Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, in particular to a mobile tunnel support cabin capable of supplying oxygen. Background Art

[0002] Tunnel construction is a high-risk job, especially when the geological conditions are bad and the rock quality is poor. Conventional construction methods can easily cause landslides. Tunnel construction requires the installation of a safety cabin to ensure the safety of construction workers in the tunnel and reduce casualties among construction workers.

[0003] At present, China's patent application number: CN201510166924.3 discloses a tunnel lifeboat structure, including a cabin body, a cabin door and an escape door hinged on the cabin body, a track connected to the bottom of the cabin body, and a ventilation system, an oxygen supply system, an air purification system, an environmental monitoring system, a communication system and a survival support system are arranged in the cabin body. By configuring the ventilation system, oxygen supply system, air purification system, environmental monitoring system, communication system and survival support system in the cabin body, a safe refuge space can be provided for survivors after an accident occurs, which can buffer the rescue time and effectively reduce casualties caused by the disaster.

[0034] The mobile tunnel support cabin capable of supplying oxygen of the present invention has the following working principle:

[0035] First, the support cabin 1 is moved by the walking crawler 2 so as to be moved into the tunnel under construction for use of the present design;

[0036] Second, when the air supply pipe in the tunnel works normally, open the second solenoid valve pipe 85 and the third solenoid valve pipe 891, close the first solenoid valve pipe 83 and the fourth solenoid valve pipe 892, so that the air in the air supply pipe passes through the three-stage filter 86, the pressure regulating valve 87 and the muffler 88, and then is discharged from the third solenoid valve pipe 891 into the interior of the support cabin 1 for use;

[0037] Third, when danger occurs and the air supply duct in the tunnel is blocked, the gas in the external environment is first monitored by the monitoring system on the security cabin 1. When there is no harmful gas, the first solenoid valve tube 83 and the fourth solenoid valve tube 892 are opened and the second solenoid valve tube 85 and the third solenoid valve tube 891 are closed. Then, the first motor 816 is controlled to start. Under the action of the first motor 816, the gear 815 moves on the rack 814, and the connecting piece 817 moves in the slide groove 813 to drive the first stopper 818 to shift. When the first stopper 818 shifts, the second stopper 8110 is driven to move and slide in the slot frame 812 through the pull rod 819, so that the second stopper 8110 and the first stopper 818 move into the top side of the outer frame seat 811.

[0038] Fourth, control and start the second motor 823. Under the action of the second motor 823, the eccentric rod 824 rotates inside the support frame 822. When the eccentric rod 824 rotates, the shift block 828 is driven to make a reciprocating lateral movement inside the sleeve 8210 through the push frame 827. The shift block 828 drives the push-pull rod 8294 to stably move left and right lateral movements inside the support block 8211. When the push-pull rod 8294 moves to the left, the second one-way valve plate 8296 and the third one-way valve plate 8297 are opened, and the first one-way valve plate 8295 and the fourth one-way valve plate 8296 are opened. 98 is closed, and the external air is sucked in and discharged through the lower pipe 8293. When the push-pull rod 8294 moves to the right, the first one-way valve plate 8295 and the fourth one-way valve plate 8298 are opened, and the second one-way valve plate 8296 and the third one-way valve plate 8297 are closed, and the external air is sucked in and discharged through the lower pipe 8293. The air passes through the first solenoid valve pipe 83 and enters the three-stage filter 86, the pressure regulating valve 87 and the muffler 88, and then enters the diffused oxygen generator 810 from the fourth solenoid valve pipe 892 for oxygen production, so that the oxygen is discharged into the support cabin 1 for use;

[0039] Fifth, while the diffusion oxygen concentrator 810 is generating oxygen, the third motor 82610 can be controlled to start. Under the action of the third motor 82610, the bevel gear rotating rod 8268 drives the threaded rod 8265 to move inside the internal thread rotating block 8262 through the cooperation with the bevel gear 8267, so that the internal thread rotating block 8262 drives the slider 8263 to move inside the arc frame 8264 to increase the height position of the supporting rotating rod 8261, thereby changing the amplitude and speed of the swing of the push frame 827 driven by the rotating frame 825, so that the amplitude and speed of the lateral movement of the push-pull rod 8294 in the sleeve 8292 are accelerated, thereby improving the efficiency of absorbing external air and improving the oxygen generation effect of the diffusion oxygen concentrator 810.
