Problems solved by technology
[0003] During the installation process of the loose-laid nail-linked fasteners, two workers are required to hold the fasteners by hand, and the other two workers pull the left and right elastic strips at the same time to complete the installation of the loose-laid nail-linked fasteners. This process requires four people to complete the fasteners The installation of nail joints is labor-intensive
At the same time, if the installation of the left and right elastic bars is not synchronized or the force of pulling the elastic bars is not uniform, the fasteners will be skewed after installation, which will affect the installation quality

The invention discloses a control device for installing nail-connected fasteners for loose pavement, which includes a connecting device for fixing the installation control device for nail-connected fasteners for loose-pavement and subway nail-connected fasteners for loose-pavement under the rails, and is used for placing subway The bracket of the nail-linked fastener for loose pavement and the limiting part for limiting the position of the nail-linked fastener for loose paving of subway; the limiting part includes a first limiting part and a second limiting part, and the first limiting part A rail installation space for placing rails is reserved between the component and the second limiting component; the connecting device includes a first fixed pinch plate, a first pinch plate fixed plate, a second fixed pinch plate and a second pinch plate fixed plate. The invention can fix the nail-connected fasteners of subway loose pavement on the bottom of the steel rail, and two people can complete the installation of the fasteners without the need of four persons for installation.
Description
technical field [0001] The invention relates to the technical field of nail joint construction for loose pavement of subway tracks, in particular to a device for controlling installation of nail joint fasteners for loose pavement. Background technique [0002] The main construction technology for the laying of nail joints in the process of overhead line track laying is: scattered laying of nail joints on site. The speed and quality of nail joint laying directly affect the construction schedule and project cost. [0003] During the installation process of the loose-laid nail-linked fasteners, two workers are required to hold the fasteners by hand, and the other two workers pull the left and right elastic strips at the same time to complete the installation of the loose-laid nail-linked fasteners. This process requires four people to complete the fasteners The installation of nail joints consumes manpower. At the same time, if the installation of the left and right springs i...
