Detailed Description

In order to further understand the structure, characteristics and other objects of the present invention, the following detailed description is given with reference to the accompanying preferred embodiments, which are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention.

As shown in fig. 1 to 3, the utility model discloses an crab-bolt with failure alarm, including expand tube 1, bolt 2 and nut 3, the expand tube cup joints outside the bolt, and bolt one end is provided with countersunk head post 6, and the nut spiro union is at the bolt other end, and the expand tube is close to countersunk head post one end and has seted up expanding groove 7, and the crab-bolt is fixed to be set up in the mounting hole, and the injecting glue in the mounting hole, the crab-bolt outside is equipped with film pressure sensor 10 with the injecting glue contact surface, connects on the film pressure sensor and sets up the lead-out wire.

The countersunk head column is in a round table shape, the inclined surface of the countersunk head column points to the expansion groove, and the countersunk head column plays a role in guiding, so that the expansion pipe can be gradually expanded, and labor is saved during fastening. The bolt can be connected with the gasket 9 in series or not according to the situation.

The expand tube outside is equipped with sensor mounting groove 4, is provided with film pressure sensor 10 in the sensor mounting groove, and sensor mounting groove one side is equipped with wire casing 5, is provided with the lead-out wire in the wire casing, lead-out wire one end and film pressure sensor electric connection, and the other end is connected with external equipment.

The outer side of the countersunk head column is provided with a mounting groove 8, a film pressure sensor 10 is arranged in the mounting groove, one end of the outgoing line is electrically connected with the film pressure sensor, and the other end of the outgoing line is connected with external equipment. The film pressure sensor outside countersunk head post and the film pressure sensor outside the expand tube can set up simultaneously also can the alternative setting, and during the setting simultaneously, the pressure variation of gathering is more accurate, reduces the wrong report.

When the anchor bolt is fixed in the mounting hole after glue injection, the film pressure sensor deforms, namely resistance value changes, the pressure applied to the pressure sensor is used as initial state pressure, and the control module records the current value corresponding to the pressure sensor as an initial value; when the anchor bolt generates a loosening trend or a loosening trend relative to the glue injection, the pressure borne by the film pressure sensor is reduced, the deformation of the pressure sensor is reduced, the resistance value is correspondingly changed, the corresponding current value acquired by the control module is also changed, and when the change reaches a preset threshold value, a loosening warning is sent out, so that the risk of workers can be timely eliminated; similarly, when pressure increase, the pressure sensor resistance can change equally, reports to the police equally when reaching the abnormal conditions, the utility model discloses whether the crab-bolt is not hard up can be known to the change of utilization detection pressure value, through need not manual detection, sends the pressure situation through data transmission module, and the GPS module then can be sent the fixed position that the nut body corresponds the screw promptly together with pressure information simultaneously to in time arrive corresponding place for the staff.
