Walking type engineering machinery and temperature-control system thereof

Abstract

The invention discloses a temperature-control system of a walking type engineering machinery. The system comprises an engine water tank and a water pump; besides, the system also comprises a plurality of radiators, which are correspondingly arranged in a plurality of spaces in which temperatures are to be adjusted; in addition, the plurality of radiators, the engine water tank and the water pump are connected through pipelines to form a water supply loop. According to the invention, an influence on a working temperature of a sensing element in an alpine area can be effectively overcome; and an applicable range of environment of a walking type excavator is substantially improved on the basis that comfortableness of a driver in work is ensured. Preferably, the system also comprises: a system controller, which is configured to receive a control instruction or a feedback signal and output a plurality of control signals; and a direction control valve set, which is arranged in a water supply loop that is between the water pump and the radiators as well as is configured to response a selection signal among the plurality of signals of the system controller and to make commutation so as tomake a passage way between the water pump and the corresponding radiator be communicated. On the basis of the above-mentioned arrangement of the system, the invention also provides a walking type engineering machinery that applies the temperature-control system.

Description

technical field [0001] The invention relates to a walking construction machine, in particular to a walking construction machine and a temperature control system thereof. Background technique [0002] With its unique and simple structure, walking construction machinery can carry out excavation operations on slopes, uneven and narrow sites, and has unique operating performance. The following takes a walking excavator as an example to describe in detail. [0003] As we all know, walking excavators are widely used for afforestation on steep slopes, maintenance of rivers and beaches, amphibious operations in swamps, forest logging in mountainous areas, railway maintenance, etc.; when natural disasters such as avalanches and flash floods occur, they can also participate in rescue and recovery work . Based on the complex and changeable working conditions faced by walking excavators, compared with other excavator models, it is almost difficult to meet the logistic support conditio...

AI Technical Summary

Problems solved by technology

In general, effective temperature control cannot be carried out on other key parts

[0005] In addition, the water pump in this scheme uses a fixed-speed rotating motor, and its control method does not achieve energy-saving effects

Moreover, since the entire system does not have the function of multi-point deflation, the working stability of the cooling circuit is poor
