Description

Technical Field

[0001] This application relates to the technical field of construction machinery, and more particularly to a radiator protection device for dump trucks. Background Technology

[0002] As crucial equipment in mining, construction sites, and logistics transportation, dump trucks face severe challenges in their cooling systems under complex operating conditions. In mining operations, vehicles frequently traverse rugged terrain such as gravel and mud, making their undercarriages susceptible to impacts from large rocks and sharp objects. In construction sites, the undercarriages may be scratched by steel bars and concrete fragments. In urban logistics transportation, vehicles require frequent starting and braking, potentially damaging the chassis radiator due to bumps or road debris.

[0003] As a core component of a vehicle's powertrain, the radiator's protective performance directly impacts the engine's stable operation and the vehicle's operational efficiency. Existing radiator protection devices are mostly fixed structures, unable to adapt to varying terrain heights or changing operating conditions, thus limiting their protective effectiveness. The complex and variable operating environments of mines and construction sites place higher demands on the versatility, ease of installation, and low maintenance costs of protective devices. For example, in mining transportation scenarios, vehicles frequently need to adjust their chassis height to adapt to different slopes; existing protective devices, due to their fixed structure, cannot dynamically adapt, easily causing radiator damage. In urban transportation scenarios, users desire protective devices with selectable modules to meet diverse needs, but existing solutions suffer from insufficient integration, leading to complex installation and poor versatility.

[0004] Therefore, how to design a radiator protection system that can adapt to different working conditions and save installation space has become a technical problem that dump trucks urgently need to solve. Utility Model Content

[0005] In view of the above problems, this application provides a radiator protection device for dump trucks, which is highly adjustable and can flexibly adjust the protection position according to needs, thereby effectively adapting to complex terrain changes, reducing blind spots, and improving the convenience of installation and maintenance.

[0006] In a first aspect, embodiments of this application provide a radiator protection device for a dump truck, comprising:

[0007] A connecting bracket with a track is used to connect to the vehicle frame.

[0008] The front lower protective device is slidably installed within the track.

[0009] Locking element, used to secure the front lower guard to the connecting bracket.

[0010] In one possible implementation, the front lower guard includes a guard beam that is slidably disposed within a track.

[0011] In one possible implementation, the protective beam has a sliding part, and the connecting bracket has a sliding hole along its height direction to form a track. The locking member passes through the sliding part and is inserted into the sliding hole to fix the front lower protective device to the connecting bracket.

[0012] In one possible implementation, the connecting bracket includes a left connecting bracket and a right connecting bracket, which are connected to corresponding sliding parts.

[0013] In one possible implementation, a left connector and a right connector are provided on the protective beam to form a sliding part. The left connector and the right connector are respectively provided on both sides of the protective beam. The left connector is slidably connected to the sliding hole of the left connecting bracket, and the right connector is slidably connected to the sliding hole of the right connecting bracket.

[0014] In one possible implementation, multiple sliding holes are provided along the width direction of the connecting bracket.

[0015] In one possible implementation, the locking elements are a bolt and a nut, and the sliding part has multiple through holes. The bolt passes through the sliding part and is inserted into the sliding holes. The nut is threadedly connected to the bolt and abuts against the connecting bracket.

[0016] In one possible implementation, the left connecting bracket and the right connecting bracket are respectively fixedly mounted on both sides of the lower wing surface of the frame.

[0017] In one possible implementation, a radiator base plate is provided between the left connecting bracket and the right connecting bracket.

[0018] In one possible implementation, an intercooler guard plate is provided between the left connecting bracket and the right connecting bracket.

[0019] This application provides a radiator protection device for dump trucks.

[0024] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0026] Traditional radiator protection devices for dump trucks are mostly fixed structures, which cannot adapt to different terrain height differences or changes in working conditions, resulting in limited protective effectiveness. In complex working conditions such as mines and construction sites, the bottom of the vehicle is easily impacted or scratched, and existing devices cannot dynamically adapt to chassis height adjustments, are complex to install, and have poor versatility, making it difficult to meet users' requirements for versatility, ease of installation, and low maintenance costs of protective devices.

[0027] In view of this, this application provides a radiator protection device for dump trucks, including a connecting bracket, a front lower protection device, and a locking member. The connecting bracket has a track for connecting to the vehicle frame. The front lower protection device is slidably disposed within the track, and the locking member is used to fix the front lower protection device to the connecting bracket. By setting the track on the connecting bracket, the slidably disposed front lower protection device, and the locking member, the position of the protection device is adjustable, thereby solving the problem that fixed protection in the prior art cannot adapt to dynamic working conditions. It has high adjustability, can flexibly adjust the protection position according to needs, effectively adapting to complex terrain changes, reducing blind spots, and improving the convenience of installation and maintenance.

[0028] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0029] Combination Figures 1-2 The present application describes a dump truck radiator protection device, which includes a connecting bracket, a front lower protection device, and a locking member 8.

[0030] The connecting bracket is a component used to connect the protective device to the main structure of the vehicle. The connecting bracket can be made of metal and has sufficient strength and rigidity to withstand the impacts and vibrations experienced by the protective device during vehicle operation.

[0031] A guide structure with a track mounted on a connecting bracket is used to guide the sliding of the front underrun protection device. The track can be one or more grooves, slides, or guide rails, the shape and size of which match the sliding part of the front underrun protection device to ensure the smoothness and accuracy of the sliding process.

[0032] The front underrun protection device is located under the front of the vehicle and is a structure used to protect critical components such as the radiator from external impacts and damage from foreign objects. The device can be made of high-strength materials and can effectively absorb and disperse impact energy.

[0033] The locking element 8 is a mechanism used to secure the front underrun protection device to the connecting bracket. The locking element 8 can take various forms to ensure that the front underrun protection device can be reliably held in place after being adjusted to the required position, preventing it from moving unexpectedly during vehicle operation.

[0034] The chassis is the basic load-bearing structure of a vehicle, used to mount all major components such as the engine, body, and suspension. Connecting brackets integrate protective devices into the overall structure of the vehicle by connecting to the chassis.

[0035] The connecting bracket serves as the mounting base for vehicle protective devices. In one implementation, the connecting bracket can be designed as a single, integrated structure, such as a U-shaped or L-shaped metal profile, which is fixed to the vehicle frame by welding or riveting. In another implementation, the connecting bracket can be assembled from multiple independent plates or profiles connected by bolts or welding to accommodate different vehicle frame structures and installation requirements.

[0036] The connecting bracket is provided with a track. For example, the track can be formed as one or more raised guide rails on the surface of the connecting bracket, and the front lower guard device slides through grooves that mate with the aforementioned guide rails. As another implementation, the track can be formed as a channel inside the connecting bracket, and the edge or specific component of the front lower guard device is inserted into the channel for sliding.

[0037] The connecting bracket is connected to the vehicle frame. For example, the connecting bracket can be fixed to the corresponding holes on the vehicle frame using bolts through pre-drilled mounting holes. In another implementation, the connecting bracket can be directly welded to a specific location on the vehicle frame to provide higher structural rigidity.

[0038] The front underrun protection device provides protection for components such as the radiator at the bottom of the vehicle. For example, the front underrun protection device can be a single metal plate with sufficient thickness and strength to withstand external impacts. In another implementation, the front underrun protection device can consist of multiple interconnected protective plates to provide a more flexible protection area.

[0039] The front lower guard is slidably mounted within the track. For example, the sides of the front lower guard can be machined to match the shape of the track, allowing it to move linearly along the track. In another implementation, sliders or rollers can be mounted on the bottom of the front lower guard, which cooperate with the track to achieve smooth sliding of the front lower guard.

[0040] Locking element 8 secures the front lower guard to the connecting bracket. For example, locking element 8 can be a simple pin that passes through corresponding holes on the connecting bracket and the front lower guard to achieve fixation. In another implementation, locking element 8 can be a clamping mechanism that clamps the front lower guard onto the connecting bracket by applying pressure.

[0041] This application achieves the sliding installation of the front lower protective device via a track on a connecting bracket and secures it using locking element 8, thereby overcoming the limitations of existing fixed protective devices that cannot adapt to complex working conditions. This structure allows the protective device to be adjusted in position as needed, thus providing more flexible and effective radiator protection in rugged terrain such as mines and construction sites or in scenarios requiring frequent adjustments to chassis height, while simplifying the installation and maintenance process.

[0042] This application also discloses that the front lower protection device includes a protective beam 1, which is slidably disposed within the track.

[0043] The front underrun protection device, as a crucial protective component for the dump truck's radiator, consists of a transversely extending beam-like structure (1). This structure provides excellent lateral support and impact resistance while facilitating integration with other structures on the vehicle's underside. The protective beam (1) can be made from various materials, such as high-strength steel, aluminum alloy, or other composite materials, to meet different strength and weight requirements. Its cross-sectional shape can also be rectangular, circular, or irregular to optimize its mechanical properties and ease of installation.

[0044] The protective beam 1 is slidably mounted within the track, allowing it to reciprocate along the track on the connecting bracket. This sliding design enables the protective beam 1 to extend, retract, or be moved out as needed. For example, during radiator maintenance or repair, the protective beam 1 can be pulled out or completely removed for easier operation. The sliding mechanism can be achieved by incorporating sliding elements (such as sliders or rollers) on the protective beam 1 that engage with the track, or by having a structure that matches the track itself. The shape and dimensions of the track should precisely match the sliding portion of the protective beam 1 to ensure smooth and stable sliding and prevent accidental detachment during vehicle movement or impact.

[0045] Through the above technical solution, the front lower protective device is specifically designed as a protective beam 1, which is slidably installed within the track. This effectively solves the problems of insufficient structural stability and poor sliding that may exist in traditional front lower protective devices. The beam-like structure of the protective beam 1 provides robust lateral support, enhancing the overall impact resistance of the protective device and more effectively protecting the dump truck's radiator from external impacts or foreign object damage. The precise fit between the protective beam 1 and the track ensures the stability and reliability of the protective device during sliding. This allows operators to easily and quickly pull out or push in the protective beam 1 when the radiator needs inspection, cleaning, or maintenance, greatly improving maintenance convenience without affecting its protective performance.

[0046] This application also discloses that the protective beam 1 has a sliding part, the connecting bracket has a sliding hole along its height direction to form a track, and the locking member 8 passes through the sliding part and is inserted into the sliding hole to fix the front lower protective device to the connecting bracket.

[0047] Specifically, the protective beam 1 is provided with a sliding part, which is a structure for cooperating with the track on the connecting bracket. The sliding part can be a protrusion, groove, or edge structure integrally formed on the protective beam 1, or it can be a component manufactured separately and fixed to the protective beam 1, such as a connecting block, slider, or pin. Its main function is to provide a contact surface or structure that matches the track to guide the protective beam 1 to slide smoothly within the track and to bear the load during the sliding process. Through the design of the sliding part, good guidance and stability of the protective beam 1 can be ensured when adjusting its position.

[0048] The connecting bracket has sliding holes along its height direction, which form the track. The sliding holes can be a continuous slot or multiple holes spaced apart along the height direction. This sliding hole design along the height direction allows the protective beam 1 to move and adjust vertically within its height range. The size and shape of the sliding holes match the sliding part of the protective beam 1 to ensure smooth sliding and sufficient support strength. This structure allows for flexible adjustment of the protective beam 1 at different height positions to adapt to different working conditions or maintenance needs.

[0049] The locking element 8 is used to secure the front lower protective device to the connecting bracket. After the protective beam 1 slides to the desired position within the sliding hole of the connecting bracket via its sliding part, the locking element 8 passes through the sliding part and further into the sliding hole. The locking element 8 can be a bolt, pin, clip, or other fastener. For example, the sliding part may have pre-set holes or structures that mate with the locking element 8. When the locking element 8 passes through these holes and enters the sliding hole, a reliable connection is formed between the locking element 8 and the connecting bracket by tightening, engaging, or inserting, thereby firmly fixing the protective beam 1 at the selected height position and preventing displacement under vibration or impact.

[0050] Through the above technical solution, the sliding part on the protective beam 1 closely cooperates with the sliding hole opened along the height direction of the connecting bracket, enabling the protective beam 1 to achieve stable and controllable vertical sliding on the connecting bracket. When the protective beam 1 is adjusted to the required height, the locking member 8 can pass through the sliding part and be inserted into the sliding hole, thereby firmly fixing the front lower protective device to the connecting bracket. This design not only provides a simple and convenient height adjustment mechanism for the protective beam 1, but also ensures the stability and reliability of the protective device after it is fixed, effectively solving the problem of the protective beam 1 sliding and being unreliable in its fixation within the track, and improving the adaptability and protective effect of the dump truck radiator protection device.

[0051] This application also discloses that the connecting bracket includes a left connecting bracket 4 and a right connecting bracket 5, and the left connecting bracket 4 and the right connecting bracket 5 are connected to the corresponding sliding part.

[0052] The connecting brackets are designed as two independent components: the left connecting bracket 4 and the right connecting bracket 5. This separate design allows the connecting brackets to better adapt to the structural characteristics and installation space of the dump truck frame, and provides distributed support for the protective beam 1. The left connecting bracket 4 and the right connecting bracket 5 can be made of high-strength metal materials, such as steel or aluminum alloy, and are securely installed on the frame by bolting, welding, or other mechanical fixing methods. Depending on the geometry of the frame and the stress requirements of the protective beam 1, they can be designed as L-shaped, U-shaped, box-shaped, or other irregular structures to ensure sufficient strength and rigidity.

[0053] The protective beam 1 is equipped with at least two sliding parts, which are respectively connected to the left connecting bracket 4 and the right connecting bracket 5. This connection method ensures that the protective beam 1 can receive guidance and support from both connecting brackets when sliding along the track, thereby improving the operational stability and positioning accuracy of the entire protective device. In the fixed state, the connection between the left and right connecting brackets 5 and the corresponding sliding parts can effectively transfer the load of the protective beam 1 to the frame, enhancing the overall structural stability of the protective device.

[0054] By decomposing the connecting bracket into a left connecting bracket 4 and a right connecting bracket 5, and connecting these two independent brackets to the corresponding sliding parts on the protective beam 1, this application effectively solves the problems of insufficient lateral stability and inconvenient installation and adjustment that may exist when a single connecting bracket supports a wide protective beam 1. This double-sided support structure can more evenly distribute the load borne by the protective beam 1, especially the impacts and vibrations that may be encountered during the operation of the dump truck, thereby significantly improving the overall rigidity and deformation resistance of the protective device and ensuring the stability and reliability of the protective beam 1 under various working conditions. The independent setting of the left and right connecting brackets 5 also provides greater flexibility for the installation, disassembly, and adjustment of the protective device, making maintenance operations more convenient and better adaptable to different frame widths and protection requirements, thus improving the practicality and adaptability of the device.

[0055] In this regard, this application further proposes that the protective crossbeam 1 is provided with a left connector 2 and a right connector 3 to form a sliding part.

[0056] Specifically, the left connector 2 and the right connector 3 are structural components used to achieve a sliding connection between the protective beam 1 and the connecting bracket. They can be, for example, pins, sliders, or protrusions of a specific shape, precisely engaging with the sliding holes on the connecting bracket. The left connector 2 and the right connector 3 are respectively located on both sides of the protective beam 1; this symmetrical arrangement helps maintain the balance and stability of the protective beam 1 during sliding. The left connector 2 is slidably connected within the sliding hole of the left connecting bracket 4. The left connector 2 is designed to move smoothly along the sliding hole on the left connecting bracket 4, thereby guiding the lifting or rearward adjustment of the protective beam 1. Similarly, the right connector 3 is slidably connected within the sliding hole of the right connecting bracket 5, ensuring that the other side of the protective beam 1 is also effectively guided and supported.

[0057] Through the above technical solution, the sliding part is specifically refined into left connecting piece 2 and right connecting piece 3 set on both sides of the protective beam 1, and they are slidably connected to the sliding holes of the left connecting bracket 4 and right connecting bracket 5 respectively, thus providing a double-sided, symmetrical and stable sliding guide for the protective beam 1. This structural design can effectively distribute the load of the protective beam 1 during the sliding process, significantly reduce the tilting, jamming or swaying caused by uneven force on one side, and greatly improve the smoothness and positioning accuracy of the front lower protective device during the adjustment process. The stable sliding connection also lays the foundation for the reliable fixing of the subsequent locking piece 8, ensuring the stability of the protective device in the working state, thereby improving the reliability, ease of operation and service life of the entire dump truck radiator protective device.

[0058] This application also discloses that multiple sliding holes are formed along the width direction of the connecting bracket.

[0059] Specifically, the sliding hole is a structure opened along the height direction of the connecting bracket to form a track. Its function is to guide the sliding part of the protective beam 1 to move and to provide a passage for the locking member 8, thereby realizing the positioning and fixing of the front lower protective device.

[0060] Multiple sliding holes are formed along the width direction of the connecting bracket, and multiple independent sliding holes are arranged on the connecting bracket along the width direction (i.e., the direction perpendicular to the height direction of the connecting bracket). These sliding holes can be separate circular holes, elliptical holes, or short slot-shaped holes, forming a series of selectable locking positions in the width direction of the connecting bracket. For example, two or more rows of sliding holes can be provided, each row extending along the height direction of the connecting bracket and side by side along the width direction. Alternatively, there can be multiple independent holes arranged along the width direction, each hole capable of aligning with the through hole on the sliding part and accommodating the locking element 8. This design allows the front lower protective device to be precisely locked in more discrete positions after sliding adjustment, to adapt to different protection requirements or maintenance operations.

[0061] By employing the aforementioned technical solution, multiple sliding holes are created along the width of the connecting bracket, significantly increasing the selectable locking positions of the front lower protective device during adjustment. When the position of the front lower protective device needs adjustment, the operator can move the sliding part of the protective beam 1 to a position aligned with any of the sliding holes, and then secure it using the locking element 8. This multi-point locking mechanism provides more precise positioning capabilities, enabling the protective device to adapt more accurately to different working conditions or maintenance scenarios. For example, the protective device can be adjusted and locked outwards when more heat dissipation space is needed, or adjusted and locked inwards when stronger protection is required. Simultaneously, the design of multiple sliding holes enhances the stability of the fit between the locking element 8 and the connecting bracket, reducing potential shaking or displacement caused by a single locking point, thereby improving the reliability and safety of the entire protective device.

[0062] This application further proposes that the locking element 8 is specifically a combination of a bolt and a nut. Bolts and nuts, as common mechanical fasteners, have the advantages of simple structure, reliable connection, convenient assembly and disassembly, and the ability to provide a large clamping force.

[0063] A bolt typically consists of a head and a shank, with external threads on the shank; a nut has internal threads that match the bolt's threads. The use of bolts and nuts allows for the fastening of components.

[0064] Multiple through holes are provided on the sliding part. These through holes are typically arranged along a predetermined path, such as the length or width of the sliding part, forming a series of fixing points through which bolts can pass. The design of multiple through holes allows the front lower guard device to be precisely locked at different predetermined positions during sliding, thus meeting the positional requirements of the guard device under different working conditions. For example, when it is necessary to adjust the protrusion of the guard device to adapt to different working environments or maintenance needs, this can be achieved by selecting different through hole positions. These through holes can be circular, elliptical, or oblong, and their dimensions match the diameter of the bolt to ensure that the bolt can pass through smoothly and provide stable support.

[0065] When fixing the front lower guard device, the bolt first passes through a selected hole on the sliding part, and then further passes through the corresponding sliding hole on the connecting bracket. The insertion of the bolt initially fixes the sliding part and the connecting bracket in a direction perpendicular to the sliding direction, restricting the relative movement of the front lower guard device. By selecting different holes on the sliding part, the position of the bolt inserted into the sliding hole can be adjusted, thereby achieving position adjustment of the front lower guard device within the track. After the bolt passes through the sliding part and the sliding hole, the nut connects to the bolt's thread, and by tightening the nut, it abuts against the outer surface of the connecting bracket. The tightening of the nut generates an axial clamping force, pressing the sliding part and the connecting bracket tightly together, thus achieving reliable fixing of the front lower guard device. The threaded connection and abutment provide strong friction to resist external vibration and impact, effectively preventing the front lower guard device from loosening or shifting during operation. Due to the detachability of the bolt and nut, adjusting, disassembling, or replacing the front lower guard device becomes simple and quick, greatly improving maintenance efficiency and operational convenience.

[0066] Through the above technical solution, the locking component 8 is specifically designed as a combination of bolts and nuts, with multiple through holes on the sliding part. This effectively solves the problems of inflexible fixing, insufficient positioning accuracy, and easy loosening of the locking component 8 in the prior art. When it is necessary to adjust the position of the front lower guard device, the operator only needs to loosen the nut, remove the bolt from the current through hole and sliding hole, slide the front lower guard device to the desired position, align the corresponding through hole on the sliding part with the sliding hole of the connecting bracket, reinsert the bolt, and tighten the nut. This makes the position adjustment of the front lower guard device precise and convenient, and allows for flexible adjustment of the protrusion or height of the guard device according to different operational or maintenance requirements. The threaded connection of the bolt and nut provides strong clamping force, ensuring a tight fit between the sliding part and the connecting bracket, effectively resisting the severe vibration and impact generated by the dump truck under complex working conditions. This ensures the stability and reliability of the front lower guard device in long-term use, significantly improving the overall performance and service life of the guard device.

[0067] This application also discloses that the left connecting bracket 4 and the right connecting bracket 5 are respectively fixedly installed on both sides of the lower wing surface of the vehicle frame.

[0068] The left connecting bracket 4 and right connecting bracket 5 are components of the connecting bracket system, serving as bridges connecting the entire protective device to the chassis, bearing the weight of the front underrun protection device and potential impact forces. The left connecting bracket 4 and right connecting bracket 5 can be made of high-strength metal materials, such as structural steel, to ensure sufficient rigidity and strength. The chassis is the basic load-bearing structure of the dump truck, composed of longitudinal beams and crossbeams, possessing extremely high strength and rigidity, supporting the vehicle's engine, cab, cargo box, and all other components. The chassis typically uses channel steel or a box-shaped cross-section, with its lower flange being the bottom horizontal plane of the chassis longitudinal beams. The lower flange is chosen as the connection point usually because of its high structural strength and ease of installation and maintenance.

[0069] The two sides are the left and right sides of the frame longitudinal beams. Fixing the left connecting bracket 4 and right connecting bracket 5 to both sides of the lower wing surface of the frame creates a wide and stable support base, helping to distribute loads and improve the stability of the entire protective device. Fixing is typically achieved through bolting, welding, or riveting. Bolted connections offer detachability for easy maintenance and replacement; welding provides greater structural integrity and rigidity; riveting is suitable for applications requiring shear forces. The specific fixing method will be selected based on the vehicle design, material properties, and the stress conditions of the protective device.

[0070] By fixing the left connecting bracket 4 and the right connecting bracket 5 to both sides of the lower wing surface of the vehicle frame, the protective device of this application can be directly and securely connected to the most robust load-bearing structure of the vehicle, making full use of the inherent high strength and rigidity of the vehicle frame and providing an extremely reliable support foundation for the entire front lower protection device. Since the connecting brackets are firmly fixed to both sides of the lower wing surface of the vehicle frame, the vibration and displacement generated by the protective device during vehicle travel or operation can be effectively suppressed, ensuring that the front lower protection device is always in the preset protective position. This allows for more effective absorption and dispersion of external impact forces, significantly improving the protective performance of the radiator and related components and the overall stability of the device.

[0071] In this regard, this application further proposes that a radiator bottom cover plate 7 be provided between the left connecting bracket 4 and the right connecting bracket 5.

[0072] The radiator underbody guard 7 is a plate-like structure installed under the vehicle radiator to protect the radiator and its surrounding components from external impacts, splashes, or ground obstacles. It provides a physical barrier to prevent stones, mud, branches, and other debris from directly impacting or scratching the bottom of the radiator, thereby extending the radiator's service life and ensuring its normal operation. The guard can be made of high-strength steel, aluminum alloy, or other composite materials to balance strength, weight, and corrosion resistance. It can be installed on the vehicle frame or a structure connected to the frame, such as the left connecting bracket 4 and right connecting bracket 5 in this application, to form a robust protective unit. In some embodiments, the radiator underbody guard 7 can be designed to be removable for easy radiator inspection or replacement.

[0073] By installing a radiator bottom guard plate 7 between the left connecting bracket 4 and the right connecting bracket 5, the protective device provides more comprehensive bottom protection for the dump truck's radiator. When the vehicle travels on rough roads or encounters ground obstacles, the radiator bottom guard plate 7 effectively withstands impacts and splashes from below, preventing direct damage to the radiator body and its connecting pipes. This significantly reduces the risk of radiator damage due to external factors, reduces maintenance costs and downtime, and works in conjunction with the sliding protective beam 1 to provide flexible maintenance access while ensuring continuous protection of critical areas of the radiator, thereby improving the reliability and durability of the entire cooling system.

[0074] This application also discloses that an intercooler guard plate 6 is provided between the left connecting bracket 4 and the right connecting bracket 5.

[0075] The intercooler guard plate 6 is a structural component used to protect the intercooler. It can be made of high-strength metal materials (such as steel plates or aluminum alloy plates) and has sufficient rigidity and impact resistance. The shape and size of the intercooler guard plate 6 are designed to effectively cover the area where the intercooler is located, preventing external foreign objects from directly impacting the intercooler. The guard plate can be fixed between the left connecting bracket 4 and the right connecting bracket 5 in various ways, such as by bolting, welding, or snap-fit ​​connection, to ensure that it will not loosen or fall off during vehicle operation. To ensure the intercooler's heat dissipation performance, the intercooler guard plate 6 can be designed with ventilation holes or a mesh structure, providing protection while allowing air circulation to avoid affecting the normal operating efficiency of the intercooler.

[0076] By installing an intercooler shield 6 between the left connecting bracket 4 and the right connecting bracket 5, the shield effectively shields and protects the intercooler from direct impact and erosion by splashes, gravel, mud, and other foreign objects from the front or bottom of the vehicle. This significantly reduces the risk of intercooler damage under harsh operating conditions, ensuring its normal operation, maintaining engine intake efficiency and power output, and avoiding repair costs and downtime due to intercooler damage. The intercooler shield 6, together with the left connecting bracket 4 and the right connecting bracket 5, forms an integrated protective structure, enhancing the rigidity and impact resistance of the entire protective device and providing more comprehensive and reliable front-end protection for dump trucks.

[0077] Compared to existing fixed radiator protection devices, the dump truck radiator protection device of this application achieves dynamic adjustability of the protection device height through the cooperation of a connecting bracket, a slidingly mounted lower front protection device, and a locking element 8. This design allows the vehicle to flexibly adjust the protection level according to different working conditions (such as terrain height and protection requirements), effectively solving the problems of limited protection effect and inability to adapt to changing working conditions of traditional fixed devices. At the same time, its simple structure and convenient operation reduce the complexity of installation and maintenance, improving the reliability and operational efficiency of the dump truck.

[0078] Finally, it should be noted that other embodiments of this utility model will readily conceive of by those skilled in the art upon consideration of the specification and practice of the utility model disclosed herein. This utility model is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this utility model and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this utility model is limited only by the appended claims.
