Problems solved by technology
[0003] like figure 1 As shown, it is the structural form of the hoist mechanism brake in the prior art. The brake plate 1' of the hoist mechanism brake is directly installed on both sides of the fixed base through bolts. The disadvantage of this brake is: due to the existence of assembly errors, It cannot be guaranteed that the gap between the hoist wheel side 2' and the brake pads 1' on both sides is completely equal. When the hoist mechanism is running at high speed, there will be a problem of eccentric wear on the brake pad 1' on one side
This will affect the braking effect, reduce the smoothness of braking, and the replacement cycle of the brake pads is short, and the maintenance cost is high

The invention relates to a brake device for a hoisting mechanism and a dynamic compactor. The brake device comprises a brake and an adjusting device. The brake is arranged on the adjusting device. The adjusting device is arranged on a vehicle body. The brake comprises brake pads. The brake pads are arranged at two sides of a hoisting wheel rim of the hoisting mechanism. In the brake state, the brake pads move to the hoisting wheel rim and apply contact forces to realize brake, and the distances between the two sides of the hoisting wheel rim and the brake pads at the corresponding sides are adjusted by the adjusting device. The problem that the hoisting wheel rim of the hoisting mechanism and the brake pads of the brake are eccentrically worn is solved.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a hoisting mechanism braking device and a dynamic compaction machine. Background technique [0002] Dynamic tamping machines are widely used in foundation treatment at present, and its hoisting mechanism is one of the most frequently used mechanisms in the lifting equipment of dynamic tamping machines. Therefore, the reliability and durability of the hoist mechanism brake are particularly important. After the dynamic tamping machine raises the rammer to a specified height, release the rammer to make it fall freely. During the free fall process of the rammer, the winch of the dynamic tamping machine rotates at high speed. In the actual design, there is only a few millimeters gap between the side of the winch wheel and the brake pads on both sides, which requires high installation accuracy. A slight error in installation will result in unequal gaps between the side of the ho...
