Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a mould for railway contact network foundation construction. Background Art

[0002] The overhead contact network is a high-voltage transmission line that is erected in a zigzag shape above the rails in an electrified railway and is used to supply current to the pantograph. The overhead contact network is the main structure of the railway electrification project and is a special form of transmission line erected above the railway line to supply power to electric locomotives. It consists of contact suspension, supporting devices, positioning devices, pillars and foundations.

[0003] Some existing molds for railway contact network foundation construction are not easy to demould in actual use, and the most difficult and time-consuming process in the contact network foundation construction is the fixation, positioning and verticality of the embedded bolts. Each contact network foundation has 8 M39 embedded bolts. If the bolt positioning is inaccurate, the contact network columns cannot be installed during the subsequent four-electric construction, resulting in a large amount of subsequent rework. Since the size of the contact network foundation is relatively single, bolt fixing positioning frames and matching templates can be manufactured and processed. By solving the precise positioning and fixing of the embedded bolts, it is convenient for installation, disassembly and turnover. Utility Model Content
