The invention relates to the technical field of hoisting equipment, and discloses a universal portal crane which comprises a supporting leg frame, main beam frames are fixedly installed at the top of the supporting leg frame, electric rollers are fixedly installed between the adjacent main beam frames, steel wire ropes are fixedly connected to the outer surfaces of the electric rollers, and lifting tools are fixedly connected to the tail ends of the steel wire ropes. An anti-falling mechanism is arranged in the center of the steel wire rope, and a mounting seat is arranged above the lifting appliance. Firstly, a heavy object of a lifting appliance is lifted, in the lifting process, a limiting rope is continuously wound under the action of a bundling disc, when the topmost end is lifted, the limiting rope on the surface of the bundling disc makes contact with a piston plate, resin in a storage barrel is extruded into a sleeve, the resin gradually flows down to be combined with a seam of a steel wire rope stained with water, and the resin is solidified after being mixed with white water; and meanwhile, the limiting ropes on the two sides of the bottom of the mounting base are tensioned in a triangular shape, so that the situation that the overall hoisting effect is affected due to continuous shaking in the hoisting process is avoided.
本发明涉及起重设备技术领域,且公开了一种通用门式起重机,包括支腿架,所述支腿架的顶部固定安装有主梁框,相邻所述主梁框之间固定安装有电动辊,所述电动辊的外表面固定连接有钢丝绳,所述钢丝绳的末端固定连接有吊具,所述钢丝绳的中心处设置有防坠机构,所述吊具的上方设置有安装座。首先将吊具的重物抬升,在抬升的过程中,限位绳在捆盘的作用下不断缠绕,提升最顶端时捆盘表面限位绳接触活塞板,将储筒中树脂挤压至套筒内部,树脂逐渐流下与沾有水分的钢丝绳的开缝结合,利用树脂跟白水混合之后会使树脂固化,从而使加强末端的钢丝绳的强度,同时安装座底部两侧的限位绳以三角状拉紧,避免在提升过程中持续晃动,影响整体的吊运效果。
