Description

Technical Field

[0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a mobile rescue capsule for TBM tunnel excavation which can filter gas. Background Art

[0002] TBM is a mechanical device specially used for tunnel excavation. The working principle of TBM tunnel excavation technology is to cut soil or rock with a rotating cutterhead and transport the excavated soil to the ground through a conveying system. TBM can choose the appropriate type according to different geological conditions, such as slurry balance TBM, earth pressure balance TBM, etc., so as to achieve efficient and safe tunnel excavation.

[0003] The tunnel construction rescue cabin is a safety facility designed specifically for tunnel workers. It is mainly used to provide refuge space in the event of an emergency (such as collapse, fire or gas leakage). It can protect the safety of workers and support their survival needs in an emergency. It plays an important role in improving the emergency rescue capabilities of tunnel construction sites and protecting the lives of workers.

[0004] The Chinese patent application number 202410555405.5 discloses a life-saving capsule for tunnel construction and a method of use, including: a safety life-saving capsule, a plurality of first chutes are provided on both sides of the inner cavity of the safety life-saving capsule at equal distances from top to bottom along the front-to-back direction, and the plurality of first chutes are grouped in pairs, and are divided into a plurality of groups, and limited position chutes are provided on both ends of the front and rear sides of the safety life-saving capsule along the up-down direction; the upper and lower ends of the first guide rod are respectively arranged on the upper and lower sides of the inner cavity of the first chutes. When the device is in use, it can automatically and continuously move its position to adapt to the progress of construction without manual handling, thereby reducing labor intensity and labor costs, and can adapt to changes in the progress of construction more promptly, improve construction efficiency, reduce construction period, and reduce safety risks. At the same time, the device can reduce the impact of collapse on the staff and protect the safety of internal staff.

[0005] During the TBM tunnel excavation process, the life capsule needs to be moved in real time according to the excavation situation. Usually, the track-type movement method can move quickly and stably and has a simple structure. However, this method is troublesome when fixing, and the force-bearing area with the tunnel ground is small, resulting in the capsule being unstable and easily crushed in the event of collapse, and even causing injuries to people in the life capsule; and when the tunnel collapses, harmful gases and dust may be generated, causing external air pollution. It is difficult for trapped people to survive for a long time with only the air and oxygen equipment in the life capsule. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The present invention can take effect when a tunnel collapses through the filtering and separation mechanism. The air outside the cabin is sucked into the air duct through the fan, and then the activated carbon in the filter tank is used to adsorb and filter harmful gases such as carbon monoxide and hydrogen sulfide in the air. The filtered gas enters the treatment pool from the air outlet and is further filtered. Air circulation is formed through the filter mesh port, so that there is safe air in the cabin to ensure the safety of the staff; the present invention uses the structural design of the buffer mechanism. When the tunnel collapses in an emergency, it will first press on the buffer plate, and through the buffering of the buffer spring, the speed of the collapsed object on the top and the impact force on the cabin are reduced, thereby reducing the probability of damage to the cabin; at the same time, the personnel inside the cabin can also understand the external collapse situation through the displacement of the first sliding rod and the first limit plate, providing timely information to the personnel inside the cabin.

[0023] (2) The present invention adopts a structural design of a fixing mechanism. As the TBM tunnel is excavated further, the real-time position of the life capsule needs to be changed at any time. At this time, through the cooperation of the fixing mechanism, the movement or fixation of the capsule can be quickly switched. Specifically, when the capsule needs to be moved, the forward and reverse motors are controlled to rotate so that the lead screw drives the slider to rise along the slide slot. At this time, the support plate is separated from the ground, thereby facilitating the movement of the capsule. When the capsule moves to the appropriate position, the forward and reverse motors are controlled to reverse, the lead screw drives the slider to slide down, and the support plate abuts against the tunnel ground, thereby facilitating the temporary fixation of the capsule.

[0024] (3) The present invention cooperates with the buffer mechanism and the fixing mechanism. When the tunnel collapses in an emergency, the collapsed object presses down the buffer plate, causing the buffer plate to descend. The descent of the buffer plate drives the L-shaped rod to descend synchronously, causing the cone head of the L-shaped rod to pass through the positioning hole and insert into the tunnel ground, thereby automatically fixing the cabin body and preventing the cabin body from being unstable and easily crushed due to the small force-bearing area on the track. At the same time, when the cone head descends, it presses against the inclined surface of the abutment block, causing the abutment block to extend out of the accommodating groove, thereby automatically increasing the force-bearing area of ​​the support plate, further reducing the instability and easy crushing of the cabin body due to the small force-bearing area.

[0025] (4) The present invention adopts a structural design of the support mechanism. When the tunnel is excavated normally, the support plate does not contact the tunnel ground. At this time, the position of the lifeboat can be flexibly changed. When an emergency such as a suspected collapse occurs in the tunnel, after the staff enters the cabin and sits in the seat, the bottom plate will press down the reset spring, so that the support plate contacts the tunnel ground, which can automatically and quickly increase the force-bearing area of ​​the cabin. Through the cooperation of the support plate and the support plate, the stability of the cabin is further improved, and the probability of the cabin being impacted and the personnel inside being injured is reduced.

Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0038] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items.

[0039] Example

[0040] like Figures 1 to 9As shown, a mobile life-saving capsule for TBM tunnel excavation capable of filtering gas comprises a capsule body 100, one end of which is hinged with a hatch 110; two shaft support structures 120 are fixedly installed at both ends of the bottom of the capsule body 100, a rotating shaft 121 is rotatably connected to the shaft support structure 120, and wheels 130 are fixedly connected at both ends of the rotating shaft 121; a track 170 is installed on the tunnel ground, and the wheels 130 are movably abutted on the track 170; the present invention realizes the mobility of the life-saving capsule by abutting the wheels 130 of the capsule body 100 on the track 170, and the real-time position of the capsule body 100 can be quickly moved at any time during the TBM tunnel excavation process.

[0041] A filter separation mechanism 700 is installed at one end of the cabin 100, and the filter separation mechanism 700 includes a fan 710 installed on the side wall of the cabin 100, and the air outlet of the fan 710 is connected to an air duct 720, and an activated carbon slot 721 is opened on the side wall of the air duct 720, and a filter slot 730 is plugged into the activated carbon slot 721, and the bottom of the filter slot 730 is a mesh structure, and activated carbon is placed on the filter slot 730; the air outlet end 740 of the air duct 720 extends into the treatment pool 750, and the treatment pool 750 is fixedly installed on the inner wall of the cabin 100 above the cabin door 110; the diameter of the air outlet end 740 of the air duct 720 is smaller than the diameter of the air duct 720;

[0042] A filter mesh port 760 is also installed at one end of the cabin body 100 opposite to the fan 710 , and the filter mesh port 760 connects the inside and outside of the cabin body 100 .

[0043] The present invention can take effect when a tunnel collapses through the filtering and separating mechanism 700. The air outside the cabin 100 is sucked into the air duct 720 through the fan 710, and then the activated carbon in the filter tank 730 adsorbs and filters harmful gases such as carbon monoxide and hydrogen sulfide in the air. The filtered gas enters the treatment tank 750 from the air outlet end 750 and is further filtered, and an air circulation is formed through the filter mesh port 760, so that the cabin 100 has safe air to ensure the safety of the staff.

[0044] It is worth noting that the fan 710 is powered by an external power supply, which is not described in detail here. By setting the fan 710 above the cabin door 110, the fan 710 can be started as soon as the staff enters the cabin 100; the treatment liquid can be placed in the treatment pool 750 to specifically treat dust and different harmful gases. For example, clean water can be placed to filter and separate the dust in the air.

[0045] A plurality of first sliding holes 150 are symmetrically provided on both sides of the top of the cabin 100, and a buffer mechanism 200 is slidably connected to the first sliding hole 150, and the buffer mechanism 200 includes a first sliding rod 220 slidably connected to the first sliding hole 150; a first limiting plate 221 is fixedly provided at one end of the first sliding rod 220 located inside the cabin 100; a buffer spring 230 is sleeved on the first sliding rod 220, and two ends of the buffer spring 230 are respectively fixedly connected to the first limiting plate 221 and the cabin 100; and a buffer plate 210 is fixedly connected to one end of the first sliding rod 220 located outside the cabin 100.

[0046] The present invention adopts the structural design of the buffer mechanism 200. When the tunnel collapses in an emergency, it will first press on the buffer plate 210. Through the buffering of the buffer spring 230, the speed of the collapsed object on the top and the impact force on the cabin 100 are weakened, thereby reducing the probability of damage to the cabin 100; at the same time, the personnel inside the cabin 100 can also understand the external collapse situation through the displacement of the first sliding bar 220 and the first limiting plate 221, providing timely information for the personnel inside the cabin 100.

[0047] Furthermore, a plurality of fixing mechanisms 300 are evenly arranged on the outer walls of both sides of the cabin body 100, and the fixing mechanisms 300 include a slide groove 310, and the slide groove 310 is vertically fixed on the outer wall of the cabin body 100; a forward and reverse motor 330 is fixedly installed on the top wall of the slide groove 310, and the output end of the forward and reverse motor 330 passes through the slide groove 310 and extends into the interior of the slide groove 310; a screw rod 320 is fixedly connected to the output end of the forward and reverse motor 330, and the end of the screw rod 320 away from the forward and reverse motor 330 is rotatably connected to the bottom wall of the slide groove 310; a slider 340 is threadedly connected to the screw rod 320, and the slider 340 is slidably connected to the slide groove 310; an L-shaped frame 350 is fixedly connected to one side of the slider 340, and the end of the L-shaped frame 350 away from the slider 340 is fixedly connected to the support plate 400.

[0048] Furthermore, when the forward and reverse motor 330 controls the screw rod 320 to rotate and causes the slider 340 to slide down, the support plate 400 can abut against the tunnel ground.

[0049] Through the structural design of the fixing mechanism 300 of the present invention, as the TBM tunnel is excavated deeper, the real-time position of the life capsule needs to be changed at any time. At this time, through the cooperation of the fixing mechanism 300, it can be quickly switched when the capsule 100 is moved or fixed; specifically, when the capsule 100 needs to move, the forward and reverse motors 300 are controlled to rotate, so that the screw rod 320 drives the slider 340 to rise along the slide groove 310, and the support plate 400 is now separated from the ground, thereby facilitating the movement of the capsule 100; when the capsule 100 moves to the appropriate position, the forward and reverse motors 300 are controlled to reverse, the screw rod 320 drives the slider 340 to slide down, and the support plate 400 abuts against the tunnel ground, thereby facilitating the temporary fixation of the capsule 100.

[0050] It is worth noting that the forward and reverse motor 300 of the present invention can rotate forward or reverse, and is powered by an external power supply. This is prior art and will not be described in detail herein.

[0051] Furthermore, a plurality of L-shaped rods 900 are symmetrically fixedly connected on both sides of the buffer plate 210; a positioning hole 351 is vertically penetrated through the L-shaped frame 350 and the support plate 400, and a cone head 910 is provided at one end of the L-shaped rod 900 away from the buffer plate 210; the L-shaped rod 900 is inserted into the corresponding positioning hole 351 and is slidably connected to the positioning hole 351.

[0052] Furthermore, when the buffer plate 210 is pressed downward, the cone head 910 can pass through the positioning hole 351 and be inserted into the tunnel floor.

[0053] It is worth noting that when the tunnel collapses, the collapsed objects fall onto the buffer plate 210, thereby pressing the buffer plate 210 downward.

[0054] Furthermore, two receiving grooves 410 are symmetrically provided on both sides of the support plate 400, and two spring grooves 420 are symmetrically provided on both sides of the interior of the receiving groove 410; a second slide rod 440 is fixedly provided in the middle of the interior of the spring groove 420, and the two second slide rods 440 are slidably connected with a support block 460, and the support block 460 is located in the receiving groove 410; a return spring 430 is sleeved on the slide rod 440, and the return spring 430 is located in the spring groove 420; the two ends of the return spring 430 are respectively fixedly connected to the interior of the spring groove 420 and the support block 460.

[0055] Furthermore, a connecting slot 450 is provided in the middle of the interior of the accommodating slot 410, and the connecting slot 450 is connected to the positioning hole 351; an abutment block 461 is fixedly provided in the middle of one side of the supporting block 460, and the upper surface of the abutment block 461 is a slope structure; the two abutment blocks 461 extend into the corresponding connecting slots 450 and abut against each other.

[0056] It is worth noting that when the cone head 910 passes through the positioning hole 351 and is inserted into the tunnel ground, the cone head 910 will press against the inclined structure of the abutment block 461, so that the abutment block 461 extends out from the accommodating groove 410, thereby increasing the supporting force area of ​​the support plate 400.

[0057] Furthermore, two second sliding holes 462 are symmetrically formed through the support block 460 , and the second sliding holes 462 are slidably connected to the corresponding second sliding rods 440 .

[0058] The present invention cooperates with the buffer mechanism 200 and the fixing mechanism 300. When the tunnel collapses in an emergency, the collapsed object presses down the buffer plate 210, causing the buffer plate 210 to descend; the descent of the buffer plate 210 drives the L-shaped rod 900 to descend synchronously, causing the cone head 910 of the L-shaped rod 900 to pass through the positioning hole 351 and insert into the tunnel ground, thereby automatically further fixing the cabin 100 and preventing the cabin 100 from being unstable and easily crushed due to the small force area on the track 170; at the same time, when the cone head 910 descends, it will press against the inclined surface of the abutment block 461, causing the abutment block 461 to extend out of the accommodating groove 410, thereby automatically increasing the force area of ​​the support plate 400, further reducing the instability and easy crushing of the cabin 100 due to the small force area.

[0059] Furthermore, a plurality of third sliding holes 160 are evenly penetrated through the bottom of the cabin 100, and a support mechanism 500 is slidably connected to the third sliding hole 160; the support mechanism 500 includes a third sliding rod 520 slidably connected to the third sliding hole 160; the third sliding rod 520 and one end located outside the cabin 100 are jointly fixedly connected to a support plate 510; the third sliding rod 520 and one end located inside the cabin 100 are jointly fixedly connected to a bottom plate 540, and a plurality of seats 600 are fixedly installed on the bottom plate 540; a second return spring 530 is sleeved on the third sliding rod 520, and the two ends of the second return spring 530 are respectively fixedly connected to the bottom plate 540 and the cabin 100; when there is no one on the seat 600, the support plate 510 does not abut against the tunnel ground; when there is someone on the seat 600, the support plate 510 abuts against the tunnel ground.

[0060] Through the structural design of the support mechanism 500 of the present invention, when the tunnel is excavated normally, the support plate 510 does not abut against the tunnel ground, and the position of the lifeboat can be flexibly changed at this time. When an emergency such as a suspected collapse occurs in the tunnel, after the staff enters the cabin 100 and sits in the seat 600, the bottom plate 540 will press down the return spring 530 to make the support plate 510 abut against the tunnel ground, thereby automatically and quickly increasing the force-bearing area of ​​the cabin 100. Through the cooperation of the support plate 510 and the support plate 400, the stability of the cabin 100 is further improved, and the probability of the cabin 100 being impacted and the internal personnel being injured is reduced.

[0061] It is worth noting that the seat 600 may be provided with protective equipment such as safety belts to fully protect the staff, which is a conventional setting and will not be described in detail here.

[0062] Furthermore, a switch panel 140 is fixedly mounted on the side wall of the cabin 100 , and the switch panel 140 is electrically connected to the forward and reverse motor 330 ; a storage box 800 is installed inside the cabin 100 ; and pull rings are fixedly mounted on both ends of the cabin 100 .

[0063] The forward and reverse motor 330 is controlled by the switch panel 140, and rescue equipment and emergency supplies such as food, medicine, and oxygen supply equipment are placed in the storage box 800; the pull ring can be pulled by external equipment during the TBM tunnel excavation process, thereby facilitating the rapid movement of the cabin 100.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
