Description

Technical Field

[0001] This utility model relates to the field of tunnel operations, specifically to an adjustable tunnel fabric hanging construction platform that relies on a tunnel trestle. Background Technology

[0002] Tunnel fabric installation is a key protective procedure in tunnel construction. Its core function is to build a reliable waterproof barrier between the initial support and the secondary lining. It can not only block groundwater from seeping into the tunnel through the pores and cracks of the shotcrete layer, but also form a combined prevention and drainage system with drainage blind pipes to divert seepage and prevent water pressure from damaging the structure. At the same time, it can protect the initial support from water erosion, prevent grout loss or impurities from entering during the pouring of the secondary lining, and provide a dry working surface for subsequent lining construction and interior decoration, directly ensuring the long-term durability and operational safety of the tunnel.

[0003] However, traditional manual methods of hanging waterproofing membranes in locations such as low sidewalls are prone to accidents such as falls and collisions due to the narrow space and curved edges of tunnels, and the lack of a stable operating position for manual operation. To address this, an adjustable tunnel waterproofing membrane hanging platform based on a tunnel trestle is proposed, aiming to improve operational safety, especially optimizing the hanging conditions for waterproofing membranes in low sidewall areas.

However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0023] Example:

[0024] like Figures 1-4 As shown, this utility model provides an adjustable tunnel fabric-hanging construction platform relying on a tunnel trestle, including an upper connecting seat 1, a lower connecting seat 2, a main support arm 3, and a main hydraulic rod 4. Two sets of upper connecting seats 1 are respectively installed at the same height position on the upper part of two sets of trestle support legs. One end of the main support arm 3 is connected to the upper connecting seat 1 through a pivot. Two sets of lower connecting seats 2 are respectively installed at the same height position on the lower part of two sets of trestle support legs. The fixed end of the main hydraulic rod 4 is installed on each part of the main support arm 3 through a pivot. The telescopic end of the main hydraulic rod 4 is connected to the bottom of the other end of the main support arm 3 through a pivot. Platform height adjustment components 5 are bolted to the ends of both sets of main support arms 3. A working platform 6 that can slide vertically along the platform height adjustment components 5 is provided between the exterior of the two sets of platform height adjustment components 5.

[0025] Platform height adjustment component 5 includes height adjustment guide rod 51 and auxiliary hydraulic rod 52;

[0026] The height adjustment guide rod 51 is fixed to the end of the main support arm 3 by bolts. The working platform 6 is set outside the two sets of height adjustment guide rods 51. The fixed end of the auxiliary hydraulic rod 52 is installed on one side of the top of the height adjustment guide rod 51 through a rotating shaft. The telescopic end of the auxiliary hydraulic rod 52 is connected to the surface of the working platform 6 through a rotating shaft. When working, the auxiliary hydraulic rod 52 extends and drives the working platform 6 to move downward. When the auxiliary hydraulic rod 52 retracts, it drives the working platform 6 to move upward, so that the working platform 6 can be adjusted to fit the position of the tunnel wall.

[0027] The platform height adjustment component 5 also includes a supporting sleeve 53, which is fitted over the height adjustment guide rod 51. The working platform 6 is fixed to the supporting sleeve 53 by bolts. The working platform 6 is supported by the supporting sleeve 53. The working platform 6 has two sets of through holes that cooperate with the height adjustment guide rod 51. The working platform 6 is installed between the two sets of height adjustment guide rods 51 through the through holes. The working platform 6 is fixedly connected to the supporting sleeve 53 through the through holes. Driven by the auxiliary hydraulic rod 52, the working platform 6 moves vertically along the outside of the height adjustment guide rod 51. The supporting sleeve 53 moves synchronously along the outside of the height adjustment guide rod 51 when the working platform 6 moves. The supporting sleeve 53 supports the working platform 6 from the bottom, thereby ensuring the stability of the working platform 6 relative to the setting position of the height adjustment guide rod 51.

[0028] A walking channel 7 is installed between the upper surfaces of one end of the two main support arms 3. Both sides of the walking channel 7 are equipped with protective railings 71. The walking channel 7 and the railings 71 together form a passage area. Both sides of the work platform 6 are equipped with work railings 61. The work railings 61 and the railings 71 together form a protected work space. The work railings 61 and the railings 71 are connected to the work platform 6 and the walking channel 7 respectively by plug-in connection. In the working state, the plug-in connection can achieve quick installation to ensure the safety of the operation. In the transfer state, the plug-in connection can achieve quick removal of the work railings 61 and the railings 71.

[0029] A folding plate 62 is installed on the side of the working platform 6 via a hinge. The movable angle of the folding plate 62 is 0-90°. When the working platform 6 is driven by the auxiliary hydraulic rod 52 to move vertically along the height adjustment guide rod 51 to adjust its height, the position of the folding plate 62 on the edge of the working platform 6 changes synchronously with the adjustment of the position of the working platform 6 relative to the edge of the tunnel. At this time, the folding plate 62 rotates relative to the working platform 6 to maintain contact with the inner wall of the tunnel, thereby achieving adaptive filling of gaps and ensuring operational safety.
