Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy casting, in particular to a casting lifting and hoisting mechanism for a semi - continuous casting machine in a melting and casting workshop. Background Technique

[0002] The melting and casting workshop is a place for producing finished cast ingots. During the process of producing cast ingots, there are technological processes such as batching → melting → adjusting composition and temperature → on - line refining and filtering → casting → sawing, etc. The production equipment, auxiliary production equipment and material stacking used are all concentrated in the melting and casting workshop.

[0003] After the casting is completed on the vertical semi - continuous casting machine, the crane operator in the workshop needs to operate the crane that meets the lifting requirements in the workshop to lift the casting out of the casting well and place it in the storage area or directly lift it onto the sawing machine.

[0004] However, quite a number of enterprises, in order to reduce investment, need to utilize existing old factories or standard factories built by the government. Such factories often do not have a crane or do not have a crane tonnage that can meet the requirements of lifting the ingots. Therefore, a structure and layout method is needed to enable the processes of lifting and transporting the ingots to proceed smoothly. If the factory building that cannot meet the requirements of ingot lifting is to be renovated, generally, both the above - ground and underground parts of the casting and sawing areas of the entire factory building need to be renovated. This renovation requires relatively complete construction drawings and needs to be appraised by a professional structural appraisal of the existing situation of the factory building. Only after comprehensive consideration can the renovation plan be determined and implemented. Generally, it requires a large investment, is time - consuming and laborious, and at the same time, the renovation of the old factory building itself may also pose safety hazards. For this reason, we propose a casting lifting and hoisting mechanism for a semi - continuous casting machine in a melting and casting workshop. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a casting lifting and hoisting mechanism for a semi - continuous casting machine in a melting and casting workshop. When there is no crane in the workshop or the original crane cannot meet the requirements of ingot lifting, this structure is used to complete the lifting and transportation of the casting, avoiding large - area renovation of the factory building, reducing the renovation cost while meeting the production requirements, saving time and effort, and avoiding the safety hazards caused by the renovation of the old factory building, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A casting lifting and hoisting mechanism for a semi - continuous casting machine in a melting and casting workshop, including a furnace body arranged in the melting and casting workshop and a vertical semi - continuous casting machine connected to the furnace body. A sawing machine loading table is arranged outside the furnace body and the vertical semi - continuous casting machine. A number of columns are evenly and symmetrically arranged on both sides of the vertical semi - continuous casting machine. A crane track is installed at the top of the columns, and a crane for lifting the casting is arranged on the crane track.

[0007] As a preferred technical solution of the present utility model, the pillar includes a pillar body, a bottom plate is arranged at the bottom end of the pillar body, and a pre-embedded column buried in the underground concrete is arranged on the lower surface of the bottom plate.

[0008] As a preferred technical solution of the present utility model, a plurality of connecting plates are uniformly arranged on the circumferential side surface of the lower part of the pre-embedded column, and a connecting ring is fixedly arranged at the bottom end of the connecting plate.

[0009] As a preferred technical solution of the present utility model, through holes are respectively formed at the four corners of the upper surface of the bottom plate, pre-embedded bolts buried in the underground concrete are arranged in the through holes, and the top ends of the pre-embedded bolts penetrate through the through holes and are threadedly connected with nuts.

[0010] As a preferred technical solution of the present utility model, a plurality of reinforcing rib plates are uniformly arranged between the outer side surface of the bottom of the pillar body and the upper surface of the bottom plate.

[0011] As a preferred technical solution of the present utility model, a bracket for assisting in supporting the overhead crane track is arranged on the side surface of the top end of the pillar body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: Two rows of pillars are arranged on both sides of the vertical semi-continuous casting machine along the ingot hoisting direction. The pillars support the overhead crane track, and the height of the overhead crane track can meet the requirements of the ingot hoisting height. At the same time, an overhead crane that can meet the requirements of the ingot hoisting tonnage and working level is configured on the track. During operation, the operator hoists the ingot from the ingot well through the overhead crane, and then transports the ingot to the loading table of the sawing machine covered by the overhead crane track, completing the hoisting and transfer of the ingot. This solves the problem of hoisting and transferring the ingot in the ingot well in a workshop without an overhead crane or with an overhead crane that does not meet the hoisting requirements. At the same time, it avoids large-area renovation of the workshop, does not require time-consuming and laborious searching for a complete set of drawings and professional structures to identify the existing situation of the workshop, reduces costs, saves time, and can perform the lifting and hoisting of the ingot for a single ingot well or two adjacent ingot wells without affecting the operations around the ingot well.
