Description

Technical Field

[0001] The utility model belongs to the technical field of chemical industry and steel metallurgy, and in particular relates to an automatically opened and closed heat preservation cover device. Background Art

[0002] In the transportation process of high-temperature materials, molten steel, etc. in the chemical and steel metallurgical industries, in order to reduce the heat loss of high-temperature materials, an insulation cover is generally added to the top of the material box or tank, and a separate overhead crane is used to hoist the insulation cover on the top of the material box or tank. The hoisting position is very inaccurate, and a separate overhead crane is also required to hoist the insulation cover down when arriving at the destination. This operation method is inefficient and easily damages the insulation material in the insulation cover, which restricts the improvement of the transportation capacity of high-temperature materials.

[0003] Existing patent CN202022087838.2 discloses a multi-axis molten iron transport vehicle with an insulation cover, a transport vehicle body, an iron ladle, and an insulation cover assembly; wherein the iron ladle is arranged in the middle position of the top wall of the transport vehicle body to store the iron ladle for transporting the iron ladle; the insulation cover assembly is transmission-connected to the transport vehicle body, and can be opened and closed at the open end of the iron ladle to selectively seal and insulate the open end of the iron ladle. The transport vehicle selectively seals the open end of the iron ladle through the closable insulation cover assembly to avoid splashing of the iron ladle, thereby avoiding damage to the vehicle and environmental pollution. At the same time, the iron ladle in the iron ladle can be insulated to avoid heat loss of the iron ladle, making the transportation of iron ladle safer and more environmentally friendly. However, the insulation cover assembly lacks effective buffering at the hinge end of the pull rod. When the cover body is docked and the transport vehicle is in motion, the hinge node will be squeezed to a certain extent, affecting the hinge and thus the connection reliability of the insulation cover assembly. Secondly, the cover body mostly adopts a thin-walled structure, and its thermal insulation performance is mainly due to its ability to block hot air, but after its surface is directly heated, it is also directly exposed to the external environment for heat dissipation. The heat dissipation process will take away some heat, especially for the cover body made of metal, so its thermal insulation performance needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Examples, such as Figures 1 to 9As shown, the utility model provides an automatically opening and closing heat preservation cover device, comprising a pair of relatively distributed covers 1, which are respectively a left cover 1a and a right cover 1b, a pull rod 2 is arranged on the side of the cover, a driving cylinder hinged to the side of the pull rod 2 is arranged, and a hinge shaft 4 is arranged at the head end of the pull rod 2. The driving cylinder drives the pull rod 2 to rotate, which can play the role of opening and closing the left cover 1a and the right cover 1b, especially when transporting the tank body, the purpose of environmental protection can be achieved by automatically closing the cover 1. On this basis, the hinge shaft 4 provided by the utility model cooperates with the buffer hinge 5 arranged on the side of the cover body, and the buffer hinge 5 includes a hinge head 51, and the side of the hinge head 51 is connected to the cover body 1 through a welding plate 52. The cross-section of the hinge head 51 is U-shaped, and one end of the hinge head 51 is provided with a hinge interface connected to the head end of the pull rod 2 and the other end is provided with a buffer cavity 54, and a buffer plate 55 and a spring 56 are provided in the buffer cavity 54. The buffer plate 55 is provided with two pairs of contact members 57 on the side facing away from the spring 56. The contact members 57 are movably matched with the slides arranged inside the hinge head 51 and one end thereof faces the hinge shaft 4. Each pair of contact members 57 is clamped in a V-shape with the hinge shaft 4, and waist-shaped holes for fine-tuning the hinge shaft 4 are provided on both sides of the hinge head 51. The cover body 1 includes an outer cover plate 11, and an inner cover plate 12 opposite to the interval is provided inside the outer cover plate 11, and a wall sleeve plate 13 concentrically nested and connected to the outer cover plate 11 is provided at the bottom of the inner cover plate 12.

[0028] Specifically, the device adopts a cover body 1 with a cavity composed of an outer cover plate 11, an inner cover plate 12 and a wall sleeve plate 13, which can block air on the one hand and reduce heat dissipation through the outermost side of the cover body on the other hand, so the thermal insulation performance is good and energy consumption can be reduced. Furthermore, the device adopts a buffer hinge 5 as the connection node between the pull rod 2 and the cover body, and its contact piece 57 forms a V-shaped clamp on the hinge shaft 4, and the waist-shaped hole provides a displacement range for buffering fine-tuning for the hinge shaft 4, and the spring 56 provides elastic support. In this way, during the process of transporting the tank body and at the moment when the driving cylinder performs the closing operation on the cover body, the hinge shaft 4 is subjected to force to compress the spring 56 to deform, and the spring 56 accumulates potential energy and releases it to achieve dynamic balance, thereby playing a buffering role, effectively ensuring the connection reliability between the pull rod 2 and the cover body, and improving the safety of the device. In this way, firstly, the whole opening and closing process of the insulation cover only needs the driver to complete it in the cab, which reduces the involvement of the overhead crane and saves the cost of using the overhead crane; secondly, the production efficiency is improved, the opening and closing process is quick and simple, the production operation time is shortened, the transportation capacity of high-temperature materials is improved, and the exposure time of high-temperature materials in the air is reduced, the energy loss is reduced, and better conditions are created for the subsequent process; thirdly, because the insulation cover is directly arranged on the vehicle, the large-sized insulation cover no longer occupies other production sites. This device is reasonably used for the heat preservation of high-temperature chemical raw materials, high-temperature metals, and other high-temperature materials in liquid or solid state during transportation.

[0029] In order to improve the sensitivity of the contact member 57, the contact member 57 provided by the utility model includes a plurality of integrally welded ring bodies 571, the curved surface of the ring body 571 is slidably matched with the top and bottom surfaces of the slide groove, and a guide rod 572 is provided on one of the ring bodies 571 away from the hinge shaft 4, and the guide rod 572 is plugged into the guide hole 551 provided on the buffer plate 55. In this way, the ring body 571 forms a point-line contact with the slideway, and the friction surface is small, but the plurality of contact points provided by the plurality of ring bodies 571 make the contact member 57 have displacement straightness, and the guiding effect of the guide rod 572 and the guide hole 551 makes the contact member 57 able to respond in time to the external force, and maintain good stability when performing the static clamping action.

[0030] In order to ensure the buffering effect, the utility model is provided with an end cover connected to the buffer cavity 54 by screws at the outer end thereof, and the end cover is used as another supporting surface of the spring 56, and the spring 56 realizes dynamic deformation and recovery between the end cover and the buffer plate 55. It should be noted that the number of springs 56 can be set at will, and at least the movable range of the guide rod 572 must be avoided.

[0031] Considering that the cover plate is generally welded, and the present cover body is composed of a plurality of sheet materials to form a heat-insulating cavity, and in order to facilitate welding, the present utility model is provided with two concentrically distributed semi-annular grooves 14 on the inner top of the outer cover plate 11, and a semi-annular plate 15 matching the semi-annular grooves 14 is provided on the top of the inner cover plate 12, and the cross section of the wall sleeve plate 13 is in a horizontal T-shape and its end is welded to the inner wall of the outer cover plate 11. In this way, while the outer cover plate 11 and the inner cover plate 12 are inserted and sleeved through the semi-annular grooves 14 and the semi-annular plates, sufficient welding surfaces are exposed, namely, the bottom circle of the inner cover plate 12; and after the wall sleeve plate 13 is aligned with the inner cover plate 12, its butt surface with the outer cover plate 11 and the inner cover plate 12 is an effective welding surface, thereby facilitating the welding of the cover body.

[0032] In order to improve the sealing performance of the left cover body 1a and the right cover body 1b, the utility model provides a left blocking plate 16 consistent with the end trajectory at the end of the outer cover plate 11 of the left cover body 1a, and a sealing groove 17 is provided on the end face of the left blocking plate 16; a right blocking plate 18 is provided at the end of the outer cover plate 11 of the right cover body 1b, and a sealing protrusion 19 matching the sealing groove 17 is provided on the end face of the right blocking plate 18. The sealing groove 17 and the sealing protrusion 19 are used to increase the sealing area after the two cover bodies 1 are connected, thereby improving the thermal insulation performance.

[0033] In order to improve the stability after the left cover 1a and the right cover 1b are connected, the utility model provides a plurality of positioning holes 110 on the top of the left blocking plate 16 , and a positioning block 111 cooperating with the positioning holes 110 is provided on the top of the right blocking plate 18 .

[0034] Furthermore, a semi-cylindrical core rod 112 is provided at the center of the cover body 1, a positioning groove 113 is provided on the core rod of the right cover body 1b, and the positioning groove 113 is a vertical elliptical structure, and a positioning column 114 is provided on the core rod of the left cover body 1a to cooperate with the positioning groove 113. In this way, after the left cover body 1a and the right cover body 1b are docked, the positioning port 110 and the positioning block 111, the positioning groove 113 and the positioning column 114 prevent the two covers from rotating relative to each other and moving up and down significantly, thereby improving the sealing performance of the device on the tank body.
