Description

Technical Field

[0001] This utility model belongs to the field of hanging equipment technology, specifically a lifting mechanism for a hanging production line. Background Technology

[0002] Patent No. 202420678074.X discloses a lifting arm for a hanging system, including an aluminum lifting arm. A belt is wrapped around the outer side of the aluminum lifting arm, and belt pushers are arranged laterally on the side of the belt. The belt pushers are distributed on the outside of the aluminum lifting arm and are arranged diagonally. A second guide rail support frame is arranged laterally on one side of the aluminum lifting arm, and a guide rail is arranged on one side of the second guide rail support frame. The guide rail is located on one side of the aluminum lifting arm. A clothes hanger guide wheel is movably mounted on the guide rail, and a clothes hanger is movably mounted on one side of the clothes hanger guide wheel. The belt pushers are parallel to the guide rail, and one end of the belt pusher contacts the bottom end of the clothes hanger guide wheel. When the belt pushers move along the side of the aluminum lifting arm via the belt, they drive the clothes hanger guide wheel to move upward on the guide rail, thereby lifting the clothes hanger or other carrier from a lower processing point to a relatively higher hanging exit.

[0003] The patent has certain defects. As the hanger guide wheel moves upward along the guide rail, the hanger will swing freely. When the hanger passes the bend of the second support frame, if the hanger collides with the bend, it will cause damage to the hanger and increase maintenance costs. If the hanger gets stuck at the bend, it will affect the normal transportation of the hanging assembly line. Summary of the Invention

[0004] This utility model addresses the aforementioned technical problems by providing a lifting mechanism for a suspended production line. A lifting protective block is installed at the bend of the second guide rail connecting plate to ensure transportation stability and improve transportation efficiency during the lifting process.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a lifting mechanism for suspending an assembly line includes a lifting arm installed on a frame, the lifting arm including a lifting motor and a lifting mounting base; a lifting guide rail is provided on one side of the lifting arm, the lifting guide rail has a horizontally arranged first guide section, an arc section and a vertically arranged second guide section; the first guide section is fixed to the bottom of the lifting mounting base by a first guide rail connecting plate, the second guide section is fixed to one side of the lifting mounting base by a second guide rail connecting plate, and a lifting protective block is provided at the bend of the second guide rail connecting plate.

[0006] To optimize the above technical solution, the present invention also includes the following improved technical solutions.

[0007] The aforementioned lifting protective block has a protective front plate and a protective side plate, and the second guide rail connecting plate has a second connecting front plate and a second connecting side plate; the inner side of the protective front plate is provided with a first latching part that cooperates with the second connecting front plate, the inner side of the protective side plate is provided with a second latching part that cooperates with the second connecting side plate, and the upper end of the protective front plate is provided with a third latching part that cooperates with the second connecting front plate.

[0008] The aforementioned lifting protective block has a downwardly extending lifting guide portion, the end of which abuts against the second guide section of the lifting guide rail; the lifting protective block has a fixing hole.

[0009] The aforementioned second guide section is fixed to one side of the lifting mounting base by multiple sets of second guide rail connecting plates, and the number of lifting protective blocks is the same as the number of second guide rail connecting plates.

[0010] The aforementioned lifting mounting base is installed at an angle on the frame, the lifting motor is installed at one end of the lifting mounting base, and the lifting mounting base is equipped with a lifting transmission assembly.

[0011] The aforementioned lifting transmission assembly includes a first synchronous pulley, a second synchronous pulley, and a first synchronous belt.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Figures 1 to 3 The diagram shown is a structural schematic of this utility model.

[0018] The attached figures are labeled as follows: lifting arm 1, lifting motor 2, lifting mounting base 3, first synchronous belt 4, push block 5, lifting guide rail 6, first guide section 6a, arc section 6b, second guide section 6c, first guide rail connecting plate 7, second guide rail connecting plate 8, second connecting front plate 8a, second connecting side plate 8b, lifting protective block 9, protective front plate 9a, protective side plate 9b, first buckle part 9c, first inclined surface 9d, second buckle part 9e, second inclined surface 9f, third buckle part 9g, third inclined surface 9h, lifting guide part 9i, fixing hole 9j, hanger wheel 10, hanger body 11, hanger rod 12.

[0019] This utility model discloses a lifting mechanism for a suspended production line, comprising a lifting arm 1 mounted on a frame, with a lifting guide rail 6 on one side of the lifting arm 1. One end of the lifting guide rail 6 is connected to the inlet guide rail of the suspended production line, and the other end of the lifting guide rail 6 is connected to the outlet guide rail of the suspended production line. The hanger wheels 10 of the hanging clothes hangers enter the lifting guide rail 6 along the inlet guide rail. The workbench processes the suspended materials, and after processing, the lifting arm 1 lifts the hanger wheels 10 on the lifting guide rail 6 upwards to the outlet guide rail.

[0020] The lifting arm 1 includes a lifting motor 2 and a lifting mounting base 3. The lifting mounting base 3 is mounted at an angle on the frame, and the lifting motor 2 is mounted at one end of the lifting mounting base 3. The lifting mounting base 3 is equipped with a lifting transmission assembly, through which the lifting motor 2 drives the hanger wheel 10 on the lifting guide rail 6 to move upward.

[0021] The lifting transmission assembly includes a first synchronous pulley, a second synchronous pulley, and a first synchronous belt 4. The first and second synchronous pulleys are mounted vertically on the lifting mounting base 3, with the first synchronous belt 4 sleeved on the first and second synchronous pulleys. The drive shaft of the lifting motor 2 is rotatably connected to the first synchronous pulley. Multiple sets of push blocks 5 for moving the hanger wheel 10 are evenly mounted on the outside of the first synchronous belt 4. The lifting motor 2 drives the first synchronous pulley to rotate, which in turn drives the first synchronous belt 4 to rotate. The push blocks 5 on the first synchronous belt 4 move with the first synchronous belt 4, thereby pushing the hanger wheel 10 to move. In this embodiment, the lifting transmission assembly uses a synchronous belt drive; a chain drive can also be used to achieve the same purpose.

[0022] The lifting guide rail 6 has a horizontally arranged first guide section 6a, an arc section 6b, and a vertically arranged second guide section 6c. The first guide section 6a and the second guide section 6c are connected by the arc section 6b. The end of the first guide section 6a is connected to the inbound guide rail, and the end of the second guide section 6c is connected to the outbound guide rail. The first guide section 6a is fixed to the bottom of the lifting mounting base 3 by a first guide rail connecting plate 7, and the second guide section 6c is fixed to one side of the lifting mounting base 3 by a second guide rail connecting plate 8. A lifting protective block 9 is provided at the bend of the second guide rail connecting plate 8, which serves both protective and guiding functions.

[0023] The lifting protective block 9 has a protective front plate 9a and a protective side plate 9b, and the second guide rail connecting plate 8 has a second connecting front plate 8a and a second connecting side plate 8b. The inner side of the protective front plate 9a has a first latching part 9c that mates with the second connecting front plate 8a. The first latching part 9c has a first inclined surface 9d, and the lower end of the second connecting front plate 8a engages with the first latching part 9c along the first inclined surface 9d. The inner side of the protective side plate 9b has a second latching part 9e that mates with the second connecting side plate 8b. The second latching part 9e has a second inclined surface 9f, and the lower end of the second connecting side plate 8b engages with the second latching part 9e along the second inclined surface 9f. The upper end of the protective front plate 9a has a third latching part 9g that mates with the second connecting front plate 8a. The third latching part 9g has a third inclined surface 9h, and the upper end of the second connecting front plate 8a engages with the third latching part 9g along the third inclined surface 9h.

[0024] The lifting protective block 9 has a downwardly extending lifting guide portion 9i, the end of which abuts against the second guide section 6c of the lifting guide rail 6. The lifting protective block 9 has a fixing hole 9j, through which screws can pass to fix the lifting protective block 9 to the outside of the second guide rail connecting plate 8, thereby strengthening the fixation.

[0025] The hanger body 11 of the hanging hanger is connected to a hanger rod 12 at one end, and the end of the hanger rod 12 is rotatably connected to the hanger wheel 10. When the hanger wheel 10 moves upward along the second guide section 6c of the lifting guide rail 6, the hanger body 11 will swing irregularly. When the hanger body 11 of the hanging hanger approaches the lifting protective block 9, the hanger body 11 continues to move upward along the lifting guide section 9i. The lifting protective block 9 covers the bend of the second guide rail connecting plate 8, avoiding the protruding corner of the bend of the second guide rail connecting plate 8, preventing the protruding corner from colliding with or getting stuck on the hanger body 11, and ensuring the stability of the hanging assembly line transportation.

[0026] In this embodiment, the second guide segment 6c is fixed to one side of the lifting mounting base 3 by two sets of second guide rail connecting plates 8, and therefore two sets of lifting protective blocks 9 are correspondingly provided. Depending on the different lengths of the second guide segment 6c in the lifting guide rail 6, the number of second guide rail connecting plates 8 can be appropriately adjusted, and the number of lifting protective blocks 9 is the same as the number of second guide rail connecting plates 8. The number of second guide rail connecting plates 8 can be one to four sets, and the corresponding number of lifting protective blocks 9 can be one to four sets.

[0027] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
