ABSTRACT
At present in the mine upgrade will happen from time to time in the slippery rope and a volume accidents, how to guarantee the safety of the production process, as well as an effective solution incidents, as far as possible to minimize losses. Rope control device is in a slippery rope, or a volume Piers LP, promptly and effectively seize the rope to prevent the further development of the accident.
The control device is a wire rope hoist rope sliding friction brake Kasheng rope device, in the same area-the volume can be used, simply to slip justice enter into a signal vol pier signal to the tank, mechanical grasping rope Some are the same, only different needs of the dynamic system, hydraulic power to be provided by different, in the normal time for justice can also be used for Kasheng. The braking devices, including fuel tanks, fuel tanks connected to the brake and pushed around the plate, Kasheng the wedge brake blocks to ensure that wedge brake block the movement from top to bottom roller row, the wedge-shaped brake blocks and a guide to the limit Limit sales for the reduction of the wedge brake block reset spring, for the brakes-oriented side of Rafah boards, cards and other pieces. When a slippery rope when the control system to produce down the side of a signal to the brakes, brake pressure oil into the fuel tank before the cavity, retractable rod so that the brakes down to the wire rope Baojin and braking, the system Hydraulic braking force by the adjustment of prior good pressure on the station identified. Need Kasheng, hydraulic station output will be adjusted to the maximum pressure, brake oil tank brake piston rod retractable steel cable, have Kasheng, insert the card at the same time block as a reserve safety protection.
Rope manipulation device features: through the shaft encoder can be monitored to detect abnormal conditions, quickly and effectively grasp the rope, easy installation, automatic and manual options. Under normal circumstances can change as a rope used to use one of the three devices.
Key words: rope upgrade, anti-skid, anti-off volume, multi-function control, rope-catching.
