Description

Technical Field

[0001] This utility model relates to the field of semi-trailer frame technology, specifically to a side-tipping semi-trailer unloading structure. Background Technology

[0002] As the core carrier of bulk commodity road transportation, the structural design and synergy of the unloading system of semi-trailers directly determine logistics efficiency. The vehicle body is based on a high-strength load-bearing frame, integrating suspension, braking, and traction connection devices to adapt to diverse cargo forms such as bulk, packaged, and viscous materials. Semi-trailers typically unload materials using side-discharge and rear-discharge methods, balancing cargo flow characteristics with operational constraints. This requires controlling the dumping rhythm of bulk materials through guide structures, providing a smooth discharge path for viscous materials, and avoiding space limitations in narrow spaces.

[0003] According to the authorization announcement number (CN221113656U), a side-tipping mechanism for a dump semi-trailer includes a frame assembly, a platform, a cargo box, and two sets of doors. The two sets of doors are respectively installed on the left and right sides of the cargo box. The platform is fixedly installed on the frame assembly, and the cargo box is placed on the platform. During unloading operations, the left door of the cargo box is unlocked and opened. Then, an upward lifting force is applied to the right side of the cargo box through a lifting mechanism, causing the cargo box to tilt to the left around its support point. Gravity then drives the material inside the cargo box to slide to the left along the tilt direction, thereby completing the unloading operation.

[0004] The structure disclosed in this patent has defects in practical applications, specifically as follows: For highly fluid materials, unloading via only opening a single-side door and tilting the carriage lacks an outlet adjustment structure, making it impossible to control the material flow rate and direction. This easily leads to uncontrolled spillage, causing the unloading position to deviate, material to scatter outside the target area, damaging the site and increasing cleanup costs. High-speed flowing materials can also impact the ground, damage equipment, and even injure personnel when splashing, amplifying safety risks. Furthermore, because the flow rate cannot be controlled, in scenarios requiring quantitative batch unloading, over- or under-discharge is highly likely, affecting both measurement accuracy and operational efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a side-tipping semi-trailer unloading structure, which addresses the problem in the existing technology that the flow rate and direction of highly fluid materials cannot be controlled during side-tipping unloading, easily leading to uncontrolled spillage, resulting in position deviation, impact damage, and metering difficulties, as well as increased cleaning costs and safety risks. The proposed solution can improve the control of the flow rate and direction of highly fluid materials, avoiding uncontrolled spillage.

[0006] This utility model is achieved through the following technical solution:

[0007] A side-tipping semi-trailer unloading structure includes: a frame body; a cargo box body with a main unloading port, one side of the bottom of the cargo box body being rotatably connected to the frame body, and the other side of the bottom of the cargo box body being supported on the frame body; multiple partition frames, which are spaced apart at the main unloading port, forming a secondary unloading port between adjacent partition frames; multiple flow regulating components, which are installed at corresponding secondary unloading ports, and the flow regulating components can adjust the flow area of ​​the secondary unloading ports; and a drive component, which is installed on the frame body and can drive the cargo box body to rotate to achieve the side-tipping action.

[0008] Furthermore, in this utility model, the above-mentioned flow regulation component includes: multiple regulating gates, which are distributed sequentially along the height direction of the discharge port, with adjacent regulating gates rotatably connected, the uppermost regulating gate installed between two partition frames, and the lowermost regulating gate detachably connected to the bottom of the cargo box body; wherein, a preset number of regulating gates can be flipped outward to the open state, thereby controlling the material to be discharged at a preset discharge flow rate.

[0009] Furthermore, in this utility model, a plurality of gate lock seats are installed at the bottom end of the cargo box body along the extending direction, and the gate lock seats are provided with locking through holes; a gate attachment is installed on the outer wall of the lowest adjusting gate, and an installation groove is provided on the gate attachment. A first elastic member is installed in the installation groove, and a locking pin is connected to the free end of the first elastic member. The locking pin can be engaged into the corresponding locking through hole under the action of the first elastic member, thereby realizing the locking of the adjusting gate.

[0010] Furthermore, in this utility model, the above also includes a linkage locking pin; at least one gate linkage sleeve is installed on the regulating gate plate, and the gate linkage sleeves of two adjacent regulating gate plates can be coaxially aligned; the linkage locking pin can be inserted into the gate linkage sleeves of two adjacent regulating gate plates to restrict the relative rotation of the two adjacent regulating gate plates.

[0011] Furthermore, in this utility model, the aforementioned dividing frame is equipped with multiple support components from top to bottom, and the multiple support components are arranged in a corresponding manner with multiple adjusting gates; when the adjusting gate is flipped outward to the unloading position, the corresponding support component can abut against the flipped adjusting gate, thereby avoiding the unloading port.

[0012] Furthermore, in this utility model, the aforementioned support component includes: a support base with an assembly groove; a gate support shaft, at least partially disposed within the assembly groove, the gate support shaft slidingly guiding the assembly groove; and a second elastic member disposed within the assembly groove, one end of the second elastic member connected to the inner wall of the assembly groove, and the other end of the second elastic member connected to the gate support shaft; wherein the gate support shaft can abut against the outer wall of the adjusting gate after the adjusting gate is flipped outward, thereby avoiding the discharge port.

[0013] Furthermore, in this utility model, the aforementioned drive assembly includes: a connecting lug, which is installed at the bottom end of the cargo box body; and a hydraulic push rod, which is installed on the vehicle frame body, with the output end of the hydraulic push rod rotatably connected to the connecting lug.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. This application divides the main discharge port into multiple independent branch discharge ports using multiple partitioned frames. Each branch discharge port is equipped with a flow regulation component to form a zoned control mechanism. The flow regulation component achieves step-by-step control of the flow area by relying on the flipping action of the regulating gate, which can effectively curb the displacement of the discharge position and impact damage caused by the instantaneous surge of materials. It is particularly suitable for the fine unloading operation of highly fluid materials such as sand, gravel, and grain.

[0016] 2. This application employs a dual stability constraint system consisting of a locking pin and a gate linkage sleeve, and a support assembly and an abutting support for the regulating gate. The locking pin restricts the relative rotational freedom between adjacent regulating gates, while the support assembly provides rigid bottom support for the overturned regulating gate, eliminating the shaking and resetting phenomena caused by the regulating gate's own weight or material pressure. This ensures a long-term constant flow area in the discharge channel, making it particularly suitable for operational scenarios requiring quantitative batch unloading. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0026] Example

[0027] Please refer to Figure 1 and Figure 2 This utility model provides a side-tipping semi-trailer unloading structure. It includes a frame body 1, a cargo box body 2, multiple partition stands 7, multiple flow regulation components, and a drive component. The cargo box body 2 adopts a three-sided enclosed structure, with a main unloading port 5 formed along its length. One side of the bottom of the cargo box body 2 is rotatably connected to the frame body 1, while the other side can be supported on the frame body 1 to maintain a horizontal load-bearing state. Multiple partition stands 7 are spaced along the length of the main unloading port 5, forming secondary unloading ports 6 between adjacent partition stands 7. Each secondary unloading port 6 is equipped with a corresponding flow regulation component, which can adjust the flow area of ​​the secondary unloading port 6. The drive component is mounted on the frame body 1, and its output end is linked to the cargo box body 2, enabling the cargo box body 2 to achieve a side-tipping action around the rotatable connection.

[0028] During cargo transportation, multiple flow regulation components are in a closed state. By sealing the unloading port 6, the flow regulation components constrain the cargo within the cargo box body 2, ensuring load-bearing stability during transportation. After the vehicle arrives at the unloading site, the operator must first determine the physical characteristics of the cargo and then adjust the flow regulation components to set the target flow area of ​​the unloading port 6. For materials with high fluidity (such as sand, grains, powders, etc.), the control of the flow regulation components can avoid unloading risks caused by uncontrolled flow area: if the flow area of ​​such materials is too large in a horizontal state, it is easy to form a gushing discharge due to the instantaneous release of internal static pressure, which may cause the unloading trajectory to deviate from the preset area, and the high-speed impact of the material may cause damage to equipment or personnel, while increasing the difficulty of controlling quantitative unloading; by setting the flow regulation components to an appropriate flow area, the material can be discharged at a slow flow rate along a controlled path, which not only ensures unloading efficiency but also achieves control over the unloading process, meeting the needs of refined operations such as batch unloading.

[0029] For materials with poor flowability (such as lumpy materials, clay, and agglomerated materials), maintaining a stable flow area with the flow regulating component can effectively avoid unloading obstruction. If the flow regulating component does not form a fixed constraint, it is prone to shaking and resetting during unloading due to the gravity of the material or the torque change when the cargo box is tilted, causing frequent fluctuations in the flow area of ​​the unloading port 6 or even being squeezed and blocked by the material. In addition, the irregular state of the edge of the flow area may cause material to hook and accumulate, forming blockages and increasing the frequency of manual intervention. However, the structured control of the flow regulating component can ensure the stability and continuity of the flow path, ensuring a smooth unloading process. After the flow regulating component completes the preset flow area setting, the operator activates the drive component to drive the cargo box body 2 to perform a tilting action. With the tilted posture of the cargo box body 2 and the orderly flow guidance of the unloading port 6, the goods in the cargo box body 2 are discharged in a controlled manner along the preset path.

[0030] Multiple partition frames 7 are spaced apart along the extension direction of the main discharge port 5, with each pair of adjacent partition frames 7 forming an independent sub-discharge port 6. Each sub-discharge port 6 is equipped with a flow regulating component, which can dynamically control the flow area of ​​its respective sub-discharge port 6. During the unloading process, the material inside the cargo box 2 can be distributed to multiple sub-discharge ports 6 for simultaneous discharge, achieving distributed transmission of material load. This significantly reduces the material pressure borne by a single flow regulating component, thereby optimizing the stress state of the flow regulating component during regulation and improving the smoothness and operational accuracy of its regulation process.

[0031] Specifically, the chassis body 1 is equipped with multiple chassis crossbeams along its extension direction, and the cargo box body 2 is mounted on top of each chassis crossbeam in a load-bearing posture. One side of the bottom of the cargo box body 2 is hinged to one end of each of the multiple chassis crossbeams, and the other side of the bottom of the cargo box body 2 can rest on the other end of each of the multiple chassis crossbeams. In non-unloading conditions, the resting side of the cargo box body 2 forms a positioning fit with the corresponding end of each chassis crossbeam, thereby ensuring that the cargo box body 2 maintains a horizontal posture and structural stability during load-bearing and transportation.

[0032] Please refer to Figure 2 and Figure 3 In some embodiments of this application, the flow regulation component includes multiple regulating gates 8, each of which is arranged sequentially along the height direction of the unloading port 6. Adjacent regulating gates 8 are connected by a rotating structure. The uppermost regulating gate 8 is fixedly mounted between two adjacent partition frames 7 to form a supporting base, and the lowermost regulating gate 8 is detachably connected to the bottom of the cargo box body 2. When the lowermost regulating gate 8 is connected to the bottom of the cargo box body 2, it can work with the other regulating gates 8 to form a closed constraint on the unloading port 6, thereby confining the material within the cargo box body 2. During unloading operations, the operator first disconnects the lowermost regulating gate 8 from the bottom of the cargo box body 2, and then controls a preset number of regulating gates 8 to flip outward to the open position, so that the unloading port 6 forms a discharge channel with a corresponding preset flow area, thereby achieving precise control of the material discharge flow rate.

[0033] Specifically, the two sides of two adjacent regulating gates 8 can be hinged together by ear plates. The top and bottom ends of the regulating gates 8 are integrally formed with guide arc structures. The guide arc structures can effectively avoid motion interference between adjacent regulating gates 8 during relative rotation, so that adjacent regulating gates 8 can be arranged in close proximity. At the same time, elastic rubber strips are embedded between adjacent regulating gates 8. With the sealing and compensation effect of the elastic rubber strips, the fit gap between adjacent regulating gates 8 can be reduced, thereby preventing leakage of small materials during transportation.

[0034] Please refer to Figure 2 It should be noted that the connecting edge of the partition frame 7 and the regulating gate 8 is provided with an inwardly recessed mounting groove. When the regulating gate 8 is in the closed state, the edge of the regulating gate 8 can be fitted into the above-mentioned mounting groove. A sealing ring is circumferentially fitted on the outer periphery of the regulating gate 8. The limiting fit of the mounting groove and the elastic sealing effect of the sealing ring can significantly reduce the fit gap between the regulating gate 8 and the partition frame 7, thereby effectively preventing leakage of fine materials during transportation.

[0035] Please refer to Figure 2 and Figure 5In some embodiments of this application, a plurality of gate lock seats 12 are fixedly mounted on the bottom end of the cargo box body 2 along the extension direction, and each gate lock seat 12 is provided with a locking through hole 21; the outer wall of the lowest adjusting gate 8 is correspondingly fitted with a gate attachment 11, and the gate attachment 11 is provided with an installation groove 19. The installation groove 19 has a first elastic element 20 (reset spring) built in it. The free end of the first elastic element 20 is connected to a locking pin 13. The locking pin 13 can be engaged into the corresponding locking through hole 21 under the action of the elastic potential energy of the first elastic element 20, thereby forming a locking constraint on the adjusting gate 8. When the lowest adjusting gate 8 is connected to the bottom of the cargo box body 2, the operator presses the locking pin 13 to compress the first elastic element 20 until the locking pin 13 is completely retracted into the mounting groove 19. Then, the gate plate seat 11 is adjusted so that the mounting groove 19 and the locking through hole 21 are coaxially aligned. At this time, the locking pin 13 pops out and is embedded in the locking through hole 21 under the reset elastic force of the first elastic element 20, thus completing the locking and fixing of the lowest adjusting gate 8.

[0036] It should be noted that when multiple regulating gates 8 are in the closed state, they can collectively form a closed structure for the discharge port 6. At this time, a locking constraint is applied to each regulating gate 8 to restrict its rotational freedom. When the lowest regulating gate 8 is locked, the remaining regulating gates 8 in the same flow regulating assembly are all linked and cannot rotate relative to each other. This constraint mechanism effectively prevents the locking pin 13 from disengaging from the locking through hole 21, thus ensuring the reliability of the locking structure. On the other hand, considering the rationality of the structural design and ease of operation, using a method where the locking pin 13 passes through the locking through hole 21 and is then locked a second time with a nut is actually an alternative supplementary fixing scheme. The nut locking method is more of an auxiliary means to deal with special working conditions and is not the optimal design choice.

[0037] Please refer to Figure 2 In some embodiments of this application, at least one gate linkage sleeve 9 is fixedly mounted on each regulating gate 8, and the gate linkage sleeves 9 of two adjacent regulating gates 8 can be coaxially aligned in corresponding postures; the linkage locking pin 10 can be inserted into the gate linkage sleeves 9 of two adjacent regulating gates 8 to constrain the relative rotation of the two adjacent regulating gates 8. When the discharge port 6 is closed, the multiple regulating gates 8 cooperate to form a closed state, and the gate linkage sleeves 9 of two adjacent regulating gates 8 are coaxially aligned. The linkage locking pin 10 is sequentially inserted into the corresponding gate linkage sleeves 9 of the two adjacent regulating gates 8 to complete the locking, which can restrict the relative rotation of the two adjacent regulating gates 8.

[0038] When the operator needs to open the discharge channel with a preset flow area, first flip the preset number of regulating gates 8 outward to the set angle so that the discharge port 6 forms a discharge channel with the corresponding flow area. All the outwardly flipped regulating gates 8 need to be locked in the flipped position to resist gravity and prevent them from falling. Then, the linkage locking pin 10 is inserted into the gate linkage sleeve 9 of the two adjacent flipped regulating gates 8. The rigid cooperation between the linkage locking pin 10 and the linkage sleeve forms a continuous constraint, so that all the outwardly flipped regulating gates 8 form an overall stable structure by locking each other, thereby maintaining the current flipped posture under the action of gravity and ensuring the constancy of the discharge channel.

[0039] In some embodiments of this application, the partition frame 7 is equipped with multiple support components 14 from top to bottom, and each support component 14 is arranged in a one-to-one correspondence with the regulating gate 8. When the regulating gate 8 is flipped outward to the unloading operation position, the corresponding support component 14 can form a rigid abutment with the flipped regulating gate 8 to avoid the unloading port 6. When it is necessary to open the discharge channel with a preset flow area, a preset number of regulating gates 8 are first flipped outward to a set angle. After the preset number of regulating gates 8 have completed the outward flipping action, the support component 14 at the corresponding position can form an integral support for all the outwardly flipped regulating gates 8. The support component 14 at the corresponding position is the support component 14 that matches the regulating gate 8 that is closest to the top and flipped outward.

[0040] Please refer to Figure 4 Specifically, the support assembly 14 consists of a support base 15, a gate support shaft 18, and a second elastic element 17 (reset spring). The support base 15 has an assembly groove 16, and the gate support shaft 18 is at least partially embedded in the assembly groove 16 and forms a sliding guide engagement with it. The second elastic element 17 is built into the assembly groove 16, with one end of the second elastic element 17 fixed to the inner wall of the assembly groove 16 and the other end connected to the gate support shaft 18. During operation, the operator first flips a preset number of regulating gates 8, and then pushes the gate support shaft 18 into the assembly groove 16 to avoid interfering with the flipping action of the regulating gates 8, thereby causing the second elastic element 17 to undergo compression deformation. When the regulating gates 8 are flipped to the set position, the gate support shaft 18 moves to the bottom of the regulating gates 8 under the action of the reset spring force of the second elastic element 17, thereby providing support for the regulating gates 8.

[0041] It should be noted that, from the perspective of operational feasibility and structural design adaptability, the number of regulating gates 8 can be set to three. This configuration can form a reasonable distribution of operational load in actual operation. Specifically, when adjusting the discharge channel, a maximum of two regulating gates 8 need to be flipped outward to achieve the preset flow area. During this process, since each regulating gate 8 corresponds to a gate support shaft 18, the operator only needs to apply a pushing force to the two gate support shafts 18 corresponding to the two flipped regulating gates 8 to avoid mechanical interference from the gate support shafts 18 on the flipping action of the regulating gates 8. A single operator can independently complete the entire operation, fully demonstrating the design advantages of this structure in terms of operational convenience and labor cost control.

[0042] In some embodiments of this application, the connecting lug 4 is mounted on the bottom end of the cargo box body 2, and the hydraulic push rod 3 is mounted on the frame body 1. The output end of the hydraulic push rod 3 is rotatably connected to the connecting lug 4. From a structural layout perspective, the hydraulic push rod 3 is installed at an angle, which effectively adapts to the tilting requirements of the cargo box body 2 and provides support for tilting the cargo box body 2 to a greater angle. The hydraulic push rod 3 and the connecting lug 4 can be connected by a hinge or a universal joint. The relative angular offset between the hydraulic push rod 3 and the connecting lug 4 during the tilting process of the cargo box body 2 is effectively compensated, avoiding additional stress caused by restricted relative movement.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
