Abstract

The utility model discloses a fast adjusting manhole cover base, which is composed of a base, an adjusting base which can adjust in a big distance, a manhole cover, cross hole fixing racks which can adjust in a small distance, a bolt block, a support block, etc., wherein, the adjusting base which can adjust in a big distance forms a support rack at an inner edge which can contain the bolt block. An adjusting screw can penetrate and be sheathed with the bolt block, and the cross hole fixing racks which can adjust in a small distance are symmetrically arranged at the bottom end of the adjusting base. Screws are used for penetrating cross holes, and the distance adjustment in the cross holes can be formed. The elevating state can be adjusted by the adjusting base of the manhole cover by the utility model to lead the manhole cover to be flat with road surfaces, and rough and cragged roads are improved.

Description

Rapid adjustment formula manhole cover ring

The utility model relates to a kind of rapid adjustment formula manhole cover ring.

Generally, road because of setting (as sewer etc.) that underground pipeline is arranged on the road surface, the setting of manhole cover is all arranged, and all fixing specification of the manhole cover of commonly using, therefore when burying manhole cover underground and desiring to flush with road, difficulty very, if especially road through repairing repeatedly after, pavement of road and manhole cover are difficult to the height that reaches consistent especially, so form raised or sunken road barricade, not only the driving vibrations are uncomfortable, severe patient, more can cause the damage of vehicle or have an accident, be a kind of very serious disappearance for traffic safety.

The purpose of this utility model is to provide a kind of rapid adjustment formula manhole cover ring, so that road is flat, steady.

For reaching above-mentioned purpose, the utility model by pedestal, have adjustment seat, the manhole cover that big distance adjusts and cross bore fixed mount, bolt piece, back-up block etc. and constitute with small distance adjustment; The seat of adjusting with the adjustment of big distance forms bracing frame in inner edge, can hold the bolt piece, adjusts screw for furnishings and wears; Cross bore fixed mount with small distance adjustment is located at an adjustment seat bottom with symmetric mode, utilizes screw to pass through cross bore, is formed on distance adjustment in the cross bore.

Wherein, adjust the seat bottom and form a ladder bottom, cooperate and hold the linkings piece on tool ladder top, top, make and adjust seat and can bear by adjusting a seat top and be subjected to the vehicle generation gravity of passing through, with the stability on maintenance manhole cover ring and road surface.

After adopting said structure, the utility model utilizes the form of the adjustment seat adjustable lifting of manhole cover, and manhole cover must be flushed with the road surface, has improved rugged and rough road.

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 6 is the sectional drawing of the utility model back-up block;

Fig. 7 is the enforcement schematic diagram that the utility model is provided with back-up block;

Fig. 8 is the illustration of implementing that the utility model is adjusted seat.

The utility model is a kind of rapid adjustment formula manhole cover ring, is made of pedestal 1, adjustment seat 2 cross bore fixed mounts 3, manhole cover 4 and back-up block 6.

See also Fig. 1-4, wherein: be a spatial accommodation in the pedestal 1, provide to hold and adjust seat 2 in interior, in being provided with near bottom place being referred to as to display hole 11, and in the outside with fixed screw 13 furnishings, pedestal 1 is stabilized in Tu Shishang, with containment vessel 12 suits, can insert native stone around pedestal 1 again; Adjust seat 2 inner edge places and form several upper and lower end bracing frames 21, this bracing frame 21 can hold bolt piece 22, and for the bottom of furnishings in the adjustment of screw fixed mount 24, preceding formation tool cross bore 32 is fixed on the furnishings hole 11 of pedestal 1 can make screw 31 pass through; Manhole cover 4 places to be adjusted on the seat 2.

By the aforementioned structure element, the utility model is the form of the big distance of narration adjustment earlier, consult Fig. 1,2, owing to adjust seat 2 inner edges several bracing frames 21 are arranged, when therefore desire is adjusted bolt piece 22 is held, and wear to adjust screw 23, utilize this moment a pneumatic sleeve will adjust screw 23 rotations, can successfully will adjust seat 2 rises or descends, therefore, when stone 5 drops are big on pedestal 1 furnishings position and the road, can utilize and adjust after screw 23 is adjusted this adjustment 2 and the road surface is concordant, put manhole cover 4 again and get final product, this mode is to adopt big distance to adjust.

And the utility model is also implemented with another form, as shown in Figure 5, promptly be the mode of row small distance adjustment, utilization is set up cross bore fixed mount 3 in place, adjustment seat 2 a bottoms symmetry, utilizes screw 31 displayying in the hole 11 through cross bore 32 furnishings, adjust seat 2 to support, this moment is because cross bore fixed mount 3 adopts the slotted eye of crosss, thus adjust apart from the time, all be limited in this cross bore 32, must often open operation so form can be used in manhole cover 4, thus with the road surface drop be not very big situation.

See also Fig. 6,7 again, back-up block 6 is for placing the element of adjusting seat 2 bottoms, and the top forms ladder top 61, can be engaged in the ladder bottom 25 of adjusting seat 2 bottoms.

This back-up block 6 is because the top is ladder top 61, when making in placing adjustment seat 2 ladder bottoms 25, with the ladder tabling, order is adjusted seat 2 and is not had above back-up block 6 and produce displacement or built on the sand, simultaneously, after back-up block 6 is inserted the location, bear the gravity of vehicle dealing because of adjusting seat 2 and manhole cover 4 end faces, therefore after inserting back-up block 6, can support fully adjusting seat 2, to bear the suffered intensity of gravity of end face fully, with the stationarity on increase manhole cover ring and road surface, and the situation of no one's port lid seat depression drop takes place.

See also Fig. 8 for adjusting another embodiment of seat 2, adjust seat 2 and form device and be applicable to that special road conditions (example: tilt or the road surface of the tool gradient) make and adjust the seat 2 more appropriate pavement behaviors of joining, and reach smooth fully with the road surface with gradient.

Because the utility model system is at producing drop with pavement behavior, and has the adjustment form on big distance and small distance and slope, kept the concordant of manhole cover ring and road surface, and back-up block setting with the weight of bearing, not only has practical improvement, more make road reach smooth stable state, to ensure people's safety of driving a vehicle.
