By adopting the technical scheme, when the bearing box gland is disassembled, firstly, the bolt between the gland and the box body of the bearing box is disassembled, then the gland is pried upwards by using a spanner or other tools, the nut is placed on the upper edge of the box body and corresponds to the threaded hole on the box body, the bearing ring is stacked on the nut, then the screw rod vertically penetrates through the bearing ring downwards from the through holes on the two sides of the gland and is in threaded connection with the nut, the screw rod is screwed into the threaded hole of the box body, and finally, the lower end of the screw rod is fixed; and finally, the screw nut is rotated to separate the screw rod from the gland, and the gland can be lifted by the crown block to finish the disassembly. The gland is separated from the bearing box and the internal parts by adjusting the dismounting tools of each group in the whole process, then the gland is hoisted by using a crane, the hoisting process is smoother, and the bearing box and the internal parts thereof cannot be collided and damaged.
The present invention may be further configured in a preferred embodiment as: the lead screw is also sleeved with a gasket;
the bearing ring is positioned between the nut and the gasket.
By adopting the technical scheme, in the operation process, the gasket is positioned between the lower end faces of the pressure-bearing ring and the gland, so that the relative friction between the pressure-bearing ring and the gland can be avoided, and the pressure-bearing ring and the gland are effectively protected.
The present invention may be further configured in a preferred embodiment as: and the side surface of the pressure-bearing ring is also provided with a limiting component for preventing the gland from slipping.
Through adopting above-mentioned technical scheme, at the dismantlement in-process, need upwards rotate the screw, until gland and bearing box internals separation, remove the cooperation relation, but at the in-process of rotating the screw, probably master not good yardstick, lead to lead screw and bearing box gland to separate, the gland can be to both sides slippage this moment, sets up spacing subassembly and can effectively avoid this phenomenon.
The present invention may be further configured in a preferred embodiment as: the limiting assembly comprises a nut fixed on the side surface of the pressure bearing ring and a screw rod in threaded connection with the nut;
the screw rod is parallel to the screw rod.
Through adopting above-mentioned technical scheme, the screw rod is on a parallel with the lead screw, and is located the both sides of gland respectively, and under the condition of lead screw and gland separation, whole extracting tool still fixes on the bearing box, and the upper end of screw rod upwards extends and surpasss the gland, and the screw rod keeps off in the both sides of gland, plays limiting displacement to the gland, can prevent effectively that the gland from slipping to both sides.
The present invention may be further configured in a preferred embodiment as: and a knob is fixed at one end of the screw rod.
By adopting the technical scheme, the screw rod is convenient to rotate, and the length of the screw rod extending out of the upper end face of the pressing cover is adjusted.
The present invention may be further configured in a preferred embodiment as: the knob is plum blossom-shaped.
Through adopting above-mentioned technical scheme, increase the frictional force between staff's hand and the knob, it is more laborsaving to spin the screw rod.
To sum up, the utility model discloses a beneficial technological effect does:
1. after the lower end of the screw rod is fixed on the edge of the bearing box, the gland can be jacked upwards by rotating the screw nut, the gland is separated from the bearing box and the internal parts by adjusting each group of dismounting tools, then the gland is hoisted by using a crane, the hoisting process is smoother, and the bearing box and the internal parts thereof cannot be collided and damaged;
2. through the setting of spacing subassembly, can effectively prevent the gland slippage, strengthened the security in the operation process.
