A three-degree-of-freedom robotic arm for assisting in the disassembly and assembly of radar blocks

Abstract

The invention discloses a fetching-assisting three-degree-of-freedom mechanical arm used for assembly and disassembly of radar blocks. The fetching-assisting three-degree-of-freedom mechanical arm used for assembly and disassembly of the radar blocks comprises a telescopic arm, a telescopic handle, a driving handle, a transmission shaft, a turning gearbox and a buckle mechanism, wherein the telescopic handle is used for controlling the telescopic arm to stretch or retreat; the turning gearbox is arranged at the head end of the telescopic arm, and the buckle mechanism is arranged in the turninggearbox; the transmission shaft is located at the bottom of the telescopic arm, a first straight gear is fixed to one end of the transmission shaft, and a bevel gear engaged with bevel teeth is fixedto the other end of the transmission shaft; the driving handle is arranged at the bottom of the transmission shaft, and a second straight gear is fixed to the end of the driving handle; and when thetelescopic arm stretches out, the transmission shaft is driven to move towards the head end to enable the first straight gear to be opposite to and engaged with the second straight gear, the driving handle is rotated, then the second straight gear drives the first straight gear and the transmission shaft to rotate, and the turning gearbox turns. The fetching-assisting three-degree-of-freedom mechanical arm used for assembly and disassembly of the radar blocks is simple in structure, small in size and convenient to carry and operate; and upper connectors of the radar blocks can be connected rapidly and conveniently in use, and the radar blocks can be disassembled from the mechanical arm easily.

Description

technical field [0001] The invention relates to the technical field of radar block disassembly and assembly, in particular to a three-degree-of-freedom mechanical arm for assisting in the removal and assembly of radar blocks. Background technique [0002] With the development of machinery, mechanical devices are becoming more and more diverse, and their structures are becoming more and more sophisticated, and it is becoming more and more common to use mechanical devices to solve problems in life. Mechanical devices can help people do some work, save manpower, and can also replace people to complete many jobs that cannot be done by humans. [0003] The existing radar device is composed of a large number of radar blocks. When installing and dismounting the radar blocks, people cannot approach the operation, so it is troublesome to rely on manual work. Therefore, there is a need for a device that can take and install or disassemble the radar block, and the structure of the dev...

Problems solved by technology

[0004] Restricted by the environment and working conditions of use, there are restrictions on the weight and size of the machine used, but currently there are few such machines with complex structures and large volumes, which are not conducive to other subsequent operations

Those that can realize electric automatic operation need a power supply, which is not easy to carry and use anytime and anywhere, and the repair and maintenance are more cumbersome
