Abstract
The utility model belongs to a shaft coupling of a pavement paving and flatting machine. The utility model is composed of shaft coupling discs which are installed on both ends of a shaft head of a pipe, shaft coupling discs which are installed on supporting shaft heads on both sides, locking discs which are installed on the supporting shaft head, and shaft coupling screws, wherein, convex heads which are matched with concave grooves on the inner side surfaces of the shaft coupling discs on the supporting shaft heads are arranged on the outer side surfaces of the shaft coupling discs on the shaft head of the pipe. Screw holes which are corresponding to each other and can be inserted in the shaft coupling screws are respectively arranged on the shaft coupling discs and the locking discs. The shaft coupling of the utility model has the advantages of simple structure, convenient disassembly and assembly and provides favorable conditions for the application of the pavement paving and flatting machine.
Description
The utility model belongs to a kind of coupling body, particularly in a kind of hitch bar that is used for the rigid pavement spreading smoother.
At present, the axle supporting at the tubular axis of general rigid pavement spreading smoother and its two ends is for being fastenedly connected, and it is very inconvenient to dismantle, install, and badly influences being extensive use of of this class mechanism.
The purpose of this utility model is the problem at the dismounting inconvenience that exists in the prior art, proposes a kind of hitch bar of pavement spreading smoother, is installed between pipe spindle nose and the supporting spindle nose, makes pipe mounting or dismounting, replacing, very convenient.
The technological scheme of hitch bar of the present utility model is:
It is by the tray joint shaft that is contained in pipe spindle nose end, the tray joint shaft that is contained on the supporting spindle nose is sleeved on locking plate and the shaft coupling screw formation that supports on the spindle nose, the outer side surface of the tray joint shaft on the pipe spindle nose therein is provided with plush copper, it and the groove that is located on the tray joint shaft inner side surface that supports on the spindle nose match, and also offer the locking hole of the inserted shaft coupling screw of mutual correspondence on tray joint shaft and locking plate respectively.Being located at the circular-arc long strip aperture that the locking hole on the locking plate is made of the circular hole of two kinds of different-diameters, matches with the shaft coupling screw diameter in the aperture of minor diameter.On locking plate, also offer positioning pin hole.The screw of described shaft coupling is a long screw thick between the detail of two ends, be positioned at the diameter of the diameter at supporting spindle nose tray joint shaft place greater than two ends, and on the minor diameter screw rod at its two ends, be provided with screw thread, it partly can be screwed into and be fixed in the screw of the tray joint shaft on the pipe spindle nose than short screw, the other end can penetrate in the arcuation long strip hole of locking plate than long bolt, and available fixed by nut it.Be located at the plush copper on the tray joint shaft and the shape of groove and be cooperatively interact trapezoidal.
The major advantage of hitch bar of the present utility model is simple in structure, and easy accessibility is same for more advantageous conditions has been created in the application of rigid pavement spreading smoother, also can be applied in the last coupling body of miscellaneous equipment.
Fig. 1 is the exploded view of this hitch bar;
Fig. 2 is a shaft coupling screw enlarged view;
Fig. 3 is the front view of the locking plate in this hitch bar.
Embodiment:
Hitch bar as Figure 1-3, it is by the tray joint shaft (3) that is contained in pipe spindle nose (1) end, be contained in the tray joint shaft (4) on the supporting spindle nose (2), the locking plate (5) and the shaft coupling screw (6) that are sleeved on the supporting spindle nose constitute, the outer side surface of the tray joint shaft (3) on the pipe spindle nose (1) therein is provided with plush copper (7), it and the groove (8) that is located on tray joint shaft (4) inner side surface that supports on the spindle nose (2) match, and also offer the screw hole locking hole (9) of the inserted shaft coupling screw (6) of mutual correspondence on tray joint shaft (3,4) and locking plate (5) respectively.Being located at the circular-arc long strip aperture that the locking hole (9) on the locking plate (5) is made of the circular hole of two kinds of different-diameters, matches with the diameter of shaft coupling screw (6) in the aperture of minor diameter.On locking plate (5), also offer positioning pin hole (10).Described shaft coupling screw (6) is a long screw thick between the detail of two ends, be positioned at the diameter of the diameter located of supporting spindle nose tray joint shaft (4) greater than two ends, and on the minor diameter screw rod at its two ends, be provided with screw thread, it partly can be screwed into and be fixed in the screw of the tray joint shaft (3) on the pipe spindle nose (1) than short screw, the other end can penetrate in the arcuation long strip hole of locking plate (5) than long bolt, and available fixed by nut it.Be located at the plush copper (7) on the tray joint shaft (3,4) and the shape of groove (8) and be cooperatively interact trapezoidal.
The control that hitch bar of the present utility model is advanced and retreat by the Effector that is contained on the supporting base, the operating procedure during connection is:
1, the shorter micro screw with the shaft coupling screw partly screws in the screw of the tray joint shaft on the pipe axle;
2, the middle thicker part branch of shaft coupling screw passes the screw in the tray joint shaft that supports on the spindle nose;
3, again the other end of shaft coupling screw is passed the wide-aperture hole in the arcuation long strip hole on the locking plate than long screw portion;
4, rotation lock dish is relayed to screw in the mouth of small aperture from the large aperture, and will screw with nut.Insert locating stud then and fix it.
Otherwise, get final product the dismounting step.
