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

Inspection shaft cat ladder assembly

Technical field

The present invention relates to a kind of cat ladder assembly in municipal administration inspection shaft.

Background technology

Existing municipal administration inspection shaft or without cat ladder, needs to carry bamboo ladder and enters in inspection shaft, and bamboo ladder is in the tilted peace of inspection shaft Dress, takies work space, is unfavorable for maintenance activity；Part municipal administration inspection shaft is provided with cat ladder, but due to for a long time need not, can lead Cause mossy skid, raindrop erosion, cause that cat ladder is insecure causes danger.

Summary of the invention

For above-mentioned deficiency, it is desirable to provide a kind of cat ladder assembly being exclusively used in inspection shaft, both saved space, profit In maintenance activity, cat ladder mossy is not the most made to get rusty.

To this end, the technical solution adopted in the present invention is: a kind of inspection shaft cat ladder assembly, including cat ladder, along inspection shaft Wherein one the upper and lower equi-spaced apart of sidewall arrange embedded bracket, described cat ladder adjacent two ladder step between distance with adjacent pre-buried The distance of frame is equal, and the width of described embedded bracket is less than the width of cat ladder, and embedded bracket is horizontally disposed with, the front end of embedded bracket It is positioned at the sidewall of inspection shaft outer and with the first anticreep eave tile, to guarantee that cat ladder is linked into after the first anticreep eave tile in use Not falling out, the rear end of embedded bracket is positioned at the sidewall of inspection shaft and with the second anticreep eave tile, to prevent by pre-during external force The front end burying support loosens.

Preferred as such scheme, described embedded bracket is the horizontally disposed " u "-shaped part using plastic-steel bending, The two ends of " u "-shaped part constitutes the first anticreep eave tile after the most vertically bending, the middle part of " u "-shaped part is bent into the circle of opening upwards Angle [alpha] ＞ of arc and circular arc 180 °, thus constitute the second anticreep eave tile, the cross section of the ladder step of described cat ladder is circular. Manufacture easy to process, low cost, good anti-drop effect.

Further, described cat ladder uses light material to make, it is simple to carry.

Beneficial effects of the present invention: by arranging built-in fitting in inspection shaft, carries during operation and matches with built-in fitting Cat ladder is interlocked with built-in fitting, has both saved space, beneficially maintenance activity, does not the most make cat ladder mossy get rusty.

Detailed description of the invention

Below by embodiment and combine accompanying drawing, the invention will be further described:

Shown in Fig. 1, Fig. 2, a kind of inspection shaft cat ladder assembly, including cat ladder 1, upper and lower along an inspection shaft wherein sidewall The embedded bracket 2 that equi-spaced apart is arranged.

Distance between the adjacent two ladder steps of cat ladder 1 is equal with the distance of adjacent embedded bracket 2, and the width of embedded bracket 2 is little In the width of cat ladder 1, to guarantee that cat ladder 1 mates with embedded bracket 2, just each ladder step of cat ladder 1 is linked into correspondence successively In embedded bracket 2.

Embedded bracket 2 is horizontally disposed with, and the front end of embedded bracket 2 is positioned at outside the sidewall of inspection shaft and with the first anticreep eave tile 2a, to guarantee that cat ladder 1 does not in use fall out after being linked into the first anticreep eave tile 2a.The rear end of embedded bracket 2 is positioned at inspection In looking into the sidewall of well and with the second anticreep eave tile 2b, to prevent the front end by embedded bracket during external force 2 from loosening.

Shown in Fig. 3, Fig. 4, embedded bracket 2 is the horizontally disposed " u "-shaped part using plastic-steel bending, " u "-shaped The two ends of part constitutes the first anticreep eave tile 2a after the most vertically bending, the middle part of " u "-shaped part is bent into the circular arc of opening upwards Angle [alpha] ＞ of shape and circular arc 180 °, thus constitute the second anticreep eave tile 2b；Correspondingly, the cross section of the ladder step of cat ladder 1 is circle Shape.When taking out cat ladder 1, it is necessary to cat ladder 1 is elapsed (including the passage of horizontally and vertically both direction) to opening direction, Fang Keshun Profit takes out cat ladder 1, installs cat ladder 1 and takes out cat ladder 1 contrast.

It addition, as it is shown in figure 5, cat ladder 1 uses light material to make.

When making inspection shaft, pre-buried equidistant embedded bracket 2.Meanwhile, the cat ladder 1 one equidistant with embedded bracket 2 is made Part.When needs enter inspection shaft Inspection, it is only necessary to cat ladder 1 is linked in the first anticreep eave tile 2a of embedded bracket 2 i.e. Can.

Claims
