Description
Technical Field
The utility model relates to a milling machine ceiling stand clearance adjustment device belongs to the milling machine field.
Background
The road milling machine is a special mechanical device for maintenance operation of highways and urban roads, and is mainly used for excavation and renovation of asphalt concrete surface courses of highways, airports, wharfs, parking lots and the like, removal of road surface diseases such as rutting, cracking, carbuncle bags, road surface marks and the like of asphalt road surfaces, galling of cement road surfaces, milling and leveling of staggered platforms of the surface courses and the like. The ceiling of the small and medium-sized milling machine is generally made to be vertically liftable in order to meet the height requirements of transportation and work. At present, the clearance between the stand columns is not adjustable, and due to the problems of manufacturing, processing and the like, the lifting and clamping stagnation of the small ceiling in the clearance can occur, or the problem of severe shaking of the large ceiling in the clearance can occur.
Disclosure of Invention
To the problem that above-mentioned prior art exists, the utility model provides a milling machine ceiling stand clearance adjustment device makes the ceiling go up and down smoothly and do not have and rock.
In order to achieve the purpose, the milling machine ceiling stand column gap adjusting device comprises a ceiling, an inner stand column, an outer stand column and a portal frame, wherein the ceiling is installed on the inner stand column, the inner stand column is installed on the outer stand column, and the outer stand column is installed on the portal frame; the nylon plate is arranged between the inner upright post and the outer upright post;
the outer upright post is provided with a threaded seat, the threaded seat is internally provided with an adjusting stud, and the nylon plate is provided with a screw which is matched and connected with the adjusting stud.
As an improvement, a hand-operated self-locking winch is installed on the outer stand column, and the inner stand column is connected with the hand-operated self-locking winch and controlled to lift by the hand-operated self-locking winch.
As an improvement, the ceiling is installed on the inner upright post through bolts.
As an improvement, the outer upright post is installed on the portal frame through a bolt.
As an improvement, a nut is arranged on the adjusting stud and is abutted against the threaded seat.
Compared with the prior art, the utility model discloses a milling machine ceiling stand clearance adjustment device through the rotation regulation double-screw bolt, adjusts the clearance between nylon board and the inner column, both can make the ceiling oscilaltion smoothly not have the jamming, can make the ceiling can not rock because the clearance is big again.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is an internal cross-sectional view of the present invention;
in the figure: 1. the self-locking device comprises a ceiling, 2, an inner upright post, 3, a hand-operated self-locking winch, 4, an outer upright post, 5, a portal frame, 6, a threaded seat, 7, a nut, 8, an adjusting stud, 9, a nylon plate, 10 and a screw.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
As shown in fig. 1 and 2, a milling machine ceiling column gap adjusting device comprises a ceiling 1, an inner column 2, an outer column 4 and a portal frame 5, wherein the ceiling 1 is installed on the inner column 2, the inner column 2 is installed on the outer column 4, the outer column 4 is installed on the portal frame 5, and the milling machine ceiling column gap adjusting device further comprises a nylon plate 9 installed between the inner column and the outer column;
the outer upright post 4 is provided with a threaded seat 6, the threaded seat 6 is internally provided with an adjusting stud 8, and the nylon plate 9 is provided with a screw 10 which is connected with the adjusting stud 8 in a matching way.
As an improvement of the embodiment, a hand-operated self-locking winch 3 is installed on the outer stand column 4, and the inner stand column 2 is connected with the hand-operated self-locking winch 3 and controlled to lift by the hand-operated self-locking winch 3. The integral lifting of the ceiling 1 and the inner upright post 2 is controlled by the hand-operated self-locking winch 3 to be more convenient and labor-saving.
As a modification of the embodiment, the ceiling 1 is mounted on the inner upright 2 by bolts; the outer upright post 4 is installed on a portal frame 5 through bolts. Adopt bolted connection, the dismouting is more convenient.
As an improvement of the embodiment, the adjusting stud 8 is provided with a nut 7, the nut 7 is abutted against the threaded seat 6, and the loosening of the adjusting stud 8 can be effectively prevented through the nut 7.
When the ceiling is used, the adjusting stud 8 is rotated, the adjusting stud 8 and the screw 10 are screwed or unscrewed according to different rotation directions, and when the adjusting stud 8 and the screw 10 are screwed, the gap between the nylon plate 9 and the inner upright post 2 is increased, so that the ceiling 1 can smoothly ascend and descend without clamping stagnation; when the adjusting stud 8 and the screw 10 are loosened, the gap between the nylon plate 9 and the inner upright 2 is reduced, so that the inner upright 2 cannot shake due to large gap.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
