Problems solved by technology

[0002] Existing municipal inspection wells or without ladders need to bring their own bamboo ladders into the inspection wells. Bamboo ladders are installed obliquely in the inspection wells, occupying work space and are not conducive to maintenance operations; some municipal inspection wells are equipped with climbing ladders, but due to long-term use, it will Lead to moss slipping, rain corrosion, lead to dangerous climbing ladder is not firm

Embodiment Construction

[0013] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0014] combine figure 1 , figure 2 As shown, an inspection well climbing ladder assembly includes a climbing ladder 1 and pre-embedded brackets 2 arranged at equal intervals up and down along one side wall of the inspection well.

[0015] The distance between two adjacent steps of the ladder 1 is equal to the distance between the adjacent embedded bracket 2, and the width of the embedded bracket 2 is smaller than the width of the ladder 1, so as to ensure that the ladder 1 matches the embedded bracket 2, and the Each step is hung into the corresponding embedded bracket 2 in turn.

[0016] The pre-embedded support 2 is arranged horizontally, and the front end of the pre-embedded support 2 is located outside the side wall of the inspection well and has a first anti-off hook 2a, so as to ensure that the climbing ladder 1 is hung into the first anti-off ho...

Abstract

The invention discloses a manhole ladder assembly comprising a ladder, embedded supports arranged from top to bottom along one side of the manhole at equal intervals, and the distance between the two ladder steps is equal to that between the adjacent embedded supports. The width of the embedded supports is smaller than that of the ladder. The embedded supports are horizontally arranged. The front ends of the embedded supports are located outside the sidewall of the manhole and are provided with first anti-loose hooks to ensure that the ladder is inserted into the first anti-loose hooks without looseness during use. The rear ends of the embedded supports are located in the sidewall of the manhole and have second anti-loose hooks to prevent the front ends of the embedded supports from loosening when subjected to external force. By arranging the embedded parts in the manhole, the ladder that is carried during operation and matches with the embedded parts is engaged with the embedded parts, which saves space and facilitates the maintenance work, and the ladder will rust and moss.

Description

technical field [0001] The invention relates to a climbing ladder assembly used in municipal inspection wells. Background technique [0002] Existing municipal inspection wells or without ladders need to bring their own bamboo ladders into the inspection wells. Bamboo ladders are installed obliquely in the inspection wells, occupying work space and are not conducive to maintenance operations; some municipal inspection wells are equipped with climbing ladders, but due to long-term use, it will Lead to moss slipping, rain corrosion, resulting in dangerous climbing ladder is not firm. Contents of the invention [0003] In view of the above disadvantages, the present invention aims to provide a ladder assembly specially used in inspection wells, which not only saves space, but also facilitates maintenance operations, and does not cause moss and rust on the ladder. [0004] For this reason, the technical solution adopted by the present invention is: an inspection well climbing...
