[0040] In existing tunnel segment dismantling operations, manual scaffolding is often used to form temporary supports and working platforms, or mechanical equipment is used to provide supports and working platforms. The segments are then manually dismantled and transferred to transport equipment to the hoisting point to complete the dismantling of the tunnel segments. This dismantling method is time-consuming, inefficient, and the construction period cannot be guaranteed. In addition, the construction environment is relatively harsh, and workers are prone to accidental injuries during the construction process.

[0041] In view of this, the present invention proposes a segment removal device for removing multiple segments connected sequentially in a tunnel, wherein the segments are provided with mating parts. Figure 1 This is a schematic diagram of the structure of an embodiment of the segment removal equipment of the present invention; Figure 2 for Figure 1 Side view of the segment removal equipment described in the text.

[0042] Please refer to Figure 1 and Figure 2 The segment removal device 100 includes a mounting base 1, a first picking component 2, and a second picking component 3. The mounting base 1 has a driving part at its bottom, allowing it to slide within the tunnel. The first picking component 2 includes a plurality of first picking parts 21 spaced circumferentially along the mounting base 1 and arranged at an angle. Each first picking part 21 has a radial extension stroke along the tunnel. A connecting part 23 is provided at the end of each first picking part 21 away from the mounting base 1, and the connecting part 23 is detachably connected to the mating part. The second picking component 3 is fixedly connected to the mounting base 1 and spaced back-to-back from the first picking component 2. It has a vertical extension stroke and is used to remove the segments at the bottom of the tunnel.

[0043] The segment removal device 100 is equipped with a drive unit at the bottom of the mounting base 1, enabling the segment removal device 100 to move independently in the tunnel, facilitating the transportation of segments. The first picking assembly 2 is used to dismantle the segments around the tunnel periphery. The first picking assembly 2 includes multiple first picking parts 21 spaced apart circumferentially along the mounting base 1 and arranged at an angle, such that each first picking part 21 corresponds to a segment. The first picking part 21 can extend and retract radially along the tunnel to reach the position on the corresponding segment where the mating part is located, thus connecting the segment. Once the 23 unit completes its connection with the mating part, the segment can be disassembled when the first pickup part 21 is retracted. At this time, the mounting base 1 moves to the next segment under the drive of the drive unit, exposing the tunnel bottom segment at its original position. This allows the second pickup part 22 to move downwards and connect with the segment before moving upwards to complete the disassembly of the segment. Subsequently, the drive unit drives the mounting base 1 to move to the segment hoisting point, and hoisting equipment is used to lift the segment away to complete the disassembly of one ring of segments in the tunnel.

[0044] It should be noted that in other embodiments, the mounting base 1 may not be equipped with a drive unit, and the movement of the mounting base 1 may be accomplished by an external transport tool. This is merely a simple change of the transport tool and should also fall within the protection scope of this invention.

[0045] Furthermore, in this embodiment, the first pickup unit 21 is a hydraulic cylinder, the cylinder barrel of which is fixedly connected to the mounting base 1, and the connecting part 23 is located at the end of the piston rod of the hydraulic cylinder. Hydraulic cylinders are a mature technology, easy to install, and possess good load-bearing capacity and deformation resistance. While transporting the tunnel segments, they are not easily deformed by forces in various directions, resulting in better stability and a longer service life for the equipment.

[0046] Specifically, in this embodiment, the first pickup unit 21 includes a first hydraulic cylinder 211, two second hydraulic cylinders 212 and two third hydraulic cylinders 213. The first hydraulic cylinder 211 is arranged vertically, the two third hydraulic cylinders 213 are respectively disposed on both sides of the first hydraulic cylinder 211, and the two second hydraulic cylinders 212 are respectively disposed between the first hydraulic cylinder 211 and the two third hydraulic cylinders 213.

[0047] In this embodiment, the tunnel circumferential support is formed by the combination of six segments. Therefore, the first picking unit 21 is configured with five hydraulic cylinders to disassemble the five segments except for the bottom of the tunnel. Specifically, the first hydraulic cylinder 211 extends vertically to disassemble the segments at the top of the tunnel. The two third hydraulic cylinders 213 are located on both sides of the first hydraulic cylinder 211 and below the mounting base 1 to disassemble the two segments on the left and right sides below the tunnel. The two second hydraulic cylinders 212 are located on both sides of the first hydraulic cylinder 211 and between the first hydraulic cylinder 211 and the two third hydraulic cylinders 213, i.e., above the mounting base 1, to remove the segments on the left and right sides above the tunnel.

[0048] In order to adapt to the tunnel segments around the tunnel, in this embodiment, the first hydraulic cylinder 211 is arranged vertically. Taking the position of the first hydraulic cylinder 211 as the zero point, the two second hydraulic cylinders 212 are symmetrically arranged on both sides of the first hydraulic cylinder 211 and are arranged at an angle of 18° with the first hydraulic cylinder 211. The two third hydraulic cylinders 213 are symmetrically arranged on both sides of the first hydraulic cylinder 211 and are arranged at an angle of 140° with the first hydraulic cylinder 211.

[0049] It should be noted that the included angles between the first hydraulic cylinder 211, the two second hydraulic cylinders 212 and the two third hydraulic cylinders 213 can be adjusted according to the size and layout of the segments in the actual working conditions. Even changes in the included angles should fall within the scope of protection of this invention.

[0050] Furthermore, in this embodiment, the first pickup assembly 2 further includes a second pickup section 22, which includes two pickup hydraulic cylinders 214 and two drive hydraulic cylinders 215. The two pickup hydraulic cylinders 214 are respectively disposed between the two second hydraulic cylinders 212 and the two third hydraulic cylinders 213. The bottom end of the cylinder of the pickup hydraulic cylinder 214 is hinged to the mounting base 1, and the piston rod end of the pickup hydraulic cylinder 214 is provided with a connecting part 23, which is used for detachable connection with the mating part. The bottom of the cylinder of the two drive hydraulic cylinders 215 is hinged to the mounting base 1, and the piston rod ends of the two drive hydraulic cylinders 215 are respectively hinged to the cylinder of the two pickup hydraulic cylinders 214. The drive hydraulic cylinders 215 are used to drive the pickup hydraulic cylinders 214 to rotate.

[0051] The piston rod of the driving hydraulic cylinder 215 extends outward to drive the picking hydraulic cylinder 214 to rotate upward, so that the picking hydraulic cylinder 214 cooperates with the second hydraulic cylinder 212 to jointly dismantle the tunnel segment above the tunnel side; the piston rod of the driving hydraulic cylinder 215 retracts inward to drive the picking hydraulic cylinder 214 to rotate downward, so that the picking hydraulic cylinder 214 cooperates with the third hydraulic cylinder 213 to jointly dismantle the tunnel segment below the tunnel side. In this embodiment, the tunnel segment to be dismantled is relatively long except for the top segment which is shorter. Two hydraulic cylinders are used to connect the two ends of the segment respectively, making the dismantling of the segment more stable and safer.

[0052] Specifically, in this embodiment, the position of the first hydraulic cylinder 211 is 0°, and the rotation range of the pickup hydraulic cylinder 214 is greater than or equal to 50° and less than or equal to 120°. This is configured to better cooperate with the second hydraulic cylinder 212 and the third hydraulic cylinder 213.

[0053] It should be noted that with this setup, the dismantling process of the tunnel segments around the tunnel perimeter will be divided into two steps. First, the second hydraulic cylinder 212 and the picking hydraulic cylinder 214 cooperate to push the tunnel segment above the tunnel side outward a certain distance, so that the first hydraulic cylinder 211 can retract the tunnel segment at the top of the tunnel downward. Then, the picking hydraulic cylinder 214 and the second hydraulic cylinder 212 cooperate to retract the tunnel segment above the tunnel side, thus completing the dismantling of the tunnel segment above the tunnel. After the three tunnel segments are transported away, the tunnel segment dismantling equipment 100 returns to its original position, and the picking hydraulic cylinder 214 rotates downward to cooperate with the third hydraulic cylinder 213 to retract the tunnel segment below the tunnel side upward, completing the dismantling.

[0054] Furthermore, the rotation range of the picking hydraulic cylinder 214 can be adjusted according to the actual working conditions. It is only a change in the rotation range, without any other creative labor, and should also be within the scope of protection of this invention.

[0055] Furthermore, in this embodiment, the first hydraulic cylinder 211, the two second hydraulic cylinders 212, and the two pickup hydraulic cylinders 214 form a dismantling group. The dismantling group is set in two groups at intervals along the traveling direction of the mounting base 1. The two pickup hydraulic cylinders 214 in each of the two dismantling groups are fixedly connected by a connecting rod. The piston rod ends of the two driving hydraulic cylinders 215 are respectively hinged to a connecting rod.

[0056] To improve safety during segment disassembly, the two first hydraulic cylinders 211, the two second hydraulic cylinders 212, and the two pickup hydraulic cylinders 214 are all arranged in two sets at intervals along the travel direction of the mounting base 1. Correspondingly, the single-cylinder thrust and shear resistance of the two first hydraulic cylinders 211, the two second hydraulic cylinders 212, and the two pickup hydraulic cylinders 214 can be appropriately reduced to save equipment manufacturing costs. Furthermore, the two pickup hydraulic cylinders 214, which are arranged at intervals between the two disassembly sets, are fixedly connected by a connecting rod, and a driving hydraulic cylinder 215 is hinged to the middle of the connecting rod to achieve synchronous rotation of the two pickup hydraulic cylinders 214.

[0057] Furthermore, in this embodiment, the connecting part 23 includes a fixing member 231 and a connecting member 232. The fixing member 231 is used to fixably connect with the piston rods of the first hydraulic cylinder 211, the two sets of the two second hydraulic cylinders 212, the two sets of the two third hydraulic cylinders 213, and the two sets of the two driving hydraulic cylinders 215. One end of the connecting member 232 is rotatably connected to the fixing member 231, and the other end is used to detachably connect with the mating part.

[0058] The segment removal device 100 achieves a detachable connection with the segment through the connection part 23 cooperating with the mating part on the segment. The fixing member 231 and the connecting member 232 are rotatably connected, so that after the segment is removed, it can be retracted to a position that fits as close as possible to the mounting base 1 by the extension and retraction of the hydraulic cylinder, so as to avoid collision with the tunnel sidewall. The fixing member 231 and the mating part are detachably connected, so as to fix the segment to the hydraulic cylinder or remove it from the hydraulic cylinder.

[0059] Specifically, in this embodiment, for the first hydraulic cylinder 211, the center of one end face of the fixing member 231 is fixedly connected to the end face of the piston rod of the first hydraulic cylinder 211 away from the cylinder barrel, and the other end face is rotatably connected to one end face of the connecting member 232 through a lug; for the two second hydraulic cylinders 212, the two third hydraulic cylinders 213 and the two pickup hydraulic cylinders 214, two sets are arranged at intervals along the front and rear direction, one end face of the fixing member 231 is fixedly connected to the piston rod of one hydraulic cylinder in the front and rear respectively, and the other end face is rotatably connected to one end face of the connecting member 232 through a lug; in the connecting part 23, the end face of the fixing member 231 away from the connecting member 232 is provided with a lug and a through hole is provided on the lug, the mating part is a groove and a corresponding threaded hole is provided in the groove, and the connecting member 232 and the mating part are detachably connected by bolts. With this configuration, the connection or removal of the tube segment and the tube segment removal device 100 can be quickly realized.

[0060] In another embodiment, the first pickup part 21 is a telescopic member, which includes a movable rod, a telescopic motor and the connecting part 23. The movable rod is movably connected to the mounting base 1, and the telescopic motor is driven to drive the movable rod to move in its active stroke. The connecting part 23 is located at the end of the movable rod away from the mounting base 1 and is detachably connected to the mating part.

[0061] The telescopic motor drives the movable rod to move closer to the tube segment. After the connecting part 23 is fixedly connected with the mating part, the telescopic motor drives the movable rod to retract and move the tube segment to complete the disassembly of the tube segment.

[0062] Furthermore, in this embodiment, the second pickup component 3 is an electric guide chain 3a. The electric guide chain 3a includes a main body, a drive motor, a guide chain, and a fixing part. The main body is fixed to the upper end of the mounting base 1 and is spaced apart from the first pickup component 2 in the front-back direction. The drive motor is located on the main body. One end of the guide chain is connected to the drive motor, and the other end can move in the up-down direction under the drive of the drive motor. The fixing part is fixedly connected to the other end of the guide chain and is used for detachable connection with the mating part.

[0063] The first picking component 2 is used to remove the tunnel segments on the upper part of the tunnel circumference. After the removal is completed, the tunnel segment removal device 100 moves backward by a distance equal to the width of the tunnel segment to expose the tunnel segments that were originally located below the tunnel segment removal device 100. At this time, the drive motor drives the guide chain to move downward until the fixing part and the mating part complete the mating connection. The drive motor then drives the guide chain to move upward to remove the tunnel segments at the bottom of the tunnel.

[0064] It should be noted that the mating part is a groove with a threaded hole inside. The fixing part can be a ring fixedly connected to the guide chain and connected to the threaded hole by a bolt. Alternatively, the fixing part can be a bolt fixedly connected to the guide chain and directly connected to the threaded hole. In the case where a track is installed on the tunnel bottom segment, the fixing part can also be a clamping member. The clamping member has two clamps that rotate around the same axis. Pressing the two clamps causes them to open a certain distance to accommodate the track. After releasing the two clamps, the track can be clamped by the clamping member to complete the connection between the fixing part and the tunnel segment. The fixing part can be adjusted according to actual needs.

[0065] Specifically, there are two electric guide chains 3a, which are spaced apart on the mounting base 1 in the left and right direction. This arrangement makes the electric guide chains 3a more stable when disassembling the tube segments.

[0066] Furthermore, the segment removal device 100 also includes a central control component, which is disposed on the mounting base 1 and is electrically connected to the first pickup component 2 and the drive motor.

[0067] The central control component is used in conjunction with a remote control device to enable remote operation of the segment removal equipment 100, thereby improving work efficiency and further ensuring the personal safety of construction workers.

[0068] In another embodiment, the second pickup component 3 is an electric swing arm, which includes a movable swing arm, a supporting hydraulic cylinder, and a fixing member 231. The movable swing arm has a connecting end and a pickup end that are disposed opposite to each other. The connecting end is rotatably connected to the lower end of the mounting base 1 and can be rotatably disposed in the vertical direction. The cylinder of the supporting hydraulic cylinder is hinged to the mounting base 1, and the end of the piston rod away from the cylinder is hinged to the movable swing arm. The supporting hydraulic cylinder is used to drive the movable swing arm to rotate in the vertical direction. The fixing member 231 is disposed at the pickup end and is used to be detachably connected to the mating part.

[0069] After the segment removal equipment 100 removes the segments above the tunnel perimeter using the first picking component 2, it moves to the location of the next segment, exposing the segment originally located below the segment removal equipment 100. The piston rod of the supporting hydraulic cylinder retracts into the cylinder, causing the movable swing arm to rotate downwards, thereby bringing the fixing member 231 closer to the mating part and completing the mating connection. The piston rod of the supporting hydraulic cylinder extends out of the cylinder, causing the movable swing arm to rotate upwards, completing the disassembly of the segment.

[0070] Specifically, the fixing member 231 includes a flexible member and a connecting bolt. The flexible member has two opposite ends, one end of which is fixedly connected to the free end of the movable swing arm, and the other end is fixedly connected to the connecting bolt. The connecting bolt is used to mate with the mating part.

[0071] The surface of the tube segment is recessed inward to form a groove, and a threaded hole is provided in the groove to form the mating part. The connecting bolt is engaged with the threaded hole to connect the tube segment to the electric swing arm, thereby completing the disassembly.

[0072] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
