Description

Technical Field

[0001] The invention relates to the technical field of cage diving and placing, in particular to a double-cage diving and placing system. Background Art

[0002] The corrosion of metals caused by the influence of the marine environment (seawater, marine atmosphere, marine organisms, etc.). It has electrochemical characteristics, so it is very easy to cause contact corrosion, oxygen concentration corrosion, crevice corrosion, and the corrosion rate and degree are also different. It can usually be divided into marine atmospheric corrosion, corrosion of the part intermittently wetted by seawater, corrosion of the part completely immersed in seawater, and corrosion in the seabed soil. The characteristics of marine corrosion are:

[0003] In the ocean or on the sea surface, it is mostly manifested as salt spray corrosion. The corrosion rate is related to the changes in relative humidity, temperature and wind direction. In this environment, waves, tides and currents also produce low-frequency reciprocating stress and impact on metal components. In addition, marine microorganisms, attached organisms and their metabolites directly or indirectly accelerate the corrosion process. Marine corrosion is mainly local corrosion, that is, corrosion that starts from the surface of the component and occurs in a very small area, such as galvanic corrosion, pitting corrosion, crevice corrosion, etc.

[0004] Diving has always been generally regarded as one of the high-risk and special industries in the world. Under normal circumstances, divers need to paddle from the water surface to underwater by themselves, which is time-consuming and laborious. Now, divers are generally lowered directly to the predetermined waters through diving lifting devices, which saves time and effort. However, since the lifting equipment needs to be used in conjunction with the ship, the lifting equipment is in the marine environment for a long time. The wire arranging device and the drum used in the winch of the lifting equipment are synchronously connected, and the wire arranging device is used to achieve the neat arrangement of the steel rope on the cycloidal frame on the drum. The wire arranging device needs to drive the cycloidal frame to move back and forth. Due to the spiral groove structure of the wire arranging trough, it is easy to rust in the marine environment, resulting in an increase in the friction between the slot block and the wire arranging trough, and the slot block constantly scrapes off the rust on the surface of the wire arranging trough. Long-term use will cause the width of the wire arranging trough to increase, and the slot block is easy to run into the wrong groove at the intersection of the spiral groove, resulting in the inability to arrange the wire neatly.

[0035] The following will be combined with the drawings in 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.

[0036] Example 1: Reference Figure 1-Figure 6, which is the first embodiment of the present invention, provides a double-cage diving hanging system, including a bottom frame 1, a support platform 2 and a hanging frame 3, wherein the support platform 2 is fixed on the support frame on one side of the bottom frame 1, and the hanging frame 3 rotates around the other side of the bottom frame 1, and the bottom frame 1 is also connected to the hanging frame 3 through a hydraulic cylinder, and two sets of hanging assemblies are arranged on the support platform 2 and the hanging frame 3, and each set of hanging assemblies includes a winch 4 and a pulley, the winch 4 is installed on the support platform 2, and the pulley is arranged on the hanging frame 3;

[0037] The hanging frame 3 rotates around the bottom frame 1. When the equipment is not in use, the hanging frame 3 rotates and is supported by the supporting frames on both sides of the bottom frame 1. The double cage 11 is located on the grille of the bottom frame 1. When the double cage 11 needs to be lifted and dived, the cylinder rod of the hydraulic cylinder is extended to allow the hanging frame 3 to rotate around the bottom frame 1. Then the top of the hanging frame 3 can be rotated to the outside of the bottom frame 1. At this time, the double cage 11 is located outside the bottom frame 1. The double cage 11 can be lowered or raised under the drive of the winch 4.

[0038] A double cage 11 is also placed on the grid of the bottom frame 1 below the hanging frame 3, a sliding cycloid frame 41 is installed on the guide rod on the winch 4, and a guide assembly 5 and a lubrication assembly 6 are installed on the cycloid frame 41. The steel rope wound on the winch 4 passes through the guide assembly 5 and the pulley and is connected to the double cage 11;

[0039] The double cage 11 is composed of two cages, each of which is provided with a buckle at the top, and positioning sleeves are provided on both sides and the bottom of the cage;

[0040] The steel rope on one drum 42 of each cage driving part is connected to the buckle through a pulley, and the steel rope on the other drum 42 passes through the positioning sleeve on one side of the cage and passes through the bottom and side positioning sleeves in turn to be connected to the locking hook on the hanging frame 3.

[0041] Among them, the steel rope passing through one drum 42 is used for lifting the cage, and the steel rope on the other drum 42 can not only provide auxiliary support but also prevent the cage from shaking, thereby playing a better protective role.

[0042] A guide receiving groove is provided on the cycloid frame 41, and the guide assembly 5 includes a first guide roller 51 and a second guide roller 52. The first guide roller 51 and the second guide roller 52 are arranged side by side in the guide receiving groove and rotate around the cycloid frame 41. The steel rope passes through the gap between the first guide roller 51 and the second guide roller 52, which is used to pull the steel rope to the left or right for wiring and to reduce the friction on the steel rope when the steel rope is reeled in and out.

[0043] There are two supporting platforms 2 arranged in a stepped manner, and there are four winches 4 evenly distributed on the two supporting platforms 2. The winches 4 at the upper and lower positions constitute a cage driving unit, and the two cage driving units are used to drive the double cage 11 to rise and fall.

[0044] Each winch 4 includes a drum 42, a frame 43 and a hydraulic motor 44. Both ends of the shaft of the drum 42 are installed on both sides of the frame 43. A steel rope is wound on the drum 42. The hydraulic motor 44 is arranged on the bottom frame 1 and connected to one end of the shaft of the drum 42. The other end of the shaft of the drum 42 is connected to the shaft of the wire arrangement shaft 61 through a belt, which is used for synchronous rotation of the wire arrangement shaft 61 and the drum 42. The hydraulic motor 44 is used to drive the drum 42 to rotate, thereby realizing the reeling and releasing of the steel rope.

[0045] The lubrication assembly 6 includes a wire arrangement shaft 61, a lubricating oil storage box 62, a pump body 63, and an intermittent wire arrangement swinging member 64. Both ends of the wire arrangement shaft 61 are mounted on the bearings of the winch 4. The wire arrangement shaft 61 is provided with a wire arrangement groove 611. One end of the intermittent wire arrangement swinging member 64 is inserted into the wire arrangement groove 611, and the other end of the intermittent wire arrangement swinging member 64 is inserted into the cover 8 on the oscillating frame 41.

[0046] A storage channel is provided on the intermittent wiring swing member 64, wherein one end of the storage channel is open and the other end is closed, the lubricating oil storage box 62 and the pump body 63 are installed on the bottom frame 1, the inlet of the pump body 63 is connected to the lubricating oil storage box 62 through a pipeline, and the outlet of the pump body 63 is connected to the liquid inlet channel 81 of the cover 8 through a pipeline, and the cover 8 is also provided with a liquid outlet channel 82, and the lubricating fluid in the lubricating oil storage box 62 lubricates the intermittent wiring swing member 64 and the wiring groove 611 through the storage channel.

[0047] The intermittent cable arrangement swinging member 64 includes a slot block 641, an insertion shaft 642 and a rotating disk 643. The center of one side of the rotating disk 643 is fixed to the insertion shaft 642. The other end of the insertion shaft 642 is connected to the slot block 641. The slot block 641 is inserted into the cable arrangement groove 611. The storage channel is arranged along the radial direction of the rotating disk 643.

[0048] The guide assembly 5 supports the steel rope, and the lubricating assembly 6 is used to lubricate the slot block 641 and the wire arrangement groove 611. The cycloidal frame 41 drives the guide assembly 5 and the lubricating assembly 6 to slide along the guide rod. The power for the sliding of the cycloidal frame 41 is provided by the intermittent wire arrangement swinging member 64. The wire arrangement groove 611 is a prior art. The slot block 641 of the intermittent wire arrangement swinging member 64 can be inserted into the wire arrangement groove 611. When the reel 42 rotates to wind up the steel rope or lengthen the steel rope, the wire arrangement shaft 61 rotates synchronously. If the reel 42 rotates forward all the time, the slot block 641 slides in one direction along the wire arrangement groove 611. When it slides to the outermost end of one end of the wire arrangement shaft 61, the slot block 641 swings. When the slot block 641 continues to slide the other end of the wire arrangement shaft 61 in the reverse direction, the slot block 641 continues to swing in the reverse direction, thereby driving the cycloidal frame 41 to move back and forth continuously to achieve the purpose of wire arrangement of the steel rope.

[0049] The intermittent wire arrangement swinging member 64 swings around the cover member 8 under the drive of the wire arrangement slot 611 and the storage channel is connected with the liquid inlet channel 81 or the liquid outlet channel 82;

[0050] A plate connected to the spring is also provided in the storage channel, wherein the plate is sealed with the storage channel.

[0051] When in use, the outermost ends of the cable groove 611 are respectively set as point "A" and point "B". When the reel 42 rotates, it drives the slot block 641 to slide along the cable groove 611. During the period when the slot block 641 moves from point "A" to point "B", the slot block 641 always maintains an angle of inclination, and the storage channel is connected with the liquid inlet channel 81. At this time, the pump body 63 extracts the lubricating liquid in the lubricating oil storage box 62 and sends it into the storage channel through the liquid inlet channel 81. Since the space of the storage channel is a fixed value, after the injected lubricating liquid reaches the upper limit, the pump body 63 cannot continue to send the lubricating liquid into the storage channel. For the purpose of quantitative lubrication, the push plate moves and squeezes the spring, which is set as the liquid injection process;

[0052] Then, during the period when the slot block 641 passes through point "B" and moves from point "B" to point "A", the slot block 641 and the turntable 643 rotate in the opposite direction once, and the storage channel is connected to the liquid outlet channel 82. During the process of spring reset, the lubricating oil in the storage channel pushes the plate to move and pushes the lubricating oil into the liquid outlet channel 82 and flows down, which is set as the liquid discharge process. The lubricating liquid in the liquid outlet channel 82 falls on the slot block 641 and the plug shaft 642, so that the slot block 641 is affected by gravity during the sliding process and the lubricating oil is coated on the cable groove 611, thereby achieving the purpose of lubrication, avoiding wear and tear, and also achieving the purpose of rust prevention, reducing the friction between the slot block 641 and the cable groove 611, and the purpose of rust prevention is to avoid knocking down the rust block, so that the slot block 641 always slides in the predetermined groove, and always achieves the purpose of neat cable arrangement, and the liquid inlet channel 81 is blocked by the turntable 643. At this time, the pump body 63 cannot extract the lubricating oil in the lubricating oil storage box 62 and send it to the storage channel.

[0053] As the slot block 641 passes through point "A" and moves to point "B", the slot block 641 and the turntable 643 continue to rotate in the opposite direction once, the storage channel is connected to the liquid inlet channel 81, the lubricating oil is injected into the storage channel, and the liquid outlet channel 82 is blocked by the turntable 643, and the lubricating oil cannot flow down.

[0054] The device uses a cable shaft 61 which drives the slot block 641 to swing back and forth continuously during rotation, thereby switching back and forth between the two channels. The two actions of injecting and discharging liquid are constantly changed, so that during the use of the device, the lubricating oil can be continuously applied to the slot block 641 and the cable slot 611.

[0055] Example 2: Reference Figure 7-Figure 8This embodiment is different from the first embodiment. A detachable sleeve ring 9 is sleeved on the plug shaft 642, wherein a ring groove is provided on the top of the sleeve ring 9, wherein the pipe opening connected to the liquid outlet channel 82 faces the ring groove, and the lubricating oil flowing into the liquid outlet channel 82 flows into the ring groove. A through hole is provided on the ring groove, and the lubricating oil flowing down from the through hole flows on the slot block 641, so that both sides of the slot block 641 are coated with lubricating liquid, and the lubrication effect is better.

[0056] After the lubricating liquid is applied to the cable groove 611, the pump body 63 is stopped to extract the lubricating liquid in the lubricating oil storage box 62 until the lubricating oil on the cable groove 611 and the slot block 641 is almost consumed, and then the pump body 63 is started to continue applying the lubricating liquid for lubrication.

[0057] Example 3: Reference Figure 9-10 This embodiment is different from the second embodiment. An elastic component 7 is installed in the storage channel. The elastic component 7 includes a sleeve 71, an inner sealing plate 72, an outer sealing plate 73, a push rod 74 and a spring. The sleeve 71 is fixed at the closed part of the storage channel. The inner sealing plate 72 is located in the sleeve 71 and divides the inner cavity into a left cavity and a right cavity. The push rod 74 connected to the inner sealing plate 72 passes through the left cavity and the sleeve 71 and is fixed to the outer sealing plate 73. The spring is placed in the right cavity, and both ends of the spring are fixed to the sleeve 71 and the inner sealing plate 72 respectively.

[0058] The outer sealing plate 73 is sealed and connected to the storage channel. The damping fluid is stored in the sleeve 71. The inner sealing plate 72 is also provided with a slow flow hole connecting the left cavity and the right cavity.

[0059] The cover 8 is welded to the cycloid frame 41 , the turntable 643 is inserted into the cover 8 and sealed, and the lubricating liquid flowing into the liquid inlet channel 81 flows out from the liquid outlet channel 82 under the thrust of the spring.

[0060] In order to control the flow rate of the lubricating oil in the storage channel and allow the lubricating oil in the storage channel to flow out, an elastic component 7 is provided. During the injection process, the pump body 63 draws the lubricating liquid in the lubricating oil storage box 62 and sends it into the storage channel through the liquid inlet channel 81. As the lubricating oil in the storage channel increases, the outer sealing plate 73 is pushed to move toward the sleeve 71, and the inner sealing plate 72 moves synchronously. The spring is compressed, and the damping liquid flows through the slow flow hole, allowing the inner sealing plate 72 to move at a uniform speed. During the discharge process, under the elastic force of the spring, the inner sealing plate 72 moves in the opposite direction to push the outer sealing plate 73 toward the liquid outlet channel 82. Similarly, the lubricating oil in the storage channel can be pushed into the liquid outlet channel 82 in a uniform manner, thereby avoiding the problem of too fast flow of the lubricating oil, resulting in too much local lubricating liquid and too little local lubricating liquid.

[0061] Example 4: Reference Fig.11This embodiment is different from the third embodiment, and a collecting tank is placed on the supporting platform 2 below the cable trough 611, which can collect the lubricating oil dripping from the cable trough 611. The collecting tank is connected to the lubricating oil storage box 62 through the oil filter. The lubricating oil on the collecting tank is processed by the oil filter and continues to be used for lubrication. The special oil filter for lubricating oil is mainly suitable for lubricating oil with high water content and many impurities. It can quickly remove impurities, moisture, gas in the oil and reduce the acid value, and restore the unique properties of the lubricating oil. After the lubricating oil is filtered to remove large particles of impurities, it will produce capillary condensation through the demulsification filter element in the demulsifier, and small droplets will become large water droplets and separate from the oil. The dissolved water is continuously evaporated by heating under vacuum and discharged by the vacuum pump. After removing the water, the oil passes through the fine filter to remove mechanical impurities, so as to achieve the purpose of comprehensive purification of the oil quality.

[0062] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
