Abstract
The utility model relates to a shaft sleeve remover which mainly solves the problems of low working efficiency and damage to the shaft sleeve and the main shaft during the repair and maintenance of a centrifugal pump in the prior art. The shaft sleeve remover is characterized in that: a power fixture (3) for fixing a jack (5) is arranged at the lower middle part of a top plate (1), pulling pieces (7) are arranged on both sides of the lower part of the top plate (1), pulling claws (8) are arranged at the lower part of the pulling pieces (7), and a pump shaft-fixing groove (6) is formed at the lower part of the jack (5). The shaft sleeve remover has the advantages of large pulling force, high efficiency and reduced damage to the shaft sleeve and other parts during the disassembly.
Description
Technical field:
The utility model relates to the accessory on a kind of centrifugal water pump, especially a kind of axle sleeve stripping attachment.
Background technology:
When existing centrifugal water pump was maintained, because the never axle sleeve provision for disengagement of standard can only use manpower to dismantle by force, efficient was low, and often causes the damage of axle sleeve and main shaft, makes maintenance work not reach desired effects.
The utility model content:
Inefficiency, the deficiency that often causes axle sleeve and main shaft to damage when overcoming the maintenance of current centrifugal pump, the utility model provides a kind of axle sleeve stripping attachment, this axle sleeve stripping attachment has that pulling force is big, efficient is high, can reduce that axle sleeve and miscellaneous part damage during dismounting characteristics.
The technical solution of the utility model is: the axle sleeve stripping attachment comprises top board, jack, and there is the fixedly dynamic fixation device of jack at middle part, top board below, and there is the ear that draws of bottom band pulling claw both sides, top board below, and the pump shaft holddown groove is installed in the jack bottom.
The utlity model has following beneficial effect: owing to take such scheme, adopt jack as power, pulling force is big, reduces dismounting labour intensity, and the efficient height reduces maintenance time, and safety, energy-saving and environmental protection; By the pulling claw fixed hub, during the dismounting axle sleeve, can reduce the damage of axle sleeve and miscellaneous part, reduce maintenance cost.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
1-top board among the figure, the 2-bearing pin, 3-dynamic fixation device, the 4-pin, the 5-jack, 6-pump shaft holddown groove, 7-draws ear, 8-pulling claw, 9-bolt.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the axle sleeve stripping attachment comprises top board 1, jack 5, there is the fixedly dynamic fixation device 3 of jack 5 at middle part, top board 1 below, dynamic fixation device 3 is by the fixing jack 5 of pin 4, jack 5 can be pulled down when not working, during work, utilize the power dismounting axle sleeve of hydraulic jack 5, saved manpower; Both sides, top board 1 below have two to draw ear 7 by what bearing pin 2 connected, when installation, dismounting centrifugal pump, draw ear 7 to rotate around bearing pin 2, drawing ear 7 bottoms is pulling claw 8, two pulling claws 8 are hollow semi-cylindrical in configuration, and during work, axle sleeve places in the hollow cylinder of two pulling claws, 8 formations, fix two pulling claws 8 by bolt 9, make pulling claw 8 become as a whole with axle sleeve; Pump shaft holddown groove 6 is installed in jack 5 bottoms, during work, pump shaft is fixed in the groove, prevents the stressed hour offset of pump shaft.
During the dismounting axle sleeve, earlier jack 5 is fixed on the dynamic fixation device 3, then jack 5 is adjusted to suitable length, pump shaft is placed on centering in the pump shaft holddown groove 6, ear 7 is drawn in rotation, two halves pulling claw 8 is fixed on the axle sleeve, screws bolt 9, as a whole to reach axle sleeve with 8 one-tenth of pulling claws, at this moment, press hydraulic jack 5, utilize the reaction force of jack 5, axle sleeve is unloaded on pump shaft.
Claims (1)
1. axle sleeve stripping attachment, comprise top board (1), jack (5), it is characterized in that: there is the fixedly dynamic fixation device (3) of jack (5) at middle part, top board (1) below, what there was a bottom band pulling claw (8) both sides, top board (1) below draws ear (7), and pump shaft holddown groove (6) is installed in jack (5) bottom.
