Abstract

A power system and an excavator provided by the present invention relate to the technical field of excavators, and are used to improve the power of the excavator when running at high speed to a certain extent, so as to realize the rapid evacuation of the excavator in emergency situations. The power system provided by the present invention is used for construction machinery equipment, and includes a power device, a first clutch, an emergency travel pump, a multi-way valve and a start switch; the power device is connected with the multi-way valve and the first clutch respectively, and the emergency travel pump is connected with the Between the first clutch and the multi-way valve, the output ends of the multi-way valve are respectively connected with the traveling oil circuit, the working oil circuit and the auxiliary oil circuit; the start switch can control the first clutch to engage and cut off the auxiliary oil circuit.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a power system and an excavator. Background technique [0002] Hydraulic excavator is an earthmoving machine that uses hydraulic pressure to drive the compound action of each joint to excavate materials above or below the bearing surface and transfer the excavated materials. It mainly uses buckets to load and unload materials, and has been widely used in construction, industry, agricultural construction, transportation, and defense and military fields. However, in rare cases, hydraulic excavators are also used to dismantle tall chimneys, water towers, high-risk buildings, etc. In order to ensure the safety of drivers and equipment, it is necessary to quickly evacuate the site in case of danger. [0003] However, since the existing hydraulic excavator has only two speeds, it cannot meet and ensure the rapid and safe evacuation of personnel and equipment. [0004] Therefore, t...
