Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
In the spraying process of ductile iron pipe, driven by motor is located at the top rotation of ductile iron pipe two-port, top drive ductile iron pipe rotation, the spraying dolly that spray gun is housed is walked to the other end from pipe one end above cast iron pipe, to the tube outer wall spraying that is positioned at below, when spraying carriage walking is during to the female end of ductile iron pipe, if spray gun also sprays by original direction, coating has on most top and ground that sprays to push pipe, cause unnecessary spillage of material, and owing to spraying to top upper and ground coating simultaneously because the coating that top rotation makes to spray on top is thrown on ductile iron pipe again, not only need manually to clear up separately, cause unnecessary labour cost and waste of time, corresponding increase labour intensity and delay time at stop, also can have influence on the presentation quality of ductile iron pipe.
The utility model has been taked following technical scheme for above problem, adopt a bearing block 7 for supporting, laterally tooth bar 8 is horizontally through the centre of bearing block 7, laterally tooth bar 8 is provided with dovetail groove, can be along the slideway left and right slippage on bearing block 7, its middle gear 2 is positioned at the center of bearing block 7, the vertical center through gear 2 of power transmission shaft 1, the bearing 6 that is contained in bearing block two ends Shang Xia 7 that relies on up and down of power transmission shaft 1 supports, the end of bearing 6 is equipped with bearing cap 9, bearing cap 9 is below passed in the lower end of power transmission shaft 1, and spray gun is installed on the lower end of power transmission shaft 1; Laterally one end of tooth bar 8 is provided with back-moving spring 4, and described back-moving spring 4 is placed in in the vertical spring base being connected 3 of bearing block 7, and the upper end of bearing block 7 is provided with the connecting axle 5 for being connected with spraying dolly.Spring base 3 is fixedly connected with bearing block 7 by bolt, and the end of spring base 3 is end cap, and this end cap can be dismantled, and is convenient to change installation back-moving spring 4.
In the slideway that laterally tooth bar 8 can directly arrange on bearing block 7, horizontally slip, but such structure can cause the wearing and tearing of bearing block 7, relatively waste material and change bearing block 7, also waste time and energy, therefore, preferably at the interior slide rail 10 that is laterally provided with in addition of bearing block 7, laterally tooth bar 8 is slidably matched with described slide rail 10, this slide rail 10 can directly weld together with bearing block 7, also can clamping or bolt fix, after slide rail 10 wearing and tearing, can only change slide rail 10, relative reducing labor intensity and reducing production costs.
The utility model links together by connecting axle 5 and spraying dolly, spraying carriage walking, drive bearing block 7 entirety to move thereupon, in the time of the middle part of spray ductile iron pipe, because horizontal tooth bar 8 is not subject to external force, laterally tooth bar 8 remains static, spray gun normally sprays, in the time spraying carriage walking to spheroidal graphite cast-iron tube faucet position, laterally tooth bar 8 pushes up on the fore-set of being located at socket, spraying dolly continues walking forward, laterally tooth bar 8 is because the stressed slideway along bearing block 7 moves to right, compression reseting spring 4, now laterally tooth bar 8 driven gears 2 rotate, gear 2 rotates and drives power transmission shaft 1 to rotate, and then the spray gun that drive is connected with power transmission shaft 1 rotates, make spray gun just in time rotate the angle of 90 degree, now make the spout of rifle just in time aim at bellmouth, spray, after having sprayed, the reversion of spraying dolly, now laterally tooth bar 8 separates with fore-set, laterally tooth bar 8 is got back to original position under the effect of back-moving spring 4.
The utlity model has simple and practical, flexible and convenient to use, the easy advantage of making.The utility model is arranged on spraying dolly, spray gun is arranged on power transmission shaft 1, drive power transmission shaft 1 to rotate by horizontal tooth bar 8 gears 2, and then drive spray gun to rotate, make spout just in time aim at bellmouth position, avoid spray painting to arrive top and ground, cause unnecessary spillage of material, and the labour intensity increasing because of cleaning.
The power of the horizontal tooth bar 8 of the utility model carrys out the fore-set that comfortable female end arranges, and without electric power and source of the gas, laterally tooth bar 8 tops are to fore-set, obtain power, compression reseting spring 4, realizes the certain angle of spray gun automatic rotation, and set back under the effect of back-moving spring 4, easy to use.
The utility model effectively in production control process coating be sprayed onto the waste of material causing on top and ground, play energy-saving and cost-reducing, to reduce labour intensity effect, and avoid the labour cost that increases because of cleaning drippage expense coating and consuming time, be conducive to increase work efficiency.
The utility model has the advantages such as Meteorological is few, installation replacing is easy, has good value for applications.
