Embodiment 1
[0028] Such as Picture 1-1 As mentioned above, the device adopts the principle of "hanging the old steel wire rope 10 with the new steel wire rope 2, and recycling the old steel wire rope 10 with the new steel wire rope 2". The old wire ropes 10 go into the well at one time, fix the two cages 11 and the friction wheels 7, remove the old wire ropes 10 from the connecting device, and after making a new rope head, remove the fixing devices of the two cages 11 and the friction wheels 7, so that the cages 11 The weight of the old steel rope 10 transitions to the new steel rope 2 to bear, that is, the task of "hanging on the old steel rope 10 with the new steel rope 2" is completed.
[0029] The components in the device are figure 1 The layout is fixed sequentially, and the rope is discharged from the new steel rope reel 1 that has stored a sufficient length of new steel rope 2. The new steel rope 2 first passes through the guide wheel II 12 and the anti-running rope mechanism 3, ...

The invention discloses a right angle type alternating and continuous replacing device for a plurality of head ropes of hoists, which comprises a rope running prevention mechanism, a continuous rope replacing mechanism, a guide wheel I, a guide wheel II, a hydraulic system and an electronic controlling device. The replacing device has the improvement that the guide wheel II is arranged in front ofthe rope running prevention mechanism to lead the direction of introducing new steel rope from a new steel rope reel and the pushing direction of the new steel rope in the rope replacing process to be 90 degrees, improvements are carried out on the continuous rope replacing mechanism and the hydraulic system to lead the plurality of head ropes to carry out the alternating and continuous rope replacement, thus enhancing the rope replacing efficiency and shortening the rope replacing time; and the whole set of the device is smaller in size and the wellhead space is saved, and the automatic control of the rope replacing process can be realized in an open-loop mode, thus increasing the automation degree and the safe reliability.
Description
technical field [0001] The invention relates to a rope changing device for a mine hoist, in particular to a device for synchronously and continuously changing multiple first ropes of the hoist. Background technique [0002] Coal mine friction hoist steel wire rope (that is, the first rope) generally has a service life of no more than 2 years. For mines where both the main and auxiliary shafts are friction hoists, the first rope needs to be replaced once a year on average. The safety risk of changing ropes for multi-rope friction hoists in mines is high, requiring less time at the wellhead. Because the underground operation is forced to stop during the rope change, the length of the rope change time directly affects the safe production of the coal mine. Shortening the rope change time and improving the safety of rope change can bring immeasurable economic benefits to the coal mining industry and the industries involved in coal.
