The foldable hoisting equipment for municipal construction comprises a cross beam, supporting seats are installed at the two ends of the cross beam respectively, rotating seats are installed on the portions, located above the two sides of the cross beam, of the supporting seats respectively, and supporting columns are hinged to the rotating seats respectively; longitudinal containing grooves are formed in the positions, located on the two sides of the cross beam, of the supporting base correspondingly, and the distance between the containing grooves in the two sides is wide in the lower portion and narrow in the upper portion. In the working state, the supporting columns rotate through the rotating seats and extend to the ground, the supporting columns are located on the lower sides of the rotating seats and clamped into the containing grooves to be fixed, the two supporting columns on the supporting seats on each side extend to the ground in a splayed shape, and in the folding state, the four supporting columns are transversely folded inwards and are close to one side of the cross beam. The cross beam is used for installing electric hoists. According to the equipment, the height of the whole hoisting equipment is reduced through the folded supporting columns, transportation is convenient, the supporting columns are in matched positioning connection with the containing grooves of the rotating base and the supporting base, the supporting columns are very convenient to unfold, install and disassemble, the structural strength is high, and stability is good.
市政施工的可折叠式起重设备及使用方法,包括横梁,横梁的两端分别安装有支撑座,支撑座在位于横梁两侧的上方分别安装有转动座,各转动座上分别铰接有支柱;支撑座位于横梁的两侧分别设有纵向的放置槽,且两侧所述放置槽之间的距离下宽上窄;工作状态下,支柱通过转动座转动并伸向地面,支柱位于转动座的下侧卡入放置槽中固定,每侧支撑座上的两个支柱呈八字形伸向地面,折叠状态下,四个支柱向内横向折叠,并靠近横梁一侧;横梁用于安装电动葫芦。设备通过折叠的支柱,降低了整个起重设备的高度,运输方便,支柱通过与转动座和支撑座的放置槽配合定位连接,支柱展开、安装、拆卸均非常方便,且结构强度高、稳定性好。
