[0025] By Figs. 1-2 It can be known that the safety net support frame for the ship gangway provided by the embodiments of the present application comprises a support 6, a support sleeve 2 vertically welded on the support 6, a support rod 1 sleeved inside the support sleeve 2, a pin shaft 3 for fixing and connecting the support sleeve 2 and the support rod 1, a split pin 7 and a net hanging ring 9 welded on the lower side of the support rod 1, and a plurality of connecting holes 8 are equidistantly arranged on the support end of the support rod 1. By arranging a plurality of connecting holes 8 on the support rod 1, the operator can flexibly select the position of the pin shaft 3 inserted into the connecting hole 8 according to the actual needs, so as to easily adjust the expansion length of the support rod 1, not only enabling the safety net to quickly adapt to gangways of different sizes, but also enabling a larger safety protection area to be formed by expansion, ensuring that every inch of space below the gangway can be effectively covered, greatly reducing the risk of accidental falling of personnel or materials; at the same time, a plurality of net hanging rings 9 are welded on the support rod 1, which are uniformly distributed to form a multi-point support structure, not only facilitating the quick mounting and fixing of the safety net, but also effectively dispersing the weight of the safety net and its load, avoiding the possible structural damage caused by excessive stress on a single point. This multi-point dispersion bearing method greatly improves the overall bearing capacity of the support frame, enabling it to safely support heavier loads, and even in the face of adverse weather or high-intensity use scenarios, it can remain stable and reliable.

[0026] The support base 6 is the support base of the whole support frame, and one end of the support base 6 is provided with a clamping groove. A layer of high-density rubber is laid in the clamping groove of the support base 6. The high-density rubber significantly increases the internal static friction force by virtue of its friction characteristics, so that the combination between the support base 6 and the vertical beams of the gangway is more compact and firm. Even in bad weather conditions or under a large load, the support base 6 can also remain stable and not shake. In actual use, the operator only needs to buckle the clamping groove of the support base 6 on the vertical beams on both sides of the gangway. Through the close cooperation between the clamping groove and the vertical beams and the assistance of the high-density rubber, a safe and reliable support system can be established.

[0027] The support sleeve 2 is vertically welded at a predetermined position of the support base 6. The support sleeve 2 is a hollow cylindrical structure, which provides the function of accommodating the support rod 1. At the same time, the inner wall of the support sleeve 2 is smooth, which maximally reduces the friction resistance of the support rod 1 during insertion and movement, so that the expansion length of the support rod 1 can be easily adjusted. It can be understood that the diameter of the support sleeve 2 is slightly larger than the diameter of the support rod 1, which not only ensures that the support rod 1 can move freely, but also avoids the shaking or instability phenomenon caused by too large gap, thereby ensuring the stability of the support frame.

[0028] It can be understood that the support sleeve 2 is fixedly welded to the support base 6 by low-temperature cold welding.

[0029] It can be understood that the support sleeve 2 is provided with a through hole for the pin shaft to penetrate.

[0030] The support rod 1 is sleeved in the support sleeve 2. The relative position of the support rod 1 in the support sleeve 2 can be adjusted according to actual needs, so as to accurately determine the required fixed position, and then the expansion length of the support rod 1 is adjusted. The support rod 1 is uniformly provided with connecting holes 8 at the support base end. These holes are used to cooperate with the pin shaft 3 to fix the support rod 1 and the support sleeve 2. Optionally, the connecting holes 8 are equidistantly arranged on the support rod 1.

[0031] The pin shaft 3 penetrates the through hole of the support sleeve 2 and the connecting hole 8 on the support rod 1, thereby effectively fixing the two components together. In order to ensure the stability of the connection between the two components under various complex working conditions, especially under the action of vibration, impact force or other external force, an open pin 7 is further arranged. The open pin 7 penetrates the reserved hole of the pin shaft 3, which prevents the pin shaft from accidentally falling off due to vibration or sudden external force impact caused by long-time operation, thereby enhancing the reliability of the connection.

[0032] The net hanging ring 9 is welded to the end of the support rod 1 away from the support base, which is used for hanging the safety net. Optionally, the net hanging ring 9 is designed as a circle, which has sufficient strength and opening width to ensure that the rope or special hook of the safety net can be easily and quickly penetrated and connected into the net hanging ring.

[0033] The plurality of net hanging rings 9 are equidistantly arranged to form a multi-point support structure, which not only facilitates the quick mounting and fixing of the safety net, but also effectively disperses the weight of the safety net and its load, avoiding the structural damage caused by excessive stress on a single point.

[0034] The net hanging ring 9 is forged from high-strength alloy steel or stainless steel, ensuring that the net hanging ring 9 can maintain its strength and toughness when subjected to the weight of the safety net itself and unexpected impacts and falling objects, thereby effectively avoiding the occurrence of safety hazards such as breakage or deformation.

[0035] The safety net support frame for the ship gangway of the utility model further comprises a bolt 5 and a hanging chain 4 connected to one end of the bolt 5 and the other end of the pin shaft 3.

[0036] One end of the hanging chain 4 is fixed to the support through the bolt 5, and the other end is fixed to the pin shaft, which can prevent the risk of accidental shedding of the pin shaft caused by various external adverse factors (such as vibration, impact, long-term load changes, or harsh environmental conditions, etc.), and through the double-stable way of the split pin 7 and the hanging chain 4, the risk of accidents caused by improper maintenance or accidental failure is reduced.

[0037] It can be known that the single set of device length provided by the utility model embodiment is 1100mm, so the gangway support rods on both sides can be extended to a safety distance of 2200mm.

[0038] As can be readily understood by those skilled in the art, the above description is only a preferred embodiment of the utility model, and is not intended to limit the utility model, and any modifications, equivalent replacements, and improvements made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
