Description

Technical Field

[0001] This utility model relates to the field of bucket wheel excavator technology, specifically a bucket wheel excavator support device. Background Technology

[0002] A bucket wheel stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards, capable of both stacking and reclaiming materials. It consists of a belt conveyor arm capable of tilting and swinging horizontally, a bucket wheel at its front end, a frame, and a running mechanism. The belt can run in both directions. During reclaiming, material is picked up by the bucket wheel and conveyed out through the conveyor arm; during stacking, goods transported by the main conveyor are thrown into the yard via the conveyor arm. It has two operating modes: stacking and reclaiming. For stacking, bulk materials transported by the belt conveyor are unloaded onto the belt conveyor on the boom via a tail car, and then dumped from the front end of the boom into the yard. Through the operation of the entire machine, the rotation and tilting of the boom can form a neat trapezoidal cross-section shape in the stockpile. Reclaiming is achieved continuously through the rotation of the boom and the rotation of the bucket wheel. The material is unloaded via a discharge plate onto the counter-clockwise running belt conveyor on the boom, and then discharged through a hopper at the center of the machine to the yard belt conveyor for transport away. Through the operation of the whole machine, the boom can rotate and tilt, allowing the bucket wheel to remove all the material from the storage pile. However, the shaft of the bucket wheel at the front end of the bucket wheel machine is mostly a fixed structure, and the height cannot be adjusted. When removing material, it is mostly achieved by adjusting the boom. However, it is difficult to make small vertical adjustments through boom operation, thus making it difficult to make the bucket wheel remove material effectively. Utility Model Content

The inflation volume of each second bladder can be controlled independently, and the second bladders in different positions can be fine-tuned as needed to correct minor offsets or tilts of the equipment. This fine-tuning function is crucial for ensuring precise alignment and efficient operation of the bucket wheel excavator during operation. The design of the second bladders allows the bucket wheel excavator to better adapt to these changes. By adjusting the inflation volume of the second bladders, it can be ensured that the equipment maintains a stable support state under various working conditions. Attached Figure Description

[0046] The fixing component 100 includes a housing 110, a hydraulic cylinder 120, a fixing block 130, and an L-shaped connecting block 140;

[0047] The housing 110 is a rectangular body, and its installation direction is perpendicular to the ground. The top of the housing 110 is provided with an installation groove 111.

[0048] The mounting groove 111 is a rectangular groove, and a hydraulic cylinder 120 is fixedly connected in the mounting groove 111;

[0049] There are two hydraulic cylinders 120, and a fixing block 130 is fixedly connected to the top of each hydraulic cylinder 120.

[0050] The fixing block 130 is ellipsoidal in shape, and the top center of the fixing block 130 is fixedly connected to the lower end of the L-shaped connecting block 140;

[0051] The L-shaped connecting block 140 has a circular cross-section, and one end of the L-shaped connecting block 140 is fixedly connected to the top of the fixing block 130;

[0052] The upper end of the L-shaped connecting block 140 is fixedly connected to the outer side of the connecting plate 310;

[0053] The connecting component 300 includes a connecting disk 310, a connecting groove 320, and a protrusion 330;

[0054] The connecting plate 310 is cylindrical, and a rotating shaft connecting groove 320 is provided at the center of the inner side of the connecting plate 310.

[0055] The connecting groove 320 is cylindrical, and a protrusion 330 is fixedly connected inside the connecting groove 320;

[0056] There are at least four protrusions 330, each protrusion 330 is an arc-shaped body, and the protrusions 330 are fixedly connected at equal intervals inside the rotating shaft connecting groove 320;

[0057] The bottom of the connecting plate 310 is fixedly connected to an elastic component 400;

[0058] The elastic component 400 includes a first bladder 410;

[0059] The first bladder 410 is an arched body, and a through mounting hole is provided in the middle of the first bladder 410. The mounting hole is rectangular.

[0060] The support assembly 200 includes a support frame 210, a mounting plate 220, bolt holes 230, a connecting seat 240, a cylinder 250, and a support base 260;

[0061] The support frame 210 is a rectangular body, and the support frame 210 is disposed on one side of the housing 110. Connecting seats 240 are installed on both sides of the upper end of the support frame 210.

[0062] One end of each of the two cylinders 250 is rotatably connected to one of the two connecting seats 240;

[0063] Support seats 260 are installed at the ends of the output shafts of both cylinders 250;

[0064] The two support bases 260 are respectively rotatably connected to the outer sides of the connecting plate 310;

[0065] One end of the support frame 210 is fixedly connected to a mounting plate 220, which is a square prism.

[0066] The mounting plate 220 has at least four bolt holes 230;

[0067] The bolt hole 230 is a circular through hole;

[0068] Multiple tension bars 211 are installed at equal intervals inside the support frame 210.

[0069] In practical use, after the first chamber 410 is inflated, the internal air pressure can provide a certain supporting force. When the bucket wheel excavator vibrates or is impacted during operation, the first chamber 410 can absorb and disperse these forces, thereby reducing the direct impact on other structural components. When the gas in the first chamber 410 reaches saturation, the ground of the first chamber 410 will be supported on the support frame 210, which can better distribute the force from the bucket wheel excavator and extend the service life of the equipment. The elasticity of the first chamber 410 allows it to adaptively adjust to a certain extent according to the load and vibration of the bucket wheel excavator. When the load increases or the vibration intensifies, the first chamber 410 can be further inflated to provide more supporting force. Conversely, when the load decreases or the vibration weakens, the gas in the first chamber 410 can also be appropriately discharged to maintain the best supporting state. Through the buffering effect of the first chamber 410, the noise and vibration generated by the bucket wheel excavator during operation can be effectively reduced.

[0070] Example 2: The elastic component 400 further includes a second bladder 420;

[0071] The second sac 420 is an arched body. There are multiple second sacs 420, and the sacs are not interconnected. The second sac 420 is fixedly connected to the bottom of the first sac 410.

[0072] In the elastic component 400 of the bucket wheel excavator support device, the second bladder 420 is fixedly connected to the bottom of the first bladder 410 to increase the overall structural stability and the ability to fine-tune the angle. The second bladder 420 is tightly connected to the first bladder 410 to ensure a stable connection during inflation and deflation. The presence of the second bladder 420 can further disperse and buffer the vibration and impact forces generated during the operation of the bucket wheel excavator. Due to the large number and even distribution of the second bladders 420, they can work together or independently to provide a more uniform and stable support force, thereby reducing cylinder swaying and instability. The second bladders 420 have independent inflation and deflation functions. The air pressure of each second bladder 420 can be adjusted as needed to fine-tune the angle and height of the support device. This fine-tuning function helps optimize the working posture of the bucket wheel excavator and improves operating efficiency and accuracy.
