Contracting formula anti-fall device.
Background technique
Can all it be arranged every a distance for overhauling along high-tension cable channel 2, the cable manhole of O&M and emergency etc.
The well head of well 1, cable manhole well 1 is square, and the well head of cable manhole well 1 is protected using all kinds of well lids 6 (such as Fig. 1 institute
Show), its axial direction is provided with several staircases 4 on the inner wall of cable manhole well 1；It is past below the well head of cable manhole well 1
It is past to be provided with the falling proof devices such as fixed anti-drop net 5 as required.As depicted in figs. 1 and 2, falling proof device generallys use steel at present
One end of the fixation anti-drop net 5 that muscle is formed by connecting, fixed anti-drop net 5 is flexibly connected, and other end locking is fixed.Operating personnel
When being worked in into cable manhole well 1, need to rotate the fixed anti-drop net 5 of unlatching upwards.
Above-mentioned fixed anti-drop net there is a problem of following during use:
1, during being rotated up unlatching fixation anti-drop net, between fixed anti-drop net and the well head of cable manhole well
Distance has to be larger than the length of fixed anti-drop net, otherwise can not fully open fixed anti-drop net, leads to that there are certain safety is hidden
Suffer from；
2, fixed anti-drop net is caused operating personnel to open in entering cable manhole well and is fixed using opening ways upward
When anti-drop net, the unlatching of fixed anti-drop net is inconvenient；
3, in order to be observed to the situation inside cable manhole well, monitoring can be installed on the inner wall of cable manhole well
It is typically mounted at the top of fixed anti-drop net with auxiliary devices, these auxiliary devices such as blowers, in order to avoid auxiliary device is to solid
The unlatching for determining anti-drop net impacts, and need to further increase the distance between the well head of fixed anti-drop net Yu cable manhole well, and
Fixed the distance between anti-drop net and the well head of cable manhole well are bigger, when there is object to fall to rushing of generating on fixed anti-drop net
Amount is bigger, and the impact force that fixed anti-drop net is subject to is bigger, so as to shorten the service life of fixed anti-drop net.
Utility model content
For the deficiency in the presence of the prior art, the purpose of this utility model is to provide one kind for being arranged in cable
Telescopic anti-fall device in manhole well, to solve in the prior art, it is inconvenient that anti-drop net is opened, anti-drop net and cable manhole well
The big problem of the impact force that the distance between well head is big and its distance causes greatly anti-drop net to be subject to.
To achieve the above object, the utility model uses the following technical solution: for being arranged in cable manhole well
Telescopic anti-fall device, including cable manhole well is provided in the cable manhole well and to be opened using horizontal extension mode
Telescopic anti-drop net, one end of telescopic anti-drop net and the inner wall of cable manhole well are rotatedly connected, telescopic anti-drop net it is another
End is fixedly connected by multiple detachable locking members with the inner wall of cable manhole well.
Compared with the prior art, the utility model has the following beneficial effects:
1, by the design of telescopic anti-drop net, so that telescopic anti-drop net is adopted when opening telescopic anti-drop net
Opened with the mode moved horizontally so that operating personnel into and out of cable manhole well overhaul etc. work when
It waits, facilitates and open telescopic anti-drop net, avoid because of telescopic anti-drop net opening process bring security risk；
2, telescopic anti-drop net is opened by the way of moving horizontally, and shortens telescopic anti-drop net and cable
The distance between well head of manhole well, it is only necessary to which the space of the auxiliary devices such as reserved installation monitoring and blower, auxiliary device is not
The unlatching of telescopic anti-drop net can be impacted, and the contracting of the distance between well head of telescopic anti-drop net and cable manhole well
Short, when so that object is fallen on telescopic anti-drop net, speed is small, reduces rushing when object is contacted with telescopic anti-drop net
Amount, substantially reduces the impact force that telescopic anti-drop net is subject to, extends the service life of telescopic anti-drop net.
