[0012] Figure 2 This is the overall installation diagram of the utility model. DETAILED DESCRIPTION

[0013] like Figure 1 and 2 The casting ladle molten iron weighing structure shown includes a traveling roller 1, an elevator 2 and a ladle mechanism 3, wherein the traveling roller 1 is connected to the upper end of the elevator 2, and the ladle mechanism 3 is connected to the lower end of the elevator, and the ladle mechanism 3 is driven to move by the traveling roller 1.

[0014] An electronic scale 4 is provided between the traveling roller 1 and the elevator 2, and the upper and lower weighing components of the electronic scale 4 are respectively connected to weigh the molten iron below. The electronic scale 4 is a wireless electronic scale, and the weight of the molten iron is read through a wireless display screen.

[0015] The electronic scale used in this embodiment is a wireless electronic scale of suitable size purchased on the market. The original hook and hanging ears are removed, and the original hook part of the electronic scale is modified to replace the original connecting head of the ladle. The height of the center of the ladle handwheel from the casting platform cannot be changed by 1.5m, and the operation cannot be affected.

[0016] The electronic scale 4 includes a scale body 401 and upper and lower weighing components.

[0017] A connecting knife 101 is provided under the traveling roller 1, and the upper weighing component of the electronic scale is an upper fixed support rod 402. The upper fixed support rod 402 has a vertical groove for inserting the connecting knife 101. The connecting knife 101 and the upper fixed support rod 402 have multiple sets of screw holes correspondingly provided. After the connecting knife 101 is inserted into the vertical groove of the upper fixed support rod 402, the two are fixed through the screw holes.

[0018] The top of the elevator 2 is an inverted U-shaped steel member 201, and the top of the U-shaped steel member 201 has a hole; the lower weighing component of the electronic scale 4 is a lower fixed support rod 403, and the lower fixed support rod 403 is outerly provided with a channel steel 404, and is bolted through corresponding screw holes passing through the two, and a threaded support rod 405 is provided at the bottom of the channel steel 404, and the threaded support rod 405 is vertically penetrated through the top hole of the U-shaped steel member 201 and connected to the fixed head, which only limits the axial position of the threaded support rod 405, and does not limit its circumferential free rotation.
