Abstract

The utility model provides a casting vibration reduction supporter consisting of a casting supporter and a high-strength anti-wear vibration reduction ring. The vibration reduction ring is embedded in a concave trough on the supporting surface of the casting supporter. The utility model has the advantages of difficult to be abraded and dropped, and convenient to be installed and replaced. The casting vibration reduction supporter can be used by being matched with a casting well cover or a steel fiber concrete well cover and can be stably combined with a well cover. When the vehicle is driven at high speed, the impact force to the well cover can be relieved, and the phenomena such as bounce, displacement, turnover, and noise, etc. do not occur to the well cover.

Description

The cast iron shock mount

One, technical field

The utility model relates to a kind of underground utility inspection shaft bearing with manhole cover, is meant a kind of the combination with well lid steadily especially, can alleviate impact force when vehicle crosses, and prevents that well lid from bouncing, the cast iron shock mount of sound of movement, displacement and upset.

Two, background technique

The manhole cover that tradition is used is because of not having damping device between well lid and the bearing, when vehicle crosses, spring and sound of movement can take place in well lid, even be subjected to displacement or flop phenomenon, the former will make vehicle jolt and take uncomfortable and influence environment, and the latter is the safety of entail dangers to pedestrian and vehicle then.In order to address this problem, the face of shelving at well lid that has (with the surface of contact of bearing support face) is pasted a circle rubber seal, though produce effect, needs often to open well lid when safeguarding underground utility, and rubber band is easy to be worn or come off, so that loses effectiveness.In addition, the bearing of existing manhole cover is and directly is shelved on the masonry of checking well bore, uses soon, the crack will appear in bearing and road surface intersection, and crisp broken phenomenon will take place road surface, infiltration back, is " the mashed limit " that be commonly called as, the lighter hinders attractive in appearance, and is heavy then become potential safety hazard.

Three, summary of the invention

The purpose of this utility model just is to overcome the defective of background technique, and a kind of long service life is provided, and can prevent that when vehicle crosses well lid from beating and make a noise, and combine tightly with the road surface, can not produce the cast iron shock mount of " mashed limit " phenomenon.

The purpose of this utility model is realized by following scheme:

The utility model cast iron shock mount is made of cast iron bearing and damping ring, and is fluted on the supporting surface of cast iron bearing, and damping ring is embedded in the groove;

The cross section of its supporting surface upper groove of cast iron bearing of the utility model cast iron shock mount is U-shaped or rectangle or swallow-tail form;

The damping ring of the utility model cast iron shock mount is ring-type or segmentation, and its cross section is O shape, rectangle or trapezoidal;

The cast iron bearing of the utility model cast iron shock mount has flange, and the bolt hole of circle or ellipse or waist-hole type is arranged on the flange.

The utility model is compared with background technique, has following advantage and effect:

Long service life; Can be used with casting iron well lid or steel fibre concrete well lid and combine steadily with well lid; When vehicle crosses at a high speed, can alleviate its impact force, well lid not produced beat, sound, displacement and upset well lid; Damping ring is difficult for being worn and comes off and change conveniently; Bearing becomes an integral body with the walling crib of checking well bore with the bolt rivet clasp, has fundamentally solved " mashed limit " difficult problem, thereby the smooth-ride of assurance vehicle is passed through; When especially on the road of asphalt pavement, using, not fragile in pavement construction or road upkeep, can reuse and need not change.Therefore the utility model has good popularization and application prospect as the steady bearing of damping.

Four, description of drawings

Accompanying drawing is a generalized section of the present utility model.

(1) shown in the figure is that cast iron bearing, (2) are that bolt hole, (7) be flange for groove, (5) for well lid, (6) for damping ring, (4) for supporting surface, (3).

Five, embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.The utility model is not limited to following examples.

With reference to accompanying drawing, the utility model is made of cast iron bearing (1) and damping ring (3).On the supporting surface (2) of cast iron bearing (1) annular groove (4) is arranged, the cross section of groove (4) is U-shaped or rectangle, deviates from from groove (4) for preventing damping ring (3), also the cross section of groove (4) can be made into swallow-tail form.With the cross section is after the ring-type high-strength abrasion-proof shock absorbing rubber circle (3) of O shape or rectangle or swallow-tail form applies glue, firmly embed in the groove (4), the surface of damping ring (3) should be higher than supporting surface (2), so that well lid (5) covers and plays damping steadily act on when bearing (1) is gone up.For prevent that damping ring (3) from because of the heat expansion effect, deviating from from groove (4), can adopt the damping ring of segmented, be about to damping ring and be made into plurality of sections, segmentation embeds in the groove (4), leaves a fixed gap between each section and gets final product.Join together for cast iron bearing (1) being fixedly secured on the walling crib of checking well bore, can go up the bolt hole (6) of reserving several circles or ellipse or waist-hole type at the flange (7) of cast iron (1), cast iron bearing (1) is fixed on the walling crib of checking well bore with bolt during installation, to prevent " mashed limit " phenomenon.

Claims

1. a cast iron shock mount is characterized in that the cast iron shock mount is made of cast iron bearing and damping ring, and fluted on the supporting surface of cast iron bearing, damping ring is embedded in the groove.
