Technical Field

[0001] This utility model relates to the field of escape tunnel technology, and more specifically, to an installation structure for a temporary trestle for an escape tunnel. Background Technology

[0002] An escape tunnel is an emergency passage used in tunnel construction or building construction sites. It is usually a hollow tube to protect personnel for passage.

[0003] However, if the road surface is uneven with many potholes, it will greatly affect people's access to the escape tunnel. If the existing trestle is temporarily installed, the bottom support cannot be built in time, causing the trestle to be suspended in the air, resulting in instability and affecting people's passage. Utility Model Content

[0004] The purpose of this utility model is to provide a temporary trestle installation structure for escape pipelines, which solves the problem that when a trestle needs to be temporarily installed, it is impossible to build a bottom support in time, causing part of the trestle to be suspended in the pit, resulting in a decrease in the stability of the trestle and easy damage to the suspended part.

[0019] The following is combined Figures 1 to 3 This utility model will be described in detail.

[0020] An escape tunnel temporary bridge installation structure includes an escape tunnel 1, with a bridge 2 connected to one end of the escape tunnel 1. The top of the bridge 2 is provided with a fitting groove 201, and the bottom of the fitting groove 201 is provided with a lifting opening 2011. A deflecting rod 202 is connected to the middle of the fitting groove 201. A through block 2021 is provided on one side of the deflecting rod 202 near the bottom. A connecting block 2022 is provided on the top of the deflecting rod 202. A support component is connected to one side of the deflecting rod 202. The support component passes through the through block 2021 and moves up and down along the lifting opening 2011. A pressure sensor 203 is provided at the bottom of the bridge 2. Warning light strips 204 are provided on both sides of the deflecting rod 202. The deflecting rod 202 consists of several rods connected to the top sides of the bridge 2, and one end of each deflecting rod 202 is connected to the fitting groove 201 via a hinge shaft.

[0021] Firstly, when constructing escape route 1, if there are pits or uneven terrain on the ground, a trestle bridge 2 will be built at one end of escape route 1 to facilitate the quick entry of personnel into escape route 1. At the same time, a pressure sensor 203 is installed at the bottom of trestle bridge 2. The pressure sensor 203 is a strain gauge pressure sensor, which converts changes in pressure into changes in resistance for measurement. This is used to detect the weight of the number of people supported on trestle bridge 2, preventing damage to the trestle bridge due to excessive load.

[0022] Meanwhile, several matching slots 201 are arranged on both sides of the top of the trestle 2, and deflection rods 202 are connected to the matching slots 201. The warning light strips 204 on both sides of the deflection rods 202 emit light to warn of the edge of the trestle 2.

[0023] Furthermore, the support assembly includes a rotating rod 2023 and a lifting rod 2024. The rotating rod 2023 is connected to one side of the deflection rod 202, and the lifting rod 2024 is connected to the side wall of the rotating rod 2023. The top of the rotating rod 2023 passes through the connecting block 2022 for connection, and a disc is provided on the top of the rotating rod 2023 passing through the connecting block 2022. The lifting rod 2024 is a round rod sleeved on the side wall of the rotating rod 2023. Long strip-shaped protrusions are provided on both sides of the rotating rod 2023. The inner wall of the lifting rod 2024 is provided with grooves that cooperate with the protrusions on both sides of the rotating rod 2023. The rotating rod 2023 passes through the through block 2021, and the side wall of the rotating rod 2023 is threadedly matched with the inner wall of the through opening in the middle of the through block 2021.

[0024] Meanwhile, if the ground at the bottom of the trestle 2 is uneven and has potholes, the deflection rod 202 at the current position can be controlled to deflect and stand upright along the hinge axis at one end. Then, the rotation rod 2023 can be controlled to rotate. When the rotation rod 2023 rotates, it will drive the lifting rod 2024 to rotate together. Because the lifting rod 2024 is threadedly matched with the through block 2021, the lifting rod 2024 will descend along the rotation rod 2023 when rotating, extending out from the lifting opening 2011, thereby supporting the potholes. This provides temporary support for the suspended part of the trestle, and the upright deflection rod 202 will also form protection on both sides of the suspended part of the trestle 2.

[0025] Meanwhile, the inner wall of the lifting rod 2024 cooperates with the protrusions on both sides of the rotating rod 2023 through the long groove, so that when the rotating rod 2023 rotates, it will drive the lifting rod 2024 to rotate together, without affecting the lifting of the lifting rod 2024.

[0026] The following is a detailed implementation process of this utility model. First, when constructing the escape route 1, if there are pits or uneven terrain on the ground, a trestle bridge 2 will be built at one end of the escape route 1 to facilitate quick entry of personnel into the escape route 1. Simultaneously, a pressure sensor 203 is installed at the bottom of the trestle bridge 2. This pressure sensor 203 is a strain gauge pressure sensor, which converts pressure changes into resistance changes for measurement. This allows for the detection of the weight of the number of people supporting the trestle bridge 2, preventing damage due to excessive weight. Furthermore, several fitted grooves 201 are arranged on both sides of the top of the trestle bridge 2, and deflection rods 202 are connected to these grooves. Warning light strips 204 on both sides of the deflection rods 202 emit light. This allows the edge of the trestle 2 to be highlighted as a warning. If the ground at the bottom of the trestle 2 is uneven and has potholes, the deflection rod 202 at the current position can be controlled to deflect and stand upright along the hinge axis at one end. Then, the rotation rod 2023 is controlled to rotate. When the rotation rod 2023 rotates, it will drive the lifting rod 2024 to rotate as well. Because the lifting rod 2024 is threadedly matched with the through block 2021, the lifting rod 2024 will descend along the rotation rod 2023 during rotation, extending out from the lifting opening 2011 to support the pothole. This provides temporary support for the suspended part of the trestle, making it quick and convenient to provide temporary bottom support when temporarily installing the trestle 2.
