Description

Pile frame and its installation method

The present invention relates to a pile frame and, more particularly, to a pile frame which can be raised and lowered by itself without an auxiliary facility other than the equipment itself. The present invention also relates to a pile frame, will be.

The pile frame is an indispensable mechanical equipment for the construction of the foundation, and all mechanical equipments such as pile hammers, pile hammer, drilling machine, etc. should be hanged and installed on the pile frame; When the pile frame is classified as traveling type, it is mainly divided into two types; a walking pile frame and a caterpillar pile frame; However, for any type of pile frame, its structure typically consists of a chassis, a body, a column, an inclined support and a power system; In case of moving the work place to a long distance because of the relatively long pillar and sloped pillar of the pile frame, it is possible to transport after separating and dismantling the pillar and sloped pillar. After arriving at the new place, You can not use it until you re-install and re-install it; Therefore, the dismantling, installation, erecting and lowering of columns and sloped columns of the pile frame is an important part of the process of using the pile frame.

Currently known methods of such pile frames and laying down and laying down are mainly the following:

Type pile frame, for example a caterpillar pile frame as disclosed in Chapter 5 of the < pile working machine >, published by MECHANICAL INDUSTRIAL CO., LTD. The sloping struts (4 ') must be lowered and separated and transported separately, and after arriving at a new location, they should be reinstalled and erected; The disadvantages of this type 1 pile frame are that the crane and the hoist must be engaged simultaneously in the lowering and erecting work, the auxiliary work equipment is complex, the work difficulty is high, the efficiency is low and the cost is high; The advantage is that the distance H between the supporting points of the inclined support 4 'of the pile frame on the body 2' and the distance L from the supporting point to the support 3 'are both very wide and the support point is in direct contact with the ground And the height position Y is low (see Figs. 1 and 2), so that the stability of the entire equipment and the work safety are excellent.

Type 2 pile frame. The pile frame is mainly composed of a chassis 1 ', a main body 2', a column 3 ', and a retractable hydraulic cylinder 3', which are mainly equipped with a caterpillar traveling device. The pile frame according to the technical idea of the pile frame disclosed in Patent Literature 201510021701.8 Shaped frame 5a ', and a lifting hydraulic cylinder 5b'; One end of the inclined support 4 'is hinged to the column 3' and one end of the 'I'-shaped frame 5a' and the lifting hydraulic cylinder 5b 'are hinged to the body 2'; One end of the three elements of the inclined support 4 ', the' 1 'shaped frame 5a' and the lifting hydraulic cylinder 5b 'is hinged to one place and proceeds to raise and lower using the expansion and contraction operation of the hydraulic cylinder; The advantage of such a pile frame is that it does not require ancillary equipment such as a crane and a hoist to be engaged in the work and can be raised and lowered without a complex auxiliary work device, simple operation and reduced manpower, power and time; The disadvantage of this however is that the distance Ha between the supports of the inclined supports 4 'on the body 2' and the distance La from the supports to the supports 3 ' The height position Ya of the support point is higher than the height position Y of the first type pile frame and is farther away from the support of the ground surface (Figs. 1, 2, 3, 4), the stability of the entire plant is significantly lower than that of the first-type pile frame.

It is an object of the present invention to provide a pile frame and a method of using and installing the pile frame so that a large pile frame can easily and easily be built up and laid down and the entire pile frame can be transported without disassembling the pillar and the inclined pillar, To ensure the rationality of the supporting structure of the column, thereby lowering the cost of use, increasing the working efficiency, and enhancing the stability and safety of the entire facility.

The object of the present invention is achieved through the following technical solutions:

The pile frame includes a movable chassis, a body, a column, an inclined support and a &quot; person &quot; bracket.

The movement of the movable chassis may be a walking type or a caterpillar type; The body is provided with a front support bracket, a front support leg, a middle hinge support, a retractable rear support leg, a cockpit and a power system; Wherein the column is composed of a lower column and an upper column, the column is provided with a guide rail and a sliding device, a lower column is further provided with a suspension, and a lower end of the column is hinged to a front support bracket on the body; The sliding device can freely slide in the guide rails of the columns and can be hingedly connected to the columns by shaft pins, respectively; The inclined post is constituted by a stretching device and a stretching and hydraulic cylinder connected to both ends of the support bar and the support bar, one end of the inclined post is hinged to the sliding device of the post and the other end is hinged to the ' So that the column has a three-point supporting state; Type frame and the lifting hydraulic cylinder are integrally hinged to each other and the 'hinge connection point' portion of the 'I' -shaped frame and the lifting hydraulic cylinder is connected to the intermediate hinge support of the main body by the shaft pin Type frame and the other end of the lifting hydraulic cylinder are hinged to the front and rear portions of the body, respectively.

The pile frame further includes one protruding connector on the cylinder body of the elongated and contracted hydraulic cylinder of the inclined post, and one movable connecting member is hingedly connected to the extensible rod of the elongated and contracted hydraulic cylinder of the inclined post, The first intermediate linking member and the second intermediate linking member forming one set are further provided on the 'one' shaped frame, and the fixed linking member constituting one set is further provided on the rear support legs which are vertically and horizontally expandable and contractible The extension hydraulic cylinder of the inclined post can be hinged to the second intermediate connecting member of the 'one' type frame by the projecting connector and the shaft pin; The movable connecting member on the stretching rod of the stretchable hydraulic cylinder of the inclined support can be connected and fixed on the first intermediate connecting member of the 'one-shaped' frame by the shaft pin, As shown in Fig.

The method of using and installing the pile frame includes the following steps:
