DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0020] A PLC control device for a six-section and twelve-story elevator, including a PLC controller body 1. A upper wiring row 2 is fixedly connected to the upper front position of the PLC controller body 1. A limiting vertical plate 3 fixedly connected to the PLC controller body 1 is provided directly above the upper wiring row 2. Combined square frames 5 are integrally formed on the left and right sides of the limiting vertical plate 3 respectively. A support rod 6 is slidably connected to the top position of the combined square frame 5. The protruding ends at the rear ends of the two support rods 6 are connected by a movable pressure roller 7. A fixed pressure roller 9 is fixedly connected to the lower rear position of the limiting vertical plate 3. The bottom end of the support rod 6 is fixedly connected to a slider 12 arranged inside the combined square frame 5. A locking block 10 is fixedly connected to the front end of the slider 12. A spring 11 is fixedly connected to the bottom of the slider 12.

[0021] As Figure 1 shown, a lower wiring row 13 is provided at the lower front position of the PLC controller body 1. Display lights 14 are respectively provided at the upper middle and lower middle positions of the front end of the lower wiring row 13. There are 2 rows of display lights 14 in total. After the control wiring is firmly connected to the upper wiring row 2 or the lower wiring row 13, the display lights 14 will emit light, playing a role in prompting that the wiring is in place; a guide opening 4 is opened at the top position of the limiting vertical plate 3. A plurality of guide openings 4 are arranged in an equidistant structure along the horizontal direction. The outer shape of the guide opening 4 is a semi-circular structure. When bending and leaving the control wiring, the setting of the guide opening 4 can play a role in limiting the control wiring and preventing adjacent groups of control wiring from crossing and winding.

[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a notch 8 is provided on the front end face of the movable pressure roller 7. The outer shape of the notch 8 is arranged in a long strip structure with a concave and hollow shape. The setting of the notch 8 mainly serves to assist in traction and stretching to adjust the movable pressure roller 7. The fixed pressure roller 9 and the movable pressure roller 7 are arranged opposite to each other in the up and down positions. The spring 11 is fixedly installed inside the combined square frame 5. A chute slidably connected to the lock block 10 is provided at the front end of the combined square frame 5. The outer shape of the lock block 10 is a "T" - shaped structure. When the support rod 6 realizes stretching adjustment along with the movable pressure roller 7, the sliding fit between the lock block 10 and the combined square frame 5 will play a certain role in sliding - guiding and limiting.

[0023] Working process: All the electric energy required when the device in the present utility model starts and runs comes from the elevator main control power module. Before using this PLC control device, first, it is fixed to the elevator main control cabinet in the way of being installed along the guide rail as a whole, and the movable pressure roller 7 is pre - adjusted to stretch upward. The operator can, according to the wiring requirements, first pull multiple pre - marked control wires from the back to the front through the space between the movable pressure roller 7 and the fixed pressure roller 9, and make them able to be stuck into the corresponding guide openings 4 and extend to the front end position of the limiting vertical plate 3. Then, in the way of screwing and fastening with bolts, after connecting multiple pre - marked control wires to the upper wiring row 2 in sequence, after removing the traction force on the movable pressure roller 7, the movable pressure roller 7 will realize downward reset and rebound through the support rod 6 and the slider 12 by means of the rebound force generated after the deformation of the spring 11. At the same time, the whole PLC control device will, through the clamping cooperation between the movable pressure roller 7 and the fixed pressure roller 9, bend and leave wires for multiple control wires at the same time, and this clamping structure can also play a role in clamping and limiting the control wires to prevent the problem of the control wires being pulled outwards. Finally, after ensuring that multiple control wires are firmly connected to the whole PLC control device, the PLC control device will start and carry out intelligent and automatic control on the six - part twelve - floor elevator according to the pre - input program commands.

[0024] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
