Description

A kind of Municipal Engineering Construction inspection well ladder
Technical field
The utility model belongs to construction equipment field, and in particular to a kind of Municipal Engineering Construction inspection well ladder.
Background technique
Many underground pipings, such as sewer, underground gas pipeline, water supply pipe, power pipe are had in urban construction Road, communication conduit, national defence pipeline etc., these pipelines lead to the outlet on ground every a Duan Yaoyou mono-, by pipeline to ground This section is known as inspection shaft, and inspection shaft is based on circle.Part catch pit port has just set ladder in first stage of construction, but this construction Cost is relatively high, and therefore, most of inspection shaft will not pre-install ladder, and construction personnel uses rope ladder or more when construction more. Although rope ladder is convenient for carrying, but softer, is easy when use to shake, inconvenient, and safety coefficient is lower.It is other Inspection well ladder, which is used, is hung on well head for ladder, falls off in use process due to shaking or moving to cause to link up with, causes to cause to apply The risk that worker person falls.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of Municipal Engineering Construction inspection well ladder, the process used It will not shake and move, security performance is improved.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: Municipal Engineering Construction basement Well ladder, including support ring are equipped with the ladder ontology being vertically arranged in support ring, ladder ontology include two vertical support rods and The cross bar between two support rods is arranged in several, is set on the upside of support ring there are two connecting rod, connecting rod connection is horizontally disposed Clamping bar, support ring is equipped with several structures of shoring being used to support in inspection shaft inner wall, and the structure of shoring includes and support Screw rod that ring is threadedly coupled and be arranged in screw rod end shore seat.
In preferred scheme, the cross bar is to the curved arcuate structure of inspection shaft inner wall.
In preferred scheme, including extend ladder, the upper end for extending ladder is equipped with hook, and the hook is fastened on support rod lower end Mounting hole in.
In preferred scheme, described two support rods are equipped with side rail, and back guardrail is equipped between side rail.
In preferred scheme, the bottom for shoring seat is equipped with rubber pad.
In preferred scheme, the upper end of the support rod is protruded above inspection shaft.
A kind of Municipal Engineering Construction inspection well ladder provided by the utility model, by the clamping bar being arranged in support ring, Support ring frame is located at inspection shaft upper end, is held out against support ring in inspection shaft inner wall by shoring structure, the left and right for limiting support ring is moved It is dynamic, never guarantee the stability of ladder ontology, reduces shaking and movement, improve safety.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples:
Fig. 1 is the top view of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Fig. 3 is the scheme of installation for extending ladder.
In figure: support ring 1, support rod 2, cross bar 3, connecting rod 4 are clamped bar 5, inspection shaft 6, and screw rod 7 shores seat 8, extend ladder 9, hook 10, mounting hole 11, side rail 12, back guardrail 13.
Specific embodiment
As shown in Figure 1 and 2, a kind of Municipal Engineering Construction inspection well ladder, including support ring 1, interior be equipped with of support ring 1 set vertically The ladder ontology set, ladder ontology includes two vertical support rods 2 and the cross bar between two support rods 2 is arranged in several 3, it sets on the upside of support ring 1 there are two connecting rod 4, two connecting rods 4 are symmetrical arranged, and connecting rod 4 connects horizontally disposed clamping bar 5, clamping bar 5 is erected at the outer of inspection shaft 6, and support ring 1 is equipped with several structures of shoring being used to support in 6 inner wall of inspection shaft, institute It states and shores that structure includes the screw rod 7 being threadedly coupled with support ring 1 and be arranged in 7 end of screw rod shore seat 8, support ring 1 Diameter is less than the diameter of inspection shaft 6, makes to shore seat 8 by rotating screw rod 7 and holds out against 6 inner wall of inspection shaft, plays limitation to support ring 1 and makees With preventing ladder ontology from shaking and mobile, improve safety and stability.
It protrudes above inspection shaft 6 upper end of the support rod 2.Support when construction personnel being facilitated to go into the well.
The bottom for shoring seat 8 is equipped with rubber pad.On the one hand buffer function is played, prevents the damage to 6 inner wall of inspection shaft, On the other hand it shores structure and holds out against extruding rubber pad, improve the frictional force with 6 inner wall of inspection shaft.
The cross bar 3 is to the curved arcuate structure of 6 inner wall of inspection shaft.Cross bar 3 is set as arcuate structure, utilizes the knot of inspection shaft Structure provides biggish space for construction personnel's climbing, prevents cross bar 3 from interfering construction personnel's climbing, reduces cross bar 3 and collide with constructor The knee of member.
Preferably, as shown in figure 3, including extending ladder 9, the upper end for extending ladder 9 is equipped with hook 10, and the hook 10 is fastened on In the mounting hole 11 of 2 lower end of support rod.When the length of ladder ontology is inadequate, extend ladder 9 in fact by connecting in 2 lower end of support rod The extension of existing ladder body, use are more flexible.
Described two support rods 2 are equipped with side rail 12, and back guardrail 13 is equipped between side rail 12.Ladder ontology, side shield Column 12 and back guardrail 13 form closed climbing channel, prevent construction personnel from falling, improve safety.To reduce 12 He of side rail The interference of 13 pairs of guardrail constructions of back, ladder ontology lower end close on 6 bottom position of inspection shaft and are not provided with side rail 12 and back guardrail 13.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model System, the technical solution that the protection scope of the utility model should be recorded with claim, the technical solution recorded including claim The equivalents of middle technical characteristic are protection scope.Equivalent replacement i.e. within this range is improved, also in the utility model Protection scope within.
