Description

Technical Field

[0001] The utility model relates to the technical field of horizontal tempering furnaces, in particular to an inner liner inlet and outlet support mechanism of a horizontal tempering furnace. Background Art

[0002] In order to reduce the residual stress in the quenched metal, the quenched metal needs to be sent to the tempering furnace for tempering. The tempering furnace includes a horizontal tempering furnace, which includes a furnace body and an inner tank arranged inside the furnace body. A heating device is arranged inside the inner tank, and the inner tank is used to isolate heat. An inlet is arranged at the left end of the furnace body, and hanging rings are arranged at the left and right ends of the top of the outer wall of the inner tank.

[0003] When the inner liner of the horizontal tempering furnace is maintained, the inner liner needs to be taken out of the furnace body, and after the maintenance is completed, the inner liner is returned to the furnace body. When taking out the inner liner, first use a hook of the overhead crane to hook the ring on the left end of the inner liner, and then pull the inner liner outward. As the inner liner is moved out, use the second hook of the overhead crane to hook the ring on the right end of the inner liner, and continue to pull the inner liner outward to take it out. When returning the inner liner, use the two hooks of the overhead crane to hang the rings on the left and right ends of the inner liner. As the inner liner enters, first release the hook connected to the ring on the right end of the inner liner, and continue to send the inner liner in. When the inner liner is completely in the furnace body, contact the hook connected to the ring on the left end of the inner liner.

[0004] During the process of the inner liner entering and exiting the furnace body, the portion of the inner liner outside the furnace body can only be lifted by the overhead crane, which makes the portion of the inner liner outside the furnace body easy to shake and difficult to stabilize, thereby reducing safety.

[0005] Therefore, how to improve the stability of the inner tank when entering and exiting the furnace body is a technical problem that needs to be solved at present. Utility Model Content

[0006] In view of the above-mentioned deficiencies in the prior art, the utility model provides an inner liner inlet and outlet support mechanism for a horizontal tempering furnace. The utility model can improve the stability of the inner liner when it is inlet and outlet of the furnace body.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A liner in and out support mechanism for a horizontal tempering furnace comprises a furnace body and an liner arranged inside the furnace body, an entrance is arranged at the left end of the furnace body, hanging rings are arranged at the left and right ends of the top of the outer wall of the liner, a base plate is arranged at the left end of the bottom of the outer wall of the liner, a slide seat, a driving structure and a first limit block are arranged at the bottom of the base plate, the driving structure is used to drive the slide seat to move left and right, the first limit block is arranged at the left end of the base plate, a support rod is rotatably connected to the lower part of the side wall of the slide seat, a roller is rotatably connected to the bottom of the support rod, a limit rod is arranged on the right side of the top of the support rod, the limit rod is arranged vertically to the support rod, and a second limit block is arranged on the upper part of the side wall of the slide seat, when the driving structure drives the slide seat to move left, the side of the support rod abuts against the first limit block, and when the limit rod abuts against the second limit block, the support rod is in a vertical state.

[0009] Furthermore, a slide rail is provided at the bottom of the base plate, the slide rail extends in the left-right direction, and the slide seat is slidably matched with the slide rail.

[0010] Furthermore, the driving structure includes a telescopic rod, which is arranged at the right end of the base plate, and the output end of the telescopic rod is connected to the slide seat.

[0011] Furthermore, the telescopic rod adopts an oil cylinder, an air cylinder or an electric push rod.

[0012] Furthermore, the support rods are provided on both the front and rear sides of the slide seat.

[0013] Furthermore, two rows of moving wheels are provided on the lower side of the outer wall of the inner container, the base plate is provided between the two rows of moving wheels, and two rows of tracks are provided on the lower side of the inner wall of the furnace body, and one row of moving wheels cooperates with one row of tracks.

[0014] The utility model has the beneficial effects:

[0015] 1. When the driving structure drives the slide to move to the left, the side of the support rod abuts against the first limit block, and the limit rod abuts against the second limit block, the support rod can be kept in a vertical state, and the roller at the bottom of the support rod can contact the ground. Therefore, when the hook of the overhead crane hooks the ring on the inner liner and the overhead crane drives the inner liner in and out of the furnace body, the support rod and the roller can support the part of the inner liner located outside the furnace body, reducing the probability of the inner liner shaking, so that the stability of the inner liner when entering and exiting the furnace body is improved. Therefore, it is beneficial to improve the safety of the inner liner when entering and exiting the furnace body.

[0016] 2. When the inner tank enters the furnace body, the driving structure drives the slide to move to the right, so that the support rod can rotate clockwise and gradually retract into the furnace body, thereby facilitating the storage of structures such as the support rod and rollers.

[0017] 3. By using an oil cylinder, a pneumatic cylinder or an electric push rod as a telescopic rod, it is convenient to obtain materials and is conducive to improving assembly efficiency.

[0018] 4. By arranging moving wheels on the lower side of the outer wall of the inner tank and tracks on the lower side of the inner wall of the furnace body, the moving wheels and tracks can be used to support the part of the inner tank entering the furnace body, which can further improve the stability and safety of the inner tank entering and exiting the furnace body.

[0037] Example:

[0038] like Figure 1-Figure 15 As shown, an inner liner inlet and outlet support mechanism of a horizontal tempering furnace comprises a furnace body 1, and an inlet 101 is arranged at the left end of the furnace body 1.

[0039] An inner container 2 is provided inside the furnace body 1 , and hanging rings 3 are welded and fixed to the left and right ends of the top of the outer wall of the inner container 2 .

[0040] A base plate 4 is provided at the left end of the bottom of the outer wall of the inner container 2. The base plate 4 and the inner container 2 can be fixed by welding or fastened together with bolts.

[0041] A slide rail 5 , a slide seat 6 , a driving structure, and a first limit block 8 are provided at the bottom of the base plate 4 .

[0042] The slide rail 5 is fixed to the base plate 4 by welding, and the slide rail 5 extends in the left-right direction.

[0043] The slide seat 6 is slidably matched with the slide rail 5 .

[0044] The driving structure is used to drive the slide 6 to move left and right. The driving structure includes a telescopic rod 7, which is fixedly mounted on the right end of the base plate 4. The output end 71 of the telescopic rod 7 is fixedly connected to the slide 6. The telescopic rod 7 adopts an oil cylinder, an air cylinder or an electric push rod. When the output end 71 of the telescopic rod 7 is extended, the output end 71 of the telescopic rod 7 pushes the slide 6 to move left; when the output end 71 of the telescopic rod 7 is retracted, the output end 71 of the telescopic rod 7 pulls the slide 6 to move right.

[0045] The first limiting block 8 is welded and fixed to the left end of the base plate 4 .

[0046] The lower part of the front side wall and the lower part of the rear side wall of the slide 6 are both rotatably connected to the support rod 9, and the bottom of the support rod 9 is rotatably connected to the roller 10. A limit rod 11 is provided on the right side of the top of the support rod 9, and the limit rod 11 is vertically arranged with the support rod 9, and the limit rod 11 and the support rod 9 are an integral structure. The upper part of the front side wall and the upper part of the rear side wall of the slide 6 are both provided with a second limit block 12, and the second limit block 12 and the slide 6 are an integral structure.

[0047] In addition, two rows of moving wheels 13 are installed on the lower side of the outer wall of the inner tank 2, and the base plate 4 is arranged between the two rows of moving wheels 13. Two rows of tracks 14 are welded and fixed on the lower side of the inner wall of the furnace body 1, and one row of moving wheels 13 cooperates with one row of tracks 14.

[0048] The working principle of this embodiment is as follows:

[0049] (1) When the inner container 2 needs to be delivered into the furnace body 1 from the inlet 101 of the furnace body 1, the following operations need to be performed:

[0050] ① Use the two hooks of the overhead crane to hook the lifting rings 3 at the left and right ends of the inner liner 2 and lift the inner liner 2.

[0051] ② Start the telescopic rod 7, and the output end 71 of the telescopic rod 7 pushes the slide 6 to the left until the side of the support rod 9 on the slide 6 abuts against the first limit block 8. At this time, the limit rod 11 on the top of the support rod 9 also abuts against the second limit block 12.

[0052] Because the side of the support rod 9 abuts against the first limit block 8, the support rod 9 cannot continue to rotate clockwise; because the limit rod 11 abuts against the second limit block 12, the support rod 9 cannot rotate counterclockwise, so that the support rod 9 can remain in a vertical state.

[0053] ③ Use an overhead crane to lower the height of the inner liner 2 so that the roller 10 at the bottom of the support rod 9 contacts the ground, so that the inner liner 2 is supported by the support rod 9 and the roller 10.

[0054] ④ Maintain the current height of the inner tank 2, and use the overhead crane to send the inner tank 2 to the inside of the furnace body 1. In this process, the support rod 9 and the roller 10 support the inner tank 2.

[0055] As the inner container 2 goes deeper into the furnace body 1, when the hook connected to the lifting ring 3 at the right end of the inner container 2 is blocked by the entrance 101 of the furnace body 1, the hook is released and the inner container 2 continues to be transported into the furnace body 1. In this process, the support rod 9 and the roller 10 support the inner container 2.

[0056] When the inner container 2 is about to completely enter the furnace body 1, the support rod 9 approaches the entrance 101. At this time, the output end 71 of the telescopic rod 7 is activated to pull the slide seat 6 to move to the right. Figures 9 to 14 The state changes, the support rod 9 leaves the first limit block 8, and the support rod 9 is pushed by the edge of the entrance 101 to rotate clockwise, so that the support rod 9 is gradually retracted and enters the interior of the furnace body 1.

[0057] A forklift can be used to help push the inner liner 2 until the inner liner 2 completely enters the interior of the furnace body 1, and then the hook connected to the lifting ring 3 at the left end of the inner liner 2 is released. At this point, the operation of transporting the inner liner 2 into the furnace body 1 can be completed.

[0058] (2) When the inner container 2 needs to be removed from the furnace body 1, the following operations need to be performed:

[0059] ① Use a hook of the overhead crane to hook the lifting ring 3 at the left end of the inner tank 2, and use the overhead crane to pull the inner tank 2 toward the outside of the furnace body 1 until the base plate 4 at the left end of the bottom of the inner tank 2 is exposed.

[0060] ② Start the telescopic rod 7, and the output end 71 of the telescopic rod 7 pushes the slide 6 to the left, see Figure 14 to Figure 9 The state changes until the side of the support rod 9 on the slide 6 abuts against the first limit block 8, and the limit rod 11 on the top of the support rod 9 also abuts against the second limit block 12, so that the support rod 9 is in a vertical state, and the roller 10 at the bottom of the support rod 9 falls on the ground, so that the inner liner 2 is supported by the support rod 9 and the roller 10.

[0061] ③ Use the overhead crane to continue pulling the inner liner 2 to the outside of the furnace body 1. During this process, the support rod 9 and the roller 10 maintain the support function for the inner liner 2. When the lifting ring 3 at the right end of the inner liner 2 is close to the entrance 101, use the second lifting hook of the overhead crane to hook the lifting ring 3, and use the overhead crane to continue pulling the inner liner 2 to the outside of the furnace body 1 until the inner liner 2 is completely removed, and then use the overhead crane to lift the inner liner 2 away.

[0062] It can be known from the above working principle that when the driving structure drives the slide 6 to move to the left, the side of the support rod 9 abuts against the first limit block 8, and the limit rod 11 abuts against the second limit block 12, the support rod 9 can be kept in a vertical state, and the roller 10 at the bottom of the support rod 9 can contact the ground. Therefore, when the hook of the overhead crane hooks the ring 3 on the inner liner 2 and the overhead crane drives the inner liner 2 in and out of the furnace body 1, the support rod 9 and the roller 10 can support the part of the inner liner 2 located outside the furnace body 1, reduce the probability of the inner liner 2 shaking, and improve the stability of the inner liner 2 when entering and exiting the furnace body 1. Therefore, it is beneficial to improve the safety of the inner liner 2 when entering and exiting the furnace body 1.

[0063] When the inner container 2 enters the furnace body 1, the driving structure drives the slide 6 to move rightward, so that the support rod 9 can rotate clockwise and gradually retract into the furnace body 1, thereby facilitating the storage of structures such as the support rod 9 and the roller 10.

[0064] By using an oil cylinder, a gas cylinder or an electric push rod as the telescopic rod 7, it is convenient to obtain materials, which is beneficial to improving the assembly efficiency.

[0065] By arranging moving wheels 13 on the lower side of the outer wall of the inner tank 2 and rails 14 on the lower side of the inner wall of the furnace body 1, the moving wheels 13 and the rails 14 can be used to support the part of the inner tank 2 entering the furnace body 1, which can further improve the stability and safety of the inner tank 2 entering and exiting the furnace body 1.

[0066] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
