Topic, the utility model provides a kind of flexible manhole cover lifting device, using following technical proposals：
A kind of flexibility manhole cover lifting device, including：Door shape holder, punching jack hydraulic device, pull rod, cross
The drag hook of steelframe and 4 L-types；
Wherein, the punching jack hydraulic device include be arranged door shape rack beam centre position jack and
Drive the hydraulic device of jack；
The elevating lever of the pull rod across jack center and door shape rack beam, upper end and jack, which is fixed, to be connected
It connects, the universal ball seat of the lower end with bulb and cross steelframe center is connected；
Each endpoint of cross steelframe is hinged with drag hook；
The safe lock fork of anti-locking hook is provided on the drag hook.
Preferably, the drag hook lower end is duck-beak type right angle hook；The drag hook lower end is duck-beak type right angle hook；The safety
Lock fork, on the handle of drag hook, well lid to be onstructed is adjacent to by spring tension or gravity with axis connection.
Further, the long 1200mm of door shape rack beam, crossbeam centre position is reinforced and is set using steel plate
Set a circular hole；High 100 mm of the high 700mm of supporting leg, feet；Rod length is 500mm；Cross steelframe length 700mm；Drag hook length
For 300mm, safe lock fork is set at duck-beak type right angle hook 120mm.
The utility model has the following advantages that：
（1）It is promoted by cross steelframe and 4 drag hooks, makes the uniform force of manhole cover；
（2）Pull rod and stress cross steelframe junction, use universal ball joint, in the fast lifting construction of manhole cover,
Stress point angle can constantly be automatically adjusted, stress frame and manhole cover can be made to remain parallel steady raising, four direction by
Dynamic balance；
（3）It is quickly jacked up using jack, it is efficient, lift is big, process is steady；
（4）In preferred embodiment safe lock fork is respectively provided on four drag hooks；In working condition, safe lock fork is pressed in
Above manhole cover, the effect clamped down on is formd to inspection shaft with drag hook, so that manhole cover is promoted not easily to fall off, the course of work is made to pacify
Full property higher.
Description of the drawings
Fig. 1 is the embodiments of the present invention structural schematic diagram；
Wherein：1 door shape holder, 2 pull rods, 3 jack, 4 universal ball joints, 5 cross steelframes, 6 drag hooks, 7 safe lock forks,
8 hydraulic devices.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, the present embodiment is a kind of flexible manhole cover lifting device, including：Door shape holder 1, punching thousand
The drag hook of jin top hydraulic device, pull rod 2, cross steelframe 5 and 4 L-types；
Wherein, the punching jack hydraulic device includes the jack 3 being arranged in door shape rack beam centre position
With the hydraulic device 8 of driving jack；
Across the pull rod 2 of 1 crossbeam of 3 center of jack and door shape holder, upper end and the elevating lever of jack 3 are fixed
The universal ball seat of connection, 5 intermediate intersection of the lower end with bulb and cross steelframe is connected；
5 each endpoint of the cross steelframe is hinged with drag hook 6.
1 crossbeam length of the door shape holder is 1200mm, and the high 700mm of supporting leg, crossbeam centre position is carried out using steel plate
A circular hole is reinforced and is arranged, crossbeam total height is 800mm（High 100 mm of feet, long 300 mm, is stablized with more preferable holding）, pull rod
2 length are 500mm, and the every beam length 700mm of cross steelframe 5, drag hook length is 300mm.
The jack 3 is connect by two oil pipes with pressue device using 2000Kg punchings top；Hydraulic device can control
Jack 3 steadily lifts, moreover it is possible to observed pressure data.
