Description

Technical Field

[0001] This utility model relates to a half-bridge structure for mining vehicles, belonging to the technical field of mining vehicles. Background Technology

[0002] The chassis of a mining vehicle is the core part of its bottom. It is mainly used to support the various components of the vehicle and withstand the huge loads and impacts generated during mining operations. It usually integrates a shock absorption system to reduce the impact on the chassis when driving on rough terrain and protect other parts of the vehicle.

[0003] Currently, most mainstream mining engineering vehicles use axle mechanisms or leaf spring damping frames, as well as direct-drive wheels without damping, to meet vibration reduction requirements. However, when facing high-level operating conditions with speeds ranging from 5 to 20 km / h, and in environments with uneven road surfaces, narrow running surfaces, and limited turning space, existing axle, leaf spring damping frames, and direct-drive wheels cannot meet the demands of these complex operating environments. They not only fail to simultaneously meet the functional requirements of rotation, running, vibration reduction, and maintenance-free operation, but also increase the weight, size, design and maintenance costs, and inspection risks of the traveling mechanism.

[0004] Therefore, there is still a lack of a frame structure that can be adapted to mining vehicles and integrates slewing operation and shock absorption. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a half-axle structure for mining vehicles, connecting the frame and wheels of the mining vehicle. The half-axle structure includes:

[0006] The frame has two vertically arranged guide rods fixed inside it, and the top of the frame is connected to the vehicle frame through a slewing mechanism.

[0007] The traveling mechanism fixing frame includes two bushings sleeved on two guide rods and a floating plate connecting the two bushings. The floating plate is connected to the wheel hub of the wheel through the traveling mechanism. Both bushings are fixed to the frame.

[0008] A first elastic element connects the upper end of the bushing and the top of the frame, and the first elastic element is sleeved on the guide rod;

[0009] The second elastic element connects the lower end of the bushing to the bottom of the frame.

[0010] Furthermore, the frame is a vertically arranged rectangular frame. The floating plate is an annular plate, and a traveling mechanism connecting the wheel hub is assembled inside the floating plate.

[0011] Furthermore, the walking mechanism is a wheel-side motor.

[0012] Furthermore, the first elastic element is a spring, the lower end of which is compressed and fixed to the top of the bushing, and the upper end is fixedly connected to the top of the frame by an L-shaped washer and an adjusting bolt.

[0013] Furthermore, the second elastic element is a rubber limiting block.

[0014] Furthermore, a failure protection device facing downwards is fixed to the top of the frame.

[0015] Furthermore, the failure protection device includes a limiting post, the upper end of which is connected to the top of the frame, and the lower end of which is provided with a collision head. The collision head is located above the floating plate and there is a gap between the collision head and the floating plate. The collision head has an inverted conical structure.

[0016] The beneficial effects of this utility model are:

[0017] This utility model connects the vehicle frame and wheels by setting up a frame, a traveling mechanism fixing frame, a traveling mechanism, and a slewing device. By setting guide rods, a first elastic element, and a second elastic element within the frame to integrate a shock absorption device, it plays a certain role in damping the floating process of the traveling mechanism fixing frame and the connected wheel hub. At the same time, the tension of the first elastic element can be adjusted arbitrarily. This integrated half-bridge structure not only solves the problem of integrating slewing operation and shock absorption in mining vehicles, but also saves a considerable amount of space and weight. It is very suitable for the use of special operation vehicle traveling mechanisms under extreme size conditions. All mechanisms can be hidden behind the tires, and the pipeline and wiring layout will not be exposed. It is specifically designed for mining vehicles and can adapt to various complex working conditions. Attached Figure Description

[0025] Example 1

[0026] This utility model provides a half-axle structure for mining vehicles, connecting the frame and wheels of the mining vehicle. The half-axle structure for mining vehicles includes:

[0027] Frame 9, with two vertically arranged guide rods 8 fixed inside the frame 9, and the top of the frame 9 connected to the vehicle frame through a slewing mechanism 1; a failure protection device 4 facing downward is fixed to the top of the frame 9;

[0028] The traveling mechanism fixing frame includes two bushings 5 ​​sleeved on two guide rods 8 and a floating plate 10 connecting the two bushings 5. The floating plate 10 is connected to the wheel hub through the traveling mechanism 6. Both bushings 5 ​​are fixed to the frame 9. The frame 9 is a vertically arranged rectangular frame. The floating plate 10 is an annular plate, and the traveling mechanism 6 connecting the wheel hub is assembled inside the floating plate 10.

[0029] The first elastic element 3 connects the upper end of the bushing 5 and the top of the frame 9, and the first elastic element 3 is sleeved on the guide rod 8;

[0030] The second elastic element 11 connects the lower end of the bushing 5 and the bottom of the frame 9.

[0031] Furthermore, the walking mechanism is a wheel-side motor, which is a three-in-one device integrating running, service braking and parking braking.

[0032] Furthermore, the first elastic element 3 is a spring. The lower end of the spring is compressed and fixed to the top of the bushing 5, and the upper end is fixedly connected to the top of the frame 9 through an L-shaped washer 2 and an adjusting bolt 12. The first elastic element 3 can play a certain role in limiting and damping the upper part of the bushing 5. Rotating the adjusting bolt 12 can adjust the tension of the spring. The second elastic element 11 is a rubber limiting block with a certain elasticity, which can play a certain role in limiting and damping the lower part of the bushing 5.

[0033] Preferably, the failure protection device 4 includes a limiting post, the upper end of which is connected to the top of the frame 9, and the lower end of which is provided with a collision head. The collision head is located above the floating plate 10 and there is a gap between the collision head and the floating plate 10. The collision head has an inverted conical structure.

[0034] When running on bumpy roads, the fixed frame of the traveling mechanism will float up and down within the frame 9, and the wheels 7 will also vibrate up and down with the floating plate 10. Due to the limiting effect of the first elastic element 3 and the second elastic element 11 and their own elasticity, this vibration will be attenuated to a certain extent, thus playing a shock absorption role. At the same time, the slewing mechanism 1 connected to the top of the frame 9 and the traveling mechanism 6 connected to the floating plate 10 can both work normally.

[0035] When the first elastic element 3 fails, the bushing 5 will lose its downward elastic pressure and will rise upward during vibration. Since the present invention is equipped with a failure protection device 4, namely a limiting post, it can effectively block the collision head and limit the upward displacement of the bushing 5, thereby playing a protective role.

[0036] In addition, this utility model can also be combined with the frame in different ways to form a variety of walking modes, such as the currently mainstream crab walking mode, bending mode, and stationary turning mode, to adapt to various complex working conditions.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
