Technical Field

The application relates to the technical field of aircraft manufacturing, in particular to a remote control underneath driving type group overturning guardrail.

Background

In aircraft production, often because the great personnel of aircraft size are difficult to reach the operating position, need set up work platform and provide basic working face for personnel, and the guardrail is the essential personnel safety protection structure of work platform. In production, because an airplane needs to enter and exit a station and needs to keep a safe distance with a working platform, the guardrail is often designed to be a turnover guardrail or a plug guardrail, when the airplane enters and exits the station, the turnover guardrail is turned over or the plug guardrail is pulled down to vacate a sufficient height space to ensure that the airplane can safely enter and exit, and when the airplane is in the station, the turnover guardrail is turned up or the plug guardrail is inserted to ensure personnel safety. However, on one hand, with rapid progress of science and technology, automation and intellectualization become a great trend of tool development, and original manpower-dependent guardrail overturning and guardrail plugging and unplugging cannot be connected to an automation system, so that the basic requirements of tool automation and intellectualization are difficult to meet; on the other hand, in actual production, because large aircraft size is great, lead to the work platform size also often great, its length can reach tens meters, and its height can reach more than ten meters, so no matter overturn the guardrail or plug the guardrail quantity all very much. Plug guardrail operating personnel need one insert or extract the plug guardrail when the field usage, the upset guardrail needs an upset, work load is very big, operating time is longer, and the upset guardrail is at the upset in-process, just there is cliff formula border when the upset guardrail is overturned the rear platform, because operating personnel still is at work platform cliff formula border position, the operating personnel risk of falling this moment is very big, the plug guardrail also has the potential safety hazard similar with the upset guardrail, in addition the plug guardrail is at the in-process of plug, because the frictional force of plug guardrail and platform is unstable, there is the sense of setover in the plug in-process, stand and need discontinuity power application at cliff formula border department operating personnel, make operating personnel operation potential safety hazard further increase.

For a working platform in the manufacturing process of a large airplane, a reversible protective guard which is high in safety, small in operation workload and capable of being connected to an automatic system for remote control is needed.

In order to achieve the above purpose, the following technical scheme is adopted to realize the purpose:

a remote control underneath driving type group overturning guardrail comprises a guardrail group, a basic table board, a hinge, a telescopic device, a remote control system and a pin shaft, wherein the guardrail group is connected to the side surface of the basic table board through the hinge between the guardrail group and the basic table board, the telescopic device is arranged below the basic table board, one end of the telescopic device is connected to the lower side surface of the basic table board through the pin shaft, the other end of the telescopic device is connected to the lower side surface of the guardrail group through the pin shaft, when the guardrail group needs to be erected, a person controls the telescopic device to retract through the remote control system to drive the guardrail group to rotate around the basic table board by taking the hinge as a rotation center, when the guardrail group rotates to an erected state, the telescopic device stops stretching, the guardrail group is erected vertically vertical to the basic table board at the moment, when the guardrail needs to be overturned, the person controls the telescopic device to stretch out through the remote control system to drive the guardrail group to rotate around the basic table board by taking the hinge as a rotation center, when the guardrail group rotates to the turnover state, the telescopic device stops stretching, and the guardrail group is turned over to be parallel to the base table board.

The guardrail crowd is by whole base, crank the arm, a plurality of move and bump contact receptacle and a plurality of guardrail and constitute, and whole base is rectangular shape overall structure, and crank the arm appearance and be L shape, and crank arm upper end and whole base fixed connection, the other end are provided with the connecting hole, move and bump contact receptacle in whole base below and whole base fixed connection, and the several guardrail is frame-type protective structure, whole base and several guardrail fixed connection.

The base is fork ear-shaped structure, is provided with the connecting hole matched with the telescopic device, the base and the static touch seat are fixedly connected with the platform table frame below the platform table, and when the guardrail group rotates to a standing state, the movable touch seat just touches the static touch seat.

The telescopic device can be divided into an extension part and a fixed part, connecting holes are formed in the end head of the extension part and the tail end of the fixed part, the connecting hole in the end head of the extension part of the telescopic device is hinged to the connecting hole in the end head of the crank arm on the guardrail group through a pin shaft, and the connecting hole in the tail end of the fixed part of the telescopic device is hinged to the base below the base table board through a pin shaft.

The advantage of this application lies in comparing traditional upset guardrail and plug guardrail, and its security is high, the operation work load is little, save operating time.

The present application will be described in further detail with reference to the following drawings and examples.
