Description

Technical Field

[0001] This utility model belongs to the field of crane technology, and in particular relates to an intelligent trolley with four lifting points. Background Technology

[0002] In gantry cranes and bridge cranes, the wire rope winding system of the hoisting mechanism mostly uses a single lifting pulley block, which is equivalent to having only one lifting point in the wire rope winding system. It is difficult to ensure that the center of gravity of the load coincides with the center of the lifting pulley block in both the horizontal X and Y directions. The load is very prone to tilting during handling, which leads to instability of the hoisting system and easily causes accidents. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a four-point intelligent trolley, which effectively solves the problem of tilting when lifting loads.

[0004] The technical solution to the technical problem is as follows: It includes a trolley frame, on which a lifting mechanism is installed. Below the lifting mechanism is a lifting beam. The lifting mechanism includes a motor, a reducer, and a brake. Drums are coaxially mounted on both ends of the reducer, located in front of the motor. A first wire rope and a second wire rope are wound on the drums. A first pulley block corresponding to the first wire rope is installed on the lifting beam. A first balance bar and a second balance bar are fixed below the trolley frame. The first wire rope is longitudinally wound around the first pulley block, and the other end of the first wire rope is fixedly connected to the first balance bar. A guide wheel located in front of the drum is installed on the trolley frame. A second pulley block corresponding to the second wire rope is installed on the lifting beam. The second wire rope is transversely wound around the guide wheel and then longitudinally wound around the second pulley block via the guide wheel. The other end of the second wire rope is fixedly connected to the second balance bar.

[0005] Preferably, multiple anti-rail wheels are installed in the lower middle of the trolley frame.

[0006] Preferably, horizontal wheels are installed on the left and right sides of the trolley frame. This invention has the following advantages over traditional equipment: the unique wire rope winding method increases the spacing between suspension points and reduces the overall width of the machine, resulting in high balance and safety.

[0009] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0010] Depend on Figures 1 to 4 A four-point intelligent trolley is provided, comprising a trolley frame 1, a lifting mechanism mounted on the trolley frame 1, a lifting beam 2 below the lifting mechanism, the lifting mechanism including a motor 3, a reducer 4, and a brake 5, with drums 6 coaxially mounted at both ends of the reducer 4, the drums 6 being located in front of the motor 3, and a first wire rope 7 and a second wire rope 8 wound on the drums 6, a first pulley block 9 corresponding to the first wire rope 7 mounted on the lifting beam 2, and a first balance bar 10 fixed below the trolley frame 1. The second balance bar 11, the first wire rope 7 is longitudinally wound on the first pulley block 9, the other end of the first wire rope 7 is fixedly connected to the first balance bar 10, the trolley frame 1 is equipped with a guide wheel 12 located in front of the drum 6, the lifting beam 2 is equipped with a second pulley block 13 corresponding to the second wire rope 8, the second wire rope 8 is transversely wound on the guide wheel 12, and longitudinally wound on the second pulley block 13 via the guide wheel 12, the other end of the second wire rope 8 is fixedly connected to the second balance bar 11.

[0011] To prevent the trolley from tipping over, multiple anti-rail wheels 14 are installed in the lower middle of the trolley frame 1.

[0012] To prevent the trolley from veering off course, horizontal wheels 15 are installed on the left and right sides of the trolley frame 1.

[0013] In use, the lifting mechanism is arranged outside the track of the trolley frame 1. A reverse rail wheel 14 is added to the lower middle of the trolley frame 1 to prevent the trolley from tilting, and a horizontal wheel 15 is added to prevent the trolley from deviating, ensuring the positioning accuracy of the trolley. The drum 6 corresponds to the first pulley group 9 and the second pulley group 13. The first pulley group 9 and the second pulley group 13 are respectively installed at both ends of the lifting beam 2. The axes of the two drums 6 are on a straight line. Four steel wire ropes come down from the two drums 6 and are distributed on both sides of the main beam. The two first steel wire ropes 7 are longitudinally fixedly connected to the first balance bar 10 through the first pulley group 9. The two second steel wire ropes 8 are transversely fixedly connected to the second balance bar 11 through the guide wheel 12 and then longitudinally through the second pulley group 13. The four pulley groups are respectively connected to the four corners of the lifting beam 2, which increases the distance between the lifting points and reduces the overall width of the machine, making the crane run more smoothly.

[0014] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
