Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship lift cabin gates, in particular to a ship lift cabin gate with no supporting arm hinge structure. Background Art
[0002] In water conservancy and hydropower projects, the ship lift cabin gate refers to the gate installed at the end of the ship lift cabin. After the cabin is docked with the gate head, a passage in and out of the cabin is formed by opening or closing the cabin gate. Among them, a flat lying door is more common.
[0003] At present, there are common flat lying gates (such as CN201520078571.7-A flat lying gate for a ship lift cabin). They are greatly affected by the water body during the opening and closing process. When they are close to the fully opened or closed position, the gate runs slowly. At the same time, the flat lying gate is greatly affected by the water pressure difference on both sides of the gate during the opening and closing process, which places higher requirements on the design of the opening and closing device and the gate support hinge point.
[0004] At present, there are common sinking arc gates (such as CN200720105047.X "A kind of arc-shaped cabin door for ship lift" and CN201621265911.8 "A cabin door structure for ship lift"). Similar to the surface arc gates in common hydropower and water conservancy projects, there are arm structures or quasi-arm structures in the gate structure, which makes the gate occupy a larger space and increase the weight. In addition, the load on the gate is finally transferred from the arm to the support hinge point, and the load is relatively concentrated, which puts higher requirements on the design of the gate and cabin structure. At the same time, the support hinge of the opening and closing device requires a hole to be opened at the cabin side beam. The dynamic seal here has high design, manufacturing and installation precision, and when the seal ages and a large amount of water enters, it will destroy the balance of the cabin. With the rapid growth of the demand for ships to pass through the dam, the number of ships passing through the dam is increasing, and the tonnage is increasing. It is necessary to propose a faster and more stable cabin gate structure.
[0005] For this reason, it is necessary to propose a new ship lift cabin gate with a non-support arm hinge structure. Utility Model Content
[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a ship lift cabin gate with a support arm hinge structure. The utility model gate can improve the reliability of the opening and closing of the cabin gate while retaining the advantages of the existing design scheme and gate structure, reduce the design difficulty and equipment cost of the gate and the supporting opening and closing device, and thus improve the reliability of the entire ship lift metal structure system.
[0007] The utility model provides the following technical solutions to achieve the above purpose:
[0008] A ship lift cabin gate with an armless hinge structure comprises a cabin, wherein cabin side beams are respectively provided on both sides of the cabin, and an arc-shaped groove is provided at one end of the cabin between the two cabin side beams; an outer slideway and an inner slideway are provided on the inner wall of the cabin side beam, both of which are arc-shaped and match each other, a slideway is formed between the outer slideway and the inner slideway, a door leaf is slidably arranged between the two slideways, the door leaf is arc-shaped and its shape matches the slideway and the arc-shaped groove; and an opening and closing component for driving the door leaf to slide in the slideway is also included.
[0009] In the aforementioned ship lift cabin gate with armless hinge structure, door leaf side beams are respectively provided at the middle of both ends of the door leaf, and at least two main supporting wheels are provided in the door leaf side beams, and the main supporting wheels are slidably arranged between the outer slideway and the inner slideway.
[0010] In the aforementioned ship lift cabin gate with armless hinge structure, side water seals are arranged at the outer edges of both ends of the door leaf; the bottom of the door leaf is connected to, and a water stop seat plate is arranged at the connection.
[0011] In the aforementioned ship lift cabin gate with an armless hinged structure, the opening and closing assembly includes a hoist arranged inside the cabin side beam and a fixed pulley arranged on the top of the cabin side beam; the hoist includes a telescopic device, a pulley is hinged on the top of the telescopic device, and a pull rope is provided on the pulley, and the pull rope extends from the top of the cabin side beam, wraps around the fixed pulley and is connected to the top of the door leaf.
[0012] In the aforementioned ship lift cabin gate with a support armless hinge structure, the tops of both ends of the door leaf are provided with lifting lug plates, which are connected to the pull ropes.
[0013] In the aforementioned ship lift cabin gate with armless hinge structure, the gate leaf comprises a panel, a main beam, a secondary beam and a longitudinal partition.
[0014] In the aforementioned ship lift cabin gate with a support armless hinge structure, the bottom of the outer slideway is connected to the flat section of one end of the cabin where the arc-shaped groove is provided.
[0015] In the aforementioned ship lift cabin gate with a non-support arm hinge structure, the ends of the cabin are the head and tail ends of the cabin.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] 1. The gate of the utility model is less affected by the water body during the opening and closing process, which solves the problem that the gate runs slowly when it is close to the fully opened and closed position and then suddenly accelerates. At the same time, the gate has better tightness when it is fully opened and closed, and its reliability is greatly enhanced.
[0018] 2. The utility model gate has no support arm hinge structure, the gate occupies a small space as a whole, is light in weight, has good economy, and the gate support points are evenly distributed. The load is borne by multiple fixed wheels, and the requirements for the gate and cabin structure design are relatively low.
[0019] 3. The utility model has no dynamic sealing structure. Dynamic sealing has very high requirements on design, manufacturing and installation accuracy, which is very difficult. The utility model structure does not need to open holes in the side beams of the cabin, which solves the problem of unstable cabin balance caused by water entering the inside of the side beams of the cabin due to sealing failure.
