Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

With reference to fig. 1-3, the strain type integrated narrow road weighing sensor comprises an integrated processing-formed elastic body 1, a strain gauge 2 and a cable 3 which are arranged on the elastic body 1 to form a wheatstone bridge, wherein grooves are formed in two sides of the elastic body 1, and anti-aging flexible substances 4 are filled in the grooves.

In order to further enhance the protection performance of the elastic body 1, flexible isolation layers 5 are respectively arranged on two sides of the elastic body 1, and the flexible isolation layers 5 cover the anti-aging flexible substance 4. In the present embodiment, the flexible isolation layer 5 is an adhesive tape bonded to the elastic body 1. Of course, other materials with flexible impact resistance, such as vulcanized rubber, may be used.

The sensor is mounted in the following way: and a groove is formed in the road surface, the whole sensor is placed in the groove, and glue is filled in a gap between the sensor and the groove, so that the installation is completed. In order to ensure the horizontal state of the sensor and the road surface, the top surface of the elastic body 1 is provided with a polishing layer 6, the polishing layer 6 can be polished by a polisher, and the horizontal state of the sensor and the road surface is ensured by changing the overall height of the sensor. In this embodiment, the polishing layer 6 is an epoxy wear-resistant adhesive layer, and other options include: metal, nylon material or other abradable material may be abraded.

The polishing layer 6 is smoothly connected to the elastic body 1, but the connection stability of the polishing layer 6 to the elastic body 1 may not be high, and the polishing layer 6 is easily peeled off. In order to increase the connection stability of the polishing layer 6 and the elastic body 1, a concave-convex structure is arranged between the polishing layer 6 and the elastic body 1. Specifically, the method comprises the following steps: the top surface of the elastic body 1 is provided with one or more than two clamping grooves 10 which are parallel to each other, when the polishing layer 6 (namely the epoxy wear-resistant adhesive layer) is coated on the top surface of the elastic body 1, the clamping grooves 10 increase the bonding area, and the connection stability of the polishing layer 6 and the elastic body 1 is improved.

The 5 both sides of flexible isolation layer are equipped with guard plate 7 that is used for increasing stability respectively, and guard plate 7 bonds on flexible isolation layer 5, has improved the stability ability of this sensor. The protection plate 7 may be fixedly connected to the elastic body 1 by a connection member, which is a bolt.

Among the above mentioned mounting ways of the sensor, mention may be made of: and placing the sensor into the groove, and pouring glue into a gap between the sensor and the groove. In order to improve the stability of the sensor, the bottom surface of the elastic body 1 is provided with a concave-convex structure for increasing the stability. Specifically, the method comprises the following steps: one or more than two parallel mounting grooves 11 are arranged on the bottom surface of the elastic body 1, the mounting grooves 11 increase the bonding area, and the stability of the sensor is improved.
