Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1.
The floor beam grabbing and anti-loosening device shown in fig. 1 comprises: the device comprises a substrate 1, a gantry support 4, an anti-loosening driving device 14, a blocking rod 13, a double-sided rack 6, a single-sided rack 11 and a hook plate 12, wherein a mounting disc 3 is arranged at the top of the substrate 1, is conveniently connected with a manipulator, and is moved to the upside of an inverted bottom plate beam 8 through the manipulator to be pressed downwards.
The gantry support 4 is arranged at the bottom of the substrate 1, and in the embodiment, the top of the gantry support 4 can be fixed with the substrate 1 through bolts, so that the structure is firm. The double-sided rack 6 is vertically arranged in the gantry support and extends downwards, the guide plate 5 corresponding to the double-sided rack 6 is arranged in the gantry support 4, and the first guide groove corresponding to the double-sided rack 6 is arranged in the guide plate 5, so that the lifting stability of the double-sided rack 6 is ensured.
The bottom of the double-sided rack 6 is provided with a pressure head 7, in the embodiment, the double-sided rack 6 is sleeved with a return spring 9 between the pressure head 7 and the guide plate 5, and the elasticity of the double-sided rack 6 is pulled down. A pin shaft 10 located above the guide plate is arranged on the double-sided rack 6 to move downwards for limiting, and the problem that the double-sided rack 6 falls downwards is solved. When the mechanical hand drives the substrate 1 and the gantry support 4 to move downwards, the pressure head 7 is contacted with the bottom of the inner cavity of the bottom plate beam 8 to bear force, and the double-sided rack 6 is forced to move upwards to compress the return spring 9. In this embodiment, the width of the gantry support 4 corresponds to the width of the inner side of the floor beam 8, and the floor beam 8 can be centered.
The gantry support 4 is internally provided with gears 2 which are positioned at two sides of the double-sided rack 6 and are meshed with the double-sided rack 6, and when the double-sided rack 6 moves upwards, the gears 2 are driven to rotate. The single-sided rack 11 is horizontally arranged on two sides of the double-sided rack and meshed with the bottom of the gear 2, the single-sided rack 11 is driven by the gear 2, so that the single-sided rack 11 moves inwards when the double-sided rack 6 moves upwards, and in the embodiment, the gantry support 4 is provided with a second guide groove corresponding to the single-sided rack 11, so that the horizontal movement stability of the single-sided rack 11 is ensured.
The hook plate 12 is arranged at the bottom of the single-sided rack 11 and located on the outer side of the gantry support 4, when the single-sided rack 11 moves inwards, the hook plate 12 is driven to clamp two sides of the bottom plate beam 8, hook supports at the lower parts of the two sides of the bottom plate beam are carried out by utilizing the hook-shaped structure of the hook plate, the bottom plate beam 8 is prevented from sliding downwards, and the safety of the carrying process is improved.
The anti-loosening driving device 14 is arranged at the bottom of the base plate 1 and located above the outer end of the single-sided rack 11, and the stop rod 13 is arranged at the bottom of the anti-loosening driving device 14 to limit outward movement of the single-sided rack 11, so that loosening of the hook plate 12 is avoided, and the carrying safety is further improved.
