fig. 2 is a schematic view of a bridge cable maintenance device in the prior art when a bridge cable is maintained.
Detailed Description
As shown in fig. 1, the bridge cable maintenance device of the utility model comprises a maintenance platform 1, a traction cable driving device, a cable storage winch 7, a traction cable 2, an upper pulley 3, a lower pulley 4 and a reversing pulley 5 which are distributed along a bridge cable 8. The traction rope driving device is a friction winch 6, a rope storage winch 7 is installed on the maintenance platform 1 and located at the left lower end of the maintenance platform, a traction rope 2 is led out downwards from the rope storage winch 7 and in parallel with a bridge inhaul cable 8, continues to move forwards rightwards after winding on the lower pulley 4 and winds on a winding drum of the friction winch 6, then bypasses the reversing pulley 5 rightwards and continues to move upwards, and finally bypasses the upper pulley 3 and is connected with the upper right end of the maintenance platform 1. A traction rope fixing device 9 capable of preventing the rope storage winch 7 from releasing or recovering the traction rope 2 is arranged at the left lower end of the overhaul platform 1, and the traction rope fixing device 9 is a rope clamp or a wedge-shaped lantern ring. The traction rope 2 is a fiber rope, the tension of the fiber rope is small, and the phenomenon that multiple layers of ropes are sunk and wound can not occur in the rope storage winch.
During actual maintenance, the bridge cable maintenance device is installed as shown in fig. 1, because the length of a bridge cable is different, a traction cable fixing device 9 is opened firstly, then an upper pulley 3 ascends to the uppermost end of the bridge cable along the bridge cable and is fixed, meanwhile, a rope storage winch 7 releases or recovers a traction cable 2 along with the movement of the upper pulley 3, finally the traction cable 2 is in a tensioning state, then the traction cable fixing device 9 is closed, at the moment, the traction cable 2 passes through a lower pulley 4, a friction winch 6, a reversing pulley 5 and an upper pulley 3 from the left lower end of a maintenance platform 1 and then reaches the left upper end of the maintenance platform 1 to form tensioning closed loop connection, and the length of the traction cable 2 is kept constant during maintenance. In the maintenance process, when the maintenance platform 1 needs to be moved, only the friction winch 6 needs to be started, the roller of the friction winch 6 drives the traction cable 2 to move clockwise or anticlockwise, and the maintenance platform 2 stably moves up and down under the traction of the traction cable 2, so that the problem of impact generated when the maintenance platform is started due to the fact that the driving winch has the rope storage function and the driving function in the prior art is solved, and the safety of maintenance personnel is effectively guaranteed. The friction winch 6 is single-layer friction transmission, the positions of the rope in and out of the friction winch are always fixed and stable and reliable in transmission, and meanwhile, the traction rope fixing device 9 is closed during maintenance, so that the fiber rope wound into the rope storage winch is not stressed during maintenance, the phenomenon that the multilayer ropes of the conventional winch in the prior art are sunken and wound cannot occur in the friction winch and the rope storage winch, and meanwhile, the bridge inhaul cable maintenance device can effectively avoid accidents caused by the fact that the ropes are tied to be broken.
According to the bridge inhaul cable overhauling device, the overhauling platform can run more safely, stably and efficiently through the friction winch and the rope storage winch, the problems in the prior art are solved, the bridge inhaul cable overhauling device is simple in structure, safe and reliable, the safety of bridge inhaul cable overhauling work can be effectively guaranteed, the overhauling rate is greatly reduced, and the working efficiency is improved.
