Description

Technical Field

[0001] This utility model relates to the field of boarding equipment technology, specifically a safe and quick boarding device for personnel in ports. Background Technology

[0002] When a ship needs repair or people need to board, boarding devices are often used. Generally, people place one end of a ladder on the shore and the other on the ship, and then board directly. This method of boarding will sway as the ship moves on the sea, making it very unsafe for people to board.

[0003] According to a search report from a novelty search agency, announcement number CN214029059U discloses a safe and quick boarding device for personnel in ports. This device includes a counterweight, a rotating plate fixedly mounted on the top of the counterweight, a housing fixedly mounted on the rotating plate, a sliding plate slidably disposed within the housing, sliding grooves on both inner walls of the housing, and multiple springs fixedly mounted on one inner wall of the housing. A common connecting plate is fixedly mounted on each of the multiple springs. This device minimizes the impact on the boarding ladder when people board ships, facilitating use by boarding personnel and effectively protecting their safety.

[0004] The aforementioned technology discloses a safe and quick boarding device for port personnel, which can reduce the impact on the boarding ladder. However, it still has the following shortcomings in use: the length of its boarding ladder and guardrail is fixed and cannot be extended or adjusted. Due to the different side buffer structures of different types of ships, the distance between the ship and the port location when it is moored is different. When the distance is large, the ship may separate due to insufficient length, making it unsafe to pass through this location. It is difficult to apply to different types of ships for safe boarding work, and its applicability is not ideal. In view of this, this application proposes a safe and quick boarding device for port personnel to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a safe and quick boarding device for personnel in ports, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safe and quick boarding device for personnel in a port, comprising two electric slide rails, with a fixed base fixedly connected to the bottom of each electric slide rail, and a movable base fixedly connected to the adjacent side of each of the two electric slide rails, with a rotating sleeve rotatably installed between the two movable bases; the two electric slide rails are used to drive the rotating sleeve to raise and lower to adjust the operating height through the two movable bases.

[0007] A telescopic boarding support assembly for supporting personnel boarding the ship is fixedly installed on the left side of the rotating sleeve. Telescopic barrier assemblies for protection are fixedly connected to the top front and top rear sides of the telescopic boarding support assembly. A pull-out tilt adjustment assembly fixedly connected to the corresponding telescopic barrier assembly is installed on the top of the electric slide rail. The telescopic boarding support assembly is used to adjust the height of the rotating sleeve by raising and lowering it together, and to adjust the length of the support for personnel to pass through according to the distance between it and different ship hulls, so as to accommodate the phenomenon that different types of ship hulls have different spacing when parked. The telescopic barrier assembly is used to prevent falling on the front and rear sides, and to adjust the length of the barrier as the length of the telescopic barrier assembly changes. The pull-out tilt adjustment assembly is used to further adjust the tilt of the telescopic boarding support assembly through the telescopic barrier assembly when the ship hull is high.

[0008] Preferably, the telescopic boarding support assembly includes a box-shaped carrier plate fixedly connected to the left side of the rotating sleeve. An expansion carrier plate is slidably sleeved inside the box-shaped carrier plate. The left side of the expansion carrier plate extends outside the box-shaped carrier plate. A limit baffle is fixedly connected to the bottom left side of the expansion carrier plate. A rectangular groove with openings on both the front and rear sides is opened on the bottom left side of the expansion carrier plate. Multiple anti-wear rollers are rotatably installed on the top inner wall of the rectangular groove. A transverse sliding seat is fixedly connected to the bottom right side of the expansion carrier plate. The bottom of the transverse sliding seat extends below the box-shaped carrier plate. A multi-stage electric telescopic rod with its protruding end fixedly connected to the right side of the transverse sliding seat is fixedly installed on the bottom right side of the box-shaped carrier plate.

[0009] Preferably, the telescopic barrier assembly includes a horizontal barrier tube, and multiple first support rods are fixedly connected to the top front side and top rear side of the box-shaped carrier plate. The bottom of the horizontal barrier tube is fixedly connected to the top of the corresponding multiple first support rods. A horizontal barrier bar is slidably sleeved inside the horizontal barrier tube. A second support rod is fixedly connected to the bottom left side of the horizontal barrier bar, and the bottom end of the second support rod is fixedly connected to the top left side of the expansion carrier plate.

[0010] Preferably, the pull-out tilting adjustment assembly includes a fixed pulley rotatably installed on the top left side of the corresponding electric slide rail. An annular anti-detachment groove is provided on the outer side of the fixed pulley. An electric hoist is fixedly installed on the top right side of the electric slide rail. One end of the wire rope of the electric hoist passes around the inner side of the corresponding annular anti-detachment groove and is fixedly installed with a fixing ring. The fixing ring is welded and fixed to the top of the corresponding crossbar.

[0011] Preferably, a first synchronous control switch and a second synchronous control switch are fixedly installed on the right side of the electric slide rail located at the rear. Both electric slide rails are electrically connected to the first synchronous control switch, and both electric hoists are electrically connected to the second synchronous control switch.

[0013] Preferably, a limiting hole is provided on the bottom inner wall of the box-shaped carrier plate, and the front and rear sides of the transverse sliding seat slide in contact with the front and rear inner walls of the limiting hole, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Through the combination of electric slide rails, moving seats, rotating sleeves, telescopic boarding support components, telescopic barrier components, and pull-out tilt adjustment components, the height and tilt of the box-shaped carrier plate can be flexibly adjusted according to the hull height of different vessels, making it convenient for boarding vessels of different heights.

[0016] 2. The telescopic boarding support assembly can be flexibly extended and adjusted to accommodate different types of ships with varying spacing, thus preventing accidental falls due to insufficient length and improving applicability.

[0017] 3. By combining the telescopic boarding support assembly and the telescopic barrier assembly, the barrier length can be automatically adjusted and the barrier can be used to prevent people from falling when the support length is increased or increased, thereby reducing the risk of people falling due to shaking and improving passage safety.

[0018] This utility model incorporates a series of structures that allow for flexible adjustment of the height and inclination of the box-shaped carrier plate according to the different heights of the hull. This facilitates boarding for hulls of varying heights and allows for flexible adjustment of the support length for personnel passage, adapting to different types of hulls with varying spacing. This prevents accidental falls due to insufficient length, improving applicability. Furthermore, when the support length is increased or adjusted, the guardrail length is automatically adjusted to prevent falls, reducing the risk of accidental falls due to swaying and improving passage safety.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown in the figure, this embodiment proposes a safe and quick boarding device for port personnel, including two electric slide rails 1. A fixed base is fixedly connected to the bottom of each electric slide rail 1. Movable seats 2 are fixedly connected to the adjacent sides of the moving ends of the two electric slide rails 1. A rotating sleeve 3 is rotatably installed between the two movable seats 2. A support shaft is fixedly connected between the adjacent sides of the two movable seats 2. Two bearings are fixedly fitted inside the rotating sleeve 3, with the inner rings of the bearings fixedly fitted to the outer sides of the support shaft, thus achieving the effect of rotating the rotating sleeve 3. A single, inclined ladder is fixedly connected to the right side of the two movable seats 2, and the ramp is designed for personnel to climb to the rotating sleeve 3. The two electric slide rails 1 are used to drive the rotating sleeve 3 to adjust its height via the two movable seats 2.

[0026] A telescopic boarding support assembly for supporting personnel boarding the ship is fixedly installed on the left side of the rotating sleeve 3. Telescopic barrier assemblies for protection are fixedly connected to the top front and top rear sides of the telescopic boarding support assembly. A pull-out tilt adjustment assembly fixedly connected to the corresponding telescopic barrier assembly is installed on the top of the electric slide rail 1. The telescopic boarding support assembly is used to adjust the height of the rotating sleeve 3 by raising and lowering it together, and is used to adjust the length of the support for personnel to pass through according to the distance between it and different ship hulls, so as to accommodate the phenomenon that different types of ship hulls have different spacing when they are parked. The telescopic barrier assembly is used to prevent falling on the front and rear sides, and is used to adjust the length of the barrier by raising and lowering it together when the length of the telescopic barrier assembly changes. The pull-out tilt adjustment assembly is used to further adjust the tilt of the telescopic boarding support assembly through the telescopic barrier assembly when the ship hull is high.

[0027] Specifically, the telescopic boarding support assembly includes a box-shaped carrier plate 4 fixedly connected to the left side of the rotating sleeve 3. An expansion carrier plate 401 is slidably fitted inside the box-shaped carrier plate 4. The left side of the expansion carrier plate 401 extends outside the box-shaped carrier plate 4. A limit baffle 405 is fixedly connected to the bottom left side of the expansion carrier plate 401. A rectangular groove with openings on both the front and rear sides is opened on the bottom left side of the expansion carrier plate 401. Multiple anti-wear rollers 404 are rotatably installed on the top inner wall of the rectangular groove. A transverse sliding seat 402 is fixedly connected to the bottom right side of the expansion carrier plate 401. The bottom of 02 extends to the bottom of the box-shaped carrier plate 4. A limiting hole 406 is provided on the inner wall of the bottom of the box-shaped carrier plate 4. The front and rear sides of the transverse shift seat 402 slide in contact with the inner walls of the front and rear sides of the limiting hole 406, respectively, allowing the transverse shift seat 402 to pass through and limiting its movement to prevent it from detaching. A multi-stage electric telescopic rod 403 with its extended end fixedly connected to the right side of the transverse shift seat 402 is fixedly installed on the bottom right side of the box-shaped carrier plate 4. The box-shaped carrier plate 4, the expanded carrier plate 401, the limiting baffle 405, the anti-wear roller 404, and the transverse shift seat 402 are all included. In conjunction with the multi-stage electric telescopic mast 403, the rotating sleeve 3 raises and lowers, driving the box-shaped carrier plate 4 to adjust the operating height. When the width of the side anti-collision structure of different types of hulls results in different distances from the port location, the multi-stage electric telescopic mast 403 can drive the transverse sliding seat 402 to move left and right, causing it to move the extended carrier plate 401 left and right. When the extended carrier plate 401 moves to the left, it can further extend the support length, achieving the effect of flexibly adjusting the support length according to the distance between different hulls, so as to accommodate different types of hulls with different spacing when moored. To prevent accidental falls due to insufficient length and gaps, the transverse shift seat 402 can be pre-lengthened and then lowered to engage with the hull body, allowing the anti-wear roller 404 at the bottom of the expansion plate 401 to contact the top of the hull. This further prevents separation risks and improves safety. Furthermore, the rotatable anti-wear roller 404 can rotate due to friction when the hull floats slightly from side to side, reducing relative friction.

[0028] Furthermore, the telescopic barrier assembly includes a horizontal barrier tube 501. Multiple first support rods 5 are fixedly connected to the top front and top rear sides of the box-shaped carrier plate 4. The bottom of the horizontal barrier tube 501 is fixedly connected to the top of the corresponding multiple first support rods 5. A horizontal barrier rod 502 is slidably fitted inside the horizontal barrier tube 501. A second support rod 503 is fixedly connected to the bottom left side of the horizontal barrier rod 502. The bottom end of the second support rod 503 is fixedly connected to the top left side of the expanded carrier plate 401. The horizontal barrier tube 501, first support rods 5, horizontal barrier rod 502, and second support rod 503 work together to provide barrier protection and prevent falls for personnel on the front and rear sides. When the expanded carrier plate 401 moves left and right, the two second support rods 503 drive the two horizontal barrier rods 502 to slide left and right within the corresponding horizontal barrier tube 501, thus adjusting the barrier length as a whole. This ensures that the front and rear sides are always in a barrier state during passage, guaranteeing safe passage.

[0029] Furthermore, the inclined adjustment assembly includes a fixed pulley 603 rotatably mounted on the top left side of the corresponding electric slide rail 1. An annular anti-detachment groove is provided on the outer side of the fixed pulley 603. An electric hoist 6 is fixedly mounted on the top right side of the electric slide rail 1. One end of the wire rope 601 of the electric hoist 6 passes over the inner side of the corresponding annular anti-detachment groove and is fixedly mounted with a fixing ring 602. The fixing ring 602 is welded and fixed to the top of the corresponding crossbar 501. The fixed pulley 603, annular anti-detachment groove, electric hoist 6, wire rope 601, and fixing ring 602 work together to utilize the electric hoist 6's own wire rope... Rope 601 lowers or raises the corresponding fixing ring 602. The fixing ring 602 lowers or raises the box-shaped carrier plate 4 through the corresponding horizontal bar 501 and the first support rod 5. When lowering, the box-shaped carrier plate 4 rotates and tilts downward. When raising, it pulls the box-shaped carrier plate 4 to rotate and tilt upward. This achieves the effect of further adjusting the inclination of the box-shaped carrier plate 4 through the telescopic bar assembly when the hull is high. In addition, by means of tilt adjustment, when the box-shaped carrier plate 4 is tilted due to the adjustment of the rotating sleeve 3 by the electric slide rail 1, it can also be adjusted to be used horizontally by lowering or raising the wire rope 601. It has high flexibility of use.

[0030] Furthermore, a first synchronous control switch and a second synchronous control switch are fixedly installed on the right side of the electric slide rail 1 located at the rear. Both electric slide rails 1 are electrically connected to the first synchronous control switch, and both electric hoist elevators 6 are electrically connected to the second synchronous control switch, so as to facilitate personnel to synchronously open and close the two electric slide rails 1 or the two electric hoist elevators 6.

[0031] The usage method of this embodiment is as follows: Two fixed seats are installed and fixed at the port boarding position. When the height of the box-shaped carrier plate 4 needs to be adjusted according to the height of the ship, the two electric slide rails 1 are activated to drive the rotating sleeve 3 to rise or fall via the two moving seats 2. The rotating sleeve 3 drives the box-shaped carrier plate 4 to rise and fall to adjust the height. When the inclination of the box-shaped carrier plate 4 needs further adjustment, personnel activate the two electric hoists 6, which lower or raise the corresponding fixed rings 602 via their own wire ropes 601. The fixed rings 602 pass sequentially through the corresponding crossbar 501 and the first support rod 5. When lowering or raising the box-shaped carrier plate 4, the box-shaped carrier plate 4 rotates and tilts downwards during lowering and is pulled upwards and tilted during raising. This allows for further adjustment of the tilt of the box-shaped carrier plate 4 by means of the telescopic barrier assembly when the hull is high. In addition, by means of the tilt adjustment, when the box-shaped carrier plate 4 is tilted due to the lifting and lowering adjustment of the rotating sleeve 3 by the electric slide rail 1, it can also be adjusted to be used horizontally by means of the lowering or raising of the wire rope 601. It has high flexibility of use. With the combination of height and tilt adjustment, it is convenient to use for boarding hulls of different heights.

[0032] Activating the multi-stage electric telescopic rod 403 drives the transverse sliding seat 402 to the left. The transverse sliding seat 402 then moves the expansion plate 401 to the left. As the expansion plate 401 moves to the left, it further expands the support length, achieving flexible adjustment of the support length based on the distance to different hulls. This accommodates different types of hulls with varying spacing, preventing accidental falls due to insufficient length and improving applicability. Alternatively, it can be pre-lengthened and then lowered to engage the transverse sliding seat 402 within the hull, allowing the expansion plate 401 to move to the left. The bottom anti-wear roller 404 contacts the top of the hull, which further prevents the risk of separation and improves safety. The anti-wear roller 404 is rotatable, and when the hull floats slightly from side to side, it can be driven to rotate by friction. The rotation of the anti-wear roller 404 reduces the relative friction and reduces the impact of the hull's swaying. When floating upward, the flexible steel wire rope 601 can bend and move. When pushed by the hull, the expansion plate 401 can adaptively tilt upward slightly to avoid hard impact.

[0033] When the expansion plate 401 moves left and right, the two second support rods 503 drive the two horizontal rails 502 to slide left and right within the corresponding horizontal rail tubes 501, thus adjusting the length of the guardrail as a whole. The two horizontal rail tubes 501 and the two horizontal rails 502 provide protection for personnel from falling by blocking them from the front and rear sides. This achieves the effect of automatically adjusting the length of the guardrail when the expansion plate is adjusted, reducing the risk of personnel falling due to shaking and improving passage safety. At this time, personnel can climb onto the box-shaped plate 4 via the ladder and then climb onto the hull via the expansion plate 401 to achieve safe boarding.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
