and 3, step 3: starting the electric telescopic rod 21 to enable the electric telescopic rod 21 to extend to drive the chassis to ascend, enabling the chassis to ascend to drive the arc-shaped sliding block 24 to move upwards through the connecting frame 23, enabling the arc-shaped sliding block 24 to drive the second wheel 11 to move upwards, enabling the limiting block 17 to be clamped into the limiting groove 18 located below, and enabling the first wheel 3 to be in contact with the ground, the second wheel 11 to ascend and not to be in contact with the ground;
and 4, step 4: when the first wheel 3 rolls, the ground grabbing claw 9 is driven to extend out of the avoidance groove 10 at the lowest point, so that the ground grabbing claw 9 acts on the ground to increase the ground grabbing force of the first wheel 3, and the ground grabbing claw 9 tightens the inner part of the first wheel 3 at other positions of the first wheel 3.
The working principle is as follows: when the prefabricated component transfer device works, roads around a house are hollow and have a large amount of soil around the house during house construction in the prior art, and the road surface around the house is muddy in heavy rain, while wheels of the existing transfer device for prefabricated components can slip when the transfer device meets the muddy road, so that the transfer device turns on the side and the transportation of the prefabricated components is influenced, the technical scheme solves the problems that a constructor places the prefabricated components on the top of a frame 1, pushes the frame 1 to transport the prefabricated components, drives the prefabricated components to move by second wheels 11, manually pushes a limiting block 17 to slide into a first sliding groove 15 to stop a first sliding block 14 when the road meets the heavy rain, then starts an electric telescopic rod 21 to pull a connecting plate 20 to move upwards, the connecting plate 20 can drive one end of the expansion plate 19 to move upwards to enable the expansion plate 19 to incline, a chassis of the vehicle frame 1 can be lifted, the situation that the vehicle frame 1 cannot move when the chassis is sunk into a marsh can be avoided, the connecting plate 20 can drive the connecting frame 23 and the arc-shaped sliding block 24 to move upwards together, the arc-shaped sliding block 24 can drive the second wheel 11 to move upwards to enable the first sliding block 14 to relatively slide downwards in the first mounting groove 12 until the limiting block 17 is inserted into the limiting groove 18 positioned below under the action of the first spring 16, at the moment, the second wheel 11 is suspended, the first wheel 3 is contacted with the ground, the vehicle frame 1 is driven by the first wheel 3 to move, when the first wheel 3 rolls, the first wheel 3 drives a plurality of ground grabbing claws 9 which are hinged with the first wheel and arranged along the inner circle array of the first wheel to rotate together, the plurality of ground grabbing claws 9 drive the circular rotating disc 6 to rotate around the eccentric rotating disc 5 with fixed position through the second connecting rod 8, therefore, when the first wheel 3 rolls, the crank-link motion is performed between each group of the first connecting rod 7 and the second connecting rod 8, when the first connecting rod 7 and the second connecting rod 8 are close to the bottom surface, the included angle between the first connecting rod 7 and the second connecting rod 8 is the smallest, and at the moment, the ground-grabbing claws 9 fixed on the second connecting rod 8 can extend out of the avoiding grooves 10, so that when the first wheel 3 rolls, the ground-grabbing claws 9 on each group of the second connecting rods 8 can sequentially extend out of the avoiding grooves 10 and then penetrate into the ground, the ground-grabbing claws 9 penetrating into the ground can increase the ground-grabbing force between the first wheel 3 and a muddy road surface, the ground-grabbing capacity when the first wheel 3 rolls is ensured, the situation that the prefabricated component is laterally turned over due to the slippage of the first wheel 3 on the muddy road is prevented, in addition, the ground-grabbing claws 9 at the top of the first wheel 3 are always accommodated in the first wheel 3, and the accidental injury caused by the fact that constructors touch the sharp surface of the ground-grabbing claws 9 is avoided, the invention ensures the stability of the prefabricated part in the transportation process and does not bring danger to constructors.
