Description

Technical Field

[0001] This invention belongs to the field of lifeboat technology, and in particular relates to a guide boat mechanism for a freefall boat frame. Background Technology

[0002] The frame used for automatic descent lifeboats, such as the frame disclosed in the invention patent application No. 20162013566.3, consists of a bottom-fixed support frame and a flip-up lifting frame. The lifting frame is used to lift and move the lifeboat onto the support frame, while the support frame is used for storing the lifeboat and for releasing and guiding it during free fall.

[0003] The lifeboat lacks stability during the lifting and transfer to the support frame, making it prone to collisions and interference with the frame, which can easily damage the frame and the hull. It may also be difficult to position. Therefore, a guiding mechanism needs to be installed on the frame to guide the lifeboat and facilitate its lowering.

[0004] The existing guiding mechanisms are mainly divided into two types. The first type is a wheel structure that is set perpendicular to the landing direction of the boat frame. The second type consists of a guide plate and reinforcing ribs. In the guiding process, the hull and the guide plate of the second type are subject to sliding friction, which will still wear down the hull.

[0005] In addition to guiding the lifeboat during the descent, adjustments are needed to the fore-and-aft position after the lifeboat lands on the support frame for connection and positioning between the lifeboat and the release hook on the frame. Furthermore, as the lifeboat slides down along the support frame, the hull will still be in a state of sliding friction with the guiding mechanism, affecting the position adjustment and potentially causing instability of the guide plate and shortening the lifespan of the lifeboat. Summary of the Invention

[0006] The purpose of this invention is to provide a guide mechanism for a free-fall boat frame. By designing a conveyor belt-type guide mechanism installed on the side beam of the frame, it can provide vertical guidance for the lifeboat, which is beneficial for the positioning and landing of the lifeboat. At the same time, the guide frame can slide back and forth. When the lifeboat is adjusted back and forth on the frame, the guide frame slides along with it through friction. There is no sliding friction in the entire guiding process, which can protect the guide mechanism and the hull of the lifeboat, facilitate the landing and positioning of the lifeboat, and improve the service life.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] This invention relates to a boat guide mechanism for a freefall boat frame, comprising a boat guide frame, a sliding seat, and an extension pad fixed to the side beam of the boat frame;

[0009] The sliding seat is slidably mounted on the extension pad and the sliding direction is perpendicular to the length direction of the boat frame side beam. A set of slide rails parallel to the boat frame side beam is fixed on the top of the sliding seat. Sliding sleeves are provided on the outer side between the two ends of the two slide rails. A back plate is provided on the outer side of the extension pad. Two sets of locking holes are opened on the extension pad. A shrinkage space is formed between the locking holes and the back plate.

[0010] A push-pull cylinder is fixed to the outside of the back plate. The output end of the push-pull cylinder passes through the back plate and is fixed to the sliding seat through a fixed seat. Vertical holes are provided on both sides of the fixed seat. A locking cylinder is fixed to the top of the fixed seat. A set of locking pins is fixed to the output end of the locking cylinder through a support plate. The locking pins pass through the vertical holes and the lock opening in sequence.

[0011] The guide boat frame includes a base, and the bottom of the base is provided with sliding seats on both sides that slide with the two slide rails. A push block is fixed at the center of the bottom of the base, and an elastic mechanism is provided between the two sliding sleeves and the push block.

[0012] A set of side plates is fixed to the top of the base. The upper inner side of the side plate is provided with a sloping edge. The width of the sloping edge of the side plate increases from top to bottom. The lower inner side of the side plate is a vertical edge.

[0013] A plurality of pulleys are provided at the edge between a group of side plates, and a belt is externally connected to the pulleys. A plurality of inner support plates are fixed at the edge between the group of side plates. The inner support plates do not interfere with the pulleys, and the inner wall of the belt slides along the inner support plates.

[0014] Furthermore, the top of the extension pad is fixed with several sliding edges, which are perpendicular to the length direction of the side beam of the boat frame. The bottom surface of the sliding seat is in contact with the top surface of the extension pad, and the bottom of the sliding seat is provided with several sliding grooves that slide in cooperation with the sliding edges.

[0015] Furthermore, the outer side of the extension pad extends to the outer side of the boat frame side beam, and a number of first reinforcing ribs are fixed between the outer side of the extension pad and the boat frame side beam, and the positions of the number of first reinforcing ribs are misaligned with the two sets of locking holes.

[0016] Furthermore, several support wheels are fixed side by side on the inner side of the boat frame side beam, and the first reinforcing rib on the outer side of the extended pad and several support wheels do not interfere with each other.

[0017] Furthermore, the elastic mechanism includes a slide rod, one end of which is fixed to the push block, and the other end of which is slidably connected to the sliding sleeve. A return spring is provided outside the slide rod, and both ends of the return spring are movably connected to the push block and the sliding sleeve.

[0018] Furthermore, a limiting piece is fixed at the end of the slide rod away from the push block, and limiting seats are fixed at both ends of the slide rail.

[0019] Furthermore, both ends of the reset spring are fixed with end sleeves, which are slidably connected along the slide rod.

[0020] Furthermore, a reinforcing frame is provided on the side of the inner support plate away from the belt body, and the reinforcing frame is fixed between the two side plates.

[0021] Furthermore, a reinforcing plate is fixed to the outer side of the side plate by a set of stiffeners, the bottom of the reinforcing plate is fixed to the top of the base, and a second reinforcing rib is fixed between the outer side of the reinforcing plate and the base.

[0022] Furthermore, the outer surface of the belt is provided with several anti-slip textures.

[0023] The present invention has the following beneficial effects:

[0024] 1. This invention designs a conveyor belt-type lifeboat guide mechanism installed on the side beam of the lifeboat frame, which can provide vertical guidance for the lifeboat's landing, facilitating the positioning and landing of the lifeboat. At the same time, the lifeboat guide frame can slide back and forth. When the lifeboat is adjusted back and forth on the lifeboat frame, the lifeboat guide frame slides along with it through friction. There is no sliding friction during the entire lifeboat guiding process, which can protect the lifeboat guide mechanism and the hull of the lifeboat, facilitate the landing and positioning of the lifeboat, and improve its service life.

[0025] 2. This invention designs a guide frame that can slide a certain distance along the length of the side beam of the lifeboat frame. During the lifeboat's descent, the lifeboat will not move straight up and down relative to the side beam of the lifeboat frame, but will have a positional deviation. At this time, the sliding guide frame can slide along with the lifeboat hull, avoiding interference between the hull and the belt, and can protect the guide frame while maintaining stable guidance.

[0026] 3. The present invention provides an elastic mechanism in the sliding direction between the guide frame and the sliding seat, which can ensure that the guide frame has elasticity and sufficient distance for displacement in both the front and rear directions, thereby further improving the guiding stability of the guide mechanism.

[0027] 4. This invention installs the guide frame on a sliding and adjustable sliding seat. After the lifeboat is accurately lowered into the water and connected to the release hook on the frame, the guide frame can be controlled to move away from the lifeboat hull by pushing and pulling the hydraulic cylinder. This avoids interference between the lifeboat hull and the belt body during subsequent lifeboat descent, and will not obstruct the lifeboat, thus ensuring the stability and lifespan of the guide frame mechanism.

[0028] 5. This invention, through the cooperation of the locking port, locking pin, and locking cylinder, can realize the locking and unlocking between the sliding seat and the extension plate. At the same time, if there is a collision during the boat lowering process, the impact force is entirely borne by the fixed seat, locking port, and locking pin, and will not be transmitted to the locking cylinder and the push-pull cylinder, thus ensuring the service life of the two cylinders.

[0029] 6. The present invention provides inner support plates that fit against the inner wall of the belt on the inner side of the two side plates. The inner support plates will not affect the normal movement of the belt and can withstand the impact force caused by collisions during the boat drop process, thus ensuring the positional stability and service life of the boat guide frame.

[0030] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The bottom surface of the sliding seat 2 is in contact with the top surface of the extension pad 3, and the bottom of the sliding seat 2 is provided with several sliding grooves 203 that slide in cooperation with the sliding edges 309.

[0047] Among them, such as Figure 1 and Figure 3 As shown, the outer side of the extension pad 3 extends to the outer side of the boat frame side beam 4. Several first reinforcing ribs 310 are fixed between the outer side of the extension pad 3 and the boat frame side beam 4. The positions of the several first reinforcing ribs 310 and the two sets of locking holes 302 are misaligned.

[0048] Among them, such as Figure 1 and Figure 3 As shown, several support wheels 401 are fixed side by side on the inner side of the boat frame side beam 4, and the first reinforcing rib 310 on the outer side of the extension pad 3 and several support wheels 401 do not interfere with each other.

[0049] Among them, such as Figure 1-2 As shown, the elastic mechanism includes a slide rod 204. One end of the slide rod 204 is fixed to the push block 103, and the other end of the slide rod 204 is slidably connected to the sliding sleeve 202. A return spring 205 is provided on the outside of the slide rod 204, and the two ends of the return spring 205 are movably connected to the push block 103 and the sliding sleeve 202.

[0050] Among them, such as Figure 1-2 As shown, a limiting piece 206 is fixed at the end of the slide rod 204 away from the push block 103, and limiting seats 207 are fixed at both ends of the slide rail 201.

[0051] The return spring 205 has end sleeves fixed at both ends, and the end sleeves are slidably connected along the slide rod 204.

[0052] Among them, such as Figure 3 As shown, a number of inner support plates 107 are provided with a reinforcing frame 108 on the side away from the belt body 106, and the reinforcing frame 108 is fixed between the two side plates 104.

[0053] Among them, such as Figure 1-2 As shown, a reinforcing plate 110 is fixed to the outer side of the side plate 104 by a set of stiffening plates 109. The bottom of the reinforcing plate 110 is fixed to the top of the base 101, and a second reinforcing rib 111 is fixed between the outer side of the reinforcing plate 110 and the base 101.

[0054] Among them, the outer surface of the belt 106 is provided with several anti-slip textures.

[0055] Among them, such as Figure 5 As shown, the boat guide mechanism of the present invention is provided on both side beams 4 of the boat frame. The two boat guide mechanisms are symmetrically arranged, and the inner side of the side plate 104 on the two boat guide mechanisms forms an inverted V-shaped flare.

[0056] The working principle of this invention is as follows: the lifeboat is lifted and transferred to the top of the support frame of the lifeboat as the lifting frame on the lifeboat is lifted and the lifeboat is slowly lowered. The two sides of the lifeboat first come into contact with the upper inner side of the sloping edge of the side plate 104. Through the friction between the lifeboat and the belt 106, the belt 106 follows the transmission as the lifeboat is lowered until it lands on the support wheel 401 on the lifeboat frame.

[0057] When connecting the release hook at the stern of the lifeboat and the stern of the lifeboat frame, it is necessary to make forward and backward adjustments on the lifeboat frame support to ensure the connection with the release hook. During this process, the guide frame 1 slides along the slide rail 201 to avoid excessive friction causing displacement or damage to the belt 106 and making it difficult to adjust the position of the lifeboat.

[0058] After the lifeboat is connected to the release hook, the lifeboat's position is determined. The locking cylinder 306 is retracted, causing the locking pin 308 to disengage from the locking lug 302. At this time, the sliding seat 2 and the extension pad 3 are unlocked. The push-pull cylinder 303 is retracted, causing the sliding seat 2 and the guide frame 1 to move away from the lifeboat. This avoids the lifeboat from experiencing friction with the belt 106 on the guide frame 1 during subsequent descent, which could cause the belt 106 to shift, be damaged, or affect the lifeboat's free sliding.
