The invention belongs to the technical field of hoisting equipment, and particularly relates to a trackless walking device of a portal crane, which comprises an external mounting bracket and a walking wheel mechanism, an externally-attached cross beam of the externally-attached mounting bracket is fixed between the lower parts of the two bearing supporting legs; an extension mounting pedestal is arranged on the side surface of the externally attached cross beam; a horizontal rotating arm of the walking wheel mechanism is rotationally connected with the extension mounting pedestal and a vertical swinging arm, and the vertical swinging arm is connected with a walking wheel; the telescopic electric cylinder can control the included angle between the two; and a first horizontal fluted disc at the inclined upper end of the horizontal rotating arm is in transmission connection with a steering motor. The trackless walking device in the scheme can be mounted and fixed on the tracked portal crane, so that the crane can be put into use before a track is built, and other cranes do not need to be rented for temporary use, so that the cost is reduced; due to the vertical height structure of the traveling wheels, the requirements of different scenes on the height of the portal crane are met.

    本发明属于起重设备技术领域,具体涉及一种门式起重机的无轨式行走装置,包括外附安装支架和行走轮机构;外附安装支架的外附式横梁固定于两条承重支腿的下部之间;在外附式横梁的侧面设置有外延安装台座;行走轮机构的水平转动臂与外延安装台座和竖向摆动臂转动连接,竖向摆动臂与行走轮相连;伸缩电缸能够控制两者之间的夹角;水平转动臂的斜上端的第一水平齿盘与转向电机传动连接。本方案中的无轨式行走装置能够安装固定到有轨式门式起重机上,使得起重机能够在轨道搭建完成前投入使用,无需再租借其他起重器进行临时使用,从而降低成本;行走轮竖向高度的结构,从而满足不同场景对门式起重机高度的要求。
