Embodiment 1

[0022] figure 1 The three-dimensional view and partial cross-sectional view of the balance weight of the iron casting 4 and the steel casting 5 are shown. The construction machinery balance weight has a balance weight box 1 of different material grades cast by iron casting 4 or steel casting 5. The balance weight box The body 1 is provided with a filling port 2 and an air outlet 7. The filling port 2 is used for the counterweight 3 to enter the box 1, and the air outlet 7 is used for the heat gas discharged from the counterweight 3 entering the counterweight box 1 to achieve The counterweight 3 is full of the box body 1, and the metal parts steel bar 6 can be set in the counterweight box body 1 to increase the strength and toughness of the engineering machinery. After the balance weight box 1 needs to be warmed and preheated, put the counterweight 3 into the box 1 from the filling port 2, the counterweight 3 can be used for metal ore, iron ore can be used for steel slag, and m...

Embodiment 2

[0024] figure 2 The side view and partial cross-sectional view of the balance weight of the iron casting 4 and the steel casting 5 are shown. The construction machinery balance weight has a balance weight box 1 of different material grades cast by iron castings 4 or steel castings 5. The balance weight The box body 1 is provided with a filling port 2 and an air outlet hole 7. The filling port 2 is used for the counterweight 3 to enter the box body 1, and the air outlet hole 7 is used for the heat gas discharge of the counterweight 3 entering the counterweight box 1. When the counterweight 3 is full of the box body 1, a metal piece steel bar 6 can be arranged in the counterweight box body 1 to increase the strength and toughness of the engineering machinery. After the balance weight box 1 needs to be warmed and preheated, put the counterweight 3 into the box 1 from the filling port 2, the counterweight 3 can be used for metal ore, iron ore can be used for steel slag, and metal...

Embodiment 3

[0026] image 3 Shown are the front view and partial cross-sectional view of the balance weight of the iron casting 4 and the steel casting 5. The balance weight of the engineering machinery has the balance weight box 1 of different material grades cast by the iron casting 4 or the steel casting 5. In the balance weight The different reserved parts of the box body 1 are closed by welding steel plates on the upper and lower planes, and metal parts steel bars 6 and steel plates 8 are used to weld the balance weight box body 1 into one body in the cast steel box body. The metal parts pre-buried and cast on the inner wall of the cast iron box are used to weld the metal parts steel bars 6 and steel plates 8 with the balance weight box 1 into one. Fill the counterweight 3 into the counterweight box 1, the counterweight 3 can use metal ore, iron ore can use steel slag, and can be melted into metal liquid with metal blocks to fill the box 1 and add metal and non-metallic Metal ore or...

Abstract

A balance block for engineering machinery, which is made of iron castings of different material grades, cast steel box body, filling port and air outlet are set on the box body, metal parts, steel bars, hot filling accessories of different materials are set in the box body Heavy objects constitute construction machinery balance weights of various weights. In terms of quality, the engineering machinery balance block manufactured by using the invention improves the product quality compared with the prior art engineering machinery cast iron balance block. Economically, it reduces production costs, saves steel resources, reduces smelting energy consumption, and achieves the effect of energy saving and emission reduction.

Description

technical field [0001] The invention relates to a construction machinery balance block Background technique [0002] In engineering machinery such as forklifts, excavators, loaders, road rollers, rotary drilling piling machines, cranes, machine tool bases, large-scale mechanical equipment bed, bases, oil fields, elevators and other construction machinery, the weight of the balance block is required to ensure stable operation and safe use. performance. [0003] The traditional casting molding technology used in the above-mentioned balance blocks uses pig iron blocks and scrap iron and steel, uses coke, electric smelting into molten iron, and sand-casting cast iron castings. Production costs are high. [0004] The steel plate structure technology used in the above-mentioned balance weight adopts steel plate stamping forming and welding into a box body. The surface of the welded box is uneven, making it difficult to manufacture rounded corners and concave-convex characters, ...
