Abstract
The utility model relates to a safety device capable of preventing an excavator from hitting a person, belonging to the technical field of the excavator. The safety device comprises a controller arranged on the excavator, a sensor positioned on the excavator, and an alarm device arranged in a driving cab, wherein the alarm device and the sensor are respectively and electrically connected with the controller by a control circuit. The safety device has the beneficial effects that a human body infrared sensor is respectively added at each of the left rear part, the right rear part and just the rear part of the excavator; the driving cab is internally provided with a buzzer; when someone passes nearby the excavator, signals are transmitted into the controller of the excavator by the human body infrared sensors, so that an electromagnetic valve is closed by the controller of the excavator, a pilot oil way is immediately cut off, a control handle of the excavator is invalid, and the excavator immediately stops working; and meanwhile, the buzzer arranged in the driving cab sounds so as to prompt a driver that someone passes nearby the excavator.
Description
Technical field
The utility model relates to a kind of safety device of thrusting into of preventing, specifically is a kind of safety device that prevents that excavator from thrusting into, and belongs to the excavator technical field.
Background technology
Excavator is a kind of common engineering machinery, is widely used in the place of various earthworks.The excavator thing of in operation process, thrusting into often has generation in recent years, and main cause is can't see the excavator left back when tractor driver operates excavator, right back and dead astern.If a kind of safety device is installed on excavator, force the excavator break-off as the people automatically during near excavator, will improve the safety of excavator when operation greatly like this.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of safety device that prevents that excavator from thrusting into, and forces excavator break-off, safety and reliability when improving excavator operation during near excavator automatically as the people.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of safety device that prevents that excavator from thrusting into; Comprise the controller that is installed on the excavator; Also comprise the sensor that is installed on the excavator, and be installed in the warning device in the driver's cabin, warning device and sensor are electrically connected with controller through control circuit respectively;
Further, sensor is the human-body infrared sensing device;
Further, sensor has 3, is installed on excavator left back, right back and dead astern respectively;
Further, warning device is a buzzer.
The beneficial effect of the utility model is: respectively install a human infrared sensor additional in left back, right back and the dead astern of excavator; A buzzer is installed in driver's cabin; Man-hour is arranged near excavator, and human infrared sensor will be transferred to controller for excavators with signal, and controller for excavators will cut off the closed electromagnetic valve of guide's oil circuit at once; The control crank of excavator will lose efficacy; Excavator will quit work at once, and the buzzer in the driver's cabin sounds simultaneously, near the prompting tractor driver excavator people is arranged.
Description of drawings
Fig. 1 is the schematic diagram of the safety device that prevents that excavator from thrusting into.
Among the figure: 1. main pump, 2. pioneer pump, 3. controller, 4. electromagnetic valve, 5. warning device, 6. human-body infrared sensing device.
The specific embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
As shown in Figure 1, a kind of safety device that prevents that excavator from thrusting into by controller 3 and 3 sensors 6 of being installed on the excavator, and is installed in the warning device 5 in the driver's cabin, and warning device 5 is electrically connected with controller 3 through control circuit respectively with sensor 6.
Said warning device 5 is buzzers.
During the excavator operate as normal; Electromagnetic valve 4 is in open mode, and the oil of pioneer pump 2 flows to control crank through electromagnetic valve 4, and tractor driver's manipulation handle is accomplished the control at main valve; Thereby the oil that makes main pump 1 flows to each executing agency of excavator, and excavator is accomplished exercises under tractor driver's operation.
Said sensor 6 is the human body infrared sensor; Its maximum magnitude that can detect is 7 meters; Be installed on excavator left back, right back and dead astern respectively; In three human infrared sensor any one detects has man-hour near excavator, all can this signal be transferred to controller 3, and controller 3 cuts out electromagnetic valve 4 at once.The oil that flows to control crank is cut off; Control crank can't be controlled main valve, and the oil of main pump 1 just can not flow to each executing agency of excavator through main valve, and excavator quits work; The buzzer of controller 3 drive installations simultaneously in driver's cabin has the people near the prompting tractor driver excavator.
After near the people leaves excavator; The human-body infrared sensing device that is installed on excavator left rear side, right lateral side and dead astern does not all detect when people or thing being arranged near the excavator, and sensor 6 is transferred to controller 3 with this signal, and controller 3 is opened electromagnetic valve 4 at once; The oil that flows to control crank is switched on; Control crank is controlled main valve, and the oil of main pump 1 flows to each executing agency of excavator through main valve, and excavator is resumed work; Controller 3 stops to drive buzzer simultaneously, and the tractor driver continues the normal running excavator.
Claims (4)
1. safety device that prevents that excavator from thrusting into; Comprise the controller (3) that is installed on the excavator; It is characterized in that; Also comprise the sensor (6) that is installed on the excavator, and be installed in the warning device (5) in the driver's cabin, warning device (5) and sensor (6) are electrically connected with controller (3) through control circuit respectively.
2. a kind of safety device that prevents that excavator from thrusting into according to claim 1 is characterized in that described sensor (6) is the human-body infrared sensing device.
3. a kind of safety device that prevents that excavator from thrusting into according to claim 1 and 2 is characterized in that described sensor (6) has 3, is installed on excavator left back, right back and dead astern respectively.
4. a kind of safety device that prevents that excavator from thrusting into according to claim 1 is characterized in that described warning device (5) is a buzzer.
