Description

Technical Field

[0001] The present application relates to the technical field of shield machine disassembly and assembly, and in particular to a large-diameter main drive transport tooling in a tunnel. Background Art

[0002] The large-diameter shield machine itself is large in size and needs to be dismantled after being taken out of the tunnel one by one and then hoisted separately. In particular, the main drive weight of the large-diameter machine reaches 250 tons, which makes it more difficult to take the large-diameter shield machine out of the tunnel and dismantle it as a whole.

[0003] During the dismantling process of the large shield machine, the main drive of the large shield machine is dismantled in the hole. Since the dismantling process is carried out inside the shield machine shell, the structural size of the shell is a circular thickness of 50mm, and the stress state cannot meet the conventional dismantling requirements, so the dismantling needs to be carried out with the help of other heavy equipment. After the shield machine is dismantled, the main part (including the front and middle shield blocks, telescopic rings, main drive, cutter head and other components) needs to be loaded before it can be transported out of the tunnel. The channel elevation of the transport vehicle is the top elevation of the box culvert. If the reversal of all components is carried out by lifting, the process is repeated and the safety is low, which is not convenient for disassembling the main drive and then transporting it out.

[0007] By adopting the above technical solution, when transporting the main drive, the lifting member is installed on the transport frame, and the disassembled main drive components are sequentially connected to the end of the lifting member away from the transport frame to drive the moving member, and the moving member drives the transport frame together with the main drive to move, so as to facilitate the transportation of the disassembled main drive components. When installing the lifting member, the fixed end of the lifting member is fixed to the lifting ear, so as to facilitate the installation of the lifting member on the transport frame. Multiple running wheels can be driven to move by themselves, so that the transport frame has multiple power sources to move during movement, so that when the multiple running wheels are moving, the stability of the transport frame during the movement can also be improved.

[0010] Optionally, the transport frame is a truss formed by splicing H frames.

[0011] By adopting the above technical solution, the H frame increases the fulcrum and lateral strength of the transport frame, which can improve the stability of the transport frame.

[0012] Optionally, the transport rack is in an “n” shape as a whole.

[0013] By adopting the above technical scheme, the "n"-shaped transport frame is convenient for entering the shield machine casing, and the placement space of the transport frame in the shield machine casing is increased. The placement space is convenient for placing the disassembled main drive components in the placement frame, and it is convenient for placing the disassembled main drive components in the "n"-shaped transport frame for transportation out.

[0014] Optionally, a transport vehicle is provided at one end of the transport track away from the main drive.

[0016] Optionally, reinforcing ribs are provided between the cross beam and the columns.

[0017] By adopting the above technical solution, the reinforcing ribs are used to improve the connection strength between the cross beams and the columns, thereby increasing the overall stability of the transport rack.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

When the main drive component is disassembled, the transport frame is located above the main drive component, and the lifting device is used to lift the main drive component, and the moving device is driven. The moving device drives the transport frame and the main drive component to move along the transport track to the outside of the shield machine casing, so as to facilitate the transport of the disassembled main drive;

[0020] 2. By setting up a transport vehicle, when the main drive component is moved out of the shield machine casing through the transport frame and close to the transport vehicle, the main drive component is placed on the transport vehicle using a lifting device, the connection between the lifting device and the main drive component is released, and the main drive component is transported out using the transport vehicle, so that the transport vehicle can easily transport the main drive component.

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] The present application embodiment discloses a large diameter main drive transport tooling in a tunnel. Figure 1 , Figure 2 and Figure 3A large-diameter main drive transport tooling in a tunnel includes a transport frame 1 and a transport track 2. The transport frame 1 is arranged above the transport track 2. The transport frame 1 includes a crossbeam 11 and columns 12 arranged at both ends of the crossbeam 11. The transport frame 1 is a truss formed by splicing H frames. The transport frame 1 is welded as a whole, and the transport frame 1 is arranged in an "n" shape as a whole, so that the transport frame 1 can be placed in the shield machine casing, and at the same time, the placement space of the transport frame 1 in the shield machine casing can be increased, and the disassembled main drive components can be easily covered, so that the main drive components are completely located under the transport frame 1.

[0028] Reference Figure 1 , Figure 2 and Figure 3 Four lifting ears 13 are welded on the cross beam 11. The four lifting ears 13 are evenly distributed below the cross beam 11. The lifting ears 13 are used to install lifting parts. The lifting parts are not shown in the figure. The lifting parts are used to lift the main drive. The lifting parts are cranes, hand hoists or hoists. In this embodiment, it is a hoist. When installing the lifting parts, the lifting parts can be installed on the lifting ears using bow-shaped shackles. A reinforcing rib 14 is welded between the cross beam 11 and the column 12. The reinforcing rib 14 is a triangular plate. The two right-angled sides of the reinforcing rib 14 are welded to the side walls of the cross beam 11 and the column 12 respectively.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A moving part 3 is provided at one end of the transport frame 1 close to the transport track 2. The moving part 3 is used to drive the transport frame 1 to move along the transport track 2. The moving part 3 is a plurality of walking wheels. In this embodiment, four walking wheels are provided. The walking wheels can provide a walking power source for the transport frame 1 to drive the transport frame 1 to move along the transport track 2.

[0030] Reference Figure 1 , Figure 2 and Figure 3 In order to facilitate the installation of the running wheels, the bottom of the columns 12 on the left and right sides of the transport frame 1 are welded with connecting rods 15, which are steel sections. Each connecting rod 15 is provided with two running wheels, and the positions of the running wheels on the connecting rods 15 on the left and right sides correspond to each other, so as to improve the stability of the transport frame 1 during the travel.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The transport track 2 is a "c"-shaped track with its opening facing upward. The opening of the transport track 2 is at the same distance from the wheel width of the traveling wheel. A travel gap is left between the inner wall of the transport track 2 and the side wall of the traveling wheel. On the one hand, it is convenient for the transportation track 2 to place the traveling wheel, and on the other hand, it is convenient for the traveling wheel to move forward along the transport track 2. In order to improve the fit between the traveling wheel and the transport track 2, the traveling wheel can also be an "H"-shaped wheel, and the transport track 2 is a "convex"-shaped track that matches the "H"-shaped wheel.
