Problems solved by technology
[0003] With the trend of large-scale coal mine hydraulic supports, it is more difficult to disassemble the threaded guide sleeve in column repair
For example, when the cylinder diameter of the column is Φ400, the torque required to disassemble the threaded guide sleeve of the old column is about 50KNm. According to the traditional design, to achieve the general disassembly speed, a power of 50-100 kilowatts must be configured, and its transmission system will also be relatively bulky

The invention discloses a guide sleeve detaching machine for a large-torsion mining vertical column. The guide sleeve detaching machine comprises a frame and is characterized in that: a fixing plate is mounted on the frame; a force-applying ring is rotatably mounted on the front end face of the fixing plate; a guiding slot is distributed on the force-applying ring; a ratchet is mounted in the guiding slot through a spring; a ratchet wheel which is matched with the ratchet is arranged in the force-applying ring; a lug boss correspondingly matched with a guide slot, groove or hole on a to-be-screwed workpiece is distributed on an inner circle of the ratchet wheel; a working jack is used for driving the force-applying ring to rotate; and the working jack is fixedly mounted on the frame on one side of the fixing plate or extending edges on two sides of the fixing plate. The guide sleeve detaching machine is reasonable in structure design; the guide sleeve detaching machine is screwed and clamped by utilizing an external force; the guide sleeve detaching machine has a screwing self-locking structure; after being screwed and clamped, the guide sleeve detaching machine is difficult to loosen; and the guide sleeve detaching machine meets the demands on high-strength screwing and clamping.
Description
technical field [0001] The invention relates to a new type of device for dismantling threaded guide sleeves of columns by using a small power source in the repair of hydraulic supports used in coal mines, in particular to a large-torque mine column guide sleeve removal machine. Background technique [0002] At present, a considerable part of the column of the coal mine hydraulic support adopts a threaded guide sleeve structure. In the manufacturing process of the column, mechanical devices are generally used in the process of assembling and disassembling the threaded guide sleeve; at this time, the torque required for assembling and disassembling the threaded guide sleeve is not large. For example, the torque required for assembly and disassembly of a threaded guide sleeve with a middle diameter of about Φ200 is about 200Nm. It is relatively easy to realize mechanized assembly and disassembly. The required torque is much greater than that of a new column. Similarly, for th...
