WDJ碗扣型多功能脚手架,是由铁道部专业设计院研制成功的一种最新型的多功能脚手架。1986年10月在“全国第二届发明展览会”上,获得铜牌奖。并被国家科委和全国发明协会推荐参加1987年4月在日内瓦召开的“第十五届日内瓦国际发明和新技术展览会”展出。这种多功能脚手架的立杆或横杆上每隔60厘米按装一付带齿碗扣接头,其中下碗扣直接焊在立杆上,上碗扣顶部带有螺旋面,用限位销限位,当上碗扣的缺口对准限位销时,上碗扣即能沿立杆上下滑动。连接时,先将横杆接头插入下碗扣的周边带齿的圆槽内,将上碗扣沿限位销扣下,并顺时针旋转扣紧,用铁锤敲击几下即可牢固扣紧。WDJ碗扣型多功脚手架与目前常用的扣件式脚手架相比,有以下一些优点:
WDJ bowl buckle type multifunctional scaffold is a new type of multi-functional scaffold developed by the professional design institute of the Ministry of Railways. In October 1986, he won the bronze medal at the Second National Invention Exhibition. It was recommended by the State Science and Technology Commission and the National Association of Inventions to participate in the “15th Geneva International Invention and New Technology Exhibition” held in Geneva in April 1987. This multi-functional scaffolding pole or crossbar is equipped with a toothed bowl buckle joint every 60 centimeters, wherein the lower bowl buckle is directly welded on the pole, the upper bowl buckle has a spiral surface at the top, and the limit pin is used. Limit, when the gap in the upper bowl buckle is aligned with the limit pin, the upper bowl buckle can slide up and down along the pole. When connecting, first insert the crossbar joint into the round groove with the teeth around the bottom of the bowl buckle, buckle the upper bowl buckle along the limit pin, and rotate it clockwise to fasten it. Use the hammer to strike a few times to firmly buckle. tight. Compared with the currently used fastener-type scaffolds, the WDJ bowl buckle multi-function scaffold has the following advantages:
