Based on the embodiments of the present utility model, all other embodiments obtained by a person skilled in the art without making any inventive effort are within the scope of the present utility model.

Referring to fig. 1-11;

aiming at the problems mentioned in the background art, the embodiment of the utility model provides a rotation stopping hanger to solve the technical problems, and the technical scheme is as follows:

an anti-sway swivel hanger comprising:

a base 140; specifically, the base 140 includes two bracket bases made of a plurality of square tubes by welding; the two bracket seats are fixed on the mounting surface at intervals;

two suspension arms 110 rotatably connected to the base 140, respectively; specifically, each boom 110 is individually rotatably connected to a support base;

the top of the two suspension arms 110 is provided with bearing blocks, and two ends of the beam 120 are respectively and rotatably connected to bearings of the bearing blocks at the top of the two suspension arms 110;

further comprising a hanger 130, a heave prevention mechanism 200 and a driving mechanism; wherein,

the hanger 130 is vertically fixed on the cross beam 120;

an anti-sway mechanism 200 is provided on the boom 110 for preventing the hanger 130 from swaying on the cross beam 120.

FIGS. 1-3 illustrate; in this embodiment, when the hanger 130 is initially installed on the beam 120, only the hanger 130 needs to be vertically fixed on the beam 120; thus, no matter how the boom 110 rotates, the anti-swing mechanism 200 can ensure that the hanger 130 keeps a vertical state and does not swing back and forth, and the situation that the workpiece collides with peripheral devices due to large swing amplitude can not occur.

In this embodiment, the base 140 is fixedly connected to a rotating shaft, and the bottom of the suspension arm 110 is rotatably connected to the rotating shaft; the rotating shaft is not rotatable in the present utility model, and is fixed to the base 140.

the second chain 232 is engaged with the lower sprocket 220;

the two adjusting rods 240 are included, and the two adjusting rods 240 respectively fixedly connect two ends of the same side of the first branch chain 231 and the second branch chain 232.

In this embodiment, the chains are set as the first branch chain 231 and the second branch chain 232, and are connected by the adjusting rod 240, which is designed as follows:

1. when the chain is actually assembled, the total length of the required chain is difficult to ensure to be an integral multiple of the number of chain sections, and the chain wheel can be meshed and driven only by adding a complete chain link;

however, this can cause loosening during the meshing drive of the chain and sprocket, affecting the anti-rattle strength of anti-rattle mechanism 200;

2. meanwhile, a part of the chains are replaced by the adjusting rods 240, so that the overall structural strength of the chains can be increased, and the chains are convenient to install and adjust.

Fig. 6 and 11; in this embodiment, the adjusting lever 240 includes a lever body and hooks 241 fixed on two sides of the lever body; wherein, hooks 241 at two sides of the adjusting rod 240 are respectively hooked on the chain shaft at the end part of the same side chain; the length of the rod body is designed according to actual needs.

Fig. 6 and 11; in this embodiment, the locking member 250 is further included to firmly lock the adjusting lever 240 to the chain;

the locking member 250 comprises a lock body, a U-shaped lock cylinder 253 and a nut 254;

the lock body comprises two plate bodies 251 and a connecting plate 252;

the free end of the hook 241 extends to the rod body;

the top of the plate body 251 is respectively provided with a clamping groove, and the clamping grooves are clamped at the contact positions of the rod body and the free ends of the hooks 241;

two support arms of the U-shaped lock core 253 are respectively inserted into insertion holes on two sides of the connecting plate 252;

the two arms of the U-shaped lock core 253 are provided with a section of screw thread, and a nut 254 is connected to the screw thread of the arm of the U-shaped lock core 253.

Fig. 5, 8 and 10; in this embodiment, the driving mechanism includes two groups, each group of driving mechanism drives one suspension arm 110 individually; wherein,

the drive mechanism includes a linear drive 310, a short arm 320, and a link 330; the linear actuator 310 is preferably an electric cylinder or an air cylinder;

the short arm 320 is hinged to the base 140;

one end of the connecting rod 330 is hinged on the suspension arm 110, and the other end of the connecting rod is hinged on the top of the short arm 320;

the linear actuator 310 is pivotally connected to the base 140 at its rear end and to the short arm 320 at its driving end.

In this embodiment, the short arm 320, the link 330, the boom 110, and the base 140 form a stable four-bar linkage; by controlling the length of the short arm 320 and the connecting rod 330 and the connection positions of the short arm 320 and the connecting rod 330 with the suspension arm 110 and the base 140, a double-rocker structure or a crank-rocker structure can be formed, the rotation angle of the suspension arm 110 is increased, and the requirement of the lowering position of the sonar 500 under more conditions is met.

The working principle of the anti-swing rotary hanger provided by the embodiment of the utility model is as follows (taking figures 2, 9 and 10 as references):

1. the debugging equipment enables the suspension arm 110 to be in a vertical setting state when initially installed on the cross beam 120;

2. the linear actuator 310 pushes the short arm 320 to rotate, and the link 330 in turn pushes the boom 110 to rotate about the base 140; because the lower sprocket 220 is fixed on the base 140 so as not to rotate, a part of the chain is wound into the lower sprocket 220 on the left side of the lower sprocket 220, and a part of the chain is separated from the lower sprocket 220 on the right side of the lower sprocket 220;

3. at this time, the chain wound into the left side of the lower sprocket 220 becomes shorter, the chain wound out of the right side of the lower sprocket 220 becomes longer, since the chains on both sides of the lower sprocket 220 are arranged in parallel with equal length, the chain on the right side of the upper sprocket 210 is forced to drive toward the lower sprocket 220, the chain on the left side of the upper sprocket 210 is driven away from the lower sprocket 220,

4. the chain drives the upper chain wheel 210 and the suspension arm 110 to rotate at equal angles in the opposite direction, and drives the cross beam 120 and the upper chain wheel 210 to rotate synchronously, so that the cross beam 120 rotates at the same angle in the opposite direction no matter how much the suspension arm 110 rotates, so as to keep the vertical state of the suspension 130 and avoid the condition of swinging back and forth.

The anti-swing rotary hanger provided by the embodiment of the utility model has the following beneficial effects: according to the utility model, through the matched design of the structures, the hanging frame cannot swing back and forth and can always keep a vertical state in the rotating process of the hanging arm, so that the workpiece or peripheral equipment is prevented from being damaged due to collision.
