Description

Technical Field

[0002] A co-permeation furnace is a heat treatment device mainly used for the co-permeation process in chemical heat treatment. Co-permeation refers to a chemical heat treatment process in which a workpiece is heated in an active medium containing the element to be permeated, so that the element simultaneously penetrates into the surface of the workpiece. Through this process, the organizational structure and properties of the material surface can be changed, and the hardness, wear resistance and corrosion resistance of the material can be improved. The co-permeation furnace is an important device to realize this process, which can provide a stable high-temperature environment and active medium to ensure the effective progress of the co-permeation process.

[0003] In the related art, reference can be made to the invention patent with the authorized announcement number of CN106399924B, which discloses a multi-element alloy co-permeation furnace with sufficient mixing and contact, including a rotary heating tank, a heating tank rotary vehicle, a left heating furnace and a right heating furnace. The left heating furnace and the right heating furnace are combined towards each other to form a cylindrical heating cavity. The rotary heating tank is coaxially arranged with the cylindrical heating cavity, and the rotary heating tank is arranged on the heating tank rotary vehicle; four groups of fixed clamping protrusions for clamping the four corners of the metal plate are arranged on the inner wall of the rotary heating tank. On the one hand, it reduces the friction and impact between the metal plate and the rotary heating tank, and on the other hand, it makes the metal plate and the rotary heating tank rotate synchronously, so that the contact and mixing of the metal plate and the co-permeation agent are sufficient.

[0004] During the hoisting, handling and maintenance of the co-permeation furnace, usually ropes are manually fastened to the lifting rings of the furnace body, and after the hoisting machine hoists the furnace body, it is moved and positioned. However, due to the large tonnage of the co-permeation furnace, the furnace body and the ropes are prone to fall off during the hoisting and handling process, and there are potential safety hazards in hoisting.

[0032] The following further elaborates on this application in conjunction with the attached drawings.

[0033] An embodiment of this application discloses a lifting device for a co-permeation furnace. Refer to Figure 1 and Figure 2 , including a lifting frame 1. The lifting frame 1 is arranged in a frame shape. A rope 11 is arranged on the lifting frame 1. There are four ropes 11. One ends of the four ropes 11 are connected to the upper side surface of the lifting frame 1 at four corners. The ends of the four ropes 11 away from the lifting frame 1 are provided with a lifting ring 12. During lifting, the hoisting machine drives the lifting ring 12 and then drives the lifting frame 1 to move.

[0034] Refer to Figure 1 and Figure 2 , a lifting assembly is arranged on the lower side of the lifting frame 1. The lifting assembly includes a lifting plate 2 and a hook 3. The lifting plate 2 is arranged vertically and slidably mounted on the lifting frame 1. A driving member 4 is arranged on the lifting frame 1. There are two hooks 3 and they are located at both ends on the lower side of the lifting plate 2. One end of the hook 3 is rotatably connected to the lifting plate 2. There are two relatively arranged lifting plates 2. The hooks 3 on the relatively arranged two sides of the lifting plates 2 are relatively arranged. A locking member 5 is arranged on the hook 3. When the lifting frame 1 moves to the furnace body, the driving member 4 on the lifting frame 1 drives the two side lifting plates 2 to slide towards each other, driving the hooks 3 to be located at the lifting rings on the side wall of the furnace body. Workers hook the hooks 3 on the lifting rings. The locking member 5 locks and closes one side of the hook 3. At this time, the furnace body is lifted and transported. During the lifting and transportation process, the connection between the furnace body and the hook 3 is tight, and it is not easy for the furnace body to fall off.

[0035] Refer to Figure 1 and Figure 2, the driving member 4 includes a driving motor 41 and a lead screw 42. The lead screw 42 is rotatably installed on the hoisting frame 1. The lead screw 42 and the hoisting plate 2 are perpendicularly distributed. The driving motor 41 is arranged on one side of the hoisting frame 1. The lead screw 42 is connected to the output shaft of the driving motor 41. Two opposite threads are provided on the lead screw 42. One ends of the hoisting plates 2 on the opposite sides are respectively threadedly connected to the lead screw 42 at the two threaded portions. The driving motor 41 drives the lead screw 42 to rotate, and the lead screw 42 drives the hoisting plates 2 on both sides to move towards or away from each other, adjusting the position of the hook 3, which is suitable for hoisting furnace bodies of different sizes. A guide rod 13 is provided on the hoisting frame 1. The guide rod 13 is arranged parallel to the lead screw 42. The hoisting plate 2 is slidably connected to the guide rod 13, and the guide rod 13 guides the sliding of the hoisting plate 2.

A handle 511 is provided on the pressure rod 51. A pressure block 512 is provided at one end of the pressure rod 51. The locking bolt 52 is threadedly installed at the pressure block 512 of the pressure rod 51. A threaded hole 31 is provided at one end of the hook ring of the hook 3. Press one end of the pressure rod 51 against one end of the hook ring of the hook 3, and thread one end of the locking bolt 52 into the threaded hole 31 of the hook ring. At this time, the space between the pressure rod 51 and the hook ring of the hook 3 is closed. The suspension ring of the furnace body is buckled inside the hook 3, and the suspension ring is not easily detached from the hook 3.

[0037] Referring to Figure 3 , a first spring 32 is arranged on the hook ring inside the hook ring. One end of the first spring 32 is connected to the downward side of the pressure rod 51. The first spring 32 pulls one end of the pressure rod 51 to abut tightly against one end of the hook 3, facilitating the quick positioning of the locking bolt 52.

The second spring 612 pulls the sliding rod 61 to be tightly abutted, driving the limiting rod 62 to be tightly abutted at the pressing rod 51, and it is not easy for the limiting rod 62 and the pressing rod 51 to be separated from each other.

[0040] The implementation principle of the lifting device of the co-permeation furnace in the embodiment of the present application is as follows: during lifting, the crane drives the lifting frame 1 to move to the furnace body. The driving motor 41 on the lifting frame 1 drives the lead screw 42 to rotate, driving the two sides of the lifting plates 2 to slide towards each other, driving the hook 3 to be located at the lifting ring of the furnace body. Manually hook the hook 3 at the lifting ring, pull out the limiting rod 62 from the pressing rod 51, the first spring 32 pulls the pressing rod 51 to be tightly pressed at the hook 3, and rotate the locking bolt 52 to lock the pressing rod 51. The hook 3 and the pressing rod 51 are hermetically locked. At this time, the furnace body is lifted and transported. During the lifting and transportation process, the connection between the furnace body and the hook 3 is tight, and it is not easy for the furnace body to fall off.
