Description
Technical Field
[0001] This utility model relates to a heat preservation device, and more particularly to a device that can be installed on a billet transport vehicle to keep steel billets warm, belonging to the technical field of steel billet transfer and heat preservation equipment. Background Technology
[0002] Hot-rolled strip steel is produced by rolling steel billets into products of specific specifications. Before rolling, the steel billets need to be heated in a heating furnace. The steel billets are first transported to a billet transport trolley by a crane, and then transported from the steelmaking plant to the rolling mill by the billet transport trolley. The transport time of the steel billets on the billet transport trolley is relatively long, which causes a large amount of heat to be lost during the transport process. This will increase the burden on the heating furnace and production costs. Moreover, if the temperature drop is too large, it will also affect the quality of the steel billet itself. Therefore, a heat preservation device that can be installed on the billet transport trolley is needed to keep the steel billets warm during transport and minimize the loss of heat from the steel billets. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat preservation device for steel billets, which can effectively preserve the steel billets.

The baffle is installed on the top surface of the rectangular heat preservation cover near the shorter side. The upper plate is installed on the vertical sidewall of the rectangular heat preservation cover away from the baffle. The pusher plate is installed on the vertical sidewall of the longer side of the rectangular heat preservation cover. Multiple heat insulation plates are installed within the upper plate.
[0006] The aforementioned heat preservation device for transporting steel billets has a rectangular heat preservation cover with a three-layer structure. The inner and outer layers are both made of weathering steel, and the middle layer is made of heat preservation cotton, which is fixed by wire mesh. Rivets are used to fix the device by passing through the outer layer, the middle layer and the outer layer in sequence.
[0007] The aforementioned heat preservation device for transferring steel billets includes an upper plate comprising long guide bars, a square bin, a pusher mechanism, and a top plate mechanism. Two long guide bars are respectively positioned on the long sides of the top surface of the rectangular heat preservation cover. The length direction of the long guide bars is parallel to the length direction of the rectangular heat preservation cover. Slide grooves are provided along the length direction of the two long guide bars on their respective end faces where they are close to each other. The square bin is positioned on the vertical sidewall of the rectangular heat preservation cover away from the baffle bars. The square bin has a hollow interior, and strip-shaped holes are provided on two opposing sidewalls along the length direction of the long guide bars. The two strip-shaped holes are aligned along the length direction of the long guide bars, and their ends are aligned with the slide grooves of the two long guide bars. The pusher mechanism is positioned on the top surface of the square bin, and the top plate mechanism is positioned on the bottom surface of the square bin.
[0008] The aforementioned heat preservation device for steel billet transfer includes a pusher mechanism comprising a first electric cylinder and a long pusher plate. The first electric cylinder is disposed on the top surface of the square chamber, and the length direction of its piston rod is parallel to the length direction of the long guide bar. One end of the long pusher plate is inserted into a strip-shaped hole on the end face of the square chamber away from the long guide bar, and the other end of the long pusher plate is connected to the end of the piston rod of the first electric cylinder via a bracket.
[0009] The above-mentioned heat preservation device for transferring steel billets includes a top plate mechanism comprising a second electric cylinder and a lifting plate; the second electric cylinder is disposed on the bottom end face of the square bin, and the end of its piston rod passes through the side wall of the bottom end face of the square bin; the lifting plate is located inside the square bin, and the end of the piston rod of the second electric cylinder is connected to the bottom end face of the lifting plate; the heat insulation plate is located inside the square bin and is located above the lifting plate.
[0010] In the above-mentioned heat preservation device for steel billet transfer, the length of the heat insulation plate in the width direction of the rectangular heat preservation cover is equal to the maximum distance between the inner walls of the long guide rail grooves on both sides; the thickness of the heat insulation plate is equal to the length of the inner wall of the long guide rail groove in the vertical direction.

Detailed Implementation
[0017] See Figure 1 , 2 and Figure 3 This utility model includes a baffle 1, an upper plate, a pusher plate, a rectangular heat insulation cover 2, and heat insulation plates 3. The rectangular heat insulation cover 2 is set on the top platform of the billet transport vehicle 4, and the length direction of the rectangular heat insulation cover 2 is parallel to the length direction of the billet transport vehicle 4. Both the top and bottom ends of the rectangular heat insulation cover 2 are open. The billet enters and exits through the open top of the rectangular heat insulation cover 2, that is, the billet enters through the open top of the rectangular heat insulation cover 2 and falls onto the billet transport vehicle 4. The baffle 1 is set on the side of the top surface of the rectangular heat insulation cover 2 near the short side. The upper plate is set on the vertical side wall of the rectangular heat insulation cover 2 away from the baffle 1. The pusher plate is set on the vertical side wall of the long side of the rectangular heat insulation cover 2. There are multiple heat insulation plates 3, and they are all set inside the upper plate.
[0018] The rectangular heat insulation cover has a three-layer structure. The inner and outer layers are both made of weathering steel, and the middle layer is made of heat insulation cotton, which is fixed by wire mesh. Rivets pass through the outer layer, the middle layer and the inner layer in sequence for fixation. Weathering steel has excellent high temperature resistance, and the heat insulation cotton can play a role in heat preservation.
[0019] The upper plate includes long guide bars 5, a square compartment 6, a push plate mechanism, and a top plate mechanism. There are two long guide bars 5, each positioned on one of the long sides of the top surface of the rectangular insulation cover 2. The heat insulation plate 3 can slide between the two long guide bars 5, with both ends of the heat insulation plate 3 slidingly within the grooves of the long guide bars 5 on both sides. The length direction of the long guide bars 5 is parallel to the length direction of the rectangular insulation cover 2. Grooves are provided along the length direction on the end faces of the two long guide bars 5 that are close to each other, allowing the heat insulation plate 3 to slide. The square compartment 6 is located on the vertical sidewall of the rectangular insulation cover 2 away from the baffle 1. The square compartment 6 has a hollow structure, and its two opposite sides along the length direction of the long guide bars 5... The walls are provided with strip-shaped holes. Two strip-shaped holes are aligned along the length of the long guide bar 5, and the two ends of the strip-shaped holes are aligned with the sliding grooves of the two long guide bars 5 respectively. The alignment means that the heat insulation plate 3 can smoothly slide out of the strip-shaped hole in the square compartment 6 into the sliding groove of the long guide bar 5. When the heat insulation plate 3 is in the square compartment, it leaves the square compartment through the strip-shaped hole and finally falls between the sliding grooves of the two long guide bars 5. The push plate mechanism is set on the top surface of the square compartment 6, and the top plate mechanism is set on the bottom surface of the square compartment 6. The top plate mechanism is used to lift each heat insulation plate 3 to the same height as the strip-shaped hole in the square compartment, and the push plate mechanism is used to push the heat insulation plate 3 in the square compartment out of the strip-shaped hole in the square compartment until the heat insulation plate 3 is pushed between the sliding grooves of the two long guide bars 5.
[0020] The pusher mechanism includes a first electric cylinder 7 and a long pusher plate 8. The first electric cylinder 7 is located on the top surface of the square compartment 6, and the length direction of its piston rod is parallel to the length direction of the long guide bar 5. One end of the long pusher plate 8 is inserted into the strip-shaped hole on the end face of the square compartment 6 away from the long guide bar 5, and the other end of the long pusher plate 8 is connected to the end of the piston rod of the first electric cylinder 7 through a bracket. The first electric cylinder 7 can drive the long pusher plate 8 to slide. During the sliding process, the long pusher plate 8 pushes the heat insulation plate of the square compartment completely into the groove between the two long guide bars through the strip-shaped hole. By pushing them one by one, the heat insulation plates contact each other and push forward until the first heat insulation plate touches the baffle bar 1. At this time, the rectangular heat insulation cover 2 is closed.
[0021] The top plate mechanism includes a second electric cylinder 9 and a lifting plate 10; the second electric cylinder 9 is disposed on the bottom end face of the square compartment 6, and the end of its piston rod passes through the side wall of the bottom end face of the square compartment 6; the lifting plate 10 is located inside the square compartment 6, and the end of the piston rod of the second electric cylinder 9 is connected to the bottom end face of the lifting plate 10; the heat insulation plate 3 is located inside the square compartment 6 and is located above the lifting plate 10; the second electric cylinder 9 provides an upward force to the lifting plate 10, so that each heat insulation plate arranged on the lifting plate 10 is lifted, and when the uppermost heat insulation plate is pushed between two long guide bars, the next heat insulation plate is raised and aligned with the strip-shaped hole of the square compartment.
[0022] The length of the heat insulation plate 3 in the width direction of the rectangular heat insulation cover 2 is equal to the maximum distance between the inner walls of the sliding grooves of the long guide bars 5 on both sides. This ensures that the heat insulation plate 3 can slide between the sliding grooves of the two long guide bars 5. The thickness of the heat insulation plate 3 is equal to the length of the inner wall of the sliding groove of the long guide bar 5 in the vertical direction. This ensures that the heat insulation plate 3 can slide smoothly in the sliding groove of the long guide bar and minimizes the gap between the heat insulation plate 3 and the sliding groove, thereby reducing the heat loss in the cavity.
[0023] The push plate section includes a motor 11, a lead screw, a lead screw nut 12, and a vertical plate 13. The motor 11 is mounted on the side wall of the square compartment 6, and the vertical plate is mounted on the side wall of the rectangular insulation cover 2. One end of the lead screw is connected to the output shaft of the motor 11, and the other end is connected to the vertical plate. The axis of the lead screw is parallel to the length direction of the rectangular insulation cover 2. The lead screw is located on one side of the rectangular insulation cover 2, and the motor 11 and the vertical plate are located on the same side of the rectangular insulation cover 2. The lead screw nut 12 is mounted on the lead screw. The vertical plate 13 is connected to the lead screw nut 12 via a bracket. The motor 11 drives the lead screw to rotate. The rotating lead screw drives the lead screw nut to move along the axis of the lead screw. The lead screw nut 12 drives the vertical plate 13 to slide synchronously. The sliding vertical plate 13 pushes the heat insulation plate back into the square compartment in sequence. The baffle 1 has a square notch at the center of its end face near the square compartment 6, and the vertical plate 13 is located in the square notch of the baffle 1. When the heat insulation plate moves to the end, the vertical plate 13 is located in the square notch of the baffle 1. This function is to reduce the gap between the heat insulation plate and the baffle 1, and to avoid the presence of the vertical plate 13 causing a gap between the heat insulation plate and the baffle 1, so as to minimize the heat loss in the closed cavity.
[0024] Operating principle:
[0025] This device has two states: the first is the transport and insulation state, and the second is the loading and unloading state. In the transport and insulation state, each heat insulation board 3 is tightly laid on the rectangular heat insulation cover 2. In the loading and unloading state, the heat insulation board 3 is stored in the square bin 6.
[0026] When the heat insulation plates 3 are laid on the rectangular heat insulation cover 2 and need to be collected in the square chamber 6, the piston rod of the first electric cylinder is in the maximum extended state. At this time, the end of the long push plate is located in the strip hole of the square chamber, and the long push plate is not located in the cavity inside the square chamber. The motor drives the lead screw to rotate, and the lead screw nut moves under the drive of the rotating lead screw. The lead screw nut drives the vertical plate 13 to move synchronously, thereby pushing the heat insulation plate 3 pressed against the baffle 1 to move towards the square chamber 6. The heat insulation plates 3 are pushed into the square chamber 6 in sequence. During this process, the second electric cylinder drives the lifting plate 10 to slowly descend. The first heat insulation plate 3 that enters the square chamber 6 falls onto the lifting plate 10, and the subsequent heat insulation plates fall onto the previous heat insulation plate in sequence until all the heat insulation plates fall into the square chamber.
[0027] When all the heat insulation panels 3 are located inside the square compartment, if it is necessary to lay the heat insulation panels 3 on the rectangular insulation cover 2, operate the motor 11 to move the vertical plate 13 into the square notch of the baffle 1; then start the first electric cylinder 7 to repeatedly extend and retract its piston rod. During this process, the long push plate 8 continuously pushes the heat insulation panels 3 in the square compartment 6 into the space between the two long guide bars 5. During the repeated operation of the first electric cylinder 7, the second electric cylinder 9 drives the lifting plate 10 to move upward; the first electric cylinder 7 retracts its piston rod, at which point the long push plate 8 pushes the heat insulation panels into the space between the long guide bars, and then the first electric cylinder extends its piston rod to its maximum length. At this time, the lifting plate 10 pushed by the second electric cylinder drives the remaining heat insulation panels to move upward to fill the space in front of the strip hole at the top of the square compartment, waiting for the next push of the long push plate 8. This process is repeated until all the heat insulation panels are pushed out of the square compartment.
