Description

Technical Field

[0001] This utility model belongs to the field of warehouse trolley technology, specifically referring to a warehouse trolley for easy pickup in logistics supply chain. Background Technology

[0002] Logistics supply chain workers often need to use warehouse carts to transport multiple packages at once. Currently, most warehouse carts have two-layer shelves, and each shelf is equipped with guardrails, allowing warehouse carts to transport more packages at once, and the guardrails can prevent packages from falling.

[0003] In existing technologies, warehouse trolleys used in logistics supply chains have poor compatibility with special goods. The packaging boxes of regular goods are mostly of a fixed shape, which makes them relatively stable during transportation. However, for a small number of irregularly shaped goods, it is inconvenient to pull them out of the warehouse trolley, as it lacks auxiliary functions and is more likely to fall off when moving.

[0004] Meanwhile, continuous handling of goods is inconvenient due to the depth of the goods placed on the shelves. This is especially true for goods placed at higher levels, which increases the difficulty of manual loading and unloading. Utility Model Content

[0005] The technical problem this invention aims to solve is that warehouse trolleys used in logistics supply chains have poor compatibility with irregularly shaped goods, are inconvenient to pick up due to their size and weight, and are limited by placement position and depth, thus affecting operational efficiency.

[0006] The technical solution adopted by this utility model is as follows:

[0007] This utility model proposes a warehouse trolley for easy pickup in logistics supply chain, including a mobile frame with wheels fixedly connected to the lower part of the mobile frame, and a picking auxiliary unit. The picking auxiliary unit includes a placement platform located above the mobile frame, and the placement platform has several square through slots arranged in an array. A U-shaped frame is movably inserted into the lower part of the square through slots, and auxiliary wheels are rotatably installed inside the U-shaped frame.

[0008] Furthermore, an adjustment plate is provided below the placement platform, and a cross-shaped slot is provided on the adjustment plate to engage with the U-shaped frame. A threaded rod is fixedly connected to the lower part of the U-shaped frame, which passes through the cross-shaped slot, and a nut is screwed onto the threaded rod.

[0009] Furthermore, a support platform is fixedly connected to the upper part of the mobile frame, and the placement platform is fixedly connected to the upper end of the two support platforms. A limiting groove is opened on the support platform, and a sliding rod that is fixedly connected to the adjustment platform is slidably provided on the limiting groove.

[0010] Furthermore, a connecting platform is fixedly connected to the inner side of the support platform, an electric push rod is fixedly connected to the connecting platform, and push plates disposed on both sides of the adjustment platform are fixedly connected to the output end of the electric push rod.

[0011] Furthermore, a cylinder is fixedly connected to the upper part of the mobile frame and arranged opposite to it on the outside of the support platform. An upper frame is fixedly connected to the output end of the cylinder. A rotating rod is rotatably provided on the inner wall of the upper frame. A support plate is fixedly connected to the rotating rod. A locking block is fixedly connected to the side of the support plate away from the rotating rod. Guardrails are fixedly connected to both sides of the upper frame.

[0012] Furthermore, a strip-shaped slot is provided on the placement platform, and a partition baffle that is movably inserted into the strip-shaped slot is fixed to the lower part of the upper frame.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. By setting up a retrieval auxiliary unit, irregularly shaped parts or heavier goods can be easily retrieved by the rolling of auxiliary wheels. In conjunction with the lifting of the upper frame and the partition baffle, a sandwich layer is formed to provide protection.

[0015] 2. The goods are placed on a sloping support plate. Under the influence of gravity, the goods can slide naturally to a lower position after being picked up, which facilitates continuous picking operations. Attached Figure Description

[0024] Example 1:

[0025] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 As shown, the present invention proposes a warehouse trolley for easy pickup in logistics supply chain, including a mobile frame 1, with mobile wheels 11 fixedly connected to the lower part of the mobile frame 1, and also includes a picking auxiliary unit. The picking auxiliary unit includes a placement platform 2 located above the mobile frame 1. The placement platform 2 has several square through slots 21 arranged in an array. A U-shaped frame 22 is movably inserted into the lower part of the square through slots 21. An auxiliary wheel 23 is rotatably installed inside the U-shaped frame 22.

[0026] For irregularly shaped and large goods, pulling them is inconvenient, especially for heavy goods. The resistance to pulling the goods can be reduced by the rolling assistance of the auxiliary wheels 23 inside the U-shaped frame 22 that pass through the square slot 21.

[0027] Below the placement platform 2 is an adjustment platform 3. The adjustment platform 3 has a cross-shaped groove 31 that engages with the U-shaped frame 22. The lower part of the U-shaped frame 22 is fixedly connected to a threaded rod 32 that passes through the cross-shaped groove 31. A nut 33 is screwed onto the threaded rod 32.

[0028] It should be noted that, since the square through slot 21 is square, the U-shaped frame 22 can still pass through after rotating 90 degrees. After rotating the U-shaped frame 22 by the threaded rod 32, it is locked in the cross-shaped slot 31 for limitation. At the same time, the nut 33 is tightened to fix it. After changing the direction of the auxiliary wheel 23, the direction of picking up different goods can be adjusted, which can be used flexibly.

[0029] like Figure 4 , 5As shown, a support platform 4 is fixedly connected to the upper part of the mobile frame 1, and the placement platform 2 is fixedly connected to the upper end of the support platforms 4 on both sides. A limiting groove 41 is opened on the support platform 4, and a sliding rod 42 fixedly connected to the adjusting platform 3 is slidably provided on the limiting groove 41. A connecting platform 5 is fixedly connected to the inner side of the support platform 4, and an electric push rod 51 is fixedly connected to the connecting platform 5. Push plates 52 arranged on both sides of the adjusting platform 3 are fixedly connected to the output end of the electric push rod 51.

[0030] The output end of the electric push rod 51 can be extended to push the push plate 52 to move the adjustment platform 3 upward as a whole, so that the U-shaped frame 22 can pass through the square through slot 21 for use. The limiting slide groove 41 limits the sliding rod 42 and controls the rising height of the adjustment platform 3, so that only the rotating part of the auxiliary wheel 23 is higher than the upper part of the placement platform 2.

[0031] Example 2:

[0032] like Figure 1 , 2 As shown in Figure 3, a cylinder 6 is fixedly connected to the upper part of the mobile frame 1, located on the outside of the support platform 4 and arranged opposite to it. An upper frame 61 is fixedly connected to the output end of the cylinder 6. A rotating rod 62 is rotatably provided on the inner wall of the upper frame 61. A support plate 63 is fixedly connected to the rotating rod 62. A locking block 64 is fixedly connected to the side of the support plate 63 away from the rotating rod 62. Guardrails 65 are fixedly connected to both sides of the upper frame 61.

[0033] It should be noted that the angle of the support plate 63 can be adjusted by rotating the rotating rod 62 to form an inclination of 10-20 degrees. The inclination angle is determined by the position of the rotating rod 62 and the height of the upper frame 61. The locking block 64 is locked at the edge of the upper frame 61. When the placed goods are taken out, the goods at the front of the bottom are taken out in sequence. The goods behind can be easily pushed and slide down freely due to gravity, which is convenient for continuous taking out.

[0034] like Figure 4 As shown, the placement platform 2 is provided with a strip slot 7, and the lower part of the upper frame 61 is fixedly connected to a partition baffle 71 that is movably inserted into the strip slot 7. When the upper frame 61 is lowered, the partition baffle 71 can be inserted into the corresponding strip slot 7 to form a frame-like structure to protect the goods on the placement platform 2 and prevent them from falling. At the same time, the height of the partition baffle 71, which forms a kind of interlayer space, can be freely controlled according to the lifting height.

[0035] The above is the entire process of using a warehouse trolley for easy pickup in a logistics supply chain.
