Description

Technical Field

[0001] This utility model relates to a fire emergency device for railway tunnel construction. Background Technology

[0002] To ensure the safety of construction workers and the structural safety of the tunnel during construction, a series of fire emergency devices need to be prepared. In the event of a partial collapse during tunnel construction, a large amount of dust particles will be introduced into the tunnel. These particles will affect the visibility of construction workers, and fallen rocks will block the tunnel, preventing workers from escaping. Therefore, escape pipes are set up as emergency passages for construction workers during tunnel construction. Existing escape pipes are interconnected in multiple sections and are usually fixed on both sides using chain connections, clip connections, and clamp connections. However, this method can easily lead to soil, gravel, and other debris entering the pipes during a collapse. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fire emergency device for railway tunnel construction, so as to improve the support strength of the pipeline connection and prevent soil, dust and gravel from entering the pipeline.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a railway tunnel fire emergency device, comprising a pair of pipes and arch support components. The ends of the pipes used for connection are provided with protruding posts, and the protruding posts between adjacent pipes abut against each other. The pair of arch support components abut against the outer diameter surface of the protruding posts and form an arched support, with their bottoms abutting against the ground. The protruding posts are provided with grooves, and the opposing protruding posts are fixedly connected by locking members, which are arranged radially along the protruding posts. The arch support components are provided with protrusions extending into the grooves and adapted to the grooves at the corresponding positions.

[0005] As a further improvement of this utility model, the end faces of the paired arch support components used for abutment are provided with a plurality of concave and convex surfaces, the concave and convex surfaces of the opposing arch support components are staggered and matched, and the convex surface extends to the bottom of the concave surface. A locking member is provided on one side of the arch support component for threaded connection between the convex and concave surfaces.

[0006] As a further improvement of this utility model, the top of the arch support component is provided with an arc-shaped guide surface.

[0007] As a further improvement of this utility model, the two ends of the arch support component are respectively provided with flanges along the axial direction of the pipe, and the flanges abut against the outer diameter surface of the pipe.

[0008] As a further improvement of this utility model, a rubber pad is provided between the arch support component and the pipe, and the rubber pad is sleeved on the pipe and is arranged in a semi-enclosed manner.

[0009] The beneficial effects of this utility model are: by supporting the connection of the pipe with the arch support component, the connection can be reliably protected and foreign objects can be prevented from entering the pipe. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0016] Reference Figure 1-4 As shown, a railway tunnel fire emergency device includes a pair of pipes 1 and arch support components 2. The ends of the pipes 1 used for connection are provided with protruding posts 11, and the protruding posts 11 between adjacent pipes 1 abut against each other. The paired arch support components 2 abut against the outer diameter surface of the protruding posts 11 and form an arched support, with their bottoms abutting against the ground. The arched support components 2 can effectively disperse the pressure from falling rocks and improve the load-bearing capacity at the pipe 1 connection. The protruding posts 11 are provided with grooves 111, and the opposing protruding posts 11 are fixedly connected by locking members, with the locking members extending along the protruding posts 11. The radial arrangement of the arch support component 2 is such that a protrusion 21 extending into and fitting the groove 111 is provided at the position corresponding to the groove 111. The groove 111 has a flat surface that abuts against the protrusion 21. The flat surface is provided so that the protrusion 21 and the groove 111 can fit smoothly together. During installation, the protrusions 11 of the two pipes 1 are abutted together. The two protrusions 11 are fixed by locking the side of the groove 111. The protrusion 21 on the arch support component 2 is installed into the groove 111 of the protrusion 11, forming a clamping state for the two protrusions 11, and at the same time limiting the position of the arch support component 2.

[0017] The paired arch support components 2 have several concave surfaces 23 and convex surfaces 22 on their abutting end faces. The concave surfaces 23 and convex surfaces 22 of the opposing arch support components 2 are staggered, and the convex surfaces 22 extend to the bottom of the concave surfaces 23. One side of each arch support component 2 is provided with a locking member that threads the convex surfaces 22 and concave surfaces 23. The engagement of the convex surfaces 22 and concave surfaces 23 makes the connection between the opposing arch support components 2 tighter and facilitates quick installation and positioning. The top of each arch support component 2 is provided with an arc-shaped guide surface 24, which is used to guide fallen rocks away from the pipe 1 and prevent fallen rocks from accumulating above the pipe 1. The two ends of each arch support component 2 are respectively along the axial direction of the pipe 1. A flange is provided, which abuts against the outer diameter surface of the pipe 1. The flange increases the contact surface with the pipe 1, further improving the overall stability. A rubber pad 3 is provided between the arch support component 2 and the pipe 1. The rubber pad 3 is sleeved on the pipe 1 and is semi-enclosed. Since the rubber pad 3 is in a semi-enclosed state, it acts on the contact surface between the arch support component 2 and the pipe 1. After the locking parts between the protrusions 11 are installed, the rubber pad 3 is covered on the outer diameter surface of the pipe 1. By pressing it, it fully fits the pipe 1 and the groove 111 on the protrusion 11, so that it fully contacts the pipe 1. The rubber pad 3 can further buffer the impact of falling rocks on the pipe 1.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
