At this time, the staff can directly cut the steel bar binding ropes.

[0028] The hoisting mechanism 14 includes a motor 2 401, a mounting frame 1 402, a rope 1 403 and a hook 404. A mounting frame 1 402 is fixedly arranged above the connecting ring 3, a reel 1 is installed in the mounting frame 1 402, a rope 1 403 is wound around the reel 1, a motor 2 401 is arranged on one side of the mounting frame 1 402, a transmission shaft of the motor 2 401 is coaxially fixed with one end of the reel 1, and the other end of the reel 1 is connected to the bearing of the mounting frame 1 402, and a through hole penetrating the fixed arm 1 is provided in the fixed arm 1, and the through hole is located below the mounting frame 1 402 fixedly connected to the fixed arm 1 The telescopic arm 2 is provided with a through hole penetrating the telescopic arm 2, and the through hole is located below a mounting frame 402 fixedly connected to the telescopic arm 2. The telescopic arm 2 is also provided with a through slot 201 penetrating the telescopic arm 2, and the through slot 201 is communicated with a through hole provided in the fixed arm 1. One end of a rope 403 wound on a reel above the fixed arm 1 passes through the through hole provided in the fixed arm 1 and the through slot 201 and is connected to a hook 404 located below the fixed arm 1. One end of a rope 403 wound on a reel above the telescopic arm 2 passes through the through hole provided in the telescopic arm 2 and is connected to a hook 404 below the telescopic arm 2.

[0029] When the hoisting mechanism 4 is working, the staff first drives the motor 2 401 to drive the reel 1 to rotate, releases the rope 1 403 to make the hook 404 descend, and the staff manually hangs the hook 404 on the steel bar binding rope, and then drives the motor to drive the reel 1 to reverse, retracts the rope 1 403 to make the hook 404 rise with the steel bar, and controls the clamping mechanism 5 to work to grab the steel bar when the steel bar rises.

[0030] The gripping mechanism 5 includes a cylinder 501, a connecting block 502, a suspension arm 1 503, a suspension arm 2 504, a fixing plate 505 and a connecting shaft 506.

The top end of the cylinder 501 is hinged to the connecting seat 301, and the connecting seat 301 is fixedly connected to the connecting ring 3.

[0031] When the steel bar moves upward driven by the hook 404, the staff drives the two cylinders 501 of the clamping mechanism 5 to shorten the telescopic rod 5011, and the lower ends of the boom 1 503 and the boom 2 504 move away from each other. The hook 404 drives the steel bar to enter between the boom 1 503 and the boom 2 504. The staff drives the cylinder 501 to extend the telescopic rod 5011 and bring the lower ends of the boom 1 503 and the boom 2 504 closer to confine the steel bar in the space formed by the boom 1 503 and the boom 2 504. Then the staff can cut the steel bar binding rope.

[0032] A motor 6 is arranged above the fixed arm 1, a gear 7 is arranged inside the fixed arm 1, the motor 6 passes through the top plate of the fixed arm 1 and is coaxially fixed with the gear 7, the ends of the telescopic arms 2 close to each other are located inside the fixed arm 1, and racks 8 are fixedly arranged at the ends of the telescopic arms 2 close to each other, the racks 8 are located on both sides of the gear 7 and are meshed with the gear 7;

[0033] Due to the different lengths of the steel bars, the positions of the steel bar binding ropes are also different. The staff controls the extension and contraction of the telescopic arm 2 according to the situation, thereby controlling the distance between the hoisting mechanism 4 and the grabbing mechanism set at one end of the telescopic arm 2 that are away from each other. The staff drives the motor 6 to drive the gear 7 to rotate, and the gear 7 is engaged with the rack 8. The rotation of the gear 7 drives the rack 8 to move closer or farther away from each other, thereby controlling the telescopic arm 2 to move closer or farther away from each other.

[0034] A telescopic arm 9 for a traveling crane is fixedly arranged on the top surface of the fixed arm 1, and both ends of the telescopic arm 9 for a traveling crane are connected. The top end of the telescopic arm 9 for a traveling crane passes through the bottom end of the fixed arm 11 for a traveling crane, and both ends of the fixed arm 11 for a traveling crane are connected. The side walls of the telescopic arm 9 for a traveling crane are provided with only a square through hole 1901, and a fixed shaft 1 and a roller 10 are arranged in the square through hole 1901. The roller 10 is penetrated by the fixed shaft 1 and is rotatably connected to the roller 10, and the roller 10 is fitted with the inner wall of the fixed arm 11 for a traveling crane, and the side walls of the fixed arm 11 for a traveling crane are provided with a square through hole 2 1101, and a fixed shaft 2 and a roller 2 12 are arranged in the square through hole 2 1101. The fixed shaft 2 passes through the roller 2 12 and is rotatably connected to the roller 2 12, and the roller 2 12 is fitted with the outer side wall of the telescopic arm 9 for a traveling crane, and the fixed arm 11 for a traveling crane is provided with a square through hole 2 A hoisting mechanism 2 13 is provided above the fixed arm 11, and the hoisting mechanism 2 13 is installed on the upper frame 14 of the traveling crane, and the upper frame 14 of the traveling crane is fixedly connected to the fixed arm 11 of the traveling crane, and the hoisting mechanism 2 13 includes a mounting frame 2 1301, a motor 3 1302 and a rope 2 1303, and the mounting frame 2 1301 is fixed on the upper frame 14 of the traveling crane, and a motor 3 1302 is provided on the side of the mounting frame 2 1301, and a reel 2 is installed on the mounting frame 2 1301, and a rope 2 1303 is wound around the reel 2, and the transmission shaft of the motor 3 1302 is coaxially fixed with one end of the reel 2, and the other end of the motor 3 1302 is connected to the bearing of the mounting frame 2 1301, and one end of the mounting frame 2 1301 passes through the fixed arm 11 of the traveling crane and the telescopic arm 9 of the traveling crane and is fixedly connected to the top of the fixed arm 1;

[0035] The hoisting mechanism 2 13 drives the fixed arm 1 and the telescopic arm 2 to move to a position close to the steel bar, and then controls the hoisting mechanism 1 4 to send the steel bar into the space formed by the suspension arm 1 503 and the suspension arm 2 504. When the hoisting mechanism 2 13 is working, it drives the motor 3 1302, and the motor 3 1302 drives the reel 2 to rotate and release the rope 2 1303. Under the action of gravity, the telescopic arm 9 of the crane moves downward with the fixed arm 1 and the telescopic arm 2, so that the hoisting mechanism 1 4 is close to the steel bar. After the clamping mechanism 5 grabs the steel bar, the staff drives the motor 3 1302 to reverse the reel 2. , rope 2 1303 is recovered, and the crane telescopic arm 9 moves upward with the fixed arm 1 and the telescopic arm 2, and the roller 10 is in contact with the inner wall of the crane fixed arm 11, and the roller 2 12 is in contact with the outer wall of the crane telescopic arm 9, and the roller 10 and the roller 2 12 assist the crane telescopic arm 9 to move in the crane fixed arm 11, thereby reducing the contact area between the crane telescopic arm 9 and the crane fixed arm 11, changing the sliding friction into the rolling friction, reducing the wear of the crane telescopic arm 9 on the crane fixed arm 11, and increasing the service life of the crane telescopic arm 9 on the crane fixed arm 11.

[0036] After the gripping mechanism 5 of the steel bar crane hoist finishes gripping the steel bar, the distance between the bottom ends of the boom 1 503 and the boom 2 504 is less than 10 mm, and the steel bar crane hoist is sufficient to grip steel bars with a diameter greater than or equal to 10 mm, and the telescopic arm 2 of the steel bar crane hoist is fully extended to lift steel bars with a length of 12 m. Since steel bars with a length of 12 m and a diameter of only 10 mm are too slender and difficult to handle, the steel bar crane hoist is sufficient to lift steel bars with a length of 12 m and a diameter of only 10 mm.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
