Description

Technical Field

[0001] This utility model relates to the field of wide-body dump truck technology, and in particular to a bottom plate structure for adding protection to the rear of a wide-body dump truck. Background Technology

[0002] Dump trucks (also known as tipper trucks) are widely used transport vehicles in mining, construction, logistics, and other fields. Their core feature is the use of a hydraulic lifting mechanism to tilt the cargo box, enabling rapid and automatic unloading. The cargo box, as the core load-bearing component of the dump truck, is mainly used to hold and transport bulk materials (such as sand, coal, ore, soil, and garbage). The floor plate is the foundation and key load-bearing component of the cargo box structure, directly bearing the enormous weight and impact force of the loaded material, as well as the friction and inertial forces during unloading.

[0003] When a dump truck is in operation, it needs to lift the cargo box. After lifting by hydraulic cylinders, it requires safety supports to prevent accidents caused by lifting failure. However, accidents may occur, such as hydraulic cylinder failure. In such cases, the safety support rods alone cannot effectively support the weight of the entire cargo box, easily creating safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a bottom plate structure for adding protection to the rear of a wide-body dump truck, which solves the technical problem of insufficient safety after the cargo box of a wide-body dump truck is lifted in the prior art.

[0005] This application discloses a bottom plate structure for adding protection to the rear of a wide-body dump truck, including: The base plate has an upwardly inclined, raised section at its tail end; A tail fixing plate is installed at the bottom of the raised section; A central through beam is installed at the bottom of the base plate; Longitudinal beams are installed at the bottom of the base plate; A flip-up support is installed at the bottom of the longitudinal beam; A stone-discharging device mounting base is provided at the bottom of the longitudinal beam, and the stone-discharging device mounting base is located outside the flip-up seat support; The strut limiting assembly is installed at the bottom of the base plate.

[0006] This application designs the base plate by using a combination of a raised tail section and a fixed tail plate, which facilitates subsequent installation and fixation via pins after lifting, thereby ensuring safety after lifting.

[0007] Based on the above technical solution, the embodiments of this application can be further improved as follows: Furthermore, the stone-discharging device mounting base includes: The mounting plate is connected to the central through beam on one side and to the longitudinal beam on the other side. A connecting plate is provided on the mounting plate, and a limiting protrusion is provided at the bottom of the connecting plate. The beneficial effect of this step is that the limiting protrusion can effectively limit the rock discharge rod.

[0008] Furthermore, there are at least two sets of stone ejector mounting seats, and the stone ejector mounting seats are respectively located on both sides of the flip seat support. The beneficial effect of this step is that multiple stone ejector mounting seats can facilitate the improvement of safety during driving.

[0009] Furthermore, the strut limiting assembly includes: A limiting groove is provided on the base plate; A limiting reinforcing rib is provided on the outside of the limiting groove. The beneficial effect of this step is that the limiting reinforcing rib can ensure the stability of the limiting groove after installation.

[0010] Furthermore, it also includes a limiting frame assembly, which is installed at the bottom of the base plate. The advantage of this step is that it facilitates the cargo box base plate falling onto the vehicle frame.

[0011] Furthermore, the limiting frame assembly includes: A limiting plate is installed on the side of the longitudinal beam; The limiting post is installed on the outside of the limiting plate. The beneficial effect of this step is that the limiting post and the limiting plate work together to ensure that the cargo box floor can be stably placed within the gap of the vehicle frame.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. This application uses a tail-end lifting section and a tail-end fixing plate that work together and are then fixed with a pin shaft to ensure safety after lifting.

[0013] 2. This application does not require large-area welding, which greatly reduces the manufacturing time. At the same time, it has high structural strength and can effectively improve safety performance. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "setup," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1: like Figure 1-3As shown in the embodiment of this application, a bottom plate structure for adding protection to the rear of a wide-body dump truck is disclosed. Specifically, a rear fixing plate is added to the rear of the bottom plate structure. After the cargo box is lifted to a certain angle, it is connected to the main frame through a pin shaft, which plays a secondary protection role. When the lifting system fails after lifting, the rear fixing plate will hold the cargo box to prevent it from falling, thus playing a very good protective role.

[0021] like Figure 1 As shown, the specific structure of this application includes: The bottom plate 1 has an upwardly inclined raised section 2 at its tail end. The raised section 2 at the tail end of the bottom plate 1 is used for support and facilitates subsequent fixation by the tail fixing plate 3. The bottom plate 1 is used to place the cargo box. The rear fixing plate 3 is installed at the bottom of the raised section 2. Because the raised section 2 is curved upward, the rear fixing plate 3 can be fixed to the vehicle frame by a pin after the cargo box is lifted, thereby playing a secondary protection role. Preferably, the rear fixing plate 3 is a triangular plate. A central through beam 4 is installed at the bottom of the base plate 1. There are multiple central through beams 4, which are arranged in parallel and spaced apart to ensure the strength of the base plate 1. The longitudinal beam 5 is installed at the bottom of the base plate 1. The longitudinal beam 5 intersects with the through beam 4 to form a reinforcing member of the base plate and ensure its strength. The flip-up support 6 is installed at the bottom of the longitudinal beam 5 to facilitate the subsequent flipping of the base plate 1; The stone-discharging device mounting base 7 is located at the bottom of the longitudinal beam 5 and is situated outside the flip-up seat support 6. The stone-discharging device mounting base 7 is used to install the stone-discharging device, thereby improving the installability. The strut limiting assembly 8 is installed at the bottom of the base plate 1. The strut limiting assembly 8 helps to ensure that the strut is stably positioned therein, thereby ensuring the stability of the entire cargo box.

[0022] like Figure 2 As shown, to ensure the stability of the stone-discharging device after installation, the stone-discharging device mounting base 7 includes: Mounting plate 701 is connected to the central through beam 4 on one side and to the longitudinal beam 5 on the other side; A connecting plate 702 is disposed on the mounting plate 701, and a limiting protrusion 703 is provided at the bottom of the connecting plate 702; the limiting protrusion 703 serves as a front extended protrusion to prevent the stone ejector rod from swinging forward and colliding with the tire.

[0023] Specifically, there are at least two sets of the stone ejector mounting base 7, and the stone ejector mounting base 7 is located on both sides of the tilting seat support 6. The stone ejector mounting base 7 can ensure the stable movement of the dump truck.

[0024] To ensure stable lifting of the cargo box, it is necessary to ensure that the support rod remains stably within the support rod limiting assembly 8. The design of this support rod limiting assembly 8 includes, for example... Figure 3 As shown, the strut limiting assembly 8 includes: A limiting groove 801 is provided on the base plate 1. The limiting groove 801 can be a channel steel part, which is convenient to cooperate with the support rod to form a support. A limiting reinforcing rib 802 is disposed on the outside of the limiting groove 801. The limiting reinforcing rib 802 is used for reinforcement, that is, multiple limiting reinforcing ribs 802 are located on both sides of the limiting groove 801, thereby ensuring the stability of the strut limiting assembly 8.

[0025] After the base plate 1 and the cargo box are connected, they need to be placed on the vehicle frame. Therefore, this application also includes a limiting frame assembly 9, which is installed at the bottom of the base plate 1 and cooperates with the gap between it and the vehicle frame to achieve limiting.

[0026] Specifically, the limiting frame assembly 9 includes: The limiting plate 901 is installed on the side of the longitudinal beam 5. Specifically, the bottom of the limiting plate 901 is wedge-shaped, which allows it to better extend into the gap of the frame and ensure stability. The limiting post 902 is installed on the outside of the limiting plate 901.

[0027] Further explanation is provided regarding this application: This application mainly focuses on the design of the rear of the dump truck. It includes not only a raised section 2 but also a rear fixing plate 3. After the cargo box is raised to a certain angle, it connects to the main frame via a pin, providing secondary protection. If the lifting system fails after lifting, the rear fixing plate 3 will hold the cargo box in place, preventing it from falling and providing excellent protection.

[0028] In this application, the base plate 1 is the main structure. The central through beam 4 passes through the longitudinal beams 5 (divided into secondary longitudinal beams and main longitudinal beams) and is welded to the base plate 1. At the same time, a rear tail beam is provided at the bottom of the raised section 2 to ensure stability. When the cargo box is raised to a certain height, the rear fixing plate on the base plate is connected and fixed to the frame assembly by a pin to prevent the cargo box from falling and causing safety hazards, thus playing a safety protection role.
