Energy accumulator arrangement structure and excavator

Abstract

The invention discloses an energy accumulator arrangement structure. The energy accumulator arrangement structure comprises a rotary platform, an energy accumulator and a balance weight component, wherein the balance weight component is fixed to the tail end of the rotary platform through a fastener. The energy accumulator arrangement structure is characterized in that the energy accumulator is also fixed to the tail end of the rotary platform; the balance weight component is provided with an accommodating space for accommodating the energy accumulator; and when the balance weight component is unloaded or mounted relative to the rotary platform, the energy accumulator fixed to the rotary platform does not interfere with the balance weight component. By the adoption of the technical scheme, a traditional excavator can be transformed into an energy-saving excavator very conveniently, the rotary platform, a covering part and the like do not need to be redesigned, and a large amount of cost and time are saved; and the energy accumulator is arranged at the tail end of the rotary platform, and an oil way between a multi-way valve and the energy accumulator does not need to be disassembled when the balance weight component is disassembled, so that the problems of transportation and assembly are well solved.

Description

technical field [0001] The invention relates to an accumulator layout structure and an excavator, belonging to the technical field of excavators. Background technique [0002] In recent years, in response to major issues such as the global energy crisis and environmental pollution, energy-saving excavators have been increasingly favored by users and affirmed by enterprises. [0003] The basic principle of the energy-saving excavator is: the gravitational potential energy dropped by the working device is recovered through the boom cylinder and converted into hydraulic energy. The hydraulic energy enters the accumulator through the energy-saving valve, and the energy is finally stored in the high-pressure cylinder. When lifting again, the capacity in the accumulator is released to the boom to lift, and this cycle is repeated to reduce the lifting load of the working device, reduce the power output of the engine, and achieve the purpose of energy saving. [0004] Therefore, co...

Problems solved by technology

However, according to road transportation requirements, in some cases, large excavators need to disassemble the counterweight components for transportation. If the accumulator is fixed in the counterweight component, the hydraulic oil circuit connected to the accumulator needs to be disassembled when removing the counterweight. It is easy to cause environmental pollution, and it is very difficult to disassemble and assemble
