Description

Technical Field

[0001] This utility model relates to the field of mining truck technology, and in particular to a mining truck body structure. This utility model also relates to a mining truck having the aforementioned mining truck body structure. Background Technology

[0002] Mining trucks are off-highway vehicles, also known as off-highway dump trucks. They are special transport vehicles designed for the mining environment. They typically have powerful engines and high load capacity. At the same time, mining trucks often use large-size tires to cope with the rugged roads and complex terrain conditions in mines.

[0003] To adapt to the complex and ever-changing working environment of mines, most existing mining trucks adopt an offset cab design, with the cab positioned at the front left of the vehicle. This allows the driver to better observe the road conditions and surrounding environment ahead, improving driving safety. At the same time, the offset cab also reduces dust and noise interference to the driver to some extent, enhancing the driving experience.

[0004] During operation, mining trucks generate significant vibrations due to complex road conditions, heavy loads, and the operation of power systems such as engines. These vibrations are transmitted to the cab through the vehicle structure, affecting the driver's comfort. Furthermore, the cab is subjected to prolonged vibration, which can cause fatigue damage to structural components and loosen electrical parts, ultimately reducing the overall safety of the vehicle. Utility Model Content

[0013] Furthermore, a connecting beam is provided between the first support frame and the engine guard, and the hood is connected to the connecting beam by a hinge.

[0014] Furthermore, a central crossbeam connects the first support frame and the second support frame, and the central crossbeam, together with the first support frame and the second support frame, forms an "H"-shaped support structure.

[0015] Furthermore, a reinforcing beam is provided between the engine guard and the first support frame, and the reinforcing beam is located below the connecting beam; the top of the reinforcing beam is provided with a support column connected to the connecting beam, and the support column is a plurality of columns spaced apart along the length direction of the reinforcing beam.

[0016] Furthermore, the front suspension beam is provided with step devices for the upper and lower parts of the mining vehicle at both ends; and / or, the front suspension beam is provided with at least one of a bumper and a crash guard on the side facing the front of the vehicle.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] The mining truck body structure described in this utility model, through the setting of the first shock absorber, when the cab is connected to the front suspension beam and the rear suspension bracket, the first shock absorber can significantly attenuate and absorb the vibration and impact from the mining truck frame, thereby reducing the overall vibration of the cab, reducing the risk of fatigue cracking of the cab's structural components and loosening of electrical components due to vibration, and improving the driving comfort and overall safety of the mining truck.

[0019] In addition, a maintenance platform is located on the other side of the frame. The maintenance platform is mounted on the front suspension crossbeam and the frame via first and second platform supports, allowing the driver or accompanying personnel to climb onto the maintenance platform for maintenance operations.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] This embodiment relates to a mining truck body structure. In terms of overall structure, as follows... Figure 1 , Figure 3 As shown, this embodiment includes a front suspension beam 2 located at the front end of the frame 1 of the mining truck, and a rear suspension bracket 101 located on one side of the frame 1. The cab 4 of the mining truck is mounted on the front suspension beam 2 and the rear suspension bracket 101, and is arranged near one end of the front suspension beam 2. Both the front suspension beam 2 and the rear suspension bracket 101 are connected to the cab 4 through a first shock absorber 3.

[0039] As described above, with the first shock absorber 3 installed, when the cab 4 is connected to the front suspension beam 2 and the rear suspension bracket 101, the first shock absorber 3 can significantly attenuate and absorb vibrations and impacts from the mining truck frame 1, thereby reducing the overall vibration of the cab 4 and improving the driving comfort of the mining truck. At the same time, it reduces the risk of fatigue cracking of the structural components of the cab 4 due to vibration and loosening of electrical components, protecting the cab 4 and the electrical system, and improving the overall safety of the vehicle.

[0040] Based on the above overall introduction, specifically, as follows: Figure 2 , Figure 3 As shown, in this embodiment, a first platform bracket 102 is provided on the other side of the vehicle frame 1, relative to the rear suspension bracket 101. A second platform bracket 201 is provided at the other end near the front suspension crossbeam 2, relative to the cab 4. A maintenance platform 5 is provided on both the first platform bracket 102 and the second platform bracket 201, and both the first platform bracket 102 and the second platform bracket 201 are connected to the maintenance platform 5 via a second shock absorber 501.

[0041] The first platform bracket 102 connects the front suspension crossbeam 2 and the maintenance platform 5, ensuring that the front and rear ends of the maintenance platform 5 are at a uniform height and that the maintenance platform 5 is in a level position. The maintenance platform 5 allows the driver or accompanying personnel to perform maintenance and repairs on the engine compartment or perform other maintenance operations, improving work efficiency and convenience. Simultaneously, the second shock absorber 501 reduces the vibration of the maintenance platform 5, preventing fatigue damage or loosening due to vibration, and improving the stability and service life of the maintenance platform 5 connection.

[0042] In specific implementation, the first shock absorber 3 and the second shock absorber 501 in this embodiment can adopt a sandwich structure shock absorber well known to those skilled in the art, such as a rubber shock absorber, a spring shock absorber, or a silicone oil shock absorber, which can effectively connect the cab 4 and the maintenance platform 5 and reduce the transmission of vibration. In addition, the maintenance platform 5 is equipped with a railing, and a rearview mirror is installed on the railing near the direction of travel of the mining truck. The railing can prevent personnel from falling off the maintenance platform 5.

[0043] To further improve the connection between the maintenance platform 5 and the frame 1, a third platform support 103 is provided on the frame 1 in this embodiment, located between the first platform support 102 and the second platform support 201. A second shock absorber 501 is provided on the third platform support 103, and it is connected to the maintenance platform 5 through the second shock absorber 501. The third platform support 103 provides support for the middle of the maintenance platform 5, preventing it from deforming and collapsing due to foot traffic. Simultaneously, the second shock absorber 501 on the third platform support 103 prevents vibrations from the frame 1 from being transmitted to the maintenance platform 5.

[0044] As a specific form of implementation, such as Figure 3 , Figure 4 As shown, in this embodiment, a hood support assembly 6 is provided between the rear suspension bracket 101 and the first platform bracket 102, and an engine guard 202 is provided on the front suspension crossbeam 2. A cabin sidewall 7 is provided on the side of the hood support assembly 6 and the engine guard 202 facing the maintenance platform 5, and an openable hood 8 is provided between the top of the hood support assembly 6 and the top of the engine guard 202. Thus, the cabin sidewall 7, the engine guard 202, the hood support assembly 6, the hood 8, and the sidewall of the cab 4 together form the engine compartment, preventing the engine and corresponding electrical equipment from being exposed. Simultaneously, the hood 8 allows for easy access to the engine inside the cabin for maintenance and repair.

[0045] Specifically, the hood support assembly 6 includes a base beam 601, and a first support frame 602 and a second support frame 603 located on top of the base beam 601. One end of the base beam 601 is connected to the first platform support 102, and the other end overlaps one side of the rear suspension support 101, while the second support frame 603 is connected to the cabin sidewall 7. The base beam 601 facilitates the installation of the first support frame 602 and the second support frame 603. The first support frame 602 effectively connects and supports the hood 8, and the second support frame 603 provides an installation foundation for the cabin sidewall 7.

[0046] Based on this, a connecting beam 801 is provided between the first support frame 602 and the engine guard 202 in this embodiment. The hood 8 is connected to the connecting beam 801 via a hinge. The connecting beam 801 provides a mounting base for the hood 8, allowing the hood 8 to be opened from the inspection platform towards the driver via the hinge, thus facilitating personnel on the maintenance platform 5 to open the hood 8 for maintenance work. In specific implementation, the other side of the hood 8 overlaps with the engine compartment side wall 7, and both the hood 8 and the engine compartment side wall 7 are provided with a latch 701 to keep the hood 8 closed, preventing the hood 8 from being accidentally opened. Simultaneously, the hood 8 is provided with a handle 804 to facilitate the opening and closing of the hood 8.

[0047] Since the first support frame 602 and the second support frame 603 are only connected to the bottom beam 601 at their bottom, the first support frame 602 and the second support frame 603 are prone to tipping over in the width direction of the mining car, resulting in damage to the engine compartment structure. Therefore, in this embodiment, a central crossbeam 604 connects the first support frame 602 and the second support frame 603, and the central crossbeam 604, the first support frame 602, and the second support frame 603 form an "H"-shaped support structure.

[0048] By setting the central crossbeam 604, it is possible to provide lateral support for the first support frame 602 and the second support frame 603. The resulting "H"-shaped support structure can prevent the first support frame 602 and the second support frame 603 from tipping over in the width direction of the mining car, thereby improving the overall structural strength and stability of the engine compartment support assembly and ensuring the connection stability between the engine cover 8 and the engine compartment side wall 7.

[0049] Furthermore, to prevent the connecting beam 801 from bending and deforming due to the weight of the hood 8, a reinforcing beam 802 is provided between the engine guard 202 and the first support frame 602 in this embodiment. The reinforcing beam 802 is located below the connecting beam 801. The top of the reinforcing beam 802 is provided with a support column 803 connected to the connecting beam 801, and multiple support columns 803 are spaced apart along the length of the reinforcing beam 802. Through the installation of the reinforcing beam 802, the force on the connecting beam 801 can be transmitted to the reinforcing beam 802 through the support columns 803. The reinforcing beam 802 and the various support columns 803 jointly support the connecting beam 801 to prevent bending. Simultaneously, the connecting beam 801, the reinforcing beam 802, and the various support columns 803 constitute a fence structure, which has good structural strength and connects the first support frame 602 and the engine guard 202, effectively connecting the engine guard 202 and the first support frame 602, thereby improving the overall structural strength of the engine compartment.

[0050] Finally, in this embodiment, both ends of the front suspension beam 2 are respectively equipped with step devices 203 for getting on and off the mining truck. The driver or accompanying personnel can enter the cab 4 or climb onto the maintenance platform 5 through these step devices. Simultaneously, in this embodiment, the front suspension beam 2 facing the front of the vehicle is equipped with at least one of a bumper 204 and a crash barrier 205. The bumper 204 and crash barrier 205 mitigate the impact of ore and other objects on the mining truck, providing protection and improving the safety of the mining truck. In specific implementation, this embodiment simultaneously provides a bumper 204 and a crash barrier 205. The crash barrier 205 is connected to the top of the front suspension beam 2 and the side facing the front of the vehicle via a bracket, and a window is formed on the bumper large enough for the bracket to pass through, ensuring the connection strength of the crash barrier 205.

[0051] In summary, the mining truck body structure of this embodiment, through the setting of the first shock absorber 3, when the cab 4 is connected to the front suspension beam 2 and the rear suspension bracket 101, the first shock absorber 3 can significantly attenuate and absorb the vibration and impact from the mining truck frame 1, thereby reducing the overall vibration of the cab 4, reducing the risk of fatigue cracking of the structural components of the cab 4 due to vibration and loosening of electrical components, improving the driving comfort and overall safety of the mining truck, and thus having good practicality.

[0054] The mining truck described in this embodiment, through the above-mentioned mining truck body structure, utilizes the characteristics of the first shock absorber 3 to absorb vibration and impact, reducing the transmission of vibration from the frame 1 to the cab 4, thereby reducing the vibration of the cab 4, avoiding fatigue damage to the structural components of the cab 4 and loosening of electrical components, thus improving the driving comfort of the mining truck and extending its service life.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
