Definitions

  • the present invention relates to a nacelle, in particular a lifting platform.
  • the nacelles in particular elevating ones, are well known to those skilled in this art as illustrated by the patent FR 2,909,084 .

  • This problem is perfectly known and solutions using a cable or a bar security have already been imagined to solve this problem as illustrated for example by patents EP 2 794 461 Or EP 2 096 078 which discloses the preamble to claim 1.
  • a cable or bar positioned in front of the control console allows, in the state requested by the operator, to control the stopping of the drive in movement of the platform generally by inactivation of the controls of the control system. driving movement of the platform.
  • the cable or the bar can be stressed, for example, when the operator positioned standing in front of the control console is forced to lean towards the control console until exerting pressure on the cable.
  • such solutions present a risk of getting stuck between the cable or safety bar and the obstacle, once the movement of the platform has stopped.
  • An aim of the invention is to propose a nacelle whose design makes it possible to limit the risk of the operator being trapped between the flexible safety link and the obstacle once the movement of the platform has stopped without harming the compactness of the systems. maintaining the link.
  • the or at least one of the members for detecting a deformation of the link is a member for detecting the angular position of the rotating member for winding the link of one support systems. It is thus possible to increase the travel of the link without increasing the reaction time of the detection member. It can in fact be allowed for the detection member to pass from the inactive state to the active state from the start of an angular movement of the rotary winding member of the link resulting from a deformation of the link and as a result of stopping any movement of the platform while allowing the rotary winding member of the link to continue its angular displacement stroke in the direction of unwinding of the link of the rotary winding member, including at the active state of the detection organ.
  • the platform stop command can for example be carried out at the start or in the middle of the angular displacement range of the rotary winding member of the link resulting from the deformation of the link by pressure exerted on the link without harming the continuation of the angular movement of the rotating member for winding the link in the direction of unwinding of the link.
  • the nacelle comprises a control unit with which the device for detecting a deformation of the link is configured to communicate, this control unit being configured to emit a control signal for stopping the operation of the controls of the platform movement drive system based on the data received from the detection device.
  • the or at least one of the members for detecting a deformation of the link is a sensor for detecting the angular position of the rotating member for winding the link of one maintenance systems by contact with said rotary member for winding the link or without contact, this sensor being electrically connected to the control unit and being configured to send to the control unit an electrical signal depending at least on the angular position of the rotating member for winding the link of said holding system.
  • this design of the member for detecting a deformation of the link makes it possible to act on the movement of the platform as soon as an angular movement of the rotating member for winding the link is detected without harming the continuation of the angular movement of the rotary winding member of the link in the direction of unwinding of the link of said rotary winding member so that the risk of the operator being trapped between the flexible safety link and an obstacle, an once the movement of the platform has stopped, is reduced due to the remaining travel allowing the link to be released.
  • the nacelle comprises a system for resetting the operation of the command(s) of the platform movement drive system, in the state prevented from operating the commands, this system comprising a member manually actionable reset button.
  • the reset member is configured to, in the actuated state, control the drive system to move the platform in a predefined manner to allow the operator to disengage.

  • the elastic return member of said rotating winding member is therefore configured to exert on the wheel a driving force in rotation of the wheel in the direction of winding of the link around the wheel. Pulling on the link in the direction of unwinding of the wheel link therefore makes it possible to move the wheel to which the link is coupled against the return action of the spring on the wheel.

  • the dual function of the angular stop makes it possible to limit the angular displacement of the rotary winding member of the link in all situations of deformation of the link, this deformation possibly resulting from tension of the link for example by pressure exerted on the link by the operator or a loosening of the link for example in the case of a break in the link.
  • the nacelle comprising a stop for limiting the angular movement of the rotary winding member of the link of one of the holding systems, said stop being configured to limit the angular movement of the rotary member at least in the direction of unwinding of the link of said rotating member beyond a predetermined angular displacement stroke of said rotating member, the member for detecting a deformation of the link is configured to, under the effect of a deformation of the link, moving from an inactive state to an active state in an angular position of said rotary link winding member other than the or at least one of the angular positions of said rotary link winding member corresponding to an end position of said rotating winding member materialized by said stop.
