Definitions

  • the present invention relates to a system for the automatic safety moving of sectional overhead doors with a hydraulic lifting.
  • Sectional overhead doors that is gates formed by horizontal sections of simple or isolated panels, are known, which are joined together by hinges, laterally provided with wheels suitable to engage one each other and to rotate within side rails, so as to guide and keep together joined the sections of the panels sliding upward during the opening.
  • the lifting of the doors can be hydraulic and, if so, it is used a lifting group essentially consisting of a hydraulic cylinder, usually positioned inside a protection and guide seat, which operates a number of lifting and transmission pulleys.
  • Such a system allows to produce panels of weight also significantly different one from each other, allowing, for example, to apply reinforcements on the lower panels, which are subject to frequent collisions and damages.
  • the system assures greater freedom of application, lower production constraints and insignificant maintenance costs with respect to the lifting systems of the springs type.
  • the safety rules in force require that the automatic mechanization system of a sectional door must be provided with a device that, in case of failure, allows the door to reach one of the ends of the stroke, and stop until the failure is repaired.
  • the main aim of the present invention is, therefore, to carry out a safety system for moving hydraulic-lifting sectional overhead doors, which, in case of failure, allows a lifting group (and, in a more general sense, to a moving group) of the sectional door to reach the end of stroke and remain stable in that position.
  • Another aim of the invention is to achieve a high safety system for moving hydraulic-lifting sectional overhead doors, which is effective, reliable and relatively inexpensive, compared to the known art.
  • the device according to the invention allows to test whether the hydraulic circuit (TU), placed between the motor-pump (M) and the hydraulic cylinder (CI), presents hydraulic oil leakages, since it is the only part of the lifting mechanism that can be damaged, due for example to collisions.
  • the sectional overhead door POR is of vertical opening type and it is synchronously raised at the two sides, typically by means of appropriate hooks AG to the lower panel PI, through the hydraulic system of moving (i.e. lifting, in this case) carried out according to the invention, which includes a hydraulic actuator cylinder CI, inserted into a motorization box CAS, placed generally above the door POR, and directly driving two cables CA1, CA2, suitably diverted by means of two respective pulleys PU1, PU2.
  • a hydraulic actuator cylinder CI inserted into a motorization box CAS, placed generally above the door POR, and directly driving two cables CA1, CA2, suitably diverted by means of two respective pulleys PU1, PU2.
  • the lifting system of the sectional door POR may also comprise a double plurality of lifting and transmission pulleys.
  • the cylinder CI is also connected with the hydraulic motor M, generally located on a wall, at human height, laterally to the door POR, through at least one pipe TU of the hydraulic circuit or motorisation MI.
  • the hydraulic circuit MI preferably uses a hydraulic pump (not shown in the attached figures), preferably driven by the hydraulic motor M, which leads the oil under pressure to the use, consisting of the hydraulic cylinder CI, for the operation of the door POR.
  • the hydraulic circuit MI preferably presents, between the use (cylinder CI) and the exhaust tank SC, a check valve VRI, located downstream the motor M and its hydraulic pump, and a valve NS (consisting, in a preferred, but not limited to, embodiment, by a solenoid valve), normally closed in standard operation and placed at the exhaust tank SC of the motor M.
  • a check valve VRI located downstream the motor M and its hydraulic pump
  • a valve NS normally closed in standard operation and placed at the exhaust tank SC of the motor M.
  • the lifting system also includes, preferably, that, when the cylinder CI is completely extended, the door POR is fully open.
  • a micro-switch MIC is applied which, preferably when the cylinder CI is entirely extended, closes (or opens) an electric circuit of consent of the descent control of the door POR, through contacts NA (one placed on the stem of the cylinder CI and one associated with the micro-switch MIC), which normally close themselves when the cylinder CI is wholly open (even if the operation is possible even with reversed contacts, which open when the cylinder CI is opened and close when the cylinder CI is completely closed).
  • the cylinder CI stops even before its stroke end, at the end of the opening of the door POR, thanks to the operation of the micro-switch MIC (or another micro-switch MIC suitably provided), which acts at the stroke end, closing (or opening) the circuit of consent of the descent control of the door POR.
  • the micro-switch MIC or another micro-switch MIC suitably provided
  • the hydraulic lifting circuit MI remains under pressure when the door POR is open, and, in the event that at least one of the pipes TU of the hydraulic circuit MI suffers damages, due for example to collisions, with consequent leakage of hydraulic pressure, the cylinder CI starts retracting, closing the door POR, which falls by gravity, held by the residual pressure within the pipe TU.
  • the micro-switch MIC changes state and this state change generates a block of the closing control of the door POR, thus creating a safety stop, as required by the European standards in force concerning security.
  • the opening stroke of the cylinder CI can be electronically adjusted through the reading of an optometric bar, which may also serve to detect possible leakages of the hydraulic circuit MI, thus denying the consent to the closing control.
  • valve NS During the normal use of lifting the valve NS is constantly closed and it will be opened when they desire to close the door POR for the normal use.
  • VFC a constant flow valve
  • Such a provision allows to keep constant the descent speed of the door POR, even in case of any oil leakage due to the breakage of a pipe TU of the electrohydraulic circuit MI.
  • valve NS in case of absence of the network electricity the use of a simple device of manual opening of the valve NS is also provided, which can be manually handled since the hydraulic gearcase of control of the motor M is located in accessible place; the manual release of the valve NS bypasses the aforesaid block valve NS, and the door POR gets down by gravity, with recover of the oil in the tank SC.
