Attached auxiliary wire rope.

In this structural design, the setting of the fixed pulley enables both the reel and the fixed pulley to bear the total weight of the hanging box; double safety is formed, and when the hanging box in the front and rear wellheads is lifted, the other hanging box is under the influence of gravity. Under the action, a lifting force is given to the hanging box through the fixed pulley, which reduces the lifting force of the deceleration braking motor and further improves the energy saving effect.

A high-efficiency and energy-saving hoisting device used in mine operation, further comprising a controller and a limit switch located on one side of the hoisting trolley in the traveling direction, the output end of the limit switch is connected with the input end of the controller, and the output end of the controller is connected with the deceleration brake The input of the motor is connected.

During operation, when the hoisting trolley moves to the contact limit switch, the hanging box reaches the specified depth, and the limit switch controls the deceleration brake motor to reverse rotation through the controller.

The structure design of the invention is reasonable and reliable, realizes the time alignment of the wire rope and the wellhead, and the alignment of the wire rope and the drum without being squeezed, ensures the accurate lifting of the wire rope, and prevents the occurrence of the wire rope breakage, and has a small footprint and is safe. The performance is improved, the measured lifting force is single and accurate, the working area is shared, the operation efficiency and energy saving effect are remarkable, and the utility model has the advantages of simple structure, convenient processing and low cost.
