Description

Technical Field

[0001] This utility model relates to the field of eyeplate technology, specifically to a corrosion-resistant eyeplate structure. Background Technology

[0002] The eye plate is an important wear-resistant component of a concrete pump, usually used in conjunction with the cutting ring. It needs to withstand the wear and erosion caused by the high strength and high viscosity of concrete. Therefore, it is made of hard alloy material, which has extremely high hardness, strength, and excellent wear resistance and corrosion resistance.

[0003] In concrete pumping equipment, spectacle plates typically have two circular holes. The inner circular parts of these holes are prone to wear due to long-term contact with high-pressure concrete. Currently, most spectacle plates on the market adopt an integrated structure. Once local wear occurs, the entire plate needs to be replaced, which undoubtedly results in a significant waste of resources.

[0004] To address this issue, an improved solution has been proposed in the prior art: a through mounting hole is made in the spectacle plate, and a wear-prone curved plate is fixed to the spectacle plate with bolts. This way, when the curved plate wears out, only the curved plate needs to be replaced, instead of the entire spectacle plate, thus reducing operating costs. However, this design also presents some potential problems. If the fit between the bolts and the mounting hole is not tight enough, or if the sealing measures are inadequate, concrete can leak from these gaps. Especially during high-pressure pumping, the high pressure of the concrete further increases the risk of leakage. Once the concrete leaks into the mounting hole and solidifies, it will greatly hinder subsequent disassembly work, affecting the efficiency of equipment maintenance and replacement. Therefore, a corrosion-resistant spectacle plate structure is proposed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant eyeplate structure to solve the problem that if the bolts and mounting holes are not tightly fitted or the sealing measures are inadequate when through mounting holes are made on the eyeplate, concrete will leak from these gaps. Especially during high-pressure pumping, the pressure of the concrete is high, which further increases the risk of leakage. Once the concrete leaks into the mounting hole and solidifies, it will bring great difficulties to the subsequent disassembly work and affect the maintenance and replacement efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A corrosion-resistant eyeplate structure includes an eyeplate assembly. A flow cylinder assembly is installed inside the eyeplate assembly.

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] A corrosion-resistant eye plate structure includes an eye plate assembly 1, a flow cylinder assembly 2 installed inside the eye plate assembly 1, the lower end of the flow cylinder assembly 2 being spirally fitted to the inner side of a mounting connection assembly 3, the flow cylinder assembly 2 including a first expansion plate 21, an extension block 23 fixedly connected to the outer side of the first expansion plate 21, a first rubber sealing ring 24 fixedly connected to the bottom end of the first expansion plate 21, a connecting cylinder 26 fixedly connected to the bottom end of the first expansion plate 21, and a threaded groove 25 opened at the lower end of the connecting cylinder 26, the mounting connection assembly 3 including a second expansion plate 31, an internally threaded cylinder 32 fixedly connected to the top end of the second expansion plate 31, a threaded hole 33 opened on the inner side of the internally threaded cylinder 32, a second rubber sealing ring 34 and a third rubber sealing ring 35 fixedly connected to the top end of the second expansion plate 31, and a fourth rubber sealing ring 36 fixedly connected to the top end of the internally threaded cylinder 32.

[0029] As a further implementation of this scheme, an outer cylinder 22 is fixedly connected to the top of the first expansion plate 21. The inner sides of the first expansion plate 21, the outer cylinder 22 and the connecting cylinder 26 are all hollow structures. Through the above arrangement, concrete can flow inside the first expansion plate 21, the outer cylinder 22 and the connecting cylinder 26.

[0030] As a further implementation of this solution, the eye plate assembly 1 includes an eye plate body 11. The upper end of the eye plate body 11 is provided with an anti-rotation groove 12 and an upper mounting groove 13. The middle end of the eye plate body 11 is provided with a receiving groove 14. The lower end of the eye plate body 11 is provided with a lower mounting groove 15. The anti-rotation groove 12 is connected to the upper mounting groove 13. There are multiple anti-rotation grooves 12. The outer side of the extension block 23 is fitted with the inner side of the anti-rotation groove 12. The number of extension blocks 23 is the same as the number of anti-rotation grooves 12. Through the above arrangement, the installation positions of each component are reasonably arranged, making the structure of the device more compact, improving the space utilization and overall stability. The fitting design of multiple anti-rotation grooves 12 and extension blocks 23 facilitates disassembly and replacement, improving the maintenance convenience of the device.

[0031] As a further implementation of this solution, the outer side of the first expansion plate 21 is fitted with the inner side of the upper mounting groove 13, the top of the first expansion plate 21 is flush with the top of the eye plate body 11, the bottom of the first rubber sealing ring 24 is fitted with the bottom of the upper mounting groove 13, the upper mounting groove 13, the receiving groove 14 and the lower mounting groove 15 are connected, the outer side of the connecting cylinder 26 is fitted with the inner side of the receiving groove 14, and a gap is provided between the bottom of the connecting cylinder 26 and the bottom of the eye plate body 11. Through the above settings, the tight fit between the first expansion plate 21 and the upper mounting groove 13 and the fit design between the first rubber sealing ring 24 and the upper mounting groove 13 effectively prevent concrete from leaking from the gap, enhance the sealing and reliability of the device, and at the same time ensure the flatness of the overall structure. The installation connecting component 3 can be embedded into the interior of the eye plate body 11, reducing the space occupation. At the same time, the gap design between the connecting cylinder 26 and the eye plate body 11 provides convenience for the installation connecting component 3 to be embedded into the interior of the eye plate body 11.

[0032] As a further implementation of this solution, the second expansion plate 31 is embedded inside the lower mounting groove 15. The bottom end of the second expansion plate 31 is flush with the bottom end of the eye plate body 11. The second expansion plate 31 has a through hole with the same diameter as the inner hollow structure of the first expansion plate 21. The top end of the third rubber sealing ring 35 is fitted with the top end of the lower mounting groove 15, the top end of the second rubber sealing ring 34 is fitted with the bottom end of the connecting cylinder 26, the internal threaded cylinder 32 is spirally fitted with the threaded groove 25 through the threaded hole 33, and the top end of the fourth rubber sealing ring 36 is fitted with the upper end of the threaded groove 25. Through the above settings, precise docking between components is achieved, improving the assembly accuracy and sealing performance of the device. At the same time, it facilitates the flow of internal fluids, effectively prevents concrete leakage, enhances the sealing and durability of the device, makes installation and disassembly more convenient, and improves maintenance efficiency.

[0033] Workflow: When replacing the flow cylinder assembly 2, rotate the second expansion plate 31. The second expansion plate 31 causes the entire mounting connection assembly 3 to rotate. When the internal threaded cylinder 32 rotates, the threaded hole 33 disengages from the threaded groove 25. Because the extension block 23 is in close contact with the inside of the anti-rotation groove 12, the flow cylinder assembly 2 will not rotate when the mounting connection assembly 3 rotates. After the mounting connection assembly 3 disengages from the flow cylinder assembly 2, the anti-rotation groove 12 and the connecting cylinder 26 can be directly removed from the inside of the upper insert groove 13 and the receiving groove 14. Then, the intact flow cylinder assembly 2 is installed, and the extension block 23 is removed. Align the connecting cylinder 26 with the anti-rotation groove 12 and insert it into the receiving groove 14. When the bottom end of the first rubber sealing ring 24 is in contact with the lower end of the upper mounting groove 13, the lower part of the connecting cylinder 26 is now inside the lower mounting groove 15. Then, fix the mounting connecting assembly 3 with the flow cylinder assembly 2, align the internal threaded cylinder 32 with the threaded groove 25, and rotate the second expansion plate 31. With the threaded hole 33 and the threaded groove 25 spirally engaged, the second expansion plate 31 and the internal threaded cylinder 32 gradually move upward. When the second expansion plate 31 is inside the lower mounting groove 15, the internal threaded cylinder 32 connects the connecting cylinder 26. The connecting sleeve 26 and the first expansion plate 21 are pulled upwards, causing the first rubber sealing ring 24 to be tightly attached to the lower end of the upper mounting groove 13. Simultaneously, the fourth rubber sealing ring 36 is tightly attached to the upper end of the threaded groove 25, the third rubber sealing ring 35 is tightly attached to the upper end of the lower mounting groove 15, and the second rubber sealing ring 34 is tightly attached to the bottom end of the connecting sleeve 26. The first rubber sealing ring 24 prevents concrete from entering the receiving groove 14 from between the first expansion plate 21 and the eye plate body 11. The third rubber sealing ring 35 further prevents concrete from entering the threaded groove 25 and the receiving groove 14 from between the eye plate body 11 and the connecting sleeve 26. The interior of the receiving trough 14 is sealed by the second rubber sealing ring 34, which prevents concrete from entering the receiving trough 14 and the threaded groove 25 from between the second expansion plate 31 and the first expansion plate 21. Based on the above principles, the device is designed with a detachable structure to prevent the entire material cylinder assembly 2 from being replaced after wear, thus reducing the cost of use. At the same time, when replacing the device, the traditional method of fixing each bolt individually is changed, making the device operation more convenient. In addition, the device has good sealing after replacement, which can prevent concrete from seeping into the interior of the device, avoiding great difficulties in later maintenance and improving the convenience of device maintenance.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
