[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled person in the art without making creative labor belong to the scope protected by the utility model.

[0030] Based on the defects recorded in the prior art, the specific drawings will be combined below Figures 1-4 A preferred embodiment of the utility model cargo platform is described in detail.

[0031] As Figures 1-4 shown, it is a schematic diagram of the structure of a preferred embodiment of the utility model cargo platform. The cargo platform includes a cargo platform body 1, a telescopic fork 2 and a driving mechanism.

[0032] The cargo platform body 1 includes a cargo surface 12, which has four guide connecting columns 11 above and is fixedly connected with the cargo surface 12. The cargo platform body 1 is used for the cargo platform of the four-column hoist, wherein the cargo surface 12 is of a rectangular structure, the guide connecting columns 11 are fixedly arranged at the corners of the cargo surface 12, and the four guide connecting columns 11 are evenly distributed, which improves the overall stability of the equipment and can carry heavy goods, with small shaking during operation, reduced risk of goods falling or equipment failure, wider application range and long service life.

[0033] The driving mechanism and the telescopic fork 2 are both arranged above the cargo surface 12 and fixedly connected with the cargo surface 12. The driving mechanism is drivingly connected with the telescopic fork 2. The driving mechanism of the embodiment provides telescopic power for the telescopic fork 2. The driving mechanism drives the telescopic fork 2 to extend outward or retract inward relative to the cargo surface 12.

[0034] Continuing to refer to Figures 1-4As shown, the telescopic fork 2 of the embodiment includes a fixed frame 23, a primary fork 21 and a secondary fork 22.

[0035] The fixed frame 23 is fixedly arranged on the upper surface of the loading surface 12 and located between the guide connecting columns 11 at a preset distance, which is the length of the plate-shaped structure. The fixed frame 23 is fixed to the upper surface of the loading surface 12 by the cooperation of a fixed block and a screw or bolt.

[0036] The primary fork 21 is preferably a strip-shaped block and is slidably arranged on the upper surface of the fixed frame 23, i.e., the primary fork 21 can slide relative to the fixed frame 23. The driving force of the primary fork 21 is provided by the driving mechanism.

[0037] The secondary fork 22 is located above the primary fork 21 and is linked with the primary fork 21. The linkage means moving towards the loading platform body 1 or away from the loading platform body 1. The secondary fork 22 has a strip-shaped sliding groove matched with the strip-shaped block of the primary fork 21. For example, when the primary fork 21 extends away from the loading platform body 1, the chain on the primary fork 21 also starts to lengthen, and the roller rotates at any time to drive the secondary fork 22 to move outward relative to the primary fork 21. When the primary fork 21 retracts towards the loading platform body 1, the chain on the primary fork 21 also starts to shorten, and the roller rotates at any time to drive the secondary fork 22 to move inward relative to the primary fork 21.

[0038] In detail, the driving mechanism of the embodiment includes a motor 3, a speed reducer 4 and a gear rack module. The motor 3 is in transmission connection with the speed reducer 4, the speed reducer 4 is in transmission connection with the gear rack module, and the gear rack module is in driving connection with the primary fork 21.

[0039] The transmission connection between the motor 3 and the speed reducer 4 is common in the prior art, and the gear rack module is also common in the prior art. The gear rack module includes a gear and a rack. The rack is fixed below the primary fork 21, and the gear is fixed on the speed reducer 4.

[0040] For example, the motor 3 is started, the terminal sprocket of the motor 3 rotates, the chain transmission is driven by the sprocket of the motor 3, and then the terminal sprocket of the speed reducer 4 is driven to rotate. The gear is fixedly connected on the speed reducer 4 and rotates with the gear. The rack moves with the rotation of the gear through the gear transmission, and the primary fork 21 moves with the rack. Since the roller is installed between the primary fork 21 and the secondary fork 22, the secondary fork 22 also moves.

[0041] It should be noted that in order to strengthen the support of the primary fork 21 and the secondary fork 22, the fixing frame 23, the primary fork 21 and the secondary fork 22 of the embodiment are arranged in pairs at a predetermined distance, and the speed reducer 4 is connected with the primary fork 21 in pairs through two groups of gear and rack modules. The specific transmission connection mode has been described above.

[0042] The following will explain in detail how the primary fork 21 links the secondary fork 22. A roller is arranged between the primary fork 21 and the secondary fork 22. When the primary fork 21 moves relative to the fixing frame 23, the roller rotates to drive the secondary fork 22 to move relative to the primary fork 21.

[0043] The specific process is as follows: when it is necessary to transfer the goods, the horizontal type stereoscopic storage robot can directly put down the goods after the goods are brought to the entrance of the vertical type stereoscopic storage robot, and then the next instruction is completed; after the vertical type stereoscopic storage robot arrives, the telescopic fork 2 (the primary fork 21 and the secondary fork 22 are simultaneously extended) is driven by the motor 3 to lift the goods and pull them back into the vertical type stereoscopic storage robot, so as to transfer the goods, and after reaching the target layer, the goods are placed on the shelf by the telescopic fork 2, and the horizontal type stereoscopic storage robot of this layer is used for carrying.

[0044] As a preferred embodiment, the upper surface of the secondary fork 22 can be additionally provided with a guide rail 221, and the guide rail 221 of the embodiment can be connected with the guide rail 221 of the shelf.

[0045] When it is necessary to transfer the horizontal type stereoscopic storage robot, the horizontal type stereoscopic storage robot moves to the entrance of the vertical type stereoscopic storage robot, and after the vertical type stereoscopic storage robot arrives, the telescopic fork 2 remains stationary, the guide rail 221 on the telescopic fork 2 is connected with the guide rail 221 on the shelf, the horizontal type stereoscopic storage robot moves along the guide rail 221 and enters the inside of the vertical type stereoscopic storage robot; the vertical type stereoscopic storage robot is transferred to the target layer, the telescopic fork 2 remains stationary, the guide rail 221 on the telescopic fork 2 is connected with the guide rail 221 on the shelf, the horizontal type stereoscopic storage robot moves along the guide rail 221 and leaves the vertical type stereoscopic storage robot to complete the instruction in the target layer.

[0046] When the horizontal stereoscopic storage robot needs to be transferred to the layer, the horizontal stereoscopic storage robot with goods moves to the vertical stereoscopic storage robot entrance, waits for the vertical stereoscopic storage robot to arrive, the telescopic fork 2 remains stationary, the guide rail 221 on the telescopic fork 2 is connected with the guide rail 221 on the goods shelf, the horizontal stereoscopic storage robot with goods moves along the guide rail 221 and enters the vertical stereoscopic storage robot; the vertical stereoscopic storage robot is transferred to the target layer, the telescopic fork 2 remains stationary, the guide rail 221 on the telescopic fork 2 is connected with the guide rail 221 on the goods shelf, the horizontal stereoscopic storage robot with goods moves along the guide rail 221 and leaves the vertical stereoscopic storage robot, and the instruction in the target layer is completed.

[0048] When the lifting machine needs to transfer the four-way vehicle 7 with goods, the goods and the four-way vehicle cannot enter at the same time, the goods and the four-way vehicle 7 need to be separated, and there is a front and rear situation. When the goods and the four-way vehicle 7 enter the lifting machine, the plane of the goods and the four-way vehicle 7 has a height difference, and the lifting machine needs to be adjusted in height when entering.

[0049] Different from the lifting machine loading platform in the prior art, the upper surface of the loading platform in the embodiment has the guide rail 221, the guide rail 221 can be directly connected with the guide rail 221 of the four-way vehicle, the four-way vehicle with goods can be directly moved to the loading platform in the embodiment, the four-way vehicle with goods does not need to be separated from the goods, and the lifting machine does not need to be adjusted in height.
