The invention discloses a combined electric suspension crane, the lower part of the wall plate is connected with the end beam by a pin shaft, the middle part of the end beam is welded with a flange and the hanging plate on the main beam is connected by a high-strength bolt, and the lower side of the main beam is hung with a hanging beam electric sports car. The hanging beam sports car comprises a hanging walking beam, an electric sports car and a hanging beam walking beam. Horizontal wheels are installed on the outer side of each suspended walking beam electric sports car, rear roller groups are installed on the inner side of the paired suspended beam sports car, and fixed on the upper cover plate of the suspended beam through flanges and bolts, and the low clearance electric hoist is installed at the lower part of the suspended walking beam and the upper end beam. A safety card is installed in the part, and the safety card is connected with the end beam by a bolt group. The combined electric suspension crane of the technical scheme can be transported from the gate to the factory building, which is impossible for the ordinary suspension crane at present. Moreover, the structure saves material and labor costs, saves space, and the structure is more compact.

一种组合式电动悬挂起重机
本专利技术涉及一种组合式电动悬挂起重机。
技术介绍
目前的电动悬挂起重机,是由电动跑车、墙板、三角吊板、端梁、主梁吊板和主梁组成,电动跑车的墙板与三角吊板用两个穿钉连接,三角吊板与端梁用销轴连接,端梁中间再用销轴与主梁的吊板连接,这样做由于板和轴都比较多,做工也复杂,还浪费很大的空间。最重要的,这种悬挂起重机无法从大门外取物运到大门内,作业范围小,在很多场合不能使用。专利号:CN107673229A公开一种悬挂起重机,该方法只能适合小吨位的起重机,如果起重机的吨位大,吊物很重,旋转部位和旋转梁是承受不住的。再者该结构需为双梁结构,就需要更多的原材料制作,不利于节能减排。
