Turnout rapid construction apparatus and method during existing station transformation

Abstract

The invention discloses a turnout rapid construction apparatus and method during existing station transformation, and relates to the technical field of existing station turnout construction. The apparatus mainly comprises a pre-paving platform, a lifting device, a walking device and a traction device. The construction method mainly comprises the following steps: the pre-paving platform is erected,a turnout is pre-paved, debugged and accepted on the platform, and the lifting device, the walking device and a traction device are installed; a construction area is blocked, the train operation is stopped, and the construction time is determined; the turnout is transversely moved to cross a rail; the turnout is longitudinally moved to the outer side of a turnout laying position; an existing lineat the laying position is removed from the point; the turnout is placed in place through transverse movement, and the walking device is dismantled; the elevation and direction of the turnout are adjusted; the turnout is finely adjusted; and electric service debugging and work acceptance are carried out, and a blocking line is opened after qualification. Various advanced processes of turnout pointconstruction are integrated, specialized organization is facilitated, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of turnout construction at existing stations, in particular to a rapid construction device and method for turnouts during reconstruction of existing stations. Background technique [0002] With the improvement of railway design standards, it is necessary to renovate and expand existing stations, dismantle, replace, insert and lay turnouts, and pre-lay turnouts without affecting the operation of business lines. The professional term) removes the existing line, and inserts a new turnout by moving across the track or longitudinally across the switch area, and moving it into place. [0003] Concretely, there are following problems in existing turnout construction: [0004] First, due to the constraints of railway design rules, the land boundary is becoming more and more limited, and it is difficult to meet the pre-paved site of the turnout. After the turnout is pre-paved, it must be basically consistent with th...

Problems solved by technology

[0004] First, due to the constraints of railway design rules, the land boundary is becoming more and more limited, and it is difficult to meet the pre-paved site of the turnout. After the turnout is pre-paved, it must be basically consistent with the basic line elevation to ensure that the turnout can move quickly after pointing out, which leads to the need to build a pre-paved platform. ;

[0005] The second is that the distance between the existing electrified catenary poles is insufficient, and the turnouts laid nearby cannot be laterally moved into place;

[0006] The third is that the turnout cannot be pre-paved in alignment, and the site that meets the pre-paving conditions of the turnout is far away from the laying position of the turnout. The turnout needs to be moved across the track and moved vertically over a long distance to pass the turnout area or curve before it can be aligned;

[0007] Fourth, as the speed of the railway increases, the gap between trains decreases and the line becomes more busy, resulting in shorter and shorter time for existing lines;
