Description

Underground translation method of shield trailer Technical Field The application relates to the technical field of shield construction, in particular to a method and a device for underground translation of a shield trailer. Background In the shield assembly process, the underground assembly of the trailer is a key and complex link. Due to the limitation of the shield assembly well structure (such as existence of an intermediate wall) and the obvious height difference between the bottom of the well and the horizontal section of the tunnel, the trailer cannot be directly placed to the designed position through single hoisting. Thus, the trailer must be first towed downhole and then moved multiple times and precisely aligned in a confined, confined downhole space. This process greatly increases the difficulty and complexity of assembly of the shield trailer. The common solution is to lay a sliding rail or a sliding plate and smear lubricating oil, and to provide power by matching with a hydraulic pump station and an oil cylinder. However, the traditional translation method has the remarkable limitations that the degree of freedom of movement is limited (the traditional translation method can only move in one direction or in a small range in two directions), the operation depends on the pushing of the oil cylinder, the process is tedious and time-consuming, and the accurate positioning precision of the trailer after long-distance movement is difficult to ensure. The information disclosed in this background section is only for enhancement of understanding of the background of the disclosure and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art that is well known to a person skilled in the art. Disclosure of Invention In view of at least one of the above technical problems, the present disclosure provides a method for downhole translation of a shield trailer, which mainly solves the technical problems of low downhole assembly efficiency and complicated translation operation of the shield trailer. According to one aspect of the present disclosure, there is provided a method of downhole translation of a shield trailer comprising the steps of: (1) The method comprises the steps of (1) hoisting a height-adjustable module vehicle to the bottom of a shield assembly well, and correspondingly arranging a movable guide rail at the top of the module vehicle as a movable platform; (2) Pre-assembling a shield trailer joint on the ground, and simultaneously moving the mobile platform to a shield trailer hoisting wellhead; (3) The assembled shield trailer is lowered into the well and correspondingly dropped to the movable guide rail; (4) Regulating and controlling the moving platform to the corresponding collineation of the moving guide rail and a trailer track in a well, and controlling the moving platform to move until the moving guide rail is correspondingly contacted with the trailer track after correspondingly regulating the wheel orientation of the moving platform; (5) Moving the shield trailer node to a trailer track; (6) And (5) repeating the steps (2) to (5), and sequentially descending and connecting the shield trailer joints in sequence from front to back. In some embodiments of the disclosure, in the step (1), the moving platform includes at least two module vehicles correspondingly rigidly connected by a connecting piece, and a road base plate correspondingly and fixedly arranged at the top of the module vehicles and used for installing the moving guide rail. In some embodiments of the disclosure, in step (1), the gauge of the moving rail matches the gauge of the shield trailer node. In some embodiments of the disclosure, in the step (2), before lifting, the shield trailer node correspondingly adjusts the moving platform to a highest height of the moving rail within an adjustment range. In some embodiments of the disclosure, in the step (4), a rail support table is provided at the end of the horizontal section rail and the corresponding end of the moving rail extends out of the moving platform for a certain length, and after the extending end of the moving rail is correspondingly moved to a position above the rail support table, the moving platform is adjusted to gradually lower the height of the moving rail until the moving rail contacts with the rail support table. In some embodiments of the disclosure, in step (3), a bottom of the shield trailer node is provided with a first laser source for guiding the shield trailer into alignment with the mobile platform. In some embodiments of the present disclosure, in the step (3), after the shield trailer node is lowered to the moving rail, an anti-slip measure is applied to the shield trailer node. In some embodiments of the disclosure, in step (4), a second laser source is provided at an end position of the trailer track for guiding the mobile platform into alignment with the trailer track.
