Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, and in particular to a double linkage drive mechanism and a suspended door structure including the double linkage drive mechanism. Background Technology

[0002] In water conservancy projects, the opening and closing of sluice gates plays a crucial role in flood control, irrigation, water level regulation, and navigation. A suspended gate is a type of sluice gate structure that opens and closes from top to bottom. Traditional suspended gates often employ a single hinge or single-point suspension, driven by a winch or simple hydraulic system for lifting and lowering. With the increasing scale of projects and the diversification of usage scenarios, the structural requirements for sluice gates are becoming increasingly stringent, mainly reflected in:

[0003] 1. Difficulty in adapting to reverse head: Traditional suspended gate structures use winches or simple mechanical opening and closing, which cannot provide resistance to reverse head;

[0004] 2. Opening and closing efficiency and safety: In the event of large water flow or emergencies, the gate must be opened and closed quickly and kept stable to avoid vibration or deformation.

[0005] 3. Structural reliability: Sluice gates are constantly subjected to the impact of water flow, requiring a high-strength structural design and minimizing fatigue damage;

[0006] 4. Applicability and maintainability: For large or special working conditions, sluice gates must be able to be safely deployed or retracted within a limited space, and be easy to inspect and maintain.

[0007] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0008] One of the technical problems to be solved by this utility model is to provide a double-link drive mechanism that can achieve efficient opening and closing in a limited space and has good stability and safety, in order to overcome the shortcomings of the existing technology.

[0009] The second technical problem to be solved by this utility model is to provide a suspended door structure including the above-mentioned double linkage drive mechanism.

The rear end of the other hydraulic opening and closing rod is hinged to the main beam base, and its telescopic end is hinged to the hinge point between the first right connecting rod and the second right connecting rod.

[0016] In a preferred embodiment of this utility model, a limiting device is also included. The limiting device limits the opening or closing of the suspended door to a preset position by means of mechanical limiting or hydraulic locking, so as to prevent the suspended door from moving excessively.

[0017] In a preferred embodiment of the present invention, a buffer device is further included, which buffers the suspended door body by means of a buffer block or a buffer cylinder to reduce the impact of the suspended door body when it moves at the end.

[0018] As a second aspect of this utility model, a suspended door structure includes a suspended door body and a suspended door body drive mechanism. The top of the suspended door body is hinged to the top of the gate chamber via at least one suspension bracket.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0032] See Figures 1 to 4 The figure shows a suspended gate structure, including a suspended gate body 100 and a suspended gate body drive mechanism 200. The top of the suspended gate body 100 is hinged to the top of the gate chamber via two suspension hangers 110, improving the stability of the opening and closing of the suspended gate body 100. The suspended gate body 100 adopts a metal frame structure or a steel plate reinforced skeleton structure to ensure strength and rigidity. The suspended gate body 100 is hinged to the top of the gate chamber via two suspension hangers.

[0033] The suspended door drive mechanism 200 is used to drive the suspended door 100 to open or close. In this embodiment, the suspended door drive mechanism 200 adopts a double-link drive mechanism, which includes a main beam base 210, first left and right connecting rods 220a and 220b, second left and right connecting rods 230a and 230b, and hydraulic opening and closing rods 240a and 240b.

[0034] The main beam base 210 is fixedly installed on the upper part of the gate chamber or on the main structure of the sluice gate, and is used to support and fix the fulcrum of each moving mechanism.

[0035] The first left and right connecting rods 220a and 220b are symmetrically arranged, with one end hinged to the main beam base 210. The second left and right connecting rods 230a and 230b are symmetrically arranged, with one end hinged to the other end of the first left and right connecting rods 220a and 220b, and the other end hinged to the suspended gate body 100. The first left and right connecting rods 220a and 220b and the second left and right connecting rods 230a and 230b together form a parallelogram or near-parallelogram motion linkage mechanism to ensure more stable translation, rotation, or folding movements of the gate during opening and closing.

[0036] The rear ends of the hydraulic opening and closing rods 240a and 240b are hinged to the main beam base 210, and their telescopic ends are hinged to the hinge points between the first left connecting rod 220a and the second left connecting rod 230a, and between the first right connecting rod 220b and the second right connecting rod 230b. Of course, the number of hydraulic opening and closing rods is not limited to that in this embodiment; it can be set to one. The telescopic movement of the hydraulic opening and closing rods 240a and 240b drives the synchronous movement of the double-link mechanism.

[0037] The suspended door drive mechanism 200 also includes a limiting device (not shown in the figure). The limiting device limits the opening or closing preset position of the suspended door 100 by mechanical limiting or hydraulic locking to prevent the suspended door 100 from moving excessively.

[0038] The suspended door drive mechanism 200 also includes a buffer device (not shown in the figure). The buffer device buffers the suspended door body through a buffer block or buffer cylinder, reducing the impact of the suspended door body when it moves at the end and extending the service life of the structure.

[0039] The movement process of the suspended door structure of this utility model is as follows:

[0040] 1. See Figure 2 When the telescopic ends of the hydraulic opening and closing rods 240a and 240b are fully extended, the hydraulic opening and closing rods 240a and 240b drive the suspended door body 100 to flip to a horizontal position through the first left and right connecting rods 220a and 220b and the second left and right connecting rods 230a and 230b, and the suspended door structure is in a non-water-blocking state.

[0041] 2. See Figure 3 When the telescopic ends of the hydraulic opening and closing rods 240a and 240b are in the process of retraction, the hydraulic opening and closing rods 240a and 240b drive the suspended door body 100 to flip downward through the first left and right connecting rods 220a and 220b and the second left and right connecting rods 230a and 230b.

[0042] 3. See also Figure 4 When the telescopic ends of the hydraulic opening and closing rods 240a and 240b are fully retracted, the suspended door body 100 flips to the vertical position, and the suspended door structure is in a water-blocking state.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
