Description

Technical Field

[0001] The invention relates to the technical field of RGV transfer, in particular to a multifunctional RGV for transporting materials toward a furnace mouth. Background Art

[0002] In the field of boiler factories, materials need to be transported to different boilers; especially in a small factory site, there are often two groups of opposing boilers set up opposite each other. In order to solve the problem of boiler feeding, RGV trolleys are needed to transport materials in the site.

[0003] The existing problems are: 1) Due to the small distance between the two boilers in the site, the RGV trolley in the site cannot turn around on the spot, so multiple trolleys are needed to cooperate in the transfer.

[0004] 2) There are multiple slopes in the site, which makes it inconvenient for the existing RGV trolley to move. For example, if one RGV trolley is used to transport materials under the same slope, the trolley is not suitable for use across sites with different slopes, which increases the number of trolleys required.

[0005] 3) When the trolley in the site is transferred to the furnace mouth, since the trolley does not have the function of picking up and delivering materials, when it walks to the conveyor line at the furnace mouth, it is necessary to be equipped with a special person to unload the materials onto the conveyor roller line to complete the loading, which is inefficient.
