Description

Technical Field

[0001] The present invention relates to the technical field of cage diving hoisting, and particularly relates to a double-cage diving hoisting system. Background Art

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

[0003] In the ocean or on the sea surface, it mostly shows salt spray corrosion. The corrosion rate varies with the changes in relative humidity, temperature, and wind direction. In this environment, waves, tides, and currents also generate low-frequency reciprocating stresses and impacts on metal components. In addition, marine microorganisms, attached organisms, and their metabolites all have direct or indirect accelerating effects on 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 internationally. Normally, divers need to swim from the water surface to underwater by themselves, which is time-consuming and laborious. Now, generally, divers are directly hoisted to the predetermined water area through a diving hoisting device, which is time-saving and labor-saving. However, since the hoisting device needs to be used in conjunction with a ship and is in the marine environment for a long time, the wire arranging device used in the winch of the hoisting device is synchronously connected to the drum, and the steel wire on the swing frame is neatly arranged on the drum through the wire arranging device. The wire arranging device needs to drive the swing frame to reciprocate. Due to the spiral groove structure of the wire arranging groove, it is easy to rust in the marine environment, resulting in an increase in the friction force between the slot block and the wire arranging groove during sliding. Moreover, the slot block continuously scrapes off the rust blocks on the surface of the wire arranging groove. After long-term use, the groove width of the wire arranging groove will increase, and the slot block is likely to run out of the groove when passing through the intersection of the spiral grooves, resulting in non-uniform wire arrangement. Summary of the Invention

[0005] The purpose of the present invention is to provide a double-cage diving hoisting system to solve the above problems.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A double-cage diving hoisting system includes a bottom frame, a support platform, and a hoisting frame. The support platform is fixed on the support frame on one side of the bottom frame, and the hoisting frame rotates around the other side of the bottom frame. The bottom frame is also connected to the hoisting frame through a hydraulic cylinder. Two sets of hoisting assemblies are arranged on the support platform and the hoisting frame.

Among them, the intermittent wire arranging swing member swings around the covering member under the drive of the wire arranging groove, and the storage channel is communicated with the liquid inlet channel or the liquid outlet channel.

[0009] The lubricating oil storage tank and the pump body are installed on the bottom frame. The inlet of the pump body is connected to the lubricating oil storage tank through a pipeline, and the outlet of the pump body is connected to the liquid inlet channel of the covering member through a pipeline. The lubricating liquid in the lubricating oil storage tank lubricates the intermittent wire arranging swing member and the wire arranging groove through the storage channel.

[0010] Further, there are two support platforms arranged in a stepped manner. A total of four winches are provided and evenly distributed on the two support platforms. The winches in the upper and lower positions form a cage driving part. Each winch includes a drum, a frame, and a hydraulic motor. Both ends of the shaft of the drum are installed on both sides of the frame. A steel rope is wound on the drum. The hydraulic motor is arranged on the bottom frame and connected to one end of the shaft of the drum.

[0011] Further, the double-cage is composed of two cages. A buckle is provided on the top of each cage, and positioning sleeves are provided on both sides and the bottom end of the cage.

[0012] The steel rope on one drum of each cage driving part is connected to the buckle through a pulley, and the steel rope on the other drum passes through the positioning sleeve on one side of the cage, then passes through the bottom and the positioning sleeves on the side in sequence, and is connected to the locking hook on the suspension rack.

[0013] Further, a guide receiving groove is provided on the cycloidal frame. The guide component includes a first guide roller and a second guide roller. The first guide roller and the second guide roller are arranged side by side in the guide receiving groove and rotate around the cycloidal frame. The steel rope passes through the gap between the first guide roller and the second guide roller.

[0014] Further, the intermittent wire arranging swing member includes a slot block, an insertion shaft, and a turntable. The center of one side surface of the turntable is fixed to the insertion shaft, and the other end of the insertion shaft is connected to the slot block. The slot block is inserted into the wire arranging groove. The storage channel is arranged along the radial direction of the turntable. Among them, one end of the storage channel is open and the other end is closed.

[0015] Further, the elastic member includes a sleeve, an inner sealing plate, an outer sealing plate, a push rod and a spring. The sleeve is fixed at the closed end of the storage channel. The inner sealing plate is located inside the sleeve and divides the inner cavity into a left cavity and a right cavity. The push rod connected to the inner sealing plate passes through the left cavity and the sleeve and is fixed to the outer sealing plate. The spring is placed in the right cavity, and both ends of the spring are fixed to the sleeve and the inner sealing plate respectively.

[0016] Further, the outer sealing plate is sealingly connected to the storage channel. The sleeve stores damping fluid, and the inner sealing plate is also provided with a slow-flow hole communicating the left cavity and the right cavity.

[0017] Further, the covering member is welded to the cycloid frame, the turntable is inserted into the covering member and sealingly connected, and the lubricating fluid flowing into the liquid inlet channel flows out from the liquid outlet channel under the thrust of the spring.

[0018] Further, a collecting tank is placed on the support platform below the wire discharge groove, and the collecting tank is connected back to the lubricating oil storage tank through a processing device.

[0019] Further, a detachable collar is sleeved on the insertion shaft. Among them, a ring groove is opened at the top of the collar, and the opening of the pipe connected to the liquid outlet channel faces the ring groove.

[0020] Technical effects and advantages of the present invention:

[0021] During the liquid injection process of the slot block, the storage channel is communicated with the liquid inlet channel. At this time, the pump body extracts the lubricating fluid in the lubricating oil storage tank and sends it into the storage channel through the liquid inlet channel. During the liquid discharge process, the lubricating fluid in the liquid outlet channel falls on the slot block, and the power during the switching of the liquid injection process and the liquid discharge process is the reel. As long as the reel rotates, the liquid discharge process and the continuous switching of the liquid injection process can be realized. The elastic member ensures that the lubricating oil in the storage channel door is pushed into the liquid outlet channel in a uniform manner, thereby avoiding the problem that the lubricating fluid flows too fast, resulting in too much local lubricating fluid and too little local lubricating fluid. And when the slot block is in the liquid discharge process, the pipe opening connected to the liquid outlet channel is aligned with the main channel, and the lubricating fluid flowing out from the liquid outlet channel passes through the main channel and flows out towards the sub-channels on both sides, which can lubricate both sides of the slot block and the wire discharge groove. During the sliding process of the slot block, the lubricating oil is applied to both sides of the wire discharge groove to achieve the purpose of lubrication, avoid wear and also play a role in rust prevention, avoid knocking off rust blocks, and make the slot block slide in the established groove, always achieving the purpose of neatly arranging wires.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1: Refer to Figures 1 - 6, which is the first embodiment of the present invention, provides a double-cage diving hoisting system, including a bottom frame 1, a support platform 2, and a hoisting frame 3. The support platform 2 is fixed on the support frame on one side of the bottom frame 1, and the hoisting frame 3 rotates around the other side of the bottom frame 1. The bottom frame 1 is also connected to the hoisting frame 3 through a hydraulic cylinder. Two groups of hoisting assemblies are provided on the support platform 2 and the hoisting frame 3. Each hoisting assembly includes a winch 4 and a pulley. The winch 4 is installed on the support platform 2, and the pulley is arranged on the hoisting frame 3;

[0037] The hoisting frame 3 rotates around the bottom frame 1. When the equipment is not in use, the rotation of the hoisting frame 3 is supported by the bearing brackets on both sides of the bottom frame 1. The double cage 11 is located on the grille of the bottom frame 1. When it is necessary to hoist and lower the double cage 11, the cylinder rod of the hydraulic cylinder extends, allowing the hoisting frame 3 to rotate around the bottom frame 1. Then the top of the hoisting frame 3 can rotate to the outside of the bottom frame 1. At this time, the double cage 11 is located outside the bottom frame 1. Driven by the winch 4, the double cage 11 can be lowered or raised.

[0038] A double cage 11 is also placed on the grille of the bottom frame 1 below the hoisting frame 3. A sliding cycloidal frame 41 is installed on the guide rod of the winch 4. Guide assemblies 5 and lubricating assemblies 6 are installed on the cycloidal frame 41. The steel wire 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. A buckle is provided at the top of each cage, and positioning sleeves are provided on both sides and at the bottom of the cage;

[0040] The steel wire rope on one drum 42 of each cage driving part is connected to the buckle through a pulley, and the steel wire rope on the other drum 42 passes through the positioning sleeve on one side of the cage and is sequentially connected to the locking hook on the hoisting frame 3 after passing through the positioning sleeves at the bottom and on the side.

[0041] Among them, the steel wire rope through one drum 42 is used for lifting and lowering the cage. The steel wire rope on the other drum 42 can play an auxiliary support role and also avoid the shaking of the cage, which can play a better protective role.

[0042] A guide receiving groove is formed on the cycloidal frame 41. 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 cycloidal frame 41. The steel wire rope passes through the gap between the first guide roller 51 and the second guide roller 52, which is used to pull the steel wire rope to arrange the line to the left or right and reduce the friction force on the steel wire rope when the steel wire rope is wound and unwound.

[0043] There are two support platforms 2 which are arranged in a stepped manner. A total of four winches 4 are provided and evenly distributed on the two support platforms 2. The winches 4 in the upper and lower positions form a cage driving part, and the two cage driving parts are used to drive the double cage 11 to lift and lower.

[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 mounted on both sides of the frame 43. A steel wire rope is wound around 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 arranging shaft 61 through a belt for the wire arranging shaft 61 and the drum 42 to rotate synchronously. The hydraulic motor 44 is used to drive the drum 42 to rotate, so as to realize the winding and unwinding of the steel wire rope.

[0045] The lubrication assembly 6 includes a wire arranging shaft 61, a lubricating oil storage tank 62, a pump body 63 and an intermittent wire arranging swing member 64. Both ends of the wire arranging shaft 61 are mounted on the bearings of the winch 4. A wire arranging groove 611 is arranged on the wire arranging shaft 61. One end of the intermittent wire arranging swing member 64 is inserted into the wire arranging groove 611, and the other end of the intermittent wire arranging swing member 64 is inserted into the covering member 8 on the cycloidal frame 41.

[0046] A storage channel is arranged on the intermittent wire arranging swing member 64. One end of the storage channel is open and the other end is closed. The lubricating oil storage tank 62 and the pump body 63 are mounted on the bottom frame 1. The inlet of the pump body 63 is connected to the lubricating oil storage tank 62 through a pipeline, and the outlet of the pump body 63 is connected to the liquid inlet channel 81 of the covering member 8 through a pipeline. An outlet channel 82 is also arranged on the covering member 8. The lubricating liquid in the lubricating oil storage tank 62 lubricates the intermittent wire arranging swing member 64 and the wire arranging groove 611 through the storage channel.

[0047] The intermittent wire arranging swing member 64 includes a slot block 641, a plug shaft 642 and a turntable 643. The center of one side surface of the turntable 643 is fixed to the plug shaft 642, and the other end of the plug shaft 642 is connected to the slot block 641. The slot block 641 is inserted into the wire arranging groove 611, and the storage channel is arranged along the radial direction of the turntable 643.

[0048] The guiding assembly 5 plays a role in supporting the steel wire rope, while the lubrication assembly 6 is used to lubricate the slot block 641 and the wire arranging groove 611. The cycloidal frame 41 drives the guiding assembly 5 and the lubrication assembly 6 to slide along the guiding rod. The power for the cycloidal frame 41 to slide is provided by the intermittent wire arranging swing member 64. The wire arranging groove 611 is a prior art. The slot block 641 of the intermittent wire arranging swing member 64 can be inserted into the wire arranging groove 611. When the drum 42 rotates to wind or unwind the steel wire rope, the wire arranging shaft 61 rotates synchronously. If the drum 42 rotates forward all the time, the slot block 641 slides in one direction along the wire arranging groove 611. When it slides to the outermost side at one end of the wire arranging shaft 61, the slot block 641 swings. When the slot block 641 slides to the other end of the wire arranging 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 reciprocally continuously to achieve the purpose of wire arranging of the steel wire rope.

[0049] Among them, the intermittent wire arranging swing member 64 swings around the covering member 8 under the drive of the wire arranging groove 611, and the storage channel communicates with the liquid inlet channel 81 or the liquid outlet channel 82;

[0050] A plate connected to a spring is further arranged in the storage channel, wherein the plate is sealed with the storage channel

[0051] During use, the outermost sides of both ends of the wire arranging groove 611 are respectively set as point "A" and point "B". When the winding drum 42 rotates, it drives the slot block 641 to slide along the wire arranging groove 611. During the period when the slot block 641 moves from "A" to "B", the slot block 641 always maintains an inclined angle, and the storage channel communicates with the liquid inlet channel 81. At this time, the pump body 63 pumps the lubricating liquid in the lubricating oil storage tank 62 through the liquid inlet channel 81 and sends it into the storage channel. 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 plate is pushed to move and the spring is compressed, 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 reverse direction once, and the storage channel communicates with the liquid outlet channel 82. The lubricating oil in the storage channel pushes the plate to move during the reset process of the spring, and the lubricating oil is pushed 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 insertion shaft 642. Therefore, during the sliding process of the slot block 641, the lubricating oil is applied to the wire arranging groove 611 under the influence of gravity, achieving the purpose of lubrication, avoiding wear and also being able to achieve the purpose of rust prevention, reducing the friction between the slot block 641 and the wire arranging groove 611. The purpose of rust prevention is to avoid knocking off the rust blocks, enabling the slot block 641 to always slide in the established groove, always achieving the purpose of neat wire arrangement. At this time, the liquid inlet channel 81 is sealed by the turntable 643, and the pump body 63 cannot pump the lubricating oil in the lubricating oil storage tank 62 into the storage channel.

[0053] As the slot block 641 passes through point "A" and then moves to point "B", the slot block 641 and the turntable 643 rotate in the reverse direction once again, and the storage channel communicates with the liquid inlet channel 81, and the lubricating oil is injected into the storage channel. The liquid outlet channel 82 is sealed by the turntable 643, and the lubricating oil cannot flow down.

[0054] This device adopts the wire arranging shaft 61 to drive the slot block 641 to continuously swing back and forth during rotation, achieving the purpose of switching back and forth between the two channels. The two actions of liquid injection and liquid discharge are continuously changed, so that during the use of the device, the lubricating oil can be continuously coated on the slot block 641 and the wire arranging groove 611.

[0055] Embodiment 2: Refer to Figures 7 - 8, this embodiment is different from the first embodiment. A detachable collar 9 is sleeved on the insertion shaft 642. The top of the collar 9 is provided with an annular groove. The pipe opening connected to the liquid outlet channel 82 faces the annular groove. The lubricating oil flowing into the liquid outlet channel 82 flows into the annular groove. A through hole is provided on the annular groove, and the lubricating oil flowing down through 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 lubricating effect is better.

[0056] After lubricating liquid is coated on the wire discharge groove 611, the pump body 63 stops pumping the lubricating liquid in the lubricating oil storage tank 62 until the lubricating oil on the wire discharge groove 611 and the slot block 641 is almost consumed, and then the pump body 63 is started to continue coating the lubricating liquid for lubrication.

[0057] Embodiment Three: Refer to Figures 9 - 10 , this embodiment is different from the second embodiment. An elastic member 7 is assembled in the storage channel. The elastic member 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 sealingly connected to the storage channel. The damping liquid is stored in the sleeve 71, and a slow flow hole communicating the left cavity and the right cavity is also provided on the inner sealing plate 72.

[0059] The covering member 8 is welded to the cycloid frame 41. The turntable 643 is inserted into the covering member 8 and is sealingly connected. 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 ensure that all the lubricating oil in the storage channel can flow out, the elastic member 7 is provided. During the liquid injection process, the pump body 63 pumps the lubricating liquid in the lubricating oil storage tank 62 through the liquid inlet channel 81 and sends it into the storage channel. As the lubricating oil in the storage channel increases, the outer sealing plate 73 is pushed to move towards the sleeve 71, and the inner sealing plate 72 moves synchronously and the spring is compressed. The damping liquid flows through the slow flow hole, allowing the inner sealing plate 72 to move at a uniform speed. During the liquid discharge process, under the elastic force of the spring, the inner sealing plate 72 moves in the reverse direction and pushes the outer sealing plate 73 to move towards 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, thus avoiding the problem that the lubricating oil flows too fast, resulting in too much lubricating liquid in some parts and too little lubricating liquid in other parts.

[0061] Embodiment Four: Refer to Figure 11, this embodiment is different from the third embodiment, and a collection tank is placed on the support platform 2 below the wire slot 611, which can collect the lubricating oil dripping from the wire slot 611. The collection tank is connected back to the lubricating oil storage tank 62 through an oil filter. The lubricating oil on the collection tank is processed by the oil filter and continues to be used for lubrication. The special oil filter for lubricating oil is mainly applicable to lubricating oil with high water content and many impurities, and can quickly remove impurities, moisture, gas in the oil and reduce the acid value, restoring the specific performance of the lubricating oil. After the lubricating oil is filtered by a coarse filter to remove large particle impurities, capillary condensation is generated by the demulsification filter element in the demulsifier, and small droplets will become large water droplets and separate from the oil. Dissolved water is continuously evaporated through heating under a vacuum state and discharged by a vacuum pump. After removing the moisture, the oil liquid passes through a fine filter to remove mechanical impurities, achieving the purpose of comprehensively purifying the oil quality.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
