Description

Technical Field

[0002] At present, the three main methods used in the construction of dark excavation tunnel projects are drilling and blasting, TBM, and shield. The drilling and blasting method is widely used because of its long history, high maturity, strong flexibility, adaptability, and relatively low cost. In the case of complex geological structure, weak and uneven surrounding rock, the drilling and blasting method has higher flexibility and adaptability. The efficiency and safety of the drilling and blasting method need to be further improved to improve the construction efficiency under complex geological conditions. Existing technologies generally use protective airbags for surrounding rock support, using the deformation of the protective airbags to absorb the energy brought by rock bursts and falling rocks. The protective airbags are designed for constant resistance (the internal air pressure is kept constant). When the force brought by the surrounding rock reaches a certain value, the support will reach a balance state, reach a new balance, and form a new effective support.

[0003] At present, for the existing airbag protection, when supporting the supporting surface, it can only be moved as a whole over a large area through an externally installed displacement mechanism (such as a walking structure), and the existing airbag protection structure can only be moved as a whole through an externally installed displacement mechanism, and it needs to be completely separated from the original support position before it can be moved as a whole.

That is, in this embodiment, by setting a displacement mechanism 2 at the bottom of the frame 1, the displacement mechanism 2 drives the frame 1 to move as a whole, and after the airbag protection mechanism 4 is used to inflate the support position of the support space, the displacement mechanism 2 can drive the frame 1 to continue to move, and at the same time, a group of airbag protection mechanisms 4 at the supported stable position can be degassed and separated, and the other airbag protection mechanisms 4 do not change the support position on the original basis, and then the first traction mechanism 3 and the second traction mechanism 5 are used to traction and drive a group of airbag protection mechanisms 4 at the supported stable position to adjust the position on the frame 1, so as to adjust the protection position of the airbag protection mechanism 4 on the frame 1, so that the airbag protection mechanism 4 on the frame 1 can be adjusted continuously in the direction of excavation, and the airbag protection mechanism 4 on the frame 1 does not need to be completely detached, so as to achieve a constant support force for the position to be supported in the support space. That is, it effectively solves the disadvantage of the prior art that it is necessary to completely detach from the original support position before the overall movement can be carried out.

[0065] Reference Figure 1 and Figure 2Specifically, the frame 1 is in an inverted U shape as a whole, and the frame 1 includes: two first rails 11, a plurality of second rails 12 and a third rail 13. The first rail 11 is in an inverted U shape, and the two first rails 11 are symmetrically arranged. The plurality of second rails 12 are arranged between the two first rails 11, and the two ends of the plurality of second rails 12 are respectively connected to the two first rails 11. The third rail 13 is in a C shape, and the third rail 13 is arranged at one side of the bottom of the two first rails 11, and the two ends of the third rail 13 are respectively connected to the two first rails 11, and the setting direction of the third rail 13 is parallel to the second rail 12. That is, in this embodiment, the two first rails 11 are horizontally connected by a plurality of second rails 12, and then the third rail 13 is used to connect the two first rails 11 as a whole at one side of the bottom of the two first rails 11, so as to realize that the first rail 11, the second rail 12 and the third rail 13 on the frame 1 form a complete channel, so that the airbag protection mechanism 4 can change the support position along with the channel in accordance with the excavation direction. In this embodiment, the first traction mechanism 3 is arranged at the first track 11 away from the third track 13, and the first traction mechanism 3 is used to traction and drive the airbag protection mechanism 4 to slide in a U shape on the first track 11. Preferably, the first traction mechanism 3 can be a winch. In addition, in this embodiment, the second traction mechanism 5 is arranged at the third track 13, and the second traction mechanism 5 is used to drive the airbag protection mechanism 4 to transfer from one first track 11 to another first track 11 through the third track 13, so as to enable the airbag protection mechanism 4 to change the support position between the two first tracks 11 and the third track 13. Specifically, the second traction mechanism 5 includes: a traction machine 51 and a traction crawler 52. That is, the second traction mechanism 5 drives the traction crawler 52 through the traction machine 51 to adjust the support position of the airbag protection mechanism 4 on the displacement third track 13. It should be noted that the implementation means of the first traction mechanism 3 and the second traction mechanism 5 can be such as a winch, a traction crawler 52, etc., or can be implemented by a linear motion method, such as a screw reciprocating mechanism, which will not be described in detail here. In addition, the displacement mechanism 2 may be track-type, wheel-type or track-type.

[0066] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 and Fig. 9In this embodiment, in order to facilitate understanding of how to adjust the supporting position of the airbag protection mechanism 4 on two first rails 11 through a plurality of second rails 12, the following description is given here. Specifically, a plurality of second rails 12 are provided with a traction groove (not shown in the figure) at one end, the traction groove is located at one first rail 11, and the traction groove is close to the first traction mechanism 3. The airbag protection stand also includes: a plurality of propulsion groups, the plurality of propulsion groups are respectively provided at one end of the plurality of second rails 12, the propulsion groups are located at the traction groove of the second rail 12, and the propulsion groups are used to drive the airbag protection mechanism 4 from one first rail 11 to another first rail 11 through the second rail 12 when the displacement mechanism 2 drives the frame 1 to move as a whole. Here, in order to facilitate description of how the propulsion group moves the airbag protection mechanism 4 located on the second rail 12 from one first rail 11 to another rail, a propulsion group on a second rail 12 is used as an example. Specifically, one propulsion group includes: a propulsion member 122 and a propulsion block 123. The pusher 122 is arranged in the traction groove, and one end of the pusher 122 is connected to the second track 12 in the traction groove. The pusher block 123 is arranged at the second track 12, and the pusher block 123 is connected to the other end of the pusher 122, and the pusher block 123 is slidably located in one of the first tracks 11, and the pusher block 123 is used to push the airbag protection mechanism 4 located at the first track 11 into the second track 12 until it moves to another first track 11 through the second track 12. That is, in this embodiment, the pusher 122 drives the pusher block 123 to push the airbag protection mechanism 4 located at the first track 11 into the second track 12 until it moves to another first track 11 through the second track 12, so as to enable the airbag protection mechanism 4 to adjust the support position on the first track 11 and the second track 12. Preferably, the pusher rod can be a pusher, such as any one of an electric pusher, a hydraulic pusher or a pneumatic pusher. That is, in this embodiment, the first traction mechanism 3 sets up a winch at one of the first rails 11, and the winch drives the airbag protection mechanism 4 on the first rail 11 to be pulled as a whole to the second rail 12 close to the traction groove, and then uses the propulsion group at the traction groove to propel it into the second rail 12 until it reaches another first rail 11. It should be noted that the propulsion speed of the propulsion rod is consistent with the movement speed of the frame 1 driven by the displacement mechanism 2, so that the support position of the airbag protection mechanism 4 can remain unchanged when the displacement mechanism 2 drives the frame 1 to move. That is, the propulsion direction of the propulsion rod is opposite to the propulsion direction of the displacement mechanism 2.

[0067] Reference Figure 1 , Figure 2 and Figure 6In this embodiment, the plurality of airbag protection mechanisms 4 are adjusted and supported on the first track 11, the second track 12 and the third track 13 on the frame 1. For the convenience of describing the airbag protection mechanism 4, one airbag protection mechanism 4 is used as an example. Specifically, one airbag protection mechanism 4 includes: a plurality of protective airbags 41, a plurality of bottom plates 42, a plurality of connecting steel cables 43 and a plurality of slide plates 45. The protective airbags 41 are made of elastic material, and a trachea connector 44 is provided on each of the plurality of protective airbags 41. The protective airbags 41 are used for inflating and supporting through the trachea connector 44. The plurality of bottom plates 42 are respectively provided at one end of the plurality of protective airbags 41, and the bottom plates 42 are used for supporting the protective airbags 41. The plurality of slide plates 45 are provided at the bottom of the plurality of bottom plates 42, and the slide plates 45 are used for driving the bottom plates 42 and the protective airbags 41 to slide in the first track 11, the second track 12 and the third track 13. The plurality of connecting steel cables 43 are respectively arranged on the protective airbags 41, and the plurality of connecting steel cables 43 are used to connect the plurality of protective airbags 41 in a row and connect them end to end. That is, in this embodiment, by arranging the protective airbags 41 on the bottom plate 42, the protective airbags 41 are inflated and supported through the trachea connector 44, and the connecting steel cables 43 are used to connect the plurality of airbag protection mechanisms 4 in series as a whole, so as to effectively enhance the support effect of the single airbag protection mechanism 4, and the sliding plate 45 is used to drive the protective airbags 41 and the bottom plate 42 to slide in the first track 11, the second track 12 and the third track 13 respectively. Preferably, the protective airbags 41 are made of rubber, and the protective airbags 41 support the support space after being inflated through the trachea connector 44. It should be noted that, in this embodiment, the bottom plates 42 on the plurality of protective airbags 41 are in end-to-end contact on the second track 12 and the two first tracks 11, that is, the plurality of protective airbags 41 on each airbag protection mechanism 4 are all moved in series end-to-end on the first track 11, the second track 12 and the third track 13 through the connecting steel cable 43. The support positions of the support space of the plurality of airbag protection mechanisms 4 are respectively inflated, deflated and separated. In addition, the spacing between the plurality of airbag protection mechanisms 4 is consistent with the spacing between the plurality of second tracks 12, so as to facilitate the adjustment and fixation of the support position when the propulsion group is moved from the first track 11 to the second track 12.

[0068] In this embodiment, when the airbag protection mechanism 4 is in use, the air pipe joint 44 can be used to inflate the inside of the protection airbag 41, so that the protection airbag 41 can support the supporting position of the supporting space as a whole. When the protection airbag 41 is used to bear the pressure of the support position of the supporting space by crushed stone impact, the multiple protection airbags 41 in the airbag protection mechanism 4 are interconnected to share the pressure, and the multiple airbag protection mechanisms 4 can also bear the pressure sharing. Correspondingly, the multiple protection airbags 41 in the airbag protection mechanism 4 and / or the multiple airbag protection mechanisms 4 can also relieve and replenish pressure mutually.

[0069] In this embodiment, in order to facilitate the airbag protection structure to move more smoothly on the second track 12, guide grooves 421 are provided on both sides of the bottom plate 42, and two first guide rods 121 are also provided on the second track 12. The two first guide rods 121 are symmetrically arranged, and the bottom plate 42 is slidably connected to the two first guide rods 121 through the guide grooves 421 on both sides. Accordingly, in a preferred embodiment, corresponding first guide rods 121 can also be provided on the first track 11 and the third track 13, so that the guide grooves 421 on the bottom plate 42 are guided on the first track 11 and the third track 13 through the first guide rods 121.

[0070] Reference Figure 7 In this embodiment, in order to make the second traction mechanism 5 pull the airbag protection mechanism 4 from one first track 11 to another first track 11 via the third track 13 more smoothly, a C-shaped groove structure (not shown in the figure) is provided on the third track 13, and the airbag protection mechanism 4 is slidably connected in the C-shaped groove structure, and the airbag protection mechanism 4 is transmission-connected with the traction track 52 of the second traction mechanism 5, so that the second traction mechanism 5 can pull the airbag protection mechanism 4 from one first track 11 to another first track 11 via the third track 13 through the traction track 52. Here, in order to prevent the airbag protection mechanism 4 from running out of the third track 13, two first limiting rods 131 and two second limiting rods 132 are further provided on the third track 13. The two first limiting rods 131 are symmetrically arranged on the C-shaped groove structure of the third track 13, and the first limiting rods 131 are used to cooperate with the C-shaped groove structure to clamp the bottom plate 42 of the airbag protection mechanism 4 in the C-shaped groove and slide. The two second limiting rods 132 are symmetrically arranged inside the C-shaped groove structure of the third track 13 , and the two second limiting rods 132 are used to guide the airbag protection mechanism 4 as a whole inside the C-shaped groove structure of the third track 13 .

[0071] Reference Figures 9 and 10In a second aspect of this embodiment, the present invention further provides a method for using a mobile and recyclable airbag protection stand, wherein the method adopts a mobile and recyclable airbag protection stand in the first aspect, and the method comprises:

[0072] Obtain the position to be supported of the support space;

[0073] The airbag protection stand is preliminarily moved to the waiting support position of the support space by the displacement mechanism 2, and the airbag protection mechanism 4 on the airbag protection stand is used to inflate and support the waiting support position of the support space, and determine the first initial position of the airbag protection stand as a whole;

[0074] After supporting for a period of time, the displacement mechanism 2 is used to drive the frame 1 to move along the excavation direction A by a unit position (preferably, one unit position can be the length of the bottom plate 42 under the protective airbag 41, so as to facilitate the position change of the airbag protection mechanism 4), and at the same time, the propulsion group is used on the multiple second tracks 12 to reversely push the airbag protection mechanism 4 on the first track 11 to the second track 12, that is, when the displacement mechanism 2 drives the frame 1 to move, the propulsion group synchronously pushes the multiple airbag protection mechanisms 4 in the reverse direction to ensure that the support positions of the multiple airbag protection mechanisms 4 for the support space remain unchanged. At this time, as the frame 1 changes from the first initial position, the multiple airbag protection mechanisms The supporting position of the 4 pairs of supporting spaces remains unchanged, the airbag protection mechanism 4 originally on a first track 11 is changed to one end of the plurality of second tracks 12, and the airbag protection mechanism 4 on the other end of the second track 12 is changed to another first track 11. At this time, it can be determined whether the supporting position of the airbag protection mechanism 4 on another first track 11 is stable. After stabilization, the airbag protection mechanism 4 on another first track 11 can be deflated and separated, and then sequentially pulled to a first track 11 through the second traction mechanism 5 and the first traction mechanism 3, and then controlled to inflate using the air pipe joint 44, so that the protective airbag 41 inflates and supports the position to be supported in the supporting space. That is, in this embodiment, the propulsion direction B of the propulsion group is opposite to the excavation direction A.

[0075] like Fig.10 In this embodiment, in order to facilitate understanding of how to adjust the protection position of the airbag protection mechanism 4 on the airbag protection stand, the following description is given here. The method for adjusting the protection position of the airbag protection mechanism 4 on the airbag protection stand includes:

[0076] When the displacement mechanism 2 drives the frame 1 to move as a whole, the airbag protection mechanism 4 on a first track 11 is synchronously transformed to one end of a plurality of second tracks 12 by a plurality of propulsion groups at the same time;

[0077] The airbag protection mechanism 4 on the other end of the second track 12 is allowed to move to the other first track 11 through the bottom plate 42;

[0078] Then, the airbag protection mechanism 4 on the other first track 11 is pulled onto the third track 13 by the second pulling mechanism 5 on the third track 13, until the airbag protection mechanism 4 is moved to the lower part of the first track 11 by the third track 13;

[0079] Then, a first track 11 is used to lift the original airbag protection mechanism 4 at the third track 13 to the first track 11 through the winch in the first traction mechanism 3, and the operation is repeated until the airbag protection mechanism 4 changes the support position of the support space along the tunnel excavation direction A. That is, in this embodiment, the overall position of the airbag protection mechanism 4 on the frame 1 is adjusted by moving the airbag protection mechanism 4 on the first track 11 through the second track 12 and the third track 13, so as to adjust the support position of each airbag protection mechanism 4 on the frame 1 accordingly, and then the support position of the support space can be adjusted. In this embodiment, the position adjustment of the airbag protection mechanism 4 can be controlled by wireless or wired means, so that communication control can be achieved through communication terminals such as mobile phones and computers. That is, the first traction mechanism 3 and the second traction mechanism 5, the displacement mechanism 2 and the inflation and deflation method of the airbag protection mechanism 4 can all be controlled by electrical connection. It will not be described in detail here. In this embodiment, the position of the protective airbag 41 cannot be adjusted when it is inflated (i.e., when it is supporting the position to be supported in the support space). The first traction mechanism 3, the second traction mechanism 5 and the propulsion group can be used to replace and adjust the position on the frame 1 only after the protective airbag 41 is deflated and separated from the position to be supported in the support space.

[0080] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
