Abstract
The invention provides an improved sleeve coupling hoisting structure for a circulating water pump. The structure can effectively ensure normal and reliable hoisting and installation of a sleeve coupling. The structure comprises the sleeve coupling. The structure is characterized in that: two planes are milled at the upper and lower ends of the external circle of one end of the sleeve coupling, an annular groove is formed at the marginal parts of the two planes close to the middle of the sleeve coupling, a hoisting ring is clamped in the annular groove, and a hoisting lug is arranged on the hoisting ring.
Description
Technical field
The present invention relates to be used for the box coupling mounting technique field of circulating water pump, be specially the improved box coupling lifting structure that is used for circulating water pump.
Background technique
Can't boom hoisting be set at its end face because the face size of box coupling is less, so generally be lifting bolt 6 to be installed at the outer side surface of box coupling 1, see Fig. 1, boom hoisting lifts by crane sleeve by pulling lifting bolt 6, but thereby sleeve causes sleeve stuck with branch half clip owing to divide half clip to be prone to the phenomenon that gets loose in the lifting process, make lifting bolt easily broken by shear action, can't carry out the normal lifting of box coupling.
Summary of the invention
At the problems referred to above, the invention provides the improved box coupling lifting structure that is used for circulating water pump, its normal, reliable lifting that can effectively guarantee box coupling is installed.
Its technological scheme is such, it comprises box coupling, it is characterized in that: the upper and lower end of described box coupling one end cylindrical is milled with two planes, be provided with a circular groove on described two planes near the edge in the middle of the described box coupling, be installed with hoisting ring in the described circular groove, on the described hoisting ring hanger be installed.
It is further characterized in that: described hoisting ring internal orifice dimension and described circular groove cylindrical coupling.
Use box coupling lifting structure of the present invention, stressed even, reliable, difficult during its lifting owing to its hoisting ring is installed in the circular groove because of being sheared the excessive phenomenon of rupture that takes place, guaranteed normal, the reliably lifting installation of box coupling.
Description of drawings
Fig. 1 is existing box coupling lifting structural representation;
Fig. 2 is a box coupling lifting structural representation of the present invention;
Fig. 3 is middle sleeve coupling lifting tip side TV structure schematic representation of the present invention;
Fig. 4 is hoisting ring structural representation among the present invention.
Embodiment
See Fig. 2, Fig. 3 and Fig. 4, box coupling lifting structure of the present invention, it comprises box coupling 1, upper and lower end at box coupling 1 one end cylindricals is milled with two planes 2, be provided with a circular groove 3 on two planes 2 near the edge in the middle of the box coupling 1, be installed with hoisting ring 4 in the circular groove 3, hanger 5 is installed on the hoisting ring 4.Hoisting ring 4 internal orifice dimensions and circular groove 3 cylindricals coupling.
Specifically describe installation, the slinging work process of structure of the present invention below: hoisting ring 4 snaps fits into circular groove 3 along upper and lower two planes 2 of box coupling 1 end cylindrical, then hoisting ring 4 is revolved along circular groove 3 and turn 90 degrees, guarantee fitting tightly between hoisting ring 4 and the circular groove 3, boom hoisting lifts by crane box coupling 1 by the hanger on the hoisting ring 4.
