In this embodiment, multiple groups of pushing assemblies are provided, and the multiple groups of pushing assemblies are used to be distributed along the horizontal movement direction of the cargo platform. In this embodiment, two groups of pushing assemblies are provided, and the two groups of pushing assemblies are used to be respectively arranged at the two ends of the cargo platform along the horizontal movement direction. The two groups of pushing assemblies have the same structure. The pushing assemblies include pushing parts for being arranged on both sides of the cargo platform. The pushing parts are connected to the power mechanism through a transmission mechanism. The power mechanism is used to be arranged on the cargo platform. The power mechanism can drive the pushing parts on both sides of the cargo platform to perform synchronous telescopic movements through the transmission mechanism.

[0034] The transmission mechanism includes a guide seat 2, which is fixed on a guide seat support plate 3. The guide seat support plate 3 is used to be fixed to the cargo platform. A gear 4 is provided inside the guide seat 2. The upper side of the gear 4 is engaged with the first rack shaft 5, and the lower side of the gear is engaged with the second rack shaft 6. The first rack shaft 5 and the second rack shaft 6 pass through the guide seat 2 and are slidably connected to the guide seat 2. The rotation of the gear 4 can drive the first rack shaft 5 and the second rack shaft 6 to move toward or away from each other synchronously.

[0035] The first rack shaft 5 and the second rack shaft 6 have the same structure and both include a movable shaft. The movable shaft adopts a cylindrical shaft and an anti-rotation guide groove is provided on its axial surface. Correspondingly, a protrusion 7 is provided inside the guide seat 2, and the protrusion 7 is embedded in the anti-rotation guide groove. The movable shaft is slidably connected to the guide seat 2 through the anti-rotation guide groove and the protrusion, so that the movable shaft can only move linearly along its own axis and will not rotate around its own axis.

[0036] A rack structure is provided on the axial surface of the movable shaft. The rack structure is provided along the axial direction of the movable shaft and meshes with the gear 4 .

[0037] The first rack shaft 5 is connected to the first pushing member 8, and the second rack shaft 6 is connected to the second pushing member 9. The first pushing member 8 and the second pushing member 9 are two pushing members of the pushing assembly. The first pushing member and the second pushing member are located on both sides of the guide seat 2. The first pushing member 8 is used to abut against the shelf on one side of the alley, and the second pushing member 9 is used to abut against the shelf on the other side of the alley so that the loading platform remains stable when picking up and placing goods.

[0038] The first pushing member 8 and the second pushing member 9 are non-coaxially arranged or coaxially arranged. In this embodiment, the first pushing member 8 and the second pushing member 9 are coaxially arranged. In order to enable the first pushing member 8 and the second pushing member 9 to remain coaxial, the end of the first rack shaft 5 is vertically fixed to one end of the first connecting member 10, the other end of the first connecting member 10 is vertically fixed to the first pushing member, the end of the second rack shaft 6 is vertically fixed to one end of the second connecting member 11, and the other end of the second connecting member 11 is vertically fixed to the second pushing member.

[0045] A synchronization shaft 1 is provided between the gears of the two thrust assemblies, and the gear 4 is fixed on the synchronization shaft 1. The synchronization shaft 1 enables the gears of the two thrust assemblies to rotate synchronously. The synchronization shaft 1 is rotationally connected to the guide seat 2 through a bearing 15.

[0046] The synchronous shaft 1 is connected to a rotating drive member, which is used to drive the synchronous shaft to rotate. The rotating drive member and the synchronous shaft together constitute a power mechanism.

[0047] The rotating drive member adopts a device that can output rotational motion, such as an electric motor or a hydraulic motor, and preferably adopts a motor 16. The motor 16 is fixed on a power mechanism support plate 17, and the power mechanism support plate 17 is used to be fixedly connected to the cargo platform. The output shaft of the motor 16 is connected to the synchronous shaft 1 through a power transmission mechanism 18. The power transmission mechanism 18 adopts a belt drive mechanism or a chain drive mechanism, and preferably adopts a belt drive mechanism.

[0048] The motor 16 can drive the synchronous shaft 1 to rotate, thereby driving the gears 4 of the two pushing assemblies to rotate, and further driving the two pushing assemblies to perform synchronous movement.

[0049] In the cargo platform stabilization mechanism of this embodiment, the pushing parts of all the pushing assemblies are driven by a common motor, and there is no need to configure a separate power mechanism such as a motor, which greatly reduces the number of power mechanisms used and reduces the equipment investment cost.

The first wire rope wound on the winch wheel 19 is wrapped around 23 and passed through the first steering wheel 20 and connected to the rear end of the first pushing member 8, the second wire rope wound on the winch wheel 19 is wrapped around 24 and passed through the second steering wheel 21 and connected to the rear end of the second pushing member 9, the third wire rope 25 wound on the winch wheel 19 is connected to the front end of the second pushing member 9 after passing through the third steering wheel 22, and the fourth wire rope 26 wound on the winch wheel is connected to the front end of the first pushing member 8 after passing through the third steering wheel 22. The four wire ropes constitute a wire rope assembly. The rotation of the winch wheel 19 can drive the first pushing member 8 and the second pushing member 9 to move toward or away from each other synchronously.

[0053] When the transmission mechanism is provided with multiple, multiple winch wheels 19 are connected by a synchronization shaft, and the synchronization shaft is connected to the rotation drive member. The three steering wheels are all connected to the support plate, and the support plate is used to be fixedly connected to the cargo platform.
