The portable cable trench cover opening device of this structure, in use, the hook at clamping bar two ends is adjusted to corresponding position according to the size of cable channel cover plate, then snap on cable channel cover plate, again adjust the distance of two hooks, clamping cables trench cover, start Horizontal jack, stand type support relative level support is moved, thus drive clamping bar to move upward, clamping bar drives again cable channel cover plate to move upward, depart from cable trough, then that side horizontal stand near human body is improved, driven forward whole portable cable trench cover opening device, just cable channel cover plate can be taken away cable trough, after inspection, opening device is moved to the position of cable channel cover plate by the side of mentioning horizontal stand equally, loosen Horizontal jack, realize the reset of cable channel cover plate.
Described telescopic clamping bar is be made up of the small casing being positioned at middle large sleeve pipe and being positioned at large cannula cavity two ends, small casing is provided with through hole in a row along its axis direction, through hole is respectively arranged with at the both ends of large sleeve pipe, the through hole latch of large sleeve pipe and small casing or threaded connector are fixed, one of them hook is set directly on small casing, another hook is then arranged on small casing by movable folder, the groove of through small casing radial direction is had at the end opens of this small casing, groove extends along the axis of small casing, the outer end of small casing groove is provided with inner nut, the screw rod that can match with the inner nut on small casing is provided with at small casing inner chamber, described screw rod is connected with movable folder to drive movable folder to move.
The telescopic clamping bar of this structure, the distance on the telescopic clamping bar of coarse adjustment between two hooks can be regulated in advance according to the size of cable channel cover plate, the concrete grammar of its coarse adjustment is regulate small casing to wait the position between sleeve pipe then to lock with latch or threaded connector relative to large, to lock the position of small casing, then again fine tuning screw rod end that hook, the concrete grammar of fine tuning is rotating screw bolt, the inner nut of the relative small casing of screw rod rotated rotates and produces and moves axially, thus drive coupled movable folder to move axially, movable folder drives again hook to be moved, thus realize the fine setting of this hook, realize the clamping of whole device to cable operculum colpi.
Described movable folder is for being sleeved on small casing, movable folder is provided with backstay, and this bar is penetrated by the side of movable folder, penetrates the groove of small casing, passed by the opposite side of groove again after being connected with screw rod, then pass the opposite side of movable folder.
The connection of screw rod and backstay is that place is provided with through hole at backstay, and screw rod is through after this through hole, and keeper is locked.
Horizontal stand is also provided with handle.
In sum, the utility model following advantage compared to existing technology:
Portable cable trench cover opening device of the present utility model, can the cable channel cover plate of suitable for various size, can reduce configuration quantity, cost-saving.Because this cover opening device adopts screw rod clamping device, the edge of cover plate can be clamped firmly, be convenient to lifting.This opening device utilizes hydraulic jack to realize slinging of cover plate, easy and simple to handle, laborsaving, safe and reliable; This opening device is provided with four wheels, is convenient to remove after slinging in lid limit, and moves like a cork.This opening device can be disassembled into several widget, and can rapid-assembling, is easy to carry.
