Embodiment Construction
[0035] The core of the present invention is to provide a rescue traction system for a walking excavator, which can realize rescue traction operations under complex terrain conditions. Another core of the present invention is to provide a walking excavator including the above-mentioned rescue traction system.
[0036] The orientation words such as front and rear involved in this article are defined based on the normal working state of the walking excavator. It should be understood that the orientation words used in this article should not limit the protection scope of this patent.
[0037] Under mountainous conditions, walking excavators need four wheels and two front paws for six-point ground contact. The front paws need to be fixed and supported at a fixed position below the steep slope to achieve body stability, and the fixed anchor points are often located behind the body. , in order to realize the docking with the fixed anchor point, it is necessary to hook the traction ro...

The invention discloses a walking type excavator and a rescue traction system thereof. The rescue traction device is used for dragging the walking type excavator to move towards a fixing anchor point on a steep slope terrain and comprises a hydraulic winch and a movable pulley component, the hydraulic winch is mounted on a base plate, one end of the fixed pulley component is provided with a movable pulley while the other end of the movable pulley component is provided with a connecting hook, a traction hook of the hydraulic winch is wound around the movable pulley to be fixedly connected with the base plate, and the connecting hook is connected with the fixing anchor point. By the aid of the movable pulley component, a rope between the traction hook and the movable pulley and a rope between the movable pulley and the hydraulic winch are switched via the movable pulley and simultaneously bear traction force, the purpose of simultaneous traction by the double ropes is realized, force on each rope is halved, tension carried by the ropes is reduced, traction capacity of the integral excavator is improved, safety of the walking type excavator is guaranteed, and applicability of the walking type excavator is enhanced.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a rescue traction system for a walking excavator. In addition, the present invention also relates to a walking excavator comprising the above-mentioned rescue traction system. Background technique [0002] 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 disasters such as avalanches and flash floods occur, they can also participate in emergency recovery work and so on. [0003] Compared with other types of excavators, the working environment of walking excavators has a strong ability to adapt to the terrain, and it can work on terrains where other types of excavators cannot work. In the case of large terrain gradients such as mountains, grasslands, and woodlands, the weight of the excavator nee...
