An improved hydraulic lifting sectional security door, capable of being installed at an entry space to a room, comprising a pair of profiles (PRF) near to each frame (STP) of the entry space, a series of panels (PNL) articulated together and a device or group (GP) for lifting the panels (PNL), which includes a hydraulic cylinder (CI), to which fixed and mobile lifting pulleys (PL1, PL2, PL3, PL4) are fixed; according to the invention the lifting cables (FA1, FA2) start from stops (FE1, FE2), which are preferably next to the cylinder (CI) and their exit in the direction of the return pulleys (PU1, PU2) takes place in a balanced manner, on the two outer sides of the lifting pulleys (PL1, PL2, PL3, PL4), so a s to be able to obtain a reversible container (CAS), which allows the hydraulic cylinder (CI) and the exit of the hydraulic tube (TU) to the right or left of the entry space, according to the user's desires and requirements.
摘要:
A door operator system includes a fluid cylinder (10) that has a cylinder body (12) and a rodless piston (30) adapted for reciprocation in the cylinder body (12). A carriage (50) which is adapted for reciprocation externally along the length of the cylinder body (12) is secured to the piston (30). An arm member (70) connects the cylinder carriage (50) to an associated sliding door. A control circuit is provided for controlling the operation of the fluid cylinder (10) and hence the position of the associated sliding door.
摘要:
A driving device for a door with a wing (1) being pivotable around an intermediate horizontal pivot (2) which is so guided as to be vertically slidable along fixed lateral uprights (3), while a pivotable guiding arm (5) is provided on at least one side of the wing, and has one end (6) pivotally connected to the upper part of the respective fixed upright (3), and its opposite end (7) pivotally connected to the door wing (1), at a point that is eccentric to the horizontal pivot (2) around which the wing is pivotable, characterized in that it is placed between at least one of the lateral pivotable guiding arms (5) and the door wing (1 and comprises a hydraulic or pneumatic cylinder (8, 11) and a mechanism (13, 15, 17, 18) which is adapted for converting the rectilinear movement of the cylinder (8, 11) into a relative angular movement over about 180' of the lateral pivotable guiding arm (5) and the door wing (1).
摘要:
Die Erfindung betrifft eine Fixiervorrichtung für ein senkrecht bewegbares Verschließelement (1) zum zumindest teilweisen Verschließen einer Öffnung (2) eines Raumes. Erfindungsgemäß umfasst die Fixiervorrichtung zum Fixieren des Verschließelementes (1) in einem geschlossenen Zustand zumindest eine an dem Verschließelement (1) angeordnete erste Fixiereinheit (6) und eine zu der ersten Fixiereinheit (6) korrespondierende Eingriffseinheit (7) in einem Öffnungsboden (2.1) und zumindest eine zweite Fixiereinheit (11), welche an einer seitlich der Öffnung (2) angeordneten Führung (3) für das Verschließelement (1) angeordnet ist und einen Spannhaken (11.1) aufweist, der im geschlossenen Zustand des Verschließelementes (1) im Bereich einer Oberseite des Verschließelementes (1) in das Verschließelement (1) einrastbar ist.
摘要:
A door assembly including a vertically moving door to permit and prohibit access through an opening which has a top, a bottom defined by a floor, and at least two sides, the door assembly. The assembly having a door body having upper and lower portions, and being mounted proximate the opening such that the lower end portion being proximate the floor when the door is in the closed position. A protective body is configured in connection with the door so as to be moveable between a first position under at least a portion of the door body lower portion when the door is in at least a partially open position and a second storage position. The protective body having at least one debris collecting surface, and opposing ends, the protective body being configured such that debris collected on the debris collecting surface will be urged toward one of the opposed ends.

摘要:
A hydraulic drive system for fire stop gates, comprising an actuator device or group (AT) adapted for the opening of the fire stop gate, while the closing is controlled by means of a compensated deceleration valve (VRC1) which permits closing the gate at a minimum constant speed in case of alarm and/or with the absence of mains power supply, while maintaining all of the standard operating characteristics of the gate, even in the case wherein the same is automatised.
摘要:
The hoist mechanism comprises a hoist axle (10), at least one electric motor (16) for rotating the hoist axle, the electric motor having an axle, and an emergency use system for rotating the said electric motor axle. The emergency use system has been planned to be used when the supply of electric power to the electric motor has been interrupted, for example, because of a power cut or failure in the electrical system. The emergency use system includes a hydraulic motor (22), which is connected to the axle of the electric motor with the clutch (20). When the emergency use system is taken into use, the hydraulic motor is connected to the axle of the electric motor, after which the axle of the electric motor can be rotated by means of the hydraulic motor.
