Abstract

The invention relates to an automatic winding device for a hose pipe and in particular relates to an automatic winding device of a pneumatic conveying pipeline in a nodular cast iron pipe drawing device. A pipe drawing vehicle gas joint is fixed on a nodular cast iron pipe drawing vehicle; the pipe drawing vehicle gas joint is hermetically communicated with one end of a gas source exhaust pipe; the gas source exhaust pipe is wound on a wire spool; the other end of the gas source exhaust pipe is hermetically communicated with a gas joint of a bobbin; the wire spool is fixed on the bobbin; a sliding sleeve is fixed on the bobbin through a sealing device; a sliding sleeve gas joint is fixed on the sliding sleeve and is communicated with a gas source; the inner hole wall of the sliding sleeve is provided with a ventilation circular passage; the bobbin is internally provided with a gas passage; the gas passage and the ventilation circular passage are hermetically communicated with the gas joint of the bobbin; the bobbin is fixed on a bracket through a bearing seat; a rope wheel is coaxially fixed with the bobbin through a coupling; a steel wire rope winds on the rope wheel, and one end of the steel wire rope is fixed; and a counter weight is fixed at the other end of the steel wire rope. The automatic winding device of the pneumatic conveying pipeline has the advantages of simplicity in structure, low cost, low fault rate and high production efficiency.

Description

A kind of pneumatic carrier automatic winding apparatus

Technical field

The present invention relates to the automatic winding apparatus of pneumatic carrier in a kind of automatic hose winding device, particularly ductile iron pipe pipe drawing device.

Background technology

At present domestic and international nodular cast iron pipe efficient centrifugal machine pipe drawing device; The many elements in the inside adopt pneumatic; Pneumatic carrier is a lot, and is big at efficient centrifugal machine pipe drawing device relative movement distance, when pipe drawing device advances; Pneumatic carrier is stretched out naturally, and pneumatic carrier was rolled automatically when pipe drawing device was retreated.Traditional pneumatic carrier wind adopts wire spool, and clockwork spring is installed in the wire spool the inside; When pipe drawing device advanced, clockwork spring shrank, when pipe drawing device is retreated; Drive wire spool through clockwork spring and rotate, pneumatic carrier is rolled, adopt clockwork spring to drive; Fault rate is high, and the cost cost is high, influences rhythm of production.

Summary of the invention

In order to overcome the shortcoming of prior art, the present invention provides a kind of pneumatic carrier automatic winding apparatus, and it is simple in structure, and cost is low, and fault rate is low, and production efficiency is high.

The present invention solves the technical scheme that its technical matters takes: be fixed with tube drawing car gas connection on the ductile iron pipe tube drawing car, tube drawing car gas connection communicates with the end sealing of source of the gas freeing pipe, and the source of the gas freeing pipe is wrapped on the wire spool; The other end of source of the gas freeing pipe communicates with the sealing of roll gas connection; Described wire spool is fixed on the roll, on the roll through the fixing sliding sleeve of sealing arrangement, fixing sliding sleeve gas connection on the sliding sleeve; The sliding sleeve gas connection communicates with source of the gas; The ventilation circuit is arranged on the inner hole wall of sliding sleeve, air flue is arranged in the roll, air flue communicates with ventilation circuit and the sealing of roll gas connection; Described roll is fixed on the support through bearing seat, with roll through the coaxial fixedly rope sheave of drive coupling, be wound with steel rope and fixing one of which end on the rope sheave, the other end fixed weight of steel rope.

The present invention is simple in structure, and cost is low, and fault rate is low, and production efficiency is high.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is a structural representation of the present invention;

Fig. 2 for the A among Fig. 1 of the present invention to view;

Fig. 3 is the B place enlarged drawing among Fig. 2 of the present invention.

The specific embodiment

Shown in accompanying drawing, be fixed with tube drawing car gas connection 2 on the ductile iron pipe tube drawing car 1, tube drawing car gas connection 2 communicates with the end sealing of source of the gas freeing pipe 3; Source of the gas freeing pipe 3 is wrapped on the wire spool 17, and the other end of source of the gas freeing pipe 3 communicates with 23 sealings of roll gas connection, and described wire spool 17 is fixed on the roll 18; Pass through fixedly sliding sleeve 16 of sealing arrangement 20 on the roll 18; Fixing sliding sleeve gas connection 19 on the sliding sleeve 16, sliding sleeve gas connection 19 communicates with source of the gas, and ventilation circuit 21 is arranged on the inner hole wall of sliding sleeve 16; Air flue 22 is arranged on the roll 18, and air flue 22 communicates with

ventilation circuit

21 and 23 sealings of roll gas connection; Described roll 18 is fixed on the support 4 through bearing seat, with roll 18 through drive coupling 15 coaxial fixedly rope sheaves 13, be wound with steel rope 5 and fixing one of which end on the rope sheave 13, the other end fixed weight 11 of steel rope 5.

Be fixed with fixed pulley group 7 and running block 10 between described steel rope 5 and the counterweight 11; Fixed pulley group 7 is separately fixed on fixed pulley frame 6 and the movable pulley frame 9 with running block 10; Fixed pulley group 7 and the running block on the movable pulley frame 9 10 that steel rope 5 is walked around on the fixed pulley frame 6 are fixing with the hook 8 that is fixed on the fixed pulley frame 6, the lower end fixed weight 11 of movable pulley frame 9.

Described wire spool 17 and sliding sleeve 16 have many groups, to satisfy the requirement of tolerance.

The tube drawing car advances and drives source of the gas freeing pipe 3 and advance, and wire spool 17 rotates, and wire spool 17 drives rope sheaves 13 and rotates through roll 18, coupler 15, and counterweight 11 rises.When plyer was retreated, counterweight 11 drove rope sheave 13 backward rotation because action of gravity descends, wire spool 17 backward rotation, and source of the gas freeing pipe 3 is wound on the wire spool 17 automatically.
