Embodiment Construction

[0027] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] figure 1 Shown is a schematic diagram of the structure of the anti-shock luffing mechanism of an embodiment of the present invention. The anti-shock luffing mechanism of this embodiment includes a tension member whose end is connected to the arm head, and the tension member retracts the arm frame 2 under the action of the driving mechanism 1, so that the arm frame 2 raises and lowers the arm with the hinge point A as the center. arm (reference figure 2 ). The tension member can be an independent part or a combination of several parts.

[0029] exist figure 1 In the shown embodiment, the anti-shock luffing mechanism is a hoist-driven luffing mechanism, including a rope 51, a fixed pul...

Abstract

The invention discloses a dynamic compactor and an anti-impact luffing mechanism thereof. The anti-impact luffing mechanism comprises a tension part and a telescopic linear driving part, the end of the tension part is connected to an arm head, the tension part collects or releases an arm rest under the action of a driving mechanism so that the arm rest lifts or lowers an arm by taking a hinged point as a center, and the tension part is connected with one end or two ends of the linear driving part. When a pounder suspended on the arm rest falls down, the linear driving part extends out or retracts, the tension part releases the arm rest, the arm rest lowers the arm within a preset range, the tension of the tension part can be compensated by the travel of the linear driving part, and violent shaking of the arm rest due to reacting force is avoided. When the pounder is lifted, the linear driving part is reset. The anti-impact luffing mechanism has the advantages of operational stability, high safety, low cost, less modification of an existing structure and the like.

Description

technical field [0001] The invention mainly relates to the field of engineering machinery, in particular to an anti-impact luffing mechanism of a dynamic compaction machine and a dynamic compaction machine including the anti-impact luffing mechanism. Background technique [0002] Dynamic tamping machine is a kind of construction machinery used for impact compaction of materials or foundations, widely used in the construction of industrial and civil buildings, warehouses, yards, docks, airports, road and railway roadbeds, artificial islands, etc. . The luffing mechanism is an important component of the dynamic compaction machine, including a tension member whose end is connected to the arm head, and the tension member retracts the arm frame under the action of the driving mechanism. [0003] The pitch angle of the jib frame of the dynamic compaction machine can be changed through the luffing mechanism, so as to realize the raising and lowering of the boom frame, and then hoi...
