Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention is described in detail below with reference to the attached drawings.
Example 1
As shown in fig. 1 and 2, this embodiment provides an elevator landing door device, including last bank frame 1, all set up in actuating mechanism, hydraulic press 3 and layer door link plate 4 of body 1, layer door link plate 4 is used for installing the layer door, actuating mechanism is used for the drive layer door link plate 4 round trip movement, hydraulic press 3 is used for pinning when layer door is in the state of closing layer door link plate 4.
In practical use, the embodiment is applied to a side-opening double-folding elevator, namely, the landing door hanging plate 4 is used for installing one landing door, the other landing door hanging plate 6 is used for installing the other landing door, and the landing door hanging plate 6 is installed on the body 1; when the landing door hanging plate works, the driving mechanism drives the landing door hanging plate 4 to move back and forth, so that the two landing doors are relatively close to or far away from each other, and the landing doors are opened and closed; when the landing door is in a closed state, the door lock switch assembly 7 locks the driving mechanism, but at the moment, the external force can still open the door; and in order to avoid the landing door to be opened by external force, the hydraulic press 3 acts at the moment, the landing door hanging plate 4 is locked, namely, the landing door hanging plate 4 cannot move, and therefore the door closing effect is guaranteed.
Because the hydraulic press 3 is used as a locking power source, the self-closing force of the utility model is high, and compared with the prior art, the utility model has a simpler structure; meanwhile, the hydraulic press 3 belongs to a mature technology, so that the hydraulic press has very stable performance, the maintenance period is long, and the maintenance cost is reduced.
In this embodiment, hydraulic press 3 includes hydraulic power spare 31 and rocker subassembly, hydraulic power spare 31 install in body 1, rocker subassembly 5 includes first rocker 32 and control arm second rocker 33, the one end of first rocker 32 rotate set up in hydraulic power spare 31's output, the other end of first rocker 32 with the one end of control arm second rocker 33 rotates and is connected, the other end of control arm second rocker 33 connect in layer door link plate 4. Namely, when the driving mechanism acts, the first rocker 32 and the control arm second rocker 33 are not locked by the action of the hydraulic press 3, so that the first rocker 32 and the control arm second rocker 33 act along with the landing door hanging plate 4; when the door is closed, the hydraulic part acts, and pressure is applied to the second rocker 33 of the control arm through the first rocker 32, so that when the landing door is subjected to opening force, the pressure can prevent the opening force from acting, and the landing door is still in a closed state. Through the cooperation of the driving arm 32 and the control arm second rocker 33, the landing door hanging plate 4 can not be greatly interfered when the landing door hanging plate 4 acts, and therefore the smoothness of the action of the landing door hanging plate 4 is ensured.
In this embodiment, actuating mechanism includes driving piece (not seen in the figure), first drive wheel 22, second drive wheel 23 and wire driving rope 24, first drive wheel 22 with second drive wheel 23 all rotate set up in body 1, the both ends of wire driving rope 24 the first drive wheel 22 with second drive wheel 23 of lap joint respectively, layer door link plate 4 install in wire driving rope 24, the driving piece is used for the drive first drive wheel 22 rotates, hydraulic press 3 warp rocker subassembly 5 is used for forcing first drive wheel 22 second drive wheel 23 stall.
In practice, the driving mechanism is generally a conventional driving member such as a motor, and the second rocker 33 of the control arm is inserted into the first transmission wheel 22 or the second transmission wheel 23 and then mounted on the hitch plate. Taking the example that the second rocker 33 of the control arm is inserted into the second transmission wheel 23, when the landing door moves, the first transmission wheel 22 is driven by the driving mechanism to rotate, so as to drive the steel wire transmission rope 24 to move, so as to realize the driving effect on the landing door hanging plate 4, at this time, because the hydraulic press 3 does not move, the second transmission wheel 23 can smoothly rotate, that is, the second rocker 33 of the control arm cannot block the rotation; after the door is closed, the hydraulic device 3 acts, a locking force is applied to the second rocker 33 of the control arm through the first rocker 32, the second transmission wheel 23 is pressed down through the second rocker 33 of the control arm, the second transmission wheel 23 is prevented from rotating, and the landing door is ensured not to act.
In this embodiment, the body 1 is provided with a plurality of upper sill frame mounting seats 11 for allowing the upper sill frame 1 to be mounted at an elevator doorway of a floor.
Example 2
As shown in fig. 3, the difference between the present embodiment and embodiment 1 is that the present embodiment is a split-type landing door, specifically: the number of the layer door hanging plates 4 is two, and the driving mechanism is used for driving the two layer door hanging plates 4 to move towards the direction close to or away from each other.
That is, the two landing door hanging plates 4 act simultaneously to make the two landing doors close to or far away from each other, thereby realizing the effect of closing and opening the doors. The structure of the driving mechanism is conventional and will not be described herein.
In this embodiment, one of the landing door hanging plates 4 is provided with a rocker assembly seat 41, and the rocker assembly 5 is installed in the rocker assembly seat 41. Namely, when the hydraulic press 3 does not act, the second rocker 33 of the control arm can also move along with the movement of the landing door hanging plate 4, the second rocker 33 of the control arm is rotatably connected with the first rocker 32, and the first rocker 32 is rotatably connected with the hydraulic press 3, so that the interference on the movement of the landing door hanging plate 4 can be avoided; when the hydraulic press 3 acts, the locking effect of the second rocker 33 and the first rocker 32 of the control arm is realized, so that the landing door hanging plate 4 cannot move continuously. The rocker assembly 5 is far away from the rocker arm assembly, which is referred to in the prior art and will not be described in detail herein.
Although the present invention has been described with reference to the above preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
