Description

Technical Field

[0001] The invention relates to the technical field of cranes, in particular to a ring-suspended double-beam crane. Background Art

[0002] The circular suspended double-beam crane is a special type of crane. It is mainly composed of a circular track, a double-beam structure, a lifting mechanism, a trolley running mechanism and a cart traveling mechanism. It is installed in a suspended manner. Its running track is circular, and the double-beam structure is used to carry the lifting mechanism and the trolley, which can efficiently carry out material lifting work in the circular area.

[0003] For example, the "A Circular Suspended Double-Girder Crane" with the publication number CN102992201A includes two circular end beams, a trolley suspended on the two circular end beams, a first beam frame for fixing the trolley, a main beam installed on the first beam frame, a trolley suspended on the main beam, a secondary beam frame arranged on the trolley, and an electric hoist suspended on the secondary beam frame. The trolley can move along the circumference of the two circular end beams, the trolley can move along the length direction of the main beam, and the electric hoist can move along the length direction of the secondary beam frame. Since the trolley is suspended on the two circular end beams, the trolley is suspended on the main beam of the trolley, and the electric hoist is suspended on the first beam frame of the trolley, the trolley can move along the circumference of the two circular end beams, the trolley can move along the length direction of the main beam, and the electric hoist can move along the length direction of the secondary beam frame. The structure of the present invention has the advantages of smooth start-up, precise positioning, reliable operation, reasonable design, safety and stability, etc.

[0004] However, in the prior art, although this type of annular suspension double-beam crane has the advantages of smooth starting, accurate positioning, reliable operation, reasonable design, safety and stability, it is lacking in preventing the hoisted object from shaking. Since this type of annular suspension double-beam crane lifts and moves the hoisted object through structures such as a trolley, a small car and an electric hoist, and the object shakes due to inertia during the movement, when the hoisted object shakes, the object may become unhooked, and the unhooking of the object will not only cause damage to the object, but also cause injuries to the staff, increasing the probability of safety accidents.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When in use, motor A drives gear A to rotate, and gear A will drive gear C to rotate through the tooth chain when rotating, and will also drive limit gear B to rotate, and gear C will drive gear D to rotate when rotating, and gear D will drive the side block, beam A and beam B to rotate on the top surface of the annular frame through the engagement with the annular tooth groove A. At this time, gear D will drive the limit block to roll inside the annular limit groove B, and the side block will also drive the limit roller A to roll inside the annular limit groove A, thereby completing the rotation of beam A and beam B. The diameter of gear A is much smaller than that of gear C and gear D. When gear A is subjected to the force of motor A rotation, it will transmit the rotation to gear C through the tooth chain, and then gear C will transmit its force to gear D, and finally drive beam A and beam B through the engagement of gear D with the annular tooth groove A. Rotate, thereby realize the slow and smooth rotation of beam A and beam B, avoid the shaking of the lifted object due to inertia, and then drive gear G to rotate through motor B, gear B will drive gear F to rotate, and gear F will drive gear E to rotate when rotating, and gear E will drive connecting block A to move inside beam A and beam B through meshing with tooth groove B, at this time, connecting block A will drive limiting roller B to roll inside limiting groove C, and connecting block A will also drive moving block to move on the bottom surface of beam A and beam B, thereby realizing horizontal movement of the lifted object, the diameter of gear G is much smaller than gear F, and the rotation force of motor B is transmitted to gear E through gear G and gear F, thereby realizing slow horizontal movement of moving block, and further realizing the prevention of shaking of object due to inertia when moving the lifted object;

[0019] 2. When in use, the winding roller is driven to rotate by the motor C. When the winding roller rotates, the wire rope is wound in the winding roller. The contraction of the wire rope drives the connecting block B to move upward, thereby driving the lifting object to move upward through the hook. After the lifting object is hung on the hook, the push block is driven to move by the electric push rod. When the push block moves, it drives the rotating frame to rotate on the surface of the connecting block B, thereby driving the fixed rod to move. After the fixed rod moves into the slot, the hook can be closed. The movable design of the fixed rod has the effect of closing the hook, thereby preventing the lifting object from being unhooked due to its shaking during the lifting or moving process. At the same time, the electric opening and closing method of the fixed rod also facilitates the staff to install the lifting object on the hook and remove the lifting object from the hook, which improves the installation and removal efficiency while ensuring the stability of the lifting object when it moves on the hook;

[0020] 3. When in use, the motor D is used to drive the screw to rotate, and the screw will drive the connecting block C to move inside the support column when rotating, and the connecting block C will drive the annular baffle to slide inside the limit groove D. The annular baffle will drive the bottom pad to move downward during the descent process, and the lifted object can be lifted and moved after the bottom pad fits the bottom surface. After the object is transferred, the annular baffle can be raised, thereby preventing the lifted object from falling due to the breakage of the wire rope or the failure of a mechanical component during the lifting process, which may cause casualties.

Rolling, at the same time, the connecting block A120 will also drive the moving block 117 to move on the bottom surface of the beam A103 and the beam B104, thereby realizing the horizontal movement of the lifted object. The diameter of the gear G125 is much smaller than that of the gear F123.

When the push block 210 moves, it will drive the rotating frame 208 to rotate on the surface of the connecting block B203, thereby driving the fixing rod 209 moves, and the hook 205 can be closed after the fixing rod 209 moves into the card slot 206. The movable design of the fixing rod 209 has the effect of closing the hook 205, thereby preventing the lifting object from being unhooked due to its shaking during the lifting or moving process. At the same time, the electric opening and closing method of the fixing rod 209 also facilitates the staff to install the lifting object on the hook 205 and remove the lifting object from the hook 205, thereby improving the installation and removal efficiency and ensuring the stability of the lifting object when moving on the hook 205.

The annular baffle 304 will drive the bottom pad 305 to move downward during the descent process. After the bottom pad 305 fits the bottom surface, the lifted object can be lifted and moved. After the object is transferred, the annular baffle 304 can be raised, thereby preventing the lifted object from falling due to the breakage of the wire rope 202 or the failure of a mechanical component during the lifting process, causing casualties.
