[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides a detachable tunnel escape pipeline fixing and protecting device, such as Figure 1-Figure 2 As shown, it includes four fixed frame longitudinal rods 1, which are located on the outside of the escape pipe 7 and are arranged parallel to each other. Fixed frame transverse rods 2 are installed on the upper and lower sides of the two end heads of the escape pipe 7, and fixed frame vertical rods 3 are installed on the left and right sides of the two end heads of the escape pipe 7. A fixed frame connecting steel plate 5 is installed on the outside of the end of the fixed frame longitudinal rod 1, and the two detachable tunnel escape pipe fixing protection devices are connected by the fixed frame connecting steel plate 5.
[0021] In this embodiment, the number of the fixed frame transverse rods 2 and the number of the fixed frame vertical rods 3 are both four.
[0022] Specifically, threaded holes are provided on the surface of the fixed frame connecting steel plate 5 , and the fixed frame connecting steel plate 5 is connected to the end of the fixed frame longitudinal rod 1 by high-strength bolts 6 , so as to facilitate the connection between the fixed frame longitudinal rods 1 .
[0023] Furthermore, a fixed frame angle brace 4 is installed on the inner side between the fixed frame transverse rod 2 and the fixed frame vertical rod 3. The fixed frame angle brace 4 is a right-angled triangle structure, which is convenient for positioning and supporting the outer side of the escape duct 7.
[0024] Furthermore, the hypotenuse of the fixed frame angle brace 4 is tangent to the outer side of the escape duct 7, and the two right-angled sides of the fixed frame angle brace 4 are respectively welded and fixed to the fixed frame transverse rod 2 and the fixed frame vertical rod 3 to ensure the stability of the equipment.
[0025] Furthermore, a gasket 41 is installed on the outer side of the oblique side of the fixed frame corner brace 4 to provide a certain buffering effect.
[0026] Furthermore, the fixed frame longitudinal rods 1 and the fixed frame transverse rods 2 are both I-beam structures to improve the supporting strength.
[0027] Furthermore, a pressure plate 8 is installed on the outer wall of the escape duct 7 near the fixed frame longitudinal rod 1 and the fixed frame transverse rod 2 to prevent the outer wall of the escape duct 7 from being worn.
[0028] When the detachable tunnel escape pipe fixing and protection device of the utility model is used, firstly, four fixing frame longitudinal rods 1 are arranged in parallel on the outside of the escape pipe 7, providing a basic support structure for the entire fixing and protection device. These longitudinal rods are connected together by fixing frame connecting steel plates 5 and high-strength bolts 6, ensuring the stability and strength of the entire device.
[0029] Next, the two ends of the escape pipe 7 are provided with fixed frame transverse rods 2 on the upper and lower sides, and fixed frame vertical rods 3 on the left and right sides. These transverse and vertical rods, together with the longitudinal rods, form a complete fixed frame, in which the escape pipe 7 is tightly fixed.
[0030] In order to further enhance the fixing effect, a fixing frame angle brace 4 is installed on the inner side between the fixing frame transverse rod 2 and the fixing frame vertical rod 3. These angle braces are in a right-angled triangle structure, and their hypotenuse is tangent to the outer side of the escape pipe 7, providing additional support for the pipe. At the same time, the two right-angle sides of the angle brace are respectively welded and fixed to the transverse rod and the vertical rod, ensuring the firmness of the entire fixing frame.
[0031] Gaskets 41 are also installed on the outer side of the oblique side of the fixed frame corner brace 4. These gaskets can play a certain buffering role when the pipeline is subjected to external impact, protecting the pipeline from damage.
[0032] In addition, the longitudinal members 1 and the transverse members 2 of the fixed frame are both made of I-beam structure, which has high strength and load-bearing capacity and can ensure that the fixed protection device will not be deformed or damaged when subjected to external impact.
[0033] Finally, in order to prevent the outer wall of the escape pipe 7 from being worn during the fixing process, a pressure plate 8 is installed on the outer wall of the pipe near the longitudinal rod 1 and the transverse rod 2 of the fixing frame. These pressure plates can effectively reduce the direct contact between the pipe and the fixing frame, thereby extending the service life of the pipe.
