Problems solved by technology

[0003] The purpose of the present invention is to solve the shortcomings of the existing rescue robot system such as complex system, bloated structure, high price and difficult maintenance, etc., and make a new design for each drive device of the rescue robot, integrate the detection mechanism and the drive mechanism into one, simplify the The system structure, and a clutch device is added. When the system has a torque output signal, the motor rotates. The clutch device connects the motor and the reduction gear set. The motor drives the designated part through the reduction gear set, and exerts force on the movement of the part. When When the system has no torque output signal, the motor stops rotating, and the clutch device disconnects the connection between the motor and the reduction gear set, reducing and reducing the resistance of the moving parts, making its movement smoother

specific Embodiment approach 1

[0008] Specific implementation one: as image 3 and Figure 4 As shown, the rescue robot biaxial driver includes a drive part 111, the drive part 111 includes a motor 40 and a clutch device, and the clutch device is composed of a clutch device friction plate 41, a friction plate sliding rod 42, and a return tension spring 43. 2. The clutch device cover 44 is composed of the friction plate sliding rod 42 and the shaft of the motor 40 fixedly connected. The tension spring 43 and the clutch cover 44 are inserted into the shaft of the motor 40 . The clutch cover 44 is in sliding contact with the shaft of the motor 40 . The clutch cover 44 is provided with a transmission gear. Action implementation process: when the rotational speed of the motor 40 is higher than a certain value, the two clutch device friction plates 41 overcome the pulling force of the return tension spring 43 and slide to the two ends of the friction plate sliding rod 42 respectively and contact the inner wall o...

Abstract

The invention provides a double-shaft driver of a rescue robot and relates to a driving device of a rescue robot. Through the double-shaft driver, the problems that a driving device of an existing rescue robot is too large in size, low in driving precision, single in function and low in integration level and does not have a driving and detection separation function are solved. A servo device achieving double-shaft same-direction output double-angle sensor detection is provided, the control mode of the closed-loop control of a driving motor and output shafts and closed-loop control of the output shafts and a control system is formed, and thus the control system can conduct precise motion control over motion parts of the robot. The double-shaft driver has the advantages of being reliable in performance, high in driving precision, large in torsion, fast in response, small in size, high in integration level and capable of feeding back the positions of the output shafts to the control system and the like.

Description

technical field [0001] The invention relates to a dual-axis driver of a rescue robot which has a clutch device, outputs torque on two axes, and can feed back the rotational position of the output shaft to a control system. Background technique [0002] Due to the development of science and technology, rescue robots are gradually being used in a larger and larger range. Since the 1990s, the International Advanced Robotics Program (IARP) has held many robot seminars, and rescue robots have appeared in developed countries. marketable products. At present, advanced rescue robot technology has been widely used in emergency rescue, disaster relief, and anti-terrorism. Rescue robots also have good application prospects in battlefield rescue, and are widely valued by foreign militaries. According to the latest data released by the Pentagon, the US military has killed more than 4,200 people and injured more than 31,000 people on the Iraqi battlefield. However, due to the importanc...
