Pile machine

Abstract

The invention discloses a pile machine which comprises at least two wire ropes (2) and a deviation correcting device, wherein one end of each wire rope (2) is respectively wound on a winding drum of a corresponding hoisting group (6), and the other end is respectively connected with a lifting ring of a corresponding lifting platform (3) of the pile machine. The deviation correcting device comprises a gradient detection device and a control device, wherein the gradient detection detects the gradient of the lifting platform (3) and sends a detection signal to the control device, and the controldevice receives the detection signal from the gradient detection device and carries out control operation according to the predetermined control strategy; when the gradient of the lifting platform (3) reaches a preset value, the control device adjusts the rotating speed of the winding drum on at least one side of the lifting platform (3) so as to lower the gradient of the lifting platform (3). The deviation correcting device of the pile machine can conveniently and quickly control the swing of the lifting platform in a proper range so as to basically keep the lifting platform in horizontality.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a pile driver. Background technique [0002] With the rapid development of my country's economic construction, the use of construction machinery is becoming more and more extensive. However, some construction machinery has a relatively high height. Once a fault occurs and needs to be repaired, maintenance personnel need to climb to a high place, which is very inconvenient. , it is necessary to use the lifting platform to transport the staff to a high place for maintenance work. [0003] In the prior art, the lifting platform used for construction machinery is generally lifted by the wire rope of the hoisting group and maintained in the suspended state. [0004] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical lifting platform in the prior art. [0005] Such as figure 1 As shown, the lifting platform generally includes a hoist...

Problems solved by technology

[0007] However, during the ascent of the lifting platform 3', due to the different frictional forces of the sliders on both sides, the lifting platform will be tilted; The lifting rings on both sides of the platform 3' are hanging, and the center of gravity of the lifting platform 3' is easy to tilt due to the movement of the staff, which puts the staff in danger
