It includes: the fixed bolster, a permanent magnet, the telescopic link, support piece, the 2nd permanent magnet and gyro wheel, a permanent magnet rigid coupling is on the fixed bolster, telescopic link bottom and fixed bolster looks rigid coupling, top and support piece looks rigid coupling, the gyro wheel is articulated mutually with support piece, the last cell body that is used for the 2nd permanent magnet of holding that is formed with of support piece, the 2nd permanent magnet and a permanent magnet one -to -one and homopolar relative, permanent magnet with interconnect, the telescopic link, support piece, the 2nd permanent magnet and gyro wheel are an assembly, have two assemblies on every fixed bolster at least, they are evenly arranged around the central line of silt remover organism. It is not fragile, and long service life passes through both pipelines of adaptable different diameters of a telescopic link and a permanent magnet and the 2nd permanent magnet combined action in the use, can dredge the pipeline of reducing again, and the range of application is wide.

Description

A kind of novel guide

Technical field

The utility model relates to pipeline cleaning mechanical field, especially a kind of novel guide.

Background technology

The guide of existing blow-off line dredger (namely supports the mechanism of the fuselage of dredger, this mechanism's object is the center making dredger be in the pipeline that will dredge all the time) though the pipeline adapting to different size can be regulated, but be all regulate guide in advance according to the diameter of the pipeline that will dredge, guide after regulating is fixing immutable, the pipeline (namely the wide some places of pipeline some places are narrow) running into some reducings is just helpless, cannot dredge the pipeline of reducing.

Utility model content

The utility model is intended to solve the problem, provide a kind of novel guide, it is not fragile, long service life, the pipeline of different-diameter in use both can have been adapted to by expansion link and the first permanent magnet and the second permanent magnet acting in conjunction, can dredge the pipeline of reducing again, applied range, its technical scheme adopted is as follows:

A kind of novel guide, it is characterized in that, comprise: fixed support, first permanent magnet, expansion link, support member, second permanent magnet and roller, described fixed support detachable connection is on dredger body, described first permanent magnet is fixed on fixed support, described expansion link is made up of fixed bar and motion bar, the bottom of described fixed bar and fixed support Joint, described motion bar to be threaded onto in fixed bar and to be slidably connected with fixed bar, described motion bar top and support member Joint, described roller and support member are hinged, the center line of described expansion link and the center line of dredger body perpendicular, described support member is formed with the cell body for accommodating second permanent magnet, described second permanent magnet is with the first permanent magnet one_to_one corresponding and homopolarity is relative, with interconnective first permanent magnet, expansion link, support member, second permanent magnet and roller are an assembly, each fixed support have two assemblies at least, they are evenly arranged around the center line of dredger body.

On technique scheme basis, the assembly on each fixed support is two, and the center line of the expansion link on the center line of the expansion link on left fixed support and right fixed support is perpendicular.

On technique scheme basis, described first permanent magnet is annular, and the fixed bar of described expansion link passes toroidal cavity and the fixed support Joint of the first permanent magnet.

The utility model tool has the following advantages: not fragile, long service life, in use both can be adapted to the pipeline of different-diameter by expansion link and the first permanent magnet and the second permanent magnet acting in conjunction, can dredge the pipeline of reducing again, applied range.

Detailed description of the invention

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

As depicted in figs. 1 and 2, the novel guide of one of the present utility model, it is characterized in that, comprise: fixed support 2-1, 2-2, first permanent magnet 3, expansion link 4, support member 6, second permanent magnet 5 and roller 7, described fixed support 2-1, 2-2 detachable connection is on dredger body 1, described first permanent magnet 3 is fixed in fixed support 2-1, on 2-2, described expansion link 4 is made up of fixed bar and motion bar, the bottom of described fixed bar and fixed support 2-1, 2-2 Joint, described motion bar to be threaded onto in fixed bar and to be slidably connected with fixed bar, described motion bar top and support member 6 Joint, described roller 7 is hinged with support member 6, the center line of described expansion link 4 and the center line of dredger body 1 perpendicular, described support member 6 is formed with the cell body 8 for accommodating second permanent magnet 5, described second permanent magnet 5 is with the first permanent magnet 3 one_to_one corresponding and homopolarity relative (namely the first permanent magnet and the second permanent magnet are the state of repelling each other), with interconnective first permanent magnet 3, expansion link 4, support member 6, second permanent magnet 5 and roller 7 are an assembly, each fixed support 2-1, 2-2 have two assemblies at least, they are evenly arranged around the center line of dredger body 1.This design is without the need to spring, find through experiment: one, spring in use easily lost efficacy owing to will repeatedly stretch, if spring is arranged in expansion link by two, because the working environment blow-off line of blow-off line dredger is very severe, some foreign material easily enter in expansion link to be stuck on spring and cause spring failure, three, because working environment is very severe, usually comparatively moist, spring easy-to-rust.Therefore the application adopts the mode that two pieces of magnet homopolarities are relative, structure is simple, not fragile, long service life, can not corrosion, is not afraid of dirt, foreign material.

Preferably, each fixed support 2-1, the assembly on 2-2 is two, and the center line of the expansion link 4 on the center line of the expansion link 4 on left fixed support 2-1 and right fixed support 2-2 is perpendicular.

As shown in Figure 3, preferably, described first permanent magnet 3 is annular, and the fixed bar of described expansion link 4 passes toroidal cavity and fixed support 2-1, the 2-2 Joint of the first permanent magnet 3.

Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
