Detailed Description

The present application is described in further detail below with reference to the attached drawings.

In this embodiment: an inspection well, referring to fig. 1, comprising: well circle 1 and connect in the well lid 2 at 1 top of well circle, 1 internal fixedly connected with of well circle two first branches 3 that are used for supporting well lid 2, two first branches 3 parallel, sliding connection has two-purpose second branch 4 that is used for supporting well lid 2 between two first branches 3, and two second branches 4 parallel, offer on the first branch 3 and supply the gliding spout of second branch 4, are equipped with the adjustment mechanism who is used for adjusting 4 positions of second branch on the first branch 3.

When installation well lid 2, adjust two second branch 4 to walling crib 1 middle part through adjustment mechanism, two first branches 3 support well lid 2 simultaneously with two second branches 4, have shared the pressure that well lid 2 applyed 1 to walling crib, make 1 atress of walling crib more even, have reduced the damaged possibility of walling crib 1 appearance.

In addition, 4 top welding of second branch has extension board 41, and the benefit that sets up like this lies in, has increased the area of contact between second branch 4 and the well lid 2, has promoted the supporting effect, and during the maintenance, through adjustment mechanism with two second branches 4 to 1 both sides of walling crib, the staff of being convenient for gets into in the well, and the practicality is strong.

It should be noted that well lid 2 is T shape, and step 11 that is used for accepting well lid 2 is offered at 1 top of walling crib, and the benefit that sets up like this lies in, has increased well lid 2 and walling crib 1's area of contact, and the atress of walling crib 1 is more even, has further reduced the impaired possibility of walling crib 1.

Wherein, adjustment mechanism includes power component and fixed subassembly, and power component includes to rotate to be connected in the double threaded screw 31 of 3 one sides of arbitrary first branch, and the welding has the spacing ring 51 that is used for restricting double threaded screw 31 on the lateral wall of first branch 3, and double threaded screw 31 both ends respectively with two 4 threaded connection of second branch.

Wherein, fixed subassembly includes nut 32 of threaded connection in double-end screw 31 both ends respectively, and nut 32 one side butt is on second branch 4, and in addition, the cover is equipped with gasket 52 on the double-end screw 31, and gasket 52 is located between nut 32 and the second branch 4.

When adjusting the position of two second branch 4, rotate double-end screw 31, double-end screw 31 drives two second branch 4 simultaneously and is close to mutually or keeps away from mutually, adjusts two second branch 4 to predetermined position after, revolves two nuts 32 respectively to double-end screw 31 both ends, until nut 32 butt on second branch 4, double-end screw 31 is fixed, and it is convenient to adjust, and is fixed firm.

Wherein, the welding has two symmetrical locating pieces 21 on the lateral wall of well lid 2, sets up two symmetrical constant head tanks 22 that are used for accepting locating piece 21 on the walling crib 1, and locating piece 21 passes through bolt 23 and connects on walling crib 1, and the countersunk head groove 53 that is used for holding nut on bolt 23 is seted up at locating piece 21 top.

When installation well lid 2, put into the locating slot 22 on the walling crib 1 with locating piece 21 on the well lid 2, again with bolt 23 screw in locating piece 21 and walling crib 1 simultaneously, the nut gets into countersunk head groove 53, well lid 2 is fixed, when the car rolls well lid 2, well lid 2 can vibrate thereupon, through locating piece 21 and locating slot 22's setting, radially carry on spacingly to well lid 2, the possibility of well lid 2 vibration has been reduced, the not hard up possibility of bolt 23 has been reduced.

In addition, the bottom of the nut on the bolt 23 is annularly provided with a plurality of elastic lugs 24, the elastic lugs 24 are rubber blocks, the number of the elastic lugs 24 can be 4, and the top of the positioning block 21 is provided with a containing groove 25 for containing the elastic lugs 24.

After the bolt 23 is screwed into the positioning block 21, the elastic lug 24 on the nut enters the accommodating groove 25 to limit the bolt 23 in the radial direction, so that the possibility of loosening the bolt 23 is further reduced.

Well lid 2 is in for a long time under the state that is rolled, and bolt 23 still has not hard up possibility, consequently, in this embodiment, the outside of well lid 2 all is equipped with buffer layer 12 with the inboard of walling crib 1, and buffer layer 12 is the rubber pad, and when well lid 2 rocked, buffer layer 12 played the cushioning effect, has slowed down the striking between well lid 2 and the walling crib 1, has further reduced the impaired possibility of walling crib 1.

The implementation principle of this application embodiment inspection shaft does: when the well lid 2 is installed, the double-threaded screw 31 is rotated, the double-threaded screw 31 simultaneously drives the two second support rods 4 to slide towards the middle of the well ring 1, then the two nuts 32 are respectively screwed into the two ends of the double-threaded screw 31 until the nuts 32 abut against the second support rods 4, and the double-threaded screw 31 is fixed.

Then put into the constant head tank 22 on the walling crib 1 with locating piece 21 on the manhole cover 2, step 11 on the walling crib 1 holds the manhole cover 2, the buffer layer 12 in the manhole cover 2 outside offsets tightly with the buffer layer 12 of walling crib 1 inboard, screw in locating piece 21 and walling crib 1 simultaneously with bolt 23, the elasticity lug 24 on the nut gets into in the holding tank 25, the manhole cover 2 is fixed, extension board 41 supports the manhole cover 2 with first branch pole 3 simultaneously, the pressure that the manhole cover 2 was applyed to walling crib 1 has been shared, make the atress of walling crib 1 more even, the impaired possibility of walling crib 1 has been reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
