Description

TECHNICAL FIELD

[0001] The utility model relates to cutting auxiliary equipment technical field especially based on the water cutting machine's anchor withdrawal tooling. BACKGROUND

[0002] In the operation of coal mine and the like, a roof is arranged on the top of a roadway in the coal mine for safety, and the roof is generally fixed by anchor rods and anchor bolts. When the roof needs to be removed, the anchor bolts are removed by tools, and then the roof can be removed. In actual situations, there is a probability of gas leakage in the coal mine and the like, and the electric cutting and gas cutting methods for removing the anchor bolts may generate sparks in the process, thereby increasing the probability of explosion accidents. Therefore, in the prior art, the anchor bolts are generally cut by a water jet cutter (water cutting machine). Since the anchor bolts are high, the worker needs to climb (for example, stand on a ladder) to hold the water jet cutter head to cut the anchor bolts. The above operation method not only brings inconvenience to the worker, but also increases the probability of injury of the worker falling from a high place.

[0003] With the progress of industrial technology, the technology of cutting anchor bolts by a water jet cutter in a coal mine has also been developed. For example, Chinese Patent No. 202222128014.4, entitled "Special device for removing anchor cable by water cutting", records that when the special device is used to remove the anchor cable, the positioning sleeve is sleeved on the anchor cable to be removed, and the magnet is attracted to the lower end of the anchor cable tray of the anchor cable to be removed. The special device for removing the anchor cable by water cutting can be used for removing the anchor cable in a mine, has high safety, is easy to operate, and is suitable for water cutting operation. It can be seen that although the worker can control the movement of the water cutting cutter on the ground in the comparative patent (the comparative patent is actually a water cutting anchor removal device), thereby cutting the anchor bolt (anchor cable), the worker still needs to climb to attract the magnet to the lower end of the anchor cable tray of the anchor cable to be removed before work, and also needs to climb to remove the magnet after work. The above operation still brings inconvenience to the worker and has certain safety hazards. In addition, the magnet attraction method cannot achieve effective fixation. When the weight of the related equipment at the lower end of the magnet is relatively large, or the vibration is large (the water cutting jet cutter itself vibrates greatly or other equipment in the coal mine vibrates and the vibration force is transmitted to the anchor cable tray), or the lower end of the anchor cable tray is not flat, etc., the magnet and the lower end of the anchor cable tray may be separated, thereby adversely affecting the cutting work and also having safety hazards.
