Abstract

The utility model discloses a counterflow pipe bundle welding rotary table machine for a boiler, comprising lifting frames which are symmetrically arranged. The utility model is characterized in that each lifting frame is provided with a lifting box which can move along the lifting frame; one side of each lifting box is fixed with a platform; a motor and a speed reducer are arranged on the platform; the output shaft end of the speed reducer is provided with a tire holder; the upper end and the lower end of the lifting frame are provided with pulleys; one end of a steel wire is wound with the roller of a hoister, and the other end is fixed on the lifting box through winding the pulleys. The utility model can be used for the counterflow pipe bundle welding of various boilers.

Description

Boiler counterflow pipe bundle welding rotary table machine

The utility model belongs to a kind of clamping device, relates to a kind of boiler convection bank welding turntable machine.

In boiler industry, the welding of boiler convection bank is that requirement is very strict, because the tubing of convection bank is steel, and will it need be overturn back and forth from different perspectives to its welding, so be difficult to finish by manpower.In the prior art, the welding of convection bank needs people and crane to work in coordination, and every welding one array of pipes just needs lifting once, just not only takes a lot of work but also require great effort when working like this, also is difficult to guarantee welding precision.

The purpose of this utility model provides a kind of can increasing work efficiency, and saves manpower, guarantees welding quality, can standardized production, and can satisfy various boiler tube bundles are welded, finish the boiler convection bank welding turntable machine of different process requirement.

To achieve these goals, the utility model adopts the hoisting rack of two symmetric arrangement, and an elevator chamber that can move along hoisting rack is all arranged on each hoisting rack; Be fixed with a platform in elevator chamber one side, motor and reductor are installed on platform; The output axle head of reductor is equipped with a moulding bed; In the hoisting rack top and bottom pulley is arranged all, steel wire rope one end and hoist engine cylinder twine, and after the other end is walked around assembly pulley, are fixed on the pulley bracket.

The utility model has the advantages that: simple in structure, clamping workpiece is convenient, and moulding bed can drive workpiece and stop being hung in differing heights and angle, can increase work efficiency greatly.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model.

Describe and provide embodiment in detail below in conjunction with accompanying drawing.

As shown in drawings, the utility model is a symmetric arrangement, respectively have in both sides a hoisting rack 2 and 2 ', an elevator chamber 4 is all arranged on each hoisting rack, said elevator chamber 4 is can be on hoisting rack upper and lower to be moved; Be fixed with a platform in elevator chamber one side, be fixed with motor 1 and reductor 3 on platform, be connected with a moulding bed 6 at the output axle head of reductor, having on the moulding bed 6 to have clip 5 along the forward and backward mobile telescopic arm 10 of moulding bed on telescopic arm 10.At hoisting rack upper end, lower end and middle part one row's pulley is arranged respectively, steel wire rope 7 and 7 ' one ends are walked around the cylinder 8 of pulley and hoist engine, and with being wrapped on the cylinder.During operation, at first two collection casees 9 with convection bank are fixed on the clip 5 of telescopic arm, adjust distance, on convection tube insertion and the corresponding pore of collection case, allow then the cylinder 8 of hoist engine drive steel wire ropes 7 and 7 ', thereby drive elevator chamber 4 and be elevated to proper height along hoisting rack, start motor 1 then, two motor synchronous are rotated, drive moulding bed 6 and forward certain angle to, then to the tube bank welding, because moulding bed 6 can be in arbitrarily angled upset, so the convection bank on the moulding bed is also turning to any angle, so just can be easily to the tube bank welding.

Claims

1, a kind of boiler convection bank welding turntable machine comprises it is characterized in that the hoisting rack of symmetric arrangement: an elevator chamber that can move along hoisting rack is all arranged on each hoisting rack; Side at each elevator chamber all is fixed with a platform, and motor and reductor are arranged on platform, at the output axle head of reductor a moulding bed is installed; All there is pulley top and bottom at hoisting rack, and the cylinder of steel wire rope one end and hoist engine twines, and after the other end is walked around pulley, is fixed on the elevator chamber.
