Specifically, when the tunnel escape pipeline 2 is a circular pipe, the length of the circumferential limiting piece 12 basically extends along the arc direction, in other words, the circumferential limiting piece 12 is an arc-shaped rod, and the extending arc line is a major arc; when the tunnel escape pipe 2 is a square pipe, the length of the circumferential limiting member 12 extends along a substantially polygonal line, and the circumferential limiting member 12 is substantially rectangular with an opening. The axial limiting piece 13 extends along the axial direction of the tunnel escape pipeline 2, and two ends of the axial limiting piece are respectively connected with the two circumferential limiting pieces 12. Specifically, the axial limiting member 13 may be substantially rod-shaped, and one end of the axial limiting member in the length extending direction is connected to one of the circumferential limiting members 12, and the other end of the axial limiting member is connected to the other circumferential limiting member 12.

Two ends of the axial limiting piece 13 are respectively connected with two circumferential limiting pieces 12, and the axial limiting piece further fixes and supports the circumferential limiting pieces 12. The utility model provides a tunnel pipeline 2 of fleing's supplementary fixing device 1 helps making tunnel pipeline 2 of fleing positional stability, and simple structure, and the cost is lower relatively.
In some embodiments, the auxiliary fixing device 1 further comprises a bent rib, and both ends of the bent rib are used for being connected with the outer wall of the tunnel escape pipeline 2 to form a positioning space. Specifically, a positioning space is formed between the bent rib and the outer wall of the tunnel escape pipeline 2. The circumferential stopper 12 passes through the positioning space. The same circumferential position-limiting member 12 can pass through two or more positioning spaces. For example, at least two bent ribs are connected to the same position in the axial direction of the tunnel escape pipe 2, and are distributed at intervals in the circumferential direction of the tunnel escape pipe 2, and one circumferential limiting member 12 sequentially passes through two positioning spaces formed by the two bent ribs and the outer wall of the tunnel escape pipe 2. Specifically, the length of the bent rib may extend along an arc direction or may extend along a broken line direction. Through setting up the curved muscle, can further play the limiting displacement to circumference locating part 12, avoid circumference locating part 12 to produce the relative displacement along 2 axis directions of tunnel escape pipe 2 for tunnel escape pipe 2.
In some embodiments, referring to fig. 3, 4 and 5, the auxiliary fixing device 1 further includes a flexible cushion layer 16, specifically, the tunnel escape duct 2 can be formed by axially splicing a plurality of pipe sections 21, and the flexible cushion layer 16 is configured to be disposed between two adjacent pipe sections 21 of the tunnel escape duct 2. The compliant pad 16 is in the form of a ring. One end in the axial direction is provided with a first annular groove 161, and the other end is provided with a second annular groove 162. In particular, the shape of the flexible cushion 16 is adapted to the shape of the tunnel escape duct 2. When the flexible cushion layer 16 is used for the round tunnel escape pipeline 2, the flexible cushion layer is a circular ring; when used in a rectangular tunnel escape duct 2, the flexible cushion 16 is a rectangular ring. The first annular groove 161 and the second annular groove 162 extend in the circumferential direction of the flexible cushion layer 16, which is the circumferential direction or the circumferential length direction of the annular shape of the flexible cushion layer 16. The first annular groove 161 and the second annular groove 162 are used to receive the end of the pipe section 21 of the tunnel escape pipe 2. Specifically, the end of one of the pipe sections 21 is inserted into the first annular groove 161, and the end of the other pipe section 21 is inserted into the second annular groove 162. The compliant pad 16 is made of a flexible material so that the compliant pad 16 has a certain deformation capability, for example, the compliant pad 16 may be made of a rubber material. By arranging the flexible cushion layer 16 to be matched with the two adjacent pipe joints 21, the sealing performance of the tunnel escape pipeline 2 can be improved.
In some embodiments, one end of the axial limiting member 13 is rotatably connected to one of the circumferential limiting members 12, and the rotation axis is a length extending direction of the axial limiting member 13, in other words, the axial limiting member 13 can rotate around its length extending direction relative to one of the circumferential limiting members 12. The other end of the axial limiting piece 13 is in threaded connection with another circumferential limiting piece 12, and when the axial limiting piece 13 rotates, the axial limiting piece 13 generates relative displacement along the axial direction of the tunnel escape pipe 2 relative to the circumferential limiting piece 12 in threaded connection with the axial limiting piece 13.
The connection of the axial stop element 13 to the circumferential stop element 12 can be realized in the following manner: referring to fig. 6 and 7, the axial limiting member 13 includes a rod 131, a head 132 and a nut 135. The length of the rod body 131 extends along the axial direction of the tunnel escape pipeline 2, one section of the rod body 131 is a polish rod, the other section of the rod body 131 is provided with external threads, the diameter of the polish rod section 133 of the rod body 131 is smaller than the small diameter of the external thread section 134, in other words, the diameter of the polish rod section 133 of the rod body 131 is smaller than the diameter of the circumference of the thread root of the external thread section 134. The end 132 is fixedly disposed at one end of the rod body 131 close to the polish rod, and the cross-sectional size of the end 132 is larger than that of the rod body 131. The nut 135 is adapted to a section of the rod 131 provided with an external thread.
A threaded hole 121 is formed in the circumferential limiting piece 12; the polish rod segment 133 of the rod body 131 passes through the threaded hole 121 of one of the circumferential position-limiting members 12, and since the diameter of the polish rod segment 133 is smaller than the small diameter of the threaded hole 134, it can be understood that the polish rod segment 133 can rotate in the threaded hole 121 of the circumferential position-limiting member 12 and does not contact the inner wall of the threaded hole 121 of the circumferential position-limiting member 12, and since the end head 132 can be connected with the bottom rib of the circumferential position-limiting member 12, the polish rod segment 133 can only rotate relative to the circumferential position-limiting member 12 at that end, and does not move relative to the circumferential position. The threaded section 134 is in threaded fit with the threaded hole 121 of the other circumferential limiting member 12, and when the rod body 131 rotates, the threaded section 134 interacts with the threaded hole 121 of the circumferential limiting member 12, so as to move relative to the circumferential limiting member 12 in the axial direction of the tunnel escape pipe 2. For example, the distance between the two circumferential stoppers 12 can be shortened, and the force can be transmitted to the two pipe segments 21 via the bent ribs, so that the two pipe segments 21 approach each other on the side and compress the flexible cushion 16 on the side, thereby allowing a certain bending of the axis of the tunnel escape duct 2. It should be noted that the rotation process needs to be performed before the circumferential limiting member 12 is fixedly connected to the base 11, in other words, the axial limiting member 13 is connected to the circumferential limiting member 12, the axial limiting member 13 is adjusted until the cushion layer 16 is compressed to a predetermined degree, and then the circumferential limiting member 12 is connected to the base 11.
In some embodiments, the circumferential stop 12 is welded to the base 11.
In some embodiments, the first positioning portion 111 and the second positioning portion 112 are both i-shaped steel. Specifically, the length direction of the I-shaped steel extends along the axial direction of the tunnel escape pipeline 2. The I-shaped steel is used as a common standard part in engineering, has higher strength and lower manufacturing cost, and is beneficial to saving cost.
The embodiment of the present invention further provides a tunnel escape system, please refer to fig. 8, which includes a tunnel escape pipe 2 and the auxiliary fixing device 1 of the tunnel escape pipe 2; the tunnel escape duct 2 passes through the duct space 15 of the auxiliary fixture 1. The tunnel escape pipeline 2 comprises two pipe sections 21, wherein one end of one pipe section 21 in the axial direction is close to one end of the other pipe section 21 in the axial direction; one of the circumferential position-limiting members 12 is disposed outside one of the pipe joints 21, and the other circumferential position-limiting member 12 is disposed outside the other pipe joint 21.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
