to the bottom ends of each of the multiple circular piston plates 106. The bottom ends of the multiple lifting telescopic rods 107 are respectively... Extending into the interior of multiple movable boxes 103, each is fixedly connected to a piston plate 108. Each piston plate 105 is fixedly connected to an inclined support block 109 on the side near the multiple lifting telescopic rods 107. Each inclined support block 109 extends above the multiple piston plates 108 on the side near the multiple lifting telescopic rods 107. Each piston plate 105 is fixedly connected to a return spring 110 between the side away from the multiple lifting telescopic rods 107 and multiple air chambers 104. Each air chamber 104 is connected to multiple support columns 2. Each piston plate 108 is fixedly connected to a moving wheel 111 on its lower surface.

[0031] When this invention is in use, if support and fixation of the tunnel entrance are required, the device can be easily moved to a designated position by multiple movable wheels 111. Simultaneously, multiple inclined support blocks 109 support and fix the movable wheels 111. When multiple electric telescopic rods 3 extend outwards simultaneously, they drive the circular piston plates 106 inside the multiple support columns 2 to slide upwards. The multiple circular piston plates 106, through multiple lifting telescopic rods 107, drive multiple piston plates 108 to slide upwards inside the multiple movable boxes 103. At the same time, due to the obstruction of the multiple inclined support blocks 109, the multiple circular piston plates 108... Plate 106 pulls multiple lifting telescopic rods 107 to slide upward a distance inside multiple support columns 2, while retracting piston plates 105 inside multiple air chambers 104. That is, multiple piston plates 105 drive multiple inclined support blocks 109 to retract into the multiple air chambers 104. Then, circular piston plate 106 continues to drive piston plate 108 to slide upward inside multiple movable boxes 103 through lifting telescopic rods 107. Thus, multiple piston plates 108 retract multiple movable wheels 111 into the multiple movable boxes 103, preventing the entire equipment from shifting and causing unstable support when the equipment is supported at the opening.

[0032] In this embodiment, steel cables 112 are fixedly connected to the top of multiple circular piston plates 106. The ends of the multiple steel cables 112 away from the multiple circular piston plates 106 are fixedly connected to the outer side wall of the output shaft of multiple electric telescopic rods 3. The lower surfaces of the two support boxes 102 are symmetrically integrally formed with through-hole storage openings 113. Piston plates 114 are slidably connected inside the multiple support boxes 102. Support legs 115 are symmetrically fixedly connected to the lower surfaces of the multiple piston plates 114. The bottom ends of the multiple support legs 115 pass through the multiple storage openings 113. Air pipes 116 are fixedly connected between the two support boxes 102 and the multiple movable boxes 103. The lower surfaces of the multiple movable boxes 103 are integrally formed with through-hole storage openings 117. Multiple movable wheels 111 extend through the multiple storage openings 117 to the outside of the two adjustment boxes 101.

[0033] In use, when the multiple electric telescopic rods 3 extend outward, they drive multiple circular piston plates 106 to rise via multiple steel cables 112. When the multiple circular piston plates 106 drive multiple moving wheels 111 to retract into the multiple moving boxes 103, the compression of the multiple piston plates 108 inflates the two support boxes 102 through multiple air supply pipes 116. This causes the two piston plates 114 to slide downward under pressure, driving multiple support legs 115 to descend and support the entire equipment, preventing displacement of the equipment after the multiple clamping plates 5 clamp and fix the inner wall of the tunnel. When it is necessary to disassemble and remove the equipment, the multiple electric telescopic rods 3 retract. When the two piston plates 114 are pressed by the multiple support legs 115 and slide upward inside the two support boxes 102, the two air supply pipes 116 drive the multiple piston plates 108 to slide downward. When the multiple piston plates 108 slide to the moving position, the multiple reset springs 110 will cause the multiple inclined support blocks 109 to support the multiple piston plates 108 again. The multiple piston plates 108 drive the multiple moving wheels 111 to extend from the multiple storage ports 117. As the multiple piston plates 108 slide downward, they will also drive the multiple circular piston plates 106 and multiple steel cables 112 to reset, thus facilitating the operator to move the entire equipment and ensuring the stability of the support.

[0034] In this embodiment, the control mechanism 4 includes a control semicircular box 401. A drive motor 402 is fixedly connected to the rear inner surface of the control semicircular box 401. A bidirectional threaded rod 403 is fixedly connected to the front end of the output shaft of the drive motor 402. A support semicircular plate 404 is fixedly connected to the lower inner surface of the control semicircular box 401. The front end of the bidirectional threaded rod 403 passes through the support semicircular plate 404 and is rotatably connected to the rear inner surface of the control semicircular box 401 via a rotating shaft. Adjusting blocks 405 are threadedly connected to the outer side wall of the bidirectional threaded rod 403, both in front of and behind the support semicircular plate 404. Multiple... Adjusting sleeve 406, and a plurality of adjusting sleeves 406 are slidably connected to the interior of each of the plurality of adjusting sleeves 406. The ends of the plurality of supporting rods 407 away from the supporting semicircular plate 404 are fixedly connected to the plurality of clamping plates 5. The front and rear surfaces of the outer side walls of the plurality of adjusting sleeves 406 are integrally formed with through sliding grooves 408. The front and rear surfaces of the outer side walls of the plurality of supporting rods 407 and located inside the plurality of adjusting sleeves 406 are fixedly connected to connecting rods 409. The sides of the plurality of connecting rods 409 away from the plurality of adjusting sleeves 406 pass through the plurality of sliding grooves 408 respectively and are fixedly connected to the outer side walls of the two adjusting blocks 405 respectively.

[0035] When this invention is used, after the control semi-circular box 401 is raised to a certain position by multiple electric telescopic rods 3, the bidirectional threaded rod 403 is rotated by the set drive motor 402. At the same time, the bidirectional threaded rod 403 rotates and drives the two adjusting blocks 405 to slide relative to each other. The two adjusting blocks 405 drive multiple connecting rods 409 to slide along the inside of multiple sliding grooves 408. That is, multiple connecting rods 409 drive multiple support rods 407 to extend outward from the inside of multiple adjusting sleeves 406. Thus, multiple support rods 407 drive multiple clamping plates 5 to extend outward until they are in close contact with the inner wall of the tunnel, and then the drive motor 402 stops. If it is necessary to cancel the support, the drive motor 402 is started in reverse to retract the multiple clamping plates 5 at the same time.

[0036] In this embodiment, each of the multiple clamping plates 5 has a pressure box 8 fixedly connected to its inner sidewall. Each of the multiple pressure boxes 8 has a piston plate 9 slidably connected inside it. Each of the multiple piston plates 9 has a lower surface fixedly connected to a return spring 10 between it and the multiple pressure boxes 8. Each of the multiple clamping plates 5 has an integrally formed groove 11 on its outer sidewall. Each of the multiple piston plates 9 has a pressing rod 12 fixedly connected to its upper surface. The top ends of each pressing rod 12 extend through the multiple grooves 11 to the outer side of the multiple clamping plates 5 and are fixedly connected to a pressing spring. Each of the plates 13 and multiple clamping plates 5 has a compression box 14 fixedly connected to its inner sidewall and in front of multiple pressure boxes 8. Each of the multiple compression boxes 14 has a piston plate 15 slidably connected inside. Each of the multiple piston plates 15 has a compression rod 16 fixedly connected to its front surface. The front ends of the multiple compression rods 16 are fixedly connected to multiple spray dust removal mechanisms 6. Each of the multiple compression boxes 14 has a gas delivery hose 17 fixedly connected to its rear surface and multiple pressure boxes 8. Each of the multiple clamping plates 5 has an integrally formed through arc groove 18 on its front surface.

[0037] When this invention is in use, when multiple clamping plates 5 extend outward and contact the inner wall of the tunnel, multiple extrusion plates 13 are compressed and will drive multiple piston plates 9 to slide downward through multiple extrusion rods 12. That is, multiple air supply hoses 17 pressurize the interior of multiple extrusion boxes 14. The piston plates 15 inside the multiple extrusion boxes 14 are pressured and drive the spray dust removal mechanism 6 to slide as a whole through the extrusion rods 16. The multiple spray dust removal mechanisms 6 are extended to the outside of multiple clamping plates 5 through multiple arc-shaped grooves 18. This prevents the spray dust removal mechanism 6 from being damaged by bumps during transportation or movement. At the same time, the multiple spray dust removal mechanisms 6 prevent construction dust from polluting the urban environment and causing serious air pollution. When the equipment is unsupported, the multiple return springs 10 will return the multiple extrusion plates 13 and multiple spray dust removal mechanisms 6 to their original positions.

[0038] In this embodiment, the spray dust removal mechanism 6 includes an arc-shaped piston plate 601. Multiple arc-shaped piston plates 601 are slidably connected to the interior of multiple clamping plates 5. A water pump 602 is fixedly connected to the rear surface of each of the multiple arc-shaped piston plates 601. Sliding plates 603 are slidably provided on the left and right sides of the interior of each of the multiple arc-shaped piston plates 601. An arc-shaped sliding groove 604 is integrally formed on the front surface of each of the multiple arc-shaped piston plates 601. An arc-shaped sealing plate 605 is provided on the front surface of the interior of each of the multiple arc-shaped piston plates 601 and behind the multiple arc-shaped sliding grooves 604. The left and right sides of the multiple arc-shaped sealing plates 605 are fixedly connected to the multiple sliding plates 603. Multiple atomizing nozzles 606 are fixedly connected to the front surface of each of the multiple arc-shaped sealing plates 605. The front ends of the multiple atomizing nozzles 606 pass through the multiple arc-shaped sliding grooves 604.

[0039] When this invention is used, when multiple clamping plates 5 are in close contact with the inner side of the tunnel and multiple arc-shaped piston plates 601 slide outward, multiple arc-shaped piston plates 601 drive multiple atomizing nozzles 606 to extend from multiple arc-shaped grooves 18. Then, water is delivered to the interior of multiple clamping plates 5 through the water inlet 7 and multiple telescopic pipes 21. At the same time, multiple water pumps 602 are activated to deliver water to the interior of multiple arc-shaped piston plates 601. Then, the water is sprayed out through the multiple atomizing nozzles 606 to effectively prevent dust from drifting out of the tunnel and also to prevent a large amount of dust from obstructing the vision of construction personnel, thereby affecting construction efficiency.

[0040] In this embodiment, a connecting pipe 607 is fixedly connected to the inner rear surface of multiple arc-shaped piston plates 601 and in front of multiple water pumps 602. A rotating rod 608 is rotatably connected to the inner left side of each of the multiple connecting pipes 607 via a rotating shaft. The right end of each of the multiple rotating rods 608 extends to the right side of the multiple connecting pipes 607 and is fixedly connected to a rotating disc 609. A toggle plate 610 is fixedly connected to the outer wall of each of the multiple rotating rods 608 and inside the multiple connecting pipes 607. A second pressure box 611 is fixedly connected to the inner lower surface of each of the multiple arc-shaped piston plates 601. A fifth piston plate 612 is slidably connected to the inside of each of the multiple second pressure boxes 611. A through vertical groove 613 is integrally formed on the rear surface of each of the multiple second pressure boxes 611. A connecting plate 614 is fixedly connected to the rear surface of multiple piston plates 612. The rear ends of the multiple connecting plates 614 extend through multiple vertical slots 613 to the rear of multiple pressure boxes 611. A connecting column 615 is fixedly connected to the right side of multiple rotating discs 609. A push rod 616 is rotatably connected to the outer wall of the multiple connecting column 615 via a rotating shaft. A connecting column 617 is fixedly connected to the right side of the multiple connecting plates 614 and to the outer side of the multiple pressure boxes 611. The front ends of the multiple push rods 616 are rotatably connected to the outer wall of the multiple connecting column 617 via a rotating shaft. A gas delivery hose 618 is fixedly connected between the multiple pressure boxes 611 and the sliding plate 603 located on the right side inside the multiple arc-shaped piston plates 601.

[0041] In use, when multiple water pumps 602 control the water source to enter multiple arc-shaped piston plates 601, multiple connecting pipes 607 transport the water to the interior of the arc-shaped piston plates 601. The water speed drives multiple actuating plates 610 to rotate, which in turn drives a rotating rod 608 to rotate. Simultaneously, the rotating rod 608 drives a rotating disk 609 to rotate. The repeated rotation of the rotating disk 609 drives the connecting posts 615 to rotate repeatedly. The connecting posts 615, through multiple push rods 616, drive multiple connecting plates 614 to move up and down reciprocally. Plate 614 drives multiple piston plates 612 to slide back and forth inside multiple pressure boxes 611, thereby drawing air through multiple air delivery hoses 618 to the right side of the interior of multiple arc-shaped piston plates 601. The sliding plate 603 on the right side of the interior of the multiple arc-shaped piston plates 601 is subjected to pressure and slides back and forth inside the multiple arc-shaped piston plates 601. That is, the multiple sliding plates 603 drive multiple arc-shaped sealing plates 605 to slide back and forth inside the multiple arc-shaped piston plates 601. The multiple arc-shaped sealing plates 605 drive multiple atomizing nozzles 606 to slide left and right along multiple arc-shaped sliding grooves 604, which can better deal with the dust generated during tunnel construction.

[0042] In this embodiment, a through-hole pressure relief hole 19 is integrally formed on the left side of the front surface of multiple arc-shaped piston plates 601. The multiple pressure relief holes 19 can effectively release the air pressure inside the left side of the multiple arc-shaped piston plates 601, which facilitates the reciprocating sliding of multiple atomizing nozzles 606 inside multiple arc-shaped sliding grooves 604.

[0043] In this embodiment, the bottom ends of multiple support legs 115 are all fixedly connected with pointed cone plates 20. The multiple pointed cone plates 20 can better support and fix the overall equipment, preventing the equipment from shifting during support.

[0044] The working principle of this device is as follows: When using this invention, support equipment is often required during construction at the tunnel entrance. The device can be pushed along the adjusting mechanisms 1 on both sides to control the extension of the moving wheels 111. Simultaneously, when the control mechanism 4 is raised as a whole by multiple electric telescopic rods 3, the multiple moving wheels 111 inside the two adjusting mechanisms 1 are retracted to prevent the device from being unstable when supporting and fixing the tunnel entrance. After the control mechanism 4 is raised to a certain height by multiple electric telescopic rods 3, the control mechanism 4 drives multiple clamping plates 5 to extend outwards. These clamping plates 5 can support tunnel entrances of different sizes, improving the flexibility of the device. When all the clamping plates 5 are in contact with the inner wall of the tunnel entrance, the spray dust removal mechanism 6 inside the clamping plates 5 is pushed out, effectively preventing construction dust from drifting outside the tunnel and causing serious air pollution.

[0045] All electrical components mentioned in this article are real-world electrical components.

Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
