Description

Technical Field

[0001] The invention relates to the field of tunnel excavation, in particular to a tunnel waterproofing board installation device. Background Art

[0002] After the initial support of the tunnel construction is completed, a layer of waterproof material needs to be laid before the secondary lining is constructed. As an important part of tunnel construction, the quality and progress of waterproof material laying directly affect the quality of tunnel construction. The traditional construction method of waterproof material laying is manual laying. During manual laying, the waterproof material roll needs to be rotated to unfold the waterproof board, and the waterproof material roll needs to be moved at the same time. However, due to the heavy weight of the waterproof material roll, it is very inconvenient to operate, requires a lot of manpower, and takes a long time to lay. In addition, the waterproof material has poor adhesion to the initial support surface, which is easy to produce bulges and cause voids in the secondary lining concrete, and the laying quality cannot be guaranteed.

[0003] Patent CN105736021A provides an automatic waterproof board trolley for tunnels, which mainly includes a trolley body, a traveling trolley, a cloth rolling device, a rolling device, and a trolley traveling track. The automatic waterproof board trolley for tunnels realizes the automatic application of waterproof boards through the cloth rolling device, and the applied waterproof cloth is rolled and pressed against the tunnel wall by the rolling device to avoid wrinkles on the waterproof boards, and the rolling device can move along the trolley traveling track with the traveling trolley and is applicable to the entire tunnel contour, but because the trolley travels in the form of a gear rack, the rack is installed on the upper surface of the rail head of the trolley traveling track, and because the tunnel cross-section is mostly a smooth curve connected by different curvatures, and the traveling track is also a smooth curve connected by different curvatures, the rack needs to be processed into different curvatures and the entire cross-section needs to be arranged, the rack processing precision requirements are high, the processing difficulty is large, the length is long, the production cost is high, and its volume is fixed, it cannot be folded, and it is not easy to carry. Patents CN204267053U and CN107559025A respectively provide a waterproof board trolley that uses a winch structure and a sprocket chain to make the trolley walk on the trolley track. The pulleys or sprockets are arranged at multiple locations along the walking track and the door frame. The number of pulleys or sprockets is large, the transmission setting and installation are complicated, the manufacturing cost is high, and the installation and maintenance are inconvenient. CN11005451B proposes that the present invention relates to a foldable arch frame type tunnel waterproof board installation vehicle, including a lower body, a support frame arranged on the lower body and extending / folding with the lower body, a display board arm, a display board pressing device arranged on the display board arm, a walking track that can be extended / folded, a walking trolley and a rotating arm; the display board arm and the display board pressing device are both extended / folded with the walking trolley, and the rotating arm located on the support frame drives the display board arm and the display board pressing device to move along the walking track through the walking trolley to achieve the installation of the tunnel waterproof board.

[0004] Therefore, it is of great significance to design a tunnel waterproofing board installation device with simple structure, easy transportation, convenient installation and operation, automatic laying of waterproof boards, good laying quality and high efficiency. Summary of the invention

[0041] Furthermore, the operating platform 9 is a telescopic platform, and the working range of the operator can be adjusted by stretching the platform.

[0042] Working principle.

[0043] Drive the work trolley 2 to the center of the ground in the pre-construction section of the tunnel waterproof layer and fix the work trolley 2, start the hydraulic system 23, and the hydraulic system 23 drives the support frame 3 to rotate along the rotation axis D27 by pushing the rotation axis E28. At the same time, the rotating control frame 4 rotates synchronously with the support frame 3 and the arm A6. When the support frame 3, the rotating control frame 4, and the arm A6 rotate to be vertical to the ground, turn off the hydraulic system 23, adjust the length of the arm A7 according to the radius of the tunnel, and ensure that the operating platform meets the requirements;

[0044] Start the motor B25, one end of the gear shaft 22 is installed in the gear bearing guide groove 221, and the other end is installed in the arm A6. The motor B25 rotates to drive the gear shaft 22 to rotate. Through the cooperation between the gear shaft 22 and the tooth groove 222, the gear shaft 22 is driven to rotate along the rotation control frame groove 5, and at the same time drives the arm A6 to rotate along the rotation axis C21.

[0045] Arm A6 rotates simultaneously with arm A7 and the clamping adjustment plate 8. When the clamping adjustment plate 8 rotates to the bottom of the tunnel, the motor B25 is stopped. The waterproof board 14 is installed on the waterproof board rotating barrel 19. One end of the waterproof board 14 is stretched to pass around the guide wheel 15, the clamping adjustment wheel B12 and the clamping adjustment wheel A13. The arm B7 is adjusted to clamp the waterproof board through the clamping adjustment plate 8 and the waterproof board rotating barrel fixing column 16 to clamp the waterproof board with the clamping adjustment wheel B12 and the clamping adjustment wheel A13. The waterproof board 14 is clamped to the initial support surface 1 of the tunnel and the waterproof board is initially fixed.

[0046] According to the construction progress of the waterproof board, the operator starts the motor B25 through the control system 26. The rotation of the motor B25 drives the gear shaft 22 to rotate. The gear shaft 22 cooperates with the tooth groove 221 to drive the gear shaft 22 to rotate along the groove 5 of the rotating control frame, and at the same time drives the arm A6 and the clamping adjustment plate 8 to rotate along the shaft C21. Because the initial support surface 1 of the tunnel is uneven, the distance between the clamping adjustment plate 8 and the initial support surface 1 of the tunnel is adjusted by pushing the clamping adjustment wheel power spring support pad 29 through the clamping adjustment wheel power spring 11 to ensure that the clamping adjustment wheel B12 and the clamping adjustment wheel A13 are in a clamped state with the initial support surface 1 of the tunnel.

[0047] According to the change of the operating angle of the boom A7, the angle of the operating platform 9 is adjusted at any time by starting the motor A24 to ensure that the operating platform 9 is always in a horizontal state, thereby ensuring the safety of the operators.

[0048] When the waterproof board is constructed to the other end of the tunnel, the motor B25 is stopped, the arm A7 is shortened after the waterproof board is cut off, the motor B25 is started to rotate in the opposite direction to restore the compression adjustment plate 8 to the initial working position, and the working trolley 2 is moved to construct the adjacent waterproof boards and connect the waterproof boards.

[0049] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the invention.
