Abstract
A method and safety device for a vehicle wash tunnel with a support structure with two parallel rails for the placement, by means of corresponding carriages, of the arms of an arch which incorporates a horizontal brush capable of linear movement along the arms of the arch and the rails. The safety device includes a rotation shaft, for fastening the arms of the arch to the carriages, and an extendable cylinder, spaced from the rotation shaft, which joins each carriage to the corresponding arch, such that the arch can rotate with respect to the carriages, and the extension of the extendable cylinder causes the rotation of the arch.
Claims4
A safety device for a vehicle wash tunnel comprising:
- a support structure with two parallel rails for the placement by means of corresponding carriages of the arms of an arch which incorporates a horizontal brush for washing the vehicle, capable of linear movement along the arms of the arch and the rails,
- a rotation shaft integral with each carriage for fastening each arm of the corresponding arch;
- and
- an extendable cylinder spaced from each rotation shaft which joins each carriage to the arch by means of supports whereon it can rotate, wherein the arch is capable of rotating with respect to the carriages and the extension of the extendable cylinder causes the rotation of the arch and a locking device further comprising:
- a locking hook integral with one carriage, capable of tilting;
- and
- an interlocking support integral with the arch;
- wherein the rotation of the arch causes the contact of the interlocking support with the locking hook, which tilts until it reaches a limit position wherein it loses contact with the interlocking support in order to move on to lock it and, with it, the movement of the arch, which is retained.
