[0002] A forklift refers to a variety of wheeled handling vehicles that are used for loading and unloading, stacking, stacking and short-distance transportation of palletized cargo. It is widely used in factory workshops, warehouses, circulation and distribution centers, ports, stations, airports, freight yards, etc. It is an indispensable equipment for pallet transportation and container transportation.

[0003] However, when a stacker with existing technology is transporting large goods, the fork arm of the stacker is smaller than the cargo chassis, resulting in the fork arm being unable to provide sufficient stability for the large goods during transportation. Workers are required to slow down during transportation and pay close attention to the large goods on the fork arm when turning to prevent the large goods from tilting and shifting on the fork arm, or even causing the stacker to tip over and cause damage. Based on this, a stacker with a double support structure is proposed to solve the above problem. Utility Model Content

[0029] Example 1

[0030] like Figures 1 to 6As shown, an embodiment of the present invention provides a stacker with a dual support structure, including a stacker body 1, one side of the stacker body 1 is fixedly connected to an outer door frame 2, the inner side of the outer door frame 2 is slidingly connected to an inner door frame 3, the inner side of the inner door frame 3 is fixedly connected to a fork arm frame 4, and one side of the fork arm frame 4 is fixedly connected to a fork arm 5; a support assembly, the support assembly is used to assist the fork arm 5 in supporting the cargo, and the support assembly is respectively connected to the fork arm frame 4 and the fork arm 5. The utility model has the advantages of increasing the cargo support range and improving the cargo transportation stability through the arrangement of the support assembly, and the support assembly is a deformable structure, and will not be blocked by the cargo chassis support feet when the fork arm 5 is inserted into the cargo chassis, and the support assembly will automatically avoid when it touches the cargo chassis support feet during the deformation process, and will not cause the support assembly to be stuck or damaged.

[0031] like Figure 4 and Figure 6 As shown, the support assembly includes a mounting member 6, which is sleeved on the outer wall of the fork arm 5, and the mounting member 6 is fixedly connected to one side of the fork arm frame 4. A connecting member 7 is fixedly connected to one side of the mounting member 6, and a pressure block 8 is slidably connected to the inside of the connecting member 7. The horizontal height of the pressure block 8 is higher than the fork arm 5. An air bag 9 is provided at the bottom of the pressure block 8, and the air bag 9 is provided inside the connecting member 7. A push member 10 is slidably connected to the inside of the connecting member 7, and the push member 10 is provided on one side of the air bag 9. The overall outline of the push member 10 is an "E"-shaped outline. A connecting rod 11 is inserted into the inside of the push member 10, and one side of the connecting rod 11 is fixedly connected to a rotating Part 12, the rotating part 12 is rotatably connected to the inside of the connecting part 7, the outer wall of the rotating part 12 is rotatably connected to the support plate 13, the inside of the support plate 13 is provided with a card slot 14, and the inside of the card slot 14 is plugged with a card part 15. Through the setting of the inward-concave arc plate on the card part 15, the card part 15 can be deformed and contracted after being subjected to a certain pressure, and stop contacting with the card slot 14, so that the support plate 13 can avoid the cargo chassis support foot to prevent the support assembly from getting stuck. The card part 15 is plugged into the top of the rotating part 12, and a return spring 16 is fixedly installed inside the connecting part 7, and the return spring 16 is fixedly connected to one side of the push member 10.

[0032] like Figure 4 As shown, the outer wall of the support plate 13 is fixedly connected to a limiting block 17. Through the setting of the limiting block 17, the support plate 13 can be limited after the support plate 13 rotates ninety degrees, so that the support plate 13 stops rotating. The outer wall of the mounting member 6 is fixedly connected to a stabilizing block 18. Through the setting of the stabilizing block 18, the support plate 13 can be limited by the limiting block 17 after the support plate 13 rotates ninety degrees and the limiting block 17 is rotated to the bottom of the stabilizing block 18, thereby improving the supporting force of the support plate 13.

[0033] Working steps

[0034] Step 1. When the staff controls the forklift to transport the goods, the staff first controls the forklift to insert the fork arm 5 into the cargo chassis, and then controls the fork arm 5 to rise to lift the cargo chassis and the goods. In this process, since the horizontal height of the pressing block 8 is higher than the fork arm 5, the pressing block 8 will first contact the cargo chassis, so that the pressing block 8 is squeezed by the cargo chassis, and then the pressing block 8 is pressed into the interior of the connecting member 7 and squeezes the airbag 9 to deform, so that the airbag 9 is deformed and moves inside the connecting member 7, so that the airbag 9 pushes the pushing member 10 to move along the inside of the connecting member 7. The movement of the connecting member 7 will squeeze the reset spring 16 to contract and drive the rotating member 12 to rotate through the connecting rod 11. The rotation of the rotating member 12 will drive the card member 15 to rotate, so that the card member 15 passes through the card slot 14. The movable support plate 13 rotates until the support plate 13 rotates ninety degrees and stops after being perpendicular to the side of the fork arm 5. At this time, the limit block 17 on the support plate 13 is blocked by the mounting member and rotates to the bottom of the stabilizing block 18. At the same time, the support plate 13 is deformed in the process of the fork arm 5 lifting the goods, so that the support plate 13 will not rub against the cargo chassis during the rotation and deformation process, thereby reducing the force required for the rotation and deformation of the support plate 13. When the support plate 13 is rotated and deformed, it will cooperate with the fork arm 5 to lift the goods. At this time, the support plate 13 will cooperate with the fork arm 5 to increase the support range of the cargo chassis, thereby improving the support stability of the goods and preventing the goods from shaking and tilting due to insufficient stability when the forklift is transporting the goods, thereby affecting the transportation of the goods by the staff.

[0035] It should be noted that when the chassis on which the workers need to transport goods is small, and the support plate 13 is blocked by the cargo chassis legs during rotation, the support plate 13 is blocked and limited. At this time, the card 15 driven by the rotating part 12 cannot drive the support plate 13 to rotate through the card slot 14. The card 15 will be relatively squeezed by the card slot 14, causing the card 15 to deform and shrink and no longer contact the card slot 14, preventing the support component from getting stuck during the deformation process, causing the deformed component to be crushed by the goods.

[0036] Step 2. When the staff completes the transportation of the goods by the forklift and unloads the goods, the fork arm 5 and the support plate 13 stop contacting with the cargo chassis, so that the pressure block 8 loses the pressure of the cargo chassis, and then the reset spring 16 restores and pushes the push piece 10 to reset, so that the push piece 10 drives the rotating piece 12 to rotate and reset through the connecting rod 11 and squeezes the airbag 9, so that the airbag 9 is squeezed and restored, and the airbag 9 pushes the pressure block 8 to rise and reset, and the rotation and reset of the rotating piece 12 will eventually drive the support plate 13 to rotate and reset through the clamping piece 15, until the support plate 13 rotates ninety degrees and stops parallel to the fork arm 5.

[0037] In summary, the utility model has the advantages of increasing the cargo support range and improving the stability of cargo transportation. The support component is a deformable structure, and will not be blocked by the cargo chassis support feet when the fork arm 5 is inserted into the cargo chassis. When the support component touches the cargo chassis support feet during the deformation process, it will automatically avoid it, and will not cause the support component to be stuck and damaged.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
