The invention relates to the technical field of marine cranes, in particular to a crane suspension arm shelf which comprises a shelf body arranged on a deck of a ship body and further comprises a clamping device and a bottom plate, the bottom plate is arranged at the top end of the shelf body, and first sliding rods are arranged at the four corners of the bottom plate in a sliding connection mode. The top of the first sliding rod is fixedly connected with a supporting plate. According to the crane lazy arm shelf, a lazy arm presses a supporting plate downwards to enable a first spring to deform, due to the fact that a sleeve rod is meshed with a rack, the sleeve rod can rotate under driving of the rack in the downward moving process of the supporting plate, due to the fact that a clamping rod is in threaded connection with the sleeve rod, and rotation of the clamping rod is limited by a limiting rod, the clamping rod can be clamped, and the clamping rod can be clamped. Therefore, rotation of the sleeve rod can drive the clamping rods to move towards the suspension arm, the supporting plate is continuously pressed downwards along with longitudinal movement of the suspension arm, the two sets of clamping rods can clamp the two sides of the suspension arm, and therefore the suspension arm can be transversely supported.
本发明涉及船用吊机技术领域,具体涉及一种吊机吊臂搁架,包括搁架主体,所述搁架主体设置在船体的甲板上,还包括夹持装置,包括底板,所述底板设置在搁架主体的顶端,所述底板四角滑动连接设置有第一滑杆,所述第一滑杆的顶部固定连接设置有支撑板。本发明提供的一种吊机吊臂搁架,吊臂通过下压支撑板使得第一弹簧产生形变,由于套杆与齿条啮合,支撑板在下移过程中套杆会在齿条的带动下转动,又由于夹持杆与套杆螺接且限位杆限制了夹持杆的转动,因此套杆的转动会带动夹持杆向吊臂移动,随着吊臂纵向移动不断下压支撑板,使得两组夹持杆能够夹持在吊臂的两侧,从而能够对吊臂起到一个横向支撑的作用。
