In addition, because the bolt hole on the fender bracket and the threaded hole on the fixed shaft adopt different processing standards during assembly, the problem that the positioning of the bolt hole is not matched with the fixed shaft easily occurs.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a track application protection frock for rail crane dolly can solve the simple application safeguard measure of taking on general rail crane dolly, often causes the dolly track to paint the pollution, can only polish the track before the examination car, causes paint and artifical extravagant problem.
In order to solve the technical problem, the utility model adopts the technical scheme that: the utility model provides a track for trolley track crane application protection frock, its innovation point lies in: comprises a protective frame, a fixed shaft, a roller, a positioning bolt and a handle;
the protective frame is of a U-shaped structure, a plurality of bolt holes for containing positioning bolts are arranged on two side edges of the protective frame at equal intervals along the extension direction, and the bolt holes on the two sides of the protective frame are symmetrical about the center of the protective frame;
the fixed shaft is arranged in the protective frame, and threaded holes matched with the positioning bolts are formed in the two ends of the fixed shaft; threaded holes at two ends of the fixed shaft and bolt holes on the protective frame are sequentially and coaxially arranged correspondingly; the positioning bolt penetrates through a bolt hole in the protection frame and is connected with a threaded hole at the end part of the fixing shaft, so that the fixing shaft is arranged in the protection frame;
the roller is of a cylindrical structure and is nested on the fixed shaft and can rotate around the fixed shaft.
Furthermore, the handles are provided with a pair of U-shaped structures and are arranged at bolt holes at two ends of the protection frame; through holes matched with the bolt holes are formed in the two ends of the handle; the positioning bolt penetrates through the through hole in the handle to press the handle on the outer wall of the protective frame.
Furthermore, an auxiliary positioning seat is arranged at a bolt hole of the protection frame; the outer contour of the auxiliary positioning seat is of a stepped shaft structure and is embedded into a bolt hole of the protective frame, and a through hole for accommodating the positioning bolt is formed in the center of the auxiliary positioning seat; the step surface of the outer contour of the auxiliary positioning seat is clamped on the outer wall of the bolt hole of the protection frame.
The utility model has the advantages that:
1) the utility model adopts the U-shaped frame as the protective frame, the roller can conveniently slide on the track by nesting the roller on the fixed shaft, and the tool is designed according to the height of the horizontal roller, so that the paint pollution to the side track of the horizontal roller can be effectively prevented; track polishing before trial run is reduced, and waste of paint and labor is avoided; in addition, an auxiliary positioning seat is installed on the bolt hole of the protection frame, the position machining precision requirement of the bolt hole is reduced, and the butt joint of the bolt hole fixing shaft is facilitated.
