Detailed description of the invention
With detailed description of the invention, the utility model is described in detail 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, bottom
Lower section is connected with 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, this two bottom
Portion is provided with symmetrical slow pressure device；As it is shown on figure 3, described slow pressure device is made up of spring 11 and presser feet 10, described bullet
The solid weldering of the top of 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
Position guide rod 13, corresponding card extension bar 3 is fixedly installed upper limit guide rod 12, and described upper limit guide rod 12 and lower limit are led
Bar 13 is symmetrical above and below, is provided with spacing between its plane of symmetry, and described spring 11 is wrapped in upper limit guide rod 12 and lower limit guide rod
The outside of 13.In order to have spacing with inspection shaft road after main terraced 1 and extension ladder 4 are installed, convenient construction personnel up and down and improve steady
Qualitative, described main terraced 1 and the two bottom sides of extension ladder 4 be provided with two symmetrical compression bars 5, described compression bar 5 with
Flanging 2 is in homonymy, corresponding up and down.Converting into compression bar 5 for convenience, described compression bar 5 is by being admittedly welded in main terraced 1 He
The torr joint 6 extending terraced 4 two bottom sides connects；The end of described torr joint 6 is in " ∪ " type, and one end of described compression bar 5 is positioned at
In torr joint 6, being 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 arranged
Having feet 8, between described feet 8 and compression bar 5, logical ball cup is flexibly connected, it is possible to achieve feet 8 is tight with inspection shaft road wall
Closely connected conjunction, make main terraced 1 and extension ladder 4 more firm.
During use, the inspection well cover on catch pit port is taken off, then put into catch pit port, main terraced 1 top flap 2 by main terraced 1
Setting 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
Ladder 1 is connected to the outside of catch pit port by the card extension bar 3 on flanging 2, and is made main by the spring 11 on card extension bar 3 and presser feet 10
