Description

Electric caterpillar band suspension type stake machine

Technical field

The utility model relates to a kind of piling machinery, is the pile driver of a kind of Motor Drive crawler travel and system stake operation specifically.

Background technology

From the history of stake machine development as can be known: the crawler type pile driver is to be developed by crawler crane.What occur the earliest is suspension type crawler belt pile driver.Its structure is that column lower end is hinged and connected itself and crane with a horizontal support at crawler crane arm of derrick forward mounting one root post.Change the column degree of bending forward and backward by the elevation angle of adjusting arm and promptly adjust the column verticality of a direction backward forward.Column can't be regulated to the right verticality left, can only rely on the planeness on ground to make two crawler belts on a horizontal plane as far as possible.The three fulcrum crawler type pile drivers that occur subsequently at this shortcoming, its column lower end is articulated in the crane front portion with cross axle or diminished shaft, the column upper end adopts two bearing diagonals to be hinged on the formation supported at three point of crane rear portion, the length of regulating two bearing diagonals by oil cylinder changes the angle of inclination in each orientation, front, rear, left and right of column, thereby the verticality ground of column is smooth inadequately also to be fully guaranteed even make.

More than two kinds of pile drivers all be on the basis of traditional crawler crane that is power, to transform to form with the internal combustion engine, the internal-combustion engine drives hydraulic system drives crawler travel and hoist engine operation.After removing the column arm, main frame (or claiming the chassis) should not be dismantled when transportation from the crawler belt to the hoist engine again, is an overall structure.This overall structure has two characteristics: the one, and it is higher that a machine is made the big cost of difficulty, and middle-size and small-size factory is difficult to make production.The 2nd, to be convenient to transport the complete machine size during for the transfer building site and to be restricted, the ground connection size of its crawler belt also is restricted when causing construction operation, and the stability during work is good inadequately.In addition, the construction machinery of fuel oil is subject to the oil price source of goods influence in short supply of rising violently, over-emitting black exhaust but also send out the high-decibel noise not only during construction, and the utmost point is unfavorable for environmental protection.Also be that this stake machine should improvements.

China develops electric caterpillar band stake machine (ZL97233755.5) electric cater-pillar crane (ZL200620167348.0) and multifunctional turn digging dynamoelectric drilling machine (ZL200510043613.4) voluntarily, to break the whole up into parts by the monolithic construction of internal-combustion engine drives hydraulic system driving crawler travel and Working mechanism work, decompose and to be simplified to several separate function subsystem such as crawler travel, hoist engine, auger etc. respectively by different motor-driven, subsystems that these several cheap standard components of being produced by the special manufacturer are fully formed are installed on the working platform again.Thereby the manufacture difficulty and the cost of production of these several engineering machinery have been reduced significantly.It only is with about 1/3 of ICE-powered crawler type stake machine that electric caterpillar band stake mechanism causes this, the existing domestic production that replaces the latter basically.

Existing advantage with ICE-powered suspension type crawler belt pile driver is a dual-use: loading onto column and horizontal brace is a machine; Pulling down the column horizontal brace is exactly crane.Its shortcoming is as previously mentioned: its column can only be bent forward and backward an orientation adjustment verticality, must strict ground grading during operation, otherwise will influence construction quality.Speaking of here, we are easy to expect: electric cater-pillar crane also should be accomplished dual-use.But, install additional the pile driver that repacks into behind column and the horizontal brace should avoid can only an orientation adjustment column verticality shortcoming.For this reason, must take technical measures to make its column possess the function of comprehensive adjustment verticality during repacking.

Summary of the invention

The technical problem of the confidential solution of the utility model electric caterpillar band suspension type stake is: under the prerequisite that does not influence the electric cater-pillar crane original function, repack it into suspension type pile driver by the mode that installs column and horizontal brace additional, the column that requirement is installed additional can comprehensive all around its verticality of adjustment, and requires to reduce as far as possible manufacturing cost.

The scheme that the utility model solves the problems of the technologies described above is: the electric caterpillar band suspension type stake machine that designs a kind of Motor Drive crawler travel and hole drilling and pile making operation, it is provided with column, top pulleys group, horizontal brace and connects column upper end and the electric cater-pillar crane that is connected column lower end by horizontal brace by arm of derrick, it is characterized in that: column lower end is equipped with a hydraulic leg, a hydraulic leg is respectively adorned in the both sides, lifting platform rear end of electric cater-pillar crane, and the counterweight of lifting platform rear end describes that by one or several empty van device constitutes.

The utility model removes column and horizontal brace, just reverts to crawler crane, and original lifting function is not affected.Load onto column and horizontal brace and just become a suspension type crawler pile machine that can pass through three the comprehensive adjustment column of hydraulic leg verticality.

The specific embodiment

We illustrate in conjunction with the accompanying drawings.

As can be seen from Figure 1: the utility model can be regarded as by the two large divisions and constitutes:

First column (comprising 1 column top pulleys group among the figure, 3 columns, 16 column hydraulic legs) and apparatus for work (i.e. 1 auger among the figure, 19. drilling rods, casing at the bottom of 17. drilling rods), and horizontal brace 18.

It two is that column 3 upper ends are suspended on the electric cater-pillar crane that on its arm of derrick 4 column 3 lower ends is connected by horizontal brace 18.

This constituted mode and existing as broad as long with ICE-powered suspension type crawler pile machine.Unique distinction of the present utility model is to Duo three hydraulic legs: 13 among the figure and 16 than existing suspension type crawler pile machine that wherein 16 1 are installed on the column coxopodite bottom, 13 two both sides, rear end that are installed in lifting platform 7 respectively.These three hydraulic legs constitute three fulcrums.Desire to make column to do low-anglely to lean forward or swing back, can extend or shrink two supporting legs of lifting platform rear end; Desire to make column to make the supporting leg on right side, the left-leaning extending lifting platform rear end of low-angle, otherwise elongation left side supporting leg can make column low-angle Right deviation.The cooperation of such three supporting legs constitutes the micro-tensioning system of column verticality, has solved the comprehensive adjustment problem of suspension type crawler pile machine column verticality.

After Fig. 2 represents that the column coxopodite is loaded onto hydraulic leg, when the stake machine plays the frame front column and lies low on ground, the shape of hydraulic leg ground connection.Column is by from the ground pull-up when playing frame, and supporting leg is the connecting axle half-twist on bearing 20.This structure is more stable when having made frame.Pulling down hydraulic leg during the transportation of stake machine is placed on the lifting platform.

Fig. 3 is the distinctive empty van shape of a utility model counter weight construction.This counterweight is that the empty van 12 that several steel sheets are welded into is placed on the counterweight support 21.The counterweight support is made by channel-section steel and is installed on the lifting platform 7.During construction in the empty van on demand weight pack on the building site sandstone material commonly used into as counterweight, construction finish to incline when a stake machine the is withdrawn from the arena building stones that shake out only transport empty van.Can reduce by several tons more than counterweight freight with this, reduce skimble-skamble energy consumption in the counterweight transportation.Alleviating hauled weight is exactly a kind of conservation measures.The manufacturing cost of empty van counterweight also is minimum in the various counterweights.Determine the sandstone loading amount according to required counterweight during use.

In sum, the utility model of dual-use has not only reduced the manufacture difficulty and the cost of production of stake machine significantly, has improved the construction quality of stake machine, and has reduced the cost of transportation when the stake machine shifts the building site.Be that a kind of not oil firing is not smoldered and do not had the energy-saving and emission-reducing of high-decibel noise pollution building machinery.
