[0002] With the increasing maturity of highway tunnel construction technology in my country, the relevant design theory and construction technology of tunnels under complex and changeable geological conditions have achieved certain results. However, collapse accidents occur frequently during tunnel construction, and construction safety issues are also extremely severe. At present, the escape and risk avoidance in the process of domestic tunnel construction mostly adopts the method of laying escape pipes between the secondary lining and the face. Due to the needs of tunnel section design and construction, the diameter of the escape pipe is often controlled at about 800mm. Therefore, construction personnel can only crawl on the escape vehicle and slide the escape vehicle by hand to escape in an emergency. In addition, the escape pipe is easily dislocated up and down due to the unevenness of the tunnel ground, which seriously affects the escape speed and increases the probability of casualties. Therefore, it is necessary to upgrade and transform the existing escape equipment to further improve the escape rate of tunnel construction. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1-3 As shown, a practical emergency escape pipe vehicle device in a tunnel includes an escape pipe 1, an escape pipe vehicle 2, an air supply pipe 3, and an electric control system 4.

[0028] The escape pipe 1 is provided with a pipe support 5 outside, and the top of the escape pipe 1 is provided with a pre-buried iron 101. The escape pipe 1 is a reinforced concrete structure or an iron pipe structure.

[0029] The escape pipe vehicle 2 is arranged in the escape pipe 1. A magnetic attraction device 201 is arranged on the top of the escape pipe vehicle 2. Wheels 202 and a driving motor 203 for driving the wheels 202 to rotate are arranged on the bottom of the escape pipe vehicle 2.

[0030] The air supply duct 3 includes a high-pressure air supply rubber tube 301 and a high-pressure air supply steel tube 302. The high-pressure air supply rubber tube 301 is arranged in the escape duct 1, and the two ends of the high-pressure air supply rubber tube 301 are respectively connected to the high-pressure air supply steel tube 302. The high-pressure air supply rubber tube 301 and the high-pressure air supply steel tube 302 are connected by a tube connector 6.

[0031] The electric control system 4 includes an in-vehicle electric control device 41 and an out-vehicle electric control system 42. The in-vehicle electric control device includes a central processing unit 1 411, a communication module 1 412, a drive motor control module 413, a magnetic device control module 414, and a power module 415. The central processing unit 1 411 is respectively connected to the communication module 1 412, the drive motor control module 413, the magnetic device control module 414, and the power module 415. The out-vehicle electric control system 42 includes a central processing unit 2 421, a communication module 2 422, an air supply control module 423, and a pipe connector disconnection control module 424. The central processing unit 2 421 is respectively connected to the communication module 2 422, the air supply control module 423, and the pipe connector disconnection control module 424.

[0032] The communication module 1 412 and the communication module 2 422 are used to realize real-time wireless communication between the personnel in the escape pipe vehicle 2 and the external personnel. The drive motor control module 413 is used to control the drive motor 203 to control the rotation of the wheel 202. The magnetic device control module 414 is used to control the magnetic device 201 to attract the embedded iron 101 and lift the escape pipe vehicle 2. The power module 415 is used to supply power to the in-vehicle electric control device 41 and the drive motor 203. The air supply control module 423 is used to control the air supply direction and air supply flow rate.

[0033] The outer surface of the escape duct 1 is provided with a plurality of pressure sensors 7, and the pressure sensors 7 are connected to the central processor 2 421. When the pressure sensor 7 detects the external heavy pressure of the escape duct 1, the pipe connector disconnection control module 424 controls the pipe connector 6 to disconnect, or the pipe connector disconnection control module 424 is actively controlled by an external person to control the pipe connector 6 to disconnect. When the pipe connector 6 is disconnected, due to the elastic deformation of the high-pressure air supply rubber tube 301 and the high-pressure air delivered by the high-pressure air supply steel tube 302, the high-pressure air supply rubber tube 301 is automatically removed from the pipe mouth of the high-pressure air supply steel tube 302, and the pipe mouth of the high-pressure air supply rubber tube 302 can smoothly supply air to the escape duct 1.

[0034] A position sensor 8 is provided at the bottom of the escape pipe vehicle 2, and a plurality of proximity switches 9 corresponding to the position sensor 8 are provided along the escape pipe 1 in the escape pipe 2.

When the position sensor 8 passes the proximity switch 9, the proximity switch 9 sends a corresponding position signal, thereby locating the trapped section of the trapped person, which is convenient for rescue.

[0035] The escape tube vehicle 2 comprises a vehicle body, a front door and a rear door. The vehicle body is tubular. The front door and the rear door are respectively hinged to the vehicle body and locked by a locking mechanism.

[0038] 2. A position sensor is installed on the pipeline vehicle, and a corresponding proximity switch is set in the escape pipeline. When the position sensor passes the proximity switch, the proximity switch sends a corresponding position signal, thereby locating the trapped section of the trapped person, which is convenient for rescue;

[0039] 3. During the operation of the escape pipe vehicle, the pre-buried iron can be absorbed by the magnetic device on the top to lift the escape pipe vehicle, so that the escape pipe vehicle can be pushed by wind without excessive friction with the escape pipe;

[0040] 4. When the pressure sensor detects the external heavy pressure of the escape duct, the pipe connector disconnection control module controls the pipe connector to disconnect, or an external person actively controls the pipe connector disconnection control module to control the pipe connector to disconnect, so as to supply air into the escape duct through the high-pressure air supply steel pipe. Firstly, the oxygen content in the escape duct can be guaranteed to prevent the trapped personnel from lack of oxygen. Secondly, the escape duct vehicle can be driven to run in combination with the magnetic suction device on the top of the escape duct vehicle.

[0041] 5. The driving motor drives the wheels to rotate, thereby driving the escape pipeline vehicle to run, which can save the physical strength of the trapped people;

[0042] 6. In the absence of wind power and power drive of the wheels, the trapped persons can lie down in the escape tube vehicle and push the escape tube vehicle with their hands and feet. During the operation of the escape tube vehicle, the magnetic suction device on the top of the escape tube vehicle can absorb the embedded iron and lift the escape tube vehicle, which is convenient for the trapped persons to push the escape tube vehicle, saving their physical strength and facilitating escape and rescue.
