The mechanical arm of the mechanical arm vehicle for replacing the actuator cylinder of the simulator adopts the existing mechanical arm with 7 degrees of freedom, simulates the arm of a human, not only provides 6 degrees of freedom (three-dimensional position) of linear motion in the directions of three orthogonal coordinate axes of x, y and z in space and 6 degrees of freedom (three-dimensional rotation) of rotational freedom around the coordinate axes, but also adds one degree of freedom to solve the problem that the mechanical arm cannot be changed from one configuration to another configuration under the condition of keeping the three-dimensional position of a tail end mechanism unchanged in space.
In order to enable the mechanical arm to flexibly rotate, the mechanical arm joint adopts a structure formed by the conventional power type rotary joints, is similar to a human arm, is formed by combining a rotating shaft and a gear at each joint, drives a speed reducer through a brushless direct current servo motor and then drives the rotating shaft and the gear to move, so that the rotation of the joints is realized, and the relative angular displacement of each adjacent part of the arm is a motion coordinate. The joint and the joint are in cooperative motion through chain transmission, the servo motor at the joint at the bottom of the mechanical arm firstly receives a driving signal to start motion, then drives gears and rotating shafts on other joints to rotate, and the brushless direct current servo motor in each joint feeds back a control result to other joints in real time after receiving respective control signals, so that the integral cooperative motion is realized. In addition, considering that the driving force is insufficient when the mechanical arm is driven by only electric power when grabbing the actuating cylinder, a hydraulic driving mechanism is added between each joint by referring to the mechanical arm of the existing working vehicle, and the hydraulic driving mechanism is composed of a driving system consisting of a hydraulic motor (an oil cylinder and an oil motor), a servo valve, an oil pump, an oil tank and the like, and drives an execution mechanism to work in an electro-hydraulic hybrid mode.
The clamping, loosening and rotation of the mechanical arm are controlled through a PLC control module. The PLC control module receives input signals (including starting, stopping, limiting instructions, sensor signal instructions and the like) from the outside, controls the double-coil two-position electromagnetic valve to control the clamping and the loosening of the mechanical arm, and controls the brushless direct-current servo motor to control the rotation of the mechanical arm. The tail end actuating mechanism of the mechanical arm is provided with a pressure sensor and an ultrasonic sensor, a pressure sensor module monitors the pressure of the current tail end actuating mechanism of the mechanical arm in real time and feeds back a pressure signal to a PLC control module, the ultrasonic sensor measures the variation of the distance from the tail end actuating mechanism to an object in real time and feeds back a distance signal to the PLC control module, the PLC control module processes the received two signals at the moment and then sends corresponding control signals for clamping or loosening the mechanical arm. When the object is extruded and slips, the PLC control module sends a control instruction after a sensor of the terminal actuating mechanism feeds back a signal in time, the limiter can limit the action of the mechanical arm immediately, and meanwhile, the sensor sends an alarm to prompt that the current movement of an operator is out of limit, so that potential safety hazards exist. In addition, the outside of robotic arm has also installed the multiunit sensor and has surveyed the module, and the purpose is the current position of real-time supervision robotic arm to avoid colliding with the analog machine in work and taking place, cause unnecessary economic loss.
The mechanical arm takes a trolley chassis as a carrier, the trolley chassis is provided with enough balance weight to prevent the situation that the gravity center of the mechanical arm shifts when the mechanical arm grabs a heavy object, the wheels are wheels of an engineering vehicle, and an axle of a heavy engineering vehicle is taken as a connecting rod to sufficiently bear the total weight of the mechanical arm vehicle and an actuating cylinder, so that the situation that the axle is broken when the heavy object is grabbed is avoided. In order to keep the center of gravity of the chassis, four hydraulic support columns (two hydraulic support columns are symmetrically arranged on the left and right sides) are arranged on the periphery of the chassis, so that the whole stress area of the chassis can be increased, and the stability of the chassis is facilitated. And in consideration of safety, the periphery of the chassis is provided with the PCR radar sensor and the infrared sensor, the two sensors actually monitor the surrounding environment condition of the trolley, and when an obstacle or a person passes through the trolley, the sensors send out an alarm at the first time and feed back signals to the safety control module, so that the current movement with harm is stopped. The mechanical arm vehicle for replacing the actuating cylinder takes alternating current as a power source, on one hand, the alternating current directly supplies power for driving a chassis of the vehicle, and on the other hand, the driving power module is utilized to convert the input alternating current into direct current to supply to the brushless direct current servo motor of the mechanical arm. The electric power of clean energy and renewable energy is used as a driving source, which is beneficial to environmental protection and prevents the harmful gas from being sucked by field workers and the damage to the field workers caused by the serious noise of the traditional diesel engine.
The mechanical arm vehicle for replacing the actuator cylinder of the simulator is remotely controlled by an operator through the handle, sends a control signal through the infrared transmitter on the handle and receives the control signal through the infrared receiver on the chassis of the trolley, so that remote control is realized. Meanwhile, the trolley is also provided with an infrared emitter, so that safety warning signals such as overrun of a chassis and a mechanical arm of the trolley can be displayed on the operating handle, and warning prompts are sent to operating personnel at the first time.
Although the replacement of the actuator of the simulator is generally arranged at night when the flight training is less, the infrared receiving head with strong light interference resistance is particularly used in consideration of the influence of sunlight when the actuator is replaced in the daytime. Since the optimum receiving wavelength of the infrared receiving head is 940nm, 940nm wavelength infrared transmitting tubes are used as infrared transmitters of the trolley and the remote control handle, and meanwhile, 38kHz carrier frequency is loaded at the transmitting end. In order to better receive infrared signals without saturation caused by strong sunlight, the infrared receiver is additionally provided with a lens hood to prevent sunlight from directly irradiating the infrared receiving head and an optical filter for filtering redundant light, thereby realizing that only light waves with the wavelength of 940nm are received. Therefore, the reliability of transmission and interaction of control signals and feedback signals between the remote control handle and the mechanical arm vehicle is greatly improved.
In order to prevent non-professionals from touching the remote control handle by mistake, a password activated operation mode is specially arranged on the remote control handle, if and only after the password is correctly input, the mechanical arm vehicle can be operated, and meanwhile, a safety prompt that the non-professionals do not need to operate is sent out before entering a password input interface, so that the safety of the simulator actuating cylinder replacement work is further ensured.
The remote control handle of the remote control mechanical arm vehicle is divided into a left area, a middle area and a right area, the left area is provided with an independent rocker which is responsible for controlling the movement direction of the chassis of the vehicle, and a yellow locking button and a red emergency stop button are respectively arranged below the rocker. The locking button is used for locking the movement of the trolley chassis, when an operator remotely controls the trolley chassis to a specified position, the trolley chassis does not need to move, and a locking key is arranged to lock the current state of the trolley chassis in order to prevent misoperation from touching the rocker. The emergency stop button is used for emergently stopping the current movement of the trolley chassis due to the fact that the trolley chassis cannot accurately detect or feed back a danger signal in an emergency situation, and an operator can stop all movement of the trolley for safety at the first time so as to avoid accidents. The middle area of the remote control handle is provided with a display screen and digital keys, the current state of the mechanical arm vehicle and the alarm signal synchronous with the sensor module can be displayed through the display screen, and therefore the real-time control of the mechanical arm and the chassis of the trolley by a control person can be better assisted. The number keys are used for inputting a password for activating the handle to work and selecting a preset instruction, so that operation of an operator can be facilitated, and the operation difficulty is reduced. The middle area is also provided with a switch of a remote control handle, the remote control handle can be started by one key, and the communication between the remote control handle and the mechanical arm vehicle is activated at the same time, so that the mechanical arm vehicle enters an initial working state; after the work is finished, the remote control handle can be disconnected from the mechanical arm vehicle, and the remote control handle is closed. The right area is designed similarly to the left area, and has a separate rocker which controls the direction of movement of the robot arm, under which a yellow lock button and a red emergency stop button are also provided. The locking button is used for locking the movement of the mechanical arm, when an operator remotely controls the mechanical arm to a designated position, the mechanical arm does not need to move, and a locking key is arranged to lock the current state of the mechanical arm in order to prevent misoperation from touching the rocker. The emergency stop button is used to emergency stop the current movement of the robot arm, because the sensor module on the robot arm fails to accurately detect or feedback the danger signal in an emergency, and the operator can stop all the movements of the robot arm for the first time to avoid accidents for safety.
Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the invention and the appended claims, and therefore the scope of the invention is not limited to the disclosure of the embodiments and the accompanying drawings.
