[0045] Embodiment 1

[0046] See Figures 1-5 As shown, a weight adjustment device provided by an embodiment of the present application includes: a lifting mechanism 2; a bottom plate 1, the bottom plate 1 is rotatably connected below the lifting mechanism 2; a plurality of counterweight plates 4, the counterweight plates 4 are arranged above the bottom plate 1, the counterweight plates 4 are provided with bottom plate through holes 41 for the bottom plate 1 to pass through, when the bottom plate 1 rotates, the whole bottom plate 1 passes through the bottom plate through holes 41, so that the bottom plate 1 is separated from the counterweight plates 4.

[0047] The bottom plate 1 is used to carry the counterweight plates 4, the bottom plate 1 is rotatably connected to the lifting mechanism 2, when it is necessary to change the counterweight, the bottom plate 1 is rotated to a suitable position so that it can pass through the bottom plate through holes 41 on the counterweight plates 4, and under the action of the lifting mechanism 2, it moves to different heights, so that different numbers of counterweight plates 4 can be carried, and then the bottom plate 1 is rotated to a position where it is engaged with the bottom plate through holes 41, realizing the change of the counterweight, which has high flexibility of counterweight.

[0048] See Figures 1-4 As shown, it further includes a driving part 3, the lower end of the driving part 3 is connected to the bottom plate 1, and the upper end of the driving part 3 is connected to the lifting mechanism 2; the bottom plate 1 rotates under the drive of the driving part 3.

[0049] The driving part 3 is arranged to connect the bottom plate 1 and the lifting mechanism 2, and drive the bottom plate 1 to rotate through the driving part 3, so that the bottom plate 1 rotates to a position where it can pass through the bottom plate through holes 41 or is engaged with the bottom plate through holes 41, and the lifting mechanism 2 adjusts the height of the bottom plate, thereby changing the counterweight.

[0050] See Figures 1-4 As shown, the driving part 3 includes:

[0051] A first connecting rod 31, the upper end of the first connecting rod 31 is fixedly connected to the lifting mechanism 2, the lower end of the first connecting rod 31 is rotatably connected with a third gear 35, the bottom plate 1 is fixed on the third gear 35, and the bottom of the lower end of the first connecting rod 31 is fixedly connected with a limiting block 37, the upper end of the limiting block 37 abuts against the bottom plate 1;

[0052] The second connecting rod 32, the first end of the second connecting rod 32 is vertically installed in the middle of the first connecting rod 31, and the second end is successively provided with a second gear 33 and a first gear 34 along the direction away from the first connecting rod 31; both the second gear 33 and the first gear 34 are rotatably connected to the second connecting rod 32, the second gear 33 is fixedly connected to the first gear 34, and the second gear 33 meshes with the third gear 35;

[0060] The support column and the limiting plate play a limiting role on the chute of the rack 36, ensuring that the rack 36 is not easily separated from the lifting column 21 during the sliding process, and ensuring the stability when driving the first gear 34 to rotate.

[0061] See Figures 1-2 As shown, a boss 43 is provided at the bottom of the counterweight plate 4.

[0062] Since a boss 43 is provided at the bottom of the counterweight plate 4, there is a gap with a certain width between adjacent counterweight plates 4, and the bottom plate 1 can rotate within this gap, ensuring that different numbers of counterweight plates 4 can be carried.

[0063] Embodiment 2

[0064] See Figure 6 As shown, an embodiment of the present application provides a counterweight trolley tooling, including a vehicle body 5 with an accommodation space provided therein; a guide post 6, the guide post 6 is arranged inside the vehicle body 5, and the upper and lower ends of the guide post 6 are respectively fixed to the top and bottom of the vehicle body 1; the above-mentioned weight adjustment device, the weight adjustment device is arranged inside the vehicle body 1, and a guide post through hole 42 is also provided on the counterweight plate 4, and the counterweight plate 4 is slidably sleeved on the guide post 6 through the guide post through hole 42.

The top of the lifting mechanism 2 is arranged outside the vehicle body 5, which is convenient for cooperating with devices such as slings to complete the counterweight operation. The side plate of the vehicle body 5 uses a transparent material, enabling the operator to more intuitively see the number of counterweight plates 4 carried.

[0070] The working process of the present utility model is as follows:

[0071] First, determine the counterweight weight according to the vehicle model to be counterweighted, and then determine the target height of the movement of the bottom plate 1 in the weight adjustment device. The driving part 3 rotates the bottom plate 1 so that the bottom plate 1 can pass through the bottom plate through hole 41, and the lifting mechanism 2 moves the bottom plate 1 to the target height. Then the driving part 3 rotates the bottom plate 1 to a position where it is engaged with the bottom plate through hole 41, so that it can carry the corresponding weight of the counterweight plate, completing the change of the counterweight weight.

[0072] Push the counterweight trolley tooling with the adjusted counterweight to the designated position, fix it with the Fuma wheels 51, connect the vehicle to be counterweighted and the top of the lifting mechanism 2 with a sling, and the counterweight is completed. During the counterweight process, the trolley always stays at the designated position. The counterweight plate 4 moves along the guide post 6 inside the trolley. If it is necessary to change the counterweight during use, the number of counterweight plates 4 carried by the bottom plate 1 can be directly adjusted on site, which has the advantages of simple operation, convenience, speed and high flexibility.

[0073] Finally, it should be noted that the embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments.
