Problems solved by technology

At present, the positioning measurement method is generally used, which is equivalent to establishing a plane coordinate system in the track groove, positioning and measuring the longitudinal and lateral positions of each pre-embedded screw, and then positioning, drilling, and drilling on the steel backing plate according to the measurement results. The steel backing plate for the hole is installed at the corresponding position on site. However, the installation effect of the processed steel backing plate is still not ideal, mainly because the accidental errors of on-site measurement and lofting positioning are difficult to control

Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The method for installing the track steel backing plate using the value-shifting technology includes the following specific steps:

[0029] a. Clean the track groove, and straighten the embedded bolts through the straightening device, so that the inclination between the embedded bolts and the horizontal plane is not more than 1 degree, and prepare for the subsequent installation of the steel backing plate;

[0030] b. Erection of the center line of the track groove;

[0031] c. Use a 3-4mm thick transparent hard plastic plate to make the grafting plate, preferably a 3mm thick transparent hard plastic plate. The length of the transplanting plate is consistent with the length of a single track steel backing plate, and the width is the same as the width of the track steel backing plate consistent;

[0032] d. Lay the transplant plate on ...

Abstract

The invention discloses a method for installing a rail steel backing plate by a transplanting technique. The method comprises the following steps of a, checking the verticality of an embedded bolt, and aligning; b, erecting a centerline of a rail groove; c, manufacturing a transplanting plate; d, putting the transplanting plate at the top part of the embedded bolt, adjusting the centerline of thetransplanting plate, and aligning with the centerline of the rail groove along the vertical direction; e, marking the center point of the embedded bolt at the front surface of the transplanting plate;f, transferring the transplanting plate with the marked centerline of the embedded bolt to a rail steel backing plate, mutually overlapping, aligning and fixing; g, drilling a hole in the marked center point on the transplanting plate, and forming drilling trace on the rail steel backing plate; h, detaching the transplanting plate, and drilling a hole in the rail steel backing plate with the drilling trace; I, installing the drilled rail steel backing plate to the embedded bolt, and repeating the steps, until the installation of all rail steel backing plates of the whole rail is completed. The method has the advantages that the steel backing plates can be accurately and correctly installed to the embedded bolts, and the working efficiency is obviously improved.

Description

technical field [0001] The invention relates to a method for installing a track steel backing plate by using the value-shifting technology. Background technique [0002] The flexible track fixing technology entered the Chinese port industry in the 1980s and completely changed the level of wharf track technology. The continuous steel backing plate is the most important load-bearing structural part in the system. [0003] Steel backing plate installation is a major process in the crane track installation system. Due to deviations in the construction and installation of embedded bolts, especially in track reconstruction projects, affected by the dense steel bars of the track beams, the position deviation of planted embedded bolts is very large. If according to The design position drills holes on the steel backing plate, even if the hole diameter is enlarged by 20mm, it cannot be installed at all. At present, the positioning measurement method is generally used, which is equiva...
