Abstract

The utility model relates to a pipe dirt scaler which comprises a bracket, a cutter head, a bracing ring and a coupling shaft, wherein, the cutter head is arranged on the bracket, and a cutter blade is arranged on the cutter head. The front part of the bracket is provided with the coupling shaft, and the bracing ring is fixed on the coupling shaft by a bolt. The bracket is horizontally provided with a slide rod, and a slide tensioner is arranged on the slide bar. The tensioner is hinged with the cutter head which is plugged into the bracket. The other end of the slide bar is connected with a linking shaft through a pin. Because of the adoption of the movable cutter head, the turn of a cutter adopts cross connection which can not rotate. In addition, an ultrasonic positioner is arranged on the cutter. The utility model has the advantages of simple and compact structure, convenient use, long maintenance period, accurate positioning and reliable work.

Description

Pig

The utility model belongs to industrial apparatus for eliminating sludge in pipe, specifically is a kind of pig.

Mostly present industrial apparatus for eliminating sludge in pipe is fixed installation tool rest and blade on support, and by universal ball end the elastic support circle is installed in the front portion of support, and the descaler of this structure has existed following what time not enough in the application of reality:

1, cutter is the hilted broadsword cutting, and cutting is low with crashing rate.

2, cutter adjustment precision is low, and it is big to adjust workload, causes protruding cutter easily, so that damage cutter and support.

3, ball head universal connects because of scale removal partial rotation in the cutter running, fragile cutter.

4, equipment does not have positioning work piece, is difficult to give when cutter causes card pipe phenomenon the cutter positioning.

It is a kind of simple and compact for structure, easy to use that the purpose of this utility model is to provide, and maintenance period is long, accurate positioning, the pig of reliable operation.

The utility model is achieved through the following technical solutions:

It is a kind of pig, comprise support, tool rest, bracing ring and shaft coupling, tool rest is installed on support, blade is installed on the tool rest, and shaft coupling is installed in the front portion of support, uses the bolt bracing ring on shaft coupling, it is characterized in that support level installation sliding bar, suit slip stretcher on sliding bar, stretcher is hinged sliding bar the other end pin joint couple axle with the tool rest that is inserted on the support.

Described slip stretcher is made up of join power dish, Returnning spring and regulating lever that cover installs on the sliding bar, joins suit Returnning spring on the sliding bar of power dish inboard, joins the hinged regulating lever of power dish periphery, and the other end and the tool rest of regulating lever are hinged.

Described sliding bar end connects an above couple axle successively, the connecting part suit Returnning spring of couple axle.

Lodar is installed in the described support.

Symmetry is installed one group with upper cutter head on the described support.

Staggered side by side installation a slice is with upper cutting blade on the described tool rest.

Between the bracing ring on the couple axle that described sliding bar end connects successively ash-stopping ring is installed.

The utility model compared with prior art owing to used movable tool rest instead, turning to of cutter adopted the universal joint cross that can not rotate to connect, and installed lodar on descaler additional, so have the following advantages:

1, simple and compact for structure, easy to use.

2, maintenance period is long, accurate positioning, reliable operation.

Describe in further detail below in conjunction with accompanying drawing:

Fig. 1: the utility model example structure schematic representation.

Among the figure: 1 composite blade, 2 tool rests, 3 supports, 4 regulating levers, 5 are joined power dish, 6 sliding bars, 7,8 Returnning springs, 9 bracing rings, 10 positioning work pieces, 11 universal joint crosss, 12 retaining ash covers

In use, the position of joining power dish 5 earlier according to the caliber of pipeline by the nut adjustment of joining power dish 5 front portions, make and join power dish 5 before sliding bar 6 pressed home springs 7, move the back, drive tool rest 2 along moving on the sliding-groove on the support or down by regulating lever 4 again, until with till the caliber of pipeline is suitable mutually, then this descaler is forwardly put into pipeline with bracing ring 9, open water valve, then promoting bracing ring 9 under the effect of hydraulic pressure advances, 1 pair of tube wall of composite blade cuts when descaler advances, scale removal, because of many group composite blades being installed in the periphery symmetry of support 3, so to dirty remove clean of tube wall, thoroughly, when descaler advances to the crooked position of pipeline, under the effect of universal joint cross shaft coupling 11, just can drive the support 3 and smooth successively the bend pipe of tool rest 2 of bracing ring 9 back by pipeline, and under the effect of Returnning spring 8, the universal joint cross 11 that links is automatically reset rapidly, because of support 3 and bracing ring 9 are to connect by the universal joint cross 11 that can not rotate arbitrarily, so solved because of the descaler cutter with the preceding of bracing ring 9 and then rotate, damage the problem of cutter easily, when when descaler advances process in pipeline in, being stuck, by the positioning work piece of installing on the descaler 10, just can find the position of card pipe easily, take out descaler so that take measures, retaining ash cover 12 between two bracing rings 9, can play descaler and prevent that in the course of the work foreign material from entering the connection place of universal joint cross 11, influence the rotation flexibility of universal joint cross 11.
