Description

Pile frame and installation method thereof Technical field

The present invention relates to a pile frame, and more particularly to a pile frame which can be erected by itself without the aid of auxiliary equipment other than the machine. The present invention also relates to a method of installing and installing the pile frame.

Background technique

The pile frame is an indispensable mechanical equipment in the construction of the foundation of the building. All kinds of mechanical equipment such as pile driver, pile hammer and drilling machine are to be hung and installed on the pile frame for construction; when the pile frame is classified by walking mode At the time, it is mainly divided into two types: the walking type pile frame and the crawler type pile frame; however, regardless of the type of pile frame, the structure is generally mainly composed of a chassis, a fuselage, a column, an inclined support and a power system; The diagonal support is long. In the case of long-distance transitions, etc., it is necessary to disassemble and disassemble the column and the oblique support before transporting. After the new site, it is necessary to re-install the column and the oblique support and stand up before entering the state of use. Therefore, the disassembly and installation of the column and the diagonal support of the pile frame and the vertical collapse operation are an important part in the use of the pile frame.

At present, the well-known pile frames and inverted squatting methods are mainly as follows:

The first type of pile frame, such as the crawler type pile frame published in the fifth chapter of "Pile Work Machinery" published by Machinery Industry Press: the pile frame needs to collapse the column 3' and the oblique support 4' during the transition. After disassembly, the vehicle is transported separately, and the new site is reinstalled. The disadvantage is that the crane does not only need the crane and the hoist to participate in the operation at the same time, but also the auxiliary operation device is complicated, the operation is difficult, the efficiency is low, and the cost is high. The advantages are: the distance H between the fulcrum of the pile frame 4' on the fuselage 2' and the distance L from the fulcrum to the column 3' are wide, and the fulcrum is hinged to the rear leg 2d which is in direct contact with the ground. 'Up, and the height position Y is low (see Figure 1, Figure 2), which makes the stability and safety of the whole machine better.

A second pile frame, such as the technical solution of a pile frame disclosed in the patent 201510021701.8: the pile frame mainly comprises: a chassis 1' with a crawler walking device, a fuselage 2', a column 3', and an inclined support with a telescopic cylinder 4 ', a letter frame 5a', a lifting cylinder 5b'; one end of the oblique support 4' is hinged to the column 3', one end of the bracket 5a' and the lifting cylinder 5b' are respectively hinged to the fuselage 2'; The other end of the support 4', the inline frame 5a' and the lifting cylinder 5b' are hinged at one place, and the expansion and collapse of the cylinder are performed by the telescopic movement; the advantage is that the auxiliary equipment such as a crane and a winch is not required to participate. The operation can be carried out without complicated auxiliary working devices, and the operation is simple, saving manpower, material resources and time; but the disadvantages are: the distance Ha of the oblique support 4' between the fulcrums on the fuselage 2', and the fulcrum to The distance La of the column 3' is smaller than the corresponding distances H and L of the first type of pile frame, and the height position Ya of the fulcrum is higher than the height position Y of the first type pile frame, and the support away from the ground ( See Figure 1, Figure 2, Figure 3, Figure 4) to make the stability of the whole machine clear Significantly lower than the first type of pile frame.
