Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of steel smelting, and particularly relates to a transport vehicle heat preservation cover for red billet heat preservation. BACKGROUND

[0002] In the steel production process, the transfer of red billets is a key link, but the transfer of red billets often faces the problem of heat loss caused by changes in weather conditions. Due to the heat loss of the billets, more fuel is usually consumed in the heating furnace to increase the temperature of the billets to ensure the smooth progress of the subsequent process.

[0003] Specifically, the influence of the external climate environment (such as low temperature, rain, snow or freezing) on the surface temperature of the billets is particularly significant during the transportation of the billets, especially outdoor open-air transportation. Moisture, rain and snow can accelerate the loss of heat on the surface of the billets, and low-temperature weather can accelerate the cooling speed of the billets, resulting in rapid temperature drop of the billets. The temperature drop of the billets not only directly affects the subsequent processing process, but also increases the burden of the heating furnace, resulting in waste of energy and increase of fuel consumption.

[0004] At present, in order to solve this problem, many steel production enterprises have taken high-temperature compensation measures of the heating furnace, that is, before the billets reach the heating furnace, the billets are preheated to a certain extent by heating equipment. However, this method usually cannot effectively prevent the influence of the external environment on the temperature of the billets, and often needs a large amount of energy input to make up for the loss of heat loss, thereby further increasing the fuel consumption. SUMMARY

[0005] The utility model aims at providing a transport vehicle heat preservation cover for red billet heat preservation to solve the problems in the prior art.

[0007] a bottom plate;

[0008] two end covers, the two end covers are respectively arranged at two ends of the bottom plate;

[0009] a plurality of turnover covers, the plurality of turnover covers are respectively hinged to two sides of the bottom plate;

[0010] a driving device, the driving device is used for driving the turnover cover to rotate relative to the bottom plate.

[0011] Further, the turnover cover comprises a side plate and a top plate, the side plate and the top plate are integrally formed, and the side plate is hinged to the bottom plate. Through the design, the turnover cover can realize the protection of the side and the top after being turned over, so that the turnover cover can complete the forming of the heat preservation cover by performing a single action, and the structure is simple and the heat preservation cover forming process is efficient.

[0012] Further, the number of hinges between the single said flip cover and the bottom plate is two. At least two hinges can ensure the stability of the structure operation, while the number of hinges cannot be too much to avoid the concentricity change of multiple hinges due to the deformation of the steel structure after long-term use, and the rotation of the hinge appears the phenomenon of jamming.

[0013] Further, the said driving device includes a hydraulic oil tank, a hydraulic cylinder and an oil pipeline, the hydraulic cylinder and the hydraulic oil tank are communicated through the oil pipeline, the output end of the hydraulic cylinder is hinged with the flip cover, and the cylinder body of the hydraulic cylinder is hinged with the bottom plate. Through the combination of the hydraulic oil tank, the hydraulic cylinder and the oil pipeline, a hydraulic driving system is formed. The hydraulic cylinder can adapt to the flip path of the flip cover by changing the extension length of the output rod, realize the automatic rotation of the flip cover, and has high strength support stability.

[0014] Further, the side wall of the bottom plate is provided with a wing plate, the cylinder body of the hydraulic cylinder is hinged with the wing plate, the hydraulic oil tank is arranged on the end cover, and the oil pipeline penetrates through the wing plate. The wing plate is fixed with the bottom plate as an extension structure of the bottom plate, and the cylinder body of the hydraulic cylinder is hinged with the wing plate, which can optimize the output angle of the hydraulic cylinder and avoid the dead point position between the hydraulic cylinder and the flip cover, so that the flip cover cannot be flipped or the flip cover is laborious. The hydraulic oil tank is arranged on the relatively static end cover, which has a stable working environment. The oil pipeline can work inside the wing plate, avoiding the influence of external harsh environment or high temperature on the oil pipeline.

[0015] Further, the inner lining of the flip cover is filled with thermal insulation cotton. Thermal insulation cotton can significantly enhance the heat insulation performance of the heat preservation cover, effectively prevent the heat loss of red steel billet in extreme weather and during vehicle transportation.

[0016] Further, the said end cover is formed by welding a plurality of steel plates, and the plurality of steel plates are fixed by rivets. The steel plates are welded to form a whole sealing structure, which protects the internal thermal insulation cotton from being eroded by the external environment. Rivets are used between the steel plates to prevent the welding seam from cracking due to the deformation of the steel plates caused by heat, which may cause the thermal insulation cotton to fall off and affect the thermal insulation effect.

[0017] Further, the inner lining of the end cover is filled with thermal insulation cotton. In addition to enhancing the overall thermal insulation effect of the heat preservation cover, filling the end cover with thermal insulation cotton can also improve the working environment of the hydraulic oil tank, reduce the working temperature of the hydraulic oil tank, and ensure the stability of the hydraulic system operation.

[0018] Further, the said end cover is formed by welding a plurality of steel plates, and the plurality of steel plates are fixed by rivets. Similarly, the steel plates are welded to form a whole sealing structure, which protects the internal thermal insulation cotton from being eroded by the external environment.

It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0026] It is apparent that the accompanying drawings described below are only some examples or embodiments of the present application, and for those skilled in the art, the present application can also be applied to other similar situations according to the drawings without creative labor. In addition, it can be understood that although the efforts made in this development process can be complex and lengthy, some design, manufacture or production changes based on the technology disclosed in the present application are only routine technical means for those skilled in the art related to the disclosure of the present application, and should not be understood as insufficient disclosure of the present application.

[0027] However, unnecessary detailed description can be omitted. For example, there are cases where detailed description of well-known matters, repeated description of actually identical structures is omitted. This is to avoid the following description unnecessarily becoming lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application, and are not intended to limit the subject matter recited in the claims.

[0028] Please refer to Figs. 1-2 As shown in the drawings, in the utility model embodiment, a kind of transport car heat preservation cover for red billet heat preservation, including bottom plate 1, two end caps 2, several turnover covers 3 and drive device 4. Two end caps 2 are respectively arranged at the two ends of bottom plate 1. Several turnover covers 3 are respectively hinged to the two sides of bottom plate 1. Drive device 4 is used to drive the rotation of turnover cover 3 relative to bottom plate 1.

[0029] Turnover cover 3 is connected with bottom plate 1 by hinged structure, and can rotate relative to bottom plate 1. When the heat preservation cover is closed, drive device 4 controls the rotating action of turnover cover 3, so that turnover cover 3 completes the opening and closing process. Turnover cover 3, bottom plate 1 and end cap 2 form a sealed heat preservation environment together, completely wrapping the red billet, and realizing full-closed protection of the red billet during the transportation of the transport car, effectively preventing heat loss.

[0030] Turnover cover 3 is integrally formed by side plate 31 and top plate 32, and side plate 31 is hinged to bottom plate 1. One turnover cover 3 is arranged on each side of bottom plate 1. When the two turnover covers 3 are turned over relative to each other, the edges of the two top plates 32 are in contact with each other, side plate 31 forms protection for the side of the heat preservation cover, top plate 32 forms protection for the top of the heat preservation cover, and the combination of top plate 32 and side plate 31 can simultaneously realize protection for the side and top of the billet. After turnover cover 3 is rotated to the closed position, top plate 32 and side plate 31 form a complete sealing structure together with end cap 2 and bottom plate 1; when turnover cover 3 is rotated to the open position, the loading space of the transport car can be quickly released, facilitating the loading and unloading of the billet.

[0031] The number of hinges between the single flip cover 3 and the bottom plate 1 is two. The two hinges are evenly distributed at the connection between the flip cover 3 and the bottom plate 1, ensuring smooth rotation of the flip cover 3. After long-term use of the flip cover 3 in a high-temperature environment, the hinges can still maintain good concentricity, avoiding the phenomenon of jamming. The single flip cover 3 is connected to the bottom plate 1 by two hinges, and the number of hinges is moderate, which can ensure the stability of the movement of the flip cover 3 and avoid the problem of jamming caused by too many hinges.

[0032] The driving device 4 is composed of a hydraulic oil tank 41, a hydraulic cylinder 42 and an oil delivery pipeline 43. The hydraulic oil tank 41 provides hydraulic oil, the hydraulic cylinder 42 receives the hydraulic oil through the oil delivery pipeline 43, and drives the piston of the hydraulic cylinder 42 to move. The output rod of the piston of the hydraulic cylinder 42 is telescopic, which drives the flip cover 3 to rotate around the hinge, realizing the opening and closing action. This structure improves the automation degree of the opening and closing operation of the flip cover 3, and the operation is convenient and efficient. The hydraulic system has high support capacity and stable and reliable operation.

[0033] Further, the side wall of the bottom plate 1 is provided with a wing plate 11, which is an extension structure of the bottom plate 1 and is hinged with the cylinder body of the hydraulic cylinder 42, optimizing the installation angle of the hydraulic cylinder 42. In order to avoid the dead point position in the horizontal direction, when the flip cover 3 is in the open state, the hydraulic cylinder 42 forms an angle of 13°-20° with the horizontal plane, reducing the operating burden of the driving device 4. When the angle between the hydraulic cylinder 42 and the horizontal plane is 15°, 12MPa is needed for lifting, and when the hydraulic cylinder 42 is installed horizontally with the horizontal plane, 20MPa is needed for lifting. Therefore, the angle limiting of the hydraulic cylinder 42 can prolong the service life of the hydraulic oil tank 41, without affecting the driver's view and the use of the red billet clamp, while reducing the impact on the vehicle body. The hydraulic oil tank 41 is installed on the end cover 2, and the hydraulic oil tank 41 works stably on the end cover 2. The oil delivery pipeline 43 penetrates the wing plate 11 to realize hidden protection, avoiding damage to the oil delivery pipeline 43 by the external environment.

[0034] A rotating hook is arranged on the end cover 2, and a limiting rod is arranged on the flip cover 3. When the flip cover 3 rotates to the closed position, the rotating hook can be rotated by a certain angle and locked with the limiting rod. The rotating hook prevents the flip cover 3 from tilting due to hydraulic failure through mechanical locking, enhances the structural stability of the heat preservation cover in the closed state, and improves the safety and reliability of the transportation process.

[0035] The inner lining of the flip cover 3 is filled with thermal insulation cotton, which reduces the heat exchange between the steel billet and the external environment by blocking the transfer of heat, and reduces heat conduction and loss by using the heat insulation performance of the thermal insulation cotton. The flip cover 3 is formed by welding several steel plates to form a whole sealed structure, which protects the thermal insulation cotton in the inner lining from the external environment. The several steel plates are fixed by rivets to prevent the weld from deforming or cracking due to high temperature, and to ensure the structural integrity.

[0036] The inner lining of the end cover 2 is filled with thermal cotton, which blocks heat transfer and reduces heat loss from the end of the billet. When the hydraulic oil tank 41 is arranged on the end cover 2, the thermal cotton improves the working environment of the hydraulic oil tank 41, reduces the temperature fluctuation of the red billet on the end cover 2, and ensures the stable operation of the hydraulic system.

[0037] Note that the present application is not limited to the above-described embodiments. The above-described embodiments are merely examples, and embodiments having substantially the same configuration as the technical idea and achieving the same effects as the embodiments within the scope of the technical solution of the present application are included in the technical scope of the present application. Furthermore, within the scope of the gist of the present application, various modifications that can be thought of by those skilled in the art, other modes constructed by combining part of the configuration elements of the embodiments are also included in the scope of the present application.
