Abstract
The utility model provides a damping broadside inspection shaft lid, belongs to municipal construction technical field, including the well seat, articulate the well lid on the well seat with the help of the hinge, damping broadside inspection shaft lid still including setting up on the well seat and with well lid edge matched with damping mounting groove and set up the damping rubber strip in the damping mounting groove, the shape of the cross section of damping rubber strip is the notch cuttype that comprises square and isosceles trapezoid dislocation connection, bottom surface and damping rubber strip phase-match in the damping mounting groove. Through improving the shock attenuation part to the well lid, make it have simple structure, practicality strong, the effectual, the longe-lived characteristics of shock attenuation.
Description
Technical Field
The utility model belongs to the technical field of municipal construction, and particularly relates to a vibration-damping broadside inspection well cover.
Background
Sewer well lid is when the vehicle passes through, often sends the noise, not only causes certain noise pollution to urban environment, still influences well lid life. In the prior part of well lid products, rubber strips are additionally arranged on a well base to achieve the technical effects of vibration reduction and noise elimination, but the mounting grooves of the rubber strips are straight grooves, and the rubber strips are easy to adhere to the well lid after being used for a long time; when the well lid is opened, the rubber strips are easy to pull and break when the well lid is opened, so that the well lid is poor in noise prevention and shock absorption effects.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a vibration-damping wide-edge inspection well cover, which has the characteristics of simple structure, strong practicability, good vibration-damping effect and long service life by improving a vibration-damping component of the well cover.
The technical scheme adopted by the utility model is as follows: the utility model provides a damping broadside inspection well lid, includes the well seat, articulates the well lid on the well seat with the help of the hinge, damping broadside inspection well lid still including setting up on the well seat and with well lid edge matched with damping mounting groove and set up the damping rubber strip in the damping mounting groove, the notch cuttype that the cross section of damping rubber strip comprises square and isosceles trapezoid dislocation connection, bottom and damping rubber strip phase-match in the damping mounting groove.
Further, the square in the notch cuttype is at the upper left side of isosceles trapezoid.
Furthermore, the vibration damping rubber strips are arranged into 3-5 sections and are uniformly embedded into the vibration damping mounting grooves by taking the center of the well seat as the circumferential direction of the shaft.
Furthermore, the damping rubber strip is made of vulcanized chloroprene rubber, the content of chloroprene rubber is more than 40%, and the Shore A hardness is within the range of 75 +/-5.
The beneficial effects produced by adopting the utility model are as follows: the shock absorption component of the well lid is improved, so that the well lid has the characteristics of simple structure, strong practicability, good shock absorption effect and long service life; when the well lid is opened, the vibration reduction rubber strips can not be adhered to the well lid, the phenomenon that the well lid is broken due to dragging is avoided, and the noise-proof and vibration-reduction effects of the well lid are further guaranteed.

Detailed Description
Referring to fig. 1, a damping broadside manhole cover, including well seat 1, articulate the well lid 2 on well seat 1 with the help of hinge 3, damping broadside manhole cover still includes the setting on well seat 1 and with well lid 2 edge matched with damping mounting groove 1-1 and set up damping rubber strip 4 in damping mounting groove 1-1, the shape of the cross section of damping rubber strip 4 is the notch cuttype that comprises square and isosceles trapezoid dislocation connection, damping mounting groove 1-1 inner bottom and damping rubber strip 4 phase-match. The square is in isosceles trapezoid's upper left side in the notch cuttype. An adjusting ring 5 can be arranged at the lower part of the well seat 1.
As shown in fig. 2, the matching structure of the vibration damping rubber strip 4 and the vibration damping mounting groove 1-1 can bear the plumb and the horizontal load transmitted by the well lid 2, and the purposes of vibration damping and noise reduction are achieved.
As shown in figure 1, the vibration damping rubber strip 4 is arranged into 3-5 sections and is uniformly embedded into the vibration damping mounting groove 1-1 by taking the center of the well seat 1 as the axial circumference. The design can facilitate the installation and the maintenance of the damping rubber strip 4.
The vibration-damping rubber strip 4 is made of vulcanized chloroprene rubber, the content of chloroprene rubber is more than 40%, and the Shore A hardness is within the range of 75 +/-5. As shown in FIG. 3, the utility model performs finite element analysis, using AMG algorithm; under the action of 3 multiplied by 4000N plumb load, the plumb direction displacement of the vibration-damping rubber ring is 2.87mm, and the technical requirement of the DB510100 related local standard is completely met.
