Description
Technical field
The present invention relates to a kind of upper frame for piling machinery, especially a kind of upper frame for rotary drilling rig.
Background technology
The upper frame of the upper frame of piling machinery, especially rotary drilling rig, be connected and support hoist engine with the revolution of the chassis of piling machinery/rotary drilling rig, the framework of hydraulic motor, rotary reducer, driver's cabin, cat ladder, counterweight and swing arm supporting arrangement etc..The quality of its structural behaviour directly decides the quality of piling machinery/rotary drilling rig.
Fig. 1 shows a kind of structure of the upper frame for generally using in the prior art.As shown in the figure, such upper frame includes a upper frame base plate 1 ', two length for extending whole base plate substantially and the longeron 2 ' being parallel to each other are provided with the upper frame base plate 1 ', the front portion of base plate 1 ' or two longerons 2 ' being parallel to each other is provided with swing arm support plate 3 ' etc..The rotary decelerating machine base 4 ' of the rotary reducer being connected with chassis revolution is provided with behind the swing arm support plate 3 '.One hoist engine frame fixed plate 5 ' is set across welding on two longerons 2 ' after rotary reducer, the hoist engine frame 6 ' equipped with hoist engine 7 ' is connected in hoist engine frame fixed plate 5 ' by bolt 8 '.
In actual applications, there are many defects in the upper frame of the above-mentioned type.That is, being arranged on the top of longeron due to hoist engine 7 ', so that the center of gravity of the car body of piling machinery/rotary drilling rig is improved, cause the stability of whole machine poor.The raising of center of gravity can also increase the torque to the gyration gear ring on chassis.Further, since the pulling force that hoist engine is produced is delivered to longeron by bolt 8 ', so bolt 8 ' is easily damaged, hoist engine ground Joint failure is caused.
If in order to lower the center of gravity, must just reduce the link position of hoist engine.At some in the prior art, hoist engine is just connected directly between on longeron.But, for the big hoist engine of piling machinery, it is unpractical that hoist engine is connected directly between on longeron.Reason is, the volume of the main winch of big hoist engine particularly rotary drilling rig is larger, in order that it is connected directly between on two parallel longerons or is contained between two longerons, two spacing of parallel longeron must be increased, the increase of the spacing certainly will cause the connection of the anterior equipment armed lever of longeron to change and the installation of rotary motion mechanism is become complicated, bring a series of problems.
In the prior art, a rotary decelerating machine base 4 ' is only being set shown in Fig. 1, that is to say, that engaged with the swiveling gear on chassis only with a rotary reducer and drive the rotation of whole rotary drilling rig etc., this is resulted in, and flywheel moment is small, and rotation is unstable.And so that the swiveling gear on chassis is easy to abrasion, and thus the stationarity of rotation more deteriorates.
In another kind in the prior art, in order to avoid the installation conflict between each part, on the rebound that rotary reducer is arranged under upper frame base plate.This set causes that installation becomes complicated.
Finally, due in construction, piling machinery particularly rotary drilling rig is often rotated, so as to cause two longerons easily to distort.Long term accumulation, causes each equipment related to longeron to be affected.
The content of the invention
In order to solve the above-mentioned technical problem the present invention is exactly, there is provided a kind of upper frame for piling machinery particularly rotary drilling rig.
Larger hoist engine can be made more to be stably attached in upper frame it is an object of the present invention to provide a kind of, while not changing the upper frame of the position relationship of each equipment in upper frame also.It is a further object of the invention to provide a kind of upper frame of steady revolution.It is of the invention to a further object is, there is provided a kind of stronger upper frame of anti-torsion ability.
According to the first aspect of the invention, a kind of upper frame for piling machinery, including upper frame base plate, two longerons arranged in parallel, the rotary decelerating machine base and two swing arm support plates that are arranged on the upper frame base plate, the upper frame is characterised by, two longerons arranged in parallel be fixedly connected the upper frame base plate and it is parallel since the rear portion of the swing arm support plate extend back, the spacing between two longerons is arranged to be adapted to make the hoist engine to be set directly between two longerons with the width of hoist engine used.
According to this in a first aspect, because hoist engine used is arranged between two longerons being parallel to each other.So, the center of gravity of hoist engine declines.Two longerons arranged in parallel are parallel since the rear portion of the swing arm support plate extends back, it is to avoid the spacing between two longerons of increase causes the change of miscellaneous equipment installation site to accommodate while hoist engine.
According to the second aspect of the invention, two longerons arranged in parallel extend back setting since positioned at the rear portion of the swing arm support plate and the transverse slat that is fixedly connected with the dynamically supported plate.According to this aspect, the installation site of each equipment is optimized, make them more compact in upper frame.
According to the third aspect of the invention we, a connecting hole is respectively provided with the hoist engine position to be connected on two longerons arranged in parallel, hoist engine can be fixedly attached on longeron by the connecting hole and bearing.According to the third aspect so that hoist engine it is more firm and easily with longeron one install.
According to the fourth aspect of the invention, rotary decelerating machine base is set on the upper frame base plate of the lateral outer side of at least one swing arm support plate.
According to the fifth aspect of the invention, it is respectively provided with a rotary decelerating machine base on two upper frame base plates of the lateral outer side of the swing arm support plate.
According to the 4th and the 5th aspect so that the revolution of piling machinery/rotary drilling rig is more steady.Because torque is symmetrically transmitted, the use of the swiveling gear on chassis can also be greatly improved.
According to the sixth aspect of the invention, the thickness required for the thickness of the longeron is set greater than the moment of torsion that longeron resistance piling machinery is produced.According to this aspect, the anti-torsion ability of upper frame can be increased, ensure the good operation of vehicle.
Brief description of the drawings
Describe the present invention in detail below with reference to accompanying drawings, wherein：
Fig. 1 is the schematic diagram of upper frame of the prior art, wherein for clear explanation, showing hoist engine；
Fig. 2 is a kind of schematic diagram of embodiment of upper frame of the invention, in order to clearly be also shown for hoist engine.
Specific embodiment
Reference picture 2, it illustrates a preferred embodiment of the present invention.In the upper frame structure, the front portion of upper frame base plate 2 is provided with two swing arm support plates 4, and rotary decelerating machine base 1 is respectively arranged with the outside of two swing arm support plates 4, it is also possible to only set rotary decelerating machine base 1 in side.In the rear end connect setting transverse slat 6 of dynamically supported plate 4, two longerons 3 extend back from the transverse slat 6.Hoist engine 5 is arranged between two longerons, is fixedly connected with the hole on longeron by bearing, loads onto bearing cap after installing, and blending bolt fixes bearing cap, is so set and had both been ensured firmly connection, and maintenance easy to disassemble.The thickness of longeron 3 is set greater than the thickness required for longeron resists the moment of torsion that piling machinery is produced.In addition, the longeron is " I-beam " tee section, intensity is big.Because rotary reducer is preposition, upper frame is more compact in arrangement.Master winch is only installed, secondary elevator is then connected with each other with mast and connector, takes full advantage of space above in upper frame.
