Description

Technical Field

[0001] The utility model relates to the technical field of tunnel escape pipes, in particular to an escape pipe with a stable supporting structure. Background Art

[0002] In order to ensure the safety during tunnel construction, the laying of escape pipes is part of the preventive measures, which are usually started during the tunnel excavation process. In this way, once a disaster or other emergency occurs, the construction workers can quickly use the escape pipes for self-rescue and maximize their life safety. The existing escape pipes are generally composed of a pipe body and a rectangular frame. The rectangular frame fixes the pipe body. When the rectangular frame fixes the pipe body, the upper end of the pipe body is generally exposed. When the tunnel collapses, the rectangular frame generally cannot provide stable support for the collapsed objects, and the collapsed objects can easily crush the pipe body, affecting the safety of the escape pipe when in use. At the same time, the rectangular frame generally does not have adjustable support feet, and the tunnel ground is uneven. It is not convenient to adjust the height of the frame during the installation process, which is not conducive to the horizontal connection of the escape pipe. At the same time, the support feet are prone to be suspended after installation, and the support effect is poor. Utility Model Content

The supporting structure itself has multiple triangular structures, which can provide protection for the upper end of the pipe body and have good supporting stability. At the same time, it has quickly adjustable supporting feet, which is convenient for connecting multiple sections of escape ducts. At the same time, the supporting frame can provide good support, which greatly improves the safety of the escape duct when in use and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an escape pipe with a stable support structure, comprising an escape pipe and a support leg unit;

[0005] Escape pipe: Its outer sleeve is provided with evenly distributed triangular frames, the upper ends of the triangular frames are fixedly connected to the middle of the upper crossbeam, the front and rear ends of the upper crossbeam and the triangular frames are fixedly connected to the lower crossbeam, and two adjacent triangular frames are provided between each other with two diagonal braces, and the inclination directions of the two adjacent diagonal braces are opposite;

[0006] Support leg unit: It is symmetrically arranged at the lower end of the triangular frame. Its own supporting structure has multiple triangular structures, which provides good support stability. At the same time, it has quick-adjustable supporting feet to facilitate the connection of multiple sections of escape pipes. At the same time, it can provide good support for the frame, greatly improving the safety of the escape pipe when in use.

[0007] Furthermore, the support leg unit includes a sliding sleeve, a sliding column and a supporting foot. The sliding sleeve is symmetrically arranged on the front and rear sides of the lower end of the triangular frame. The interior of the sliding sleeve is slidably connected with the sliding column. The lower end of the sliding column extends out of the lower surface of the triangular frame and is provided with a supporting foot at the end, which can provide adjustable support for the triangular frame.

[0008] Furthermore, the support leg unit also includes a pressure rod, which is rotatably connected to the front and rear ends of the triangular frame respectively. The long sliding holes in the middle of the pressure rod are slidably connected to the vertically corresponding sliding columns, and the upper ends of the pressure rods extend out of the triangular frame to facilitate the downward control of the sliding columns.

[0009] Furthermore, the support leg unit also includes plug-in posts, which are respectively arranged at the upper ends of the pressure rods to facilitate the insertion of the external rod body.

[0010] Furthermore, the support leg unit also includes a spring sheet, which is arranged at the front and rear ends of the triangular frame through a support plate, and the upper ends of the spring sheets are matched with the vertically corresponding pressure rods to facilitate the positioning of the pressure rods.

[0011] Furthermore, nuts are provided at both the front and rear ends of the triangular frame, the middle parts of the nuts are threadedly connected with screw rods, and the lower ends of the screw rods are matched with the vertically corresponding pressure rods to facilitate the positioning of the pressure rods.

[0014] 1. During use, the triangular frame, upper beam, lower beam and diagonal brace form a supporting structure. There are various triangular structures inside the external bracket, and the supporting structure itself has good stability. At the same time, the upper beam is located directly above the escape pipe, which can provide stable support for the collapsed objects in the tunnel and provide good protection for the escape pipe, greatly improving the safety of the escape pipe when in use.

[0015] 2. During installation, the construction workers use steel pipes to connect with the plug columns, and then push the pressure rod downward through the steel pipes and the plug columns. The pressure rod rotates around the shaft at its lower end and drives the sliding column to move downward. The round shaft at the upper end of the sliding column slides relative to the long sliding hole in the middle of the pressure rod. The sliding column moves down along the sliding sleeve to drive the supporting foot to move down, and then the supporting foot contacts the ground, and then the triangular frame is lifted up. The height of the triangular frame can be quickly adjusted to facilitate the connection between the escape pipes. Then use a wrench to rotate the hexagonal column, and the hexagonal column drives the screw rod to rotate.
