Description

Technical Field

[0001] This utility model relates to the field of mining car frame technology, specifically a cast steel reinforced frame for mining cars. Background Technology

[0002] The chassis serves to support and connect the various components of a car and withstand various loads from both inside and outside the vehicle. The chassis is the assembly base for the entire car; most of the car's parts and assemblies are fixed in place by the chassis, ensuring they maintain their correct relative positions.

[0003] The mine car frame is a crucial piece of transportation equipment in mining production, primarily used for conveying coal (ore) or gangue, as well as other bulk materials. It is the main load-bearing component of the mine car, upon which all other parts of the car are mounted. Currently, during operation, the mine car frame bears complex loads, with collision forces being the primary cause of frame damage. Furthermore, the mine car frame bears the entire weight of the car and various loads generated during operation, making it susceptible to frame breakage during transport.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To address the above deficiencies, this utility model provides a reinforced cast steel frame for mining cars, thereby solving the problem of reinforcing the cast steel frame of mining cars.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A reinforced cast steel frame for a mining car includes a left longitudinal beam and a right longitudinal beam. A front crossbeam is connected between the front ends of the left and right longitudinal beams, and a rear crossbeam is connected between the rear ends of the left and right longitudinal beams. A reinforcing structure is provided between the left and right longitudinal beams.

[0008] The reinforcing structure includes a set of L-shaped outer beams, several channel-shaped intermediate beams, a set of channel-shaped inner beams, an engine mount crossbeam, an intermediate crossbeam, and a set of rear leaf spring crossbeams. The set of L-shaped outer beams is located outside the left and right longitudinal beams, the several channel-shaped intermediate beams are located inside the left and right longitudinal beams, and the set of channel-shaped inner beams is located inside the left and right longitudinal beams. The engine mount crossbeam is installed between the front ends of the set of channel-shaped inner beams, the intermediate crossbeam is installed at the center between the set of channel-shaped inner beams, and the set of rear leaf spring crossbeams is installed between the rear ends of the set of channel-shaped inner beams.

[0009] Furthermore, a set of L-shaped outer beams, several channel-shaped intermediate beams, and channel-shaped inner beams are riveted together.

[0010] Furthermore, a set of L-shaped outer beams, several channel-shaped intermediate beams, and a set of channel-shaped inner beams each have several corresponding stress holes.

[0011] Furthermore, an engine rear suspension bracket is installed on the inner side of the front end of the left longitudinal beam, and a battery bracket is installed on the outer side of the front end of the right longitudinal beam.

[0012] Furthermore, the front crossbeam and the engine mount crossbeam are connected to front leaf springs at both ends, and a set of rear leaf spring crossbeams are connected to rear leaf springs at both ends.

[0013] Furthermore, bumpers are installed at the front ends of the left and right longitudinal beams, and the rear ends of the left and right longitudinal beams are connected to the rear crossbeams via corner crossbeam assemblies.

[0014] This utility model provides a reinforced cast steel frame for a mining car, which has the following advantages: the left and right longitudinal beams are riveted together by a set of L-shaped outer beams, several channel-shaped middle beams and a set of channel-shaped inner beams. The inner layer uses high-strength but heavy materials to ensure the basic structural strength of the frame, while the outer layer uses lighter materials to reduce weight. The combination of the two can optimize weight while ensuring strength, which helps to enhance the stability of the frame when subjected to pressure, tension and torsion.

[0015] A set of L-shaped outer beams, several channel-shaped intermediate beams, and a set of channel-shaped inner beams each have several corresponding stress holes, which achieves the weight reduction of the frame and can also be used to distribute the stress on the frame and extend the service life of the frame.
