Description
Technical field
The utility model relates to hoisting technology fields, and in particular to the tubular shaft type that one kind can reduce hoisting rig frictional force is hung
Ear.
Background technique
In chemical plant installations construction, for large-scale vertical tower class equipment, equipment hoisting is carried out using tube shaft type lifting lug
Technique ten branch, but lifting is directly hung on lifting lug with wirerope and carries out lifting overturning operation, wirerope is born
Larger frictional force causes rigging impaired, the technical issues of greatly reducing service life, be always construction.The prior art is mainly managed
Axial lifting lug is directly contacted with wirerope, so that during equipment is by level to vertical state, wirerope and lifting lug contact site
Larger frictional force is assumed responsibility for, service life is greatly reduced.The lifting lug being related to, which refers to, to be mounted on equipment for being promoted or being led
Draw the suspension centre structure of equipment；Tube shaft type lifting lug is a kind of form of lifting lug used for hoisting, is mainly used for equipment master and hangs.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, solve between tube shaft type lifting lug and wirerope
Frictionally damage, a kind of tube shaft type lifting lug that can reduce hoisting rig frictional force is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tube shaft type lifting lug reducing hoisting rig frictional force is welded in which on hanging device, the lifting lug is arranged
There are two and be located at top to hanging device, and be in symmetric form relative to the central axes to hanging device, lifting lug is by reinforcement
Plate, pipe axis, sleeve and baffle composition, the welding with reinforcement plate in the cylinder body outer wall to hanging device, one end of the pipe axis with
Integral to hanging device cylinder and welding with reinforcement plate, another to weld with the baffle, the sleeve is socketed on the pipe axis
Outer wall is evenly equipped with 6~12 oil filler points in sleeve wall, for filling lubricating oil before impaling wirerope.
Further, the centre distance of the lifting lug waits for being 1m~2.5m at the top of hanging device.
Further, the pipe shaft material is Q235, Q245R or Q345.
Further, the pipe axis is by caliberSteel pipe constitute, thickness of steel pipe be 8mm~
40mm。
Further, the sleeve material is Q235, and sleeve diameter is 8mm or more bigger than the outer diameter of pipe axis.
Compared with prior art, beneficial effect brought by the technical solution of the utility model is:
1. the utility model lifting lug can effectively avoid the abrasion using wirerope in prior art lifting lug hoisting process, really
It is intact to protect hoisting rig quality.
2. the utility model uses the technical measures of the additional sleeve of tube shaft type lifting lug, while guaranteeing Hoisting Security, by
Sleeve replaces wirerope and lifting lug to carry out rolling friction, avoids lifting lug and contacts with the direct of wirerope, it is ensured that hoisting rig
Safety.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference: 1- cylinder body outer wall, 2- stiffening plate, 3- pipe axis, 4- sleeve, 5- baffle
Specific embodiment
The utility model will be further described with reference to the accompanying drawing.
As shown in Figure 1, one kind can reduce the tube shaft type lifting lug of hoisting rig frictional force, lifting lug setting in practical lifting operation
There are two and be welded on the cylinder body outer wall 1 to hanging device, two lifting lugs are respectively relative to the central axes pair to hanging device
Claim, for distance to be 1m~2.5m at the top of hanging device, lifting lug primary structure includes pipe axis 3, stiffening plate 2, baffle 5 and sleeve 4, past
Erecting and welding order is followed successively by stiffening plate 2, pipe axis 3, sleeve 4 and baffle 5 on cylinder body outer wall 1；Pipe axis 3 select steel pipe and with wait hang
Fill the identical steel material of apparatus body, such as Q235, Q245R, Q345 material；The caliber range of the selection steel pipe of pipe axis 3 are as follows:Thickness of steel pipe range is 8mm~40mm；4 material selection Q235 of sleeve, sleeve diameter=pipe axis outer diameter
+ 8mm, length sleeve=lifting lug hold rope width -20mm；Uniformly distributed 6~12 oil filler points, fill before impaling wirerope in sleeve wall
Butter lubrication.
The utility model lifting lug prolongs in EOEG project in Saudi Arabia's card for being lifted simultaneously to large-scale vertical tower
Immense success is obtained, the practicality and reliability have been fully demonstrated.
The utility model is not limited to embodiments described above.Above the description of specific embodiment is intended to describe
With illustrate the technical solution of the utility model, the above mentioned embodiment is only schematical, is not restrictive.?
In the case of not departing from the utility model aims and scope of the claimed protection, those skilled in the art are practical at this
The specific transformation of many forms can be also made under novel enlightenment, these are belonged within the protection scope of the utility model.
