[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 The water conservancy and hydropower construction fastening device in this embodiment includes a base 1, a support rod 2 fixed at the center of the upper surface of the base 1, a fixing block 3 fixed on the upper surface of the support rod 2, and a rotating shaft 4 rotatably connected to the left and right sides of the fixing block 3 through bearings. The opposite sides of the two rotating shafts 4 are provided with a fastening mechanism 5 for providing a fastening effect. The opposite sides of the two rotating shafts 4 penetrate and extend into the inner cavity of the fixing block 3 and are provided with an angle adjustment mechanism 6 for adjusting the angle of the fastening mechanism 5.
[0025] Please see Figure 2To secure the object, the fastening mechanism 5 in this embodiment includes a fixed frame 501 fixed to the opposite sides of two rotating shafts 4. A drive motor 502 is fixed to the top of each opposite side of the fixed frame 501. The output shaft of the drive motor 502 passes through and extends into the inner cavity of the fixed frame 501 and is fixed with a bidirectional screw 503. Screw sleeves 504 are threaded to both ends of the outer surface of the bidirectional screw 503. Positioning half-rings 505 are fixed to the outer surface of the screw sleeves 504. One end of the object to be fastened is inserted between the opposite sides of the two positioning half-rings 505. Then, the drive motor 502 is started. The output shaft of the drive motor 502 rotates, which drives the bidirectional screw 503 to rotate. The rotation of the bidirectional screw 503 causes the two threaded sleeves 504 connected to the left and right ends of its surface to drive the positioning half rings 505 to move relative to each other. The bottom of the left and right side walls of the inner cavity of the fixed frame 501 is fixed with sliding rods 506. The relative movement of the two threaded sleeves 504 can drive the two positioning half rings 505 to move relative to each other. In this way, the two positioning half rings 505 can clamp the left and right sides of the object to be fastened to fasten it.
[0026] In this embodiment, the bidirectional screw 503 is rotatably connected to the top of the opposite side of the left and right side walls of the inner cavity of the fixed frame 501 via a bearing. Two threaded sleeves 504 are symmetrically distributed on the left and right sides of the vertical central axis of the bidirectional screw 503. Two positioning half-rings 505 are Y-axis symmetrical. The bottom of the positioning half-ring 505 is slidably connected to the slide rod 506. The bottom of the positioning half-ring 505 slides on the outer surface of the slide rod 506, which can limit the movement of the threaded sleeves 504.
[0027] Among them, anti-slip pads are fixed on the opposite sides of the two positioning semi-rings 505. The anti-slip pads are rubber pads.
[0028] It should be noted that the design of the drive motor 502 and the bidirectional screw 503 enables automated fastening, improves work efficiency, reduces manual operation time and labor intensity, and the design of the positioning semi-ring 505 and anti-slip pad ensures the stability of the connector, prevents slippage or loosening, and ensures safety and reliability during construction.
[0029] Please see Figures 3 to 4In order to adjust the fastening angle of the object, the angle adjustment mechanism 6 in this embodiment includes a driven bevel gear 601 fixed on the opposite side of the two rotating shafts 4. The driven bevel gear 601 is meshed with the driving bevel gear 602 on the front. The outer surface of the rotating shaft 4 is provided with multiple triangular grooves 603. The left and right ends of the upper side of the fixing block 3 are provided with lifting plates 604. The left and right ends of the lifting plate 604 and the opposite side of the fixing block 3 are fixed with compression springs 605. A triangular prism 606 with one end penetrating through and extending to the lower side of the lifting plate 604 is fixed on the upper surface of the lifting plate 604. Pulling the triangular prism 606 to move upward causes the triangular prism 606 to drive the lifting plate 604 to move upward. The movement of the lifting plate 604 causes the compression spring 605 to be stretched. The movement of the lifting plate 604 simultaneously drives the bottom of the triangular prism 606 to move upward until the bottom of the triangular prism 606 moves out of the inner cavity of the triangular groove 603, which can release the limit on the rotating shaft 4.
[0030] In this embodiment, a drive rod is fixed inside the active bevel gear 602. The front of the drive rod extends through and to the front of the fixed block 3 and is fixed with a handle. The drive rod and the fixed block 3 are rotatably connected by a bearing. The drive rod can be rotated, and the rotation of the drive rod drives the active bevel gear 602 to rotate. The rotation of the active bevel gear 602 causes the driven bevel gear 601, which meshes with it, to rotate. The rotation of the driven bevel gear 601 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the fixed frame 501 to rotate, thereby causing the positioning half ring 505 to rotate, which can adjust the angle of the fastened object.
[0031] Two compression springs 605 are symmetrically distributed on the left and right sides of the vertical central axis of the lifting plate 604. The size of the inner cavity of the Mitsubishi groove 603 is adapted to the size of the Mitsubishi column 606. Mitsubishi holes are opened at both ends of the upper surface of the fixing block 3, and the size of the inner cavity of the Mitsubishi hole is adapted to the size of the Mitsubishi column 606.
[0032] It should be noted that the driven bevel gear 601, the driving bevel gear 602, and the drive rod allow users to easily adjust the angle of the fastening mechanism 5 to adapt to different construction needs. Combined with the compression spring 605 and the Mitsubishi column 606, the position is locked, avoiding the generation of unstable factors.
[0033] The working principle of the above embodiments is as follows:
[0034] (1) When in use, first insert one end of the object to be fastened between the two positioning half rings 505 on opposite sides, then start the drive motor 502. The output shaft of the drive motor 502 rotates and drives the bidirectional screw 503 to rotate. The rotation of the bidirectional screw 503 causes the two threaded sleeves 504 connected to the left and right ends of its surface to drive the positioning half rings 505 to move relative to each other. At this time, the bottom of the positioning half rings 505 slides on the outer surface of the slide rod 506, which can limit the movement of the threaded sleeves 504. The relative movement of the two threaded sleeves 504 can drive the two positioning half rings 505 to move relative to each other. Then the two positioning half rings 505 can clamp the left and right sides of the object to be fastened to fasten it.
[0035] (2) When adjusting the angle of the fixed frame 501, first pull the Mitsubishi column 606 upward, so that the Mitsubishi column 606 drives the lifting plate 604 to move upward. The movement of the lifting plate 604 causes the compression spring 605 to be stretched. The movement of the lifting plate 604 simultaneously drives the bottom of the Mitsubishi column 606 to move upward until the bottom of the Mitsubishi column 606 moves out of the inner cavity of the Mitsubishi groove 603. The limit of the rotating shaft 4 can be released. At this time, the drive rod can be rotated. The rotation of the drive rod drives the active bevel gear 602 to rotate. The rotation of the active bevel gear 602 causes the driven bevel gear 601 that meshes with it to rotate. The rotation of the driven bevel gear 601 drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the fixed frame 501 to rotate, thereby causing the positioning half ring 505 to rotate, so that the angle of the fastened object can be adjusted.
