Crawler-type pile frame and method for mounting same

Abstract

The invention discloses a crawler-type pile frame for suspending and mounting pile drivers, drilling machines and other foundation construction machines and a method for mounting the same. The crawler-type pile frame mainly comprises a chassis provided with a crawler travelling device, a frame body, an upright post, a tilted support and a hydraulic power system, wherein one internal combustion engine for driving one set of hydraulic pump units, and two internal combustion engines of the power system can be used for respectively driving two sets of hydraulic pump units, thus supplying enough power for the power system itself and a carrying device. Accordingly, the power can be supplied in a centralized or separate way, thus ensuring high efficiency and saving the energy; the crawler chassis has a more reasonable structure, thus improving the stability of the entire pile frame in travelling and operating; and the upright post and the tilted support of the pile frame are vertically mounted, so the pile frame is simple, convenient, safe and reliable.

Description

technical field [0001] The invention relates to a crawler-type pile frame capable of suspending and installing pile drivers, drilling machines and other foundation construction machines, and also relates to a method for installing the crawler-type pile frame. Background technique [0002] The pile frame is an indispensable mechanical equipment in building foundation construction. Various foundation construction machines such as pile drivers and drilling machines must be suspended and installed on the pile frame for construction; crawler pile frames are all kinds of pile frames. One of them, it uses crawler walking to move its position, which is flexible and convenient, so it is widely used in building foundation construction. The crawler pile frame is mainly composed of a chassis including a crawler traveling device, a fuselage, a column, a diagonal support, and a power system. According to different power driving methods, it is mainly divided into two types: hydraulic craw...

AI Technical Summary

Problems solved by technology

[0006] 1. In addition to the power required for the pile frame's own work, the power that can be provided to the working device is limited, especially the power supply for large working devices and hydraulic dual power heads is even more insufficient;

[0007] 2. The use of high-power engines and corresponding hydraulic systems can solve the problem of insufficient power, but when the pile frame and working devices work separately or sequentially, there are problems of energy waste and low efficiency;

[0008] 3. During the erection process of the pile frame column from the horizontal to 90 degrees vertical to the ground, one end of the oblique support rises with the column, and the hydraulic cylinder support at the other end of the oblique support is always in contact with the ground, and increases with the increase of the erection angle of the column. Passively sliding forward on the ground, at this time, it is necessary to properly and slowly shrink the hydraulic cylinder of the oblique support, so that the support can be strongly supported on the ground without pressing it too deep into the ground; but this operation needs to be vertical to the column It is more difficult to match the lifting speed. If it is accidentally contracted too much, it will cause the oblique support to lose the air, and it will slide forward greatly, which will cause a major accident.

[0009] 4. In order to avoid the complexity and danger of the above-mentioned operation process, it is usually possible to directly use a crane to lift the inclined support for installation, but if there are no two cranes participating in the installation at the same time, the problem ③ cannot be completely solved, and most construction sites do not with such conditions

Its disadvantage is: in order to facilitate transportation, the width dimension of the contracted state of the crawlers on both sides must be guaranteed to be ≤ 3300mm, so when the crawlers on both sides expand outward to the maximum size (about 6000mm), the sliding beam 21d and the hollow sliding beam 21c have already Complete disengagement, the actual overlap between the sliding beam 21d and the overhanging beam 21b has a certain limit, and there are still factors of instability in the structure
