Figure 1 The directions shown are consistent with the front, back, left, right, up and down directions of the device of the present invention when viewed from the front.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; they can refer to mechanical connection, direct connection, or indirect connection through an intermediate medium; they can refer to internal communication between at least two components or interaction between at least two components, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this invention can be understood according to specific circumstances.

[0025] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0026] Among them reference Figure 1 , Figure 1This is a preliminary design of a material frame connection device for a solid solution heat treatment furnace of the utility model, which includes a material frame 1, two lifting ears 10 and a connecting shaft. The material frame 1 is used to load a container for workpieces that need to be heat treated. The two lifting ears 10 are directly welded to both sides of the upper end surface of the material frame 1. The interior of the lifting ear 10 is hollow, and a hanging notch 11 is provided at the top. A hook suspension rod 17 is installed at the bottom of the connecting shaft, and a connecting head 24 is installed at the top for connection with a lifting device. The bottom of the hook suspension rod 17 is fixedly connected to a hook hanging plate 16. The hook The lifting rod 17 can slide into the lifting groove 11, and the upper end surface of the hook plate 16 will abut against the two side edges of the lifting groove 11, thereby forming a hook, and a fixing rod 20 is fixedly installed between the two connecting shafts. Since the connecting shaft is connected to the external lifting equipment and the connection is hinged, the entire connecting shaft can be shaken, which makes it convenient to lift the material frame 1. After the material frame 1 is hooked, in order to prevent the material frame 1 from shaking and rotating significantly, a fixing rod 20 is fixedly installed between the two connecting shafts.

[0027] We found that it has certain disadvantages during use. When the hook is hung, the hook plate 16 is directly slid into the ear 10. The resulting hook will still be displaced in the horizontal direction, resulting in an unstable connection with the material frame. Therefore, another embodiment of the utility model is proposed.

[0028] See also Figure 2-5 , including a material frame 1, two lifting ears 10 and a connecting shaft. The material frame 1 is used to load a container for workpieces that need to be heat treated. The two lifting ears 10 are respectively fixed to both sides of the upper end surface of the material frame 1 by bolts. The interior of the lifting ear 10 is hollow, and a hanging slot 11 is provided at the top. A hook hanging rod 17 is installed at the bottom of the connecting shaft. The bottom of the hook hanging rod 17 is fixedly connected to a hook hanging plate 16. The hook hanging rod 17 can slide into the hanging slot 11. At the same time, the upper end surface of the hook hanging plate 16 will abut against the two side edges of the hanging slot 11 to form a hook. A fixing rod 20 is fixedly installed between the two connecting shafts. Since the connecting shaft is connected to the external lifting equipment and the connection is hinged, the entire connecting shaft can be rocked, which makes it convenient to lift the material frame 1. After the material frame 1 is hooked, in order to prevent the material frame 1 from shaking and rotating significantly, a fixing rod 20 is fixedly installed between the two connecting shafts.

[0029] It is worth mentioning that in this embodiment, the connecting shaft includes a main shaft portion 19 and a sleeve portion 18, and a connecting head 24 is fixedly installed on the top of the main shaft portion 19, and the connecting head 24 is used to connect with the lifting equipment, and the sleeve portion 18 is fixedly installed at the lower end of the main shaft portion 19, and the interior of the sleeve portion 18 is hollow. The hook rod 17 is slidably connected in the sleeve portion 18, and an end portion 23 is provided at the top of the hook rod 17, and the end portion 23 can be stuck at the edge of the bottom of the sleeve portion 18, so that the up and down sliding distance of the hook rod 17 is the length of the internal space of the sleeve portion 18, and there is some friction when the end portion 23 slides in the internal space of the sleeve portion 18. When the hook plate 16 is not in contact with the lifting ear 10, the hook rod 17 is pushed upward, and the hook rod 17 will not fall off automatically.

[0030] It should be noted that in order to further improve the stability of the material frame when lifting, in this embodiment, the left and right ends of the fixed rod 20 are respectively provided with main stoppers 21, and the main stoppers 21 are provided with an annular portion 22. The sleeve portion 18 is fixedly installed in the annular portion 22. At the same time, a fixing plate 12 is fixedly installed on the end face of the lifting ear 10 on the side close to the center line direction of the fixed rod 20. Semicircular grooves 13 are evenly distributed on the bottom of the fixing plate 12. Two limit plates 14 are hinged to the lower end face of the fixed rod 20, and a limit block 15 is fixedly installed on the lower end face of each limit plate 14.

[0031] Before the material frame 1 is lifted, the hook rod 17 is retracted upward into the sleeve portion 18, and the hook plate 16 is exposed outside, so that the lifting equipment can be controlled to slide the hook plate 16 into the interior of the lifting ear 10, and at the same time, the hook rod 17 slides into the hanging groove 11, so that the upper end surface of the hook plate 16 abuts against the bottom two sides of the hanging groove 11. It should be noted that the upper end surface of the hook plate 16 is provided with a mesh friction pattern, which can greatly increase the friction during contact and hook the material frame 1. At the same time, the limit The block 15 also moves to the middle position along the fixed plate 12. Since the hook rod 17 is still partially retracted into the inner cavity of the sleeve portion 18 at this time, the limit block 15 does not come into contact with the bottom semicircular groove 13 of the fixed plate 12. Once the lifting equipment is driven to lift the material frame, the hook rod 17 is pulled downward due to the weight of the material frame 1, so that the arched protrusion on the upper end face of the limit block 15 is embedded in the corresponding semicircular groove 13, thereby forming an embedded limit, which further stabilizes the material frame and effectively prevents the material frame from slipping during the lifting process.

[0032] During the specific implementation, first connect the connecting head 24 to the mechanical arm of the lifting equipment, drive the mechanical arm, move the connecting shaft to the upper end of the material frame 1, move downward first, and make the lower end surface of the hook hanging plate 16 abut against the upper end surface of the lifting ear 10, so that the hook hanging rod 17 slides into the sleeve portion 18, and then move the mechanical arm to slide the hook hanging plate 16 into the interior of the lifting ear 10, and at the same time, the hook hanging rod 17 slides into the hanging groove 11, so that the upper end surface of the hook hanging plate 16 abuts against the bottom two sides of the hanging groove 11, and the material frame 1 is hooked. At the same time, the limit block 15 also moves to the middle position along the fixing plate 12. At this time, the hook Another section of the lifting rod 17 is retracted into the inner cavity of the sleeve portion 18, so the limit block 15 does not come into contact with the bottom semicircular groove 13 of the fixed plate 12. Once the lifting equipment is driven to lift the material frame, due to the weight of the material frame 1, the hook lifting rod 17 is pulled downward, so that the arched protrusion on the upper end face of the limit block 15 is embedded in the corresponding semicircular groove 13, thereby forming an embedded limit, further stabilizing the material frame, and thus smoothly lifting the material frame 1. The entire process does not require manual intervention and can achieve programmed automatic operation. Compared with traditional bent hook lifting, the stability of the hook is greatly improved, and there is no need for manual unhooking, which greatly improves the safety performance of workers.

[0033] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
