Description

Technical Field

[0001] This invention relates to a life evaluation system and method for spectacle plate cutting rings, belonging to the technical field of life testing and evaluation of vulnerable parts. Background Technology

[0002] The spectacle plate cutting ring is an essential component in the concrete pumping process. During pumping, the cutting ring reciprocates by swinging left and right with the S-shaped oscillating pipe, cutting the concrete continuously conveyed in the conveying cylinder in a changing direction. As the feeding and conveying alternate between the two conveying holes, frequent impacts occur between the spectacle plate and the cutting ring and the concrete material.

[0003] Prolonged cutting and impact require spectacle plate cutting rings to possess high wear resistance, as well as excellent impact resistance, crack resistance, and fatigue resistance. These vulnerable parts operate under complex conditions with inconsistent concrete batches, making it difficult to effectively assess their process reliability through on-machine life verification. Furthermore, on-machine verification is time-consuming and lacks traceability. Therefore, controlling uniform operating conditions for spectacle plate cutting ring performance evaluation testing presents a significant challenge.

[0004] Currently, there are very few publicly available reports in China regarding devices for evaluating the service life of spectacle plate cutting rings. The vast majority of publicly available information focuses on new structures and manufacturing methods for spectacle plate cutting rings. Only a few reports concern pumping devices for spectacle plates and cutting rings in hoppers, specifically novel hopper layouts for pump trucks. Current methods for evaluating the service life of spectacle plate cutting rings primarily rely on small-scale wet sand abrasion tests. These tests involve cutting and sampling the spectacle plate cutting ring to be evaluated, placing the sample in a testing machine for load-bearing abrasion testing, and the test results directly reflect the material's wear resistance. Whole-piece testing of spectacle plate cutting rings mainly involves installation verification.

[0005] Life assessments of wear-resistant consumable parts like spectacle plate cutting rings, whether self-developed or externally procured, currently only involve wet sand abrasion testing and bond strength analysis after cutting, testing only the material's intrinsic wear resistance and bond strength. Furthermore, life assessments using installed equipment are time-consuming, provide slow data feedback, delay development cycles, and hinder effective process improvement. Most publicly available materials still rely on laboratory-scale segmented cutting for routine testing, resulting in poor compatibility with actual operating conditions. Summary of the Invention

In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0043] This embodiment discloses a life evaluation system for spectacle plate cutting rings, such as... Figure 1 , Figure 2 , Figure 3As shown, it includes an upper pumping system, a lower pumping system, and accessories. Specifically, the upper pumping system includes an upper left hydraulic cylinder 1, an upper right hydraulic cylinder 2, an upper water tank 3, an upper left conveying cylinder 4, an upper right conveying cylinder 5, an upper spectacle plate 6, an upper cutting ring 7, and an upper S-shaped swing pipe 8; the lower pumping system includes a lower left hydraulic cylinder 9, a lower right hydraulic cylinder 10, a lower water tank 11, a lower left conveying cylinder 12, a lower right conveying cylinder 13, a lower spectacle plate 14, a lower cutting ring 15, and a lower S-shaped swing pipe 16; the accessories include an upper hopper, an lower hopper, and a conveying pipe.

[0044] The upper and lower pumping systems are bolted to the support frame and powered by hydraulic pressure.

[0045] The telescopic ends of the upper left hydraulic cylinder 1 and the upper right hydraulic cylinder 2 are respectively connected to one side of the upper water tank 3. The other side of the upper water tank 3 is connected to the upper left conveying cylinder 4 and the upper right conveying cylinder 5. The upper left hydraulic cylinder 1 and the upper left conveying cylinder 4 are coaxially arranged, and the upper right hydraulic cylinder 2 and the upper right conveying cylinder 5 are also coaxially arranged. The piston head of the telescopic end of the upper left hydraulic cylinder 1 can reciprocate within the upper left conveying cylinder 4, and the piston head of the telescopic end of the upper right hydraulic cylinder 2 can reciprocate within the upper right conveying cylinder 5. The outlets of the upper left conveying cylinder 4 and the upper right conveying cylinder 5 are respectively connected to the feeding hopper.

[0046] The front end of the upper S-shaped sway tube 8 is connected to the upper cutting ring 7, and the rear end of the upper S-shaped sway tube 8 is used to connect to the conveying pipe. The upper cutting ring 7 is attached to the upper spectacle plate 6 located on the hopper. The two inlet holes of the upper spectacle plate 6 correspond to the outlet of the upper left conveying cylinder 4 and the outlet of the upper right conveying cylinder 5, respectively. The upper S-shaped sway tube 8 is located inside the hopper. In actual use, the upper S-shaped sway tube 8 is connected to the upper left conveying cylinder 4, and the upper left hydraulic cylinder 1 starts to suck up the concrete in the conveying pipe into the upper left conveying cylinder 4. After the suction is completed, the upper S-shaped sway tube 8 is connected to the outlet of the upper right hydraulic cylinder 2 to suck up the concrete. At this time, the upper left hydraulic cylinder 1 starts to push the concrete into the hopper. After the upper left hydraulic cylinder 1 finishes pushing, the upper right hydraulic cylinder 2 also finishes sucking up the concrete. The upper S-shaped sway tube 8 is reconnected to the outlet of the upper left hydraulic cylinder 1 to start sucking up the concrete, while the upper right hydraulic cylinder 2 starts pushing, and the suction and pushing cycle is repeated.

[0047] The telescopic ends of the lower left hydraulic cylinder 9 and the lower right hydraulic cylinder 10 are respectively connected to one side of the lower water tank 11. The other side of the lower water tank 11 is connected to the lower left conveying cylinder 12 and the lower right conveying cylinder 13. The lower left hydraulic cylinder 9 and the lower left conveying cylinder 12 are coaxially arranged, as are the lower right hydraulic cylinder 10 and the lower right conveying cylinder 13.

The outlets of the lower left conveying cylinder 12 and the lower right conveying cylinder 13 are respectively connected to the feeding hopper.

[0048] The front end of the lower S-shaped swing tube 16 is connected to the lower cutting ring 15, and the rear end of the lower S-shaped swing tube 16 is used to connect to the conveying pipe. The other end of the conveying pipe is connected to the upper hopper. The lower cutting ring 15 is fitted with the lower spectacle plate 14 located on the lower hopper. The two inlet holes of the lower spectacle plate 14 correspond to the outlet of the lower left conveying cylinder 12 and the outlet of the lower right conveying cylinder 13, respectively. The lower S-shaped swing pipe 16 is located inside the discharge hopper. In actual use, concrete enters the discharge hopper from the upper hopper. The lower left hydraulic cylinder 9 drives the lower left conveying cylinder 12 to start sucking material from the discharge hopper. After the material is sucked, the lower S-shaped swing pipe 16 connects with the outlet of the lower left hydraulic cylinder 9, and the lower left hydraulic cylinder 9 starts to push the concrete. On the other side, the lower right hydraulic cylinder 10 drives the lower right conveying cylinder 13 to start sucking material. When the pushing lower left hydraulic cylinder 9 finishes pushing, the sucking lower right hydraulic cylinder 10 finishes sucking material. The lower S-shaped swing pipe 16 connects with the outlet of the lower right conveying cylinder 13, which is full of material, and pushes it. The lower left hydraulic cylinder 9 starts to suck material, and the cycle of sucking and pushing is repeated to complete the pushing of concrete.

[0049] In this embodiment, each hydraulic cylinder provides variable active and passive pressure to push or pull the piston head in the conveying cylinder; each water tank is used to clean the piston head reciprocating in each conveying cylinder, keeping the piston head clean; the piston head is used to push the concrete in the conveying cylinder; each conveying cylinder is used to temporarily store the sucked-in concrete material. The conveying cylinder of the upper pumping system sucks in concrete and pushes the concrete in the cylinder to the upper hopper in the next reversing cycle, and the conveying cylinder of the lower pumping system sucks in concrete from the lower hopper and pushes the concrete in the cylinder to the conveying pipe through the lower S-shaped swing pipe in the next reversing cycle; spectacle plate and cutting ring are... The upper hopper is fixed to the hopper and the S-shaped swing pipe. During the reversing process of the S-shaped swing pipe, it is used to cut off the flow of concrete material between the conveying cylinder and the swing pipe. The upper hopper is used to hold the concrete material pushed out from the conveying cylinder and automatically drops from the discharge port to the lower hopper. Both the upper and lower hoppers are equipped with a mixing device to prevent the concrete material from segregating or solidifying. The conveying pipe is used to connect the upper and lower S-shaped swing pipes and transport the concrete material from the lower conveying cylinder until it reaches the conveying bar corresponding to the upper S-shaped swing pipe. The lower S-shaped swing pipe alternately connects to the lower left conveying cylinder 12 and the lower right conveying cylinder 13 for conveying the concrete material in the cylinder.

[0050] The working method of the spectacle plate cutting ring life evaluation system is as follows:

[0051] The first step is to place the concrete material into the hopper and turn on the mixing system;

[0052] In the second step, the lower left hydraulic cylinder 9 is at the top, close to the lower water tank 11, and the lower left conveying cylinder 12 is connected to the feeding hopper. The lower right hydraulic cylinder 10 retracts to the bottom of the cylinder, away from the lower water tank 11, and the lower S-shaped swing tube 16 is tightly connected to the lower right conveying cylinder 13 through the lower cutting ring 15;

[0053] Third step, the upper left oil cylinder 1 retracts to the bottom of the oil cylinder, away from the upper water tank 3, and connects to the feeding hopper; the upper right oil cylinder 2 is at the top, close to the upper water tank 3, and the upper S swing tube 8 is tightly connected to the upper right conveying cylinder 5 through the upper cutting ring 7.

[0054] Step 4: Set the push-out pressure of the lower left hydraulic cylinder 9 and the lower right hydraulic cylinder 10 to 1-30 MPa and the pull-back pressure to 1-5 MPa; set the push-out pressure of the upper left hydraulic cylinder 1 and the upper right hydraulic cylinder 2 to 1-5 MPa and the back pressure to 5-10 MPa (passive retraction); set the swing frequency of the upper S-swing tube 8 and the lower S-swing tube 16 to 10-45 times / min, the same frequency as the reciprocating motion of the hydraulic cylinders; set the number of cuts to 100,000-500,000 times.

[0055] Fifth step: Activate the evaluation system, and all four cylinders begin operating simultaneously. In the first cycle, the lower left cylinder 9 retracts, pulling the piston head to draw concrete material from the hopper into the lower left conveying cylinder 12, while the upper left cylinder 1 extends, discharging the concrete from the upper left conveying cylinder 4 into the hopper. Simultaneously, the lower right cylinder 10 pushes the piston head, conveying the concrete material from the lower right conveying cylinder 13 through the S-swing pipe 16 and the conveying pipe to the upper S-swing pipe 8, further conveying it to the upper right conveying cylinder 5, while the upper right cylinder 2 retracts under pressure.

[0056] Step 6: Under the action of the swing valve, the upper S-swing pipe 8 and the lower S-swing pipe 16 switch directions to the upper left conveying cylinder 4 and the lower left conveying cylinder 12, and start the next cycle of pumping.

[0057] Step 7: Based on the established evaluation plan, inspect the wear appearance and weight loss of the upper spectacle plate 6, upper cutting ring 7, lower spectacle plate 14, and lower cutting ring 15, and record the failure information.

[0058] Step 8: After the life evaluation test is completed, the evaluation system is shut down, and the failure modes and life evaluation of the spectacle plate cutting ring are analyzed.

[0059] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
