Abstract
The utility model discloses a handle mechanism for a prestress tensioning oil pump of a highway or railway bridge. The handle mechanism comprises a machine frame, wherein an oil pump body is arranged on the machine frame; a vertical motor is arranged on the oil pump body; an output shaft of the motor extends into the oil pump body and is in transmission connection with an input shaft of the motor; a traction handle is arranged at the front end of the machine frame; a fixed magnet is arranged on one side of the machine frame, which is close to the traction handle; a movable magnet which corresponds to the fixed magnet is fixed to the traction handle; and the traction handle is fixed by the attraction of the movable magnet and the fixed magnet. The handle mechanism has a simple structure and is reasonable in design; and the traction handle can be fixed conveniently and effectively under the mutual action of the fixed magnet and the movable magnet, so that the phenomenon that the traction handle is dragged is avoided, and the service life of the traction handle is prolonged.
Description
Technical field:
The utility model relates generally to stretch-draw oil pump field, relates in particular to the handle mechanism of highway, railroad bridge prestressed stretch-draw oil pump.
Background technology:
Highway in the prior art, railroad bridge prestressed stretch-draw oil pump include frame, and oil pump body is installed on the frame, and the perpendicular motor of putting is installed on the oil pump body, and the output shaft of motor stretches in the oil pump body and with its power shaft and is in transmission connection.
Stretch-draw oil pump in the prior art is because be applied to the building site, work under bad environment, and its traction handle causes traction handle dilatory everywhere owing to there is not special-purpose fastening devices, causes traction handle often to damage, and it is high to change frequency.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of highway rational in infrastructure, the handle mechanism of railroad bridge prestressed stretch-draw oil pump to be provided.
The utility model is realized through following technical scheme:
The handle mechanism of highway, railroad bridge prestressed stretch-draw oil pump includes frame, and oil pump body has been installed on the frame; The perpendicular motor of putting is installed on the oil pump body; The output shaft of motor stretches in the oil pump body and with its power shaft and is in transmission connection, and it is characterized in that: said frame front end is equipped with traction handle, near traction handle one side fixed magnet is installed on the frame; Be fixed with the movable magnet corresponding on the traction handle, movable magnet and fixed magnet adhesive fixed traction handle with fixed magnet.
The handle mechanism of highway, railroad bridge prestressed stretch-draw oil pump is characterized in that: said traction handle is rotatably installed in the frame front end.
The utility model has the advantages that:
The utility model is simple in structure reasonable in design, through the interaction between fixed magnet and the movable magnet, can fix traction handle easily and effectively, avoids traction handle to be stowed the generation of phenomenon, has prolonged the application life of traction handle.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to accompanying drawing.
The handle mechanism of highway, railroad bridge prestressed stretch-draw oil pump; Include frame 1; Oil pump body 2 has been installed on the frame 1, the perpendicular motor of putting 3 is installed on the oil pump body 2, the output shaft of motor 3 stretches in the oil pump body 2 and with its power shaft and is in transmission connection; Frame 1 front end is rotatablely equipped with traction handle 4; Near traction handle 4 one sides fixed magnet 5 is installed on the frame 1, is fixed with the movable magnet 6 corresponding on the traction handle 4, movable magnet 6 and fixed magnet 5 adhesive fixed traction handles 4 with fixed magnet 5.
