Abstract

The utility model discloses a lifting well cover support which is composed of an upper support body capable of lifting and a fixed lower support body, wherein the upper support body and the lower support body are combined in a supporting and inserting mode, sealed by a rubber pad and connected through a screw in the axial direction so that the function of lifting can be achieved. The technology that a bolt is connected with a wedge body is adopted in the radial direction so that the upper support body is firmly combined with the lower support body after being lifted. Height difference between the upper surface of a well cover board and a road face can be eliminated through the lifting adjustment of the upper support body, comfort of road face driving is regained, damage to the road face around a well opening is reduced, and repairing cost of a road is decreased.

Description

A kind of lift manhole lid bearing

Affiliated technical field

The utility model relates to the screw rod lifting, and the bolton technology is specifically related to a kind of lift manhole lid bearing that adopts bolt to connect the contract body technique.

Background technology

At present, various well lid bearings on the traffic route are in installation, particularly in the use, major part all is uncontrollable, and small part adopts screw rod lifting and stressed support or adopts lifting technologies such as cylinder, gear lifting, but that these technology often are faced with reliability is not high, the structure relative complex, the scope of application is wideless, and problems such as manufacturing cost costliness have influenced the popularization of its use.

Summary of the invention

At the existing above-mentioned deficiency of existing well lid bearing technology, the utility model provides a kind of lift manhole lid bearing, and this lift manhole lid bearing has simple in structure, easy to operate, reliability height, low cost of manufacture, advantage such as applied widely.

The technical scheme that the utility model technical solution problem is adopted is: lifting support mainly is divided into liftable upper bracket and fixing undersetting two parts, last undersetting is by the combination of socket joint position, and by rubber seal, connect by screw rod at axial direction, radial direction is by bolton.When bolt unclamped, rotary screw can make the relative undersetting of upper bracket raise or reduce; After upper bracket was elevated to the target location, tighting a bolt made that undersetting is firm to combine, and finishes the lift adjustment to upper bracket.

The beneficial effects of the utility model are to carry out descending operation to upper bracket simply and easily; Only adopt bolt and screw rod can reach the function of firm lifting, simple in structure, so low cost of manufacture; Adopt bolt to connect the contract body technique, stressed effect is outstanding, and the reliability height is applicable to road in the sub-district, city ordinary road, also is applicable to vehicle flowrate is big, the load-carrying grade is high primary and secondary arterial highway, city and integrated mill's on-site road, and is applied widely.

The specific embodiment

In Fig. 1～5, in the screw hole (22) of undersetting (2), screw in lifting screw (4), place rubber pad (3) in the above, again upper bracket (1) is inserted in the undersetting (2), put into and the firm nut of spot welding (41) in lifting screw (3) upper end, bolt hole (23) in undersetting groove (21) screws in bolt (5) to correct position, be sidelong horizontalization pad (52) and fastening nut (51) outside, the bolt (5) in upper bracket tongue (11) is gone up and is placed contract type pad (54) and fastening nut (53).

Described screw rod (4), nut (41) and jacking piece (42) are connected as a single entity, clip upper bracket (1) between nut (41) and the jacking piece (42), swivel nut (41) drives screw rod (4), jacking piece (42) rotates simultaneously, screw rod (4) drives jacking piece (42) jacking upper bracket (1) with its rising when rising rotation, and driven rotary nut (41) pressed down upper bracket (1) with its reduction when screw rod (4) descended rotation.

The inboard contact surface with contract type pad (54) of described upper bracket tongue (11) is the inclined-plane, after bolt (5) is fastening with both, it is anti-big to internal pressure, the utility model lift manhole lid bearing adopts this bolt to connect the contract body technique, reaches that the combination between the upper and lower bearing is still firm purpose after the lift adjustment.

Operating procedure is, unclamps nut (53) earlier, and swivel nut (41) raises upper bracket (1) or is reduced to the target location again, nut (53) is tightened got final product complete operation at last.
