Technical Field

The invention relates to bridge bottom measuring piece mounting equipment in the field of bridge detection.

Background

Newly-built bridge and the bridge after having carried out reinforcement or reconstruction, whether normal operating condition and bearing capacity of bridge structures meet the design requirement can be examined through the load test.

It is common practice to pass a vehicle under a certain load through a bridge and then measure the strain, deflection and inclination deformation of the bridge according to corresponding sensors on the bridge. For example, for strain measurement, a surface sensor is fixed on the bottom surface of a beam, wherein the sensor is matched with the beam as shown in fig. 1, the sensor comprises two fixing legs 2 which are independently arranged, fixing holes for the corresponding fixing legs to pass through are respectively arranged on the body of a strain gauge 3, during specific operation, a worker is lifted to the lower side of the beam body 1 through a lifting machine, the worker measures the distance between the two fixing legs 2 on the bottom surface of the beam, then the fixing legs are fixedly bonded on the bottom surface of the beam, finally the strain gauge 3 is sleeved on the fixing legs, and the sensor is fixed on the supporting legs by screwing nuts 4 on screw rods 5 of the fixing legs. When the beam deforms due to a load, the distance between the two legs changes, and the sensor measures the amount of change.

When the bridge inclination angle needs to be measured, an inclination angle sensor is adhered and fixed to the bottom of the beam body, and various sensors are collectively called as measuring pieces. That is to say, the fixed sensor that all needs of various sensors is fixed with the roof beam body bottom surface bonding, among the prior art, during the bonding, need artifical rubber coating, artifical rubber coating just need lift personnel to the roof beam body bottom through elevating system, then artifical at roof beam body bottom surface rubber coating, fix corresponding sensor support again and bond in the roof beam body bottom, the rubber coating process in operating personnel high altitude, waste time and energy, and because there is the existence of this rubber coating step, also make the process of sensor installation must realize through personnel's operation, under the operating mode that is water to some roof beam body lower parts, because can't set up personnel climbing mechanism, consequently just can't detect corresponding bridge.

Therefore, the measuring part capable of automatically gluing is designed, the measuring part is jacked to the bottom of the beam body only by means of the corresponding jacking mechanism, but the existing jacking mechanism needs the ground as a carrier, for example, a jacking vehicle needs to be arranged on the ground, the arrangement of the jacking vehicle not only influences traffic, but also can not install the measuring part through the jacking mechanism for the water-crossing bridge with water at the bottom of some beam bodies.

In the process, the saccule on the sensor is punctured, the glue solution flows between the sensor and the bottom surface of the beam body, after the glue solution is solidified, the two winding drums on the left equipment support and the right equipment support are loosened, and corresponding strain detection can be carried out. After the detection is finished, the motor drives the pushing eccentric wheel to rotate, the pushing eccentric wheel pushes the beam body to separate the first supporting leg part and the second supporting leg part from the beam body, the sensor drops, the sensor cannot fall into water due to the existence of the jacking belt, then the right side part of the jacking belt is detached from the winding drum on the right side, and the winding drum on the equipment support on the left side is wound with a rope to move the sensor to the upper side of the bridge. Through the length and the angle of the telescopic rod, the reversing position of the jacking belt can be changed, namely the reversing fulcrum position of the jacking belt is changed, so that the jacking force can be adjusted, and the maximum jacking height of the sensor is adjusted.

In other embodiments of the invention: in order to realize the detachable connection of the right end of the jacking belt and the corresponding winding drum, the jacking belt coiling groove on the winding drum can be omitted, and the jacking belt can be directly wound on the winding drum; the winding drum can also not be driven by a driving mechanism, for example, the winding drum is rotated manually to realize the winding and unwinding of the jacking belt; the measuring part connecting structure can also be in other forms, for example, the jacking belt is a complete belt body, the measuring part is provided with a jacking belt through hole for the jacking belt to pass through along the left and right directions in a matching manner, the measuring part connecting structure comprises a contact matching section which is arranged in the jacking belt through hole in a penetrating manner and is in contact friction fit with the wall of the jacking belt through hole, and when the sensor is not adhered to the beam body, the sensor can be moved to a specified position by utilizing the friction force between the jacking belt and the sensor; only one belt connecting structure can be a tensioning connecting structure, for example, the right end of the jacking belt passes through the lower side of the beam body from left to right and then is directly fixed on the right equipment support, and the sensor can be lifted up and jacked to the bottom of the beam body by tensioning the jacking belt through the left belt connecting structure; tensioning of the jacking strap may of course also be achieved without a reel, for example by pulling one end of the jacking strap horizontally or vertically.
