For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figures 1 to 3 As shown, this embodiment provides a cargo lifting device, which can improve the transportation efficiency of cargo 100 without increasing the number of elevators 1 and reduce the equipment investment cost. The cargo lifting device includes an elevator 1 and a cargo loading device.

[0043] Among them, see Figure 1 The cargo-carrying device can be raised and lowered on the hoist 1, and the cargo-carrying device includes a carrier frame 2 and a cargo transfer mechanism 3 arranged on the carrier frame 2. A first station 23 and a second station 24 are arranged on the carrier frame 2. The first station 23 is used to store and transport cargo 100, and the second station 24 is used to cache cargo 100. The cargo transfer mechanism 3 can move the cargo 100 on the first station 23 to the second station 24, and the cargo transfer mechanism 3 can move the cargo 100 on the second station 24 to the first station 23.

[0044] like Figure 1 and Figure 2 As shown, when transporting goods 100, a group of goods 100 can be first transported from the conveyor line to the first station 23, and then the goods transfer mechanism 3 moves the goods 100 on the first station 23 to the second station 24 for buffering. At this time, the first station 23 is vacant, and another group of goods 100 can be transported from the conveyor line to the first station 23 again. After the elevator 1 works to lift the cargo device to a preset height, the goods 100 on the first station 23 are first transported to the outside of the elevator 1 (such as a shelf in a warehouse), and then the goods 100 on the second station 24 are transferred to the first station 23 by the goods transfer mechanism 3, and the group of goods 100 is then transported to the outside of the elevator 1 via the first station 23.

[0045] That is to say, the cargo lifting device can transport two groups of cargo 100 in one way, effectively improving the transportation efficiency of the cargo 100, and there is no need to increase the number of transport stations and elevators 1 on the production conveyor line, which can reduce the equipment investment cost and save equipment space. At the same time, when the number of transported cargo 100 is fixed, the cargo lifting device can effectively reduce the number of lifts of the elevator 1, extend the service life of the elevator 1, and reduce the equipment maintenance cost.

[0046] Optionally, see Figure 1The hoist 1 includes a support frame 11, a third driving member 12 and a transmission mechanism 13 arranged on the support frame 11, and the output end of the third driving member 12 is transmission-connected with the cargo device through the transmission mechanism 13 to drive the cargo device to rise and fall relative to the support frame 11. In this embodiment, the transmission mechanism 13 includes a transmission chain 131 and a transmission sprocket 132 that are transmission-connected, and the transmission sprocket 132 is arranged at the turning position of the transmission chain 131 on the support frame 11 to change the transmission direction of the transmission chain 131. The free end of the transmission chain 131 is connected to the load-bearing frame 2, and the output end of the third driving member 12 is transmission-connected with the transmission sprocket 132 to drive the transmission chain 131 to drive, thereby driving the load-bearing frame 2 to rise and fall relative to the support frame 11.

[0047] Furthermore, the support frame 11 includes a base 111 and a stand 112 disposed on the base 111, the transmission sprocket 132 and the transmission chain 131 are both arranged on the stand 112, and the third driving member 12 is fixed to the base 111. Figure 1 As shown, a cargo outlet 1122 is provided at the upper end of the stand 112. When the carrier 2 rises to the first station 23 and faces the cargo outlet 1122, the cargo 100 on the first station 23 is output to the outside of the elevator 1. Exemplarily, the third driving member 12 is a rotary motor.

[0048] Optionally, see Figure 2 and Figure 3 The carrier frame 2 includes a bottom frame 21 and a support beam frame 22 disposed on the bottom frame 21. The first station 23 and the second station 24 are arranged side by side on the bottom frame 21 and are located below the support beam frame 22. The cargo transfer mechanism 3 is disposed on the support beam frame 22. An entry and exit space for cargo 100 is formed between the bottom frame 21 and the support beam frame 22. The bottom frame 21 is used to carry the cargo 100 on the first station 23 and the second station 24. The support beam frame 22 provides an installation foundation for the cargo transfer mechanism 3. The bottom frame 21 is slidably connected to the support frame 11 of the hoist 1 to carry the cargo 100 relative to the vertical frame 112 of the hoist 1 to achieve the transportation of the cargo 100.

[0049] Optionally, see Figure 1 and Figure 2 The cargo transfer mechanism 3 includes a first moving assembly 31 and a second moving assembly 32 spaced apart on the carrier 2. The first moving assembly 31 is used to move the cargo 100 at the first station 23 to the second station 24, and the second moving assembly 32 is used to move the cargo 100 at the second station 24 to the first station 23. The first moving assembly 31 and the second moving assembly 32 work independently of each other without interfering with each other, which can improve the efficiency of cargo 100 movement.

[0050] In other embodiments, the cargo transfer mechanism 3 may also be provided with only one moving component, and the cargo 100 to be transferred may be reciprocated between the first workstation 23 and the second workstation 24 by the same moving component.

[0051] In this embodiment, the first moving assembly 31 and the second moving assembly 32 have the same structure, see Figure 2 and Figure 3 Taking the first moving assembly 31 as an example, it includes a first driving member 311 and a push plate assembly 312. The first driving member 311 is arranged on the carrier 2. The push plate assembly 312 is configured to contact the goods 100 to be moved. The output end of the first driving member 311 is connected to the push plate assembly 312, which is used to drive the push plate assembly 312 to drive the goods 100 to move between the first station 23 and the second station 24. The push plate assembly 312 of the first moving assembly 31 is located on the side of the goods 100 facing away from the second station 24, and the push plate assembly 312 of the second moving assembly 32 is located on the side of the goods 100 facing away from the first station 23. With such a configuration, the push plate assembly 312 only needs to translate and push the goods 100 to move, and the control is simple and easy to implement. In addition, when the push plate assembly 312 is not in use, it can be moved to the side of the first station 23 (the second station 24) without interfering with the input and output of the goods 100.

[0052] Exemplarily, the first driving member 311 is a cylinder, the cylinder body of which is fixed to the supporting beam 22 of the carrier 2 through a support plate, and the output rod of the cylinder is connected to the push plate assembly 312, so as to linearly drive the push plate assembly 312 to push the cargo 100 to translate between the first station 23 and the second station 24. In other embodiments, the first driving member 311 may also be a linear driving member such as an electric cylinder, a lead screw nut mechanism, etc.

[0053] Optionally, see Figure 3 The push plate assembly 312 includes a fixed plate 3121 and a push plate 3122 that are parallel and spaced apart. The active surface of the push plate 3122 faces the goods 100 and extends along the conveying direction of the goods 100. The fixed plate 3121 and the push plate 3122 are connected and fixed by a first connecting plate 3123. The fixed plate 3121 is connected to the output end of the first driving member 311 by a second connecting plate 3124. Figure 2 In the direction of the goods 100, the conveying direction of the goods 100 is the front-to-back direction, and the active surface of the push plate 3122 is the surface in contact with the goods 100. Since the push plate 3122 extends in the front-to-back direction, there can be enough contact area between it and the goods 100, so that the goods 100 can be pushed to move horizontally stably to prevent the goods 100 from tipping over. Exemplarily, the length of the push plate 3122 is slightly smaller than the length of the first station 23 in the conveying direction of the goods 100, and the push plate 3122 is long enough to push multiple goods 100 arranged in the front-to-back direction at one time, thereby improving the transfer efficiency.

[0054] In this embodiment, refer to Figure 3 , a first connecting plate 3123 is provided at each end of the fixing plate 3121 to improve the connection stability. The first connecting plate 3123 is an L-shaped plate, the short side of the L-shaped plate is fitted and connected to the fixing plate 3121, and the long side of the L-shaped plate is fitted and connected to the push plate 3122, and both are in surface contact, and the connection is firm. Furthermore, a right-angled triangle reinforcement plate is also provided in the L-shaped space of the L-shaped plate to enhance the support stability of the first connecting plate 3123.

[0055] Furthermore, the second connecting plate 3124 is also an L-shaped plate, the short side of the L-shaped plate is fitted and connected to the fixing plate 3121 , and the long side of the L-shaped plate is fixedly connected to the output end of the first driving member 311 .

[0056] Optionally, see Figure 3 , a flexible pad 3125 is provided on the side of the push plate 3122 facing the cargo 100, and the flexible pad 3125 contacts the cargo 100. The flexible pad 3125 can buffer the force between the push plate 3122 and the cargo 100, avoid rigid contact between the push plate 3122 and the cargo 100, and prevent the cargo 100 from being damaged by collision. Exemplarily, the flexible pad 3125 is a rubber pad or a silicone pad.
