It mainly provides fresh air flow and promotes air circulation for the personnel working at the tunneling face, removes dust and harmful gases, and ensures the safety of the tunneling face. With the development of rapid tunneling technology and equipment, the tunneling speed has been greatly improved. However, the traditional method of manually connecting the air duct is not only labor-intensive and inefficient, but also requires the operators to work at height when the tunnel height is too high, which poses a safety hazard. If the connection is not timely, it will also cause dust and harmful gases to accumulate at the head of the tunnel, bringing safety hazards. It can no longer adapt to the current production process of rapid tunneling technology.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. In the description of the present invention, it should be understood that, unless otherwise specified, the meaning of "multiple" is two or more.

[0047] See also Figure 1 A novel self-extending device for a wind duct 3 on an excavation working face according to a specific embodiment of the present invention comprises a mobile platform 1, a wind duct storage container 2, a wind duct 3, a traction assembly 4 and a hanger assembly 5, wherein the mobile platform 1 is suitable for being moved to a set position and fixed in place, the wind duct 3 is placed in the wind duct storage container 2, the wind duct storage container 2 is arranged on the mobile platform 1, and can move synchronously with the mobile platform 1, the hanger assembly 5 is arranged horizontally along the excavation direction, and the hanger assembly 5 is connected to the mobile platform 1 via the traction assembly 4, the wind duct 3 is connected to the traction assembly 4 via the hook assembly 6, and the wind duct 3 is pulled by the traction assembly 4 to move along the set path, thereby realizing the extension of the wind duct 3 along the excavation direction.

[0048] Specifically, the mobile platform 1 is also provided with a lifting platform 11, which has a horizontal and vertical movement stroke, and the wind tube storage 2 is arranged on the lifting platform 11 and can move synchronously with the lifting platform 11. In addition, the mobile platform 1 is also provided with a guide assembly 12, a rope winding wheel 13 and a rope reel 14, one end of the traction assembly 4 is wound around the rope reel 14, and the other end is wound around the rope winding wheel 13, and after the traction assembly 4 is led out through the rope reel 13, it passes through the guide assembly 12 and the hanger assembly 5 in sequence and is finally wound around the rope reel 14.

[0049] See also Figures 2 to 3 The traction assembly 4 includes a driving device 41 and a steel wire rope 42 arranged on the rope reel 14, wherein the steel wire rope 42 can connect the rope reel 14 and the rope winding wheel 13, and the driving device 41 is connected to the rope reel 14 in a transmission manner to drive the rope reel 14 to rotate, and when the rope reel 14 is driven to rotate, the steel wire rope 42 can be continuously pulled to move between the rope reel 14 and the rope winding wheel 13, so as to achieve the traction of the wind tube 3 hung on the steel wire rope 42. It should be noted that the driving device 41 can adopt devices such as explosion-proof motors or drive motors, and the driving device 41 can be driven forward or reversely. When the driving device 41 is driven forward, the steel wire rope 42 is tensioned by the traction force, and the wind tube 3 is pulled forward along the set path; when the driving device 41 is driven in the reverse direction, the steel wire rope 42 is relaxed, and at this time, it is necessary to manually lead the steel wire rope 42 out of the hanger assembly 5.

[0050] Specifically, the guide assembly 12 includes a first guide wheel 121 and a first check mechanism 71. The first check mechanism 71 can receive the wire rope 42 led out through the rope winding wheel 13, and the first guide wheel 121 can receive the wire rope 42 led out through the first check mechanism, so that the wire rope 42 can pass through the first check mechanism 71 and the first guide wheel 121 in sequence and then be introduced into the hanger assembly 5.

[0051] See also Figures 4 to 5 The hanger assembly 5 includes a hanger 52, an anchor cable 53, a second guide wheel 51 and a second check mechanism 72, wherein the anchor cable 53 is connected to the hanger 52 via a fixing member 54, the second guide wheel 51 is arranged on the hanger 52, a bearing 55 is provided between the second guide wheel 51 and the hanger 52, and the second guide wheel 51 is suitable for receiving the steel wire rope 42 led out by the first guide wheel 121, and the second check mechanism 72 is arranged in the introduction direction of the second guide wheel 51 to limit the retreat of the led-out steel wire rope 42.

[0052] See also Figures 6 to 8 The first check mechanism 71 and the second check mechanism 72 both include a torsion spring 73, a mounting frame 74 and a plurality of shift blocks 75.

The wire rope 42 is arranged between the plurality of shift blocks 75. The shift blocks 75 arranged in the first check mechanism 71 and the second check mechanism 72 are all inclined toward the corresponding first guide wheel 121 or second guide wheel 51, and the contact surface between each shift block 75 and the wire rope 42 is cut obliquely to form a bevel surface, which can be a rough plane, so as to increase the friction between the bevel surface and the wire rope 42 to ensure that the wire rope 42 does not retreat. Moreover, the setting of the torsion spring 73 enables the multiple relatively arranged shift blocks 75 to press against the wire rope 42. When the wire rope 42 has a tendency to retreat, the multiple shift blocks 75 have a tendency to move relatively. However, since the multiple shift blocks 75 are arranged at an angle, when a tendency to move relatively occurs, the multiple shift blocks 75 will generate pressure on the wire rope 42, thereby limiting the movement of the wire rope 42.

[0053] See also Fig. 9The hook assembly 6 includes a hook 61 and a locking screw 62. The hook 61 is in an S-shaped structure. The hook 61 of the S-shaped structure defines two accommodating chambers 63. The wire rope 42 is inserted into one of the accommodating chambers 63, and the hanging ring of the wind tube 3 is hung in the other accommodating chamber 63. A limiting plate 64 is provided at the opening of one of the accommodating chambers 63 through which the wire rope 42 is inserted. The limiting plate 64 is arranged so that the wire rope 42 will not slide out easily after being placed in the accommodating chamber 63. The locking screw 62 is suitable for being embedded in the accommodating chamber 63, and an abutting portion 621 is provided at the embedded end of the locking screw 62. The abutting portion 621 is made of a plastic material. The abutting portion 621 and the wire rope 42 can be fixed to the wire rope 42 by abutting against each other, so as to prevent the wind tube 3 from sliding after being fixed on the wire rope 42.

[0054] See also Fig.10 , a method for operating a novel self-extending device for a tunneling working face wind tube 3 according to a specific embodiment of the present invention is applied to the novel self-extending device for a tunneling working face wind tube 3 according to any of the above embodiments, and the method comprises the following steps:

[0055] The mobile platform 1 moves to a set position and is fixed;

[0056] Fix the hanger assembly 5 and the air cylinder reservoir 2 at the set position;

[0057] The mobile platform 1 and the hanger assembly 5 are connected in series through the traction assembly 4;

[0058] Hang the air cylinder 3 in the air cylinder storage 2 on the traction assembly 4;

[0059] The wind tube 3 is pulled to a set position by the pulling assembly 4.

[0060] Specifically, after the mobile platform 1 is moved to the set position and fixed, the hanger 52 is first fixedly connected to the anchor cable 53 by the locking screw 62, so as to fix the hanger 52. Then, after the rope reel 13 equipped with the wire rope 42 is fixed to the set position of the mobile platform 1, one end of the wire rope 42 on the rope reel 13 is taken out and led out from the first check mechanism 71, the first guide wheel 121, the second check mechanism 72, and the second guide wheel 51 respectively, and the hanger 52 also has the function of anti-slip limit, and finally the wire rope 42 led out from the second guide wheel 51 is fixed to the rope reel 14 on the mobile platform 1. After the fixing is completed, the position of the lifting platform is adjusted so that the wind tube 3 in the wind tube storage 2 set on the lifting platform can be smoothly hung on the wire rope 42 through the hook assembly 6 and locked after being taken out (the subsequent wind tubes 3 are fixed to the wire rope 42 in the same way).

[0061] More specifically, after the wind cylinder 3 is fixed, the driving device 41 is used to drive the rope winding wheel 14 to rotate. The cooperation between the driving device 41 and the rope winding wheel 14 can achieve the purpose of the winch. At the same time, the wind cylinder 3 is driven forward while pulling the wire rope 42. When the wind cylinder 3 moves to the position of the hanger 52, the driving device 41 is turned off, and then the hanger 52 is manually fixed to the new anchor rod.

[0062] Furthermore, when the wind tube 3 in the wind tube storage 2 is used up, the driving device 41 is turned off, and then a new wind tube 3 is placed in the wind tube storage 2, the position of the lifting platform is adjusted, and then the connection position of the wind tube 3 is disassembled, and then the two ends of the wind tube 3 in the wind tube storage 2 are connected, and the driving device 41 is turned on again to continue to drive the wind tube 3 forward. When the wire rope 42 on the rope wheel 13 is used up, the driving device 41 is driven to reverse, so as to release the wire rope 42 from the rope wheel 14, and fix it on the sling or anchor rod on the spot, and then drive the mobile platform 1 to move to a suitable position, and finally repeat the above steps to cycle the operation.
