DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] The present application provides a segment erector, which is used in a tunneling device such as a shield tunneling machine, and is used for assembling segments in a tunnel to form a tunnel lining during tunnel excavation construction.

[0027] As Figure 1 and Figure 2As shown, the pipe segment assembling machine provided by the utility model comprises a grabbing assembly 100 and a moving assembly. Wherein, the grabbing assembly 100 is used for grabbing the pipe segment 700, the moving assembly is used for driving the grabbing assembly 100 to change position, and the grabbing assembly 100 and the moving assembly are mutually matched, so that the pipe segment 700 can be grabbed, moved or assembled.

[0028] As shown in the figure, Figure 2 The grabbing assembly 100 comprises a grabbing disc 110, a grabbing and clamping driving mechanism 130 is fixedly installed on the grabbing disc 110, and the grabbing and clamping driving mechanism 130 is hinged with a grabbing and clamping piece 120. The grabbing and clamping driving mechanism 130 drives the grabbing and clamping piece 120 to move, so as to clamp the pipe segment 700.

[0029] It can be understood that the moving assembly needs to drive the pipe segment 700 to perform a series of actions such as translation, lifting and rotation, so as to complete the assembly. Correspondingly, the moving assembly comprises a walking driving assembly 300, a lifting driving assembly 400 and a rotating driving assembly 500.

[0030] In addition to the above structure, the pipe segment assembling machine further comprises an adjusting assembly 600. The adjusting assembly 600 is used for finely adjusting the position or direction of the pipe segment 700, so as to adjust the pipe segment 700 during the grabbing, moving, transporting or assembling of the pipe segment 700, and realize more accurate and efficient assembly.

[0031] In order to achieve the above purpose, the adjusting assembly 600 is connected with the moving assembly and movably connected with the grabbing assembly 100. The adjusting assembly 600 is connected with the moving assembly, so as to move with the moving assembly. Wherein, the adjusting assembly 600 can be fixedly connected with the moving assembly, or movably connected with the moving assembly. In the case that the adjusting assembly 600 is movably connected with the moving assembly, one degree of freedom can be added in the process of assembling the pipe segment 700, so as to realize more flexible adjustment. The adjusting assembly 600 is movably connected with the grabbing assembly 100, so that the grabbing assembly 100 can move relative to the adjusting assembly 600 and change the relative position or direction with the moving assembly, thereby changing the pose of the adjusting assembly 100 relative to the moving assembly. Preferably, the adjusting assembly 600 comprises a knuckle bearing, and the grabbing assembly 100 is hinged with the knuckle bearing.

[0032] As shown in the figure, Figure 2 And Figure 3 As shown in the figure, the pipe segment assembling machine further comprises a main beam 200. The main beam 200 is arranged along the advancing direction of the pipe segment assembling machine, and is used for supporting and fixing the walking driving assembly 300, the lifting driving assembly 400 and the rotating driving assembly 500 and the like. Specifically, the main beam 200 comprises a beam body 210 and a support leg 220. At least part or all of the moving assembly is fixed to the beam body 210, and the support leg 220 is connected with the beam body 210 to support the beam body 210.

[0033] The number of the main beams 200 can be two or more arranged side by side, or one. For a small shield, the space utilization needs to be more intensive due to the smaller internal space, and therefore, the number of the main beams 200 is preferably one.

[0034] As shown in FIGS. 1 and 2, the number of the main beams 200 is one, and the walking driving assembly 300 and the lifting driving assembly 400 are symmetrically arranged on the left and right sides of the main beam 200 and the rotating driving assembly 500. Figure 4 As shown in FIGS. 1 and 2, the number of the main beams 200 is one, and the walking driving assembly 300 and the lifting driving assembly 400 are symmetrically arranged on the left and right sides of the main beam 200 and the rotating driving assembly 500. Figure 5 As shown in FIGS. 1 and 2, the number of the main beams 200 is one, and the walking driving assembly 300 and the lifting driving assembly 400 are symmetrically arranged on the left and right sides of the main beam 200 and the rotating driving assembly 500.

[0035] For example, the number of the walking driving assembly 300 and the lifting driving assembly 400 is two. The walking driving assembly 300 and the lifting driving assembly 400 are arranged at the front and back ends of the rotating driving assembly 500.

[0036] The number of the main beams 200 is one, and the walking driving assembly 300 and the lifting driving assembly 400 are symmetrically arranged on the left and right sides of the main beam 200 and the rotating driving assembly 500, which can reduce the size of the segmental assembling machine, improve the space utilization, and ensure that the moving assembly can drive the grabbing assembly 100 to move more smoothly.

[0037] As shown in FIGS. 1 and 2, the number of the main beams 200 is one, and the walking driving assembly 300 and the lifting driving assembly 400 are symmetrically arranged on the left and right sides of the main beam 200 and the rotating driving assembly 500. Figures 1 to 3 The walking driving assembly 300 is used to drive the grabbing assembly 100 to move along the axial direction of the main beam 200; the lifting driving assembly 400 is used to drive the grabbing assembly 100 to lift relative to the main beam 200; and the rotating driving assembly 500 is used to drive the grabbing assembly 100 to rotate around the main beam 200.

[0038] At least part of the walking driving assembly 300 is connected with the main beam 200 and can move along the axial direction of the main beam 200. The rotating driving assembly 500 is connected with the walking driving assembly 300, thereby following the walking driving assembly 300 to move along the axial direction of the main beam 200. The lifting driving assembly 400 is connected with the rotating driving assembly 500, thereby following the rotation of the rotating driving assembly 500 to rotate synchronously. The adjusting assembly 600 is connected with the lifting driving assembly 400, thereby following the lifting of the lifting driving assembly 400 to lift together.

[0039] Specifically, the walking driving assembly 300 is connected with the beam body 210, and the rotating driving assembly 500 is sleeved on the outer periphery of the beam body 210. The rotating driving assembly 500 comprises a fixed part 510 which is fixed, and a rotating part 520 which can rotate relative to the fixed part 510. The fixed part 510 is connected with the walking driving assembly 300, and the rotating part 520 is arranged on the fixed frame 510 and can rotate around the main beam 200. The lifting driving assembly 400 is installed on the rotating frame 520. The adjusting assembly 600 is fixedly connected or movably connected with the lifting driving assembly 400.

[0040] The walking driving assembly 300 is indirectly connected with the grabbing assembly 100 through the rotating driving assembly 500, the lifting driving assembly 400 and the adjusting assembly 600 in sequence. The walking driving assembly 300 can actively provide driving force to drive itself and the rotating driving assembly 500, the lifting driving assembly 400, the adjusting assembly 600 and the grabbing assembly 100 which are directly or indirectly connected with the walking driving assembly 300 to reciprocally walk along the extension direction of the beam body 210 of the main beam 200. The walking driving assembly 300 drives the grabbing assembly 100 to walk forward and backward, and can endow the segmental pipe assembling machine with a first degree of freedom. The lifting driving assembly 400 can be lifted to drive the adjusting assembly 600 and the grabbing assembly 100 to move up and down. The lifting driving assembly 400 drives the grabbing assembly 100 to move up and down, and can endow the segmental pipe assembling machine with a second degree of freedom. The rotating driving assembly 500 can be rotated to drive the lifting driving assembly 400, the adjusting assembly 600 and the grabbing assembly 100 to rotate around the beam body 210. The rotating driving assembly 500 drives the grabbing assembly 100 to rotate circumferentially, and can endow the segmental pipe assembling machine with a third degree of freedom.

[0041] Through the above structure, the grabbing assembly 100 which grabs the segmental pipe 700 can be driven to flexibly walk forward and backward, to lift up and down, and to rotate and assemble, and after completing an assembling action, the grabbing assembly 100 can be driven to reset to the trolley position where the segmental pipe 700 to be assembled is placed, and the grabbing, moving and assembling can be repeatedly performed again.

[0042] In the above process, since the grabbing assembly 100 is movably connected with the adjusting assembly 600, the grabbing assembly 100 can be relatively and slightly adjusted in position or direction in any forward and backward walking, up and down lifting and rotating and assembling action, so as to accurately and efficiently assemble.

[0043] The walking driving assembly 300 further comprises a walking piece, the rotating driving assembly 500 is connected with the walking piece, and the walking piece can walk along the main beam 200. The walking piece is used to help the rotating driving assembly 500 and the lifting driving assembly 400, the adjusting assembly 600 and the grabbing assembly 100 connected with the rotating driving assembly 500 to move stably.

[0044] As Figures 3 to 5As shown, the two sides of the main beam 200 are symmetrically provided with the tracks 230, and the walking member includes the walking wheels 340. The grabbing assembly 100 is connected with the walking wheels 340, and the walking wheels 340 are embedded in the tracks 230 to roll and walk along the tracks 230. By arranging the walking wheels 340 and connecting the grabbing assembly 100 with the walking wheels 340, the grabbing assembly 100 can be driven to move along the main beam 200 stably by the rolling and walking of the walking wheels 340 along the tracks 230, so that the stable transportation of the segment 700 is realized by a simple and compact structure, and the segment 700 can be assembled accurately.

[0045] The tracks 230 are arranged on the left and right sides of the main beam 200, which can be mounted on the main beam 200 or integrally manufactured with the main beam 200 by cutting. The tracks 230 can be protruded relative to the surface of the main beam 200 or recessed relative to the surface of the main beam 200. The shape and size of the walking wheels 340 are matched with the shape and size of the tracks 230, and the walking wheels 340 are embedded in the space surrounded by the tracks 230.

[0046] Preferably, the number of the main beams 200 is one, the two sides of the main beam 200 are symmetrically provided with the tracks 230, and the number of the walking driving assemblies 300 is even, which are symmetrically arranged on the opposite sides of the main beam 200. The tracks 230 and the walking wheels 340 symmetrically arranged on the two sides of the main beam 200 can assist the rotation driving assembly 500 to move more stably.

[0047] As shown in the figure, Figure 4 The track 230 includes the bottom wall 231 and the side wall 232, and the two side walls 232 are arranged on the two sides of the bottom wall 231 to surround the space for accommodating the walking wheels 340 with the bottom wall 231. The walking wheels 340 are in abutting contact with the bottom wall 231 and the side wall 232, respectively.

[0048] The rotating part 520 of the rotation driving assembly 500 needs to rotate to drive the lifting driving assembly 400, the adjusting assembly 600 and the grabbing assembly 100 to rotate, so that the walking wheels 340 embedded in the tracks 230 are arranged in abutting contact with the bottom wall 231 and the side wall 232, respectively, to provide a reaction force for the rotation driving assembly 500 during the rotation of the rotation driving assembly 500, so as to ensure that the rotation driving assembly 500 can stably drive the lifting driving assembly 400, the adjusting assembly 600 and the grabbing assembly 100 to rotate.

[0049] The walking wheel 340 is a roller bearing. The roller bearing is stable, has a low friction coefficient, can bear heavy load and impact load, and has low replacement and maintenance cost.

[0050] As shown in the figure, Figure 6As shown, the walking wheel 340 comprises a main roller bearing 341 and a side roller bearing 342. The outer ring of the main roller bearing 341 is embedded in the track 230. The side roller bearing 342 is installed in the main roller bearing 341 and connected with the main roller bearing 341. The grabbing assembly 100 is connected with the side roller bearing 342.

[0051] The main roller bearing 341 and the side roller bearing 342 can each have a shaft head, and the two shaft heads are arranged in different directions. The main roller bearing 341 and the side roller bearing 342 can each have a bearing inner ring and a bearing outer ring, and the bearing inner ring and the bearing outer ring have rolling elements such as balls therebetween.

[0052] The main roller bearing 341 is used to realize the rolling of the walking wheel 340, and the side roller bearing 342 is used to limit the rolling direction during the rolling walking of the walking wheel 340, so as to ensure smooth rolling along a straight line. Exemplarily, the main roller bearing 341 can be a full-roller bearing, and the side roller bearing 342 can adopt a full-needle design without an inner ring, and a core shaft is used to replace the inner ring and the shaft head to achieve bearing.

[0053] As shown, Figure 6 The roller bearing further comprises a cover plate 343, which connects and fixes the main roller bearing 341 and the side roller bearing 342. The cover plate 343 is used to fix the side roller bearing 342 and the main roller bearing 341 together by nuts and threaded glue. The walking wheel 340 can also have a sealing structure, and its interior is filled with lubricating grease to provide long-term lubrication.

[0054] As shown, Figures 3 to 5 The walking member further comprises a connecting plate 350. One side of the connecting plate 350 is connected with the walking wheel 340, and the other side is connected with the rotary driving assembly 500. In other words, the walking wheel 340 and the rotary driving assembly 500 are connected through the connecting plate 350. Specifically, the side roller bearing 342 of the walking wheel 340 is connected with the fixed part 510 of the rotary driving assembly 500 through the connecting plate 350.

[0055] The connecting plate 350 can be formed in any shape such as a cuboid, a cube, a cylinder or a circular truncated cone, and its function is to connect and fix the rotary driving assembly 500, so that the rolling walking of the walking wheel 340 can drive the rotary driving assembly 500 to move back and forth. Specifically, the fixed part 510 of the rotary driving assembly 500 is connected and fixed on the connecting plate 350.

[0056] The walking driving mechanism 310 is a power supply component, and the walking member composed of the walking wheel 340 and the connecting plate 350 is an auxiliary moving component. By arranging the walking wheel 340 and the connecting plate 350, the rotary driving assembly 500 can be supported and fixed, and a guiding function can be provided to drive the rotary driving assembly 500 to walk smoothly.

[0057] As mentioned above, the segment assembly machine also includes a rotary drive assembly 500. The rotary drive assembly 500 drives the gripping assembly 100 to rotate around the main beam 200. The rotary drive assembly 500 includes a fixed part 510 and a rotating part 520. The side roller bearings 342 of the traveling wheels 340 are connected to the fixed part 510 of the rotary drive assembly 500 via a connecting plate 350. The rotating part 520 is connected to the fixed part 510 and is capable of rotating around the main beam 200. The rotary drive assembly 500 is connected to the gripping assembly 100. The lifting drive mechanism 410 of the lifting drive assembly 400 is fixedly connected to the rotating part 520, and the telescopic rod 420 of the lifting drive assembly 400 is hinged to the lifting drive mechanism 410. The telescopic rod 420 is connected to the adjusting assembly 600, thereby indirectly connecting the gripping assembly 100 and the lifting drive assembly 400.

[0058] In one example, the fixed part 510 and the rotating part 520 are connected by a flange, and both have bearings inside, with the fixed part 510 used to fix the bearings. In another example, the fixed part 510 and the rotating part 520 are connected by a slewing bearing.

[0059] As mentioned above, the segment assembly machine also includes a lifting drive assembly 400, which drives the gripping assembly 100 to move up and down relative to the main beam 200. The lifting drive assembly 400 is connected to the rotation drive assembly 500, and the gripping assembly 100 is connected to the lifting drive assembly 400.

[0060] like Figure 2 As shown, the lifting drive assembly 400 includes a lifting drive mechanism 410 and a telescopic rod 420. One end of the lifting drive mechanism 410 is connected to the rotation drive assembly 500, and the other end is hinged to the telescopic rod 420. The end of the telescopic rod 420 away from the lifting drive mechanism 410 is connected to the adjustment assembly 600.

[0061] The lifting driving mechanism 410 can be a cylinder or an electric push rod. Since one end of the lifting driving mechanism 410 is connected with the rotating driving assembly 500, the lifting driving mechanism 410 can rotate with the rotating driving assembly 500. Specifically, the lifting driving mechanism 410 is fixedly connected with the rotating part 520 of the rotating driving assembly 500. Since the other end of the lifting driving mechanism 410 is hingedly connected with the telescopic rod 420, and one end of the telescopic rod 420 away from the lifting driving mechanism 410 is connected with the adjusting assembly 600, through the cooperation of the lifting and lowering action of the lifting driving mechanism 410 and the telescopic action of the telescopic rod 420, the adjusting assembly 600 can be slightly swung left and right, and the adjusting assembly 600 drives the grabbing assembly 100 to adjust the pose. It can be understood that in the case that two lifting driving assemblies 400 are symmetrically arranged on both sides of the beam body 210 of the main beam 200, at least one of the lifting driving assemblies 400 has a telescopic rod 420. The lifting driving mechanism 410 and the telescopic rod 420 cooperate to swing the grabbing assembly 100 left and right, and can give the segment erector a fourth degree of freedom.

[0062] The walking driving assembly 300 further comprises a power supply part. The power supply part is used to provide power for driving the walking wheels 340 to roll and walk along the track 230. Specifically, as shown in Figure 1 、 Figure 4 and Figure 5 , the power supply part comprises a walking driving mechanism 310, a gear 320 and a rack 330. The rack 330 is arranged along the axial direction of the main beam 200, the walking driving mechanism 310 has a power output shaft, the gear 320 is in transmission connection with the power output shaft and is in meshing connection with the rack 330. Thus, the walking driving mechanism 310 provides power to drive the gear 320 to rotate, and the above structure makes the gear 320 rotate and walk along the rack 330 in meshing connection with the gear 320, and finally makes the walking driving mechanism 310 drive the grabbing assembly 100 to move along the axial direction of the main beam 200.

[0063] Since the rotating driving assembly 500 is connected with the walking driving assembly 300, the rotating walking of the gear 320 can drive the rotating driving assembly 500 to move back and forth, and further drive the lifting driving assembly 400, the adjusting assembly 600 and the grabbing assembly 100 directly or indirectly connected with the rotating driving assembly 500 to reciprocate along the extension direction of the beam body 210 of the main beam 200.

[0064] The driving mode structure of the gear 320 and the rack 330 is simple, small in size and low in cost, which can not only realize stable movement of the grabbing assembly 100, but also is especially suitable for small shield equipment.

[0065] The walking driving mechanism 310 is specifically a motor. Preferably, the walking driving mechanism 310 is a servo motor. The servo motor can accurately control the speed and acceleration, realize high-precision movement control, and has excellent response speed, can be quickly started, stopped and reversed, and improves the dynamic performance of the system.

[0066] Preferably, the walking driving assembly 300 further comprises a speed reducer 360, and the walking driving mechanism 310 and the gear 320 are drivingly connected through the speed reducer 360. The speed reducer 360 can reduce the rotating speed of the walking driving mechanism 310, increase the output torque, and also provide more stable and controllable transmission effect. By adjusting the transmission ratio of the speed reducer, more fine movement speed adjustment can be realized.

[0067] The rack 330 can be arranged on the main beam 200 or separately arranged relative to the main beam 200, as long as the extending direction is consistent with the extending direction of the main beam 200. Preferably, the rack 330 is arranged on the main beam 200 to achieve the purpose of simplifying the structure and stably fixing the rack 330 to ensure the smooth movement of the gear 320. It can be understood that the number and arrangement position of the rack 330 are adapted to the gear 320. When the gear 320 is symmetrically arranged on the left and right sides, the rack 330 is symmetrically arranged on the left and right sides of the main beam 200.

[0068] The embodiment also provides a tunneling equipment comprising the segment erector according to any one of the above technical solutions, and therefore has all the beneficial effects of the segment erector according to any one of the above technical solutions, which will not be repeated here. The tunneling equipment is preferably a shield tunneling machine.

[0069] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
