Description

Technical Field

[0001] The utility model belongs to the field of tunnel escape devices, and particularly relates to an escape device and an escape system for tunnels. Background Technique

[0002] With the development and progress of transportation construction, the proportion of tunnel projects in transportation engineering construction projects is increasing continuously. Due to the complex geological conditions in tunnel construction, collapse accidents often occur. When the construction workers in the tunnel find signs of tunnel collapse or the collapse has already started, they are in a dangerous situation where there is no way to escape and nowhere to hide, posing a great threat to the lives of the construction workers in the tunnel.

[0003] Currently, during domestic tunnel construction, measures such as excavating the collapsed body or preventing steel pipes are usually taken to rescue the trapped personnel. However, due to the need for tunnel cross-section design and construction, the diameter of traditional escape pipes is often controlled at about 800 mm. Therefore, during emergency escape, construction workers can only crawl on the escape vehicle and slide the escape vehicle by hand to escape. Moreover, the escape pipe is easily misaligned up and down due to the uneven tunnel floor, seriously affecting the escape speed and increasing the casualty probability invisibly. In addition, there is also a risk that the escape passage may be penetrated by the collapsed objects. At this time, the collapsed objects may directly hit the escape personnel, posing a possibility of secondary injury. In addition, traditional escape vehicles are prone to roll over in the pipeline, lacking a stabilizing device and having no protective measures, which may cause secondary injury to personnel and other problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an escape device and an escape system for tunnels that can provide secondary protection for trapped personnel and improve the walking stability in the escape passage.

[0005] The utility model provides an escape device for tunnels, which includes a vehicle chassis, a walking driving mechanism and an escape cockpit arranged on the vehicle chassis;

[0006] The vehicle chassis includes a frame body and a plurality of groups of walking wheels arranged on the frame body along the length direction, and the walking driving mechanism is used to drive at least one group of the walking wheels;

[0007] The escape cockpit includes a cylinder body with openings at both ends, and auxiliary wheels are arranged on the outer wall of the cylinder body;

[0008] The walking wheels and the auxiliary wheels are used to fit with the inner wall of the escape passage in the tunnel.

[0009] Furthermore, a plurality of the auxiliary wheels are arranged in the circumferential direction of the cylinder body, and multiple groups are arranged in the axial direction of the cylinder body.

[0010] Furthermore, the cylinder body includes a cylindrical protective cover and a reinforcing frame structure arranged outside the protective cover.

[0011] Furthermore, the reinforcing frame structure includes a plurality of reinforcing rings arranged at equal intervals along the axial direction on the outer wall of the protective cover.

[0012] Furthermore, the reinforcing frame structure further includes a plurality of transverse skeletons arranged in a circular array on the plurality of reinforcing rings with the axis of the cylinder body as the axis.

[0013] Furthermore, the auxiliary wheels are fixedly arranged on the transverse skeletons.

[0014] Furthermore, the length of the cylinder body can accommodate multiple people.

[0015] Furthermore, the traveling driving mechanism is arranged on the opening side of the cylinder body;

[0016] The traveling driving mechanism includes a driving motor, a reducer, a battery, a switch, and a shift controller. The driving motor is connected to the reducer, the output end of the reducer is connected to the traveling wheels, the battery is used to supply power to the driving motor, the switch is used to control the starting of the driving motor, and the shift controller is used to control the forward and reverse rotation of the reducer.

[0017] Furthermore, the escape device for tunnels of the present invention further includes an alarm device arranged on the vehicle chassis and a lighting device arranged at the front end of the vehicle chassis.

[0018] The present invention also provides an escape system for tunnels, which includes an escape passage arranged in the tunnel and the above-mentioned escape device for tunnels arranged in the escape passage.

[0019] The beneficial effects of the present invention are as follows: By setting the escape cabin as a cylinder structure adapted to the escape passage, the openings at both ends can be used for trapped persons to enter and exit the cylinder body, facilitating the trapped persons to enter and exit the escape cabin. The trapped persons are carried inside the cylinder body, which can avoid frictional damage caused by the contact between the trapped persons and the inner wall of the escape passage during the escape process. At the same time, it can form a second layer of protection outside the escape passage. When the external escape passage is penetrated by the collapsed objects, it can prevent the collapsed objects inside the penetrated escape passage from directly hitting the escape personnel, improving the success rate of escape. In addition, according to the length of the cylinder body, multiple trapped persons can be carried at the same time. In addition, by arranging auxiliary wheels on the side wall of the cylinder body, the walking stability of the escape device can also be improved, and the success rate of escape is also improved.

[0028] As Figure 1 - Figure 2 shown, the present utility model provides an escape device and an escape system for a tunnel, including a vehicle chassis 1, a traveling drive mechanism 2 and an escape cockpit 3 provided on the vehicle chassis 1;

[0029] The vehicle chassis 1 includes a frame body 11 and a plurality of sets of traveling wheels 12 arranged on the frame body 11 along the length direction. The traveling wheels 12 are used to fit against the inner wall of the escape passage 6 in the tunnel, driving the vehicle chassis 1 to move in the escape passage 6. The traveling drive mechanism 2 is used to drive at least one set of the traveling wheels 12, thereby realizing the active movement of the vehicle chassis 1 without the trapped persons having to manually drive the vehicle chassis 1 to move. Preferably, the traveling wheels 12 are pneumatic tires, which can improve the degree of fitting against the inner wall of the escape passage 6;

[0030] The escape cockpit 3 includes a cylinder body 31 with openings 3111 at both ends. The inside of the cylinder body 31 is used to carry the trapped persons, and the openings 3111 at both ends can allow the trapped persons to enter and exit the cylinder body 31. Carrying the trapped persons inside the cylinder body 31 can prevent the trapped persons from contacting the inner wall of the escape passage 6 during the escape process and causing frictional damage. At the same time, it can form a second layer of protection outside the escape passage 6. When the external escape passage 6 is penetrated by the collapsed objects, it can prevent the collapsed objects inside the penetrated escape passage 6 from directly hitting the escape personnel, improving the success rate of escape. In addition, according to the length of the cylinder body 31, multiple trapped persons can be carried at the same time. An auxiliary wheel 32 is provided on the outer wall of the cylinder body 31. The auxiliary wheel 32 is used to fit against the inner wall of the escape passage 6 in the tunnel. Preferably, the auxiliary wheel 32 is tangent to the inner wall of the escape passage 6. When the traveling wheels 12 drive the escape device for the tunnel to move in the escape passage 6, the auxiliary wheel 32 can prevent the overall escape device from shaking or tipping over, so as to realize the stable driving of the escape device on the inner wall of the escape passage 6.

[0031] That is, in the present utility model, the escape cabin 3 is set as a cylindrical body 31 structure adapted to the escape passage 6, and the openings 3111 at both ends can be used for the trapped persons to enter and exit the cylindrical body 31, facilitating the trapped persons to enter and exit the escape cabin 3. The trapped persons carried inside the cylindrical body can avoid frictional damage caused by contact between the trapped persons and the inner wall of the escape passage 6 during the escape process. At the same time, using the cylindrical body 31 to carry the trapped persons can form a second layer of protection outside the escape passage 6, preventing the collapsed objects inside the escape passage 6 from directly hitting the escape personnel when the external escape passage 6 is penetrated by the collapsed objects, thereby improving the success rate of escape. In addition, according to the length of the cylindrical body 31, multiple trapped persons can be carried at the same time. In addition, by providing auxiliary wheels 32 on the side wall of the cylindrical body 31, the walking stability of the escape device can be improved, and the success rate of escape can also be improved.

[0032] In one embodiment, a plurality of the auxiliary wheels 32 are circumferentially arranged on the cylindrical body 31, and multiple groups are axially arranged on the cylindrical body 31, thereby increasing the contact support points between the cylindrical body 31 and the inner wall of the escape passage 6, and further improving the stable travel of the escape device on the inner wall of the escape passage 6.

[0033] In one embodiment, the cylindrical body 31 includes a cylindrical protective cover 311 and a reinforcing skeleton structure arranged outside the protective cover 311, thereby improving the structural strength of the cylindrical body 31 and enhancing its safety. Preferably, the protective cover 311 is made of endurance plate, which has good impact resistance and load-bearing capacity. Preferably, the thickness of the protective cover 311 is 5 mm to provide sufficient protection ability.

[0034] In one embodiment, the reinforcing skeleton structure includes a plurality of reinforcing rings 312 equidistantly arranged along the axial direction on the outer wall of the protective cover 311 to improve the longitudinal circumferential strength of the protective cover 311. Preferably, the reinforcing rings 312 are made of DN20 galvanized pipes, which have good corrosion resistance, can be used in harsh environments and maintain a long service life, and are suitable for devices such as escape devices that are idle for a long time.

[0035] In one embodiment, the reinforcing skeleton structure further includes a plurality of transverse skeletons 313 arranged in a circular array on the plurality of reinforcing rings 312 with the axis of the cylindrical body 31 as the axis. By adding the transverse skeletons 313, the transverse axial strength of the protective cover 311 can be improved. Preferably, the transverse skeletons 313 are also made of DN20 galvanized pipes. Preferably, the transverse skeletons 313 and the reinforcing rings 312 are fixed to each other by welding.

[0036] In one embodiment, the auxiliary wheels 32 are fixedly arranged on the transverse skeletons 313, simplifying the installation difficulty and ensuring that the multiple auxiliary wheels 32 arranged along the axial direction of the cylindrical body 31 are in a straight line.

[0037] In one embodiment, the length of the cylinder 31 can accommodate multiple people, thereby increasing the number of people who can escape at one time in the utility model. When only one person needs to escape, the riding space can also be increased, thereby improving the success rate of escape.

[0038] In one embodiment, the travel drive mechanism 2 is arranged on one side of the opening 3111 of the cylinder 31, so that the trapped person can operate and control the travel drive mechanism 2 in the cylinder 31 conveniently;

[0039] The walking drive mechanism 2 includes a driving motor 21, a reducer 22, a battery 23, a switch 24 and a shift controller 25. The driving motor 21 is connected to the reducer 22, and the output end of the reducer 22 is connected to the walking wheel 12. The battery 23 is used to supply power to the driving motor 21. The switch 24 is used to control the pneumatic operation of the driving motor 21. The shift controller 25 is used to control the forward and reverse rotation of the reducer 22.

[0040] This embodiment can control the escape device to move forward and backward, solving the problem that the traditional escape device cannot turn around, and then realizing that after escaping from the danger zone, the escape device can re-enter the danger zone to rescue other escapees. In specific use, when facing a situation where multiple people are trapped and need to escape, this solution can first transport more than two people to a safe area, then press the control shift controller 25 to switch to reverse gear, drive to other escapees and take them away from the danger zone, and repeat this operation until all trapped people are taken away from the danger zone.

[0041] In one of the embodiments, the tunnel escape device also includes an alarm device arranged on the vehicle chassis 1 and a lighting device 4 arranged at the front end of the vehicle chassis 1, so that the trapped persons can conveniently observe the situation in the escape passage 6 and conveniently remind other construction workers and external rescue personnel.

[0042] In one of the embodiments, a first aid kit 5 may be provided on the vehicle chassis 1 to contain common first aid tools and first aid supplies, so as to provide treatment to injured trapped persons.

[0043] The utility model also provides a tunnel escape system, including an escape passage 6 arranged in the tunnel and the above-mentioned tunnel escape device arranged in the escape passage 6. Preferably, the cylinder 31 of the escape device is away from the opening 3111 on the side of the travel drive mechanism 2 toward the side of the escape passage 6 located in the tunnel, so as to facilitate the trapped persons to quickly enter the cylinder 31 without any obstruction.

[0044] Specific working principle of the present utility model: During tunnel construction, place the head of this escape device facing outward at the innermost end of the escape passage 6 (statutory inner diameter 800 mm). When a danger occurs, construction workers can quickly drill into the built-in protective cover 311 of this device through the opening 3111, turn on the shift controller 25 to the forward gear and press the start switch 24. While emitting a beeping alarm sound and turning on the lighting device 4, this device will quickly drive away from the dangerous area along the escape passage 6. During this driving process, the moving direction of the traveling wheels 12 at the lower end of the vehicle chassis 1 is the main movement direction of this emergency escape vehicle, and the auxiliary wheels 32 move along the inner wall of the escape passage 6 to prevent this escape device from tipping over in the escape passage 6, playing a role in stabilizing the forward movement of this escape passage 6 along the main movement direction. The alarm device can warn other construction workers to quickly drill into the escape passage 6 to escape and warn external personnel to carry out rescue and support in the first time. After the first batch of people safely escape to the safe area, leave one person to start the shift controller 25, change the forward gear to the reverse gear, and the device will drive back along the escape passage 6 to rescue other trapped escape personnel, and repeat this operation until all personnel are safely rescued. When a collapse object penetrates the escape passage 6, the combination of the built-in protective cover 311 and the reinforced skeleton structure can also ensure that the escape personnel are not injured; the first aid kit 5 is equipped with common first aid tools and first aid supplies to cope with other emergencies. In summary, this escape device can significantly improve the escape efficiency of construction workers in the tunnel in case of danger, increase the probability of the construction workers' escape from danger, and save lives in times of crisis.

[0045] The above is only this embodiment and does not impose any limitations on the present utility model. Any person skilled in the art, without departing from the scope of the technical solution of the present utility model, can make many possible changes, modifications or equivalent changes and modifications to the technical solution of the present utility model using the technical content disclosed above as equivalent embodiments. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
