Description

Technical Field

[0001] This utility model belongs to the field of hot steel billet transportation technology, and specifically relates to a heat preservation device for a sealed heat preservation vehicle for steel billets. Background Technology

[0002] Due to site limitations, hot rolling of hot steel billets is generally carried out in different locations. Steel companies can transport the hot steel billets produced in the converter to the rolling line by means of roll line or road transport. However, since roll line transportation requires reasonable workshop layout and production scheduling, which is difficult for many steel mills in China, road transport is currently the most commonly used method for transporting hot steel billets in China.

[0003] Currently, in order to reduce costs, increase efficiency, and achieve ultra-low emissions, steel companies are paying increasing attention to the heat loss during the transportation of hot steel billets. They usually use insulated trucks for transporting hot steel billets. The insulated boxes of current hot steel billet transport insulated trucks are usually of a reversible opening structure, with asbestos fiber blankets laid flat on the inside of the two sides of the box as the insulation layer. Although the installation process of this insulation layer is simple, it has problems such as easy for the insulation layer to fall off, high maintenance and replacement costs, and poor insulation effect. Utility Model Content

[0004] The purpose of this utility model is to provide a heat preservation device for a sealed heat preservation car for steel billets, thereby overcoming the shortcomings of existing technologies that use flat-laid asbestos fiber blankets as the insulation layer, resulting in easy detachment of the insulation layer, high maintenance and replacement costs, and poor insulation effect. The specific technical solution is as follows:

[0005] A heat preservation device for a steel billet sealed insulated truck includes an insulated half-box symmetrically mounted on both sides of a trailer platform. The inner side of each insulated half-box has an insulation structure, which includes insulated folding blocks, fixed partitions, reinforcing bar fixing rings, threaded reinforcing bar rods, and L-shaped edge sealing plates. The fixed partitions are evenly distributed on the inner side of the insulated half-box, with each row of fixed partitions connected by a threaded reinforcing bar rod. The insulated folding blocks are positioned between two fixed partitions, with both front and rear end faces abutting against the fixed partitions. The L-shaped edge sealing plates are used to sew together adjacent rows of insulated folding blocks. The reinforcing bar fixing rings are inserted into adjacent adjacent rows of insulated folding blocks to press the L-shaped edge sealing plates tightly.

[0006] Preferably, the insulated semi-box includes side panels, a top panel, and a rear panel that are perpendicularly joined together.

[0007] Preferably, a reinforcing inclined pad is provided between the top plate of the compartment and the side plate of the compartment.

[0008] Preferably, the side panels, top panels, and tail panels of the compartment are provided with limiting protrusions on their outward-facing edges, and the limiting protrusions abut against the heat-insulating folding blocks.

[0009] Preferably, the front and rear ends of the L-shaped edge sealing steel plate are connected to the limiting protrusion by bolts.

[0010] Preferably, one end of the steel threaded rod is welded to the inner side of the insulated half-box, and the other end passes through the limiting protrusion to be installed on the limiting protrusion.

[0011] Preferably, the insulated semi-box is also provided with a rainproof assembly, which includes a first rainproof plate and a second rainproof plate respectively disposed on the top plate of the box. The first rainproof plate and the second rainproof plate are obliquely crossed each other, with one rainproof plate located above the other so that it appears as an "I" shape when viewed from the side.

[0012] Preferably, the heat-insulating folding block is made of high-purity aluminum silicate fiber.

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

[0014] 1. The present invention provides a heat preservation device for a steel billet sealed heat preservation vehicle. By laying several heat preservation folded blocks in a fully stacked structure on the inner side of the half box to form a heat preservation layer, the heat preservation effect of the heat preservation layer is improved. The heat preservation folded blocks are positioned, fixed and sealed by fixed partitions, L-shaped edge sealing steel plates, steel bar fixing rings and steel bar threaded rods to prevent the heat preservation structure from loosening and warping during use.

[0015] 2. This utility model adopts a stacked and assembled insulation structure (insulation layer). When the insulation effect of a certain insulation fold block is not good, only the corresponding insulation fold block needs to be replaced, which reduces the maintenance and replacement cost of the insulation layer. It solves the technical problems of easy detachment of the insulation layer, high maintenance and replacement cost and poor insulation effect caused by the installation process of using flat asbestos fiber blanket as the insulation layer in the existing technology.

[0016] 3. The insulation device for the insulated vehicle provided by this utility model is further provided with mutually diagonally intersecting rain shields on the top plate of the compartment. The rain shields are detachably installed above the assembled insulated compartment to block rain from the joints and prevent rainwater from seeping in through the joints and affecting the use of the insulation layer.

[0029] Preferably, the inner side of the insulated semi-box 200 is provided with an insulation structure 300. The insulation structure 300 includes an insulation folding block 310, a fixed partition 320, a reinforcing bar fixing ring 330, a reinforcing bar threaded rod 340, and an L-shaped edge sealing steel plate 350.

The reinforcing bar fixing ring 330 is inserted into two adjacent rows of adjacent insulation folding blocks 310 to press the L-shaped edge sealing steel plate 350 tightly.

[0030] In some preferred embodiments, the insulated semi-box 200 includes mutually perpendicularly spliced ​​side panels 210, a top panel 220, and a rear panel 230. It is worth noting that the two insulated semi-boxes 200 are specifically symmetrical about the longitudinal axis of the trailer platform 100, and each of the two insulated semi-boxes 200 is hinged to the long side of the trailer platform 100.

[0031] Each inner sidewall of the insulated semi-box 200 is provided with a plurality of insulated folding blocks 310, and the plurality of insulated folding blocks 310 form an insulation layer in a fully stacked structure. Each fixed partition 320 is disposed between two insulated folding blocks 310 and abuts against the insulated folding blocks 310.

[0032] In some preferred embodiments, a reinforcing inclined pad 240 is provided between the top plate 220 and the side plate 210 of the compartment. The purpose of the reinforcing inclined pad 240 is to better transition the insulation structure 300 installed at the junction of the inner wall of the two insulated half-boxes 200.

[0033] In some preferred embodiments, limiting protrusions 250 are provided on the outward-facing edges of the side panels 210, top panels 220, and rear panels 230 of the compartment, and the limiting protrusions 250 abut against the insulated folding blocks 310. The front and rear ends of the L-shaped edge sealing steel plate 350 are connected to the limiting protrusions 250 by bolts. One end of the threaded steel bar 340 is welded to the inner side of the insulated half-box 200, and the other end passes through the limiting protrusions 250 to be installed on the limiting protrusions 250. The limiting protrusions 250 are provided to both block and limit the edges of the insulated folding blocks 310 and to facilitate the installation of the L-shaped edge sealing steel plate 350.

[0034] Preferably, the insulating folding blocks 310 are all made of high-purity aluminum silicate fiber to improve the insulation performance of the insulating box.

[0035] In some preferred embodiments, a plurality of threaded steel bars 340 are connected to each of the limiting protrusions 250. The threaded steel bars 340 penetrate vertically through the limiting protrusions 250, the plurality of thermal insulation folding blocks 310, and the plurality of fixed partitions 320 to enhance the connection stability between the thermal insulation folding blocks 310 and the thermal insulation half-box 200, while ensuring the neatness of the installation of the thermal insulation folding blocks 310 and facilitating subsequent replacement and disassembly.
