Description

Technical Field

[0001] This invention relates to the field of billet insulation technology in the steel rolling industry, and particularly to a combined insulation device for a well-stacking cargo location and a top self-resetting side-opening insulation cover. Background Technology

[0002] Currently, in the long product rolling industry with integrated processes, due to limitations in raw material warehouse conditions, billet raw materials are typically stored by using overhead cranes to mechanically clamp billets and stack them in a crisscross pattern on-site without any insulation. Because of this lack of insulation, the hot billets cool down very quickly, requiring secondary heating during rolling, thus hindering the effective utilization of hot billet resources and resulting in energy waste. Summary of the Invention

[0003] The purpose of this invention is to provide a combined insulation device with a top self-resetting side-opening insulation cover for stacked cargo and a top self-resetting side-opening insulation cover to solve the problems of the current steel rolling industry, such as the inability to keep billets warm on site, high energy consumption, and high ambient temperature.

[0004] The solution of this invention is as follows:

[0005] A combined insulation device for a well stack storage location and a self-resetting, side-opening insulated cover includes a well stack insulated storage location and a self-resetting, side-opening hot-rolled steel insulated cover placed on the well stack insulated storage location. The well stack insulated storage location includes a load-bearing frame base, insulation side plates, and guide rib columns. A trigger platform is welded to the top of the insulation frame. The insulation side plates and guide rib columns are symmetrically arranged to position multiple rows of billets. The self-resetting, side-opening hot-rolled steel insulated cover includes an insulation cover frame, a counterweight rolling groove, a counterweight support seat, and a scissor-type telescopic mechanism for lateral extension and retraction. The insulation frame is equipped with a vertical counterweight beam guide column. The counterweight support seat and the counterweight beam are connected as a whole and can slide up and down within the counterweight beam guide column. The counterweight support base has a counterweight rolling groove connected as a whole below it, and a trigger plate is provided in the counterweight rolling groove. Above the counterweight support base is a dynamic tensioning device assembly consisting of a spring tensioning box, a dynamic tensioning wheel, a spring support rod, a spring, and a wire rope fixing rod, assembled on the counterweight support base. The insulation cover frame is equipped with a static tensioning device assembly consisting of a fixed balance support, a static tensioning wheel, and a static tensioning shaft. The innermost two scissor arms of the scissor telescopic mechanism are the active support arm and the balance support arm. The active support arm end cooperates with the counterweight rolling groove to form a transverse sliding structure, providing the main power for the scissor telescopic mechanism to open outwards or retract inwards when the counterweight support base moves upwards or downwards. One end of the tension wire rope is fixedly wound around the balance support arm end. The static tensioning device on the insulation cover frame is connected to the dynamic tensioning device assembly of the counterweight support. One end of the dynamic tensioning device assembly is fixed to a steel wire rope fixing rod on the counterweight support, forming a pulley mechanism. When the counterweight support moves upward, it pulls the tension steel wire rope and compresses the spring within the dynamic tensioning device assembly, causing the balance arm to rotate around the active support shaft on the insulation cover frame. This provides the balancing force for the scissor telescopic mechanism to open outward and the downward deflection force for the anti-scissor telescopic mechanism to open outward. When the counterweight support moves downward, the spring within the dynamic tensioning device assembly extends, keeping the tension steel wire rope and the balance arm constantly taut. This provides the balancing force for the scissor telescopic mechanism to retract and ensures the tension is maintained after the retraction action is completed. The steel wire rope is kept tight and taut. A set of scissor-type telescopic mechanisms is installed on the left and right sides of the insulation cover frame. Each set of scissor-type telescopic mechanisms is connected to the insulation cloth support structure and the heat-resistant insulation cloth. When the scissor-type telescopic mechanism extends to its maximum position, the heat-resistant insulation cloth is opened and covers the top of the stacked insulation storage area. Each set of scissor-type telescopic mechanisms is connected by a counterweight beam to form a synchronous movement structure. The counterweight rolling groove is equipped with a trigger plate. When the self-resetting side-opening hot steel insulation cover is placed on top of the stacked insulation storage area, the trigger plate is supported on the trigger platform. The insulation cover frame assembly descends under its own weight, while the counterweight support seat and counterweight beam assembly rise. The scissor-type telescopic mechanism extends synchronously until the entire insulation cover frame assembly is supported on the trigger platform.

[0006] More specific technical solutions also include: the insulation cover frame is equipped with downward-extending frame support columns, so that when the self-resetting side-opening hot steel insulation cover is stored normally, the frame support columns support it on the storage surface, keeping the scissor telescopic mechanism in a tightened state, storing it with the smallest possible area, not occupying too much space, and ensuring that the lower support arms of the scissor telescopic mechanism do not touch the storage surface.

[0007] Furthermore: In the scissor telescopic mechanism, the balance support arm at the upper scissor arm end and the adjacent first hinge plate are welded to form a first V-shaped scissor arm, and the active support arm at the lower scissor arm end, together with the first hinge plate and the roller shaft, forms a second V-shaped scissor arm. The central rotation hinge points of the first V-shaped scissor arm and the second V-shaped scissor arm are on the active support shaft of the heat insulation cover frame. The extended hinge points then interact with the first hinge plate, the second hinge plate, and the third hinge plate respectively, and are connected to each other by hinge plate shafts to form a scissor telescopic mechanism.

[0008] Furthermore, when the site permits, a self-resetting side-opening hot steel insulation cover turnover storage support frame is installed on one side of the stacked insulated storage location to reduce the hoisting distance during use and storage and improve the hoisting speed during use and storage.

[0009] Furthermore: the counterweight support is equipped with a dynamic tensioning device assembly consisting of a spring tensioning box, a movable tensioning wheel, a spring support rod, a spring, and a wire rope fixing rod. The extension and retraction of the spring is to compensate for the positional difference between the top position of the counterweight support and the top position of the balance arm when the scissor telescopic mechanism extends or retracts, which causes the wire rope to always require pre-tensioning. The thermal insulation cover frame is equipped with a static tensioning device assembly consisting of a fixed balance support, a static tensioning wheel, and a static tensioning shaft. The balance arm of the scissor telescopic mechanism has a balance arm wire rope locking shaft, which is connected by a tensioning wire rope to form a pulley tensioning mechanism. This mechanism provides a balancing force when the scissor telescopic mechanism extends outwards and resists the downward deflection force when the scissor telescopic mechanism extends outwards. It also provides a balancing force during the retraction process of the scissor telescopic mechanism and ensures that the tensioning wire rope does not become loose after the retraction action is completed.

[0010] The advantages of this invention are that it is made of steel and sheet metal, requiring no civil engineering, resulting in low cost; the billet is stacked in a well, facilitating hoisting. The well-stacked rack with an insulated cover achieves fully enclosed insulation, reducing heat loss and environmental heat radiation, thus enabling clean production; the insulated cover requires no power, has a self-resetting mechanism, and is simple, safe, and reliable to operate; and it uses aluminum silicate fiber as the insulation material, which is heat-resistant and has excellent insulation performance.

[0024] like Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, in this invention, the stacked insulated storage location includes a load-bearing frame base A, an insulated side plate B, and a guide rib plate column C. A trigger platform D is welded to the top of the insulated frame. The insulated side plate B and the guide rib plate column C are symmetrically arranged to position multiple rows of billets. The self-resetting side-opening hot steel insulated cover includes an insulated cover frame 1, a counterweight rolling groove 2, a counterweight support seat 9, and a scissor-type telescopic mechanism that extends and retracts to the side. The insulated frame 1 is equipped with a vertical counterweight beam guide column 30. The counterweight support seat 9 is connected to the counterweight beam 16 to form an up-and-down sliding structure. The counterweight rolling groove 2 is located below the counterweight support seat 9 and is connected by a roller 11, a roller shaft 12, and a copper... Set 13 is assembled and connected to the counterweight support 9 as a whole. The spring tensioning box 29 is located on the counterweight support 9 and is equipped with a moving tensioning wheel 22, a spring support rod 18, a spring 15, and a wire rope fixing rod 19 to form a moving tensioning device assembly, which is assembled and connected to the counterweight support 9 as a whole. The heat insulation cover frame 1 is equipped with a fixed balance support 10, a static tensioning wheel 20, and a static tensioning shaft, which is assembled and connected to the heat insulation cover frame 1 as a whole. The two innermost scissor arms of the scissor telescopic mechanism have their middle parts rotating around the active support shaft 6 on the heat insulation cover frame 1, and are assembled and connected to the heat insulation cover frame 1 as a whole through the active support shaft 6. Among them, the active support arm 31 and the counterweight rolling groove are connected to the counterweight rolling groove as a whole. 2. The structure is designed for lateral sliding. One end of the tension wire rope 27 of the balance arm 7 is fixed. The tension wire rope 27 is deflected through the fixed balance support 10 and then connected and fixed to the dynamic tensioning device assembly of the counterweight support 9. When the counterweight support 9 moves upward, it pulls the tension wire rope 27 to compress the spring 15 and drives the active support arm 31 to swing, opening the scissor telescopic mechanism outward. When the counterweight support 9 moves downward, the spring 15 returns to its original position and tensions the tension wire rope 27. This compensates for the pre-tensioning stroke of the dynamic pulley caused by the difference in shape and position between the top position of the counterweight support 9 and the top position of the balance arm 7 when the scissor telescopic mechanism retracts. The scissor telescopic mechanism is located on the left and right sides of the insulation cover frame 1. Each set is configured with a scissor-type telescopic mechanism connected to an insulation cloth support structure 17 and an insulation and heat-resistant cloth 14. When the scissor-type telescopic mechanism extends to its maximum position, the insulation and heat-resistant cloth 14 is fully opened and covers the top of the stacked insulation storage location. Each set of scissor-type telescopic mechanisms is connected by a counterweight beam 16 to form a synchronous movement structure. The counterweight rolling groove 2 is equipped with a trigger plate 26. When the self-resetting side-opening hot steel insulation cover is placed on the top of the stacked insulation storage location, the trigger plate 26 is supported on the trigger platform D. The insulation cover frame 1 assembly descends under its own weight, while the counterweight support seat 9 and the counterweight beam 16 assembly rise. The scissor-type telescopic mechanism extends synchronously until the insulation cover frame 1 assembly is fully supported on the trigger platform D.

[0025] In the scissor telescopic mechanism, the balance support arm 7 at the upper scissor arm end and the adjacent first hinge plate 4 are welded to form a first V-shaped scissor arm. The active support arm 31 at the lower scissor arm end, together with the first hinge plate 3 and the roller shaft 12, forms a second V-shaped scissor arm. The central rotation hinge points of the first V-shaped scissor arm and the second V-shaped scissor arm are on the active support shaft 6 on the heat insulation cover frame 1. The extended hinge points then interact with the first hinge plate 3, the second hinge plate 4, and the third hinge plate 5 respectively, and are connected to each other by hinge plate shaft 8 to form a scissor telescopic mechanism.

[0026] The heat insulation cover frame 1 is provided with a downwardly extending frame support column 28, so that when the self-resetting side-opening hot steel heat insulation cover is stored normally, the frame support column 28 is supported on the storage plane, keeping the scissor telescopic mechanism in a tightened state.

[0027] A self-resetting, side-opening hot steel insulation cover turnover storage support frame H is installed on one side of the well stack insulated cargo space.

[0028] like Figure 11 , 12 This section further elaborates on the working principle and function of the self-resetting side-opening hot steel insulation cover, which includes the insulation cover frame 1 and the upper dynamic tensioning device assembly, based on the actual manufacturing situation where the hinge arm center is 475 mm. Figure 11Without the spring tensioning device, the distance from the center of the movable tensioning wheel 22 assembled on the counterweight rolling groove 2 to the surface of the counterweight rolling groove 2 is 460 mm, and the center of the wire rope fixing rod 19 and the movable tensioning wheel 22 remain unchanged. The position of the static tensioning wheel 20 fixed on the insulation cover frame 1 is also constant. When the tensioning device rises to the highest position and the balance arm 7 rotates to the lower position, the center of the wire rope fixing rod 19 and the center of the movable tensioning wheel 22, the center of the movable tensioning wheel 22 and the center of the static tensioning wheel 20, and the center of the static tensioning wheel 20 and the locking center of the balance arm 7 are 194 mm, 728 mm, and 163 mm, respectively. Therefore, the theoretical total length of the tensioned wire rope 27 is 1085 mm. When the tensioning device descends to its lowest position and the balance arm 7 rotates to its upper position, the center of the wire rope fixing rod 19 is 194 mm from the center of the moving tension wheel 22, the center of the moving tension wheel 22 is 358 mm from the center of the stationary tension wheel 20, and the center of the stationary tension wheel 20 is 517 mm from the locking center of the balance arm 7. Therefore, the theoretical total length of the tensioned wire rope 27 required is 1069 mm. To ensure that the openings of the balance arm 7 and the active arm 31 are aligned, the theoretical actual installation length is 1085 mm. This ensures a balanced force and the downward deflection force of the anti-shear telescopic mechanism when the scissor arm is fully extended. However, it cannot provide a balanced force to tension the wire rope when the scissor telescopic mechanism retracts. Therefore, dynamic adjustment is required during movement by extending and retracting the center of the moving tension wheel 22, which is achieved by adding a spring tensioning device. Through calculation and testing, when the tensioning device descends to the lowest position, the distance from the center of the moving tensioning wheel 22 to the surface of the counterweight rolling groove 2 is 480 mm. When the moving tensioning wheel 22 moves between the high and low positions, and between these positions, the distance is in the range of 460~480 mm. This process is achieved by the extension and contraction of the spring. Figure 12 After spring tensioning is implemented, under a constant theoretical installed length of 1085 mm for the wire rope, it can ensure that when the scissor arm is opened to its maximum, it can balance the force and the downward deflection force when the shear telescopic mechanism opens outward. It can also prevent the wire rope from becoming loose when the shear telescopic mechanism cannot provide a balancing force to tension it when it retracts.

[0029] The present invention will be described in detail below with reference to a specific embodiment:

[0030] like Figure 8 , 9 As shown in Figure 10, this embodiment specifies a stacking of 1554 billets at a time, with a maximum single billet size of 165×165×11500 mm. The billets are arranged in 6 groups per layer of 37 layers, with 7 billets per group, stacked in a crisscross pattern. A 25T clamp is used for lifting, with a jaw opening of 1650 mm and a span of 3000 mm. The stacked insulated storage box is designed based on the space occupied by the billet stacking and the clamp lifting dimensions, and is equipped with a self-resetting insulated cover to form a sealed, insulated space, achieving the design goal of reducing heat loss.

[0031] The hot billet stacking insulated storage area is designed with 37 layers of billets stacked flat, occupying a height of 6105mm. The overall length and width of the insulated rack are 13000mm, and the side panel height is 6200mm, ensuring sufficient storage space for the hot billets. The bottom of the stacking insulated storage area has a welded load-bearing frame base A, with 200mm thick insulating material inside. Sixteen symmetrically arranged guide ribs C are welded around the top of the load-bearing frame base A, and then assembled and welded to the insulated side panels B. The insulated side panels B are designed and manufactured to standard specifications of 3000mm*1800mm, with 100mm thick aluminum silicate fiber insulation material inside. During installation, they are embedded into the guide ribs C and then welded together. The top of the stacking insulated storage area is connected to form a single plane, facilitating construction and installation, while also strengthening the overall structural rigidity and preventing deformation due to accidental impact during hoisting, forming a semi-enclosed box-type insulated structure. An insulated cover turnover support frame H is installed on one side of the stacking insulated storage area for convenient turnover of the insulated covers.

[0032] Self-resetting side-hinged hot steel insulation cover: To achieve fully enclosed insulation of the hot billet rack, self-resetting insulation covers are added after the 37 layers of hot billets are hoisted into the rack. Due to the large top area of ​​the well-stacking insulated storage location, using a single cover would be too bulky, inconvenient to operate, and inconvenient for storage. Using multiple covers would be too numerous, and the operational pace would not meet actual requirements. Therefore, a movable insulation curtain is designed on the hinge mechanism of the insulation cover plate, using only two insulation covers to fully enclose the top of the well-stacking insulated storage location. The insulation cover fits seamlessly with the rack's perimeter and is lifted in and out using clamps. To achieve the functions of large-area coverage, small-area hoisting and storage, and reasonable operational frequency, the movable insulation curtains on both sides adopt a self-resetting design.

[0033] The main frame of the self-resetting side-opening hot-rolled steel insulation cover is welded using 18# groove welding and internally sealed with aluminum silicate fiber insulation material. The frame has a plane dimension of 13130mm × 1670mm. In use, it is fixedly placed on the insulated storage location of the well stack and can support the entire insulation cover.

[0034] When the insulation cover is in the hoisted or flat position, the insulation curtain is retracted through the action of the counterweight mechanism, the pulley mechanism of the dynamic tensioning device and the static tensioning device, and the scissor-type telescopic hinge mechanism, achieving the smallest possible area for hoisting and storage. At the working position, the upper side plate of the insulated storage location contacts the trigger plate of the cover plate's counterweight mechanism. The retraction is achieved through the action of the upper side plate of the counterweight mechanism, the pulley mechanism of the dynamic tensioning device and the static tensioning device, and the scissor-type telescopic hinge mechanism. The roller groove descends, allowing the insulation curtain to unfold with the movable hinge mechanism, automatically closing the shelf.

[0035] like Figure 5As shown, the self-resetting side-opening hot steel insulation cover, when stored normally, is powered by the weight of the counterweight beam 15. This weight causes the counterweight support 9 and the counterweight rolling groove 2 to descend. The counterweight rolling groove 2 compresses the second V-shaped scissor arm, which is composed of the first hinge plate 3, the roller shaft 12, and the active support arm 31. At the same time, the tension wire rope 27 pulls the balance support arm 7 and the first V-shaped scissor arm, which is welded to the adjacent hinge plate 4. Both V-shaped scissor arms rotate around the active support shaft 6 on the insulation cover frame 1 to form a scissor-like opening state. This causes the scissor-like telescopic mechanism, which is connected by the hinge plate shaft 8, the first hinge plate 3, the second hinge plate 4, and the third hinge plate 5, to automatically reset and retract laterally. In this process, the dynamic tensioning device assembly assembled on the counterweight support 9, the static tensioning device assembly installed on the insulation cover frame 1, and the pulley tensioning mechanism formed by connecting the balance arm 7 through the tensioning wire rope 27, function to provide balancing force and pre-tension the wire rope during the retraction process of the scissor telescopic mechanism, preventing it from becoming loose. Note the role of the frame support column 28, which provides support when the insulation cover is stored on a flat surface in the tightened state.

[0036] like Figure 8 , 9 As shown in Figure 10, the well-stabilized storage location consists of a load-bearing frame base A, insulation side plates B, and guide rib columns C. The load-bearing frame base A protects the billets and prevents deformation of the overall frame when hot billets are stacked. The insulation side plates B and guide rib columns C are symmetrically arranged to accommodate seven rows of billets. A trigger platform D is welded to the top of the insulation frame. A self-resetting side-opening hot steel insulation cover E is hoisted onto the billets via clamping station F. When the self-resetting side-opening hot steel insulation cover E descends, it... Figure 2 Trigger board 26 connection Figure 3 The trigger platform D is supported by trigger plate 26. The insulation cover frame 1 assembly descends under its own weight, while the counterweight support 9 and counterweight beam 16 assembly rise. The scissor telescopic mechanism extends synchronously until the entire insulation cover frame 1 assembly is supported by trigger platform D. The action is the opposite of the tightening state. During this process, the dynamic tensioning device assembly assembled on the counterweight support 9, the static tensioning device assembly installed on the insulation cover frame 1, and the pulley tensioning mechanism formed by connecting the balance arm 7 through the tensioning wire rope 27 function to resist the downward deflection force when the scissor telescopic mechanism opens and the balancing force during the action.

[0037] like Figure 8 As shown, a self-resetting side-opening hot steel insulation cover turnover support frame H is installed on the right side of the stacked insulated goods position. The self-resetting side-opening hot steel insulation cover in the tightened state can be placed on the placement point G on the turnover support frame H for storage, ready for use.
