Specific embodiment
The present invention is further described below.
As shown in Figure 1 and Figure 2, automatically walk inner-walls of duct polishing and grinding apparatus disclosed by the invention, including support component, walking
Component, rubbing down component and runner assembly.The support component includes dolly 5 and supporting leg 9, and the supporting leg 9 is peripherally disposed
In 5 periphery of dolly.The walking component includes the first motor 12, driving wheel 16 and drive shaft 17, and the driving wheel 16 is arranged at
In drive shaft 17, first motor 12 is arranged on dolly 5 and is connected with drive shaft 17.The rubbing down component includes mill
1 and electrical grinding machine 2, the bistrique 1 is arranged on electrical grinding machine 2.The runner assembly includes the second motor 7, external gear 4 and has
The pivoting support 6 of internal gear, second motor 7 are arranged on dolly 5 and are connected with external gear 4, the pivoting support 6
Including the inner ring 61 and outer ring 62 that mutually can rotate, the external diameter of the outer ring 62 is adapted with the radial dimension of dolly 5 and edge
Circumferentially fixed on the inwall of dolly 5, the inner ring 61 is connected with external gear 4, and the electrical grinding machine 2 is solid by connector 3
On 61 side of inner ring of pivoting support 6.
When carrying out inner-walls of duct rubbing down using the automatically walk inner-walls of duct polishing and grinding apparatus, whole polishing and grinding apparatus are positioned over
In pipeline, supporting leg 9 is contacted with inner-walls of duct and support dolly 5, the driving wheel 16 of component of walking generally is needed also exist for and pipeline
The inwall effect of contacting, and drive driving wheel 16 to rotate by the first motor 12, dolly 5 is made along pipeline axially-movable.Rub to reduce
Wipe, roller can be generally set on supporting leg 9.6 points of pivoting support is 62 two parts of inner ring 61 and outer ring, between inner ring 61 and outer ring 62
Both are allow mutually to rotate with rolling element, outer ring 62 is fixed on dolly 5.With the rotation of the second motor 7, inner ring 61 exists
Rotate under the drive of external gear 4, electrical grinding machine 2 makes bistrique 1 do circumferential movement along inner-walls of duct surface with the rotation of inner ring 61,
Axially-movable with dolly 5 is engaged, so as to realize that the rubbing down to whole inner surface of pipeline is processed.Bistrique 1 may be selected various energy
The rubbing down part for meeting pipeline rubbing down processing request matched with electrical grinding machine, it is preferred that polishing sand cloth wire wheel is then adopted, and the throwing
Light Abrasive-cloth wire wheel can improve rubbing down radius with the raising of rotating speed, and device can be made to adapt to the rubbing down of oval internal diameter pipeline.
It is different from " adapting to the inner-walls of duct reconditioning operation remote control equipment of caliber on a large scale " in background technology, the present invention

9 angle of rear support leg is identical, it is ensured that 9 stressing conditions of supporting leg are identical, and is difficult that sliding occurs in pipeline circumference.
It is oval pipeline for different size, with certain bending radius or endoporus, it is ensured that supporting leg 9 can be very well
Ground plays its effect, as shown in figure 3, the supporting leg 9 includes screw rod 91, adjusting nut 92, holddown spring 94, split pin 95, fixed
Position steel pipe 96 and directional wheel 97, the adjusting nut 92 and positioning steel tube 96 are respectively arranged at 91 two ends of screw rod, the compression bullet
Spring 94 is set on screw rod 91 and is located between adjusting nut 92 and positioning steel tube 96, is to ensure that spring effect is stable, can be fixed
Position 96 top of steel pipe and 92 bottom of adjusting nut install pad 93 respectively additional, in 91 bottom of screw rod insertion positioning steel tube 96, institute
State that positioning steel tube 96 is corresponding with screw rod 91 to be offered long round tube hole and connected by split pin 95, the directional wheel 97 is arranged at fixed
Position 96 bottom of steel pipe, is provided with top board 10 at the top of the supporting leg 9,10 both sides of the top board are provided with side plate 11, the side plate 11
It is fixed on dolly 5.Thus by adjusting nut 92, the decrement of spring can be changed to adjust the height of supporting leg 9, so that little
5 axial line of car is overlapped with pipeline axial line, it is ensured that the uniformity in rubbing down circumference.In polishing and grinding apparatus during pipe walking,
With the change in pipeline aperture, directional wheel 97 can the automatic telescopic compensation under elastic force effect, it is ensured that dolly 5 is stablized.
Rubbing down can produce substantial amounts of dust, iron filings, be to reduce which for the impact of motor and gear pair, the rubbing down component
Positioned at the end of dolly 5 and extend dolly 5, between the dolly 5 and rubbing down component, be provided with dust-proof guard 19, it is described dust-proof
Baffle plate 19 is connected on the inner ring 61 of pivoting support 6, as inner ring 61 and electrical grinding machine 2 are rotated together, preferably makes dust-proof guard 19
Dolly 5 is completely covered and is blocked, to improve its dust-proof effect, be to simplify installation, dust-proof guard 19 can with central shaft 21
Frame 20 is fixed on inner ring 61 by stud 18 together.
Walking component can arbitrarily be arranged at the middle part in front and back of dolly 5, for convenience of arrangement, and which is separated with bistrique 1, described
, respectively positioned at the two ends of dolly 5, first motor 12 is fixed on dolly 5 by the first platform 13 for rubbing down component and walking component
It is interior, it is similar, the second platform 8 also can be set on dolly 5 to fix the second motor 7, first platform 13 is by solid
Fixed board 15 is connected with drive shaft 17, and first motor 12 is connected with drive shaft 17 by Timing Belt 14.Driving wheel 16 with
Need with enough frictional force to drive dolly 5 to move between inner-walls of duct, be that this can arrange the elasticity parts such as spring
Interaction force between raising driving wheel 16 and tube wall, and it is preferred that, the driving wheel 16 is located at below dolly 5,
Side in the fixed plate 15 near driving wheel 16 is provided with balancing weight, so can equally improve the frictional force of driving wheel 16,
And it is relatively more simple in structure.
