Description

Technical Field

[0001] The utility model relates to the technical field of engineering vehicle components, in particular to a counterweight component for an engineering mechanical vehicle. Background Art

[0002] Construction machinery vehicles refer to heavy machinery used in civil engineering construction, road construction, mining and other engineering activities. They usually include excavators, loaders, rollers, cranes, bulldozers, pavers and other types, and the counterweight assembly for construction machinery vehicles usually refers to an additional component specially designed to adjust the stability, balance or carrying capacity of construction machinery vehicles.

[0003] Common counterweight assemblies for construction machinery vehicles are integral plate-shaped or block-shaped structures, which are installed at corresponding positions of construction vehicles by bolts or welding when in use. However, this method requires adjustment of the counterweight blocks under different working conditions and requirements. For example, some counterweight blocks can be installed on the arms of excavators to increase stability during excavation; while some adjustable counterweight devices can change the weight distribution as needed to adapt to different load requirements. This results in the integral counterweight assembly being inconvenient to carry and unload during disassembly and replacement due to its own heavy weight, resulting in the counterweight assembly being very inconvenient to use and having poor adaptability, and failing to meet the working requirements of the counterweight assembly. Therefore, a counterweight assembly for construction machinery vehicles is proposed. Utility Model Content

Triangular reinforcing ribs are welded between the left and right sides of the rear of the assembly set and the upper surface of the base plate, which improves the strength of the assembly set.

[0013] Preferably, limit horizontal bars are installed on the upper parts of the left and right sides of the assembly column, which can lock the assembly column and cooperate with the limit paddles to complete the installation of the assembly column. The inner lower side of the assembly column is screwed with a limit bolt, and through holes are opened at positions corresponding to the limit bolts on the inner and outer sides of the assembly sleeve.

[0014] Preferably, the outer circumference of the rotating shaft is provided with slots at positions corresponding to the limiting bolts, and the inner ends of the limiting bolts are provided with ball heads, and the limiting bolts can be inserted into the slots by rotating them, thereby limiting the rotating shaft.

[0015] Preferably, both left and right ends of the limit paddle are rounded, and the length of the limit paddle is the same as the diagonal length of the inner cavity of the assembly set, so that the assembly column can be limited when the limit paddle is horizontal, and the assembly column can be pulled out when it is tilted, which facilitates the rapid disassembly and assembly of the counterweight frame.
