Description

Technical Field

[0001] The utility model relates to a hoisting tool, in particular to a hoisting tool which is easy to assemble and belongs to the technical field of underwater vehicle hoisting equipment. Background Art

[0002] Generally speaking, an underwater vehicle is a vehicle that sails underwater, including manned underwater vehicles and unmanned underwater vehicles. It can complete underwater exploration, detection and even military offensive and defensive tasks. When an underwater vehicle is inspected and repaired, it needs to be lifted from underwater, which requires a lifting tool.

[0003] After searching, the Chinese utility model patent with the announcement number CN210710320U discloses a lifting tool, which relates to the field of lifting and hoisting. It includes a main lifting beam, a main lifting eye, an adjusting screw, a movable lifting eye, and at least four connecting parts. The main lifting beam is used to carry the suspended object, and the main lifting eye is set on the main lifting beam for connecting to the crane hook. The adjusting screw is set on the main lifting beam and is parallel to the main lifting beam. The movable lifting eye is set on the adjusting screw and is connected to the adjusting screw by a thread. The connecting part has a connecting screw and a lifting part, and the connecting screw is connected to the through hole of the movable lifting eye. The lifting part is used for detachable connection with the suspended object. It is easy to use and can realize the lifting and transportation of different objects. It has the function of adjusting the distance of the suspension points, realizing the selection of different suspension points for objects of different lengths. The tooth pattern can prevent the sliding of the connecting sleeve during the lifting process. However, the lifting tool is to adjust the distance between the hanging points to achieve the selection of different hanging points for objects of different lengths. However, different hanging points will cause the center of gravity to shift, which is prone to tipping and poses a safety hazard, and cannot well meet people's usage needs.

[0053] Finally, the operator releases the pull ring (46), the first spring (47) rebounds the locking plate (45), and the block (44) meshes with the lower part of the gear (43). At this time, the upper part of the gear (43) and the rack (12) are fixed in position, thereby preventing tipping during the lifting process. When lifting, the two hangers (22) increase the force-bearing area during lifting, making it more balanced, thereby improving safety.

[0114] The gear 43 is located in the slide groove 11 , and the lower end of the gear 43 passes through the lower part of the load-bearing rod 1 .

[0115] In the present invention, the lower portion of the gear 43 passes through the slide slot 11 and is located outside the load-bearing rod 1 .

[0116] More specifically, Figure 8 and Figure 9 As shown, the locking assembly includes:

[0117] A clamping block 44 is provided with a clamping tooth adapted to the gear 43 and is connected to the top of the locking plate 45;

[0124] A connecting cable 52 is provided, one end of which is connected to the connecting buckle 51 , and the other end of the connecting cable 52 is hingedly connected to the hanging net 6 .

[0125] In the present invention, the four corners of the hanging net 6 are respectively hingedly connected to the corresponding connecting cables 52, which disperses the force during hanging and makes the hanging more stable.

[0126] Specifically, such as Figure 11 As shown, the connecting buckle 51 includes:

[0127] A connecting buckle body 511, wherein one side of the connecting buckle body 511 is provided with an opening;

[0132] In summary, the more specific implementation methods of the present invention are:

[0133] Before using the lifting tool with the above-mentioned design structure which is easy to assemble, the operator only needs to carry the utility model to the designated working position through corresponding carrying equipment or directly by hand to wait for use.

[0134] When in use, the operator first inserts the two ends of the load-bearing rod 1 into the mounting block 21, and then inserts the latch 32 into the latch holes at both ends of the load-bearing rod 1. The limiting ring 31 and the latch 32 limit the position of the mounting block 21 to prevent displacement, thus completing the assembly of the tooling body;

[0135] Then, the operator presses the buckle 512, hooks the connecting buckle body 511 onto the hook ring 23, releases the buckle 512, and rebounds under the elastic action of the second spring 514. The telescopic rod 513 resets the buckle 512 under the elastic action of the second spring 514, and the buckle 512 and the connecting buckle body 511 form a closed ring. The same operation is used to complete the combination of two connecting assemblies 5 on the same hanger 22;

[0136] Next, the operator lowers the tooling into the water, catches the bottom of the underwater vehicle 8 with the hanging net 6, and then locks the connecting components 5 on the other two connecting cables 52 to the hooks 23 under another hanger 22;

[0137] Then, the operator connects the lifting end of the crane to the lifting ring 41, and pulls the pull ring 46, thereby contracting the first spring 47, releasing the lock between the block 44 connected to the upper part of the locking plate 45 and the gear 43. The operator moves the pull ring 46 and drives the connected slider 42 to move along the slide groove 11. At the same time, the slider 42 drives the gear 43 to move on the rack 12, thereby effectively adjusting the position of the balancing assembly 4 to the center of gravity of the underwater vehicle 8.

[0138] Finally, the operator releases the pull ring 46, the first spring 47 bounces the locking plate 45 back, and the block 44 engages with the lower part of the gear 43. At this time, the upper part of the gear 43 is fixed to the position of the rack 12, thereby preventing tipping during the lifting process. When lifting, the two hangers 22 increase the force area during lifting, which is more balanced, thereby improving safety.

[0139] During the above-mentioned use, when the water in the water area is turbid or the lighting conditions are poor at night, the operator can turn on the waterproof light 7 to assist in locking the connecting component 5, thereby improving work efficiency, facilitating the assembly of the lifting tooling, and facilitating the installation and disassembly of the underwater hanging net 6.

[0140] Specifically, a slide groove 11 is opened below the load-bearing rod 1, and the balancing assembly 4 is arranged in the slide groove 11. The balancing assembly 4 includes a rack 12, a gear 43, a locking plate 45, a pull ring 46, a first spring 47 and a slider 42. The gear 43 is meshed below the rack 12, and the locking plate 45 is embedded below the gear 43. A pull ring 46 is welded below the locking plate 45, and the outer periphery of the pull ring 46 is wrapped with the first spring 47, and the outer periphery of the first spring 47 is wrapped with the slider 42.

[0141] Furthermore, the outer peripheries of the left and right ends of the load-bearing rod 1 are both wrapped with mounting blocks 21 , and the left and right ends of the load-bearing rod 1 are both inlaid with latches 32 .

[0142] Specifically, a hanger 22 is welded below the mounting block 21 , and hooks 23 are welded below both the front and rear ends of the hanger 22 , and a waterproof lamp 7 is mounted inside the hook 23 .

[0143] Specifically, a connecting component 5 is hinged below the hook ring 23 , and the connecting component 5 includes a connecting buckle 51 and a connecting cable 52 . The connecting buckle 51 includes a connecting buckle body 511 and a buckle 512 . The buckle 512 is hinged on the right side of the connecting buckle body 511 .

[0144] Specifically, the connecting buckle 51 further includes a telescopic rod 513 and a second spring 514 . The telescopic rod 513 is hinged at the lower part of the inner portion of the connecting buckle body 511 , and the second spring 514 is wrapped around the outer portion of the telescopic rod 513 .

[0145] Specifically, a connecting cable 52 is installed below the connecting buckle body 511 , and a hanging net 6 is hinged below the connecting cable 52 .

[0146] Furthermore, the load-bearing rods 1 at both ends of the slider 42 are provided with limit rings 31 , and a hanging ring 41 is welded above the slider 42 .

[0147] In summary, the advantages of the present invention in the specific implementation are:
