Description

Technical Field

[0001] The present invention relates to the technical field of transportation, and particularly to a semi-trailer carriage, a semi-trailer frame and a semi-trailer. Background Art

[0002] The semi-trailer carriage is the main part for loading goods to protect the goods from the influence of the external environment. The carriage is usually equipped with a ventilation system to ensure air circulation and prevent the goods from mildewing or deteriorating due to moisture. The semi-trailer frame is the connecting part responsible for supporting the carriage, the goods and the cab, ensuring the stability of the vehicle during driving. The semi-trailer is a highly efficient transportation tool that can achieve large-capacity and long-distance cargo transportation in road transportation, greatly reducing the unit transportation cost. The semi-trailer can be combined with different types of cabs and carriages to adapt to various transportation scenarios and cargo types, with strong flexibility.

[0003] When the existing semi-trailer is driving at high speed, the air flow usually speeds up through the ventilation grille, resulting in the dust carried in the air being more likely to deposit on the grille. If the ventilation grille is not cleaned regularly, the dust will gradually accumulate and finally completely block the ventilation opening, resulting in poor air circulation in the carriage, affecting the temperature and humidity control of the goods, and possibly causing the goods to mildew or deteriorate. Moreover, in rainy weather, rainwater may enter the interior of the carriage from the ventilation grille, which may not only cause the goods to get wet, but also cause the internal structure of the carriage to be corroded by the rainwater, thereby reducing the service life of the carriage.

[0034] Embodiment 1

[0035] Referring to Figures 1 to 7 , for the first embodiment of the present invention, a semi-trailer carriage is provided. This device includes a carriage body 100, which includes a load-bearing component 101, a dust removal component 102 that cooperates to prevent dust from entering the interior of the load-bearing component 101, and a moisture-proof component 103 that prevents water from accumulating inside the load-bearing component 101 on rainy days and at the same time prevents dust from entering the interior of the load-bearing component 101 from the drain outlet; the load-bearing component 101 includes a carriage body 101a, electric doors 101b respectively hinged to both side surfaces of the carriage body 101a, ventilation grilles 101c fixedly installed on the inner surface of the carriage body 101a to prevent goods from mildewing, deteriorating, or accumulating odors, and a distribution box 101d fixedly installed on the outer surface of the carriage body 101a and used in cooperation with the electric doors 101b; it should be noted that the carriage body 101a is the main structure of the entire semi-trailer for carrying goods. The electric doors 101b are electrically connected to the distribution box 101d and are controlled by an electric control switch, thus facilitating the loading and unloading of goods. The ventilation grilles 101c are used to help the carriage body 101a ventilate and prevent the goods inside the carriage body 101a from mildewing, deteriorating, or accumulating odors. The distribution box 101d is used to provide power support for the electric doors 101b.

[0036] The dust removal assembly 102 includes an axial flow impeller 102a disposed above the ventilation grille 101c, a support shaft 102b fixedly connected to the inner surface of the axial flow impeller 102a, a first bevel gear 102c fixedly sleeved on the outer surface of the support shaft 102b, and a second bevel gear 102d meshed with the outer surface of the first bevel gear 102c;

[0037] It should be noted that when the semi-trailer is moving, the air in front of the carriage body 100 is compressed and flows backward, forming a high-speed air flow. This air flow enters the interior of the carriage through the ventilation grille 101c and directly acts on the axial flow impeller 102a installed above the ventilation grille. The design of the axial flow impeller 102a enables it to capture the air flow and convert it into a rotational motion, driving the support shaft 102b to drive the first bevel gear 102c to rotate synchronously, and then the first bevel gear 102c drives the second bevel gear 102d to rotate.

[0038] The moisture-proof assembly 103 includes a water collecting pipe 103a connected to the lower part of the carriage body 101a, a water storage tank 103b connected to the other end of the water collecting pipe 103a, an L-shaped pipe 103c fixedly installed on the inner surface of the water storage tank 103b, a drain pipe 103d connected to the penetrating end of the L-shaped pipe 103c, and a float 103e disposed in the inner cavity of the water collecting pipe 103a.

[0039] It should be further noted that the water collecting pipe 103a is used to guide the accumulated water inside the carriage body 101a to the water storage tank 103b, and through the cooperation of the L-shaped pipe 103c and the drain pipe 103d, it is used to drain the accumulated water.

[0040] Specifically, the outer end face of the support shaft 102b is fixedly installed on the outer surface of the carriage body 101a through a bearing, and the float 103e moves synchronously with the rise and fall of the water level inside the water collecting pipe 103a.

[0041] Furthermore, the dust removal assembly 102 further includes a connecting column 102e fixedly connected to the inner surface of the second bevel gear 102d, a reciprocating roller 102f fixedly sleeved on the outer surface of the connecting column 102e, and a sliding sleeve 102g slidably sleeved on the outer surface of the reciprocating roller 102f.

[0042] It should be explained that the rotational power of the second bevel gear 102d is transmitted to the reciprocating roller 102f through the connecting column 102e, and the sliding sleeve 102g drives the scraper 102h to perform vertical reciprocating movement through the reciprocating roller 102f, thereby removing the dust attached to the surface of the ventilation grille 101c.

[0043] Among them, the dust removal assembly 102 also includes a scraper 102h fixedly connected to the outer surface of the sliding sleeve 102g and used in conjunction with the ventilation grille 101c, a limiting sleeve 102i fixedly connected to the outer surface of the sliding sleeve 102g, and a limiting rod 102j fixedly connected to the outer surface of the compartment 101a and used in conjunction with the limiting sleeve 102i.

[0044] It should be explained that the limiting sleeve 102i and the limiting rod 102j are used to limit the moving range of the sliding sleeve 102g to ensure that the moving path of the scraper 102h is correct.

[0045] Preferably, the outer end surface of the connecting column 102e is fixedly mounted on the outer surface of the compartment 101a through a bearing, the outer surface of the scraper 102h is in sliding contact with the outer surface of the ventilation grille 101c, and the limiting sleeve 102i is slidably mounted on the outer surface of the limiting rod 102j.

[0046] It should be noted that the moisture-proof component 103 also includes a driving rod 103f fixedly connected to the surface of one side of the float 103e close to the L-shaped tube 103c, a transmission rod 103g hinged to the outer surface of the driving rod 103f, and a swing rod 103h hinged to the other end of the transmission rod 103g.

[0047] What should be explained further is that the float 103e can drive the driving rod 103f to move synchronously with the rise and fall of the water level in the water tank 103b. When the water level in the water tank 103b rises, the movement of the driving rod 103f is transmitted to the swing rod 103h through the transmission rod 103g, so that the swing rod 103h drives the plug 103i to move vertically, thereby releasing the blockage of the L-shaped tube 103c and allowing the accumulated water to be discharged smoothly.

[0048] Furthermore, the moisture-proof component 103 also includes a plug 103i hinged to the outer surface of the swing rod 103h and used in conjunction with the L-shaped tube 103c, and a first fixing block 103j and a second fixing block 103k respectively fixedly connected to the two side surfaces of the L-shaped tube 103c.

[0049] Specifically, the outer end surface of the driving rod 103f is rotationally connected to the inner surface of the first fixed block 103j, the outer end surface of the swing rod 103h is rotationally connected to the inner surface of the second fixed block 103k, and the outer surface of the plug 103i is in sliding contact with the inner wall of the L-shaped tube 103c.

[0050] During use, when the semi-trailer is moving, the air in front of the box body 101a is compressed to form a high-speed air flow. The air flow enters the interior of the carriage through the ventilation grille 101c and acts on the axial flow impeller 102a installed above the ventilation grille. The axial flow impeller captures the air flow and converts it into a rotational motion, driving the support shaft 102b, the first bevel gear 102c, and the second bevel gear 102d to rotate. Through the cooperation of the second bevel gear 102d and the connecting column 102e, the power is transmitted to the reciprocating roller 102f, and the sliding sleeve 102g drives the scraper 102h to perform a vertical reciprocating movement along the reciprocating roller 102f, removing the dust attached to the surface of the ventilation grille, thereby self-cleaning the ventilation grille 101c, preventing the ventilation opening from being blocked, and achieving the effect of ensuring the air circulation in the box body 101a and avoiding the mildew of goods or the accumulation of peculiar smells;

[0051] Meanwhile, in rainy weather, the accumulated water in the carriage flows into the water storage tank 103b through the water collecting pipe 103a connected to the lower part of the box body. The float 103e in the inner cavity of the water collecting pipe moves synchronously with the rise and fall of the water level. When the water level rises, the float drives the driving rod 103f to move. The driving rod transmits the motion to the swing rod 103h through the transmission rod 103g, and the swing rod further drives the plug 103i to perform a vertical movement, releasing the blockage of the L-shaped pipe 103c, so that the accumulated water can be smoothly discharged through the L-shaped pipe and the drain pipe 103d, preventing the accumulation of water inside the carriage;

[0052] When the water level drops: the float 103e, the driving rod 103f, the transmission rod 103g, the swing rod 103h, and the plug 103i are reset, so that the plug 103i re-blocks the L-shaped pipe, preventing external dust from entering the interior of the carriage through the drain port 103d, realizing the operation of dust removal and moisture protection for the box body 101a without an additional power source, and achieving the effect of providing a safer and more reliable transportation environment for goods transportation.

[0053] In summary, through the cooperation of the dust removal component 102 and the moisture protection component 103, it is possible to prevent the ventilation grille 101c of the semi-trailer box from being blocked by dust and the problem of water accumulation inside the box body 101a during rainy weather, and without an additional power source, so as to ensure smooth air circulation in the box body 101a, avoid the mildew of goods or the accumulation of peculiar smells caused by poor ventilation, prevent the goods from getting wet, and prevent external dust from entering the interior of the box body 101a.

[0054] Embodiment 2

[0055] Referring to Figure 1 、 Figure 2 and Figure 4 , this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that this embodiment provides a semi-trailer frame and a semi-trailer.

[0056] Furthermore, the vehicle frame body 200 includes a support frame 201 disposed directly below the compartment body 101a, several rear wheels 202 disposed at the bottom of the support frame 201, baffles 203 respectively fixedly connected to both side surfaces of the support frame 201 and used in cooperation with the ventilation grille 101c, a pneumatic telescopic rod 204 adaptively installed at the bottom of the support frame 201, and a connecting member 205 fixedly installed on the outer end surface of the support frame 201;

[0057] The compartment body 101a is fixedly installed on the top of the support frame 201.

[0058] Among them, the support frame 201 is the main structure of the vehicle frame body 200, which is used to support the compartment body 101a and transfer the load to the rear wheels 202. Through its strong frame design, it ensures the stability of the entire semi-trailer during driving and provides an installation basis for other components. The rear wheels 202 bear the vehicle weight and provide driving force, enabling the semi-trailer to drive smoothly. The baffle 203 is used to prevent dust or debris lifted by the rear wheels 202 during driving from entering the interior of the compartment body 101a. The pneumatic telescopic rod 204 uses air pressure to drive and realizes the telescopic function, thereby changing the height of the support frame 201 to meet the requirements of different loading and unloading scenarios.

[0059] Furthermore, the semi-trailer body 300 includes a vehicle head 301 fixedly installed on the outer surface of the support frame 201 through bearings, a cockpit 302 disposed inside the vehicle head 301, and front wheels 303 disposed at the bottom of the vehicle head 301.

[0060] It should be noted that the vehicle head 301 is the power source and control center of the vehicle. The interior of the vehicle head contains core components such as an engine and a transmission system. The vehicle is driven by the coordinated action of the front wheels 303 and the rear wheels 202. The cockpit 302 is used to provide an operating space for the driver, and its interior is equipped with control devices such as a steering wheel, an instrument panel, an accelerator, and a brake. The driver controls the vehicle through these devices. The front wheels 303 are responsible for steering and part of the load bearing, and the direction of the vehicle is adjusted through the steering mechanism. At the same time, they share the vehicle weight with the rear wheels 202.

[0061] During use, the driver controls the driving direction and speed of the vehicle in the cockpit 302 by operating devices such as the steering wheel, accelerator, and brake, and monitors the vehicle status at the same time, so as to achieve the safe and efficient operation of the whole vehicle. When the semi-trailer is running, the vehicle head 301 drives the front wheels 303 and the rear wheels 202 to rotate through its internal power system, driving the whole vehicle to move forward. At the same time, the support frame 201 bears the weight of the compartment body 101a and transfers the load to the ground;

[0062] During the loading and unloading of goods: the height of the compartment body 101a is adjusted by the pneumatic telescopic rod 204 to meet the requirements of different scenarios, and the connecting member 205 realizes the quick connection or separation between the vehicle head 301 and the vehicle frame body 200, improving the operation efficiency;

[0063] In addition, the baffle 203 cooperates with the ventilation grille 101c on the compartment body 101a to prevent dust or debris raised by the rear wheels 202 during driving from entering the interior of the compartment body 101a, ensuring a clean cargo transportation environment.

[0064] In summary, through the connection between the vehicle frame body 200 and the semi-trailer body 300, dust or debris raised by the rear wheels 202 during driving is prevented from entering the interior of the compartment body 101a, optimizing the quality of the cargo transportation environment. The height adjustment function of the vehicle frame body 200 is realized through the pneumatic telescopic rod 204 to improve the loading and unloading efficiency. The connection between the vehicle head 301 and the support frame 201 is facilitated through the connecting piece 205, enabling quick connection or separation and enhancing the operational convenience, thereby significantly improving the safety and reliability provided by the vehicle for cargo transportation.
