DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0016] Example: See Figure 1 - Figure 4The utility model provides a technical solution: a single-hanging-point split gate hoist, comprising: a frame 1; a water pipe 2, the water pipe 2 is used for drainage, and the outer wall of the water pipe 2 is fixedly connected to the inner wall of the frame 1; a limiter 3, the limiter 3 is used to assist the hoist in opening and closing the gate, and the outer wall of the limiter 3 is fixedly connected to the inner wall of the frame 1; a water stop gate 4, the water stop gate 4 is used to block the water flow, and the outer wall of the water stop gate 4 is slidably connected to the inner wall of the limiter 3; a wire rope 5, the wire rope 5 is used to pull the water stop gate 4, and the outer wall of the wire rope 5 is fixedly connected to the top of the water stop gate 4 through a hook; the hoist also includes: a winding device 6, the winding device 6 is used to wind up the wire rope 5, and the outer wall of the winding device 6 is fixedly connected to the inner wall of the frame 1; the winding device 6 includes a bidirectional servo motor 61, a limiting column 68 is arranged on the outside of the bidirectional servo motor 61, and a worm 62 is fixedly connected to the output end of the bidirectional servo motor 61, and the worm 62 is away from one end of the bidirectional servo motor 61 A fixing block 63 is fixedly connected, and a winding drum 66 is slidably connected to the outer wall of the limiting column 68. A traction rope 67 is fixedly connected to the outer wall of the winding drum 66. A worm gear 64 is arranged above the traction rope 67. The top of the winding drum 66 is rotatably connected to the threaded drum 65. After the bidirectional servo motor 61 is started, it drives the worm 62 on both sides to rotate. Driven by the worm 62 on both sides, the worm gear 64 on the frame 1 starts to rotate. Since the inner wall thread of the worm gear 64 is engaged with the thread of the threaded drum 65, and the limiting column 68 limits the rotation of the threaded drum 65, when the worm gear 64 rotates at a uniform speed, the threaded drum 65 will move downward at a uniform speed. Since the winding drum 66 is rotatably connected to the bottom of the threaded drum 65, the winding drum 66 will descend along the limiting column 68 while the worm gear 64 rotates, and the traction rope 67 is fixed on the winding drum 66. At this time, the traction rope 67 is pulled and wound on the winding drum 66, and the wire rope 5 is pulled at the same time to be wound on the winding drum 66.

[0017] The outer wall of the wire rope 5 is rollingly connected with a shock absorbing device 7, the outer wall of the water stop gate 4 is slidingly connected to the inner wall of the frame 1, the outer wall of the water stop gate 4 is in contact with the outer wall of the water pipe 2, the outer wall of the bidirectional servo motor 61 is fixedly connected to the inner wall of the frame 1, the top of the frame 1 is fixedly connected to the bottom of the fixed block 63, the inner wall of the frame 1 is fixedly connected to the bottom of the limit column 68, the inner wall of the frame 1 is rotatably connected to the outer wall of the worm wheel 64, the top of the wire rope 5 is fixedly connected to the outer wall of the traction rope 67, the worm wheel 64 is meshed with the worm 62, and the inner wall of the worm wheel 64 is connected to the threaded cylinder The outer wall of 65 is threadedly connected, the outer wall of the threaded cylinder 65 is slidably connected to the outer wall of the limit column 68, the outer wall of the winding cylinder 66 is slidably connected to the inner wall of the worm gear 64, and the winding cylinder 66 descends at a uniform speed during the winding process of the wire rope 5, so that the wire rope 5 can be arranged and wound on the winding cylinder 66, avoiding overlapping winding of the wire rope 5. At the same time, due to the winding of the wire rope 5, the wire rope 5 will pull the water stop gate 4. After the water stop gate 4 rises along the limiter 3, it will no longer block the water pipe 2, so that the water pipe 2 can drain normally, thereby achieving the purpose of simultaneously controlling the opening of the gate by a single motor.

[0018] The shock absorbing device 7 includes a movable block 71, the inner wall of the movable block 71 is slidably connected to the outer wall of the limiter 3 through a movable groove 72, and the movable groove 72 is opened in the wall of the movable block 71, the inner wall of the movable block 71 is rotatably connected to the limit shaft 73, the outer wall of the movable block 71 is fixedly connected to a damping rod 74, and a compression spring 75 is arranged on the outside of the damping rod 74, and one end of the damping rod 74 away from the movable block 71 is fixedly connected to a limit plate 76, the outer wall of the limit shaft 73 is rollingly connected to the outer wall of the wire rope 5, one end of the compression spring 75 is fixedly connected to the outer wall of the movable block 71, and the other end of the compression spring 75 is fixedly connected to the outer wall of the limit plate 76, and the outer wall of the limit plate 76 is connected to the inner wall of the frame 1 The fixed connection makes it difficult for the wire rope 5 to jump out of the groove due to jumping under the clamping of the limit shaft 73 and the movable block 71. When the wire rope 5 vibrates, the wire rope 5 transmits the force generated by the vibration to the movable block 71, so that the movable block 71 slides on the limiter 3 through the movable groove 72. At this time, a part of the kinetic energy brought by the vibration is converted into kinetic energy generated by the movement. At the same time, when the movable block 71 slides, it will cooperate with the limit plate 76 to squeeze the damping rod 74 and the compression spring 75. The damping rod 74 and the compression spring 75 cooperate to convert the kinetic energy into internal energy. Under the influence of the damping rod 74, the damping rod 74 and the compression spring 75 are slowly released, thereby reducing the impact of the vibration of the wire rope 5.

[0019] Working principle:

[0020] When in use, when the hoist needs to drain water, the winding device 6 is started, and the bidirectional servo motor 61 is started to drive the worms 62 on both sides to rotate. At the same time, the worms 62 are positioned by the fixing blocks 63. Driven by the worms 62 on both sides, the worm wheel 64 on the frame 1 starts to rotate. Since the inner wall thread of the worm wheel 64 is meshed with the thread of the threaded barrel 65, and the limit column 68 limits the rotation of the threaded barrel 65, when the worm wheel 64 rotates at a uniform speed, the threaded barrel 65 will move downward at a uniform speed. Since the winding barrel 66 is connected to the bottom of the threaded barrel 65, the winding barrel 66 will rotate along the limit column while rotating with the worm wheel 64. The column 68 descends, and the traction rope 67 is fixed on the winding drum 66. At this time, the traction rope 67 is pulled and wound on the winding drum 66, and at the same time, the wire rope 5 is pulled to make the wire rope 5 wound on the winding drum 66. Since the winding drum 66 descends at a uniform speed during the winding process of the wire rope 5, the wire rope 5 can be arranged and wound on the winding drum 66, avoiding overlapping winding of the wire rope 5. At the same time, due to the winding of the wire rope 5, the wire rope 5 will pull the water stop gate 4. After the water stop gate 4 rises along the limiter 3, it will no longer block the water pipe 2, so that the water pipe 2 can drain normally, thereby achieving the purpose of controlling the opening of the gate at the same time by a single motor.

[0021] A shock absorbing device 7 is provided. Since the steel wire rope 5 has a certain deformation capacity, even if the winding device 6 prevents the steel wire rope 5 from jumping due to being released after overlapping, the steel wire rope 5 will still swing and produce lateral vibration when winding and releasing, causing the steel wire rope 5 itself to be worn. The vibration can be reduced by providing the shock absorbing device 7. When the movable block 71 changes the pulling direction of the steel wire rope 5, a limit shaft 73 is provided on the surface of the steel wire rope 5 in a rolling manner. Under the clamping of the limit shaft 73 and the movable block 71, it is difficult for the steel wire rope 5 to jump due to jumping. When the steel wire rope 5 vibrates, the steel wire rope 5 will vibrate and produce The generated force is transmitted to the movable block 71, so that the movable block 71 slides on the limiter 3 through the movable groove 72. At this time, a part of the kinetic energy brought by the vibration is converted into kinetic energy generated by the movement. At the same time, while sliding, the movable block 71 will cooperate with the limit plate 76 to squeeze the damping rod 74 and the compression spring 75. The damping rod 74 and the compression spring 75 cooperate to convert the kinetic energy into internal energy. Under the influence of the damping rod 74, the damping rod 74 and the compression spring 75 are slowly released, thereby reducing the impact on the vibration of the wire rope 5, thereby achieving the purpose of shock absorption and protection of the wire rope 5.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
