Description

Technical Field

[0001] This utility model relates to the field of crane equipment, specifically to a crane for intelligent warehousing. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. Steel plates are generally transported using electromagnetic lifting devices to improve work efficiency. In factory workshops, intelligent automated equipment is now widely used for lifting and moving goods. Electromagnetic lifting devices are used for moving steel pipes. However, electromagnetic lifting devices may experience power outages, which can lead to safety hazards. Summary of the Invention

[0003] This utility model provides a crane for intelligent warehousing.

[0004] The technical solution of this utility model is implemented as follows: A smart warehousing crane includes a double main beam, with end beams connected to the ends of the double main beams. A track is provided on the top of the double main beams, and two trolley frames travel on the track. A winch is installed on the trolley frame, and a wire rope is wound on the winch. The lower end of the wire rope passes through a pulley, which is installed on a pulley frame. The pulley frame is installed on a lifting device. The lifting device includes a lifting device beam, and two spaced electromagnetic lifting devices are connected to the lifting device beam. The electromagnetic lifting device includes a lifting device base, with an electromagnet connected to the bottom of the lifting device base. A bearing mechanism is connected to the bottom of the lifting device base. The bearing mechanism includes rotating rods rotatably connected to the four corners of the bottom of the lifting device base. The rotating rods are rotatably connected to the lifting device base through bearings. The rotating rods are hollow structures with a sealed top and an open bottom. A vertically movable bearing frame is provided inside the rotating rods. The bearing frame has an L-shaped structure.

[0005] Two mounting plates are fixedly connected to the top of the spreader beam on both sides. The two ends of the mounting plates extend into the width direction of the spreader beam. Chains are connected to the bottom of the extensions at both ends of the mounting plates. The bottom of the chains is connected to the connecting seats, which are fixedly connected to the four corners of the top of the spreader seat.

[0006] A hydraulic cylinder is installed inside the rotating rod, and the free end of the hydraulic cylinder is fixedly connected to the vertical part of the support frame.

[0007] The rotating rod is externally fixedly connected to a driven gear, which meshes with a driving gear. The driving gear is driven by a drive motor, which is vertically fixedly connected to the lifting device base.

[0008] The pulley frame includes pulley plates with through holes that match the longitudinal section of the lifting beam. The pulley plates are fitted onto the outside of the lifting beam and fixedly connected to it. A connecting shaft connects the two pulley plates, and the pulleys are mounted on the connecting shaft.

[0009] The technical solution of this utility model has the following positive effects: This utility model uses an electromagnetic lifting device to lift steel pipes, and can lift multiple steel pipes simultaneously; a bearing mechanism is set at the bottom of the lifting device base. After the electromagnet attracts the steel pipe, the rotating rod rotates, driving the bearing frame to rotate, so that the horizontal part of the bearing frame rotates to below the steel pipe; a hydraulic cylinder is set inside the rotating rod, and the free end of the hydraulic cylinder is fixedly connected to the vertical part of the bearing frame. The lifting and lowering of the hydraulic cylinder drives the bearing frame to lift and lower, so that the top surface of the horizontal part of the bearing frame contacts the top surface of the steel pipe, which plays a bearing role for the steel pipe and can prevent the steel pipe from falling due to accidental power failure.

[0013] like Figure 1-3 As shown, a smart warehousing crane includes a double main beam 1, with end beams 2 connected to the ends of the double main beams 1. A rail 3 is mounted on the top of the double main beams 1, and two trolley frames 4 travel on the rail 3. A winch 5 is mounted on each trolley frame 4, and a wire rope 6 is wound around the winch 5. A lifting device is connected to the end of the wire rope 6. The lifting device includes a lifting beam 7, on which two spaced-apart electromagnetic lifting devices are connected. Each electromagnetic lifting device includes a lifting base 8, with an electromagnet 9 connected to the bottom of the lifting base 8. A load-bearing mechanism is connected to the bottom of the lifting base 8, and the load-bearing mechanism includes rotating rods 10 rotatably connected to the four corners of the bottom of the lifting base 8. The rotating rods 10 are rotatably connected to the lifting base 8 via bearings. The rotating rods 10 are hollow structures with a sealed top and an open bottom, and a load-bearing mechanism that can move up and down is provided inside the rotating rods 10. The frame 11 has an L-shaped structure. Specifically, the bottom of the lifting base 8 is connected to an electromagnet 9, which can lift multiple steel pipes simultaneously. The winch 5 starts the wire rope 6 to lift and lower, thereby driving the lifting beam 7 to lift and lower. The electromagnet 9 of the electromagnetic lifting device can attract the steel pipes. Multiple steel pipes can be attracted at one time. At the same time, in order to prevent the steel pipes from falling, a bearing mechanism is installed at the bottom of the lifting base 8. The specific working process is that the rotating rod 10 rotates, which drives the bearing frame 11 to rotate, so that the horizontal part of the bearing frame 11 rotates to a position parallel to the lifting beam 7. After the electromagnet 9 attracts the steel pipes, the rotating rod 10 rotates, which drives the bearing frame 11 to rotate, so that the horizontal part of the rotating rod 10 is below the steel pipe. If an accident occurs and the steel pipe falls from the electromagnet 9, the bearing frame 11 will catch the steel pipe.

[0014] Two mounting plates 17 are fixedly connected to the top of the lifting beam 7 on both sides. The two ends of the mounting plates 17 extend in the width direction of the lifting beam 7. The bottom of the extensions at both ends of the mounting plates 17 are connected to chains 18. The bottom of the chains 18 is connected to the connecting seats. The connecting seats are fixedly connected to the four corners of the top of the lifting base 8. Specifically, the lifting beam 7 and the lifting base 8 are connected by chains 18.

[0015] A hydraulic cylinder 19 is installed inside the rotating rod 10. The vertical part of the support frame 11 is located in the cavity of the rotating rod 10. The free end of the hydraulic cylinder 19 is fixedly connected to the vertical part of the support frame 11. Specifically, after the electromagnet 9 attracts the steel pipe, the rotating rod 10 drives the horizontal part of the support frame 11 to the bottom of the steel pipe. Then, the free end of the hydraulic cylinder 19 rises, driving the horizontal part of the support frame 11 to rise, so that the top surface of the horizontal part of the support frame 11 contacts and connects with the bottom surface of the steel pipe.

[0016] A driven gear 12 is fixedly connected to the outside of the rotating rod 10. The driven gear 12 meshes with the driving gear 13. The driving gear 13 is driven by the drive motor 14, which is vertically fixedly connected to the lifting device base 8. Specifically, when the drive motor 14 is started, the driving gear 13 rotates, and the driven gear 12 meshing with the driving gear 13 also rotates. The rotating rod 10, which is fixedly connected to the driven gear 12, rotates, thereby driving the support frame 11 to rotate.

[0017] The pulley frame includes a pulley plate 16 with a through hole that matches the longitudinal section of the lifting beam 7. The pulley plate 16 is fitted onto the outside of the lifting beam 7 and fixedly connected to it. A connecting shaft connects the two pulley plates 16, and the pulley 15 is mounted on the connecting shaft. The pulley plate 16 is fitted onto the outside of the lifting beam to increase the contact area and improve the load-bearing capacity.
