Description

Technical Field

[0001] The utility model relates to the technical field related to shuttle logistics overhead cranes, in particular to a shuttle logistics overhead crane. Background Art

[0002] Shuttle logistics overhead crane, also known as logistics overhead crane, can shuttle between raw material warehouse, processing area, finished product or semi-finished product warehouse, and even between different floors. The overhead crane runs on an aerial track and performs point-to-point material placement and transportation. The device is set at a high place, which can save bottom space, reduce manpower and material costs, and also reduce the pollution generated by the work.

[0003] During use, existing logistics overhead cranes place items in a compartment with a certain depth. When items are placed in a compartment with a certain depth, the height of the items is lower than the depth of the compartment, and the items will not run out of the compartment, which can improve the safety of material transportation. However, due to the deepness of the compartment, it is more difficult for workers with limited arm length to reach the items at the bottom of the compartment when retrieving items. Reaching into a deeper compartment and grabbing items requires greater muscle strength and joint mobility. When the compartment is too deep, people may need to reach for items in an unnatural posture, which is not only laborious but may also put pressure on the joints. A deeper compartment may obstruct the line of sight, making it difficult for people to see the items at the bottom of the trough, thereby increasing the difficulty and time of retrieving items. In summary, the existing shuttle logistics overhead cranes are relatively inconvenient when retrieving items. For this reason, we propose a shuttle logistics overhead crane. Utility Model Content

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Example: Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the present invention discloses a shuttle logistics overhead crane comprising a linear frame 1 with multiple mounting holes at each end. A chute 2 is defined on each side of the linear frame 1. A movable seat 3 is disposed at the lower end of the linear frame 1, and the upper end of the movable seat 3 extends through the linear frame 1. Multiple equally spaced rollers 21 are rotatably mounted on either side of the movable seat 3, and the rollers 21 are positioned within the chute 2 on the same side. The linear frame 1 is mounted high in a factory or workshop using screws. A traction mechanism is provided at each end of the linear frame 1, connected to the movable seat 3 and capable of moving the movable seat 3 along the chute 2. The traction mechanism comprises two spaced support plates 15, which are fixedly attached to the linear frame 1. A reel 16 is rotatably mounted between the two support plates 15. A connecting rope 18 is fixedly connected to and retracted within the reel 16. One end of the connecting rope 18 is fixedly attached to the movable seat 3. A second motor 17 is fixedly mounted on the support plates 15, and the output shaft of the second motor 17 is fixedly connected to the reel 16. One of the second motors 17 on either side is activated. When an item needs to be moved to a certain side, the second motor 17 on that side is activated, which drives the reel 16 to rotate. The reel 16 on one side reels in the connecting rope 18, while the reel 16 on the other side releases the connecting rope 18, pulling the movable seat 3 to move to one side and the roller 21 rolling in the chute 2. Thus, the traction mechanism drives the movable seat 3 and the storage tank 4 below to move horizontally and transport the goods.

[0024] When the storage slot 4 moves, the roller 21 rolls in the slide 2, and the second motor 17 mainly overcomes the rolling friction between the roller 21 and the slide 2. Compared with the traction method of overcoming sliding friction in the prior art, the traction method of this application is more labor-saving and reduces power consumption.

[0025] The movable seat 3 has a storage tank 4 at its lower end, with notches 5 on either side. Hydraulic rods 6 are fixedly mounted at each corner of the bottom of the movable seat 3. The output ends of the hydraulic rods 6 are fixedly connected to the top of the storage tank 4. A movable plate 7 is mounted on each side of the storage tank 4. Each side of the storage tank 4 is equipped with an adjustment mechanism, which is connected to the movable plate 7 on the same side and can drive the movable plate 7 in the vertical direction. The adjustment mechanism includes two connecting blocks 8 fixedly connected to each side of the movable plate 7. The connecting blocks 8 are located at the upper end of the movable plate 7. The lower ends of the connecting blocks 8 are each provided with a block 9 fixed to the storage tank 4. The blocks 9 are penetrated by a guide rod 10, the upper end of which is fixedly connected to the bottom of the connecting block 8. The adjustment mechanism also includes a friction bar 11, which is embedded in the movable plate 7 and integrally connected. A support frame 12 is fixedly mounted at the bottom of the storage tank 4. A first motor 13 is fixedly mounted on the support frame 12. A friction wheel 14 is fixedly mounted on the output shaft of the first motor 13. The friction wheel 14 contacts the friction bar 11, and the two can transmit power through friction.

[0026] By placing multiple items in the storage slot 4, the first motor 13 drives the friction wheel 14 to rotate, and the friction wheel 14 drives the friction bar 11 to move, which can drive the movable plate 7 to move upward, so that the movable plates 7 on both sides move upward and are in a high position. The first motor 13 remains in a self-locking state, and the movable plates 7 on both sides can block the notches 5 on both sides, preventing the items in the storage slot 4 from falling out during transportation. At the same time, according to the height of the items in the storage slot 4, the first motor 13 drives the upper end of the movable plate 7 to move to an appropriate height to limit the position of the items on both sides, which makes the movable plate 7 more widely applicable.

[0027] When the goods are transported to one end of the bar rack 1, the first motor 13 at this end starts to work and drives the friction wheel 14 to rotate in the opposite direction. The friction wheel 14 drives the friction strip 11 downward and drives the movable plate 7 downward along the guide rod 10. The notch 5 at this end is in an open state, making it easier for workers to remove the goods from the storage tank 4. The retrieval process saves time and effort and improves efficiency. At the same time, when loading and unloading goods, the storage tank 4 can be driven up and down by the hydraulic rods 6 around it. By adjusting the height of the storage tank 4 to a suitable height, it is convenient for workers to load and unload goods.

[0028] Among them, the bottom surface of the storage slot 4 is provided with anti-skid lines, so that items placed in the storage slot 4 are not easy to slip, making the storage slot 4 more stable during movement.

[0029] Two spaced-apart stoppers 19 are fixedly mounted on both ends of the inner side of the strip frame 1. The stoppers 19 are fixedly connected to the inner side of the strip frame 1, and a buffer pad 20 is fixedly connected to the side of the stoppers 19 facing the movable seat 3. When the second motor 17 drives the movable seat 3 toward the strip frame 1, and when the movable seat 3 moves to the farthest point at one end of the strip frame 1, the speed of the second motor 17 decreases, and the movable seat 3 comes into contact with the buffer pad 20. The buffer pad 20 cushions the movable seat 3, reducing the impact force of the movable seat 3 on the strip frame 1, thereby protecting the device and making the stop of the movable seat 3 more gentle and smooth, preventing the goods in the storage tank 4 from sliding due to inertia caused by the sudden stop of the movable seat 3, thereby improving the safety of the device operation.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
