Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine (TBM) construction technology, specifically to a disassembly and transportation device for assembled propulsion hydraulic cylinders. Background Technology

[0002] With the development of tunnel boring machine (TBM) construction technology, "in-tunnel shell disposal and dismantling" is becoming increasingly common in TBM construction. During this process, the removal of the propulsion hydraulic cylinders is a crucial step. Existing technologies often employ methods such as CN111775099A and CN105108468B for dismantling propulsion hydraulic cylinders. However, the current method of dismantling these cylinders using a translational pulling motion results in cumbersome operations and low efficiency. CN119244256A discloses the use of a prefabricated load-bearing structure for installing propulsion hydraulic cylinders, eliminating the need for translational pulling. However, this method still suffers from a lack of corresponding dismantling equipment and methods, leading to long dismantling periods, complex procedures, and cumbersome operations. This invention provides a dismantling and transportation device for prefabricated propulsion hydraulic cylinders to solve these problems. Utility Model Content

[0003] This utility model provides a dismantling and transportation device for assembled propulsion hydraulic cylinders. The dismantling and transportation device is used to dismantle the propulsion hydraulic cylinders, which greatly improves the dismantling efficiency of the propulsion hydraulic cylinders.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is:

[0005] A disassembly and transportation device for assembled propulsion hydraulic cylinders is provided for disassembling and transporting assembled propulsion hydraulic cylinders. The device includes a transport vehicle, a disassembly and assembly structure, and a placement structure. The transport vehicle is set on a track and runs along the track. The placement structure is set on the transport vehicle for placing the propulsion hydraulic cylinder. The disassembly and assembly structure is set on the placement structure and is used for picking up, placing, disassembling, and assembling the propulsion hydraulic cylinder.

[0006] The disassembly and assembly structure includes a disassembly and assembly moving rod and a disassembly and assembly component. The disassembly and assembly moving rod is disposed on the placement structure. The disassembly and assembly moving rod rotates around an axis and moves back and forth on the placement structure along its axis. The disassembly and assembly component is disposed on the disassembly and assembly moving rod.

[0007] Furthermore, the disassembly and assembly assembly includes a first disassembly and assembly arm, a second disassembly and assembly arm, a third disassembly and assembly arm, and a disassembly and assembly clamp. The inner end of the first disassembly and assembly arm is fixedly connected to the disassembly and assembly moving rod. The inner end of the second disassembly and assembly arm is movably connected to the outer end of the first disassembly and assembly arm. The inner end of the third disassembly and assembly arm is movably connected to the outer end of the second disassembly and assembly arm. The disassembly and assembly clamp is movably connected to the outer end of the third disassembly and assembly arm.

[0008] Furthermore, the disassembly and assembly components are arranged in groups at the front of the disassembly and assembly moving rod, with two disassembly and assembly components in each group moving synchronously.

[0009] Furthermore, the placement structure includes a group of placement components, which are mounted on a transport vehicle. Each placement component includes a placement rack and a mounting rack, which are arranged in pairs. The two placement racks are arranged symmetrically from left to right. The mounting rack is located at the top of the placement rack, and the disassembly and assembly moving rod is located on the mounting rack.

[0010] Furthermore, the placement rack is provided with placement slots at intervals.

[0011] Preferably, the disassembly / assembly clamp is a mechanical gripper.

[0012] The beneficial effects of this utility model are as follows:

[0013] When using a dismantling and transportation device to dismantle the propulsion hydraulic cylinder, there is no need to use the translation and pulling method. With the assembled load-bearing structure of the propulsion hydraulic cylinder, the propulsion hydraulic cylinder can be quickly dismantled, which greatly improves the dismantling efficiency and construction safety.

[0014] During dismantling, the lower propulsion hydraulic cylinder is first used to stabilize the dismantling and transportation device to ensure the overall stability. After the upper propulsion hydraulic cylinder is removed, the upper propulsion hydraulic cylinder is used to stabilize the dismantling and transportation device to ensure its stability without affecting the removal of the lower propulsion hydraulic cylinder. This effectively reduces the structural complexity of the dismantling and transportation device and greatly improves the convenience and safety of construction. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figure 1 , 2 As shown, a dismantling and transporting device for assembled propulsion hydraulic cylinders is used to disassemble, assemble, and transport propulsion hydraulic cylinders that are assembled and installed on a tunnel boring machine. The dismantling and transporting device includes a transport vehicle 1, a dismantling and assembly structure 2, and a placement structure 3. The transport vehicle 1 is set on a track and runs along the track to transfer the transport vehicle 1 to the construction site. The placement structure 3 is set on the transport vehicle 1 and is used to place the propulsion hydraulic cylinder. The dismantling and assembly structure 2 is set on the placement structure 3 and is used to take the propulsion hydraulic cylinder from the placement structure 3 and to disassemble and assemble the propulsion hydraulic cylinder from the abandoned tunnel boring machine.

[0024] like Figure 4 , 5As shown, the construction principle of this utility model is as follows: The dismantling and transporting device is moved to the construction site by the transport vehicle 1, and the dismantling and assembly of the propulsion hydraulic cylinder is realized by the forward and backward movement of the transport vehicle 1. The placement structure 3 is set on the transport vehicle 1 to store the dismantled propulsion hydraulic cylinder, and also serves as the installation base for the dismantling and assembly structure 2. The dismantling and assembly structure 2 includes a dismantling and assembly moving rod 21 and a dismantling and assembly component 22. The dismantling and assembly moving rod 21 is movably set on the placement structure 3 and can rotate around its axis and move forward and backward along the axis. The dismantling and assembly moving rod 21 makes room by moving forward and backward along the axis. The dismantling and assembly moving rod 21 controls the orientation of the dismantling and assembly component 22 by rotating around its axis, so as to facilitate the alignment of the dismantling and assembly component 22 with the propulsion hydraulic cylinder. The dismantling and assembly component 22 is fixedly set on the dismantling and assembly moving rod 21 and moves together with the dismantling and assembly moving rod 21 to realize the dismantling of the propulsion hydraulic cylinder. When disassembling the propulsion hydraulic cylinders, first, the propulsion hydraulic cylinders fixed at the bottom of the tunnel boring machine (TBM) are aligned with the placement structure 3. The propulsion hydraulic cylinders are used to restrict the placement structure 3, thereby keeping the entire disassembly and transportation device stable. At this time, the entire disassembly and transportation device is within the range of the propulsion hydraulic cylinders of the TBM. Then, the disassembly and assembly components 22 are used to remove the propulsion hydraulic cylinders on the top of the TBM. The removed propulsion hydraulic cylinders are placed on the placement structure 3 as counterweights. After the propulsion hydraulic cylinders on the top of the TBM are removed, the disassembly and transportation device is moved backward to remove it from the range of the propulsion hydraulic cylinders of the TBM. At this time, the removed propulsion hydraulic cylinders, as counterweights, can maintain the stability of the disassembly and transportation device. Then, the disassembly and assembly moving rod 21 is controlled to move back and forth, driving the disassembly and assembly components 22 on it to move, so that the disassembly and assembly components 22 are still aligned with the propulsion hydraulic cylinders on the TBM, thereby enabling the disassembly and assembly of the propulsion hydraulic cylinders at the bottom of the TBM, thus achieving the disassembly and assembly of all propulsion hydraulic cylinders on the TBM.

[0025] like Figure 1 , 2 As shown, the disassembly and assembly structure 2 includes a disassembly and assembly moving rod 21 and a disassembly and assembly component 22. The disassembly and assembly moving rod 21 is movably mounted on the placement structure 3. The disassembly and assembly moving rod 21 can rotate around its axis and move back and forth on the placement structure 3 along its axis. The disassembly and assembly moving rod 21 serves as the mounting base for the disassembly and assembly component 22 and controls the alignment of the disassembly and assembly component 22 with the propulsion hydraulic cylinder. The disassembly and assembly component 22 is mounted on the disassembly and assembly moving rod 21 and is used for disassembling, assembling, and placing / removing the propulsion hydraulic cylinder.

[0026] like Figure 1 , 2As shown, the disassembly and assembly components 22 are further arranged in groups at the front of the disassembly and assembly moving rod 21, with two components 22 in each group. The two components 22 operate synchronously to disassemble and assemble the propulsion hydraulic cylinder. During the disassembly and assembly operation, the two components 22 are respectively clamped at the front and rear ends of the propulsion hydraulic cylinder to support it and maintain its stability. Then, the load-bearing structure of the propulsion hydraulic cylinder is removed, allowing the propulsion hydraulic cylinder to fall onto the disassembly and assembly components 22. The disassembly and assembly components 22 then move to transfer the propulsion hydraulic cylinder into the placement structure 3.

[0027] like Figure 2 , 3 As shown, the disassembly and assembly assembly 22 further includes a first disassembly and assembly arm 221, a second disassembly and assembly arm 222, a third disassembly and assembly arm 223, and a disassembly and assembly clamp 224. The inner end of the first disassembly and assembly arm 221 is fixedly connected to the disassembly and assembly moving rod 21. The inner end of the second disassembly and assembly arm 222 is movably connected to the outer end of the first disassembly and assembly arm 221, so that the second disassembly and assembly arm 222 and the first disassembly and assembly arm 221 can rotate relative to each other. The inner end of the third disassembly and assembly arm 223 is movably connected to the outer end of the second disassembly and assembly arm 222, so that the second disassembly and assembly arm 222 and the third disassembly and assembly arm 223 can rotate relative to each other. The first disassembly and assembly arm 221 and the second disassembly and assembly arm 222, and the second disassembly and assembly arm 222 and the third disassembly and assembly arm 223 are all movably connected. The angle and position can be adjusted through relative movement to realize the transfer of the propulsion hydraulic cylinder. The disassembly and assembly clamp 224 is movably connected to the outer end of the third disassembly and assembly arm 223 and is used to clamp and fix the propulsion hydraulic cylinder.

[0028] like Figure 1 , 2 As shown, the placement structure 3 further includes a group of placement components arranged at intervals on the transport vehicle 1. Each placement component includes a placement rack 31 and a mounting rack 32. The placement racks 31 and mounting racks 32 in the placement component are arranged in pairs. Each placement component includes two placement racks 31 and two mounting racks 32. The placement racks 31 and mounting racks 32 are arranged in a one-to-one correspondence. The two placement racks 31 are symmetrically arranged on the transport vehicle 1. The mounting racks 32 are correspondingly arranged at the top of the placement racks 31. The tops of the two mounting racks 32 are connected to each other to realize the installation of the disassembly and assembly moving rod 21 and to support the disassembly and assembly moving rod 21. The disassembly and assembly moving rod 21 is movably arranged at the top of the mounting rack 32.

[0029] Furthermore, the placement frame 31 is provided with placement slots at intervals for placing propulsion hydraulic cylinders. Some of the placement slots on the placement frame 31 correspond to the propulsion hydraulic cylinders at the bottom of the tunnel boring machine. When the dismantling and transportation device moves back and forth, the propulsion hydraulic cylinders at the bottom of the tunnel boring machine can align with the placement slots and engage with them, thereby restricting and stabilizing the entire dismantling and transportation device.

[0030] Furthermore, the disassembly and assembly clamp 224 is a mechanical claw, and the opening and closing of the disassembly and assembly clamp 224 is achieved through control.

[0031] like Figure 4 , 5 As shown, a disassembly and transportation device for assembled propulsion hydraulic cylinders includes the following steps:

[0032] S1, component prefabrication: fabricate disassembly structure 2 and placement structure 3 according to the drawings, and pre-install disassembly structure 2 and placement structure 3 on transport vehicle 1 to complete the installation of disassembly and transportation device and control the disassembly and transportation device to standby state.

[0033] S2, Lowering the device into the shaft: The dismantling and transportation device, which is in standby mode, is hoisted into the shaft and placed on the travel track. After the components on the outside of the abandoned shell shield machine are dismantled, the dismantling and transportation device is moved to the position below the propulsion hydraulic cylinder of the abandoned shell shield machine.

[0034] S3, Device in Position: The dismantling and transporting device continues to move, aligning the propulsion hydraulic cylinder at the bottom of the abandoned shell shield machine with the placement structure 3 and locking it into the placement slot of the placement structure 3. The propulsion hydraulic cylinder located in the placement structure 3 is used to maintain the stability of the entire dismantling and transporting device. Then, the dismantling and assembly moving rod 21 is controlled to translate and rotate around the axis on the placement structure 3, adjusting the position and orientation of the dismantling and assembly component 22 so that the dismantling and assembly component 22 is aligned with the propulsion hydraulic cylinder located on the upper side.

[0035] S4, upper propulsion hydraulic cylinder removal: control the disassembly and assembly component 22 to move so that it is locked on the propulsion hydraulic cylinder to be removed, keep the state of the disassembly and assembly component 22 stable and locked, and then remove the connection between the propulsion hydraulic cylinder to be removed and the shield machine host and the movable part of the bearing partition, so that the propulsion hydraulic cylinder falls on the disassembly and assembly component 22.

[0036] S5, Upper propulsion hydraulic cylinder placement: Control the disassembly and assembly component 22 to place the disassembled propulsion hydraulic cylinder on the placement structure 3;

[0037] S6, Repeated Operation: Following the operations of S4-S5, remove all the propulsion hydraulic cylinders on the upper part of the shield tunneling machine and place them on the placement structure 3. When removing the propulsion hydraulic cylinders, remove them in a top-to-bottom and left-to-right symmetrical order. When placing the propulsion hydraulic cylinders, place them in a bottom-to-top and left-to-right symmetrical order, so that the removed propulsion hydraulic cylinders serve as counterweights for the dismantling and transportation device, maintaining the stability of the dismantling and transportation device in subsequent dismantling operations.

[0038] S7, Device movement: Control the dismantling and transportation device to move backward, so that the propulsion hydraulic cylinder at the bottom of the abandoned shield machine is dislodged from the placement structure 3, so that the dismantling and transportation device moves to outside the range of the propulsion hydraulic cylinder. At this time, the entire dismantling and transportation device is stabilized by the dismantled propulsion hydraulic cylinder, and then the lower propulsion hydraulic cylinder is dismantled and placed.

[0039] S8, Removal and Placement of Lower Propulsion Hydraulic Cylinder: Control the disassembly and assembly moving rod 21 to move forward on the placement structure 3, so that the disassembly and assembly component 22 is aligned with the propulsion hydraulic cylinder located on the lower side. Then control the disassembly and assembly moving rod 21 to rotate on the placement structure 3, adjust the orientation of the disassembly and assembly component 22, so that the disassembly and assembly component 22 is aligned with the propulsion hydraulic cylinder located on the lower side. Remove the propulsion hydraulic cylinder at the bottom of the shield tunneling machine according to the operation in S4. Control the disassembly and assembly moving rod 21 to move backward, so that the disassembly and assembly component 22 and the propulsion hydraulic cylinder on it move together, so that the disassembly and assembly component 22 and the propulsion hydraulic cylinder on it are aligned with the placement structure 3. Then place the removed propulsion hydraulic cylinder on the placement structure 3 according to the operation in S5.

[0040] S9, Repeat the operation: Following the operation in S8, remove all the propulsion hydraulic cylinders at the bottom of the abandoned shield tunneling machine and place them on the placement structure 3;

[0041] S10, Equipment hoisting out: The dismantling and transportation device is moved to the wellhead, and the propulsion hydraulic cylinder and the dismantling and transportation device are hoisted out through the working well to complete the dismantling of the propulsion hydraulic cylinder.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
