I. Innovation of the crane

1. Technical difficulties conquered by this design:

The lifting mechanism is arranged on the inside of the trolley end beam and the main beam;

The trolley running mechanism adopts the form of direct connection between the trolley and the main beam to replace the end beam;

Hook beam and pulley shaft are combined to minimize the size from the bottom of the hook to the top of the pulley.

2. Technical working point solutions.

The trolley type super clearance hook bridge crane adopts the design of super clearance, reducing the height of the trolley and the trolley to the lowest, and lifting height to the highest under the same conditions. This structure can be used in the workshop space is limited to meet the common type of bridge crane can not be used. Three technical measures have been taken:

The lifting mechanism is arranged on the inside of the trolley end beam and the main beam, and the upper plane of the whole lifting mechanism is lower than the top of the trolley end beam, which effectively reduces the overall height of the crane.

The trolley running mechanism adopts the form of direct connection between the trolley and the main beam, and the two are flush to replace the end beam; The workshop adopts tie rod connection, and adopts heavy jointed wheel. This structure distributes the stress point of the wheel, reduces the maximum force of a single column, and can be used in the steel structure workshop without strengthening the column.

The hook group adopts compression directly connected mountain hook, hook beam and pulley shaft are combined into one, to minimize the size from the bottom of the hook to the top of the pulley, under the same conditions can make the lifting height to the highest.

Ii. Comparative analysis and overall analysis of the scientific and creative nature of the results

According to the science and technology report, it can be concluded that the super clearance design form used by the trolley type hook bridge crane: 1. The lifting mechanism is arranged on the inside of the trolley end beam and the main beam; 2. The trolley running mechanism adopts the form of direct connection between the trolley and the main beam to replace the end beam; 3. Hook beam and pulley shaft are integrated to minimize the size from the bottom of the hook to the top of the pulley.
