Description

Technical Field

[0001] This utility model belongs to the field of marine technology, and in particular relates to a shipboard hand-cranked radar base. Background Technology

[0002] During inland waterway vessel navigation, due to the height restrictions of bridges, equipment that is too high is prone to touching the bottom of the bridge. Therefore, some marine equipment is designed to be tiltable when passing under bridges. However, this technology is wasteful of manpower, resources, and time. In addition, when the equipment is tiltable, a base plate is required when it falls, which wastes marine space and processing materials. Therefore, we designed a marine hand-cranked radar base that eliminates the need for a base plate. The radar height is changed by hand-cranking technology, so that the equipment will not touch the bottom of the bridge and ensures the safe passage of inland waterway vessels under bridges. Summary of the Invention

[0003] The purpose of this utility model is to provide a shipboard hand-cranked radar base, which eliminates the need for a base plate and uses hand-crank technology to raise and lower the radar, changing its height so that the equipment does not touch the bottom of the bridge, thus ensuring the safe passage of inland waterway vessels across the bridge, thereby solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A shipboard hand-cranked radar base includes a main square tube installed on the roof deck of the bridge. A secondary square tube is welded to the top of the main square tube. A lifting square tube is slidably connected to the inner cavity of the secondary square tube. A mounting plate is welded to the top of the lifting square tube. The bottom of the lifting square tube extends into the inner cavity of the main square tube and a pulley is fixedly installed thereon. A steel wire rope is fixedly installed on the left side of the secondary square tube. A rope winding assembly is provided on the right side of the secondary square tube. The rope winding assembly includes an inverted U-shaped plate fixedly connected to the right side of the secondary square tube. A rotatable rotating rod is provided through the inverted U-shaped plate. A winding reel is fixedly connected to the surface of the rotating rod. One end of the steel wire rope passes around the pulley and is installed on the winding reel.

[0005] Preferably, a ratchet is fixedly connected to the surface of the rotating rod, a shaft pin is fixedly connected to the front side of the inverted U-shaped plate, and a pawl that engages with the ratchet is fixedly connected to the surface of the shaft pin.

[0006] Preferably, a limiting plate is fixedly connected to the top of the inverted U-shaped plate, and a spring is installed between the inner side of the limiting plate and the top of the pawl.

[0007] Preferably, a handle is fixedly installed at the front end of the rotating rod.

[0008] Preferably, a hanging ring is fixedly connected to the end of the wire rope away from the winding reel, and an L-shaped hook is welded to the left side of the secondary square tube, with the hanging ring hooked onto the surface of the L-shaped hook.

[0009] Preferably, the end of the L-shaped hook surface is threaded with a limiting nut.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model allows the lifting square tube to slide up and down within the inner cavity of the secondary square tube by operating the forward and reverse rotation of the lever, thereby adjusting the height of the mounting plate and the radar on the mounting plate, ensuring that the highest point of the ship will not touch the bottom of the bridge and that the ship can pass through the bridge safely; the radar height adjustment can adjust the monitoring range to ensure that there are no blind spots in the monitoring range and that the ship can sail safely. At the same time, the elimination of the pad base can save ship space and processing materials, and greatly reduce manpower, material resources and time costs.

[0012] 2. By setting a limiting nut, this utility model can limit the hanging ring after it is placed on the surface of the L-shaped hook, and effectively prevent the hanging ring from detaching from the surface of the L-shaped hook.

[0013] 3. By using the combination of the limiting plate and the spring, this utility model enables the pawl to rotate clockwise, ensuring that the pawl can always be engaged with the ratchet, effectively preventing the ratchet and the rotating rod from rotating counterclockwise, and ensuring that the wire rope is in a stable state.

[0021] In the following description, embodiments of the shipborne hand-cranked radar base of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates a shipboard hand-cranked radar base according to an embodiment of the present invention. It includes a main square tube 1 mounted on the deck of the bridge roof. A secondary square tube 2 is welded to the top of the main square tube 1. A lifting square tube 3 is slidably connected to the inner cavity of the secondary square tube 2. A mounting plate 4 is welded to the top of the lifting square tube 3. The bottom of the lifting square tube 3 extends into the inner cavity of the main square tube 1 and is fixedly mounted with a pulley 5. A steel wire rope 6 is fixedly mounted on the left side of the secondary square tube 2. A rope winding assembly 7 is provided on the right side of the secondary square tube 2. The rope winding assembly 7 includes an inverted U-shaped plate 71 fixedly connected to the right side of the secondary square tube 2. A rotatable rotating rod 72 passes through the inverted U-shaped plate 71. A winding reel 73 is fixedly connected to the surface of the rotating rod 72. One end of the steel wire rope 6 passes around the pulley 5 and is mounted on the winding reel 73. A ratchet 74 is fixedly connected to the surface of the rotating rod 72. A pivot pin 75 is fixedly connected to the front side of the inverted U-shaped plate 71. A pawl that engages with the ratchet 74 is fixedly connected to the surface of the pivot pin 75. 76. A limiting plate 77 is fixedly connected to the top of the inverted U-shaped plate 71. A spring 78 is installed between the inner side of the limiting plate 77 and the top of the pawl 76. Through the cooperation of the limiting plate 77 and the spring 78, the pawl 76 can be made to rotate clockwise, ensuring that the pawl 76 can always be engaged with the ratchet 74, effectively preventing the ratchet 74 and the rotating rod 72 from rotating counterclockwise, and ensuring that the wire rope 6 is in a stable state. A handle is fixedly installed at the front end of the rotating rod 72. Hand 79, the end of the wire rope 6 away from the winding reel 73 is fixedly connected to a hanging ring 8, and an L-shaped hook 9 is welded to the left side of the sub-square tube 2. The hanging ring 8 is hooked onto the surface of the L-shaped hook 9. The end of the surface of the L-shaped hook 9 is threadedly connected to a limiting nut 10. By setting the limiting nut 10, after the hanging ring 8 is put on the surface of the L-shaped hook 9, the limiting nut 10 is screwed on the surface of the L-shaped hook 9, which can limit the hanging ring 8 and effectively prevent the hanging ring 8 from detaching from the surface of the L-shaped hook 9.

[0023] Working principle: When using this utility model, the main square tube 1 is installed on the roof deck of the driver's cab, and then the radar can be installed on the mounting plate 4. By turning the handle 79 clockwise, the handle 79 drives the rotating rod 72 and the winding reel 73 to rotate, so that the winding reel 73 winds up the wire rope 6. The wound wire rope 6 drives the pulley 5 to rotate, and the pulley 5 will rise, thereby driving the lifting square tube 3 to rise. The lifting square tube 3 then drives the radar to rise through the mounting plate 4. During this process, the ratchet 74 will rotate with the rotation of the rotating rod 72. The pawl 76 will be engaged with the ratchet 74 by the spring 78, which restricts the counterclockwise rotation of the ratchet 74 and the winding reel 73. When the radar needs to be lowered, simply turn the shaft pin 75 counterclockwise to drive the pawl 76 to rotate counterclockwise, so that the pawl 76 is disengaged from the ratchet 74. The weight of the lifting square tube 3 will cause the winding reel 73 to unwind, so that the lifting square tube 3 drives the mounting plate 4 to descend.

[0024] In summary: This vessel uses a hand-cranked radar base. By operating the rotating rod 72 in both forward and reverse directions, the lifting square tube 3 slides up and down within the inner cavity of the secondary square tube 2, thereby adjusting the height of the mounting plate 4 and the radar on the mounting plate 4. This ensures that the highest point of the vessel will not touch the bottom of the bridge, allowing for safe passage under the bridge. The radar height adjustment allows for adjustment of the monitoring range, ensuring that there are no blind spots in the monitoring range and safe navigation. At the same time, eliminating the need for a base plate saves ship space and processing materials, greatly reducing manpower, material resources, and time costs.
