Abstract
The utility model discloses a screwing device for a pipe fitting of a large pipe diameter and relates to a screwing device. The screwing device comprises a base, a chain wheel support, a chain wheel, lifting oil cylinders, a lifting table, a pipe fitting, carrier rollers, a carrier roller support, a holding chain and an electromotor, wherein a plurality of lifting oil cylinders are symmetrically arranged on the base in an inverted mode; the bottoms of the lifting oil cylinders are fixed with the lifting table; the lifting table is symmetrically provided with the carrier rollers; a holding chain is arranged around an outer link plate out of the carrier rollers; a friction lining is arranged in the outer link plate; the carrier rollers and the inner wall of the holding chain are provided with pipe fittings; the holding chain is meshed with the chain wheel; the chain wheel is arranged on the chain wheel support and is matched and connected with an axle by a key; and the axle is arranged on the base by the bearing and is connected with the electromotor by a key way at one end of the axle. The pipe fitting can be symmetrically stressed by the holding chain, the rotation is stable, the phenomena of flexural deformation is not easy to occur during screwing, and the chain line is added or removed to adapt to the change of the diameter of the machined pipe fitting.
Description
Technical field:
The utility model relates to a kind of device of screwing, and relates in particular to a kind of big caliber pipe fitting and screws device.
Background technology:
Tighten at present or when unclamping the pipe fitting that connects by screw thread pair, be to use anchor clamps (as clamping plate, chela etc.) to clamp pipe fitting earlier mostly, the rod member that is connected with anchor clamps by artificial rotation rotates pipe fitting relatively again.For the bigger pipe fitting of caliber, hand labor intensity is big and apply force limited, and production efficiency is low; Be subjected to the influence of grip size, machinable pipe fitting diameter is limited, and mechanical general rate is low; In addition, during artificial rotary tube piece, pipe fitting center, screw thread pair both sides can not guarantee point-blank, easily makes pipe fitting radially bend distortion.
The utility model content:
The purpose of this utility model provides big caliber pipe fitting and screws device, and it can make the stressed symmetry of pipe fitting by holding chain tightly, and rotation steadily is difficult for when screwing occuring bending and deformation; It can also be by increasing, subtract the chain link joint number with the increase of the diameter that adapts to processed pipe fitting or reduce.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises base, the chain wheeling support, sprocket wheel, hoist cylinder, lifting platform, pipe fitting, carrying roller, the carrying roller bearing, hold chain and motor tightly, a plurality of hoist cylinder symmetries are stood upside down and are arranged on the base, the bottom and the lifting platform of hoist cylinder are fixed, be symmetrically arranged with carrying roller on the lifting platform, carrying roller is provided with around outer plate outward and holds chain tightly, be provided with friction lining in the outer plate, on the carrying roller with hold the chain inwall tightly and be provided with pipe fitting, holding chain tightly is meshed with sprocket wheel, sprocket wheel is arranged on the chain wheeling support, sprocket wheel is connected by key and wheel shaft, wheel shaft is arranged on the base by bearing, and wheel shaft links to each other with motor by the keyway of one end.
The utility model is generally using, pipe fitting is placed on the carrying roller, open type is held chain tightly around pipe fitting, regulate and make it with sprocket wheel in same plane, by split pin its two ends connection is made it into closed circular, the piston rod of four hoist cylinders stretches out synchronously lifting platform is moved straight up, holds chain and sprocket engagement and chain tension tightly.When the chain rotation was held in the sprocket rotation drive tightly, friction lining had increased the maximum static friction force of holding chain and pipe fitting tightly, and pipe fitting is rotated along with holding moving of chain tightly, and the two pipe fittings that screw thread pair connects rotates in the opposite direction and slowly breaks away from; Lifting platform moves down, and it is lax to hold chain tightly, extracts split pin and makes and hold chain tightly and throw off, and can withdraw pipe fitting.Arrange because hoist cylinder stands upside down, realized that the liter slowly of lifting platform falls soon, guaranteed to hold tightly the steady tensioning of chain and lax fast, improved production efficiency.
The utility model has the advantages that it can make the stressed symmetry of pipe fitting by holding chain tightly, rotation steadily is difficult for when screwing occuring bending and deformation; It can also be by increasing, subtract the chain link joint number with the increase of the diameter that adapts to processed pipe fitting or reduce.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the B-B of Fig. 1 is to schematic diagram;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is for holding the structural representation of chain 9 tightly in the utility model.
The specific embodiment:
With reference to Fig. 1-4, this specific embodiment is by the following technical solutions: it comprises base 1, chain wheeling support 2, sprocket wheel 3, hoist cylinder 4, lifting platform 5, pipe fitting 6, carrying roller 7, carrying roller bearing 8, hold chain 9 and motor 10 tightly, a plurality of hoist cylinder 4 symmetries are stood upside down and are arranged on the base 1, the bottom of hoist cylinder 4 and lifting platform 5 are fixing, be symmetrically arranged with carrying roller 7 on the lifting platform 5, carrying roller 7 outer being provided with around outer plate 9-1 are held chain 9 tightly, be provided with friction lining 9-2 in the outer plate 9-1, on the carrying roller 7 with hold chain 9 inwalls tightly and be provided with pipe fitting 6, holding chain 9 tightly is meshed with sprocket wheel 3, sprocket wheel 3 is arranged on the chain wheeling support 2, sprocket wheel 3 is connected by key and wheel shaft, wheel shaft is arranged on the base 1 by bearing, and wheel shaft links to each other with motor 10 by the keyway of one end.
This specific embodiment is generally using, pipe fitting 6 is placed on the carrying roller 7, open type is held chain 9 tightly around pipe fitting 6, regulate and make it with sprocket wheel 3 in same plane, by split pin its two ends connection is made it into closed circular, the piston rod of four hoist cylinders 4 stretches out synchronously lifting platform 5 is moved straight up, holds chain 9 and sprocket wheel 3 engagement and chain tensions tightly.When chain 9 rotations were held in sprocket wheel 3 rotation drives tightly, friction lining 9-2 had increased the maximum static friction force of holding chain 9 and pipe fitting 6 tightly, and pipe fitting 6 is rotated along with holding moving of chain 9 tightly, and the two pipe fittings of screw thread pair connection rotates and slowly disengaging in the opposite direction; Lifting platform 4 moves down, and it is lax to hold chain 9 tightly, extracts split pin and makes and hold chain 9 tightly and throw off, and can withdraw pipe fitting 6.Because hoist cylinder 4 stands upside down and arranges, has realized that the liter slowly of lifting platform 5 falls soon, guaranteed to hold tightly the steady tensioning of chain 9 and lax fast, improved production efficiency.
The advantage of this specific embodiment is that it can make the stressed symmetry of pipe fitting by holding chain tightly, and rotation steadily is difficult for when screwing occuring bending and deformation; It can also be by increasing, subtract the chain link joint number with the increase of the diameter that adapts to processed pipe fitting or reduce.
