Description

Technical Field

[0001] This invention relates to the field of hoisting frame technology, and more particularly to hoisting frames for equipment mounting platforms and their reinforcement methods. Background Technology

[0002] Small submersible vehicles or underwater drones can serve as platforms carrying various devices to conduct hydrological monitoring and geological surveys in the deep sea. When removing such a platform from the water, a lifting frame needs to be installed on the platform, and then a lifting mechanism is used to lift the frame and the platform simultaneously.

[0003] The difference between lifting on flat ground and lifting a frame and platform from water is that the pressure and resistance of the deep sea must be overcome. Therefore, to reduce the impact of water resistance on the lifting process, the top of the frame is generally designed as a hemispherical shape, thus reducing the water resistance encountered during lifting. The top of the frame is usually welded with lifting rings for the lifting equipment to hook onto. These welded parts can be damaged or even break during lifting due to the resistance to water pressure, causing the rings to detach and resulting in the frame and the platform re-sinking into the water. Summary of the Invention

[0004] In view of this, the present invention proposes a hoisting frame for the equipment mounting platform and a reinforcement method thereof, which is used to solve the problem that the welded parts of the lifting rings may be damaged or even broken during the hoisting process due to resistance to water pressure and water resistance.

[0005] The technical solution of this invention is implemented as follows: This invention provides a hoisting frame for an equipment mounting platform, including a first hoist and a second hoist, both ends of which extend into a semi-circle; a lifting ring and a reinforcing block are both disposed on the first hoist; wherein, the first hoist and the second hoist are intersected and connected in the middle of the rod body to form a hemispherical frame, and the two ends of the first hoist and the second hoist are used to fasten the equipment mounting platform; the lifting ring is straddling the intersection of the first hoist and the second hoist, and the lifting ring is welded to the first hoist and has two welded ends; the reinforcing block is fastened to the first hoist, and both welded ends penetrate the reinforcing block and are connected to the first hoist, and the outer peripheral wall of the welded end is welded to the reinforcing block.

[0006] Based on the above technical solution, preferably, it also includes several connecting rods, which are respectively connected between the adjacent ends of the first and second suspension rods; wherein, the connecting rods, the first suspension rod and the second suspension rod are connected to form a hemispherical frame, and the connecting rods limit the distance between the adjacent ends of the first and second suspension rods.

[0007] More preferably, it also includes a pivot shaft, which is located at the intersection of the first and second rods and passes through the first rod, the second rod, and the reinforcing block; wherein the ends of the first and second rods rotate around the pivot shaft and adjust the distance between adjacent ends of the first and second rods; the length of the connecting rod is variable.

[0008] More preferably, the first lifting rod includes two first rod bodies symmetrically arranged on both sides of the rotating shaft; two connecting plates connected between the two first rod bodies and forming a first lifting rod; the second lifting rod includes two second rod bodies symmetrically arranged on both sides of the rotating shaft; a rotating block connected between the two second rod bodies and forming a second lifting rod; wherein, the two connecting plates are spaced apart along the axial direction of the rotating shaft; the rotating block is arranged between the two connecting plates; one end of the rotating shaft passes through the connecting plate away from the reinforcing block, and the other end of the rotating shaft passes through the rotating block, another connecting plate, and the reinforcing block in sequence; both ends of the reinforcing block are respectively fastened to the two first rod bodies.

[0009] A further preferred option is to use cylindrical blocks.

[0010] More preferably, the connecting rod includes a third rod and a fourth rod; one end of the third rod is connected to the first lifting rod, and the other end of the third rod extends toward the second lifting rod along the extension direction of the connecting rod; one end of the fourth rod is connected to the second lifting rod, and the other end of the fourth rod is inserted into the third rod along the extension direction of the connecting rod, and the portion of the fourth rod inserted into the third rod is locked by fasteners; the second lifting rod rotates relative to the first lifting rod and adjusts the distance between adjacent ends of the first lifting rod and the second lifting rod, and adjusts the length of the portion of the fourth rod inserted into the third rod.

[0011] More preferably, the diameter of the fourth rod is smaller than the diameter of the third rod, and the length of the fourth rod is greater than the length of the third rod.

[0012] Based on the above technical solutions, the preferred option is a hollow shell for the reinforcing block.

[0013] Based on the above technical solutions, preferably, the first and second suspension rods have the same length and the same diameter.

[0014] On the other hand, the present invention also provides a method for reinforcing the hoisting frame of an equipment mounting platform, used to reinforce the hoisting frame of the equipment mounting platform and obtain the aforementioned hoisting frame of the equipment mounting platform, comprising the following steps: Step 1, setting a reinforcing block at the intersection of the first and second lifting rods, and opening a through hole in the reinforcing block according to the outer diameter of the welding end of the lifting ring; Step 2, passing the two welding ends of the lifting ring through the through hole of the reinforcing block and abutting against the first lifting rod, and welding the lifting ring to the first lifting rod through the two welding ends; Step 3, fastening both ends of the reinforcing block to the first lifting rod so that the reinforcing block is in close contact with the first lifting rod, and then welding the reinforcing block to the welding ends.

[0015] The hoisting frame and reinforcement method of the equipment mounting platform of the present invention have the following advantages over the prior art:

[0016] (1) In this invention, a reinforcing block is fixed to a lifting rod with a lifting ring by a non-welding means. The welding end of the lifting ring first passes through the reinforcing block and is then welded to the lifting rod. At the same time, the welding end is also welded to the reinforcing block. The difficulty of adding a reinforcing block to the frame is extremely low, and the welding area and welding position of the lifting ring and the entire frame are increased. This helps to disperse the tensile force on each welded part of the lifting ring during the lifting process, thereby effectively avoiding the problem of the lifting ring detaching due to the breakage of the welded part between the lifting ring and the frame.

[0017] (2) The frame of the present invention is composed of two lifting rods connected at the middle position with a cross axis. The two lifting rings can rotate around the cross part as the center axis, so that the connection position between the ends of the two lifting rods and the frame can be adjusted according to the size of the lifting frame. At the same time, the reinforcing block is straddling the cross part of the two lifting rods, which not only does not hinder the rotation of the lifting rods, but also makes the lifting rings bear force on the same vertical line as the center of gravity of the frame during lifting, thus preventing the frame from overturning during the lifting process.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, combined with Figure 2 , Figure 3 and Figure 4 The present invention provides a hoisting frame for a device mounting platform, comprising a first hoisting rod 2, a second hoisting rod 3, a hoisting ring 4, and a reinforcing block 5.

[0030] Both ends of the first boom 2 and the second boom 3 extend into a semi-circle. The first boom 2 and the second boom 3 are intersected and connected in the middle of the boom body to form an inverted hemispherical frame. The hemispherical frame helps to reduce the impact of water resistance when the frame is lifted. The two ends of the first boom 2 and the second boom 3 extending downward are used to fasten and connect to the equipment mounting platform 1, and can be fixed to the outer shell of the equipment mounting platform 1 by fastening bolts.

[0031] Both the lifting ring 4 and the reinforcing block 5 are mounted on the first lifting rod 2. The lifting ring 4 is inverted U-shaped and spans the intersection of the first lifting rod 2 and the second lifting rod 3. The lifting ring 4 is welded to the first lifting rod 2 and has two welded ends 41, which are the two bottom ends of the inverted U-shape. The reinforcing block 5 is fastened to the first lifting rod 2, and both welded ends 41 pass through the reinforcing block 5 and are connected to the first lifting rod 2. The outer peripheral wall of the welded ends 41 is welded to the reinforcing block 5. Without the reinforcing block 5, the welding point between the lifting ring 4 and the first lifting rod 2 has only two welding ends 41. Therefore, the lifting ring 4's resistance to water pressure and water resistance is mainly concentrated on these two welding ends 41, which are directly subjected to tensile force perpendicular to the welding surface, making them highly susceptible to breakage. In this embodiment, in addition to welding to the first lifting rod 2, the outer peripheral wall of the welding end 41 is also welded to the inner wall of the reinforcing block 5 through which it penetrates. This results in a larger welding area and more welding points. Furthermore, the welding point between the welding end 41 and the reinforcing block 5 is on the outer peripheral wall of the welding end 41, where the tensile force is parallel to the welding surface. Therefore, the welding surface is subjected to shear force, making it much less likely for the welding surface to detach. Through these reinforcement methods, the welding strength between the lifting ring 4 and the overall frame is significantly improved, preventing the lifting ring 4 from detaching and causing the lifting frame to re-sink before even leaving the water.

[0032] exist Figure 2 In a preferred embodiment shown, a connecting rod 6 is also included to improve the overall structural strength of the hoisting frame.

[0033] Several connecting rods 6 are respectively connected between the adjacent ends of the first suspension rod 2 and the second suspension rod 3; the connecting rods 6, the first suspension rod 2, and the second suspension rod 3 are connected to form a hemispherical frame, and the connecting rods 6 are arranged around the intersection of the two suspension rods and form a circle; in addition, multiple circles of connecting rods 6 can be arranged vertically, with the radius of each circle of connecting rods 6 gradually increasing from top to bottom. At the same time, the connecting rods 6 also have the function of limiting the distance between the adjacent ends of the first suspension rod 2 and the second suspension rod 3.

[0034] exist Figure 8 In a preferred embodiment shown, for equipment mounting platforms 1 of different sizes and aspect ratios, the connection points between the ends of the two booms and the equipment mounting platform 1 are different. For example, if the aspect ratio of the equipment mounting platform 1 is different, the distance between the adjacent ends of the first boom 2 and the second boom 3 also needs to be adjusted. Therefore, a rotating shaft 7 is also included.

[0035] The rotating shaft 7 is located at the intersection of the first lifting rod 2 and the second lifting rod 3, passing through both the first lifting rod 2, the second lifting rod 3, and the reinforcing block 5. The ends of the first lifting rod 2 and the second lifting rod 3 rotate around the rotating shaft 7, adjusting the distance between adjacent ends of the first lifting rod 2 and the second lifting rod 3. For example, when the two lifting rods and the four connecting parts of the equipment mounting platform 1 are arranged in a square, assuming that the first lifting rod 2 and the second lifting rod 3 are of the same length, the intersection angle between the first lifting rod 2 and the second lifting rod 3 needs to be rotated to a right angle. Correspondingly, the length of the connecting rod 6 is variable to accommodate changes in the relative positions of the first lifting rod 2 and the second lifting rod 3.

[0036] exist Figure 8 In a preferred embodiment shown, in a specific embodiment, the first lifting rod 2 includes a first rod body 21 and a connecting plate 22, and the second lifting rod 3 includes a second rod body 31 and a rotating block 32.

[0037] Among them, the two first rods 21 are symmetrically arranged on both sides of the rotating shaft 7.

[0038] Two connecting plates 22 are connected between two first rods 21 and form a first hanging rod 2. The two connecting plates 22 are spaced apart along the axial direction of the rotating shaft 7. The two connecting plates 22 and the adjacent ends of the two first rods 21 form a window structure.

[0039] Two second rods 31 are symmetrically arranged on both sides of the pivot 7; a rotating block 32 is connected between the two second rods 31 and forms a second hanging rod 3. The rotating block 32 is arranged between the two connecting plates 22, that is, within the window structure.

[0040] One end of the rotating shaft 7 passes through the connecting plate 22 away from the reinforcing block 5, and the other end of the rotating shaft 7 passes through the rotating block 32, another connecting plate 22 and the reinforcing block 5 in sequence.

[0041] The two ends of the reinforcing block 5 are respectively fastened to the two first rods 21. By fastening the reinforcing block 5 to the two first rods 21, there is actually a slight range of motion between the reinforcing block 5 and the first rods 21. At the same time, the reinforcing block 5, spanning between the two first rods 21, acts as a bridge. Moreover, in this structure, the reinforcing block 5, while providing reinforcement, does not hinder the rotational capability of the rotating shaft 7.

[0042] exist Figure 8 In a preferred embodiment shown, the rotating block 32 is a cylindrical block to avoid the problem of the rotating block 32 getting stuck when rotating within the window structure.

[0043] exist Figure 7 In a preferred embodiment shown, in order to realize the variable length extension function of the link 6, the link 6 includes a third link 61 and a fourth link 62.

[0044] One end of the third rod 61 is connected to the first lifting rod 2, and the other end of the third rod 61 extends toward the second lifting rod 3 along the extension direction of the connecting rod 6.

[0045] One end of the fourth rod 62 is connected to the second rod 3, and the other end of the fourth rod 62 is inserted into the third rod 61 along the extension direction of the connecting rod 6. The part of the fourth rod 62 inserted into the third rod 61 is locked by fasteners, which can be similar to the rotating grip locking mechanism of a lure fishing rod. The second rod 3 rotates relative to the first rod 2 and adjusts the distance between the adjacent ends of the first rod 2 and the second rod 3, and adjusts the length of the part of the fourth rod 62 inserted into the third rod 61.

[0046] exist Figure 7 In a preferred embodiment shown, the diameter of the fourth rod 62 is smaller than that of the third rod 61, so that the fourth rod 62 can retract into the third rod 61; and the length of the fourth rod 62 is greater than the length of the third rod 61, so that the fourth rod 62 will not detach from the third rod 61 when it extends.

[0047] exist Figure 5 In a preferred embodiment shown, in order to reduce the overall weight of the hoisting frame, the reinforcing block 5 is a hollow shell, and the first hoisting rod 2 and the second hoisting rod 3 are also hollow rods.

[0048] exist Figure 6 In a preferred embodiment shown, the first boom 2 and the second boom 3 are of the same length and have the same diameter, so that the bottom ends of the two booms can extend to the same height to connect with the housing of the equipment mounting platform.

[0049] like Figure 1 As shown, combined with Figure 2 , Figure 3 and Figure 4 The present invention discloses a method for reinforcing the hoisting frame of an equipment mounting platform, used to reinforce the hoisting frame of the equipment mounting platform 1 and obtain the aforementioned hoisting frame of the equipment mounting platform 1, comprising the following steps:

[0050] Step 1: Install a reinforcing block 5 at the intersection of the first lifting rod 2 and the second lifting rod 3, and make a through hole in the reinforcing block 5 according to the outer diameter of the welding end 41 of the lifting ring 4.

[0051] Step 2: Pass the two welding ends 41 of the lifting ring 4 through the through hole of the reinforcing block 5 and abut against the first lifting rod 2, and weld the lifting ring 4 to the first lifting rod 2 through the two welding ends 41.

[0052] Step 3: Securely connect both ends of the reinforcing block 5 to the first hanger rod 2, so that the reinforcing block 5 is in close contact with the first hanger rod 2, and then weld the reinforcing block 5 to the welding end 41.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
