Abstract
The utility model discloses a mobile draw bar locking device. The mobile draw bar locking device comprises movable machines arranged on draw bar locking platform rails, wherein a bottom millstone of each movable machine is in a rectangle-shaped frame structure, and one side of each bottom millstone in the rectangle-shaped frame structure is provided with an opening. Both the length and the width of the opening are larger than the diameter of a draw bar, and a mouth rim of each opening is in a horn-mouth-shaped structure. The mobile draw bar locking device has the advantages of being simple in structure, convenient to move, and capable of avoiding the inconvenience of using a temporary lifting appliance to load back and forth at each time when the draw bar is assembled and disassembled. Besides, the working efficiency and the safety of assembling and disassembling the draw bar are improved greatly.
Description
Technical field
The utility model relates to hydraulic hoist servicing unit in the Hydraulic and Hydro-Power Engineering, especially relates to portable pull bar locking device.
Background technology
In Hydraulic and Hydro-Power Engineering, pull bar (suspension rod) generally, when promoting fully or putting down equipment, is subjected to the travel limits of hydraulic hoist as the extending mechanism of hydraulic hoist, and the installation and removal of its pull bar must be faced with lifting and transportation problem.At present, be to utilize to open back and forth handling of the equipment of hanging in the installation and removal process of pull bar temporarily, because top also is connected with opening and closing device, operation is trouble, consuming time very.
Summary of the invention
The utility model purpose is to provide a kind of portable pull bar locking device of conveniently moving simple in structure.
For achieving the above object, the utility model is taked following technical proposals:
Portable pull bar locking device described in the utility model, comprise the locomotive that is arranged on the Draw bar lock fixed platform track, the bottom girder of described locomotive is rectangular frame structure, side at described rectangular frame structure bottom girder offers breach, the length of described breach and width are greater than the diameter of pull bar, and the opening's edge of breach is bell-mouth structure of air.
The utility model advantage is simple in structure, conveniently moving has been avoided each trouble of using interim lifting appliance to have bad luck back and forth in the installation and removal process of pull bar, simultaneously, has greatly improved operating efficiency and the safety of pull bar installation, dismounting.
