Description

Technical Field

[0001] This utility model belongs to the field of dangerous goods transportation technology, specifically relating to a fireproof board for dangerous goods transport compartments that is easy to assemble and disassemble. Background Technology

[0002] As carriers of flammable, explosive, and corrosive hazardous materials, dangerous goods transport vehicles have extremely stringent requirements for the protective performance and ease of maintenance of their inner fireproof panels. Currently used fireproof panels in the industry suffer from two major drawbacks: First, low installation and disassembly efficiency and high maintenance costs. Existing fireproof panels are mostly fixed with bolts or welded, requiring specialized tools such as wrenches and welding machines for both installation and disassembly, making the process complex. When a fireproof panel is partially damaged due to cargo collisions, the damaged panel cannot be replaced individually; the entire panel must be removed and reinstalled. Second, poor splicing and sealing performance, posing significant safety hazards. Traditional fireproof panels often use flat, straight-edge splicing, which easily leads to gaps due to installation errors or long-term vibration. In the event of a fire inside the vehicle, flames and toxic fumes can spread rapidly through these gaps. Therefore, there is an urgent need for a fireproof panel for dangerous goods transport vehicles that allows for rapid installation and disassembly and provides reliable splicing and sealing. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model provides a fireproof panel for dangerous goods transport vehicles that is easy to assemble and disassemble, thereby solving the problems mentioned in the background technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A fireproof panel for a hazardous materials transport vehicle that is easy to assemble and disassemble includes a panel assembly. One side of the panel assembly has a dovetail protrusion, and the other side of the panel assembly has a dovetail groove. The bottom of the dovetail groove has multiple locking holes, and a cam locking mechanism is provided in the locking holes. The upper side of the panel assembly has an upper insert block, and the lower side of the panel assembly has an insert block groove. The cam locking mechanism is located between the upper insert block and the dovetail groove.

[0006] Furthermore, the plate assembly includes a base plate, a rock wool fireproof layer on the upper side of the base plate, a high-temperature resistant fireproof layer on the upper side of the rock wool fireproof layer, and a buffer layer on the lower side of the base plate.

[0007] Furthermore, the cam locking mechanism includes a tightening block connected to the base plate, a rotating shaft on the lower side of the tightening block, a plurality of cams on the rotating shaft, a locking shaft on the cam, a locking boss on the lower side of the locking shaft, a spring on the outer side of the locking shaft, one end of the spring being connected to the locking boss, and an internal hexagonal screw hole on the tightening block.

[0008] Furthermore, the dovetail protrusion is provided with multiple limiting grooves, which are adapted to the upper side of the locking shaft.

[0009] Furthermore, the lock hole is connected to the upper end of the locking shaft, and a boss hole is provided on the lower side of the lock hole, which is adapted to the locking boss.

[0010] Furthermore, the substrate has a dovetail boss on one side, a dovetail groove on the other side, an upper insertion block on the upper side, an insertion block groove on the lower side, and a cam locking mechanism on the substrate.

[0011] Furthermore, the rock wool fireproof layer uses rock wool fireproof core material, the high-temperature fireproof layer has a high-temperature ceramic coating on the surface, the substrate is galvanized steel plate, and the buffer layer is made of flame-retardant rubber material.

[0012] Furthermore, the dovetail groove and the insert groove are provided with a sealing flame-retardant strip, which is made of expanded graphite.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] 1. Through the precise fit between the dovetail boss and the dovetail groove, combined with the quick locking and releasing function of the cam locking mechanism, the installation and removal of a single fireproof panel can be completed quickly with simple tools. When local damage occurs, the damaged panel can be replaced individually, avoiding the material waste caused by complete removal, significantly shortening maintenance time, and reducing maintenance costs and downtime losses for hazardous materials transport vehicles;

[0015] 2. The dovetail structure, combined with expanded graphite sealing strips, forms a tight seal under normal conditions through mechanical extrusion, effectively blocking external moisture and dust. In the event of a fire, the expanded graphite expands upon heating, further sealing any gaps and preventing the spread of flames and toxic fumes. This multi-layered sealing design meets the stringent safety standards for the transport of dangerous goods, significantly improving the fire protection level of the vehicle compartment.

[0016] 3. A galvanized steel base plate ensures structural strength, while a rock wool fireproof layer and a high-temperature resistant ceramic coating form a double fire barrier. A flame-retardant rubber buffer layer reduces impact damage. The synergistic effect of these layers gives the fireproof board impact resistance, high-temperature resistance, and strong flame retardancy. The modular design adapts to different sized carriages, offering high versatility and meeting the protection requirements for various types of dangerous goods transportation.

[0029] The panel assembly 1 includes a base plate 11, a rock wool fireproof layer 12 on the upper side of the base plate 11, a high-temperature resistant fireproof layer 13 on the upper side of the rock wool fireproof layer 12, and a buffer layer 14 on the lower side of the base plate 11. The rock wool fireproof layer 12 uses rock wool fireproof core material, the high-temperature resistant fireproof layer 13 has a high-temperature resistant ceramic coating on the surface, the base plate 11 is a galvanized steel plate, and the buffer layer 14 is made of flame-retardant rubber material.

[0030] Specifically, the base plate 11 is made of galvanized steel plate, providing strong support and corrosion resistance for the whole; the upper rock wool fireproof layer 12 achieves Class A flame retardancy with rock wool core material; the high-temperature fireproof layer 13 above it is a ceramic coating that can withstand high-temperature flames; and the lower buffer layer 14 is flame-retardant rubber that can buffer the impact of goods collisions. The four-layer structure works together to ensure the structural strength of the fireproof board and achieve multiple protections such as fire resistance, high temperature resistance, and impact resistance.

[0031] The cam locking mechanism 2 includes a tightening block 21 connected to the base plate 11. A rotating shaft 23 is provided on the lower side of the tightening block 21. Multiple cams 22 are provided on the rotating shaft 23. A locking shaft 25 is provided on the cam 22. A locking boss 26 is provided on the lower side of the locking shaft 25. A spring 24 is provided on the outer side of the locking shaft 25. One end of the spring 24 is connected to the locking boss 26. An internal hexagonal screw hole is provided on the tightening block 21.

[0032] Specifically, the tightening block 21 has an internal hexagonal screw hole for easy rotation with tools; the rotating shaft 23 drives multiple cams 22 to rotate synchronously, the cams press the locking shaft 25 upward, and the spring 24 is compressed; the upper end of the locking shaft 25 is inserted into the limiting groove 41, and the locking boss 26 is engaged with the boss hole 52 to achieve locking. Reverse rotation resets the spring and unlocks, enabling quick assembly and disassembly.

[0033] The dovetail boss 4 is provided with multiple limiting grooves 41, which are adapted to the upper side of the locking shaft 25. The locking hole 51 is connected to the upper end of the locking shaft 25, and the lower side of the locking hole 51 is provided with a boss hole 52, which is adapted to the locking boss 26.

[0034] Specifically, the dovetail boss 4 can be embedded in the dovetail groove 5 of the adjacent plate, and its upper positioning groove 41 is precisely matched with the upper end of the locking shaft 25 to ensure lateral positioning; the locking hole 51 allows the locking shaft 25 to pass through, and the lower boss hole 52 cooperates with the locking boss 26 to limit the radial movement of the locking shaft and ensure the stability of the structure after splicing.

[0035] The substrate 11 has a dovetail boss 4 on one side and a dovetail groove 5 on the other side. An upper insertion block 3 is located on the upper side of the substrate 11, and an insertion block groove 6 is located on the lower side. A cam locking mechanism 2 is also provided on the substrate 11. Specifically, the dovetail boss 4 on one side of the substrate 11 and the dovetail groove 5 on the other side cooperate to achieve horizontal splicing; the upper insertion block 3 on the upper side and the insertion block groove 6 on the lower side are connected to complete longitudinal positioning; the cam locking mechanism 2 is installed on the substrate to firmly lock the spliced ​​panels. The overall design allows for modular assembly of the panels, adapting to different carriage sizes.

[0036] The dovetail groove 5 and the insert groove 6 are equipped with sealing flame-retardant strips made of expanded graphite. Specifically, the inner walls of the dovetail groove 5 and the insert groove 6 are both provided with sealing grooves, and the sealing flame-retardant strips made of expanded graphite are embedded in the sealing grooves. When splicing, the sealing flame-retardant strips are squeezed by the dovetail protrusion 4 or the upper insert 3, tightly fitting the gaps. The expanded graphite sealing flame-retardant strips are sealed under normal conditions, and expand and seal the gaps when exposed to high temperatures, thus enhancing the fireproof sealing performance.

[0037] Operating principle: Based on the inner wall dimensions of the dangerous goods transport vehicle, prefabricate fireproof board units of corresponding specifications to ensure the dimensional accuracy of dovetail bosses 4, dovetail grooves 5, upper inserts 3, and insert grooves 6; check the structure of each layer: rock wool fireproof layer 12 has no hollow areas, high-temperature fireproof layer 13 has no missing coating, and buffer layer 14 has no damage; confirm that the cam locking mechanism 2 rotates smoothly, the spring 24 has normal elasticity, and the sealing flame retardant strip is completely embedded in the sealing groove.

[0038] The first fireproof board is temporarily fixed to the reference position on the inner wall of the carriage using a positioning pin. The second fireproof board is taken, and its dovetail protrusion 4 is aligned with the dovetail groove 5 of the first fireproof board. It is slowly pushed in horizontally until the dovetail protrusion 4 is fully embedded in the dovetail groove 5. At this time, the limiting groove 41 and the locking hole 51 are coaxially aligned. The tightening block 21 of the second fireproof board is rotated clockwise, which drives the cam 22 to rotate. The cam 22 presses the locking shaft 25 to move upward, and the spring 24 is compressed until the top of the locking shaft 25 is fully embedded in the limiting groove 41. The tightening block 21 is rotated to the limiting position to complete the horizontal splicing and locking. The third fireproof board is taken, and its lower insert groove 6 is aligned with the upper insert 3 on the upper side of the second fireproof board. It is fitted vertically downward to achieve longitudinal positioning. The horizontal splicing steps are repeated to splice and lock the dovetail protrusion 4 of the third fireproof board with the dovetail groove 5 of the adjacent fireproof board. At this time, the sealing flame-retardant strip in the dovetail groove 5 and the insert groove 6 are compressed to form an initial seal.

[0039] When a fireproof panel is damaged, turn the tightening block 21 of the fireproof panel counterclockwise. The cam 22 releases the locking shaft 25, and the spring 24 pushes the locking shaft 25 down to disengage from the limiting groove 41. Pull out the damaged fireproof panel horizontally, and the damaged panel can be removed. After replacing the new fireproof panel, repeat the splicing and locking steps to complete the maintenance. The time for a single replacement can be controlled within 15 minutes.
