In the case of no conflict, the above-mentioned improvements or preferred technical solutions can be implemented alone or in combination.

In the technical solution provided by the utility model, the running main beam can move on the structural main beam, and one end of the running main beam can be moved out of the machine room, and the running main beam can also be moved and fully folded into the machine room. When one end of the running main beam moves out of the machine room, the ground equipment can be hoisted directly into the machine room. When the running main beam is moved and fully retracted into the machine room, the equipment in the machine room can be maintained or It can be folded and fixed at a certain position without affecting the operation of the portal crane. Directly relying on the lifting device of the machine room, the equipment in the machine room can be placed on the ground for maintenance or the ground equipment can be put into the machine room, thereby improving work efficiency and saving maintenance costs.

Description of drawings

The accompanying drawings are used to provide a further understanding of the utility model and constitute a part of the application. The schematic embodiments of the utility model and their descriptions are used to explain the utility model and do not constitute improper limitations to the utility model. In the attached picture:

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

The hoisting device of the portal crane machine room shown in Figure 1 and Figure 2 includes a structural main beam 1 fixed on the top of the machine room; the first roller set 2 and the second roller set 3 slide with the structural main beam 1 The running main beam 6 connected; the electric lifting device 7 slidingly connected with the running main beam 6; located near the second roller group 3 side of the first roller group 2, fixedly connected with the running main beam 6, and the structure main beam 1 The first protector 4 that is slidingly connected to the bottom surface; the second protector 5 that is located at the indoor end of the machine room of the running main beam 6 and is fixedly connected with the running main beam 6 and slidingly connected with the bottom surface of the structural main beam 1 . The two ends of the hanging cable rod 8 are respectively connected to the two ends of the running main beam 6; the power supply cable of the electric lifting device 7 is slidingly connected to the hanging cable rod 8. The ends of the first protector 4 and the second protector 5 near the structural main beam 1 are provided with rollers in contact with the structural main beam 1, the running main beam 6 can move on the structural main beam 1, and one end of the running main beam 6 can move Stretch out outside the machine room, and the running girder 6 can also be moved and all gathered in the machine room.

working principle:

The running main beam 6 is slidingly connected with the structural main beam 1 through the first roller group 2 and the second roller group 3, the running main beam 6 can move on the structural main beam 1, and one end of the running main beam 6 can move out to the machine room Outside, running girder 6 also can move all to gather in the machine room.
