Description

Technical Field

[0001] The utility model relates to the technical field of painting equipment, in particular to a workpiece hoisting device for a painting production line. Background Art

[0002] With the continuous development of society and the continuous progress of technology, the technology related to mechanical equipment is also constantly improving. The working characteristic of lifting equipment is intermittent movement, that is, in a working cycle, the corresponding mechanisms such as material taking, transporting, and unloading work alternately. The development and use of cranes in the market are becoming more and more extensive.

[0003] At present, for the workpiece hoisting device used in the painting production line, when quickly hoisting the workpiece, it is necessary to first hang the hanging ring on the lifting ring, and then thread the connecting screw rod with the connecting screw hole on the auxiliary ring. After long-term use, the connecting screw rod and the connecting screw hole are prone to thread slipping, which is not conducive to the hoisting of the workpiece. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following disadvantages in the prior art, and to propose a workpiece hoisting device for a painting production line.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A workpiece hoisting device for a painting production line includes a hook, a fixed frame, a turntable, a plurality of connecting screw rods, a hanging ring and an auxiliary ring. One end of each connecting screw rod is fixedly connected with a fixed frame, and the cross-section of the fixed frame is in a shape of a Chinese character 'hui'. The auxiliary ring and the hanging ring are rotationally connected. Two ear plates are installed on the auxiliary ring, and the two ear plates are connected by two reinforcing rods. A sliding rod is arranged on one of the ear plates, and a limiting block is fixedly connected to one end of the sliding rod. Arc-shaped grooves for connecting the limiting blocks are formed on the upper and lower inner surfaces of each fixed frame. A limiting component is arranged on each reinforcing rod. The limiting component includes a limiting shaft slidably arranged on the reinforcing rod. One end of the limiting shaft is clamped with the sliding rod. A chute is formed on each reinforcing rod, and one end of the limiting shaft is slidably connected with the chute. A spring is fixedly connected to one inner wall of each chute, and the spring is fixedly connected with the corresponding limiting shaft. Two round rods are fixedly connected to one side surface of one of the ear plates, and the end surface of each round rod is attached to the surface of the sliding rod. The cross-section of the sliding rod is in a T shape.

[0007] In order to better achieve the above purpose, the utility model adopts a further technical scheme: each ear plate is connected to the auxiliary ring by bolts, and threaded grooves are formed on both side surfaces of the auxiliary ring.

[0008] To better achieve the above object, the utility model adopts the following further technical solution: a moving groove is formed on the inner surface of the hanging ring, and a sliding block is fixedly connected to one side surface of the auxiliary ring, and the sliding block is slidably connected to the moving groove.

[0009] The advantages of the utility model are as follows: after the two ends of the limiting block are respectively clamped inside the two arc-shaped grooves, the external forces applied to the two limiting shafts are removed. Under the elastic force of the two springs, the distance between the two limiting shafts becomes smaller until one end of each limiting shaft is clamped with the clamping groove on the sliding rod, which can prevent the fixed frame from separating from the sliding rod, realize the quick connection of the connecting screw and the auxiliary ring, and there will be no thread slipping phenomenon after long-term use, which is beneficial to the hoisting of workpieces.

Detailed Embodiment

[0015] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model.

[0016] Refer to Figures 1-4As shown in the figure, a workpiece hoisting device for a painting production line includes a hook, a fixed frame 1, a turntable 2, a plurality of connecting screws 3, a lifting ring 5 and a secondary ring 6. One end of each connecting screw 3 is fixedly connected with a fixed frame 10. The cross-section of the fixed frame 10 is in a shape of a double-square frame. The secondary ring 6 is rotatably connected with the lifting ring 5. Two ear plates 8 are installed on the secondary ring 6. The two ear plates 8 are connected by two reinforcing rods 4. A sliding rod 7 is arranged on one of the ear plates 8. One end of the sliding rod 7 is fixedly connected with a limiting block 14. Arc-shaped grooves 15 for connecting the limiting block 14 are formed on the upper and lower inner surfaces of each fixed frame 10. A limiting component is arranged on each reinforcing rod 4. The limiting component includes a limiting shaft 9 slidably arranged on the reinforcing rod 4. One end of the limiting shaft 9 is clamped with the sliding rod 7. A sliding groove 16 is formed on each reinforcing rod 4. One end of the limiting shaft 9 is slidably connected with the sliding groove 16. A spring 17 is fixedly connected to the inner wall of one side of each sliding groove 16. The spring 17 is fixedly connected with the corresponding limiting shaft 9. When the external force applied to the two limiting shafts 9 is removed, under the elastic force of the two springs 17, the distance between the two limiting shafts 9 becomes smaller until one end of each limiting shaft 9 is clamped with the clamping groove on the sliding rod 7. At this time, the sliding rod 7 cannot move relative to the ear plate 8. Two round rods 13 are fixedly connected to the surface of one side of one of the ear plates 8. The end surface of each round rod 13 is attached to the surface of the sliding rod 7. The cross-section of the sliding rod 7 is in a T shape. Push the sliding rod 7 until the end surface of the round rod 13 is attached to the surface of the sliding rod 7. At this time, the sliding rod 7 cannot continue to extend into the fixed frame 10, and the limiting block 14 will extend into the fixed frame 10. At this time, the limiting block 14 is in a horizontal state and is located between the two arc-shaped grooves 15.

[0017] Each ear plate 8 is connected to the secondary ring 6 by bolts 11. Threaded grooves are formed on both side surfaces of the secondary ring 6. One end of each bolt 11 with a T-shaped cross-section penetrates through the corresponding ear plate 8 and is threadedly connected to the corresponding threaded groove, so that the two ear plates 8 can be firmly connected to the secondary ring 6.

[0018] A moving groove 12 is formed on the inner surface of the lifting ring 5. A sliding block is fixedly connected to the surface of one side of the secondary ring 6. The sliding block is slidably connected to the moving groove 12. When the secondary ring 6 rotates relative to the lifting ring 5, the sliding block will slide along the moving groove 12 at the same time, and the lifting ring 5 and the secondary ring 6 cannot be separated.

[0019] When the utility model is in use, the lifting ring 5 is placed directly below the fixed frame 10. At this time, the two ear plates 8 are respectively located on the front and rear sides of the fixed frame 10. Then, the two limiting shafts 9 are pulled to increase the distance between the two limiting shafts 9. Next, the sliding rod 7 is pushed until the end face of the round rod 13 is in contact with the surface of the sliding rod 7. After the sliding rod 7 and the ear plate 8 slide relative to each other, the limiting block 14 will extend into the interior of the fixed frame 10, and the limiting block 14 is in a horizontal state and located between the two arc-shaped grooves 15. Then, the sliding rod 7 is rotated, thereby driving the limiting block 14 to rotate together. After the limiting block 14 rotates, its two ends are respectively clamped in the two arc-shaped grooves 15. At this time, the external force applied to the two limiting shafts 9 is removed. Under the elastic force of the two springs 17, the distance between the two limiting shafts 9 becomes smaller until one end of each limiting shaft 9 is clamped with the clamping groove on the sliding rod 7, realizing the rapid connection of the connecting screw 3 and the auxiliary ring 6, and there will be no thread slipping phenomenon after long-term use, which is beneficial to the lifting of workpieces.
