Description

Technical Field

[0001] The invention relates to the technical field of ship davits, in particular to a stable connecting rod type ship davit. Background Art

[0002] The davit is a special equipment carried by the ship for lifting and unloading lifeboats or workboats, referred to as "davit". It is usually located on both sides of the ship's deck, usually inside the ship's side, and extended out of the side when in use to lift or lower the boat. According to the different ways in which the davit can turn the boat from the inside to the outside, it can be divided into three types: turn-out type, tilt-over type and gravity type.

[0003] The davit is a special lifting device carried on the ship for lowering and lowering small boats. According to the different ways of lowering and retrieving the boats, it can be divided into three types: gravity type, swing-out type and roll-out type. The relevant specifications have strict provisions on the performance of the davit, including: the ability to quickly lower the boat to the water surface and retract it inboard, the strength of the davit and its accessories, when the ship is listed 15 degrees to either side and 5 degrees to either side and the speed is 5 knots, it can meet the requirements that the small boat can be turned outboard when carrying all equipment and two crew members, and then fully loaded with all passengers to safely land on the water surface on the horizontal cable of the davit, at least two safety ropes are set, and if a davit is installed, it is equipped with a safety device such as an limit switch, so that the davit can automatically cut off the power when it returns to the pecking position.

[0004] At present, when the existing davit is used to support the lifting of the boat, the boat will shake in the davit due to the shaking of the ship when it is running on the water surface, causing the steel cable to be damaged and broken due to the long-term shaking. Summary of the invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a stable connecting rod type ship davit, comprising a frame, the frame is used for stable support of the ship, the bottom ends of the frame are rotatably mounted with support seats, the top of the frame is mounted with a raised frame, two raised frames are provided, a motor is fixedly mounted between the opposite surfaces of the two raised frames, and a rotating shaft is rotatably mounted on the top of the raised frame; A stabilizing support assembly, which is used for shock absorption and protection of the davit, and the stabilizing support assembly is fixedly installed at the bottom of the frame; A bottom support assembly, which is used to support the bottom of the boat; The frame is fixedly mounted on the top of the support seat and the stabilizing support assembly, the stabilizing support assembly is fixedly mounted on the surface of the frame away from the support seat, and the bottom support assembly is fixedly mounted on the opposite surface assembly of the frame; the staff connects the boat to the hook through the steel cable, and then the staff starts the motor to rotate the motor to drive the steel cable to rotate so as to reel in the steel cable and lift the boat. At this time, the boat moves on the bottom support assembly as the steel cable is tightened, thereby supporting the bottom of the boat.

[0006] The bottom support assembly includes a frame plate, a side plate is fixedly installed on the surface of the frame plate, a support plate is fixedly installed on the bottom of the side plate, a guide is fixedly installed on the top of the frame plate, a support pad is fixedly installed on the top of the guide, and an end plate is fixedly installed on the outer surface of the support pad. The staff starts the motor to drive the pulley to rotate, and the steel cable rotates on the shaft to pull the boat upward and lift it. At this time, the front end of the boat contacts the end plate, so that the bottom of the boat slides along the end plate when it is lifted and generates friction with the support pad. Since the bottom of the boat is an arc-shaped structure, it adapts to the support pad when it is lifted and slid, so that the bottom of the boat slides along the support pad, so that the bottom of the boat is guided and supported when the boat is lifted.

[0007] Preferably, the frame plate is fixedly mounted on the surface of the frame, the end plate and the support pad are covered on the surface of the guide member, and the support pad is frictionally fitted with the guide member.

[0008] Preferably, the guide member includes a fixed plate, the fixed plate is fixedly mounted on the top of the frame plate, a round rod is fixedly mounted on the outer surface of the fixed plate, a curved plate is slidably mounted on the outer surface of the round rod, and the curved plate is adapted to the frame plate. The guide member is arranged below the support pad, and the guide member is arranged in an arc shape to adapt to the bottom of the boat. When the boat is lowered, the bottom of the boat slides downward along the support pad. When the boat slides down along the support pad to contact the round sleeve, the round sleeve and the curved shaft are squeezed by the bottom of the boat and move downward. At this time, the curved shaft drives the circular shaft to slide on the end of the round rod and squeezes the spring, so that the spring is squeezed and shrinks and slides on the surface of the circular shaft. At this time, the curved plate slides on the surface of the round rod to one side of the fixed plate, and guides and protects the bottom of the boat when the boat is lowered, so as to avoid deviation when the boat is lowered, and the boat swings on the davit, causing the steel cable to be damaged and broken due to long-term shaking.

[0009] Preferably, a spring is sleeved on the surface of the round rod away from the fixed plate, a round shaft is fixedly mounted on the outer surface of the spring, and a short rod is fixedly mounted on the lower surface of the round shaft. The bent plate is pushed by the spring and slides on the round rod. When the bent plate slides to the side of the fixed plate, the bent plate abuts against the side frame plate to limit the round shaft, so as to prevent the bottom of the boat from sliding and displacing on its surface when the bent shaft is loaded on the bottom of the boat, causing the bent shaft to be overstressed and deviate, thereby affecting the service life of the guide.

[0010] Preferably, a bent shaft is fixedly installed between opposite surfaces of the short rod, and a round sleeve is sleeved on the surface of the bent shaft, and the round sleeve is matched with the support pad.

[0011] Preferably, the stabilizing support assembly includes a bottom plate, a center block is fixedly installed inside the bottom plate, side plates are fixedly installed on both sides of the outer surface of the center block, and elastic members are fixedly installed on both sides of the outer surface of the side plates. Since the boat davit is arranged on both sides of the ship deck, the boat is supported on the top of the frame after being hoisted, and the stabilizing support assembly is supported on the bottom of the frame. When the boat shakes on the water, the frame squeezes the center block and the side plates, so that the elastic members in the side plates are squeezed and deformed to extend to both sides, so that the stabilizing support assembly is supported at the bottom of the frame with the frequency of the ship shaking, thereby preventing the boat from shaking in the bottom support assembly.

[0012] Preferably, two center blocks are provided, and the two center blocks are respectively fixedly installed between the bottom plate and the frame, and a damper is fixedly installed between the opposite surfaces of the center blocks.

[0013] Preferably, a support rod is provided inside the damper, and the support rod is fixedly installed on both sides of the outer surface of the damper, and the support rod passes through between opposite surfaces of the elastic pressure piece, and the elastic pressure piece is adapted to the side plate.

[0014] Preferably, the elastic member includes a clamping plate, which is fixedly mounted on both sides of the outer surface of the side plate, and the inner part of the clamping plate is slidably adapted to be provided with a clamping plate, which penetrates the clamping plate and extends to the outside thereof. When the ship is traveling on the water, it shakes on the water surface, so that the rack on the deck shakes with the ship. At this time, the rack presses down and causes the spring sheet to be squeezed and deformed, so that the spring sheet slides on the support rod in the direction of the hull shaking, so as to improve the stability of the boat placed on the davit after it is lifted, and to prevent the boat from colliding with the bottom support assembly due to the shaking of the ship, causing the boat to be damaged by the collision.

[0015] Preferably, the surfaces of the clamping plates are fixedly mounted with extension plates, and spring sheets are fixedly mounted between the opposite surfaces of the extension plates, and a round hole is opened inside the spring sheets, and the round hole is sleeved on the outer surface of the support rod. When the ship shakes, the frame rotates in the support seat, and the boat squeezes the frame, so that the middle blocks at both ends of the damping are squeezed and displaced to stably support the bottom of the frame. When the damping shrinks toward the middle, the clamping plate slides in the clamping plate and extends outward. When the damping stretches toward both ends, the two ends of the clamping plate are clamped in the clamping plate, so that the spring sheets are stretched and deformed and straightened. The support rod is supported between the spring sheets on both sides to maintain the balance of the spring sheets on both sides when they are deformed.

[0016] The present invention provides a stable connecting rod type ship davit, which has the following beneficial effects: 1. The stable connecting rod type ship davit is started by the staff to drive the pulley to rotate. At this time, the steel cable rotates on the shaft to pull the boat upward and lift it. At this time, the front end of the boat contacts the end plate, so that the bottom of the boat slides along the end plate when it is lifted and generates friction with the support pad. Since the bottom of the boat is an arc-shaped structure, it adapts to the support pad when it is lifted and slides, so that the bottom of the boat slides along the support pad, thereby guiding and supporting the bottom of the boat when it is lifted.

[0017] Second, the stable connecting rod type ship davit is arranged under the support pad through the guide member, and the guide member is arranged in an arc shape to match the bottom of the boat. When the boat is lowered, the bottom of the boat slides downward along the support pad. When the boat slides down along the support pad to contact the round sleeve, the round sleeve and the bent shaft are squeezed by the bottom of the boat and move downward. At this time, the bent shaft drives the round shaft to slide on the end of the round rod and squeezes the spring, so that the spring is squeezed and shrinks and slides on the surface of the round shaft. At this time, the bent plate slides on the surface of the round rod to one side of the fixed plate, and the bottom of the boat is guided and protected when the boat is lowered, so as to avoid deviation of the boat when it is lowered, and the boat swings on the davit, causing the steel cable to be damaged and broken due to long-term shaking.

[0018] 3. The stable connecting rod type ship davit is pushed by a spring through a bent plate and slides on a round rod. When the bent plate slides to one side of a fixed plate, the bent plate abuts against a side frame plate to limit the round shaft, thereby preventing the bottom of the boat from sliding and displacing on its surface when the bent shaft is loaded on the bottom of the boat, causing the bent shaft to be excessively stressed and deviated, thus affecting the service life of the guide.

[0019] Fourth, the stable connecting rod type ship davit is arranged on both sides of the ship deck. After the boat is lifted, it is supported on the top of the frame, and the stabilizing support assembly is supported on the bottom of the frame. When the ship shakes on the water surface, the frame squeezes the center block and the side plate, so that the elastic pressure parts in the side plate are squeezed and deformed to both sides, so that the stabilizing support assembly is supported at the bottom of the frame with the frequency of the ship shaking, thereby preventing the boat from shaking in the bottom support assembly.

[0020] 5. The stable connecting rod type ship davit, when the ship is traveling on the water, sways on the water surface, so that the rack on the deck sways with the ship. At this time, the rack presses down and squeezes and deforms the spring pieces, so that the spring pieces slide on the support rods in the direction of the hull swaying, so as to improve the stability of the boat placed on the davit after it is lifted, and avoid the boat from colliding with the bottom support assembly due to the swaying of the ship, causing the boat to be damaged by the collision.

At this time, the boat moves on the bottom support assembly 2 as the steel cable is tightened, thereby supporting the bottom of the boat.

[0025] The second embodiment is based on the first embodiment. Figures 1 to 8 As shown, the stabilizing assembly 6 includes a bottom plate 62, a center block 63 is fixedly installed inside the bottom plate 62, side plates 66 are fixedly installed on both sides of the outer surface of the center block 63, and spring-loaded parts 65 are fixedly installed on both sides of the outer surface of the side plates 66. Since the davits are arranged on both sides of the ship deck, the boat is supported on the top of the frame 5 after being hoisted, and the stabilizing assembly 6 is supported on the bottom of the frame 5. When the ship shakes on the water, the frame 5 squeezes the center block 63 and the side plates 66, so that the spring-loaded parts 65 in the side plates 66 are squeezed and deformed to extend to both sides, so that the stabilizing assembly 6 is supported at the bottom of the frame 5 with the frequency of the ship shaking, so as to prevent the boat from shaking in the bottom support assembly 2.

[0026] Two center blocks 63 are provided, and the two center blocks 63 are respectively fixedly installed between the bottom plate 62 and the frame 5 , and a damper 64 is fixedly installed between the opposite surfaces of the center blocks 63 .

[0027] A support rod 61 is disposed inside the damper 64 , and the support rod 61 is fixedly mounted on both sides of the outer surface of the damper 64 . The support rod 61 passes through the opposite surfaces of the spring-pressing member 65 , and the spring-pressing member 65 is matched with the side plate 66 .

[0028] The spring-pressing member 65 includes a clamping plate 651, which is fixedly mounted on both sides of the outer surface of the side plate 66. The inner sliding adaptor of the clamping plate 651 is provided with a clamping plate 652, which penetrates the clamping plate 651 and extends to the outside thereof. When the ship is traveling on the water, it shakes on the water, so that the frame 5 on the deck shakes with the ship. At this time, the frame 5 presses down and squeezes and deforms the spring sheet 653, so that the spring sheet 653 slides on the support rod 61 in the direction of the hull shaking, so as to improve the stability of the boat placed on the davit after being hoisted, and prevent the boat from shaking and colliding with the bottom support assembly 2 due to the shaking of the ship.

[0029] The surfaces of the clamping plates 652 are fixedly mounted with extension plates 655, and the opposite surfaces of the extension plates 655 are fixedly mounted with spring sheets 653, and the spring sheets 653 are provided with round holes 654 inside, and the round holes 654 are sleeved on the outer surface of the support rod 61. When the ship shakes, the frame 5 rotates in the support seat 1, and the boat squeezes the frame 5, so that the middle blocks 63 at both ends of the damper 64 are squeezed and displaced to stably support the bottom of the frame 5. When the damper 64 shrinks to the middle, the clamping plates 652 slide in the clamping plates 651 and extend outwards. When the damper 64 stretches to both ends, the two ends of the clamping plates 652 are clamped in the clamping plates 651, so that the spring sheets 653 are stretched and deformed and straightened, and the support rod 61 is supported between the spring sheets 653 on both sides to maintain the balance of the spring sheets 653 on both sides when they are deformed.

[0030] The third embodiment is based on the first and second embodiments. Figures 1 to 8 As shown, the bottom support assembly 2 includes a frame plate 26, a side plate 22 is fixedly mounted on the surface of the frame plate 26, a support plate 24 is fixedly mounted on the bottom of the side plate 22, a guide member 25 is fixedly mounted on the top of the frame plate 26, a support pad 21 is fixedly mounted on the top of the guide member 25, and an end plate 23 is fixedly mounted on the outer surface of the support pad 21. The staff starts the motor 3 to drive the pulley to rotate, and the steel cable rotates on the shaft 7 to pull the boat upward and lift it. At this time, the front end of the boat contacts the end plate 23, so that the bottom of the boat slides along the end plate 23 when it is lifted and generates friction with the support pad 21. Since the bottom of the boat is an arc-shaped structure, it is adapted to the support pad 21 when it is lifted and slid, so that the bottom of the boat slides along the support pad 21, so that the bottom of the boat is guided and supported when the boat is lifted.

[0031] The frame plate 26 is fixedly mounted on the surface of the frame 5 , the end plate 23 and the support pad 21 are covered on the surface of the guide member 25 , and the support pad 21 is frictionally fitted with the guide member 25 .

[0032] The guide member 25 includes a fixed plate 257 , which is fixedly mounted on the top of the frame plate 26 , a round rod 256 is fixedly mounted on the outer surface of the fixed plate 257 , a bent plate 258 is slidably mounted on the outer surface of the round rod 256 , and the bent plate 258 is adapted to the frame plate 26 . The guide member 25 is arranged below the support pad 21, and the guide member 25 is arranged in an arc shape to match the bottom of the boat. When the boat is lowered, the bottom of the boat slides downward along the support pad 21. When the boat slides down along the support pad 21 to contact the round sleeve 251, the round sleeve 251 and the bent shaft 254 are squeezed by the bottom of the boat and move downward. At this time, the bent shaft 254 drives the round shaft 252 to slide on the end of the round rod 256 and squeezes the spring 255, so that the spring 255 is squeezed and shrinks and slides on the surface of the round shaft 252. At this time, the bent plate 258 slides on the surface of the round rod 256 to the side of the fixed plate 257, and guides and protects the bottom of the boat when the boat is lowered, so as to avoid deviation of the boat when it is lowered, and the boat swings on the davit, causing the steel cable to be damaged and broken due to long-term shaking.

[0033] The surface of the round rod 256 away from the fixed plate 257 is sleeved with a spring 255, the outer surface of the spring 255 is fixedly mounted with a round shaft 252, and the lower surface of the round shaft 252 is fixedly mounted with a short rod 253. The bent plate 258 is pushed by the spring 255 and slides on the round rod 256. When the bent plate 258 slides to the side of the fixed plate 257, the bent plate 258 abuts against the side frame plate 26 to limit the round shaft 252, so as to prevent the bottom of the boat from sliding and displacing on its surface when the bent shaft 254 is carried on the bottom of the boat, causing the bent shaft 254 to be overstressed and deviate, thereby affecting the service life of the guide member 25.

[0034] A bent shaft 254 is fixedly installed between opposite surfaces of the short rod 253 . A round sleeve 251 is sleeved on the surface of the bent shaft 254 . The round sleeve 251 is matched with the support pad 21 .

[0035] When in use, the staff starts the motor 3 to make the motor 3 drive the pulley to rotate. At this time, the steel cable rotates on the rotating shaft 7 to pull the boat upward and lift it. At this time, the front end of the boat contacts the end plate 23, so that the bottom of the boat slides along the end plate 23 when it is lifted and generates friction with the support pad 21. Since the bottom of the boat is an arc-shaped structure, it adapts to the support pad 21 when it is lifted and slid, so that the bottom of the boat slides along the support pad 21, thereby guiding and supporting the bottom of the boat when it is lifted.

[0036] The guide member 25 is arranged below the support pad 21, and the guide member 25 is arranged in an arc shape to match the bottom of the boat. When the boat is lowered, the bottom of the boat slides downward along the support pad 21. When the boat slides down along the support pad 21 to contact the round sleeve 251, the round sleeve 251 and the bent shaft 254 are squeezed by the bottom of the boat and move downward. At this time, the bent shaft 254 drives the round shaft 252 to slide on the end of the round rod 256 and squeezes the spring 255, so that the spring 255 is squeezed and shrinks and slides on the surface of the round shaft 252. At this time, the bent plate 258 slides on the surface of the round rod 256 to the side of the fixed plate 257, and guides and protects the bottom of the boat when the boat is lowered, so as to avoid deviation of the boat when it is lowered, and the boat swings on the davit, causing the steel cable to be damaged and broken due to long-term shaking.

[0037] The bent plate 258 is pushed by the spring 255 and slides on the round rod 256. When the bent plate 258 slides to one side of the fixed plate 257, the bent plate 258 abuts against the side frame plate 26 to limit the round shaft 252, thereby preventing the bottom of the boat from sliding and displacing on its surface when the bent shaft 254 is carried on the bottom of the boat, causing the bent shaft 254 to be overstressed and deviate, thereby affecting the service life of the guide member 25.

[0038] Since the boat davits are arranged on both sides of the ship deck, the boat is supported on the top of the frame 5 after being lifted, and the stabilizing assembly 6 is supported on the bottom of the frame 5. When the ship rocks on the water, the frame 5 squeezes the center block 63 and the side plate 66, so that the spring-pressing member 65 in the side plate 66 is squeezed and deformed to extend to both sides, so that the stabilizing assembly 6 is supported on the bottom of the frame 5 with the frequency of the ship's rocking, thereby preventing the boat from rocking in the bottom support assembly 2.

[0039] When the ship is traveling on the water, it sways on the water, causing the frame 5 on the deck to sway with the ship. At this time, the frame 5 presses down and squeezes the spring piece 653 to deform, causing the spring piece 653 to slide on the support rod 61 in the direction of the hull swaying, so as to improve the stability of the boat placed on the davit after it is lifted, and to prevent the boat from colliding with the bottom support assembly 2 due to the swaying of the ship.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
