Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a semi-automatic material transportation device. Background Art

[0002] Logistics transportation carts are indispensable tools for handling goods in logistics warehousing and production lines. These vehicles or devices usually consist of wheels, push handles, and a loading platform, and are designed to simplify the material transportation process and reduce the need for manual handling. According to different application requirements, transportation carts have various types and structures to adapt to various handling tasks.

[0003] Under the existing technical conditions, the use of transportation carts usually relies on external machinery or manpower to place materials on the carts. However, as the materials gradually pile up to a certain height, the overly high material stack makes it difficult to continue adding materials, and there is a risk of collapse. At the same time, the overly piled-up materials may fall due to instability, increasing the danger during the operation process. This situation may not only damage the materials themselves but also cause harm to nearby workers, thus increasing the risk and complexity of the handling operation. Summary of the Utility Model

[0029] The lifting structure includes a first vertical seat 5 and a second vertical seat 6 respectively fixedly connected to the top of the mobile vehicle 1. Grooves 10 are formed on the opposite side walls of the first vertical seat 5 and the second vertical seat 6. A screw sleeve 8 is slidably connected in the groove 10. A lifting screw rod 7 is rotatably connected to the first vertical seat 5, and a slide bar 9 is fixedly connected to the second vertical seat 6. One of the screw sleeves 8 is threadedly connected to the lifting screw rod 7, and the other screw sleeve 8 is vertically slidably connected to the slide bar 9. The screw sleeve 8 is fixedly connected to the upper plate 3, and a motor 11 for driving the lifting screw rod 7 to rotate is fixedly connected to the first vertical seat 5. The settings of the groove 10 and the slide bar 9 ensure that the screw sleeve 8 and the upper plate 3 stably move vertically along the axis direction of the lifting screw rod 7 for lifting.

[0030] The moving structure includes installation frames 12 respectively fixedly connected to the first vertical seat 5 and the second vertical seat 6. A moving plate 13 is horizontally slidably connected to the installation frame 12. The moving plates 13 are arranged in pairs. The moving plate 13 is fixedly connected to the protective plate 4. The same connecting plate 14 is fixedly arranged opposite on the two moving plates 13 of the same pair. The connecting plate 14 and the moving plate 13 are fixedly connected with the same first bolt 15; the protective plate 4 is arranged below the upper plate 3 and is arranged in a staggered manner with the upper plate 3, aiming to prevent the protective plate 4 from obstructing the descending upper plate 3 and improving the flexibility of the device during use.

[0031] A transmission member with a self-locking function is provided at the top of the moving vehicle 1 for moving the moving plate 13.

[0032] The transmission member includes a vertical plate 16 fixedly connected to the top of the moving vehicle 1. A rotating rod 17 is rotatably connected to the vertical plate 16. One end of the rotating rod 17 close to the protective plate 4 is fixedly connected with a turbine 18. A pair of fixing plates 19 are fixedly connected to the vertical plate 16.

[0036] One end of the rotating rod 17 away from the turbine 18 is fixedly connected with a rotating wheel for facilitating the operation of the staff.

[0037] The functional principle of the present utility model can be described by the following operation method:

[0038] When using the device, first, the staff places the materials to be transported on the upper plate 3. After placing, the baffle plate 26 is installed by screwing the third bolt 27, so as to realize the protection of the materials on the top of the upper plate 3; then the motor 11 is started, and the motor 11 drives the lifting screw rod 7 to rotate. When the lifting screw rod 7 rotates, the two nuts 8 will drive the upper plate 3 to move vertically upward along the axis direction of the lifting screw rod 7, so as to realize the lifting adjustment of the upper plate 3.

[0039] After the upper plate 3 is lifted to an appropriate height, the remaining materials are placed on the top of the lower plate 2. Then, the operator observes the size of the materials with the naked eye and rotates the runner. The runner drives the rotating rod 17 to rotate, the rotating rod 17 drives the turbine 18 to rotate, the turbine 18 drives the worm 20 to rotate, the worm 20 drives the lead screw 21 to rotate, the lead screw 21 drives the transmission rod 22 to move, and the transmission rod 22 drives the moving plate 13 to slide within the sliding opening 25. The moving plate 13 drives the protective plate 4 to move, thereby realizing the protection of the materials on the lower plate 2.

[0040] When it is necessary to replace the protective plate 4 according to the actual size of the materials, by screwing the first bolt 15 and the second bolt 24, the moving plate 13 together with the protective plate 4 is taken out of the sliding opening 25, and the operation is simple.
