Abstract

The invention discloses a radiation-resisting mechanical arm. A mechanism for carrying out pitching motion comprises a rotary joint arm A and a rotary joint arm B. The upper portion of the rotary joint arm A is connected with the lower portion of the rotary joint arm B. The rotary joint arm A is provided with a common working servo motor a. The common working servo motor a is connected with a gearin a motor backup gear box, the gear in the motor backup gear box is connected with a coupler, the coupler is connected with a worm and worm wheel mechanism, the worm and worm wheel mechanism is connected with a hollow type harmonic reducer, the hollow type harmonic reducer is connected with the rotary joint arm B, and therefore the common working servo motor is rotated to drive the rotary jointarm B to do pitching motion. A mechanism for carrying out horizontal motion comprises a rotary joint arm C and a rotary joint arm D. The rotary joint arm C drives a straight gear drive mechanism 9 through a common working servo motor b, and the straight gear drive mechanism drives the rotary joint arm D to rotate.

Description

technical field [0001] The invention belongs to the field of mechanical arms, and in particular relates to a radiation-resistant mechanical arm. Background technique [0002] The present invention aims to design a novel radiation-resistant mechanical arm. It has the functions of real-time monitoring, on-site video image acquisition, etc., and has the ability to complete remote operation, sensor data acquisition and transmission tasks in semi-enclosed environmental conditions with high radiation and complex spatial location distribution. This requires: when the mechanical arm breaks down during use, it should be easy to maintain on site and leave the site environment; the mechanical arm has a simple structure, small size, compact structure, can carry related instruments, and the on-site operation time should be as short as possible to avoid on-site maintenance and ensure Zero failure rate. According to the research results, the structure, control accuracy, operating environ...
