Abstract
The utility model relates to a movable clip for assembling big flanges. The clip comprises a pair of scissor forks which are arranged in a crossing way and are articulated together, one end of the scissor forks is used for arranging a lifting part, the other end thereof is used for arranging a holding part; the holding part comprises a pair of roller bracket assemblies which are arranged correspondingly for holding flanges to be assembled. The flanges are only arranged vertically on the ground, then the movable clip is lifted above the flanges, a hoisting tool moves downwards; after a movable roller of the holding part of the movable clip is contacted with an excircle arc surface of the flange, the roller slides downwards along the excircle path by self weight until sliding in place, a self-locking pin is inserted, then the flanges are lifted, thus leading the flange threads to be aligned with pipe orifice threads, the flange is assembled rotationally by being toggled by hands. When the flanges are assembled, the hoisting tool moves downwards, at the moment, the movable clip is mot limited by clamping force, the self-locking pin is pulled out, the hoisting tool moves upwards, the lifting movable clip is automatically separated from the flanges, thus finishing the whole work that the flanges are screwed in.
Description
Technical field
The utility model relates to mechanical assembly flange parts, refers in particular to a kind of big flange assembling activity folder.
Background technology
The method of pipe flange assembling at present is that the small size flange manually directly assembles with hand, and large-sized flange is heavier, limited by the place, is difficult to assembling, the workman operates dangerous, inefficiency.Threaded flange is along with the increase of high-pressure pipe latus rectum, and its volume and weight also enlarges markedly.As the threaded flange of PN32 DN300, weight reaches 324kg, and external diameter is φ 720mm, and out-of-date methods have been difficult to satisfy the needs of the big flange assembling of pipeline.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of laborsaving, safe, big flange assembling activity folder efficiently is provided.
The utility model comprises:
An arranged in a crossed manner and hinged secondary scissors fork, an end of scissors fork is used to be provided with lifting part, and the other end is used to be provided with hold assembly;
Described hold assembly comprises a secondary corresponding rolling stand assembly that is provided with, and is used for flange to be assembled by the clamping of rolling stand assembly.
Advantage of the present utility model and beneficial effect:
The utility model is simple to operate, quick, laborsaving, safety, flange need only be stood up on the ground (keeping flat feasible equally), then live splint is hung the flange top, live splint and flange are remained on the line of centers, lifting gear down moves, behind the movable drum engagement flange exterior arc surface of live splint hold assembly, make downglide motion by deadweight along flange cylindrical track, after downslide puts in place, insert self-lock pin, can lift by crane flange, flange screw thread and mouth of pipe screw thread are aligned, stir flange rotation assembling with hand.After flange assembled, lifting gear was descending, and at this moment, live splint is not subjected to the constraint of gripping power, extracted self-lock pin out, and lifting gear is up, and the live splint of slinging breaks away from flange automatically, finishes the whole work that are screwed into flange.
Description of drawings
Fig. 1 is the utility model system construction drawing
Fig. 2 is Fig. 1 part sectional view
Fig. 3 is the utility model working state figure
The specific embodiment
By Fig. 1 to 3 as can be known, the utility model comprises:
An arranged in a crossed manner and hinged secondary scissors fork 4, an end of scissors fork 4 is used to be provided with lifting part, and the other end is used to be provided with hold assembly;
Described hold assembly comprises a secondary corresponding rolling stand assembly 1 that is provided with, and is used for flange to be assembled by 1 clamping of rolling stand assembly.
Principle of work of the present utility model:
The flange that assembles when needs erects on ground, be flange exterior arc surface when landing,, block flange both sides exterior arc surface with four cylinders of the rolling stand parts of floating holder with the lifting gear floating holder of slinging, insert self-lock pin, can lift by crane the place of needs assembling.When flange lies in ground, when promptly flange one side plane lands, need flange gasket is played certain altitude (rolling stand blocks flange requisite space height), live splint is hung the flange top, the swing roller bracket component, the level of making it is blocked flange, after card is good, last self-lock pin, can lift by crane, during assembly flange, the rotatable drum bracket component, flange screw thread and mouth of pipe screw thread are aligned, so that assembling.
The rotating mechanism of forming by cylinder 14, drum shaft 15, deep groove ball bearing 13, rolling stand 16.After flange screw thread and mouth of pipe screw thread align, because self-lock pin 5 inserted, there be the sling flange screw thread mouth of live splint clamping and the screw thread mouth of pipe fitting of certain free gap, lifting gear to align the location during cylinder 14 clamping flanges, artificial rotary flange is finished the fitting work of flange.
After flange assembles, the scissors fork of lifting live splint is not subjected to the constraint of gripping power, extracts self-lock pin 5 out, the lifting gear flange live splint upward movement of slinging breaks away from flange automatically, finishes the whole work that are screwed into flange.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; do not breaking away under the preceding topic of the utility model design philosophy; engineering staff make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
