Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a fixing structure for a civil crane comprises a hook 1 and a limit hook 3, a slot 2 matched with the limit hook 3 is arranged inside the hook 1, a second plate 8 is fixed on the top of the hook 1, a telescopic slot 14 is arranged on the top end inside the second plate 8, a return spring 12 is fixed inside the telescopic slot 14, a telescopic column 13 is fixed on the tail end of the return spring 12, a first plate 6 is fixed on the tail end of the telescopic column 13, a limit mechanism is fixed on the front surface and the rear surface of the hook 1, when an object is hung and lifted, the first plate 6 and the second plate 8 are gradually stretched due to the weight of the object, so that the exposed steel wire ropes 7 are gradually increased, meanwhile, the rotary column 11 rotates to complete the loosening of the steel wire ropes 7, the rotary column 11 drives the limit hook 3 to rotate and gradually enter the slot 2, simultaneously under the effect of clockwork spring 10, the heavier rotation range that rotates post 11 of article is big more, and then makes limit hook 3 rotation range big more to guarantee that the fixed effect of article is better.

Please refer to fig. 2, the limiting mechanism includes a protecting cover 9, a rotating column 11 penetrating into the slot 2 is rotatably connected inside the protecting cover 9, a spring 10 is arranged at a position where the rotating column 11 contacts the protecting cover 9, a steel wire rope 7 is wound outside the rotating column 11, a fixing column 5 is arranged on both the front surface and the rear surface of the first plate 6, and the fixing column 5 is fixedly connected with the steel wire rope 7;

this fixed knot that civil engineering lift used constructs through the stop gear who sets up, accomplishes wire rope 7's rolling, and then ensures the rotation of rotating the post 11, accomplishes the fixed effect of spacing hook 3 to article.

Please refer to fig. 1, one end of the limit hook 3 is located inside the slot 2, the end of the rotation column 11 is fixedly connected with the limit hook 3, the inner walls of the limit hook 3 and the hook 1 are both provided with a protection pad, and the cross sections of the hook 1 and the limit hook 3 are both arc-shaped;

this fixed knot that civil engineering lift used constructs mutually supports with slot 2 through spacing hook 3 that sets up, and the spacing hook 3 of being convenient for is rotatory to mutually support with couple 1, accomplishes the spacing fixed to article, sets the cross section of couple 1 and spacing hook 3 into the arc, and then is convenient for rotate and reduces the distance between it, and then accomplishes fixedly.

Please refer to fig. 1, a tension spring 4 is disposed on one side of the second plate 8, and the end of the tension spring 4 is fixedly connected to the limit hook 3;

this fixed knot that civil engineering lift used constructs 3 upwards rotations of pulling limit hook through the tension spring 4 that sets up of being convenient for, when not having article hook, accomplish opening of couple 1, make things convenient for daily operation.

The working principle is as follows: firstly, the device is arranged on a hoisting machine, when an article needs to be hoisted, the device is moved to a position right above the article, the hook 1 hooks the article, the hoisting machine gradually pulls the article, meanwhile, the hook 1 is gradually stressed, the second plate body 8 is pulled to gradually leave the first plate body 6, at the moment, the rotating column 11 gradually rotates to drive the steel wire rope to loosen, meanwhile, the spring 10 and the reset spring 12 are gradually stressed to prevent the relative displacement between the first plate body 6 and the second plate body 8, meanwhile, the rotating column 11 drives the limiting hook 3 to rotate to gradually enter the inside of the slot 2 to fix the article, when the article is heavier, the relative displacement between the first plate body 6 and the second plate body 8 is larger, the rotating amplitude of the rotating column 11 is larger, the relative distance between the limiting hook 3 and the hook 1 is smaller, the fixing effect on the article is better, when the article moves to a proper position, the hook 1 does not bear force, under the action of the reset spring 12, the clockwork spring 10 and the tension spring 4, the limiting hook 3 is gradually far away from the hook 1, so that the articles can be conveniently separated from the fixing mechanism.
