TECHNICAL FIELD
[0001] The utility model belongs to the technical field of small -size crane, concretely relates to a pull -out storage mechanism of fly -arm rotatable storage. BACKGROUND
[0002] The fly arm of small -size crane is installed with a big arm similar to that on the crane at the front end of the forklift, drives the fly arm to retract or lift through the power system of the forklift, after the fly arm crane is installed on the forklift, the performance is greatly promoted, and it is simple and convenient to operate. Since the cost of forklift itself is low, plus the relatively low modification cost, the overall cost of small -size crane fly arm is low, and there are various specifications, such as 5.4 meters (four sections), 6.6 meters (five sections), 7.9 meters (six sections), 9.3 meters (seven sections), 10.5 meters (seven sections) etc. When selecting, the appropriate length needs to be determined according to the tonnage and working environment of the forklift. Generally speaking, the smaller the tonnage of the forklift, the shorter the fly arm crane used by the forklift, and the larger the tonnage of the forklift, the longer fly arm crane can be used.
[0003] Specifically, the design intention of the fly arm of small -size crane is to expand the operation range of the crane, so that it can more conveniently carry out hoisting operation to various objects. The connection mode between the fly arm and the crane mechanical arm adopted by the traditional small -size crane mostly relies on bolt fastening or welding technology to realize butt joint. These fly arms not only have flexible functions of rotation and folding to adapt to the needs of different working environments, but also usually reserve certain gaps in design to ensure smooth and unobstructed during the process of rotation and folding. However, this traditional rotation butt joint mode has a significant defect: the connection position between the mechanical arm and the fly arm is weakened due to the existence of the gap, which not only affects the stability and safety of the crane operation, but also shortens the service life of the fly arm and increases the cost of maintenance and replacement.
