Abstract

The utility model belongs to pipeline dredging tool which is used to dredge the bent pipeline, in particular a cheap dredger of the sewer of the pumping toilet. The utility model is composed of a wooden bar, and iron chain pieces. Because each chain piece is provided with a limiter which is used to limit the rotating range of the chain piece, the dredger can turn along the wall of the pipeline. The dredger can directly contact with the blockage in the bent pipeline, or can propel in or draw out by using a barb, etc., the blockage. Therefore, the efficacy of the dredging is improved.

Description

Chain dredging tool for curved pipe

The utility model belongs to pipe dredging tool.

The mediation work of various crooked pipelines is all very difficult.For example with the common tool leather cup dredge the Toilet that draws water or the crooked sewer of sewage reservoir, be to inhale obturator through water, air pressure by leather cup, often do not prove effective, get half the result with twice the effort.

This Chain formula dredging device can enter in the pipe and turn round along pipeline, directly contacts bend pipe internal congestion thing, or advances or utilize down Hook etc. to pull out, draw broken obturator, thereby improves effect greatly.

As Fig. 1, Fig. 2, by axle (form by a string by the Chain sheet (2) that 3), Huo Hinge Chain or Qiu Mian Hinge Chain (18) rotate for this Chain formula dredging device.For making this string Chain sheet should limit the scope of each Chain sheet along duct wall propellings of turning round with respect to adjacent Chain sheet rotation:

At first, above-mentioned slewing area should be limited in and can not turned back in pipeline in the dredging device termination; Following this layer meaning of pro describing: above-mentioned slewing area should be limited in and make the Chain sheet termination of turning back to the line of the Chain sheet points outside that forms the limit relative with it long (a of Fig. 1, b, c, d, e simplelyr ...) greater than the interior diameter of pipeline.If each Chain sheet is shorter, and the Chain sheet relatively rotates angle and exceeds this scope in twos, and Chain sheet termination runs into obturator (8) in pipe, just might turn back, and can not push ahead.When the length and width of Chain sheet or thickness were suitable, the slewing area that can select the Chain sheet was to satisfy this point.

Consider from another point of view, this slewing area should make the longitudinal centre line included angle A of adjacent in twos Chain sheet to turn to and be equal to or greater than angle C by being equal to or less than angle B again, angle B by in the mediation process, this two adjacent Chain sheet the angle of the broken line of the segmental arc of pipeline maximum curvature of process or minimum angles and they when external, two Chain sheet longitudinal centre lines, angle C then be above-mentioned through the piping minimum curvature segmental arc or the angle of the broken line of maximum angle and they when external, two Chain sheet longitudinal centre lines.For the thrust that back one Chain sheet is given produces enough vertical component on last Chain sheet, to overcome tube wall frictional force, above-mentioned included angle A again preferably can be greater than right angle (under the condition smaller or equal to included angle B, increasing to the approaching then component of 180 degree); For the bend pipe of various curvature, as long as the length that each Chain sheet is got is not long, perhaps use length-adjustable Chain sheet (as (21) of Fig. 4), can satisfy this point.

For achieving the above object, can be provided with and to limit each Chain sheet with respect to adjacent Chain sheet slewing area bridle by above-mentioned requirements, this bridle can be arranged on the parts (10,11) of similar block on each Chain sheet, and employing connects (10) or welding or spiral shell Pattern with Chain sheet and is connected (11) or screw-nut connection forms such as (15); The special-purpose member (16,19,20) that this bridle also can separate with the Chain sheet; Also the Chain sheet same on the whole through punching press or cutting or casting or injection of plastic moulding, with the plane of rotation formation certain angle of Chain sheet, vertical part (6,12～14,17～19) preferably.

The bridle of this restriction slewing area also can be made into can go up the parts (for example (20) of Fig. 3) of change permanent position at Chain sheet (2), in order to regulate the scope that relatively rotates of each adjacent Chain sheet, to adapt to the crooked pipeline of different curvature or angle.

The also available circle of Chain sheet cross section waits other form, and the structure of bridle and style also can have various ways, is not limited only to Fig. 1～4 the cited case.

For plain bending pipeline (its center line is in one plane), the dredging device that the Chain sheet that available energy connects at the axle (3) or the Hinge Chain of one or two direction rotation is formed; For curvature of space pipeline (its center line not in one plane bend pipe), the dredging device that available energy is formed at the Chain sheet of the ball face Hinge Chain (18) of multi-direction rotation or universal coupling connections such as (19).

Dao Hook (5) has as the effect of pulling out or drawing broken obturator; The dredging device termination also can be made into scrapes rake (as (22) of Fig. 5, desirable draw in when advancing as umbrella shape, withdraw from and open), in order to scrape off the accumulations on the tube wall.When the termination being made Luo Xuan Hinge cutter shape or claw-like (as (23) of Fig. 6), the dredging device that uses the Chain sheet of two ball face Hinge Chain that add pin or universal coupling connections such as (19) to be formed; And loads onto hand crank or connects rotary power at Chain sheet tail end, this dredging device promptly has along bend pipe rotation propulsion capability; sharp with the softer obturator of Hinge cutter cutting quality, or pulls out after utilizing pawl to twine the fibre object such as wiring that are blocked in the pipe; For making each Chain sheet rotation good, the longitudinal centre line included angle A of adjacent in twos Chain sheet should be greater than 135 degree, and this moment, available flexible Chain leaf length for example used the Chain sheet (as (21) of Fig. 4) with adjustable length structure to adapt to the curvature of different pipelines.Have down Hook or scrape the also available Luo Pattern of parts of rake, Huo Hinge cutter shape or claw-like or joint etc. is connected the termination of dredging device.

The applicant thinks, the best form of the Chain formula dredging device of the Toilet institute sewer that is used to draw water as shown in Figure 1.Therefore sewer has straight-run of pipe (7), so aforesaid angle C is 180 degree, and dredging device can connect one section straight excellent (9), and this straight rod can be wood, bamboo or plastic pipe.The close straight excellent back a few joint Chain sheets of cause last spill of process in the mediation process is bent (1), is bent (4) without back one convex, so these a few joint Chain sheets only need be made one-sided the relatively rotating of energy; Former joints then need bilateral to relatively rotate.Available steel sheet of each Chain sheet or iron plate are through the punch ram moulding, and is antirust in the And plating, and the Chain sheet connects bunchiness through the nail.
