Abstract

The invention belongs to the field of track maintenance, and provides switch long and heavy part replacement equipment. The switch long and heavy part replacement equipment includes a base, the base is fixedly provided with a reversing mechanism, the reversing mechanism is composed of a guide rail and a locking mechanism, the reversing mechanism is fixedly provided with a rotary support, the rotary support is fixedly provided with a vertical column, the vertical column is provided with a folding arm, a hook and a supporting column, the hook and the supporting column are capable of sliding on the folding arm, the folding arm is further provided with a synchronous device, the fixed part of the synchronous device is installed on the folding arm, the moving part of the synchronous device is arranged on the hook, and the base is further provided with a cargo bogie and a connecting seat for connecting a flatcar. According to the switch long and heavy part replacement equipment, through a hang arm capable of being folded, rotated and reversed, the specialization of the long and heavy part replacement equipment of high-speed railway turnout is realized, replacement operation time is shortened, the stability of replacement operation is improved, the risk of replacement operation is decreased, the construction efficiency is high, and replacement quality is better.

Description

technical field [0001] The invention belongs to the field of track maintenance, and in particular relates to a switch long and heavy part replacement device for transporting and replacing high-speed railway turnout long and heavy parts. Background technique [0002] At present, the replacement of long and heavy parts of domestic high-speed railway turnouts faces difficulties such as short operating time and lack of effective special equipment. The long and heavy parts of the turnout are generally transported to the work site by a special railway flat car, and then hoisted and replaced by a truck crane. Due to the closed nature of the high-speed railway, it is difficult for truck cranes to reach the work site. Truck cranes have high jib heights and are at risk of touching or damaging the catenary above the railway. In addition, the use of truck cranes to hoist the turnouts has poor synchronization, large swings, and low construction efficiency. Contents of the invention ...
