Description

Technical Field

[0001] The present invention relates to the technical field of transport devices, in particular to a transport device based on safety ergonomics. Background Art

[0002] Currently, in the fields of warehousing and logistics, handling devices are widely used. Among them, manual carts are one of the most frequently used devices. They play a role in the internal transportation of goods in the entire process. However, existing manual carts still have some problems, as follows:

[0003] On the one hand, the existing manual carts rely too much on manual operation and pushing. The goods need to be manually moved onto the cart, which not only leads to low efficiency of the entire transportation process, but also makes the transporters very tired, further reducing the efficiency of use. On the other hand, the safety of the manual carts is not enough. It is inevitable to encounter ups and downslopes during transportation. The existing manual carts’ measure to deal with ups and downslopes is to simply tie and fix the goods on it. However, this method will cause the center of gravity of the goods and the cart to shift on the slope. Especially when the center of gravity of heavier goods shifts, it is very easy to cause the entire cart to overturn, resulting in very low use effect of the entire cart and insufficient safety. For this reason, we propose a transport device based on safety ergonomics. Summary of the Invention

In this way, the weight of the goods can always form an effective downward force, ensuring the stability of the handling device, and greatly improving the efficiency and effect of handling.

The conveying component 4 is snapped into the suspension buckle 36 and is movably set. The limiting card slot 37 is opened in the middle of the bottom end of the arc-shaped protruding structure at the bottom of the frame 31. In this way, the first motor 34 is used to drive the rotating wheel 32 to rotate, which can It drives the internal stacking support component 5 to rotate, so that the goods transported into the frame 31 can be supported and stacked layer by layer, which greatly reduces the manpower input and ensures the continuous and efficient work efficiency of the workers.

The other end of the bottom plate 122 is located inside the outer base 121 and an extension rod 128 is movably installed.

[0041] In this embodiment, it should be noted that the two ends of the top of the outer base 121 are fixedly connected to the lower surface of the base platform 1, the length of the supporting groove 124 is greater than or equal to the sum of the lengths of the supporting bottom block 125 and the supporting top block 127, the ends adjacent to the supporting bottom block 125 and the supporting top block 127 are both provided with an inclined surface structure, and the top end of the supporting bottom block 125 and the bottom end of the supporting top block 127 are both provided with a supporting cross surface, the limiting card plate 126 is movably arranged above the bottom plate 122, and its top end is provided with an arc surface adapted to the arc-shaped protruding structure at the bottom end of the frame 31 and a limiting tooth is provided on the arc surface, the limiting tooth can be engaged with the limiting slot 37, and the extension rod 128 is provided to contact the end of the automatic trigger component 13, The two sides of the extension rod 128 are fixedly connected to the connecting rod 64, so that the automatic trigger component 13 is used to trigger the movement of the internal structure on the slope to drive the extension rod 128 to push the base plate 122 to move, and then the limit card plate 126 originally attached to the upper surface of the base plate 122 is lowered under the action of the inclined surface structure set between the supporting bottom block 125 and the supporting top block 127. In this way, the limit teeth on the limit card plate 126 will release the limit on the limit slot 37, so that the outer frame component 3 as a whole can be suspended around the position of the top suspension ring buckle 36 when it is subsequently moved to the inclined surface and remain in a vertical state, avoiding the movement of the center of gravity of the transport device on the inclined surface and causing overturning, thereby greatly improving the stability of the use of the transport device.

[0042] See also Figure 2-8 A handling device based on safety and ergonomics includes an automatic trigger assembly 13. The automatic trigger assembly 13 includes an outer shell 131.

The specifications of the two inner airbags 133 are completely consistent.

When the slope of the encountered inclined surface makes the horizontal component of the inner slider 132 reach the set threshold, it can push the bottom plate 122 to move so that the supporting top block 127 at the bottom end of the limiting card plate 126 falls into the supporting groove 124, and then the limiting tooth at the top end of the limiting card plate 126 will separate from the limiting card groove 37, thereby releasing the restriction on it. In this way, the outer frame assembly 3 and the cargo inside it that are subsequently moved to the inclined surface can be transported in a suspended manner to avoid overturning.

[0044] Working principle: unfold the conveying components 4 on both sides so that the two end frames 43 touch the ground or table, start the second motor 45, and the second motor 45 drives the conveyor belt 46 to rotate through the inner wheel, and the goods are placed on the conveyor belt 46 for transportation. At the same time, start the first motor 34 to rotate intermittently, thereby driving the threaded rod 51 to rotate intermittently to pull the carrier sheet 53 upward intermittently, and the goods are inserted between the intermittently moving carrier sheets 53 for palletizing. Until all the goods are palletized, open the upper part of the two suspension ring buckles 36, and retract the conveying components 4 on both sides to close to the frame. On both sides of the body 31, the two suspension pin rods 47 will fall into the suspension ring buckle 36 of the lower part, and then close the structure of the upper part and screw the locking screw to lock the two parts of the suspension ring buckle 36, and then push the device to move. The corresponding second motor 45 can be controlled to start and stop according to demand. When encountering a slope, the second support wheel 11 at the bottom end of the front guide plate 8 first contacts the slope, and the angle of the front guide plate 8 changes, causing the inner slider 132 to move in the tilted direction, thereby compressing the inner airbag 133 on one side of the movement, which will cause the corresponding connected second trigger airbag 137 or The first trigger airbag 136 expands, which in turn pushes the extension rod 128 to drive the bottom plate 122 to move. In this way, while compressing the return spring 123, the support bottom block 125 and the support top block 127 are gradually staggered. Finally, when the support top block 127 falls into the supporting groove 124, the limit tooth at the top of the limit card plate 126 will disengage from the limit card groove 37, releasing the rotation restriction on the bottom end of the frame body 31. In this way, when the base platform 1 moves to the slope, the outer frame assembly 3 as a whole and the goods inside it will be suspended on the top of the ring buckle 36 and the suspension pin rod 47. The vertical state is maintained in the suspended state, thereby preventing the center of gravity of the goods from tilting when the entire transport device is on an inclined surface, causing the transport device to be unable to adapt to the slope transportation. The movement of the extension rod 128 will also drive the connecting rod 64 to move, and then drive the straight plate 62 as a whole and all the driving gears 63 to move, so that the driving gear 63 at the bottom will engage with the driven gear 103, and at the same time, the second motor 45 will be started, and its driving force will be transmitted to the roller 102 to assist in driving the entire transport device, thereby improving the convenience, reliability and use effect of the transport device.
