Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pile machine production and installation equipment, in particular to a pile machine arm installation alignment device. BACKGROUND

[0002] The pile machine is an important equipment for foundation treatment in civil engineering, and is widely used in complex foundation engineering such as high-rise buildings, bridges and ports. The pile machine is mainly composed of a base, a main arm, a secondary arm and the like. The main arm and the secondary arm, as important components of the pile machine, play a key role in loading and movement. Generally speaking, the production process of the pile machine arm includes design, material selection, cutting, welding, assembly, inspection and the like. In this series of processes, the connection of the main arm and the secondary arm is crucial, which is directly related to the stability of the pile machine arm in the later use process.

[0003] The traditional device has the following disadvantages:

[0004] At present, the connection of the main arm and the secondary arm of the pile machine is usually carried out by manual cooperation with the hoisting of the crane for position alignment. First, the main arm is placed on the installation table or installation rack, then the secondary arm is lifted by the crane and transported above the main arm, then the suspended secondary arm is manually rotated by the worker until the pin holes of the secondary arm and the main arm are aligned, and finally another worker knocks the connecting pin through the pin holes of the main arm and the secondary arm to complete the connection of the pile machine arm. This installation method has some obvious shortcomings. First, the secondary arm is manually rotated by the worker in the state of hoisting by the crane, which is difficult and inefficient due to the large weight of the secondary arm, and the risk coefficient is also large. Secondly, due to the large weight and inertia, the shaking during manual alignment can also cause low accuracy, which can further induce the difficulty of the connecting pin passing through when this problem occurs. Generally, the worker will increase the knocking force to make the connecting pin pass through the pin hole forcibly. Although this method can complete the installation of the connecting pin, it can also cause damage to the pin body and the main arm and secondary arm of the pile machine. SUMMARY

When the trolley places the main arm and the auxiliary arm on the support carriage 302, the positioning pin 606 should be removed first, and the secondary gear 605 should be pulled to the side away from the main gear 603. When the position of the auxiliary arm needs to be fine-tuned, the positioning pin 606 is removed again, and the secondary gear 605 is pushed forward until it is engaged with the main gear 603.
