[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] The present application embodiment discloses a highly efficient oxygen supply and ventilation system based on high altitude tunnel construction. Figure 1 The high-efficiency oxygen supply and ventilation system based on high-altitude tunnel construction includes an air exchange system, a support frame 1, an oxygen tank 2 and a hanging plate 4. The air exchange system is the same as that in the related art and will not be described in detail here; to ensure ventilation of the tunnel. The support frame 1 is used for sliding connection on the slideway, and the sliding direction of the support frame 1 is parallel to the excavation direction of the tunnel. The driving method of the support frame 1 is also the same as that in the related art and will not be described in detail here. There are multiple oxygen tanks 2 to ensure oxygen supply for multiple people; multiple oxygen tanks 2 are installed on the support frame 1, and the multiple oxygen tanks 2 are arranged in sequence along the sliding direction of the support frame 1. Both ends of the oxygen tank 2 are connected to a connecting pipe 3, and an electromagnetic valve (not marked in the figure) is installed on the connecting pipe 3. The electromagnetic valve is used to wirelessly connect to the control switch set on the oxygen mask.

[0026] Reference Figure 1 and Figure 2 Two hanging plates 4 are provided, and the two hanging plates 4 are detachably fixed on the opposite sides of the support frame 1 by means of bolts, screws, etc. The length direction of the hanging plate 4 is parallel to the sliding direction of the support frame 1, the hanging plate 4 is located below the support frame 1, and the oxygen tank 2 is located between the hanging plates 4 on both sides; a sliding block 5 is penetrated through the hanging plate 4 for sliding in the horizontal direction, and the cross-section of the sliding block 5 is cross-shaped, and the sliding direction of the sliding block 5 is parallel to the excavation direction of the construction tunnel; the sliding block 5 on each hanging plate 4 corresponds to the oxygen tank 2 one by one, and the multiple sliding blocks 5 on each hanging plate 4 are arranged in the horizontal direction. Furthermore, the arrangement direction of the multiple sliding blocks 5 on each hanging plate 4 is perpendicular to the sliding direction of the sliding block 5, so that the sliding block 5 has a large moving range in the construction direction.

[0027] Reference Figure 1 and Figure 2 A gas pipe 6 is fixedly provided on each sliding block 5, one end of the gas pipe 6 is connected to the connecting pipe 3 close to one side of the corresponding oxygen tank 2, and the other end is used to connect to the oxygen mask. The length from one end of the gas pipe 6 close to the corresponding connecting pipe 3 to the sliding block 5 is greater than the vertical distance from the connecting pipe 3 to the hanging plate 4.

[0028] When in use, the support frame 1 can drive the oxygen tank 2 to move with the construction workers. When oxygen inhalation is needed, the construction workers wear the oxygen mask connected to the lower end of the gas pipe 6, and turn on the corresponding solenoid valve by operating the control switch on the oxygen mask. Since the sliding block 5 can slide on the hanging plate 4, and no matter where the sliding block 5 moves to the hanging plate 4, the height of the oxygen mask at the lower end of the gas pipe 6 remains unchanged, and the gas pipe 6 located above the sliding block 5 is in a natural bending state and will not affect the oxygen delivery, so that when the support frame 1 does not move and the oxygen mask is at the same height, it is helpful to expand the range of activities of the construction workers after wearing the oxygen mask, and it is convenient for the construction workers to wear the oxygen mask to move and switch between multiple usage scenarios such as taking tools, resting, and construction work; at the same time, since the sliding block 5 supports the longer gas pipe 6, the load of the gas pipe 6 on the construction workers wearing the oxygen mask can be reduced.

[0029] Reference Figure 1 and Figure 2 A sliding groove 12 is provided on the hanging plate 4 for slidingly cooperating with the sliding block 5. The sliding groove 12 corresponds to the sliding block 5 one by one. The setting of the sliding groove 12 can guide the sliding of the sliding block 5, and multiple sliding blocks 5 slide in different sliding grooves 12 along the hanging plate 4, so that multiple gas pipes 6 at the same end are not easily entangled.

[0030] Reference Figure 1 The end of the air pipe 6 away from the connecting pipe 3 is rotatably connected with the oxygen pipe 11. Specifically, the communication method between the air pipe 6 and the oxygen pipe 11 is the same as that in the related art. Through the cooperation of the connecting cavity and the bearing, not only can the air pipe 6 and the oxygen pipe 11 be connected, but also the oxygen pipe 11 can rotate relative to the air pipe 6. The oxygen pipe 11 is used to be connected with the oxygen mask. A flow control valve is arranged on the oxygen pipe 11, and the flow control valve is wirelessly connected to the control switch on the oxygen mask; thereby realizing the communication between the air pipe 6 and the oxygen mask, further facilitating the actions of the construction personnel, and making the air pipe 6 less likely to be entangled.

[0031] Reference Figure 2 and Figure 3An adjusting block 7 is fixedly sleeved on the gas pipe 6, and the adjusting block 7 is located below the sliding block 5. The sliding block 5 is provided with an adjusting component for adjusting the adjusting block 7 on the corresponding gas pipe 6 to slide in a direction close to or away from the sliding block 5; in order to facilitate the adjustment of the adjusting block 7 on the gas pipe 6 to slide in a direction close to or away from the sliding block 5, the adjusting component includes a connecting rope 8 and an adjusting member 9, one end of the connecting rope 8 is fixed on the corresponding adjusting block 7, and the other end is movably arranged at the sliding block 5, wherein the connecting end surface of the connecting rope 8 on the adjusting block 7 is located between the two end surfaces of the adjusting block 7 through which the gas pipe 6 passes, so as to ensure that the gas pipe 6 is not easy to fold and reduce the influence on oxygen delivery; the adjusting member 9 is arranged on the sliding block 5, and the adjusting member 9 is used to reel in or unreel the end of the connecting rope 8 away from the adjusting block 7.

[0032] Reference Figure 2 and Figure 3 In order to facilitate the winding or unwinding of the end of the connecting rope 8 away from the adjusting block 7, the adjusting member 9 includes a drum 91, a worm wheel 92 and a worm 93. The drum 91 is rotatably arranged on the bottom wall of the sliding block 5, and the rotation axis of the drum 91 is parallel to the sliding direction of the sliding block 5. The end of the connecting rope 8 away from the adjusting block 7 is wound around the corresponding drum 91, and the worm wheel 92 is coaxially fixed on the axis of the drum 91. The worm 93 is rotatably arranged at the lower end of the sliding block 5. The worm 93 is rotatably arranged in the vertical direction, and the worm 93 is meshed with the corresponding worm wheel 92. A transmission rod 13 is coaxially fixed to the lower end of the transmission rod 13, and a handle 10 is coaxially fixed to the lower end of the transmission rod 13 to facilitate the rotation of the worm 93.

[0033] When the construction workers' working area is relatively fixed and do not need to move back and forth, the worm 93 does not rotate. Through the self-locking effect between the worm 93 and the worm wheel 92, the worm wheel 92 and the reel 91 do not rotate. At this time, the connecting rope 8 is suspended by the adjusting block 7, which can enable the adjusting block 7 to support the gas pipe 6 to a certain extent, so that the gas pipe 6 will not fall down for a long time, thereby helping to reduce the load of the oxygen mask on the construction workers; when the construction workers need to move a larger range and the use scene changes, the handle 10 is turned to drive the worm 93 to rotate, the worm 93 drives the worm wheel 92 to rotate, and the worm wheel 92 drives and reels 91 to rotate synchronously, so that the reel 91 unwinds the connecting rope 8, and the adjusting block 7 moves downward under the action of gravity, so that the construction workers wearing oxygen masks can move a larger range, which is convenient for the construction workers to wear oxygen masks to move to switch between multiple use scenes such as taking tools, resting, and construction work; when the oxygen mask is located at the same height as the related technology, the range of movement of the construction workers wearing oxygen masks in this application is larger.

[0034] Reference Figure 2 The distance between the handle 10 and the ground of the construction tunnel is 1.7m-1.8m, which not only enables the construction workers to reach out and operate it, but also prevents the heads of the construction workers from hitting the handle 10.

[0035] The implementation principle of the efficient oxygen supply and ventilation system based on high-altitude tunnel construction in the embodiment of the present application is as follows: when in use, the support frame 1 can drive the oxygen tank 2 to move with the construction workers. When oxygen inhalation is needed, the construction workers wear an oxygen mask whose lower end of the gas pipe 6 is connected to the oxygen pipe 11, and turn on the corresponding solenoid valve by operating the control switch on the oxygen mask. Since the sliding block 5 can slide on the hanging plate 4, and no matter where the sliding block 5 moves to the hanging plate 4, the height of the oxygen mask at the lower end of the gas pipe 6 remains unchanged, so that when the support frame 1 does not move and the oxygen mask is at the same height as in the related art, it is helpful to expand the range of activities of the construction workers after wearing the oxygen mask, and it is convenient for the construction workers to wear the oxygen mask to move and switch between multiple usage scenarios such as taking tools, resting, and construction work; at the same time, since the sliding block 5 and the adjustment block 7 support the longer gas pipe 6, the load of the gas pipe 6 on the construction workers wearing the oxygen mask can be reduced.

[0036] When it is necessary to further adjust the moving range of the gas pipe 6, the worm 93 is driven to rotate by rotating the handle 10, and the worm 93 drives the worm wheel 92 and the reel 91 to rotate synchronously, so that the reel 91 unwinds or reels the connecting rope 8, and the adjustment block 7 moves downward or rises under the action of gravity, so that the position of the adjustment block 7 can be adjusted as needed, which is convenient for adjusting the moving range of the oxygen mask worn by the construction workers, and helps to be suitable for a variety of usage scenarios.

[0037] The present application also discloses a construction method of a high-efficiency oxygen supply ventilation system based on high-altitude tunnel construction. The construction method of a high-efficiency oxygen supply ventilation system based on high-altitude tunnel construction includes the following steps: Step 1: Slide the support frame 1 onto the slideway; Step 2: Install the required number of oxygen tanks 2 on the support frame 1 as needed: Step 3: Install the hanging plate 4 on opposite sides of the support frame 1, so that the air pipe 6 passing through the sliding block 5 on the hanging plate 4 is connected with the connecting pipe 3 near one end of the corresponding oxygen tank 2, the length of the air pipe 6 from one end of the corresponding connecting pipe 3 to the sliding block 5 is greater than the vertical distance from the connecting pipe 3 to the hanging plate 4, and the oxygen pipe 11 at the lower end of the air pipe 6 is connected to the oxygen mask.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
