The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
Example 1
Fig. 1 to 4 show a rudder blade support 10 comprising: the first cable fixing device comprises a fixed frame 100, two first actuators 210, two groups of first pulley assemblies 220, a first moving frame 230 and a plurality of first flexible cables 240. The fixing frame 100 has a vertical channel (not shown) passing through the top, and the fixed ends of the two first drivers 210 are fixed on two sides of the fixing frame 100. The two first drivers 210 are used to drive the two sets of first pulley assemblies 220 to move up and down. The first movable frame 230 is located in the vertical passage, and the first movable frame 230 is slidably connected to the fixed frame 100. The first flexible cable 240 is wound around the pulley of the first pulley assembly 220, two ends of the first flexible cable 240 extend vertically and downwardly, one end of the first flexible cable 240 is fixed to the fixed frame 100, and the other end of the first flexible cable 240 is fixed to the first movable frame 230.
In this embodiment, when the two first actuators 210 drive the two sets of first pulley assemblies 220 to move upwards, the distance from one end of the first flexible cable 240 connected to the first moving frame 230 to the first pulley assembly 220 is correspondingly shortened, and at this time, the first flexible cable 240 generates an upward pulling force on the first moving frame 230, and pulls the first moving frame 230 to move upwards in the vertical channel, so as to increase the height of the rudder blade supporting frame 10. Conversely, when the two first actuators 210 drive the two sets of first pulley assemblies 220 to move downwards, the height of the rudder blade support frame 10 can be reduced.
In order to ensure that the first pulley assembly 220 can keep moving in the vertical direction, a vertically extending guide rod 110 is fixed on the fixing frame 100, a guide hole 221 is formed in the first pulley assembly 220, and the guide rod 110 is inserted into the guide hole 221. The guide hole 221 is coupled to the guide rod 110 to guide the movement of the first pulley assembly 220.
Since the first movable frame 230 has a relatively large size and weight, in order to facilitate the first movable frame 230 to move vertically better, the first movable frame 230 is provided with guide wheels 231 at two sides thereof, and two opposite inner sides of the fixed frame 100 are provided with vertically extending guide surfaces (not shown), and the guide wheels 231 abut against the guide surfaces. The guide wheel 231 is abutted with the guide surface to guide the vertical movement of the first movable frame 230, and meanwhile, the friction force during movement can be small, so that the movement process is smooth.
In addition, the rudder blade support frame 10 further includes a rudder blade holder 600, the rudder blade holder 600 includes a fixing portion 610 and an expansion portion 620, the fixing portion 610 is fixed to the first movable frame 230, the expansion portion 620 faces the horizontal direction, and the expansion portion 620 can extend to the outside of one side surface of the first movable frame 230 between the two first actuators 210. The rudder blade can be supported at different positions by changing the length of the extension part 620 extended out of the first moving frame 230, and the angle of the rudder blade can be adjusted by the mutual cooperation of the plurality of rudder blade holders 600 so as to be ready for the installation of the rudder blade.
The rudder blade support bracket 10 further includes a working surface 300, and the working surface 300 is fixed to the top end of the first moving frame 230. The rudder blade support frame 10 further includes a folding ladder 400, the folding ladder 400 is located inside the first movable frame 230, a through hole 320 is formed on the working surface 300, and one end of the folding ladder 400 is pivotally connected to an edge of the through hole 320. When the first moving frame 230 is located at the lowest point, the folding ladder 400 is in a folded state (i.e., in a horizontal position); when the first moving frame 230 moves upward, the folding ladder 400 rotates downward by gravity, so that the lower end of the folding ladder 400 approaches the fixed frame 100. In this embodiment, since the size of the fixing frame 100 itself is large, in order to facilitate the operator to climb to the top surface of the fixing frame 100, a ladder for climbing is also provided in the fixing frame 100. In order to facilitate a better operation view when the operator operates the rudder blade support frame 10, the operator may climb up the folding ladder 400 and pass through the through hole 320 and operate the rudder blade support frame 10 on the working surface 300.
In order to increase the height of the rudder blade support frame 10 that can extend when the rudder blade with a larger size needs to be supported, in this embodiment, the rudder blade support frame 10 further includes: two second actuators 510, two sets of second pulley assemblies 520, a plurality of second wires 530, and a second moving frame 540. The fixed ends of the two second drivers 510 are fixed to both sides of the first moving frame 230. Two second drivers 510 are used to drive two sets of second pulley assemblies 520 up and down. The second flexible cable 530 is embedded in the pulley of the second pulley assembly 520, and two ends of the second flexible cable 530 extend vertically downward. The working surface 300 is provided with two avoidance holes 310 penetrating in the vertical direction, the second moving frame 540 penetrates the two avoidance holes 310, the second moving frame 540 is slidably connected to the first moving frame 230, one end of the second flexible cable 530 is fixed to the first moving frame 230, and the other end of the second flexible cable 530 is fixed to the second moving frame 540.
The above-described structure is the same as the structure for lifting the first moving frame 230. In this embodiment, the pulleys of the first pulley assembly 220 and the second pulley assembly 520 are sprockets, and the first flexible cable 240 and the second flexible cable 530 are chains. The chain wheel is matched with the chain, so that the stress is large, the strength is high, and the transmission ratio is accurate.
Example 2
Fig. 5 shows a rudder blade mounting cart comprising two rudder blade supporting frames 10 described in embodiment 1, a main platform 20, a plurality of roller mechanisms 30 and two skid mechanisms 40. A plurality of roller mechanisms 30 are positioned below corners of the main platform 20 and drive the main platform 20 to move. The two sliding mechanisms 40 are slidably disposed on the main platform 20, and the two sliding mechanisms 40 are disposed opposite to each other and parallel to each other in the sliding direction. The two rudder blade supports 10 are respectively fixed on the two sliding mechanisms 40, and the two rudder blade supports 10 are arranged in a mirror image manner (not shown in the figure).
When the rudder blade is installed using the rudder blade installation cart, the rudder blade is first placed between two rudder blade support frames 10, and the position and angle of the rudder blade are adjusted and the rudder blade is fixed by adjusting the distance between the two sliding mechanisms 40, the height of the rudder blade support frame 10 rising, and the length of the extension part 620 of the rudder blade holder 600 extending. And then, the rudder blade is conveyed to the mounting position of the stern by the mobile trolley, and the rudder blade is mounted to the stern by utilizing a jacking oil cylinder on the rudder blade mounting trolley.
