Description

Technical Field

[0001] The present invention relates to the technical field of rope ladders, in particular to a rope ladder with a highly stable structure. Background Art

[0002] A rope ladder, also known as a soft ladder, is a tool used for aerial work and climbing, mainly in the form of a rope. When working on live transmission lines, workers need to enter the electric field via a soft ladder. Since the soft ladder shakes severely when the workers are climbing, there are risks such as the soft ladder falling off and the workers falling. In view of the current situation, it is necessary to realize full fall protection for climbing soft ladders. The tools include an insulated soft ladder head with a lock, a pulley with a lock, and a fall prevention device, which can effectively protect the personal safety of workers and the smooth progress of maintenance work. The rope ladders on the market have a simple structure and often shake when the wind blows. The stability is insufficient, and the relative distance between the pedals or the pedal rods of the existing rope ladders cannot be adjusted, thereby reducing the functional effect of the entire rope ladder. At the same time, when climbing, the existing rope ladder operators are inconvenient to climb because the contact distance between the pedals or the pedal rods and the climbing object is too close, or the foot force is insufficient during the climbing process, which also reduces the stability of the entire rope ladder process. Summary of the Invention

[0003] The object of the present invention is to address the deficiencies of the prior art and provide a rope ladder with a highly stable structure to solve the problems proposed in the above-mentioned background art, such as the rope ladders on the market having a single structure, often shaking when blown by the wind, insufficient stability, and the inability to adjust the relative distances between the pedals or the pedal rods of the existing rope ladders, thereby reducing the functional effect of the entire rope ladder. At the same time, when climbing, the operator of the existing rope ladder has difficulty climbing due to the close contact distance between the pedals or the pedal rods and the climbing object, or the operator does not apply enough force with his feet during climbing, which also reduces the stability of the entire rope ladder.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a rope ladder with a highly stable structure, comprising a rope body structure as a through-connected structure, wherein a stepping structure is provided between the rope body structures to facilitate climbing by an operator;

[0005] The rope structure includes a hemp rope body with fine steel wires woven inside, and the hemp rope body is also woven with a connecting buckle for facilitating the connection of the entire hemp rope body;

[0006] The pedal structure includes a pedal assembly connected to the matching assembly, and the pedal assembly includes a pedal board with a through hole.

[0007] By adopting the above technical solution, the pedal is provided to achieve the effect of opening and installing the device.

[0008] Preferably, a threaded hole is provided through the inner side of the through hole of the pedal, and a slot for convenient snap-in connection is also provided through the rear side of the pedal through the threaded hole.

[0009] By adopting the above technical solution, the provided card slots can achieve a card-fitting connection effect.

[0010] Preferably, a distance block is provided in front of the pedal, and the distance block is also provided with a handwheel threaded rod for rotation adjustment through the threaded hole, and one end of the handwheel threaded rod extends inside the threaded hole and is connected to the bearing seat.

[0011] By adopting the above technical solution, the handwheel threaded rod is provided to achieve the force-rotating adjustment effect.

[0012] Preferably, the bearing seat is connected to the clamping plate, and the clamping plate adopts an "arc-shaped" structure.

[0013] By adopting the above technical solution, the inner and outer rings are connected by the provided bearing seat.

[0014] Preferably, a card block is provided on the rear side of the other pedal and is matched with the card slot, and the card block and the card slot are matched with each other in a symmetrical manner.

[0015] By adopting the above technical solution, the provided clamping blocks can achieve a symmetrical folding and locking effect between the pedals.

[0016] Preferably, the matching component includes a connecting pipe with a hollow structure inside, and a plurality of rubber rings connected to the matching pipe are provided inside the connecting pipe.

[0017] By adopting the above technical solution, the connecting pipe is provided to achieve a penetrating effect.

[0018] Preferably, the threaded holes are provided in two groups of four, and the threaded holes in a single group are symmetrically arranged about the center line of the through hole.

[0019] By adopting the above technical solution, the through holes provided also have the effect of opening and penetrating.

[0020] Preferably, the connecting pipes and the supporting pipes are arranged symmetrically, and a set of connecting pipes and supporting pipes are respectively provided on the upper and lower parts of a single pedal.

[0021] By adopting the above technical solution, the provided matching pipe also achieves a through-matching connection effect.

[0022] Preferably, the diameter interval ratio between the matching tube and the rubber ring is 1.5:1.6.

[0023] By adopting the above technical solution, the provided rubber ring can achieve a penetration connection limiting effect on the matching pipe.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the rope ladder with a highly stable structure,

[0025] (1) This case solves the problem that the rope ladders on the market have a single structure and often shake when the wind blows, which is not stable enough. At the same time, when the operator of the existing rope ladder climbs, the contact distance between the pedal or the pedal rod and the climbing object is too close, which makes it inconvenient for the operator to climb or the foot force is not enough during the climbing process, which also reduces the stability of the entire rope ladder. When the rope ladder is lowered, the distance block contacts the climbing object. When the distance block contacts the climbing object, the distance block forms a relative interval distance between the pedal and the climbing object, so that the operator can step on the pedal over a large area of ​​​​the pedal during the climbing process. At the same time, when the distance block contacts the climbing object, the friction resistance between the pedal and the climbing object is reduced, thereby avoiding the above situation. The above situation is further avoided by using the set distance block;

[0026] (2) The pedal assembly is provided in the pedal structure, thereby solving the problem that the relative distance between the pedals or the pedal rods of the existing rope ladder cannot be adjusted, thereby reducing the functional effect of the entire rope ladder. When the distance between the pedals needs to be adjusted, the operator rotates the handwheel threaded rod through the tool to move. During the force movement of the handwheel threaded rod, the clamping plate is driven to move relative to the force through the bearing seat. During the force relative movement of the clamping plate, the operator manually adjusts the distance between the pedals. The above-mentioned situation is avoided at the same time by using the components in the pedal assembly.

[0027] (3) By providing the supporting components, the card slots and the card blocks in the pedal structure, the problem that the existing rope ladder not only occupies a large storage area but is also inconvenient to carry when stored in a rolled-up manner is solved. When the rope ladder needs to be stored, the operator connects the supporting tube and the connecting tube through a rubber ring. After the connecting tube and the supporting tube are connected, the interval distance between the pedals is shortened. At the same time, when the pedals at both ends are stored and the pedals are folded in half, the card slots and the card blocks on the pedals are engaged and connected. By cooperating with the pedals after being folded in half, the above-mentioned problems are avoided in turn.

[0028] (4) The thin steel wires provided in the rope structure can solve the problem of elastic stretching between the hemp ropes caused by climbers pulling the hemp ropes during the climbing process, and the shaking and instability of the entire rope ladder. When the climbers pull the hemp ropes during the climbing process, the hemp ropes are woven with thin steel wires inside to reduce elastic stretching and avoid the above-mentioned situation.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0039] See also Figure 1-8 , the present invention provides a technical solution: a rope ladder with a highly stable structure, such as Figure 1 、 Figure 2 and Figure 3As shown, it includes a rope structure 1 as a through connection, and the rope structure 1 includes a hemp rope body 101 with fine steel wires 102 woven inside, and the hemp rope body 101 is also woven with a connecting buckle 103 for convenient connection and setting of the overall hemp rope body 101. Among them, the components in the rope structure 1 are all installed and set using existing technology components. When the overall rope structure 1 is woven and set using existing technology components, it not only increases the firmness of the overall rope structure 1 but also reduces the pulling elastic effect between the overall rope structure 1. At the same time, the fine steel wire 102 is woven and set using stainless steel and a diameter of 2MM. This not only reduces the elastic stretching effect of the hemp rope body 101 but also effectively avoids the situation where the overall rope ladder breaks due to wear of the hemp rope body 101.

[0040] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a pedal structure 2 is provided between the rope structure 1 for facilitating the operator's climbing. The pedal structure 2 includes a pedal component 201 connected to the matching component 202, and the pedal component 201 includes a pedal board 2011 with a through hole 2012. The pedal board 2011 is also provided with existing technical materials. The pedal board 211 provided with existing technical materials not only has the effect of opening the pedal board 211 but also has the effect of installing the pedal board 2011.

[0041] The above scheme further provides that the pedal 2011 is provided with a threaded hole 2013 passing through the inner side of the through hole 2012, and the threaded holes 2013 are provided in two groups of four, and a single group of threaded holes 2013 is symmetrically arranged about the center line of the through hole 2012. When two groups of four are provided through the above structure, this not only reflects the penetration of the above structure, but also reflects the threaded connection effect of the above structure. Moreover, when a single group of threaded holes 2013 is symmetrically arranged about the center line of the through hole 2012, this effectively enables a group of clamping plates 2018 to be provided inside the single through hole 2012, thereby playing an effect of adjusting the clamping and loosening displacement of the hemp rope body 101 passing through. Moreover, the threaded hole 2013 is also provided with a card slot 2014 for convenient snap-fit ​​connection through the rear side of the pedal 2011. Among them, the single pedal 2011 is also provided with a group of card slots 2014, and the symmetrically provided card slots 2014 are used to achieve a stable snap-fit ​​connection effect between the pedals 2011.

[0042] The above scheme is further developed in that a distance block 2015 is provided in front of the pedal 2011, and the distance block 2015 is also provided with a handwheel threaded rod 2016 for rotation adjustment through the threaded hole 2013. At the same time, one end of the handwheel threaded rod 2016 extends inside the threaded hole 2013 and is connected to the bearing seat 2017. The handwheel threaded rod 2016 and the bearing seat 2017 constitute a rotation adjustment structure, and the rotation adjustment structure is utilized to change the relative interval distance between the clamping plates 2018 and effectively change the relative interval distance between the pedals 2011.

[0043] The above scheme is further improved. The bearing seat 2017 is connected to the clamping plate 2018, and the clamping plate 2018 adopts an "arc-shaped" structure. The number of clamping plates 2018 is symmetrically matched with the number of handwheel threaded rods 2016. When the above components are symmetrically arranged, the hemp rope body 101 can be effectively clamped and fixed.

[0044] The above solution is further improved in that a block 2019 is provided on the rear side of the other pedal 2011 and is engaged with the slot 2014, and the block 2019 and the slot 2014 are engaged with each other in a symmetrical manner.

[0045] In the above scheme, when it is necessary to change the relative interval distance between the pedals 2011, the operator uses a tool to rotate the handwheel threaded rod 2016 to drive the bearing seat 2017 and the clamping plate 2018 to move relative to the through hole 2012 under force. When the clamping plate 2018 is under force and moves relative to the hemp rope body 101, the operator manually adjusts the movement of the pedals 2011 to change the interval distance between the pedals 2011, thereby repeating the above-mentioned direction operation and fixing it.

[0046] The supporting component 202 includes a connecting tube 2021 with a hollow structure, and a plurality of rubber rings 2022 connected to the supporting tube 2023 are provided inside the connecting tube 2021. The connecting tube 2021 and the supporting tube 2023 are symmetrically arranged, and a set of connecting tubes 2021 and supporting tubes 2023 are respectively provided on the upper and lower parts of the single pedal 2011. When the above two are arranged in a symmetrical manner, not only the symmetry of the installation of the above two is reflected, but also the connectivity and adjustment practicality of the above two after installation are reflected. In addition, a set of connecting tubes 2021 and supporting tubes are respectively provided on the upper and lower parts of the single pedal 2011. 2023, it is convenient for the above two to be set separately up and down, and effectively achieve the same matching connection setting effect for other connecting pipes 2021 and supporting pipes 2023. The diameter range ratio between the supporting pipe 2023 and the rubber ring 2022 is 1.5:1.6. When the diameter ratio of the above two is 1.5:1.6, it can be seen that the outer ring diameter of the supporting pipe 2023 is 0.1 smaller than the inner ring diameter of the rubber ring 2022. When the diameter ratio between the above two is relatively small, it is convenient for the above two to be set in a matching and tight manner, which not only achieves a quick connection setting effect between the above two, but also achieves a quick disassembly effect between the above two.

[0047] In the above scheme, when the rope ladder needs to be stored, the operator manually holds the matching tube 2023 and the connecting tube 2021 so that the two are subjected to relative movement, and the hemp rope body 101 is stored between the matching tube 2023 and the connecting tube 2021. When the matching tube 2023 is in contact with the rubber ring 2022 under force, they are tightly matched and connected. When the pedals 2011 at both ends are stored, the operator folds the pedals 2011 at both ends in half so that the card block 2019 is engaged with the card slot 2014 for matching connection, thereby facilitating the operator to store, carry and use the entire rope ladder.
