As an improvement of the embodiment, as shown in FIG. 1, the upper supporting plate 1 is provided with a mounting groove 1-1, the V-shaped supporting block 3 is inserted into the mounting groove 1-1, the V-shaped groove on the V-shaped supporting block 3 can be tangent with the circular tube beam 8 to fix the circular tube beam 8, the V-shaped supporting block 3 is positioned by means of the mounting groove 1-1 on the table top of the upper supporting plate 1, and is quickly inserted and mounted, and the V-shaped supporting block 3 with different specifications can be removed or replaced and mounted according to the requirements of different vehicle types, so that the operation is quicker.
As an improvement of the embodiment, as shown in fig. 1, two V-shaped supporting blocks 3 are symmetrically installed at two ends of the upper supporting plate 1, so that a circular tube beam 8 installed on the V-shaped supporting blocks 3 can be more stable.
As an improvement of the embodiment, as shown in fig. 1 and 2, two guide mechanisms 4 are symmetrically installed at two ends of the supporting frame bottom plate 7, the lifting adjusting mechanism 5 is installed on the supporting frame bottom plate 7 and is located at the center of the two guide mechanisms 4, and considering the weight of the cross beam of the mining dump truck, when the height of the upper supporting plate 1 is adjusted by the lifting adjusting mechanism 5, the left and right balance of the cross beam is difficult to be ensured by the single lifting adjusting mechanism 5, so that the guide mechanisms 4 are arranged at two sides of the lifting adjusting mechanism 5, and the limiting guide function is achieved.
