When the guardrail is damaged, the guardrail needs to be repaired by returning to the port, welding equipment is used, replaced materials need to be bought again, and a large amount of time and manpower and material resources are consumed. For example, when a pilot ship requires to convey a pilot closely to a ship, severe rolling can be generated when the pilot ship approaches the ship, a guardrail of the pilot ship inevitably collides or rubs with the ship, and the guardrail is easy to deform or damage, however, the pilot ship needs to be ready for 24 hours to receive and convey the pilot at any time, and the original receiving and conveying task is disturbed by the maintenance of the pilot ship during the outage, so that the cargo loading and unloading progress of the ship is directly influenced, and the construction period is delayed and the economic loss is caused. Therefore, even if the guardrail on the ship is damaged, the guardrail cannot be immediately returned to a port for maintenance, and the operation can bring operation safety hidden trouble to a crew in the case;

(2) guard rails are swingably provided on the deck of the ship to provide a buffering force when a collision with the ship occurs. However, when a ship collides with a large ship, the ship is shaken vigorously, and a crew usually grasps the guardrail as a handrail, and if the guardrail swings violently left and right, the crew may have a risk of falling into the water, and thus the crew cannot ensure the safety of the crew.

Fig. 1 shows a schematic structural view of the guardrail for a ship provided by this embodiment in a first state, and fig. 2 shows a schematic structural view of the guardrail for a ship provided by this embodiment in an extreme bending position. The marine guardrail on the existing part of ships is usually directly welded and fixed on the ships, when the ship collides to cause the damage of the marine guardrail, if the ship is repaired in time, the construction period is delayed and the economic loss is caused, and if the ship is not repaired in time, the potential safety hazard is brought to crews. In order to solve the above problem, referring to fig. 1 and 2, the present embodiment provides a guardrail for a ship, which includes a base 1 and a protection component 2, wherein the protection component 2 is swingably disposed on the base 1. When boats and ships bump, protection component 2 swings for base 1, can provide certain buffering effort for boats and ships, prevents that this marine guardrail from causing the damage because of the collision.

It can be understood that when the ship collides to cause severe shaking, the crew usually holds the protection component 2 as the armrest, but since the protection component 2 is swingably disposed on the base 1, the protection component 2 may fall to the outside of the ship in case of severe shaking, in which case the crew may have a risk of falling, and thus the safety of the crew cannot be ensured.

In order to prevent the ship from falling to the outside and improve the safety of the guardrail for the ship, as shown in fig. 1, the guardrail for the ship further comprises an outside limiting mechanism 3, the outside limiting mechanism 3 is arranged on the outside of the protection component 2, and the outside limiting mechanism 3 is configured to limit the swinging direction of the protection component 2 so that the protection component 2 can only swing towards the inside. Through this kind of mode of setting, when boats and ships bump and acutely rock, the crewman uses protection component 2 to grab for the handrail and holds up, can prevent that the crewman from grabbing the in-process and weighing down, has guaranteed crewman's safety.

Further, referring to fig. 1, a detailed structure of the protection component 2 is described in detail, as shown in fig. 1, the protection component 2 includes a connecting member 21 and a pillar 22, the connecting member 21 includes a fixing portion 211 and a bending portion 212 connected to each other, the fixing portion 211 is disposed on the base 1, and the bending portion 212 can swing relative to the fixing portion 211; the pillar 22 is disposed at an end of the bending portion 212 away from the fixing portion 211. Preferably, the base 1 is provided with a first accommodating hole, the upright column 22 is provided with a second accommodating hole, one end of the fixing portion 211, which is far away from the bending portion 212, is inserted into the first accommodating hole, and one end of the bending portion 212, which is far away from the fixing portion 211, is inserted into the second accommodating hole, so that stable connection among the base 1, the connecting member 21 and the upright column 22 is realized. When the ship collides, the fixing portion 211 is always in a vertical position, and the bending portion 212 drives the upright post 22 to swing inward relative to the fixing portion 211. This kind of setting mode is connected stably and easy dismounting, when connecting piece 21 takes place to damage, can demolish it from base 1 and stand 22 and change new connecting piece 21, saves cost of maintenance, convenient and fast, and when boats and ships bump, stand 22 can be along with kink 212 towards inboard swing, provides certain buffering effort.

The arrangement mode can save the link of assembling among a plurality of parts during processing, is more firm and durable in structure, is more convenient and quicker to install, and reduces the use of installation parts, thereby reducing the whole weight of the marine guardrail. In this embodiment, the elastic material is preferably rubber. The rubber has high hardness, and the connecting piece 21 is in a vertical state and can be used as a walkway handrail of a ship under the condition of no collision; secondly, the plasticity of rubber is stronger, and when boats and ships bump, the marine guardrail can be towards the inboard swing, has avoided causing this marine guardrail to damage when bumping with other boats and ships, and after the collision, this marine guardrail can resume the vertical state again. In addition, the elasticity of rubber is better, can hug closely in the inner wall of first holding hole and the inner wall of second holding hole through the elastic force of self in base 1 and stand 22 in the grafting back, and fixed effect is better. In other embodiments, the connecting member 21 may be a spring with appropriate strength, ABS resin, or polyurethane, which can also achieve the above-mentioned effects.

Further, as shown in fig. 1 and fig. 2, the bending portion 212 has a first state and a second state, when the bending portion 212 is in the first state, the axial direction of the bending portion 212 coincides with the axial direction of the fixing portion 211, and when the bending portion 212 is in the second state, the axial direction of the bending portion 212 forms an included angle with the axial direction of the fixing portion 211; the outer limiting mechanism 3 comprises a fixed limiting plate 31 and a movable limiting plate 32, the lower end of the fixed limiting plate 31 is connected with the base 1, the upper end of the movable limiting plate 32 is connected with the bending part 212, and the movable limiting plate 32 is hinged to the fixed limiting plate 31; when the bent portion 212 is in the first state, the upper end of the fixed limiting plate 31 abuts against the bent portion 212, and the lower end of the movable limiting plate 32 abuts against the base 1. In the embodiment, when the ship is not in collision, the bent portion 212 is in the first state, when the bent portion 212 is in the first state, the upper end of the fixed limiting plate 31 abuts against the bent portion 212, the lower end of the movable limiting plate 32 abuts against the base 1 to limit the outward swinging of the bent portion 212, and when a crew grasps the protection component 2, the safety of the crew is ensured; when the ship collides, the bending portion 212 drives the upright post 22 to swing inward, the bending portion 212 is in the second state in the process, and when the bending portion 212 is in the second state, the movable limiting plate 32 rotates around the fixed limiting plate 31 along with the swing of the bending portion 212.

Particularly, a first mounting hole is formed in the fixed limiting plate 31, a second mounting hole is formed in the movable limiting plate 32, and the fastener sequentially penetrates through the first mounting hole and the second mounting hole. In this embodiment, the fastening member is preferably a bolt and nut assembly, the first mounting hole is preferably a threaded hole, the second mounting hole is preferably a through hole, the bolt is sequentially inserted through the threaded hole and the through hole, and the nut is screwed on one end of the bolt far away from the bolt head. The bolt and nut assemblies are used for connection, the structure is simple, the connection is reliable, the disassembly and the assembly are convenient, the stable connection between the fixed limiting plate 31 and the movable limiting plate 32 can be realized, and the stability of the movable limiting plate 32 in the rotating process is ensured; secondly, this kind of arrangement can also avoid protecting component 2 to swing towards other directions, restricts protecting component 2 and only swings towards the outside direction of boats and ships. It should be noted that when the nut is screwed, a certain gap needs to be left between the fixed limiting plate 31 and the movable limiting plate 32 to ensure that the movable limiting plate 32 can rotate around the fixed limiting plate 31.

Further, in order to limit the swing angle of the protection component 2 towards the inner side and avoid the situation that the equipment on the ship is damaged due to the fact that the swing angle of the protection component 2 towards the inner side is too large, the marine guardrail further comprises an inner side limiting plate 4, the inner side limiting plate 4 is arranged on the inner side of the connecting piece 21, and the inner side limiting plate 4 is configured to limit the swing angle of the protection component 2. When a collision occurs in a ship, the connecting piece 21 swings towards the inner side under the action of impact force, but the swinging angle is too large, so that the upright post 22 collides with equipment on a ship walkway, and the equipment is damaged if the impact force is too large. Therefore, in the present embodiment, the inner side limiting plate 4 is disposed on the inner side of the connecting member 21 to limit the angle of the fender assembly 2 swinging to the inner side, so as to prevent the fender assembly 2 from swinging to the inner side by an excessive angle to cause damage to equipment on the ship.

Further, referring to fig. 2, the specific structure of the inside position-limiting plate 4 is described in detail, as shown in fig. 2, the inside position-limiting plate 4 includes a first side 41 and a second side 42 arranged at an included angle, one of the fixing portion 211 and the bending portion 212 is connected to the first side 41, and when the other of the fixing portion 211 and the bending portion 212 abuts against the second side 42, the bending portion 212 is at the limit bending position. In the present embodiment, the extension line of the first side 41 and the second side 42 form a limiting notch, and the limiting notch has an angle equal to the angle of the bending portion 212 swinging inward. When the bending portion is connected to the first side 41 and the fixing portion 211 abuts against the second side, the bending portion 212 reaches the limit bending position; alternatively, when the fixing portion 211 is connected to the first side 41 and the bending portion 212 abuts against the second side 42, the bending portion 212 reaches the limit bending position. The two modes can limit the inward swinging angle of the protection component 2, so as to prevent equipment on the ship from being damaged due to the fact that the inward swinging angle of the protection component 2 is too large.

Further, the outer periphery of the pillar 22 is provided with a buffer member. When boats and ships bump, the bolster has stronger cushioning effect, prevents that great impact force from causing this marine guardrail harm, has avoided because the consumption of manpower and materials that the marine guardrail damage caused to and time limit for a project delay and economic loss that the marine guardrail maintenance caused.

Specifically, the buffer members are a plurality of buffer blocks provided outside the column 22, and the plurality of buffer blocks are provided at intervals in the axial direction of the column 22. Preferably, the buffer block is made of an elastic material, and the elastic material has good buffer force and restoring force. In addition, the buffer block is bonded on the upright column 22, the arrangement mode is firm in connection and not easy to fall off, and when the buffer block is damaged, the buffer block can be detached from the upright column 22 and replaced by a new buffer block, so that the buffer block is convenient to detach and replace, and the maintenance cost is saved. Meanwhile, certain gaps need to be reserved between the buffer blocks, and therefore crews can conveniently grab and hold the upright posts 22.

Of course, in other embodiments, the buffer member may also be a rubber sleeve sleeved on the periphery of the pillar 22, and the above-mentioned effects can also be achieved.

Fig. 3 is a schematic view illustrating a working process of the guardrail for a ship according to the embodiment, and as shown in fig. 3, the working principle of the guardrail for a ship according to the embodiment is as follows:
