The utility model is related to a kind of nozzle guider, including nozzle and leading truck, the coaxially connected connecting tube in rear end of nozzle, the forward end seal of nozzle, the side wall of nozzle is circumferentially-spaced to be equipped with multiple apopores towards connecting tube；Leading truck includes more guiding trestles, every guiding trestle includes in conplane base portion, shoulder and neck, the base portions of more guiding trestles is circumferentially-spaced, is vertically set on the outer wall of connecting tube, the each one end of base portion far from connecting tube is bent to nozzle direction and extends to form shoulder along the axis direction of connecting tube, the either end facet of shoulder is equipped with pulley, the neck of every guiding trestle is connected to same point, the axis coaxle of the point and connecting tube.The utility model can make nozzle remain at pipeline center, nozzle is set not contacted with tube wall, the walking in the duct for keeping nozzle very gentle simultaneously, for dredged using high-pressure waterjet systems, washing and cleaning operation during do not damage pipeline or nozzle and pipeline avoided to collide generation spark.
Description
Technical field
The utility model is related to a kind of pipeline dredger more particularly to a kind of nozzle guiders.
Background technology
Used nozzle is using process during being dredged to municipal sewer using high pressure water backsurging principle
In due to dirt inhibition in sewer so that nozzle and sewer inner wall generate friction, and nozzle is worn in collision, generates fire
Flower so that nozzle walk in operation process it is random, if it is plastic conduit, it is also possible to pipeline can be damaged, if
When having fuel gas in sewer, the possibility of burning, explosion may be will produce.
Utility model content
The purpose of this utility model is to be directed to above-mentioned present situation, and providing one kind can keep nozzle to be always positioned at pipeline center,
Ensure nozzle and a kind of forever discontiguous device of tube wall, while can ensure the very gentle walking in the duct of nozzle, is used for
It is dredged, pipeline is not damaged during washing and cleaning operation or is avoided nozzle and pipeline to collide using high-pressure waterjet systems and generate spark
Nozzle guider.
The technical solution adopted in the utility model：A kind of nozzle guider, including nozzle and leading truck：The nozzle
The coaxially connected connecting tube in rear end, the forward end seal of the nozzle, the side wall of the nozzle is circumferentially-spaced to be equipped with multiple directions
The apopore of the connecting tube；The leading truck includes more guiding trestles, and the every guiding trestle includes same flat
Base portion, shoulder and the neck in face, the base portions of the more guiding trestles is circumferentially-spaced, decile is arranged in the outer of the connecting tube
Wall, each one end of the base portion far from the connecting tube are bent to the nozzle direction and along the axis sides of the connecting tube
To the shoulder is extended to form, the either end facet of the shoulder is equipped with pulley, and the neck of the every guiding trestle connects
It is connected to same point, the axis coaxle of the point and the connecting tube.
The effect of the utility model is：Nozzle can be made to remain at pipeline center, nozzle is made never to be contacted with tube wall,
Simultaneously keep nozzle very gentle walking in the duct, for dredged using high-pressure waterjet systems, washing and cleaning operation during
Pipeline is not damaged or nozzle is avoided to be collided with pipeline generates spark.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of nozzle guider provided by the utility model.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of nozzle guider provided by the utility model, including nozzle 1 and leading truck 2.Nozzle 1
The coaxially connected connecting tube 10 in rear end, the forward end seal of nozzle 1, and it is circumferentially-spaced equipped with multiple directions in the side wall of nozzle 1
The apopore 11 of connecting tube 10 makes the water (flow) direction of nozzle 1 for outflow of turning back along the entrance of connecting tube 10 and from apopore 11, makes spray
Head guider receives forward thrust.
Leading truck 2 includes more guiding trestles 21, and every guiding trestle 21 includes in conplane base portion 210, shoulder
Portion 211 and neck 212.
Preferably, four guiding trestles 21 are equipped with.
The base portion 210 of more guiding trestles 21 is provided at circumferentially spaced the outer wall in connecting tube 10, and each base portion 210 with
The axis of connecting tube 10 is vertical.
The each one end of base portion 210 far from connecting tube 10 is bent to 1 direction of nozzle and along the axis direction of connecting tube 10
Shoulder 211 is extended to form, the both ends of the either end facet of shoulder 211 are respectively provided with a pulley 22, and pulley 22 passes through bolts and nuts
It is fixed on the end face of shoulder 211, the diameter of pulley 22 is more than the width of the end face of shoulder 211, makes pulley 22 can be along pipe slides.
The one end of shoulder 211 far from base portion 210 extends to form neck 212 to the axis direction of connecting tube 10, and every is led
It is connected to same top 213 to the neck 212 of holder 21, the central axis at top 213 is conllinear with the central axis of connecting tube 10.
The utility model can make nozzle remain at pipeline center, so that nozzle is never contacted with tube wall, while making spray
The very gentle walking in the duct of head, for dredged using high-pressure waterjet systems, washing and cleaning operation during do not damage pipe
Road avoids nozzle from colliding generation spark with pipeline.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
