Description
Technical field
The utility model relates to suspender fields, and in particular to a kind of large-sized end enclosure single-point boom hoisting.
Background technique
End socket of the outer diameter greater than 1m is the main pressurized element in large-scale hydrogenator.To meet equipment requirement,
End socket needs to carry out restorability heat treatment to it after heat stamping and shaping.Property heat treatment is divided into normalizing, quenching, tempering three
The lifting in stage, whole process is completed by special hanger " two o'clock is hung ".It is deformed for end socket caused by reduction " two o'clock is hung ", in property
It is control end socket port sizes in technique, it is desirable that in end socket end face, welding equipment anti-deformation tool is as shown in Figure 1 before capable of being heat-treated.
Property heat treatment is divided into normalizing, quenching, tempering three phases, and the lifting of whole process is all made of suspender " two o'clock is hung "
It completes.As shown in Figure 1, needing to exist in the edge of end socket 100 welding buffering ring 120 and reinforcing rib 130, end socket 100 before lifting
Normalizing temperature (about 950 DEG C) is come out of the stove, and hook is placed in 120 lower surface of buffering ring before lifting, the position of symmetrical 180 degree passes through " two
Point is hung " it is hung to quenching tank, end socket stress condition is as shown in figure 1 shown in F1, F2 at this time.
It can be seen from the figure that 100 port of end socket in lift hook position by upward drawing force, 100 self gravity of end socket to
Under, end socket 100 completes the lifting of quenching treatment under the action of this is to equilibrant force.If at normal temperature, this lifting method is
It is feasible, plastic deformation will not be generated to end socket size.But 100 temperature of end socket is up to 950 DEG C or more at this time, the tension of material
Intensity and yield strength seriously reduce.Therefore, the drawing force suffered by the end socket 100 is greater than the allowable stress of 100 material of end socket at this time
When, it will lead to end socket 100 and generate plastic deformation.If 100 deformation of end socket is larger, it cannot be guaranteed end socket in following process
100 corresponding size requirement, it is at high cost greatly to reprocess difficulty, while also resulting in biggish production cycle waste.
As it can be seen that necessary redesign new-type method and suspender, accelerate manufacturing schedule while reducing cost consumption,
Reach good using effect during end socket performance, reduces labor intensity.

Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figures 2 and 3, the large-sized end enclosure single-point boom hoisting of the utility model, including pulling plate 1 and hanging plate, it is described
Pulling plate 1 is vertically arranged, and the upper end of pulling plate 1 is provided with hoisting structure 4.The hanging plate includes connecting plate 2 and support plate 3, described
Connecting plate 2 is fixed at the middle position of support plate 3, and connecting plate 2 is rotationally connected with the lower end of pulling plate 1.
Pulling plate 1 be strip plate, hoisting structure 4 be used for by present apparatus integral installation workshop driving.Support plate 3
Also elongated, it is used to support end socket 100, bears the weight of end socket 100, connecting plate 2 is used to support plate 3 being installed to pulling plate 1
On, connecting plate 2 is rotationally connected with the lower end of pulling plate 1, i.e., connecting plate 2 and support plate 3 can make to prop up in vertical rotation in surface
Fagging 3 turns to vertical position from horizontal position, or turns to horizontal position, the width of support plate 3 and pulling plate 1 from vertical position
Degree size will meet: when support plate 3 turns to vertical position from horizontal position, the overall width of support plate 3 and pulling plate 1 is less than envelope
The internal diameter in the end socket hole 110 at first 100 top, guarantees that pulling plate 1 and support plate 3 can pass through end socket hole 110；The length of support plate 3
Meet: when support plate 3 turns to horizontal position from vertical position, the length of support plate 3 is greater than the internal diameter in end socket hole 110, makes
The long surface support of support plate 3 lives the medial surface of end socket 100.
When using the present apparatus, pulling plate 1 is fixed in driving using hoisting structure 4, starting driving is moved to the present apparatus
The surface of end socket 100, then rotational support plate 3 to vertical position, then support plate 3 and pulling plate 1 are transferred, keep support plate 3 complete
Portion passes through end socket hole 110, as shown in figure 4, support plate 3 is turned to horizontal position again, promotes pulling plate 1, support plate 3 then up
Upper surface is contacted with end socket 100 to sling end socket 100, as shown in Figure 5.
Connecting plate 2 can be used any one existing articulated structure and be connected with the lower end of pulling plate 1, it is preferred that the pulling plate 1
Fluted and through-going recess pin shaft 5 is arranged in lower end, and the connecting plate 2 is provided with positioning through hole, and the upper end of connecting plate 2 is protruded into
In groove, the pin shaft 5 is located in positioning through hole and is rotatably assorted with positioning through hole.The connection type of this structure can make to draw
The pulling force that plate 1 is subject to is more uniform, is conducive to the bearing capacity for improving device, guarantees the stability of device.
When use can direct rotational support plate 3 manually, it is inconvenient for operation but since space limits, therefore, in the support
The end of plate 3 is provided with pulling eye 6, specifically, pulling eye 6 can be arranged in one end of support plate 3, can also be the two of support plate 3
End setting pulling eye 6.In use, steel cable is passed through pulling eye 6, wirerope is then pulled, support plate 3 can be pulled to turn upwards
It is dynamic；After support plate 3 passes through end socket hole 110, wirerope is unclamped, support plate 3 can be made to automatically rotate to horizontal position, is operated non-
It is often convenient.
The connecting plate 2 and support plate 3 are integrally formed, and structural strength is high, and simpler convenience when processing.
Hoisting structure 4 can be hook, through-hole etc., it is preferred that the hoisting structure 4 is lifting lug.
3 upper surface of support plate of 2 two sides of connecting plate is set as the arcwall face cooperated with 100 medial surface of end socket, energy
Enough increase the contact area between connecting plate 2 and end socket 100, reduces the active force that end socket 100 is subject to, reduce the risk of deformation.
Further, the hanging plate is 2.25Cr1-Mo material.Boom hoisting is simulated using ANSYS Finite Element Simulation Software
Force-bearing situation hanging plate distribution of force cloud atlas as shown in FIG. 6 is obtained by the analytical calculation of software, it can be seen from the figure that
The maximum stress of hanging plate is present in two-arm radiused surface, and stress maximum value is 213.53Mpa, this value is hanging plate material institute energy
The maximum permissible stress of permission.Therefore, the considerations of when selecting its material according to this result and high temperature, finally selects
2.25Cr1-Mo material, in retest of materials mechanical properties value, 425 degree of high-temperature yield strengths are 375MPa, divided by safety coefficient
It is 250MPa that its allowable stress is obtained after 1.5, therefore the design structure meets requirement.
The features such as hoisting tool of the utility model has of simple structure and strong practicability, is convenient for operation, operator can be remote
Distance, the lifting being quickly accomplished under end socket heat treatment high temperature, improve the lifting efficiency of end socket, it is strong to greatly reduce labour
Degree.Solve the puzzlement big difficulty of container products manufacturing schedule one for a long time, save the manufacture of a large amount of anti-deformation tool at
This, makes end socket heat-treatment distortion be effectively controlled.
