Abstract
A hoisting cover device for lubricating and hoisting of a hanging shaft of large equipment consists of a hoisting lug plate, a flange flat clover, a hoisting screw, a shaft hole, a boss, a bolt hole, an oil storage tank, a hanging shaft, a hoisting bolt, an open flange at the top of the equipment and a hoisting rigging. The utility model mainly provides a hoisting cover for large equipment, which can improve the lubricating effect of the hanging shaft and reduce the shear degree of the hoisting bolt. The utility model improves the two weak parts in the hoisting operation of the large equipment in the following: (1) the boss is added at the lower part of the flange flat cover to bear partial lifting force so as to reduce the shear degree of the hoisting bolt; and (2) the oil storage tank is added in the shaft hole of the hoisting lug plate to improve the lubricating effect of the hanging shaft so as to reduce the damage degree when the hanging shaft is in friction rotation with the shaft hole under stress, thereby effectively ensuring the hoisting safety of the large equipment.
Description
Affiliated technical field:
The utility model relates to a kind of lifting and hangs lid arrangement, the lubricated lid arrangement that hangs of especially a kind of main equipment hanging axis.
Background technology:
At present, " the lifting hanger is one of key factor of decision lifting operation success or not.During conventional the lifting, the lifting hanger is welded on the apparatus body.For high-tension apparatus or main equipment,,, adopt blind flange shape to hang lid usually according to the version of apparatus body for avoiding welding influence to apparatus body.Blind flange shape is hung lid and is made up of orthogonal lifting otic placode and flange flat cover two parts, and the lifting otic placode is connected with other lifting rigging by hanging axis, and the flange flat cover links to each other with equipment open top flange by the lifting bolt.
It generally is the solid forging structure that the blind flange shape that the main equipment lifting is used is hung lid, and the load-carrying capacity that hangs lid itself does not have problems.But hanging the weak link that is stamped the pass with lifting in the hoisting process has 2 points: the one, and being through hanging axis in the lifting otic placode axis hole can the rotation an angle of 90 degrees in the equipment hoisting process, and hanging axis will inevitably sustain damage during with axis hole friction rotation under stress condition; The 2nd, can be subjected to bigger shearing force with flange flat cover bonded assembly lifting bolt in the equipment lifting stage.
Along with the constantly needs of expansion and the improving constantly of device fabrication and transport capacity of enterprise's manufacturing scale, main equipment integral hoisting weight is also constantly soaring.Therefore, the necessary design angle that hangs lid from lifting considers, reduce above-mentioned with hang two weak links that are stamped the pass, assurance lifting operation safety.Now provide following summary of the invention in order to address the above problem.
The utility model content:
The purpose of this utility model provides the lubricated lid arrangement that hangs of a kind of main equipment hanging axis, to satisfy the needs of main equipment lifting.Hang the design angle of lid from lifting and consider,, improve the hanging axis lubricant effect to reduce its damaged degree during with axis hole friction rotation under stress condition at the inner oil resevoir that increases of lifting otic placode axis hole; Increase boss in flange flat cover bottom, make it bear a part of hoisting force and cut degree to reduce the lifting bolt.After blind flange shape is hung lid and forged lifting otic placode and the preliminary shape of flange flat cover by the monoblock steel ingot, carry out machinework and form.On lifting otic placode line of centers, be provided with the axis hole that is used to connect hanging axis apart from flange flat cover upper surface appropriate location, shaft hole inner wall is being ground and reducing on the basis of its roughness of surface as far as possible, increase several hoop oil resevoirs at shaft hole inner wall, can improve the lubricant effect of hanging axis in axis hole in the hoisting process, preventing to take place between hanging axis and the axis hole hard grind effectively wipes, thereby greatly reduced hanging axis damaged degree during with axis hole friction rotation under stress condition, can guarantee lifting operation safety.
Be processed with on the flange flat cover and equipment open top flange bolt hole one to one, the flange flat cover links to each other with equipment open top flange by the lifting bolt.For reducing the lifting bolt particularly lifts by crane the stage in the equipment hoisting process the degree of being cut, be provided with the boss that is complementary with equipment open top internal diameter in flange flat cover bottom, this boss contacts with equipment open top flange inner wall and is stressed, thereby born a part of hoisting force to a great extent, reduced the suffered shearing force of lifting bolt in the hoisting process.Said apparatus is by lifting otic placode 1, flange flat cover 2, and lifting screw 3, axis hole 4, boss 5, bolt hole 6, oil resevoir 7, hanging axis 8, lifting bolt 9, equipment open top flange 10, lifting rigging 11 constitutes.
The technical solution of the utility model is: flange flat cover 2 upper surfaces are provided with lifting otic placode 1, and lifting otic placode 1 middle part is provided with axis hole 4, and axis hole 4 inside faces are provided with oil resevoir 7; Flange flat cover 2 lower surfaces are provided with boss 5, and flange flat cover 2 two ends and flange flat cover 2 parallel facess are provided with through hole bolt hole 6, and through hole bolt hole 6 is corresponding with the hole for hoist of equipment open top flange 10; Lifting screw 3 is set on flange flat cover 2 one end faces; Boss 5 is arranged on equipment open top flange 10 middle parts, and bolt hole 6 is provided with lifting bolt 9 with the Kong Xiangzhong of equipment open top flange 10, and hanging axis 8 is set in the axis hole 4, and hanging axis 8 two ends are provided with lifting rigging 11.
Beneficial effect:
The beneficial effects of the utility model are, mainly provide a kind of and can improve the hanging axis lubricant effect and reduce the lifting bolt and cut the main equipment of degree and hang lid.Hang the design angle of lid and consider that the structure of lifting being hung lid is optimized.Make and do not belong to the self-bearing capacity problem of covering of hanging before this, but hanging two weak links that are stamped the pass with lifting in hoisting process is effectively improved: promptly one is to increase boss in flange flat cover bottom, makes it bear a part of hoisting force and is cut degree to reduce the lifting bolt; The 2nd, at the inner oil resevoir that increases of lifting otic placode axis hole, improve the hanging axis lubricant effect to reduce its damaged degree during with axis hole friction rotation under stress condition.After two weak links of main equipment lifting operation are improved, can guarantee main equipment lifting safety more effectively.
