Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention is further illustrated by the following examples, which are not to be construed as limiting the invention.
Fig. 1 is a schematic structural view of a looper inlet concrete ceiling cutting device provided in an embodiment of the present invention; fig. 2 is a schematic sectional view along the line a-a in fig. 1. As shown in fig. 1 and 2, the excavation device provided in the embodiment of the present invention includes at least two chassis supports 1 spaced front and rear, both ends of the chassis supports 1 are detachably connected to steel columns 2 located on both left and right sides of the loop entrance; the two rail brackets 3 are arranged at intervals left and right, and the rail brackets 3 are erected on the chassis brackets 1 which are arranged at intervals front and back; the support 4 is arranged on the track support 3 in a sitting mode, the support 4 can slide forwards and backwards along the length direction of the track support 3, a plurality of support columns 5 are arranged on the support 4 at intervals along the width direction of the support 4, and one ends of the support columns 5 are detachably connected to the support 4; and the clamping plate 6 is used for bearing the rhinestone, and the clamping plate 6 can be adjusted along the height and width directions of the supporting upright post 5 and is fixedly arranged on the supporting upright post 5.
According to the invention, after the rhinestones are loaded on the clamping plate 6, the clamping plate 6 can be adjusted left, right and/or up and down, so that the rhinestones loaded on the clamping plate 6 are used for milling the side surface of the ceiling, after milling, the support 4 can be pushed inwards (a user only needs to coat lubricating grease on the track support 3), the second layer is milled continuously, and by analogy, the required grooves can be obtained by milling according to the design.
Specifically, in the invention, a first waist-shaped hole 7 is formed in the supporting upright post 5 along the height direction thereof, and a second waist-shaped hole 8 matched with the first waist-shaped hole 7 is formed in the clamping plate 6 along the width direction thereof, in the invention, the clamping plate 6 is fastened on the supporting upright post 5 through a fastening bolt 9 arranged in the first waist-shaped hole 7 and the second waist-shaped hole 8, specifically, as shown in fig. 2 and 3, the fastening bolt 9 in the invention comprises a first threaded section 13, a first smooth section 14, a second threaded section 15, a second smooth section 16 and a third threaded section 17, when in use, the fastening bolt 9 is arranged on the supporting upright post 5 and the clamping plate 6 in a penetrating manner, and then the first nut 10, the second nut 11 and the third nut 12 are respectively utilized to clamp and fasten the supporting upright post 5 and the clamping plate 6, and simultaneously, the first smooth section 14 can pass through the first waist-shaped hole 7, and the second smooth section 16 can pass through the, in the invention, when a user needs to adjust the clamping plate 6 left and right, the clamping plate 6 can be pushed left and right to carry out milling operation only by ensuring that the first nut 10 and the second nut 11 are in a fastening state and then slightly loosening the third nut 12; when the user needs to adjust the clamp plate 6 up and down, he or she can push the clamp plate 6 up and down for milling operation by first securing the second nut 11 and the third nut 12 in a fastened state and then loosening the first nut 10 slightly. The two-section smooth section design of the invention can effectively reduce the friction resistance when the operating personnel adjusts the splint 6 (or adjusts the splint left and right). Different from the X, Y two-way adjusting structure which may exist in the prior art, the structural design of the fastening bolt 9 of the three-section type threaded section in the invention can not only meet the clamping and adjusting requirements of the clamping plate 6, but also effectively shorten the adjusting operation radius, and most importantly, the adjusting operation radius can be effectively shortened, so that the adjusting and milling operation can be realized by only one operator when the cutting device provided by the invention is used for operation, the problem that the operation is inconvenient due to too much constructors caused by the limited construction space at the entrance of the loop can be effectively avoided, and simultaneously, the manpower resource can be effectively saved, thereby reducing the engineering cost.
On the basis of the technical scheme, further, the excavation device provided in the embodiment further comprises a plurality of limiting plates 18 which are arranged on the left side and the right side of the rail support 3 in pairs, the limiting plates 18 are arranged at the bottom of the support 4, and the limiting plates 18 matched with the rail support 3 are arranged on the support 4 to form a slide rail type structure, so that the support 4 is effectively prevented from sideslipping in the milling process.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
