Description
The present invention relates to a kind of piling machinery, is a kind of wheeled electronic stake machine specifically.
Background technology
The stake machine be building trade pile foundation and Base Consolidation Engineering must use equipment.Present stake machine has two characteristics: one heavy two is expensive.The consumption maximum also is the lightest and the handiest small-sized walking stake machine on the building site now, and weight also has about 20 tons.Because heavy, the stake machine is many seldom to be adopted wheeled with crawler type or walking.Because expensive, the rural migrant worker that concrete operations are used cannot afford again.The rural migrant worker is the colony of building trade practitioner maximum now, they require to design selling price stake machine low, that make them might provide a loan and raise funds to afford, do not have the tool of production can only betray labour's situation merely thereby break away from, this is a reasonable request that worth engineers and technicians make great efforts.
Reduce sale price and at first should reduce manufacturing cost.Can be from following several starting with:
One, loss of weight.Use steel less.
The stake machine is made up of other parts of steel construction piece and standard.The overwhelming majority that accounts for its weight is a steel construction piece.Weight reduction is few can be reduced naturally with steel product cost.Except Static pressure pile driver, be used for the stake machine of drilled pile and driven pile in the stake machine, the stability when construction ability and work does not have direct relation with stake machine weight.Centripetal force when boring long threaded hole is irrelevant with stake machine other parts weight from the deadweight of drilling tool and unit head, and the stability during its operation depends on machine ground connection size rather than weight.Analyze us through this and just might alleviate its weight not influencing under the situation of machine function.The first-selected column of loss of weight, secondly platform.Apparatus for work all hangs on the column, and column one alleviates the condition that all there has been loss of weight on the other parts of a machine such as counterweight, platform, chassis.Conscientious column and platform are done the mechanical structure analysis, and loss of weight fully may.
Two, adopt running on wheels.
The manufacturing cost of running gear system also is lower than walking well below crawler type.Its weight approximately is 1/10 of the used ship shape guide rail of walking weight well below walking.And the flexible property of walking helps improving efficiency of construction well.Adopt many group wheels to reduce grounding pressure about 5 tons again if a stake machine loss of weight 3/4 of 20 tons heavy promptly can be reduced to, adopting not only light and handy cost flexibly but also low running on wheels so is optimal selection.The running gear system cost only is the 1/3-1/2 of walking ship shape guide rail.
Three, replace high price outsourcing standarized component with the low manufactured parts of the simple cost of function same structure.
Some parts is wasted one's talent on a petty job on the stake machine, for example pivoting support.The stake machine has been selected for use and the identical pivoting support of excavator crane, but when work must frequent use as the excavator crane, fully can the otherwise designed function, structure and the apt substitute of cost.
By above-mentioned three aspect effort, we have designed cheap practicality and high efficiency
The stake machine has also been applied for patent.But this technical scheme finds to still have the leeway that reduces cost by a relatively large margin when concrete structure designs: at first the stake machine platform also can be made trussed construction and loss of weight, and next adopts the load-bearing of rear wheel drive front-wheel can save a cover drive unit and can make the axle bearing designs simplification.These two improvement can make a machine weight further reduce cost further to reduce.Though reduced the speed of travel slightly but make new departure more meet the requirement of rural migrant worker user because of the raising of cost performance to stake machine low price.
Summary of the invention
The technical problem that we will solve is: design a kind of in light weight, cost is low, stable stake machine when walking and operation, weight require to be relieved to its have identical construction ability walking stake machine about 1/4, adopt running on wheels, the length of its ground connection size and wide (being wheelbase and wheelspan) must not be less than walking and crawler types.
The method that we solve the problems of the technologies described above is: design a kind of wheeled electronic stake machine, it is provided with column, stake machine platform, pivoting support, front and back supporting leg and running gear, it is characterized in that: column and stake machine platform are trussed construction, column is that one side adds diagonal brace for behind the steel plate, steel plate, its excess-three face is the rectangle trussed construction that angle steel is welded into, the stake machine platform is the trussed construction that front end and column rotating shaft frame fuse, pivoting support rotates by the oil cylinder push-and-pull, running gear system is made up of rigidity driving wheel and some groups of BOGEY WHEELs, is rigidly connected with the stake machine.
Introduce the design feature and the operating principle of this wheeled electronic stake machine below by accompanying drawing.

The specific embodiment
Earlier in conjunction with the accompanying drawings, introduce key structure of the present invention and operating principle.
Fig. 4. column truss type cross section structure of the present invention.But the cross section is squarely also.Unique distinction is that four faces of column are that its excess-three face of steel plate is an angle steel simultaneously wherein, have behind the steel plate along the diagonal brace of cross section diagonal.Angle steel should select unequal angle and will grow the external surface that the limit places stressed maximum.Two channel-section steels are welded in the steel plate both sides as the column slideway.The four sides is compared with the column of steel plate weldering entirely on the column that diagonal brace arranged behind this steel plate steel plate and the existing various stake machines, weight saving half and the bending resistance torsional strength is close.
Fig. 5. roller type pivoting support structure.The pivoting support that replaces braking motor (or hydraulic motor) and the rotation of large speed ratio rotary reducer with oil cylinder has two kinds of structures, and a kind of is that oil cylinder rotates no tooth-like pivoting support, this part cost can be reduced half.The another kind of roller type pivoting support of promptly herein introducing.As shown in the figure: raceway is that two blocks of circular steel plates are welded on the car beam 8 with a steel pipe is continuous, and the bolt of strengthening bonding strength between steel plate is arranged behind the steel pipe.Roller is that steel pipe seated 18 is fixed on the machine platform 9 on the steel axle sleeve.Oil cylinder 21 rotates the stake machine platform by pivoted arm 20 rotating shafts 19, and operating principle is turned a millstone similar to south with lever.This roller type pivoting support cost only is 1/5 of outsourcing standard component total price.
Fig. 6. driving device structure schematic diagram of the present invention.Motor 22 drives rigid wheel by reducer 23 and chain (or belt) 24 and rotates, and drives the walking of stake machine.Motor should be selected braking motor for use or add brake in addition on reducer.This driving wheel generally is installed in the back wheel location.
Fig. 7. BOGEY WHEEL structural representation of the present invention.This structure can add Long Wheelbase makes a machine walking stable.BOGEY WHEEL also can be installed many groups to reduce grounding pressure.
Adopting a rigid wheel and a stake machine to be rigidly connected and run trace is a broken line, prop supporting leg when turning to oil cylinder push-and-pull rotation car beam 9 and turn to, is the unique distinction of running on wheels of the present invention.The mobility of running on wheels is far above walking, and efficiency of construction will improve a lot.
How does the present invention work?
After the present invention transported to the building site, supporting leg played frame before and after propping.Install and fix bearing diagonal 3 and adjust length after playing frame.Installation exercise device 15 grades make a machine become duty shown in Figure 1.The hand-held wired remote control of stake machine driver is handled driving wheel makes it arrive the construction stake position.Adjust the column verticality by the front and back hydraulic leg.Get final product bore operation then.
Technique scheme is reduced to stake machine weight and cost very low.Valency is expensive can sacrifice some machine functions more slightly as still disliking: being linked back to change to support also need not unite two into one stake machine platform and Che Liang, directly running gear system is loaded on a machine platform, becomes a kind of " the wheeled electronic stake machine of simple type ".Price can be lower.This moment, the rear wheel drive front-wheel added steering mechanism.When small pile machine very light in weight, rigid wheel can be changed into common rubber tyre.Can draw haul when the advantage that adopts rubber tyre is transportation and reduce freight.
Because column all adopts trussed construction with the stake machine platform, the lighter rolled steel dosage of wheeled stake machine weight still less.Owing to adopt the broken-line type walking manner, the mode that its speed of travel turns to automatically a little less than continuous walking in the patent application of electric wheeled stake machine.But, and, cost is improved because of reducing cost performance because of the wheel train structure simplification makes a machine more firm reliable.Rural migrant worker user at first is to afford to the requirement of stake machine according to investigations, and it satisfies this requirement possibly to the greatest extent in the present invention.Through above-mentioned technological improvement, one has the present invention's " wheeled electronic stake machine " of identical construction ability with 20 tons the walking stake facility of weighing, only 5 tons of gross weights, and manufacturing cost reduces half, and mobility is better so efficiency of construction is higher.This stake machine is highly suitable for the CFG stake, rams the stake of expansion lime-ash, lime soil pile and preformed pile and draws the hole, and engineerings such as deep layer stirring are used.Both energy-conservation, not waste discharge gas is not sent out noise and is helped environmental protection again.Alleviating that a machine weight cuts down the consumption of energy also is a conservation measures.
