Description

Technical Field

[0001] This utility model belongs to the technical field of hot conveying equipment for steel rolling raw materials in the metallurgical industry, and specifically relates to a flip-top device for a hot steel billet insulation car. Background Technology

[0002] Currently, steel mills use both automated roll conveyor systems and road transport to transfer hot steel billets produced in converters to the rolling mill line. Automated roll conveyor systems require a rational workshop layout and production scheduling, which many domestic steel mills cannot yet achieve. Due to space constraints, they rely solely on road transport for internal transfers.

[0003] The current method of road transport involves laying steel rails on open semi-trailers. Freshly baked hot billets, reaching temperatures of 800 to 900 degrees Celsius, are placed directly on the rails for open transport. During transport and cooling at room temperature, the different cooling rates between the outside and inside of the billets easily cause the ends of longer billets to bend and the middle to arch, resulting in deformation, difficulty in unloading, and a high scrap rate in the rolling mill. Furthermore, current hot billet insulated trucks are bulky, typically employing a simple fixed box structure with a movable top cover. Opening and closing these insulated trucks is cumbersome, loading and unloading are time-consuming, and production efficiency is low.

[0004] Therefore, it is imperative to manufacture vehicle insulation devices to implement refrigerated transportation in order to reduce energy consumption during transportation and improve loading and unloading efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a flip-top device for a hot steel billet insulation truck. Through a hydraulic flipping mechanism, the half-section of the truck body is driven to open and close stably, effectively controlling and "locking in" the temperature while also improving loading and unloading efficiency. The specific technical solution is as follows:

[0006] A hot steel billet insulation car flip-top device includes a car floor and insulated half-sections symmetrically and rotatably mounted on both sides of the car floor. A hydraulic flipping mechanism is also provided on the opposite sides of the car floor. The hydraulic flipping mechanism is rotatably connected to the insulated half-sections through hinge supports. The hinge supports are installed on the outer side of the insulated half-sections. The hydraulic flipping mechanism drives the insulated half-sections to flip and open around the side edge of the car floor.

[0007] Preferably, the insulated semi-compartment includes a side cover plate, a rear door panel, a front baffle, a top cover plate, a pressure strip, and a square beam. The front baffle and the rear door panel are respectively connected to the front and rear ends of the side cover plate. The front baffle and the rear door panel are perpendicular to the side cover plate. The top cover plate is installed on the top of the side cover plate. The pressure strip is installed at the outer edge of the top cover plate on any of the insulated semi-compartments. The pressure strip is used to press down on another top cover plate that does not have the pressure strip to achieve a sealing effect. The square beam is installed on the side of the vehicle compartment floor.

[0008] Preferably, the side cover is rotatably mounted on the side of the carriage floor via a flip-mounted mounting seat, and the square beam is located on the outside of the flip-mounted mounting seat.

[0009] Preferably, the top cover plate and the side cover plate form an angle of 93°.

[0010] Preferably, the side cover, rear door panel, front baffle and top cover are made of steel plates with a thickness of 5mm.

[0011] Preferably, the hinge support is mounted on the side cover plate, and the hydraulic tilting mechanism includes a hydraulic telescopic cylinder, a tilting pin seat, and a tilting pin. The hydraulic telescopic cylinder is rotatably mounted on the tilting pin seat via the tilting pin, and the tilting pin seat is mounted on the square beam. The telescopic rod of the hydraulic telescopic cylinder is rotatably connected to the hinge support.

[0012] Preferably, the interior of the insulated semi-compartment is further provided with an insulation structure, which is installed on the inner wall of the insulated semi-compartment. The insulation structure includes a heat insulation cotton fixing bracket and heat insulation cotton. The heat insulation cotton fixing bracket is installed on the inner wall of the insulated semi-compartment, and the heat insulation cotton is filled in the heat insulation cotton fixing bracket.

[0013] Compared with existing technologies, this utility model has the following beneficial effects:

[0014] 1. This utility model provides a hot steel billet insulated car flipping device, which consists of two symmetrical insulated half-boxes. The two insulated half-boxes are driven to close or open by a hydraulic flipping mechanism. Through the automated assembled insulated car, the loading and unloading efficiency before transportation can be further improved.

[0015] 2. The insulated truck cover-flipping device provided by this utility model has an insulation structure on its inner wall. The insulation structure makes the transport compartment a "thermal box", which effectively controls and "locks in" the temperature. At the same time, it can prevent the deformation of hot steel billets caused by the difference between the external and internal cooling rates, reduce the scrap rate of rolled steel, and shorten the secondary heating time of steel billets before rolling.

[0026] Example

[0027] like Figures 1 to 3 As shown, a hot steel billet insulated truck cover flipping device includes a truck floor 100 and insulated half-body 200 symmetrically rotatably mounted on both sides of the truck floor 100. Hydraulic flipping mechanisms 300 are also provided on opposite sides of the truck floor 100. The output end of the hydraulic flipping mechanism 300 is rotatably connected to the insulated half-body 200 via a hinge support 400. The hinge support 400 is installed on the outer side of the insulated half-body 200. The hydraulic flipping mechanism 300 drives the insulated half-body 200 to flip and open around the side edge of the truck floor 100. In use, the hydraulic flipping mechanism 300 drives the left and right halves of the insulated half-body 200 to flip and open. The insulated semi-trailer 200 slowly tilts and opens, providing space for the billet lifting operation. After the hot steel billet is loaded, the hydraulic tilting mechanism 300 is driven again to slowly close the left and right halves of the insulated semi-trailer 200, forming a complete "insulated box". This assembled "insulated box" effectively controls and "locks in" the temperature, extending the service life of the semi-trailer. It also prevents deformation of the hot steel billet due to the difference in cooling rates between the outside and inside, reduces the scrap rate of rolled steel, and shortens the secondary heating time before billet rolling. At the same time, the automated assembly of the insulated semi-trailer 200 improves loading and unloading efficiency, further improving production and transportation efficiency.

[0028] Preferably, the insulated semi-compartment 200 is assembled from side cover plates 210, rear door panels 220, front baffles 230, top cover plates 240, pressure strips 250, and square beams 260. The front baffles 230 and rear door panels 220 are respectively connected to the front and rear ends of the side cover plates 210. The front baffles 230 and rear door panels 220 are perpendicular to the side cover plates 210. The top cover plate 240 is installed on the top of the side cover plates 210. The pressure strips 250 and 260 are... The top cover plate 240 is installed on the outer edge of any of the insulated half-body 200. The pressure strip 250 is used to press down on another top cover plate 240 that is not provided with the pressure strip 250 to achieve a sealing effect. The square beam 260 is installed on the side of the car floor 100. Further, the side cover plate 210 is rotatably installed on the side of the car floor 100 via the flip mounting seat 270. The square beam 260 is located outside the flip mounting seat 270.

[0029] In some preferred embodiments, the top cover plate 240 and the side cover plate 210 form a 93° angle, which is intended to create a certain slope on the top surface, so that rainwater can flow down the slope during the rainy season and will not accumulate on the top, further ensuring heat preservation during transportation to prevent heat loss, and preventing rainwater from seeping in.

[0030] In some preferred embodiments, the side cover plate 210, rear door plate 220, front baffle 230 and top cover plate 240 are steel plates with a thickness of 5mm. In order to stabilize the structure of the insulated semi-compartment 200, multiple square steel bars and channel steel bars are also provided on the side cover plate 210, rear door plate 220, front baffle 230 and top cover plate 240 for reinforcement.

[0031] Preferably, the hinge support 400 is mounted on the side cover plate 210, and the left and right halves of the insulated half-body 200 are opened and closed by a hydraulic tilting mechanism 300, which facilitates the loading and unloading of hot steel billets and insulated transportation. Specifically, the hydraulic tilting mechanism 300 includes a hydraulic telescopic cylinder 310, a tilting pin seat 320, and a tilting pin 330. The hydraulic telescopic cylinder 310 is rotatably mounted on the tilting pin seat 320 through the tilting pin 330. The tilting pin seat 320 is mounted on the square beam 260. The telescopic rod of the hydraulic telescopic cylinder 310 is rotatably connected to the hinge support 400. Multiple hydraulic telescopic cylinders 310 are provided on the outer side of the side cover plate 210.

[0032] Preferably, the interior of the insulated semi-compartment 200 is further provided with an insulation structure 500. The insulation structure 500 is installed on the inner wall of the insulated semi-compartment 200 (specifically, on the inner walls of the side cover plate 210, rear door panel 220, front baffle 230, and top cover plate 240). The insulation structure 500 includes a heat insulation cotton fixing bracket 510 and heat insulation cotton 520. The heat insulation cotton fixing bracket 510 is installed on the inner wall of the insulated semi-compartment 200, and the heat insulation cotton 520 is filled in the heat insulation cotton fixing bracket 510. After the insulation structure 500 is installed, when you reach close to the "insulated box", you will feel a warm temperature, without the scorching heat of 600-700 degrees Celsius of the hot billet. This keeps the temperature difference of the hot billet within 100 to 200 degrees Celsius, reducing the enterprise's production energy consumption costs, achieving cost reduction and efficiency improvement, and enhancing the enterprise's operating efficiency.

[0033] In some preferred embodiments, the heat insulation cotton fixing bracket 510 is composed of multiple flat iron pieces, steel bars, and channel steel. The flat iron pieces and channel steel are welded at different intervals to the inner walls of the side cover plate 210, rear door panel 220, front baffle 230, and top cover plate 240 to form a fixing bracket for installing the heat insulation cotton 520. The heat insulation cotton 520 is then filled into the area enclosed by the heat insulation cotton fixing bracket 510. The heat insulation barrier formed by the heat insulation cotton 520 can effectively "lock" the temperature of the hot steel billet, ensuring that the hot steel billet will not deform due to uneven heating and cooling during transportation, nor will it increase the energy consumed by secondary heating due to excessive heat dissipation.

[0034] In summary, this utility model provides a hot billet insulated car flipping device, which consists of two symmetrical insulated half-boxes. A hydraulic flipping mechanism drives the two insulated half-boxes to close or open. Through automated assembly of the insulated car, the loading and unloading efficiency before transportation can be further improved. The insulated car flipping device provided by this utility model has an insulation structure on its inner wall, which forms an "insulated box" for the transport car, effectively controlling and "locking in" the temperature. It also prevents deformation of the hot billet due to differences in cooling rates between the outside and inside, reduces the scrap rate of rolled steel, and shortens the secondary heating time before billet rolling.
