Description

Technical Field

[0001] This utility model relates to the field of construction equipment, specifically to a multifunctional adjustable integrated contact wire welding jig. Background Technology

[0002] The overhead contact system is the core construction equipment for electrified railways and urban rail transit. It provides power to electric locomotives or subway trains through high-voltage transmission lines erected above the track. The overhead contact system consists of four main parts: contact suspension, support device, positioning device, and pillars and foundations. It transmits electrical energy to the train drive system through the sliding contact between the pantograph and the contact wire. It has no backup characteristics, which directly affects operational safety.

[0003] Currently, the installation of pre-embedded bolts for the contact network of precast box girders in high-speed railways is done manually by laying out lines and positioning them. After the steel cage is hoisted into the formwork, the contact network bolts and steel plates are pre-embedded on the beam. The pre-embedding process cannot be accurately positioned, and it is easy for the whole structure to shift or deviate. In addition, the operation time is long and the efficiency is low. Furthermore, after the steel reinforcement is installed, there are many control variables, and it is easy for the pre-embedded steel reinforcement to be crooked and have large positive and negative errors in the exposed height. Moreover, during the concrete pouring and vibration process at the contact network of the beam, bolt tilting and overall misalignment are likely to occur. To address these issues, a multi-functional adjustable integrated contact network welding jig is proposed. Utility Model Content
