Reverse self-locking servo electric cylinder and launching device thereof

Abstract

The invention provides a reverse self-locking servo electric cylinder and a launching device thereof, and belongs to the technical field of launching devices. The reverse self-locking servo electric cylinder comprises a motor, a gearbox and a reverse locking mechanism. The motor is arranged on one side of the gearbox and drives the gearbox to rotate; the reverse locking mechanism comprises a driving ring, a driven ring and a shell, and the driving ring and the driven ring are arranged in the shell; the gearbox is in transmission connection with the driving ring, the driving ring is connected with the driven ring, the driven ring is rotationally arranged in the shell through rotation of the driving ring, and the other end of the driven ring is connected with the lead screw; an open groove is formed between the driven ring and the shell, and a pin roller is arranged between the driving ring and the driven ring; and the lead screw is sleeved with a cylinder rod, when the cylinder rod drives the lead screw to rotate reversely under the action of external force, the pin rollers roll into the open grooves, the driven ring is arranged in the shell in a locking mode through the pin rollers, and the driven ring and the driving ring are arranged in a reverse locking mode. Forward electric transmission and reverse self-locking are achieved, and the reliability and safety of the erecting device are ensured.

Description

technical field [0001] The invention relates to the technical field of launching devices, in particular to a reverse self-locking servo electric cylinder and a launching device thereof. Background technique [0002] The servo electric cylinder is the device on the launching device (vehicle) that drives the load to erect and return to level. When the launching device is unfolded, the servo electric cylinder is driven by the motor to extend the cylinder rod, and the driving load is erected or lifted; when the launching device is withdrawn, the servo electric cylinder is driven by the motor to retract the cylinder rod, and the driving load is realized to return flat or down. When launching, the servo electric cylinder drives the load to stabilize at a certain angle to track the target. In the above process, if the motor fails and loses power, the load will fall under the action of gravity, which may cause safety problems. [0003] At present, the usual measure is to add a po...
