Technical Field
The utility model relates to an elevator technical field, concretely relates to hauler frame device of platform ladder.
Background
The platform ladder is an elevator without a lift car, and the platform is driven by the traction of a traction machine to do reciprocating lifting motion along a fixed guide rail. Conventionally, a hoisting machine is usually mounted on a hoisting machine frame, and a governor is also mounted on the hoisting machine frame in order to simplify the structure. When the speed limiter is arranged on the front side of the traction machine, the longitudinal space of the platform ladder is easily occupied; when the overspeed governor was installed in the left and right side face of hauler, occupy the horizontal space of platform ladder easily, this two kinds of mounting means, the homoenergetic increases the upper end space of platform ladder.
SUMMERY OF THE UTILITY MODEL
The utility model discloses plan to provide a hauler frame device of platform ladder, let the overspeed governor install under the hauler, make the structure of whole hauler frame compacter, not too much occupy the space of platform ladder top.
Therefore, the utility model discloses the technical scheme who adopts does: the utility model provides a hauler frame set of platform ladder, includes the hauler frame that the level set up, be provided with the hauler mounting hole that is used for installing the hauler in the hauler frame, the interval is vertical about the rear side of hauler frame is provided with two piece at least well mounting panels that upwards extend, both ends are provided with downwardly extending's guide rail mounting panel about the hauler frame, the position department that the hauler frame is close to the right-hand member is provided with the overspeed governor support that is used for installing the overspeed governor downwards, the overspeed governor support is located the right side of hauler mounting hole, just is located the hauler frame under after the overspeed governor installation.
Preferably, a first reinforcing plate is provided between the hoistway mounting plate and the hoisting machine frame.
Preferably, the tractor frame is a bent piece with a downward groove, the guide rail mounting plates are arranged in the groove, and at least two frame reinforcing plates are arranged between the two guide rail mounting plates at intervals in the front-back direction.
More preferably, the upper end of the governor bracket is attached to the front end of the hoisting machine frame, and the lower end thereof is a U-shaped bent piece with a notch facing forward.
More preferably, a pad plate and a cushion pad are further provided between the hoisting machine and the hoisting machine frame.
More preferably, at least two sets of hoisting machine mounting holes are arranged in the middle of the hoisting machine frame in a staggered manner.
The utility model has the advantages that: a hoistway mounting plate is arranged at the rear end of the tractor frame, and a guide rail mounting plate is arranged below the hoistway mounting plate, so that the rear end of the tractor frame is mounted on the hoistway and is supported by the guide rail, and the whole tractor frame is firmly mounted; be provided with the overspeed governor support in the hauler frame to make the below of overspeed governor installation back just position hauler frame, make overall structure compacter, not too much occupy the space of platform ladder top, can not increase platform ladder space, thereby reduce the space of well.
Drawings
