Description

TECHNICAL FIELD

[0001] The utility model belongs to subway cable laying technical field especially relates to subway new line later period and existing line cable laying construction, concretely relates to a horizontal air valve cable laying protection device. BACKGROUND

[0002] Most of the subway power supply substations are underground substations. Since the subway new line construction is in the later period, and the mechanical and electrical civil construction of the existing line tends to end, the hoisting opening in the station is closed, the whole cable for power supply cannot be hoisted, and the cable can only be transferred to the platform layer for laying work through the mechanical and electrical horizontal air valve. The cross section of the 40.5KV high-voltage cable is thick, and the weight is large. It is difficult to control during laying, and it is easy to swing in an undefined direction. Since the horizontal air valve fan blade is long and has no reinforcement point in the middle, it is easy to be scratched by the cable, causing damage to the horizontal air valve fan blade and the cable insulation layer, and it is difficult to replace in the later period.

[0003] At present, many people need to be protected during the cable laying process of the horizontal air valve. The cable stress point needs to be adjusted at any time. When deviation occurs, the cable laying is stopped. After the cable is repositioned, the cable laying operation continues. This not only wastes manpower, but also greatly limits the cable laying speed. After the cable laying is completed, the cable itself and the horizontal air valve are severely worn, and the horizontal air valve fan blade and the traction device are damaged to varying degrees.
