Description

Technical Field

[0001] This utility model relates to the field of stress monitoring technology, and in particular to a stress monitoring device for bending members. Background Technology

[0002] After the slipform construction of the shallow circular silo, several radially distributed Bailey beams need to be installed on top. To monitor the bending stress state of the Bailey beams in real time, stress monitoring devices are typically installed at characteristic locations on the beams. Although there are many types of existing stress monitoring devices, such as strain gauges and non-contact stress probes, none of them are easy to install directly on the Bailey beams. Furthermore, due to variations in the width and thickness of the Bailey beams, different auxiliary devices are required for positioning the stress monitoring devices, making installation and disassembly inconvenient. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a stress monitoring device for bending members that is easier to install and disassemble and has greater versatility.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stress monitoring device for bending members includes an installation mechanism for connecting to the bending member and a non-contact stress monitoring probe. The installation mechanism includes a connecting seat and two parallel lead screw assemblies. The middle part of the lead screw assembly is connected to the connecting seat, and both ends of the lead screw assembly extend out of the connecting seat and are provided with limiting components at the ends for abutting and limiting the bending member's edge. The connecting seat has a cavity communicating with the bottom surface, and the top surface of the connecting seat has a connecting hole communicating with the cavity. The non-contact stress monitoring probe extends into the cavity from the connecting hole, and the non-contact stress monitoring probe is detachably connected to the connecting seat.

[0006] By adopting the above technical solution: the installation mechanism can be quickly installed on the bending member, and the positioning is achieved by the limiting components at both ends of the screw assembly abutting against the edge of the bending member; then the non-contact stress monitoring probe is inserted into the cavity and detachably connected to the connecting seat, making the installation and removal of the non-contact stress monitoring probe very convenient; since the position of the limiting component in the screw assembly is adjustable, it can be used to position bending members of different widths, and has strong versatility.

[0007] Preferably, the limiting assembly includes a limiting member and a first locking sleeve. The upper end of the limiting member is slidably connected to the lead screw assembly, and the first locking sleeve is disposed on the outside of the limiting member and threadedly connected to the lead screw assembly. After the limiting member moves to a suitable position on the lead screw assembly, it is locked and positioned by the first locking sleeve, thereby causing the limiting member to abut and be positioned against the edge of the bending member.

[0008] Preferably, the lower end of the limiting member has an inwardly bent limiting portion parallel to the lead screw assembly. The limiting portion has a threaded hole, and a locking bolt is installed inside the threaded hole. When the upper end of the locking bolt abuts against the bottom surface of the bending member, the bottom surface of the connecting seat abuts against the top surface of the bending member. By abutting the bottom surface of the bending member with the locking bolt, the connecting seat is further positioned, and simultaneously, the bottom surface of the connecting seat abuts against the top surface of the bending member. This closes the lower end of the cavity, making the non-contact stress monitoring probe more stable and less susceptible to interference when placed within the closed cavity.

[0009] Preferably, the connecting seat includes a base plate, a top plate, and a support block fixed between the base plates. The support block has a rectangular sliding hole. The lead screw assembly includes a slide rod slidably connected to the sliding hole and lead screw bodies fixed at both ends of the slide rod. The outer side of the support block has an elongated slot communicating with the sliding hole. A stud fixedly connected to the side of the slide rod is provided in the elongated slot, and a second locking sleeve is provided on the stud. Loosening the second locking sleeve allows for fine adjustment of the position of the connecting seat to meet the stress monitoring requirements at different locations of the bending member.

[0010] Preferably, the cavity is configured as a cylindrical cavity, and the non-contact stress monitoring probe is positioned on the centerline of the cylindrical cavity. A first sealing ring is provided on the bottom surface of the connecting seat corresponding to the lower end of the cylindrical cavity, and a second sealing ring is provided on the bottom surface of the connecting seat outside the first sealing ring. The first and second sealing rings further improve the waterproof performance, preventing rust and corrosion of the detection part from affecting the monitoring results; at the same time, they also improve the sealing of the cavity, making the non-contact stress monitoring probe less susceptible to moisture.

[0011] Preferably, the top surface of the connector is provided with a threaded sleeve that is coaxially distributed with the connecting hole, and the upper end of the non-contact stress monitoring probe is threadedly connected to the threaded sleeve; the non-contact stress monitoring probe is configured as an electromagnetic ultrasonic probe.

[0012] Therefore, this utility model has the advantages of convenient installation and disassembly and strong versatility. Attached Figure Description
