[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Please refer to Figures 1 to 4 , Figure 1 A working state diagram of a segment unloading vehicle for a shield machine provided in a specific embodiment of the present invention; Figure 2 This is a front view of a segment unloading vehicle for a shield machine provided by the present invention; Figure 3 for Figure 2 Side view of Figure 4 for Figure 2 Structural diagram of the telescopic arm on the middle left.

[0045] The embodiment of the present invention discloses a segment unloading vehicle for a shield machine, comprising a movable bracket 1, a lifting bracket 2 and a supporting bracket 3, and is also equipped with a rear matching trolley 02 and a segment 01 conveying vehicle.

[0046] Among them, the rear matching trolley 02 is door-shaped, and the segment unloading vehicle is arranged in the rear matching trolley 02. The segment 01 conveying vehicle is placed on the box culvert 04 and is used to carry the segment 01.

[0047] The two sides of the mobile bracket 1 are respectively fixedly connected to the two opposite sides of the rear matching trolley 02, and the mobile bracket 1 is arranged outside the segment transport vehicle 03, so that the mobile bracket 1 and the matching trolley 02 can move synchronously, so that the rear matching trolley 02 drives the mobile bracket 1 to move along the box culvert 04 relative to the segment transport vehicle 03. In this specific embodiment, the mobile bracket 1 is also gate-shaped.

[0048] The lifting bracket 2 is arranged on the top of the movable bracket 1 , and the lifting bracket 2 can be lifted and lowered relative to the segment transport vehicle 03 in a direction perpendicular to the box culvert 04 , so as to facilitate approaching or moving away from the segment 01 .

[0049] The supporting bracket 3 is arranged on the top of the lifting bracket 2 and has two relatively retractable telescopic arms 31. The two telescopic arms 31 are retracted and extended in parallel to the top surface of the box culvert 04. When the supporting bracket 3 is lifted and lowered synchronously with the lifting bracket 2 until it is close to the segment 01 carried by the segment transport vehicle 03, the two telescopic arms 31 move closer to each other so that the distance between the two telescopic arms 31 is smaller than the width of the segment 01, so that the two telescopic arms 31 support the segment 01 and the telescopic arms 31 drive the segment 01 to rise and fall with the lifting bracket 2 until the segment 01 is separated from the segment transport vehicle 03, thereby realizing the unloading of the segment 01.

[0050] When in use, the lifting bracket 2 first rises in a direction perpendicular to the box culvert 04, so that the supporting bracket 3 is close to the bottom of the segment transport vehicle 03; then the two telescopic arms 31 of the supporting bracket 3 are brought close to each other until the segment 01 is lifted; then the lifting bracket 2 continues to rise in a direction perpendicular to the box culvert 04, and the supporting bracket 3 drives the segment 01 to separate from the segment transport vehicle 03; finally, the mobile bracket 1 is started again, and the mobile bracket 1 is then equipped with a trolley 02 to move along the box culvert 04 relative to the segment transport vehicle 03, so that the segment 01 is further away from the segment transport vehicle 03, thereby realizing the unloading of the segment 01, without the need to unload the segment 01 by hoisting, which is convenient for batch unloading of the segment 01, and can avoid affecting the transportation of other materials to the shield machine, which is conducive to shortening the unloading time of the segment 01 and improving the unloading efficiency. Therefore, the segment unloading vehicle for the shield machine provided by the present invention can effectively improve the construction efficiency.

[0051] In this specific embodiment, the mobile bracket 1 includes a left support frame 11 and a right support frame 12 that are arranged opposite to each other. Two left support frames 11 are arranged on the left side of the mobile bracket 1, and two right support frames 12 are symmetrically arranged on the right side thereof. The heights of the left support frames 11 and the right support frames 12 are equal. The mobile bracket 1 also includes a left connecting rod fixedly connected between the two left support frames 11 and a right connecting rod fixedly connected between the two right support frames 12.

[0052] The bottom of the left support frame 11 and the right support frame 12 are both provided with moving rollers 13, and the moving rollers 13 respectively drive the left support frame 11 and the right support frame 12 to move along the box culvert 04. The moving rollers 13 are respectively hinged to the bottom of the left support frame 11 and the right support frame 12 through roller pins, and can be rubber rollers, but are not limited thereto.

[0053] The outer sides of the left support frame 11 and the right support frame 12 are respectively provided with guide rollers 14, which cooperate with the guide rods provided on the two opposite sides of the rear supporting trolley 02. The guide rods guide the guide rollers 14 to move in a straight line, and prevent the mobile bracket 1 from tipping over. Specifically, the outer side of the left support frame 11 is provided with a left guide seat, and the outer side of the left support frame 11 is specifically the side of the left support frame 11 away from the right support frame 12. The guide roller 14 is hinged to the end of the left guide seat close to the rear supporting trolley 02 through a pin shaft. Similarly, the outer side of the right support frame 12 is symmetrically provided with a right guide seat, and the guide roller 14 is also hinged to the end of the right guide seat close to the rear supporting trolley 02 through a pin shaft. The left guide seat and the right guide seat are both L-shaped and vertically welded to the outer side of the mobile bracket 1.

[0054] In this specific embodiment, the telescopic arm 31 includes a left telescopic arm 311 and a right telescopic arm 312 which are respectively arranged on the top of the left support frame 11 and the right support frame 12. When the left telescopic arm 311 and the right telescopic arm 312 are brought close to each other by synchronously extending, the left telescopic arm 311 and the right telescopic arm 312 can support the pipe segment 01; when the left telescopic arm 311 and the right telescopic arm 312 are moved away from each other by synchronously contracting, the left telescopic arm 311 and the right telescopic arm 312 can detach from the pipe segment 01, so that the pipe segment 01 can be unloaded.

[0055] In this specific embodiment, the lifting bracket 2 is preferably hydraulically driven, and of course it can also be electrically driven or pneumatically driven, which is not specifically limited here. Correspondingly, the present invention also includes a left lifting drive 21, a left lifting guide sleeve 22, a right lifting drive 23 and a right lifting guide sleeve 24, wherein the left lifting drive 21 is arranged in the left support frame 11, and is used to drive the left telescopic arm 311 to rise and fall in a direction perpendicular to the box culvert 04. The right lifting drive 23 is arranged in the right support frame 12, and is used to drive the right telescopic arm 312 to rise and fall. The left lifting drive 21 and the right lifting drive 23 are both hydraulic cylinders, and the free ends of the two are respectively connected to the left telescopic arm 311 and the right telescopic arm 312.

[0056] The left lifting guide sleeve 22 is nested in the top of the left support frame 11, and the left lifting guide sleeve 22 is fixedly connected to the left telescopic arm 311. When the left telescopic arm 311 is extended and retracted, the left lifting drive member 21 drives the left lifting guide sleeve 22 to rise and fall along the inner wall of the left support frame 11, thereby guiding the left telescopic arm 311 to rise and fall, preventing the left lifting drive member 21 from swinging during the lifting process, which is beneficial to prolonging the service life of the left lifting drive member 21 and improving the stability of the left telescopic arm 311. Similarly, the right lifting guide sleeve 24 is nested in the top of the right support frame 12 and is fixedly connected to the right telescopic arm 312, so that the right lifting guide sleeve 24 guides the right telescopic arm 312 to rise and fall, thereby prolonging the service life of the right lifting drive member 23 and improving the stability of the right telescopic arm 312 at the same time.

[0057] Preferably, the telescopic arm 31 is also hydraulically driven. Accordingly, the supporting bracket includes a left telescopic drive member 32 and a right telescopic drive member. The left telescopic drive member 32 is arranged in the left telescopic arm 311, perpendicular to the left lifting drive member 21, and is used to drive the left telescopic arm 311 to extend and retract. Similarly, the right telescopic drive member is arranged in the right telescopic arm 312, perpendicular to the right lifting drive member 23, and is used to drive the right telescopic arm 312 to extend and retract. Both the left telescopic drive member 32 and the right telescopic drive member are hydraulic cylinders, which are not specifically limited here.

[0058] Specifically, the left telescopic arm 311 includes a left fixed sleeve fixed to the top of the left support frame 11, and also includes a left sliding sleeve nested in one end of the left fixed sleeve and sliding relative to the left fixed sleeve. The cylinder of the left telescopic drive member 32 is fixed in the left fixed sleeve, and the piston rod of the left telescopic drive member 32 is fixedly connected to the left sliding sleeve. When the left telescopic drive member 32 is extended or retracted, the left sliding sleeve slides along the axial direction of the left fixed sleeve, thereby achieving extension and retraction. Similarly, the structure of the right telescopic arm 312 is the same as that of the left telescopic arm 311, and will not be repeated here.

[0059] In order to stably support the pipe segment 01, the free ends of the left telescopic arm 311 and the right telescopic arm 312 are both provided with support surfaces, which coincide with the bottom of the pipe segment 01 to support the pipe segment 01. The support surface can be a plane or a curved surface, which is set according to the actual situation.

[0060] To achieve automation, the present invention further includes a height detection member and a controller, wherein the height detection member is respectively provided on the left support frame 11 and the right support frame 12, and is respectively used to detect the lifting height of the left support frame 11 and the right support frame 12. The height detection member may be a height detection sensor, but is not limited thereto.

[0061] The controller is connected to the left lifting drive 21, the right lifting drive 23, the left telescopic drive 32, the right telescopic drive and the height detection part respectively. The controller controls the left lifting drive 21 and the right lifting drive 23 to rise synchronously according to the signal sent by the height detection part, so that the left support frame 11 and the right support frame 12 rise synchronously until the rising height of the two reaches the first preset height, and the first preset height here specifically refers to the height when the left support frame 11 or the right support frame 12 moves from the initial position to the bottom of the segment 01 carried by the segment transport vehicle 03.

[0062] Then, when the left support frame 11 and the right support frame 12 rise synchronously to the first preset height, the height detection component sends a signal to the controller again, and the controller controls the left telescopic drive component 32 and the right telescopic drive component to extend synchronously, thereby ensuring that the left telescopic arm 311 and the right telescopic arm 312 are extended synchronously until the distance between the two is less than the width of the pipe segment 01, thereby supporting the pipe segment 01.

[0063] Based on the above content, the present invention can realize automatic rising and automatic supporting of the pipe segment 01, with a high degree of automation. At the same time, it can effectively prevent the side plate of the pipe segment 01 caused by the different lifting heights of the left support frame 11 and the right support frame 12, and the construction efficiency is further improved.

[0064] Furthermore, the present invention also includes a pressure detection member, which is respectively arranged at the top of the left telescopic arm 311 and the right telescopic arm 312, and is used to detect the pressure borne by the free ends of the left telescopic arm 311 and the right telescopic arm 312, that is, to detect whether the left telescopic arm 311 and the right telescopic arm 312 support the pipe segment 01. The pressure detection member can be a pressure sensor, but is not limited thereto.

[0065] The pressure detection component is connected to the controller. When the left telescopic arm 311 and the right telescopic arm 312 support the pipe segment 01 at the same time, the pressure detection component sends a signal to the controller. The controller controls the left lifting drive component 21 and the right lifting drive component 23 to continue to rise automatically and synchronously according to the received signal, so that the left support frame 11 and the right support frame 12 drive the pipe segment 01 to continue to rise synchronously until the pipe segment 01 is separated from the pipe segment transport vehicle 03, thereby realizing automatic unloading of the pipe segment 01, further improving the degree of automation, and thus improving the efficiency.

[0066] It should be added that when the left support frame 11 and the right support frame 12 drive the segment 01 to continue to rise to the second preset height, the left support frame 11 and the right support frame 12 stop rising and falling, and the segment 01 completely leaves the segment transport vehicle 03, creating conditions for the mobile support 1 to drive the segment 01 to move along the box culvert 04. The second preset height here refers to the height when the left support frame 11 and the right support frame 12 stop upgrading.

[0071] As attached Figure 7 As shown, the lifting bracket 2 is started again, and the lifting bracket 2 continues to rise in a direction perpendicular to the box culvert 04, and the supporting bracket 3 drives the segment 01 to separate from the segment transport vehicle 03, and the segment transport vehicle 03 withdraws;

[0072] As attached Figure 8 As shown, the lifting bracket 2 is started again, and the lifting bracket 2 descends in a direction perpendicular to the box culvert 04 , and the supporting bracket 3 drives the pipe segment 01 to descend synchronously through the two telescopic arms 31 , thereby completing the unloading of the pipe segment 01 .
