Abstract
The utility model discloses a device capable of improving operation intuitiveness of walk of an excavator. Electromagnetic valves are added and arranged in guide oil circuits between walk guide valves and walk motor control valves, a position sensor is arranged on a lower frame of the excavator, and an upper frame is provided with a trigger which is matched with the position sensor. An intelligent walk module button control opening and closing of the trigger, an output signal of the trigger is converted into a signal which can be distinguished by the electromagnetic valves through a converter and controls the electromagnetic valves to reserve, and a flow direction of an original guide oil circuit is changed by the revering of the electromagnetic valves so as to enable a driver to be satisfied with a forward direction operation way when the driver operates the walk of the excavator, namely, the excavator goes forward when the driver pushes a walk pushing rod forward and the excavator draws backward when the driver pulls the walk pushing rod backward. Therefore, inconvenience that the driver judges the walk direction in advance when operating the walk of the excavator is avoided, potential safety hazard caused by tentative operation is avoided, and operation intuitiveness and working efficiency are improved.
Description
Technical field
The utility model relates to a kind of control device of excavator, specifically a kind of device that improves excavator walking operation intuitive.
Background technology
Hydraulic crawler excavator is a kind of main Types of engineering machinery, is the main mechanical of earthwork evacuation, is widely used in industry and the departments such as civilian construction, road and bridge, municipal engineering, irrigation and water conservancy.Hydraulic crawler excavator generally partly is comprised of equipment, slewing equipment, running gear and hydraulic control device etc.Usually, equipment and hydraulic control device are installed on the vehicle frame, are called upper body, and running gear is installed on the lower vehicle frame and is called lower body, and upper body is connected by slewing equipment with lower body, can be around fixing axis of rotation rotating 360 degrees.When equipment and running motor during in centre of gyration both sides, be called positive direction.This moment, the driver promoted forward the push rod of walking, and excavator advances, and pulls back the walking push rod, and excavator retreats, and should be the positive operation mode; When equipment and running motor during at centre of gyration homonymy, be called in the other direction.This moment, the driver promoted forward the push rod of walking, and excavator retreats, and pulls back the walking push rod, and excavator advances, and should be the reverse operating mode.
Because excavator can turn round by 360 degree, so excavator may be walked forward when promoting forward the walking push rod, also may walk backward.Usually, the driver observes the position of running motor by cab window, also there are a lot of producers to post direction prompting symbol at the guide wheel interior plate, but for mini-excavator, because the relative driver's cabin overhang of side bar of both sides, chassis is shorter, the driver is sitting in position that can't see running motor in the driver's cabin.For medium-and-large-sized excavator, because the swing arm position, also may have influence on the visual angle of driver's observation running motor, and excavator works in the operating mode rugged environment usually, lower vehicle frame is usually covered by mud and the position that can't tell running motor.At present, the driver takes tentative operation walking push rod to judge direction of travel usually in a lot of situations, so not only for driver's operation makes troubles, affects comfort level, loses time, has also brought certain potential safety hazard for operation.
