Problems solved by technology
[0003] In the tunnel construction of railway construction, the cables are fixed on the roof of the cave by anchor bolts. Usually, installation holes are drilled on the roof of the cave, and then glue is injected in the installation holes, and then the anchor bolts are inserted into the installation holes and surrounded by glue injection. Adjust the anchor bolt to expand the expansion tube and then block the installation hole. When the glue is solidified, the anchor bolt is firmly fixed in the installation hole, and the anchor bolt cooperates with the cable hoisted on the roof of the cave to maintain stability; Vibration. At this time, the anchor bolts on the roof of the tunnel may loosen due to the vibration. In severe cases, it will affect the safe running of the train. However, because the anchor bolts are fixed on the tunnel roof, traditional railway inspections can only rely on manual visual inspection one by one. And manual inspection, which consumes a lot of manpower, and inspection is time-consuming and laborious

Embodiment Construction
[0013] In order to further understand the structure, features and other purposes of the present invention, the attached preferred embodiments are now described in detail with accompanying drawings as follows. The embodiments described in the accompanying drawings are only used to illustrate the technical solutions of the present invention and are not limiting this invention.
[0014] Such as Figure 1 to Figure 3 As shown, the anchor bolt with failure alarm of the present invention includes an expansion tube 1, a bolt 2 and a nut 3, the expansion tube is sleeved outside the bolt, one end of the bolt is provided with a countersunk column 6, and the nut is screwed on the other end of the bolt, and the expansion tube is sleeved outside the bolt. The end of the tube close to the countersunk column is provided with an expansion groove 7, and the anchor bolt is fixed in the installation hole, and the glue is injected in the installation hole. A thin-film pressure sensor 10 is arrang...

The invention discloses an anchor bolt with the failure alarm function. The anchor bolt comprises an expansion tube, a bolt and a nut, the bolt is sleeved with the expansion tube, one end of the boltis provided with a countersunk head column, the nut is in screw joint to the other end of the bolt, the end, close to the countersunk head column, of the expanded tube is provided with an expansion groove, the anchor bolt is fixedly arranged in a mounting hole, glue is injected into the mounting hole, the contact face of the outer portion of the anchor bolt and the injected glue is provided with athin film pressure sensor, and a leading-out wire is connected to the thin film pressure sensor. When the anchor bolt loosens in the mounting hole, or injected glue drives the whole anchor bolt to slide off from the mounting hole, the pressure detected by the thin film pressure sensor is changed, when changing warning information and position information are sent to a remote server or client sidethrough a data transmission module, the alarm effect is achieved, in the detection process, naked eye identification is not needed, the detection precision is high, the alarm is in time, and the danger probability is reduced.
Description
technical field [0001] The invention relates to the field of fasteners, in particular to an anchor bolt with a failure alarm. Background technique [0002] Anchor bolts are generally referred to as expansion bolts. The anchor bolts are fixed by using the wedge-shaped slope to promote the expansion to generate friction and grip force to achieve the fixing effect; one end of the bolt is threaded, the other end has a taper, and the outer sleeve is covered with an expansion tube, half of which has a Several cutouts are stuffed into the mounting holes on the wall, and then the nuts are tightened. The nuts pull the bolts out of the holes, pull the taper into the expansion tube, and the expansion tube expands and inserts into the wall, so that the bolts are tightly fixed on the wall. Generally, it is used for engineering fastening. [0003] In the tunnel construction of railway construction, the cables are fixed on the roof of the cave by anchor bolts. Usually, installation holes ...
