Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and particularly relates to a hoisting structure for a radial gate. Background Art

[0002] A radial gate is a gate with a cylindrical partial arc-shaped water retaining surface. The supporting hinge of its supporting arm is located at the center of the circle. When opening and closing, the gate rotates around the supporting hinge. It has no gate slot, has a relatively small hoisting force, and good hydraulic conditions. Therefore, it is widely used in various types of water channels. The opening and closing of the radial gate mainly rely on a hydraulic hoist or a winch hoist to control the opening and closing actions.

[0003] A Chinese patent discloses a radial gate hoisting device with the publication number CN219240474U. It is proposed in the text that "including: a gate, side walls are arranged on the front and rear sides of the gate, and cylinders are connected to the side walls and the lower side of the gate; support columns, four groups of the support columns are respectively arranged at the four corners on the right side of the gate, and the other ends of the upper and lower two groups of support columns are connected to a connecting block, and the other end of the connecting block is connected to a fixed seat. In the utility model, by arranging cylinders, the two ends of the cylinders are respectively hinged to the gate and the side walls. At the same time, the support columns are connected to the rear side of the gate through connecting rods to form a triangular force arm. At the same time, the connecting block is hinged to the fixed seat, which is convenient for opening and closing the radial gate in cooperation with the cylinders. At the same time, a fixed column is provided, a reinforcing rod is connected between the upper and lower support columns, a fixed column is connected between the reinforcing rods, and a steel cable and a connecting sleeve are arranged thereon. The rotating rod is driven to rotate by electric start, the steel cable is wound on the connecting sleeve, and in cooperation with the cylinders, the force arm is lifted to open and close the gate".

[0004] However, in the above scheme, the steel cable cannot be well and evenly wound on the winding drum of the winch. During the actual opening and closing process of the radial gate, the opening and closing action is realized by the rotation of the winding drum to wind and unwind the steel cable. However, during the winding process of the steel cable, it is impossible to ensure that it is evenly distributed on the winding drum, and it is easy to be overly wound locally on the winding drum, which further leads to inconvenience in its use. Therefore, it is very necessary to design a hoisting structure for a radial gate. Summary of the Utility Model

[0029] Embodiment 1

[0030] The preferred embodiment of the opening and closing structure of the arc gate provided by the present utility model is as Figures 1 to 6As shown in the figure: A lifting structure for a radial gate, comprising side walls 2, and a radial gate body 3 rotatably connected to the inner walls of the side walls 2; a fixing plate 5 fixedly connected to one side of the top of the side walls 2; fixing frames 6 symmetrically and fixedly connected to the top of the fixing plate 5, a hoisting drum 11 rotatably connected to the inner walls of the fixing frames 6, a steel cable 10 wound around the surface of the hoisting drum 11, one end of the steel cable 10 being fixedly connected to the top of the radial gate body 3 respectively, one end of the fixing frame 6 being fixedly connected with a servo motor 7, and the output end of the servo motor 7 being fixedly connected to one end of the hoisting drum 11 through a coupling; adjusting components 8 symmetrically assembled on one side of the top of the fixing plate 5, the adjusting components 8 being used to guide the steel cable 10 so that it can be evenly wound around the surface of the hoisting drum 11; a locking component 9 assembled at the middle position of the top of the fixing plate 5, the locking component 9 being used to realize the positioning and locking after the rotation of the hoisting drum 11.

[0031] The adjusting component 8 includes: adjusting frames 805 symmetrically and fixedly connected to the top of the fixing plate 5; a driving motor 802 fixedly connected to one end of the adjusting frame 805, the output end of the driving motor 802 passing through the adjusting frame 805 and being fixedly connected with a threaded rod 803 through a coupling; a threaded block 807 threadedly connected to the surface of the threaded rod 803; a sliding frame 801 fixedly connected to the top of the threaded block 807; guide wheels 808 symmetrically and rotatably connected to the inner walls of the sliding frame 801.

[0032] It should be noted that there are still certain deficiencies in some existing lifting structures for radial gates during actual use. During the winding process of the steel cable 10, it is impossible to ensure its uniform distribution on the hoisting drum 11, which easily causes it to be overly wound locally on the hoisting drum 11, thereby resulting in inconvenience in its use.

[0033] In this embodiment, by starting the servo motor 7 to drive the hoisting drum 11 to rotate, the steel cable 10 is wound around the surface of the hoisting drum 11, so that the radial gate body 3 is opened. After the hoisting drum 11 is relaxed, the radial gate body 3 is closed due to gravity. At the same time, during the relaxation or winding process of the steel cable 10, the driving motor 802 can be started to drive the threaded rod 803 to rotate. By using the threaded fit of the threaded rod 803 and the threaded block 807, and by using the sliding of the sliding block 806 on the surface of the sliding rod 804, the threaded block 807 slides to drive the sliding frame 801 to slide. Furthermore, the rotating guide wheels 808 can be used to drive the guiding movement of the steel cable 10, so that the steel cable 10 can be wound more evenly around the surface of the hoisting drum 11, avoiding excessive winding of the steel cable 10 on the surface of the hoisting drum 11 and causing damage to the equipment, improving its practicability. And after the radial gate body 3 is opened, the locking component 9 can be used to limit and clamp the rotation of the hoisting drum 11, improving the firm stability after the opening of the radial gate body 3.

[0034] In a further preferred embodiment of the present utility model, a sliding rod 804 is fixedly connected to the lower end of the inner wall of the adjusting frame 805, and a sliding block 806 that is slidably engaged with the surface of the sliding rod 804 is fixedly connected to the bottom end of the threaded block 807.

[0035] In this embodiment, by sliding the sliding block 806 on the surface of the sliding rod 804, the sliding direction of the sliding frame 801 is restricted.

[0036] In a further preferred embodiment of the present utility model, the middle position of the surface of the guide wheel 808 is recessed, and two guide wheels 808 are provided on the inner wall of the sliding frame 801.

[0037] In this embodiment, by using the recessed guide wheel 808, the steel cable 10 can be guided more smoothly, reducing the frictional force between the steel cable 10 and the guide wheel 808.

[0040] In this embodiment, after the arc gate body 3 is opened, the pneumatic telescopic rod 905 can be started to drive the sliding seat 910 to slide, so that the brake ring 909 slides tightly against the inner wall of the friction sleeve 906, thereby increasing the anti-slip firmness of the two when they are engaged tightly, realizing the limit fixation of the linkage cylinder 901 after rotation, and further avoiding the hoisting drum 11 from rotating due to the gravity of the arc gate body 3 sliding down, resulting in excessive bearing pressure on the servo motor 7, and improving the stability and firmness of the arc gate body 3 after being lifted and opened. When it is necessary to further open or close the arc gate body 3, start the pneumatic telescopic rod 905 to make the sliding seat 910 slide away from the surface of the linkage cylinder 901, and then the opening and closing action of the arc gate body 3 can be realized by the operation of the servo motor 7. And when the brake ring 909 is severely worn, the fixing bolt 912 can be rotated by a tool until it completely disengages from the inside of the bolt hole 907, and then the brake ring 909 is pushed to make the clamping block 908 slide out of the inside of the clamping groove 911, realizing the disassembly of the brake ring 909. When installing, the clamping block 908 is snapped into the inside of the clamping groove 911, and then the fixing bolt 912 is tightened into the inside of the bolt hole 907 to realize the firm installation between the brake ring 909 and the sliding seat 910.

[0043] In a further preferred embodiment of the present utility model, a slider 902 is fixedly connected to the bottom end of the sliding seat 910, and a sliding groove 903 that is slidably matched with the slider 902 is opened on one side of the top end of the fixing plate 5.

[0044] In this embodiment, by using the sliding of the slider 902 inside the sliding groove 903, the smoothness of the sliding seat 910 after sliding is improved.

[0045] In a further preferred embodiment of the present utility model, an installation component is provided on the surface of the brake ring 909 and the inner wall of the sliding seat 910. The installation component is used to realize the disassembly and assembly between the brake ring 909 and the sliding seat 910. The installation component includes: a clamping groove 911 opened on the inner top wall of the sliding seat 910; a fixing bolt 912 movably connected to the top end of the sliding seat 910, and the bottom end of the fixing bolt 912 extends into the inside of the clamping groove 911; a clamping block 908 fixedly connected to the surface of the brake ring 909; a bolt hole 907 opened at the top end of the clamping block 908, and a threaded fit structure is formed between the inside of the bolt hole 907 and the bottom end of the fixing bolt 912.

[0046] In this embodiment, when the brake ring 909 is severely worn, the fixing bolt 912 can be rotated by a tool until it completely disengages from the inside of the bolt hole 907, and then the brake ring 909 is pushed to make the clamping block 908 slide out of the inside of the clamping groove 911, realizing the disassembly of the brake ring 909. When installing, the clamping block 908 is snapped into the inside of the clamping groove 911, and then the fixing bolt 912 is tightened into the inside of the bolt hole 907, realizing the firm installation between the brake ring 909 and the sliding seat 910.

[0047] In a further preferred embodiment of the present utility model, a clamping structure is formed between the inside of the clamping block 908 and the clamping groove 911, and the shapes of the clamping block 908 and the clamping groove 911 are T-shaped.

[0048] In this embodiment, by using the clamping of the T-shaped clamping block 908 inside the clamping groove 911, the firmness of the initial clamping between the brake ring 909 and the inside of the sliding seat 910 is improved.

[0049] In a further preferred embodiment of the present utility model, a rain shield 1 is fixedly connected to the top end of the fixing plate 5, and the top end of the rain shield 1 is in an inverted triangle shape.
