Description

The lock of cleaning channels equipment draws propeller

The utility model relates to the duct cleaning device, specifically is that a kind of lock of cleaning channels equipment draws propeller.

In the pipeline of various uses and type, because pipeline is by behind all kinds of liquids, can produce attachment and sediment at inner-walls of duct, meeting generator tube pipeline equipment foreign matter stops up and causes not smooth, these equipment than complicated pipelines of cleaning often use helical spring and cleaning head to clean at pipe interior at present, and helical spring and cleaning head will lean on manual the propelling to carry, promptly time-consuming effort again, inefficiency.

The purpose of this utility model is to provide the helical spring that makes cleaning channels equipment to produce radially rotation and the axial lock of a kind of cleaning channels equipment of walking automatically draws propeller.

The utility model is achieved in that the lock of cleaning channels equipment draws propeller and is made up of directive wheel support 1, guide wheel shaft 2, pressing plate 3, alignment pin 4, directive wheel 5, spring 6, pin 7, groove 8, jackscrew 9, anti-slip tank 10, screw 11, spring cylinder 12, and three directive wheels 5 are distributed on that its center accompanies driven helical spring cylinder (12) on the plane of directive wheel support 1 axis normal; In directive wheel support 1 groove 8 fixing directive wheel 5 is arranged, and locate with screw 11; Pressing plate 3 is housed on the guide wheel shaft 2, and by pressing plate 3 and pin 7 location, directive wheel 5 is housed on the guide wheel shaft 2, guide wheel shaft 2 is contained on the directive wheel support 1 and can moves radially.

The directive wheel support is equipped with anti-slip tank 10 on 1 surface, and anti-slip tank 10 can protrude, also can be recessed, and there is spring 6 pressing plate 3 belows, and jackscrew 9 is arranged on the support 1.

Directive wheel 5 is between 20 °～25 ° along the angle of the plane formation of axis and directive wheel support 1 axis normal.

Directive wheel 5 adopts hermetically sealed lubricating bearings, bearing centre dress axle sleeve.

Advantage of the present utility model is: when center spring cylinder rotates, thereby three directive wheels can produce axial force and promote the spring cylinder and move axially to reach and advance walking automatically, need not manual promotion, directive wheel is hermetically sealed lubricating bearings, do not produce corrosion, can avoid the erosion of dirt, foreign matter, maintenance and easy maintenance.

Fig. 2 is a structure side view of the present utility model;

Fig. 3 is an external structure schematic diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is further described:

This use is novel to be made up of directive wheel support 1, guide wheel shaft 2, pressing plate 3, alignment pin 4, directive wheel 5, spring 6, pin 7, groove 8, jackscrew 9, anti-slip tank 10, screw 11, spring cylinder 12, three directive wheels 5 are distributed on the plane of directive wheel support 1 axis normal, its center accompanies driven helical spring cylinder 12, and directive wheel 5 is between 20 °～25 ° along the angle of the plane formation of axis and directive wheel support 1 axis normal.In directive wheel support 1 groove 8 fixing directive wheel 5 is arranged, and locate with screw 11; Pressing plate 3 is housed on the guide wheel shaft 2, and by pressing plate 3 and pin 7 location, there is spring 6 pressing plate 3 belows, the fulcrum of pressing plate 3 relative front ends resets after depressing or lifting.Directive wheel 5 is housed on the guide wheel shaft 2, and guide wheel shaft 2 is contained on the directive wheel support 1 and can moves radially.Three directive wheels 5 have two to fix, and one is movably.The directive wheel support is equipped with anti-slip tank 10 on 1 surface, and anti-slip tank 10 can protrude, also can be recessed, jackscrew 9 is arranged on the support 1.Directive wheel 5 adopts hermetically sealed lubricating bearings, and bearing centre is equipped with axle sleeve.

Three directive wheels 5 are distributed on the plane of directive wheel support 1 axis normal with trisection, wherein two is stator wheel, be fixed in the groove 8 that forms angle, and it is fixing by standard component screw 11, another is removable directive wheel, be installed on the guide wheel shaft 4, these directive wheel 5 formed angles are by pressing plate 3 and guide wheel shaft connecting pin control positioning form, angle between the plane of three directive wheels 5 and directive wheel support 1 axis normal forms one 20～25 °, the size of this angle form the axially-movable speed of decision spring cylinder 12.

Pressing plate 3 presses down, promoting directive wheel 5 moves downward, three directive wheels, 5 middle spring cylinders 12 are tightly clamped, when spring cylinder 12 being rotated with various driving power hand-held, that guide and support, the formed lead angle of the angle of three directive wheels 5 promotes that spring cylinder 12 is rotation and along axial-movement, and the direction of rotation difference can realize advancing or retreating.

Three directive wheels 5 are fixed by standard component, all adopt hermetically sealed lubricating bearings, and bearing centre dress axle sleeve is when directive wheel 5 is fixed, still freely rotatable.

Alignment pin 4 is installed on the directive wheel support 1, thereby has guaranteed to be driven spring cylinder 12 whirligigs and to be damaged because of maloperation damages.

Adopted the principle of intersection wheel mechanism, when promoting guide wheel shaft when the center moves axially, but holddown spring cylinder, three directive wheels and spring cylinder are rotated simultaneously, at this moment, the angle of three directive wheels becomes lead angle, thereby can produce axial force promotes the rotation of spring cylinder and moves axially the purpose that reaches automatic walking, can be according to the direction difference of spring cylinder rotation, realizing advances or retreat mobile, used directive wheel has adopted standardized designs, three directive wheels are hermetically sealed lubricating bearings, permanent lubricating condition be can keep, internal corrosion, the loss of reducing friction are difficult for producing, also can avoid dirt, the erosion of foreign matter, this device guiding wheel support 1 adopts with being connected of driving spring cylinder 12 whirligigs and is threaded, and dismounting is very convenient and reliable, and its overall structure can make maintenance and easy maintenance.
