Detailed Description
For a further understanding of the present utility model, the present utility model will be described in detail with reference to the drawings and examples. It is to be understood that the examples are illustrative of the present utility model and are not intended to be limiting.
Example 1
As shown in fig. 1-3, the present embodiment provides a weight-adjustable hook suitable for a floor rocker arm, which includes a hook main body 110, the hook main body 110 includes a running block 160, weight components for adjusting the weight of the running block 160 are disposed at side walls at two ends of the running block 160, and the running block 160 is provided with a hook 310 hinged with the running block 160.
Through the arrangement of the hook main body 110, the running pulley 160, the counterweight assembly and the hook 310 in the embodiment, when the iron tower is hoisted, when the iron tower height exceeds a certain height, a worker adds corresponding weight to the running pulley 160 through the counterweight assembly on the running pulley 160 so as to balance the moment of the luffing rope to the support, thereby ensuring the stability of the rocker arm when the rocker arm is retracted, and preventing the hook 310 from automatically closing the rocker arm when the specified height is not reached; thereby better protecting the safety of constructors.
In this embodiment, the counterweight assembly includes a plurality of counterweight plates 140 stacked together, a plurality of support rods 130 penetrating through the counterweight plates 140 are disposed at side walls of two ends of the running block 160, and a first through hole 210 for the support rods 130 to penetrate is disposed on the counterweight plates 140; the side walls at the two ends of the running block 160 are also provided with threaded rods 120 penetrating through the weight plates 140, the weight plates 140 are provided with second through holes 230 for the threaded rods 120 to penetrate through, and one end of the threaded rods 120 away from the running block 160 is provided with nuts 220 matched with the threaded rods 120 to tightly prop against the weight plates 140.
Through the arrangement of the weight plate 140, the support rod 130, the first through hole 210, the threaded rod 120, the second through hole 230 and the nut 220 in the embodiment, when the iron tower is hoisted to a certain height, a constructor can respectively pass through the support rod 130 and the threaded rod 120 with a proper amount of weight plate 140, when the total weight of the passed weight plate 140 and the running block 160 reaches a specified weight, the constructor can screw the nut 220 into the threaded rod 120 and prop against the weight plate 140, thereby being better convenient for the constructor to adjust the total weight of the running block 160, and simultaneously preventing the weight plate 140 from sliding off the support rod 130 and the threaded rod 120 in the lifting process of the running block 160;
