Description

Technical Field

[0001] The utility model relates to the technical field of contact rail installation equipment, and more specifically, to a contact rail joint installation auxiliary clamp. Background Art

[0002] During the operation of rail transit with the power supply of the lower current-collecting contact rail, the contact rail intermediate joint plays a core role with the contact rail, the end elbow and the expansion joint. If the intermediate joint is installed incorrectly, the traction power supply system will not be able to supply power to the electric passenger car normally, endangering the daily operation of rail transit. At present, during the construction process, the tools used to install the contact rail intermediate joint are mostly homemade tools (jacks and guide chains), which are used to lift the contact rail to the target height, and then adjusted by manpower so that the height difference of the lower surface at the two adjacent rail end joints does not exceed 0.1mm, the left and right spacing is less than 2mm, and it must be polished smooth. The intermediate joint is installed within the corresponding error range. This installation method has the following main disadvantages:

[0003] (1) There are many contact rail intermediate joints to be installed, and the operation range is wide. Construction workers need to carry equipment and materials back and forth, which takes a long time to commute. The installation of the original equipment takes a long time and is inefficient, which easily leads to fatigue of workers and is time-consuming and labor-intensive.

[0004] (2) The original equipment required the installer to perform multiple manual precision adjustments, which resulted in many operations, large errors, and low installation accuracy;

[0005] (3) The original equipment required only 4 people to install the equipment, and the installation period of the contact rail intermediate joint was long, which brought great pressure on the company's expenses;

[0006] (4) The outdated installation method not only reduces the installation accuracy, but also makes it impossible for the professional technical team to effectively control the execution of the installation work of the front-line personnel, which brings difficulties to the company's continuous promotion of the standardization management process.
