Safety attachment device for two actuators

Abstract

Applicable in installations with two reaction bars attached to a first and a second piece, arranged above two actuators, also attached to the first and second piece for producing the relative displacement between both pieces. It comprises a support located between the reaction bars, fastened to them, covering at least their upper part; each reaction bar having at least one first cable, located above the surface of the support and whose ends are attached to the confronting side walls of an actuator; some vertical arms attached to the support and to two horizontal parallel bars, located between the confronting side faces of the actuators; at least one second cable located around each one of the horizontal parallel bars that are fastened to the side face of an actuator so that, when an actuator is disconnected from the first or second piece, it is kept retained by means of the device.

Description

OBJECT OF THE INVENTION[0001]The safety device of the invention is applicable to installations that are provided with actuators which are fixed to two pieces in order to produce the relative displacement between them and which require the incorporation of a standby or redundant actuator, in such a way that two actuators are provided arranged in parallel which can function simultaneously or with one of them as a standby element in the event of failure occurring in the other actuator. The safety device of the invention has the aim of permitting securing of one of the two actuators when its disconnection occurs with respect to the said pieces to which they are fixed. It is a further aim of the invention to provide a simplified, low weight, structure for the safety device.[0002]As a consequence, the invention is applicable to any sector of industry in which it is sought to prevent the total or partial falling of either of the two actuators in the event of one of them being accidentally ...

Problems solved by technology

Moreover, the safety bolts incorporate widenings at their free end in order to control the lateral movements of the actuator, this increases the weight and complexity of the safety bolts, apart from the fact that said safety bolts have to be capable of supporting the weight of the actuator in the event of disconnection.

One of the pieces to which the actuator is attached is a fixed piece, while the other one is mobile, in such a way that in the event of disconnection of the fixed piece occurring, when displacement of the mobile piece is effected, it pulls on the actuator, and with that the possible pulling movements of the actuator body are of considerable length, so large dimensioned windows need
