[0031] During installation, first use the door support fixture to support and fix the door body 2, then use the tensioning bolt 3 to assemble the disc spring holder 4 on the door body 2, so as to assemble the disc spring 5 between the disc spring holder 4 and the door body 2, and tighten it with the tensioning bolt 3; then use the wheel set auxiliary support 1 to assist in supporting the wheel set 7, assemble the wheel set 7 on the track 9 and move it, and use the wheel set auxiliary support 1 to keep the wheel set 7 stable; after the wheel set 7 moves into place, use the connecting bolt 6 to connect the wheel set 7 and the disc spring holder 4, so as to assemble the wheel set 7 between the door body 2 and the track 9, then loosen the tensioning bolt 3, the wheel set 7 is installed in place, and finally take out the door support fixture and the wheel set auxiliary support 1, and the disc spring wheel set installation is completed.

[0032] In this embodiment, the door support fixture can be a conventional door support and fixing device, such as a jack + wedge-shaped pad, to support and fix the door body 2. The wheel set auxiliary support 1 can be a conventional support block, which is used to support the wheel set 7 to keep the wheel set 7 stable and prevent it from swaying left and right.

[0033] Embodiment 2

[0034] This embodiment is further elaborated on the basis of Embodiment 1. As Figure 3 shown, the door body 2 is provided with a holder mounting hole 10, and the center line of the holder mounting hole 10 is aligned with the center line of the track 9, so that the track 9 and the door body 2 are aligned in the installation position.

[0035] As Figure 1 and Figure 5 shown, the top of the disc spring holder 4 is provided with a holder mounting block 11. The holder mounting block 11 penetrates upward into the holder mounting hole 10. The top of the holder mounting block 11 is connected with a limit block 13 through a mounting bolt 12. The left and right ends of the limit block 13 extend outward from the holder mounting hole 10 and abut against the top surface of the door body 2, so as to install the disc spring holder 4 on the door body 2.

[0036] As Figure 1 and Figure 5 shown, the left and right sides of the holder mounting block 11 on the disc spring holder 4 are provided with tensioning bolt mounting blocks 14. The tensioning bolt 3 passes downward through the door body 2 and is threadedly assembled on the tensioning bolt mounting block 14. The space between the tensioning bolt mounting block 14, the holder mounting block 11 and the door body 2 forms a disc spring assembly cavity, and the disc spring 5 is assembled in the disc spring assembly cavity.

[0037] As Figure 1 and Figure 4 shown, the wheel set 7 includes wheels 15, wheel axles 16, bearings 17 and wheel seats 18. The wheel axles 16 pass through the wheels 15 and both ends thereof are assembled on the wheel seats 18 through the bearings 17. The top of the wheel seat 18 is connected with the disc spring holder 4 through the connecting bolt 6, and the bottom end abuts against the wheel set auxiliary support 1.

[0039] like Figure 1 As shown, the wheel set auxiliary support members 1 are located on both sides of the rail 9 to keep the wheel set 7 stable.

[0040] In order to better understand the present invention, the following is a complete description of the working principle of the present invention:

[0041] Disc spring wheel assembly installation steps:

[0042] Step 1: Before assembling the wheel, prepare all the assembly parts. Figure 2 As shown, the disc spring 5 is placed on the workbench 20 and pressed by the pressure head 19 to perform compression and force measurement tests on the disc spring 5. The disc spring 5 meets the compression and force measurement value requirements.

[0043] Step 2: If Figure 3 As shown, when the door body 2 is assembled, the track center line is marked and the track 9 is installed. The door body 2 is supported and fixed by the door body support fixture, and then the center line of the retaining seat mounting hole 10 and the center line of the track 9 are re-measured.

[0044] Step 3: If Figure 4 As shown, before installing the wheel set 7, check the installation height of the wheel set 7, assemble and debug the assembled wheel set 7, add lubricating oil to the bearings, and then perform a no-load running test.

[0045] Step 4: If Figure 5 As shown, the assembled disc spring and disc spring retainer 4 are installed on the door body 2 and tightened with the tension bolts 3 to a height that meets the positioning size of the wheel set 7.

[0046] Step 5: If Figure 1 As shown, an auxiliary movable wheel assembly auxiliary support 1 is provided to maintain the stability of the wheel assembly 7. Then the wheel assembly 7 is pushed into the installation position along the track 9, and the connecting bolts 6 between the wheel assembly 7 and the disc spring retaining seat 4 are connected. After the connecting bolts 6 are passed through, the tensioning bolts 3 can be appropriately loosened. Finally, the tensioning bolts 3 are loosened, and the door support fixture and the wheel assembly auxiliary support 1 are removed. The installation of the wheel assembly 7 is completed.

[0047] Installation process:

[0048] Assembly preparation → Disc spring compression and force test → Mark the track center line and install the track (door body has been assembled) → Remeasure the center line of the wheel assembly installation hole and the track center line (door body has been assembled and firmly supported) → Remeasure the wheel assembly installation height → Assemble the wheel assembly (lubricate the bearings and perform a no-load running test) → Assemble the disc spring and disc spring retainer → Tighten the disc spring (tighten the bolts, the height meets the wheel assembly installation size) → Assemble the wheel assembly auxiliary support (movable support to keep the wheel assembly stable) → Push the wheel assembly into the installation position (push it in along the track) → Connect the connecting bolts between the wheel and the disc spring retainer (after the bolts are passed through, the tightening bolts can be loosened appropriately) → Loosen the tightening bolts → Remove the door body fixing device and the wheel assembly auxiliary support → Wheel assembly is completed.

[0049] The above is a detailed description of the implementation methods of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalents or substitutions are all included in the scope defined by the claims of the present invention.
