Description

Technical Field

[0001] The utility model relates to the technical field of climbing tools, and particularly relates to a rope ladder. Background Art

[0002] Due to the advantages of convenient use and storage, low cost, etc., the rope ladder is widely used in daily inspections and maintenance operations. Except that the cross braces of the marine rope ladder standard specifications require wooden boards, the common cross braces of the rope ladders on the market are still mainly round wooden sticks.

[0003] At present, for the common rope ladder with round wooden sticks as cross braces, when it is used completely suspended, the middle part of the sole can rest on the round cross braces. However, when it is used on a slope, since the rope ladder is close to the slope, the cross braces on the rope ladder are in contact with the slope or have a very small spacing, resulting in that only the toes of the user can step on the cross braces. This not only makes it difficult for the user to step firmly, increases the tension of the user, poses a safety hazard, but also greatly affects the ladder climbing speed. Content of the Utility Model

[0004] The purpose of the utility model is to develop a rope ladder that keeps a spacing between the cross braces and the slope when used on a slope.

[0030] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0031] Embodiment 1

[0032] As Figures 1 to 3 shown, this embodiment discloses a rope ladder, which includes a plurality of cylindrical cross braces 1 arranged parallel to each other at equal intervals, and a guy rope 2 is connected between the ends of adjacent two cross braces 1.

[0033] Two detachable support mechanisms 3 are provided on the cross brace 1, and the two support mechanisms 3 are arranged at both ends of the cross brace 1. The support mechanism 3 contacts the slope surface, so that there is enough space for people's footsteps to step on between the cross brace 1 and the slope surface.

[0034] The support mechanism 3 includes two support units with the same structure and symmetrically arranged. The support unit includes an arc-shaped support plate 31. The inner diameter of the inner arc surface of the support plate 31 is adapted to the outer diameter of the cross brace 1. Two support rods 32 are provided on the outer wall of the support plate 31. The support rods 32 are arranged radially along the inner arc surface of the support plate 31, and the two support rods 32 are spaced at a central angle of 90 degrees, and the two support rods 32 are spaced at a central angle of 45 degrees from the end surface of the side support plate 31.

[0035] In the support mechanism 3, the support plates 31 of the two support units are clamped. After clamping, the two support plates 31 enclose a cylinder with an inner diameter adapted to the outer diameter of the cross brace 1. Since the support rod 32 is spaced from the end of the support plate 31 where it is located by a central angle of 45 degrees, after the two support plates 31 are clamped to form a cylinder, the four support rods 32 are arranged at intervals of 90 degrees of the central angle on the outer wall of the cylinder circumference.

[0036] One end of the support plate 31 in the circumferential direction is provided with a clamping block 36, and the other end of the support plate 31 in the circumferential direction is provided with a clamping groove 35 corresponding to the position of the clamping block 36. When the support plates 31 of the two support units are clamped, the clamping blocks 36 and the clamping grooves 35 at both ends of one support plate 31 are respectively clamped with the clamping grooves 35 and the clamping blocks 36 at both ends of the other support plate 31.

[0037] After the two support plates 31 of the two support units are clamped, generally the two support plates 31 will not separate. In order to stably connect the two support plates 31 to improve safety, a connecting component for connecting the two support units is further provided in the support mechanism 3.

[0038] The connecting component includes a connecting plate 33 provided at one end in the axial direction of the support plate 31. The connecting plate 33 is an arc-shaped plate body having the same shape as the support plate 31. Both ends of the connecting plate 33 are provided with support plates 34. The support plates 34 extend to the outside of the connecting plate 33 and are arranged along the radial direction of the connecting plate 33. The support plates 34 are provided with screw holes. After the support plates 31 of the two support units are clamped, the support plates 34 of the two connecting plates 33 are in contact. By connecting bolts to the screw holes of the two support plates 34, bolt connection of the two connecting plates 33 is realized.

[0039] When the rope ladder is used on the slope surface, the support mechanism 3 can be installed on the cross brace 1. After the support plates 31 of the two support units of the support mechanism 3 are clamped, the two connecting plates 33 are bolt-connected. The two support rods 32 of the support mechanism 3 abut against the slope surface, so that there is enough space for people to step on between the cross brace 1 and the slope surface. When the rope ladder is not used on the slope surface, the support mechanism 3 can be removed.

[0040] Embodiment 2

[0041] As Figure 4 and Figure 5 shown, the difference between this embodiment and Embodiment 1 is: the structure of the connecting component is different.

[0042] In this embodiment, the connecting component includes a connecting block 38 provided at one end of the support plate 31. The inner wall of the connecting block 38 is in an arc shape adapted to the inner arc surface of the support plate 31. A layer of anti-slip layer is provided on the inner wall of the connecting block 38. The anti-slip layer enhances the friction between the inner wall of the connecting block 38 and the cross brace 1. The anti-slip layer can be a rubber layer. The outer wall of the connecting block 38 is a conical surface and is provided with threads on the outer wall. After the two support plates 31 are snap-fitted to form a cylinder, the two connecting blocks 38 also enclose to form a cylinder with a cylindrical inner wall and a frustum-shaped outer wall. There is a certain gap between the ends of the two connecting blocks 38. The larger-diameter end of the outer diameter of this cylinder is connected to the support plate 31. The threads on the outer wall of the connecting block 38 form a tapered thread on the outer wall of this cylinder. The connecting component further includes a tapered nut 37, and the tapered nut 37 cooperates with this tapered thread. When the support mechanism 3 is not in use, the tapered nut 37 is sleeved on the cross brace 1. When the support mechanism 3 is in use, after the support plates 31 of the two support units are snap-fitted, the tapered nut 37 is screwed onto the tapered thread.

[0043] In this embodiment, as the tapered nut 37 is threadedly connected to the connecting block 38, the two connecting blocks 38 gradually approach and tightly adhere to the cross brace 1. The anti-slip layer on the inner wall of the connecting block 38 can fix the connecting block 38 on the cross brace 1, realizing the fixation of the support mechanism 3.

[0044] The above embodiments are only the preferred embodiments of the present invention and do not limit the technical solutions of the present invention. Any technical solution that can be achieved on the basis of the above embodiments without creative labor shall be regarded as falling within the scope of the patent rights of the present invention.
