[0036] A vacuum anchor is a device fixed to the shore of a dock for a ship to dock. Part of the vacuum anchor is located on the sea surface. When the device needs to be repaired, the operator may need to perform operations on the sea side, which is not convenient for the operator to perform repair operations, has poor safety, and the device cannot be repaired when the ship is docked.

[0037] To solve the above technical problems, an embodiment of the present invention provides a rotatable vacuum anchor device. The vacuum anchor device uses a rotating assembly to rotate the part to be repaired to the shore so that the operator can repair it on the shore, improving the convenience and safety of the operator's repair, and the docking of the ship is not affected when the operator repairs one of the vacuum anchors.

[0038] First, a rotatable vacuum anchor device according to an embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

[0039] Specifically, as Figure 1 and Figure 2 shown, a rotatable vacuum anchor device 100 provided by an embodiment of the present invention includes a base 10, a rotating assembly 20, and a vacuum adsorption assembly 30.

[0040] Among them, the base 10 is used for fixed installation on the shore 200. The rotating assembly 20 is installed on the base 10 and can perform a rotating motion. The vacuum adsorption assembly 30 is used for adsorbing on the surface of the ship. The vacuum adsorption assembly 30 is installed on the rotating assembly 20, and the rotating assembly 20 rotates so that the part to be repaired on the vacuum anchor device 100 faces the shore 200.

[0041] That is to say, the rotating assembly 20 is installed on the base 10. When the part to be repaired faces the sea side, the rotating assembly 20 is used to perform a rotating motion so that the part to be repaired rotates to face the land side, facilitating the operator to repair it on the shore, and other vacuum anchor devices 100 installed on the shore 200 can also be used for the docking operation of the ship.

[0042] In an embodiment, as Figure 3 and Figure 4As shown, the rotating assembly 20 includes a slewing bearing 220 and a slewing base plate 210. The base 10 is fixedly connected to the inner ring 222 of the slewing bearing 220, and the slewing base plate 210 is fixedly connected to the outer ring 221 of the slewing bearing 220. The outer ring 221 of the slewing bearing 220 can rotate relative to the inner ring 222 of the slewing bearing 220. The slewing bearing 220 can bear large axial loads, radial loads, overturning moments and other loads, improving the stability of the vacuum anchor device 100. The base 10 includes a base top plate 110, and the inner ring 222 of the slewing bearing 220 is fixedly connected to the base top plate 110.

The slewing base plate 210 and the outer ring 221 of the slewing bearing 220 are fixedly connected through the connecting bolts 230, and the base 10 is fixedly connected to the inner ring 222 of the slewing bearing 220 through the connecting bolts 230. The connecting bolts 230 are simple in structure and convenient to operate.

[0044] In one embodiment, as Figure 5 and Figure 6 shown, the vacuum anchor device 100 further includes a locking assembly 60. The locking assembly 60 includes a plurality of locking members 610, and the plurality of locking members 610 are used to fixedly connect or movably connect the base 10 and the slewing base plate 210. The locking members 610 are preferably bolts, but are not limited thereto. Bolts are convenient for disassembly and installation, improving the convenience of switching between locking operations and rotating operations.

[0045] In one embodiment, as Figure 5 shown, the vacuum anchor device 100 further includes a maintenance fixing assembly. The maintenance fixing assembly is used to fix the rotating assembly 20 and the base 10 in the maintenance state of the vacuum anchor device 100. The maintenance fixing assembly includes a fixing seat 710, a fixing rod 720 and a plurality of fixing grooves. The fixing rod 720 is detachably installed on the fixing seat 710. The fixing seat 710 is fixedly installed on the slewing base plate 210. The fixing grooves are installed on the base 10. The fixing rod 720 matches the fixing grooves and can make the slewing base plate 210 and the base 10 relatively stationary.

[0046] That is to say, when the part to be repaired rotates towards the land side, in order to facilitate the operation of the operator and improve the safety of the operator, the rotating assembly 20 is temporarily fixed. That is, by inserting the fixing rod 720 into the fixing groove on the base 10, the slewing base and the base 10 are relatively stationary during maintenance.

[0047] Further, the repair and fixing assembly further includes a first limiting block 730 and a second limiting block 740. The first limiting block 730 and the second limiting block 740 are convexly installed on the surface of the base 10, and the fixing groove is formed between the first limiting block 730 and the second limiting block 740. The fixing groove in this embodiment meets the use requirements and has a simple structure.

[0048] In one embodiment, as Figure 1 and Figure 2 shown, the vacuum anchor device 100 further includes a support assembly 40. The support assembly 40 includes a support base 410 and a mounting member 420.

Preferably, the mounting member 420 is installed on the support base 410 by means of pin connection, but of course it is not limited to this.

[0049] Further, as Figure 2 and Figure 7 shown, the vacuum anchor device 100 further includes an adjustment assembly. The adjustment assembly includes a horizontal hydraulic adjuster 510, a pitching hydraulic adjuster 520 and a hydraulic station 530. The horizontal hydraulic adjuster 510 and the pitching hydraulic adjuster 520 are both connected to the hydraulic station 530.

[0050] The horizontal hydraulic adjuster 510 is installed in the mounting member 420 and connected to the vacuum adsorption assembly 30. The vacuum adsorption assembly 30 reciprocates horizontally under the action of the horizontal hydraulic adjuster 510.

[0051] The end of the pitching hydraulic adjuster 520 is fixedly connected to the bottom of the mounting member 420 close to the vacuum adsorption assembly 30. The vacuum adsorption assembly 30 follows the mounting member 420 to perform up and down heaving around the support base 410 under the action of the pitching hydraulic adjuster 520.

[0052] The vacuum adsorption assembly 30 includes an adsorption head and a vacuum generating member. The adsorption head is used to adsorb on the ship surface. After the adsorption head adsorbs on the ship surface, the horizontal hydraulic adjuster 510 and the pitching hydraulic adjuster 520 are used to adjust the position of the adsorption head to further adjust the docking position of the ship.

[0053] The horizontal hydraulic adjuster 510 and the pitching hydraulic adjuster 520 are used to adjust the position of the adsorption head, improving the adjustment accuracy of the ship attitude and further improving the efficiency of the ship docking at the shore 200.

[0054] In one embodiment, asFigure 1 and Figure 7 As shown in Figure 7 , the vacuum anchor device 100 further includes a safety support rod 80. One end of the safety support rod 80 is movably installed on the rotary bottom plate 210, and the other end can abut against the bottom of the mounting member 420. When the vacuum anchor device 100 is not performing ship docking operations, the safety support rod 80 is used to support the bottom of one end of the mounting member 420, improving the stability and firmness of the vacuum anchor device 100.

[0055] In one embodiment, as Figure 2 shown in Figure 2 , the support base 410 is provided with a mounting hole; the vacuum anchor device 100 further includes a rotary operating rod 50. The rotary operating rod 50 is inserted into the mounting hole to use the rotary operating rod 50 to push the rotating assembly 20 to rotate relative to the base 10.

[0056] The rotary operating rod 50 is inserted into the mounting hole, facilitating the operator to push the rotating assembly 20 to perform a rotating motion.

[0057] Furthermore, mounting holes are provided on both sides of the support base 410. The rotary operating rods 50 are inserted into both sides of the support base 410, and two operators act on the rotary operating rods 50 to improve the rotation efficiency of the rotating assembly 20.

[0058] The rotary operating rod 50 is preferably a hollow circular tube, although it is not limited thereto. The rotary operating rod 50 with a hollow circular tube structure is convenient for the operator to pick up or place.

[0059] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
