Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a tunnel insulation section construction trolley. Background Technology

[0002] Due to the complex terrain in western China, high-altitude and frigid mountain roads are common. Because of the unique environment of these plateau and high-altitude areas, varying degrees of frost damage have occurred in the constructed road tunnels.

[0003] To prevent frost damage from extreme cold, a common method is to install an insulation layer between the secondary lining and the waterproofing liner. For example, in the Kangxiwa Tunnel project of the G580 Hotan section highway construction project, a rigid polyurethane insulation layer was installed on the surface of the secondary lining, and then a polymer mortar plastering + fiber reinforced board fireproof layer was installed on the outside of the insulation layer, which also served as interior decoration of the tunnel.

[0004] For the construction of tunnel insulation sections, insulation sections need to be installed on the sides and top of the tunnel. However, the existing tunnel construction trolleys have a construction platform on the top of the trolley. The construction platform can only install insulation boards on the top of the tunnel, and it is inconvenient to install insulation boards on the sides of the tunnel. Utility Model Content

[0005] Therefore, it is necessary to provide a tunnel insulation section construction trolley to address the problem that traditional tunnel construction trolleys can only install insulation boards on the top surface of the tunnel, and it is inconvenient to install insulation boards on the sides of the tunnel.

One end of the first load-bearing platform is hinged to the trolley frame, and one end of the first telescopic rod is hinged to the trolley frame; the other end of the first telescopic rod is hinged to the first load-bearing platform.

[0009] The second working platform is located on the side of the trolley frame and is used for constructing tunnel side insulation panels. The second working platform includes a second bearing platform and a second telescopic rod. One end of the second bearing platform is hinged to the trolley frame, one end of the second telescopic rod is hinged to the trolley frame, and the other end of the second telescopic rod is hinged to the second bearing platform.

[0010] In one embodiment, a first guardrail is provided around the perimeter of the first carrying platform.

[0011] In one embodiment, the second bearing platform is provided with a second guardrail around its perimeter, and the side of the second guardrail opposite to the side of the tunnel is provided with a gap for construction.

[0012] In one embodiment, the trolley frame is provided with a first ladder connecting the ground and the second work platform, and a second ladder connecting the second work platform and the first work platform.

[0013] In one embodiment, each side of the trolley frame is provided with two sets of the second working platforms, and the two sets of the second working platforms are spaced apart in the vertical direction.

[0014] In one embodiment, two sets of the second working platforms distributed in the vertical direction are connected by a third ladder.

[0015] In one embodiment, the trolley frame is provided with a first limiting frame, and the other end of the first bearing platform is inserted into the first limiting frame.

[0016] In one embodiment, the trolley frame is provided with a second limiting frame, and the other end of the second bearing platform is inserted into the second limiting frame.

[0017] The aforementioned tunnel insulation section construction trolley features a first working platform on top of the trolley frame for installing insulation panels on the tunnel ceiling, and a second working platform on the side of the trolley frame for installing insulation panels on the tunnel sides. Therefore, the tunnel insulation section construction trolley can install insulation panels across the entire tunnel cross-section, ensuring convenient and efficient construction.

[0031] Please see Figure 1 One embodiment of the tunnel insulation section construction trolley includes a trolley frame 10, a first working platform 20 and a second working platform 30.

[0032] The trolley frame 10 supports other components of the trolley. The bottom of the trolley frame 10 is equipped with wheels 12 for movement, facilitating positioning adjustments within the tunnel. In one embodiment, the trolley frame 10 is assembled from vertical rods 14 and horizontal beams 16 to form a support structure. The trolley frame 10 is provided with diagonal braces 18, which connect the vertical rods 14 and horizontal beams 16 to enhance the strength of the trolley frame 10.

[0033] The first working platform 20 is located on top of the trolley frame 10 and is used for installing insulation panels on the tunnel roof. The second working platform 30 is located on the side of the trolley frame 10 and is used for installing insulation panels on the tunnel sides. The second working platforms 30 are symmetrically arranged on both sides of the trolley frame 10 to install insulation panels on both sides of the tunnel and to maintain the stability of the trolley.

[0034] The first working platform 20 on the top of the trolley frame 10 can be used to construct the insulation board on the top of the tunnel, and the second working platform 30 on the side of the trolley frame 10 can be used to construct the insulation board on the side of the tunnel. Therefore, the tunnel insulation section construction trolley can construct the insulation section of the entire cross section of the tunnel, ensuring the convenience and efficiency of the tunnel insulation section construction.

[0035] In one embodiment, when the tunnel surface is uneven or the tunnel has a longitudinal slope, the front and rear of the construction trolley are at different heights, causing the first working platform 20 and the second working platform 30 to be tilted. The insulation boards piled on the first working platform 20 and the second working platform 30 are prone to slipping off, and the construction workers are also prone to losing their balance, which can easily lead to safety risks.

[0036] Therefore, please refer to Figures 2 to 4 The first working platform 20 includes a first supporting platform 21 and a first telescopic rod 22. One end of the first supporting platform 21 is hinged to the trolley frame 10. One end of the first telescopic rod 22 is hinged to the trolley frame 10, and the other end of the first telescopic rod 22 is hinged to the first supporting platform 21. By extending and retracting the first telescopic rod 22, the first supporting platform 21 can be driven to rotate around the hinge point to keep the first supporting platform 21 in a horizontal state.

[0037] In one embodiment, the trolley frame 10 is provided with a first limiting frame 23, and the other end of the first supporting platform 21 is inserted into the first limiting frame 23. The first limiting frame 23 can limit and guide the rotation of the first supporting platform 21, ensuring the stability of the movement of the first supporting platform 21, preventing swaying during the movement of the first supporting platform 21, and ensuring the safety of items and personnel on the platform. Furthermore, the end of the first supporting platform 21 inserted into the first limiting frame 23 is provided with a first roller 24. The first roller 24 contacts the inner wall of the first limiting frame 23, which can ensure the smooth movement of the first supporting platform 21 within the first limiting frame 23.

[0038] Specifically in this embodiment, the two ends of the first bearing platform 21 are respectively supported on two crossbeams 16, and the first bearing platform 21 is hinged to one of the crossbeams 16. The first limiting frame 23 is provided on the other crossbeam 16. The first telescopic rod 22 is hinged to the vertical rod 14. Bailey panels are laid on the first bearing platform 21 to form a platform.

[0039] Please see Figures 5 to 7 The second working platform 30 includes a second supporting platform 31 and a second telescopic rod 32. One end of the second supporting platform 31 is hinged to the trolley frame 10, and one end of the second telescopic rod 32 is hinged to the trolley frame 10. The other end of the second telescopic rod 32 is hinged to the second supporting platform 31. By extending and retracting the second telescopic rod 32, the second supporting platform 31 can be driven to rotate around the hinge point to keep the second supporting platform 31 in a horizontal state.

[0040] In one embodiment, the trolley frame 10 is provided with a second limiting frame 33, and the other end of the second bearing platform 31 is inserted into the second limiting frame 33. The second limiting frame 33 can limit and guide the rotation of the second bearing platform 31, ensuring the stability of the movement of the second bearing platform 31, preventing swaying during the movement of the second bearing platform 31, and ensuring the safety of items and personnel on the platform. Furthermore, the end of the second bearing platform 31 inserted into the second limiting frame 33 is provided with a second roller 34. The second roller 34 contacts the inner wall of the second limiting frame 33, which can ensure the smooth movement of the second bearing platform 31 within the second limiting frame 33.

[0041] Specifically in this embodiment, the side of the trolley frame 10 extends outward to form two supporting crossbeams 16. The two ends of the second bearing platform 31 are supported on the two crossbeams 16. One end of the second bearing platform 31 is hinged to one of the crossbeams 16. The second limiting frame 33 is provided on the other crossbeam 16. The second vertical rod 14 is hinged to the vertical rod 14. Bailey panels are laid on the second bearing platform 31 to form a platform.

[0042] Therefore, even if the trolley is located on uneven ground, the first telescopic rod 22 and the second telescopic rod 32 of the trolley can be extended and retracted to make the first working platform 20 and the second working platform 30 level, ensuring the safety of the insulation boards and personnel stored on the trolley, and ensuring the safety and reliability of the construction process.

[0043] In one embodiment, both the first telescopic rod 22 and the second telescopic rod 32 are electrically operated actuators. It is understood that in other embodiments, the first telescopic rod 22 and the second telescopic rod 32 may also employ other structures capable of telescopic movement, such as hydraulic cylinders, pneumatic cylinders, and lead screws. The structures of the first telescopic rod 22 and the second telescopic rod 32 may be the same or different. In this embodiment, the structure of the first telescopic rod 22 and the second telescopic rod 32 facilitates circuit design and connection.

[0044] Please refer to it again. Figure 1 In one embodiment, a first guardrail 25 is provided around the periphery of the first bearing platform 21. The first guardrail 25 is used to protect the first working platform 20, which can ensure the safety of the workers on the first working platform 20 and also prevent the insulation board from falling off the first working platform 20.

[0045] In one embodiment, a second guardrail 35 is provided around the perimeter of the second support platform 31, and a gap for construction is provided on the side of the second guardrail 35 opposite to the tunnel side. The second guardrail 35 can protect the second working platform 30, ensuring the safety of workers on the second working platform 30. Simultaneously, workers on the second working platform 30 can install insulation panels on the tunnel sidewall through the gap, preventing the guardrail from interfering with the insulation panel installation.

[0046] In one embodiment, each side of the trolley frame 10 is provided with two sets of second working platforms 30, which are designed to be alternately high and low along the vertical direction. The second working platform 30 located on the ground can be used to install insulation boards on the tunnel side near the bottom, while the second working platform 30 located on the higher ground can be used to install insulation boards on the middle part of the tunnel side, thus avoiding the inability of workers to install the higher insulation boards on the tunnel side due to insufficient height.

[0047] In one embodiment, the trolley frame 10 is provided with a first ladder 41 connecting the ground and the second work platform 30, allowing workers to climb from the ground onto the second work platform 30 via the first ladder 41. The trolley frame 10 is also provided with a second ladder 42 connecting the second work platform 30 and the first work platform 20. Workers on the second work platform 30 can climb onto the first work platform 20 via the second ladder 42. The two sets of second work platforms 30 distributed vertically are connected by a third ladder 43, enabling communication between the upper and lower levels of the second work platforms 30.

[0048] The aforementioned tunnel insulation section construction trolley features a first working platform 20 on top of the trolley frame 10 for installing insulation panels on the tunnel ceiling, and a second working platform 30 on the side of the trolley frame 10 for installing insulation panels on the tunnel sides. Therefore, the tunnel insulation section construction trolley can install insulation panels across the entire tunnel cross-section, ensuring convenient and efficient construction. Furthermore, to address uneven ground conditions, the first telescopic rod 22 can adjust the first load-bearing platform 21 to maintain horizontality, and the second telescopic rod 32 can adjust the second load-bearing platform 31 to maintain horizontality, thereby ensuring the safety of the insulation panels stored on the trolley and the personnel, and guaranteeing a safe and reliable construction process.
