Description

A kind of large-scale milling machine milling room frame structure
Technical field
The present invention relates to a kind of large-scale milling machine milling room frame structure, it is adaptable to which the larger equipment size of tonnage is larger Milling machine, belong to engineering machinery field.
Background technology
In the research and development of large-scale milling machine, the high structure type of lightweight intensity can not only mitigate complete vehicle weight, moreover it is possible to save Energy resource consumption is saved, the inertia impact load of reducing mechanism improves structural life-time, especially true for its milling room frame structure.Greatly Type milling machine is due to requiring bigger milling size of wheel, bigger milling width, for installing the milling room framework of milling wheel just It is bigger.While the intensity in order to ensure structure, can be subjected to the shock loading of high-power milling and plane operation, the thickness of slab of frame structure is past Toward all increased, the weight of such milling room just further increases, Given this, it would be desirable to a kind of more excellent framework knot Configuration formula, can meet the job requirements of large-scale milling machine, can realize that lightweight intensity is high again, convenient processing and manufacturing.
The content of the invention
In order to overcome drawbacks described above, it is an object of the invention to provide a kind of large-scale milling machine milling room frame structure, meet While large-scale milling machine use requirement, integral frame structure intensity is high, lightweight;Structure optimization mode is simple, convenient processing Increase manufacturability.
In order to realize foregoing invention purpose, the technical solution adopted by the present invention is:A kind of milling for large-scale milling machine Room frame structure, including left wall plate, right wall plate, bending plate, rear seesaw, wing buttress brace, it is characterised in that:Right wall plate, left wall Plate is arranged in parallel in milling room framework both sides, is connected between right wall plate, left wall plate by bending plate and rear seesaw, bending plate and hind wing Plate is longitudinally connected by wing buttress brace, and scallop hole is disposed with left wall plate and right wall plate.
Preferably, scallop hole is opened up respectively on left wall plate and right wall plate, 150oSeveral scallop holes are evenly arranged in cambered surface.
It is highly preferred that using the direction of advance of car as starting point, first scallop hole and last scallop hole of left and right wallboard It is in 150oAngle, each scallop hole is evenly arranged;Wherein, first scallop hole of left wall plate and horizontal line are into 25oOn angle, right wall plate First scallop hole and horizontal line are into 0oAngle, the fan arc length degree of left wall plate is slightly longer than right wall plate fan arc length degree.
Elliptical aperture is provided with the top of the bending plate, elliptical aperture is located at the central area at the top of bending plate.It is described it is wing plus Brutal is longitudinally arranged in bending plate and rear seesaw top, the top surface complementary fit in shape risen and fallen with frame structure;Framework knot The top surface that structure rises and falls refers to the top surface of bending plate and rear seesaw.Scallop hole on left and right wallboard is furnished with fan-shaped shrouding so as to by sector Hole is sealed, and the top sealing plate that the elliptical aperture at the top of bending plate is also equipped with respective shapes seals elliptical aperture.The bending plate is by plate Bending is formed, and the width of forward position bending is more slightly larger than the width of rearward position bending, and the angle of downward bending is 45o, rear seesaw carried out bending in the side close to bending plate, and the angle of downward bending is 45o;Bending plate and rear seesaw are common The top of milling room framework is constituted, bending plate is arranged in the centre position of milling room frame roof, and rear seesaw is arranged in milling One in front and one in back mutually splicing constitutes the top surface of milling room framework for the position rearward in ceiling portion, bending plate and rear seesaw.Milling room frame Left on the right wall plate of frame and left bearing bore is left on right axle bearing hole, left wall plate, left bearing bore is connected by taking turns side Disk is used for installing milling wheel one end right axle bearing hole and is connected by bearing with the coupking shaft of milling wheel the completion milling wheel other end Lay, realize the connection between milling wheel and milling room framework.Milling room frame arrangement is in the middle part of vehicle frame, milling room framework The correspondence position that bottom plate in the middle part of four mounting seats, vehicle frame is arranged at top has four mounting holes, milling room mounting seat and vehicle frame mounting hole Between be attached by connector.Bending plate top surface is additionally provided with right graded beam seat and left graded beam seat.
Its primary structure of the invention has left wall plate, right wall plate, bending plate, rear seesaw and the different wing reinforcement of length Beam.Preferred scheme is:Six scallop holes are provided with left wall plate, using the direction of advance of car as starting point, first scallop hole and level Line is into 25oAngle, into 150 between first scallop hole and last scallop holeoAngle, 150oSix scallop holes are equal between cambered surface Even arrangement.Six scallop holes are provided with right wall plate, using the direction of advance of car as starting point, first scallop hole and horizontal line are into 0oFolder Angle, into 150 between first scallop hole and last scallop holeoAngle, 150oSix scallop holes are evenly arranged between cambered surface, with The scallop hole of left wall plate is compared, and the length of the fan-shaped fan arc of right wall plate is more slightly shorter.
The arrangement mode of this rule of scallop hole, not only alleviates weight, and ensure that left wall plate and right wall plate exist Strength and stiffness under various operating modes, while being convenient to CNC cutting, and avoid bolt hole, other structures part are not influenceed Assembling.
A slotted eye is provided with the top of bending plate, because position of opening has been selected in the minimum region of stress distribution, this Sample had both alleviated the weight of bending plate, and did not influenceed the carrying of integral frame structure.
Wing buttress brace is longitudinally arranged in bending plate and rear seesaw top, the wing of its shape picture expansion, with frame structure Just height coordinates the top surface of fluctuating, and not only stiffening effect is good but also compact conformation, lightweight.
Scallop hole on the wallboard of left and right is furnished with fan-shaped shrouding so as to which scallop hole is sealed, and the hole at the top of bending plate is also equipped with phase Answer the shrouding of shape to be sealed, due to shrouding thickness very little, can be reached sealedly in the case of the add weight that reduces as far as possible Effect.
Circular port is provided with the wall of left and right is used for the assembling of bearing block so as to the placement of milling wheel, on bending plate and rear seesaw There are four mounting seats, so as to which whole milling room frame structure is fixed on milling locomotive frame.
Relative to prior art, the beneficial effects of the invention are as follows:Left and right wallboard is provided with scallop hole, and its scallop hole is regular Arrangement not only alleviates weight but also ensure that the intensity of left and right wallboard;It is provided with the top of bending plate in the minimum region of stress Slotted eye, the carrying of structure is not influenceed while alleviating weight;Thin plate is employed to the hole after optimization sealedly to handle Mode, weight increase is few easily to be realized, not only stiffening effect is good but also compact lightweight for the wing buttress brace that has been longitudinally arranged of framework. While meeting large-scale milling machine use requirement, integral frame structure intensity is high, lightweight;Structure optimization mode is simple, convenient Processing increase manufacturability.
