[0030] This invention can be installed on a high-speed rail track slab assembly line or used alone in conjunction with a high-speed rail track slab mold.
[0031] Taking the assembly line of high-speed railway track slabs as an example:
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model includes two columns 1, a platform 5, a support plate 9, and several tensioning frames 12;
[0033] The two columns 1 are symmetrically distributed, the platform 5 is horizontally placed between the two columns 1 and can move up and down along the columns 1, the support plate 9 is horizontally placed above the platform 5 and can move longitudinally along the platform 5, and the plurality of tensioning frames 12 are evenly placed above the support plate 9 and can move laterally along the support plate 9.
[0034] Vertical linear guide rails 2 are provided on the inner sidewalls of the two columns 1. Slider I4s are provided at both ends of the platform 5, which can slide up and down along the linear guide rails 2. A hydraulic cylinder I3 is provided between the two columns 1. The output end of the hydraulic cylinder I3 is connected to the bottom end of the platform 5. The platform 5 can move up and down along the columns 1 through the hydraulic cylinder I3.
[0035] The top surface of the platform 5 is provided with two longitudinally installed linear guide rails 7, and two sliders II8 correspondingly provided at the bottom of the support plate 9 can slide along the longitudinal linear guide rails 7; it also includes a hydraulic cylinder II6 fixed on the platform, the hydraulic cylinder II6 is placed longitudinally, and its output end is connected to the support plate 9. Through the hydraulic cylinder II6, the support plate 9 can move back and forth longitudinally along the platform 5.
[0036] The top surface of the support plate 9 is provided with several horizontal linear guide rails 10, and the slider III 11 provided at the bottom of each tensioning platform can slide along the corresponding horizontal linear guide rail 10; the bottom of the tensioning platform 12 is also equipped with a servo motor I 15, and the output shaft of the servo motor I 15 is provided with a gear 13, which can mesh with the horizontal rack 14 installed on the support plate 9. Through the servo motor I 15, the tensioning platform 12 can move laterally left and right along the support plate 9.
[0037] A tensioning cylinder 16 is installed in the middle of the tensioning platform 12, and a tensioning rod connector 17 is provided at the end of the tensioning cylinder 16, which can be connected to the tensioning rod of the high-speed railway track slab.
[0038] The top of the tensioning platform 12 is equipped with a locking bracket 20 that can move up and down. A servo motor II 23 is installed on the locking bracket 20. The output end of the servo motor II 23 is equipped with a locking gear 24. After tensioning is completed, the distance can be adjusted by extending and retracting the tensioning cylinder 16 to make the locking gear 24 contact the locking nut on the tensioning rod 18. Then, the servo motor II is started to make the locking gear 25 drive the locking nut to rotate together, so as to achieve the effect of locking the tension.
[0039] The top of the tensioning platform 12 is equipped with a cylinder 19 with its output end facing downward. The output end of the cylinder 19 is connected to the top of the locking bracket 20. The side of the locking bracket 20 is equipped with a vertical linear guide rail 21. The side wall of the tensioning platform 12 is equipped with a corresponding slider IV 22. The slider IV 22 can slide along the vertical linear guide rail 21. Through the cylinder 19, the locking bracket 20 can move up and down.
[0040] There are two hydraulic cylinders I3, which are located near the inner sides of the two columns I.
[0041] Working process: When the high-speed rail track slab mold is transported to the vicinity of this equipment on the production line, the hydraulic cylinder I3 extends or retracts, causing the platform 5 to move upward or downward. It stops when the tension rod connector 17 at the end of the tension cylinder 16 is at the same horizontal center position as the high-speed rail track slab tension rod 18. Then, the servo motor I15 is started, causing the tensioning platform 12 to move left and right. It stops when the tension rod connector 17 at the end of the tension cylinder 16 is at the same vertical center position as the high-speed rail track slab tension rod 18. Next, the hydraulic cylinder II6 extends, and the support plate 9 moves forward, causing the tension rod connector 17 at the end of the tension cylinder 16 to contact and connect with the high-speed rail track slab tension rod 18.
[0042] Next, the tensioning cylinder 16 is activated to prestress the high-speed rail track slab, holding the load for 1 minute after reaching the design value. Then, the cylinder 19 extends, causing the locking gear 24 to contact the tension rod locking nut 25. Simultaneously, the servo motor II 23 is activated, causing the locking gear 24 and the tension rod locking nut 25 to rotate together and lock the tension. After tensioning, the servo motor II 23 is stopped; the cylinder 19 retracts, separating the locking gear 24 from the tension rod locking nut 25; the hydraulic cylinder II retracts, using the tension rod connector 17 at the end of the tensioning cylinder 16 to separate from the high-speed rail track slab tension rod 18. The high-speed rail track slab mold can then proceed to the next process. This invention allows for a continuous cycle of prestressing tensioning of the next set of high-speed rail track slab molds.
[0043] This invention can not only meet the tensioning requirements of different positions of prestressed steel bars in various types of high-speed rail track slabs, but also actively approach and find the position of prestressed steel bars on the high-speed rail track slab mold for tensioning. This avoids the problem of repeated position adjustments of the high-speed rail track slab mold on the assembly line and the problem of tensioning being affected by excessive deviation in the position of the track slab mold.
[0044] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
