Description

Driving davit

Technical Field

The utility model relates to an electroplating production line subassembly, the driving davit that installs on the driving a vehicle, is used for handling the part specifically says so.

Background

At present, traditional driving davit includes the bracing piece that the level was arranged, and the bottom at bracing piece both ends all has the lifting hook of vertical arrangement, and the hook door of lifting hook all arranges towards the direction of keeping away from another lifting hook. When in use, the suspension arm is arranged on a corresponding travelling crane on the electroplating bath. During hoisting, the parts are hung between the two lifting hooks. The distance between two lifting hooks of the crane jib is determined, and only parts with corresponding sizes can be hung. Therefore, the electroplating bath adopting the travelling crane boom can only electroplate parts with the same size, and the large and small parts cannot be electroplated in the same electroplating bath, so that the number of the electroplating baths is greatly increased, and the occupied area of the whole electroplating production line is larger. Moreover, different electroplating baths need to be frequently replaced when parts with different sizes are electroplated, and the working efficiency is lower.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a driving davit, adopt this davit can reduce electroplating production line's area, improve work efficiency.

In order to solve the problems, the following technical scheme is provided:

the utility model discloses a driving davit's characteristics are the frame including the rectangle, and this frame is the level and arranges, and the middle part of its two minor faces all has the horizontal connecting rod of outside stretching out, and the bottom of horizontal connecting rod all has the vertical fixed lifting hook of arranging, is reverse arrangement between the hook door of two fixed lifting hooks. A movable trolley is arranged between the two long edges of the frame, and a driving mechanism is arranged between the movable trolley and the frame so as to drive the movable trolley to move longitudinally along the frame. The bottom of the movable trolley is provided with two vertically arranged movable lifting hooks, the hook doors of the two movable lifting hooks are arranged in a reverse direction, the fixed lifting hooks and the movable lifting hooks are the same in height, and the fixed lifting hooks and the movable lifting hooks are on the same straight line.

The driving mechanism comprises two rotating shafts located on the movable trolley, the rotating shafts are in rotating fit with the movable trolley, the two rotating shafts are arranged in parallel and side by side, the two rotating shafts are parallel to the short edge of the frame, and the two ends of the rotating shafts are equally divided and extend out of the two sides of the movable trolley to the upper portions of the two long edges of the frame respectively. The top on the long limit of the frame is provided with racks arranged along the longitudinal direction of the frame, the two ends of the rotating shaft are provided with gears, and the gears are meshed with the corresponding racks. One of the rotating shafts is provided with a driven chain wheel, the movable trolley is provided with a motor, an output shaft of the motor is provided with a driving chain wheel, and a chain is sleeved between the driving chain wheel and the driven chain wheel.

And reinforcing rods are arranged between the two ends of the short edge of the frame and the outer ends of the corresponding horizontal connecting rods.

By adopting the scheme, the method has the following advantages:

because the utility model discloses a driving davit including the frame, the middle part of two minor faces of frame all has the horizontal connecting rod that outwards stretches out, and the bottom of horizontal connecting rod all has the vertical fixed lifting hook of arranging, has movable dolly between two long limits of frame, has actuating mechanism between movable dolly and frame, and there are two vertical movable lifting hooks of arranging bottom of movable dolly, is reverse arrangement between movable lifting hook's the hook door. When the part hanger is used, the position of the movable trolley is controlled according to the size of the part, and the part is hung between a movable lifting hook and a fixed lifting hook opposite to a hook door of the movable lifting hook. Therefore, the electroplating bath provided with the suspension arm can be used for electroplating parts with different sizes, thereby reducing the number of electroplating baths on an electroplating production line and reducing the occupied area of the electroplating production line. Moreover, parts with different sizes are electroplated without replacing the electroplating bath, thereby greatly improving the working efficiency of electroplating.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the traveling crane boom of the present invention is characterized in that the frame 3 comprises a rectangle, the frame 3 is horizontally disposed, the middle portions of two short sides of the frame all have the horizontal connecting rod 1 extending outwards, the bottom of the horizontal connecting rod 1 all has the vertically disposed fixed hook 9, and the hook doors of the two fixed hooks 9 are reversely disposed. A movable trolley 7 is arranged between the two long edges of the frame 3, and a driving mechanism is arranged between the movable trolley 7 and the frame 3 so as to drive the movable trolley 7 to move longitudinally along the frame 3. The bottom of the movable trolley 7 is provided with two vertically arranged movable lifting hooks 8, hook doors of the two movable lifting hooks 8 are arranged in a reverse direction, and the fixed lifting hooks 9 and the movable lifting hooks 8 are the same in height and are all on the same straight line.

The driving mechanism comprises two rotating shafts 6 positioned on a movable trolley 7, the rotating shafts 6 are in rotating fit with the movable trolley 7, the two rotating shafts 6 are arranged in parallel and side by side, the rotating shafts are parallel to the short edges of the frame 3, and the two ends of each rotating shaft 6 are equally divided and extend out of the two sides of the movable trolley 7 to the upper parts of the two long edges of the frame 3. The top on the long limit of frame 3 all has along its longitudinal arrangement's rack 4, the both ends of pivot 6 all have gear 5, and gear 5 is in the same place with corresponding rack 4 meshing.
