(3), support and the crane of pitch round brush mechanism with a pair of identical round brush, round brush join, reductor is by driving chain and be fixed in two round brush backward rotation of gear drive of roller brush shaft one end, the nozzle of Asphalt-distributing spray head is located between two round brush.
With above-mentioned any scheme implementation the utility model the time, horizontally moving device and vertical conveyor structure can realize like this: lift is by crane, the vertical drive screw of lower end and crane Joint, the transmission nut that is connected as a single entity with assembly pulley, the driving wheel that is connected on the motor output shaft is formed with the driving gear set that the driven pulley that is socketed on the transmission nut constitutes, as the assembly pulley of horizontally moving device with the horizontal gird channel-section steel of frame as pulley track, the two ends of the driving chain that the same respectively gear that drives with inorganic buncher in the both sides of assembly pulley is meshed are connected.
For also being realized like this by the rotary support mechanism of spraying cast iron pipe:
Pipe socket end, female end bracing frame contain a vertical support cylinder 2,4 respectively, and their pole is joined to two carrying roller inner faces of 1,5 with corresponding carrying roller respectively.
The carrying roller 1 of socket end bracing frame is a circular cone shape, and the carrying roller 5 of female end bracing frame is cylindric.
Carrying roller in socket end, the female end bracing frame is furnished with a pair of auxiliary carrying roller respectively to 1,5 separately both sides.
The utility model advantage is:
1, the applicable length of the utility model is 5~9m or various surface of cast iron spraying pitches longer, DN100~2600mm; Compared with prior art, can save 2/3 pitch during spraying; Because machinery has substituted manually, has freed the workman and has suffered the harm of pitch aerosol.
2, improved production efficiency greatly, for DN100~1000 outer tube surfaces spraying (brushing) pitch, if adopt single station machine, be 60~150 seconds/one pipe man-hour; If adopt the double machine, its production efficiency doubles, and be 60~150 seconds/two pipes man-hour.
3, the product quality ISO8179 specification requirement that meets international standards fully, promptly surperficial sprayed coating thickness is even, and average thickness is not less than 70 μ m, minimal thickness is not less than 50 μ m, and sprayed coating has excellent adhesion, shortcomings such as no spot or drip shape.
Fig. 1 is the utility model general structure schematic diagram.
Fig. 2 is that the spray body B-B of first kind of scheme of the utility model is to structural representation.
Fig. 3 is that the spray body B-B of second kind of scheme of the utility model is to structural representation.
Below in conjunction with drawings and Examples the utility model is done further narration:
As shown in Figure 1, in an embodiment the utility model by column 6, stepless speed-change motor 7, driving chain 8, crane 9, the lifting axis of guide 10, lifting drive motors 11, drive screw 12, move horizontally assembly pulley 13, crossbeam channel-section steel 14, spraying (brushings) device 18, board-like cable 15, sprocket wheel 16, pipe socket end carrying roller to 1, supporting cylinder 2, travelling car 3, trolley track 17, bell of pipe end carrying roller to 5, support cylinder 4 and form.
Crossbeam channel-section steel 14 has constituted frame with column 6, and channel-section steel 14 is again the guide rail that moves horizontally of assembly pulley 13 simultaneously; Spraying (brushing) mechanism 13 is contained on the crane 9; Motor 11 can make drive screw 12 be with crane 9 oscilaltions by gear train; A whole set of elevating mechanism and assembly pulley 13 are connected as a single entity, but motor 7 by chain 8 drive pulley groups 13, with crane 9 and on spraying (brushing) mechanism 18 moved back and forth along level; Processed cast iron pipe can be delivered to carrying roller between 1 and 5 by the stepping conveying mechanism, socket end (pipe head) place carrying roller on 1, female end (pipe major part) places carrying roller on 5, the rotation in the same way under reductor drives respectively of the two pairs of carrying rollers, drive the metal tube that props up on them also rotate, make the whole cylindrical outer surface of pipe can both by from above pitch spray (brush) be coated onto; The pole of supporting cylinder 2,4 is all joined to 1,5 inner face with carrying roller respectively, cylinder just can be controlled carrying roller and departs from level and slope inwardly like this, just can guarantee between carrying roller and the metal tube that in rotation process just line contact rather than the face contact, so just can prevent that carrying roller from destroying the bitumen layer that the pipe end has coated when transmission; As we know from the figure, carrying roller 1 be shaped as the frustum of a cone, and carrying roller 5 is shaped as cylinder, this is because pipe socket, female end circumferential length difference, and will keep whole pipe smooth rotation and be in level all the time, the rotational line speed of its two ends just can not be identical.Identical for guaranteeing pipe two ends rotating speed, must be along determining suitable carrying roller shape, diameter and rotating speed.
Explained the operation principle of spraying pitch below again by Fig. 2: transmission nut 20 is connected as a single entity with horizontal trolley group 13, the gear 19 of socket on the nut 20 is meshed with the output gear of motor 11, when motor 11 rotates, can make nut 20 drive screws 12 that axial displacement takes place, thereby drive spray gun 21 oscilaltions that are contained on the crane 9, according to the different height of adjusting lifting of the diameter of processed pipe.Spray gun 21 adopts be high pressure airless spray equipment be equipped with porous (0.13~1.55mm) nozzle, its pitch that will atomize above pipe sprays to the outer surface of pipe, one time coating thickness can reach 300 μ m.Along with rotation and the assembly pulley 13 of pipe under carrying roller drives drives spray gun 21 and axially move back and forth along pipe, the outer surface of whole pipe can be sprayed fully.
What Fig. 3 showed is to brush pitch mechanism, and it moves horizontally, the structure of oscilaltion and operation principle are identical with what show among Fig. 2, no longer repeats herein.Its round brush is made up of two identical round brush of structure 22, and Asphalt-distributing spray head 21 is connected between two brushes, and motor 25 can drive two round brush and relatively rotates by chain 24 and the gear that is contained in the brush axle head.During work, round brush 22 need reduce to can be tangent with pipe height, then by shower nozzle 21 for pitches to pipe, round brush rotates brushing.The rotation of pipe, assembly pulley 13 drive roller brushes structure and axially move back and forth along pipe, can guarantee that the outer surface of whole pipe is brushed to pitch.
