Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to an inclined ladder. Background Art

[0002] The machinery space of a ship refers to the place and passage where the main engine, auxiliary engine, boiler, inert gas generator and other equipment are installed. When the ship is floating or the heel is not greater than 5°, it can be drained through at least two bilge water suction ports. One of the above suction ports should be a branch suction port, and the other should be a direct bilge pump suction port. After an accident, the accumulated water in the machinery space should be able to be drained regardless of whether the ship is floating or tilted. The existing inclined ladder in the machinery space on the ship can ensure the use of the passage, but when in use, the inclined ladder may become slippery due to steam, etc., causing the operator to slip and fall. At the same time, dust and debris may drift into the equipment along the inclined ladder, affecting the normal use of the equipment. Summary of the invention

[0003] The object of the present invention is to provide an inclined ladder which can improve the safety of use and reduce the impact of dust and debris on mechanical premises.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] Inclined ladder, installed in machinery space, including:

[0006] A ladder frame, the ladder frame having multiple layers of pedals arranged in sequence, the upper end surfaces of the multiple pedals are all provided with anti-slip parts, and the upper end of the ladder frame is connected to the mechanical space;

[0007] A dustproof plate is arranged on the ladder frame opposite to the pedal, and the dustproof plate is arranged on a side close to the machinery space.

[0008] As a further technical solution, along the length direction of the ladder frame, the dustproof plate and the ladder frame are arranged parallel to each other.

[0009] As a further technical solution, the dustproof plate is recessed in a direction away from the pedal.

[0010] As a further technical solution, a top pedal among the multiple layers of pedals extends toward the direction close to the mechanical location and covers an end of the dustproof plate close to the top pedal.

[0011] As a further technical solution, at least one reinforcing plate is provided on the lower end surface of the top pedal, and the reinforcing plate is provided on a side close to the dustproof plate.

[0012] As a further technical solution, the inclined ladder also includes a connecting assembly, and the dustproof plate is detachably connected to the ladder frame through the connecting assembly.

[0013] As a further technical solution, a plurality of groups of the connecting components are arranged at intervals on both sides of the ladder frame, each of the connecting components comprises a connecting screw, a connecting nut, a connecting plate and two connecting washers, and the dustproof plate is provided with corresponding mounting holes;

[0014] The first end of the connecting screw passes through the mounting hole and the connecting hole on the connecting plate in sequence, the connecting nut is screwed to the first end of the connecting screw, and the two connecting washers are both sleeved on the connecting screw and respectively abut against two end surfaces of the connecting plate and the dustproof plate that are away from each other.

[0015] As a further technical solution, the anti-slip member is integrally formed and protrudes from the upper end surface corresponding to the pedal;

[0016] Alternatively, the anti-slip member can be detachably arranged on the upper end surface corresponding to the pedal.

[0017] As a further technical solution, the lower end surfaces of the multiple layers of the pedals are provided with reinforcements, the reinforcements extend along the width direction of the ladder frame, and each pedal is provided with at least one reinforcement.

[0018] As a further technical solution, the inclined ladder includes two handrail assemblies, and the two handrail assemblies are arranged at intervals along the width direction of the ladder frame on a side of the ladder frame away from the dustproof plate.

[0019] Compared with the prior art, the inclined ladder provided by the present invention has the following technical advantages:

[0020] Since the upper end surface of each pedal is provided with an anti-skid piece, the anti-skid piece can increase the surface friction of the upper end surface of the pedal, thereby reducing the impact of the slippery situation caused by steam on the operator, preventing the operator from slipping and falling on the inclined ladder, thereby improving the safety of the operation. Since a dustproof plate is provided on the side of the ladder frame close to the mechanical space corresponding to each pedal to avoid interference with multiple pedals, while ensuring the use effect of the inclined ladder, the dustproof plate can prevent dust and debris from drifting into the mechanical space along the inclined ladder, thereby reducing the impact of dust and debris on the mechanical space and ensuring the use effect of the mechanical space.

[0033] Before any embodiments of the application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above drawings.

[0034] In this application, the terms "comprises", "includes", "has" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0035] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects before and after are in an "and / or" relationship.

[0036] In the present application, the terms "connect", "combine", "couple", and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, direct connection refers to two parts or components being connected together without the need for an intermediate piece, and indirect connection refers to two parts or components being connected to at least one intermediate piece respectively, and the two parts or components being connected via the intermediate piece. In addition, "connect" and "couple" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0037] In the present application, it will be understood by those of ordinary skill in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerances caused by manufacturing, assembly, and use associated with a specific value, and the like. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0038] In this application, it will be understood by those skilled in the art that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0039] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, the bottom can include directly below, lower left, lower right, lower front, and lower back, etc.

[0040] Combination Figures 1 to 6 As shown, the inclined ladder provided in this embodiment is arranged in the mechanical place, so as to ensure the use of the passage, improve the safety of use, and reduce the influence of dust and debris on the mechanical place. Specifically, the inclined ladder includes a ladder frame 100 and a dustproof plate 200: the ladder frame 100 has multiple layers of pedals 110 arranged in sequence, and the upper end surfaces of the multiple pedals 110 are all provided with anti-slip parts 120, and the upper end of the ladder frame 100 is connected to the mechanical place; the dustproof plate 200 is arranged on the ladder frame 100 opposite to the pedals 110, and the dustproof plate 200 is arranged on the side close to the mechanical place.

[0041] Since the upper end surface of each pedal 110 is provided with an anti-skid member 120, the anti-skid member 120 can increase the surface friction of the upper end surface of the pedal 110, thereby reducing the impact of the slippery situation caused by steam on the operator, preventing the operator from slipping and falling on the inclined ladder, thereby improving the safety of the operation. Since the side of the ladder frame 100 close to the mechanical space is provided with a dustproof plate 200 corresponding to each pedal 110, interference with multiple pedals 110 is avoided, and the use effect of the inclined ladder is ensured. At the same time, the dustproof plate 200 can prevent dust and debris from drifting into the mechanical space along the inclined ladder, thereby reducing the impact of dust and debris on the mechanical space and ensuring the use effect of the mechanical space.

[0042] In addition, in this embodiment, the ladder frame 100 is composed of two relatively spaced channel steels that cooperate with each other, and both ends of each step 110 in the length direction are fixed to the corresponding channel steel, thereby improving the strength of the inclined ladder and further improving the safety of use. In other embodiments, the ladder frame 100 is composed of two relatively spaced mounting plates that cooperate with each other.

[0043] The material of the dustproof plate 200 is not specifically limited in this embodiment, and can be set to a rubber plate, a stainless steel plate or an aluminum plate according to actual needs, as long as it can achieve the technical effect of preventing dust and debris from drifting into the machinery space along the inclined ladder.

[0044] Preferably, along the length direction of the ladder frame 100, the dust-proof plate 200 is arranged parallel to the ladder frame 100.

[0045] Specifically combined with Figure 1 As shown, with such an arrangement, while ensuring the dust-proof effect of the inclined ladder, the volume of the inclined ladder can be minimized as much as possible. During use, the probability of interference between the inclined ladder and the machinery space can be reduced, and the structure of the inclined ladder can be made simpler. Further, as Figure 3 shown, the dust-proof plate 200 is recessed in a direction away from the pedal 110. That is, along the length direction of the channel steel, the cross-sectional shape of the dust-proof plate 200 is a "U" shape, so as to form an avoidance area between the bottom wall of the dust-proof plate 200 and each pedal 110; there are differences in the foot sizes of operators with different body types, and since there is an avoidance area between the dust-proof plate 200 and each pedal 110, while ensuring the dust-proof effect of the dust-proof plate 200, each pedal 110 is suitable for being stepped on by feet of different sizes, thereby improving the applicability and safety of the inclined ladder.

[0046] Preferably, the top pedal 111 of the multi-layer pedal 110 extends towards the machinery space and covers one end of the dust-proof plate 200 close to the top pedal 111.

[0047] Specifically combined with Figure 1 As shown, with such an arrangement, the top pedal 111 can prevent dust, sundries, etc. from drifting into the machinery space from above the inclined ladder, so as to further improve the dust-proof effect of the inclined ladder.

[0048] Preferably, at least one reinforcing plate 112 is arranged on the lower end surface of the top pedal 111, and the reinforcing plate 112 is arranged on the side close to the dust-proof plate 200. Since the width of the top pedal 111 is relatively large, the reinforcing plate 112 can improve the strength of the side of the top pedal 111 close to the dust-proof plate 200, and at the same time improve the flatness of the top pedal 111 to prevent the top pedal 111 from deforming. In this embodiment, the cross-sectional shape of the reinforcing plate 112 is not limited.

[0049] Preferably, the inclined ladder further includes a connection assembly 300, and the dust-proof plate 200 is detachably connected to the ladder frame 100 through the connection assembly 300. As the use time of the inclined ladder increases, the dust and sundries accumulated on the dust-proof plate 200 gradually increase, and there may be a situation where a small amount of the accumulated dust and sundries drifts into the machinery space; and since the dust-proof plate 200 is detachably connected to the ladder frame 100, when the dust and sundries on the dust-proof plate 200 accumulate too much, the dust-proof plate 200 can be removed from the ladder frame 100 for cleaning and replacement, so as to further ensure the use effect of the machinery space.

[0050] In some other embodiments, the dust-proof plate 200 can also be directly fixedly connected to the ladder frame 100 by connection methods such as welding and bonding.

[0051] Preferably, multiple groups of connecting components 300 are arranged at intervals on both sides of the ladder frame 100, each connecting component 300 includes a connecting screw 310, a connecting nut 320, a connecting plate 330 and two connecting washers 340, and a corresponding mounting hole is arranged on the dustproof plate 200; the first end of the connecting screw 310 passes through the mounting hole and the connecting hole on the connecting plate 330 in turn, and the connecting nut 320 is screwed to the first end of the connecting screw 310; the dustproof plate 200 is connected to the ladder frame 100 by cooperating with the connecting screw 310 and the connecting nut 320, while ensuring the connection strength and connection stability of the dustproof plate 200, it is convenient to disassemble, clean or replace the dustproof plate 200, and since the dustproof plate 200 is connected to the corresponding channel steel through the connecting plate 330, it is possible to avoid opening a hole in the channel steel, thereby ensuring the self-strength of the ladder frame 100 and improving the safety of use. The two connection washers 340 are both sleeved on the connection screw 310 and respectively abut against the end faces of the connection plate 330 and the dustproof plate 200 that are away from each other. By cooperating with the connection plate 330 and the dustproof plate 200, it is possible to avoid the connection screw 310 from being separated from the connection plate 330 and the dustproof plate 200 under the action of external force, so as to further improve the connection strength. In addition, in this embodiment, the connection hole is set as a long hole, and the extension direction of the long hole is perpendicular to the length direction of the channel steel. In this way, by adjusting the position of the connection screw 310 in the corresponding long hole, the dustproof plate 200 can be locally fine-tuned to ensure the flatness of the dustproof plate 200, thereby reducing the accumulation of dust and debris on the dustproof plate 200. There is no limit on the number of connection components 300, and the technical purpose of cooperating with multiple groups of connection components 300 to detachably connect the dustproof plate 200 to the ladder frame 100 can be achieved. In this embodiment, five groups of connection components 300 are arranged on the channel steel on the same side, and the five groups of connection components 300 are evenly spaced along the length direction of the channel steel.

[0052] Preferably, the anti-slip part 120 is integrally formed and protrudes from the upper end surface of the corresponding pedal 110; in this state, the anti-slip part 120 can be set as an anti-slip convex point or an anti-slip convex rail, and is integrally formed with the corresponding pedal 110; taking the anti-slip convex rail as an example, a plurality of anti-slip convex rails are provided, and the plurality of anti-slip convex rails are spaced along the length direction or the width direction of the pedal 110, thereby ensuring the anti-slip effect while reducing the difficulty of production.

[0053] The anti-skid member 120 is detachably provided on the upper end surface of the corresponding pedal 110. In this state, the anti-skid member 120 is provided as an anti-skid plate with anti-skid patterns or anti-skid protrusions, and the anti-skid plate is detachably provided on the upper end surface of the corresponding pedal 110. As the inclined ladder is used for a longer time, the anti-skid patterns or anti-skid protrusions on the anti-skid plate will wear out. When the anti-skid effect of the anti-skid plate is weakened, a new anti-skid plate can be directly replaced to further ensure the anti-skid effect. The connection method of the anti-skid plate detachably connected to the corresponding pedal 110 can be selected according to actual needs, such as bonding, clamping, and connection with threaded connectors, which is not specifically limited in this embodiment.

[0054] Preferably, the lower end surfaces of the multi-layered pedals 110 are each provided with a reinforcement 130 , the reinforcement 130 extends along the width direction of the ladder frame 100 , and each pedal 110 is provided with at least one reinforcement 130 .

[0055] The cross-sectional shape and the actual number of reinforcement members 130 are not specifically limited. Figure 5 As shown, two reinforcement members 130 are arranged at intervals along the width direction of the pedal 110, and the two reinforcement members 130 are respectively arranged close to the side walls in the width direction of the pedal 110; the reinforcement members 130 can improve the strength and flatness of the corresponding pedal 110, reduce the probability of deformation of the pedal 110, thereby improving the safety of using the inclined ladder; and because the reinforcement members 130 are arranged on the lower end surface of the corresponding pedal 110, it can avoid tripping of the operator.

[0056] Preferably, the inclined ladder comprises two handrail assemblies 400 , and the two handrail assemblies 400 are arranged at intervals along the width direction of the ladder frame 100 on a side of the ladder frame 100 away from the dustproof plate 200 .

[0057] Specific combination Figure 1 , Figure 2 and Figure 6 As shown, the two handrail assemblies 400 can further improve the safety of the inclined ladder and prevent the operator from falling off the inclined ladder from one side. In this embodiment, each group of handrail assemblies 400 includes a protective rod 410, a plurality of reinforcing rods 420 and a plurality of auxiliary plates 430; the two ends of the protective rod 410 are respectively fixedly arranged at the two ends of the corresponding channel steel, and the middle part is bent in the direction away from the corresponding channel steel, so that the bent protective rod 410 cooperates with the corresponding channel steel to form a guardrail; the plurality of reinforcing rods 420 are evenly spaced along the length direction of the corresponding channel steel, and the plurality of reinforcing rods 420 are vertically arranged with the corresponding channel steel, the first end of each reinforcing rod 420 is fixedly connected to the corresponding protective rod 410, and the second end is fixedly connected to the channel steel through the corresponding auxiliary plate 430, so as to improve the connection strength of the protective rod 410, thereby improving the protective effect of the handrail assembly 400.

[0058] In some other embodiments, the handrail assembly 400 can also be directly set as a protective plate, the length of the protective plate is set corresponding to the channel steel, the protective plate is fixedly connected to the corresponding channel steel, and the protective plate is vertically set to the corresponding channel steel.
