Description

Technical Field

[0001] The utility model relates to the technical field of upper and lower layer conveying equipment, in particular to a movable pulley type cylinder lifting device. Background Art

[0002] With the rapid development of the logistics industry, the traditional single-layer conveyor system can no longer meet the growing transportation needs. This system usually places the goods on a single-layer conveyor, transports them to the designated workstation, and then returns the empty pallet along the original route. However, this transportation method has obvious efficiency bottlenecks.

[0003] In actual operation, a single-layer conveyor can only deliver one batch of goods to a designated workstation at a time, and then it must wait for the empty pallet to return before delivering the next batch of goods. This means that half of the time is wasted on the return of the empty pallet during the conveying process. This traditional conveying method reduces the overall conveying efficiency by about 50%.

[0004] Therefore, it is extremely urgent to develop a movable pulley type cylinder lifting device for upper and lower layer docking. Utility Model Content

[0005] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a movable pulley cylinder lifting device, which can be connected with the corresponding equipment between the upper and lower layers, so that the upper module can be put into storage and the empty pallet can be returned to the lower layer to continue to connect with the new module, thereby greatly improving the production efficiency and solving the problem that the current single-layer conveying equipment has low working efficiency and is difficult to meet the new energy industry's demand for high production efficiency.

[0006] The technical scheme adopted by the utility model is as follows: a movable pulley type cylinder lifting device comprises a main frame, and a first guide rail and a second guide rail are respectively arranged on the columns of the main frame in the vertical direction, a movable frame is matched on the first guide rail, and a lifting slide is matched on the second guide rail; sprockets are assembled on both sides of the movable frame, and a chain is mounted on the sprocket, one end of the chain is fixedly connected to the top of the screw rod after passing through the sprocket, and the screw is fixed on the main frame, and the other end of the chain is fixedly connected to the side wall of the lifting slide through the sprocket and a connecting piece; a power unit is arranged along the vertical direction below the movable frame, and the output end of the power unit is against the bottom surface of the movable frame, and the power unit drives the movable frame to slide and cooperate along the length direction of the first guide rail, and the sprockets on both sides of the movable frame move up and rotate to drive the lifting slide at the other end of the chain to slide and cooperate along the length direction of the second guide rail.

[0007] As a further improvement of the above technical solution:

[0008] Preferably, a stopper is provided on the top of the main frame, and the stopper is arranged directly above the movable frame in the vertical direction. When the movable frame rises to its position, the stopper on the top of the movable frame abuts against the stopper.

[0009] Preferably, a down-to-place stopper is provided at the bottom of the main frame, and the down-to-place stopper is arranged directly below the lifting slide in the vertical direction, and the bottom of the lifting slide abuts against the down-to-place stopper when the lifting slide descends to its position.

[0010] Preferably, a horizontal conveyor is provided on the lifting slide; the structure of the horizontal conveyor is: comprising a plurality of roller structures arranged along the horizontal direction.

[0011] Preferably, a limiting member for docking is arranged above the horizontal conveyor.

[0012] Preferably, the multiple rollers are connected by synchronous belts.

[0013] Preferably, a horizontal in-position photoelectric sensor is also provided on one side of the horizontal conveyor, and the horizontal in-position photoelectric sensor is directly opposite to the conveying station of the horizontal conveyor.

[0014] Preferably, the horizontally positioned photoelectric device is assembled on a guide bar arranged in the horizontal direction through a photoelectric mounting seat, and the photoelectric mounting seat and the guide bar are horizontally slidably matched. When the photoelectric mounting seat moves, the horizontally positioned photoelectric device is driven to adjust its position in the horizontal direction.

[0015] Preferably, the power unit is configured as a cylinder structure.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model has a compact structure and is easy to operate. The movable frame is lifted by the power unit, and the movable frame drives the sprockets on both sides to be lifted synchronously when it rises along the first guide rail. When the sprocket is lifted, an upward force is applied to the chain so that the lifting slide connected to the bottom side of the chain rises vertically along the corresponding second guide rail. Compared with the traditional motor-driven elevator, the utility model can reduce the total height of the equipment and improve the space utilization rate under the same lifting height.

[0018] The utility model also has the following advantages:
