[0007] A support assembly, comprising a support plate and a support frame, wherein the support frame is fixedly connected to the center of the upper end of the support plate;

[0008] The rolling assembly includes an electric telescopic rod, a movable plate, a first slide groove, a sliding shaft, a connecting rod, a second slide groove, a support shaft, and a rolling wheel. The electric telescopic rod is fixedly connected to the upper center of the support frame, the movable plate is fixedly connected to the bottom of the electric telescopic rod, the first slide groove is opened at the center of the support plate, the sliding shaft is fixedly connected to both sides of the movable plate, one end of the connecting rod is sleeved on the outer surface of the sliding shaft, the second slide groove is opened at the center of the support plate, the support shaft is sleeved on the other end of the connecting rod, and the rolling wheel is sleeved on the outer surface of the support shaft.

[0009] Furthermore, the support assembly also includes a base frame, and the support plate is fixedly connected to the upper end of the base frame.

[0010] Furthermore, the electric telescopic rod extends downward through the center of the support frame, and the sliding shaft is slidably connected inside the first groove.

[0011] Furthermore, the support shaft is slidably connected to the inside of the second groove, and the rolling roller is located inside the support plate.

[0012] Furthermore, the movable plate is located inside the lower end of the support frame, and the connecting rod is located outside the support plate.

[0013] Furthermore, it also includes an adjustment assembly, which includes a slider, a limiting plate, a movable rod, a top plate, and a fixing nut. The slider is slidably connected to the inside of the first groove, the limiting plate is fixedly connected to the inside of the slider, the movable rod is fixedly connected to the top of the limiting plate, the top plate is fixedly connected to the top of the movable rod, and the fixing nut is threadedly connected to the outer surface of the movable rod.

[0014] Furthermore, the slider is located below the sliding shaft, and the limiting plate is located on both sides of the bottom end of the movable plate.

[0015] Furthermore, the movable rod extends upward through both sides of the movable plate and the support frame, and the outer surface of the movable rod has a threaded structure relative to the fixed nut.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] I. This utility model, by setting up a rolling assembly, uses an electric telescopic rod to extend and retract, which in turn drives a movable rod to move up and down. The movable plate moves up and down, which in turn drives a sliding shaft to move up and down. The sliding shaft drives one end of a connecting rod to move up and down, and the connecting rod then drives a support shaft to move back and forth horizontally. This causes the support shaft to drive the rolling roller to roll back and forth, greatly increasing the rolling efficiency.

[0018] II. Based on the first beneficial effect, by setting up an adjustment component, the top plate is moved, causing the movable rod to move up and down. The movement of the movable rod causes the limiting plate and the slider to move. According to the required rolling gap, the limiting plate moves to the appropriate position. When the limiting plate moves to the appropriate position, the movable rod is fixed to both sides of the support frame by fixing nuts, thereby fixing the limiting plate. The limiting plate can then control the maximum downward movement distance of the movable plate, thereby controlling the maximum outward movement distance of the rolling roller, so as to achieve adjustment of the rolling gap.

[0034] The electric telescopic pole 21 is used to drive the movable plate 22 to move up and down. The movable plate 22 is used to drive the sliding shaft 24 to move up and down. The first slide groove 23 is used to guide the movement of the sliding shaft 24. The sliding shaft 24 is used to drive one end of the connecting rod 25 to move up and down. The connecting rod 25 is used to drive the support shaft 27 to move. The second slide groove 26 is used to guide the movement of the support shaft 27. The support shaft 27 is used to support the rolling roller 28 and drive the rolling roller 28 to move. The rolling roller 28 is used to roll the road.

[0035] The support assembly also includes a base frame 11, with a support plate 12 fixedly connected to the upper end of the base frame 11;

[0036] The base frame 11 is used to support the support plate 12, the support plate 12 is used to support the support shaft 27 and the support frame 13, and the support frame 13 is used to support the electric telescopic rod 21.

[0037] The electric telescopic rod 21 extends downward through the center of the support frame 13, and the sliding shaft 24 is slidably connected inside the first groove 23;

[0038] When the electric telescopic rod 21 extends or retracts, the movable plate 22 moves up and down under the drive of the electric telescopic rod 21, and the movable plate 22 drives the sliding shaft 24 to move up and down.

[0039] The support shaft 27 is slidably connected to the inside of the second groove 26, and the rolling roller 28 is located inside the support plate 12;

[0040] When the support shaft 27 moves horizontally under the drive of the connecting rod 25, the support shaft 27 drives the rolling wheel 28 to roll horizontally, so that the rolling wheel 28 rolls the road.

[0041] The movable plate 22 is located inside the lower end of the support frame 13, and the connecting rod 25 is located outside the support plate 12.

[0042] When the sliding shaft 24 moves up and down, it drives one end of the connecting rod 25 to move up and down. The movement of the connecting rod 25 applies a force to the support shaft 27. The support shaft 27 is limited by the second sliding groove 26, so that the support shaft 27 moves horizontally under the drive of the connecting rod 25.

[0043] Working principle: When road rolling is required, the electric telescopic pole 21 is activated, causing it to extend and retract. The extension and retraction of the electric telescopic pole 21 drives the movable plate 22 to move up and down. The up and down movement of the movable plate 22 drives the sliding shaft 24 to move up and down along the inside of the first sliding groove 23. The movement of the sliding shaft 24 drives one end of the connecting rod 25 to move up and down. The movement of the connecting rod 25 applies a force to the support shaft 27, causing the support shaft 27 to move horizontally along the second sliding groove 26. The movement of the support shaft 27 drives the rolling wheel 28 to roll horizontally, thus simultaneously rolling both sides of the road.

[0044] Example 2

[0045] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0046] The adjustment assembly includes a slider 31, a limiting plate 32, a movable rod 33, a top plate 34, and a fixing nut 35. The slider 31 is slidably connected to the inside of the first slide groove 23, the limiting plate 32 is fixedly connected to the inside of the slider 31, the movable rod 33 is fixedly connected to the top of the limiting plate 32, the top plate 34 is fixedly connected to the top of the movable rod 33, and the fixing nut 35 is threadedly connected to the outer surface of the movable rod 33.

[0047] The slider 31 is used to guide the movement of the limiting plate 32, the limiting plate 32 is used to limit the movable plate 22, the movable rod 33 is used to support the limiting plate 32, the top plate 34 is used to drive the movable rod 33 to move, and the fixing nut 35 is used to fix the movable rod 33 to both sides of the support frame 13.

[0048] The slider 31 is located below the sliding shaft 24, and the limiting plate 32 is located on both sides of the bottom end of the movable plate 22;

[0049] When the limiting plate 32 moves up and down inside the support plate 12, the limiting plate 32 moves vertically up and down along the first slide groove 23 under the drive of the slider 31.

[0050] The movable rod 33 extends upward through both sides of the movable plate 22 and the support frame 13, and the outer surface of the movable rod 33 has a threaded structure relative to the fixed nut 35.

[0051] When the movable rod 33 moves up and down, the movable rod 33 passes through the movable plate 22 and drives the limiting plate 32 to move up and down.

[0052] Working principle: When it is necessary to adjust the rolling gap of the rolling roller 28, the fixing nut 35 is turned so that it does not fix the movable rod 33. Then, a moving force is applied to the top plate 34, causing the top plate 34 to drive the movable rod 33 to move up and down. The movement of the movable rod 33 drives the limiting plate 32 to move. The limiting plate 32 moves vertically up and down along the first slide groove 23 under the drive of the slider 31. When the limiting plate 32 moves to the appropriate position, the fixing nut 35 is turned in the opposite direction to fix the movable rod 33, thereby keeping the position of the limiting plate 32 fixed. At this time, the downward movement of the movable plate 22 will be blocked by the limiting plate 32, thereby limiting the distance that the rolling roller 28 moves outward, thus adjusting the rolling gap of the rolling roller 28.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
