The invention relates to a tire portal crane which comprises a hoisting assembly, a module car set and a support, the hoisting assembly comprises a first portal frame and a second portal frame which are symmetrically arranged, a cross beam arranged between the top of the first portal frame and the top of the second portal frame, a lifting appliance connected to the cross beam and a power station, and the support is arranged at the bottom of the first portal frame and the bottom of the second portal frame. The bottom of the support is provided with a space capable of containing the module car set, the module car set is detachably arranged in the space of the bottom of the support, and the module car set can ascend and descend in the vertical direction to drive the support and the hoisting assembly to ascend and descend in the vertical direction. The modular car group is detachably connected, so that the modular car group can be suitable for different tire portal cranes, the problem that each tire portal crane needs to be independently equipped with the modular car group is solved, the cost is greatly reduced, the use of the tire portal cranes can be more widely promoted, the production efficiency is improved, the structure is simple, and the operation is convenient.
本发明涉及一种轮胎门式起重机,包括起重组件、模块车组以及支架,起重组件包括对称设置的第一门架和第二门架、设置在第一门架和第二门架顶部之间的横梁、连接在横梁上的吊具以及动力站,支架设置在第一门架、第二门架的底部,支架的底部具有可容纳模块车组的空间,模块车组可拆卸地设置在支架的底部的空间内,模块车组可沿竖直方向升降,带动支架、起重组件沿竖直方向升降。本发明通过将模块车组设置为可拆卸地连接,使得模块车组可适用于不同的轮胎门式起重机,解决了每个轮胎门式起重机需单独配备模块车组得问题,极大降低了成本,可更广泛的推动轮胎门式起重机的使用,提高了生产效率,且结构简单,操作方便。
