[0027] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0028] like Figure 1 and Figure 2As shown, the shield system pipe changing device comprises a pipe changing frame 1, a sliding seat 2, a winding disc 3, a first hose 4 and a driving mechanism 5. The pipe changing frame 1 is arranged away from the shield device. The sliding seat 2 is slidingly arranged on the pipe changing frame 1 along the shield direction. The winding disc 3 is rotationally arranged on the sliding seat 2. The feeding end of the first hose 4 is connected with the discharging end of the first pipeline 100. The discharging end of the first hose 4 passes through the winding disc 3 and is connected with the feeding end of the second pipeline 200. The feeding end of the second pipeline 200 is connected with the discharging end of the soil bin 500 of the shield device. The driving mechanism 5 is arranged on the pipe changing frame 1. The driving end of the driving mechanism 5 is connected with the sliding seat 2. The driving mechanism 5 is used to drive the sliding seat 2 to move to the end of the pipe changing frame 1 away from the shield device.

[0029] It can be understood that, since the feeding end of the first hose 4 is connected with the discharging end of the first pipeline 100, and the discharging end of the first hose 4 is connected with the feeding end of the second pipeline 200, the feeding end of the first pipeline 100 and the feeding end of the second pipeline 200 can be connected through the first hose 4. Since the sliding seat 2 is slidingly arranged on the pipe changing frame 1 along the shield direction, and the winding disc 3 is rotationally arranged on the sliding seat 2, the discharging end of the first hose 4 passes through the winding disc 3 and is connected with the feeding end of the second pipeline 200. When the shield device is tunneling, the first hose 4 can realize the connection between the first pipeline 100 and the second pipeline 200, and at the same time, the rotation of the winding disc 3 and the sliding of the sliding seat 2 can realize the synchronous movement of the second pipeline 200 with the shield device.

[0030] Therefore, when the sliding seat 2 moves to the end of the pipe changing frame 1 close to the shield device (limit position), and the second pipeline 200 is changed and extended, since the driving end of the driving mechanism 5 is connected with the sliding seat 2, the sliding seat 2 can be reset to the end of the pipe changing frame 1 away from the shield device (initial position) under the driving of the driving mechanism 5, so that the tunneling operation can continue, and at the same time, the pipe changing device composed of the pipe changing frame 1, the sliding seat 2, the winding disc 3, the first hose 4 and the driving mechanism 5 has simple structure and occupies smaller space, so that the same side arrangement with the belt conveyor can be realized in the narrow tunnel space, and the demand for efficient construction can be met.

[0031] It should be noted that the first pipeline 100, the second pipeline 200 and the first hose 4 are used to connect the discharging end of the slurry pump 600 and the feeding end of the soil bin 500, so that the slurry treated in the slurry station 800 can be delivered to the soil bin 500 through the slurry pump 600. The specific types of the first pipeline 100, the second pipeline 200 and the first hose 4 can be set according to actual needs, which are not limited. For example, the first pipeline 100 and the second pipeline 200 are arranged along the length direction (shield direction) of the tunnel, and the first hose 4 is a hose structure which passes through the winding disc 3 away from the side of the shield device and is connected between the first pipeline 100 and the second pipeline 200.

[0032] The pipe changing frame 1 is used to carry the sliding seat 2, the winding disc 3 and the driving mechanism 5, and the specific type of the pipe changing frame 1 can be set according to actual needs, and no limitation is made thereto. For example, the pipe changing frame 1 comprises a plurality of connected cross beams, a plurality of longitudinal beams and a plurality of vertical beams. Further, the pipe changing frame 1 can further comprise a plurality of inclined beams arranged between the plurality of connected cross beams, the plurality of longitudinal beams and the plurality of vertical beams.

[0033] The sliding seat 2 is used to carry the winding disc 3, and the movement of the winding disc 3 is realized by the driving of the driving mechanism 5. The specific type of the sliding seat 2 can be set according to actual needs, and no limitation is made thereto.

[0034] The winding disc 3 is used to wind the first hose 4. When the shield device drives the second pipeline 200 to move, the second pipeline 200 drives the discharge end of the first hose 4 to move synchronously. Thus, under the dragging of the discharge end of the first hose 4, the winding disc 3 moves in the direction close to the shield device until reaching the limit position. The specific type of the winding disc 3 can be set according to actual needs, and no limitation is made thereto. For example, the winding disc 3 can be a disc structure which is rotatably arranged on the sliding seat 2 by means of a bearing.

[0035] The driving mechanism 5 is used to drive the sliding seat 2 to move to the end of the pipe changing frame 1 away from the shield device. The specific type of the driving mechanism 5 can be set according to actual needs, and no limitation is made thereto. When the shield device drives the second pipeline 200 to move, the driving mechanism 5 can also exert a small constant force on the sliding seat 2 away from the shield device to ensure the stable following of the winding disc 3.

[0036] As shown in Figure 1 and Figure 2 In some embodiments, the pipe changing device further comprises a second hose (not shown in the figure). The discharge end of the second hose is connected with the inlet end of the third pipeline 300, and the inlet end of the second hose is connected with the discharge end of the fourth pipeline 400 through the winding disc 3. The inlet end of the fourth pipeline 400 is connected with the discharge end of the soil bin 500.

[0037] It can be understood that, since the discharge end of the second hose is connected to the inlet end of the third pipeline 300, and the inlet end of the second hose is connected to the discharge end of the fourth pipeline 400, the inlet end of the third pipeline 300 and the discharge end of the fourth pipeline 400 can be connected by the second hose, and since the inlet end of the second hose bypasses the winding disc 3 and is connected to the discharge end of the fourth pipeline 400, when the shield device is tunneling, the second hose can realize the synchronous movement of the fourth pipeline 400 with the shield device by the rotation of the winding disc 3 and the sliding of the sliding seat 2 while realizing the connection between the fourth pipeline 400 and the third pipeline 300. Thus, when the sliding seat 2 moves to the end (limit position) of the pipe changing frame 1 close to the shield device, and the fourth pipeline 400 is changed and extended, the sliding seat 2 can be reset to the end (initial position) of the pipe changing frame 1 away from the shield device under the driving of the driving mechanism 5, so that the tunneling operation can continue.

[0038] It should be noted that the fourth pipeline 400, the third pipeline 300 and the second hose are used to connect the inlet end of the slurry pump 700 and the discharge end of the soil bin 500, so that the slurry in the soil bin 500 can be transported to the slurry station 800 for treatment by the slurry pump 700. The specific type of the fourth pipeline 400, the third pipeline 300 and the second hose can be set according to actual needs, which is not limited. For example, the fourth pipeline 400 and the third pipeline 300 are arranged along the length direction (shield direction) of the tunnel respectively, and the second hose is a hose structure which bypasses the winding disc 3 away from the side of the shield device and is connected between the fourth pipeline 400 and the third pipeline 300.

[0039] When the sliding seat 2 moves to the limit position, the shield device stops tunneling, and the operator adds an extension pipeline between the inlet end of the second pipeline 200 and the discharge end of the first hose 4, and adds an extension pipeline between the discharge end of the fourth pipeline 400 and the inlet end of the second hose, and then the driving mechanism 5 drives the sliding seat 2 to reset to the initial position, and the shield device continues to tunnel, thereby realizing the continuous circulation and extension of the pipeline.

[0040] As shown in Figure 1 In some embodiments, the inlet end of the first hose 4 is located above the discharge end of the first hose 4, and the inlet end of the second hose is located below the discharge end of the second hose; the pipe changing device further comprises a plurality of guide rollers 6, the guide rollers 6 are rotationally arranged on the pipe changing frame 1, and the plurality of guide rollers 6 are spaced apart along the shield direction, and the discharge end of the first hose 4 and the inlet end of the second hose bypass the winding disc 3 and are arranged on the guide rollers 6.

[0041] It can be understood that, since the feeding end of the first hose 4 is located above the discharging end of the first hose 4, and the feeding end of the second hose is located below the discharging end of the second hose, the discharging end of the first hose 4 and the feeding end of the second pipeline 200 are both located below the feeding end of the first hose 4 and the discharging end of the first pipeline 100, and the feeding end of the second hose and the discharging end of the fourth pipeline 400 are both located below the discharging end of the second hose and the feeding end of the third pipeline 300, and since the guide roller 6 is rotationally arranged on the pipe changing frame 1, and the discharging end of the first hose 4 and the feeding end of the second hose pass through the winding disc 3 and are arranged on the guide roller 6, the discharging end of the first hose 4 and the feeding end of the second pipeline 200 located below, and the feeding end of the second hose and the discharging end of the fourth pipeline 400 located below can be guided and moved by the plurality of guide rollers 6, thereby reducing the abrasion of the first hose 4, the second pipeline 200 and the fourth pipeline 400, and prolonging the service life of each component.

[0042] It should be noted that the guide roller 6 is used for supporting and guiding the discharging end of the first hose 4 and the feeding end of the second pipeline 200, and the feeding end of the second hose and the discharging end of the fourth pipeline 400, and the specific type of the guide roller 6 can be arranged according to actual needs, which is not limited, for example, the two ends of the guide roller 6 are arranged on the bottom of the pipe changing frame 1 through bearing seats, and the axial direction of the guide roller 6 is located in the width direction of the tunnel.

[0043] As shown in Figure 1 In some embodiments, the sliding seat 2 includes a first support 21 and a second support 22, the first support 21 is slidingly arranged on the pipe changing frame 1 in the shield direction, and the winding disc 3 is rotationally arranged on the first support 21, the second support 22 is slidingly arranged on the pipe changing frame 1 in the shield direction, and the second support 22 is connected with the first support 21, a limiting opening is formed between the second support 22 and the first support 21, and the discharging end of the first hose 4 and the feeding end of the second hose pass through the limiting opening respectively.

[0044] It can be understood that, since the first support 21 is slidingly arranged on the pipe changing frame 1 in the shield direction, and the winding disc 3 is rotationally arranged on the first support 21, the winding disc 3 can slide on the pipe changing frame 1 in the shield direction by the first support 21, and can also rotate under the action of the first hose 4 and the second hose, and since the second support 22 is slidingly arranged on the pipe changing frame 1 in the shield direction, and the limiting opening is formed between the second support 22 and the first support 21, and the discharging end of the first hose 4 and the feeding end of the second hose pass through the limiting opening respectively, the second support 22 can ensure that the first support 21 stably slides on the pipe changing frame 1, and can also limit the first hose 4 and the second hose, thereby ensuring the stable following of the second pipeline 200, the fourth pipeline 400, the winding disc 3 and the like during the tunneling process of the shield device.

[0045] It should be noted that the first bracket 21 and the second bracket 22 are used to form the structure of the frame of the slide 2 to support the winding disk 3 and limit the first hose 4 and the second hose. The specific types of the first bracket 21 and the second bracket 22 can be set according to actual needs and are not limited to this. For example, the first bracket 21 and the second bracket 22 can both be beam structures arranged along the width direction of the tunnel, and the first bracket 21 and the second bracket 22 are connected to form a frame that is close to the shape of a "mouth".

[0046] like Figure 1 As shown, in some embodiments, the pipe changing device further includes: a plurality of rollers 7, which are rotatably arranged on the pipe changing rack 1, and the plurality of rollers 7 are spaced apart along the shield direction, and the discharge end of the first pipeline 100 and the feed end of the third pipeline 300 are respectively arranged on the rollers 7 and connected to the pipe changing rack 1.

At the same time, the rotation of multiple rollers 7 facilitates the disassembly, assembly and maintenance of the discharge end of the first pipeline 100 and the feed end of the third pipeline 300, thereby making the use of the pipe changing device more flexible and convenient.

[0048] It should be noted that the roller 7 is used to support the discharge end of the first pipeline 100 and the feed end of the third pipeline 300. The specific type of the roller 7 can be set according to actual needs and is not limited to this. For example, the two ends of the roller 7 are respectively set on the top of the pipe changing rack 1 through bearing seats, and the axial direction of the roller 7 is located in the width direction of the tunnel.

[0049] Among them, while the roller 7 supports the discharge end of the first pipeline 100 and the feed end of the third pipeline 300, the discharge end of the first pipeline 100 and the feed end of the third pipeline 300 can also be fixed on the pipe changing rack 1 by using fixing parts such as fixing plates and bolts.

[0051] It can be understood that, since the base of the winch 51 is arranged on the pipe changing rack 1, and the reversing wheel 52 is rotationally arranged on the sliding seat 2, the winding rope of the winch 51 is arranged on the base of the winch 51 and passes through the reversing wheel 52, so that when the drum of the winch 51 winds the winding rope, the sliding seat 2 can be pulled by the cooperation of the reversing wheel 52, so that the sliding seat 2 and the winding disc 3 on the sliding seat 2 can move away from the shield device until reaching the initial position.
