Specific embodiment
The embodiment of the utility model anti-stealing manhole cover is described further referring to figs. 1 to Fig. 4.
A kind of anti-stealing manhole cover including removable cover 2 and pedestal 1, is provided between the removable cover 2 and pedestal 1 and waves
Connecting rod 7,7 both ends of yaw link are hinged with removable cover 2 and pedestal 1 respectively, and sliding slot 3 is provided on the pedestal 1, described
Sliding block 4 is provided in sliding slot 3, jacking connecting rod 5,5 both ends of the jacking connecting rod are provided between the removable cover 2 and sliding block 4
It is hinged respectively at removable cover 2 and sliding block 4, limit pull rod 6 is hinged between the jacking connecting rod 5 and pedestal 1, the limiting is drawn
Bar 6 is provided with lifting body, the pedestal 1 between sliding slot 3 and yaw link 7 between the removable cover 2 and pedestal 1
Opening 12 is provided with, the yaw link 7, jacking connecting rod 5 and limit pull rod 6 are respectively positioned on 12 inside of opening, the removable cover 2
There are cover in the space being open on 12 edges at edge.
Preferably the removable cover 2 and pedestal 1 are rectangle to the present embodiment, the yaw link 7, sliding slot 3, sliding block 4,
There are two jacking connecting rod 5 and limit pull rod 6 are respectively provided with, and it is located at two opposite medial surfaces of pedestal 1, the lifting body respectively
Including jacking hydraulic cylinder 8 and supporting rack 9, the both ends of the jacking hydraulic cylinder 8 are hinged respectively at removable cover 2 and supporting rack 9.
As shown in Figure 2 and Figure 4, yaw link 7 is located at the right side of entire well lid, and yaw link 7 is hinged with removable cover 2
The edge of place and removable cover 2 still has a distance, this reserved space is to ensure the opening that cover board can be covered completely in pedestal 1
At 12, the length of yaw link 7 is less than the length of jacking connecting rod 5.
When opening, the piston elongation of hydraulic cylinder 8, the right side of yaw link 7 is swung up, while is jacked connecting rod 5 and driven
