[0025] Embodiment 1

[0026] This embodiment provides a rest platform for a straight ladder, as Figures 1 - 5 shown, including a fixed chassis 1. The fixed chassis 1 is provided with a fixing component, and the fixed chassis can be detachably connected to the straight ladder through the fixing component. The top of the fixed chassis 1 is rotatably connected with a support plate 2. When the support plate 2 rotates to the horizontal state, it can serve as a temporary rest platform for the climbing personnel. When the support plate 2 rotates to the vertical state, it does not hinder the climbing personnel from climbing the straight ladder. One end of the support plate 2 is rotatably connected to the top of the fixed chassis 1, and the other end is hinged to one end of a link rod 3. The other end of the link rod 3 is hinged to a first pin shaft 4. The first pin shaft 4 extends into a slide groove 5 provided in the fixed chassis 1. The slide groove 5 is arranged along the length direction of the fixed chassis 1, that is, along the vertical direction. The first pin shaft 4 is slidably connected to the fixed chassis 1 through the slide groove 5. When the support plate 2 rotates to the horizontal state, the first pin shaft 4 falls to the bottom of the slide groove 5. The fixed chassis 1 supports the link rod 3 through the slide groove 5, and then supports the support plate 2, so that the support plate 2 can bear the pressure load when serving as a temporary rest platform.

[0027] One end of the support plate 2 is rotatably connected to the fixed chassis 1, and the other end is also movably connected with a fixed hook 6. The fixed hook 6 can hook the straight ladder when the support plate 2 is in the vertical state, so that the support plate 2 can maintain the vertical state.

[0028] In this embodiment, two fixed chassis 1 are provided. The tops of the two fixed chassis 1 are both connected to one end of the support plate 2 and rotatably connected to the support plate 2. Both of the two fixed chassis 1 are provided with fixing components and connected with link rods 3. Taking one of the fixed chassis 1 as an example for description.

[0029] The fixed chassis 1 is made of an L-shaped plate and includes a first chassis part and a second chassis part that are perpendicular to each other. The first chassis part is used to fit the straight ladder, and the second chassis part is provided with a slide groove 5.

[0030] The fixed component includes a first hook 7 fixed to the upper part of the outer side surface of the first chassis part and a second hook 8 fixed to the lower part of the outer side surface of the first chassis part. The first hook 7 and the second hook 8 can be hooked on the straight ladder. A locking rod 9 is provided at the bottom of the outer side surface of the second chassis part. The locking rod 9 is located below the second hook 8. The locking rod 9 is detachably and fixedly connected to the second chassis part. Specifically, a bolt 10 passes through the locking rod 9 and the second chassis part, and a nut is screwed on the bolt 10. The locking rod 9 is detachably and fixedly connected to the second chassis part through the bolt 10 and the nut.

[0031] A space for the climbing rod 11 of the straight ladder to pass through is formed between the locking rod 9 and the second hook 8. After the climbing rod 11 of the straight ladder passes through the space between the locking rod 0 and the second hook 8, it is clamped and fixed by the locking rod 9 and the second hook 8, realizing the fixation of the bottom of the fixed chassis 1 to the straight ladder. The first hook 7 on the upper part of the fixed chassis 1 hooks the straight ladder to prevent the entire rest platform from tipping over.

[0032] The support plate 2 is a rectangular plate, and its corners are rounded to prevent collision damage to the climbing personnel. A rectangular weight-reducing hole is provided at the center of the support plate 2 to reduce the weight of the support plate and facilitate the climbing personnel to flip the support plate.

[0033] A second pin shaft 12 is fixed to the top end of the second chassis part. The second pin shaft 12 is perpendicular to the second chassis part. The second pin shaft 12 extends into the space between the two first ear plates 13. The first ear plates 13 are fixed to the bottom surface of the end of the support plate 2. The second pin shaft 12 is rotatably connected to the two first ear plates 13, thereby realizing the rotational connection between the support plate 2 and the fixed chassis 1.

[0034] One end of the connecting rod 3 is rotatably connected to a first pin shaft 4, and the other end is fixed with a third pin shaft 14. The other end of the connecting rod 3 extends into the space between the two second ear plates 15. The third pin shaft 14 is rotatably connected to the second ear plates 15, thereby realizing the rotational connection between the connecting rod 3 and the support plate 2.

[0035] One end of the first pin shaft 4 is hinged to the connecting rod 3, and the other end passes through the second chassis part through a sliding groove 5. A limit stop 16 is provided at the end of the first pin shaft 4 passing through the second chassis part. The diameter of the limit stop 16 is larger than the width of the sliding groove 5 to prevent the first pin shaft 4 from slipping out of the sliding groove 5.

[0036] In this embodiment, among the third pin shafts 14 connected by the two connecting rods 3, at least one third pin shaft 14 is movably connected to the fixed hook 6. In this embodiment, one third pin shaft 14 is movably connected to the fixed hook.

[0037] Specifically, the fixed hook 6 is provided with a long strip hole 17. The third pin shaft 14 passes through the fixed hook 6 through the long strip hole 17, and the third pin shaft 14 is slidably connected to the hole surface of the long strip hole 17, so that the fixed hook 6 can rotate and also move linearly along the axis of the long strip hole 17, thereby realizing the movable connection between the fixed hook 6 and the support plate 2.

[0038] Preferably, a limit stop block is provided at the end of the third pin shaft 14 passing through the fixed hook 6. The diameter of the limit stop block is greater than the width of the long strip hole 17, so that the fixed hook 6 is arranged between the limit stop block and the diameter of the second ear plate 15, preventing the fixed hook 6 from detaching from the third pin shaft.

[0039] Embodiment 2

[0040] This embodiment provides a straight ladder. The straight ladder is composed of a plurality of climbing rods 11 distributed along the climbing direction. The climbing rods 11 are used to be fixed on a building or equipment. The straight ladder is provided with the rest platform for the straight ladder described in Embodiment 1 at a set position. Among them, the first hook 7 and the second hook 8 are respectively hung on the climbing rod 11 of the straight ladder. The bottom of the fixed chassis 1 is fixed and locked with the locking rod 9 through bolts 10 and nuts. The locking rod 9 and the second hook 8 clamp and fix the climbing rod 11, and the first hook 7 prevents the fixed chassis 1 from tipping over.

[0041] The overall width of the rest platform for the straight ladder is smaller than the width of the straight ladder.

[0042] When a climbing person needs to rest, the entire rest platform needs to be unfolded. Then, the fixed hook 6 is separated from the climbing rod 11, and the support plate 2 is rotated. The support plate 2 changes from a vertical state to a horizontal state, the connecting rod 3 moves, and the first pin shaft 4 slides along the chute 5 until it abuts against the bottom of the chute 5, and the support plate 2 is supported by the connecting rod. At this time, the support plate 2 serves as a rest platform, and the climbing person can stand or sit on the support plate 2, which is convenient for the climbing person to take a temporary rest.

[0043] Under normal conditions, the rest platform is in a folded state. The support plate 2 is rotated to a vertical state, and the fixed hook 6 is hung on the climbing rod 11 of the straight ladder. At this time, the support plate 2 is in a vertical state, and the entire rest platform is in a folded state, which is convenient for the climbing person to pass up and down on the straight ladder.

[0044] For the rest platform and the straight ladder of this embodiment, the entire rest platform can be installed on the existing straight ladder as needed, which is convenient for the temporary rest of the climbing person and can be folded. In the folded state, it will not interfere with the climbing of the climbing person, and has strong applicability.

[0045] Although the specific implementation manners of the present utility model have been described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present utility model. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solution of the present utility model are still within the protection scope of the present utility model.
