Counterweight device for heavy equipment

Abstract

The invention discloses a counterweight device for heavy equipment. The counterweight device is of concave structure; a water guiding groove is formed at the contact position of a counterweight body and an engine cover; a sealing strip is arranged inside the water guiding groove; a beam mounting seat for mounting a beam is arranged on the inner side wall of the counterweight body; a gas spring mounting seat A is arranged at the inner side wall of the counterweight body and is connected with a gas spring joint; a mounting seat is arranged on a frame; the counterweight body is fixed onto the mounting seat; and the two ends of the beam are correspondingly fixed onto the mounting seat arranged on the frame. According to the counterweight device, the general assembly of the engine hood and thecounterweight body is achieved; the abrasion, breakage and breakdown of lockset are eliminated; the deformation, breakage and breakdown of a door frame caused by the reaction force of a gas spring areeliminated; the sealing property is good; the rainwater and mud are prone to be removed; and the functions of bubbles formed at paint surfaces and the damage of electrical components in an engine compartment are eliminated.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a counterweight device for heavy equipment. Background technique [0002] Construction machinery is an important part of the equipment industry. Generally speaking, the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and unloading operations, and various construction projects is called As construction machinery, it is mainly used in national defense construction projects, transportation construction, energy industry construction and production, mining and other raw material industry construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection and other fields. [0003] Generally speaking, heavy equipment such as small and medi...

AI Technical Summary

Problems solved by technology

[0004] The following problems exist: 1. The engine cover and the counterweight are installed independently, the assembly process is poor, the gap between the cover and the counterweight is difficult to guarantee, and the vibration frequency of the counterweight and the engine cover is different during the operation of the equipment, resulting in premature damage to the mating contact and locks. Fracture; 2. One end of the gas spring is arranged on the door frame, and the other end is arranged on the engine hood. The force arm is small and the nominal force is large, which causes a large reaction force on the door frame and the engine hood, deforming or partially breaking the door frame and the engine hood. ;3. There is no water guide groove at the contact between the engine cover and the counterweight, rainwater will flow into the engine compartment, damage electrical components, and local water accumulation will cause the paint surface of the parts to peel
