Abstract
The utility model discloses an anticollision safety device for the tail of an excavator, comprising an ultrasonic wave sensor, a travelling pressure switch, a main controller, a cab display and a pilot electromagnetic valve, wherein the ultrasonic wave sensor and the main controller are connected by virtue of a serial port RS232, the cab display and the main controller are connected by virtue of a CAN (controller area network) bus, one end of a coil of the pilot electromagnetic valve is connected to the main controller, the other end of the coil of the pilot electromagnetic valve is grounded, the main controller controls the pilot electromagnetic valve, one end of the travelling pressure switch is grounded, and the other end of the travelling pressure switch is connected to the main controller. According to the anticollision safety device for the tail of the excavator disclosed by the utility model, a pilot oil circuit of the excavator is controlled by acquiring a distance signal of the ultrasonic wave sensor, and collision at the tail of the excavator caused by rotation or travelling is avoided; and the anticollision safety device for the tail of the excavator disclosed by the utility model has the advantages of high practicability, good safety and convenience in user operation.
Description
Technical field
The utility model relates to a kind of excavator, relates in particular to a kind of afterbody anticollision device, collision-prevention device of excavator, belongs to the engineering mechanical device technical field.
Background technology
In the practice of construction operation, be sitting in the driver's cabin because handle the digging machine hand of excavator, often the visual field can only be seen the place ahead and see the situation of side by rearview mirror, can only be by virtue of experience to operate for rear counterweight part bit position control.Thereby the situation that the excavator afterbody bumped in when work is difficult to avoid, and causes the damage of excavator and near personnel security threat.Also there are some excavators to configure post-positioned pick-up head on the market, but are shown as the master with imaging, do not participate in control.In order to guarantee safety, so that excavator afterbody in walking and rotating process does not strike pedestrian or obstruction, the afterbody anticollision device, collision-prevention device that develops a kind of excavator is very necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of excavator afterbody anticollision safety device, solves the technical problem that the excavator afterbody bumps when work.
A kind of excavator afterbody anticollision safety device, comprise ultrasonic sensor 1, walking pressure switch 2, master controller 3, driver's cabin display 4, pilot solenoid valve 5, connect by serial ports RS232 between described ultrasonic sensor 1 and the master controller 3, driver's cabin display 4 is connected with master controller by the connection of CAN bus, the coil one of described pilot solenoid valve 5 is connected to master controller 3, other end ground connection, 3 pairs of pilot solenoid valves 5 of master controller are controlled, one end ground connection of described walking pressure switch 2, the other end is connected to master controller 3.
Compared with prior art, the beneficial effects of the utility model are: by the distance signal that gathers ultrasonic sensor guide's oil circuit of excavator is controlled, avoided because turning round or walking and cause the collision of excavator afterbody.Have the advantages such as practicality is high, safety good, user-friendly.
Description of drawings
Fig. 1 is circuit structure diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.As shown in Figure 1, the utility model comprises ultrasonic sensor 1, walking pressure switch 2, master controller 3, driver's cabin display 4, pilot solenoid valve 5, connect by serial ports RS232 between described ultrasonic sensor 1 and the master controller 3, driver's cabin display 4 is connected with master controller by the connection of CAN bus, the coil one of described pilot solenoid valve 5 is connected to master controller 3, other end ground connection, 3 pairs of pilot solenoid valves 5 of master controller are controlled, one end ground connection of described walking pressure switch 2, the other end is connected to master controller 3.
Described ultrasonic sensor 1 is contained on the counterweight of excavator afterbody, the situation of excavator afterbody is carried out 360 ° monitoring, and sends range information to master controller 3.
Counterweight is within 0.5 meter detect the obstacle distance of excavator afterbody when ultrasonic sensor 1 after, and then driver's cabin display 4 has the alarm signal flicker.
Detect when ultrasonic sensor 1 behind the obstacle distance of excavator afterbody within 0.2 meter of the counterweight, then master controller 3 is immediately with pilot solenoid valve 5 outages, at this moment excavator can not carry out any revolution, walking or other actions, and driver's cabin display 4 can eject a dialog box " warning: will bump against rear obstacle ".At this moment, press " OK " key on the bridge instrumentation, pilot solenoid valve 5 can restore electricity, and then the driver can adjust the excavator position.
If excavator can only be worked under such environment, then press " ESC " on the bridge instrumentation strong after, close this excavator afterbody anticollision safety system, the warning dialog box can not eject.Until walking pressure switch 2 has detected after the walking action, this security system can restart execution.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
