Embodiment Construction
[0037] Embodiment. The specific embodiment of the present invention is described with this example and the present invention is described further. This example is an experimental prototype for anti-corrosion layer spraying during the overhaul of Φ720mm crude oil pipeline anti-corrosion layer, and its composition is as follows figure 1 , figure 2 , image 3 shown. Axial travel motor 13 chooses German sew geared motor model KA47DT90S4-BG; reducer 10 German sew geared motor model KA47DT90S4-BG; circumferential swing motor 8 chooses German sew geared motor model KA37DR63M4; frequency regulator chooses Emerson EV1000-2S0015G; tilt sensor 9 choose Beijing Tianhaike product model: QXJ-BZ-V; 25 choose JHPK-ZD spray gun.
[0038]The axial traveling mechanism is decelerated by a variable frequency motor 13 through a reducer 10, and driven by a sprocket 11, a chain 12, a sprocket 16, and a chain 18 to drive four conical wheels 15 on the walking trolley 14, so that the walking trolley...

The invention provides a conduit on-site heavy maintenance automatic spraying machine for spraying an anticorrosive coating layer after the conduit is excavated. An axial traveling electric motor (13) is disposed on the fame surrounding the conduit at the upper surface of the conduit (22), the output shaft (10) thereof is connected to a rear connection chain wheel of a speed reducer (10), and is driven by a chain (12) to drive four conical wheels (15) of a driven moving cart (14). The central axle of the four conical wheels (15) and two set of clamping wheels (23) on the conduit surrounding the conduit subdivision frame (19) are disposed evenly at the circumference of the conduit (22), and the subdivision frame (19) closures up with a movable connection at the conduit bottom. The circumferential swing mechanism is an inside and outside circular frames configuration capable of rotating relatively, the outside frame (3) is connected to the tail of the moving cart (14) by a connection block (7), and the inside frame is mounted on a rail of the outside frame (3) by a rolling wheel (2). A spray gun is disposed on a spray gun holder (26) on the inside frame (1). The circumferential swing mechanism is connected to the driving sprocket (6) by a speed reducer, driven by a chain (4), a switch sprocket (27), and a guide sprocket (28), to drive an inside frame rotating arm, so as to drive the inside frame to swing reciprocally.
Description
technical field [0001] The invention is an automatic spraying machine tool for on-site overhaul of pipelines, which is suitable for spraying anticorrosion layers after excavation of pipelines, especially large-diameter pipelines. It relates to the technical field of piping systems. Background technique [0002] Industrial pipelines are commonly used transportation tools in the energy and chemical industries. Due to the influence of the surrounding working conditions, they are susceptible to corrosion, especially for old pipelines that have been in operation for a long time. It will affect the safe operation of the pipeline. Therefore, automatic spraying machines suitable for pipeline anti-corrosion layer repair are widely valued. [0003] At present, foreign mechanical repair equipment has been able to realize the in-ditch and out-of-ditch repair of pipelines under the condition of stoppage or non-stop delivery, and has matching above-ditch and under-ditch repair equipment...
