After playing cable well lid, it is simple to fixing of cable well lid, save manpower.
Further, described hook is arranged on lever by lifting screw mandrel, and described hook is playing hang spring by screw thread switching
On bar, described lifting screw mandrel is transferred on lever by bearing pin；It is conveniently adjusted the distance hooking into ground, to adapt to different feelings
Condition.
Compared with prior art the invention have the advantage that in the present invention and be provided with door frame and lever, by the principle of lever,
When opening cable well lid, manpower can be saved, and can ensure that the safety of staff；After hook triggers cable well lid,
It is easy to be removed by cable well lid and reset by wheel and guide rail.
Accompanying drawing explanation
The invention will be further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of embodiment one in the present invention；
Fig. 2 is the structural representation of embodiment two in the present invention.
Detailed description of the invention
Embodiment one:
Refering to Fig. 1, a kind of cable manhole cover hoisting device, is parallel to each other including door frame 1, two and fore-and-aft direction is arranged leads
The wheel 3 that 4, four, rail is separately positioned on four angles of door frame 1 and is arranged in two guide rails 4, the thick stick transferred on door frame 1
Bar 2, it is arranged on lever 2 one end and for catching on the hook 5 of cable well lid.Described lever 2 is arranged by a left and right directions and turns
The rotation bar 21 being connected on door frame 1,22, two, the handle being connected in the middle part of rotation bar 21 and be perpendicular to rotate bar 21 are respectively fixedly connected with
Rotate bar about 21 two ends and be perpendicular to rotate bar 21 pole 23 constitute, described hook 5 has two and transfers respectively two
On root pole 23.Described handle 22 is connected in, by two, the quarter butt 221, two rotated on bar 21 and is socketed in two quarter butts respectively
Long tube 222 on 221 is constituted.It is threaded connection between described long tube 222 and quarter butt 221.Described rotation bar about 21 is often held
All and it is provided with bearing 6 between door frame 1.Described door frame 1 is provided with bracing piece 7.Draw-in groove 8, described draw-in groove it is fixed with on described lever 2
On 8, switching has the drag hook 9 for catching on bracing piece 7.Described hook 5 is arranged on lever 2 by lifting screw mandrel 13, described hook
5 are lifting by crane on screw mandrel 13 by screw thread switching, and described lifting screw mandrel 13 is transferred on lever 2 by bearing pin.
During use, two guide rails 4 are separately fixed at the left and right sides of cable well lid, make the wheel 3 of door frame 1 enter accordingly
Guide rail 4 in；Regulation lifting screw mandrel 13, makes two handles that two hooks 5 catch on cable shaft lid respectively；By two root length pipes
