Region（Central area i.e. at the top of bending plate）, the weight of bending plate had so both been alleviated, and do not influence integral frame structure
Carrying.Wing buttress brace is longitudinally arranged in bending plate and rear seesaw top, the wing of its shape picture expansion, is risen with frame structure
The top surface of volt just complementary fit in shape, the place that the top surface of framework is fallen in, wing buttress brace just protrudes, they
Complementary fit in shape, not only stiffening effect is good but also compact conformation, lightweight.
Scallop hole on left and right wallboard is furnished with fan-shaped shrouding（Respectively right scallop hole shrouding 12 and left scallop hole shrouding 13）
So as to which scallop hole is sealed, the top sealing plate 14 that the elliptical aperture 17 at the top of bending plate is also equipped with respective shapes is sealed, due to envelope
Plate thickness very little, can reach sealed effect in the case of the add weight that reduces as far as possible.
Circular port is provided with left and right wallboard（Respectively right axle bearing hole 18 and left bearing bore 19）Dress for bearing block
With the placement so as to milling machine wheel, there are four mounting seats on bending plate and rear seesaw（That is mounting seat I 7, mounting seat II 8, mounting seat
III 9, mounting seat IV 10）, substantially it is distributed on four angles in milling ceiling face, the distance between two forward mounting seats ratio is leaned on
Slightly a little further, substantially one isosceles trapezoid of line of four positions can will be whole by installing toilet for mounting seat distance afterwards
Individual milling room frame structure is fixed on milling locomotive frame.
As described above, the present invention can not only meet the use requirement of large-scale milling machine, and accomplish that intensity is high, weight
Gently, compact conformation is easy for installation.
General principle, principal character and the advantage of the present invention has been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, the original for simply illustrating the present invention described in above-described embodiment and specification
Reason, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
