Description

Technical Field

[0001] The present invention relates to the field of handrail structures, and more particularly to a connecting handrail device. Background Art

[0002] In some practical scenarios, a platform is connected to the next-level plane by a sloping ladder or the like so that personnel can descend from the platform to the next-level plane. For example, on a helicopter hovering or mooring platform on a ship, it is generally connected to the deck by a sloping ladder. A fence is also arranged around the platform. When the helicopter lands, the fence must be laid down. In the prior art, people have to manually remove the fence, which increases the insecurity.

[0003] More importantly, there is often a section between the fence and the sloping ladder where there are no handrails on both sides. When personnel descend the sloping ladder to the next-level platform, i.e., the deck, it is even more insecure. For the above application scenarios, there is no technical solution in the prior art to solve this problem.

[0004] Therefore, there is an urgent need for a connecting handrail device, which helps to solve the technical problem in the prior art that there is a lack of a handrail attached to the sloping ladder to ensure that there is a handrail at the connection with the variable fence, resulting in insecurity when personnel descend the sloping ladder. Summary of the Invention

[0005] In one embodiment, the present invention provides a connecting handrail device. By means of a first handrail arm and a second handrail arm, when the folding part, i.e., the fence and the sloping ladder, changes, a handrail can be connected therebetween, which helps to solve the technical problem in the prior art that there is a lack of a handrail attached to the sloping ladder to ensure that there is a handrail at the connection with the variable fence, resulting in insecurity when personnel descend the sloping ladder.

[0006] The connecting handrail device includes a folding part, a first handrail arm, a second handrail arm and a sloping ladder;

[0007] One end of the folding part is hinged to a base so that the folding part rotates along a first angle to realize folding down and lifting up;

[0008] One end of the first handrail arm is hinged to the folding part;

[0009] One end of the second handrail arm is hinged to the other end of the first handrail arm;

[0010] The sloping ladder is located below the folding part and extends downward along a predetermined slope within the rotation plane of the first angle. The sloping ladder has a handrail near the end close to the folding part. The other end of the second handrail arm is hinged to the handrail so that when the folding part is folded down, the first handrail arm and the second handrail arm are folded, and when the folding part is lifted up, the first handrail arm and the second handrail arm unfold to block the gap between the handrail and the folding part.

[0011] In one embodiment, the first handrail arm and the second handrail arm form a straight arm after being unfolded.

[0012] In one embodiment, the first handrail arm and the second handrail arm are located on the same outer side of the inclined ladder.

[0013] In one embodiment, the first handrail arm and the second handrail arm are of a circular tube structure. One end of the first handrail arm is radially hinged to one end of a connecting section along the radial direction of its length, and the other end of the connecting section is fixed on the folding component;

[0014] The circular tube structure is radially connected with a connecting pipe. Rotating shafts are arranged along the radial direction of the rotation direction of the first handrail arm on both sides of the inner circle of the connecting pipe, and one end of the connecting section is inserted through the rotating shaft to achieve rotation.

[0041] First of all, the scenario on which the present invention is based is that a base 10 is required, and a guardrail is arranged around the base 10. Before the guardrail is folded down, people can walk on the inclined ladder 4 and descend to the next lower platform. That is to say, the design requirement of the present invention is that when the guardrail is in the vertical state, a transitional handrail between the guardrail and the inclined ladder 4 is required. In addition, when a helicopter lands on the base 10, the guardrail is in the folded-down state. At this time, there is no need to remove the guardrail and the transitional handrail. In the prior art, it is necessary for people to remove the guardrail so that the helicopter can land on the base 10.

[0042] Figure 1 Schematic diagram of the first working state structure of a connecting handrail device in an embodiment of the present invention, Figure 2 Schematic diagram of the second working state structure of a connecting handrail device in another embodiment of the present invention. As Figure 1 and Figure 2 shown, in an embodiment, the present invention provides a connecting handrail device, and the connecting handrail device includes a folding member 1, a first supporting arm 2, a second supporting arm 3, and an inclined ladder 4;

[0043] One end of the folding member 1 is hinged to the base 10 so that the folding member 1 rotates along a first angle to realize folding down and lifting;

[0044] One end of the first supporting arm 2 is hinged to the folding component 1;

[0045] One end of the second supporting arm 3 is hinged to the other end of the first supporting arm 2;

[0046] The inclined ladder 4 is located below the folding component 1 and extends downward along a predetermined slope within the rotation plane of the first angle. One end of the inclined ladder 4 close to the folding component 1 is provided with a handrail 41. The other end of the second supporting arm 3 is hinged to the handrail 41. When the folding component 1 is folded down, the first supporting arm 2 and the second supporting arm 3 are folded. When the folding component 1 is lifted, the first supporting arm 2 and the second supporting arm 3 are unfolded to block the gap between the handrail 41 and the folding component 1.

[0047] In this embodiment, a specific structure of the connecting handrail device is provided. Taking a helicopter platform and the next-level platform as an example, when a helicopter or the like needs to be parked on the base 10, the folding component 1, that is, the guardrail. At this time, the first supporting arm 2 and the second supporting arm 3 are in a folded state. At this time, for helicopter landing and no one is walking, so the first supporting arm 2 and the second supporting arm 3 can be in a folded state. In the prior art, generally, the folding component 1, that is, the guardrail, will be manually removed at this time. However, the technical solution of the present invention does not require removing the guardrail. Generally, a motor or a hydraulic device is provided at the bottom of the folding component 1 to help it achieve two states of lifting or folding down. In Figure 2 a coordinate system of the X - Y axis is established, and the plane formed by the rotation of the first angle is also marked. The folding of the first supporting arm 2 and the second supporting arm 3 is also achieved in this plane. When the first supporting arm 2 and the second supporting arm 3 are unfolded, the interval between the folding component 1 and the handrail 41 can be blocked. At this time, when the folding component 1 is erected, people can walk on the inclined ladder 4. The handrail 41 is arranged on one side of the inclined ladder 4, has a certain height from the slope of the inclined ladder 4, and is connected to the inclined ladder 4 after being bent 90 degrees through an arc transition. In summary, the present invention helps to solve the technical problem in the prior art that there is a lack of a handrail attached to the inclined ladder to ensure the connection with the movable fence, resulting in unsafe walking of people down the inclined ladder.

[0048] It should be noted that the helicopter platform is only used to illustrate this embodiment and is not a specific limitation of this embodiment.

[0049] In one embodiment, the first supporting arm 2 and the second supporting arm 3 form a straight arm after being unfolded.

[0052] In this embodiment, a specific positional relationship among the first armrest 2, the second armrest 3, and the inclined ladder 4 is provided. Figure 3 The specific position where people walk is also marked. It can be seen that the folding component 1, the first armrest 2, and the second armrest 3 are all on one side of the inclined ladder 4, so there will be no interference phenomenon.
