Description

Technical Field

[0001] This utility model belongs to the field of anti-sticking technology for off-highway dump truck cargo boxes, and particularly relates to an anti-sticking device for cargo boxes, an off-highway dump truck cargo box, and an off-highway dump truck. Background Technology

[0002] Off-highway dump trucks are transportation equipment used in open-pit coal mines, cement and building materials mines, sand and gravel aggregate mines, metal and non-metal mines, water conservancy and hydropower projects, and large-scale engineering projects. The cargo box is the working device of the vehicle, mainly used for loading, transporting, and unloading mining materials.

[0003] When the cargo box is loaded with highly adhesive materials such as clay and wet materials, they tend to stick to the front panel and corners of the cargo box. Especially in winter, the material stuck to the corners will freeze. As the number of trips increases, the amount of material stuck to the corners will increase, resulting in a decrease in the load capacity, an increase in the energy consumption of the vehicle, a serious impact on the operating efficiency, and economic losses.

[0004] In existing technologies, fuel-powered vehicles typically use exhaust from their internal combustion engines to heat the inner surface of their cargo boxes. The exhaust can be guided through the cargo box structure to heat the inner surface, thus facilitating material discharge during unloading. However, with the policy orientation towards green mining and intelligentization, fuel-powered vehicles are being replaced by electric vehicles. Therefore, the method of heating the cargo box and releasing sticky materials via internal combustion engine exhaust is no longer applicable. Summary of the Invention

[0005] One object of the present invention is to solve at least the above-mentioned problems and / or defects, and to provide at least the advantages described below.

[0006] Another objective of this utility model is to provide a cargo box anti-sticking device, a cargo box for off-highway dump trucks, and an off-highway dump truck.

[0007] This addresses the issue of non-highway dump trucks where sticky materials tend to adhere to the inner walls of the front and side panels of the cargo box, leading to incomplete unloading and the need for manual cleaning of residual materials. Specifically, this manifests as material accumulating in the corners of the cargo box, forming hard lumps, which affects unloading efficiency and vehicle load balance, increasing operating costs and maintenance time.

[0008] The problem of significant frictional resistance between the counterweight and the bottom of the cargo box during the rotation of the anti-stick plate, which leads to inflexible rotation or even jamming, is addressed. This affects the timely reset of the anti-stick plate and the material release effect, reducing the reliability of the device.

[0009] Therefore, the technical solution provided by this utility model is as follows: A cargo box anti-sticking device, comprising: The system includes: an anti-stick plate, the shape of which is adapted to fit the inner contour of the front and side panels of the cargo box; a fastener, which is fixedly connected to the front panel of the cargo box; a pin, with matching through holes on the fastener and the connector for the pin to pass through; a connector, one end of which is hinged to the fastener via the pin, and the other end of which is fixedly connected to the anti-stick plate; a counterweight, located at the lower part of the anti-stick plate and in front of it, used to drive the anti-stick plate to rotate around the pin under the action of gravity during unloading; and a support plate, located between the anti-stick plate and the front panel of the cargo box, with its bottom fixedly connected to the bottom panel of the cargo box, and the plane of the support plate intersecting the plane of the front panel of the cargo box to form an angle between the anti-stick plate and the front panel of the cargo box.

[0010] Preferably, the cargo box anti-sticking device further includes a roller shaft, which is rotatably connected to the counterweight and located below the anti-sticking plate.

[0011] Preferably, the cargo box anti-sticking device includes a hydraulic cylinder, the cylinder body of which is fixedly connected to the front plate of the cargo box, and the piston rod end of which is connected to the anti-sticking plate.

[0012] Preferably, in the cargo box anti-sticking device, the shape of the anti-sticking plate is configured to adapt to the inner contour of the front panel and side panel of the cargo box, including the anti-sticking plate being recessed towards the side closer to the front panel of the cargo box, and the anti-sticking plate having transition edges on both sides for contacting the side panel of the cargo box.

[0013] Preferably, in the cargo box anti-sticking device, the support plate has weight-reducing holes, and at the corner where the support plate connects to the front plate and bottom plate of the cargo box, part of the material is removed to form a weight-reducing structure.

[0014] Preferably, in the cargo box anti-sticking device, the support plate faces the back of the anti-sticking plate, and the side of the support plate that contacts the anti-sticking plate matches the position of the anti-sticking plate in its reset state.

[0015] Preferably, the plane where the support plate is located intersects with the plane where the front panel of the cargo box is located includes: the support plate being perpendicular to the front panel of the cargo box.

[0016] A cargo box for an off-highway dump truck includes a front panel, side panels, and a bottom panel, wherein at least one set of anti-sticking devices is provided inside the cargo box.

[0017] An off-highway dump truck includes a cargo box anti-sticking device or an off-highway dump truck cargo box.

[0018] The embodiments of this utility model include at least the following beneficial effects: This utility model adapts the anti-stick plate to the inner contour of the front and side panels of the cargo box. Combined with the synergistic effect of the fixing parts, pins, connecting parts, counterweights and support plates, the anti-stick plate automatically rotates under the action of gravity during unloading, effectively preventing material adhesion, improving the thoroughness of unloading, reducing the need for manual cleaning, and enhancing the stability and applicability of the device, while reducing maintenance costs.

[0019] This invention adds a roller shaft that can be rotatably connected to the counterweight and is located below the anti-stick plate. This reduces the frictional resistance between the counterweight and the bottom of the cargo box, making the anti-stick plate rotate more flexibly and smoothly, improving the response speed and reliability of the device, avoiding jamming, and extending the service life of the components.

[0020] This invention uses a hydraulic cylinder whose body is fixed to the front panel of the cargo box, with the piston rod end connected to the anti-stick plate. This allows for precise control of the anti-stick plate's rotation angle, enhancing operational stability and automation, adapting to different working conditions, and improving anti-sticking effect and unloading efficiency. When the counterweight cannot drive the anti-stick plate to rotate around the pin shaft under gravity, the hydraulic cylinder can control the anti-stick plate's rotation by extending and retracting the piston rod, thus ensuring that the material adhering to the cargo box is pushed out.

[0021] This utility model uses an anti-stick plate that is recessed into the front panel of the cargo box to form a transition edge, ensuring close contact with the side panel of the cargo box, eliminating dead corners in the anti-sticking process, fully covering the inner wall of the cargo box, preventing material residue, and improving the uniformity of anti-sticking and the overall unloading quality.

[0022] This utility model reduces the weight of the support plate by creating weight-reducing holes on the support plate and removing material at the corners to form a weight-reducing structure. This reduces the overall load on the cargo box, improves the vehicle's load-bearing performance and fuel economy, and facilitates installation and maintenance, thus enhancing the structural rationality.

[0023] This invention ensures a tight fit between the support plate and the anti-stick plate by matching the back of the support plate with the contact side of the anti-stick plate in the reset state, thereby enhancing the stability of the anti-stick plate, preventing shaking and displacement, and improving the durability of the device and the consistency of the anti-stick effect.

[0024] This utility model integrates the overall anti-stick function of the cargo box by setting at least one set of anti-stick devices inside the cargo box, which simplifies the structural design, reduces manufacturing costs, improves installation convenience and maintenance efficiency, and is applicable to various types of cargo boxes.

[0025] This utility model enhances the adaptability and compatibility of off-highway dump trucks under harsh working conditions by including an anti-sticking device in the cargo box or an off-highway dump truck cargo box, expands the application scope, improves unloading efficiency and operating economy, and promotes technology dissemination.

[0026] Other advantages, objectives, and features of the embodiments of this utility model will be apparent in part from the following description, and in part will be understood by those skilled in the art through study and practice of the embodiments of this utility model.

[0032] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement them based on the description.

[0033] This utility model proposes a cargo box anti-sticking device 2, such as Figures 1 to 4 As shown, it includes: Anti-stick plate 205, the shape of which is adapted to fit the inner contour of the front panel 1 and the side panel 3 of the cargo box; Fastener 201 is fixedly connected to the front panel 1 of the cargo box; The pin 202 has matching through holes on the fixing member 201 and the connecting member 204 for the pin 202 to pass through. Connector 204, one end of which is hinged to the fixing member 201 via the pin 202, and the other end is fixedly connected to the anti-stick plate 205; The counterweight 206 is disposed at the lower part of the anti-stick plate 205 and located in front of the anti-stick plate 205. It is used to drive the anti-stick plate 205 to rotate around the pin 202 under the action of gravity during unloading. Support plate 203 is located between the anti-stick plate 205 and the front panel 1 of the cargo box. The bottom of the support plate 203 is fixedly connected to the bottom plate 4 of the cargo box. The plane of the support plate 203 intersects the plane of the front panel 1 of the cargo box, so as to form an angle between the anti-stick plate 205 and the front panel 1 of the cargo box. The angle is preferably 90°.

[0034] One feasible implementation is as follows: The anti-stick plate 205 is made of high-strength steel plate, and its shape precisely matches the inner contour of the junction of the front panel 1 and the side panel 3 of the cargo box. The fastener 201 is firmly connected to the inner surface of the front panel 1 of the cargo box by welding. One end of the connector 204 is fixedly connected to the upper middle part of the anti-stick plate 205 by welding. Through holes are respectively opened at corresponding positions of the fastener 201 and the connector 204, and the pin 202 passes through these through holes to form a hinge connection, so that the anti-stick plate 205 can rotate around the axis of the pin 202. A counterweight 206 is fixedly installed at the lower front position of the anti-stick plate 205. The counterweight 206 is made of cast iron. A support plate 203 is also provided. The support plate 203 is inclinedly arranged between the anti-stick plate 205 and the front panel 1 of the cargo box. The bottom of the support plate 203 is fixedly connected to the bottom plate 4 of the cargo box, and the plane of the support plate 203 intersects the plane of the front panel 1 of the cargo box.

[0035] Current technologies typically involve lining the inner walls of the cargo container with fixed plastic or metal plates, or relying on manual tapping to remove adhering materials. These methods cannot be automated during unloading, have limited anti-sticking effectiveness, and are reliance on manual labor. During unloading, the materials rely entirely on their own weight to detach. For highly adhesive materials such as wet soil and mineral powder, a significant amount will still adhere to the lining surface, requiring manual cleaning after unloading, increasing operating time and labor costs.

[0036] This invention, through the adaptive design of the anti-stick plate 205 to the inner contour of the cargo box, combined with the hinge mechanism and counterweight 206, utilizes the combined effect of the material's gravity and the counterweight 206 during unloading to cause the anti-stick plate 205 to rotate automatically, effectively breaking the adhesion between the material and the cargo box wall. The support plate 203 ensures a stable angle between the anti-stick plate 205 and the front panel 1 of the cargo box, which neither hinders the loading process nor hinders the material's sliding during unloading. The entire device has a reasonable structure, requires no external power, achieves automatic anti-stick function, significantly improves unloading efficiency and thoroughness, and reduces the need for manual cleaning.

[0037] According to one preferred embodiment of this utility model, the anti-stick device for the cargo box further includes: Roller 207 is rotatably connected to the counterweight 206 and located below the anti-stick plate 205.

[0038] One feasible implementation involves installing a roller 207 on the counterweight 206. This roller 207 is rotatably connected to the lower part of the counterweight 206 via bearings or bushings, and positioned below the anti-stick plate 205. When the anti-stick plate 205 needs to rotate under the influence of the counterweight 206, the roller 207 will contact the cargo box floor 4 before the counterweight 206 itself. Through the rolling motion of the roller 207, the original sliding friction between the counterweight 206 and the cargo box floor 4 is transformed into rolling friction.

[0039] The existing technology uses only a simple counterweight of 206 pieces. This counterweight 206 pieces directly contact the cargo box floor 4. During the initial rotation and reset process, due to the large contact surface and sliding friction, significant resistance is generated. This resistance is even greater when there is material residue or unevenness on the cargo box floor 4, which may cause the anti-stick plate 205 to move slowly, not rotate completely, or even get completely stuck, losing its anti-stick function.

[0040] This invention significantly reduces frictional resistance during rotation by adding a rotatable roller 207. This makes the rotation of the anti-stick plate 205 more sensitive and smooth, ensuring the reliability of the device's operation. The anti-stick plate 205 can easily reach the intended position, effectively breaking up material adhesion, while reducing wear between components and extending the overall service life of the device.

[0041] According to one embodiment of the present invention, as a preferred embodiment, the cargo box anti-sticking device includes a hydraulic cylinder, the cylinder body of which is fixedly connected to the front plate 1 of the cargo box, and the piston rod end of which is connected to the anti-sticking plate 205.

[0042] One feasible implementation involves adding a hydraulic cylinder as a drive and control component. The cylinder body is securely fixed to the inside of the front panel 1 of the cargo box via a bracket or base. The end of the piston rod of the hydraulic cylinder is connected to the surface of the anti-stick plate 205 via another hinge point. The extension and retraction of the piston rod of the hydraulic cylinder are controlled by an external hydraulic system, thereby actively and precisely controlling the rotation angle and speed of the anti-stick plate 205.

[0043] This invention utilizes a hydraulic cylinder drive to achieve active and precise control over the rotation of the anti-stick plate 205. Regardless of the material properties, it ensures that the anti-stick plate 205 reliably operates at the set angle and timing, greatly improving the stability and consistency of the anti-sticking effect. This method is highly automated, requires no manual intervention, significantly improves the efficiency and reliability of unloading operations, and adapts to complex and demanding working conditions.

[0044] According to one embodiment of the present invention, as a preferred embodiment, the anti-sticking device for the cargo box, wherein the shape of the anti-sticking plate 205 is configured to adapt to the inner contour of the front panel 1 and the side panel 3 of the cargo box includes: the anti-sticking plate 205 is recessed towards the side closer to the front panel 1 of the cargo box, and transition edges are formed on both sides of the anti-sticking plate 205 for contacting the side panel 3 of the cargo box.

[0045] One feasible implementation involves specifically designing the shape of the anti-stick panel 205. The anti-stick panel 205 is not flat; instead, it forms a smooth, concave arc surface towards the front panel 1 of the cargo box. This arc surface is parallel to and maintains a certain distance from the inner contour of the front panel 1. More importantly, on both sides of the anti-stick panel 205, the panel is machined into transition edges extending outwards and backwards. These transition edges can closely adhere to or slightly contact the inner wall of the side panel 3 of the cargo box.

[0046] If a roughly flat anti-stick plate 205 is used, although this plate has a simple structure, its shape does not match the corner contour formed by the front panel 1 and the side panel 3 of the cargo box, leaving triangular gaps or dead corners between the anti-stick plate 205 and the side panel 3. Sticky materials can easily fill and adhere firmly to these dead corner areas, and cannot be removed by the action of the anti-stick plate 205, requiring manual cleaning after unloading.

[0047] This invention designs the anti-stick plate 205 as a concave shape with a transition edge, allowing it to completely cover the entire inner contour space at the junction of the front panel 1 and the side panel 3 of the cargo box. The transition edge eliminates dead corners on the sides, ensuring that the anti-stick plate 205 can act on all areas where materials may adhere. This results in a more comprehensive anti-sticking range and a more thorough anti-sticking effect, effectively solving the problem of material residue in corners.

[0048] According to one embodiment of the present invention, as a preferred embodiment, in the cargo box anti-sticking device, the support plate 203 is provided with weight reduction holes, and at the corner where the support plate 203 connects to the front plate 1 and the bottom plate 4 of the cargo box, part of the material is removed to form a weight reduction structure.

[0049] One feasible implementation involves structural optimization of the support plate 203 to reduce its weight. Multiple regularly arranged weight-reduction holes are formed on the plate body of the support plate 203. The size and distribution of these weight-reduction holes are designed to effectively remove excess material while ensuring the structural strength and supporting function of the support plate 203. Simultaneously, at the upper corner where the support plate 203 connects to the front panel 1 of the cargo box and at the lower corner where it connects to the bottom panel 4 of the cargo box, a portion of triangular or fan-shaped material is removed using a cutting process to form a weight-reduction structure, further reducing the overall mass of the support plate 203.

[0050] If a single solid steel plate without any weight-reduction design is used as the support plate 203, although the structure is simple and sturdy, its weight is also the greatest, placing unnecessary additional load on the cargo box and vehicle chassis. This additional weight will continuously occupy the vehicle's effective load share and cause the vehicle to consume more fuel or electricity when driving and lifting / unloading.

[0051] This invention achieves a lightweight design for the support plate 203 by creating weight-reduction holes and removing excess material at the corners. While ensuring its core support function remains unaffected, the weight of the support plate 203 is significantly reduced. This helps reduce the overall weight of the cargo box, allowing the vehicle to carry more effective cargo, thus improving transportation efficiency and economy. At the same time, the lighter support plate 203 also makes installation and maintenance easier.

[0052] According to one embodiment of the present invention, preferably, in the cargo box anti-sticking device, the support plate 203 faces the back of the anti-sticking plate 205, and the side of the support plate 203 that contacts the anti-sticking plate 205 matches the position of the anti-sticking plate 205 in the reset state.

[0053] One feasible implementation involves precisely designing the shape of the surfaces and edges of the support plate 203 that contact the anti-stick plate 205. The side of the support plate 203 facing the anti-stick plate 205, i.e., its back side, is machined into a support surface that matches the surface contour of the corresponding part of the anti-stick plate 205 in its reset state. In particular, the side of the support plate 203 that contacts the anti-stick plate 205 is precisely machined into a curve or zigzag line that perfectly matches the spatial position of the anti-stick plate 205 in its reset state, so that when the anti-stick plate 205 is reset, its plate body can seamlessly abut against the back and side of the support plate 203.

[0054] In the prior art, the support plate 203 is a simple flat surface or a shape that does not match the contour of the anti-stick plate 205. In this case, when the anti-stick plate 205 is reset by the counterweight 206 or the hydraulic cylinder, there may be irregular gaps between it and the support plate 203. These gaps can cause the anti-stick plate 205 to shake, knock, or even shift during vehicle movement or cargo box lifting, which not only generates noise but may also damage the connecting parts and affect the accuracy and anti-sticking effect when the anti-stick plate 205 moves again.

[0055] This invention provides a stable and highly conforming support base for the anti-stick plate 205 by precisely matching the back and contact sides of the support plate 203 with the position of the anti-stick plate 205 in its reset state. This greatly limits any unintended movement of the anti-stick plate 205 in its non-operating state, effectively eliminating shaking and noise. The stable support ensures that the anti-stick plate 205 is always in the correct position, ensuring that the device starts from the predetermined starting position each time it unloads, thereby improving the reliability and consistency of the anti-sticking effect and extending the service life of the device.

[0056] According to one embodiment of the present invention, preferably, the intersection of the plane where the support plate is located and the plane where the front panel of the cargo box is located includes: the support plate being perpendicular to the front panel of the cargo box.

[0057] One feasible implementation is that the support plate 203 is made of steel plate, and its bottom is fixedly connected to the bottom plate 4 of the cargo box by welding. The surface of the support plate 203 is arranged perpendicular to the front plate 1 of the cargo box. When resetting, the anti-stick plate 205 is attached to the back of the support plate 203. Since the support plate 203 is perpendicular to the front plate 1 of the cargo box, an angle is naturally formed between the anti-stick plate 205 and the front plate 1 of the cargo box. This angle helps to guide the material to slide smoothly during unloading, and at the same time avoids the material from directly impacting the gap between the anti-stick plate 205 and the front plate 1 of the cargo box during loading.

[0058] This invention ensures that the anti-stick plate 205 forms a uniform and stable angle structure with the front panel 1 of the cargo box by setting the support plate 203 perpendicular to the front panel 1 of the cargo box. This arrangement not only enhances the stability of the anti-stick plate 205 in the non-working state, preventing component wear and noise caused by shaking, but also effectively avoids material entering the dead corner between the anti-stick plate 205 and the front panel 1 of the cargo box. During the unloading process, the vertically set support plate 203 provides a reliable support foundation for the anti-stick plate 205, allowing it to rotate smoothly under the drive of the counterweight 206 or hydraulic cylinder, pushing the adhering material off the surface of the front panel 1 of the cargo box, improving the thoroughness of unloading and the reliability of the device.

[0059] This utility model also provides a cargo box for an off-highway dump truck, including a front panel 1, side panels 3, and a bottom panel 4. The cargo box is equipped with at least one set of the anti-sticking devices 2 described in any one of the above embodiments. Figure 1 and Figure 5 As shown.

[0060] One feasible implementation is to provide a cargo box for an off-highway dump truck, comprising a front panel 1, side panels 3, and a bottom panel 4. At least one set of anti-sticking devices is installed within the interior space of this cargo box. For example, one set can be installed at the corner where the front panel 1 intersects with one of the side panels 3. For larger cargo boxes, to achieve a more comprehensive anti-sticking effect, one set of anti-sticking devices can be installed at each corner where the front panel 1 intersects with the two side panels 3, forming a complete anti-sticking system. These anti-sticking devices are securely connected to the existing structure of the cargo box via their fasteners 201 and support plates 203, becoming an integrated part of the cargo box.

[0061] Current technologies involve temporarily installing isolated, non-standard anti-stick components inside the cargo box, or performing special treatment only in localized areas. These methods lack systematicity and overall integration; the various components may be unrelated or even interfere with each other, resulting in gaps in the anti-stick coverage area and unsatisfactory overall anti-stick effect. Furthermore, this non-integrated installation method makes the internal structure of the cargo box cluttered, increasing the complexity of manufacturing and subsequent maintenance.

[0062] This invention achieves systematization and integration of the anti-sticking function of cargo boxes by incorporating at least one set of anti-sticking devices as a standard configuration within the cargo box. This design organically combines the anti-sticking devices with the cargo box body, resulting in a more rational and orderly structural layout. It simplifies the overall design of the cargo box and reduces manufacturing costs and coordination difficulties caused by later additions or the use of multiple independent devices. This integrated cargo box facilitates mass production and makes daily maintenance more centralized and convenient for users, effectively improving the overall integrity and reliability of the product.

[0063] This utility model also provides an off-highway dump truck, including any of the cargo box anti-sticking devices or the off-highway dump truck cargo box described in any one of the claims.

[0064] One feasible implementation is to provide an off-highway dump truck that is directly equipped with the aforementioned anti-sticking device for the cargo box or directly uses an off-highway dump truck cargo box with the aforementioned built-in anti-sticking device. This means that the anti-sticking device or anti-sticking cargo box becomes a standard component of the entire vehicle. Whether installed directly during new vehicle manufacturing or retrofitted to existing vehicles, this anti-sticking solution can be matched and work collaboratively with different types of dump truck chassis and lifting mechanisms.

[0065] Existing technologies often involve anti-stick designs or accessories that are only customized for specific models or brands of cargo boxes, resulting in very low versatility. When users own multiple models of dump trucks or need to replace their cargo boxes, these specialized anti-stick devices are often difficult to transfer or adapt to new equipment, hindering the widespread adoption of the technology. Users then need to find different solutions for different vehicles, increasing procurement and management costs.

[0066] This invention significantly enhances the versatility and applicability of the technical solution by making the anti-sticking device for the cargo box or its cargo box an optional or standard configuration for off-highway dump trucks. It allows this effective anti-sticking technology to be adapted to various types and specifications of off-highway dump trucks, rather than being limited to a single cargo box model. This facilitates the promotion and application of this advanced technology, benefiting more users in mining, construction, and other fields. Ultimately, it increases the technological added value and market competitiveness of the off-highway dump truck as a whole product, meeting the common needs of different users for efficient and thorough unloading.

[0067] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be applied to various fields suitable for the embodiments of the present invention. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the embodiments of the present invention are not limited to the specific details and illustrations shown and described herein.
