The utility model discloses a horizontal segment ladder body and vaulting pole structure's setting is placed the horizontal segment ladder body and is come the atress on utility tunnel gallery top bulkhead, need not to lean on utility tunnel's lateral wall, can realize the firm fixed purpose of cat ladder to guarantee staff's personal safety in the maintenance process.
When the ladder works, the horizontal ladder body is rotated to enable an included angle between the two ladder bodies to be a right angle, and the hook is connected with the hanging ring to keep the state. Then, the ladder beam position of the vertical ladder section is adjusted to enable the horizontal ladder section to be placed on the upper end face of the top bulkhead. And then, fixing the ladder body of the vertical section to complete the layout of the folding ladder stand. The problem that the existing ladder stand can not be placed in a position and cannot be moved or unfolded to influence construction is solved.
The vertical section ladder body and the horizontal section ladder body respectively comprise two ladder beams which are distributed in parallel and a plurality of cross rods which are connected between the ladder beams and are distributed in parallel; the lower end of the ladder beam of the vertical ladder body is provided with a horseshoe-shaped ladder foot.
The ladder foot non-slip property of shape of a hoof in this structure is good, can increase the frictional force between folding cat ladder and the utility tunnel diapire to stability in the use has been guaranteed.
Each ladder beam comprises a plurality of sleeves which are 30cm in length and are sleeved, a plurality of adjusting holes which are arranged in a vertical equidistant mode and correspond to the horizontal direction are formed in the upper portion and the lower portion of the side wall of each sleeve, and limiting pins penetrate through the adjusting holes corresponding to any pair of positions of every two adjacent sleeves.
The pin connection mode of the sleeve pipe realizes the telescopic purpose of the whole ladder body, and the ladder body can be folded to a smaller size when not in use; during the use, the staff stands and all pulls out the horizontal segment ladder body at utility tunnel diapire, is connected the position of fixed horizontal segment ladder body through crotch and ring, pulls out the sleeve pipe of vertical segment ladder body after that to the position of the vertical segment ladder body of adjustment makes the horizontal segment ladder body can place in the up end of a cabin wall, and the ladder foot can contact utility tunnel diapire simultaneously. The purpose that the folding crawling ladder can be quickly unfolded in a comprehensive pipe profile with a narrow space is achieved.
The top end part of the ladder beam of the vertical ladder section and the right end part of the ladder beam of the horizontal ladder section are provided with positioning holes which are communicated from front to back; the top of the vertical section ladder body is provided with channel-section steel form link that the opening is down, and the preceding lateral wall and the back lateral wall of link all open and control the through-hole that distributes and fore-and-aft direction position corresponds about two, are located two through-holes on link left and two locating holes of the horizontal section ladder body and have worn first round pin axle, and two through-holes on the link right side and two locating holes of the vertical section ladder body have worn the second round pin axle.
The vertical section ladder body and the horizontal section ladder body are fiber reinforced thermosetting composite material ladder bodies.
The selected fiber reinforced thermosetting composite material overcomes the problems of easy corrosion, poor safety, short service life, great self weight and the like of the traditional ladder body made of metal materials, and has the characteristics of corrosion resistance, fire resistance, light weight, high strength and difficult deformation.
The utility model has the advantages of reasonable design reliably, realized the purpose that the cat ladder freely removed, swiftly expanded, firmly placed in arranging complicated and the narrow and small utility tunnel in space, the non-skid property is good, and stability is strong, has the advantage that conveniently carries, corrosion-resistant, intensity is high, light, prevent fires, can satisfy the maintenance demand of multiple pipeline in the utility tunnel.
