Description

Technical Field

[0001] This utility model belongs to the field of metallurgical material transportation technology, and in particular relates to a defrosting device for an open-top car trunk. Background Technology

[0002] In the material transportation process of metallurgical enterprises, open-top truck containers are widely used for the transfer of bulk materials such as ores and coal. However, in the low-temperature environment of winter, after the open-top container is loaded with ores or coal, the material is prone to sticking and clumping on the inner wall of the container due to the cold temperature. When the vehicle enters the plant to unload, this stuck material is difficult to detach naturally, resulting in a significant reduction in unloading efficiency. Currently, because mechanical cleaning methods can easily cause permanent damage to the structure of the open-top container, enterprises mainly rely on manual cleaning. This not only consumes a lot of time and manpower and has extremely low efficiency, but also significantly increases additional labor costs; especially in winter, the need to thaw the stuck material is more urgent to restore normal transportation processes. Existing thawing devices for open-top truck containers are mostly fixed structures, which have many drawbacks: the disassembly and assembly process is complex and cumbersome, requiring specialized tools and fixed bases; they have poor versatility and are difficult to adapt to open-top container vehicles of different sizes or models; and their thawing efficiency is low, manifested in uneven heating or excessively long thawing time, failing to quickly solve the sticking problem. Furthermore, fixed devices are insufficient to meet periodic or temporary thawing needs, such as during peak periods or sudden transport tasks. Their limited placement also restricts their location, preventing flexible installation in areas with easy vehicle access (such as near unloading points), further hindering overall operational efficiency. These shortcomings of traditional devices not only fail to effectively address the core issue of open-top containers sticking to the bottom in winter, but also result in inconvenient disassembly and reassembly, leading to resource waste and additional costs. This severely violates the efficiency, flexibility, and economy requirements for material transportation in metallurgical enterprises. Therefore, the metallurgical industry urgently needs a device that can be quickly installed and disassembled, is easily reusable, and possesses efficient thawing capabilities. This device should be designed in a modular or mobile form, with installation locations chosen in easily accessible operating areas to seamlessly adapt to the open-top container transfer process. This would efficiently solve the problem of ore and coal sticking to the bottom in winter, avoiding the tedious and time-consuming manual cleaning and the potential damage risks of mechanical cleaning. It would also completely overcome the technical bottlenecks of existing thawing devices, such as inconvenient disassembly and assembly, poor versatility, and lack of reusability, thereby improving the overall efficiency and sustainability of material transportation. Utility Model Content

[0003] This utility model proposes a vehicle open-top box thawing device, which is adapted to the transfer operation process of vehicle open-top boxes and meets the periodic and temporary thawing needs of metallurgical enterprises in production and grassroots material transportation scenarios.

[0004] To achieve the above-mentioned technical objectives, the first objective of this utility model is to provide a defrosting device for an open-top car trunk, comprising: A portal-shaped passageway, comprising several portal frames of the same size, wherein the width of the portal-shaped passageway is greater than the width of the vehicle body, and the length of the portal-shaped passageway is greater than the length of the vehicle body but less than the overall length of the vehicle; adjacent portal frames are connected by crossbars. A roof truss, the lower end of which is inserted into the top of the portal frame; The steam pipeline includes a main pipeline installed on a portal frame, one end of which is connected to a steam source and the other end of which is closed. Multiple branch pipelines are connected to the side wall of the main pipeline, and multiple nozzles are connected to each branch pipeline. A flexible insulation layer is provided, with the portal frame covering both sides, the top, and one port of the portal frame.

[0005] Preferably, a plurality of nozzle supports are provided on the branch pipeline. The nozzle supports are cylindrical in structure, with one end of the nozzle support inserted into the branch pipeline and the nozzle connected to the other end of the nozzle support.

[0006] Preferably, the nozzle support is connected to the branch pipeline by a thread, and the nozzle is inserted into the other end of the nozzle support.

[0007] Preferably, the portal frame includes a vertical tube in the vertical direction and a horizontal tube at the top; the top of the vertical tube and the horizontal tube are connected by fasteners.

[0008] Preferably, each vertical pipe includes several linear pipe fittings, and the top of each linear pipe fitting is connected to the bottom of the upper linear pipe fitting by a fastener.

[0009] Preferably, the canopy truss includes an arched tube, the lower end of which is inserted into the top of the vertical tube.

[0010] Preferably, a support rod is provided at the apex corner of the arched pipe fitting.

[0011] Preferably, the flexible insulation layer includes sidewall insulation layers covering both sides of the portal frame, port insulation curtains covering any end of the portal frame, and top insulation layer covering the top of the portal frame.

[0012] Preferably, the flexible insulation layer is an insulation tarpaulin.

[0013] Preferably, the nozzle is a flat nozzle.

[0014] The advantages and positive effects of this utility model are as follows: This utility model is adapted to the transfer operation process of open-top truck containers, and particularly meets the periodic and temporary thawing needs of metallurgical enterprises in production and grassroots material transportation scenarios, providing an efficient and convenient solution. Its specific implementation method is as follows: When materials inside the open-top cargo box freeze and need thawing, the driver reverses the vehicle into the gate-shaped passageway. The vehicle must enter from the side without the insulated curtain, ensuring the entire cargo box is fully contained within the passageway. Then, the operator turns on the steam source, and high-pressure hot steam is delivered through pre-laid steam pipes, ultimately being forcefully ejected from multiple evenly distributed nozzles. The high-temperature steam from these nozzles directly acts on the surface of the open-top cargo box, achieving a rapid and uniform thawing effect.

[0015] Clearly, the materials do not need to be unloaded during the entire thawing process; the thawing operation can be completed directly inside the carriage, significantly saving time and manpower, and making the operation convenient and quick.

[0016] The portal frame length in this invention is highly flexible and can be easily adjusted according to the length of the actual working vehicle or site limitations. Specifically, to increase the portal length, simply increase the number of portal frames or widen the spacing between adjacent portal frames; conversely, to shorten the portal length, reduce the number of portal frames or decrease their spacing. This design ensures that the portal structure can always be matched with vehicles of different sizes.

[0017] The height of the portal-shaped passageway in this invention can also be flexibly adjusted according to the height of different models of open-top containers. Specifically, the adjustment method is as follows: if the passageway height needs to be increased to accommodate taller containers, the number of linear tubing components forming the passageway sidewalls can be increased; conversely, if the height needs to be reduced, the number of linear tubing components can be decreased. This design ensures that the passageway can adapt to diverse transport equipment and maintain optimal thawing space.

[0018] The portal frame and roof truss in this utility model are connected by a modular plug-in structure. The components can be assembled or disassembled by simple plug-in, without the need for complicated fasteners or special tools. Therefore, the entire system is easy and quick to assemble and disassemble, and can be flexibly arranged according to seasonal needs or relocation. Attached Figure Description

Based on the embodiments of the present utility model, any other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 8 : A vehicle open-top box defrosting device, mainly comprising: A door-shaped passage for accommodating a vehicle compartment, the door-shaped passage comprising several door-shaped frames 1 of the same size, the width of the door-shaped passage being greater than the width of the vehicle compartment, and the length of the door-shaped passage being greater than the length of the vehicle compartment but less than the overall length of the vehicle; The height of the portal frame is greater than the height of the carriage; two adjacent portal frames 1 are connected by crossbars; the capacity of the portal frame cannot be too large, as too large a capacity will increase the consumption of hot steam and reduce the defrosting efficiency, while too small a capacity will make it difficult to reverse into the carriage.

[0024] The lower end of the roof truss 2 is inserted into the top of the portal frame 1; that is, the roof truss 2 and the portal frame 1 are connected by an insertion, which is easier to assemble and disassemble than a fixed connection. Steam pipeline 3, the steam pipeline 3 includes a main pipeline 3-1 installed on the portal frame 1, one end of the main pipeline 3-1 is connected to a steam source, the other end of the main pipeline 3-1 is closed, and multiple branch pipelines 3-2 are connected to the side wall of the main pipeline 3-1, and multiple nozzles 3-3 are connected to each branch pipeline 3-2. Steam pipeline 3 is the core component of this technical solution. It provides high-temperature hot steam to the car roof box, enabling the car roof box to defrost quickly. For safe operation, valve switches can be installed on the gas source pipeline or main pipeline. When there is a risk, the hot steam can be shut off in time. The temperature of the hot steam can be selected according to actual needs.

[0025] A flexible insulation layer is provided, with the portal frame 1 covering both sides, the top, and one port of the portal frame 1.

[0026] To better understand the technical concept of this utility model, a non-limiting description is provided below: To facilitate disassembly, installation, or replacement of the nozzles, several nozzle supports 4 are provided on the branch pipe 3-2. Each nozzle support 4 has a cylindrical structure, with one end inserted into the branch pipe 3-2, and the nozzle 3-3 connected to the other end of the nozzle support 4. The nozzle support 4 is threadedly connected to the branch pipe 3-2, and the nozzle 3-3 is inserted into the other end of the nozzle support 4.

[0027] The portal frame 1 includes a vertical tube in the vertical direction and a horizontal tube at the top; the top of the vertical tube and the horizontal tube are connected by fasteners 1-2. That is, the top of the vertical tube is firmly connected to the horizontal tube by fasteners 1-2, ensuring the stability and load-bearing capacity of the entire frame structure.

[0028] Each vertical pipe includes several linear pipe fittings 1-1. The top of each linear pipe fitting 1-1 is tightly connected to the bottom of the upper linear pipe fitting 1-1 through fasteners 1-2. This design ensures the stability and continuity of the overall structure and is suitable for vertical installation scenarios.

[0029] The canopy truss 2 includes an arched pipe 2-1. The lower end of the arched pipe 2-1 is installed on the top of the vertical pipe via a plug-in connection. This connection design facilitates quick assembly, disassembly, and maintenance. A support rod 2-2 is fixedly installed at the top corner of the arched pipe 2-1. The two ends of the support rod 2-2 are firmly connected to the top corner of the arched pipe 2-1 by welding, effectively distributing external loads and strengthening the overall structural strength and stability of the arched pipe 2-1, preventing deformation or damage under stress.

[0030] The flexible insulation layer includes a side wall insulation layer 5-1 covering both sides of the portal frame 1, a port insulation curtain 5-2 covering any end of the portal frame 1, and a top insulation layer 5-3 covering the top of the portal frame 1.

[0031] The flexible insulation layer is an insulation tarpaulin 5.

[0032] The flexible insulation layer provides comprehensive insulation for the portal frame 1 and comprises the following components: sidewall insulation layer 5-1 covering both sides of the portal frame 1, which adheres tightly to the sidewall surface to prevent heat loss from the sides; port insulation curtain 5-2 covering any end of the portal frame 1, which can be flexibly opened and closed to close the end opening and ensure the insulation performance of the end area; and top insulation layer 5-3 covering the top of the portal frame 1, which evenly covers the top and effectively isolates the influence of external temperatures. These components work together to form a complete flexible insulation system, improving overall thermal insulation efficiency and durability.

[0033] The nozzle 3-3 is a flat nozzle, and the angle of the nozzle can be adjusted by rotating the nozzle.

[0034] Working principle: In practical applications, the gate-shaped passage is first assembled: the gate-shaped frame 1 is connected into a three-dimensional frame with a square grid by fasteners or bolts, and the length, width and height of the frame are adjusted according to the size of the car's convertible top box.

[0035] Next, assemble the plug-in roof truss 2: plug the individual roof truss units in sequence through plugs and slots to form a complete roof frame, and then fix it to the top of the doorway through plugs, hooks or bolts.

[0036] Then install the flat nozzle steam system: make holes at the designed intervals on the branch pipes, where nozzle supports can be installed. Insert the flat steel pipe nozzles into the nozzle supports, adjust the nozzle angle to cover the defrosting area of ​​the car's convertible top box, and then connect the main pipeline to an external steam source.

[0037] Finally, install the thermal tarpaulin assembly: cover the outside of the portal frame and roof truss with the tarpaulin, arrange the tarpaulin to completely cover the sides and top of the portal frame, and then install the curtain at one end of the portal frame, ensuring that the curtain and tarpaulin are sealed and fitted together.

[0038] When defrosting is required, drive the car's convertible top box into the door frame, close the door curtain, turn on the steam source, and spray steam through the flat nozzle. Defrosting will be completed in about 15 minutes. After the operation is completed, disassemble the components in reverse order for easy reuse or storage next time.

[0039] In summary, the plug-in roof truss structure in this application adopts a modular plug-in design, which simplifies the top assembly process. Local units can be quickly connected through standardized interfaces, greatly improving disassembly and assembly efficiency and reducing manual intervention and tool requirements. The flat nozzle steam system, with its unique flat nozzle structure and flexible angle adjustment function, precisely controls the steam injection trajectory and intensity, achieving accurate steam injection and uniform thawing, avoiding local ice residue. The thermal insulation tarpaulin assembly can use high-performance thermal insulation materials to form a sealed thermal insulation space. Combined with the efficient heat conduction of the steam system, the thawing operation of the car roof box can be completed within 15 minutes, significantly improving loading and unloading efficiency and adapting to different operating environments.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
