Embodiment Construction

[0023] 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.

[0024] like figure 1 As shown, the present invention provides a dynamic compaction machine, comprising a crawler chassis 100, a slewing support 101, and a platform 102. The slewing support 101 is installed on the crawler chassis 100, and the platform 102 is installed on the slewing support 101. The boom 103 is equipped with a counterweight 105 and an anti-dipping oil cylinder 4 at the rear end of the platform 102 . When lifting the hammer, that is, during the lifting process of the rammer 104, the boom 103 is pulled down by the weight of the rammer 104 to generate a forward tilting force, and the dynamic compactor balances the forward tilting force by the counterweight 105 of the rear seat. Whe...

Abstract

The invention discloses a dynamic compaction machine backward-tilting preventing control method and system. A backward-tilting preventing oil cylinder is installed at the tail of a dynamic compactionmachine, and when the dynamic compaction machine raises a hammer, the backward-tilting preventing oil cylinder is controlled to extend and be supported on the ground; when the backward-tilting preventing oil cylinder extends and is supported on the ground to achieve the preset recoil force, an oil inlet and outlet path of the backward-tilting preventing oil cylinder is controlled to be locked; when the dynamic compaction machine walks or rotates, the backward-tilting preventing oil cylinder is controlled to be drawn back. According to the dynamic compaction machine backward-tilting preventingcontrol method and system, backward tilting impact force of the dynamic compaction machine is reduced, front-back swing of the dynamic compaction machine is reduced, the working stability of the dynamic compaction machine is improved, a rotary support and a rotary platform apparatus of the dynamic compaction machine are prevented from being damaged, and the service life of the rotary support and the service life of the rotary platform apparatus of the dynamic compaction machine are prolonged.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a method and system for controlling back tilting of a dynamic compaction machine. Background technique [0002] The dynamic tamping machine uses the winch to repeatedly lift the rammer vertically, and uses the high impact generated by the high drop of the rammer to compact the foundation. The tamping energy of the dynamic tamping machine = the height of the falling distance × the weight of the tamper, for example: the weight of the tamper is 30T, the height of the falling distance is 15m, and the tamping energy = 30×15=450T.m. The drop height refers to the free fall height of the rammer. The working mode of the dynamic tamping machine includes decoupling mode and non-decoupling mode. The decoupling mode means that the hoisting wire rope of the dynamic ramming machine is connected with a decoupling device. The device releases the rammer (that is, the state of releasing the hammer), the ...
