Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] To ensure the lifting equipment has a protective structure during use, effectively preventing the lifting beam from falling in the event of a failure in the lifting drive structure, and thus improving safety during operation, such as... Figures 1-5As shown, the present invention discloses a ship lifting equipment with a protective structure, comprising a lifting mechanism 100, a protective mechanism 200, and a limiting ring 210. The lifting mechanism 100 consists of a base A101, a vertical beam 102, an electric hydraulic cylinder 113, and a horizontal beam 104. One bottom end of the horizontal beam 104 is connected to a hook 108 via a chain 107. One side of the bottom end of the vertical beam 102 is rotatably connected to the electric hydraulic cylinder 113 via a hinge point C112. One end of the horizontal beam 104 is rotatably connected to the top end of the vertical beam 102 via a hinge point A103. One bottom end of the horizontal beam 104 is connected to the power output end of the electric hydraulic cylinder 113 via a hinge point B110.

[0029] The protective mechanism 200 includes a base B201, a mounting bracket 202 on the top of the base B201, an extension plate 205 near the bottom on one side of the mounting bracket 202, a brake motor 206 mounted on the top side of the extension plate 205 via a fixed seat, a vertical plate 207 welded to the other side of the top of the limiting ring 210, a coupling 208 mounted on one side of the vertical plate 207 via screws, a guide wheel 203 and a take-up reel 204 mounted on the inner side of the mounting bracket 202 via a rotating shaft, one end of the coupling 208 connected to the rotating shaft of the take-up reel 204 via a key, and the other end of the coupling 208 connected to the output shaft of the brake motor 206 via a key, a lifting ring 111 welded to the top end of the crossbeam 104, and a steel wire rope 209 wound around the outer periphery of the take-up reel 204, one end of the steel wire rope 209 passing outside the guide wheel 203 and connected to the lifting ring 111.

[0030] In use, the electric hydraulic cylinder 113, hinge point B110, hinge point A103, and crossbeam 104 are connected to the hinge point C112, the electric hydraulic cylinder 113 drives the crossbeam 104 to rotate around the hinge point A103, and the lifting of the item is completed through the chain 107 and the hook 108. The brake motor 206 and the electric hydraulic cylinder 113 are both connected to an external PLC controller for control. When the electric hydraulic cylinder 113 drives the crossbeam 104 to descend, the brake motor 206 drives the take-up reel 204 to rotate, releasing the wire rope 209. The length of the released rope is equal to the length required for the crossbeam 104 to descend. When the crossbeam 104 rises, the wire rope 209 is wound up synchronously, and the wire rope 209 is always in a taut state.

[0031] For example, such as Figure 1 As shown, the present invention also includes a vertical block 105 provided on the top of the crossbeam 104, and a strip reinforcing plate 106 welded between the vertical block 105 and the crossbeam 104.

[0032] When in use, the strip reinforcing plate 106 can effectively improve the overall strength of the crossbeam 104 and enhance the stability of the crossbeam 104 under stress.

[0033] For example, such as Figure 1 and Figure 5 As shown, the present invention also includes a counterweight mechanism 300 welded to one end of the vertical beam 102 near the top. The counterweight mechanism 300 is composed of an L-shaped sleeve shaft 301, a sleeve 302 and a fixing pin 303. The L-shaped sleeve shaft 301 is sleeved inside the sleeve 302.

[0034] During use, the L-shaped sleeve 301 can be pre-fixed using the sleeve 302.

[0035] For example, such as Figure 1 and Figure 5 As shown, the present invention also includes an external thread on the outer periphery of the bottom end of the L-shaped sleeve shaft 301, and a pin hole through which a pin is opened at the top of the L-shaped sleeve shaft 301 near the sleeve 302, and a fixing pin 303 is provided in the pin hole.

[0036] In use, by opening a threaded hole on the external counterweight block, and using the threaded hole to engage with the external thread on the bottom periphery of the L-shaped sleeve shaft 301, the external counterweight block can be easily fixed to the bottom of the L-shaped sleeve shaft 301. The counterweight block can be used to facilitate the counterweighting of the lifting mechanism 100. The fixing pin 303 can be used to effectively limit the position of the sleeve 302 inside the L-shaped sleeve shaft 301.

[0037] For example, such as Figure 4 As shown, the present invention also includes a limit ring 210 welded to one side of the outer periphery of the take-up reel 204.

[0038] During use, the limiting ring 210 can be used to easily fix one end of the yarn wound around the take-up reel 204.

[0039] For example, such as Figure 1 and Figure 3 As shown, the present invention also includes connecting plates 109 provided at the bottom of the vertical beam 102 and the top of the base A101, and the connecting plates 109 are fastened together by bolts.

[0040] During use, the two sets of connecting discs 109 can be easily locked and fixed with bolts, thereby connecting and fixing the vertical beam 102 and the base A101.

[0041] For example, such as Figure 1 and Figure 3 As shown, the present invention also includes mounting holes through the bottom of both the base A101 and the base B201, and a reinforcing rib is provided at the bottom corner of the base A101.

[0042] In use, the lifting mechanism 100 and the protective mechanism 200 can be installed on the deck of the ship by passing external bolts through the mounting holes.

[0043] For example, such as Figure 1 and Figure 2 As shown, the present invention also includes a ceramic wear-resistant layer on the outer surface of both the guide wheel 203 and the take-up wheel 204.

[0044] During use, the ceramic wear-resistant layer can effectively extend the service life of the guide wheel 203 and the take-up wheel 204.

[0045] In use, the lifting mechanism 100 and the protective mechanism 200 can be installed on the deck of a ship by passing external bolts through the mounting holes, thus installing the lifting equipment on the ship. Through the hinge point C112, the electric hydraulic cylinder 113, the hinge point B110, the hinge point A103 and the crossbeam 104, the electric hydraulic cylinder 113 drives the crossbeam 104 to rotate around the hinge point A103 when working. The chain 107 and the hook 108 at the bottom end of the crossbeam 104 cooperate with the preset lifting point on the top of the item to complete the lifting work of the item.

[0046] Both the brake motor 206 and the electric hydraulic cylinder 113 are connected to an external PLC controller for control. When the electric hydraulic cylinder 113 drives the crossbeam 104 to descend, the brake motor 206 drives the take-up reel 204 to rotate, releasing the wire rope 209. The length of the released rope is equal to the length required for the crossbeam 104 to descend. When the crossbeam 104 rises, the wire rope 209 is simultaneously wound up, and the wire rope 209 is always taut. If the electric hydraulic cylinder 113 fails unexpectedly, the brake motor 206 has a built-in brake, and its output shaft has a holding function, and the wire rope 209 is always taut. The wire rope 209 can be used to brake the fall of the crossbeam 104. This lifting equipment has a protective structure, which can effectively prevent the lifting beam from falling when the lifting drive structure fails, greatly improving the safety effect during operation.
