Detailed ways

The present invention will be further described below according to the accompanying drawings and embodiments.

As shown in the accompanying drawings, a comprehensive protection device for mine hoisting rope catching rope, adjusting rope, and stuck rope includes a base 11 on which a lower catching manipulator 7 and a rope baffle 8 are mounted, and a lower catching manipulator 7 There are screw rods 9 and guide shafts 10 horizontally connected with the rope baffle plate 8. The screw rods 9 are installed on the synchronous boxes 3 on both sides of the base 11. The screw rods 9 and the lower The catching manipulator 7 and the rope-holding baffle 8 are spirally connected, and the guide shaft 10 is slidably connected with the described lower catching manipulator 7 and the rope-holding baffle 8; The stepper motor I1 that moves and the stepper motor II2 that controls the capture force of the lower capture manipulator 7, the two ends of the stepper motor I1 are connected to the synchronization box 3; the two ends of the base 11 A guide post 5 is vertically installed on the side, and there is an up-adjusting rope manipulator 6 between the guide posts 5 on both sides. Stepping oil cylinders 4 are installed on both sides, and the two stepping oil cylinders 4 on each side are respectively hinged with the front and back sides of the lifting rope manipulator 6, and the stepping oil cylinders 4 and guide columns 5 are fixed on the same base plate. The bottom plate of the guide column 5 is slidingly connected with the base 11 , and a sliding oil cylinder 12 is installed between the bottom plate of the guide column 5 and the base 11 .

There are 4 to 8 groups of the number of manipulators of the described upper rope manipulator 6 and the lower catching manipulator 7.

The present invention can arbitrarily select the rope and the number of ropes when the hoisting system adjusts the ropes and locks the ropes.

The invention integrates the functions of rope catching, rope adjustment and rope clamping, and meets the space requirements of the derrick.

When the hoisting system appears to be in the state of slipping rope or slipping the car, the device performs the action of catching the rope, the stepping motor Ⅰ1 is connected with the screw rods 9 on both sides, and the lower catching manipulator 7 and the rope holding baffle 8 are driven by the synchronous box 3 Move along the guide shaft 10, the captured first rope enters the palm of the capture manipulator, and the palm of the capture manipulator is driven by the stepping motor II2 to capture the lifting first rope with a limited capture force;

When the hoisting system needs to adjust the first rope, the device performs a rope adjustment action. The lower catching manipulator 7 is first in place to catch the hoisting first rope, and the upper rope adjusting manipulator 6 is pushed by the sliding cylinder 12 to be in place along the guide rail on the base 11. . When adjusting the rope, the upper rope-adjusting manipulator 6 moves along the guide column 5 driven by the stepping oil cylinder 4, and interacts with the lower catching manipulator 7 to grasp the rope to realize the upward opening function and complete the rope-adjusting operation. Catching manipulator 7 is at first put in place, realizes the downward action of lifting head rope and catches. Under the push of sliding oil cylinder 12, the upper rope manipulator 6 is in place on the upper side of the lower catching manipulator 7, and the upper rope manipulator 6, under the action of the stepping oil cylinder 4, catches the upper side of the manipulator 7 from the lower side and grabs the upper side of the first lifting rope. Lift and release the lower capture manipulator 7. When the upper rope adjustment manipulator 6 reaches the upper limit of the stepping mechanism, the lower capture manipulator 7 grabs the first rope again, and the upper rope adjustment manipulator 6 releases the first rope and moves back one step. . When the stepping mechanism reaches the lower limit, the upper rope manipulator 6 grabs the first rope again, and repeats the above steps after completing one step length to realize the adjustment work of the first rope. After the rope adjustment is finished, the upper rope manipulator 6 withdraws, and the device catches the rope function and is in a waiting state.

When the hoisting system needs to block (fix) the first rope, the device performs a rope clamping action, the hoisting system is in a static state, and the lower catching manipulator 7 catches and lifts the first rope to achieve the purpose of blocking the first rope.
