Description

Technical Field

[0001] The utility model relates to the technical field of rack rails, in particular to a rack rail fixing assembly of a rack rail railway. Background Art

[0002] The difference between a cog railway and a general rail railway is that a cog railway usually adds a rack track (also called a rack rail) in the middle of a general railway track, and the bogie of the corresponding running vehicle is equipped with a gear device that meshes with the rack track to supplement the wheel-rail adhesion when the vehicle climbs a slope or use the rack rail meshing force instead of adhesion to achieve the purpose of driving the rail vehicle to climb the slope; in the construction of a cog railway, the installation of its core component, the rack rail, is particularly important.

[0003] The rack rail is composed of a large number of prefabricated racks. In order to ensure the quality of the assembly of all racks after installation and to meet the requirements of use in harsh working conditions, it is necessary to conduct strict final inspection on parameters such as longitudinal pitch (the distance between two adjacent racks), transverse pitch (the distance between the guide rail and the rack) and vertical elevation difference. If the existing tools are used for inspection, not only the cycle is long and the workload is large, but also the relevant parameters are not intuitive, and manual observation and judgment are required, resulting in large errors, which invisibly increases the cost and brings great difficulties to the final inspection of the product.

[0004] Due to the manufacturing size requirements of the rack, the longitudinal pitch and other position parameters of the two adjacent racks cannot be accurately and quickly detected during installation, and the construction efficiency is low. For this reason, there is a public technology on the market that proposes an adjacent rack installation and adjustment device for a rack railway, including a frame slidably connected to the steel rails on both sides and a working module located below the frame, the working module including a meshing rack, a base and a guide rail, the guide rail is slidably connected to the frame up and down, the guide rail is fixedly connected to the base, the base is detachably connected to the meshing rack, the meshing rack is used to mesh with the rack to be installed, and the guide rail is used to identify the relative height between the meshing rack and the frame; this technology can quickly locate longitudinally, and assist in adjusting the longitudinal pitch between the two adjacent racks, so that the two adjacent racks can be installed flatly, the installation position height meets the driving requirements, the construction is fast and efficient, the positioning is accurate, and it is conducive to improving the construction efficiency;

[0005] However, although the tool used in the above technology can quickly locate the longitudinal pitch between two adjacent racks, the fixed position on the base is processed in advance, and the rack is fixed to the base through a fixing seat and screws. When the fixed position on the base cannot be aligned with the screw hole of the rack after the longitudinal pitch is accurately found through the above technology, installation cannot be achieved, and the existing fixing seat cannot adjust the rack height, so it is necessary to make further improvements.
