Therefore, the problem of efficient pipeline extension in shaft tunnels has become an urgent issue to be addressed. To this end, the technical personnel have provided an efficient pipeline extension device for enlarged-excavation MTMs, as described in this application. Utility Model Content

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Example 1:

[0025] Please see Figure 1-4A high-efficiency pipeline extension device for an expanded shaft tunneling machine includes a pipeline installation platform 1, a pipeline storage bin 2, and a pipeline crane 3. The pipeline installation platform 1 includes a lower platform 13 and an upper platform 14, which are connected as a whole by structural components. The pipeline storage bin 2 is installed on one side of the lower platform 13 and is used to store extension pipes 45. The pipeline crane 3 is installed on the upper platform 14.

[0026] The pipeline installation platform 1 of this utility model is used for personnel to stand on in order to disassemble and install the pipeline 4 of the expanded shaft tunneling machine. The pipeline crane 3 is used to lift out the extension pipe 45 in the pipeline storage bin 2 for installation. Through the above structure, the pipeline extension efficiency of the shaft tunneling machine is improved to meet the requirements of the shaft tunneling machine's tunneling speed.

[0027] In this embodiment, the pipeline crane 3 is a cantilever crane.

[0028] To protect workers on the lower platform 13 and the upper platform 14 from falling, guardrails are installed on the edges of the lower platform 13 and the upper platform 14 respectively.

[0029] See Figure 1 , 4 The pipeline 4 of the expanding shaft tunneling machine includes a shaft wall fixing section 41, a hose section 42, and a platform fixing section 43. In use, the shaft wall fixing section 41 is installed and fixed to the shaft wall, and the platform fixing section 43 is installed and fixed to the pipeline installation platform 1. The extension pipe 45 is used to be installed at the lower end of the shaft wall fixing section 41. One end of the hose section 42 is connected to the extension pipe 45, and the other end is connected to the platform fixing section 43.

[0030] Specifically, the upper end of the well wall fixing section 41 and the extension pipe 45 are connected by an upper connector 44, and the lower end of the extension pipe 45 is connected to the hose section 42 by a lower connector 46. The upper connector 44 and the lower connector 46 are flange-connected structures, or they can be connected by a clamp structure similar to that used for fire water pipes.

[0031] Specifically, the platform fixing section 43 is fixedly installed at the bottom of the upper platform 14.

[0032] Example 2:

[0033] Based on Embodiment 1, to facilitate movement between the lower platform 13 and the upper platform 14, see [reference needed]. Figure 2 A first ladder 12 is installed between the lower platform 13 and the upper platform 14, and a second ladder 11 extending downwards is installed on the lower platform 13.

[0034] In use, the lower platform 13 is installed on the top of the expanded shaft tunneling machine via a metal bracket. The lower end of the second ladder 11 is fixed to the expanded shaft tunneling machine, and the upper end is fixed to the lower platform 13. The lower end of the first ladder 12 is fixed to the lower platform 13, and the upper end is fixed to the upper platform 14.

[0035] Example 3:

[0036] Based on Example 1 or Example 2, see Figure 3 A door 21 is provided on one side of the pipeline storage chamber 2. The door 21 consists of two hinged panels that are hinged to the pipeline storage chamber 2. The two panels of the door 21 can be opened and connected by a latch 22. Multiple lower pipe clamps 23 and / or upper pipe clamps 24 are installed inside the pipeline storage chamber 2. By providing the door 21, the lifting height of the extension pipe 45 is reduced.

[0037] When in use, after unlocking the latch 22, open the compartment door 21. After lifting the extension pipe 45 to a certain height by the pipeline hoist 3, the extension pipe 45 can be moved out of the pipeline storage compartment 2.

[0038] The latch 22 is existing technology. For example, one side of the compartment door 21 is equipped with a fixing tube, and the other side of the compartment door 21 is equipped with a bolt. When the bolt extends, it is inserted into the fixing tube, which can close both compartment doors 21.

[0039] The lower pipe clamp 23 and the upper pipe clamp 24 are existing technologies, such as a clamp structure consisting of two half rings. One half ring is welded and fixed to the pipeline storage chamber 2, and the other half ring is installed and connected to it by bolts. The extension pipe 45 is located between the two half rings.

[0040] The working principle or operation process of this utility model is as follows:

[0041] As the shaft boring machine gradually descends, when the curved extension pipe 42 in pipeline 4 approaches a straightened state, pipeline 4 is closed. The pipeline crane 3 on the pipeline installation platform 1 is rotated above the pipeline storage bin 2. The lock 22 and bin door 21 are manually opened. Workers stand on the lower platform 13 and upper platform 14 of the pipeline installation platform 1, loosening the lower clamp 23 and upper clamp 24 of one of the extension pipes 45. The extension pipe 45 is then lifted out using the pipeline crane 3. The pipeline crane 3 transports the extension pipe 45 to the location of the fixed section 41 on the shaft wall, disassembling the fixed section 41 from the flexible hose section 42. The extension pipe 45 is then connected between the fixed section 41 and the flexible hose section 42 and anchored to the shaft wall.

[0042] During the next installation, the new extension tube 45 will be installed between the previous extension tube 45 and the hose segment 42.
