DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example

[0032] Refer to the instruction manual Figure 1-Figure 11A climbing rope ladder with replaceable pedals, comprising a side rope 4 and steps, the steps are connected in series to the side rope 4, the upper and lower sides of the steps are respectively provided with an aluminum alloy clamp ring 5 and an embedded ring 3, and the aluminum alloy clamp ring 5 and the embedded ring 3 are both sleeved on the side rope 4, the connecting end of the side rope 4 is provided with a sleeve ring 6, the end of the sleeve ring 6 is installed with a shackle 7, and one side of the sleeve ring 6 is provided with an auxiliary rope 8;

[0033] It also includes a replacement step 9, which includes a plate 91, an inch plate 1 92 and an inch plate 2 93. The four corners on the top of the plate 91 are penetrated by grooves 911, and the grooves 911 are connected to the long sides of the plate 91. The sides where the inch plate 1 92 and the inch plate 2 93 are close to each other are each provided with a semicircular groove 95. The hole formed by the two semicircular grooves 95 is adapted to the groove 911, and the hole formed by the two semicircular grooves 95 and the groove 911 are both mounted on the side rope 4. After the inch plate 1 92 and the inch plate 2 93 are spliced, they are arranged on both sides of the bottom of the plate 91, and the plate 91 and the inch plate 1 92 as well as the plate 91 and the inch plate 2 93 are detachably connected by connecting members 94.

[0034] It should be noted that the connection end of the side cable 4 is the installation position of the rope ladder.

[0035] In this embodiment, the implementation scenario is specifically as follows: when the tread of the rope ladder is damaged and needs to be replaced, the damaged tread is replaced with a replacement tread 9;

[0036] The steps of replacing the step 9 are as follows: first, remove the damaged step between the aluminum alloy clamp ring 5 and the insert ring 3;

[0037] Next, insert the rope segment between the aluminum alloy clamp ring 5 and the insert ring 3 into the groove 911 from the side opening of the groove 911 of the plate 91, and repeat the operation until the four grooves 911 of the plate 91 are all passed through the side rope 4;

[0038] Then, the inch plate 1 92 and the inch plate 2 93 are combined so that the semicircular grooves 95 of the two overlap to form a hole, and then the overlapped hole is sleeved on the side cable 4;

[0039] Finally, after the inch plate 1 92 and the inch plate 2 93 are combined, the screw holes on the plate 91 correspond to the screw holes on the inch plate 1 92 and the inch plate 2 93, and the plate 91 and the inch plate 1 92 are fixed together using the connecting member 94 (bolts or screws), and the plate 91 and the inch plate 2 93 are also fixed together;

[0040] Through the above-mentioned replacement steps, a new replacement step 9 is replaced, which solves the problem that the existing rope ladder cannot be replaced. In addition, the rope ladder is designed with a structure with grooves at both ends and reinforced upper and lower inch plates, which can complete the replacement of damaged pedals while ensuring the load-bearing requirements, thereby extending the service life of the rope ladder.

[0041] The rope ladder also includes a suspension part and a boarding part, and the boarding part and the suspension part are continuously distributed along the connection end of the side rope 4 toward the suspension end, and the steps include non-replaceable steps and replaceable steps 2, the non-replaceable steps include rubber steps 1, and the rubber steps 1 are arranged in the suspension part, and the replaceable steps 2 are arranged in the boarding part;

[0042] It should be noted that in actual use, one end of the rope ladder is usually fixed on the equipment or installation location, and the other end is suspended. Therefore, by designing the steps of the suspended part as non-replaceable rubber steps 1, the problem of metal or wooden steps being easily damaged by collision in the suspended state can be effectively reduced.

[0043] A clamping block 951 is integrally formed on the inner side of the semicircular groove 95, and the clamping block 951 is a fan-shaped wedge block inclined downward;

[0044] It should be noted that the downwardly inclined clamping block 951 is designed. During the installation of the replacement step 9, the clamping block 951 clamps the rope segment of the side cable 4, which is beneficial to improve the locking friction between the replacement step 9 and the side cable 4. During the use of the replacement step 9, the replacement step 9 is subjected to the downward gravity of the person, so that the clamping block 951 can be downwardly embedded in the rope segment of the side cable 4. Furthermore, during use, the more the replacement step 9 is used, the tighter it is with the side cable 4, thereby improving the safety performance.

[0045] A safety mechanism is provided between the embedded ring 3 and the side cable 4. The safety mechanism includes a ring sleeve 31, which is embedded on the outside of the embedded ring 3. The side cable 4 and the ring sleeve 31 are arranged concentrically. A plurality of racks 34 arranged in an array are provided on the inner side of the ring sleeve 31 to slide inwardly. A clamping plate 35 is fixedly connected to one end of the rack 34 close to the side cable 4. When the side cable 4 breaks at the clamping block 951, the rack 34 moves inwardly and the clamping plate 35 clamps the side cable 4.

[0046] It should be noted that the side rope 4 may break at various positions due to stress, but due to the provision of the clamping block 951, if the side rope 4 breaks, the probability of the part of the side rope 4 clamped by the clamping block 951 breaking is much greater than that of other rope segments.

[0047] A concentric inner gear ring 32 is rotatably installed on the inner side of the ring sleeve 31, and a gear 33 is movably installed on the inner side of the ring sleeve 31. The gear 33 is meshed and connected with the inner gear ring 32, and the rack 34 is also meshed and connected with the gear 33. The inner gear ring 32 and the rack 34 are respectively meshed with the gear teeth at different axial positions of the gear 33. A trigger mechanism 36 is also installed on the inner side of the ring sleeve 31. When the side cable 4 breaks at the block 951, the trigger mechanism 36 drives the inner gear ring 32 to rotate, the rack 34 moves centripetally, and the clamping plate 35 clamps the side cable 4.

[0048] The trigger mechanism 36 includes a pull rod 361, which movably passes through the ring sleeve 31, and the end of the pull rod 361 located in the ring sleeve 31 is fixedly connected to a wedge block 1 362, and one side of the inner gear ring 32 is fixedly connected to a wedge block 2 363, and the wedge block 1 362 is adapted to the wedge block 2 363. When the pull rod 361 pulls the wedge block 1 362 axially, the wedge block 2 363 rotates with the inner gear ring 32.

[0049] The end of the pull rod 361 outside the ring sleeve 31 is detachably connected to the connecting member 94 .

[0050] The end of the pull rod 361 outside the ring sleeve 31 is provided with a threaded portion, and the connecting member 94 and the pull rod 361 are connected via a threaded sleeve.

[0051] In this embodiment, the implementation scenario is specifically as follows: by setting a safety mechanism, if the side rope 4 of the rope ladder breaks in the semicircular groove 95, the top of the pull rod 361 is fixedly connected to one end of the connecting piece 94, so the position of the pull rod 361 will not change, but because the embedded ring 3 under the replacement step 9 is fixed to the side rope 4 below, the side rope 4 breaks, the embedded ring 3 drives the ring sleeve 31 to fall, the relative position of the wedge block 1 362 and the wedge block 2 363 changes, the wedge block 2 363 falls with the ring sleeve 31, and is squeezed by the wedge block 1 362, so that The wedge block 363 drives the inner gear ring 32 to rotate counterclockwise, and the inner gear ring 32 drives the gear 33 to rotate. The gear 33 then drives the rack 34 and the clamping plate 35 to move centripetally. The clamping plate 35 clamps the broken side rope 4 to prevent the side rope 4 from being pulled out from the embedded ring 3, thereby providing support force at the moment of the side rope 4 breaking, pulling the broken side rope 4, and avoiding the side rope 4 from breaking directly, providing reaction time for people who are using the rope ladder, reducing the occurrence of safety accidents, and providing people with the ability to react and save themselves when a safety accident occurs.

[0052] The surface of the pressing plate 35 is provided with a friction portion, which is beneficial to improving the friction force.

[0053] The top of the plate 91 is provided with an anti-slip protrusion 912, which is helpful to improve the friction.

[0054] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
