Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides an electric door rolling machine with a fall-prevention assembly, which includes a door frame 1, a winding drum 2 pivoted on the top of the door frame 1, a first driving mechanism for driving the winding drum 2 to rotate, and a door curtain 4 having one end wound on the winding drum 2 and the other end capable of sliding up and down along a guide rail 3 disposed on both sides of the door frame 1, and further includes two fall-prevention devices 5 respectively disposed on both sides of the door frame 1 and used for preventing the door curtain 4 from sliding down.
As shown in fig. 2, door frame 1 top is equipped with the install bin, and reel 2 pin joint is on the install bin, and first actuating mechanism is located the install bin, first actuating mechanism includes second motor 42, second motor 42 through connecting seat 41 with the roof of install bin is connected, reel 2's pivot with second motor 42 drive is connected, and is concrete, and the pivot of reel 2 passes through chain drive and is connected with second motor 42 drive, and when drive chain took place to break the chain or take off the chain, door curtain 4 can fall fast, and anti-falling device 5 is used for preventing door curtain 4 whereabouts, improves the security.
As shown in fig. 2, the anti-falling device 5 includes a housing 51 disposed on a corresponding side pillar of the door frame 1 and a sliding rod 57 slidably penetrating the housing 51, the guide rail 3 is located in the side pillar, the sliding rod 57 is drivingly connected to a second driving mechanism disposed in the housing 51, and the sliding rod 57 is driven by the second driving mechanism to move so that the sliding rod 57 presses against the side pillar or the door curtain 4 to block the falling of the door curtain 4.
It can be understood that the slide rod 57 is disposed perpendicular to the guide rail 3, the second driving mechanism drives the slide rod 57 to move, and the slide rod 57 blocks the guide rail 3 to block the door curtain 4 when passing through the guide rail 3 and abutting against the side pillar or the slide rod 57 abuts against the door curtain 4 to increase the friction between the door curtain 4 and the guide rail 3 to block the door curtain 4.
As shown in fig. 2, one end of the slide rod 57 close to the guide rail 3 is provided with a blocking plate 58 for blocking the door curtain 4, and when the slide rod 57 is in a blocking state, the blocking plate 58 is engaged with or pressed against the door curtain 4 with the engaging groove 11 provided on the corresponding side upright.
Specifically, when the door curtain 4 is opened and lifted above the sliding rod 57 (i.e., the door curtain 4 is lifted to the top), the second driving mechanism drives the sliding rod 57 to move so that the baffle plate 58 is clamped with the clamping groove 11 on the corresponding side upright column, so as to block the door curtain 4 and prevent the door curtain 4 from falling to hurt people; when the door curtain 4 is not lifted to the top and the lower end of the door curtain 4 is below the slide rod 57, the second driving mechanism drives the slide rod 57 to move, so that the end of the baffle plate 58 is pressed against the door curtain 4, and the door curtain 4 is prevented from falling.
As shown in fig. 3, a plurality of elastic protrusions 581 abutting against the bottom wall of the slot 11 are disposed on the blocking plate 58 at intervals, and the elastic protrusions 581 play a role in buffering and damping, so that the operation process is more stable, and the damage to the surface of the door curtain 4 due to hard contact is avoided, which affects the use.
As shown in fig. 1, the second driving mechanism includes a first motor 52 installed in the housing 51 and a worm wheel 54 pivotally connected in the housing 51, the worm wheel 54 is engaged with a worm 53 connected to an output shaft of the first motor 52, a connecting frame 55 located in the housing 51 is disposed on the sliding rod 57, and a pin 56 eccentrically disposed on the worm wheel 54 is inserted in the connecting frame 55.
When the first motor 52 works, the worm 53 is driven to rotate, the worm 53 rotates to drive the worm wheel 54 to rotate, the pin shaft 56 is driven to move, the pin shaft 56 drives the connecting frame 55 to move, and the connecting frame 55 moves to drive the sliding rod 57 to move, so that the door curtain 4 is blocked or released.
