Description
Technical field
The present invention relates to municipal works field more particularly to a kind of catch pit port cat ladders.
Background technology
A lot of 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 will be there are one the outlets for leading to ground, by pipeline to ground every one section
This section is known as inspection shaft, and catch pit port is usually concordant with ground, it is therefore desirable to which a lid for the lid of lid inspection shaft, is inspection shaft
Lid.Inspection well cover is usually made of materials such as reinforced concrete, metal, reinforced plastics, and shape is based on round and rectangular.
Under normal conditions, it is all closed on catch pit port with inspection well cover, prevents pedestrian from falling into, ensure safety.During construction, apply
Worker person can erect warning rail in catch pit port surrounding, then remove inspection well cover and construct.
But it is of different sizes due to underground piping, the distance between inspection well cover and underground piping are also different, are
Facilitate above and below construction personnel, some catch pit ports have just set cat ladder at the initial stage of construction, but this construction cost compares
Height, therefore, most of catch pit port will not pre-install cat ladder, and construction personnel is when construction mostly using above and below rope ladder.Rope ladder
Softer although being convenient for carrying, when use, easily shakes, inconvenient.
Invention content
Facilitate construction personnel and the good catch pit port of stability is climbed the technical problem to be solved by the invention is to provide a kind of
Ladder.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of catch pit port cat ladder, tool
There is main ladder, the top of the main ladder is provided with flanging, and bottom part down is connected with extension ladder, and the top of the extension ladder is provided with extension
Hook, extension ladder is by being hung on main ladder；The end set of the flanging has clamping bar, the both ends extension of the clamping bar
Outside the both sides of flanging, which is provided with symmetrical slow pressure device；The slow pressure device is by spring and presser feet
It forms, top and the clamping bar of the spring weld admittedly, and the top of bottom and presser feet is welded admittedly；It is fixedly installed at the top of the presser feet
Lower limit guide rod is fixedly installed upper limit guide rod, the upper limit guide rod and lower limit guide rod on corresponding clamping bar
It is symmetrical above and below, spacing is provided between the plane of symmetry, the spring is wrapped in the outside of upper limit guide rod and lower limit guide rod.
Preferably, the two bottom sides of the main ladder and extension ladder are respectively provided with, there are two symmetrical compression bars, described
Compression bar is in homonymy with flanging, corresponding up and down.
Preferably, the compression bar is connected by being welded in the support connector of the terraced two bottom sides of main ladder and extension admittedly；The support
The end of connector is in " ∪ " type, and one end of the compression bar is located in support connector, is connected between support connector by axis pin activity
It connects.
Preferably, the other end that the compression bar corresponds to support connector is provided with feet, between the feet and compression bar
Logical ball cup flexible connection.
Compared with prior art, the invention has the beneficial effects that：This catch pit port cat ladder is simple in structure, and top is clamped
Outside catch pit port, lower section is supported by compression bar, and stability is good, facilitates above and below construction personnel, and can be according to the height of inspection shaft
Degree increases cat ladder length, adaptable.

Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and detailed description.
A kind of catch pit port cat ladder shown in Fig. 1 and Fig. 2 has main terraced 1, and main terraced 1 top is provided with flanging 2, bottom
Lower section is connected with extension ladder 4, and the top of the extension ladder 4 is provided with hook 9, and extension ladder 4 is hung on by hook 9 on main terraced 1；
The end set of the flanging 2 has clamping bar 3, and the both ends of the clamping bar 3 are extended in outside the both sides of flanging 2, the both ends bottom
Portion is provided with symmetrical slow pressure device；As shown in figure 3, the slow pressure device is made of spring 11 and presser feet 10, the bullet
The top of spring 11 is welded admittedly with clamping bar 3, and bottom and the top of presser feet 10 are welded admittedly；The top of the presser feet 10 is fixedly installed lower limit
Position guide rod 13, is fixedly installed upper limit guide rod 12 on corresponding clamping bar 3, the upper limit guide rod 12 and lower limit are led
Bar 13 is symmetrical above and below, and spacing is provided between the plane of symmetry, and the spring 11 is wrapped in upper limit guide rod 12 and lower limit guide rod
13 outside.In order to which there is spacing with inspection shaft road behind main terraced 1 and 4 installation of extension ladder, facilitate construction personnel up and down and improve steady
It is qualitative, described main terraced 1 and the two bottom sides of extension ladder 4 be respectively provided with there are two symmetrical compression bar 5, the compression bar 5 with
Flanging 2 is in homonymy, corresponding up and down.Compression bar 5 is converted into for convenience, the compression bar 5 by being welded in main terraced 1 He admittedly
The support connector 6 of terraced 4 two bottom sides of extension connects；In " ∪ " type, one end of the compression bar 5 is located at for the end of the support connector 6
It holds in the palm in connector 6, is flexibly connected between support connector 6 by axis pin 7, the compression bar 5 corresponds to the other end setting of support connector 6
There is feet 8, ball cup is led between the feet 8 and compression bar 5 and is flexibly connected, can realize the tight of feet 8 and inspection shaft road wall surface
Closely connected conjunction, make main terraced 1 and extension ladder it is 4 more firm.
In use, the inspection well cover on catch pit port is removed, then main terraced 1 is put into catch pit port, main terraced 1 top flap 2
Setting can make main terraced 1 with the wall surface distance in inspection shaft road closer to main so as to increase the disengaging area of construction personnel on catch pit port
Ladder 1 is connected to the outside of catch pit port by the clamping bar 3 on flanging 2, and passes through the spring 11 being clamped on bar 3 and presser feet 10 and make master
There is slow pressure between ladder 1 and ground, avoid contacting firmly and caused by vibration；Compression bar 5 on main terraced 1 bottom support connector 6 is put
Under, the feet 8 of 5 end of compression bar is made to withstand inspection shaft road wall surface, feet 8 is connect by ball cup with compression bar 5, can make feet
Adapt to the inspection shaft road wall surface of different angle, make it is main it is terraced 1 it is more stable while, make main terraced 1 to keep a spacing with inspection shaft road wall surface
From, avoid because patch it is too near due to inconvenient construction personnel above and below；If the height in inspection shaft road is higher, can successively be hung under main terraced 1
The extension ladder 4 for adapting to quantity is put, and extend ladder 4 makes it keep certain with inspection shaft road wall surface by the compression bar 5 of its bottom simultaneously
Distance and improve its stability, can be realized above and below construction personnel after installation is complete.
This catch pit port cat ladder is simple in structure, and top is connected to outside catch pit port, and lower section is supported by compression bar 5, surely
It is qualitative good, facilitate above and below construction personnel, and cat ladder length can be increased according to the height of inspection shaft, it is adaptable.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made in any form
Limitation, any simple modification, equivalent change and modification that every technical spirit according to the present invention makees above example,
In the range of still falling within technical solution of the present invention.
