Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical engineering, in particular to a gantry crane rope swing inhibitor. Background Art
[0002] Gantry crane is an important piece of engineering machinery. During operation, the trolley and spreader are connected by steel cables to form a simple pendulum-like system. Due to factors such as wind force, trolley acceleration and deceleration, spreader lifting and lowering, and mechanical vibration, the relative position between the trolley and spreader shifts and causes the spreader to shake. This shaking affects the safety of the operation process and reduces operating efficiency.
[0003] However, in the prior art, when a traditional gantry crane moves its hook, the hook may swing during the movement. If an incorrect operation is performed during the swing, the swing amplitude of the hook will increase. Since the traditional equipment has only one hook and is not equipped with a suppressor, the swing of the hook cannot be suppressed. The only option is to wait for the hook to stop swinging by itself before resuming the lifting work, thereby affecting production efficiency. Utility Model Content

[0025] Working principle:
[0026] When in use, first lower the hook 1 to a lower position through the rope 2 so that the staff can touch the hook 1, then stop the operation of the rope 2 to ensure the stability of the hook 1. After the position of the hook 1 is stable, the suppressor can be installed on the hook 1. Just wrap the main shell 31 and the auxiliary shell 33 in the quick-connect mechanism 3 around the hook 1, then align the mounting holes on the main shell 31 and the auxiliary shell 33 with the threaded groove 6 on the hook 1, then pass the bolt 5 through the main shell 31 and the auxiliary shell 33 and screw it into the hook 1, thereby fixing the main shell 31 and the auxiliary shell 33 on the hook 1. After the quick-connect mechanism 3 is installed, the connecting pipe 34 on the quick-connect mechanism 3 is put on the suppression mechanism 4, so that the two groups of air bags 41 on the suppression mechanism 4 are connected.
[0027] When installing the quick-connect mechanism 3 on the hook 1, it is only necessary to fit the main shell 31 and the auxiliary shell 33 on the hook 1, then adjust the positions of the main shell 31 and the auxiliary shell 33, align the mounting holes on the shell with the threaded groove 6 on the hook 1, then maintain the position of the shell, pass through the shell through the threaded groove 6 and screw it into the hook 1, thereby fixing the main shell 31 and the auxiliary shell 33 on the hook 1, so that the suppression mechanism 4 can be fixed on the hook 1. Because the catheters 43 on the two sets of airbags 41 protrude from the fixed shell 36, when installing the fixed shell 36 into the limit shell 32, it is only necessary to slide the auxiliary shell 33 from top to bottom into the limit shell 32. A sliding groove is provided on the limit shell 32 to facilitate the sliding in of the catheter 43.
[0028] After the suppression mechanism 4 is fixed on the hook 1, the two end connectors of the connecting tube 34 on the quick-connect mechanism 3 are then put onto the guide tubes 43 on the two groups of air bags 41, thereby connecting the two groups of air bags 41. The connecting tube 34 is fixed to the sub-shell 33 through the limiting ring 35. Then, the plugs 49 on the two groups of air bags 41 are pulled out, and the counterweight liquid is poured into the air bags 41 through the liquid inlet pipe 410. It should be noted that the air bags 41 cannot be completely filled, and it should be ensured that there is a gap in the air bags 41.
[0029] When the hook 1 swings, the counterweight 44 will slide along the direction of the swing of the hook 1. When the counterweight 44 slides along the limit column 46, the top spring 47 on the fixed plate 45 will be compressed, so that the top spring 47 accumulates elastic potential energy. The counterweight 44 is fixed with a push plate 48 through the sliding column 42. Therefore, when the counterweight 44 slides, the push plate 48 slides synchronously and squeezes the airbag 41, thereby squeezing the counterweight liquid in the airbag 41 to the conduit 43. The counterweight liquid in the conduit 43 is pushed by the subsequent counterweight liquid and flows through the connecting pipe 34 to the other group of airbags 41, thereby increasing the weight of the other group of airbags 41, thereby reducing the swing amplitude of the hook 1.
[0030] When the hook 1 swings in the opposite direction, the centrifugal force applied to the counterweight 44 decreases. When the thrust released by the top spring 47 is greater than the centrifugal force, the counterweight 44 is pushed to reset, and the airbag 41 is driven to reset. The other group of counterweights 44 also squeezes the counterweight liquid in the other group of airbags 41 into the resetting airbags 41, thereby changing the weight on both sides of the hook 1 and suppressing the swing of the hook 1.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor shall belong to the protection scope of the present application.
