Description

Technical Field

[0001] The present invention relates to the technical field of scaffolding, and particularly to an assembled scaffolding for shipbuilding. Background Art

[0002] During the construction of ships and offshore platforms, from the initial sectional construction to the completion and delivery stage, scaffolding is an essential auxiliary tool. There are mainly three conventional ways to erect scaffolding during shipbuilding. The first is to completely use scaffolding steel pipes, connect them with special connectors, and erect a dense frame structure from the ground, and lay scaffolding mesh plates at the construction height. The second is to weld scaffolding eye plates, and then connect scaffolding tooling according to the requirements of the construction area and erect the construction platform layer by layer. The third is to weld scaffolding eye rings, use scaffolding hooks to connect, and erect the construction platform.

[0003] Traditional shipbuilding scaffolding mainly adopts spliced or welded beam structures, which not only consume a lot of materials, but also require the erection of multiple platforms. Construction personnel need to climb up and down, posing safety risks. Moreover, when constructing on the ship's side wall, in order to fit the arc-shaped side wall, the scaffolding needs to manufacture many pipe racks, roof plates and other components with suitable lengths, further increasing the material consumption, and the platform is fixed, making it difficult to lift up and down flexibly. Therefore, an assembled scaffolding for shipbuilding is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide an assembled scaffolding for shipbuilding to solve the problems of excessive material consumption, safety risks and difficult flexible lifting up and down of traditional shipbuilding scaffolding.

[0005] The present invention specifically adopts the following technical solutions to achieve the above purpose: An assembled scaffolding for shipbuilding, including a spliced scaffolding. A vertical rope ladder is arranged on one side of the spliced scaffolding. Two main hooks are fixedly installed at the top of the rope ladder. A plurality of evenly distributed fastening half-blocks are fixedly sleeved on both sides of the rope ladder. Two fastening half-blocks at the same position are symmetrically sleeved on the rope ladder. A fastening ear is fixedly installed on one side of each fastening half-block. Strong magnetic attraction plates are fixedly installed on a plurality of fastening half-blocks on the side far from the spliced scaffolding. A soft rubber pad is fixedly installed on one side of each strong magnetic attraction plate. First horizontal telescopic rods are rotatably installed on a plurality of fastening half-blocks on the other side. An activity sliding sleeve is fixedly installed at one end of each first horizontal telescopic rod close to the spliced scaffolding. The activity sliding sleeves are all slidably installed on the spliced scaffolding. A safety component is arranged at the bottom of the spliced scaffolding, and the safety component is used to cooperate with the rope ladder to ensure the safety of the activities of construction personnel.

[0006] Further, the safety component includes a winch fixedly installed at the bottom of the spliced scaffold. Two parallel safety ropes are wound on the winch. Fastening half rings and fastening frames are fixedly sleeved on both sides of the top and bottom ends of the rope ladder. The top ends of the two safety ropes respectively pass through the two fastening frames in sequence and are fixedly installed with threaded sleeves, and safety hooks are screwed on the threaded sleeves.

[0007] Further, safety sliders are slidably sleeved on the two safety ropes. Safety belts are fixedly installed on one side of each safety slider, and the same chest and back belt is fixedly installed between the two safety belts.

[0008] Further, first fastening electric push rods are fixedly installed on one side of each safety slider. The telescopic ends of the first fastening electric push rods extend into the interior of the safety slider and are fixedly installed with limiting pieces adapted to the safety ropes.

[0009] Further, two hanging straps are fixedly installed at the bottom of the chest and back belt. Pedal plates are fixedly installed at the bottom ends of the hanging straps, and multiple binding straps are fixedly installed on the pedal plates.

[0010] Further, a traction belt is fixedly installed at the bottom of the chest and back belt. The traction belt is located between the two hanging straps. A support chair is fixedly installed at the bottom end of the traction belt. A vertically arranged lifting slide rail is fixedly installed on one side of the spliced scaffold. A lifting slider is slidably installed inside the lifting slide rail. Multiple second horizontal telescopic rods are fixedly installed on the side of the lifting slider facing the support chair, and the telescopic ends of the second horizontal telescopic rods are fixedly installed on one side of the support chair.

[0011] Further, multiple evenly distributed clamping cutter bars are fixedly installed at the bottom of the pedal plates.

[0012] Further, accommodation grooves are formed on both sides of the lifting slider. Second fastening electric push rods arranged horizontally are fixedly installed inside the accommodation grooves. The telescopic ends of the two second fastening electric push rods are away from each other and are fixedly installed with brake pads.

[0013] The beneficial effects of the present invention are as follows: 1. By setting up a hanging rope ladder in the present invention, the rope ladder is hung on the ship's side. Multiple strong magnetic attraction plates adsorb and fix the rope ladder on the ship's side, enabling the rope ladder to be attached to the ship's side while remaining connected to the spliced scaffold, allowing construction workers to step on the rope ladder and move up and down flexibly, eliminating the need to manufacture numerous pipe racks, roof plates and other components of suitable lengths, thus saving the materials of the scaffold; 2. By setting up a chest and back strap, the construction worker can wear the chest and back strap under the armpits and on the chest and back. When the worker climbs to the designated position, the control button on the chest and back strap can be pressed, so that the first fastening electric push rod on one side of the safety sliding sleeve drives the internal limiting piece to lock the safety rope, so that the chest and back strap can play a role in safety limiting, and further prevent the risk of the worker falling during construction; 3. By setting up a support chair, after the worker wears the safety component, the support chair will always be at the position of the worker's buttocks under the traction of the traction belt and the guidance of the lifting slide rail, lifting slider and second horizontal telescopic rod, so that the construction worker can sit on the support chair. When the construction worker climbs on one side of the arc-shaped rope ladder for construction, the body will tilt backward, and the waist and back can be supported by the support chair, obtaining better construction conditions.

[0019] As Figures 1 to 9 shown, an assembled scaffolding for shipbuilding includes a spliced scaffolding 1. As Figure 1 、 Figure 2 shown, a vertically arranged rope ladder 2 is provided on one side of the spliced scaffolding 1. As Figure 3 shown, two main hooks 3 are fixedly installed at the top of the rope ladder 2. As Figure 4 、 Figure 5 shown, a plurality of uniformly distributed fastening half-blocks 4 are fixedly sleeved on both sides of the rope ladder 2. Two fastening half-blocks 4 at the same position are symmetrically sleeved on the rope ladder 2. A fastening ear 5 is fixedly installed on one side of each fastening half-block 4. A first horizontal telescopic rod 9 is rotatably installed on a plurality of fastening half-blocks 4 facing the spliced scaffolding 1. An active sliding sleeve 8 is fixedly installed at one end of the first horizontal telescopic rod 9 close to the spliced scaffolding 1. The active sliding sleeves 8 are all slidably installed on the spliced scaffolding 1.

[0020] In this embodiment, the spliced scaffolding 1 is composed of a plurality of vertical and horizontal steel pipes and other rods perpendicular to each other, special connectors, and platform mesh plates. Corresponding numbers of self-locking universal wheels can be assembled at the bottom of the spliced scaffolding 1 for moving the spliced scaffolding 1. The movable sliding sleeve 8 is slidably sleeved on the vertically distributed rods. The rope ladder 2 is divided into ropes on both sides and treads in the middle. The inside of the fastening half block 4 is a semi-circular three-through hole. After two fastening half blocks 4 are symmetrically sleeved, a complete hole is formed to accommodate the rope and one end of the tread together inside.

[0021] More specifically, when the assembled shipbuilding scaffolding is in use, first select the corresponding number of rods, special connectors, platform mesh plates and other leading components according to the height of the ship for splicing. While splicing, a plurality of movable sliding sleeves 8 are sequentially sleeved on the rods, and then the rods equipped with movable sliding sleeves 8 are assembled on two vertical columns at the middle position, so that the movable sliding sleeve 8 together with the first horizontal telescopic rod 9, the fastening half block 4 and the spliced scaffolding 1 are assembled together, thus assembling a spliced scaffolding 1 with suitable dimensions. Then take out the rope ladder 2 and place the rope ladder 2 on one side of two rows of fastening half blocks 4, and then sequentially screw the other half of the fastening half blocks 4 on the other side of the rope ladder 2, so that multiple groups of fastening half blocks 4 are respectively assembled on both sides of the rope ladder 2, thus assembling the rope ladder 2 and the spliced scaffolding 1 together, and at the same time enabling the rope ladder 2 to maintain its shaping ability.

[0022] A safety component is arranged at the bottom of the spliced scaffolding 1. The safety component is used to cooperate with the rope ladder 2 to ensure the safety of the construction personnel's activities, such as Figure 1 , Figure 2 As shown, specifically, the safety component includes a winch 10 fixedly installed at the bottom of the spliced scaffolding 1. Two parallel safety ropes 11 are wound on the winch 10. As Figure 3 shown, fastening half rings 12 and fastening frames 13 are fixedly sleeved on both the top and bottom sides of the rope ladder 2. The top ends of the two safety ropes 11 respectively pass through the two fastening frames 13 in sequence and are fixedly installed with threaded sleeves 14. Safety hooks 15 are screwed on the threaded sleeves 14.

[0023] More specifically, by setting the safety component, before the rope ladder 2 is adsorbed and hung on the ship's side, first control the winch 10 to unwind the two safety ropes 11, and then screw a pair of fastening half rings 12 and fastening frames 13 on both the top and bottom sides of the rope ladder 2, a total of four groups of fastening half rings 12 and fastening frames 13. Then pass one end of each of the two safety ropes 11 through the two fastening frames 13 on its respective side in sequence, and screw the two safety hooks 15 on the two threaded sleeves 14 respectively, and then buckle the two safety hooks 15 on structures such as steel frames, so that personnel can choose to grab the rope ladder 2 or the safety rope 11 to fix their bodies during construction, playing a dual anti-falling role.

[0024] AsFigure 6 , Figure 7 As shown in Figure 7 , specifically, safety sliders 16 are slidably sleeved on two safety ropes 11. Safety belts 17 are fixedly installed on one side of each safety slider 16. A same chest and back strap 18 is fixedly installed between the two safety belts 17. First fastening electric push rods 23 are fixedly installed on one side of each safety slider 16. The telescopic ends of the first fastening electric push rods 23 extend into the interior of the safety sliders 16 and are fixedly installed with limit pieces adapted to the safety ropes 11.

[0025] In this embodiment, in addition to the clamping knobs for controlling the tightness and length of the chest and back strap 18, control buttons for the first fastening electric push rods 23 on one side of the safety slider 16 and the second fastening electric push rods 29 inside the lifting sliders 27 are also provided on the chest and back strap 18.

[0026] More specifically, by providing the chest and back strap 18, before installing the safety ropes 11, first pass the two safety ropes 11 through the two fastening frames 13 at the bottom, then sleeved the two safety sliders 16 on the two safety ropes 11 respectively, and finally pass the two safety ropes 11 through the two fastening frames 13 at the top for installation. Then the construction workers can wear the chest and back strap 18 under the armpits and on the chest and back parts. When the personnel climb to the designated position, the control buttons on the chest and back strap 18 can be pressed to drive the limit pieces inside the first fastening electric push rods 23 on one side of the safety slider 16 to lock the safety ropes 11, so that the chest and back strap 18 can play a role in safety limit, further preventing the risk of personnel falling during construction.

[0027] As Figure 6 , Figure 8 shown, specifically, two hanging straps 19 are fixedly installed at the bottom of the chest and back strap 18. Pedal boards 20 are fixedly installed at the bottom ends of the hanging straps 19. A plurality of binding straps 21 are fixedly installed on each pedal board 20.

[0028] More specifically, by providing the pedal boards 20, after the personnel wear the chest and back strap 18, the two pedal boards 20 can be worn on the bottom of the feet by using the binding straps 21, so that the pedal boards 20 are connected to the chest and back strap 18 and the safety sliders 16 through the hanging straps 19, ensuring that the construction process will not be affected even if the personnel step on empty, and at the same time separating the patient's feet from the ship's side to prevent electric shock accidents during construction.

[0029] As Figure 8 shown, specifically, a plurality of evenly distributed clamping cutter bars 22 are fixedly installed at the bottom of each pedal board 20.

[0030] More specifically, by setting the clamping cutter bar 22, after the construction worker wears the footrest 20 and steps on the rope ladder 2 through the footrest 20, the clamping cutter bar 22 at the bottom of the footrest 20 can clamp the tread bar on the rope ladder 2, thus facilitating climbing and reducing the risk of stepping into thin air.

[0031] As Figure 5 shown, strong magnetic attraction plates 6 are fixedly installed on a plurality of fastening half blocks 4 located on the side far from the spliced scaffold 1, and soft rubber pads 7 are fixedly installed on one side of each strong magnetic attraction plate 6.

[0032] More specifically, the rope ladder 2 is hung on the ship's side, and the elastic deformation of the plurality of strong magnetic attraction plates 6 cooperating with the soft rubber pads 7 adsorbs and fixes the rope ladder 2 on the ship's side. Thus, while the rope ladder 2 remains connected to the spliced scaffold 1, it fits against the ship's side, and the main hook 3 at the top is hung on structural objects such as the steel frame and railing at the top of the ship's side, enabling the construction worker to step on the rope ladder 2 and move up and down flexibly, and using the safety components to ensure construction safety, without manufacturing numerous pipe racks, roof plates and other components of suitable lengths, saving the materials of the scaffold.

[0033] As Figure 1 、 Figure 6 shown, a traction belt 24 is fixedly installed at the bottom of the chest and back strap 18. The traction belt 24 is located between the two hanging straps 19. A support chair 25 is fixedly installed at the bottom end of the traction belt 24. A vertically arranged lifting slide rail 26 is fixedly installed on one side of the spliced scaffold 1. A lifting slider 27 is slidably installed inside the lifting slide rail 26. A plurality of second horizontal telescopic rods 28 are fixedly installed on the side of the lifting slider 27 facing the support chair 25, and the telescopic ends of the second horizontal telescopic rods 28 are all fixedly installed on one side of the support chair 25.

[0034] In this embodiment, the spliced scaffold 1 adopts fixing forms such as splicing, welding or screwing. The vertically arranged lifting slide rail 26 is composed of a plurality of short slide rails connected end to end up and down, and is respectively assembled on different rods.

[0035] More specifically, by setting the support chair 25, after the personnel wear the safety components, the support chair 25 will always be in the position of the personnel's buttocks under the traction of the traction belt 24 and the guidance of the lifting slide rail 26, the lifting slider 27 and the second horizontal telescopic rods 28, enabling the construction worker to sit on the support chair 25. When the construction worker climbs on one side of the arc-shaped rope ladder 2 for construction, the body will tilt backward, and the back can be supported by the support chair 25, obtaining better construction conditions.

[0036] As Figure 9As shown in the figure, specifically, accommodation grooves are formed on both sides of the lifting slider 27, and horizontally arranged second fastening electric push rods 29 are fixedly installed inside the accommodation grooves. The telescopic ends of the two second fastening electric push rods 29 are far away from each other and brake pads 30 are fixedly installed on them respectively.

[0037] More specifically, by setting the second fastening electric push rod 29, after the personnel lock the safety rope 11 by controlling the first fastening electric push rod 23 through a button, the second fastening electric push rods 29 on both sides inside the lifting slider 27 will respectively drive the two second fastening electric push rods 29 to move outwards and press against the inner walls on both sides of the lifting slide rail 26 for limiting, so as to fix the support chair 25 and support the personnel, thereby further improving the safety of the scaffolding during use.

[0038] In summary: When the assembled shipbuilding scaffold is in use, first select the corresponding number of rods, special connecting pieces, platform mesh plates and other leading components according to the height of the ship for splicing. While splicing, successively sleeve a plurality of movable sliding sleeves 8 on the rods, and then assemble the rods with the movable sliding sleeves 8 on the two vertical columns in the middle position, so that the movable sliding sleeves 8, together with the first horizontal telescopic rod 9, the fastening half block 4 and the spliced scaffold 1, are assembled together, thus assembling a spliced scaffold 1 with a suitable size. Then take out the rope ladder 2 and place the rope ladder 2 on one side of the two columns of fastening half blocks 4, and then successively screw the other half of the fastening half blocks 4 on the other side of the rope ladder 2, so that multiple groups of fastening half blocks 4 are respectively assembled on both sides of the rope ladder 2, thus assembling the rope ladder 2 with the spliced scaffold 1, and at the same time enabling the rope ladder 2 to maintain its shaping ability. After that, hang the rope ladder 2 on the ship's side, so that the multiple strong magnetic attraction plates 6 cooperate with the elastic deformation of the soft rubber pad 7 to adsorb and fix the rope ladder 2 on the ship's side, so that the rope ladder 2 is attached to the ship's side while remaining connected to the spliced scaffold 1, and hang the main hook 3 at the top on the steel frame, railing and other structures at the top of the ship's side. Then assemble the safety component with the rope ladder 2, so that the construction personnel can step on the rope ladder 2 to move up and down flexibly, and use the safety component to ensure construction safety. There is no need to manufacture many pipe racks, roof plates and other components with suitable lengths, saving the materials of the scaffold. By setting the safety component, before adsorbing and hanging the rope ladder 2 on the ship's side, first control the winch 10 to unwind the two safety ropes 11, and then screw a pair of fastening half rings 12 and fastening frames 13 on both sides of the top and bottom of the rope ladder 2 respectively, a total of four groups of fastening half rings 12 and fastening frames 13. Then pass one end of the two safety ropes 11 through the two fastening frames 13 on their respective sides in turn, and screw the two safety hooks 15 on the two threaded sleeves 14 respectively, and then buckle the two safety hooks 15 on the steel frame and other structures, so that the personnel can choose to grab the rope ladder 2 or the safety rope 11 to fix their bodies during construction, playing a dual anti-falling role. By setting the chest and back strap 18, before installing the safety rope 11, first pass the two safety ropes 11 through the two fastening frames 13 at the bottom, then sleeve the two safety sliding sleeves 16 on the two safety ropes 11 respectively, and finally pass the two safety ropes 11 through the two fastening frames 13 at the top for installation. Then the construction personnel can wear the chest and back strap 18 under the armpits and on the chest and back parts. When the personnel climb to the designated position, they can press the control button on the chest and back strap 18, so that the first fastening electric push rod 23 on one side of the safety sliding sleeve 16 drives the internal limiting piece to lock the safety rope 11, so that the chest and back strap 18 can play a role of safety limit, further preventing the risk of personnel falling during construction. By setting the footrest 20, after the personnel wear the chest and back strap 18, they can use the straps 21 to wear the two footrests 20 on the soles of their feet, so that the footrests 20 are connected to the chest and back strap 18 and the safety sliding sleeve 16 through the hanging straps 19, ensuring that the construction process will not be affected even if the personnel step on empty, and at the same time separating the patient's feet from the ship's side to prevent electric shock accidents during construction.By setting up the support chair 25, after the personnel wear the safety components, the support chair 25 will always be in the position of the personnel's buttocks under the traction of the traction belt 24 and the guidance of the lifting slide rail 26, the lifting slider 27, and the second horizontal telescopic rod 28, enabling the construction personnel to sit on the support chair 25. When the construction personnel climb on one side of the arc-shaped rope ladder 2 for construction, the body will tilt backward, and their waist and back can be supported by the support chair 25, obtaining better construction conditions. By setting up the positioning cutter bar 22, after the construction personnel wear the footrest 20, when they step on the rope ladder 2 through the footrest 20, the positioning cutter bar 22 at the bottom of the footrest 20 can hold the tread bar on the rope ladder 2, thus facilitating climbing and reducing the risk of stepping on air. By setting up the second fastening electric push rod 29, after the personnel lock the safety rope 11 by controlling the first fastening electric push rod 23 through a button, the second fastening electric push rods 29 on both sides inside the lifting slider 27 will respectively drive the two second fastening electric push rods 29 to move outward and press against the inner walls on both sides of the lifting slide rail 26 for limiting, thereby fixing the support chair 25 and supporting the personnel, thus further improving the safety of the scaffolding during use.,
