Abstract
The invention discloses a lifting tool for lifting large annular parts. The lifting tool for lifting the large annular parts comprises a lifting shoulder pole, wherein pin shaft mounting bases are symmetrically arranged at two ends of the lifting shoulder pole; at least two radial pin shaft holes are formed in each pin shaft mounting base; the pin shaft holes are formed in the same circumference; pin shafts are mounted in the pin shaft holes; sleeves are correspondingly arranged on the pin shaft mounting bases and arranged at one ends of the pin shafts in a sleeving manner; the sleeves are fixedly arranged on the pin shaft mounting bases; a telescoping mechanism is mounted between the sleeves and the pin shafts and used for controlling the pin shafts to extend and retract. The lifting tool for lifting the large annular parts and annular entities are rigidly fixed by virtue of the pin shafts to form an integral body; the danger caused by motion between the lifting tool and workpieces can be avoided during lifting; the safety and reliability of lifting are ensured; meanwhile, the lifting tool for lifting the large annular parts is simple in structure and high in operability.
Description
Technical field
The present invention relates to a kind of suspender for large-sized ring part lifting.
Background technology
In large size bearing processing, the ring-like entity of thrust collar generally, and generally workpiece.Its upper surface and outer shroud
Face is important machined surface, high to its machining accuracy, suface processing quality requirement, does not allow to weld hanger, nor presence is hung
Hole.The lifting to carry out the first-class annular workpieces of thrust for the mode often being coordinated with chain block using many suspender belts at present.Using
When many suspender belts are lifted, because fixing to it in the circumferential, suspender belt sliding may be led in lifting, draw
Send out danger.Therefore, need to be lifted using safe and reliable, rational hanging method, in order to avoid causing the damage of machined surface and adding
The lifting deformation of workpiece, and guarantee Hoisting Security.
Content of the invention
The technical problem to be solved is to be easy to pacify for not enough offer one kind that above-mentioned prior art exists
The suspender of steady, the safe and reliable large-sized ring part lifting of dress, lifting.
The technical solution adopted in the present invention is: for large-sized ring part lifting suspender it is characterised in that: include lifting
Shoulder pole, is symmetrically arranged with bearing pin mounting seat at the two ends of lifting shoulder pole, is at least installed on two footpaths in each bearing pin mounting seat
To pin shaft hole, each pin shaft hole is distributed on same circumference, installs bearing pin in each pin shaft hole, corresponding in bearing pin mounting seat
It is provided with sleeve set one end in bearing pin, described sleeve is fixedly installed in bearing pin mounting seat, pacify between sleeve and bearing pin
It is provided with the telescoping mechanism for the contracting of control pin shaft extension.
By technique scheme, the joining of the centrage of each pin shaft hole is located on the centrage of lifting shoulder pole.
By technique scheme, described telescoping mechanism includes screw rod, and described screw rod is connected with pin shaft thread after penetrating sleeve,
The external end head of screw rod is provided with spanner interface.
By technique scheme, bearing pin mounting seat is located at and above sleeve, is provided with gusset.
By technique scheme, it is symmetrically arranged with hanger at the two ends of lifting shoulder pole.
By technique scheme, two pin shaft holes are provided with each bearing pin mounting seat, positioned at two pins at opposite slightly to the right or left
Axle is on same diameter line.
Having the beneficial effect that acquired by the present invention is rigidly fixed by bearing pin between the present invention and annular entity, forms one
Overall, danger will not be produced because of the motion between suspender and workpiece in hoisting process, and structure is simple, workable；This
Bright be provided with four radially lifting pin-and-holes, thus large-scale annular workpieces can be processed after clamped one time processing on turn-miller
Put in place, decrease the labor content in suspender hole, improve work efficiency；Each bearing pin be adjusted in place by telescoping mechanism after again
Locking it is ensured that its in hoisting process will not play it is ensured that lifting safe and reliable.
Brief description
Fig. 1 is the structural front view of the present invention.
Fig. 2 is the upward view of the present invention.
Fig. 3 is the side view of the present invention.
Fig. 4 is the partial enlarged drawing in Fig. 2.
Fig. 5 is state diagram in hoisting process for the present invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As Figure 1-4, a kind of suspender for large-sized ring part lifting that the present embodiment provides includes lifting shoulder pole 1,
It is symmetrically arranged with bearing pin mounting seat 2 at the two ends of lifting shoulder pole 1, two radial direction bearing pins are installed on each bearing pin mounting seat 2
Hole, the centrage of each pin shaft hole intersects at a point, and each pin shaft hole is distributed on the circumference with this joining as the center of circle, and respectively
The joining of the centrage of individual pin shaft hole is located on the centrage of lifting shoulder pole 1, installs bearing pin 4, in pin in each pin shaft hole
One end that sleeve 3 is sleeved on bearing pin is correspondingly arranged on axle mounting seat 2, described sleeve 3 is fixedly installed in bearing pin mounting seat 2,
It is installed on the telescoping mechanism stretching for bearing pin between sleeve 3 and bearing pin 4.It is symmetrically arranged with the two ends of lifting shoulder pole and hang
Ear.
Described telescoping mechanism includes screw rod 5, and described screw rod 5 is threadeded with sleeve 3 and bearing pin 4 respectively, outer in screw rod
Termination is provided with spanner interface.
For the stability of workpiece when ensureing to lift, prevent workpiece from rocking or even turn on one's side, make two pins positioned at opposite slightly to the right or left
Axle 4 is on same diameter line.
Accordingly, in the corresponding design of the inner surface 4 radially lifting pin-and-hole of annular element, pin-and-hole can not affect the structure of ring body
With surface accuracy, should design on the insignificant finished surface of ring body, and because pin-and-hole is circumferentially distributed, therefore can be vertical
Milling lathe last time clamping processes, and is not required to repeated clamping.
It is attached fixing by four bearing pins between the shoulder pole 1 of suspender and annular element, by adjusting in bearing pin mounting seat 2
The position to control bearing pin for the screw rod 5 it is easy to be connected, meanwhile, bearing pin 4 uses double nut locked after having good positioning, and prevents
It loosens in hoisting process, causes danger.While ensureing that bearing pin semi-finals is spent, between bearing pin 4 also to be ensured and pin shaft hole
Axiality, in order to install.Also added gusset 6 to ensure the reliability lifting above bearing pin mounting seat simultaneously.
