The invention discloses a double-hook portal crane which comprises a supporting rod, a hoisting mechanism is arranged at the upper end of the supporting rod and comprises a sliding rail fixedly arranged at the upper end of the supporting rod, a sliding frame is arranged on the outer side of the sliding rail in a sliding mode, hoisting equipment is installed at the upper end of the sliding frame, and a lifting device is fixedly arranged at the rear end of the supporting rod. A supporting frame is fixedly arranged at the upper end, and a connecting frame is fixedly arranged at the front end of the supporting frame. According to the double-hook portal crane, a second gear and a first gear are driven by a third gear to rotate in different directions, so that a secondary gear and a main gear push a second gear plate and a first gear plate to move in different reverse directions, and the purpose of conveniently pulling two sets of hoisting equipment to move towards the middle position of a supporting rod is achieved; and the moving distances of the two sets of hoisting equipment are ensured to be the same, so that the two sets of hoisting equipment can be ensured to be positioned right above the object.

    本发明公开了一种双钩门式起重机,包括支撑杆,所述支撑杆的上端设置有起重机构,所述起重机构包括固定设置在支撑杆上端的滑轨,所述滑轨的外侧滑动设置有滑架,所述滑架的上端安装有起重设备,所述支撑杆的后端固定设置有,所述的上端固定设置有支撑架,所述支撑架的前端固定设置有连接架。本发明所述的一种双钩门式起重机,通过三号齿轮带动二号齿轮、一号齿轮分别以不同方向进行旋转故而使副齿轮、主齿轮分别以不同反向推动第二齿轮板、第一齿轮板移动达到便于拉动两组起重设备向支撑杆中间位置移动的目的,且保证两组起重设备移动的距离相同,故而可以保证两组起重设备位于物品的正上方。
