Pile frame lifting operation mechanism

Abstract

The invention discloses a pile frame lifting operation mechanism which comprises a hoisting machine group, a vertical column, a top pulley yoke, an operating suspension cage, a hoisting machine over-hoisting limiter, a hoisting machine over-releasing limiter, a wire rope, stop dogs and a speed control system. The vertical column is provided with a pair of side guide rails and rib plates distributed at equal intervals; the operating suspension cage is arranged on the side guide rails; a suspension cage body is hinged with a frame; an angling cylinder is respectively connected with the suspension cage body and the frame; the hoisting machine over-hoisting limiter and the hoisting machine over-releasing limiter are respectively installed in proper positions of lower parts of the top pulley yoke and the vertical column; the wire rope is connected with a hoisting frame; the hoisting frame adopts a rod piece, is installed at the upper part of the frame through a hinge pin and can rotate around the hinge pin; a spring connected with the frame is arranged at the lower end part of the hoisting frame; a throttle valve is arranged in the speed control system; and the stop dogs are symmetrically distributed in proper positions at lower parts of the side guide rails. The pile frame lifting operation mechanism ensures that the operating suspension cage is lifted and rotates along the side guide rails of the vertical column, is convenient to operate, stable and reliable, is convenient to mount and dismount, and guarantees the safety of operating personnel.

Description

technical field

[0001] The invention relates to a lifting operation mechanism, in particular to a pile frame lifting operation mechanism. Background technique

[0002] In modern pile foundation construction, the pile frame is generally used as the working machine, and various construction equipment such as multi-axis drilling machines, long auger drilling machines, vibratory hammers, diesel hammers and hydraulic hammers are installed on the columns to carry out underground construction. Pile foundation engineering construction can meet various pile foundation construction needs such as underground diaphragm wall, on-site mixing pile, compacted sand pile and prefabricated pile. In recent years, as the depth of underground pile foundations has become higher and higher, the height of the pillars of the pile frame has also continued to increase, generally above 30 meters. At present, the maximum height of the pillars of the largest walking pile frame in China has reached 60 mete...
