Abstract
The invention discloses an internal spraying device for a steel pipe, and relates to an assistant device for steel pipe processing. The internal spraying device comprises a self-positioning rotation walking trolley mechanism, a two-way walking trolley mechanism and a high-pressure air sweeping mechanism. The internal spraying device can achieve wide caliber processing range of the steel pipe, and can process a drinking water steel pipe, wherein, the diameter of the drinking water steel pipe ranges from 400 to 2200 mm, and the maximum length of the drinking water steel pipe can reach 15 m; the labor intensity and the occupational hazard of operating staff can be reduced; in addition, the cost is low, the efficiency is high, and the service life of the steel pipe is prolonged.
Description
Technical field
The present invention relates to a kind of steel pipe processing auxiliary equipment.
Background technology
In the steel pipe processing industry, the spraying of drinking water pipe diameter all is manually-operated, does not have special spraying equipment at present, and the small-caliber artificial spraying technology is very ripe, but the heavy caliber spraying effect is poor, and labour intensity is big.
Summary of the invention
The purpose of this invention is to provide a kind of steel pipe inner spray coating device; To solve the spraying of prior art drinking water using pipe diameter all is manually-operated, does not have special spraying equipment, and the small-caliber artificial spraying technology is very ripe; But problems such as the heavy caliber spraying effect is poor, and labour intensity is big.
The present invention solves the technical scheme that its problem adopts:
Before motor and swiveling wheel are set on the walking carriage, swiveling wheel and driver are set on the back walking carriage, driver adopts the reducing motor chain drive, forward and backward walking carriage is through the torque arm connection, constitutes self-align rotation walking carriage mechanism.
On the bidirectional walking chassis material storing box is set, its front side is provided with the coating syringe, and rear side is provided with driver; Material storing box one side is provided with the spraying arm, and spraying arm front side is provided with spray gun, establishes spraying arm support wheel in spraying arm front bottom end position; Spraying arm below is provided with spraying arm automatic regulator; The lower end of this spraying arm automatic regulator is a lifting unit, and the upper end is provided with sheave, and the spraying arm moves along sheave; Spraying pipeline one end connects the coating syringe, and the other end connects spray gun; Constitute bidirectional walking chassis mechanism.
Tracheae is fixed along the spraying arm, and front end is the gas outlet, and the other end connects air pump; The front position of walking carriage before air-introduced machine is arranged on connects centrifugal deduster through the air-introduced machine suction pipe, constitutes the pressure-air cleaning agency.
Adopting good effect of the present invention is that machined steel mouth of pipe footpath scope is big, can process the drinking water steel pipe of maximum 15 meters of Φ 400-2200mm, length, reduces labor intensity of operating personnel, occupational hazards, and cost is low, and efficient is high, improves the service life of steel pipe.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is a structural representation of the present invention;
1 preceding walking carriage, 2 motors, 3 swiveling wheels, 4 torque arm, 5 back walking carriages, 6 drivers, 7 spray guns, 8 spraying arm support wheels, 9 spraying arms, 10 spraying arm automatic regulators, 11 tracheaes, 12 spray pipelines, 13 coating syringes, 14 bidirectional walking chassis, 15 material storing box, 16 air pumps, 17 air-introduced machines, 18 air-introduced machine suction pipes, 19 centrifugal dedusters, 20 sheaves, 21 lifting units among the figure.
The specific embodiment
As shown in the figure: motor 2 and swiveling wheel 3 are installed on the preceding walking carriage 1, swiveling wheel 3 and driver 6 are installed on the back walking carriage 5, adopt the reducing motor chain drive, forward and backward walking carriage 1,5 is through torque arm 4 connections, constitutes self-align rotation walking carriage mechanism.
Tracheae 11 is fixing along spraying arm 9, and front end is the gas outlet, and the other end connects air pump 16; The front position of walking carriage 1 before air-introduced machine 17 is arranged on connects centrifugal deduster 19 through air-introduced machine suction pipe 18, constitutes the pressure-air cleaning agency.
During work, self-align rotation chassis is connected, the steel pipe rotation, and the bidirectional walking chassis advances; The spraying arm advances simultaneously, and the pressure-air cleaning agency is connected, and advances with the spraying arm, and the steel tube surface floating dust is blown afloat; Mechanism takes away floating dust by air inducing, and when arriving the steel pipe end points, the pressure-air cleaning agency stops, and the bidirectional walking chassis stops; And begin to retreat, spray gun is opened, and coating is by the pressurization of coating syringe, through taking advantage of the vaporific steel pipe inwall that is sprayed on along the pipeline of spraying arm setting through spray gun; When spraying, will spray arm by the spraying automatic regulating apparatus and lift, break away from the steel pipe that rotates, up to the spraying end near termination.
