Abstract
The utility model relates to a tube drawing out device, which relates to a clamping and disassembling tool which is suitable for drawing out tubes of the in-situ maintenance of a tubular heat exchanger. The utility model is composed of a sleeve barrel, a pipe slip, a connecting rod, a push rod, a draw rod, a lever and a supporting table. A core tube of a heat exchanger is gradually drawn out by the utility model form a tube plate of the heat exchanger by discontinuous manual operation. The utility model has the advantages of simple structure, small size, light weight, convenient operation, high safety and high work efficiency.
Description
Tube extractor of the present utility model belongs to the instrument of clamping, dismounting, particularly relates to a kind of Tube extractor of pipe heat exchanger.
When the site examining and repairing of pipe heat exchanger, extract damaged core pipe out and be absolutely necessary, normally vise pipe end and carry out tractive and finish with hoist engine.This method owing to there is not specific purpose tool, operate loaded down with trivial details, work efficiency is very low, and is also dangerous.
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, design a kind of rational in infrastructure, easy and simple to handle, safe in utilization, the special-purpose Tube extractor that work efficiency is high.
Tube extractor of the present utility model mainly is a kind of clamping, the extracting tool that utilizes the lever principle design.It is by a sleeve, and the slips with the sleeve coaxial line is arranged in sleeve, is provided with connecting rod, push rod, pull bar in the sleeve bilateral symmetry, and formations such as jaw lever and brace table.Sleeve middle and upper part sidewall symmetric position has can make push rod pass also two grooves of slidable upward opening.The bottom-hinged of connecting rod lower end and sleeve lateral wall, upper end and pull bar and push rod are hinged, and pull bar upper end is hinged with two arm ends of lever fork head respectively.The push rod end that stretches in the sleeve is provided with slips, and the slips inner surface has ratchet.There is the support arm of sector structure the lever below near the fork head place.Columniform brace table upper end has at least one plane to contact with the fan-shaped extrados of lever support arm, and the brace table lower end has at least one can insert the boss of working face pore.
Tube extractor of the present utility model is operated very convenient in use, earlier sleeve is aimed at the position that will extract pipe out, makes slips can vise the pipe end of being taken out.Again brace table upper end corresponding to the fan-shaped support arm of lever, the lower end boss inserts on the working face in another suitable pore, so promptly can begin to take out the pipe operation.Lift lever earlier, push rod and slips open simultaneously and move down.During depress lever, push rod promotes slips and has promptly vised the pipe end of being taken out again.Continue firmly to press down, pull bar affect push rod with slips with moving on the sleeve, the pipe that is vised also moves on simultaneously.Like this, lever is continuously lifted and presses down, pipe will be drawn out of at an easy rate.
That Tube extractor of the present utility model has is simple in structure, volume is little, in light weight, simple to operate, safe and reliable, work efficiency advantages of higher.
Figure of description is the structural representation of the utility model Tube extractor.
An exemplary embodiments of the utility model Tube extractor is: be symmetrical arranged two on the top of the sleeve (1) of a steel and push rod (4) passed and slidable groove (8); Be provided with in the sleeve and be fixed in the slips (2) that push rod end, inner surface have ratchet (9).Be arranged with an end in the outside of sleeve (1) and sleeve (1) is hinged, the other end and push rod (4), the hinged connecting rod (3) of pull bar (5).Two arm ends of the fork head (11) of the upper end of pull bar (5) and lever (6) are hinged.The bottom of lever (6) is provided with the support arm (10) of a sector structure near the fork head place.Brace table (7) be one cylindrical, the upper end is a shiny surface (12), there is the boss (13) that can insert the working face pore lower end.
Claims (7)
