Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The utility model mainly relates to a lifting appliance for a die steel heat treatment furnace inlet and outlet, which comprises an I-shaped lifting frame 1, a bearing lifting beam 2 and a die steel lifting chain 3, as shown in figures 1-5.
The hanger comprises an I-shaped hanger 1 and a horizontal hanger 11 with an I-shaped main body, wherein the horizontal hanger 11 is provided with short beams at two ends and relatively long span beams connected with the two ends, and the length of the span beams is about 1.5-3 times that of the short beams. The horizontal hanger 11 is provided with more than 2 lifting rings 12, and is connected to lifting hooks of a travelling crane through a lifting cable 13, so that the horizontal hanger 11 is in a horizontal state. A plurality of upper transfer lifting rings 14 are arranged below the horizontal hanging bracket 11, and the upper transfer lifting rings 14 are positioned below the short frame beam and symmetrically arranged along the cross frame beam. The lower part of the upper transfer hoisting ring 14 is connected with the suspension beam 2.
The main body of the suspension beam 2 is a long-strip-shaped load-bearing cross beam 21 which is preferably an I-shaped beam, namely the cross section is I-shaped; a plurality of lower transfer rings 22 are arranged above the bearing cross beam 21, and transfer hoisting cables 23 are connected between the lower transfer rings 22 and the upper transfer rings 14. A plurality of die steel lifting rings 24 are arranged below the bearing cross beam 21, and the die steel lifting chains 3 are connected below the die steel lifting rings 24.
The die steel suspension chain 3 is a steel chain, and two ends of the steel chain are connected to the die steel suspension ring 24 below the bearing cross beam 21 to form a U-shaped suspension space for suspending the die steel.
The lifting appliance for the heat treatment of the die steel to enter and exit the furnace is different from the existing steel chain or steel cable lifting appliance in that the side length of the I shape of the horizontal lifting appliance 11 is different, and the distance between 2 bearing cross beams 21 can be adjusted by adjusting the relative position relationship between the lower bearing cross beam 21 and the lower bearing cross beam, so that the lifting appliance is suitable for die steel with different lengths; further, a plurality of upper transfer rings 14 and a plurality of lower transfer rings 22 are provided; when the length of the hoisting target die steel is short, the bearing cross beam 21 can be arranged perpendicular to the short frame beam, the lower part of the intermediate hoisting cable 23 is connected to the lower intermediate hoisting ring 22 on the outermost side of the bearing cross beam 21, the upper part of the intermediate hoisting cable 23 is connected to the upper intermediate hoisting ring 14 below the short frame beam, and the corresponding upper intermediate hoisting ring 14 is selected for installation according to the specific length of the die steel, as shown in fig. 1 and 2, so that the distance between 2 bearing cross beams 21 is different to adapt to die steels with different lengths; and when the length of the hoisting target die steel is longer, as shown in fig. 3 and 4, the bearing cross beam 21 is parallel to the short frame beam, and at this time, the transfer hoisting cable 23 can select the upper transfer hoisting ring 14 and the lower transfer hoisting ring 22 with the same spacing position to be connected, as shown in fig. 3, the upper transfer hoisting ring and the lower transfer hoisting ring at two ends can be selected to be connected, or the upper transfer hoisting ring and the lower transfer hoisting ring in the middle can be selected to be connected, and several rings can be arranged according to the reliability requirement, so that the length of the cross frame beam is the same between 2 bearing cross beams 21, so as to adapt to the relatively longer die steel.
A plurality of die steel lifting rings 24 are also arranged below the bearing cross beam 21, so that on one hand, the die steel lifting rings 24 with different intervals can be selected to install the die steel lifting chain 3 according to the cross section size of a lifting target die steel, and thus the die steel with different cross section sizes is matched; meanwhile, when the cross section size of the die steel is small and the weight of the corresponding die steel is relatively light, more than 2 die steel suspension chains 3 are installed below each bearing cross beam 21 as shown in fig. 2, so that more than 2 die steels can be lifted at the same time. Because the die steel needs to enter and exit the heat treatment trolley furnace and is not suitable for being directly attached together for hoisting (if the die steel is attached together for hoisting, the die steel has the following adverse effects that if the die steel enters the furnace, the attachment surfaces of the die steel and the die steel cannot meet the surface heat treatment requirement, so that the quality is unqualified; by adopting the utility model, at least 1 mould steel sling chain 3 is arranged between 2 mould steels, so that the mould steels are not completely attached together, and higher hoisting efficiency can be realized.
The mould steel sling chain 3 is adopted, can be self-adaptive to different cross sections, has a certain anti-skidding function for chain links, has higher hoisting reliability, and can be used for hoisting mould steel with different cross sections.
