Description

Technical Field

[0001] The invention relates to the technical field of cranes, and in particular to a hull structure hoisting device and a hoisting method that are easy to install and use. Background Art

[0002] Cantilever cranes are small and medium-sized lifting equipment developed in recent years. They have unique structures, are safe and reliable, and have the characteristics of high efficiency, energy saving, time and labor saving, and flexibility. Therefore, cantilever cranes are used more and more widely, such as lifting ship structures.

[0003] The publication number is CN220300254U, which is a cantilever crane that is easy to position and install. The problem raised in the background technology is that the existing cantilever crane takes a lot of time to install and disassemble, which makes it inconvenient to use; The background technology of the anti-overturning device for a running cantilever crane with the publication number CN115072579B raises the following problem: there is no anti-overturning device specifically used for cantilever cranes in the prior art, and the cantilever crane cannot be effectively prevented from overturning.

[0004] Based on the existing technology, there are the following problems: In the existing cantilever crane, the column and the like are usually installed at a specified position through a base, and the base is fixed to the specified ground through bolts and the like. Therefore, when adjusting the lifting position, it is necessary to disassemble and install the bolts and the like to adjust the position of the cantilever crane, which is relatively cumbersome. In addition, the cantilever crane usually has the object to be hoisted located on one side of the column, which leads to a large difference in the force on both sides of the column, and is prone to tipping. There are installation hazards while reducing the weight of the hoisting. Referring to the above application documents, although it is convenient to position and install the cantilever crane, it is limited to installing the cantilever crane on the wall, and the installation position is limited. Although it can prevent the cantilever crane from tipping over, the top and bottom of the column are connected to the cross column at the top, so that the force is more uneven, and the anti-tip-over effect is poor. Alternatively, the cantilever crane is designed to be a gantry, which occupies the lifting space and affects the actual lifting use. There are certain shortcomings. In order to solve the above problems, a hull structure lifting device and a lifting method that are easy to install and use are proposed. Summary of the invention

[0031] In a specific implementation, after the bottom of the column 2 contacts the top of the base 1, the bottom of the pressure ring 732 contacts the top of the retaining ring 731, so that the side wall of the pressure ring 732 contacts the inner wall of the annular groove 736, so as to limit the connection between the column 2 and the base 1 from the side, thereby reducing the probability of the column 2 tipping over during the subsequent lifting process, and under the action of the second spring, the bottom of the pressure ring 732 is tightly attached to the top of the retaining ring 731, so that in the process of lifting the hull mechanism, the weight of the hoisted object acts on the cross column 5 during the actual lifting process of the cantilever crane, and the cross column 5 is located on one side of the column 2, thereby causing the column 2 to deflect, so that the force acting on the base 1 by the column 2 Changes occur, such as an increase in the force acting on the base 1 in the direction of the heavy object. At this time, by setting up pressure sensors 737 arranged in a circular array, it is convenient to actually grasp the changes in the force acting on the base 1 by the column 2, so as to hoist the hull mechanism according to the actual weight borne by the column 2 to avoid tipping. Compared with the traditional installation of tension sensors at the position of the hoisting component 6 to monitor the weight of the pulled object to determine whether the column 2 has tipped, it directly acts on the column 2, which is convenient for warning the bearing range of the column 2. After the traditional hoisting of the object, the position of the object on the horizontal column 5, that is, the distance of the object from the column 2 changes, the force acting on the column 2 will also change, thereby affecting the monitoring effect; The bearing range of the column 2 is controlled by the second limit assembly 73, so that it can be adjusted according to the weight of the hoisted object and through the anti-dumping assembly, thereby facilitating the adjustment of the hoisting weight and facilitating actual hoisting use.

[0034] In the specific implementation, after the column 2 is installed on the top of the base 1, the clamping plate 316 is inserted into the connecting groove 3292 along the top of the connecting piece 322, so as to connect the first connecting component 32 and the second connecting component 31, so that the cross column 5 is connected to the base 1, so that when the hull structure is hoisted, the cross column 5 is limited away from the hull structure, thereby improving the stability of both sides of the column 2 and reducing the probability of tipping, and the connecting piece 322 is rotatably connected to the base 1 through the annular groove and the annular slider 321, so that the connecting piece 322 is driven to rotate during the rotation of the cross column 5, so that the anti-tipping mechanism 3 and the cross column 5 are always arranged horizontally, and are respectively located on both sides of the column 2, further improving the anti-tipping effect; The second locking plate 326 is locked by the locking cam 328, so that the locking cam 328 can be locked to the locking cam 329, thereby locking the locking cam 329 in the locking cam 329. The first connecting plate 318 is hinged to the fixing member 311 through the hinge 312, and the clamping plate 316 is hinged to the second connecting plate 314, so as to facilitate adjustment of the angle of the first connecting plate 318 and the second connecting plate 314, and the spacing between the first connecting plate 318 and the second connecting plate 314 is adjusted through the second threaded rod 313, so as to facilitate adjustment of the position of the clamping plate 316 inserted into the connecting groove 3292, so as to facilitate adjustment according to the space size of the hoisting environment, and facilitate actual anti-dumping use, and the positions of the first fixing block 324, the second fixing block 325 and the anti-drop assembly 323 are adjusted through the third threaded rod 327 to ensure the stability of the connection between the clamping plate 316 and the connecting member 322 at different positions; Since the second threaded rod 313 is rotatably connected to the second connecting plate 314, the first connecting plate 318 and the second connecting plate 314 do not deflect when the distance between the first connecting plate 318 and the second connecting plate 314 is adjusted by the second threaded rod 313, so as to avoid affecting the insertion of the clamping plate 316 into the connecting groove 3292; By making the bottom of the clamping plate 316 inclined and the top inner wall of the connecting groove 3292 arc-shaped, the smoothness of the clamping plate 316 entering the connecting groove 3292 is improved, which is convenient for actual connection and use.

[0035] See also Fig.16 , the anti-drop assembly 323 comprises: The shell 3231 is fixed on the top of the fixing plate 326 and extends into the second fixing block 325. The inner wall of the shell 3231 is sleeved with a ring body 3233. The inner wall of the ring body 3233 is fixedly sleeved with a rod body 3232 extending to the bottom of the second fixing block 325 so that the rod body 3232 can be inserted into the groove 317. The top of the rod body 3232 extends to the top of the shell 3231. A pull plate is fixedly provided at one end of the rod body 3232 located at the top of the shell 3231. A third through hole extending to the bottom of the second fixing block 325 and used for sleeved with the rod body 3232 is opened at the top of the shell 3231.

A third spring is sleeved on the side wall of one end of the rod body 3232 located in the shell 3231 and located at the top of the ring body 3233.

[0036] In a specific implementation, after the clamping plate 316 is inserted into the connecting groove 3292, the pull plate is pulled upward, and the pull plate drives the rod body 3232 and the ring body 3233 to compress the third spring and move upward. After the fixing plate 326 moves to the top of the clamping plate 316, the pull plate is released, and the rod body 3232 is inserted into the abutting groove 317 under the action of the third spring, thereby limiting the clamping plate 316 to prevent the clamping plate 316 from being separated from the connecting member 322 along the length direction of the connecting groove 3292; By making the side wall diameter of the pulling plate larger than the inner wall diameter of the third through hole, the rod body 3232 is restricted from entering the housing 3231 , which is convenient for practical use.

[0037] See also Fig.11 and Fig.12 , the counterweight assembly 315 includes: The plate body 3151 is fixed at the bottom of the clamping plate 316, and a mounting rod 3152 is fixed at the top of the plate body 3151.

After the clamping plate 316 is inserted into the connecting groove 3292, the bottom of the wheel body is level with the bottom of the connecting piece 322.

[0038] In a specific implementation, by setting a plate body 3151 and a mounting rod 3152 on the side of the clamping plate 316 away from the connecting piece 322, it is convenient to set a counterweight block and the like on the side wall of the mounting rod 3152 to adjust the force on both sides of the column 2, thereby ensuring the stability of the column 2 and improving the stability of the lifting. By setting a wheel body, the friction between the mounting plate and the ground is reduced, thereby reducing the power output of the rotating component 4 when the counterweight block and the like rotate with the connecting piece 322.

[0039] The pressure sensor 737 and other electronic devices of the present invention are connected to an external power source and a controller via wires for practical control and use. This is prior art and will not be elaborated on here.

[0040] The lifting assembly 6 usually includes a winch, etc., and the winch can move horizontally on the cross column 5 to meet actual lifting needs. The winch retracts and releases the rope to lift the hull structure. The rotating assembly 4 is usually achieved by installing a motor at the inner upper end of the column 2, and connecting the output shaft of the motor to the input shaft of the reducer, and the output shaft of the reducer is connected to the cross column 5 to drive the cross column 5 to rotate. These are all existing technologies and will not be elaborated here.

[0041] The embodiment of the present invention further provides a method for hoisting a hull structure hoisting device that is easy to install and use, using a hull structure hoisting device that is easy to install and use, the method comprising the following steps: S1: The column 2 is installed on the base 1 at the specified position through the disassembly and assembly mechanism 7, so as to hoist the hull structure. The column 2, the rotating assembly 4 and the cross column 5 can be easily disassembled and assembled through the disassembly and assembly mechanism 7, so as to facilitate the installation of the column 2 on the base 1 at the specified position. Since the base 1 is usually fixed on the specified ground by bolts, etc., it is inconvenient to disassemble and assemble. In order to meet the flexibility of hoisting, the column 2 and the base 1 are designed to be separated, and the disassembly and assembly are carried out through the disassembly and assembly mechanism 7, which is convenient for actual installation and use; S2: During the lifting process, the anti-dumping mechanism 3 rotates synchronously with the cross column 5 to limit the cross column 5 from tipping over. During the lifting process, after the hull structure is lifted by the lifting assembly 6, the cross column 5, the lifting assembly 6 and the hull structure are driven to rotate by the rotating assembly 4 to lift the hull structure to the specified position. During this process, the anti-dumping mechanism 3 rotates synchronously with the cross column 5, so that the anti-dumping mechanism 3 is always on the same horizontal line with the cross column 5 and is located on both sides of the column 2 to reduce the probability of the hull structure being too heavy and tipping over, such as the inverted cross column 5, so as to facilitate the lifting of heavier hull structures and improve the stability of the lifting.
