Description

Technical Field

[0001] The invention belongs to the technical field of cable reel storage, and in particular relates to a cable reel storage device and a control method. Background Art

[0002] At present, power cables are generally wrapped on power cable reels for packaging, transportation and storage. When storing cables in traditional ways, since the common I-shaped cable reels cannot be stacked, only one layer of cable reels can be stored on the ground, which takes up a large storage area. When storing cables in three dimensions, the support structure of the cable reels on the lower layer is fixedly installed on the lower layer, and there is a shielding from the upper support structure. The crane hook cannot directly lift and place the cable reels on the lower layer, which makes it inconvenient to store and use the cable reels.

[0003] The Chinese utility model with publication number CN203921778U discloses a multi-layer cable shelf that can hold various types of cables. The first cable drum, the second cable drum, and the third cable drum are respectively installed between the lower shelf pillars. The first cable drum, the second cable drum, and the third cable drum are connected by a transmission shaft. The right end of the transmission shaft is connected to a drive motor. A first clutch is arranged between the first cable drum and the second cable drum, and a second clutch is arranged between the second cable drum and the third cable drum. Wire blocking plates are arranged on both sides of the first cable drum, the second cable drum, and the third cable drum. The cable hanging rack has three layers, and a cable placement plate is arranged above each layer of the cable hanging rack. A cable hanging hook is installed at the end of each cable hanging rack. The device places cables by setting up multi-layer shelves, but the cable drum on the device is arranged at the lower layer, and the hook cannot retrieve the cables.

[0004] The Chinese invention with publication number CN104044855A provides a cable tray shelf for electric power, which has a cylindrical shell, at the center of which is provided an elevator and an elevator track for the elevator to move in the vertical direction; the space between the elevator track and the shell is divided into several layered storage spaces by two circular ring planes; each layer of the circular ring plane is composed of two inner and outer concentric circular ring surfaces. However, the shelf is arranged in an overall ring shape, with low space utilization and high storage cost, because the upper cable tray is transported to the first conveyor belt in the center by the elevator and the conveyor belt, and then picked up and placed by a forklift. In addition, the lifting track is used, and the cable tray is heavy and requires high energy consumption. Summary of the invention

[0005] The object of the present invention is to provide a cable reel storage device and control method, which utilizes a track to perform horizontal reciprocating motion to achieve the advancement and push-out of the lower cable reel, thereby facilitating lifting operations and solving the problem that when existing cable reels are stored in a three-dimensional manner, the cable reel located at the lower layer is not convenient for direct lifting and placement.

[0024] The above scheme is a cable reel storage device, which stores the lower cable reel 6 by setting up a reciprocating cargo tray mechanism, and transports the reciprocating cargo tray mechanism from the lower layer through the driving mechanism 76, so as to facilitate the lifting of the lower circuit board by the overhead crane, thereby solving the problem of inconvenience in lifting the lower cable reel 6 in the existing three-dimensional storage, realizing the stacking function of the cable reel 6, effectively utilizing the height space of the storage to store the cable reels 6 in sequence, and facilitating reuse, thereby improving production efficiency, and at the same time effectively solving the need for large-area storage of cable reels 6, reducing the storage cost of the enterprise, and helping to realize standardized warehouse operations.

The rollers 75 correspond to the tracks 72, and the rollers 75 are arranged on the corresponding tracks 72.

[0028] As a preferred example of the above embodiment, the end of the track 72 is bent upward to form a bent portion, which can buffer the reciprocating cargo tray mechanism 7 after it is transported out, avoiding collision caused by excessive braking that affects the quality of the cable tray.

The cable tray 6 on the second layer is stored in an open state, and the overhead crane directly takes and places the cable tray 6 on the fixed cargo tray mechanism 5. The cable tray 6 on the lower layer cannot be directly lifted and placed because it is wrapped by the shelf 1 and blocked by the upper cable tray 6. The loading plate 73 of the horizontally moving reciprocating cargo tray mechanism 7 slides on the track 72 to push one layer of cables out of the shelf 1 for lifting operation. After lifting, the loading plate 73 is driven to slide on the track 72 by the reciprocating cargo tray mechanism 7 to return the loading plate 73 to the inside of the shelf 1.

[0036] As a preferred example of the above embodiment, the slope of the bearing portion is composed of a plurality of rollers arranged obliquely, and rolling friction is formed between the rollers and the outer side of the cable drum to avoid friction and wear on the contact position of the cable drum when the cable drum is taken or placed.

At this time, the elastic member is in a compressed state and has a force to push the two bearing plates inward. At this time, the two bearing plates are stably placed on the cable drum and can adapt to cable drums of different sizes, with a wider range of applications.

[0038] Optionally, in one embodiment, a PLC controller for controlling the drive mechanism 76 and the external crane is fixedly installed on the shelf 1.

[0040] Specifically, the PLC controller controls the forward and reverse rotation and speed of the motor 761. When the motor 761 rotates, its output shaft drives the worm gear 762 to rotate, and the rotation of the worm gear 762 drives the worm 763 to rotate, thereby driving the rotating shaft 74 to rotate. The roller 75 on the rotating shaft 74 rolls in the corresponding direction and at the corresponding speed, thereby driving the entire compound motion cargo tray mechanism to move, thereby realizing the transportation of the cable tray 6.

[0041] Optionally, in one embodiment, a top tray rack is added to the upper tray rack 2 to store the cable trays, and the track of the upper tray rack 2 extends from one side, and the track of the lower tray rack 3 extends from the other side, thereby adding more storage space without affecting the use of the overhead crane.
