The present invention will be described in further detail with reference to the accompanying drawings, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed embodiment and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1a, 1b and fig. 2a, the utility model provides a gate channel switch vertical type vertical hinged door device, its vertical type vertical hinged door device is by door 1 and fan door axle subassembly, the spacing subassembly 2 of door corner, door automatic re-setting mechanism 3, door switch and force control mechanism 4 that opens the door, module bottom plate 5.
As shown in fig. 3a and 3b, the door leaf and door leaf shaft assembly of the vertical side-hung door device; the structure of the door comprises a door leaf 11, a door leaf bearing and bearing seat 12 and a door leaf shaft connecting piece 13. The PC door leaf 11, because the PC material transmittance is good, the inboard lamp strip that pastes of axle can the door leaf send different colours. The door bearing and the bearing shaft seat on the bearing seat 12 can fix the module to be connected with the gate machine, and the bearing can ensure that the door and the gate machine are in rolling connection and can freely rotate without resistance, so that an opening and closing assembly of a gate machine channel is formed. The door leaf shaft connecting piece 13 is connected with the brake shaft 24.
As shown in fig. 4a and 4b, a door corner limiting component of a vertical side-hung door device; the structure of the brake is composed of a corner limiting base 21, a rotating limiting block 22, a fixed limiting bolt 23 and a brake shaft 24, and the combination and the composition of the parts.

Two ends of the self-resetting torsion spring 32 are respectively fixed on the self-resetting torsion spring cover 31, and the other end is fixed on the torsion spring locking driven member 33. The self-resetting torsion spring cover 31 can also adjust the torsion of the self-resetting torsion spring 32-as required, and the self-resetting torsion spring cover 31 is fixed at the lower end of the corner limiting base 21. The torsion spring locking driven part 33 is connected with the brake pad of the resetting electromagnetic brake 34, so that the end of the self-resetting torsion spring 32, the torsion spring locking driven part 33 on the end and the brake pad of the resetting electromagnetic brake 34 form a rotatable movable body. The lower portion of the reset electromagnetic brake 34 is connected to a reset electromagnetic brake bottom plate 35. The rotating power of the movable body comes from the brake shaft 24, that is, the rotating force of the brake shaft 24 is transmitted to the torsion spring locking driven member 33 through the torsion spring locking driving member 36, and the movable body is rotated, so that one end of the self-resetting torsion spring 32 is rotated to generate a certain spring torsion. When the door is rotated to the door closing position of the gate passage, the reset electromagnetic brake 34 is electrified, the magnetic force of the static brake pad attracts the dynamic brake pad of the upper brake, and at the moment, the large torsion of the self-reset torsion spring 32 is locked. When the brake is in power-off state, the reset electromagnetic brake 34 is powered off, the dynamic brake sheet is separated from the static brake sheet, one end of the movable body is released, but the self-reset torsion spring 32 at the other end generates a rotating force due to the existence of large spring torsion, the rotating force is transmitted to the torsion spring locking driving piece 33 through the torsion spring locking driven piece 36 on the movable body, the brake shaft 24 is rotated, the rotating force of the brake shaft 24 is transmitted to the door leaf shaft, at this time, the door leaf is rotated and restored to the initial door opening position by the torsion of the self-reset torsion spring 32 no matter the door leaf is in the door closing position of the brake passage or in any other position, and the mechanism realizes the automatic opening and resetting function of the power-off door leaf of the brake.
The other function of the automatic reset mechanism of the door leaf is a non-following function, the engaging concave teeth of the connecting part of the torsion spring locking driving part 33 and the torsion spring locking driven part 36 are designed into a groove with a large enough size, when the door leaf is at a closed position, the reset electromagnetic brake 34 is electrified and attracted, the torsion spring locking driven part 33 is fixed by magnetic force, as the groove space designed by the torsion spring locking driven part 33 meets the opening angle of the door leaf, the engaging convex teeth of the torsion spring locking driving part 36 can only rotate in the space of the groove of the torsion spring locking driven part 33, the torsion spring locking driven part 36 does not follow the torsion spring locking driving part 33, namely the self-resetting torsion spring 32, under the condition, torsion force cannot be generated on the vertical hinged door mechanism, and therefore, when the vertical hinged door mechanism normally opens and closes the door, the torsion spring does not participate in movement, the control is easy and accurate, and the power loss of the servo motor is small.

The reducer output shaft 41 is connected to the brake shaft 24. The speed reducer 42 is used for reducing and increasing force, so that the braking force of the brake electromagnetic brake 45 and the driving force of the servo motor 47 are increased according to the speed ratio, and meanwhile, the opening and closing speed of the door is reduced to meet the requirement. The brake electromagnetic brake 45 is used for generating braking force to limit the rotation of the transmission mechanism, so that the door can not be easily pushed open, and the magnitude of the braking force is equal to that of thrust of more than 250N generated on the door. The servo motor 47 is used for driving the door leaf to open and close through the transmission mechanism and generating a feedback signal when the door leaf meets external force so as to realize the human clamping prevention function and the blocking function of forced opening of the side-hung door device. The servo controller line interface 48 is connected to the signal line and the power line interface assembly 49 is connected to the power supply.

When the controller generates a signal to drive the servo motor 47 in a door opening state of a perfect side hung door device, the rotational force of the motor is transmitted to the brake shaft 24 through the decelerator 42. The braking shaft 24 will generate a vertical shaft output rotation force for connecting the automatic door leaf resetting mechanism 3, and a vertical shaft output rotation force for driving the door leaf and the door leaf shaft assembly 1. The vertical shaft outputs a rotating force to drive the door leaf, the door leaf shaft 1 and the rotation limiting block 22 to rotate together, when the rotation limiting block 22 rotates and touches the fixed limiting bolt 23, the servo motor 47 is blocked to stop rotating and sends a signal to the servo controller, namely, the door leaf is determined to move to a first limit position, then the servo controller drives the servo motor 47 to rotate reversely, when the rotation limiting block 22 rotates and touches another fixed limiting bolt 23, the servo motor 47 is blocked to stop rotating again and sends a signal to the servo controller, namely, the door leaf is determined to move to a second limit position. Therefore, the servo motor 47 drives the door to rotate to find two limit points, namely, the maximum angle at which the door can rotate, the servo controller can position the midpoint of the angle as the door closing position, namely, the position of the door perpendicular to the gate passage, and the starting position of the door, namely, the opening position of the door, is set according to the passing direction of pedestrians in the gate passage, and then the servo motor 47 drives the door to rotate in the 90-degree angle according to signals, namely, the normal gate opening and closing movement is realized.

open and stop (open and close) function: after a vertical side hung door device of a gate channel switch is electrified and started, firstly, a control system is subjected to self-checking and initialization, then, torque output by a servo motor 47 is transmitted to a door leaf and a door leaf shaft assembly 1 through a speed reducer 42 and a brake shaft 24, the door leaf shaft drives the door leaf to rotate and simultaneously drives a rotation limiting block 22 to rotate, the rotating limiting block 22 can find two fixed limiting bolts 23, the door leaf rotates in a rotation angle which is slightly larger than 180 degrees and is formed by the two fixed limiting bolts 23, the stop point of the fixed limiting bolt 23 which is found by the servo motor 47 in a rotating mode is the starting point of the door leaf opening position, after the door leaf opening angle is found, a servo controller can determine the fixed limiting bolt 23 at one end as the starting point of the door leaf according to the preset pedestrian entering direction, determine the middle point of a corner formed by the two fixed limiting bolts 23 as the end point of the door leaf opening, i.e. the closed position of the door of the gate. The normal work is that the door leaves take the fixed limit bolts 23 as the starting point and the middle point of the corner formed by the two fixed limit bolts 23 as the end point according to the opening and closing instruction, and the door of the gate channel is closed. Or the middle point of a corner formed by the fixed limit bolt 23 is taken as an initial point, and the fixed limit bolt 23 is taken as an initial point to perform the door opening movement of the gate passage. Therefore, the reciprocating operation forms the door opening and closing function of the vertical side hung door device.

When the resistance disappears, the vertical side-hung door device can restore the closing work of the leaf door.

In order to avoid damaging pedestrians passing through the gate, only when the forced door opening thrust acting on the door leaf is more than 250N, the door leaf of the gate can be forcibly pushed open, and the control is the forced door opening function of the door leaf of the vertical hinged door device. When the forced door opening thrust force disappears, the vertical hinged door device restores to a door leaf closing state.
The automatic reset function of the door leaf: when the vertical sliding door device works normally, when no pedestrian passes through the gate, the door leaf is in an extended door closing state, and the automatic reset mechanism 3 of the door leaf is electrified for the first time, under the drive of the output shaft of the brake shaft 24, the 32 self-reset torsion spring is screwed to the limit point of closing the door leaf, the reset brake 34 is electrified to be attracted by the dynamic and static brake sheets, the self-reset torsion spring 32 on the dynamic brake sheet is locked by the mechanism, at the moment, the torsion of the self-reset torsion spring 32 is enough to push the door leaf to move, so that the self-reset torsion spring 32 does not participate in the movement when the vertical sliding door device normally opens and closes the door, when in an emergency situation of power loss, the servo motor 47 driving the door leaf loses power, the reset brake 34 also loses power, the static brake sheet is separated, the dynamic brake sheet of the reset brake sheet 34 is not restrained, the vertical sliding door device rotates under the torsion action of the self-reset torsion spring 32, and the automatic reset mechanism 3 generates the torque, the door leaf assembly is transmitted to the door leaf assembly 1 through the corner reversing mechanism 2, so that a gate channel is opened rapidly, and personnel can pass through the gate safely and smoothly, and the function is the automatic reset function of the door leaf.
