Hoisting and starting double-acting hammer frame and its barrel diesel piling hammer

Abstract

The invention discloses a hammer carrier with double functions of hoisting and starting-up. The hammer carrier comprises an inner undercarriage; the inner undercarriage is supported by an inner slide track in a sliding manner; the inner slide track is arranged on the hammer carrier body; an outer slide track is further arranged on the hammer carrier body; an outer undercarriage is supported on the outer slide track in a sliding manner; the inner slide track and the outer slide track on the hammer carrier body are parallel to each other; an upper arm strut used for supporting a piston crane hook is arranged below the inner undercarriage; a lower arm strut used for supporting and hoisting the crane hook is arranged on the side surface of the outer undercarriage; both the upper arm strut and the lower arm strut are hinged to a connection lever; the connection lever is hinged to the hammer carrier body. The invention further discloses a barrel-shaped diesel pile hammer comprising the hammer carrier with the double functions of hoisting and starting-up. The hammer carrier and the barrel-shaped diesel pile hammer thereof are simple in structures, and are safe and reliable in operation; the hammer carrier is especially suitable for construction of a maritime pile foundation project.

Description

technical field [0001] The invention relates to a barrel type diesel piling hammer used for offshore pile foundation engineering construction, in particular to a hammer frame for lifting, hoisting and starting the barrel type diesel piling hammer, and a barrel type diesel piling hammer with the hammer frame. Background technique [0002] Pile foundation construction is a very important part of marine engineering. For example, large-scale projects such as offshore oil drilling platforms, wind power generation facilities, deep-water port terminals, cross-sea bridges and cross-river railways all start with the construction of pile foundation projects. In the construction of offshore pile foundations, not only the diameter, depth and bearing capacity of the pile foundations used are far higher than those of land pile foundations, but the energy level and tonnage of construction equipment are often larger, and the construction environment of offshore pile foundations is harsh, and...

AI Technical Summary

Problems solved by technology

Since the two sets of winches perform their own duties, special attention must be paid to the coordination of hoisting and starting and parking actions in actual operations, which brings great inconvenience to the operation of the two sets of winches; The probability of collision, interference, or even entanglement of steel wire ropes will affect the normal operation of the barrel piling hammer in the slightest, and cause safety accidents in the severest case.

The structure of this offshore barrel-type piling hammer with two sets of winches is also very complicated, and the purchase cost and operation cost are large.
