Description

Technical Field

[0001] This utility model relates to the field of metal heat treatment technology, specifically to a workpiece hoisting system for heat treatment. Background Technology

[0002] Metal heat treatment is a process in which metal workpieces are heated to a suitable temperature in a certain medium, held at that temperature for a certain time, and then cooled at different rates in different media. By changing the microstructure of the surface or interior of the metal material, its properties can be controlled. When heat treating metals, a workpiece hoisting system is needed to transport the metal workpieces to the heat treatment furnace for heating.

[0003] The published patent document CN208994949U discloses a heat-treated workpiece hoisting system. Compared with the prior art, the heat-treated workpiece hoisting system provided by this utility model has a detachable connection between the sling and the load-bearing plate. After the workpiece is hoisted into the heat treatment furnace, the operator can separate the sling from the workpiece without the need for auxiliary tools. This is simple, quick, avoids high-temperature working time, and ensures the health of the operator. However, the aforementioned patent document only facilitates the disassembly between the sling and the load-bearing plate. When it is necessary to remove the heat-treated metal workpiece from the heat treatment furnace, it is not convenient to quickly install the sling and the load-bearing plate, which makes it impossible to quickly transport the heat-treated metal workpiece out of the heat treatment furnace, making it inconvenient to use.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-4This utility model provides a workpiece hoisting system for heat treatment, including a load-bearing frame 1 and a hanger 2. Four uprights 3 are fixedly installed on the top of the load-bearing frame 1, and the uprights 3 are provided with insertion holes 16. Four rotating shafts 9 and four adjusting blocks 10 are provided below the hanger 2. One end of the rotating shaft 9 is fixedly connected to a lead screw 11, and the other end of the rotating shaft 9 is fixedly connected to a bevel gear 14. The middle of the adjusting block 10 is provided with a threaded hole 18 that matches the lead screw 11, and one side of the adjusting block 10 is fixedly connected to an insertion shaft 17 that matches the insertion hole 16. A servo motor 5 is fixedly installed in the middle of the top of the hanger 2. A drive shaft 12 is fixedly installed at the output end of the servo motor 5. A bevel gear 13 is fixedly connected to the lower end of the drive shaft 12. The bevel gear 13 is meshed with all four bevel gears 14.

[0028] In this technical solution, the servo motor 5 drives the drive shaft 12 to rotate. The drive shaft 12 drives the four rotating shafts 9 to rotate synchronously through the first bevel gear 13 and four second bevel gears 14. The rotating shafts 9 drive the adjusting block 10 to move through the lead screw 11 and the threaded hole 18. The adjusting block 10 drives the insertion shaft 17 to move, so that the insertion shaft 17 can be inserted into or removed from the insertion hole 16. This facilitates the quick installation and disassembly between the load-bearing frame 1 and the hanger 2, and makes it convenient to transport heat-treated metal into and out of the heat treatment furnace. It is relatively convenient to use.

[0029] In some technical solutions, such as Figure 1-2 As shown, several metal placement boxes 4 are fixedly installed at equal intervals inside the load-bearing frame 1.

[0030] In use, multiple heat-treated metals can be classified and separated at the same time through the multiple metal placement boxes 4 inside the load-bearing frame 1, preventing contamination from contact between the heat-treated metals.

[0031] In some technical solutions, such as Figure 3 As shown, a number of auxiliary parts 15 are sleeved on the rotating shaft 9. The auxiliary parts 15 are connected to the rotating shaft 9 through bearings, and the top of the auxiliary parts 15 is fixedly installed to the bottom of the hanger 2.

[0032] During use, the auxiliary component 15 ensures the stability of the rotation of the shaft 9.

[0033] In some technical solutions, such as Figure 4 As shown, two U-shaped parts 19 are fixedly connected at the four positions of the bottom of the hanger 2. A limiting shaft 20 is fixedly installed inside the U-shaped part 19. Sliding parts 21 are symmetrically fixedly connected on both sides of the adjusting block 10. The top of the sliding part 21 is inside the U-shaped part 19, and the limiting shaft 20 passes through the sliding part 21. The sliding part 21 is slidably connected to the limiting shaft 20.

[0034] In use, the U-shaped part 19 and the limiting shaft 20 limit the sliding part 21 to ensure the stability of the movement of the adjusting block 10.

[0035] In some technical solutions, such as Figure 1-2 As shown, a support member 6 is provided above the hanger 2, and a lifting ring 7 is fixedly connected to the top of the support member 6.

[0036] In use, the lifting system can be easily connected to the lifting equipment via the lifting ring 7 on the support member 6.

[0037] In some technical solutions, such as Figure 1 As shown, support shafts 8 are fixedly connected to the four corners of the bottom of the support member 6, and the lower end of the support shafts 8 is fixedly installed to the top of the hanger 2.

[0038] In use, the stability between the support member 6 and the hanger 2 is ensured by the four support shafts 8 between the support member 6 and the hanger 2.

[0039] Working principle: During use, the hook of the hoisting equipment is first connected to the lifting ring 7, and the hanger 2 is hoisted to the top of the load-bearing frame 1. The servo motor 5 drives the drive shaft 12 to rotate. The drive shaft 12 drives the four rotating shafts 9 to rotate synchronously through the first bevel gear 13 and four second bevel gears 14. The rotating shafts 9 drive the adjusting block 10 to move through the lead screw 11 and the threaded hole 18. The adjusting block 10 drives the insertion shaft 17 to move, so that the insertion shaft 17 can be inserted into or removed from the insertion hole 16, which facilitates the quick installation and disassembly between the load-bearing frame 1 and the hanger 2, thereby facilitating the transport of heat-treated metal to and from the heat-treated furnace. The multiple metal placement boxes 4 inside the load-bearing frame 1 can classify and separate multiple heat-treated metals at the same time.
