Description

Technical Field

[0001] The utility model relates to the field of charging crane equipment, in particular to a lifting and charging trolley. Background Art

[0002] my country's steel industry is an important pillar industry of the national economy. It plays an important role in economic construction, social development, fiscal and taxation, national defense construction, and stable employment, and has made important contributions to ensuring the sound and rapid development of the national economy. The charging crane is an indispensable handling equipment for the steelmaking process of modern steel enterprises. The traditional charging crane is equipped with a main and auxiliary lifting trolley on the main beam of the trolley. The main lifting trolley controls two hooks to lift the bucket, and the auxiliary lifting trolley controls one hook to control the bucket to overturn and guide the material. For some buckets that do not need to overturn, such as grab buckets for discharging materials at the bottom, four lifting points are usually set to improve stability. Then the auxiliary lifting trolley will be replaced by another main lifting trolley, but two main lifting trolleys are used to control the movement of the four lifting points. Once the two main lifting trolleys move out of sync, or there is a difference in the length of the wire rope unwinding, it will affect the stability of the lifting. Utility Model Content

[0022] Combined with Figure 1-3 The described lifting and loading trolley comprises a trolley frame 4 and a hanger 7 correspondingly located below the trolley frame 4. Travel wheels 11 are installed at the four corners of the lower frame surface of the trolley frame 4. The travel wheels 11 are controlled by a motor and can be moved and positioned along the main beam of the trolley; four hooks 9 are connected to the lower parts of the four corners of the hanger 7 for directly hooking the four lifting points of the bucket. According to needs, the upper ends of the hooks 9 are hinged to the hanger 7 to facilitate flexible hooking of the bucket. Four lifting points are provided on the upper parts of the four corners of the hanger 7. By adding the hanger 7 between the hopper and the lifting hopper, it is convenient to lift the bucket with the hook, and it can also improve the safety of lifting, reduce the shaking effect caused by the change in the length of individual steel wire ropes 10, and further improve the lifting stability performance; two same Axial double drums 1, a double-axis motor 3 is arranged between the two double drums 1, and the two output shafts of the double-axis motor 3 are respectively connected to the drum shafts of the two double drums 1. The double drum 1 is a drum that winds two rolls of steel wire rope on two sections of the drum and retracts and releases them synchronously. Four lifting points are driven to lift respectively by two double drums 1 on a small frame 4, and the two double drums 1 are controlled to rotate by the same double-axis motor 3, thereby ensuring the synchronization and stability of lifting and lowering; according to needs, the double-axis motor 3 and the two double drums 1 are respectively located on both sides of the center line of the length direction of the small frame 4, so that the layout is more balanced and reasonable, and the inner end of each double drum 1 is connected to the corresponding output shaft of the double-axis motor 3 through the reducer 2;

[0023] Two fixed pulley blocks 6 coaxial with the double drum 1 are provided on both sides of each double drum 1. After the outer ends of the two rolls of steel wire rope 10 wound on the double drum 1 pass around the two corresponding fixed pulley blocks 6 on both sides, they are correspondingly connected to the two lifting points at the corresponding ends of the hanger 7, that is, the double drum 1 at the end of the trolley frame 4 controls the two lifting points at the same end of the lifting hanger 7; according to needs, the lifting point of the hanger 7 is set to a movable pulley block 8 coaxial with the fixed pulley block 6, the outer end of the steel wire rope 10 of the double drum 1 passes around the lower part of the movable pulley block 8 below the fixed pulley block 6 on the corresponding side, and then passes upward around the upper part of the corresponding fixed pulley block 6 to form a lifting hoisting ring, and then is fixedly connected to the corresponding end of the hanger 7, and lifting with the movable pulley block 8 is more efficient and labor-saving.

[0024] To implement the lifting and feeding trolley of the utility model, after the trolley frame 4 is moved into position on the trolley crossbeam, it is only necessary to control the dual-axis motor 3 to rotate and drive the two double-linked drums 1, so that the hanger 7 can be synchronously controlled to descend through the wire rope 10. After the four hooks 9 of the hanger 7 are hooked on the hopper, the hanger 7 can be controlled to rise to carry out subsequent lifting work. Embodiment 2:

[0025] As attached Figure 4-6 As shown, the difference from the first embodiment is that the fixed pulley block 6 and the movable pulley block 8 are each provided with two pulley bodies spaced apart and arranged side by side, and the corresponding steel wire rope 10 is sequentially wound around the four pulley bodies to form two lifting rings, as shown in the attached Figure 6 As shown, the two steel wire ropes 10 on the double drum 1 extend downward to the left and right respectively, bypass a pulley body of the movable pulley group 8, bypass a pulley body of the fixed pulley group 6 upward, and then bypass the other pulley body of the movable pulley group 8 downward, and then bypass the other pulley body of the fixed pulley group 6 upward, forming two lifting circles to ensure that lifting is more labor-saving; according to needs, balance arms 5 are provided at both ends of the upper surface of the hanger 7, and hinge seats 12 are fixed at the center of both ends of the upper surface of the hanger 7. The middle part of the balance arm 5 and the hinge seat 12 are correspondingly hinged through a hinge shaft. After the outer ends of the two rolled steel wire ropes 10 of the double drum 1 are wound through the two lifting circles, they are fixedly connected to the two ends of the balance arm 5 at the corresponding ends of the hanger 7. In this way, when a steel wire rope 10 changes length unexpectedly, the balance arm 5 can be used for adaptive adjustment.
