[0045] When the present invention is in use:

[0046] When assembling a small wheelbase forklift, the wheelbase of the small wheelbase forklift is W1. At this time, the installation groove 20 on the flat plate 2 is in an idle state, that is, the mobile cushion plate assembly 10 is in an uninstalled state. Then, the key groove below the moving plate 11 is in clearance fit with the connecting key 4 on the fixed cushion plate 5, and the moving plate 11 is moved towards the installation groove 20 until the moving plate 11 contacts the flat plate 2. Then, the key groove below the mobile cushion plate assembly 10 is in clearance fit with the connecting key 4 and is pushed towards the installation groove 20 until the mobile cushion plate assembly 10 is pushed until it contacts the moving plate 11. The mobile cushion plate assembly 10 and the fixed cushion plate 5 are tightly connected by bolts 12, as Figure 20 、 24 shown. Then, the left cushion block 13, the right cushion block 15 and the mobile cushion plate assembly 10 are tightly fastened by bolts 12, and the three form a T-shaped groove, as Figures 11-13 shown; the support rib plate 14 is inserted into the T-shaped groove to form a matching relationship, asFigures 14-16 As shown, the support rib plate 14 provides effective support for the suspended part of the movable cushion plate assembly 10. At this time, the installation of the movable cushion plate assembly 10 in the ground groove is completed. As Figure 1 shown, then the small wheelbase forklift 16 with a shaft hole of W1 can be driven onto the flat plate 2. During the driving-in process, the forklift first drives onto the flat plate through the ramp 7. Since the flat plate 2 is provided with a waist-shaped retaining ring 1, the through groove 21 is surrounded by the waist-shaped retaining ring 1, so that the vehicle of the forklift can be limited, and the vehicles on both sides of the forklift can drive smoothly and safely on the platform. When the vehicle in front of the forklift drives to the upper end of the movable cushion plate 8, at this time, the forklift completely drives above the through groove 21, and then the forklift can be assembled, repaired, etc. through the ground groove.

[0047] When assembling the large wheelbase forklift 17, it is necessary to switch to the working condition of L2 opening. Remove the movable plate 11, and at the same time remove the left cushion block 13, the right cushion block 15 and the support rib plate 14. As Figure 15 shown, push the movable cushion plate assembly 10 along the connecting key 4 in the direction away from the installation groove 20 until the movable cushion plate assembly 10 contacts the flat plate 2, completing the transformation of the ground groove opening size from L1 to L2. Fix the movable cushion plate assembly 10 to the fixed cushion plate 5 through the bolt 12. As Figure 6 shown, and insert the guiding retaining ring 18 into the steel pipe 9, and fix the guiding retaining ring 18 to the steel pipe 9 through two positioning pins 21 to prevent the guiding retaining ring 18 from swinging during the driving-in process of the forklift. The function of the guiding retaining ring 18 is to guide the forklift into the appropriate position. As Figure 6 and Figure 22 shown, if it needs to be disassembled, the positioning pin 21 can be directly pulled out.

[0048] The switching of different ground groove opening sizes is realized by the free movement of the movable cushion plate assembly 10 on the connecting key 4 and the fixed cushion plate 5. The minimum size is L1, which is applicable to the small wheelbase forklift 16, and the maximum wheelbase is L2, which is applicable to the large wheelbase forklift 17.
