Abstract

FIELD: construction; mechanical engineering. SUBSTANCE: invention relates to movement systems, and discloses mechanisation of controlling the movement of leaves in a gate opening, in particular to systems for controlling the movement of gate leaves, and can be used for mechanising the control of gates for industrial, warehouse and civil facilities, wherein this system can be used for any openings with suspended sliding leaves. A system for mechanised control of the movement of gate leaves, mounted around the perimeter of the gate opening, contains a drive with a manual control handle, cable lines, a tensioner, suspension rollers, a leaf end position locking unit, limit switches, wherein the cable lines are kinematically connected to the drive and are made in the form of a closed loop encircling the gate opening, with a tensioner mounted in parallel, wherein suspension rollers are mounted along the contour of the cable lines, the leaf end position locking unit is electrically connected to the drive and limit switches mounted in the upper part of the gate opening. EFFECT: simplifying the movement of gate leaves and increasing the reliability of the gate leaf movement drive. 7 cl, 3 dwg

Description

The invention relates to the field of construction and mechanical engineering, namely to movement systems, and discloses the mechanization of control of movement of doors in a gate opening, in particular to systems for controlling movement of gate doors, and can be used to mechanize the control of gates of industrial, warehouse and civil facilities, while this system can be used for any openings with sliding doors, of a suspended type [E06B11/00, E05F15/00, E05F15/60]. A DOOR DRIVE SYSTEM [EP3118405A1, published 18.01.2017] is known from the prior art, comprising a carriage moved along a guide with a built-in electric drive, wherein the carriage is mechanically connected to the door leaf in such a way that when the carriage moves between the first and second end positions, the door leaf moves between the closed and open positions, characterized in that the electric drive is supplied with direct current through power supply means, and at least one functional element is located on the door leaf, the voltage supply to which is carried out through control means built into the carriage. The disadvantage of this door drive system is the dependence of the functional element on the door leaf on the controls built into the moving carriage, which creates a complex connection that is subject to wear and tear and damage due to constant movement, as well as the need to supply power to the moving unit (carriage) for the operation of the entire drive, which increases the number of moving electrical contacts and cables subject to mechanical loads and failures, and, as a result, complicates the movement of the gate leaves and reduces the reliability of the drive for moving the gate leaves. Also known from the prior art are SLIDING GATES [RU39633U1, published 10.08.2004], containing two panels with handles, a ride beam, a gear motor with a drum, a closed rope, characterized in that the connection of the ends of the closed rope is placed on a bracket and secured in the upper part of one of the panels with clamps, and a spring-loaded sprocket is installed inside the drum, placed in a cage and connected through a rod to the handle. The disadvantage of these sliding gates is the use of a closed cable with a connection on the leaf bracket, which creates a stress concentration point and makes it difficult to adjust the length, as well as the use of a spring-loaded sprocket inside the drum, connected to the handle by a complex kinematic mechanism, which increases the number of wearing parts, requires precise assembly and is prone to jamming, especially under conditions of vibration and temperature changes, and, as a result, complicates the movement of the gate leaves and reduces the reliability of the drive for moving the gate leaves. The closest in technical essence is the Intelligent Control of Steel Gates [CN112900377A, publ. 04.06.2021], is characterized in that the system includes a multi-point housing consisting of a lower threshold with columns fixed at both ends, on which a door lintel is installed, while the door leaf is slidingly located on the columns, and to achieve sealing, a lower water stop rubber is installed on the lower threshold, interacting with the door leaf, while a side water stop with a pressure plate is fixed on the column and also interacts with the leaf for lateral sealing, a wedge-shaped pressure block is provided between the column and the leaf, a guide post is fixed in the upper part of the leaf, and the leaf itself has several lifting points, each of which is tensioned by a steel cable connected to a tension adjustment device installed in the lower part of the guide post, while the connection of the guide post with the door lintel is provided with an extreme wear-resistant bushing, and a gearbox is installed on the lintel, above which a manual device is sequentially located opening and closing, a gear motor and an encoder, wherein the manual device is connected to the gear reducer and the gear motor, and the gear reducer is connected through the main spindle to the lifting wheel, on which a steel cable is wound, in addition, the door lintel is equipped with a safety switch, upper and lower limit switches, as well as a distributed clamp for wires and internal protective covers for the passage of wires at both ends. The main technical problem of the prototype is the complex and cumbersome kinematic scheme with many disparate elements (the main spindle, the lifting wheel, several separate lifting points with individual cables and tension adjustment devices), which creates difficulties in synchronization and increased wear, as well as the placement of critical drive components (gearbox, gearmotor) at a height on the door lintel, which complicates their maintenance and repair, increases the load on the structure and requires the use of additional safety elements that increase the complexity of the system and, as a result, complicates the movement of the gate leaves and reduces the reliability of the drive
