Description

A kind of catch pit port cat ladder
Technical field
The present invention relates to municipal works field, particularly relate to a kind of catch pit port cat ladder.
Background technology
Urban construction has a lot of underground piping, such as sewer, underground gas pipeline, water supply pipe, power pipe, communication conduit, national defence pipeline etc., these pipelines to have an outlet leading to ground every one section, it is referred to as inspection shaft by this section of pipeline to ground, catch pit port is the most concordant with ground, it is thus desirable to a lid, for the lid of lid inspection shaft, it is inspection well cover.Inspection well cover is generally made with materials such as reinforced concrete, metal, reinforced plastics, and shape is based on circular and square.
Under normal circumstances, catch pit port is all closed with inspection well cover, prevent pedestrian from falling into, it is ensured that safety.During construction, workmen can erect warning rail in catch pit port surrounding, then takes off inspection well cover and constructs.
But, due to varying in size of underground piping, therefore, distance between inspection well cover from underground piping is the most different, and workmen is upper and lower for convenience, and some catch pit port has just set cat ladder at the initial stage built, but this construction cost is higher, therefore, major part catch pit port will not pre-install cat ladder, and workmen's many uses rope ladder construction when is upper and lower.Although rope ladder is convenient for carrying, but soft, easily rock during use, the most convenient.
Summary of the invention
The technical problem to be solved is to provide a kind of convenient construction personnel and the good catch pit port cat ladder of steadiness.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions: a kind of catch pit port cat ladder, has main ladder, the top of described main ladder is provided with flanging, bottom part down connects extension ladder, and the top of described extension ladder is provided with hook, and extension ladder is hung on main ladder by hook;The end of described flanging is provided with card extension bar, and the two ends of described card extension bar extend in outside the both sides of flanging, is provided with symmetrical slow pressure device bottom these two ends;Described slow pressure device is made up of spring and presser feet, and the top of described spring is welded admittedly with card extension bar, and the top of bottom and presser feet is welded admittedly;The top of described presser feet is fixedly installed lower limit guide rod, it is fixedly installed upper limit guide rod on corresponding card extension bar, described upper limit guide rod and lower limit guide rod are symmetrical above and below, are provided with spacing between its plane of symmetry, and described spring is wrapped in upper limit guide rod and the outside of lower limit guide rod.
As preferably, the two bottom sides of described main ladder and extension ladder is provided with two symmetrical compression bars, and described compression bar and flanging are in homonymy, corresponding up and down.
As preferably, described compression bar connects by being admittedly welded in the torr joint of main ladder and extension ladder two bottom sides;The end of described torr joint is in " ∪ " type, and one end of described compression bar is positioned at torr joint, is flexibly connected by bearing pin between its with torr joint.
As preferably, the other end of described compression bar correspondence torr joint is provided with feet, and between described feet and compression bar, logical ball cup is flexibly connected.
Compared with prior art, the invention have benefit that: this catch pit port cat ladder simple in construction, its top card is connected on outside catch pit port, lower section is supported by compression bar, good stability, and convenient construction personnel are upper and lower, and cat ladder length, strong adaptability can be increased according to the height of inspection shaft.

Detailed description of the invention
Describe the present invention with detailed description of the invention below in conjunction with the accompanying drawings.
Shown in Fig. 1 and Fig. 2, a kind of catch pit port cat ladder, has main terraced 1, and the described main top of terraced 1 is provided with flanging 2, and bottom part down connects extension ladder 4, and the top of described extension ladder 4 is provided with hook 9, and extension ladder 4 is hung on main terraced 1 by hook 9;The end of described flanging 2 is provided with card extension bar 3, and the two ends of described card extension bar 3 extend in outside the both sides of flanging 2, are provided with symmetrical slow pressure device bottom these two ends;As it is shown on figure 3, described slow pressure device is made up of spring 11 and presser feet 10, the solid weldering of the top of described spring 11 and card extension bar 3, the top of bottom and presser feet 10 is welded admittedly;The top of described presser feet 10 is fixedly installed lower limit guide rod 13, it is fixedly installed upper limit guide rod 12 on corresponding card extension bar 3, described upper limit guide rod 12 and lower limit guide rod 13 are symmetrical above and below, being provided with spacing between its plane of symmetry, described spring 11 is wrapped in upper limit guide rod 12 and the outside of lower limit guide rod 13.In order to there is spacing with inspection shaft road after main terraced 1 and extension ladder 4 are installed, convenient construction personnel up and down and improve stability, described main terraced 1 is provided with two symmetrical compression bars 5 with the two bottom sides extending ladder 4, and described compression bar 5 is in homonymy with flanging 2, corresponding up and down.Being converted into by compression bar 5 for convenience, described compression bar 5 connects by being admittedly welded in the torr joint 6 of main terraced 1 and terraced 4 two bottom sides of extension;The end of described torr joint 6 is in " ∪ " type, one end of described compression bar 5 is positioned at torr joint 6, it is flexibly connected by bearing pin 7 between its with torr joint 6, the other end of described compression bar 5 corresponding torr joint 6 is provided with feet 8, between described feet 8 and compression bar 5, logical ball cup is flexibly connected, fitting tightly of feet 8 and inspection shaft road wall can be realized, make main terraced 1 and extension ladder 4 more firm.
During use, inspection well cover on catch pit port is taken off, then catch pit port is put into by main terraced 1, the arranging of main terraced 1 top flap 2 can make main terraced 1 with the wall distance in inspection shaft road closer to, thus increase the turnover area of workmen on catch pit port, main terraced 1 is connected to the outside of catch pit port by the card extension bar 3 on flanging 2, and makes have slow pressure between main terraced 1 and ground by the spring 11 on card extension bar 3 and presser feet 10, it is to avoid hard contact and the vibration that causes;The compression bar 5 on joint 6 is ask to put down bottom main terraced 1, the feet 8 making compression bar 5 end withstands inspection shaft road wall, feet 8 is connected with compression bar 5 by ball cup, feet can be made to adapt to the inspection shaft road wall of different angles, make main terraced 1 more stable while, main terraced 1 is made to keep certain distance with inspection shaft road wall, it is to avoid inconvenience workmen is upper and lower because of the too near of patch;If the height in inspection shaft road is higher, can main terraced 1 time successively hang adapt to quantity extension ladder 4, and extension ladder 4 makes it keep certain distance with inspection shaft road wall and improve its stability by the compression bar 5 bottom it simultaneously, workmen can be realized after installation upper and lower.
This catch pit port cat ladder simple in construction, its top card is connected on outside catch pit port, and lower section is supported by compression bar 5, good stability, and convenient construction personnel are upper and lower, and can increase cat ladder length, strong adaptability according to the height of inspection shaft.
It is emphasized that: be the most only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction, every any simple modification, equivalent variations and modification made above example according to the technical spirit of the present invention, all still falls within the range of technical solution of the present invention.
