Technical Field
[0001] The utility model relates to the technical field of pile drivers, in particular to a mobile pile driver structure. Background Art
[0002] In the pile foundation construction of high-rise buildings, pile drivers are a common type of mechanical equipment for foundation construction. They can mainly press prefabricated piles into the soil by static or dynamic means to form pile foundations. At the same time, the pile driver supports a crawler-type mobile walking structure design, which enables the pile driver to move flexibly on various construction sites and quickly take position to adapt to different construction environments.
[0003] However, after the existing pile driver structure is flexibly moved to the construction site by utilizing the crawler walking mechanism for subsequent pile foundation construction, the pile driver is prone to strong shaking and vibration due to the soil squeezing effect when working. At this time, the crawler walking mechanism without fixing measures is prone to synchronous shaking and is not conducive to providing stable support to the entire pile driver so that it can carry out pile driving operations normally. Therefore, a mobile pile driver structure is proposed to address the above problems. Utility Model Content

[0020] like Figure 1 and Figure 2 As shown, pulley bodies 5 are respectively provided at the front and rear ends of the bottom of the walking drive bottom frame 4, and the pulley bodies 5 are symmetrically arranged in two rows in front and back. The outer part of the pulley body 5 is meshed and connected with a moving crawler body 6. When the driving device drives the two rows of pulley bodies 5 to rotate, it will bring relative transmission force to the moving crawler body 6, so that the equipment can be flexibly moved through the crawler walking structure composed of the pulley body 5 and the moving crawler body 6; the limiting legs 7 are arranged in an inclined structure, and the limiting legs 7 are arranged in two groups of two. The setting of the inclined structure of the limiting legs 7 will make the force points of the fixed structure more balanced and stable; a telescopic cylinder 11 is provided on the upper inner side of the limiting sleeve 8, and the driving end of the telescopic cylinder 11 is electrically connected to the telescopic controller 9, and the movable end of the telescopic cylinder 11 is connected to the limiting slider 10.
