Description

Built-in trolley crane

This creation is about an overhead crane, especially a built-in trolley crane.

The overhead crane is a type of overhead crane, commonly known as the "Trolley", which is an indispensable equipment for modern industrial production.

In general, cranes vary in function and use, and their appearance and shape are also varied. However, no matter what kind of functional crane, the crane is equipped with lifting gears, reels, steel cables and hooks for vertical lifting and handling of goods.

For a practical example of a conventional bridge crane 100, please refer to Figure 1. Wherein, the bridge cart of the crane 100 runs longitudinally along the rail 10 laid on the elevated rails on both sides, and the hoisting mobile cart (car) 30 runs laterally along the transverse beam 20 of the laying bridge, and the hoisting mobile vehicle is further provided with Steel cable cranes, through the reel, steel cable, and hook group (not shown) to vertically lift and transport goods, so that goods can be randomly hoisted along the XYZ three-dimensional direction within a working range, and the space under the bridge can be fully utilized to lift materials. Blocked by ground equipment, there is a walkway 40 on the side of the crane to provide maintenance personnel to walk around. Bridge cranes are widely used in indoor and outdoor warehouses, factories, docks and open storage yards to lift heavy objects or facilitate the handling of large materials.

However, at present, the crane truck 30 of such a bridge crane is likely to collide with foreign objects during the sliding of the transverse beam 20 to cause damage or malfunction. Therefore, the design of such a traditional bridge crane still needs to be improved.

In order to overcome the shortcomings and shortcomings of the existing conventional overhead crane, the present invention provides a built-in trolley crane, which comprises: a beam, a trolley body, a maintenance walkway, two longitudinal running tracks, two longitudinal running vehicles, two longitudinal Drive unit. Wherein, the beam is disposed transversely; the body of the trolley is disposed on the beam and can be driven to move laterally back and forth. The maintenance walkway is placed laterally along the cross member for maintenance personnel to move for maintenance. The two longitudinal running rails allow the beam to move longitudinally back and forth. The two longitudinal running vehicles are respectively disposed on the two longitudinal running rails, and are respectively fixed at two ends of the cross beam, and the cross beam can be driven to move back and forth longitudinally by the two longitudinal running vehicles. The two longitudinal driving devices are respectively fixed on the two longitudinal running vehicles to drive the longitudinal running vehicle to move back and forth longitudinally to drive the beam to move back and forth longitudinally.

In the present creation, the body of the trolley includes: a horizontal wheel, a steel cable, a main hook, and a pair of hooks. The traversing wheel can be laterally rotated along the beam to drive the trolley body to move laterally. The cable is disposed at a lower portion of the main body of the trolley, and is operable to move up and down to drive the main hook of the lower portion of the cable to move up and down, and to move the heavy object hooked by the main hook up and down. The secondary hook can be used for hooking general objects.

In the present creation, the longitudinal section of the beam may have the shape of a channel steel, a steel, or a box beam, and the body of the trolley is disposed in the groove to be driven to move laterally back and forth.

In the present creation, the built-in trolley crane includes: the trolley body, the beam, the maintenance walkway, the four longitudinal driving devices, the two longitudinal running rails, and the two longitudinal running vehicles Made from steel.

Summarizing the above description, compared with the traditional overhead crane, the advantages of the present creation are: In the present creation, the body of the trolley is sandwiched and fixed on the two inner sides of the transverse beam, and is located in the concave portion between the two sides of the beam. It is protected that the body of the trolley can be prevented from easily touching foreign objects when moving laterally back and forth to cause malfunction or damage.
