Description

Technical Field

[0001] This utility model relates to the field of steel chip pressing and lifting technology, specifically a device for neatly stacking steel chip pressings. Background Technology

[0002] In order to reduce test errors, when conducting melting tests on steel scrap briquettes, it is usually required that the steel scrap briquettes be neatly stacked in a relatively small melting furnace.

[0003] Traditional claw hoisting requires a large operating space and has high requirements for the shape of the object being hoisted, making it unsuitable for smelting furnaces with limited space.

[0004] When traditional electromagnetic hoisting is faced with multiple stacked steel scraps, the transmission of electromagnetic force decreases, making it difficult to maintain the stability of the electromagnetic hoisting.

[0005] Existing technologies, such as CN202410786411.1, describe a quick-fixing device for a centrifugal mixing container. However, its design purpose is to position and quickly fix the mixing container, and the diameter of the iris mechanism in the open state is relatively large, which is difficult to meet the requirements of a small-diameter melting furnace. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the shortcomings of the prior art, this utility model provides a device for neatly stacking steel scrap cakes, which solves the technical problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a device for neatly stacking steel scrap cakes, comprising a lifting cylinder, the interior of which is used to place stacked steel scrap cakes, an opening at the bottom of the lifting cylinder, and an iris opening and closing mechanism connected to the lower end of the lifting cylinder. When the iris opening and closing mechanism is opened, the steel scrap cakes can pass through the bottom of the lifting cylinder; when the iris opening and closing mechanism is closed, the steel scrap cakes cannot pass through the bottom of the lifting cylinder.

[0010] Preferably, the iris opening and closing mechanism includes a bottom ring, on which a sliding ring groove is formed, and a sliding ring is slidably disposed in the sliding ring groove. Multiple blades are rotatably connected to the sliding ring, and each blade has a sliding groove. A fixed post is slidably connected in the sliding groove, and the fixed post is connected between the sliding ring groove and the inner wall of the bottom ring. When the sliding ring rotates clockwise, it can drive the blades to rotate. Due to the restriction of the sliding groove and the fixed post, the end of the blade will also rotate towards the center of the bottom ring. At this time, the iris opening and closing mechanism is in the closed state.

[0011] When the sliding ring rotates counterclockwise, it can drive the blade to rotate. Due to the restriction of the sliding groove and the fixed column, the end of the blade will also rotate towards the outer edge of the bottom ring. At this time, the iris opening and closing mechanism is in the open state.

[0012] Preferably, the shape of the blades is uniform or non-uniform.

[0013] Preferably, the shape of the blade includes an arc segment AB, an upper arc segment AC, and a lower arc segment BC. The radius of the arc segment AB is a, the distance from the center of the arc segment AB to the blade tip C is b, and the sliding ring is rotatably connected to the blade via a rotating shaft with a diameter d1.

[0014] Preferably, it includes a support platform for supporting stacked steel chip patties, wherein the top diameter d4 of the support platform is less than d1-b.

[0015] Preferably, the furnace includes a smelting furnace, and the support platform is disposed at the bottom of the inner wall of the smelting furnace.

[0016] Preferably, it includes an iris control mechanism, an opening rope, a closing rope, and an operating lever. One end of the operating lever is connected to a sliding ring, and the other end extends outside the iris opening and closing mechanism. The iris control mechanism includes a closing pulley, an opening pulley, a closing sleeve, an opening sleeve, a closing pull ring, and an opening pull ring. The closing pulley and the opening pulley are rotatably connected to the outer wall of the lifting cylinder or the bottom ring, and the closing sleeve and the opening sleeve are connected to the outer wall of the lifting cylinder.

[0017] One end of the opening rope is connected to the operating rod, and the other end passes around the opening pulley, through the opening sleeve, and is connected to the opening pull ring. When the opening pull ring is pulled, the opening rope can drive the sliding ring to rotate clockwise through the operating rod.

[0018] One end of the closing rope is connected to the operating lever, and the other end passes around the closing pulley, through the closing sleeve, and then connects to the closing pull ring. When the closing pull ring is pulled, the opening rope can drive the sliding ring to rotate counterclockwise through the operating lever.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] Example 1

[0052] A device for neatly stacking steel scrap cakes includes a lifting cylinder 3. The interior of the lifting cylinder 3 is used to place stacked steel scrap cakes 2. The bottom of the lifting cylinder 3 is provided with an opening. The lower end of the lifting cylinder 3 is connected to an iris opening and closing mechanism 1. When the iris opening and closing mechanism 1 is opened, the steel scrap cakes 2 can enter and exit through the bottom of the lifting cylinder 3. When the iris opening and closing mechanism 1 is closed, the steel scrap cakes 2 cannot enter or exit the bottom of the lifting cylinder 3.

[0053] in:

[0054] The top of the lifting cylinder 3 is usually equipped with a lifting ring 31 for lifting. In order to facilitate observation of whether there is a steel chip patty 2 inside the lifting cylinder 3 and the quantity of the steel chip patty 2, an observation port 32 can be opened on the lifting cylinder 3.

[0055] The iris opening and closing mechanism 1 includes a bottom ring 11. The bottom ring 11 can be connected to the bottom of the lifting cylinder 3 by means of a connecting post 112. A sliding ring groove 111 is provided on the bottom ring 11. A sliding ring 12 is slidably arranged in the sliding ring groove 111. Multiple blades 13 are rotatably connected to the sliding ring 12. A sliding groove 131 is provided on the blades 13. A fixed post is slidably connected in the sliding groove 131. The fixed post is connected between the sliding ring groove 111 and the inner wall of the bottom ring 11. When the sliding ring 12 rotates clockwise, it can drive the blades 13 to rotate. Due to the restriction of the sliding groove 131 and the fixed post, the end of the blade 13 will also rotate towards the center of the bottom ring 11. At this time, the iris opening and closing mechanism 1 is in the closed state.

[0056] When the sliding ring 12 rotates counterclockwise, it can drive the blade 13 to rotate. Due to the restriction of the sliding groove 131 and the fixed column, the end of the blade 13 will also rotate towards the outer edge of the bottom ring 11. At this time, the iris opening and closing mechanism 1 is in the open state.

[0057] The shape of the blades 13 may be uniform or inconsistent. This utility model does not limit the requirement that the shape of the blades 13 must be uniform, but the dimensions should meet the following requirements, including but not limited to:

[0058] 1. The blade 13 can allow the lifting cylinder 3 to enter the smelting furnace 5 at any rotation angle;

[0059] 2. When blade 13 is in the closed position, it can prevent the steel chip cake 2 from falling out of the lifting cylinder 3.

[0060] When used with the support platform 4, the blade 13 has a shape including an arc segment AB, an upper arc segment AC, and a lower arc segment BC. The radius of the arc segment AB is a, and the distance from the center of the arc segment AB to the blade tip C is b. The sliding ring 12 is rotatably connected to the blade 13 via a rotating shaft with a diameter of d1. The support platform 4 is used to support the stacked steel scrap cakes 2. To prevent the top of the support platform 4 from affecting the closed position of the blade 13, the top diameter d4 of the support platform 4 is less than d1-b. The support platform 4 can elevate the stacked steel scrap cakes 2 and leave space for the blade 13 to support them near the bottom edge of the steel scrap cakes 2, which can reduce impact during lifting and placement. The support platform 4 is usually placed at the bottom of the inner wall of the smelting furnace 5 and in the stacking operation area of ​​the steel scrap cakes 2. Note that when placed at the bottom of the inner wall of the smelting furnace 5, a stable material should be selected, and the shape should not affect the smelting process.

[0061] To facilitate control of the iris opening and closing mechanism 1, it includes an iris control mechanism 6, an opening rope, a closing rope, and an operating lever 121. One end of the operating lever 121 is connected to the sliding ring 12, and the other end extends to the outside of the iris opening and closing mechanism 1. The iris control mechanism 6 includes a closing pulley 61, an opening pulley 64, a closing sleeve 62, an opening sleeve 65, a closing pull ring 63, and an opening pull ring 66. The closing pulley 61 and the opening pulley 64 are rotatably connected to the outer wall of the lifting cylinder 3 or the bottom ring 11, and the closing sleeve 62 and the opening sleeve 65 are connected to the outer wall of the lifting cylinder 3.

[0062] One end of the opening rope is connected to the operating lever 121, and the other end passes around the opening pulley 64, passes through the opening sleeve 65, and is connected to the opening pull ring 66. When the opening pull ring 66 is pulled, the opening rope can drive the sliding ring 12 to rotate clockwise through the operating lever 121.

[0063] One end of the closing rope is connected to the operating lever 121, and the other end passes through the closing pulley 61, through the closing sleeve 62, and then connects to the closing pull ring 63. When the closing pull ring 63 is pulled, the opening rope can drive the sliding ring 12 to rotate counterclockwise through the operating lever 121.

[0064] The closing ring 63 and opening ring 66 can be controlled by the auxiliary hook or manually.

[0065] How to use this embodiment:

[0066] S1: Lift the lifting cylinder 3;

[0067] S2: Activate the iris opening and closing mechanism 1 at the bottom of the lifting cylinder 3;

[0068] S3: Place the stacked steel scrap patties 2 onto the support platform 4;
