Abstract
The invention discloses a circular framework sling. The circular framework sling comprises a framework, a pressing block and bolts. The framework is a circular rigid member. The periphery of the framework is provided uniformly with at least three radial screw holes for bolt installation. The top of the outer wall of the framework is connected to a hanging bracket. A hanging ring is arranged at the middle of the top of the hanging bracket. The pressing block is located in the framework. An outer convex part of the pressing block has a clamping connection with ends of bolts to form a radial linkage structure. The circular framework sling can loads and unloads a workpiece at a nearby location. Through adopting a high-reliable screw type clamping structure, the circular framework sling can guarantee safety of loading and unloading operation, and reduce labor intensity. Collision between a workpiece and a machine tool in lifting loading can be avoided through shielding effects of the framework which is located in the external and is circular. The circular framework sling is particularly suitable for lifting loading in mass production of large gears and disc-shaped parts.
Description
Technical field
The present invention relates to a kind of mechanical suspender, specifically, the present invention relates to a kind of annular frame suspender that lifts by crane large-scale disc-like gear.
Background technology
The supporting spiral bevel gear diameter of heavy wrecker truck reaches hundreds of millimeters, and blank weighs several ten kilograms, and the loading and unloading operation in mechanical processing process is assisted to implement by auxiliary worker usually.Although prior art is easy, can effectively organize production.But during production in enormous quantities, artificial loading and unloading operation manifests practical problemss such as labour intensity is big, work efficiency is low, poor stability.In addition, many people loading and unloading operation is particular about harmony, coordinates bad easy generation safety problem.Generally speaking, prior art is not suitable for producing in enormous quantities and uses.
Summary of the invention
The present invention is primarily aimed at the deficiency of prior art, propose a kind of simple in structure, loading and unloading easily, the annular frame suspender of lifting safety.
The present invention realizes technical goal through following technical proposals.
The annular frame suspender, it is made up of framework, briquetting and bolt.Said framework is the annular arrangement rigid member, is uniformly distributed with at least 3 radially screws on the circumference, framework outer wall top captive joint rectangle flap seat, and the flap seat top is provided with suspension ring between two parties.Ecto-entad screws in the radially screw of said bolt from the framework outer wall.Its improvements are: said briquetting is the plane circular arc-like block, and its lateral cross section is a dihedral, and briquetting male part and bolt end screens connect and compose radially linkage structure.
In the said structure, briquetting seal face radius R
2Value equals the radius value of workpiece, radius of circle R in the framework
1Be worth little 15mm～25mm.The material of briquetting is non-metals commonly used.
The present invention compared with prior art has following good effect:
1, the screw clamp locking structure is simple, and is easy to manufacture;
2, mechanical hoisting good reliability, charge and discharge operations safety, labour intensity is low;
3, external annular frame has the protective case effect, and generation workpiece and lathe collide with when avoiding lifting.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
According to accompanying drawing and combine embodiment, the present invention is described further below.
Annular frame suspender shown in Figure 1, it is made up of framework 1, briquetting 2 and bolt 3.Said framework 1 is the annular arrangement rigid member, is uniformly distributed with at least 3 radially screws on the circumference, framework 1 outer wall top captive joint rectangle flap seat 3.2, and flap seat 3.2 tops are provided with suspension ring 3.1 between two parties.Ecto-entad screws in the radially screw of said bolt 3 from framework 1 outer wall.Said briquetting 2 is the plane circular arc-like block, and its lateral cross section is a dihedral, and the male part of briquetting 2 and bolt 3 termination screens connect and compose radially linkage structure.The workpiece that lifts in this example is Shan vapour 450 spiral bevel gears, and radius is 225mm, briquetting 2 seal face radius Rs
2Identical with the workpiece radius value.Briquetting 2 is built in the framework 1 and with bolt 3 radiai adjustment degrees of tightness, so briquetting 2 seal face radius Rs
2Less than radius of circle R in the framework 1
1, R in the present embodiment
1Value is 250mm.Less relatively in the present embodiment because of the workpiece size of lifting, only establish 3 screws that are uniformly distributed with on framework 1 circumference and just can satisfy the safety jaw reload request.Briquetting 2 is used the copper material manufacturing, avoids on workpiece, staying impression.
Workpiece loading and unloading nearby during practical application of the present invention.The position of pressing 3 briquettings 2 of excircle of workpiece size coarse adjustment earlier during installation; Wherein 1 briquetting 2 outer moving stays installing space again; Treat the briquetting 2 that workpiece is in place and screws and move outward; Make it the radial compaction workpiece, hook suspension ring 3.1 with lifting appliance then and be transported to the machinework position, unscrew 1 bolt 3 and just can take off workpiece.Otherwise operation, but the workpiece that the handling of slave Working position has been processed is to the position of storing in a warehouse.Whole charge and discharge operations safety, labour intensity is low, and external annular frame 1 has the protective case effect, when avoiding lifting workpiece takes place and lathe collides with.
