Description

Technical Field

[0001] This invention relates to the field of dump truck technology, and in particular to a highly adaptable dump truck body structure. Background Technology

[0002] Ordinary dump trucks currently mainly use hydraulic tipping for unloading. Because these trucks require lifting the cargo box during unloading, they have high space requirements and cannot operate normally in low, confined spaces such as tunnels, mines, and indoors. Furthermore, the tipping unloading method generates a large impact, which not only easily causes material to spill and fly, resulting in waste, but also poses safety hazards. Improper operation can easily cause the dump truck to tip over, leading to accidents.

[0003] Currently, belt-driven dump trucks are beginning to appear on the market. These trucks use a conveyor belt to continuously output materials from the rear of the truck bed, eliminating the need to lift the truck bed during unloading. They can operate in any low-ceilinged space, making them highly adaptable. The materials are transported smoothly without spillage or splashing, ensuring safety and environmental friendliness while significantly improving safety.

[0004] However, existing belt-driven dump truck bodies mostly use fixed sliding plates or fixed rollers for support at the bottom, resulting in a simple structure and a lack of adaptability. Under heavy load conditions, the normal pressure between the belt and the bottom support surface increases, leading to a significant increase in frictional resistance. This not only accelerates belt wear and shortens its service life but also increases the energy consumption of the drive system. Furthermore, fixed supports cannot adjust their shape according to changes in load, making it difficult to compensate for belt deflection variations under different loads. This can easily cause belt misalignment or localized stress concentration, affecting transportation stability.

[0005] Therefore, the structure of the dump truck body needs further improvement to adapt to the needs of different loading environments. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a highly adaptable dump truck body structure to solve the problems of existing ordinary dump trucks being unable to adapt to narrow environments and lacking safety when unloading.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a highly adaptable dump truck body structure, comprising:

[0008] The main body of the vehicle frame includes beams and a box body. The beams include a pair of main beams, crossbeams, and supporting beams. The main beams are distributed along a first direction, and the crossbeams are distributed along a second direction and spaced apart between the main beams. The highest point of the supporting beam is higher than the highest point of the crossbeam. The crossbeam and its adjacent supporting beam form an installation cavity. The installation cavities are arranged in an array. The box body is located above the vehicle frame and includes a floor plate and side walls set on the floor plate. The floor plate is connected to the supporting beams and the main beams. The floor plate has a push-pull channel corresponding to the installation cavity.

[0009] The pushing module is set in the installation cavity and extends from the installation cavity into the pushing channel. The pushing module includes a lifting component and a support roller assembly. The support roller assembly is set at the output end of the lifting component, and the lifting component is fixed to the top of the crossbeam.

[0010] The conveying module, located above the base plate, includes a conveyor belt assembly and a pusher plate assembly. The conveyor belt assembly is located above the base plate, and the pusher plate assembly is located on the side away from the drive end of the conveyor belt assembly. When the conveyor belt assembly is in operation, the conveyor belt assembly drives the pusher plate assembly to move towards the drive end of the conveyor belt assembly. When the pusher plate assembly is in operation, the pusher plate assembly drives the conveyor belt assembly to reset.

[0011] The lifting assembly drives the support roller group to rise and fall, so that part of the support roller group extends above the base plate, thereby causing the support roller group to push against the conveyor belt group in different areas.

[0012] In one embodiment, the support roller assembly includes a support seat, a rotating lug seat, and a rotating roller. The rotating lug seats are vertically distributed and disposed on both sides of the support seat in a second direction. The rotating roller is rotatably connected to the rotating lug seats. In the vertical projection, the projected area of ​​the support seat is larger than the projected area of ​​the mounting cavity. Under the action of the lifting assembly, the support seat moves closer to or further away from the top of the support beam.

[0013] In one embodiment, the bottom of the push channel is provided with a receiving ring cavity corresponding to the bearing seat, and the bearing seat abuts against the inner wall of the receiving ring cavity.

[0014] In one embodiment, the support roller assembly further includes a blower pipe, which is disposed on both sides of the support seat in a first direction. The blower pipe is distributed along the second direction above the crossbeam. After entering the lower part of the support seat, the blower pipe extends through the nearest mounting through hole on the support seat to the upper part of the support seat, and extends along the upper surface of the support seat before returning to the lower part of the support seat through the mounting through hole at the other end. The inner wall of the receiving annular cavity is provided with a blower channel, which allows the receiving annular cavity to communicate with the outside from the lower part of the bottom plate.

[0015] In one embodiment, the top of the push channel has a recessed inclined wall that extends from the inner wall of the push channel toward the center of the push channel, and the wall thickness of the recessed inclined wall gradually decreases from the outer edge of the push channel to the center of the push channel; after the rotating roller rises, at least a portion of the rotating roller extends out from the recessed inclined wall.

[0016] In one embodiment, the lifting assembly includes a hydraulic lifting cylinder and a pressure sensor. The fixed end of the hydraulic lifting cylinder is located on the top of the crossbeam, and the output end of the hydraulic lifting cylinder is connected to the support seat through the pressure sensor. The pressure sensor is used to detect the pressure transmitted from the support seat to the hydraulic lifting cylinder.

[0017] In one embodiment, the conveyor belt assembly includes a drive roller and a conveyor belt. The drive roller is disposed between the main beams, and one end of the conveyor belt is connected to the drive roller. The push plate assembly and the drive roller are respectively located on both sides of the main beam. The push plate assembly includes a drive hinge, a sliding frame, and a material push plate. The top of the material push plate is rotatably connected to the sliding frame, and the other end of the conveyor belt is connected to the bottom of the sliding frame. The drive hinge is fixed to the side wall at the end of the box, and the sliding frame is connected to the movable end of the drive hinge.

[0018] In one embodiment, the sliding frame is L-shaped, and the middle part of the sliding frame is connected to the middle part of the material push plate through a telescopic bracket.

[0019] In one embodiment, sliding rails are provided on the side walls on both sides of the second direction of the compartment, and sliders are provided on the sliding frame corresponding to the sliding rails, with the sliders embedded in the sliding rails.

[0020] In one embodiment, a cleaning channel is provided on the side of the base plate near the push plate assembly, and a rotatable movable scraper is provided at the bottom of the push plate assembly. The movable scraper abuts against the upper surface of the base plate when the push plate assembly is in operation.

[0021] The beneficial effects of this invention are as follows:

[0022] Conventional dump trucks require lifting the cargo box during unloading, which demands ample space and makes them unsuitable for complex working environments. They also pose a safety hazard due to tipping. Existing belt-driven dump trucks typically use fixed sliding plates or rollers for support, resulting in a simplistic and unreliable structure. Under heavy loads, the high friction between the belt and the support surface exacerbates wear, leading to high operating costs and frequent breakdowns.

[0023] The highly adaptable dump truck structure provided by this invention employs an array of mounting cavities formed by crossbeams and supporting beams with height differences. This allows for the installation of lifting and lowering support rollers within each cavity without affecting the stress transmission of the chassis. The lifting and lowering of these support rollers creates an array of protrusions at the bottom of the conveyor belt assembly. These protrusions support and push different areas of the conveyor belt assembly, introducing gaps in the contact between the conveyor belt assembly and the entire plane of the base plate. This reduces the contact area within the conveyor belt's deflection range, thus lowering friction. Furthermore, the support rollers convert sliding friction into rolling friction, significantly reducing friction and further decreasing the resistance and wear of the conveyor belt assembly during operation. The pushing module can employ different protrusion heights and distributions under different load conditions to adapt to varying operational requirements. During transport, the support rollers can lower, reducing excessive pushing of the protrusions against the conveyor belt, preventing localized deformation of the conveyor belt, and further extending the belt's service life.

[0024] Meanwhile, the conveyor belt assembly and push plate assembly of the highly adaptable self-unloading truck body structure provided by the present invention adopt a two-way linkage structure. The operation of the conveyor belt assembly drives the push plate assembly to assist in unloading, and the reset of the push plate assembly drives the conveyor belt to return to its position. This ensures that the conveying module as a whole is kept taut while improving the overall rigidity of the structure and avoiding [further issues].

[0025] Other features and beneficial effects of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects of the invention and other beneficial effects may be realized and obtained by means of the structures and / or components pointed out in the description and claims.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. The technical features designed in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be noted that all terms used in this invention (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains, and should not be construed as limiting the invention; it should be further understood that the terms used in this invention should be understood to have the same meaning as those in the context of this specification and in the relevant field, and should not be understood in an idealized or overly formal sense, except as expressly defined in this invention.

[0038] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0039] Please refer to Figures 1 to 7 A highly adaptable dump truck body structure, comprising:

[0040] The main frame 1 includes a beam 11 and a box 12. The beam 11 includes a pair of main beams 111, a crossbeam 112, and a supporting beam 113. The main beams 111 are distributed along a first direction, and the crossbeams 112 are distributed along a second direction and spaced apart between the main beams 111. The highest point of the supporting beam 113 is higher than the highest point of the crossbeam 112. A mounting cavity 114 is formed between the crossbeam 112 and its adjacent supporting beam 113. The mounting cavities 114 are arranged in an array. The box 12 is located above the frame and includes a bottom plate 121 and side walls on the bottom plate 121. The bottom plate 121 is connected to the supporting beams 113 and the main beams 111. The bottom plate 121 has a push-pull channel 122 corresponding to the mounting cavity 114.

[0041] The push module 2 is set in the mounting cavity 114 and extends from the mounting cavity 114 to the push channel 122. The push module 2 includes a lifting component 21 and a support roller group 22. The support roller group 22 is set at the output end of the lifting component 21. The lifting component 21 is fixed to the top of the crossbeam 112.

[0042] The conveying module 3 is located above the base plate 121 and includes a conveyor belt assembly 31 and a pusher plate assembly 32. The conveyor belt assembly 31 is located above the base plate 121, and the pusher plate assembly 32 is located on the side away from the drive end of the conveyor belt assembly 31. When the conveyor belt assembly 31 is in operation, the conveyor belt assembly 31 drives the pusher plate assembly 32 to move towards the drive end of the conveyor belt assembly 31. When the pusher plate assembly 32 is in operation, the pusher plate assembly 32 drives the conveyor belt assembly 31 to reset.

[0043] The lifting assembly 21 drives the support roller group 22 to rise and fall, so that part of the support roller group 22 extends above the base plate 121, thereby causing the support roller group 22 to push the conveyor belt group 31 in different areas.

[0044] Specifically, the crossbeam 112 can be positioned above the main beam 111, thus not affecting the installation of other structures of the dump truck. Specifically, the wheels, support structures, hydraulic doors, pneumatic systems, drive systems, and hydraulic systems mounted on the main frame 1 can be selected and adjusted by those skilled in the art according to actual needs, without specific limitations.

[0045] In this embodiment, the support roller assembly 22 includes a support seat 221, a rotating lug seat 222, and a rotating roller 223. The rotating lug seat 222 is vertically distributed and disposed on both sides of the support seat 221 in the second direction. The rotating roller 223 is rotatably connected to the rotating lug seat 222. In the vertical projection, the projected area of ​​the support seat 221 is larger than the projected area of ​​the mounting cavity 114. Under the action of the lifting assembly 21, the support seat 221 moves closer to or further away from the top of the receiving beam 113. That is, the area of ​​the support seat 221 is larger than the area of ​​the top of the mounting cavity 114, so that when the support seat 221 is at its lowest point, it abuts against the top of the receiving beam 113, forming a mechanical limit. This not only prevents the support roller assembly 22 from falling off and enhances the overall rigidity, but also shields the mounting cavity 114 and the lifting assembly 21, preventing materials from falling into the mounting cavity 114 during the operation of the conveyor belt assembly 31, reducing the interference of materials on the lifting assembly 21, and ensuring the stability of the operating environment of the lifting assembly 21.

[0046] Since the base plate 121 is positioned above the supporting beam 113, to avoid interference between the bearing seat 221 and the pushing channel 122, in this embodiment, a receiving annular cavity 123 is provided at the bottom of the pushing channel 122 corresponding to the bearing seat 221, and the bearing seat 221 abuts against the inner wall of the receiving annular cavity 123. The receiving annular cavity 123 provides lifting space for the bearing seat 221, ensuring that its lifting is not interfered with. Simultaneously, the receiving annular cavity 123 provides an upward limit for the bearing seat 221, preventing it from extending too far and causing excessive deformation of the conveyor belt 312 or interference with other structures, thereby improving the operational stability of the conveying module 3.

[0047] After the receiving annular cavity 123 is set up, the material falling from the push channel 122 will accumulate above the support seat 221. During long-term operation, excessive accumulation of material will affect the lifting space of the support seat 221, or local accumulation will cause uneven force on the support seat 221, seriously affecting the normal operation of the support roller group 22. Therefore, in this embodiment, the support roller group 22 also includes a blow pipe 224. The blow pipe 224 is set on both sides of the support seat 221 in the first direction. The blow pipe 224 is distributed along the second direction above the crossbeam 112. After entering the lower part of the support seat 221, the blow pipe 224 extends to the upper part of the support seat 221 through the nearest mounting through hole on the support seat 221, and extends along the upper surface of the support seat 221 before returning to the lower part of the support seat 221 through the mounting through hole at the other end. The inner wall of the receiving annular cavity 123 is provided with a blow channel 126, which allows the receiving annular cavity 123 to communicate with the outside from the lower part of the bottom plate 121. The purge pipe 224 is arranged in a bottom-up-bottom direction. It passes through the two mounting holes of the support seat 221, allowing the purge part to adhere to the upper surface of the support seat 221. Then, compressed air is used to purge the material accumulated on the surface of the annular cavity 123 and the support seat 221. The purge airflow carrying the material is sprayed from the purge channel 126 to the hollow part of the beam 11, thereby ensuring that the support roller group 22 is not affected by the material after long-term use and effectively improving the stability of the push module 2.

[0048] Specifically, the purge pipe 224 is connected to an external air supply device. Those skilled in the art can use equipment such as an air compressor to supply air, without making specific limitations.

[0049] When the support roller group 22 is not unloading, its highest point is flush with the upper surface of the base plate 121. However, after the push channel 122 is set, the unloaded material forms several depressions on the surface of the base plate 121. The conveyor belt 312 corresponding to these depressions only touches the support roller group 22 in the middle, while the rest is suspended. Under heavy load, this can cause local deformation of the conveyor belt 312, and long-term use will also affect the service life of the conveyor belt 312. Therefore, in this embodiment, the top of the push channel 122 has a recessed inclined wall 124. The recessed inclined wall 124 extends from the inner wall of the push channel 122 to the center of the push channel 122, and the wall thickness of the recessed inclined wall 124 gradually decreases from the outer edge of the push channel 122 to the center of the push channel 122. After the rotating roller 223 rises, at least a portion of the rotating roller 223 extends out from the recessed inclined wall 124. With the recessed inclined wall 124 installed, it can support the downward-pressing conveyor belt 312, reducing its deformation. Simultaneously, during conveyor belt 312 operation, the recessed inclined wall 124 and the rotating roller 223 form a structure that is initially low, then high, and then low again. This not only better creates an air gap to adapt to different load conditions, but the inclined surface also guides the forward movement of the conveyor belt 312, preventing the edges of the pushing channel 122 from scratching it, thereby increasing the service life of the conveyor belt 312 and reducing operating costs.

[0050] In this embodiment, the lifting assembly 21 includes a hydraulic lifting cylinder and a pressure sensor. The fixed end of the hydraulic lifting cylinder is located on the top of the crossbeam 112, and the output end of the hydraulic lifting cylinder is connected to the support seat 221 through the pressure sensor. The pressure sensor is used to detect the pressure transmitted from the support seat 221 to the hydraulic lifting cylinder. The pressure sensor allows operators to make targeted adjustments to different areas, preventing the lifting assembly 21 from rising too high and damaging the conveyor belt 312, thus improving overall stability and service life. Furthermore, the pressure sensor allows for the determination of the distribution of large hard objects in the material based on the lifting height and pressure of the hydraulic lifting cylinder, thereby adjusting the lifting height of the hydraulic lifting cylinder in real time and preventing the support roller assembly 22 from rising too high and being damaged by large hard objects.

[0051] Preferably, the hydraulic lifting cylinder is controlled individually, so that the pushing module 2 can form an array of protrusions with different height differences in different areas, further improving the overall adjustability of the structure, reducing the friction under different load conditions, and thus improving adaptability.

[0052] In this embodiment, the conveyor belt assembly 31 includes a drive roller 311 and a conveyor belt 312. The drive roller 311 is disposed between the main beams 111, and one end of the conveyor belt 312 is connected to the drive roller 311. The push plate assembly 32 and the drive roller 311 are respectively located on both sides of the main beam 111. The push plate assembly 32 includes a drive hinge 321, a sliding frame 322, and a material push plate 323. The top of the material push plate 323 is rotatably connected to the sliding frame 322, and the other end of the conveyor belt 312 is connected to the bottom of the sliding frame 322. The drive hinge 321 is fixed to the side wall at the end of the box 12, and the sliding frame 322 is connected to the movable end of the drive hinge 321. Specifically, the overall structure of the sliding frame 322 corresponds to that of the box 12, and the bottom of the sliding frame 322 is slidably connected to the bottom plate 121. The bottom of the sliding frame 322 has an avoidance notch corresponding to the support roller assembly 22 to prevent the support roller assembly 22 from being collided with.

[0053] Specifically, the two ends of the drive roller 311 are connected to the main beam 111 or the box body 12, and the drive roller 311 is hydraulically driven.

[0054] Specifically, the art can arbitrarily set a suitable sliding frame 322 as needed, without making specific limitations.

[0055] In this embodiment, the sliding frame 322 is generally L-shaped, and the middle part of the sliding frame 322 is connected to the middle part of the material push plate 323 through the telescopic bracket 324. Preferably, the telescopic bracket 324 is provided with a buffer spring. This arrangement allows the material push plate 323 to rotate to a certain extent during loading or pushing, thereby buffering the force and preventing the material push plate 323 from being damaged due to excessive force.

[0056] In this embodiment, sliding rails 125 are provided on the side walls of the two sides of the body 12 in the second direction, and sliders are provided on the sliding frame 322 corresponding to the sliding rails 125, with the sliders embedded in the sliding rails 125. This arrangement can limit the sliding frame 322 and prevent it from tipping over under the tension at both ends, thereby improving the overall stability of the conveying module 3.

[0057] In this embodiment, a cleaning channel is provided on the side of the base plate 121 near the push plate assembly 32, and a rotatable movable scraper is provided at the bottom of the push plate assembly 32. The movable scraper abuts against the upper surface of the base plate 121 when the push plate assembly 32 is in operation.

[0058] Preferably, the movable scraper is rotatably connected to the sliding frame 322 by a coil spring, so that the movable scraper can rotate upward when the pusher assembly 32 pushes outward, thereby avoiding interference between the movable scraper and the support roller group 22.

[0059] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of the present invention can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or the background art simultaneously. Those skilled in the art should understand that any content not mentioned in a claim should not be construed as a limitation on that claim.

[0060] Although this document frequently uses terms such as frame body, beam, and main beam, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any kind of additional limitation would contradict the spirit of the invention. The terms "first," "second," etc. (if present) in the specification and claims of the embodiments of the invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
