In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.
[0038] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.
[0039] like Figures 1 to 5 As shown, the present application provides a cable moving device 100 for a tunnel boring machine, comprising a moving structure 10, a accommodating component 20 and a cable clamp group 30. The moving structure 10 comprises a sliding member 11 and a slide rail 12. The sliding member 11 is slidably connected to the slide rail 12. The sliding member 11 is suitable for being connected to a cable 200 and capable of dragging the cable 200 to move. The accommodating component 20 is detachably connected to the slide rail 12. The cable clamp group 30 comprises a plurality of cable clamps 31. The plurality of cable clamps 31 are hinged to each other. The cable clamps 31 are suitable for being connected to the cable 200 and wrapping the cable 200. A accommodating groove 24 extending in a direction parallel to the slide rail 12 is provided in the accommodating component 20, and the cable clamp group 30 is arranged in the accommodating groove 24.
[0040] Through the above technical solution, the cable clamp 31 is designed to connect with the cable 200 and wrap around the cable 200, so that the cable clamp 31 can protect the cable 200. In addition, the present disclosure also provides a receiving component 20, which has a receiving groove 24. The receiving groove 24 can accommodate the cable clamp assembly 30 to limit the movement of the cable 200. Since the cable clamp 31 and the receiving groove 24 are in direct contact when the movable structure 10 drags the cable 200, the cable clamp 31 and the cable 200 are relatively stationary, thereby protecting the cable 200 from damage during the dragging.
[0041] A tunnel boring machine (TBM) is a highly integrated engineering machine primarily used for excavation operations in underground mines, tunnels, subways, and other underground projects, and it possesses multiple functions. During operation, the TBM requires a cable 200 to provide power to the TBM. Because the TBM needs to move in multiple directions, the cable 200 must be driven to move with the TBM. Therefore, a mobile structure 10 is provided to move with the TBM. The cable 200 can move with the movement of the mobile device, thereby ensuring power to the TBM during operation.
[0042] In order to make the movement of the movable structure 10 more stable, a sliding member 11 and a sliding rail 12 are provided to cooperate with each other, wherein the sliding rail 12 can be fixedly installed relative to the working reference surface (such as the foundation surface), and the sliding member 11 can move on the sliding rail 12, and the cable 200 can follow the movement of the sliding member 11.
[0043] In the present disclosure, hinged cable clamps 31 are provided so that two adjacent cable clamps 31 can rotate relative to each other. The cable clamps 31 protect the cable 200 while not restricting the bending of the cable 200, thereby ensuring that the cable 200 can move flexibly with the tunnel boring machine. In addition, the function of the accommodating component 20 is to accommodate the cable 200 and the cable clamp assembly 30. Since the tunnel boring machine will pull the cable 200 when it moves, if the cable 200 is not restricted, it may be pulled to a far position. Pulling the cable 200 to a far position not only damages the cable 200, but also takes more time and effort to pull the cable 200. Therefore, such a setting can facilitate the pulling of the cable 200.
[0044] The hinge may be a suitable structure such as a pin hinge, a rotary hinge, etc., and the present disclosure does not limit this.
[0045] In this disclosure, Figure 2 As shown, the sliding member 11 may further include a driving member, the sliding member 11 including a sliding wheel 111, and the driving member drives the sliding wheel 111 to roll on the slide rail 12. With this arrangement, the sliding member 11 is provided with a driving member, so that the sliding member 11 can move automatically, reducing manual operation, freeing up labor, and improving efficiency. Furthermore, the sliding wheel 111 is provided on the sliding member 11 to roll on the slide rail 12, and the rolling friction is configured to reduce friction, making the movement of the sliding member 11 more convenient.
[0046] The driving member may be a motor or other structure capable of providing power, which is not limited in this disclosure.
[0047] In this disclosure, Figure 1 and Figure 2 As shown, the sliding member 11 may further include two limit plates 112, which are arranged at both ends of the sliding wheel 111 along the axis of the sliding wheel 111. The gap between the two limit plates 112 is adapted to the width of the slide rail 12, and the limit plates 112 extend to the side of the slide rail 12. This arrangement can prevent the sliding wheel 111 from falling off the surface of the slide rail 12 when rolling on the slide rail 12.
[0048] Since the gap between the two limit plates 112 is adapted to the width of the slide rail 12, the gap between the two limit plates 112 can be slightly larger than the width of the slide rail 12, and the limit plates 112 extend to the side of the slide rail 12, which is equivalent to clamping the upper part of the slide rail 12 between the two limit plates 112. Since the sliding wheel 111 is arranged between the two limit plates 112, such a setting can limit the trajectory of the sliding wheel 111, thereby preventing the sliding wheel 111 from falling off the slide rail 12 or deviating from the trajectory.
[0049] like Figure 2As shown, the rotating shaft of the sliding wheel 111 can be passed through the two limiting plates 112 to facilitate the installation of the sliding wheel 111.
[0050] In some embodiments, a groove suitable for the sliding wheel 111 to roll can be provided on the slide rail 12, so that the sliding wheel 111 rolls in the groove to limit the rolling track of the sliding wheel 111, thereby preventing the sliding wheel 111 from falling off the slide rail 12 or deviating from the track.
[0051] In this disclosure, Figure 1 and Figure 2 As shown, the sliding member 11 may include a connecting portion 113, which is connected to the sliding wheel 111 and can move along the sliding rail 12 with the sliding wheel 111. The connecting portion 113 is connected to the cable clamp 31 and is connected to the cable 200 through the cable clamp 31. In this way, the connection between the connecting portion 113 and the cable 200 is facilitated, thereby ensuring that the movable structure 10 can drive the cable 200 to move.
[0052] like Figure 1 and Figure 2 As shown, the connection portion 113 and the cable clamp 31 are rotatably connected, such as hinged, so that the angle between the two at the connection is not limited and various bending angle requirements of the cable 200 can be met.
[0053] In this disclosure, Figure 3 and Figure 4 As shown, the cable clamp 31 may include a body 312 and a connecting plate 313. The body 312 has a cavity 311 for the cable 200 to pass through. The connecting plate 313 is detachably connected to the body 312 and is connected to the cavity 311 to fix the cable 200. In this way, the connection between the cable 200 and the cable clamp 31 can be facilitated.
[0054] Among them, the cavity 311 on the cable clamp 31 is used to accommodate the cable 200, and the connecting plate 313 and the main body 312 are detachably connected. After the cable 200 is placed in the cavity 311, the connecting plate 313 is connected to the main body 312, which can tighten and fix the cable 200, thereby ensuring the connection between the cable 200 and the cable clamp 31.
[0055] In this disclosure, Figure 3 As shown, the connecting plate 313 and the body 312 can be connected by a latch 314. In this way, the connection between the two is convenient, the production is simple, and the cost is low.
[0056] In some embodiments, the connecting plate 313 and the main body 312 may be connected via suitable connecting members such as bolts 40 or screws.
[0057] In this disclosure, Figure 5As shown, the receiving member 20 may include a bottom plate 21, side rails 22, and a connecting side plate 23. The side rails 22 are disposed on a first side of the bottom plate 21, and the connecting side plate 23 is disposed on a second side of the bottom plate 21 opposite the first side. A receiving groove 24 is formed between the side rails 22, the bottom plate 21, and the connecting side plate 23. The receiving groove 24 is used to accommodate the cable clamp assembly 30. This arrangement ensures that both sides of the receiving groove 24 have limiting side edges, namely the side rails 22 and the connecting side plate 23, thereby ensuring the stability of the cable clamp assembly 30 placed in the receiving groove 24.
[0058] In some embodiments, the width of the bottom plate 21 can be slightly larger than the width of the cable clamp 31 to facilitate the placement of the cable clamp assembly 30. At the same time, the movement trajectory of the cable 200 and the cable clamp assembly 30 during dragging can be restricted to the interior of the receiving groove 24, thereby preventing the long cable 200 from getting entangled. As the excavator moves forward and backward, the cable 200 as a whole can slide smoothly within the receiving groove 24 as the excavator moves forward and backward.
[0059] In this disclosure, Figure 2 As shown, the connecting side plate 23 can be connected to the slide rail 12 by bolts 40. In this way, the installation and removal of the receiving component 20 can be facilitated.
[0060] In this disclosure, Figure 5 As shown, the side of the side rail 22 near the bottom plate 21 can be arranged perpendicular to the bottom plate 21, and the side of the connecting side plate 23 near the bottom plate 21 can be arranged perpendicular to the bottom plate 21. In this way, the width of the bottom position of the receiving groove 24 is determined, which helps prevent the cable clamp assembly 30 from shaking to the rear side of the receiving groove, thereby reducing friction damage to the cable 200.
[0061] In some embodiments of the present disclosure, the upper opening of the receiving groove 24 may be slightly larger than the bottom position, so as to facilitate the placement of the cable 200.
[0062] The cable 200 and the cable clamp assembly 30 can be stacked in an "S" shape in the receiving groove 24, such as Figure 3 As shown, laying the cable 200 in this way can facilitate the back and forth movement of the excavator and prevent the cable 200 from being entangled when being dragged. The cable 200 and the cable clamp assembly 30 can form a reliable whole after being arranged to overcome common "pulling", "bending", "hanging", "smashing" and "squeezing" actions.
[0063] In this disclosure, Figure 5As shown, the number of accommodating components 20 can be multiple, each connected to the slide rail 12, and the multiple accommodating components 20 are spliced end to end along the extension direction of the slide rail 12. This can reduce the volume and weight of a single accommodating component 20, thereby facilitating the installation of the accommodating components 20. Furthermore, an appropriate number of accommodating components 20 can be installed based on the movement requirements of the tunnel boring machine, making the cable moving device 100 more widely applicable.
[0064] In the present disclosure, the design and manufacture of the accommodation component 20 and the mobile structure 10 can be adapted to local conditions, so that the cable 200 can be moved forward and backward randomly during the advance and retreat of the tunnel boring machine. While ensuring the safety of the equipment, there is no need to assign a dedicated person to drag and guard the cable 200, which can free up labor.
[0065] In actual applications, the cable 200 can also be replaced by a water pipe or other components that need to move with the movement of the tunnel boring machine.
[0066] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0067] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction, and the present disclosure will not further explain various possible combinations.
[0068] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
