Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw-type gate opening and closing technology, and in particular to a double-suspension-point screw gate opening and closing machine. Background Technology
[0002] With economic development and increasing demand for water resource utilization and allocation, large-scale water conservancy projects are constantly being built. The gates in these projects are often large in size and weight. Single-point hoisting machines cannot provide sufficient lifting force and stability to open and close the gates evenly and smoothly. Double-point screw hoists act on the gates simultaneously through two lifting points, which can better distribute the load and ensure the balance and synchronization of the gates during the opening and closing process, thereby meeting the operational requirements of large gates.
[0003] However, dual-screw gate hoists need to ensure the synchronous operation of the two lifting points to ensure the balance and normal opening and closing of the gate. However, due to certain manufacturing errors and installation deviations in the transmission systems of the two screws, as well as the influence of different resistances during operation, it is difficult to achieve high-precision synchronous control.
[0004] Therefore, we provide a dual-suspension-point screw gate hoist to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a double-suspension-point screw gate hoist to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a double-suspension-point screw hoist, comprising an intermediate shaft support and a screw-type double-sided hoisting and hoisting mechanism, wherein the screw-type double-sided hoisting and hoisting mechanism is provided on one side of the intermediate shaft support. The screw-type double-sided hoisting opening and closing mechanism includes a fixed connection component, an opening and closing lifting component, and an auxiliary opening and closing component. The fixed connection component is provided on the upper side of the intermediate shaft support, the opening and closing lifting component is provided on one side of the fixed connection component, and the auxiliary opening and closing component is provided on one side of the opening and closing lifting component.
[0007] Preferably, the fixed connection assembly includes a support clamp and a connecting fixed support rod. The support clamp is welded and fixed to the upper side of the intermediate shaft support seat, and the connecting fixed support rod is movably sleeved on the inner side of the support clamp.
[0008] Preferably, the opening and closing lifting assembly includes an opening and closing head, a rotating shaft, an opening and closing base, a connecting belt, and a drive motor. The opening and closing head is fixedly connected to one side of the connecting and fixed support rod. The rotating shaft is fixedly connected to one side of the opening and closing head via a bearing. The opening and closing base is fixedly connected to the lower side of the opening and closing head. A connecting belt is sleeved on the surface of the rotating shaft. The drive motor is fixedly connected to one side of the opening and closing base. The drive motor and the rotating shaft form a sleeved transmission structure through the connecting belt.
[0009] Preferably, the auxiliary opening and closing assembly includes a rotating screw, an opening degree encoding module, a small emergency control box, and a hand crank. The rotating screw is threadedly connected to the inner side of the opening and closing head. The opening degree encoding module is fixedly connected to one side of the rotating screw. The small emergency control box is electrically connected to one side of the opening and closing base. The hand crank is rotatably connected to the other side of the opening and closing head. The rotating screw passes through the opening and closing head and the opening and closing base.
[0010] Compared with the prior art, the beneficial effects of this utility model are: With the screw-type double-sided hoisting opening and closing mechanism, during use, it is operated by... Figure 1 It is known that the connecting fixed support rods are respectively sleeved with the rotating shafts at both ends. When the rotating shafts at both ends rotate, the rotation speed at both ends can be relatively balanced and stabilized by the connecting fixed support rods, so that the water gates connected to the lower two sides can be lifted at a relatively uniform speed. Similarly, the rotating screw can be raised and lowered by rotating the hand crank. The hand crank is equipped with a hand-electric interlock device with the lifting and lowering assembly. When the hand crank is operated manually, if the hand slips and falls off, the drive motor at the other end will instantly take over and lock the rotating screw, thereby increasing the safety of the manual opening and closing process.
