Description

Technical Field

[0001] The invention relates to the technical field of hoisting frames, and in particular to a hoisting frame of an equipment carrying platform and a reinforcement method thereof. Background Art

[0002] Small submersibles or submersible drones can be used as a platform to carry a variety of equipment, and can achieve the purpose of hydrological monitoring and geological measurement of the ocean by diving into the deep sea. When removing the equipment-carrying platform from the water, it is necessary to install a lifting frame on the platform, and then lift the frame and the platform at the same time through the lifting mechanism.

[0003] The difference from lifting on flat ground is that lifting the frame and platform from the water requires overcoming the water pressure and water resistance of the deep sea. Therefore, in order to weaken the influence of water resistance on lifting, the top of the frame is generally set in a hemispherical shape, so as to reduce the water resistance of the frame when it is lifted up. The top of the frame is generally welded with a lifting ring for the lifting equipment to hook the lifting ring for lifting. During the lifting process, the welding part will be damaged or even broken due to resisting water pressure and water resistance, causing the lifting ring to detach, and then causing the frame and the carrying platform on it to sink into the water again. Summary of the invention

[0016] Beneficial effects:

[0017] (1) The present invention fixes the reinforcement block to the suspension rod welded with the suspension ring by non-welding means. The welding end of the suspension ring first penetrates the reinforcement block and is then welded to the suspension rod. At the same time, the welding end is also welded to the reinforcement block. The difficulty of installing the reinforcement block on the frame is extremely low, and the welding area and welding position of the suspension ring and the entire frame are increased, which helps to disperse the tensile force on the various welding parts of the suspension ring during the lifting process, thereby effectively avoiding the problem of the suspension ring being detached due to the welding part of the suspension ring and the frame being pulled apart.

[0029] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1 As shown, combined Figure 2 , Figure 3 and Figure 4 A lifting frame of an equipment carrying platform of the present invention includes a first lifting rod 2, a second lifting rod 3, a lifting ring 4 and a reinforcement block 5.

[0031] The first and second suspenders 2 and 3 are both extended in semicircular shapes at both ends. The first and second suspenders 2 and 3 are cross-arranged in the middle of the rod body and connected to form an inverted hemispherical frame, which helps to reduce the influence of water resistance when the frame is lifted up. The two ends of the first and second suspenders 2 and 3 extending downward are used to fasten the equipment mounting platform 1 and can be fixed to the outer shell of the equipment mounting platform 1 by fastening bolts.

[0032] The lifting ring 4 and the reinforcing block 5 are both arranged on the first suspension rod 2; the lifting ring 4 is in an inverted U shape, and the lifting ring 4 is arranged across the intersection of the first suspension rod 2 and the second suspension rod 3. The lifting ring 4 is welded to the first suspension rod 2 and is provided with two welding ends 41, which are the two bottom ends of the inverted U shape. The reinforcing block 5 is fastened to the first suspension rod 2, and the two welding ends 41 penetrate the reinforcing block 5 and are connected to the first suspension rod 2, and the outer peripheral wall of the welding end 41 is welded to the reinforcing block 5. When the reinforcing block 5 is not provided, the welding part between the lifting ring 4 and the first suspension rod 2 has only two welding ends 41, so the lifting ring 4 resists water pressure and water resistance, and the force is mainly concentrated on the two welding ends 41, and the two welding ends 41 are directly subjected to the tensile force in the vertical direction along the welding surface, so the risk of being broken is very high; while in this embodiment, in addition to being welded to the first suspension rod 2, the outer peripheral wall of the welding end 41 is also welded to the inner wall of the part where the reinforcing block 5 penetrates, not only the welding area is larger and the welding parts are more, but also the welding part between the welding end 41 and the reinforcing block 5 is the outer peripheral wall of the welding end 41, and the tensile force direction there is parallel to the welding surface, so the welding surface is subjected to shear force, and it is more difficult for the welding surface to be detached. Through the above-mentioned reinforcement means, the welding strength between the lifting ring 4 and the overall frame is greatly improved, avoiding the problem of the lifting ring 4 being detached and causing the lifting frame to sink again before it is out of the water.

[0033] exist Figure 2 In a preferred embodiment shown, in order to improve the overall structural strength of the lifting frame, a connecting rod 6 is also included.

[0034] Among them, a plurality of 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 a plurality of connecting rods 6 are arranged around the intersection of the two suspension rods and are connected to form a circle around a circle; in addition, multiple circles of connecting rods 6 can be arranged up and down, and the radius of each circle of connecting rods 6 gradually increases 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.

[0035] exist Figure 8 In a preferred embodiment shown, for equipment mounting platforms 1 of different sizes and aspect ratios, the connection parts between the ends of the two suspension rods 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 suspension rod 2 and the second suspension rod 3 also needs to be adjusted, and therefore a rotating shaft 7 is also included.

[0036] The rotating shaft 7 is arranged at the intersection of the first suspension rod 2 and the second suspension rod 3 and passes through the first suspension rod 2, the second suspension rod 3 and the reinforcing block 5 at the same time; the ends of the first suspension rod 2 and the second suspension rod 3 rotate around the rotating shaft 7, and the distance between the adjacent ends of the first suspension rod 2 and the second suspension rod 3 is adjusted. For example, when the four connection parts of the two suspension rods and the equipment mounting platform 1 are arranged in a square, assuming that the first suspension rod 2 and the second suspension rod 3 are the same length, the intersection angle of the first suspension rod 2 and the second suspension rod 3 needs to be rotated to a right angle. Correspondingly, the length of the connecting rod 6 is telescopic and variable to adapt to the change of the relative position of the first suspension rod 2 and the second suspension rod 3.

[0037] exist Figure 8 In a preferred embodiment shown in the figure, in a specific embodiment, the first suspension rod 2 includes a first rod body 21 and a connecting plate 22 , and the second suspension rod 3 includes a second rod body 31 and a rotating block 32 .

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 rod bodies 21 form a window structure.

[0040] The two second rod bodies 31 are symmetrically arranged on both sides of the rotating shaft 7; the rotating block 32 is connected between the two second rod bodies 31 and connected with the two second rod bodies 31 to form the second suspension rod 3. The rotating block 32 is arranged between the two connecting plates 22, that is, arranged in the window structure.

[0041] 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.

[0042] The two ends of the reinforcing block 5 are respectively fastened to the two first rods 21. By fastening the two first rods 21, the reinforcing block 5 actually has a slight movable range between the reinforcing block 5 and the first rods 21, and the reinforcing block 5 is arranged across the two first rods 21 to play a bridging role. Moreover, the reinforcing block 5 in this structure will not hinder the rotatability of the rotating shaft 7 while playing a reinforcing role.

[0043] exist Figure 8 In a preferred embodiment shown, the rotating block 32 is a cylindrical block to avoid the problem that the rotating block 32 may be stuck when rotating in the window structure.

[0044] exist Figure 7 In a preferred embodiment shown, in order to realize the telescopic and variable length function of the connecting rod 6 , the connecting rod 6 includes a third rod body 61 and a fourth rod body 62 .

[0045] One end of the third rod body 61 is connected to the first suspension rod 2 , and the other end of the third rod body 61 extends toward the second suspension rod 3 along the extending direction of the connecting rod 6 .

[0046] One end of the fourth rod body 62 is connected to the second suspension rod 3, and the other end of the fourth rod body 62 is inserted into the third rod body 61 along the extension direction of the connecting rod 6. The part of the fourth rod body 62 inserted into the third rod body 61 is locked by a fastener, and a rotating handle locking mechanism similar to that of a lure fishing rod can be adopted; the second suspension rod 3 rotates relative to the first suspension rod 2 and adjusts the distance between the adjacent ends of the first suspension rod 2 and the second suspension rod 3, and adjusts the length of the part of the fourth rod body 62 inserted into the third rod body 61.

[0047] exist Figure 7 In a preferred embodiment shown, the rod diameter of the fourth rod 62 is smaller than the rod diameter of the third rod 61, so that the fourth rod 62 can be retracted 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 separate from the third rod 61 when extended.

[0048] exist Figure 5 In a preferred embodiment shown, in order to reduce the overall weight of the hanging frame, the reinforcing block 5 is a hollow shell, and the first hanging rod 2 and the second hanging rod 3 are also hollow rod bodies.

[0049] exist Figure 6 In a preferred embodiment shown, the first hanger 2 and the second hanger 3 have the same length, and the first hanger 2 and the second hanger 3 have the same rod diameter, so that the bottom ends of the two hangers can extend to the same height to be connected to the outer shell of the equipment mounting platform.

[0050] like Figure 1 As shown, combined Figure 2 , Figure 3 and Figure 4 A method for reinforcing a lifting frame of an equipment carrying platform of the present invention is used to reinforce the lifting frame of the equipment carrying platform 1 and obtain the lifting frame of the equipment carrying platform 1, comprising the following steps:

[0051] Step 1: a reinforcing block 5 is arranged at the intersection of the first suspension rod 2 and the second suspension rod 3 , and a through hole is opened on the reinforcing block 5 according to the outer diameter of the welding end 41 of the suspension ring 4 .
