Description

Technical Field

[0001] The utility model relates to the technical field of molten steel casting auxiliary devices, in particular to a quick-change trolley used for replacing a bottom leak casting bag plug rod during steel casting. Background Art

[0002] When the mechanical manufacturing foundry uses the V-method to cast steel parts (such as the production of cast steel bridge shells), the traditional teapot ladle cannot be used for slag blocking during pouring due to the high melting point, fast solidification and poor fluidity of cast steel. If a flat-mouth ladle is used, slag blocking cotton can be placed at the pouring nozzle to block the slag, but the slag blocking cotton is easy to float and move during the pouring process, and the slag blocking effect is not ideal. Therefore, a bottom-leaking ladle with a water outlet at the bottom of the ladle is generally used. Because the molten steel slag is light and floats on the liquid surface, it can prevent the molten steel slag from being brought into the mold during pouring, and can effectively prevent slag hole defects in the casting. Under normal production conditions, the plug rod of the bottom-leaking ladle needs to be replaced every 10 furnaces; if there are abnormal conditions such as molten steel leaking or the plug rod breaking, the plug rod must be replaced at any time. The existing problems are: on the one hand, the plug rod weighs more than 20 kilograms, and the bottom leakage casting ladle is large and deep, so it is not easy to remove and install the plug rod; on the other hand, it is necessary to ensure that the old plug rod is not broken after being removed so that it can be reused after rework, which increases the difficulty of plug rod replacement. Therefore, it is necessary to develop a trolley that can quickly assist in replacing the plug rod to receive and feed materials. Summary of the invention

[0003] The utility model aims to provide a bottom drain pouring bag plug rod quick-changing trolley for cast steel, which has a simple and compact structure, low manufacturing cost, and is easy and efficient to use, so as to realize the convenient and rapid connection and disassembly of the old plug rod and the feeding and installation of the new plug rod when replacing the bottom drain pouring bag plug rod in the casting production of steel castings.

[0004] To achieve the above purpose, the utility model of a quick-change trolley for bottom-leak pouring plug rod for cast steel includes a material receiving trough 1, a main frame, a tool storage rack 5, a handrail 7 and wheels; the main frame is welded by four vertical pipes 2 and eight horizontal pipes 4 to form a rectangular structure, and the vertical pipes 2 and the horizontal pipes 4 are both seamless square pipes; the material receiving trough 1 is a long channel steel, which is fixed to the left and right horizontal pipes 4 on the top of the main frame by square pipe welding, and one end thereof extends outward in a cantilever shape; the tool storage rack 5 is welded to the bottom of the main frame; the wheels include two universal wheels 6 and two fixed wheels 3, which are respectively welded to the horizontal pipes 4 on both sides of the bottom of the main frame; the handrail 7 is welded to the upper horizontal pipe 4 at the rear end of the main frame.

[0005] The utility model of a quick-changing trolley for bottom leak pouring package plug rod for cast steel has the following technical features and beneficial effects:

[0006] 1. After the old plug rod is removed, the material can be safely connected without falling or being damaged, and the new plug rod can be fed and installed. The operation is convenient and quick, which solves the problem of difficulty in removing and installing the plug rod due to the heavy weight of the plug rod and the deep bottom of the bottom leakage casting bag during the replacement of the bottom leakage casting bag plug rod during the casting of steel castings.

[0007] 2. The structure is simple and compact, the production cost is low, and it is easy and efficient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The specific implementation method of the utility model of the quick-changing trolley for the bottom leakage pouring package plug rod for cast steel is further described in detail below in conjunction with the accompanying drawings.

[0013] Figure 1 to Figure 3 As shown, the utility model of the bottom leakage pouring bag plug rod quick-change trolley for cast steel comprises a material receiving trough 1, a main frame, a tool storage rack 5, a handrail 7 and wheels; the main frame is welded by four vertical pipes 2 and eight horizontal pipes 4 to form a rectangular structure, and the vertical pipes 2 and the horizontal pipes 4 are seamless square pipes; the material receiving trough 1 is a long channel steel, which is fixed to the left and right horizontal pipes 4 on the top of the main frame by square pipe welding, and one end thereof extends outward in a cantilever shape, and the function of the material receiving trough 1 is to place the disassembled old plug rod and the new plug rod for feeding; the tool storage rack 5 is welded to the bottom of the main frame for placing tools and materials; the wheels comprise two universal wheels 6 and two directional wheels 3, which are respectively welded to the horizontal pipes 4 on both sides of the bottom of the main frame, so that the quick-change trolley can realize the function of free rolling movement and time-saving and labor-saving; the handrail 7 is welded to the upper horizontal pipe 4 at the rear end of the main frame for the trolley pushing and steering operation.

[0014] When removing the old plug rod, first lay the bottom leakage pouring ladle horizontally on the tooling frame, then point the front end of the material receiving trough 1 of the quick-change trolley toward the ladle, push the material receiving trough 1 of the trolley to just below the old plug rod, and after the nut of the old plug rod is removed, it falls into the material receiving trough 1 and is taken away; when installing the new plug rod, place the new plug rod on the material receiving trough 1, push the trolley, send the new plug rod into the ladle, install it and lock it.

[0015] The utility model solves the problem that the plug rod is heavy and it is difficult to manually take out materials, feed materials and install them, and can ensure that the plug rod will not be damaged due to falling, thereby achieving the purpose of saving time and effort in replacing the plug rod.
