Double-block type ballastless track bent frame device and adjusting method and construction method thereof

Abstract

The invention discloses a double-block type ballastless track bent frame device and an adjusting method thereof. The double-block type ballastless track bent frame device comprises a track bent framebody, an adjusting piece with one end movably connected to the end of the track bent frame body, and a protection foundation abutting against the side of the track bent frame body. The adjusting pieceis used for fixing double rows of tool rails, the other end of the adjusting piece is movably connected to the protection foundation, the two ends of the adjusting piece can be locked to the track bent frame body and the protection foundation respectively, and transverse width adjustment, height adjustment and horizontal angle adjustment of the track bent frame do not interfere with one another.The invention further discloses a construction method of the double-block type ballastless track bent frame device, the double-block type ballastless track bent frame device has the functions of sleeper mounting and positioning, track coarse adjustment, template mounting and track fine adjustment, the operation procedure can be effectively simplified, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of railway track construction, and in particular relates to a double-block ballastless track bending device, its adjustment method and its construction method. Background technique [0002] The traditional single-girder track bent frame generally has four rectangular tube joists, which not only fully expands the joist spacing, but also increases the construction operation space, which greatly facilitates the construction personnel to carry out steel bar binding, concrete pouring, concrete vibrating, and concrete plastering. In the construction process, the function of the track bent frame is to simulate the formal rail, and accurately lock the position of the double-block sleeper, the long sleeper embedded sleeper and the elastic support block sleeper, so as to ensure the geometric shape of the formal track. The geometry of the track includes: gauge, direction, elevation, level, and bottom slope. The geometric shape ...

Problems solved by technology

[0004] However, with the passage of time, this way of locking a single joist to realize the adjustment of the track geometry has gradually revealed shortcomings such as difficult positioning of the rough laying of the track, repeated fine adjustment construction, and large manual interference. The horizontal and elevation of the tool rail are all linked and will interfere with each other. When one of the parameters is adjusted, other parameters will also change at the same time. It often requires continuous debugging to complete, but it is also very difficult in the end. To ensure the accuracy, for this reason, it is urgent to develop a ballastless track bent frame, which can be used with the rough paving machine to realize the preliminary positioning of the track bent frame rough paving. At the same time, the track direction can be adjusted independently during the track fine adjustment construction , elevation and other parameters, so that the adjustment of multiple fine-tuning parameters does not interfere with each other, greatly improving the efficiency of fine-tuning construction of the rail row
