Description
Technical field
The utility model relates to the erecting by overhang field, the driving mechanism of the removable erecting by overhang of particularly a kind of projector.
Background technique
The application of the removable erecting by overhang of projector in life is more and more general, for example dodge gate of supending roll type, movable window, and the hanging projector of mobile crane etc.Different with supending roll type dodge gate, movable window, the hanging projector of mobile crane to hang the position higher usually, so the structure of the removable erecting by overhang of projector and dodge gate, movable window erecting by overhang are different.The structure of the removable erecting by overhang of projector comprises hanger rail 1 and the suspender member 3 that is used to hang projector as moving track usually as shown in Figure 1, and suspender member 3 rolls by the hanging wheel 2 with hanger rail 1 coupling and is articulated in the hanger rail; The removable erecting by overhang of this projector need rely on staff to move suspender member and move the projector that articulates installation, and it hangs the position usually than higher, so it is convenient inadequately many times to operate.
The model utility content
At the prior art above shortcomings, the purpose of this utility model is to provide the driving mechanism of the removable erecting by overhang of a kind of projector, move in order to the electronic suspender member that orders about the removable erecting by overhang of projector, realize the motorized motions control of the removable erecting by overhang of projector, make the move operation of the hanging projector of mobile crane convenient.
For achieving the above object, the technological scheme that the utility model adopted is as follows: the driving mechanism of the removable erecting by overhang of projector, the removable erecting by overhang of described projector comprises hanger rail, and rolls by the hanging wheel with hanger rail coupling and to be articulated in suspender member in the hanger rail; It is characterized in that, described driving mechanism comprises the support body that can vertically be slidingly connected on described suspender member, the top of described support body is equipped with driving rolls, the coaxial worm gear that is provided with of described driving rolls, described worm gear mates engagement mutually with the worm screw that is driven by dc reversible electromotor, and described dc reversible electromotor is fixedly mounted on the support body; Also be connected with the extension spring that support body is upwards lifted between described support body and the suspender member, the driving rolls that described extension spring makes the support body top install offsets with the bottom surface of hanger rail and contacts.Adopt this driving mechanism,,, just can order about the driving rolls rolling by the transmission of worm and gear as long as with dc reversible electromotor energising and control its forward or reverse rotation; Again because the effect that lifts that extension spring makes progress to support body, making the driving rolls that is installed on the support body top offset with the bottom surface of hanger rail contacts, force of rolling friction between driving rolls and the hanger rail bottom surface forms driving force, drive interconnective support body and suspender member and move along hanger rail together, realized the motorized motions control of the removable erecting by overhang of projector.
As improvement, the material of described driving rolls rolling surface is a rubber.Utilize the strong frictional force of rubber rolling surface,, allow driving mechanism drive suspender member more smoothly and move to strengthen the driving force of driving rolls when rolling.
Compared to existing technology, the utility model advantage is, the suspender member that the driving mechanism of the removable erecting by overhang of this projector can electronicly order about the removable erecting by overhang of projector moves along hanger rail, realize the motorized motions control of the removable erecting by overhang of projector, made things convenient for the move operation of the hanging projector of mobile crane, and driving mechanism simple in structure, cost is low, install and use all very convenient.
Description of drawings
Fig. 1 is the perspective view of the existing removable erecting by overhang of projector;
Fig. 2 is the perspective view of the driving mechanism of the removable erecting by overhang of the utility model projector;
Fig. 3 is the vertical section structure schematic representation of the driving mechanism of the removable erecting by overhang of the utility model projector.
Embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is described further.
The structure of the driving mechanism of the removable erecting by overhang of the utility model projector as shown in Figures 2 and 3.The removable erecting by overhang of projector comprises hanger rail 1, and rolls by the hanging wheel 2 with hanger rail 1 coupling and to be articulated in suspender member 3 in the hanger rail; Driving mechanism comprises that one is provided with the support body 9 in vertical strip hole 13, utilizes bolt 12 to pass strip hole 13 support body 9 can vertically be slidingly connected on suspender member 3; The top of support body 9 is equipped with driving rolls 4, the driving rolls 4 coaxial worm gears 5 that are provided with, the below of worm gear 5 is provided with the dc reversible electromotor 7 that is fixedly mounted on the support body 9, the driving output shaft of dc reversible electromotor 7 is provided with worm screw 6, worm gear 5 and worm screw 6 coupling engagement mutually constitute Worm and worm-wheel gearing; Be positioned on the suspender member 3 support body 9 above also be provided with a fixed bolt 15, one end of extension spring 10 is articulated on the fixed bolt 15, the other end is articulated on the support body 9, by extension spring 10 support body 9 is upwards lifted, and the driving rolls 4 that makes support body 9 tops install offsets with the bottom surface of hanger rail 1 and contacts.Power control line 8 by dc reversible electromotor 7 is to its energising, control dc reversible electromotor 7 forwards or reverse rotation, ordering about driving rolls 4 by Worm and worm-wheel gearing rolls, force of rolling friction between driving rolls 4 and hanger rail 1 bottom surface forms driving force, drive interconnective support body 9 and suspender member 3 and move along hanger rail together, thereby the motorized motions that has realized the removable erecting by overhang of projector is controlled.The material of driving rolls 4 rolling surfaces preferably is chosen as rubber, utilizes the strong frictional force of rubber rolling surface, to strengthen the driving force of driving rolls 4 when rolling, moves thereby drive suspender member 3 more smoothly.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
