Referring to fig. 2 and 3, two supporting cross rods 44 are arranged in the inspection well body 1, the two supporting cross rods 44 are positioned below the ring support 3, and the two supporting cross rods 44 are positioned on the same horizontal plane and are arranged in parallel. One end of each of the two supporting cross rods 44 is hinged on the inner wall of the inspection well body 1, a warning board 45 is arranged between the two supporting cross rods 44, and a reflective belt 451 is arranged on the side wall of the warning board 45. The inspection well body 1 is internally provided with a first fixing piece 7 which is used for fixing the supporting cross rod 44 when the supporting cross rod 44 is in a horizontal state, the first fixing piece 7 comprises a U-shaped clamping groove 71 and a tightening bolt 72, the U-shaped clamping groove 71 is fixedly arranged on the inner wall of the inspection well body 1, the side wall of the U-shaped clamping groove 71 is provided with a threaded opening 711, and one end of the tightening bolt 72 is in threaded connection with the threaded opening 711.
If need hold in the palm 3 upper cover at the ring when closing well lid 2, operating personnel rotates a support horizontal pole 44 and makes it be in the horizontality after, places the one end that supports horizontal pole 44 in U-shaped draw-in groove 71, and operating personnel rotates again and supports tight bolt 72 for support the one end of tight bolt 72 and the lateral wall butt of supporting horizontal pole 44, will support horizontal pole 44 to fix at the horizontality, operating personnel closes well lid 2 lid again on ring holds in the palm 3 can.
Referring to fig. 4 and 6, a second fixing member 8 for fixing the supporting cross rod 44 when the supporting cross rod 44 is in a vertical state is further arranged in the inspection well body 1, the second fixing member 8 includes a first connecting transverse plate 81, a second connecting transverse plate 82 and a first connecting bolt 83, the first connecting transverse plate 81 is fixedly arranged on the side wall of one supporting cross rod 44, the second connecting transverse plate 82 is fixedly arranged on the inner wall of the inspection well body 1, connecting openings for the second connecting bolt 52 to pass through are respectively formed in the first connecting transverse plate 81 and the second connecting transverse plate 82, and a movable nut 831 is further connected to one end of the first connecting bolt 83 through a thread.
When the manhole cover 2 is lost or an operator needs to overhaul the manhole body 1, the operator rotates one cross rod to enable the cross rod to be in the vertical state, then the first connecting bolt 83 penetrates through the connecting openings in the first connecting transverse plate 81 and the second connecting transverse plate 82, and then the movable nut 831 is screwed on the first connecting bolt 83, so that the supporting cross rod 44 is fixed in the vertical state.
The implementation principle of the embodiment is as follows: before using this inspection shaft, operating personnel rotate earlier and support horizontal pole 44 and make it be in vertical state, pass the connection opening on first connecting transverse plate 81 and the second connecting transverse plate 82 with first connecting bolt 83, then with activity nut 831 threaded connection to first connecting bolt 83 to fixed support horizontal pole 44 reminds pedestrian and vehicle through warning board 45 between two support horizontal poles 44. The operator connects the four second connecting bolts 52 penetrating through the outer protective ring plate 41 with the four internal threaded sleeves 51 on the inner wall of the inspection well body 1. Then the supporting cross rod 44 is rotated to be in a horizontal state, the supporting cross rod 44 is fixed through the first fixing piece 7, the manhole cover 2 is covered on the manhole body 1, and the manhole can be put into use. Under the condition that well lid 2 damaged or lost, operating personnel rotated support horizontal pole 44 and made it be in vertical state, placed the one end of supporting horizontal pole 44 in U-shaped draw-in groove 71, operating personnel rotated tight bolt 72 again for the one end of tight bolt 72 and the lateral wall butt of supporting horizontal pole 44. If there is the pedestrian to drop to the inspection shaft body 1 in, the supporting network 43 plays the supporting role to the pedestrian, and the pedestrian produces the impact force to the supporting network 43 for second sleeve 62 slides along the direction of keeping away from first sleeve 61, makes buffer spring 63 take place deformation simultaneously, and some impact force are offset to the elasticity that buffer spring 63 produced, thereby reduces pedestrian's potential safety hazard.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
