Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a bridge crane. Background Art

[0002] Bridge crane, also known as beam crane or overhead crane, is a kind of lifting machinery widely used in industrial field. It is favored for its high efficiency, flexible working performance and wide range of applications. Bridge crane is mainly composed of four parts: bridge, trolley running mechanism, trolley and electrical control system. Its working principle is to move the trolley of the crane to the designated position through the trolley running mechanism and trolley track, and then lift the heavy objects to the designated position or unload them through the trolley and lifting mechanism. During the lifting process, the movement trajectories of the trolley and the trolley are on the track, which ensures the stability and safety of the crane. The trolley consists of an electric hoist and a hook, which is suspended on the bridge. The electric hoist can lift and lower the hook vertically and move the hook horizontally to realize the lifting and handling of heavy objects. Since the lifting process of objects is mainly connected to the hook through the bundled wire rope, it is necessary to perform a stable lifting connection operation on the wire rope.

[0003] In the related art, during the use of a bridge crane, a closable anti-fall hook is generally used to stabilize the lifting connection between the wire rope connected to the object and the hook, thereby ensuring the stability of the connection between the wire rope and the hook, so that the crane can be used.

[0004] However, during the current use of bridge cranes, since the contact position between the wire rope and the hook is for stable connection, when the left and right weights of the objects are deviated during the lifting process, the hook will swing to a certain extent during operation, causing the wire rope to be affected by the left and right weights of the objects. The wire rope is prone to sliding inside the lifting ring, or even sudden excessive movement, causing the objects to tilt and swing more, resulting in lifting accidents and affecting the stability and safety of the crane's lifting connection.

[0036] Specifically, the working process or working principle of this bridge crane is as follows: when in use, first rotate the bolt 15 to disengage the screw groove 16 and the screw barrel 17, then hold the movable plate 5 and move it to the front side to open the spacing distance between the movable plate 5 and the fixed plate 4 to the maximum state. At this time, the mounting bar 11 moves inside the mounting port 10 to perform a movable connection between the movable plate 5 and the fixed plate 4. At the same time, the connecting seat 13 follows the movable plate 5 to move inside the connecting groove 12, and performs a movable connection and anti-separation work between the movable plate 5 and the fixed plate 4 through the mounting bar 11, and performs a magnetic positioning work between the moved movable plate 5 and the fixed plate 4, and then holds the fixed plate 4 by The mounting strip 11 drives the movable plate 5 to move to the top of the hook 3 and moves downward so that the hook 3 is located between the movable plate 5 and the fixed plate 4. At this time, the bottom of the mounting strip 11 contacts the top of the hook 3, providing a fulcrum for the fixed plate 4 and the movable plate 5 to contact the hook 3. Subsequently, according to the actual thickness of the hook 3, the movable plate 5 and the fixed plate 4 are moved toward the hook 3 by hand, so that the movable plate 5 contacts the surface of the inner hook 3 of the fixed plate 4. Then, the bolt 15 is held by hand and passes through the movable plate 5 through the connecting hole 14, and the bolt 15 is rotated to enter the screw groove 16 and the screw barrel 17 to connect and fix the movable plate 5 and the fixed plate 4 so that the fixed plate 4 cooperates with the movable plate 5 to clamp After the lifting ring is opened, the lifting bracket 19 is lifted and lowered, and the lifting bracket 19 is lowered to the bottom of the lifting ring 11. After the lifting bracket 19 is lifted and lowered, the lifting bracket 19 is lowered and lowered to the bottom of the lifting ring 11. After the lifting bracket 19 is lifted and lowered, the lifting bracket 19 is lifted and lowered to the bottom of the lifting ring 11. After the lifting bracket 19 is lifted and lowered, the lifting bracket 19 is lifted and lowered to the bottom of the lifting ring 11. After the lifting bracket 19 is lifted and lowered, the lifting bracket 19 is lifted and lowered to the bottom of the lifting ring 11. After the lifting bracket 19 is lifted and lowered, the lifting bracket 19 is lifted and lowered to the bottom of the lifting ring 11. During the lifting operation, first hold the wire rope connected to the object and enter the inside of the hook 3, and make the wire rope enter between the stabilizing frame 6 and the stabilizing plate 7, then hold the screw 9 and rotate it with the screw hole 8 to apply a downward thrust to the stabilizing plate 7. At this time, the swivel seat 26 follows the screw 9 to rotate inside the rotating groove 25, and performs a rotational connection between the screw 9 and the stabilizing plate 7. At the same time, the slide 24 follows the stabilizing plate 7 to move downward inside the slide groove 23, and performs a sliding connection between the stabilizing plate 7 and the stabilizing frame 6 during the movement, so that the stabilizing plate 7 moves downward stably and cooperates with the stabilizing frame 6 to perform lifting connection clamping and stabilization work on the wire rope, thereby ensuring the stability of the wire rope after being connected to the hook 3.
