[0027] Figure 1-Figure 3 This is an embodiment of the present utility model. The specific problem addressed by this specific embodiment is that the frame of the trolley furnace generally adopts a frame guard plate at the bottom and a frame brick or castable at the top. Since the frame bricks have poor impact resistance, the trolley frame 2 or castable is easily crushed, which seriously affects the service life of the trolley. In response to the problem that the trolley frame 2 or castable is easily crushed, this solution proposes a solution for the trolley frame, which adopts a split type of upper frame 3 and lower frame 4, adopts different materials according to the use part, and ensures strength by encrypting the reinforcing ribs 43, effectively improving the impact resistance of the upper frame 3. At the same time, it can be replaced individually according to the wear and tear, thereby reducing the replacement cost.

[0028] A trolley frame specifically described is based on an existing trolley frame 1, and a trolley frame 2 consisting of an upper frame 3 and a lower frame 4 is installed on the upper end of the trolley frame 1. The upper frame 3 and the lower frame 4 are arranged in a stacked and docked state, and the lower frame 4 is connected to the trolley frame 1. The upper frame 3 includes a connecting frame 31 and a rib plate 32 placed inside the connecting frame 31. The arrangement of the rib plate 32 follows the internal structure of the connecting frame 31. The lower frame 4 includes an outer frame 41 connected to the connecting frame 31 and the trolley frame 1. One end of the outer frame 41 is provided with a protrusion 42 extending into the refractory fiber. One end of the outer frame 41 is offset from the mounting surface of the protrusion 42 and is provided with a side plate 48 and a reinforcing rib 43 installed on the side plate 48. A reinforcing plate 44 is installed on the outer frame 41 structure offset from the reinforcing plate 44.

[0029] The outer frame 41 structure specifically described in this embodiment has an extension body 45 extending vertically upward from the installation position of the side plate 48. The outer frame 41 includes a vertical section 411 connected to the connecting frame 31 and a horizontal section 412 connected to the trolley body. A connecting section 413 is connected between the vertical section 411 and the horizontal section 412. A protrusion 42 is provided on the vertical section 411, and a preset bolt hole 46 is provided on the horizontal section 412. The protrusion 42 and the outer frame 41 are integrally formed. The extension body 45 is embedded in the outer wall of the connecting frame 31. Preset bolt holes 46 are provided on the side plate 48 and the bottom plate of the connecting frame 31. The cross-section of the connecting frame 31 is trapezoidal, and an eaves plate 33 is provided on its top. The eaves plate 33 is flush with the casting plane, which can effectively prevent damage to the trolley frame 2 bricks or castables when hoisting the workpiece. The connecting frame 31 structure is recessed inward at the protruding position of the extension body 45, and the recessed width and height are adapted to the structural shape of the extension body 45.

[0030] The reinforcing ribs 43 specifically described in this embodiment are arranged in a conformal manner inside the outer frame 41, and their height is less than the setting height of the reinforcing plate 44 inside the outer frame 41, which plays a role in strengthening the strength of the outer frame 41. The reinforcing ribs 43 start to extend from the bottom of the side plate 48 and end at the edge of the bottom plate of the outer frame 41. The setting range of the reinforcing ribs 43 in the left and right directions covers the edge position of the outer frame 41 to form the side wall of the outer frame 41. The reinforcing plate 44 is arranged between several reinforcing ribs 43. The reinforcing plate 44 is arranged in a trapezoidal cross-section inside the outer frame 41, and a lifting hole 47 is opened on it to reduce casting defects. Anchor nails can also be installed on the reinforcing plate 44 to anchor the castable around the trolley.

[0031] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.
