Description

Technical Field

[0001] This application relates to the field of tunnel segment unloading technology, and in particular to a segment unloading device. Background Technology

[0002] With the continuous development and construction of urban subways, intercity railways, and mountain water diversion tunnels, full-face tunnel boring machines with a diameter of 8 meters or more have been widely used. Due to the narrow space in tunnels, trackless rubber-wheeled vehicles were initially used to transport tunnel segments, and later trailers were added to travel directly on the inner wall of the tunnel.

[0003] In the existing technology, the segment unloading device is suspended on both sides of the rear-mounted trailer. The segment unloading device unloads and stores the segments on the trackless rubber-tired vehicle, and then the segment crane lifts the segments from the segment unloading device to the segment feeder or segment assembly area, and finally the assembly machine completes the assembly of the segments.

[0004] However, the segment unloading device has high requirements for the structure of the supporting trailer. The trailer frame of the supporting trailer bears the total weight of the unloader and the segment. When the unloader unloads an excessively heavy segment, it is easy for the trailer frame to deform, affecting the safety and reliability of the trailer frame operation. Utility Model Content

Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components, unless otherwise expressly limited.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] With the continuous development and construction of urban subways, intercity railways, and mountain water diversion tunnels, full-face tunnel boring machines with a diameter of 8 meters or more have been widely used. Due to the narrow space in tunnels, trackless rubber-wheeled vehicles were initially used to transport tunnel segments, and later trailers were added to travel directly on the inner wall of the tunnel.

[0039] In the existing technology, the segment unloading device is suspended on both sides of the rear-mounted trailer. The segment unloading device unloads and stores the segments on the trackless rubber-tired vehicle, and then the segment crane lifts the segments from the segment unloading device to the segment feeder or segment assembly area, and finally the assembly machine completes the assembly of the segments.

[0040] However, the segment unloading device has high requirements for the structure of the supporting trailer. The trailer frame of the supporting trailer bears the total weight of the unloader and the segment. When the unloader unloads an excessively heavy segment, it is easy for the trailer frame to deform, affecting the safety and reliability of the trailer frame operation.

[0041] This application provides a segment unloading device, which uses a traveling component installed at the bottom of an outer frame. The traveling component is placed on the tunnel, and a lifting component lifts the segments to unload them from the rubber-tired vehicle. During the unloading process, the weight of the segments is mainly supported by the outer frame and the traveling component. The connecting component is connected to the trailer frame and mainly serves to connect and move synchronously with the trailer frame, thereby reducing the weight of the segments that the trailer frame bears, reducing the possibility of trailer frame deformation, and improving the safety and reliability of the trailer frame operation.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] This application provides a segment unloading device, referring to... Figure 1 and Figure 3 The segment unloading device includes: an external frame 100;

[0044] A connection assembly 200 is disposed on the outer frame 100 for connection with the trailer frame 1;

[0045] The traveling assembly 300 is disposed at the bottom of the outer frame 100 and is used to place on the tunnel to support the outer frame 100.

[0046] Lifting assembly 400 is mounted on the outer frame 100 for lifting segments.

[0047] The segment unloading device is set to two, which are symmetrically arranged on both sides of the trailer frame 1 to assist in lifting the segments. The rubber-wheeled vehicle travels between the two segment unloading devices to unload the segments from the vehicle. The segments are then lifted from the segment unloading devices to the segment feeder or segment assembly area by the segment crane on the trailer frame 1, and finally assembled by the assembly machine.

[0048] Reference Figure 3 and Figure 4The connecting component 200 connects the outer frame 100 to the trailer frame 1, allowing the outer frame 100 to move synchronously along the tunnel with the trailer frame 1 for the gradual laying of tunnel segments. The connection between the outer frame 100 and the trailer frame 1 primarily serves to straighten the outer frame 100 and drive its movement. The weight of the tunnel segments borne by the outer frame 100 is mainly concentrated on the traveling component 300, thereby reducing the stress on the trailer frame 1, preventing deformation of the trailer frame 1 under heavy loads, and improving the safety and reliability of the trailer frame 1 during operation.

[0049] In one possible implementation, refer to Figure 1 and Figure 3 The lifting assembly 400 includes an inner frame 410, a lifting cylinder 420, and a pawl 430. The inner frame 410 is slidably mounted on the outer frame 100. The lifting cylinder 420 is mounted on the outer frame 100 and connected to the inner frame 410 to drive the inner frame 410 to rise and fall. The pawl 430 is mounted on the inner frame 410 to support the segments.

[0050] In one possible implementation, the outer frame 100 includes a crossbeam 110 and two support legs 120, the two support legs 120 being fixed at both ends of the crossbeam 110, and the lifting assembly 400 is configured in two sets, the two sets of lifting assemblies 400 being respectively disposed at both ends of the crossbeam 110 and connected to the inner frame 410.

[0051] Two support legs 120 are welded and fixed to the ends of the crossbeam 110, making the outer frame 100 form a "door" shape, with the inner frame 410 located between the two support legs 120. There is a gap between the crossbeam 110 and the inner frame 410, and even after the lifting assembly 400 lifts the segment, there is still a gap between the inner frame 410 and the crossbeam 110 to provide space for the mechanical claw of the segment crane to move and avoid interference with the segment crane.

[0052] Specifically, the lifting cylinder 420 is fixed to the top of the outer frame 100, and a cylinder seat is fixed to the top of the outer frame 100. The lifting cylinder 420 is installed on the cylinder seat and is arranged in a vertical direction. The piston rod of the lifting cylinder 420 is fixedly connected to the inner frame 410 so as to drive the inner frame 410 to slide in a vertical direction to lift the inner frame 410.

[0053] The inner frame 410 is a steel frame structure, and two lifting cylinders 420 are fixedly connected to the inner frame 410 to drive the inner frame 410 to move between the two support legs 120. The setting of the two lifting cylinders 420 helps to improve the stability of the movement of the inner frame 410 and increase the load-bearing capacity of the overall device, so as to lift the heavier segments.

[0054] In one possible implementation, refer to Figure 1 , Figure 5 and Figure 6 The lifting assembly also includes a rotating component 440, which is mounted on the outer frame 100 and connected to a pawl 430 to drive the pawl 430 to rotate.

[0055] The rotating component 440 allows for the rotation of the pawl 430. When it is necessary to lift the segment, the pawl 430 is rotated out to the underside of the segment to lift it. After lifting is completed, the rotating component 440 rotates the pawl 430 to the inside of the outer frame 100, thereby reducing the volume occupied by the entire device and facilitating the passage of vehicles transporting the segments.

[0056] In one possible implementation, the rotating component 440 includes a swing cylinder 441, a rotating shaft 442 is provided on the pawl 430, the rotating shaft 442 is rotatably connected to the inner frame 410, the swing cylinder 441 is hinged to the inner frame 410 and hinged to the rotating shaft 442 to drive the rotating shaft 442 to rotate.

[0057] Specifically, a connecting sleeve is fixed on the inner frame 410, and a rotating shaft 442 is rotatably connected inside the connecting sleeve. Both ends of the rotating shaft 442 extend outside the connecting sleeve. The bottom of the rotating shaft 442 is fixedly connected to the pawl 430, and the top of the rotating shaft 442 is hinged to the piston rod of the swing cylinder 441 through a hinge body. The swing cylinder 441 is arranged horizontally and is hinged on the inner frame 410. By retracting the swing cylinder 441, the rotating shaft 442 is driven to rotate, thereby adjusting the position of the pawl 430 to reduce the space occupied by the pawl 430, so as to facilitate the passage of vehicles transporting tunnel segments in the tunnel.

[0058] Furthermore, the inner frame 410 has two rotating parts 440 and two pawls 430, with the two pawls 430 corresponding to the two lifting cylinders 420, in order to improve the overall load-bearing capacity of the device and the stability of the segment lifting.

[0059] In one possible implementation, refer to Figure 1 and Figure 3 The connecting assembly 200 includes two sets of connectors, which are symmetrically arranged. Each connector includes a hinge seat 210, a connecting shaft 220, and a mounting seat 230. The hinge seat 210 is mounted on the outer frame 100, the connecting shaft 220 is mounted on the hinge seat 210, and the mounting seat 230 passes through the connecting shaft 220. The two mounting seats 230 are used to symmetrically clamp onto the trailer frame 1.

[0060] Each of the two support legs 120 is equipped with two sets of connecting components 200 to improve the stability of the connection. A hinge seat 210 is welded and fixed to the support leg 120. A connecting shaft 220 passes through the hinge seat 210, and a mounting seat 230 passes through the connecting shaft 220. A hinge is formed between the mounting seat 230 and the connecting shaft 220, allowing the mounting seat 230 to rotate and adjust its angle. One end of the mounting seat 230 is a flat surface, used to connect with the trailer frame 1. Furthermore, the flat surfaces on the two mounting seats 230 respectively abut against one of the transverse beams in the trailer frame 1, clamping the transverse beam and thus connecting the outer frame 100 to the trailer frame 1.

[0061] Furthermore, the mounting base 230 is welded and fixed to the trailer frame 1.

[0062] Furthermore, refer to Figure 1 and Figure 2 The mounting base 230 is provided with a waist-shaped hole 231, and the connecting shaft 220 is slidably disposed in the waist-shaped hole 231 in the vertical direction. The mounting base 230 is used to connect with the trailer frame 1.

[0063] The connecting shaft 220 can slide within the oblong hole 231, which facilitates the adjustment of the positional relationship between the support leg 120 and the support leg 120 of the trailer frame 1. When encountering up-and-down bumps or steps in the tunnel, the trailer frame 1 moves the outer frame 100 during travel. When the outer frame 100 passes through the steps, the oblong hole 231 provides vertical displacement for the support leg 120, which improves the applicability of the device and eliminates the need for manual adjustment.

[0064] In one possible implementation, each of the two support legs 120 is provided with a guide groove 121, and the two ends of the inner frame 410 are respectively slidably disposed between the guide grooves 121 of the two support legs 120.

[0065] Guide grooves 121 are provided on the side of each of the two support legs 120 that are close to each other, and the inner frame 410 is slidably connected between the two guide grooves 121. The guide grooves 121 provide guidance for the movement of the inner frame 410 to improve the smoothness of the sliding of the inner frame 410.

[0066] In one possible implementation, refer to Figure 1 and Figure 3 The traveling assembly 300 includes rollers, which are rotatably mounted on the bottom of the outer frame 100 and are used to roll on the tunnel.

[0067] Two rollers are provided, each rotatably connected to the bottom of one of the two support legs 120. This serves to support the outer frame 100 and concentrate the weight of the tunnel segments onto the tunnel.

[0068] Furthermore, the rotation axis of the roller has an angle with the outer frame 100 to ensure that the roller fits snugly against the tunnel. That is, the rotation axis of the roller is parallel to the tangent of the tunnel at the location of the roller, in order to improve the load-bearing capacity of the roller and reduce damage to the roller.

[0069] For example, roller skates can also be used instead of wheels, which will not be elaborated on here.

[0070] The tunnel segment unloading device provided in this application embodiment uses a traveling component 300 installed at the bottom of an outer frame 100. The traveling component 300 is placed on the tunnel, and a lifting component 400 lifts the tunnel segments to unload them from the rubber-tired vehicle. During the unloading process, the weight of the tunnel segments is mainly supported by the outer frame 100 and the traveling component 300. The connecting component 200 is connected to the trailer frame 1 and mainly serves to connect and move synchronously with the trailer frame 1, thereby reducing the weight of the tunnel segments that the trailer frame 1 bears, reducing the possibility of deformation of the trailer frame 1, and improving the safety and reliability of the trailer frame 1 during operation.

[0071] Finally, it should be noted that other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein.
