Detailed Implementation

[0027] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0028] Example 1

[0029] like Figure 1 As shown, an adjustable support force buffer device for transportation is composed of a support 1, a guide assembly 2, a base 3, a first anti-loosening nut 4, a cylinder 5, a disc spring assembly 6, an adjusting screw 7, a second anti-loosening nut 8, and a partition 9.

[0030] like Figures 2-12 As shown, the support 1 consists of a horizontal slider 17, a bracket 18, and a buffer pad 19; the guide assembly 2 consists of a support rod 13, a guide cylinder 14, a mounting plate 15, and a horizontal guide rail 16, all of which are connected by bolts; the base 3 consists of a nut flange 10, a base plate 11, and a guide rod 12, all of which are connected by bolts.

[0031] Specifically, the support 1 is mounted on the transverse guide rail 16 of the guide assembly 2 via a transverse slider 17, and the support 1 can slide left and right along the transverse guide rail 16; the guide assembly 2 is placed on the guide rod 12 of the base 3 via four guide cylinders 14, and the support rod 13 is installed inside the cylinder 5, pressing against the disc spring assembly 6. When the support 1 shakes up and down with the equipment during transportation, the disc spring assembly 6 transmits the force to the support 1 through the support rod 13, thereby achieving shock absorption and buffering during equipment transportation; the base 3 is mounted on the threaded section of the cylinder 5 via a nut flange 10, and is further secured by a first anti-loosening nut 4; the adjusting screw 7 is screwed into the cylinder 5, and the buffering force of the disc spring assembly 6 on the support rod 13 can be adjusted by adjusting the screw length of the screw 7.

[0032] Furthermore, the partition 9 is installed between the disc spring assemblies 6.

[0033] The support 1 can slide slightly left and right on the transverse guide rail 16 of the guide assembly 2, following the supported equipment.

[0034] Preferably, the support 1 and guide assembly 2 can sway up and down with the equipment during transportation under the action of the disc spring assembly 6. When swaying up and down, the disc spring assembly 6 provides support and cushioning, and the guide rod 12 and guide cylinder 14 provide guidance.

[0035] Preferably, by rotating the cylinder 5, the position of the cylinder 5 relative to the base 3 can be adjusted, thereby adjusting the initial position of the support 1.

[0036] Furthermore, by rotating the adjusting screw 7, the compression of the disc spring assembly 6 can be adjusted, thereby adjusting the supporting force generated by the disc spring assembly 6.

[0037] Example 2

[0038] This device can act as a buffer during equipment transportation. The specific working process is as follows:

[0039] ① By rotating the cylinder 5, the position of the cylinder 5 relative to the base 3 can be adjusted, thereby adjusting the initial position of the support 1;

[0040] ② By rotating the adjusting screw 7, the compression of the disc spring assembly 6 is adjusted, and the buffer device is adjusted to the required support force;

[0041] ③ Install the buffer device base 3 on the transport vehicle, and place it at the bottom of the part of the equipment that needs to be buffered;

[0042] ④ Slide the support 1 left and right until it is in the center position;

[0043] ⑤ The equipment needs to be cushioned and contacted with the support 1 and pressed down. The supporting force provided by the cushioning device gradually increases until the equipment is installed in place. This is the initial position of the cushioning device. During subsequent transportation, the equipment shakes up and down, and the cushioning device shakes up and down with it, providing a changing supporting force to reduce the downward overload on the equipment during transportation.
