Abstract
Description
Technical Field
[0001] The present application relates to the technical field of ships, and specifically discloses a liftable ship-use driving platform. Background Art
[0002] Ship transportation is one of the commonly used modes of transportation for transporting passengers or goods. When a ship is transporting on an inland river, the draft of the ship is determined by the weight of the cargo carried by the ship. When the weight of the cargo carried by the ship is light, the draft of the ship is small, making the ship float. When the ship encounters a bridge, it cannot pass under the bridge. Therefore, most ships traveling on inland rivers are equipped with a lifting bridge, so that when the ship's draft is small, the bridge can be lowered to pass through the bridge.
[0003] In the prior art, the navigation platform on the ship is mostly controlled by the oil cylinders installed at the four corners to control the lifting and lowering of the navigation platform, and the height of the navigation platform is controlled by adjusting the extension length of the output end of the oil cylinder. However, in the prior art, there is no buffer protection structure under the navigation platform. When the navigation platform is raised and hydraulic oil leaks or the hydraulic cylinder breaks, there is no protection structure during the rapid sinking process of the navigation platform.
[0004] Therefore, in view of this, the inventor provides a marine liftable driving platform to solve the above-mentioned problems. Utility Model Content
[0005] The utility model aims to solve the problem that the conventional liftable driving platform of a ship is not provided with a buffer protection structure and lacks a buffer structure to protect the internal personnel when the driving platform sinks rapidly.
[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a ship-use liftable driving platform, including a cockpit and a supporting and protective structure arranged under the cockpit, the supporting and protective structure including a lifting mechanism arranged on the hull and used to lift the cockpit and a buffer mechanism respectively mounted on the lifting mechanism and moving synchronously with the lifting mechanism.
[0007] Furthermore, lifting grooves for accommodating the lifting mechanism and the buffer mechanism are respectively opened around the cockpit.
[0008] Furthermore, the lifting mechanism includes lifting cylinders respectively fixed to the hull and respectively accommodated in the lifting slots, and output ends of the lifting cylinders are respectively fixed to the top surface of the lifting slots.
[0009] Furthermore, the buffer mechanism includes buffer sleeves respectively sleeved outside the lifting cylinder and buffer sleeves slidably connected to the buffer sleeves. The top of the buffer sleeve is provided with a buffer groove for accommodating and fitting with the outer wall of the buffer sleeve. A sealing block is provided between the top of the buffer sleeve and the output end of the lifting cylinder.
[0010] Furthermore, a synchronous connecting block is fixedly connected to the gap between the buffer sleeve and the outer wall of the cockpit.
[0011] Furthermore, a support ring platform having an outer diameter equal to that of the buffer sleeve is fixedly connected to the top end of the buffer sleeve.
[0012] The principle and effect of this scheme are:
[0013] 1. Compared with the prior art, the utility model installs a supporting and protective structure under the traditional cockpit, and the cockpit and the supporting and protective structure together constitute a liftable driving platform, and the lifting mechanism in the supporting and protective structure realizes the lifting and lowering control function of the cockpit. When the cockpit is lifted or lowered, the buffer mechanism moves synchronously. When the cockpit sinks rapidly, the buffer mechanism buffers the landing of the cockpit, which solves the problem that the liftable driving platform of the traditional ship is not provided with a buffer protection structure, and there is a lack of a buffer structure to protect the internal personnel when the driving platform sinks rapidly.
[0014] 2. Compared with the prior art, the lifting mechanism of the utility model adopts a lifting cylinder, and the lifting height of the cockpit is controlled by the output end of the lifting cylinder. During the lifting and lowering process of the lifting cylinder, the buffer sleeve moves synchronously with the output end of the lifting cylinder, and the output end of the lifting cylinder is used as the power to drive the buffer sleeve to move. When the cockpit sinks rapidly, the output end of the lifting cylinder loses power, and the force on the buffer sleeve comes from the dead weight of the cockpit. The air inside the buffer groove of the buffer sleeve plays a buffering role on the buffer sleeve. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0019] The figure marks in the drawings of the specification include: hull 1, cockpit 2, buffer sleeve 3, buffer groove 4, buffer sleeve 5, lifting cylinder 6, output end 7 of the lifting cylinder, support ring platform 8, sealing block 9, synchronous connection block 10.
[0020] A marine raisable driving platform, for example Figure 1 and Figure 2 As shown:
[0021] It comprises a cockpit 2 and a supporting protective structure installed below the cockpit 2, wherein the supporting protective structure is installed on the hull 1 and is used to support and lift the cockpit 2. After the cockpit 2 is lifted by the supporting protective structure, a better driving vision can be obtained.
[0022] The supporting and protective structure includes a lifting mechanism installed on the hull 1 and used to lift the cockpit 2, and a buffer mechanism respectively mounted on the lifting mechanism and capable of synchronously moving with the lifting mechanism. Specifically, a lifting groove for accommodating the lifting mechanism and the buffer mechanism is respectively opened around the cockpit 2. When the cockpit 2 is at the bottom, the lifting mechanism and the buffer mechanism are completely placed in the lifting groove. The cockpit 2, the lifting mechanism and the buffer mechanism together form a liftable driving platform.
[0023] The lifting mechanism comprises four lifting cylinders 6 respectively fixedly mounted on the hull 1, and the output ends 7 of the lifting cylinders are respectively fixedly mounted on the top surfaces of the corresponding lifting slots.
[0024] The buffer mechanism includes a buffer sleeve 3 respectively sleeved and fixed on the outside of the lifting cylinder 6 and a buffer sleeve 5 installed on the buffer sleeve 3 and capable of sliding up and down. The bottom of the buffer sleeve 3 is fixed on the hull 1, and a buffer groove 4 for accommodating the buffer sleeve 5 is opened inwardly at the top of the buffer sleeve 3, and the outer wall of the buffer sleeve 5 fits the inner wall of the buffer groove 4, and the air between the bottom of the buffer sleeve 5 and the buffer groove 4 is sealed. The buffer sleeve 5 is also coaxially sleeved on the outside of the output end 7 of the lifting cylinder, and a sealing block 9 is fixedly installed between the top of the buffer sleeve 5 and the end of the output end 7 of the lifting cylinder.
[0025] Furthermore, a synchronous connection block 10 is fixedly installed in the gap between the buffer sleeve 5 and the outer wall of the cockpit 2 to prevent rainwater and river water from entering the gap and causing rust during use.
[0026] Furthermore, a supporting ring 8 having an outer diameter equal to that of the buffer sleeve 3 is fixedly mounted on the top of the buffer sleeve 5 to play a further sealing role and close the existing gap when the cockpit 2 is at the bottom.
[0027] When the utility model is in use, the lifting height of the cockpit 2 is controlled by the output end 7 of the lifting cylinder. During the lifting and lowering process of the lifting cylinder 6, the buffer sleeve 5 moves synchronously with the output end 7 of the lifting cylinder, and the output end 7 of the lifting cylinder is used as a power to drive the buffer sleeve 5 to move. When the cockpit 2 sinks rapidly, the output end 7 of the lifting cylinder loses power, and the force on the buffer sleeve 5 comes from the deadweight of the cockpit 2. The air inside the buffer groove 4 of the buffer sleeve 3 plays a buffering role on the buffer sleeve 5.
[0028] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
