Description

Technical Field

[0001] This utility model relates to the field of engine technology, specifically to a rear support for a mining truck engine. Background Technology

[0002] Mining trucks operate in harsh environments, and the engine, as a core component, requires stable support to prevent vibration and displacement from affecting its performance and lifespan. Existing support structures suffer from insufficient strength, poor adaptability, and inconvenient installation and maintenance, failing to effectively handle the complex loads encountered during mining truck operation. This impacts engine stability and the overall operational efficiency of the mining truck, thus necessitating urgent improvement. Utility Model Content

[0003] Therefore, this utility model embodiment provides a rear support for a mine car engine, in which stiffeners work in conjunction with the main support plate to effectively bear and distribute loads by utilizing their own strength and rigidity, thus avoiding stress concentration.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A rear support for a mining truck engine includes a main support plate and an engine mounting plate. The main support plate is perpendicular to the engine mounting plate. A transition connecting plate is provided between the main support plate and the engine mounting plate. A stiffening plate is provided between the main support plate and the transition connecting plate. The two sides of the stiffening plate are perpendicular to the main support plate and the transition connecting plate, respectively.

[0006] Furthermore, the thickness of the engine mounting plate is at least 10 millimeters greater than the thickness of the transition connecting plate.

[0007] Furthermore, the stiffening plate is fixedly connected to the portion of the engine mounting plate that is thicker than the transition connecting plate.

[0008] Furthermore, the stiffening plate is located on the centerline between the main support plate and the transition connecting plate, and the main support plate is provided with a number of mounting holes symmetrically on both sides of the stiffening plate.

[0009] Furthermore, the total number of mounting holes is not less than 6.

[0010] Furthermore, the length of the main support plate is at least 200 mm longer than the length of the engine mounting plate.

[0011] The present invention has the following advantages:

[0012] This utility model discloses a rear support for a mine car engine, which consists of a main support plate, stiffening plates, mounting holes, a transition connecting plate, and an engine mounting plate. It provides support and positioning. When the mine car is running, the vibrations and inertial forces generated by the engine are received by the engine mounting plate and then distributed to the main support plate via the transition connecting plate. The stiffening plates, in conjunction with the main support plate, utilize their own strength and rigidity to effectively bear and distribute the load, avoiding stress concentration. The mounting holes are connected by bolts to securely integrate the main support plate with the mine car frame, ultimately transferring the engine load to the frame. This ensures the engine maintains a stable installation under complex operating conditions, guarantees normal engine operation, and maintains the mine car's power output and operational reliability.

[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1As shown, a rear support for a mining car engine includes a main support plate 1 and an engine mounting plate 2. The main support plate 1 is connected to the main body of the mining car, and the engine mounting plate 2 is used to mount the engine. The engine mounting plate 2 is provided with a plurality of engine mounting holes to fix the engine by fastening bolts.

[0020] The main support plate 1 is perpendicular to the engine mounting plate 2. A transition connecting plate 3 is provided between the main support plate 1 and the engine mounting plate 2. A stiffening rib 4 is provided between the main support plate 1 and the transition connecting plate 3, with its two sides perpendicular to the main support plate 1 and the transition connecting plate 3, respectively. The cooperation between the stiffening rib 4, the main support plate 1, the transition connecting plate 3, and the engine mounting plate 2 effectively improves the overall strength and rigidity of the support structure, enabling it to withstand complex loads such as vibration and inertia during the operation of the mine car engine, reducing the risk of structural deformation and damage, and extending the service life of the support structure.

[0021] The thickness of the engine mounting plate 2 is at least 10 mm greater than the thickness of the transition connecting plate 3. In this embodiment, the thickness of the engine mounting plate 2 is 14 mm greater than the thickness of the transition connecting plate 3. The stiffening plate 4 fixes the portion of the engine mounting plate 2 that is thicker than the transition connecting plate 3. Since the engine mounting plate 2 needs to be provided with connection holes (i.e., the four holes at the bottom of this device), and bolts need to be installed in the connection holes, and the mounting area of ​​the engine is small and the bolts are relatively concentrated, it is necessary to increase the thickness of the engine mounting plate 2 to increase the connection strength between this technical device and the engine. Therefore, the mounting plate is thicker than the transition connecting plate and the main support plate.

[0022] The stiffening plate 4 is located on the centerline between the main support plate 1 and the transition connecting plate 3. The main support plate 1 has several mounting holes 5 symmetrically arranged on both sides of the stiffening plate 4. The total number of mounting holes 5 is not less than six. The mounting holes 5 facilitate detachable connection with the mine car frame and engine, enabling easy installation, maintenance, and replacement of components. They reliably fix the mine car engine to the frame, buffering the vibration and impact generated during engine operation, preventing excessive vibration from affecting engine performance and the reliability of connecting components. Simultaneously, they ensure the engine's stable position during mine car operation, guaranteeing the accuracy and stability of power transmission.

[0023] The length of the main support plate 1 is at least 200 mm longer than the length of the engine mounting plate 2. In this embodiment, the length of the main support plate 1 is 251 mm longer than the length of the engine mounting plate 2. This design can increase the number of mounting holes 5. Setting more mounting holes 5 can disperse the connection force between the device and the connecting body and increase the stability of the connection between the two.

[0024] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
