Description

TECHNICAL FIELD

[0001] The utility model relates to a molten steel casting technology field especially relates to a fork type molten steel pouring trolley that can adapt to different specifications. BACKGROUND

[0002] Molten steel ladle and molten steel pouring have various types due to process needs, one of which is a bottom pouring type molten steel ladle with a plug rod, the plug rod can be moved by a manual pressing rod or a servo mechanism or other means outside the mechanism, thereby controlling the opening and closing of the bottom molten steel nozzle and the pouring speed, at present, when the bottom pouring operation of the molten steel ladle is carried out, the molten steel ladle is often lifted by a hoisting device or is operated using a dedicated molten steel pouring trolley, this way has the following deficiencies in the actual use process:

[0003] 1. The hoisting machine lifting method not only needs to bundle and fix the molten steel ladle, but also the molten steel ladle is prone to swing during lifting, especially when the staff carries out the bottom pouring operation, the swing of the molten steel ladle has a great safety hazard;

[0004] 2. When the bottom pouring operation of the molten steel ladle is carried out on the molten steel pouring trolley, the molten steel ladle is often fixedly installed on the molten steel pouring trolley, due to the irregular structure of the molten steel ladle, the molten steel ladle cannot be seated on the conventional movable molten steel pouring trolley, or after being seated, the plug rod cannot be controlled to pour due to the interference between the plug rod and the structure on the molten steel pouring trolley, resulting in that the existing molten steel pouring trolley has a narrow application range and cannot meet the bottom pouring operation of molten steel ladles of different specifications;

[0005] 3. The existing molten steel ladle has an upper end open structure, when the bottom pouring operation is carried out, the molten steel pouring takes a long time, which leads to the rapid heat dissipation of the molten steel in the molten steel ladle, affecting the subsequent molten steel pouring operation;

[0006] Therefore, there is an urgent need for a fork type molten steel pouring trolley that can overcome the above deficiencies. UTILITY MODEL CONTENTS

[0007] In order to overcome the deficiencies in the background art, the utility model discloses a fork type molten steel pouring trolley that can adapt to different specifications, the utility model not only can conveniently and efficiently heat preservation load transport molten steel ladles of different specifications, but also greatly facilitates the staff to carry out the bottom pouring operation of the molten steel ladle.

[0008] To achieve the above purpose, the utility model adopts the following technical scheme:

[0009] A forklift-type steel pouring car adaptable to different specifications includes a traveling trolley composed of a bridge frame, end beams, and a first traveling mechanism. The bridge frame is provided with a track arranged along the axial direction of the bridge frame. The traveling trolley is provided with a translation trolley that travels along the track and has a rectangular frame structure. The translation trolley is provided with a sunken movable frame that can be raised and lowered and has a hollow box structure.

[0013] Furthermore, the sunken movable frame includes two parallel longitudinal bars, which are fixedly connected by several cross bars. The two longitudinal bars are perpendicular to the main beam, and both ends of the longitudinal bars are connected to the output end of the lifting cylinder. Several side bars are provided at the bottom of the two longitudinal bars, which are perpendicular to the longitudinal bars and arranged in an orderly manner along the axial direction of the longitudinal bars. Two steel ladle seats are respectively installed on the lower part of the opposite surface of the side bars.

[0014] Furthermore, the main beam is provided with a guide wheel on the side facing the sunken movable frame, which can rotate along the lifting direction of the sunken movable frame. The side rod of the sunken movable frame corresponding to the guide wheel is provided with a guide rod that cooperates with the guide wheel.

[0015] Furthermore, one end of the opposite face of several side rods is provided with a limiting rod that cooperates with the ladle seat and is used to lock and limit one end of the molten steel ladle.

[0016] Furthermore, the lower part of the crossbar inside the sunken movable frame is provided with a guide column perpendicular to the crossbar. The cover is fixedly connected to the lower end of the column inside the guide column. An electric cylinder is provided on one side of the sunken movable frame.

[0017] Furthermore, one side of the sunken movable frame is equipped with an operating platform with a quadrilateral frame structure, and the bottom surface of the operating platform is a liftable structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are: by operating the large trolley and moving the small trolley, the molten steel ladle can be transported conveniently and efficiently, avoiding the traditional hoisting method of lifting equipment;

[0019] By setting up a ladle holder, not only can the molten steel ladle be loaded and transported securely and stably, but different specifications of molten steel ladles can also be loaded and transported by changing the ladle holder.

[0020] By setting up a retractable and adjustable sunken mobile frame, it is much more convenient for subsequent staff to perform bottom pouring of molten steel in the ladle;

[0021] By setting up a ladle cover, the molten steel inside the ladle can be effectively kept warm, preventing the molten steel from losing heat and cooling down, which provides strong support for subsequent molten steel pouring operations;

[0022] This invention not only enables convenient and efficient heat-insulated loading and transportation of molten steel ladles of different specifications, but also greatly facilitates the subsequent bottom pouring operation of the molten steel ladle, providing strong support for the molten steel pouring operation.

[0031] Example 1: A forklift-type steel casting trolley adaptable to different specifications includes a traveling trolley 1 composed of a bridge frame 8, end beams 10, and a first traveling mechanism 11. The bridge frame 8 is provided with a track 7 arranged along its axial direction. The traveling trolley 1 is provided with a translation trolley 2, which travels along the track 7 and has a rectangular frame structure. The translation trolley 2 includes two main beams 4 and two secondary beams 5. The two main beams 4 are arranged in parallel and corresponding directions, and their opposite ends are fixedly connected by the secondary beams 5. A second traveling mechanism 9, adapted to the track 7, is provided at the lower part of the two main beams 4. The second traveling mechanism 9 is similar to that of a traditional crane. The same traveling mechanism is used for the translation trolley 2. The translation trolley 2 is equipped with a sunken movable frame 3 with a hollow box structure that can be raised and lowered. Specifically, the sunken movable frame 3 includes two parallel and corresponding longitudinal rods 12. The two longitudinal rods 12 are fixedly connected by several cross rods 13. The lower part of each of the two longitudinal rods 12 is provided with several side rods 14 that are perpendicular to the longitudinal rods 12 and are arranged in an orderly manner along the axial direction of the longitudinal rods 12. The lower sides of the inner cavity of the sunken movable frame 3 are provided with corresponding steel ladle seats 15 for loading and fixing molten steel ladles. The two steel ladle seats 15 are respectively installed on the lower part of the opposite surface of the side rods 14. The two longitudinal rods 12 are perpendicular to the main beam 4 and the two ends of the longitudinal rods 12 are respectively located on the upper part of the two longitudinal rods 12. The upper part of each of the two longitudinal rods 12 is provided with two lifting cylinders 6 that are respectively corresponding to the ends of the two longitudinal rods 12. The output end of the lifting cylinder 6 is connected to the end of the longitudinal rod 12.

[0032] In Example 2, during the transportation and pouring of molten steel, in order to keep the molten steel inside the ladle warm, the inner cavity of the sunken movable frame 3 is equipped with a liftable and adjustable ladle cover 23 for sealing and heat preservation of the molten steel. Specifically, the lower part of the crossbar 13 in the sunken movable frame 3 is provided with a guide post 22 perpendicular to the crossbar 13.
