Abstract
The utility model relates to a pot-type rubber support for a bridge. A pot plug is arranged in a bottom pot of the pot-type rubber support in a matched mode, and a convex edge protruding outwards is arranged on the periphery of the upper portion of the pot plug. An elastic rubber cushion is arranged in the bottom pot, and the upper portion of the elastic rubber cushion corresponds to the pot plug. A side wall sensor hole and a bottom sensor hole are formed in the positions, corresponding to the side wall of the elastic rubber cushion and the bottom surface of the elastic rubber cushion, of the bottom pot respectively, a side wall sensor is arranged in the side wall sensor hole, and a bottom surface sensor is arranged in the bottom sensor hole. A pot plug sensor hole is formed in the position, corresponding to the top surface of the elastic rubber cushion, of the pot plug, and a pot plug sensor is arranged in the pot plug sensor hole. The side wall sensor, the bottom surface sensor and the pot plug sensor are all pressure sensors. According to the pot-type rubber support for the bridge, rubber is used as a pressure monitoring object, and pressure change reaction sensitivity is high so as to guarantee that information capture of the sensors is in time and in place. The sensors serving as measuring elements are isolated from the external environment, and negative influences of the external environment on monitored information are small.

Background technology
Pot rubber bearing, as connecting the critical product a kind of commonly used of bridge pier and beam body in bridge engineering, can provide for the beam body functions such as vertical bearing capacity, horizontal bearing capacity, horizontal slip, certain corner.Pot rubber bearing can be divided into fixed, one-way movable type (according to glide direction, being divided into longitudinally-moving type, horizontal active type), bi-directional movable type (also referred to as multidirectional active type) three classes according to the own level mobility.Pot rubber bearing, because of it above-mentioned functions possessed, also generally is applied in construction work simultaneously.Vertical bearing capacity is one of technical indicator of pot rubber bearing most critical.Pot rubber bearing is in the practical engineering application process, be subject to many-sided complex effects such as the deadweight of beam body, dynamic vehicle load, brake force, wind load, seismic forces, easily occur that vertical bearing capacity has exceeded the design limit scope, cause support damage and affect normal use and the application life of bridge, also can cause the bridge collapse accident in serious situation, cause large threat, destruction to the safety of vehicle, pedestrian, surrounding environment.Existing pot rubber bearing vertical bearing capacity monitoring technology, the disclosed pot rubber bearing with three-dimensional dynamometer device of bridge basin-type rubber support, Chinese patent ZL201020284478.9 with the monitoring configuration as disclosed as Chinese patent ZL200920103940.8, all to adopt ess-strain induction monitoring technology, have that monitoring reliability is not high, error is large, application life is short, monitoring system is not easy the problems such as demarcation, need to be solved.
The utility model content
In order to improve reliability, the monitoring accuracy of bearing capacity monitoring, in the application life of improving pot rubber bearing, the utility model provides a kind of pot rubber bearing for bridge that adopts Sensor monitoring.
Architecture advances of the present utility model is: monitoring mode, by structural stress, strain induction, changes the induction of rubber pad pressure on the one hand; On the other hand, the sensing element arrangement of monitoring use is changed into built-in by external.
Concrete technical scheme of the present utility model is as follows:
A kind of pot rubber bearing for bridge comprises the end basin of peviform, in end basin, coordinates and is provided with the basin plug, and the basin periphery of section beyond the Great Wall is provided with outwardly chimb; Be provided with rubber mat in end basin, the top correspondence of rubber mat the basin plug; Offer respectively sidewall gauge hole, bottom sensor hole on the end basin corresponding with the sidewall of rubber mat and bottom surface, be provided with the sidewall sensor in the sidewall gauge hole, be provided with the bottom surface sensor in the bottom sensor hole; The basin corresponding with the end face of rubber mat offers basin plug gauge hole beyond the Great Wall, is provided with basin plug sensor in basin plug gauge hole; Described sidewall sensor, bottom surface sensor and basin plug sensor are pressure sensor.
The top of described rubber mat is provided with the brass sealing ring.
Rubber mat all is close at the induction position of the induction position of sidewall sensor, the induction position of bottom surface sensor and basin plug sensor.
Useful technique effect body of the present utility model is: using elastomeric material as the pressure monitoring target, the reliability that can guarantee the pressure transmission because of its good mobility is high, the pressure change reaction sensitivity is high, tight with the sensor laminating, guarantees that the information capture of sensor is in time; Sensor is as single measuring cell, easier ensure quality stable, and improved the operability that monitoring element is demarcated; Sensor and external environment isolation, monitoring information is subject to the negative effect of external environment condition little, and has improved application life.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In upper figure, sequence number is: basin plug 1, brass sealing ring 2, rubber mat 3, end basin 4, bottom surface sensor 5, sidewall sensor 6, basin plug sensor 7, bottom sensor hole 8, sidewall gauge hole 9, basin plug gauge hole 10.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Embodiment
Referring to Fig. 1, a kind of pot rubber bearing for bridge comprises the end basin 4 of peviform, and basin plug 1 is equipped with in the interior cooperation of end basin 4, and the periphery on basin plug 1 top is provided with outwardly chimb.Rubber mat 3 is installed in end basin 4, and the top correspondence of rubber mat 3 basin plug 1; The top of rubber mat 3 is equipped with brass sealing ring 2.Offer respectively sidewall gauge hole 9, bottom sensor hole 8 on the end basin 4 corresponding with the sidewall of rubber mat 3 and bottom surface, sidewall sensor 6 is installed in the sidewall gauge hole, bottom surface sensor 5 is installed in bottom sensor hole 8; Offer basin plug gauge hole on the basin plug 1 corresponding with the end face of rubber mat, basin plug sensor 7 is installed in basin plug gauge hole 10; Rubber mat 3 all is close at the induction position of the induction position of sidewall sensor 6, the induction position of bottom surface sensor 5 and basin plug sensor 7.Sidewall sensor 6, bottom surface sensor 5 and basin plug sensor 7 are pressure sensor.
During work, rubber mat 3 gathers target as power transmission and pressure signal, it can be considered liquid under pressured state in the closed cavity of end basin 4 and basin plug 1 composition, utilize liquid Pascal's law (be added in the pressure size that is closed on liquid unchangeably by liquid to all directions transmission), the vertical bearing capacity of pot rubber bearing accurately can be obtained to (pressure of pot rubber bearing vertical bearing capacity=rubber mat * piston bottom surface bearing area) by pressure conversion; Pressure transmits to the cavity surrounding, and all directions pressure size is identical, can guarantee the degree of accuracy that pressure signal gathers; Elastomeric material is stable at the environment performance of sealing, can guarantee that application life is long-range.
