Description
Technical Field
The utility model belongs to the technical field of pressure vessel manufacturing tools, and particularly relates to an improved tool for accurately mounting and positioning a grid in a large-scale reactor.
Background
Early large reactors, such as ethylene oxide reactors, where the grid openings were prismatic, typically required mounting of the grid by means of prismatic locating pins. Referring to the attached drawing 1, the grid holes are prismatic, and the grid can be fixed and installed by passing a small prismatic positioning pin through the grid holes and rotating 180 degrees.
However, the prismatic grid is troublesome to manufacture, and people later design to change all grid holes into round holes, so that the prismatic positioning pin is convenient to machine and manufacture, and the original prismatic positioning pin cannot adapt to the manufacture of new equipment.
The prior ethylene oxide reactor barrel and the prior grid are not provided with a manhole or a large-diameter material inlet/outlet, so that personnel can not freely come in and go out of the inside of the supporting plate and the grid, and the personnel can only operate at the outer side in the assembling process, thereby influencing the working efficiency and the manufacturing quality.
Disclosure of Invention
The utility model aims to solve the problems and provides an improved tool for installing and positioning a reactor grid.
The main technical scheme of the utility model is as follows: the improved tool for installing and positioning the reactor grid is characterized by comprising an eccentric sleeve, an eccentric stud, a hollow pad and a nut, wherein the diameter of the excircle of the eccentric sleeve is matched with the diameters of holes in a lifting base plate and a supporting plate; the eccentric sleeve and the hollow pad are provided with eccentric through holes through which the eccentric studs penetrate, and the eccentric studs with the hook heads can freely rotate in the eccentric through holes; the nut can fasten the hollow pad, the hoisting base plate and the supporting plate through the hook head of the eccentric stud penetrating through the hollow pad and the eccentric sleeve.
Preferably, a gasket is arranged between the nut and the hollow pad.
Preferably, the diameter of the eccentric through hole is smaller than the radius of the eccentric sleeve, and the distance between the center line of the eccentric through hole and the center line of the eccentric sleeve is larger than the radius of the eccentric through hole.
Preferably, the length of the hook head is smaller than the diameter of the eccentric sleeve.
According to the improved tool, due to the ingenious design of the eccentric stud of the pass-band hook head, the grating can be stably conveyed into the fixed position of the cylinder body to be installed and positioned on the premise that the sufficient strength is provided to ensure safety.
The utility model is mainly used for installing and positioning the circular grid holes, is easy to operate, has higher performability and can greatly improve the working efficiency.

Detailed Description
The present invention will be described in detail below with reference to examples and the accompanying drawings.
Examples
Referring to the attached drawing 2, the improved tool for installing and positioning the large reactor grid mainly comprises an eccentric sleeve 5, an eccentric stud 1, a hollow pad 4 and a nut 2, wherein the diameter of the excircle of the eccentric sleeve 5 is matched with the diameters of holes in a lifting base plate 6 and a supporting plate 7, one end of the eccentric stud 1 is provided with a hook head, the length of the hook head is smaller than the diameters of the holes in the lifting base plate 6 and the supporting plate 7, and the diameter of the hollow pad 4 is larger than the diameters of the holes in the lifting base plate 6 and the supporting plate 7; the eccentric sleeve 5 and the hollow pad 4 are provided with eccentric through holes through which the eccentric studs 1 penetrate, and the eccentric studs 1 with hook heads can freely rotate in the eccentric through holes; the nut 2 can fasten the hollow pad 4, the hoisting base plate 6 and the supporting plate 7 through the hook head of the eccentric stud 1 penetrating through the hollow pad 4 and the eccentric sleeve 5.
In the embodiment, a gasket 3 is also arranged between the nut 2 and the hollow pad 4.
In the embodiment, the diameter of the eccentric through hole is smaller than the radius of the eccentric sleeve 5, and the distance between the center line of the eccentric through hole and the center line of the eccentric sleeve 5 is larger than the radius of the eccentric through hole; the length of the hook head of the eccentric stud 1 is smaller than the diameter of the eccentric sleeve.
When the tool is used in the embodiment, firstly, the hole of the lifting base plate 6 is aligned with the hole of the support plate 7, then the eccentric sleeve 5, the hollow pad 4 and the gasket 3 are threaded on the eccentric stud 1, the nut 2 is screwed, the eccentric stud 1 is firstly rotated to enable the hook head to point to the circle center of the eccentric sleeve 5 (the hook head position shown by a dotted line in the figure), the eccentric stud 1 is rotated to enable the hook head to hook the plane of the support plate (the hook head position shown by a solid line in the figure) after the eccentric stud 1 penetrates through the lifting base plate 6 and the support plate 7, and finally, the wrench is used for fixing the flat part of the eccentric stud 1 and fastening the nut 2, so that the fixing of the tool in the embodiment is finished. Otherwise, the nut 2 is loosened, the hook head of the eccentric stud 1 is rotated to point to the circle center of the eccentric sleeve 5, and then the tool of the embodiment can be taken out.
The improved tool for installing and positioning the reactor grid is mainly used for installing and positioning the circular grid holes, and is convenient and effective to use by an applicant. Ordinary workers can be skilled in operation without training, and a large amount of manpower and material resources are saved.
