Description

Technical Field

[0001] This utility model relates to the technical field of shock absorption, and in particular to a shock absorption suspension device for a wheel loader cab. Background Technology

[0002] Wheel loaders are earthmoving machines widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. They are mainly used for loading and unloading bulk materials such as soil, sand, gravel, lime, and coal, and can also perform light digging operations on ores and hard soil. Because wheel loaders often operate on uneven ground, they experience significant vibrations, necessitating the installation of shock-absorbing devices in the cab to reduce vibration. In the prior art, a utility model patent with patent application number 202422186538.8 discloses a loader cab shock absorption device, which mainly consists of a frame, springs, and dampers. The cab is mounted on the frame via springs and dampers, and its use involves reducing the weight of the cab through the springs and dampers. However, it has the following problems during use: when the wheel loader operates on uneven terrain, slopes, or in mining or construction sites, the ground conditions are poor and the ground is uneven, causing the loader to tilt during movement, which leads to a shift in the center of gravity and a risk of overturning. The device in the prior art only has a shock absorption function and does not have an anti-overturning function, which limits its use and is inconvenient. Therefore, a loader cab shock absorption device with an anti-overturning function is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a wheel loader cab shock absorption suspension device that not only has the function of shock absorption, but also the function of adjusting the vehicle's center of gravity, reducing the risk of vehicle rollover, and is easy to use, safe and reliable.

[0004] This utility model discloses a shock-absorbing suspension device for a wheel loader cab, comprising a frame, multiple spring-damped shock absorbers, and a support plate. The multiple spring-damped shock absorbers are fixedly mounted on the upper end of the frame, and the support plate is fixedly mounted on the upper end of the multiple spring-damped shock absorbers. It also includes a center-of-gravity adjustment mechanism mounted on the frame, which has the function of adjusting the center of gravity. The frame is mounted on the wheel-running mechanism of the wheel loader, and the cab is mounted on the upper end of the support plate. When the loader is traveling on the road, the spring-damped shock absorbers reduce the vibration of the support plate and the cab, while the center-of-gravity adjustment mechanism adjusts the vehicle's center of gravity in real time, keeping the vehicle balanced and reducing the risk of rollover. It is convenient to use and offers high safety and reliability.

[0005] Preferably, the center of gravity adjustment mechanism includes a moving mechanism, a counterweight, a level, and a controller. The counterweight is mounted on the frame via the moving mechanism, which moves the counterweight back and forth. The level is mounted on the frame and is used to detect the levelness of the frame in the front-to-back direction. The controller is mounted on the frame and is connected to the moving mechanism and the level. When the vehicle is in motion, the level detects the vehicle's balance and transmits the vehicle's tilt to the controller. The controller then moves the counterweight accordingly based on the transmitted data, thereby adjusting the vehicle's center of gravity and reducing the risk of vehicle rollover.

[0006] Preferably, the moving mechanism includes a linear module and a sliding plate. The linear module is mounted on the vehicle frame, and the sliding plate is provided on the linear module. The linear module is used to move the sliding plate back and forth. A counterweight is fixedly mounted on the upper end of the sliding plate. The linear module is connected to a controller. When the position of the counterweight is adjusted, the controller controls the linear module to move the sliding plate in the back and forth direction, thereby moving the counterweight in the back and forth direction, adjusting the vehicle's center of gravity until the vehicle is balanced.

[0007] Preferably, it also includes a crash barrier and a flexible mechanism, with the crash barrier installed on the right end of the frame via the flexible mechanism; with the above configuration, when the frame collides with the outside world, the object in the outside world will collide with the crash barrier first, reducing the risk of the frame colliding with the outside world.

[0008] Preferably, the flexible mechanism includes a fixed column, a sliding column, and a spring. The fixed column is fixedly installed on the vehicle frame, the sliding column is slidably installed on the fixed column, the left end of the spring is fixedly installed on the vehicle frame, and the anti-collision plate is fixedly installed on the right end of the sliding column and the spring. When the right end of the vehicle frame collides with the outside, the object first contacts the anti-collision plate, and then the spring is compressed, which slows down the speed of the object when it collides with the vehicle frame, reduces the instantaneous impulse during the collision, and improves safety.

[0009] Preferably, rubber plates are provided at both the front and rear ends of the frame; this arrangement reduces external impacts on the front and rear ends of the frame.

[0010] Preferably, the rubber plate is provided with multiple reflective strips; this arrangement improves the visibility of the vehicle frame and alerts nearby people to avoid it.

[0011] Compared with the prior art, the advantages of this utility model are: it not only has the function of shock absorption, but also the function of adjusting the center of gravity of the vehicle, reducing the risk of vehicle rollover, and is convenient to use, with high safety and reliability.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0020] like Figures 1 to 6 The shock-absorbing suspension device for the cab of a wheel loader of this utility model includes a frame 1, multiple spring-damped shock absorbers 2, a support plate 3, and a center of gravity adjustment mechanism. The multiple spring-damped shock absorbers 2 are all fixedly installed on the upper end of the frame 1, and the support plate 3 is fixedly installed on the upper end of the multiple spring-damped shock absorbers 2. The center of gravity adjustment mechanism is installed on the frame 1 and has the function of adjusting the center of gravity. The frame 1 is installed on the wheel running mechanism of the wheel loader, and the cab is installed on the upper end of the support plate 3. When the loader is traveling on the road, the spring-damped shock absorbers 2 reduce the vibration of the support plate 3, thereby reducing the vibration of the cab. Furthermore, the center of gravity adjustment mechanism adjusts the vehicle's center of gravity in real time, keeping the vehicle balanced, reducing the risk of vehicle overturning, and is convenient to use with high safety and reliability.

[0021] like Figure 1 , Figure 3 and Figure 4The center of gravity adjustment mechanism includes a moving mechanism, a counterweight 4, a level 5, and a controller 6. The counterweight 4 is mounted on the frame 1 via the moving mechanism, which is used to move the counterweight 4 back and forth. The level 5 is mounted on the frame 1 and is used to detect the levelness of the frame 1 in the front and rear directions. The controller 6 is mounted on the frame 1 and is connected to the moving mechanism and the level 5. When the vehicle is in motion, the level 5 detects the balance of the vehicle and transmits the vehicle's tilt to the controller 6. The controller 6, based on the transmitted data, causes the moving mechanism to move the counterweight 4 accordingly, thereby adjusting the vehicle's center of gravity and reducing the risk of vehicle rollover.

[0022] like Figure 4 The moving mechanism includes a linear module 7 and a sliding plate 8. The linear module 7 is mounted on the frame 1, and the sliding plate 8 is provided on the linear module 7. The linear module 7 is used to move the sliding plate 8 back and forth. The counterweight 4 is fixedly mounted on the upper end of the sliding plate 8. The linear module 7 is connected to the controller 6. When the position of the counterweight 4 is adjusted, the controller 6 controls the linear module 7, so that the linear module 7 drives the sliding plate 8 to move in the back and forth direction, thereby driving the counterweight 4 to move in the back and forth direction, adjusting the center of gravity of the vehicle until the vehicle is balanced.

[0023] like Figure 3 and Figure 5 It also includes a crash barrier 9 and a flexible mechanism. The crash barrier 9 is installed on the right end of the frame 1 through the flexible mechanism. With the above settings, when the frame 1 collides with the outside world, the object in the outside world will first collide with the crash barrier 9, reducing the risk of the frame 1 colliding with the outside world.

[0024] like Figure 5 The flexible mechanism includes a fixed column 10, a sliding column 11, and a spring 12. The fixed column 10 is fixedly installed on the frame 1, and the sliding column 11 is slidably installed on the fixed column 10. The left end of the spring 12 is fixedly installed on the frame 1, and the anti-collision plate 9 is fixedly installed on the right end of the sliding column 11 and the spring 12. When the right end of the frame 1 collides with the outside, the object first contacts the anti-collision plate 9, and then the spring 12 is compressed, which slows down the speed of the object when it collides with the frame 1, reduces the instantaneous impulse during the collision, and improves safety. Example 2

[0025] Based on Embodiment 1, rubber plates 13 are provided at both the front and rear ends of the frame 1; through the above-mentioned arrangement, the impact of external forces on the front and rear ends of the frame 1 is reduced.

[0026] Multiple reflective strips 14 are provided on the rubber plate 13; through the above-mentioned arrangement, the visibility of the frame 1 is improved, and people nearby are reminded to pay attention and avoid it.

[0027] The spring-damped shock absorber 2, level 5, controller 6, rubber plate 13, and reflective strip 14 of the shock-absorbing suspension device for the wheel loader cab of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0028] The above description is only a preferred embodiment of the present utility model.
