Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunneling machine disassembly in the hole, in particular to a disassembly method of a hole-in sliding shoe type rear matching trailer. BACKGROUND

[0002] With the acceleration of the modernization process in China, tunneling machines have been increasingly widely used in mountain tunnel construction, gradually replacing the original manual blasting construction method, and at the same time, various tunneling machine disassembly methods have appeared.

[0003] The tunneling machine used in mountain tunnels is different from the earth pressure balance shield tunneling machine used in urban subways in terms of disassembly conditions. The site is in a remote mountainous area, the access road is narrow and uneven, and large equipment is difficult to access. The tunnel is deeply buried, and underground reception is usually performed. If the blind hole tunnel does not have the receiving conditions, the disassembly difficulty is even greater.

[0004] For hole-in sliding shoe type rear matching disassembly, the conventional disassembly method is to build an enlarged chamber, install electric hoists and other lifting beam tools, use the tools to disassemble and remove the rear matching, and then use a flat car to transport it out of the hole. Not only is the cost high, but the efficiency is low, and the safety risk is also high.

[0005] Patent No. CN114933233A discloses a TBM hole-in reverse disassembly method without an enlarged chamber. The rear matching area is disassembled by using a vault sliding rail for auxiliary disassembly. Two sliding rails are longitudinally arranged on the tunnel arch at the rear matching position. The sliding rails are anchored on the wall by retracting the anchor rod. The sliding rails are equipped with lifting hoists. The rear matching trailer is disassembled from the rear to the front, one section at a time, and transported out of the hole using a rail car. Before disassembly begins, the connections between adjacent trailers are disconnected, the rail car is used to pull the trailer to be disassembled under the sliding rail, and the lifting hoist on the sliding rail is used for disassembly and lifting operations. The above-mentioned patent still disassembles the rear matching in the tunnel, still needs to use lifting beam tools, flat cars and other tools, and the disassembly method is inefficient and has high safety risks. SUMMARY

[0006] The present application proposes a hole-in sliding shoe type rear matching trailer disassembly method, which solves the problem of the need to expand the enlarged chamber, the need for lifting beam tools, and the need for multiple operations in the tunnel during the disassembly of the rear matching in the prior art.

[0007] The technical solution of the present application is as follows:

[0008] The hole-in sliding shoe type rear matching trailer disassembly method comprises the following steps:

[0009] S1, disassemble the connecting structure between adjacent rear matching trailers; facilitate the removal of the rear matching trailers one by one from the tunnel for disassembly, and improve the disassembly efficiency.

[0010] S2, laying a tractor track in the tunnel, and extending the tractor track to the rear of the rear matching trailer; the rear matching trailer can be moved to the tractor track by a short distance, facilitating the rapid removal of the rear matching trailer.

[0011] S3, abutting the slope tool and the tractor track; the slope tool guides the rear matching trailer, and the rear matching trailer can be moved to the tractor track without using hoisting tools.

[0012] S4, installing the manufactured slide plate tool at the lower part of the slide shoe of the rear matching trailer; the slide plate tool ensures the stable connection between the rear matching trailer and the tractor track, and ensures the safety of the removal process of the rear matching trailer.

[0013] S5, starting the tractor to move to the rear of the rear matching trailer, and connecting the tractor and the rear matching trailer by using a connecting piece; the tractor moves into the tunnel, and the tractor drives the rear matching trailer to move through a pull rod.

[0014] S6, starting the tractor to pull the rear matching trailer to the slope tool, and moving the rear matching trailer to the tractor track through the slope tool, and then pulling the rear matching trailer to move to the outside of the tunnel along the tractor track by the tractor; the tractor moves to the outside of the tunnel, and the rear matching trailer is pulled out of the tunnel by the pull rod.

[0015] S7, sliding the slide plate tool with the tractor track, and removing the slope tool and the slide plate tool after one rear matching trailer is pulled out of the tunnel; after the rear matching trailer is removed from the tunnel, the rear matching trailer is disassembled outside the tunnel, the operation space is large, the workers are facilitated to disassemble, and the disassembly efficiency of the rear matching trailer is improved.

[0016] S8, extending the tractor track to the next rear matching trailer, reinstalling the slope tool and the slide plate tool, and repeating the operations of steps S5, S6 and S7 until all the rear matching trailers are transported to the outside of the tunnel, and the disassembly of the rear matching trailers is completed.

[0017] The slope tool comprises a support, and an obliquely arranged slide rail is fixed on the support; the upper end of the slide rail corresponds to the end position of the tractor track, and the slide rail is in sliding cooperation with the slide plate tool. The rear matching trailer is slid upward to the tractor track through the slide rail, so that the rear matching trailer moves to the tractor track without using hoisting tools.

[0018] The inclination angle of the slide rail ranges from 1° to 15°. The smaller inclination angle of the slide rail can enable the tractor to pull the rear matching trailer onto the slope tool with smaller force.

[0019] The slide plate tooling includes a slide plate body, the bottom of the slide plate body is provided with a downwardly open slide groove, the slide groove is in sliding fit with the tractor track, and the top of the slide plate body is provided with a hook connected with the slide shoe of the rear matched trailer.

[0020] The two ends of the slide groove are provided with upwardly inclined inclined plates, and the lower surfaces of the inclined plates are in arc transition connection with the groove bottom surfaces of the slide groove. The inclined plates guide the slide plate tooling to be more easily placed on the slope tooling.

[0021] The inclination angle of the inclined plate is equal to the inclination angle of the slide rail. When the slide plate tooling just contacts the slope tooling, the inclined plate can better contact the slide rail, thereby reducing the abrasion of the slide plate tooling.

[0022] The two ends of the slide groove are provided with flared structures integrally connected with the side walls of the slide groove. The flared structures have a guiding effect, so that the slide plate tooling can be quickly connected with the slope tooling, and the problem of mispositioning of the rear matched trailer with the slide rail and the tractor track is effectively avoided.

[0023] In S4, a plurality of slide plate toolings are installed on each rear matched trailer. The number of slide plate toolings is four, and the plurality of slide plate toolings jointly provide support for the rear matched trailer.

[0024] In S1, the electrical, hydraulic and fluid parts between the rear matched trailers are removed, and the connecting pins and connecting pull plates between the rear matched trailers are removed section by section. The adjacent rear matched trailers are separated, so that the rear matched trailers can be transported out of the tunnel one by one.

[0025] In S6, before the tractor is started, the equipment on the rear matched trailer is temporarily fixed. This avoids the equipment from falling off during the removal of the rear matched trailer, and ensures the safety of the removal process.

[0026] The present application has the following beneficial effects: the rear matched trailer is split into independent individuals in the tunnel, then the rear matched trailer is pulled onto the tractor track by the tractor, then the tractor pulls the rear matched trailer along the tractor track to the outside of the tunnel, and the rear matched trailer and the equipment on the trailer are disassembled outside the tunnel, which greatly improves the disassembly efficiency of the rear matched trailer, reduces the operation space required during disassembly, avoids the process of building an enlarged chamber in the tunnel, reduces the process, and improves the disassembly efficiency of the rear matched trailer.

[0027] When the tractor pulls the trailer, the trailer is lifted by a ramp tool and moved onto the tractor track. The sliding plate tool works in conjunction with the tractor track to limit and guide the trailer, allowing it to move out of the tunnel along the tractor track. This avoids the need to set up lifting beam equipment inside the tunnel and eliminates the need for a flatbed truck, greatly saving operation time and ensuring safety. Attached Figure Description
