[0030] In addition, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0031] See also Figure 1The present embodiment provides a portable side working ladder for an offshore oil drilling platform, comprising a ladder frame body 1, a supporting leg assembly 2 and a locking assembly 3. The ladder frame body 1 extends straightly from a ladder head handrail end 101 to a ladder tail support end 102. The head end of the supporting leg assembly 2 is fixed to the ladder tail support end 102 of the ladder frame body 1. The tail end of the supporting leg assembly 2 is against the outer wall plate of the offshore oil drilling platform, and the lateral distance between the head and the tail of the supporting leg assembly 2 is 145mm-155mm. The locking assembly 3 is fixed to the ladder head handrail end 101 of the ladder frame body 1, and the locking assembly 3 is detachably connected to the water retaining flat iron on the side of the offshore oil drilling platform.

[0032] The portable side working ladder of the offshore oil drilling platform of this embodiment can be moved to the side of the offshore oil drilling platform as a whole when in use, and can be detachably connected to the water retaining flat iron at a suitable position through the locking assembly 3, thereby assisting the operator to complete related work. Since the working ladder can freely change the installation position and can be installed through the water retaining flat iron on the offshore oil drilling platform, it is simple and convenient, and the operator no longer needs to take more additional steps to access the designated working position, thereby reducing the difficulty of operation and safety risks.

[0033] At the same time, after the end of the supporting leg assembly 2 of the portable side working ladder of the offshore oil drilling platform of this embodiment abuts against the outer wall plate of the offshore oil drilling platform, the lateral distance between the head and the end of the supporting leg assembly 2 is 145mm-155mm, thereby ensuring that when the operator climbs the working ladder, the center position of the sole of the foot can be placed on the pedal structure of the ladder frame body 1, thereby improving the climbing comfort and ensuring the safety of the operation.

[0034] Preferably, see Figure 1 and Figure 2 The ladder frame body 1 includes a support rod 103 and a cross rod 104. The two support rods 103 are arranged in parallel and spaced apart, and are bent at the head end and extend in the opposite direction to form an arc-shaped handrail 105. A plurality of cross rods 104 are arranged in parallel and spaced apart in the space between the two support rods 103, and each cross rod 104 is arranged perpendicular to the support rod 103. It should be noted that the cross rod 104 is the pedal structure on the ladder frame body 1; and the handrail is designed to be arc-shaped, so that the operator can grasp the handrail more conveniently during the climbing process.

[0035] Preferably, see Figure 1 The support foot assembly 2 includes a support foot rod 201, the length of the support foot rod 201 is 145mm-155mm, the two support foot rods 201 are vertically arranged on the two support rods 103, and the ends of the two support foot rods 201 are vertically abutted against the outer wall plate of the offshore oil drilling platform.

[0036] Preferably, in this embodiment, the length of the support rod 201 is 150 mm.

[0037] Preferably, see Figure 1 The support foot assembly 2 also includes an elastic protective pad 202, which is sleeved on the end of the support foot rod 201 and abuts against the outer hull plate of the offshore oil drilling platform. The provision of the elastic protective pad 202 can effectively prevent the work ladder from damaging the paint on the outer hull plate of the offshore oil drilling platform.

[0038] Preferably, the elastic protection pad 202 is a rubber pad.

[0039] Preferably, see Figure 1 and Figure 3 The locking assembly 3 includes a slot block 301 and a locking screw 302. The two slot blocks 301 are respectively fixed on the two support rods 103, and the two locking screws 302 are respectively screwed on the two arc-shaped handrails 105. A snap-in groove 303 for snapping with the water-retaining flat iron is provided between each locking screw 302 and an opposite slot block 301.

[0040] When the locking assembly 3 is connected to the water retaining flat iron, the slot block 301 is clamped on a water retaining flat iron of the offshore oil drilling platform through the clamping slot 303, and then the locking screw 302 is tightened until it is pressure-contacted with the water retaining flat iron to complete the installation of the work ladder on the offshore oil drilling platform.

[0041] It should be noted that by providing the slot block 301 on the support rod 103 and the locking screw 302 on the arcuate handrail 105, the arcuate handrail 105 is effectively fixed, the connection strength of the arcuate handrail 105 itself is enhanced, and the safety of the work ladder is improved.

[0042] Preferably, see Figure 3 The locking screw 302 is a butterfly screw. The butterfly screw, relying on its own structural characteristics, enables the operator to more conveniently lock the work ladder on the water retaining flat iron on the side of the offshore oil drilling platform.

[0043] It was found during actual use that the portable side working ladder of the offshore oil drilling platform of this embodiment not only reduces the difficulty and risk of pile driving operations during the towing and pile pulling operations of the auxiliary platform, but also can save 3 hours of operation time when dismantling high and low pressure pipelines with three pile shoes.

[0044] In summary, the portable side working ladder of the offshore oil drilling platform of this embodiment has a firm structure, is easy to carry, is convenient to use, has obvious economic value, and is easy to promote and use.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
