[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The present application drives all rollers to move through a driving mechanism, so that the rollers move in the direction of the slide groove, so that all rollers move along the edge of the first fixed plate toward the axis of the through hole, until all rollers fit the outer wall of the protected tank body, so that the protected tank body is clamped on all rollers, and the protected tank body is clamped on the axis of the through hole by multiple rollers. The protected tank body can be driven to rotate within the multiple rollers through the setting of multiple rollers. Since liquefied natural gas is stored inside the protected tank body, the liquid level of the liquefied natural gas in the protected tank body is always balanced with the horizontal plane due to the effect of gravity, and the protected tank body is driven to rotate to cope with the swinging of the two sides of the hull, thereby preventing the protected tank body from causing safety accidents due to shaking in the device, effectively reducing the occurrence of vibration, and thus avoiding the possibility of collision of the protected tank body.
[0018] 2. The present application drives the rotating shaft through a rotating drive motor, the rotating shaft drives the third gear, the third gear drives the ring gear, so that the second gear is driven by the ring gear, the second gear drives all the driven shafts, thereby driving all the first gears, the first gear drives the rack, the rack is brought to the first sliding seat, and the first sliding seat drives the movement of the roller shaft, so that all the roller shafts can move along the slide grooves of the first fixed plate and the second fixed plate at the same time, making it convenient for all the roller shafts to clamp the protected tank body.
[0019] 3. The present application improves the connection strength between the first sliding seat and the second sliding seat by setting the connecting rod and the supporting frame, making the structure more stable and facilitating the roller to clamp the protected tank body.
[0020] 4. The present application can protect the outer wall of the protected tank body through the setting of the protective tube. When the roller clamps the protected tank body, the telescopic rod on the connecting rod, under the support of the first elastic member, makes the arc plate fit with the inner wall of the protective tube, thereby playing a shock-absorbing role for the protected tank body through the first elastic member. Through the setting of the arc plate, the connecting rod can better fit with the inner wall of the protective tube, thereby improving the shock-absorbing effect.
[0021] 5. The present application adopts the setting of the sleeve so that the arc plates on multiple connecting rods are sleeved together through the sleeve, so that the arc plates on multiple connecting rods are assembled into a ring-shaped frame, thereby improving the shock-absorbing effect of the arc plates, further suppressing the generation of vibration, and avoiding the occurrence of safety hazards.
[0022] 6. The present application reduces the generation of vibration and absorbs vibration by setting a buffer block and a second elastic member. By setting a third elastic member and a slider, the slider can support the buffer block, which can further improve the shock absorption effect. At the same time, multiple third elastic members can absorb vibration energy and improve the shock absorption effect.
[0023] 7. The present application can support the four end corners of the base through the provision of four buffer rods and the second elastic member, so that the base can slide more balancedly in the shock-absorbing box, and is not prone to getting stuck, while also improving the shock-absorbing effect.
[0024] 8. This application detects the sliding displacement distance through the setting of sensors.

[0045] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0046] like Figure 1-10 As shown, this application provides:
[0047] A LNG ship transport equipment with a tank protection function is applied to a hull 1. The hull 1 is provided with a plurality of mounting grooves 1a arranged in a rectangular array. A shock absorbing mechanism 2 is provided in all the mounting grooves 1a. The shock absorbing mechanism 2 includes a base 2a, a first fixing plate 2b, a second fixing plate 2c, a driving mechanism and a plurality of rollers 2g. The base 2a is a rectangular plate-shaped structure. The first fixing plate 2b and the second fixing plate 2c are both vertically disposed at both ends of the base 2a. The first fixing plate 2b and the second fixing plate 2c are both provided with through holes 2b1 that match the protected tank 3. The through holes 2b1 of the first fixing plate 2b and the second fixing plate 2c are disposed on the first fixing plate 2b and the second fixing plate 2c. b1 is sleeved with an annular shock-absorbing ring 2b2 made of elastic material, the driving mechanism is located on the first fixed plate 2b, and the first fixed plate 2b and the second fixed plate 2c are provided with a plurality of slide grooves 2b3 equidistantly surrounding the axis of the through hole 2b1, and all the slide grooves 2b3 are arranged along the edges of the first fixed plate 2b and the second fixed plate 2c toward the axis of the through hole 2b1, all the roller shafts 2g are horizontally located between the first fixed plate 2b and the second fixed plate 2c, both ends of all the roller shafts 2g are slidably matched with the slide grooves 2b3 on the first fixed plate 2b and the second fixed plate 2c respectively, and all the roller shafts 2g are transmission connected to the driving mechanism.
[0048] Based on the above embodiment, when liquefied natural gas is transported by transport ships, the conditions on the water surface are more complicated than when it is transported by land. When the hull 1 swings on both sides during transportation on the water surface, the shock absorbing mechanism 2 in the prior art can only suppress the vibration but cannot suppress the swinging of the hull 1, which may cause safety accidents. The technical problem that this application wants to solve is how to protect the protected tank body 3 on the transport ship. To this end, the present application inserts the protected tank body 3 storing liquefied natural gas into the through hole 2b1 of the first fixing plate 2b and the second fixing plate 2c. At this time, the protected tank body 3 is supported by the annular shock-absorbing ring 2b2 in the through hole 2b1 of the first fixing plate 2b and the second fixing plate 2c. The setting made of elastic material can suppress the shaking when running on the water surface, thereby achieving a shock-absorbing effect. When the hull 1 swings on both sides, due to the effect of gravity, the protected tank body 3 can only be tightly attached to the bottom of the through hole 2b1, and the shock-absorbing ring 2b2 is used to absorb the shock, but it cannot cope with the swing of the hull 1. The driving mechanism drives all the rollers 2g to move, so that the rollers 2g move along the direction of the slide groove 2b3, so that all the rollers 2g move along the edge of the first fixing plate 2b toward the axis of the through hole 2b1, until all the rollers 2g are in contact with the outer wall of the protected tank body 3, so that the protected tank body 3 is clamped by all the rollers 2g. On the upper part, the protected tank body 3 is clamped on the axis of the through hole 2b1 by multiple rollers 2g, and the protected tank body 3 can be driven to rotate within the multiple rollers 2g through the setting of multiple rollers 2g. Since liquefied natural gas is stored inside the protected tank body 3, the liquid level of the liquefied natural gas in the protected tank body 3 is always kept in balance with the horizontal plane due to the effect of gravity, thereby driving the protected tank body 3 to rotate to cope with the swinging of the hull 1 on both sides, thereby preventing the protected tank body 3 from causing safety accidents due to shaking in the device, effectively reducing the occurrence of vibrations, thereby avoiding the possibility of collision of the protected tank body 3. When the swinging stops, all rollers 2g are reset through the driving mechanism, thereby continuing to dampen the protected tank body 3 through the shock-absorbing ring 2b2. Through the setting of the shock-absorbing ring 2b2, the rollers 2g and the driving mechanism, the shock-absorbing mechanism 2 can cope with various vibrations or shaking occurring during transportation, thereby effectively avoiding the occurrence of safety accidents.
[0049] like Figure 4-7 and Fig.10 As shown, further:
[0050] Both ends of all roller shafts 2g are respectively sleeved with a first sliding seat 2g1 and a second sliding seat 2g3, which are respectively slidably matched with the sliding grooves 2b3 of the first fixed plate 2b and the second fixed plate 2c, and the tops of all first sliding seats 2g1 are fixedly connected with a rack 2g2 placed in a vertical state, and the sides of all racks 2g2 are provided with a driven shaft 2b5 in a horizontal rotation state, which passes through the first fixed plate 2b, and all driven shafts 2b5 are sleeved with a first gear 2b6 and a second gear 2b7, which are respectively located on both sides of the first fixed plate 2b, and the first gear 2b6 is meshed with the rack 2g2, and all second gears 2b7 are transmission connected with the driving mechanism.
[0051] Based on the above embodiments, the technical problem that the present application intends to solve is how the roller 2g slides in the slide groove 2b3 on the first fixed plate 2b and the second fixed plate 2c. To this end, the present application arranges the first sliding seat 2g1 and the second sliding seat 2g3 on both ends of the roller 2g, so that the roller 2g can be rotatably connected to the first sliding seat 2g1 and the second sliding seat 2g3, so that the roller 2g can rotate with the rotation of the protected tank 3. When the hull 1 swings, the driving mechanism drives all the second gears 2b7 connected to it to rotate, and the rotation of the second gear 2b7 drives the rotation of the driven shaft 2b5 connected to it, and the rotation of the driven shaft 2b5 drives the first gear connected to it. The rotation of 2b6 drives the rack 2g2 connected thereto to move through the first gear 2b6. Since the first sliding seat 2g1 slides with the slide groove 2b3 of the first fixed plate 2b, the movement of the rack 2g2 drives the movement of the first sliding seat 2g1 fixed thereto. The movement of the first sliding seat 2g1 drives the roller 2g connected thereto. The roller 2g drives the movement of the second sliding seat 2g3 on the other side, thereby realizing the movement of the roller 2g along the direction of the slide groove 2b3 of the first fixed plate 2b and the second fixed plate 2c.
[0052] like Figure 4-7 As shown, further:
[0053] The driving mechanism includes a ring gear 2f1, a rotating shaft 2f2, a third gear 2f3, a rotating drive motor 2f5 and a bracket 2f4. An annular slide rail 2b8 coaxial with the axis of the through hole 2b1 is arranged on the outer side of the through hole 2b1 of the first fixed plate 2b. The ring gear 2f1 is rotatably located on the annular slide rail 2b8. All second gears 2b7 are located on the periphery of the ring gear 2f1, and all second gears 2b7 are meshed and connected with the ring gear 2f1. The rotating shaft 2f2 is rotatably located between two driven shafts 2b5 in a horizontal rotation state, and the third gear 2f3 is sleeved on the rotating shaft 2f2. The third gear 2f3 is meshed and connected with the ring gear 2f1. The bracket 2f4 is located on the side of the first fixed plate 2b away from the roller shaft 2g. The rotating drive motor 2f5 is fixedly connected to the bracket 2f4, and the output shaft of the rotating drive motor 2f5 passes through the bracket 2f4 and is fixedly connected to the rotating shaft 2f2.
[0054] Based on the above embodiments, the technical problem that the present application aims to solve is how the driving mechanism drives the second gear 2b7 to rotate. To this end, the present application starts the rotary drive motor 2f5, and the output shaft of the rotary drive motor 2f5 drives the rotation of the rotary shaft 2f2 fixedly connected thereto, and the rotation of the rotary shaft 2f2 drives the rotation of the third gear 2f3 connected thereto, and the rotation of the third gear 2f3 drives the rotation of the ring gear 2f1 meshing with it, so that the ring gear 2f1 rotates in the annular slide rail 2b8, thereby driving the rotation of all the second gears 2b7 meshing with it through the ring gear 2f1, and driving all the driven shafts 2b5 through the second gear 2b7, thereby driving all the first gears 2b6, and the first gear 2b6 drives the rack 2g2, and the rack 2g2 is brought to the first sliding seat 2g1, and the first sliding seat 2g1 drives the movement of the roller 2g, so that all the rollers 2g can move along the slide groove 2b3 of the first fixed plate 2b and the second fixed plate 2c at the same time, so as to facilitate all the rollers 2g to clamp the protected tank body 3.
[0055] like Figure 4 and Fig.10 As shown, further:
[0056] The tops of the first sliding seat 2g1 and the second sliding seat 2g3 are fixedly connected by a connecting rod 2g4, and support frames 2g5 are provided at the connections between the two ends of the connecting rod 2g4 and the first sliding seat 2g1 and the second sliding seat 2g3.
[0057] Based on the above embodiments, the technical problem that the present application intends to solve is how to make the first sliding seat 2g1 and the second sliding seat 2g3 synchronously drive the roller 2g to move. To this end, the present application sets a connecting rod 2g4, so that the movement of the first sliding seat 2g1 can synchronously drive the movement of the second sliding seat 2g3, so that the roller 2g is conveniently driven by the first sliding seat 2g1 and the second sliding seat 2g3 to move along the slide groove 2b3 of the first fixed plate 2b and the second fixed plate 2c. The connection strength between the first sliding seat 2g1 and the second sliding seat 2g3 is improved by setting the support frame 2g5, so that the structure is more stable, and the roller 2g is convenient for clamping the protected tank body 3.
[0058] like Figure 3-4 and Fig.10 As shown, further:
[0059] A horizontally placed protective tube 2d is also provided between the first fixed plate 2b and the second fixed plate 2c. The protective tube 2d is a cylindrical tube structure with openings at both ends. The connecting rod 2g4 is provided with a plurality of telescopic rods 2g6 arranged along its length direction. The telescopic rods 2g6 are all vertically located on the connecting rod 2g4, and the telescopic rods 2g6 are all sleeved with a first elastic member 2g7. An arc plate 2g8 is provided on the top of all the telescopic rods 2g6, and the arc plate 2g8 matches the inner wall of the protective tube 2d.
[0060] Based on the above embodiments, the technical problem that the present application intends to solve is how to reduce shock while the roller 2g is clamping. To this end, the present application can protect the outer wall of the protected tank body 3 by setting the protective tube 2d. When the roller 2g clamps the protected tank body 3, the telescopic rod 2g6 on the connecting rod 2g4, supported by the first elastic member 2g7, makes the arc plate 2g8 fit with the inner wall of the protective tube 2d, thereby reducing shock to the protected tank body 3 through the first elastic member 2g7. The setting of the arc plate 2g8 makes the connecting rod 2g4 fit better with the inner wall of the protective tube 2d, thereby improving the effect of shock reduction.
[0061] like Fig.10 As shown, further:
[0062] A sleeve 2g9 is provided at one end of the arc-shaped plate 2g8, and the arc-shaped plates 2g8 on two adjacent connecting rods 2g4 can be sleeved together through the sleeve 2g9.
[0063] Based on the above embodiments, the technical problem that the present application intends to solve is how to improve the shock absorption effect of the arc plate 2g8. To this end, the present application sets a sleeve 2g9 so that the arc plates 2g8 on multiple connecting rods 2g4 are mutually sleeved together through the sleeve 2g9, so that the arc plates 2g8 on multiple connecting rods 2g4 are assembled into an annular frame, and the annular frame fits the inner wall of the protective tube 2d. When the hull 1 vibrates, the annular frame can improve the shock absorption effect of the arc plate 2g8, further suppress the generation of vibration, and avoid the occurrence of safety hazards.
[0064] like Figure 4 and Figure 6 As shown, further:
[0065] Support legs 2b4 are provided on both sides of the bottom of the first fixing plate 2b and the second fixing plate 2c.
[0066] Based on the above embodiments, the technical problem that the present application intends to solve is how to improve the supporting force of the first fixing plate 2b and the second fixing plate 2c on the base 2a. To this end, the present application can improve the connection strength of the first fixing plate 2b and the second fixing plate 2c on the base 2a by setting the supporting feet 2b4, and at the same time can increase more supporting force to prevent damage to the first fixing plate 2b and the second fixing plate 2c and improve the stability of the device.
[0067] like Figure 8 and Fig. 9 As shown, further:
[0068] A shock absorbing box 2e, a buffer block 2a1, a second elastic member 2a2, a plurality of sliders 2e2, a plurality of push rods 2e5 and a plurality of third elastic members 2e4 are also provided below the base 2a. The shock absorbing box 2e is a rectangular box body mechanism with an opening at the top. The shock absorbing box 2e is sleeved on the bottom of the base 2a. The buffer block 2a1 is a square plate-shaped structure. The buffer block 2a1 is fixedly connected to the center of the bottom of the base 2a in a horizontal state. The second elastic member 2a2 is located at the bottom of the buffer block 2a1 and the shock absorbing box 2e. The bottom of the shock absorbing box 2e is provided with a plurality of first slide rails 2e1 surrounding the center line thereof, and all the sliders 2e2 are slidably located on the first slide rails 2e1 in turn, one end of all the push rods 2e5 is pinned to the edge of the buffer block 2a1, and the other end of all the push rods 2e5 is pinned to the top of the slider 2e2, and all the sliders 2e2 are fixedly connected with a mounting plate 2e3 placed in a vertical state, and all the third elastic members 2e4 are respectively located between the mounting plate 2e3 and the inner side wall of the shock absorbing box 2e.
[0069] Based on the above embodiments, the technical problem that the present application intends to solve is how the shock absorbing mechanism 2 can suppress vibration. To this end, the present application sets the buffer block 2a1 and the second elastic member 2a2 so that the second elastic member 2a2 supports the base 2a, thereby reducing the vibration thereof and absorbing the vibration. Since the base 2a is sleeved in the shock absorbing box 2e, when the base 2a moves along the inner wall of the shock absorbing box 2e, the buffer block 2a1 is driven to move. The movement of the buffer block 2a1 drives the push rod 2e5 pinned thereto. The movement of the push rod 2e5 drives the movement of the slider 2e2 pinned thereto, so that the slider 2e2 moves along the direction of the first slide rail 2e1. Due to the setting of the third elastic member 2e4, the slider 2e2 can support the buffer block 2a1, which can further improve the shock absorbing effect. At the same time, the vibration can be absorbed by multiple third elastic members 2e4 to improve the shock absorbing effect.
[0070] like Figure 8 and Fig. 9 As shown, further:
[0071] Buffer rods 2a3 are vertically arranged at the four end corners of the base 2a. All buffer rods 2a3 pass through the base 2a. The buffer rods 2a3 are sleeved with fourth elastic members 2a4, and the fourth elastic members 2a4 are located between the base 2a and the shock absorbing box 2e.
[0072] Based on the above embodiment, the buffer block 2a1 is located in the center of the base 2a, which may cause the base 2a to get stuck when sliding in the shock absorbing box 2e, affecting the shock absorbing effect of the base 2a. The technical problem that this application wants to solve is how to better shock the base 2a. To this end, this application can support the four end corners of the base 2a through the arrangement of four buffer rods 2a3 and the second elastic member 2a2, so that the base 2a can slide in the shock absorbing box 2e more balanced, and it is not easy to cause the base 2a to get stuck, and at the same time, the shock absorbing effect can be improved.
[0073] like Figure 4 and Figure 8 As shown, further:
[0074] An alarm component 2h is also provided on the base 2a. The alarm component 2h includes an alarm 2h1 and sensors 2h2 corresponding in number to the sliders 2e2. All sensors 2h2 are fixedly connected to the multiple sliders 2e2 in sequence. The alarm 2h1 is located on the top of the base 2a.
[0075] Based on the above embodiments, the technical problem that the present application intends to solve is how the shock absorbing mechanism 2 can give an early warning to the staff. To this end, the present application detects the sliding displacement distance by setting the sensor 2h2. When the displacement of multiple sliders 2e2 exceeds the set threshold, an electrical signal is sent to the back-end controller, and the back-end controller sends an electrical signal to the alarm 2h1, so that the alarm 2h1 emits a buzzer or flashes a light, thereby giving an early warning and reminder to the staff to ensure that the protected tank 3 can be effectively protected.
[0076] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
