Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to an anti-sway crane. Background Art

[0002] In industry, metal parts need to be pickled to remove surface rust, and round steel rings are no exception. Round steel rings are made by spirally winding a steel column with a smaller cross-sectional diameter into a cylindrical shape. Due to its overall heavy weight, it needs to be carried by a mobile tool during pickling. Round steel rings are generally transported to the pickling tank by a forklift, and then need to be lifted by tools for pickling. At present, the lifting of round steel rings is generally carried out by electric hoists through wire ropes and hooks. However, the problem with this lifting structure is that the wire rope is a flexible structure, and the weight of the round steel ring is relatively large. Therefore, the round steel ring is easy to shake during the lifting process, posing a major safety hazard. Utility Model Content

[0005] After adopting the above structure, the utility model has the following advantages: the round steel ring is transported to the sling by a forklift, the round steel ring is put on the second connecting rod, the connecting frame, the connecting column and the sling are driven by the electric hoist to lift and lower together, and the driving mechanism drives the trolley to move on the beam bridge to realize the lifting of the round steel ring for pickling, and in the lifting process, the middle connecting frame and the columns on both sides are slidably connected by the first guide wheel, so that the connecting frame and the connecting column are not easy to shake during the lifting process, and the sling is rigidly connected as a whole, and is not easy to shake during the lifting process. Therefore, the round steel ring is not easy to shake during the lifting process, which greatly improves the safety and reduces the potential safety hazards.

[0006] As an improvement, a track is provided on each column and on the side wall close to the connecting frame along the height direction of the column, and a groove with a shape matching the track is provided in the middle part of each first guide wheel along the circumferential direction. The track is located in the groove and abuts against the inner wall of the groove. This structure makes the first guide wheel roll more stably along the column and further prevents shaking.

[0008] As an improvement, a mounting plate is connected between the two columns and the mounting plate is located at the lower part of the columns. A through hole is provided in the middle of the mounting plate for the connecting column to pass through. A buffer is connected to the top of the mounting plate and the buffer is located on the moving path of the connecting frame. With this structure, when the connecting frame moves downward to the extreme position, the buffer acts as a buffer for the connecting frame to prevent damage to the connecting frame.

[0009] As an improvement, a second guide wheel is rotatably connected to each upright column and the side wall facing the connecting column, and the second guide wheel abuts against the connecting column; adopting this structure further reduces the shaking of the connecting column.

[0010] As an improvement, a movable pulley is rotatably connected to the connecting frame, and the steel wire rope of the electric hoist is connected to the movable pulley.

[0011] As an improvement, the beam bridge is two parallel beams, including two horizontal sections and one vertical section.

Two U-shaped frames are connected to the top of the trolley, and wheels are rotatably connected to the two opposite inner walls of each U-shaped frame. A limiting part is provided on the circumferential direction of each wheel. The horizontal section located below is located in the U-shaped frame, and the wheel is rollingly connected to the top of the horizontal section located below, and the horizontal section located below is located between the two limiting parts. With this structure, the horizontal section located below is restricted between the two limiting parts, which can prevent the wheel from separating from the horizontal section to a certain extent.
