Problems solved by technology

[0003] In the existing technology, due to the integrated shape of the finished support, it is difficult to monitor the force of the support. Even if there are some supports using sensing units, the detected information is relatively simple, and most technologies only install 1 sensor, the measurement error is relatively large. At the same time, the sensing unit of this kind of support is usually fixed with the support body or buried inside the support. Generally, the support needs to be processed, which will damage the support structure to a certain extent. , and to replace the sensing unit, the entire support needs to be replaced, which is costly and complicated to operate

Embodiment 1

[0027] refer to Figure 1-4 , the present invention provides a spot welding intelligent spherical bearing, comprising an upper bearing plate 1, the top of the upper bearing plate 1 is in contact with the beam body of the bridge, and the bottom of the upper bearing plate 1 is provided with a lower bearing plate 5, The bottom of the lower support plate 5 is firmly connected to the pier, a spherical crown is provided between the lower support plate 5 and the upper support plate 1, and the measuring instrument 7 is electrically connected to the spot welding sensor 6, which is used for measuring points The load-bearing pressure of the welding intelligent spherical bearing, the lower bearing plate 5 is provided with a basin ring, the spot welding sensor 6 is vertically arranged on the outer wall of the basin ring, the outer side of the lower bearing plate 5 is provided with a measuring instrument 7, and the spot welding sensor 6 and measuring instrument 7 are electrically connected....

Embodiment 2

[0038] The difference from Example 1 is that, referring to Figure 5 :

[0039] The outer wall of the spherical crown steel liner 3 is fixed with four laterally arranged spot welding sensors 6 at equal intervals in the circumferential direction.

[0040] To further optimize the scheme, the spot welding sensor 6 is integrated with the support structure, and the spot welding sensor 6 is fixed on the outer side of the spherical crown steel lining plate 3 by welding, and four spot welding sensors can be measured and calculated at the same time by connecting the wire and the measuring instrument 7 The average value can improve the accuracy and reliability of detection, and it is easy to install and replace, without causing damage to the structural performance of the support, and can realize long-term and real-time monitoring of the stress on the support.

[0041] To further optimize the scheme, the spot welding sensors 6 on the outside of the spherical crown steel lining plate 3 o...

Embodiment 3

[0043] The difference from Example 1 and Example 2 is that, referring to Figure 6 :

[0044] The top surface of the upper support plate 1 is respectively provided with a welding hole and a lead groove, the welding hole is arranged at the center of the upper support plate 1, the lead groove communicates with the welding hole, and two spot welding sensors 6 are vertically welded in the welding hole, and the point The signal output end of the welding sensor 6 is connected with a wire, and the wire is connected to the measuring instrument 7 through the lead groove, and the data measured by the spot welding sensor 6 can be obtained through the measuring instrument 7 .

[0045] By measuring the average value of 2 spot welding sensors 6 and monitoring the force of the spherical bearing, the measurement method is more accurate and effective, and the force measuring system of this spot welding intelligent spherical bearing is easy to install and replace, and will not affect the spheri...

Abstract

The invention discloses a spot welding intelligent spherical support which comprises an upper support plate, the top of the upper support plate abuts against a bridge body of a bridge, a lower support plate is arranged at the bottom of the upper support plate, the bottom of the lower support plate is fixedly connected with a bridge pier, a spherical crown body is arranged between the lower support plate and the upper support plate, and a measuring instrument is arranged on the outer side of the lower support plate. The spot welding sensors are electrically connected with the measuring instrument, the measuring instrument is electrically connected with the spot welding sensors, the spot welding sensors are used for measuring the bearing pressure of the spot welding intelligent spherical support, and the stress condition of the support is calculated and monitored by measuring the average value of the spot welding sensors. According to the spot welding intelligent spherical support, the stress condition of the spherical support can be monitored more accurately and effectively, the spot welding sensor is welded to the surface of the support component and is convenient to disassemble and replace, and the stress condition of the spherical support can be monitored for a long time in real time.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a spot welding intelligent spherical bearing. Background technique [0002] The support refers to the supporting part used to support the weight of the container or equipment and fix it in a certain position. It also bears the vibration and earthquake load during operation. It is generally used in bridges, buildings and other fields. The structure of the spherical support It is mainly composed of upper bearing plate, flat PTFE sliding plate, spherical crown steel lining plate, spherical PTFE sliding plate and lower bearing plate, among which the spherical crown steel lining plate is the core component of the spherical bearing and plays a role in bearing pressure. , rotation, and force transmission. [0003] In the existing technology, due to the integrated shape of the finished support, it is difficult to monitor the force of the support. Even if there are some supports using sensing unit...
