The portable cable trench cover opening device of this structure, when in use, by the hook at clamping bar two ends according to cable
The size regulation of trench cover is then snapped on cable channel cover plate to corresponding position, and the distance of two hooks is adjusted again, clamps electricity
Cable trench cover, starts Horizontal jack, moves stand type support relative level support, so that drive clamping bar to move upwards,
Clamping bar drives cable channel cover plate to move upwards again, departs from cable duct, and that side horizontal stand that then will be close to human body is improved, to
It is preceding to promote whole portable cable trench cover opening device, so that it may cable channel cover plate to be taken away into cable duct, after inspection is finished, equally
Opening device is moved to the position of cable channel cover plate for the side for lifting horizontal stand, loosens Horizontal jack, realizes cable operculum colpi
The reset of plate.
Described telescopic clamping bar is by positioned at middle big sleeve pipe and the small casing structure positioned at big cannula cavity two ends
Into, its axis direction is provided with rows of through hole on small casing, through hole is respectively arranged with the both ends of big sleeve pipe, big set
Pipe is fixed with the through hole latch or threaded connector of small casing, and one of hook is set directly on small casing,
Another hook is then arranged on small casing by movable folder, and insertion small casing radial direction is offered in the end of the small casing
Groove, groove is provided with inner nut along the axially extending of small casing in the outer end of small casing groove, is set in small casing inner chamber
The screw rod that can be matched with the inner nut on small casing is equipped with, described screw rod is connected with movable folder and transported with drive activity folder
It is dynamic.
The telescopic clamping bar of this structure, can be previously according on the size of the cable channel cover plate regulation telescopic clamping bar of coarse adjustment two
The distance between hook, the specific method of its coarse adjustment is to adjust small casing then to use latch relative to the big position waited between sleeve pipe
Or threaded connector is locked, to lock the position of small casing, then again fine tuning screw rod end that hook, fine tuning it is specific
To rotate screw rod, the screw rod of rotation rotates and produces axial movement method with respect to the inner nut of small casing, thus drive with
Its connected movable folder is moved axially, and movable folder drives hook to be moved again, so as to realize the fine setting of the hook,
Realize clamping of the whole device to cable operculum colpi.
Described movable folder is provided with locating rod to be sleeved on small casing on movable folder, and this bar is by activity
The side of folder penetrates, and penetrates the groove of small casing, is passed by the opposite side of groove again after being connected with screw rod, is then passed through activity
The opposite side of folder.
Screw rod is that through hole is provided with locating rod with the connection of locating rod, after screw rod passes through the through hole, keeper lock
Tightly.
Handle is additionally provided with horizontal stand.
In sum, present invention advantage following compared to existing technology：
Portable cable trench cover opening device of the invention, is capable of the cable channel cover plate of suitable for various size, can reduce
Configuration quantity, it is cost-effective.Because this set opening device uses screw rod clamping device, the edge of cover plate can be firmly clamped,
