Description
Technical Field
[0001] The utility model relates to the technical field of production and collection of prestressed anchor rings, in particular to a prestressed anchor ring collecting device. Background Art
[0002] Prestressed anchor rings are a type of prestressed tension anchoring component widely used in civil engineering and construction. Prestressed anchor rings are typically used in conjunction with clips, utilizing a tapered hole-based wedging principle to effectively anchor rebar or strands installed within structural components. During the prestressing process, prestressing is first applied to the rebar or strand using a jack. Subsequently, the prestressed anchor rings and clips work together to anchor the prestressed rebar or strand, applying prestress to the rebar or strand. This prestress is transferred through the rebar or strand to the structural component, creating a certain amount of prestress and compressive deformation in the tensile regions of the structural component before it is subjected to external loads, thus creating a long-lasting and effective prestressed state. This prestressed state effectively offsets the tensile stress caused by external loads, improving the structural component's crack resistance, stiffness, and durability. In general, prestressed anchor rings, as prestressed tension anchoring components in the fields of civil engineering and construction, play a vital role in the fields of civil engineering and construction, and are one of the key components to ensure project quality and safety.
[0003] The production process for prestressed anchor rings is a complex and delicate one, encompassing several key steps. First, the appropriate steel material is selected for blanking. Cutting equipment accurately cuts the steel rings to ensure the size and shape of the resulting rings meet subsequent processing requirements. Next, suitable drilling equipment is used to drill holes in the cut steel rings, forming the basic structure of the prestressed anchor ring. After drilling, the prestressed anchor rings undergo heat treatment. This process, through heating and cooling, improves the material's properties, thereby enhancing the ring's load-bearing capacity and durability. Following heat treatment, surface treatment is another crucial step. Sandblasting or shot blasting is typically used to remove surface oxides and impurities, enhancing surface strength and corrosion resistance. Finally, to ensure the quality and performance of the prestressed anchor rings, rigorous inspection is required for various parameters, including dimensions and mechanical properties. However, after completing these critical steps—blanking, drilling, heat treatment, surface treatment, and inspection—the finished products need to be collected and sorted for smooth transfer to the next process. Due to the relatively heavy weight of prestressed anchor rings, manual collection and sorting of the products is not only tedious but also greatly increases the labor intensity of the processing personnel, thereby affecting the production efficiency of prestressed anchor rings. Therefore, there is room for improvement in the production and collection of prestressed anchor rings to facilitate the collection of prestressed anchor rings, better meet the needs of prestressed anchor ring production, and thus help improve the market promotion of prestressed anchor rings.

[0021] like Figures 1 to 5As shown, a prestressed anchor ring collecting device includes a workbench 1, a first telescopic cylinder 2 is horizontally arranged on the workbench 1, a fixed plate 3 is arranged on the telescopic end of the first telescopic cylinder 2, a storage groove 4 is opened in the middle of the fixed plate 3, a disc 5 is movably sleeved in the storage groove 4, a fixed frame 6 with a square frame structure is arranged above the disc 5, a frame 7 is arranged between the fixed frame 6 and the workbench 1, the fixed frame 6 is installed on the workbench 1 through the frame 7, a plurality of fixed blocks 8 are arranged on the fixed frame 6, and the plurality of fixed blocks 8 are evenly arranged on the fixed frame 6, the outer sides of the fixed blocks 8 are hinged on the top surface of the fixed frame 6, the inner sides of the fixed blocks 8 are located above the inner cavity of the fixed frame 6, a second telescopic cylinder 9 is vertically arranged below the fixed frame 6, the second telescopic cylinder 9 is installed on the workbench 1, a sleeve hole 10 is opened on the fixed plate 3, the sleeve hole 10 is located below the storage groove 4, the sleeve hole 10 is connected with the storage groove 4, and the sleeve hole 10 is sleeved on the telescopic end of the second telescopic cylinder 9. By placing the prestressed anchor ring on the fixed plate 3, the disc 5 is positioned below the prestressed anchor ring. Therefore, when the second telescopic cylinder 9 is extended, it can lift the disc 5 upward, thereby driving the disc 5 and the prestressed anchor ring toward the fixed frame 6. The diameter of the disc 5 is no larger than the outer diameter of the prestressed anchor ring, the inner diameter of the fixed frame 6 is no smaller than the outer diameter of the prestressed anchor ring, the outer diameter of the prestressed anchor ring is no smaller than the maximum spacing between the plurality of fixed plates 3, and the diameter of the disc 5 is no larger than the spacing between the plurality of fixed plates 3. Therefore, when the prestressed anchor ring passes through the fixed frame 6, the prestressed anchor ring lifts the fixed block 8 to rotate. After the prestressed anchor ring passes through the fixed frame 6, since the outer side of the fixed block 8 is hinged to the fixed frame 6, the rotation angle of the fixed block 8 does not exceed 90 degrees. Therefore, when the fixed block 8 separates from the prestressed anchor ring, the fixed block 8 rotates in the opposite direction, thereby resetting the fixed block 8. When the second telescopic cylinder 9 is controlled to shorten, the fixed block 8 is blocked by the fixed frame 6 and cannot rotate in the opposite direction. The prestressed anchor ring will remain on the fixed block 8, and the disc 5 will pass through the fixed frame 6, thereby separating the prestressed anchor ring, so that the prestressed anchor ring is placed on several fixed blocks 8. By repeatedly placing several prestressed anchor rings on the fixed plate 3, several prestressed anchor rings are stacked on several fixed blocks 8 in sequence. The first telescopic cylinder 2 is used to drive the disc 5 and the fixed plate 3 to move, thereby facilitating the transfer of the prestressed anchor ring.

The threaded holes 11 are internally threaded with long-rod bolts 13, and the through holes 12 are movably fitted on the long-rod bolts 13. A spring 14 is fitted on the long-rod bolts 13, and the two ends of the spring 14 are respectively in contact with the nut of the long-rod bolt 13 and the bottom surface of the fixing plate 3, thereby constraining the movement of the disc 5 and improving the stability of the movement of the disc 5.
[0023] In this embodiment, two limit blocks 15 are provided above the fixed plate 3. The two limit blocks 15 are installed on both sides of the top surface of the fixed plate 3 by screws. The sides of the two limit blocks 15 close to the disc 5 are set to arc surfaces. The centers of the arc surfaces of the two limit blocks 15 are located on the same straight line. The diameter of the arc surface of the limit block 15 is consistent with the outer diameter of the prestressed anchor ring, so as to facilitate the positioning of the prestressed anchor ring placed on the fixed plate 3 to facilitate the collection of the prestressed anchor ring.
[0024] Specifically, the number of the fixed frames 6 is not less than two, and several fixed frames 6 are arranged on the frame 7 in sequence along the telescopic direction of the first telescopic cylinder 2, thereby creating multiple collection areas to improve the collection capacity of the present invention. A positioning groove is provided on the top surface of the frame 7, and several fixed frames 6 are movably mounted in the positioning groove. The external structure composed of several fixed frames 6 is consistent with the inner cavity structure of the positioning groove. Several support blocks 16 are provided on the frame 7, and several support blocks 16 are evenly arranged on the top surface of the frame 7. Several support blocks 16 are respectively installed on the frame 7 by screws. The bottom surface of the support block 16 is in contact with the top surface of the fixed frame 6, thereby constraining the fixed frame 6. By removing the support block 16, the fixed frame 6 can be taken out, thereby taking out the prestressed anchor ring collected on the fixed frame 6.
[0025] In this embodiment, a support plate 17 is vertically provided on the first telescopic cylinder 2, and the support plate 17 is installed on the workbench 1. A third telescopic cylinder 18 is provided between the first telescopic cylinder 2 and the workbench 1. The telescopic direction of the third telescopic cylinder 18 is parallel to the telescopic direction of the first telescopic cylinder 2. The third telescopic cylinder 18 and the first telescopic cylinder 2 are both installed on the support plate 17. A fixing frame 19 is provided on one side of the third telescopic cylinder 18. The two sides of the fixing frame 19 are respectively installed on the cylinder body of the second telescopic cylinder 9 and the telescopic end of the third telescopic cylinder 18, so that the telescopic operation of the third telescopic cylinder 18 can drive the second telescopic cylinder 9 to move, so as to facilitate the adjustment of the position of the second telescopic cylinder 9 lifting the disc 5.
[0026] Specifically, the first telescopic cylinder 2 is provided with a first guide rail 20 on both sides, a bracket 21 is provided between the first guide rail 20 and the workbench 1, the first guide rail 20 is installed on the workbench 1 through the bracket 21, the first guide rail 20 is movably sleeved with a first slider 22, the first slider 22 is installed on the fixed plate 3, the second telescopic cylinder 9 is provided with a second guide rail 23 on both sides, the second guide rail 23 is installed on the top surface of the workbench 1, the second guide rail 23 is movably sleeved with a second slider 24, the second slider 24 is installed on the fixed frame 19, the extension of the first guide rail 20 The direction and the extension direction of the second guide rail 23 are parallel to the extension direction of the first telescopic cylinder 2.

The slide groove 25 is provided on the workbench 1 along the extension direction of the first telescopic cylinder 2. The second telescopic cylinder 9 is located in the slide groove 25. The side surface of the second telescopic cylinder 9 contacts the groove wall of the slide groove 25, thereby constraining the movement of the fixed plate 3 and the second telescopic cylinder 9, reducing the shaking of the fixed plate 3 and the second telescopic cylinder 9, and thus improving the stability of the movement of the fixed plate 3 and the second telescopic cylinder 9.
[0027] Please refer again Figure 1 A plurality of limit columns 26 are provided above the fixed frame 6. The limit columns 26 are respectively located on both sides of the fixed frame 6. The bottom ends of the limit columns 26 are all installed on the fixed frame 6, thereby constraining the two sides of the fixed frame 6 to prevent the prestressed anchor ring from sliding off from both sides of the fixed frame 6.
[0028] The method of using this product is as follows: Figures 1 to 6As shown, the workbench 1 is first installed so that it is mounted on one side of the discharge port of the production or inspection equipment, with the fixed plate 3 and the circular disc 5 adjacent to the discharge port. This ensures that after the workbench 1 is installed, the telescopic operations of the first, second, and third telescopic cylinders 2, 9, and 18 will not be interfered with. Then, two stoppers 15 are installed on either side of the fixed plate 3 according to the size of the prestressed anchor. This facilitates positioning of the prestressed anchor placed on the fixed plate 3. The telescopic expansion and contraction of the first and third telescopic cylinders 2 and 18 are measured based on the positions of several fixed frames 6, facilitating the use of the second telescopic cylinder 9 to transport the prestressed anchor rings above the fixed frames 6. The prestressed anchor rings delivered from the discharge port of the production or inspection equipment are then sequentially placed on the fixed plate 3, such that they contact the two stoppers 15. By controlling the first telescopic cylinder 2 to shorten to a specified length, the prestressed anchor rings are moved between the second telescopic cylinder 9 and the fixed frames 6. Next, the second telescopic cylinder 9 is controlled to extend, thereby driving the disc 5 and the prestressed anchor ring to move above several fixed blocks 8, and then the second telescopic cylinder 9 is controlled to shorten, so that the prestressed anchor ring remains on several fixed blocks 8, thereby completing the assembly of the prestressed anchor ring. Finally, the first telescopic cylinder 2 is controlled to extend and reset to facilitate the repeated collection of several prestressed anchor rings. It should be noted that in order to facilitate the carrying of more prestressed anchor rings, the expansion and contraction calculations of the first telescopic cylinder 2 or the second telescopic cylinder 9 are calculated to facilitate the understanding of the prestressed anchor rings placed on the fixed frame 6. If the number of prestressed anchor rings placed on the fixed frame 6 reaches the rated number, the third telescopic cylinder 18 is controlled to extend or shorten to the specified length to facilitate the delivery of the prestressed anchor ring to another fixed frame 6.
[0029] Through this embodiment, the first telescopic cylinder 2 is set up to drive the disc 5 and the fixed plate 3 to move, thereby driving the prestressed anchor ring placed on the fixed plate 3 to move between the second telescopic cylinder 9 and the fixed frame 6, so as to facilitate the use of the second telescopic cylinder 9 to drive the prestressed anchor ring for collection. Moreover, this embodiment forms a one-way movement path for the prestressed anchor ring by providing a fixed frame 6 and several fixed blocks 8 hinged on the fixed frame 6, and the inner cavity diameter of the fixed frame 6 is not less than the outer diameter of the prestressed anchor ring, and the outer diameter of the prestressed anchor ring is not less than the maximum spacing between several fixed plates 3, so that when the second telescopic cylinder 9 is extended, it drives the disc 5 and the prestressed anchor ring to move toward the fixed frame 6. After the disc 5 passes through the several fixed blocks 8, the several fixed blocks 8 support the prestressed anchor ring during the process of controlling the second telescopic cylinder 9 to shorten, so that the prestressed anchor ring is separated from the disc 9, and then the several prestressed anchor rings are repeatedly placed on the fixed plate 3 to stack the several prestressed anchor rings on the several fixed blocks 8 in sequence, thereby meeting the collection requirements of the prestressed anchor rings.
[0030] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention.
