Description
Technical field
The utility model relates to a kind of motor and drives supporter of semi-trailer.
Background technology
Superimposed trailer applies a kind of transportation means quite widely in modern transportation industry, superimposed trailer in motion its front end can be connected with tractor truck and to drag to be supported by it and to draw, the front end of superimposed trailer and tractor truck can be taken off when not travelling and hang, in order to support the front end of superimposed trailer after de-extension, the bottom of superimposed trailer front end is often provided with supporter of semi-trailer.Tractor truck and superimposed trailer to be thrown off, superimposed trailer pulling face need be raised, depart from tractor truck, tractor truck could be driven away.The supporting leg of traditional supporter of semi-trailer is made up of inside and outside two joint supporting legs, and extendable room is little, does not make full use of the effective length of screw mandrel; Usually in supporting process, need operator to be risen by supporting leg with the hand handle that shakes, after tractor truck connects superimposed trailer, also need operator to be put down by supporting leg with hand rocking handle, whole process consumes time is long, and work efficiency is low.
Utility model content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, and extendable room is large, and without the need to being elevated supporting leg manually, a kind of motor that work efficiency is high drives supporter of semi-trailer.
The technical scheme that the utility model adopts for this reason is:
Comprise external support leg, middle supporting leg and internal support leg, described external support leg, middle supporting leg and internal support leg are successively in sliding block joint, screw mandrel is provided with in described external support leg, described screw mandrel lower end cover has nut, described nut is fixedly connected with internal support leg upper end, middle supporting leg is provided with locating dowel pin, correspondingly on the sidewall of external support leg be provided with position-limited trough, locating dowel pin is stuck in position-limited trough and can moves up and down, described screw mandrel upper end is connected with gear drive, the input shaft of described gear drive is connected with reduction gear, the input shaft of reduction gear is connected with drive motor.
Further, described drive motor is DC machine, and described DC machine is provided with overload safety device.
Further, described external support leg upper end is provided with adapter plate, is provided with reinforced rib between described adapter plate and external support leg sidewall.
Further, the lower end of described internal support leg is hinged with step disk.
The utility model has the advantages that:
The utility model structure is simple, and extendable room is large, by the lifting adopting motor to drive bearing set, reduces the labour intensity of operator, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 be external support leg, 2 are middle supporting legs, 3 are internal support legs, 4 are screw mandrels, 5 are nuts, 6 are locating dowel pins, 7 are position-limited troughs, 8 are gear drives, 9 are reduction gears, 10 are drive motor, 11 are adapter plates, 12 is step disks.
