Abstract
The utility model discloses a device which clamps a flexible shaft to rotate, and the device is provided for a pipeline cleaning machine which conveys flexible shafts automatically. The utility model comprises a driven wheel and a flexible shaft clamping mechanism which is driven by the driven wheel and evenly distributed on the outer diameter of the flexible shaft. The device only applies torque on the flexible shaft via an idler wheel type clamping jaw to enable the flexible shaft not to be restricted by the device when the flexible shaft dose axial movement under the action of other conveying mechanisms.
Description
The present invention relates to clear up a kind of device of drainage pipeline special-purpose machinery, specifically, is the device of a kind of clamping flexible axle rotation of providing of the tube cleaning for the automatic transport flexible axle.
At present, cleaning dredging drainpipe road has been extensive use of the flexible axle that a kind of garden shape spring that equivalent length arranged is made, flexible axle is rotated in pipeline and carries with manual or motor-driven method, thereby reach the purpose of clearing up pipeline.
In the prior art, the tube cleaning of automatic transport flexible axle, for to the rotating speed of flexible axle, turn to transfer rate and control respectively, generally be with flexible axle rotatablely move and axially-movable adopts two groups of mechanisms to drive respectively.
In the rotating driving device of flexible axle, a kind of mode is to be wiped the jaw clamping flexible axle external diameter of clutch by the two gardens of three lobe types taper thread grinding, is rotated under the driving force effect, as CN86209566; Disclosed device in 91225379 patent documentations such as grade.Because the jaw of these devices is friction watt formula jaws made from high-abrasive material, when clamping flexible axle external diameter was rotated, the axial freedom of flexible axle was retrained by jaw.When therefore by the another set of flexible axle conveying mechanism in the same machinery flexible axle of rotation axially being carried, the mutual interference with causing between axial driving force and the rotation clamping friction makes efficient low, serious wear.
Another kind of rotation type of drive is that whole flexible axles are wound in the cylinder type container, when cylinder rotates, drives the flexible axle rotation.As US4364139; Disclosed device in 4395791 patent documentations such as grade.Although these devices are better than other like product on the market significantly, their applicability still has deficiency; In order to satisfy the needs of mediation distance, to hold long as far as possible flexible axle in the cylinder, this makes cylinder have sizable radial dimension and weight, must be reduced to half of flexible axle optimum operating speed to drum rotation speed when following for this reason, just can make the operator accept the vibration that produces by the cylinder rotary centrifugal force.Moreover, because the force direction difference of cylinder when difference turns to, flexible axle is unrolled in cylinder and tangle.
The objective of the invention is to: provide a kind of simple, light tube cleaning to drive the clamping device of flexible axle rotation, this device is axially carried under the prerequisite of motion not limiting flexible axle, and the rotation torque that can effectively the tube cleaning dynamical system be provided is passed to flexible axle.
Solution of the present invention is: the friction type jaw in the common tube cleaning clamping flexible axle whirligig is changed into garden shape roller type jaw, by the clamping of several pair of rollers flexible axles, make original friction clamping mode change into the rolling method of clamping.
Be distributed in the clamping device on the flexible axle external diameter as the roller of jaw, the axis of roller time rotational is vertical mutually with the rotation of clamping device.When roller clamping flexible axle was rotated motion, the moment of torsion pair roller that acts on the flexible axle produced normal force; Simultaneously, flexible axle is under another conveying mechanism effect, when carrying out axially-movable, the rotation of the roller of clamping flexible axle with the axially-movable of flexible axle, the flexible axle pair roller produces tangential force, because the normal force that acts on the roller is vertical with the tangential force direction, can think to be independent of each other.So this device is opened the moved apart of flexible axle on both direction by roller, therefore can not cause of the interference of pipeline cleaning machinery clamping flexible axle whirligig to axial conveying active force.
When tube cleaning passes through the clamping device driving flexible axle rotation of roller type jaw, only flexible axle is applied moment of torsion, and do not limit the axially-movable of flexible axle.Make the flexible axle of this device clamping rotation, under other axial conveying mechanism effect, realize cleaning necessary rotation of pipeline and axially-movable expeditiously.
Because flexible axle is to be twined by steel wire to make, external diameter is the garden cylindricality in the shape of a spiral, and flexible axle is when axially-movable, and roller external diameter garden axis direction outside flexible axle rotates, and can enclose one to produce on the steel wire than macrorelief, forms vibration.For roller is steadily rolled on flexible axle, the outer radius of roller need be processed into the field of conjugate action that adapts with flexible axle.This engagement shape is equivalent to the engagement of worm and wheel.Flexible axle is equivalent to single head garden arc-contact worm, and roller is equivalent to indent garden curved tooth worm gear, and the design processing of roller gets final product by garden curved tooth worm gear calculating processing.
The present invention is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structure cutaway view of first embodiment of the invention.
Fig. 2 is the cutaway view that Fig. 1 prolongs the A-A line.
In structure illustrated in figures 1 and 2, be distributed on the tapered jaw 2 in three outer gardens on the flexible axle external diameter direction, formed the two gardens of cover taper thread grinding jointly with the interior garden tapered sleeve 1,4 at its two ends and wiped clutch, tube cleaning in the past clamps flexible axle by this device.Now, one group of " jaw " that can roll---roller 3 is housed in the every jaw 2, it also can be many forward arrangements that every group of roller can be one.Be designed to a roller among Fig. 1.Every roller is supported by a bearing pin 6 that bearing 5 is housed.The power of motor or internal combustion engine drives tapered sleeve 1 rotation by driven pulley after slowing down, other end tapered sleeve 4 can move axially, when mobile tapered sleeve 4 compresses jaw 2, jaw is by roller clamping flexible axle 8 external diameters, simultaneously, under the outer garden conical surface friction effect of the garden conical surface and jaw 2 within it of the tapered sleeve 1 of rotation, jaw 2 is driven to rotate, and the flexible axle of roller and clamping thereof is rotated jointly.
Owing to bearings is arranged in the roller, not and other part connection in the clamping device, so its rotation is not subjected to the constraint of clamping device.The flexible axle that is driven by this device and rotate can carry out axial push-and-pull campaign easily.Therefore, under the prerequisite that does not cause interference, can be the axial conveying mechanism of another set of flexible axle that is installed in same cleaning machinery inside provides single flexible axle to rotatablely move.
When mobile tapered sleeve 4 leaves jaw 2, make jaw separately by the tension force effect of spring 7, the roller in the jaw leaves the flexible axle external diameter simultaneously, and clamping device separates with flexible axle.
Certainly, by the jaw of roller as flexible axle, its structure is not limited to above-mentioned form, can also be other similar type.
