Technical Field

[0001] The utility model relates to the field of ship maintenance, in particular to an equipment crane for ship maintenance. Background Art

[0002] Cranes are widely used to lift equipment during ship maintenance. Ships refer to various vessels and water vehicles used for water transportation, operations, or other activities. Depending on their purpose, ships can be divided into many categories, such as cargo ships, passenger ships, fishing vessels, patrol boats, warships, and yachts. The design and construction of ships must take into account the waters in which they sail, their load capacity, speed, safety, and ability to adapt to various weather conditions. Cranes are also used in ship maintenance.

[0020] The utility model has the following beneficial effects:

[0021] In the utility model, first, through the first mounting seat, the second mounting seat, the connecting block, the first support rod, and the spring, the nut pair is rotated to drive the threaded rod to move, so that the positioning block can be moved away from the positioning groove, releasing the limit on the first support rod, and then the first support rod can be pulled to move the protrusion out of the limit groove. During the movement, the spring will be squeezed to disassemble the crane body. When installing, the first support rod is pulled to drive the positioning groove to move, and the connecting block is placed in the first mounting seat. The first support rod is loosened, the spring rebounds, and the protrusion limits the connecting block. Then the nut pair is rotated again to fix the positioning block to the first support rod, thereby preventing accidental collision, facilitating installation and disassembly, and thus facilitating transportation.

[0030] Reference Figures 1-4The utility model provides an embodiment of a ship maintenance equipment crane, comprising a support rod 1, the top of the support rod 1 is fixedly connected to a first mounting seat 4, the top of the first mounting seat 4 is provided with a second mounting seat 5, and the bottom of the second mounting seat 5 is fixedly connected to a connecting block 7, and then the connecting block 7 can be separated from the first mounting seat 4 for disassembly, which is convenient for transportation and improves the practicality of the crane. When the equipment crane is used, the positioning slot 10 is pulled to move the protrusion 11, and limiting slots 8 are provided at the left and right ends of the connecting block 7. The left and right ends of the first mounting seat 4 are penetrated and fixedly connected with a fixing ring 9, and the inner ring of the fixing ring 9 is slidably connected with a first support rod 12, and then the first support rod 12 slides in the fixing ring 9 and squeezes the spring 13. At the same time, when the connecting block 7 is placed in the first mounting seat 4, the first support rod 12 can be released, the spring 13 rebounds, and then the protrusion 1 1 enters the limiting groove 8, the outer ring of the first support rod 12 is sleeved with a spring 13, one end of the first support rod 12 is fixedly connected to the protrusion 11, the rear sides of the left and right ends of the outer wall of the first mounting seat 4 are fixedly connected to the L-shaped plates 14, the opposite sides of the two L-shaped plates 14 are fixedly connected to the second support rod 15, and one side of the two second support rods 15 is rotatably connected to the nut pair 20. When the equipment crane needs to be transported, the nut pair 20 can be manually rotated to drive the threaded rod 21 to rotate in the second support rod 15, and then drive the fixed block 6 to move. The slider 17 slides within the slide rail 16 to limit the positioning block 18, and the inner rings of the two nut pairs 20 are threadedly connected to the threaded rod 21. One side of the two threaded rods 21 is rotatably connected to the fixed block 6. The front ends of the two fixed blocks 6 are fixedly connected to the connecting rod 19, and one side of the outer rings of the two connecting rods 19 is fixedly connected to the positioning block 18.

[0031] The outer ring of the support rod 1 is fixedly connected to a reinforcement seat 2, and the front sides of the left and right ends of the first mounting seat 4 are fixedly connected to slide rails 16, and the inner walls of the slide rails 16 are slidably connected to sliders 17, which are fixedly connected to the connecting rod 19, and the protrusions 11 are engaged with the limiting grooves 8. A crane body 3 is provided on the top of the second mounting seat 5, and a connecting block 7 is slidably connected to the inner wall of the first mounting seat 4. In order to prevent the first support rod 12 from displacement, the nut pair 20 is then rotated to drive the threaded rod 21 to extend, and then the positioning block 18 will enter the positioning groove 10 to position the first support rod 12 and play a stabilizing role. The other end of the first support rod 12 is provided with a positioning groove 10, and then the positioning groove 10 can be pulled to drive the first support rod 12 to slide in the fixing ring 9, and then the protrusion 11 is moved out of the limiting groove 8 and squeezes the spring 13, and the positioning groove 10 is engaged with the positioning block 18, and a spring 13 is provided between the protrusion 11 and the fixing ring 9.

[0032] Working principle: When the equipment crane needs to be transported, the nut pair 20 can be manually turned to drive the threaded rod 21 to rotate in the second support rod 15, and then the fixed block 6 can be moved. The slider 17 slides within the slide rail 16 to limit the positioning block 18 away from the positioning groove 10 for separation. Then, the positioning groove 10 can be pulled to drive the first support rod 12 to slide in the fixing ring 9. Then the protrusion 11 is moved out of the limiting groove 8 and the spring 13 is squeezed. Then, the connecting block 7 can be separated from the first mounting seat 4 for disassembly, which is convenient for transportation and improves the crane's performance. Practicality: When using the equipment crane, pull the positioning groove 10 to move the protrusion 11, and then the first support rod 12 slides in the fixing ring 9 and squeezes the spring 13. At the same time, when the connecting block 7 is placed in the first mounting seat 4, the first support rod 12 can be loosened, the spring 13 rebounds, and then the protrusion 11 enters the limiting groove 8 to limit the connecting block 7. In order to prevent the first support rod 12 from displacement, the nut pair 20 is then rotated to drive the threaded rod 21 to extend, and then the positioning block 18 will enter the positioning groove 10 to position the first support rod 12 and play a stabilizing role.
