This auxiliary device can be detachably connected to the ladder, and the protective body and the ladder form a double locking connection through the locking piece and the card interface on the U-shaped clamping part to ensure the safety of the entire auxiliary device, and the protective part provides auxiliary support for personnel standing on the ladder, so that the personnel can free their hands and improve work efficiency.
[0006] The inner side of the closed end of the U-shaped clamping part contacts the vertical rod of the ladder, and the open end of the U-shaped clamping part extends out of the vertical rod of the ladder and is connected via a locking piece. The U-shaped clamping part and the locking piece enclose an annular space in which the vertical rod of the ladder is sleeved, and the vertical rod is supported front and back by the inner side of the closed end of the U-shaped clamping part and the locking piece, thereby increasing the force points of the entire protective body and the ladder, thereby further improving the safety of the device when in use.
[0007] The locking member comprises a bolt and a nut. Through holes are provided on the side walls on both sides of the opening end of the U-shaped clamping portion. The bolts pass through the through holes in sequence and are matched with the nuts for connection.
[0008] The protection part is an open frame structure, the opening of the frame structure faces the straight ladder, and there are two U-shaped clamping parts, which are symmetrically arranged at both ends of the opening of the frame structure.
[0009] The opening direction of the U-shaped clamping part is opposite to the opening direction of the frame structure, and one side of the U-shaped clamping part is integrally formed with the frame structure. The U-shaped clamping part and the frame structure of the protective part are integrally formed, which can reduce the processing difficulty of the entire device. At the same time, the overall strength of the integrated processed part is higher than that of the welded part.

[0019] In order to enable those skilled in the art to better understand the technical solution in the utility model, the technical solution in the utility model is clearly and completely described below in conjunction with the accompanying drawings. Other embodiments obtained by those skilled in the art without making any creative work should all fall within the protection scope of the utility model.
[0020] like Figure 1-Figure 5 As shown, the utility model provides an auxiliary device for climbing up a marine engineering ladder, comprising a protective body 2 detachably connected to the ladder 1, the protective body 2 forming a protective portion 201 for surrounding the outside of the staff, the protective portion 201 being an open frame structure, the opening of the frame structure facing the ladder 1, preferably, the frame structure is a circular frame structure, the size L at the opening is smaller than the circular diameter D of the frame structure, U-shaped clamping portions 202 are fixed at both ends of the opening of the protective portion 201, the open ends of the U-shaped clamping portions 202 are fitted and inserted into the vertical rods 101 on both sides of the ladder 1, and the side walls of the U-shaped clamping portions 202 are provided with a card interface 5 that cooperates with the cross rod 102 of the ladder 1, and the U-shaped clamping portions 202 are provided with a locking member 4 for limiting the vertical rods 101 of the ladder 1 from being separated from the open ends of the U-shaped clamping portions 202.
[0021] The auxiliary device forms a double locking connection with the vertical ladder 1 through the locking piece 4 and the card interface 5 on the U-shaped clamping part 202, thereby ensuring the safety of the entire auxiliary device. At the same time, the frame structure of the protection part 201 provides an auxiliary support point for personnel to stand on the vertical ladder 1, so that personnel can free their hands and improve work efficiency.
[0022] To further improve the effective support of the locking member 4, the inner side of the closed end of the U-shaped clamping portion 202 contacts the vertical rod 101 of the ladder 1, and the open end of the U-shaped clamping portion 202 extends out of the vertical rod 101 of the ladder 1 and is connected via the locking member 4. Figure 5 As shown, the U-shaped clamping portion 202 and the locking member 4 form an annular space for mounting the vertical rod 101 of the straight ladder 1, and the cross bar 102 at the card interface 5 is used as a fulcrum. The vertical rod 101 is supported front and back through the inner side of the closed end of the U-shaped clamping portion 202 and the locking member 4, thereby increasing the force points of the entire protective body 2 and the straight ladder 1, thereby improving the supporting effect of the entire protective device.
[0023] Further preferably, the locking member 4 includes a bolt 401 and a nut 402 , and through holes are provided on the side walls on both sides of the open end of the U-shaped clamping portion 202 , and the bolt 401 passes through the through holes in sequence and is matched with the nut 402 for connection.
[0024] In the present invention, the opening direction of the U-shaped clamping portion 202 is opposite to the opening direction of the frame structure, and one side of the U-shaped clamping portion 202 is integrally formed with the frame structure. Figure 3As shown, the entire device can be formed by bending a 60*5mm flat steel multiple times. The processed protective part 201 has a certain bending elasticity. There are no welds in the entire processing process, the processing difficulty is low, and the structural integrity is good, thereby ensuring the strength of the entire device; in addition, the device has smooth transitions at various locations, which avoids scratching personnel and can also improve stress concentration.
[0025] Further preferably, the cross-section of the crossbar 102 of the vertical ladder 1 is a rectangle, and the card interface 5 is provided with an angular structure matching the rectangle. Figure 4 As shown, the vertical diagonal of the rectangular cross bar 102 is parallel to the axis of the vertical bar 101, and the angular structure of the card interface 5 includes a right angle at the top and obtuse angles on both sides. One of the two obtuse angles is set in parallel, and the distance between the parallel sides is adapted to the horizontal diagonal size of the rectangular cross bar 102. The design of the above-mentioned rectangular cross bar 102 can not only improve the fit between it and the card interface 5, but also improve the friction of the cross bar 102 as a pedal surface to prevent people from stepping on empty space.
[0026] In order to improve the comfort of the protective part 201, a protective pad 3 is provided on the outer side of the protective part 201, and the protective pad 3 is a flexible protective pad. In this embodiment, the protective pad 3 can be rubber or sponge, and the protective pad 3 covers at least half of the length of the protective part 201. When a person leans on it, it provides a cushioning effect for the person, which can reduce the wear on the clothes or limbs caused by the friction between the person and the protective part 201.
