Embodiment Construction
[0015] The present invention is described in detail below in conjunction with accompanying drawing:
[0016] A cable fixing and clamping mechanism for a cable reel for railway tunnel construction, including a box-shaped support body 1 for a cable storage reel. The box-shaped support body 1 is in the shape of a cuboid and can be placed on a trolley. support and realize the operation of retracting and releasing the cables; the left part of the box-shaped support body 1 is provided with a U-shaped groove 2 for placing the cable storage tray, and a Bearing 3 at the left end of the central axis of the storage tray, and a bearing 4 at the right end of the central axis of the storage tray is arranged on the right inner wall of the U-shaped groove 2 where the cable storage tray is placed, and bearing 4 at the left end of the central axis of the storage tray and the right end bearing 4 A central axis 5 of the storage tray is arranged between them, and a herringbone support hub 6 is fix...

The invention discloses a cable fixing and clamping mechanism of a cable disc for railway tunnel construction. The problem that during existing tunnel construction, a cable disc is prone to rotating on a cable disc frame, cables are released from winding, and collide with a frame body can be solved. A herringbone supporting hub (6) and a cable winding annular disc face (7) are fixedly arranged onthe center of a storage disc center shaft (5), a cable clamp placing horizontal through hole (16) and a cable clamp horizontal moving clamping rod (17) are arranged at the position, on the right sideof a cable placing storage disc U groove (2), of the top end of a box-shaped support body (1), the left end of the cable clamp horizontal moving clamping rod (17) is fixedly connected with a U fork (18) which is placed in the left and right horizontal direction, a U fork clamping tongue (22) is arranged on the upper end of the inner side wall of the right side in the cable placing storage disc U groove (2), a wound cable is arranged between the U fork clamping tongue (22) and the U fork (18), and automatic winding and releasing of the cables can be achieved; and it is ensured that in the moving process, wound cables cannot be separated out of winding.
Description
technical field [0001] The invention relates to a cable reel, in particular to a mechanism for fixing and clamping cables on the cable reel used in railway tunnel construction. Background technique [0002] At present, in the construction of railway tunnels, it is necessary to transport the cable reel to cooperate with the construction of the tunnel to complete the task of laying cables in the tunnel. The cable is usually twisted by several or several groups of wires, each group of wires is insulated from each other, twisted around a center, and the entire outer surface is covered with a highly insulating covering; the cable is generally wound on a cable drum, The transportation is realized by the car body that transports the cable reel; on the car body that transports the cable reel, there is generally a cable reel frame, and the cable reel is set on the cable reel frame; during the transportation, the cable reel is easy to rotate on the cable reel frame, Make the cable un...
