For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.
[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a hydraulically driven heavy machinery brake, comprising:
[0032] The heavy-duty mechanical brake housing 1 is equipped with a braking mechanism. It should be noted that when the brake pads 8 need maintenance or replacement, the brake pads 8 can be maintained or replaced quickly, and the operation is relatively convenient.
[0033] The braking mechanism includes a connector 7, a brake pad 8, a support 9, a sliding member 10, a first docking block 12, a second docking block 13, an integral block 14, and a T-block 16. It should be noted that the connector 7, support 9, sliding member 10, first docking block 12, second docking block 13, integral block 14, and T-block 16 are all made of alloy steel, which has high strength and can be used for a long time to ensure stable operation.
[0034] Brake pad 8 is fixedly connected to docking block 12, docking block 12 is fixedly connected to docking block 23, docking block 12 and docking block 23 are both engaged with connector 7, support 9 is fixedly connected to the side of heavy machinery brake housing 1, sliding member 10 is slidably sleeved on the outside of support 9, sliding member 10 is fixedly connected to connector 7, integral block 14 is fixedly connected to support 9, and T-shaped block 16 is fixedly connected to docking block 23.
[0035] Through the above structure Figures 1-5 The T-block 16 is aligned with the T-hole 15 on the integral block 14, but it is not yet engaged. When assembling the brake pad 8, firstly, engage the first docking block 12 and the second docking block 13 into the adapter groove 11. Then, start the gear pump 3 to move the piston 5, which in turn moves the connecting part 7. This allows the second docking block 13 to drive the T-block 16 to be fully engaged into the T-hole 15. At this time, there is still a small distance between the brake pad 8 and the rotating structure of the heavy machinery. This completes the quick assembly of the brake pad 8. Subsequently, hydraulic oil is added through the gear pump 3. The brake pad 8 continues to move to brake the rotating structure of the heavy machinery. The movement distance is relatively short. At this time, the T-block 16 is still completely within the T-hole 15. Moreover, when maintenance or replacement is required, the brake pad 8 can be quickly removed, making the operation convenient.
[0036] Specifically, the braking mechanism also includes an oil tank 2, a gear pump 3, a hydraulic oil chamber 4, a piston 5, and a steel rod 6. The oil tank 2 is fixedly installed on the top of the heavy machinery brake housing 1, the gear pump 3 is fixedly installed on the top of the heavy machinery brake housing 1, the hydraulic oil chamber 4 is opened inside the heavy machinery brake housing 1, the piston 5 is slidably sealed inside the hydraulic oil chamber 4, and the steel rod 6 is fixedly installed between the piston 5 and the connecting member 7.
[0037] With the above structure, when the gear pump 3 starts, it can draw hydraulic oil into the hydraulic oil chamber 4, causing the hydraulic oil to push the piston 5 to move, which in turn causes the two brake pads 8 to move, thus braking the heavy machinery. The heavy machinery brake housing 1 is fixedly installed at the designated position on the heavy machinery by welding. When maintenance or replacement is required, a set amount of hydraulic oil is drawn out to ensure that the brake is in the final position. Figures 1-5 The desired state is that during normal use, excessive hydraulic oil will not be drawn out, ensuring that the T-block 16 is always completely within the T-hole 15.
[0038] Specifically, the connector 7 has an adapter groove 11 on its front side. Both the first docking block 12 and the second docking block 13 are engaged with the adapter groove 11. It should be noted that the rear sides of the first docking block 12 and the second docking block 13 abut against the rear inner wall of the adapter groove 11, which can limit the positioning of the first docking block 12 and the second docking block 13.
[0039] Specifically, a T-shaped hole 15 is provided on the side of the integral block 14, and a T-shaped block 16 is located on one side of the T-shaped hole 15. The second docking block 13 is in contact with the integral block 14. It should be noted that the T-shaped block 16 can be inserted into the T-shaped hole 15, so as to limit the positioning of the first docking block 12 and the second docking block 13.
[0040] Specifically, the brake pad 8 contacts the inner side of the connector 7. It should be noted that the position of the brake pad 8 is limited.
[0041] Specifically, the gear pump 3 has an oil pipe 1 fixedly installed on the top, which is fixedly mounted on the oil tank 2 and extends into the interior of the oil tank 2. The gear pump 3 has an oil pipe 2 fixedly installed on the bottom, which is fixedly mounted on the heavy machinery brake housing 1 and extends into the interior of the hydraulic oil chamber 4. It should be noted that the gear pump 3 is connected to an external PLC controller. By setting a program in advance, the gear pump 3 can be adjusted and processed, so that the brake pad 8 can be accurately moved to the set designated position for braking.
[0042] Working principle:
[0043] S1: Before assembly, the T-block 16 and the T-hole 15 on the integral block 14 are aligned but not engaged. First, the first docking block 12 and the second docking block 13 connected to the brake pad 8 are aligned with the adapter groove 11 on the front side of the connector 7 and engaged. The brake pad 8 contacts the inner side of the connector 7 to achieve initial positioning. The gear pump 3 is started, and hydraulic oil is drawn from the oil tank 2 through the first oil pipe and injected into the hydraulic oil chamber 4 through the second oil pipe. The hydraulic oil pushes the piston 5 to slide along the hydraulic oil chamber 4. The piston 5 drives the connector 7 to move synchronously through the steel rod 6. The sliding part 10 slides along the support part 9 to provide guidance for the connector 7. When the connector 7 moves, it drives the second docking block 13 to move synchronously, so that the T-block 16 is fully engaged in the T-hole 15, completing the rapid fixing of the brake pad 8. At this time, the brake pad 8 maintains a small gap with the rotating structure of the heavy machinery, which not only ensures that the assembly is in place, but also reserves stroke for subsequent braking. The engaging structure of the T-block 16 and the T-hole 15 can prevent the brake pad 8 from loosening.
[0044] S2: During braking, the gear pump 3 continuously injects hydraulic oil into the hydraulic oil chamber 4 through the external PLC controller. The hydraulic oil pushes the piston 5 to continue moving, and through the steel rod 6 and the connecting piece 7, it drives the brake pad 8 to approach the rotating structure of the heavy machinery. Since the brake pad 8 only needs to move a short stroke to contact the rotating structure, the T-block 16 is always completely inside the T-hole 15 during this process, ensuring the stability of the brake pad 8. After the brake pad 8 contacts the rotating structure, the friction force is used to decelerate or stop the heavy machinery. The cooperation between the support piece 9 and the sliding piece 10 ensures that the movement trajectory of the brake pad 8 is accurate and avoids uneven wear that affects the braking effect.
[0045] S3: When the brake pad 8 is worn and needs maintenance or replacement, the gear pump 3 is controlled by the PLC controller to work in reverse, extracting a set amount of hydraulic oil from the hydraulic oil chamber 4. The piston 5 drives the connecting piece 7 to move in reverse until the T-block 16 and the T-hole 15 are aligned but not locked in the initial state. At this time, the locking constraint between the first docking block 12 and the second docking block 13 and the adapter groove 11 is released, and the brake pad 8 can be pulled out directly. The first docking block 12, the second docking block 13 and the T-block 16 can be taken out together without disassembling multiple bolts. This is suitable for scenarios with limited assembly space. After replacing the new brake pad 8, the operation is repeated according to the assembly process to quickly complete the reset and restore the braking function.
[0046] The present invention provides a detailed description of a hydraulically driven heavy machinery brake. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
